-Submitted By: DJ Lucas (dj at linuxfromscratch dot org)

-+# Updated to iproute2 by Jim Gifford (scripts@jg555.com)
-
- # Notes:
-
- # 0. This script is based on the netbsd script supplied with dhcp-970306.
--
--# 1. ifconfig down apparently deletes all relevant routes and flushes
--# the arp cache, so this doesn't need to be done explicitly.
--
--# 2. The alias address handling here has not been tested AT ALL.
--# I'm just going by the doc of modern Linux ip aliasing, which uses
--# notations like eth0:0, eth0:1, for each alias.
--
--# 3. I have to calculate the network address, and calculate the broadcast
--# address if it is not supplied. This might be much more easily done
--# by the dhclient C code, and passed on.
--
--# 4. TIMEOUT not tested. ping has a flag I don't know, and I'm suspicious
--# of the $1 in its args.
-+# 1. This script was modified to work with iproute2
-+# 2. cidr_convert based on a script by Kevin Fleming (kpfleming@linuxfromscratch.org)
-+# 3. Updated to delete addresses when taking an interface down (bdubbs@linuxfromscratch.org)

-+ *
-+ * The first version was written by Martin Devera, <devik@cdi.cz>
-+ *
-+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
-+ * - Update patch to 2.4.21
-+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
-+ * - Fix "Dead-loop on netdevice imq"-issue
-+ * Marcel Sebek <sebek64@post.cz>
-+ * - Update to 2.6.2-rc1
-+ *
-+ * After some time of inactivity there is a group taking care
-+ * of IMQ again: http://www.linuximq.net
-+ *
-+ *
-+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
-+ * the following changes:
-+ *
-+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
-+ * - Correction of imq_init_devs() issue that resulted in
-+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
-+ * - Addition of functionality to choose number of IMQ devices
-+ * during kernel config (Andre Correa)
-+ * - Addition of functionality to choose how IMQ hooks on
-+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
-+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
-+ *
-+ *
-+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
-+ * released with almost no problems. 2.6.14-x was released
-+ * with some important changes: nfcache was removed; After
-+ * some weeks of trouble we figured out that some IMQ fields
-+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
-+ * These functions are correctly patched by this new patch version.
-+ *
-+ * Thanks for all who helped to figure out all the problems with
-+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
-+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
-+ * I didn't forget anybody). I apologize again for my lack of time.

-+// Dr B. R. Gladman <brg@gladman.uk.net> 6th April 2001.

-+// This is an implementation of the AES encryption algorithm (Rijndael)
-+// designed by Joan Daemen and Vincent Rijmen. This version is designed
-+// to provide both fixed and dynamic block and key lengths and can also
-+// run with either big or little endian internal byte order (see aes.h).
-+// It inputs block and key lengths in bytes with the legal values being
-+// 16, 24 and 32.
-+
-+/*
-+ * Modified by Jari Ruusu, May 1 2001
-+ * - Fixed some compile warnings, code was ok but gcc warned anyway.
-+ * - Changed basic types: byte -> unsigned char, word -> u_int32_t
-+ * - Major name space cleanup: Names visible to outside now begin
-+ * with "aes_" or "AES_". A lot of stuff moved from aes.h to aes.c
-+ * - Removed C++ and DLL support as part of name space cleanup.
-+ * - Eliminated unnecessary recomputation of tables. (actual bug fix)
-+ * - Merged precomputed constant tables to aes.c file.
-+ * - Removed data alignment restrictions for portability reasons.
-+ * - Made block and key lengths accept bit count (128/192/256)
-+ * as well byte count (16/24/32).
-+ * - Removed all error checks. This change also eliminated the need
-+ * to preinitialize the context struct to zero.
-+ * - Removed some totally unused constants.

-+ The output has been subject to swaps of the form
-+ 0 1 -> 3 1 but the odd and even bits have been put into
-+ 2 3 2 0
-+ different words. The main trick is to remember that
-+ t=((l>>size)^r)&(mask);
-+ r^=t;
-+ l^=(t<<size);
-+ can be used to swap and move bits between words.
-+
-+ So l = 0 1 2 3 r = 16 17 18 19

-+ Thanks for hints from Richard Outerbridge - he told me IP&FP

-+ When I finally started to think of the problem in 2D

-+/* SAs are held in a table.
-+ * Entries in this table are referenced by IPsecSAref_t values.
-+ * IPsecSAref_t values are conceptually subscripts. Because
-+ * we want to allocate the table piece-meal, the subscripting
-+ * is implemented with two levels, a bit like paged virtual memory.
-+ * This representation mechanism is known as an Iliffe Vector.
-+ *
-+ * The Main table (AKA the refTable) consists of 2^IPSEC_SA_REF_MAINTABLE_IDX_WIDTH
-+ * pointers to subtables.
-+ * Each subtable has 2^IPSEC_SA_REF_SUBTABLE_IDX_WIDTH entries, each of which
-+ * is a pointer to an SA.
-+ *
-+ * An IPsecSAref_t contains either an exceptional value (signified by the
-+ * high-order bit being on) or a reference to a table entry. A table entry
-+ * reference has the subtable subscript in the low-order
-+ * IPSEC_SA_REF_SUBTABLE_IDX_WIDTH bits and the Main table subscript
-+ * in the next lowest IPSEC_SA_REF_MAINTABLE_IDX_WIDTH bits.
-+ *
-+ * The Maintable entry for an IPsecSAref_t x, a pointer to its subtable, is
-+ * IPsecSAref2table(x). It is of type struct IPsecSArefSubTable *.
-+ *
-+ * The pointer to the SA for x is IPsecSAref2SA(x). It is of type
-+ * struct ipsec_sa*. The macro definition clearly shows the two-level
-+ * access needed to find the SA pointer.
-+ *
-+ * The Maintable is allocated when IPsec is initialized.
-+ * Each subtable is allocated when needed, but the first is allocated
-+ * when IPsec is initialized.
-+ *
-+ * IPsecSAref_t is designed to be smaller than an NFmark so that
-+ * they can be stored in NFmarks and still leave a few bits for other
-+ * purposes. The spare bits are in the low order of the NFmark
-+ * but in the high order of the IPsecSAref_t, so conversion is required.
-+ * We pick the upper bits of NFmark on the theory that they are less likely to
-+ * interfere with more pedestrian uses of nfmark.

-+ deflate compresses as much data as possible, and stops when the input
-+ buffer becomes empty or the output buffer becomes full. It may introduce some
-+ output latency (reading input without producing any output) except when
-+ forced to flush.
-+
-+ The detailed semantics are as follows. deflate performs one or both of the
-+ following actions:
-+
-+ - Compress more input starting at next_in and update next_in and avail_in
-+ accordingly. If not all input can be processed (because there is not
-+ enough room in the output buffer), next_in and avail_in are updated and
-+ processing will resume at this point for the next call of deflate().
-+
-+ - Provide more output starting at next_out and update next_out and avail_out
-+ accordingly. This action is forced if the parameter flush is non zero.
-+ Forcing flush frequently degrades the compression ratio, so this parameter
-+ should be set only when necessary (in interactive applications).
-+ Some output may be provided even if flush is not set.
-+
-+ Before the call of deflate(), the application should ensure that at least
-+ one of the actions is possible, by providing more input and/or consuming
-+ more output, and updating avail_in or avail_out accordingly; avail_out
-+ should never be zero before the call. The application can consume the
-+ compressed output when it wants, for example when the output buffer is full

-+ and with zero avail_out, it must be called again after making room in the
-+ output buffer because there might be more output pending.
-+
-+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
-+ flushed to the output buffer and the output is aligned on a byte boundary, so
-+ that the decompressor can get all input data available so far. (In particular
-+ avail_in is zero after the call if enough output space has been provided
-+ before the call.) Flushing may degrade compression for some compression
-+ algorithms and so it should be used only when necessary.
-+
-+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
-+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
-+ restart from this point if previous compressed data has been damaged or if
-+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
-+ the compression.
-+
-+ If deflate returns with avail_out == 0, this function must be called again
-+ with the same value of the flush parameter and more output space (updated
-+ avail_out), until the flush is complete (deflate returns with non-zero
-+ avail_out).

-+ more input data, until it returns with Z_STREAM_END or an error. After
-+ deflate has returned Z_STREAM_END, the only possible operations on the
-+ stream are deflateReset or deflateEnd.
-+
-+ Z_FINISH can be used immediately after deflateInit if all the compression
-+ is to be done in a single step. In this case, avail_out must be at least
-+ 0.1% larger than avail_in plus 12 bytes. If deflate does not return

-+/*
-+ inflate decompresses as much data as possible, and stops when the input
-+ buffer becomes empty or the output buffer becomes full. It may some
-+ introduce some output latency (reading input without producing any output)
-+ except when forced to flush.
-+
-+ The detailed semantics are as follows. inflate performs one or both of the
-+ following actions:
-+
-+ - Decompress more input starting at next_in and update next_in and avail_in
-+ accordingly. If not all input can be processed (because there is not
-+ enough room in the output buffer), next_in is updated and processing
-+ will resume at this point for the next call of inflate().
-+
-+ - Provide more output starting at next_out and update next_out and avail_out
-+ accordingly. inflate() provides as much output as possible, until there
-+ is no more input data or no more space in the output buffer (see below
-+ about the flush parameter).
-+
-+ Before the call of inflate(), the application should ensure that at least
-+ one of the actions is possible, by providing more input and/or consuming
-+ more output, and updating the next_* and avail_* values accordingly.
-+ The application can consume the uncompressed output when it wants, for
-+ example when the output buffer is full (avail_out == 0), or after each
-+ call of inflate(). If inflate returns Z_OK and with zero avail_out, it
-+ must be called again after making room in the output buffer because there
-+ might be more output pending.
-+
-+ If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
-+ output as possible to the output buffer. The flushing behavior of inflate is
-+ not specified for values of the flush parameter other than Z_SYNC_FLUSH
-+ and Z_FINISH, but the current implementation actually flushes as much output
-+ as possible anyway.
-+
-+ inflate() should normally be called until it returns Z_STREAM_END or an
-+ error. However if all decompression is to be performed in a single step
-+ (a single call of inflate), the parameter flush should be set to
-+ Z_FINISH. In this case all pending input is processed and all pending
-+ output is flushed; avail_out must be large enough to hold all the
-+ uncompressed data. (The size of the uncompressed data may have been saved
-+ by the compressor for this purpose.) The next operation on this stream must
-+ be inflateEnd to deallocate the decompression state. The use of Z_FINISH
-+ is never required, but can be used to inform inflate that a faster routine
-+ may be used for the single inflate() call.
-+
-+ If a preset dictionary is needed at this point (see inflateSetDictionary
-+ below), inflate sets strm-adler to the adler32 checksum of the
-+ dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise
-+ it sets strm->adler to the adler32 checksum of all output produced
-+ so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
-+ an error code as described below. At the end of the stream, inflate()
-+ checks that its computed adler32 checksum is equal to that saved by the
-+ compressor and returns Z_STREAM_END only if the checksum is correct.
-+
-+ inflate() returns Z_OK if some progress has been made (more input processed
-+ or more output produced), Z_STREAM_END if the end of the compressed data has
-+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
-+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
-+ corrupted (input stream not conforming to the zlib format or incorrect
-+ adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
-+ (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
-+ enough memory, Z_BUF_ERROR if no progress is possible or if there was not

-+
-+ The method parameter is the compression method. It must be Z_DEFLATED in
-+ this version of the library.
-+
-+ The windowBits parameter is the base two logarithm of the window size
-+ (the size of the history buffer). It should be in the range 8..15 for this

-+ compression at the expense of memory usage. The default value is 15 if
-+ deflateInit is used instead.
-+
-+ The memLevel parameter specifies how much memory should be allocated
-+ for the internal compression state. memLevel=1 uses minimum memory but
-+ is slow and reduces compression ratio; memLevel=9 uses maximum memory
-+ for optimal speed. The default value is 8. See zconf.h for total memory
-+ usage as a function of windowBits and memLevel.
-+
-+ The strategy parameter is used to tune the compression algorithm. Use the
-+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-+ filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
-+ string match). Filtered data consists mostly of small values with a

-+ The dictionary should consist of strings (byte sequences) that are likely

-+zlib 1.1.4 is a general purpose data compression library. All the code
-+is thread safe. The data format used by the zlib library
-+is described by RFCs (Request for Comments) 1950 to 1952 in the files
-+http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate
-+format) and rfc1952.txt (gzip format). These documents are also available in
-+other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
-+
-+All functions of the compression library are documented in the file zlib.h
-+(volunteer to write man pages welcome, contact jloup@gzip.org). A usage
-+example of the library is given in the file example.c which also tests that
-+the library is working correctly. Another example is given in the file
-+minigzip.c. The compression library itself is composed of all source files
-+except example.c and minigzip.c.
-+
-+To compile all files and run the test program, follow the instructions
-+given at the top of Makefile. In short "make test; make install"
-+should work for most machines. For Unix: "./configure; make test; make install"
-+For MSDOS, use one of the special makefiles such as Makefile.msc.
-+For VMS, use Make_vms.com or descrip.mms.
-+
-+Questions about zlib should be sent to <zlib@gzip.org>, or to
-+Gilles Vollant <info@winimage.com> for the Windows DLL version.
-+The zlib home page is http://www.zlib.org or http://www.gzip.org/zlib/
-+Before reporting a problem, please check this site to verify that
-+you have the latest version of zlib; otherwise get the latest version and
-+check whether the problem still exists or not.
-+
-+PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html
-+before asking for help.
-+
-+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
-+issue of Dr. Dobb's Journal; a copy of the article is available in
-+http://dogma.net/markn/articles/zlibtool/zlibtool.htm
-+
-+The changes made in version 1.1.4 are documented in the file ChangeLog.
-+The only changes made since 1.1.3 are bug corrections:
-+
-+- ZFREE was repeated on same allocation on some error conditions.
-+ This creates a security problem described in
-+ http://www.zlib.org/advisory-2002-03-11.txt
-+- Returned incorrect error (Z_MEM_ERROR) on some invalid data
-+- Avoid accesses before window for invalid distances with inflate window
-+ less than 32K.
-+- force windowBits > 8 to avoid a bug in the encoder for a window size
-+ of 256 bytes. (A complete fix will be available in 1.1.5).
-+
-+The beta version 1.1.5beta includes many more changes. A new official
-+version 1.1.5 will be released as soon as extensive testing has been
-+completed on it.
-+
-+
-+Unsupported third party contributions are provided in directory "contrib".
-+
-+A Java implementation of zlib is available in the Java Development Kit
-+http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html
-+See the zlib home page http://www.zlib.org for details.
-+
-+A Perl interface to zlib written by Paul Marquess <pmarquess@bfsec.bt.co.uk>
-+is in the CPAN (Comprehensive Perl Archive Network) sites
-+http://www.cpan.org/modules/by-module/Compress/
-+
-+A Python interface to zlib written by A.M. Kuchling <amk@magnet.com>
-+is available in Python 1.5 and later versions, see
-+http://www.python.org/doc/lib/module-zlib.html
-+
-+A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com>
-+is availlable at http://www.westend.com/~kupries/doc/trf/man/man.html
-+
-+An experimental package to read and write files in .zip format,
-+written on top of zlib by Gilles Vollant <info@winimage.com>, is
-+available at http://www.winimage.com/zLibDll/unzip.html
-+and also in the contrib/minizip directory of zlib.
-+
-+
-+Notes for some targets:
-+
-+- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
-+ and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
-+ The zlib DLL support was initially done by Alessandro Iacopetti and is
-+ now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
-+ home page at http://www.winimage.com/zLibDll
-+
-+ From Visual Basic, you can call the DLL functions which do not take
-+ a structure as argument: compress, uncompress and all gz* functions.
-+ See contrib/visual-basic.txt for more information, or get
-+ http://www.tcfb.com/dowseware/cmp-z-it.zip
-+
-+- For 64-bit Irix, deflate.c must be compiled without any optimization.
-+ With -O, one libpng test fails. The test works in 32 bit mode (with
-+ the -n32 compiler flag). The compiler bug has been reported to SGI.
-+
-+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1
-+ it works when compiled with cc.
-+
-+- on Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1
-+ is necessary to get gzprintf working correctly. This is done by configure.
-+
-+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works
-+ with other compilers. Use "make test" to check your compiler.
-+
-+- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
-+
-+- For Turbo C the small model is supported only with reduced performance to
-+ avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
-+
-+- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html
-+ Per Harald Myrvang <perm@stud.cs.uit.no>
-+
-+
-+Acknowledgments:
-+
-+ The deflate format used by zlib was defined by Phil Katz. The deflate
-+ and zlib specifications were written by L. Peter Deutsch. Thanks to all the
-+ people who reported problems and suggested various improvements in zlib;
-+ they are too numerous to cite here.

-+
-+/*
-+ * Modified by Jari Ruusu, May 1 2001
-+ * - Fixed some compile warnings, code was ok but gcc warned anyway.
-+ * - Changed basic types: byte -> unsigned char, word -> u_int32_t
-+ * - Major name space cleanup: Names visible to outside now begin
-+ * with "aes_" or "AES_". A lot of stuff moved from aes.h to aes.c
-+ * - Removed C++ and DLL support as part of name space cleanup.
-+ * - Eliminated unnecessary recomputation of tables. (actual bug fix)
-+ * - Merged precomputed constant tables to aes.c file.
-+ * - Removed data alignment restrictions for portability reasons.
-+ * - Made block and key lengths accept bit count (128/192/256)
-+ * as well byte count (16/24/32).
-+ * - Removed all error checks. This change also eliminated the need
-+ * to preinitialize the context struct to zero.
-+ * - Removed some totally unused constants.

-+// CONFIGURATION OPTIONS (see also aes.h)
-+//
-+// 1. Define UNROLL for full loop unrolling in encryption and decryption.
-+// 2. Define PARTIAL_UNROLL to unroll two loops in encryption and decryption.
-+// 3. Define FIXED_TABLES for compiled rather than dynamic tables.
-+// 4. Define FF_TABLES to use tables for field multiplies and inverses.
-+// Do not enable this without understanding stack space requirements.
-+// 5. Define ARRAYS to use arrays to hold the local state block. If this
-+// is not defined, individually declared 32-bit words are used.
-+// 6. Define FAST_VARIABLE if a high speed variable block implementation
-+// is needed (essentially three separate fixed block size code sequences)
-+// 7. Define either ONE_TABLE or FOUR_TABLES for a fast table driven
-+// version using 1 table (2 kbytes of table space) or 4 tables (8
-+// kbytes of table space) for higher speed.
-+// 8. Define either ONE_LR_TABLE or FOUR_LR_TABLES for a further speed
-+// increase by using tables for the last rounds but with more table
-+// space (2 or 8 kbytes extra).
-+// 9. If neither ONE_TABLE nor FOUR_TABLES is defined, a compact but
-+// slower version is provided.
-+// 10. If fast decryption key scheduling is needed define ONE_IM_TABLE
-+// or FOUR_IM_TABLES for higher speed (2 or 8 kbytes extra).

-+/*
-+ * ALGORITHM
-+ *
-+ * The "deflation" process depends on being able to identify portions
-+ * of the input text which are identical to earlier input (within a
-+ * sliding window trailing behind the input currently being processed).
-+ *
-+ * The most straightforward technique turns out to be the fastest for
-+ * most input files: try all possible matches and select the longest.
-+ * The key feature of this algorithm is that insertions into the string
-+ * dictionary are very simple and thus fast, and deletions are avoided
-+ * completely. Insertions are performed at each input character, whereas
-+ * string matches are performed only when the previous match ends. So it
-+ * is preferable to spend more time in matches to allow very fast string
-+ * insertions and avoid deletions. The matching algorithm for small
-+ * strings is inspired from that of Rabin & Karp. A brute force approach
-+ * is used to find longer strings when a small match has been found.
-+ * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
-+ * (by Leonid Broukhis).
-+ * A previous version of this file used a more sophisticated algorithm
-+ * (by Fiala and Greene) which is guaranteed to run in linear amortized
-+ * time, but has a larger average cost, uses more memory and is patented.
-+ * However the F&G algorithm may be faster for some highly redundant
-+ * files if the parameter max_chain_length (described below) is too large.
-+ *
-+ * ACKNOWLEDGEMENTS
-+ *
-+ * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
-+ * I found it in 'freeze' written by Leonid Broukhis.
-+ * Thanks to many people for bug reports and testing.

-+Check the CC and CFLAGS lines in the makefile
-+
-+If your C library does not support the times(3) function, change the
-+#define TIMES to
-+#undef TIMES in speed.c
-+If it does, check the HZ value for the times(3) function.
-+If your system does not define CLK_TCK it will be assumed to
-+be 100.0.
-+
-+If possible use gcc v 2.7.?
-+Turn on the maximum optimising (normally '-O3 -fomit-frame-pointer' for gcc)
-+In recent times, some system compilers give better performace.
-+
-+type 'make'
-+
-+run './destest' to check things are ok.
-+run './rpw' to check the tty code for reading passwords works.
-+run './speed' to see how fast those optimisations make the library run :-)
-+run './des_opts' to determin the best compile time options.
-+
-+The output from des_opts should be put in the makefile options and des_enc.c
-+should be rebuilt. For 64 bit computers, do not use the DES_PTR option.
-+For the DEC Alpha, edit des.h and change DES_LONG to 'unsigned int'
-+and then you can use the 'DES_PTR' option.
-+
-+The file options.txt has the options listed for best speed on quite a
-+few systems. Look and the options (UNROLL, PTR, RISC2 etc) and then
-+turn on the relevent option in the Makefile
-+
-+There are some special Makefile targets that make life easier.
-+make cc - standard cc build
-+make gcc - standard gcc build
-+make x86-elf - x86 assembler (elf), linux-elf.
-+make x86-out - x86 assembler (a.out), FreeBSD
-+make x86-solaris- x86 assembler
-+make x86-bsdi - x86 assembler (a.out with primative assembler).
-+
-+If at all possible use the assembler (for Windows NT/95, use
-+asm/win32.obj to link with). The x86 assembler is very very fast.
-+
-+A make install will by default install
-+libdes.a in /usr/local/lib/libdes.a
-+des in /usr/local/bin/des
-+des_crypt.man in /usr/local/man/man3/des_crypt.3
-+des.man in /usr/local/man/man1/des.1
-+des.h in /usr/include/des.h
-+
-+des(1) should be compatible with sunOS's but I have been unable to
-+test it.
-+
-+These routines should compile on MSDOS, most 32bit and 64bit version
-+of Unix (BSD and SYSV) and VMS, without modification.
-+The only problems should be #include files that are in the wrong places.
-+
-+These routines can be compiled under MSDOS.
-+I have successfully encrypted files using des(1) under MSDOS and then
-+decrypted the files on a SparcStation.
-+I have been able to compile and test the routines with
-+Microsoft C v 5.1 and Turbo C v 2.0.
-+The code in this library is in no way optimised for the 16bit
-+operation of MSDOS.
-+
-+When building for glibc, ignore all of the above and just unpack into
-+glibc-1.??/des and then gmake as per normal.
-+
-+As a final note on performace. Certain CPUs like sparcs and Alpha often give
-+a %10 speed difference depending on the link order. It is rather anoying
-+when one program reports 'x' DES encrypts a second and another reports
-+'x*0.9' the speed.

-+libdes is now also shipped with SSLeay. Primary ftp site of
-+ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/SSLeay-x.x.x.tar.gz
-+
-+The best way to build this library is to build it as part of SSLeay.
-+
-+This kit builds a DES encryption library and a DES encryption program.
-+It supports ecb, cbc, ofb, cfb, triple ecb, triple cbc, triple ofb,
-+triple cfb, desx, and MIT's pcbc encryption modes and also has a fast
-+implementation of crypt(3).
-+It contains support routines to read keys from a terminal,
-+generate a random key, generate a key from an arbitrary length string,
-+read/write encrypted data from/to a file descriptor.
-+
-+The implementation was written so as to conform with the manual entry
-+for the des_crypt(3) library routines from MIT's project Athena.
-+
-+destest should be run after compilation to test the des routines.
-+rpw should be run after compilation to test the read password routines.
-+The des program is a replacement for the sun des command. I believe it
-+conforms to the sun version.
-+
-+The Imakefile is setup for use in the kerberos distribution.
-+
-+These routines are best compiled with gcc or any other good
-+optimising compiler.
-+Just turn you optimiser up to the highest settings and run destest
-+after the build to make sure everything works.
-+
-+I believe these routines are close to the fastest and most portable DES
-+routines that use small lookup tables (4.5k) that are publicly available.
-+The fcrypt routine is faster than ufc's fcrypt (when compiling with
-+gcc2 -O2) on the sparc 2 (1410 vs 1270) but is not so good on other machines
-+(on a sun3/260 168 vs 336). It is a function of CPU on chip cache size.
-+[ 10-Jan-97 and a function of an incorrect speed testing program in
-+ ufc which gave much better test figures that reality ].
-+
-+It is worth noting that on sparc and Alpha CPUs, performance of the DES
-+library can vary by upto %10 due to the positioning of files after application
-+linkage.

-+The only changes the FreeS/WAN project has made to libdes-lite 4.04b are:
-+
-+We #ifdef-ed the declaration of DES_LONG in des.h, so it's more efficient
-+on the Alpha, instead of just noting the issue in a comment.
-+
-+We #ifdef-ed out the des_options() function in ecb_enc.c, because we don't

-+is built as a module (depending on details of Linux configuration options).
-+
-+We changed some instances of CC=$(CC) in the Makefile to CC='$(CC)' to make
-+it cope better with Linux kernel Makefile stupidities, and took out an
-+explicit CC=gcc (unwise on systems with strange compilers).
-+
-+We deleted some references to <stdio.h> and <stdlib.h>, and a declaration
-+of one function found only in the full libdes (not in libdes-lite), to
-+avoid dragging in bits of stdio/stdlib unnecessarily. (Our thanks to Hans
-+Schultz for spotting this and pointing out the fixes.)
-+
-+We deleted a couple of .obj files in the asm subdirectory, which appear to
-+have been included in the original library by accident.

-+Version 4.04
-+ Fixed a few tests in destest. Also added x86 assember for
-+ des_ncbc_encrypt() which is the standard cbc mode function.
-+ This makes a very very large performace difference.
-+ Ariel Glenn ariel@columbia.edu reports that the terminal
-+ 'turn echo off' can return (errno == EINVAL) under solaris
-+ when redirection is used. So I now catch that as well as ENOTTY.
-+
-+
-+Version 4.03
-+ Left a static out of enc_write.c, which caused to buffer to be
-+ continiously malloc()ed. Does anyone use these functions? I keep
-+ on feeling like removing them since I only had these in there
-+ for a version of kerberised login. Anyway, this was pointed out
-+ by Theo de Raadt <deraadt@cvs.openbsd.org>
-+ The 'n' bit ofb code was wrong, it was not shifting the shift
-+ register. It worked correctly for n == 64. Thanks to
-+ Gigi Ankeny <Gigi.Ankeny@Eng.Sun.COM> for pointing this one out.
-+
-+Version 4.02
-+ I was doing 'if (memcmp(weak_keys[i],key,sizeof(key)) == 0)'
-+ when checking for weak keys which is wrong :-(, pointed out by
-+ Markus F.X.J. Oberhumer <markus.oberhumer@jk.uni-linz.ac.at>.
-+
-+Version 4.01
-+ Even faster inner loop in the DES assembler for x86 and a modification
-+ for IP/FP which is faster on x86. Both of these changes are
-+ from Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. His
-+ changes make the assembler run %40 faster on a pentium. This is just
-+ a case of getting the instruction sequence 'just right'.
-+ All credit to 'Svend' :-)
-+ Quite a few special x86 'make' targets.
-+ A libdes-l (lite) distribution.
-+
-+Version 4.00
-+ After a bit of a pause, I'll up the major version number since this
-+ is mostly a performace release. I've added x86 assembler and
-+ added more options for performance. A %28 speedup for gcc
-+ on a pentium and the assembler is a %50 speedup.
-+ MIPS CPU's, sparc and Alpha are the main CPU's with speedups.
-+ Run des_opts to work out which options should be used.
-+ DES_RISC1/DES_RISC2 use alternative inner loops which use
-+ more registers but should give speedups on any CPU that does
-+ dual issue (pentium). DES_UNROLL unrolls the inner loop,
-+ which costs in code size.
-+
-+Version 3.26
-+ I've finally removed one of the shifts in D_ENCRYPT. This
-+ meant I've changed the des_SPtrans table (spr.h), the set_key()
-+ function and some things in des_enc.c. This has definitly
-+ made things faster :-). I've known about this one for some
-+ time but I've been too lazy to follow it up :-).
-+ Noticed that in the D_ENCRYPT() macro, we can just do L^=(..)^(..)^..
-+ instead of L^=((..)|(..)|(..).. This should save a register at
-+ least.
-+ Assember for x86. The file to replace is des_enc.c, which is replaced
-+ by one of the assembler files found in asm. Look at des/asm/readme
-+ for more info.
-+
-+ /* Modification to fcrypt so it can be compiled to support
-+ HPUX 10.x's long password format, define -DLONGCRYPT to use this.
-+ Thanks to Jens Kupferschmidt <bt1cu@hpboot.rz.uni-leipzig.de>. */
-+
-+ SIGWINCH case put in des_read_passwd() so the function does not
-+ 'exit' if this function is recieved.
-+
-+Version 3.25 17/07/96
-+ Modified read_pwd.c so that stdin can be read if not a tty.
-+ Thanks to Jeff Barber <jeffb@issl.atl.hp.com> for the patches.
-+ des_init_random_number_generator() shortened due to VMS linker
-+ limits.
-+ Added RSA's DESX cbc mode. It is a form of cbc encryption, with 2
-+ 8 byte quantites xored before and after encryption.
-+ des_xcbc_encryption() - the name is funny to preserve the des_
-+ prefix on all functions.
-+
-+Version 3.24 20/04/96
-+ The DES_PTR macro option checked and used by SSLeay configuration
-+
-+Version 3.23 11/04/96
-+ Added DES_LONG. If defined to 'unsigned int' on the DEC Alpha,
-+ it gives a %20 speedup :-)
-+ Fixed the problem with des.pl under perl5. The patches were
-+ sent by Ed Kubaitis (ejk@uiuc.edu).
-+ if fcrypt.c, changed values to handle illegal salt values the way
-+ normal crypt() implementations do. Some programs apparently use
-+ them :-(. The patch was sent by Bjorn Gronvall <bg@sics.se>
-+
-+Version 3.22 29/11/95
-+ Bug in des(1), an error with the uuencoding stuff when the
-+ 'data' is small, thanks to Geoff Keating <keagchon@mehta.anu.edu.au>
-+ for the patch.
-+
-+Version 3.21 22/11/95
-+ After some emailing back and forth with
-+ Colin Plumb <colin@nyx10.cs.du.edu>, I've tweaked a few things
-+ and in a future version I will probably put in some of the
-+ optimisation he suggested for use with the DES_USE_PTR option.
-+ Extra routines from Mark Murray <mark@grondar.za> for use in
-+ freeBSD. They mostly involve random number generation for use
-+ with kerberos. They involve evil machine specific system calls
-+ etc so I would normally suggest pushing this stuff into the
-+ application and/or using RAND_seed()/RAND_bytes() if you are
-+ using this DES library as part of SSLeay.
-+ Redone the read_pw() function so that it is cleaner and
-+ supports termios, thanks to Sameer Parekh <sameer@c2.org>
-+ for the initial patches for this.
-+ Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been
-+ done just to make things more consistent.
-+ I have also now added triple DES versions of cfb and ofb.
-+
-+Version 3.20
-+ Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com,
-+ my des_random_seed() function was only copying 4 bytes of the
-+ passed seed into the init structure. It is now fixed to copy 8.
-+ My own suggestion is to used something like MD5 :-)
-+
-+Version 3.19
-+ While looking at my code one day, I though, why do I keep on
-+ calling des_encrypt(in,out,ks,enc) when every function that
-+ calls it has in and out the same. So I dropped the 'out'
-+ parameter, people should not be using this function.
-+
-+Version 3.18 30/08/95
-+ Fixed a few bit with the distribution and the filenames.
-+ 3.17 had been munged via a move to DOS and back again.
-+ NO CODE CHANGES
-+
-+Version 3.17 14/07/95
-+ Fixed ede3 cbc which I had broken in 3.16. I have also
-+ removed some unneeded variables in 7-8 of the routines.
-+
-+Version 3.16 26/06/95
-+ Added des_encrypt2() which does not use IP/FP, used by triple
-+ des routines. Tweaked things a bit elsewhere. %13 speedup on
-+ sparc and %6 on a R4400 for ede3 cbc mode.
-+
-+Version 3.15 06/06/95
-+ Added des_ncbc_encrypt(), it is des_cbc mode except that it is
-+ 'normal' and copies the new iv value back over the top of the
-+ passed parameter.
-+ CHANGED des_ede3_cbc_encrypt() so that it too now overwrites
-+ the iv. THIS WILL BREAK EXISTING CODE, but since this function
-+ only new, I feel I can change it, not so with des_cbc_encrypt :-(.
-+ I need to update the documentation.
-+
-+Version 3.14 31/05/95
-+ New release upon the world, as part of my SSL implementation.
-+ New copyright and usage stuff. Basically free for all to use
-+ as long as you say it came from me :-)
-+
-+Version 3.13 31/05/95
-+ A fix in speed.c, if HZ is not defined, I set it to 100.0
-+ which is reasonable for most unixes except SunOS 4.x.
-+ I now have a #ifdef sun but timing for SunOS 4.x looked very
-+ good :-(. At my last job where I used SunOS 4.x, it was
-+ defined to be 60.0 (look at the old INSTALL documentation), at
-+ the last release had it changed to 100.0 since I now work with
-+ Solaris2 and SVR4 boxes.
-+ Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this
-+ one out.
-+
-+Version 3.12 08/05/95
-+ As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>,
-+ my D_ENCRYPT macro in crypt() had an un-necessary variable.
-+ It has been removed.
-+
-+Version 3.11 03/05/95
-+ Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys
-+ and one iv. It is a standard and I needed it for my SSL code.
-+ It makes more sense to use this for triple DES than
-+ 3cbc_encrypt(). I have also added (or should I say tested :-)
-+ cfb64_encrypt() which is cfb64 but it will encrypt a partial
-+ number of bytes - 3 bytes in 3 bytes out. Again this is for
-+ my SSL library, as a form of encryption to use with SSL
-+ telnet.
-+
-+Version 3.10 22/03/95
-+ Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls
-+ to cbc3_encrypt, the 2 iv values that were being returned to
-+ be used in the next call were reversed :-(.
-+ Many thanks to Bill Wade <wade@Stoner.COM> for pointing out
-+ this error.
-+
-+Version 3.09 01/02/95
-+ Fixed des_random_key to far more random, it was rather feeble
-+ with regards to picking the initial seed. The problem was
-+ pointed out by Olaf Kirch <okir@monad.swb.de>.
-+
-+Version 3.08 14/12/94
-+ Added Makefile.PL so libdes can be built into perl5.
-+ Changed des_locl.h so RAND is always defined.
-+
-+Version 3.07 05/12/94
-+ Added GNUmake and stuff so the library can be build with
-+ glibc.
-+
-+Version 3.06 30/08/94
-+ Added rpc_enc.c which contains _des_crypt. This is for use in
-+ secure_rpc v 4.0
-+ Finally fixed the cfb_enc problems.
-+ Fixed a few parameter parsing bugs in des (-3 and -b), thanks
-+ to Rob McMillan <R.McMillan@its.gu.edu.au>
-+
-+Version 3.05 21/04/94
-+ for unsigned long l; gcc does not produce ((l>>34) == 0)
-+ This causes bugs in cfb_enc.
-+ Thanks to Hadmut Danisch <danisch@ira.uka.de>
-+
-+Version 3.04 20/04/94
-+ Added a version number to des.c and libdes.a
-+
-+Version 3.03 12/01/94
-+ Fixed a bug in non zero iv in 3cbc_enc.
-+
-+Version 3.02 29/10/93
-+ I now work in a place where there are 6+ architectures and 14+
-+ OS versions :-).
-+ Fixed TERMIO definition so the most sys V boxes will work :-)
-+
-+Release upon comp.sources.misc
-+Version 3.01 08/10/93
-+ Added des_3cbc_encrypt()
-+
-+Version 3.00 07/10/93
-+ Fixed up documentation.
-+ quad_cksum definitely compatible with MIT's now.
-+
-+Version 2.30 24/08/93
-+ Triple DES now defaults to triple cbc but can do triple ecb
-+ with the -b flag.
-+ Fixed some MSDOS uuen/uudecoding problems, thanks to
-+ Added prototypes.
-+
-+Version 2.22 29/06/93
-+ Fixed a bug in des_is_weak_key() which stopped it working :-(
-+ thanks to engineering@MorningStar.Com.
-+
-+Version 2.21 03/06/93
-+ des(1) with no arguments gives quite a bit of help.
-+ Added -c (generate ckecksum) flag to des(1).
-+ Added -3 (triple DES) flag to des(1).
-+ Added cfb and ofb routines to the library.
-+
-+Version 2.20 11/03/93
-+ Added -u (uuencode) flag to des(1).
-+ I have been playing with byte order in quad_cksum to make it
-+ compatible with MIT's version. All I can say is avid this
-+ function if possible since MIT's output is endian dependent.
-+
-+Version 2.12 14/10/92
-+ Added MSDOS specific macro in ecb_encrypt which gives a %70
-+ speed up when the code is compiled with turbo C.
-+
-+Version 2.11 12/10/92
-+ Speedup in set_key (recoding of PC-1)
-+ I now do it in 47 simple operations, down from 60.
-+ Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov)
-+ for motivating me to look for a faster system :-)
-+ The speedup is probably less that 1% but it is still 13
-+ instructions less :-).
-+
-+Version 2.10 06/10/92
-+ The code now works on the 64bit ETA10 and CRAY without modifications or
-+ #defines. I believe the code should work on any machine that
-+ defines long, int or short to be 8 bytes long.
-+ Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu)
-+ for helping me fix the code to run on 64bit machines (he had
-+ access to an ETA10).
-+ Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov>
-+ for testing the routines on a CRAY.
-+ read_password.c has been renamed to read_passwd.c
-+ string_to_key.c has been renamed to string2key.c
-+
-+Version 2.00 14/09/92
-+ Made mods so that the library should work on 64bit CPU's.
-+ Removed all my uchar and ulong defs. To many different
-+ versions of unix define them in their header files in too many
-+ different combinations :-)
-+ IRIX - Sillicon Graphics mods (mostly in read_password.c).
-+ Thanks to Andrew Daviel (advax@erich.triumf.ca)
-+
-+Version 1.99 26/08/92
-+ Fixed a bug or 2 in enc_read.c
-+ Fixed a bug in enc_write.c
-+ Fixed a pseudo bug in fcrypt.c (very obscure).
-+
-+Version 1.98 31/07/92
-+ Support for the ETA10. This is a strange machine that defines
-+ longs and ints as 8 bytes and shorts as 4 bytes.
-+ Since I do evil things with long * that assume that they are 4
-+ bytes. Look in the Makefile for the option to compile for
-+ this machine. quad_cksum appears to have problems but I
-+ will don't have the time to fix it right now, and this is not
-+ a function that uses DES and so will not effect the main uses
-+ of the library.
-+
-+Version 1.97 20/05/92 eay
-+ Fixed the Imakefile and made some changes to des.h to fix some
-+ problems when building this package with Kerberos v 4.
-+
-+Version 1.96 18/05/92 eay
-+ Fixed a small bug in string_to_key() where problems could
-+ occur if des_check_key was set to true and the string
-+ generated a weak key.
-+
-+Patch2 posted to comp.sources.misc
-+Version 1.95 13/05/92 eay
-+ Added an alternative version of the D_ENCRYPT macro in
-+ ecb_encrypt and fcrypt. Depending on the compiler, one version or the
-+ other will be faster. This was inspired by
-+ Dana How <how@isl.stanford.edu>, and her pointers about doing the
-+ *(ulong *)((uchar *)ptr+(value&0xfc))
-+ vs
-+ ptr[value&0x3f]
-+ to stop the C compiler doing a <<2 to convert the long array index.
-+
-+Version 1.94 05/05/92 eay
-+ Fixed an incompatibility between my string_to_key and the MIT
-+ version. When the key is longer than 8 chars, I was wrapping
-+ with a different method. To use the old version, define
-+ OLD_STR_TO_KEY in the makefile. Thanks to
-+ viktor@newsu.shearson.com (Viktor Dukhovni).
-+
-+Version 1.93 28/04/92 eay
-+ Fixed the VMS mods so that echo is now turned off in
-+ read_password. Thanks again to brennan@coco.cchs.su.oz.AU.
-+ MSDOS support added. The routines can be compiled with
-+ Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined.
-+
-+Patch1 posted to comp.sources.misc
-+Version 1.92 13/04/92 eay
-+ Changed D_ENCRYPT so that the rotation of R occurs outside of
-+ the loop. This required rotating all the longs in sp.h (now
-+ called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM>
-+ speed.c has been changed so it will work without SIGALRM. If
-+ times(3) is not present it will try to use ftime() instead.
-+
-+Version 1.91 08/04/92 eay
-+ Added -E/-D options to des(1) so it can use string_to_key.
-+ Added SVR4 mods suggested by witr@rwwa.COM
-+ Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If
-+ anyone knows how to turn of tty echo in VMS please tell me or
-+ implement it yourself :-).
-+ Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS
-+ does not like IN/OUT being used.
-+
-+Libdes posted to comp.sources.misc
-+Version 1.9 24/03/92 eay
-+ Now contains a fast small crypt replacement.
-+ Added des(1) command.
-+ Added des_rw_mode so people can use cbc encryption with
-+ enc_read and enc_write.
-+
-+Version 1.8 15/10/91 eay
-+ Bug in cbc_cksum.
-+ Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this
-+ one out.
-+
-+Version 1.7 24/09/91 eay
-+ Fixed set_key :-)
-+ set_key is 4 times faster and takes less space.
-+ There are a few minor changes that could be made.
-+
-+Version 1.6 19/09/1991 eay
-+ Finally go IP and FP finished.
-+ Now I need to fix set_key.
-+ This version is quite a bit faster that 1.51
-+
-+Version 1.52 15/06/1991 eay
-+ 20% speedup in ecb_encrypt by changing the E bit selection
-+ to use 2 32bit words. This also required modification of the
-+ sp table. There is still a way to speedup the IP and IP-1
-+ (hints from outer@sq.com) still working on this one :-(.
-+
-+Version 1.51 07/06/1991 eay
-+ Faster des_encrypt by loop unrolling
-+ Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu)
-+
-+Version 1.50 28/05/1991 eay
-+ Optimised the code a bit more for the sparc. I have improved the
-+ speed of the inner des_encrypt by speeding up the initial and
-+ final permutations.
-+
-+Version 1.40 23/10/1990 eay
-+ Fixed des_random_key, it did not produce a random key :-(
-+
-+Version 1.30 2/10/1990 eay
-+ Have made des_quad_cksum the same as MIT's, the full package
-+ should be compatible with MIT's
-+ Have tested on a DECstation 3100
-+ Still need to fix des_set_key (make it faster).
-+ Does des_cbc_encrypts at 70.5k/sec on a 3100.
-+
-+Version 1.20 18/09/1990 eay
-+ Fixed byte order dependencies.
-+ Fixed (I hope) all the word alignment problems.
-+ Speedup in des_ecb_encrypt.
-+
-+Version 1.10 11/09/1990 eay
-+ Added des_enc_read and des_enc_write.
-+ Still need to fix des_quad_cksum.
-+ Still need to document des_enc_read and des_enc_write.
-+
-+Version 1.00 27/08/1990 eay

-+First up, let me say I don't like writing in assembler. It is not portable,
-+dependant on the particular CPU architecture release and is generally a pig
-+to debug and get right. Having said that, the x86 architecture is probably
-+the most important for speed due to number of boxes and since
-+it appears to be the worst architecture to to get
-+good C compilers for. So due to this, I have lowered myself to do
-+assembler for the inner DES routines in libdes :-).
-+
-+The file to implement in assembler is des_enc.c. Replace the following
-+4 functions
-+des_encrypt(DES_LONG data[2],des_key_schedule ks, int encrypt);
-+des_encrypt2(DES_LONG data[2],des_key_schedule ks, int encrypt);
-+des_encrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3);
-+des_decrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3);
-+
-+They encrypt/decrypt the 64 bits held in 'data' using
-+the 'ks' key schedules. The only difference between the 4 functions is that
-+des_encrypt2() does not perform IP() or FP() on the data (this is an
-+optimization for when doing triple DES and des_encrypt3() and des_decrypt3()
-+perform triple des. The triple DES routines are in here because it does
-+make a big difference to have them located near the des_encrypt2 function
-+at link time..
-+
-+Now as we all know, there are lots of different operating systems running on
-+x86 boxes, and unfortunately they normally try to make sure their assembler
-+formating is not the same as the other peoples.
-+The 4 main formats I know of are
-+Microsoft Windows 95/Windows NT
-+Elf Includes Linux and FreeBSD(?).
-+a.out The older Linux.
-+Solaris Same as Elf but different comments :-(.
-+
-+Now I was not overly keen to write 4 different copies of the same code,
-+so I wrote a few perl routines to output the correct assembler, given
-+a target assembler type. This code is ugly and is just a hack.
-+The libraries are x86unix.pl and x86ms.pl.
-+des586.pl, des686.pl and des-som[23].pl are the programs to actually
-+generate the assembler.
-+
-+So to generate elf assembler
-+perl des-som3.pl elf >dx86-elf.s
-+For Windows 95/NT
-+perl des-som2.pl win32 >win32.asm
-+
-+[ update 4 Jan 1996 ]
-+I have added another way to do things.
-+perl des-som3.pl cpp >dx86-cpp.s
-+generates a file that will be included by dx86unix.cpp when it is compiled.
-+To build for elf, a.out, solaris, bsdi etc,
-+cc -E -DELF asm/dx86unix.cpp | as -o asm/dx86-elf.o
-+cc -E -DSOL asm/dx86unix.cpp | as -o asm/dx86-sol.o
-+cc -E -DOUT asm/dx86unix.cpp | as -o asm/dx86-out.o
-+cc -E -DBSDI asm/dx86unix.cpp | as -o asm/dx86bsdi.o
-+This was done to cut down the number of files in the distribution.
-+
-+Now the ugly part. I acquired my copy of Intels
-+"Optimization's For Intel's 32-Bit Processors" and found a few interesting
-+things. First, the aim of the exersize is to 'extract' one byte at a time
-+from a word and do an array lookup. This involves getting the byte from
-+the 4 locations in the word and moving it to a new word and doing the lookup.
-+The most obvious way to do this is
-+xor eax, eax # clear word
-+movb al, cl # get low byte
-+xor edi DWORD PTR 0x100+des_SP[eax] # xor in word
-+movb al, ch # get next byte
-+xor edi DWORD PTR 0x300+des_SP[eax] # xor in word
-+shr ecx 16
-+which seems ok. For the pentium, this system appears to be the best.
-+One has to do instruction interleaving to keep both functional units
-+operating, but it is basically very efficient.
-+
-+Now the crunch. When a full register is used after a partial write, eg.
-+mov al, cl
-+xor edi, DWORD PTR 0x100+des_SP[eax]
-+386 - 1 cycle stall
-+486 - 1 cycle stall
-+586 - 0 cycle stall
-+686 - at least 7 cycle stall (page 22 of the above mentioned document).
-+
-+So the technique that produces the best results on a pentium, according to
-+the documentation, will produce hideous results on a pentium pro.
-+
-+To get around this, des686.pl will generate code that is not as fast on
-+a pentium, should be very good on a pentium pro.
-+mov eax, ecx # copy word
-+shr ecx, 8 # line up next byte
-+and eax, 0fch # mask byte
-+xor edi DWORD PTR 0x100+des_SP[eax] # xor in array lookup
-+mov eax, ecx # get word
-+shr ecx 8 # line up next byte
-+and eax, 0fch # mask byte
-+xor edi DWORD PTR 0x300+des_SP[eax] # xor in array lookup
-+
-+Due to the execution units in the pentium, this actually works quite well.
-+For a pentium pro it should be very good. This is the type of output
-+Visual C++ generates.
-+
-+There is a third option. instead of using
-+mov al, ch
-+which is bad on the pentium pro, one may be able to use
-+movzx eax, ch
-+which may not incur the partial write penalty. On the pentium,
-+this instruction takes 4 cycles so is not worth using but on the
-+pentium pro it appears it may be worth while. I need access to one to
-+experiment :-).
-+
-+eric (20 Oct 1996)
-+
-+22 Nov 1996 - I have asked people to run the 2 different version on pentium
-+pros and it appears that the intel documentation is wrong. The
-+mov al,bh is still faster on a pentium pro, so just use the des586.pl
-+install des686.pl
-+
-+3 Dec 1996 - I added des_encrypt3/des_decrypt3 because I have moved these
-+functions into des_enc.c because it does make a massive performance
-+difference on some boxes to have the functions code located close to
-+the des_encrypt2() function.
-+
-+9 Jan 1997 - des-som2.pl is now the correct perl script to use for
-+pentiums. It contains an inner loop from
-+Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk> which does raw ecb DES calls at
-+273,000 per second. He had a previous version at 250,000 and the best
-+I was able to get was 203,000. The content has not changed, this is all
-+due to instruction sequencing (and actual instructions choice) which is able
-+to keep both functional units of the pentium going.
-+We may have lost the ugly register usage restrictions when x86 went 32 bit
-+but for the pentium it has been replaced by evil instruction ordering tricks.
-+
-+13 Jan 1997 - des-som3.pl, more optimizations from Svend Olaf.
-+raw DES at 281,000 per second on a pentium 100.

-+The DES library.
-+
-+Please note that this library was originally written to operate with
-+eBones, a version of Kerberos that had had encryption removed when it left
-+the USA and then put back in. As such there are some routines that I will
-+advise not using but they are still in the library for historical reasons.
-+For all calls that have an 'input' and 'output' variables, they can be the
-+same.
-+
-+This library requires the inclusion of 'des.h'.
-+
-+All of the encryption functions take what is called a des_key_schedule as an
-+argument. A des_key_schedule is an expanded form of the des key.
-+A des_key is 8 bytes of odd parity, the type used to hold the key is a
-+des_cblock. A des_cblock is an array of 8 bytes, often in this library
-+description I will refer to input bytes when the function specifies
-+des_cblock's as input or output, this just means that the variable should
-+be a multiple of 8 bytes.
-+
-+The define DES_ENCRYPT is passed to specify encryption, DES_DECRYPT to
-+specify decryption. The functions and global variable are as follows:
-+
-+int des_check_key;
-+ DES keys are supposed to be odd parity. If this variable is set to
-+ a non-zero value, des_set_key() will check that the key has odd
-+ parity and is not one of the known weak DES keys. By default this
-+ variable is turned off;
-+
-+void des_set_odd_parity(
-+des_cblock *key );
-+ This function takes a DES key (8 bytes) and sets the parity to odd.
-+
-+int des_is_weak_key(
-+des_cblock *key );
-+ This function returns a non-zero value if the DES key passed is a
-+ weak, DES key. If it is a weak key, don't use it, try a different
-+ one. If you are using 'random' keys, the chances of hitting a weak
-+ key are 1/2^52 so it is probably not worth checking for them.
-+
-+int des_set_key(
-+des_cblock *key,
-+des_key_schedule schedule);
-+ Des_set_key converts an 8 byte DES key into a des_key_schedule.
-+ A des_key_schedule is an expanded form of the key which is used to
-+ perform actual encryption. It can be regenerated from the DES key
-+ so it only needs to be kept when encryption or decryption is about
-+ to occur. Don't save or pass around des_key_schedule's since they
-+ are CPU architecture dependent, DES keys are not. If des_check_key
-+ is non zero, zero is returned if the key has the wrong parity or
-+ the key is a weak key, else 1 is returned.
-+
-+int des_key_sched(
-+des_cblock *key,
-+des_key_schedule schedule);
-+ An alternative name for des_set_key().
-+
-+int des_rw_mode; /* defaults to DES_PCBC_MODE */
-+ This flag holds either DES_CBC_MODE or DES_PCBC_MODE (default).
-+ This specifies the function to use in the enc_read() and enc_write()
-+ functions.
-+
-+void des_encrypt(
-+unsigned long *data,
-+des_key_schedule ks,
-+int enc);
-+ This is the DES encryption function that gets called by just about
-+ every other DES routine in the library. You should not use this
-+ function except to implement 'modes' of DES. I say this because the
-+ functions that call this routine do the conversion from 'char *' to
-+ long, and this needs to be done to make sure 'non-aligned' memory
-+ access do not occur. The characters are loaded 'little endian',
-+ have a look at my source code for more details on how I use this
-+ function.
-+ Data is a pointer to 2 unsigned long's and ks is the
-+ des_key_schedule to use. enc, is non zero specifies encryption,
-+ zero if decryption.
-+
-+void des_encrypt2(
-+unsigned long *data,
-+des_key_schedule ks,
-+int enc);
-+ This functions is the same as des_encrypt() except that the DES
-+ initial permutation (IP) and final permutation (FP) have been left
-+ out. As for des_encrypt(), you should not use this function.
-+ It is used by the routines in my library that implement triple DES.
-+ IP() des_encrypt2() des_encrypt2() des_encrypt2() FP() is the same
-+ as des_encrypt() des_encrypt() des_encrypt() except faster :-).
-+
-+void des_ecb_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+des_key_schedule ks,
-+int enc);
-+ This is the basic Electronic Code Book form of DES, the most basic
-+ form. Input is encrypted into output using the key represented by
-+ ks. If enc is non zero (DES_ENCRYPT), encryption occurs, otherwise
-+ decryption occurs. Input is 8 bytes long and output is 8 bytes.
-+ (the des_cblock structure is 8 chars).
-+
-+void des_ecb3_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+des_key_schedule ks1,
-+des_key_schedule ks2,
-+des_key_schedule ks3,
-+int enc);
-+ This is the 3 key EDE mode of ECB DES. What this means is that
-+ the 8 bytes of input is encrypted with ks1, decrypted with ks2 and
-+ then encrypted again with ks3, before being put into output;
-+ C=E(ks3,D(ks2,E(ks1,M))). There is a macro, des_ecb2_encrypt()
-+ that only takes 2 des_key_schedules that implements,
-+ C=E(ks1,D(ks2,E(ks1,M))) in that the final encrypt is done with ks1.
-+
-+void des_cbc_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+des_key_schedule ks,
-+des_cblock *ivec,
-+int enc);
-+ This routine implements DES in Cipher Block Chaining mode.
-+ Input, which should be a multiple of 8 bytes is encrypted
-+ (or decrypted) to output which will also be a multiple of 8 bytes.
-+ The number of bytes is in length (and from what I've said above,
-+ should be a multiple of 8). If length is not a multiple of 8, I'm
-+ not being held responsible :-). ivec is the initialisation vector.
-+ This function does not modify this variable. To correctly implement
-+ cbc mode, you need to do one of 2 things; copy the last 8 bytes of
-+ cipher text for use as the next ivec in your application,
-+ or use des_ncbc_encrypt().
-+ Only this routine has this problem with updating the ivec, all
-+ other routines that are implementing cbc mode update ivec.
-+
-+void des_ncbc_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+des_key_schedule sk,
-+des_cblock *ivec,
-+int enc);
-+ For historical reasons, des_cbc_encrypt() did not update the
-+ ivec with the value requires so that subsequent calls to
-+ des_cbc_encrypt() would 'chain'. This was needed so that the same
-+ 'length' values would not need to be used when decrypting.
-+ des_ncbc_encrypt() does the right thing. It is the same as
-+ des_cbc_encrypt accept that ivec is updates with the correct value
-+ to pass in subsequent calls to des_ncbc_encrypt(). I advise using
-+ des_ncbc_encrypt() instead of des_cbc_encrypt();
-+
-+void des_xcbc_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+des_key_schedule sk,
-+des_cblock *ivec,
-+des_cblock *inw,
-+des_cblock *outw,
-+int enc);
-+ This is RSA's DESX mode of DES. It uses inw and outw to
-+ 'whiten' the encryption. inw and outw are secret (unlike the iv)
-+ and are as such, part of the key. So the key is sort of 24 bytes.
-+ This is much better than cbc des.
-+
-+void des_3cbc_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+des_key_schedule sk1,
-+des_key_schedule sk2,
-+des_cblock *ivec1,
-+des_cblock *ivec2,
-+int enc);
-+ This function is flawed, do not use it. I have left it in the
-+ library because it is used in my des(1) program and will function
-+ correctly when used by des(1). If I removed the function, people
-+ could end up unable to decrypt files.
-+ This routine implements outer triple cbc encryption using 2 ks and
-+ 2 ivec's. Use des_ede2_cbc_encrypt() instead.
-+
-+void des_ede3_cbc_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+des_key_schedule ks1,
-+des_key_schedule ks2,
-+des_key_schedule ks3,
-+des_cblock *ivec,
-+int enc);
-+ This function implements inner triple CBC DES encryption with 3
-+ keys. What this means is that each 'DES' operation
-+ inside the cbc mode is really an C=E(ks3,D(ks2,E(ks1,M))).
-+ Again, this is cbc mode so an ivec is requires.
-+ This mode is used by SSL.
-+ There is also a des_ede2_cbc_encrypt() that only uses 2
-+ des_key_schedule's, the first being reused for the final
-+ encryption. C=E(ks1,D(ks2,E(ks1,M))). This form of triple DES
-+ is used by the RSAref library.
-+
-+void des_pcbc_encrypt(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+des_key_schedule ks,
-+des_cblock *ivec,
-+int enc);
-+ This is Propagating Cipher Block Chaining mode of DES. It is used
-+ by Kerberos v4. It's parameters are the same as des_ncbc_encrypt().
-+
-+void des_cfb_encrypt(
-+unsigned char *in,
-+unsigned char *out,
-+int numbits,
-+long length,
-+des_key_schedule ks,
-+des_cblock *ivec,
-+int enc);
-+ Cipher Feedback Back mode of DES. This implementation 'feeds back'
-+ in numbit blocks. The input (and output) is in multiples of numbits
-+ bits. numbits should to be a multiple of 8 bits. Length is the
-+ number of bytes input. If numbits is not a multiple of 8 bits,
-+ the extra bits in the bytes will be considered padding. So if
-+ numbits is 12, for each 2 input bytes, the 4 high bits of the
-+ second byte will be ignored. So to encode 72 bits when using
-+ a numbits of 12 take 12 bytes. To encode 72 bits when using
-+ numbits of 9 will take 16 bytes. To encode 80 bits when using
-+ numbits of 16 will take 10 bytes. etc, etc. This padding will
-+ apply to both input and output.
-+
-+
-+void des_cfb64_encrypt(
-+unsigned char *in,
-+unsigned char *out,
-+long length,
-+des_key_schedule ks,
-+des_cblock *ivec,
-+int *num,
-+int enc);
-+ This is one of the more useful functions in this DES library, it
-+ implements CFB mode of DES with 64bit feedback. Why is this
-+ useful you ask? Because this routine will allow you to encrypt an
-+ arbitrary number of bytes, no 8 byte padding. Each call to this
-+ routine will encrypt the input bytes to output and then update ivec
-+ and num. num contains 'how far' we are though ivec. If this does
-+ not make much sense, read more about cfb mode of DES :-).
-+
-+void des_ede3_cfb64_encrypt(
-+unsigned char *in,
-+unsigned char *out,
-+long length,
-+des_key_schedule ks1,
-+des_key_schedule ks2,
-+des_key_schedule ks3,
-+des_cblock *ivec,
-+int *num,
-+int enc);
-+ Same as des_cfb64_encrypt() accept that the DES operation is
-+ triple DES. As usual, there is a macro for
-+ des_ede2_cfb64_encrypt() which reuses ks1.
-+
-+void des_ofb_encrypt(
-+unsigned char *in,
-+unsigned char *out,
-+int numbits,
-+long length,
-+des_key_schedule ks,
-+des_cblock *ivec);
-+ This is a implementation of Output Feed Back mode of DES. It is
-+ the same as des_cfb_encrypt() in that numbits is the size of the
-+ units dealt with during input and output (in bits).
-+
-+void des_ofb64_encrypt(
-+unsigned char *in,
-+unsigned char *out,
-+long length,
-+des_key_schedule ks,
-+des_cblock *ivec,
-+int *num);
-+ The same as des_cfb64_encrypt() except that it is Output Feed Back
-+ mode.
-+
-+void des_ede3_ofb64_encrypt(
-+unsigned char *in,
-+unsigned char *out,
-+long length,
-+des_key_schedule ks1,
-+des_key_schedule ks2,
-+des_key_schedule ks3,
-+des_cblock *ivec,
-+int *num);
-+ Same as des_ofb64_encrypt() accept that the DES operation is
-+ triple DES. As usual, there is a macro for
-+ des_ede2_ofb64_encrypt() which reuses ks1.
-+
-+int des_read_pw_string(
-+char *buf,
-+int length,
-+char *prompt,
-+int verify);
-+ This routine is used to get a password from the terminal with echo
-+ turned off. Buf is where the string will end up and length is the
-+ size of buf. Prompt is a string presented to the 'user' and if
-+ verify is set, the key is asked for twice and unless the 2 copies
-+ match, an error is returned. A return code of -1 indicates a
-+ system error, 1 failure due to use interaction, and 0 is success.
-+
-+unsigned long des_cbc_cksum(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+des_key_schedule ks,
-+des_cblock *ivec);
-+ This function produces an 8 byte checksum from input that it puts in
-+ output and returns the last 4 bytes as a long. The checksum is
-+ generated via cbc mode of DES in which only the last 8 byes are
-+ kept. I would recommend not using this function but instead using
-+ the EVP_Digest routines, or at least using MD5 or SHA. This
-+ function is used by Kerberos v4 so that is why it stays in the
-+ library.
-+
-+char *des_fcrypt(
-+const char *buf,
-+const char *salt
-+char *ret);
-+ This is my fast version of the unix crypt(3) function. This version
-+ takes only a small amount of space relative to other fast
-+ crypt() implementations. This is different to the normal crypt
-+ in that the third parameter is the buffer that the return value
-+ is written into. It needs to be at least 14 bytes long. This
-+ function is thread safe, unlike the normal crypt.
-+
-+char *crypt(
-+const char *buf,
-+const char *salt);
-+ This function calls des_fcrypt() with a static array passed as the
-+ third parameter. This emulates the normal non-thread safe semantics
-+ of crypt(3).
-+
-+void des_string_to_key(
-+char *str,
-+des_cblock *key);
-+ This function takes str and converts it into a DES key. I would
-+ recommend using MD5 instead and use the first 8 bytes of output.
-+ When I wrote the first version of these routines back in 1990, MD5
-+ did not exist but I feel these routines are still sound. This
-+ routines is compatible with the one in MIT's libdes.
-+
-+void des_string_to_2keys(
-+char *str,
-+des_cblock *key1,
-+des_cblock *key2);
-+ This function takes str and converts it into 2 DES keys.
-+ I would recommend using MD5 and using the 16 bytes as the 2 keys.
-+ I have nothing against these 2 'string_to_key' routines, it's just
-+ that if you say that your encryption key is generated by using the
-+ 16 bytes of an MD5 hash, every-one knows how you generated your
-+ keys.
-+
-+int des_read_password(
-+des_cblock *key,
-+char *prompt,
-+int verify);
-+ This routine combines des_read_pw_string() with des_string_to_key().
-+
-+int des_read_2passwords(
-+des_cblock *key1,
-+des_cblock *key2,
-+char *prompt,
-+int verify);
-+ This routine combines des_read_pw_string() with des_string_to_2key().
-+
-+void des_random_seed(
-+des_cblock key);
-+ This routine sets a starting point for des_random_key().
-+
-+void des_random_key(
-+des_cblock ret);
-+ This function return a random key. Make sure to 'seed' the random
-+ number generator (with des_random_seed()) before using this function.
-+ I personally now use a MD5 based random number system.
-+
-+int des_enc_read(
-+int fd,
-+char *buf,
-+int len,
-+des_key_schedule ks,
-+des_cblock *iv);
-+ This function will write to a file descriptor the encrypted data
-+ from buf. This data will be preceded by a 4 byte 'byte count' and
-+ will be padded out to 8 bytes. The encryption is either CBC of
-+ PCBC depending on the value of des_rw_mode. If it is DES_PCBC_MODE,
-+ pcbc is used, if DES_CBC_MODE, cbc is used. The default is to use
-+ DES_PCBC_MODE.
-+
-+int des_enc_write(
-+int fd,
-+char *buf,
-+int len,
-+des_key_schedule ks,
-+des_cblock *iv);
-+ This routines read stuff written by des_enc_read() and decrypts it.
-+ I have used these routines quite a lot but I don't believe they are
-+ suitable for non-blocking io. If you are after a full
-+ authentication/encryption over networks, have a look at SSL instead.
-+
-+unsigned long des_quad_cksum(
-+des_cblock *input,
-+des_cblock *output,
-+long length,
-+int out_count,
-+des_cblock *seed);
-+ This is a function from Kerberos v4 that is not anything to do with
-+ DES but was needed. It is a cksum that is quicker to generate than
-+ des_cbc_cksum(); I personally would use MD5 routines now.
-+=====
-+Modes of DES
-+Quite a bit of the following information has been taken from
-+ AS 2805.5.2
-+ Australian Standard
-+ Electronic funds transfer - Requirements for interfaces,
-+ Part 5.2: Modes of operation for an n-bit block cipher algorithm
-+ Appendix A
-+
-+There are several different modes in which DES can be used, they are
-+as follows.
-+
-+Electronic Codebook Mode (ECB) (des_ecb_encrypt())
-+- 64 bits are enciphered at a time.
-+- The order of the blocks can be rearranged without detection.
-+- The same plaintext block always produces the same ciphertext block
-+ (for the same key) making it vulnerable to a 'dictionary attack'.
-+- An error will only affect one ciphertext block.
-+
-+Cipher Block Chaining Mode (CBC) (des_cbc_encrypt())
-+- a multiple of 64 bits are enciphered at a time.
-+- The CBC mode produces the same ciphertext whenever the same
-+ plaintext is encrypted using the same key and starting variable.
-+- The chaining operation makes the ciphertext blocks dependent on the
-+ current and all preceding plaintext blocks and therefore blocks can not
-+ be rearranged.
-+- The use of different starting variables prevents the same plaintext
-+ enciphering to the same ciphertext.
-+- An error will affect the current and the following ciphertext blocks.
-+
-+Cipher Feedback Mode (CFB) (des_cfb_encrypt())
-+- a number of bits (j) <= 64 are enciphered at a time.
-+- The CFB mode produces the same ciphertext whenever the same
-+ plaintext is encrypted using the same key and starting variable.
-+- The chaining operation makes the ciphertext variables dependent on the
-+ current and all preceding variables and therefore j-bit variables are
-+ chained together and can not be rearranged.
-+- The use of different starting variables prevents the same plaintext
-+ enciphering to the same ciphertext.
-+- The strength of the CFB mode depends on the size of k (maximal if
-+ j == k). In my implementation this is always the case.
-+- Selection of a small value for j will require more cycles through
-+ the encipherment algorithm per unit of plaintext and thus cause
-+ greater processing overheads.
-+- Only multiples of j bits can be enciphered.
-+- An error will affect the current and the following ciphertext variables.
-+
-+Output Feedback Mode (OFB) (des_ofb_encrypt())
-+- a number of bits (j) <= 64 are enciphered at a time.
-+- The OFB mode produces the same ciphertext whenever the same
-+ plaintext enciphered using the same key and starting variable. More
-+ over, in the OFB mode the same key stream is produced when the same
-+ key and start variable are used. Consequently, for security reasons
-+ a specific start variable should be used only once for a given key.
-+- The absence of chaining makes the OFB more vulnerable to specific attacks.
-+- The use of different start variables values prevents the same
-+ plaintext enciphering to the same ciphertext, by producing different
-+ key streams.
-+- Selection of a small value for j will require more cycles through
-+ the encipherment algorithm per unit of plaintext and thus cause
-+ greater processing overheads.
-+- Only multiples of j bits can be enciphered.
-+- OFB mode of operation does not extend ciphertext errors in the
-+ resultant plaintext output. Every bit error in the ciphertext causes
-+ only one bit to be in error in the deciphered plaintext.
-+- OFB mode is not self-synchronising. If the two operation of
-+ encipherment and decipherment get out of synchronism, the system needs
-+ to be re-initialised.
-+- Each re-initialisation should use a value of the start variable
-+ different from the start variable values used before with the same
-+ key. The reason for this is that an identical bit stream would be
-+ produced each time from the same parameters. This would be
-+ susceptible to a ' known plaintext' attack.
-+
-+Triple ECB Mode (des_ecb3_encrypt())
-+- Encrypt with key1, decrypt with key2 and encrypt with key3 again.
-+- As for ECB encryption but increases the key length to 168 bits.
-+ There are theoretic attacks that can be used that make the effective
-+ key length 112 bits, but this attack also requires 2^56 blocks of
-+ memory, not very likely, even for the NSA.
-+- If both keys are the same it is equivalent to encrypting once with
-+ just one key.
-+- If the first and last key are the same, the key length is 112 bits.
-+ There are attacks that could reduce the key space to 55 bit's but it
-+ requires 2^56 blocks of memory.
-+- If all 3 keys are the same, this is effectively the same as normal
-+ ecb mode.
-+
-+Triple CBC Mode (des_ede3_cbc_encrypt())
-+- Encrypt with key1, decrypt with key2 and then encrypt with key3.
-+- As for CBC encryption but increases the key length to 168 bits with
-+ the same restrictions as for triple ecb mode.

-+ Notes beyond the 1.93a appnote.txt:
-+
-+ 1. Distance pointers never point before the beginning of the output
-+ stream.
-+ 2. Distance pointers can point back across blocks, up to 32k away.
-+ 3. There is an implied maximum of 7 bits for the bit length table and
-+ 15 bits for the actual data.
-+ 4. If only one code exists, then it is encoded using one bit. (Zero
-+ would be more efficient, but perhaps a little confusing.) If two
-+ codes exist, they are coded using one bit each (0 and 1).
-+ 5. There is no way of sending zero distance codes--a dummy must be
-+ sent if there are none. (History: a pre 2.0 version of PKZIP would
-+ store blocks with no distance codes, but this was discovered to be
-+ too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
-+ zero distance codes, which is sent as one code of zero bits in
-+ length.
-+ 6. There are up to 286 literal/length codes. Code 256 represents the
-+ end-of-block. Note however that the static length tree defines
-+ 288 codes just to fill out the Huffman codes. Codes 286 and 287
-+ cannot be used though, since there is no length base or extra bits
-+ defined for them. Similarily, there are up to 30 distance codes.
-+ However, static trees define 32 codes (all 5 bits) to fill out the
-+ Huffman codes, but the last two had better not show up in the data.
-+ 7. Unzip can check dynamic Huffman blocks for complete code sets.
-+ The exception is that a single code would not be complete (see #4).
-+ 8. The five bits following the block type is really the number of
-+ literal codes sent minus 257.
-+ 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-+ (1+6+6). Therefore, to output three times the length, you output
-+ three codes (1+1+1), whereas to output four times the same length,
-+ you only need two codes (1+3). Hmm.
-+ 10. In the tree reconstruction algorithm, Code = Code + Increment
-+ only if BitLength(i) is not zero. (Pretty obvious.)
-+ 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
-+ 12. Note: length code 284 can represent 227-258, but length code 285
-+ really is 258. The last length deserves its own, short code
-+ since it gets used a lot in very redundant files. The length
-+ 258 is special since 258 - 3 (the min match length) is 255.
-+ 13. The literal/length and distance code bit lengths are read as a
-+ single stream of lengths. It is possible (and advantageous) for
-+ a repeat code (16, 17, or 18) to go across the boundary between
-+ the two sets of lengths.

-+ Huffman code decoding is performed using a multi-level table lookup.
-+ The fastest way to decode is to simply build a lookup table whose
-+ size is determined by the longest code. However, the time it takes
-+ to build this table can also be a factor if the data being decoded
-+ is not very long. The most common codes are necessarily the
-+ shortest codes, so those codes dominate the decoding time, and hence
-+ the speed. The idea is you can have a shorter table that decodes the
-+ shorter, more probable codes, and then point to subsidiary tables for
-+ the longer codes. The time it costs to decode the longer codes is
-+ then traded against the time it takes to make longer tables.
-+
-+ This results of this trade are in the variables lbits and dbits
-+ below. lbits is the number of bits the first level table for literal/
-+ length codes can decode in one step, and dbits is the same thing for
-+ the distance codes. Subsequent tables are also less than or equal to
-+ those sizes. These values may be adjusted either when all of the
-+ codes are shorter than that, in which case the longest code length in
-+ bits is used, or when the shortest code is *longer* than the requested
-+ table size, in which case the length of the shortest code in bits is
-+ used.
-+
-+ There are two different values for the two tables, since they code a
-+ different number of possibilities each. The literal/length table
-+ codes 286 possible values, or in a flat code, a little over eight
-+ bits. The distance table codes 30 possible values, or a little less
-+ than five bits, flat. The optimum values for speed end up being
-+ about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-+ The optimum values may differ though from machine to machine, and
-+ possibly even between compilers. Your mileage may vary.

-+ * Fix for 2.6.18+ only include linux/config.h if AUTOCONF_INCLUDED is not
-+ * set. This is defined through autoconf.h which is included through the
-+ * linux kernel build macros.
-+ *
-+ * Revision 1.12.2.1 2006/02/15 05:35:14 paul
-+ * Patch by David McCullough <davidm@snapgear.com>
-+ * If you setup a tunnel without ESP it doesn't work. It used to work in
-+ * an older openswan version but stopped when klips was modified to deal
-+ * with the pulled IP header on the received SKB's.
-+ *
-+ * The code in ipsec_ah.c still thinks the IP header is there and runs the
-+ * hash on the incorrect data.
-+ *
-+ * Revision 1.12 2005/04/29 05:10:22 mcr
-+ * removed from extraenous includes to make unit testing easier.
-+ *
-+ * Revision 1.11 2005/04/15 19:50:55 mcr
-+ * adjustments to use proper skb fields for data.
-+ *
-+ * Revision 1.10 2004/09/14 00:22:57 mcr
-+ * adjustment of MD5* functions.
-+ *
-+ * Revision 1.9 2004/09/13 02:22:47 mcr
-+ * #define inet_protocol if necessary.
-+ *
-+ * Revision 1.8 2004/09/06 18:35:48 mcr
-+ * 2.6.8.1 gets rid of inet_protocol->net_protocol compatibility,
-+ * so adjust for that.
-+ *
-+ * Revision 1.7 2004/08/22 05:00:48 mcr
-+ * if we choose to compile the file, we want the contents,
-+ * so don't pull any punches.
-+ *
-+ * Revision 1.6 2004/08/17 03:27:23 mcr
-+ * klips 2.6 edits.
-+ *
-+ * Revision 1.5 2004/08/14 03:28:24 mcr
-+ * fixed log comment to remove warning about embedded comment.
-+ *
-+ * Revision 1.4 2004/08/04 15:57:07 mcr
-+ * moved des .h files to include/des/ *
-+ * included 2.6 protocol specific things
-+ * started at NAT-T support, but it will require a kernel patch.
-+ *
-+ * Revision 1.3 2004/07/10 19:11:18 mcr
-+ * CONFIG_IPSEC -> CONFIG_KLIPS.
-+ *
-+ * Revision 1.2 2004/04/06 02:49:25 mcr
-+ * pullup of algo code from alg-branch.

-+ * Revision 1.5 2004/08/17 03:27:23 mcr
-+ * klips 2.6 edits.
-+ *
-+ * Revision 1.4 2004/08/04 15:57:07 mcr
-+ * moved des .h files to include/des/ *
-+ * included 2.6 protocol specific things
-+ * started at NAT-T support, but it will require a kernel patch.
-+ *
-+ * Revision 1.3 2004/07/10 19:11:18 mcr
-+ * CONFIG_IPSEC -> CONFIG_KLIPS.
-+ *
-+ * Revision 1.2 2004/04/06 02:49:25 mcr

-+ * Revision 1.104.2.4 2006/10/06 21:39:26 paul
-+ * Fix for 2.6.18+ only include linux/config.h if AUTOCONF_INCLUDED is not
-+ * set. This is defined through autoconf.h which is included through the
-+ * linux kernel build macros.
-+ *
-+ * Revision 1.104.2.3 2006/07/31 15:25:20 paul
-+ * Check for NETKEY backport in Debian using IPSKB_XFRM_TUNNEL_SIZE to
-+ * determine wether inet_add_protocol needs the protocol argument.
-+ *
-+ * Revision 1.104.2.2 2006/04/20 16:33:06 mcr
-+ * remove all of CONFIG_KLIPS_ALG --- one can no longer build without it.
-+ * Fix in-kernel module compilation. Sub-makefiles do not work.
-+ *
-+ * Revision 1.104.2.1 2005/08/12 01:18:20 ken
-+ * Warn people who don't have NAT-T patch applied, but try and compile NAT-T code

-+ * Revision 1.105 2005/08/12 00:56:33 mcr
-+ * add warning for people who didn't apply nat-t patch.
-+ *
-+ * Revision 1.104 2005/07/08 15:51:41 mcr
-+ * removed duplicate NAT-T code.
-+ * if CONFIG_IPSEC_NAT_TRAVERSAL isn't defined, then there is no issue.
-+ *
-+ * Revision 1.103 2005/07/08 03:02:05 paul
-+ * Fixed garbled define that accidentally got commited to the real tree.
-+ *
-+ * Revision 1.102 2005/07/08 02:56:37 paul
-+ * gcc4 fixes that were not commited because vault was down
-+ *
-+ * Revision 1.101 2005/04/29 05:10:22 mcr
-+ * removed from extraenous includes to make unit testing easier.
-+ *
-+ * Revision 1.100 2005/04/10 22:56:09 mcr
-+ * change to udp.c registration API.
-+ *
-+ * Revision 1.99 2005/04/08 18:26:13 mcr
-+ * register with udp.c, the klips26 encap receive function
-+ *
-+ * Revision 1.98 2004/09/13 02:23:18 mcr
-+ * #define inet_protocol if necessary.
-+ *
-+ * Revision 1.97 2004/09/06 18:35:49 mcr
-+ * 2.6.8.1 gets rid of inet_protocol->net_protocol compatibility,
-+ * so adjust for that.
-+ *
-+ * Revision 1.96 2004/08/17 03:27:23 mcr
-+ * klips 2.6 edits.
-+ *
-+ * Revision 1.95 2004/08/03 18:19:08 mcr
-+ * in 2.6, use "net_device" instead of #define device->net_device.
-+ * this probably breaks 2.0 compiles.
-+ *
-+ * Revision 1.94 2004/07/10 19:11:18 mcr
-+ * CONFIG_IPSEC -> CONFIG_KLIPS.
-+ *

-+ * preliminary (untested by FS-team) 2.5 patches.
-+ *
-+ * Revision 1.88 2003/06/22 20:05:36 mcr
-+ * clarified why IPCOMP was not being registered, and put a new
-+ * #ifdef in rather than #if 0.
-+ *

-+ * Added a lock to the global ipsec_sadb struct for future use.

-+ * Move ipsec_prng outside debug code.
-+ *

-+ * Revision 1.78 2002/01/29 17:17:55 mcr
-+ * moved include of ipsec_param.h to after include of linux/kernel.h
-+ * otherwise, it seems that some option that is set in ipsec_param.h
-+ * screws up something subtle in the include path to kernel.h, and
-+ * it complains on the snprintf() prototype.
-+ *
-+ * Revision 1.77 2002/01/29 04:00:51 mcr
-+ * more excise of kversions.h header.
-+ *
-+ * Revision 1.76 2002/01/29 02:13:17 mcr

-+ * Merge MCR's ipsec_sa, eroute, proc and struct lifetime changes.

-+ * beginnings of /proc/net/ipsec dir.

-+ * Revision 1.171.2.11 2007/04/28 20:46:40 paul
-+ * Added compile time switch for -DDISABLE_UDP_CHECKSUM that seems to be
-+ * breaking IPsec+NAT+Transport mode with NAT-OA. Enabled this per default
-+ * via Makefile.inc's USERCOMPILE flags.
-+ *
-+ * Revision 1.171.2.10 2006/10/06 21:39:26 paul
-+ * Fix for 2.6.18+ only include linux/config.h if AUTOCONF_INCLUDED is not
-+ * set. This is defined through autoconf.h which is included through the
-+ * linux kernel build macros.
-+ *
-+ * Revision 1.171.2.9 2006/07/30 02:09:33 paul
-+ * Author: Bart Trojanowski <bart@xelerance.com>
-+ * This fixes a NATT+ESP bug in rcv path.
-+ *
-+ * We only want to test NATT policy on the ESP packet. Doing so on the
-+ * bundled SA breaks because the next layer does not know anything about
-+ * NATT.
-+ *
-+ * Fix just puts an if(proto == IPPROTO_ESP) around the NATT policy check.
-+ *
-+ * Revision 1.171.2.8 2006/07/29 05:03:04 paul
-+ * Added check for new version of skb_linearize that only takes 1 argument,

-+ *
-+ * Revision 1.171.2.6 2005/12/07 06:07:04 paul
-+ * comment out KLIPS_DEC_USE in ipsec_rcv_decap. Likely an artifact from
-+ * refactoring. http://bugs.xelerance.com/view.php?id=454

-+ * Revision 1.138 2003/12/24 19:46:52 mcr
-+ * if sock.h patch has not been applied, then define appropriate
-+ * structure so we can use it. This is serious inferior, and
-+ * depends upon the concept that the structure in question is

-+ *
-+ * Revision 1.137 2003/12/22 19:40:57 mcr

-+ *
-+ * Fixed AH decapsulation pointer update bug and added some comments and
-+ * debugging.
-+ * This bug was caught by west-ah-0[12].
-+ *
-+ * Revision 1.126 2002/11/04 05:03:43 mcr
-+ * fixes for IPCOMP. There were two problems:
-+ * 1) the irs->ipp pointer was not being updated properly after
-+ * the ESP descryption. The meant nothing for IPIP, as the
-+ * later IP header overwrote the earlier one.
-+ * 2) the more serious problem was that skb_decompress will
-+ * usually allocate a new SKB, so we have to make sure that
-+ * it doesn't get lost.
-+ * #2 meant removing the skb argument from the ->decrypt routine
-+ * and moving it to the irs->skb, so it could be value/result.

-+ *
-+ * Revision 1.112 2002/09/16 21:19:15 mcr
-+ * fixes for west-ah-icmp-01 - length of AH header must be
-+ * calculated properly, and next_header field properly copied.
-+ *
-+ * Revision 1.111 2002/09/10 02:45:56 mcr
-+ * re-factored the ipsec_rcv function into several functions,

-+ * include to deal with differences in kernel source.

-+ * Revision 1.99 2002/01/28 21:40:59 mcr
-+ * should use #if to test boolean option rather than #ifdef.

-+ * The data structure for the keys is a radix tree with one way
-+ * branching removed. The index rj_b at an internal node n represents a bit
-+ * position to be tested. The tree is arranged so that all descendants
-+ * of a node n have keys whose bits all agree up to position rj_b - 1.
-+ * (We say the index of n is rj_b.)
-+ *
-+ * There is at least one descendant which has a one bit at position rj_b,
-+ * and at least one with a zero there.
-+ *
-+ * A route is determined by a pair of key and mask. We require that the
-+ * bit-wise logical and of the key and mask to be the key.
-+ * We define the index of a route to associated with the mask to be
-+ * the first bit number in the mask where 0 occurs (with bit number 0
-+ * representing the highest order bit).
-+ *
-+ * We say a mask is normal if every bit is 0, past the index of the mask.
-+ * If a node n has a descendant (k, m) with index(m) == index(n) == rj_b,
-+ * and m is a normal mask, then the route applies to every descendant of n.
-+ * If the index(m) < rj_b, this implies the trailing last few bits of k
-+ * before bit b are all 0, (and hence consequently true of every descendant
-+ * of n), so the route applies to all descendants of the node as well.
-+ *
-+ * The present version of the code makes no use of normal routes,
-+ * but similar logic shows that a non-normal mask m such that
-+ * index(m) <= index(n) could potentially apply to many children of n.
-+ * Thus, for each non-host route, we attach its mask to a list at an internal

-Submitted By: Kevin P. Fleming <kpfleming at linuxfromscratch dot org>
-Date: 2004-05-02
-Initial Package Version: 5beta
-Origin: http://archives.linuxfromscratch.org/mail-archives/blfs-dev/2003-January/001960.html
-Description: The patch was created from the portmap modified package by Mark Heerdink.
-This patch provides the following improvements:
- * Link against dynamic tcp_wrappers.
- * Create an install target for portmap.
- * Compilation and security fixes.
- * Documentation fixes.
-
-Originally created by Tushar Teredesai, updated by kpfleming to ensure
-portmap will compile without tcp_wrappers installed.

-+.Os BSD 4.3
-+.Sh NAME
-+.Nm portmap
-+.Nd
-+.Tn DARPA
-+port to
-+.Tn RPC
-+program number mapper
-+.Sh SYNOPSIS
-+.Nm portmap
-+.Op Fl d
-+.Op Fl v
-+.Sh DESCRIPTION
-+.Nm Portmap
-+is a server that converts
-+.Tn RPC
-+program numbers into
-+.Tn DARPA
-+protocol port numbers.
-+It must be running in order to make
-+.Tn RPC
-+calls.
-+.Pp
-+When an
-+.Tn RPC
-+server is started, it will tell
-+.Nm portmap
-+what port number it is listening to, and what
-+.Tn RPC
-+program numbers it is prepared to serve.
-+When a client wishes to make an
-+.Tn RPC
-+call to a given program number,
-+it will first contact
-+.Nm portmap
-+on the server machine to determine
-+the port number where
-+.Tn RPC
-+packets should be sent.
-+.Pp
-+.Nm Portmap
-+must be started before any
-+.Tn RPC
-+servers are invoked.
-+.Pp
-+Normally
-+.Nm portmap
-+forks and dissociates itself from the terminal
-+like any other daemon.
-+.Nm Portmap
-+then logs errors using
-+.Xr syslog 3 .
-+.Pp
-+Option available:
-+.Bl -tag -width Ds
-+.It Fl d
-+(debug) prevents
-+.Nm portmap
-+from running as a daemon,
-+and causes errors and debugging information
-+to be printed to the standard error output.
-+.It Fl v
-+(verbose) run
-+.Nm portmap
-+in verbose mode.
-+.El
-+
-+This
-+.Nm portmap
-+version is protected by the
-+.Nm tcp_wrapper
-+library. You have to give the clients access to
-+.Nm portmap
-+if they should be allowed to use it. To allow connects from clients of
-+the .bar.com domain you could use the following line in /etc/hosts.allow:
-+
-+portmap: .bar.com
-+
-+You have to use the daemon name
-+.Nm portmap
-+for the daemon name (even if the binary has a different name). For the
-+client names you can only use the keyword ALL or IP addresses (NOT
-+host or domain names).
-+
-+For further information please have a look at the
-+.Xr tcpd 8 ,
-+.Xr hosts_allow 5
-+and
-+.Xr hosts_access 5
-+manual pages.
-+

-+.Xr hosts_access 5
-+.Xr hosts_options 5
-+.Sh BUGS
-+If
-+.Nm portmap
-+crashes, all servers must be restarted.

-+=============
-+tmgr.atom_max_size=N
-+ Atoms containing more than N blocks will be forced to commit.
-+ N is decimal.

-+tmgr.atom_max_flushers=N
-+ Limit of concurrent flushers for one atom. 0 means no limit.
-+ Default is 0.
-+
-+tree.cbk_cache.nr_slots=N
-+ Number of slots in the cbk cache.
-+
-+flush.relocate_threshold=N
-+ If flush finds more than N adjacent dirty leaf-level blocks it
-+ will force them to be relocated.
-+ Default is 64.
-+
-+flush.relocate_distance=N
-+ If flush finds can find a block allocation closer than at most
-+ N from the preceder it will relocate to that position.
-+ Default is 64.
-+
-+flush.scan_maxnodes=N
-+ The maximum number of nodes to scan left on a level during
-+ flush.
-+ Default is 10000.
-+
-+optimal_io_size=N
-+ Preferred IO size. This value is used to set st_blksize of
-+ struct stat.
-+ Default is 65536.
-+
-+bsdgroups
-+ Turn on BSD-style gid assignment.
-+
-+32bittimes
-+ By default file in reiser4 have 64 bit timestamps. Files
-+ created when filesystem is mounted with 32bittimes mount
-+ option will get 32 bit timestamps.
-+
-+mtflush
-+ Turn off concurrent flushing.
-+
-+nopseudo
-+ Disable pseudo files support. See
-+ http://namesys.com/v4/pseudo.html for more about pseudo files.
-+
-+dont_load_bitmap
-+ Don't load all bitmap blocks at mount time, it is useful for
-+ machines with tiny RAM and large disks.

-+ Reiser4 is a filesystem that performs all filesystem operations
-+ as atomic transactions, which means that it either performs a
-+ write, or it does not, and in the event of a crash it does not
-+ partially perform it or corrupt it.
-+
-+ It stores files in dancing trees, which are like balanced trees but
-+ faster. It packs small files together so that they share blocks
-+ without wasting space. This means you can use it to store really
-+ small files. It also means that it saves you disk space. It avoids
-+ hassling you with anachronisms like having a maximum number of
-+ inodes, and wasting space if you use less than that number.
-+
-+ Reiser4 is a distinct filesystem type from reiserfs (V3).

-+Reiser4 is hereby licensed under the GNU General

-+files are licensed under the GPL. The portions of them owned by Hans
-+Reiser, or authorized to be licensed by him, have been in the past,
-+and likely will be in the future, licensed to other parties under

-+want it to be owned by Hans Reiser, put your copyright label on that
-+code so the poor blight and his customers can keep things straight.
-+All portions of governed files not labeled otherwise are owned by Hans
-+Reiser, and by adding your code to it, widely distributing it to
-+others or sending us a patch, and leaving the sentence in stating that
-+licensing is governed by the statement in this file, you accept this.
-+It will be a kindness if you identify whether Hans Reiser is allowed
-+to license code labeled as owned by you on your behalf other than
-+under the GPL, because he wants to know if it is okay to do so and put
-+a check in the mail to you (for non-trivial improvements) when he
-+makes his next sale. He makes no guarantees as to the amount if any,
-+though he feels motivated to motivate contributors, and you can surely
-+discuss this with him before or after contributing. You have the
-+right to decline to allow him to license your code contribution other
-+than under the GPL.
-+
-+Further licensing options are available for commercial and/or other
-+interests directly from Hans Reiser: reiser@namesys.com. If you interpret
-+the GPL as not allowing those additional licensing options, you read
-+it wrongly, and Richard Stallman agrees with me, when carefully read
-+you can see that those restrictions on additional terms do not apply
-+to the owner of the copyright, and my interpretation of this shall
-+govern for this license.
-+
-+[END LICENSING]
-+
-+Reiser4 is a file system based on dancing tree algorithms, and is
-+described at http://www.namesys.com
-+
-+mkfs.reiser4 and other utilities are on our webpage or wherever your
-+Linux provider put them. You really want to be running the latest
-+version off the website if you use fsck.
-+
-+Yes, if you update your reiser4 kernel module you do have to
-+recompile your kernel, most of the time. The errors you get will be
-+quite cryptic if your forget to do so.
-+
-+Hideous Commercial Pitch: Spread your development costs across other OS
-+vendors. Select from the best in the world, not the best in your
-+building, by buying from third party OS component suppliers. Leverage
-+the software component development power of the internet. Be the most
-+aggressive in taking advantage of the commercial possibilities of
-+decentralized internet development, and add value through your branded
-+integration that you sell as an operating system. Let your competitors
-+be the ones to compete against the entire internet by themselves. Be
-+hip, get with the new economic trend, before your competitors do. Send
-+email to reiser@namesys.com
-+
-+Hans Reiser was the primary architect of Reiser4, but a whole team
-+chipped their ideas in. He invested everything he had into Namesys
-+for 5.5 dark years of no money before Reiser3 finally started to work well
-+enough to bring in money. He owns the copyright.
-+
-+DARPA was the primary sponsor of Reiser4. DARPA does not endorse
-+Reiser4, it merely sponsors it. DARPA is, in solely Hans's personal
-+opinion, unique in its willingness to invest into things more
-+theoretical than the VC community can readily understand, and more
-+longterm than allows them to be sure that they will be the ones to
-+extract the economic benefits from. DARPA also integrated us into a
-+security community that transformed our security worldview.
-+
-+Vladimir Saveliev is our lead programmer, with us from the beginning,
-+and he worked long hours writing the cleanest code. This is why he is
-+now the lead programmer after years of commitment to our work. He
-+always made the effort to be the best he could be, and to make his
-+code the best that it could be. What resulted was quite remarkable. I
-+don't think that money can ever motivate someone to work the way he
-+did, he is one of the most selfless men I know.
-+
-+Alexander Lyamin was our sysadmin, and helped to educate us in
-+security issues. Moscow State University and IMT were very generous
-+in the internet access they provided us, and in lots of other little
-+ways that a generous institution can be.
-+
-+Alexander Zarochentcev (sometimes known as zam, or sasha), wrote the
-+locking code, the block allocator, and finished the flushing code.
-+His code is always crystal clean and well structured.
-+
-+Nikita Danilov wrote the core of the balancing code, the core of the
-+plugins code, and the directory code. He worked a steady pace of long
-+hours that produced a whole lot of well abstracted code. He is our
-+senior computer scientist.
-+
-+Vladimir Demidov wrote the parser. Writing an in kernel parser is
-+something very few persons have the skills for, and it is thanks to
-+him that we can say that the parser is really not so big compared to
-+various bits of our other code, and making a parser work in the kernel
-+was not so complicated as everyone would imagine mainly because it was
-+him doing it...
-+
-+Joshua McDonald wrote the transaction manager, and the flush code.
-+The flush code unexpectedly turned out be extremely hairy for reasons
-+you can read about on our web page, and he did a great job on an
-+extremely difficult task.
-+
-+Nina Reiser handled our accounting, government relations, and much
-+more.
-+
-+Ramon Reiser developed our website.
-+
-+Beverly Palmer drew our graphics.
-+
-+Vitaly Fertman developed librepair, userspace plugins repair code, fsck
-+and worked with Umka on developing libreiser4 and userspace plugins.
-+
-+Yury Umanets (aka Umka) developed libreiser4, userspace plugins and
-+userspace tools (reiser4progs).
-+
-+Oleg Drokin (aka Green) is the release manager who fixes everything.
-+It is so nice to have someone like that on the team. He (plus Chris
-+and Jeff) make it possible for the entire rest of the Namesys team to
-+focus on Reiser4, and he fixed a whole lot of Reiser4 bugs also. It
-+is just amazing to watch his talent for spotting bugs in action.

-+/* THE REISER4 DISK SPACE RESERVATION SCHEME. */
-+
-+/* We need to be able to reserve enough disk space to ensure that an atomic
-+ operation will have enough disk space to flush (see flush.c and
-+ http://namesys.com/v4/v4.html) and commit it once it is started.
-+
-+ In our design a call for reserving disk space may fail but not an actual
-+ block allocation.
-+
-+ All free blocks, already allocated blocks, and all kinds of reserved blocks
-+ are counted in different per-fs block counters.
-+
-+ A reiser4 super block's set of block counters currently is:
-+
-+ free -- free blocks,
-+ used -- already allocated blocks,
-+
-+ grabbed -- initially reserved for performing an fs operation, those blocks
-+ are taken from free blocks, then grabbed disk space leaks from grabbed
-+ blocks counter to other counters like "fake allocated", "flush
-+ reserved", "used", the rest of not used grabbed space is returned to
-+ free space at the end of fs operation;
-+
-+ fake allocated -- counts all nodes without real disk block numbers assigned,
-+ we have separate accounting for formatted and unformatted
-+ nodes (for easier debugging);
-+
-+ flush reserved -- disk space needed for flushing and committing an atom.
-+ Each dirty already allocated block could be written as a
-+ part of atom's overwrite set or as a part of atom's
-+ relocate set. In both case one additional block is needed,
-+ it is used as a wandered block if we do overwrite or as a
-+ new location for a relocated block.
-+
-+ In addition, blocks in some states are counted on per-thread and per-atom
-+ basis. A reiser4 context has a counter of blocks grabbed by this transaction
-+ and the sb's grabbed blocks counter is a sum of grabbed blocks counter values
-+ of each reiser4 context. Each reiser4 atom has a counter of "flush reserved"
-+ blocks, which are reserved for flush processing and atom commit. */
-+
-+/* AN EXAMPLE: suppose we insert new item to the reiser4 tree. We estimate
-+ number of blocks to grab for most expensive case of balancing when the leaf
-+ node we insert new item to gets split and new leaf node is allocated.
-+
-+ So, we need to grab blocks for
-+
-+ 1) one block for possible dirtying the node we insert an item to. That block
-+ would be used for node relocation at flush time or for allocating of a
-+ wandered one, it depends what will be a result (what set, relocate or
-+ overwrite the node gets assigned to) of the node processing by the flush
-+ algorithm.
-+
-+ 2) one block for either allocating a new node, or dirtying of right or left
-+ clean neighbor, only one case may happen.
-+
-+ VS-FIXME-HANS: why can only one case happen? I would expect to see dirtying of left neighbor, right neighbor, current
-+ node, and creation of new node. have I forgotten something? email me.
-+
-+ These grabbed blocks are counted in both reiser4 context "grabbed blocks"
-+ counter and in the fs-wide one (both ctx->grabbed_blocks and
-+ sbinfo->blocks_grabbed get incremented by 2), sb's free blocks counter is
-+ decremented by 2.
-+
-+ Suppose both two blocks were spent for dirtying of an already allocated clean
-+ node (one block went from "grabbed" to "flush reserved") and for new block
-+ allocating (one block went from "grabbed" to "fake allocated formatted").
-+
-+ Inserting of a child pointer to the parent node caused parent node to be
-+ split, the balancing code takes care about this grabbing necessary space
-+ immediately by calling reiser4_grab with BA_RESERVED flag set which means
-+ "can use the 5% reserved disk space".
-+
-+ At this moment insertion completes and grabbed blocks (if they were not used)
-+ should be returned to the free space counter.
-+
-+ However the atom life-cycle is not completed. The atom had one "flush
-+ reserved" block added by our insertion and the new fake allocated node is
-+ counted as a "fake allocated formatted" one. The atom has to be fully
-+ processed by flush before commit. Suppose that the flush moved the first,
-+ already allocated node to the atom's overwrite list, the new fake allocated
-+ node, obviously, went into the atom relocate set. The reiser4 flush
-+ allocates the new node using one unit from "fake allocated formatted"
-+ counter, the log writer uses one from "flush reserved" for wandered block
-+ allocation.
-+
-+ And, it is not the end. When the wandered block is deallocated after the
-+ atom gets fully played (see wander.c for term description), the disk space
-+ occupied for it is returned to free blocks. */
-+
-+/* BLOCK NUMBERS */
-+
-+/* Any reiser4 node has a block number assigned to it. We use these numbers for
-+ indexing in hash tables, so if a block has not yet been assigned a location
-+ on disk we need to give it a temporary fake block number.
-+
-+ Current implementation of reiser4 uses 64-bit integers for block numbers. We
-+ use highest bit in 64-bit block number to distinguish fake and real block
-+ numbers. So, only 63 bits may be used to addressing of real device
-+ blocks. That "fake" block numbers space is divided into subspaces of fake
-+ block numbers for data blocks and for shadow (working) bitmap blocks.
-+
-+ Fake block numbers for data blocks are generated by a cyclic counter, which
-+ gets incremented after each real block allocation. We assume that it is
-+ impossible to overload this counter during one transaction life. */

-+/* Functions to "carry" tree modification(s) upward. */
-+/* Tree is modified one level at a time. As we modify a level we accumulate a
-+ set of changes that need to be propagated to the next level. We manage
-+ node locking such that any searches that collide with carrying are
-+ restarted, from the root if necessary.
-+
-+ Insertion of a new item may result in items being moved among nodes and
-+ this requires the delimiting key to be updated at the least common parent
-+ of the nodes modified to preserve search tree invariants. Also, insertion
-+ may require allocation of a new node. A pointer to the new node has to be
-+ inserted into some node on the parent level, etc.
-+
-+ Tree carrying is meant to be analogous to arithmetic carrying.
-+
-+ A carry operation is always associated with some node (&carry_node).
-+
-+ Carry process starts with some initial set of operations to be performed
-+ and an initial set of already locked nodes. Operations are performed one
-+ by one. Performing each single operation has following possible effects:
-+
-+ - content of carry node associated with operation is modified
-+ - new carry nodes are locked and involved into carry process on this level
-+ - new carry operations are posted to the next level
-+
-+ After all carry operations on this level are done, process is repeated for
-+ the accumulated sequence on carry operations for the next level. This
-+ starts by trying to lock (in left to right order) all carry nodes
-+ associated with carry operations on the parent level. After this, we decide
-+ whether more nodes are required on the left of already locked set. If so,
-+ all locks taken on the parent level are released, new carry nodes are
-+ added, and locking process repeats.
-+
-+ It may happen that balancing process fails owing to unrecoverable error on
-+ some of upper levels of a tree (possible causes are io error, failure to
-+ allocate new node, etc.). In this case we should unmount the filesystem,
-+ rebooting if it is the root, and possibly advise the use of fsck.
-+
-+ USAGE:
-+
-+ int some_tree_operation( znode *node, ... )
-+ {
-+ // Allocate on a stack pool of carry objects: operations and nodes.
-+ // Most carry processes will only take objects from here, without
-+ // dynamic allocation.
-+
-+I feel uneasy about this pool. It adds to code complexity, I understand why it exists, but.... -Hans
-+
-+ carry_pool pool;
-+ carry_level lowest_level;
-+ carry_op *op;
-+
-+ init_carry_pool( &pool );
-+ init_carry_level( &lowest_level, &pool );
-+
-+ // operation may be one of:
-+ // COP_INSERT --- insert new item into node
-+ // COP_CUT --- remove part of or whole node
-+ // COP_PASTE --- increase size of item
-+ // COP_DELETE --- delete pointer from parent node
-+ // COP_UPDATE --- update delimiting key in least
-+ // common ancestor of two
-+
-+ op = post_carry( &lowest_level, operation, node, 0 );
-+ if( IS_ERR( op ) || ( op == NULL ) ) {
-+ handle error
-+ } else {
-+ // fill in remaining fields in @op, according to carry.h:carry_op
-+ result = carry( &lowest_level, NULL );
-+ }
-+ done_carry_pool( &pool );
-+ }
-+
-+ When you are implementing node plugin method that participates in carry
-+ (shifting, insertion, deletion, etc.), do the following:
-+
-+ int foo_node_method( znode *node, ..., carry_level *todo )
-+ {
-+ carry_op *op;
-+
-+ ....
-+
-+ // note, that last argument to post_carry() is non-null
-+ // here, because @op is to be applied to the parent of @node, rather
-+ // than to the @node itself as in the previous case.
-+
-+ op = node_post_carry( todo, operation, node, 1 );
-+ // fill in remaining fields in @op, according to carry.h:carry_op
-+
-+ ....
-+
-+ }
-+
-+ BATCHING:
-+
-+ One of the main advantages of level-by-level balancing implemented here is
-+ ability to batch updates on a parent level and to peform them more
-+ efficiently as a result.
-+
-+ Description To Be Done (TBD).
-+
-+ DIFFICULTIES AND SUBTLE POINTS:
-+
-+ 1. complex plumbing is required, because:
-+
-+ a. effective allocation through pools is needed
-+
-+ b. target of operation is not exactly known when operation is
-+ posted. This is worked around through bitfields in &carry_node and
-+ logic in lock_carry_node()
-+
-+ c. of interaction with locking code: node should be added into sibling
-+ list when pointer to it is inserted into its parent, which is some time
-+ after node was created. Between these moments, node is somewhat in
-+ suspended state and is only registered in the carry lists
-+
-+ 2. whole balancing logic is implemented here, in particular, insertion
-+ logic is coded in make_space().
-+
-+ 3. special cases like insertion (add_tree_root()) or deletion
-+ (kill_tree_root()) of tree root and morphing of paste into insert
-+ (insert_paste()) have to be handled.
-+
-+ 4. there is non-trivial interdependency between allocation of new nodes
-+ and almost everything else. This is mainly due to the (1.c) above. I shall
-+ write about this later.

-+ It is possible that carry faces unrecoverable error, like unability to

-+ this situation. More sophisticated things like attempt to remount
-+ file-system as read-only can be implemented without much difficlties.
-+
-+ It is believed, that:
-+
-+ 1. in stead of panicking, all current transactions can be aborted rolling
-+ system back to the consistent state.
-+
-+Umm, if you simply panic without doing anything more at all, then all current
-+transactions are aborted and the system is rolled back to a consistent state,
-+by virtue of the design of the transactional mechanism. Well, wait, let's be
-+precise. If an internal node is corrupted on disk due to hardware failure,
-+then there may be no consistent state that can be rolled back to, so instead
-+we should say that it will rollback the transactions, which barring other
-+factors means rolling back to a consistent state.
-+
-+# Nikita: there is a subtle difference between panic and aborting
-+# transactions: machine doesn't reboot. Processes aren't killed. Processes
-+# don't using reiser4 (not that we care about such processes), or using other
-+# reiser4 mounts (about them we do care) will simply continue to run. With
-+# some luck, even application using aborted file system can survive: it will
-+# get some error, like EBADF, from each file descriptor on failed file system,
-+# but applications that do care about tolerance will cope with this (squid
-+# will).
-+
-+It would be a nice feature though to support rollback without rebooting
-+followed by remount, but this can wait for later versions.
-+
-+ 2. once isolated transactions will be implemented it will be possible to
-+ roll back offending transaction.
-+
-+2. is additional code complexity of inconsistent value (it implies that a broken tree should be kept in operation), so we must think about
-+it more before deciding if it should be done. -Hans

-+/* insert_paste_common() - common part of insert and paste operations
-+
-+ This function performs common part of COP_INSERT and COP_PASTE.
-+
-+ There are two ways in which insertion/paste can be requested:
-+
-+ . by directly supplying reiser4_item_data. In this case, op ->
-+ u.insert.type is set to COPT_ITEM_DATA.
-+
-+ . by supplying child pointer to which is to inserted into parent. In this
-+ case op -> u.insert.type == COPT_CHILD.
-+
-+ . by supplying key of new item/unit. This is currently only used during
-+ extent insertion
-+
-+ This is required, because when new node is allocated we don't know at what
-+ position pointer to it is to be stored in the parent. Actually, we don't
-+ even know what its parent will be, because parent can be re-balanced
-+ concurrently and new node re-parented, and because parent can be full and
-+ pointer to the new node will go into some other node.
-+
-+ insert_paste_common() resolves pointer to child node into position in the
-+ parent by calling find_new_child_coord(), that fills
-+ reiser4_item_data. After this, insertion/paste proceeds uniformly.
-+
-+ Another complication is with finding free space during pasting. It may
-+ happen that while shifting items to the neighbors and newly allocated
-+ nodes, insertion coord can no longer be in the item we wanted to paste
-+ into. At this point, paste becomes (morphs) into insert. Moreover free
-+ space analysis has to be repeated, because amount of space required for
-+ insertion is different from that of paste (item header overhead, etc).
-+
-+ This function "unifies" different insertion modes (by resolving child
-+ pointer or key into insertion coord), and then calls make_space() to free
-+ enough space in the node by shifting data to the left and right and by
-+ allocating new nodes if necessary. Carry operation knows amount of space
-+ required for its completion. After enough free space is obtained, caller of
-+ this function (carry_{insert,paste,etc.}) performs actual insertion/paste
-+ by calling item plugin method.

-+ * to the file system, they assume that some transaction is already underway,
-+ * and usually bail out, because starting nested transaction would most likely
-+ * lead to the deadlock. This gives false positives with reiser4, because we

-+ * Extents on the twig level (EOTTL) handling.
-+ *
-+ * EOTTL poses some problems to the tree traversal, that are better explained
-+ * by example.
-+ *
-+ * Suppose we have block B1 on the twig level with the following items:
-+ *
-+ * 0. internal item I0 with key (0:0:0:0) (locality, key-type, object-id,
-+ * offset)
-+ * 1. extent item E1 with key (1:4:100:0), having 10 blocks of 4k each
-+ * 2. internal item I2 with key (10:0:0:0)
-+ *
-+ * We are trying to insert item with key (5:0:0:0). Lookup finds node B1, and
-+ * then intra-node lookup is done. This lookup finished on the E1, because the
-+ * key we are looking for is larger than the key of E1 and is smaller than key
-+ * the of I2.
-+ *
-+ * Here search is stuck.
-+ *
-+ * After some thought it is clear what is wrong here: extents on the twig level
-+ * break some basic property of the *search* tree (on the pretext, that they
-+ * restore property of balanced tree).
-+ *
-+ * Said property is the following: if in the internal node of the search tree
-+ * we have [ ... Key1 Pointer Key2 ... ] then, all data that are or will be
-+ * keyed in the tree with the Key such that Key1 <= Key < Key2 are accessible
-+ * through the Pointer.
-+ *
-+ * This is not true, when Pointer is Extent-Pointer, simply because extent
-+ * cannot expand indefinitely to the right to include any item with
-+ *
-+ * Key1 <= Key <= Key2.
-+ *
-+ * For example, our E1 extent is only responsible for the data with keys
-+ *
-+ * (1:4:100:0) <= key <= (1:4:100:0xffffffffffffffff), and
-+ *
-+ * so, key range
-+ *
-+ * ( (1:4:100:0xffffffffffffffff), (10:0:0:0) )
-+ *
-+ * is orphaned: there is no way to get there from the tree root.
-+ *
-+ * In other words, extent pointers are different than normal child pointers as
-+ * far as search tree is concerned, and this creates such problems.
-+ *
-+ * Possible solution for this problem is to insert our item into node pointed
-+ * to by I2. There are some problems through:
-+ *
-+ * (1) I2 can be in a different node.
-+ * (2) E1 can be immediately followed by another extent E2.
-+ *
-+ * (1) is solved by calling reiser4_get_right_neighbor() and accounting
-+ * for locks/coords as necessary.
-+ *
-+ * (2) is more complex. Solution here is to insert new empty leaf node and
-+ * insert internal item between E1 and E2 pointing to said leaf node. This is
-+ * further complicated by possibility that E2 is in a different node, etc.
-+ *
-+ * Problems:
-+ *
-+ * (1) if there was internal item I2 immediately on the right of an extent E1
-+ * we and we decided to insert new item S1 into node N2 pointed to by I2, then
-+ * key of S1 will be less than smallest key in the N2. Normally, search key
-+ * checks that key we are looking for is in the range of keys covered by the
-+ * node key is being looked in. To work around of this situation, while
-+ * preserving useful consistency check new flag CBK_TRUST_DK was added to the
-+ * cbk falgs bitmask. This flag is automatically set on entrance to the
-+ * coord_by_key() and is only cleared when we are about to enter situation
-+ * described above.
-+ *
-+ * (2) If extent E1 is immediately followed by another extent E2 and we are
-+ * searching for the key that is between E1 and E2 we only have to insert new
-+ * empty leaf node when coord_by_key was called for insertion, rather than just
-+ * for lookup. To distinguish these cases, new flag CBK_FOR_INSERT was added to
-+ * the cbk falgs bitmask. This flag is automatically set by coord_by_key calls
-+ * performed by insert_by_key() and friends.
-+ *
-+ * (3) Insertion of new empty leaf node (possibly) requires balancing. In any
-+ * case it requires modification of node content which is only possible under
-+ * write lock. It may well happen that we only have read lock on the node where
-+ * new internal pointer is to be inserted (common case: lookup of non-existent
-+ * stat-data that fells between two extents). If only read lock is held, tree
-+ * traversal is restarted with lock_level modified so that next time we hit
-+ * this problem, write lock will be held. Once we have write lock, balancing
-+ * will be performed.

-+/* IMPLEMENTATION NOTES */
-+
-+/* PARENT-FIRST: Some terminology: A parent-first traversal is a way of assigning a total
-+ order to the nodes of the tree in which the parent is placed before its children, which
-+ are ordered (recursively) in left-to-right order. When we speak of a "parent-first preceder", it
-+ describes the node that "came before in forward parent-first order". When we speak of a
-+ "parent-first follower", it describes the node that "comes next in parent-first
-+ order" (alternatively the node that "came before in reverse parent-first order").
-+
-+ The following pseudo-code prints the nodes of a tree in forward parent-first order:
-+
-+ void parent_first (node)
-+ {
-+ print_node (node);
-+ if (node->level > leaf) {
-+ for (i = 0; i < num_children; i += 1) {
-+ parent_first (node->child[i]);
-+ }
-+ }
-+ }
-+*/
-+
-+/* JUST WHAT ARE WE TRYING TO OPTIMIZE, HERE? The idea is to optimize block allocation so
-+ that a left-to-right scan of the tree's data (i.e., the leaves in left-to-right order)
-+ can be accomplished with sequential reads, which results in reading nodes in their
-+ parent-first order. This is a read-optimization aspect of the flush algorithm, and
-+ there is also a write-optimization aspect, which is that we wish to make large
-+ sequential writes to the disk by allocating or reallocating blocks so that they can be
-+ written in sequence. Sometimes the read-optimization and write-optimization goals
-+ conflict with each other, as we discuss in more detail below.
-+*/
-+
-+/* STATE BITS: The flush code revolves around the state of the jnodes it covers. Here are
-+ the relevant jnode->state bits and their relevence to flush:
-+
-+ JNODE_DIRTY: If a node is dirty, it must be flushed. But in order to be written it
-+ must be allocated first. In order to be considered allocated, the jnode must have
-+ exactly one of { JNODE_OVRWR, JNODE_RELOC } set. These two bits are exclusive, and
-+ all dirtied jnodes eventually have one of these bits set during each transaction.
-+
-+ JNODE_CREATED: The node was freshly created in its transaction and has no previous
-+ block address, so it is unconditionally assigned to be relocated, although this is
-+ mainly for code-convenience. It is not being 'relocated' from anything, but in
-+ almost every regard it is treated as part of the relocate set. The JNODE_CREATED bit
-+ remains set even after JNODE_RELOC is set, so the actual relocate can be
-+ distinguished from the created-and-allocated set easily: relocate-set members
-+ (belonging to the preserve-set) have (JNODE_RELOC) set and created-set members which
-+ have no previous location to preserve have (JNODE_RELOC | JNODE_CREATED) set.
-+
-+ JNODE_OVRWR: The node belongs to atom's overwrite set. The flush algorithm made the
-+ decision to maintain the pre-existing location for this node and it will be written
-+ to the wandered-log.
-+
-+ JNODE_RELOC: The flush algorithm made the decision to relocate this block (if it was
-+ not created, see note above). A block with JNODE_RELOC set is eligible for
-+ early-flushing and may be submitted during flush_empty_queues. When the JNODE_RELOC
-+ bit is set on a znode, the parent node's internal item is modified and the znode is
-+ rehashed.
-+
-+ JNODE_SQUEEZABLE: Before shifting everything left, the flush algorithm scans the node
-+ and calls plugin->f.squeeze() method for its items. By this technology we update disk
-+ clusters of cryptcompress objects. Also if leftmost point that was found by flush scan
-+ has this flag (races with write(), rare case) the flush algorythm makes the decision
-+ to pass it to squalloc() in spite of its flushprepped status for squeezing, not for
-+ repeated allocation.
-+
-+ JNODE_FLUSH_QUEUED: This bit is set when a call to flush enters the jnode into its
-+ flush queue. This means the jnode is not on any clean or dirty list, instead it is
-+ moved to one of the flush queue (see flush_queue.h) object private list. This
-+ prevents multiple concurrent flushes from attempting to start flushing from the
-+ same node.
-+
-+ (DEAD STATE BIT) JNODE_FLUSH_BUSY: This bit was set during the bottom-up
-+ squeeze-and-allocate on a node while its children are actively being squeezed and
-+ allocated. This flag was created to avoid submitting a write request for a node
-+ while its children are still being allocated and squeezed. Then flush queue was
-+ re-implemented to allow unlimited number of nodes be queued. This flag support was
-+ commented out in source code because we decided that there was no reason to submit
-+ queued nodes before jnode_flush() finishes. However, current code calls fq_write()
-+ during a slum traversal and may submit "busy nodes" to disk. Probably we can
-+ re-enable the JNODE_FLUSH_BUSY bit support in future.
-+
-+ With these state bits, we describe a test used frequently in the code below,
-+ jnode_is_flushprepped() (and the spin-lock-taking jnode_check_flushprepped()). The
-+ test for "flushprepped" returns true if any of the following are true:
-+
-+ - The node is not dirty
-+ - The node has JNODE_RELOC set
-+ - The node has JNODE_OVRWR set
-+
-+ If either the node is not dirty or it has already been processed by flush (and assigned
-+ JNODE_OVRWR or JNODE_RELOC), then it is prepped. If jnode_is_flushprepped() returns
-+ true then flush has work to do on that node.
-+*/
-+
-+/* FLUSH_PREP_ONCE_PER_TRANSACTION: Within a single transaction a node is never
-+ flushprepped twice (unless an explicit call to flush_unprep is made as described in
-+ detail below). For example a node is dirtied, allocated, and then early-flushed to
-+ disk and set clean. Before the transaction commits, the page is dirtied again and, due
-+ to memory pressure, the node is flushed again. The flush algorithm will not relocate
-+ the node to a new disk location, it will simply write it to the same, previously
-+ relocated position again.
-+*/
-+
-+/* THE BOTTOM-UP VS. TOP-DOWN ISSUE: This code implements a bottom-up algorithm where we
-+ start at a leaf node and allocate in parent-first order by iterating to the right. At
-+ each step of the iteration, we check for the right neighbor. Before advancing to the
-+ right neighbor, we check if the current position and the right neighbor share the same
-+ parent. If they do not share the same parent, the parent is allocated before the right
-+ neighbor.
-+
-+ This process goes recursively up the tree and squeeze nodes level by level as long as
-+ the right neighbor and the current position have different parents, then it allocates
-+ the right-neighbors-with-different-parents on the way back down. This process is
-+ described in more detail in flush_squalloc_changed_ancestor and the recursive function
-+ squalloc_one_changed_ancestor. But the purpose here is not to discuss the
-+ specifics of the bottom-up approach as it is to contrast the bottom-up and top-down
-+ approaches.
-+
-+ The top-down algorithm was implemented earlier (April-May 2002). In the top-down
-+ approach, we find a starting point by scanning left along each level past dirty nodes,
-+ then going up and repeating the process until the left node and the parent node are
-+ clean. We then perform a parent-first traversal from the starting point, which makes
-+ allocating in parent-first order trivial. After one subtree has been allocated in this
-+ manner, we move to the right, try moving upward, then repeat the parent-first
-+ traversal.
-+
-+ Both approaches have problems that need to be addressed. Both are approximately the
-+ same amount of code, but the bottom-up approach has advantages in the order it acquires
-+ locks which, at the very least, make it the better approach. At first glance each one
-+ makes the other one look simpler, so it is important to remember a few of the problems
-+ with each one.
-+
-+ Main problem with the top-down approach: When you encounter a clean child during the
-+ parent-first traversal, what do you do? You would like to avoid searching through a
-+ large tree of nodes just to find a few dirty leaves at the bottom, and there is not an
-+ obvious solution. One of the advantages of the top-down approach is that during the
-+ parent-first traversal you check every child of a parent to see if it is dirty. In
-+ this way, the top-down approach easily handles the main problem of the bottom-up
-+ approach: unallocated children.
-+
-+ The unallocated children problem is that before writing a node to disk we must make
-+ sure that all of its children are allocated. Otherwise, the writing the node means
-+ extra I/O because the node will have to be written again when the child is finally
-+ allocated.
-+
-+ WE HAVE NOT YET ELIMINATED THE UNALLOCATED CHILDREN PROBLEM. Except for bugs, this
-+ should not cause any file system corruption, it only degrades I/O performance because a
-+ node may be written when it is sure to be written at least one more time in the same
-+ transaction when the remaining children are allocated. What follows is a description
-+ of how we will solve the problem.
-+*/
-+
-+/* HANDLING UNALLOCATED CHILDREN: During flush we may allocate a parent node then,
-+ proceeding in parent first order, allocate some of its left-children, then encounter a
-+ clean child in the middle of the parent. We do not allocate the clean child, but there
-+ may remain unallocated (dirty) children to the right of the clean child. If we were to
-+ stop flushing at this moment and write everything to disk, the parent might still
-+ contain unallocated children.
-+
-+ We could try to allocate all the descendents of every node that we allocate, but this
-+ is not necessary. Doing so could result in allocating the entire tree: if the root
-+ node is allocated then every unallocated node would have to be allocated before
-+ flushing. Actually, we do not have to write a node just because we allocate it. It is
-+ possible to allocate but not write a node during flush, when it still has unallocated
-+ children. However, this approach is probably not optimal for the following reason.
-+
-+ The flush algorithm is designed to allocate nodes in parent-first order in an attempt
-+ to optimize reads that occur in the same order. Thus we are read-optimizing for a
-+ left-to-right scan through all the leaves in the system, and we are hoping to
-+ write-optimize at the same time because those nodes will be written together in batch.
-+ What happens, however, if we assign a block number to a node in its read-optimized
-+ order but then avoid writing it because it has unallocated children? In that
-+ situation, we lose out on the write-optimization aspect because a node will have to be
-+ written again to the its location on the device, later, which likely means seeking back
-+ to that location.
-+
-+ So there are tradeoffs. We can choose either:
-+
-+ A. Allocate all unallocated children to preserve both write-optimization and
-+ read-optimization, but this is not always desirable because it may mean having to
-+ allocate and flush very many nodes at once.
-+
-+ B. Defer writing nodes with unallocated children, keep their read-optimized locations,
-+ but sacrifice write-optimization because those nodes will be written again.
-+
-+ C. Defer writing nodes with unallocated children, but do not keep their read-optimized
-+ locations. Instead, choose to write-optimize them later, when they are written. To
-+ facilitate this, we "undo" the read-optimized allocation that was given to the node so
-+ that later it can be write-optimized, thus "unpreparing" the flush decision. This is a
-+ case where we disturb the FLUSH_PREP_ONCE_PER_TRANSACTION rule described above. By a
-+ call to flush_unprep() we will: if the node was wandered, unset the JNODE_OVRWR bit;
-+ if the node was relocated, unset the JNODE_RELOC bit, non-deferred-deallocate its block
-+ location, and set the JNODE_CREATED bit, effectively setting the node back to an
-+ unallocated state.
-+
-+ We will take the following approach in v4.0: for twig nodes we will always finish
-+ allocating unallocated children (A). For nodes with (level > TWIG) we will defer
-+ writing and choose write-optimization (C).
-+
-+ To summarize, there are several parts to a solution that avoids the problem with
-+ unallocated children:
-+
-+ FIXME-ZAM: Still no one approach is implemented to eliminate the "UNALLOCATED CHILDREN"
-+ problem because there was an experiment which was done showed that we have 1-2 nodes
-+ with unallocated children for thousands of written nodes. The experiment was simple
-+ like coping / deletion of linux kernel sources. However the problem can arise in more
-+ complex tests. I think we have jnode_io_hook to insert a check for unallocated
-+ children and see what kind of problem we have.
-+
-+ 1. When flush reaches a stopping point (e.g., a clean node), it should continue calling
-+ squeeze-and-allocate on any remaining unallocated children. FIXME: Difficulty to
-+ implement: should be simple -- amounts to adding a while loop to jnode_flush, see
-+ comments in that function.
-+
-+ 2. When flush reaches flush_empty_queue(), some of the (level > TWIG) nodes may still
-+ have unallocated children. If the twig level has unallocated children it is an
-+ assertion failure. If a higher-level node has unallocated children, then it should be
-+ explicitly de-allocated by a call to flush_unprep(). FIXME: Difficulty to implement:
-+ should be simple.
-+
-+ 3. (CPU-Optimization) Checking whether a node has unallocated children may consume more
-+ CPU cycles than we would like, and it is possible (but medium complexity) to optimize
-+ this somewhat in the case where large sub-trees are flushed. The following observation
-+ helps: if both the left- and right-neighbor of a node are processed by the flush
-+ algorithm then the node itself is guaranteed to have all of its children allocated.
-+ However, the cost of this check may not be so expensive after all: it is not needed for
-+ leaves and flush can guarantee this property for twigs. That leaves only (level >
-+ TWIG) nodes that have to be checked, so this optimization only helps if at least three
-+ (level > TWIG) nodes are flushed in one pass, and the savings will be very small unless
-+ there are many more (level > TWIG) nodes. But if there are many (level > TWIG) nodes
-+ then the number of blocks being written will be very large, so the savings may be
-+ insignificant. That said, the idea is to maintain both the left and right edges of
-+ nodes that are processed in flush. When flush_empty_queue() is called, a relatively
-+ simple test will tell whether the (level > TWIG) node is on the edge. If it is on the
-+ edge, the slow check is necessary, but if it is in the interior then it can be assumed
-+ to have all of its children allocated. FIXME: medium complexity to implement, but
-+ simple to verify given that we must have a slow check anyway.
-+
-+ 4. (Optional) This part is optional, not for v4.0--flush should work independently of
-+ whether this option is used or not. Called RAPID_SCAN, the idea is to amend the
-+ left-scan operation to take unallocated children into account. Normally, the left-scan
-+ operation goes left as long as adjacent nodes are dirty up until some large maximum
-+ value (FLUSH_SCAN_MAXNODES) at which point it stops and begins flushing. But scan-left
-+ may stop at a position where there are unallocated children to the left with the same
-+ parent. When RAPID_SCAN is enabled, the ordinary scan-left operation stops after
-+ FLUSH_RELOCATE_THRESHOLD, which is much smaller than FLUSH_SCAN_MAXNODES, then procedes
-+ with a rapid scan. The rapid scan skips all the interior children of a node--if the
-+ leftmost child of a twig is dirty, check its left neighbor (the rightmost child of the
-+ twig to the left). If the left neighbor of the leftmost child is also dirty, then
-+ continue the scan at the left twig and repeat. This option will cause flush to
-+ allocate more twigs in a single pass, but it also has the potential to write many more
-+ nodes than would otherwise be written without the RAPID_SCAN option. RAPID_SCAN
-+ was partially implemented, code removed August 12, 2002 by JMACD.
-+*/
-+
-+/* FLUSH CALLED ON NON-LEAF LEVEL. Most of our design considerations assume that the
-+ starting point for flush is a leaf node, but actually the flush code cares very little
-+ about whether or not this is true. It is possible that all the leaf nodes are flushed
-+ and dirty parent nodes still remain, in which case jnode_flush() is called on a
-+ non-leaf argument. Flush doesn't care--it treats the argument node as if it were a
-+ leaf, even when it is not. This is a simple approach, and there may be a more optimal
-+ policy but until a problem with this approach is discovered, simplest is probably best.
-+
-+ NOTE: In this case, the ordering produced by flush is parent-first only if you ignore
-+ the leaves. This is done as a matter of simplicity and there is only one (shaky)
-+ justification. When an atom commits, it flushes all leaf level nodes first, followed
-+ by twigs, and so on. With flushing done in this order, if flush is eventually called
-+ on a non-leaf node it means that (somehow) we reached a point where all leaves are
-+ clean and only internal nodes need to be flushed. If that it the case, then it means
-+ there were no leaves that were the parent-first preceder/follower of the parent. This
-+ is expected to be a rare case, which is why we do nothing special about it. However,
-+ memory pressure may pass an internal node to flush when there are still dirty leaf
-+ nodes that need to be flushed, which could prove our original assumptions
-+ "inoperative". If this needs to be fixed, then scan_left/right should have
-+ special checks for the non-leaf levels. For example, instead of passing from a node to
-+ the left neighbor, it should pass from the node to the left neighbor's rightmost
-+ descendent (if dirty).
-+
-+*/
-+
-+/* UNIMPLEMENTED AS YET: REPACKING AND RESIZING. We walk the tree in 4MB-16MB chunks, dirtying everything and putting
-+ it into a transaction. We tell the allocator to allocate the blocks as far as possible towards one end of the
-+ logical device--the left (starting) end of the device if we are walking from left to right, the right end of the
-+ device if we are walking from right to left. We then make passes in alternating directions, and as we do this the
-+ device becomes sorted such that tree order and block number order fully correlate.
-+
-+ Resizing is done by shifting everything either all the way to the left or all the way
-+ to the right, and then reporting the last block.
-+*/
-+
-+/* RELOCATE DECISIONS: The code makes a decision to relocate in several places. This
-+ descibes the policy from the highest level:
-+
-+ The FLUSH_RELOCATE_THRESHOLD parameter: If we count this many consecutive nodes on the
-+ leaf level during flush-scan (right, left), then we unconditionally decide to relocate
-+ leaf nodes.
-+
-+ Otherwise, there are two contexts in which we make a decision to relocate:
-+
-+ 1. The REVERSE PARENT-FIRST context: Implemented in reverse_relocate_test().
-+ During the initial stages of flush, after scan-right completes, we want to ask the
-+ question: should we relocate this leaf node and thus dirty the parent node. Then if
-+ the node is a leftmost child its parent is its own parent-first preceder, thus we repeat
-+ the question at the next level up, and so on. In these cases we are moving in the
-+ reverse-parent first direction.
-+
-+ There is another case which is considered the reverse direction, which comes at the end
-+ of a twig in reverse_relocate_end_of_twig(). As we finish processing a twig we may
-+ reach a point where there is a clean twig to the right with a dirty leftmost child. In
-+ this case, we may wish to relocate the child by testing if it should be relocated
-+ relative to its parent.
-+
-+ 2. The FORWARD PARENT-FIRST context: Testing for forward relocation is done in
-+ allocate_znode. What distinguishes the forward parent-first case from the
-+ reverse-parent first case is that the preceder has already been allocated in the
-+ forward case, whereas in the reverse case we don't know what the preceder is until we
-+ finish "going in reverse". That simplifies the forward case considerably, and there we
-+ actually use the block allocator to determine whether, e.g., a block closer to the
-+ preceder is available.
-+*/
-+
-+/* SQUEEZE_LEFT_EDGE: Unimplemented idea for future consideration. The idea is, once we
-+ finish scan-left and find a starting point, if the parent's left neighbor is dirty then
-+ squeeze the parent's left neighbor and the parent. This may change the
-+ flush-starting-node's parent. Repeat until the child's parent is stable. If the child
-+ is a leftmost child, repeat this left-edge squeezing operation at the next level up.
-+ Note that we cannot allocate extents during this or they will be out of parent-first
-+ order. There is also some difficult coordinate maintenence issues. We can't do a tree
-+ search to find coordinates again (because we hold locks), we have to determine them
-+ from the two nodes being squeezed. Looks difficult, but has potential to increase
-+ space utilization. */

-+/* JNODE_FLUSH: MAIN ENTRY POINT */
-+/* This is the main entry point for flushing a jnode and its dirty neighborhood (dirty
-+ neighborhood is named "slum"). Jnode_flush() is called if reiser4 has to write dirty
-+ blocks to disk, it happens when Linux VM decides to reduce number of dirty pages or as
-+ a part of transaction commit.
-+
-+ Our objective here is to prep and flush the slum the jnode belongs to. We want to
-+ squish the slum together, and allocate the nodes in it as we squish because allocation
-+ of children affects squishing of parents.
-+
-+ The "argument" @node tells flush where to start. From there, flush finds the left edge
-+ of the slum, and calls squalloc (in which nodes are squeezed and allocated). To find a
-+ "better place" to start squalloc first we perform a flush_scan.
-+
-+ Flush-scanning may be performed in both left and right directions, but for different
-+ purposes. When scanning to the left, we are searching for a node that precedes a
-+ sequence of parent-first-ordered nodes which we will then flush in parent-first order.
-+ During flush-scanning, we also take the opportunity to count the number of consecutive
-+ leaf nodes. If this number is past some threshold (FLUSH_RELOCATE_THRESHOLD), then we
-+ make a decision to reallocate leaf nodes (thus favoring write-optimization).
-+
-+ Since the flush argument node can be anywhere in a sequence of dirty leaves, there may
-+ also be dirty nodes to the right of the argument. If the scan-left operation does not
-+ count at least FLUSH_RELOCATE_THRESHOLD nodes then we follow it with a right-scan
-+ operation to see whether there is, in fact, enough nodes to meet the relocate
-+ threshold. Each right- and left-scan operation uses a single flush_scan object.
-+
-+ After left-scan and possibly right-scan, we prepare a flush_position object with the
-+ starting flush point or parent coordinate, which was determined using scan-left.
-+
-+ Next we call the main flush routine, squalloc, which iterates along the
-+ leaf level, squeezing and allocating nodes (and placing them into the flush queue).
-+
-+ After squalloc returns we take extra steps to ensure that all the children
-+ of the final twig node are allocated--this involves repeating squalloc
-+ until we finish at a twig with no unallocated children.
-+
-+ Finally, we call flush_empty_queue to submit write-requests to disk. If we encounter
-+ any above-twig nodes during flush_empty_queue that still have unallocated children, we
-+ flush_unprep them.
-+
-+ Flush treats several "failure" cases as non-failures, essentially causing them to start
-+ over. E_DEADLOCK is one example. FIXME:(C) EINVAL, E_NO_NEIGHBOR, ENOENT: these should
-+ probably be handled properly rather than restarting, but there are a bunch of cases to
-+ audit.

-+/* This procedure implements the outer loop of the flush algorithm. To put this in
-+ context, here is the general list of steps taken by the flush routine as a whole:
-+
-+ 1. Scan-left
-+ 2. Scan-right (maybe)
-+ 3. Allocate initial flush position and its ancestors
-+ 4. <handle extents>
-+ 5. <squeeze and next position and its ancestors to-the-right,
-+ then update position to-the-right>
-+ 6. <repeat from #4 until flush is stopped>
-+
-+ This procedure implements the loop in steps 4 through 6 in the above listing.
-+
-+ Step 4: if the current flush position is an extent item (position on the twig level),
-+ it allocates the extent (allocate_extent_item_in_place) then shifts to the next
-+ coordinate. If the next coordinate's leftmost child needs flushprep, we will continue.
-+ If the next coordinate is an internal item, we descend back to the leaf level,
-+ otherwise we repeat a step #4 (labeled ALLOC_EXTENTS below). If the "next coordinate"
-+ brings us past the end of the twig level, then we call
-+ reverse_relocate_end_of_twig to possibly dirty the next (right) twig, prior to
-+ step #5 which moves to the right.
-+
-+ Step 5: calls squalloc_changed_ancestors, which initiates a recursive call up the
-+ tree to allocate any ancestors of the next-right flush position that are not also
-+ ancestors of the current position. Those ancestors (in top-down order) are the next in
-+ parent-first order. We squeeze adjacent nodes on the way up until the right node and
-+ current node share the same parent, then allocate on the way back down. Finally, this
-+ step sets the flush position to the next-right node. Then repeat steps 4 and 5.

-+ set in both scan objects. The limit parameter tells flush-scan when to stop.
-+
-+ Rapid scanning is used only during scan_left, where we are interested in finding the
-+ 'leftpoint' where we begin flushing. We are interested in stopping at the left child
-+ of a twig that does not have a dirty left neighbor. THIS IS A SPECIAL CASE. The
-+ problem is finding a way to flush only those nodes without unallocated children, and it
-+ is difficult to solve in the bottom-up flushing algorithm we are currently using. The
-+ problem can be solved by scanning left at every level as we go upward, but this would
-+ basically bring us back to using a top-down allocation strategy, which we already tried
-+ (see BK history from May 2002), and has a different set of problems. The top-down
-+ strategy makes avoiding unallocated children easier, but makes it difficult to
-+ propertly flush dirty children with clean parents that would otherwise stop the
-+ top-down flush, only later to dirty the parent once the children are flushed. So we
-+ solve the problem in the bottom-up algorithm with a special case for twigs and leaves
-+ only.
-+
-+ The first step in solving the problem is this rapid leftward scan. After we determine
-+ that there are at least enough nodes counted to qualify for FLUSH_RELOCATE_THRESHOLD we
-+ are no longer interested in the exact count, we are only interested in finding a the
-+ best place to start the flush. We could choose one of two possibilities:
-+
-+ 1. Stop at the leftmost child (of a twig) that does not have a dirty left neighbor.
-+ This requires checking one leaf per rapid-scan twig
-+
-+ 2. Stop at the leftmost child (of a twig) where there are no dirty children of the twig
-+ to the left. This requires checking possibly all of the in-memory children of each
-+ twig during the rapid scan.
-+
-+ For now we implement the first policy.

-+/* Jnode is entity used to track blocks with data and meta-data in reiser4.
-+
-+ In particular, jnodes are used to track transactional information
-+ associated with each block. Each znode contains jnode as ->zjnode field.
-+
-+ Jnode stands for either Josh or Journal node.
-+*/
-+
-+/*
-+ * Taxonomy.
-+ *
-+ * Jnode represents block containing data or meta-data. There are jnodes
-+ * for:
-+ *
-+ * unformatted blocks (jnodes proper). There are plans, however to
-+ * have a handle per extent unit rather than per each unformatted
-+ * block, because there are so many of them.
-+ *
-+ * For bitmaps. Each bitmap is actually represented by two jnodes--one
-+ * for working and another for "commit" data, together forming bnode.
-+ *
-+ * For io-heads. These are used by log writer.
-+ *
-+ * For formatted nodes (znode). See comment at the top of znode.c for
-+ * details specific to the formatted nodes (znodes).
-+ *
-+ * Node data.
-+ *
-+ * Jnode provides access to the data of node it represents. Data are
-+ * stored in a page. Page is kept in a page cache. This means, that jnodes
-+ * are highly interconnected with page cache and VM internals.
-+ *
-+ * jnode has a pointer to page (->pg) containing its data. Pointer to data
-+ * themselves is cached in ->data field to avoid frequent calls to
-+ * page_address().
-+ *
-+ * jnode and page are attached to each other by jnode_attach_page(). This
-+ * function places pointer to jnode in set_page_private(), sets PG_private
-+ * flag and increments page counter.
-+ *
-+ * Opposite operation is performed by page_clear_jnode().
-+ *
-+ * jnode->pg is protected by jnode spin lock, and page->private is
-+ * protected by page lock. See comment at the top of page_cache.c for
-+ * more.
-+ *
-+ * page can be detached from jnode for two reasons:
-+ *
-+ * . jnode is removed from a tree (file is truncated, of formatted
-+ * node is removed by balancing).
-+ *
-+ * . during memory pressure, VM calls ->releasepage() method
-+ * (reiser4_releasepage()) to evict page from memory.
-+ *
-+ * (there, of course, is also umount, but this is special case we are not
-+ * concerned with here).
-+ *
-+ * To protect jnode page from eviction, one calls jload() function that
-+ * "pins" page in memory (loading it if necessary), increments
-+ * jnode->d_count, and kmap()s page. Page is unpinned through call to
-+ * jrelse().
-+ *
-+ * Jnode life cycle.
-+ *
-+ * jnode is created, placed in hash table, and, optionally, in per-inode
-+ * radix tree. Page can be attached to jnode, pinned, released, etc.
-+ *
-+ * When jnode is captured into atom its reference counter is
-+ * increased. While being part of an atom, jnode can be "early
-+ * flushed". This means that as part of flush procedure, jnode is placed
-+ * into "relocate set", and its page is submitted to the disk. After io
-+ * completes, page can be detached, then loaded again, re-dirtied, etc.
-+ *
-+ * Thread acquired reference to jnode by calling jref() and releases it by
-+ * jput(). When last reference is removed, jnode is still retained in
-+ * memory (cached) if it has page attached, _unless_ it is scheduled for
-+ * destruction (has JNODE_HEARD_BANSHEE bit set).
-+ *
-+ * Tree read-write lock was used as "existential" lock for jnodes. That is,
-+ * jnode->x_count could be changed from 0 to 1 only under tree write lock,
-+ * that is, tree lock protected unreferenced jnodes stored in the hash
-+ * table, from recycling.
-+ *
-+ * This resulted in high contention on tree lock, because jref()/jput() is
-+ * frequent operation. To ameliorate this problem, RCU is used: when jput()
-+ * is just about to release last reference on jnode it sets JNODE_RIP bit
-+ * on it, and then proceed with jnode destruction (removing jnode from hash
-+ * table, cbk_cache, detaching page, etc.). All places that change jnode
-+ * reference counter from 0 to 1 (jlookup(), zlook(), zget(), and
-+ * cbk_cache_scan_slots()) check for JNODE_RIP bit (this is done by
-+ * jnode_rip_check() function), and pretend that nothing was found in hash
-+ * table if bit is set.
-+ *
-+ * jput defers actual return of jnode into slab cache to some later time
-+ * (by call_rcu()), this guarantees that other threads can safely continue
-+ * working with JNODE_RIP-ped jnode.
-+ *

-+ Jnode is the "base class" of other nodes in reiser4. It is also happens to
-+ be exactly the node we use for unformatted tree nodes.
-+
-+ Jnode provides following basic functionality:
-+
-+ . reference counting and indexing.
-+
-+ . integration with page cache. Jnode has ->pg reference to which page can
-+ be attached.
-+
-+ . interface to transaction manager. It is jnode that is kept in transaction
-+ manager lists, attached to atoms, etc. (NOTE-NIKITA one may argue that this
-+ means, there should be special type of jnode for inode.)
-+
-+ Locking:
-+
-+ Spin lock: the following fields are protected by the per-jnode spin lock:
-+
-+ ->state
-+ ->atom
-+ ->capture_link
-+
-+ Following fields are protected by the global tree lock:
-+
-+ ->link
-+ ->key.z (content of ->key.z is only changed in znode_rehash())
-+ ->key.j
-+
-+ Atomic counters
-+
-+ ->x_count
-+ ->d_count
-+
-+ ->pg, and ->data are protected by spin lock for unused jnode and are
-+ immutable for used jnode (one for which fs/reiser4/vfs_ops.c:releasable()
-+ is false).
-+
-+ ->tree is immutable after creation
-+
-+ Unclear
-+
-+ ->blocknr: should be under jnode spin-lock, but current interface is based
-+ on passing of block address.
-+
-+ If you ever need to spin lock two nodes at once, do this in "natural"
-+ memory order: lock znode with lower address first. (See lock_two_nodes().)
-+
-+ Invariants involving this data-type:
-+

-+/* Key assignment policy implementation */
-+
-+/*
-+ * In reiser4 every piece of file system data and meta-data has a key. Keys
-+ * are used to store information in and retrieve it from reiser4 internal
-+ * tree. In addition to this, keys define _ordering_ of all file system
-+ * information: things having close keys are placed into the same or
-+ * neighboring (in the tree order) nodes of the tree. As our block allocator
-+ * tries to respect tree order (see flush.c), keys also define order in which
-+ * things are laid out on the disk, and hence, affect performance directly.
-+ *
-+ * Obviously, assignment of keys to data and meta-data should be consistent
-+ * across whole file system. Algorithm that calculates a key for a given piece
-+ * of data or meta-data is referred to as "key assignment".
-+ *
-+ * Key assignment is too expensive to be implemented as a plugin (that is,
-+ * with an ability to support different key assignment schemas in the same
-+ * compiled kernel image). As a compromise, all key-assignment functions and
-+ * data-structures are collected in this single file, so that modifications to
-+ * key assignment algorithm can be localized. Additional changes may be
-+ * required in key.[ch].
-+ *
-+ * Current default reiser4 key assignment algorithm is dubbed "Plan A". As one
-+ * may guess, there is "Plan B" too.
-+ *
-+ */
-+
-+/*
-+ * Additional complication with key assignment implementation is a requirement
-+ * to support different key length.

-+/* Information from which key of file stat-data can be uniquely
-+ restored. This depends on key assignment policy for
-+ stat-data. Currently it's enough to store object id and locality id
-+ (60+60==120) bits, because minor packing locality and offset of
-+ stat-data key are always known constants: KEY_SD_MINOR and 0
-+ respectively. For simplicity 4 bits are wasted in each id, and just
-+ two 64 bit integers are stored.
-+
-+ This field has to be byte-aligned, because we don't want to waste
-+ space in directory entries. There is another side of a coin of
-+ course: we waste CPU and bus bandwidth in stead, by copying data back
-+ and forth.
-+
-+ Next optimization: &obj_key_id is mainly used to address stat data from
-+ directory entries. Under the assumption that majority of files only have
-+ only name (one hard link) from *the* parent directory it seems reasonable
-+ to only store objectid of stat data and take its locality from key of
-+ directory item.
-+
-+ This requires some flag to be added to the &obj_key_id to distinguish
-+ between these two cases. Remaining bits in flag byte are then asking to be
-+ used to store file type.

-+/* Traditional deadlock avoidance is achieved by acquiring all locks in a single
-+ order. V4 balances the tree from the bottom up, and searches the tree from
-+ the top down, and that is really the way we want it, so tradition won't work
-+ for us.
-+
-+ Instead we have two lock orderings, a high priority lock ordering, and a low
-+ priority lock ordering. Each node in the tree has a lock in its znode.
-+
-+ Suppose we have a set of processes which lock (R/W) tree nodes. Each process
-+ has a set (maybe empty) of already locked nodes ("process locked set"). Each
-+ process may have a pending lock request to a node locked by another process.
-+ Note: we lock and unlock, but do not transfer locks: it is possible
-+ transferring locks instead would save some bus locking....
-+
-+ Deadlock occurs when we have a loop constructed from process locked sets and
-+ lock request vectors.
-+
-+ NOTE: The reiser4 "tree" is a tree on disk, but its cached representation in
-+ memory is extended with "znodes" with which we connect nodes with their left
-+ and right neighbors using sibling pointers stored in the znodes. When we
-+ perform balancing operations we often go from left to right and from right to
-+ left.

-+ +---------P2---------+
-+ |+--+ +--+|
-+ ||N2| -------- |N4||
-+ |+--+ +--+|
-+ +--------------------+
-+
-+ We solve this by ensuring that only low priority processes lock in top to
-+ bottom order and from right to left, and high priority processes lock from
-+ bottom to top and left to right.
-+
-+ ZAM-FIXME-HANS: order not just node locks in this way, order atom locks, and
-+ kill those damn busy loops.
-+ ANSWER(ZAM): atom locks (which are introduced by ASTAGE_CAPTURE_WAIT atom
-+ stage) cannot be ordered that way. There are no rules what nodes can belong
-+ to the atom and what nodes cannot. We cannot define what is right or left
-+ direction, what is top or bottom. We can take immediate parent or side
-+ neighbor of one node, but nobody guarantees that, say, left neighbor node is
-+ not a far right neighbor for other nodes from the same atom. It breaks
-+ deadlock avoidance rules and hi-low priority locking cannot be applied for
-+ atom locks.
-+
-+ How does it help to avoid deadlocks ?
-+
-+ Suppose we have a deadlock with n processes. Processes from one priority
-+ class never deadlock because they take locks in one consistent
-+ order.
-+
-+ So, any possible deadlock loop must have low priority as well as high
-+ priority processes. There are no other lock priority levels except low and
-+ high. We know that any deadlock loop contains at least one node locked by a
-+ low priority process and requested by a high priority process. If this
-+ situation is caught and resolved it is sufficient to avoid deadlocks.
-+
-+ V4 DEADLOCK PREVENTION ALGORITHM IMPLEMENTATION.
-+
-+ The deadlock prevention algorithm is based on comparing
-+ priorities of node owners (processes which keep znode locked) and
-+ requesters (processes which want to acquire a lock on znode). We
-+ implement a scheme where low-priority owners yield locks to
-+ high-priority requesters. We created a signal passing system that
-+ is used to ask low-priority processes to yield one or more locked
-+ znodes.
-+
-+ The condition when a znode needs to change its owners is described by the
-+ following formula:
-+
-+ #############################################
-+ # #
-+ # (number of high-priority requesters) > 0 #
-+ # AND #
-+ # (numbers of high-priority owners) == 0 #
-+ # #
-+ #############################################
-+
-+ Note that a low-priority process delays node releasing if another
-+ high-priority process owns this node. So, slightly more strictly speaking,
-+ to have a deadlock capable cycle you must have a loop in which a high
-+ priority process is waiting on a low priority process to yield a node, which
-+ is slightly different from saying a high priority process is waiting on a
-+ node owned by a low priority process.
-+
-+ It is enough to avoid deadlocks if we prevent any low-priority process from
-+ falling asleep if its locked set contains a node which satisfies the
-+ deadlock condition.
-+
-+ That condition is implicitly or explicitly checked in all places where new
-+ high-priority requests may be added or removed from node request queue or
-+ high-priority process takes or releases a lock on node. The main
-+ goal of these checks is to never lose the moment when node becomes "has
-+ wrong owners" and send "must-yield-this-lock" signals to its low-pri owners
-+ at that time.
-+
-+ The information about received signals is stored in the per-process
-+ structure (lock stack) and analyzed before a low-priority process goes to
-+ sleep but after a "fast" attempt to lock a node fails. Any signal wakes
-+ sleeping process up and forces him to re-check lock status and received
-+ signal info. If "must-yield-this-lock" signals were received the locking
-+ primitive (longterm_lock_znode()) fails with -E_DEADLOCK error code.
-+
-+ V4 LOCKING DRAWBACKS
-+
-+ If we have already balanced on one level, and we are propagating our changes
-+ upward to a higher level, it could be very messy to surrender all locks on
-+ the lower level because we put so much computational work into it, and
-+ reverting them to their state before they were locked might be very complex.
-+ We also don't want to acquire all locks before performing balancing because
-+ that would either be almost as much work as the balancing, or it would be
-+ too conservative and lock too much. We want balancing to be done only at
-+ high priority. Yet, we might want to go to the left one node and use some
-+ of its empty space... So we make one attempt at getting the node to the left
-+ using try_lock, and if it fails we do without it, because we didn't really
-+ need it, it was only a nice to have.
-+
-+ LOCK STRUCTURES DESCRIPTION
-+
-+ The following data structures are used in the reiser4 locking
-+ implementation:
-+
-+ All fields related to long-term locking are stored in znode->lock.
-+
-+ The lock stack is a per thread object. It owns all znodes locked by the
-+ thread. One znode may be locked by several threads in case of read lock or
-+ one znode may be write locked by one thread several times. The special link
-+ objects (lock handles) support n<->m relation between znodes and lock
-+ owners.
-+
-+ <Thread 1> <Thread 2>
-+
-+ +---------+ +---------+
-+ | LS1 | | LS2 |
-+ +---------+ +---------+
-+ ^ ^
-+ |---------------+ +----------+
-+ v v v v
-+ +---------+ +---------+ +---------+ +---------+
-+ | LH1 | | LH2 | | LH3 | | LH4 |
-+ +---------+ +---------+ +---------+ +---------+
-+ ^ ^ ^ ^
-+ | +------------+ |
-+ v v v
-+ +---------+ +---------+ +---------+
-+ | Z1 | | Z2 | | Z3 |
-+ +---------+ +---------+ +---------+
-+
-+ Thread 1 locked znodes Z1 and Z2, thread 2 locked znodes Z2 and Z3. The
-+ picture above shows that lock stack LS1 has a list of 2 lock handles LH1 and
-+ LH2, lock stack LS2 has a list with lock handles LH3 and LH4 on it. Znode
-+ Z1 is locked by only one thread, znode has only one lock handle LH1 on its
-+ list, similar situation is for Z3 which is locked by the thread 2 only. Z2
-+ is locked (for read) twice by different threads and two lock handles are on
-+ its list. Each lock handle represents a single relation of a locking of a
-+ znode by a thread. Locking of a znode is an establishing of a locking
-+ relation between the lock stack and the znode by adding of a new lock handle
-+ to a list of lock handles, the lock stack. The lock stack links all lock
-+ handles for all znodes locked by the lock stack. The znode list groups all
-+ lock handles for all locks stacks which locked the znode.
-+
-+ Yet another relation may exist between znode and lock owners. If lock
-+ procedure cannot immediately take lock on an object it adds the lock owner
-+ on special `requestors' list belongs to znode. That list represents a
-+ queue of pending lock requests. Because one lock owner may request only
-+ only one lock object at a time, it is a 1->n relation between lock objects
-+ and a lock owner implemented as it is described above. Full information
-+ (priority, pointers to lock and link objects) about each lock request is
-+ stored in lock owner structure in `request' field.
-+
-+ SHORT_TERM LOCKING
-+
-+ This is a list of primitive operations over lock stacks / lock handles /
-+ znodes and locking descriptions for them.
-+
-+ 1. locking / unlocking which is done by two list insertion/deletion, one
-+ to/from znode's list of lock handles, another one is to/from lock stack's
-+ list of lock handles. The first insertion is protected by
-+ znode->lock.guard spinlock. The list owned by the lock stack can be
-+ modified only by thread who owns the lock stack and nobody else can
-+ modify/read it. There is nothing to be protected by a spinlock or
-+ something else.
-+
-+ 2. adding/removing a lock request to/from znode requesters list. The rule is
-+ that znode->lock.guard spinlock should be taken for this.
-+
-+ 3. we can traverse list of lock handles and use references to lock stacks who
-+ locked given znode if znode->lock.guard spinlock is taken.
-+
-+ 4. If a lock stack is associated with a znode as a lock requestor or lock
-+ owner its existence is guaranteed by znode->lock.guard spinlock. Some its
-+ (lock stack's) fields should be protected from being accessed in parallel
-+ by two or more threads. Please look at lock_stack structure definition
-+ for the info how those fields are protected. */
-+
-+/* Znode lock and capturing intertwining. */
-+/* In current implementation we capture formatted nodes before locking
-+ them. Take a look on longterm lock znode, try_capture() request precedes
-+ locking requests. The longterm_lock_znode function unconditionally captures
-+ znode before even checking of locking conditions.
-+
-+ Another variant is to capture znode after locking it. It was not tested, but
-+ at least one deadlock condition is supposed to be there. One thread has
-+ locked a znode (Node-1) and calls try_capture() for it. Try_capture() sleeps
-+ because znode's atom has CAPTURE_WAIT state. Second thread is a flushing
-+ thread, its current atom is the atom Node-1 belongs to. Second thread wants
-+ to lock Node-1 and sleeps because Node-1 is locked by the first thread. The
-+ described situation is a deadlock. */

-+/* Memory pressure hooks. Fake inodes handling. */
-+/* We store all file system meta data (and data, of course) in the page cache.
-+
-+ What does this mean? In stead of using bread/brelse we create special
-+ "fake" inode (one per super block) and store content of formatted nodes
-+ into pages bound to this inode in the page cache. In newer kernels bread()
-+ already uses inode attached to block device (bd_inode). Advantage of having
-+ our own fake inode is that we can install appropriate methods in its
-+ address_space operations. Such methods are called by VM on memory pressure
-+ (or during background page flushing) and we can use them to react
-+ appropriately.
-+
-+ In initial version we only support one block per page. Support for multiple
-+ blocks per page is complicated by relocation.
-+
-+ To each page, used by reiser4, jnode is attached. jnode is analogous to
-+ buffer head. Difference is that jnode is bound to the page permanently:
-+ jnode cannot be removed from memory until its backing page is.
-+
-+ jnode contain pointer to page (->pg field) and page contain pointer to
-+ jnode in ->private field. Pointer from jnode to page is protected to by
-+ jnode's spinlock and pointer from page to jnode is protected by page lock
-+ (PG_locked bit). Lock ordering is: first take page lock, then jnode spin
-+ lock. To go into reverse direction use jnode_lock_page() function that uses
-+ standard try-lock-and-release device.
-+
-+ Properties:
-+
-+ 1. when jnode-to-page mapping is established (by jnode_attach_page()), page
-+ reference counter is increased.
-+
-+ 2. when jnode-to-page mapping is destroyed (by jnode_detach_page() and
-+ page_detach_jnode()), page reference counter is decreased.
-+
-+ 3. on jload() reference counter on jnode page is increased, page is
-+ kmapped and `referenced'.
-+
-+ 4. on jrelse() inverse operations are performed.
-+
-+ 5. kmapping/kunmapping of unformatted pages is done by read/write methods.
-+
-+ DEADLOCKS RELATED TO MEMORY PRESSURE. [OUTDATED. Only interesting
-+ historically.]
-+
-+ [In the following discussion, `lock' invariably means long term lock on
-+ znode.] (What about page locks?)
-+
-+ There is some special class of deadlock possibilities related to memory
-+ pressure. Locks acquired by other reiser4 threads are accounted for in
-+ deadlock prevention mechanism (lock.c), but when ->vm_writeback() is
-+ invoked additional hidden arc is added to the locking graph: thread that
-+ tries to allocate memory waits for ->vm_writeback() to finish. If this
-+ thread keeps lock and ->vm_writeback() tries to acquire this lock, deadlock
-+ prevention is useless.
-+
-+ Another related problem is possibility for ->vm_writeback() to run out of
-+ memory itself. This is not a problem for ext2 and friends, because their
-+ ->vm_writeback() don't allocate much memory, but reiser4 flush is
-+ definitely able to allocate huge amounts of memory.
-+
-+ It seems that there is no reliable way to cope with the problems above. In
-+ stead it was decided that ->vm_writeback() (as invoked in the kswapd
-+ context) wouldn't perform any flushing itself, but rather should just wake
-+ up some auxiliary thread dedicated for this purpose (or, the same thread
-+ that does periodic commit of old atoms (ktxnmgrd.c)).
-+
-+ Details:
-+
-+ 1. Page is called `reclaimable' against particular reiser4 mount F if this
-+ page can be ultimately released by try_to_free_pages() under presumptions
-+ that:
-+
-+ a. ->vm_writeback() for F is no-op, and
-+
-+ b. none of the threads accessing F are making any progress, and
-+
-+ c. other reiser4 mounts obey the same memory reservation protocol as F
-+ (described below).
-+
-+ For example, clean un-pinned page, or page occupied by ext2 data are
-+ reclaimable against any reiser4 mount.
-+
-+ When there is more than one reiser4 mount in a system, condition (c) makes
-+ reclaim-ability not easily verifiable beyond trivial cases mentioned above.
-+
-+ THIS COMMENT IS VALID FOR "MANY BLOCKS ON PAGE" CASE
-+
-+ Fake inode is used to bound formatted nodes and each node is indexed within
-+ fake inode by its block number. If block size of smaller than page size, it
-+ may so happen that block mapped to the page with formatted node is occupied
-+ by unformatted node or is unallocated. This lead to some complications,
-+ because flushing whole page can lead to an incorrect overwrite of
-+ unformatted node that is moreover, can be cached in some other place as
-+ part of the file body. To avoid this, buffers for unformatted nodes are
-+ never marked dirty. Also pages in the fake are never marked dirty. This
-+ rules out usage of ->writepage() as memory pressure hook. In stead
-+ ->releasepage() is used.
-+
-+ Josh is concerned that page->buffer is going to die. This should not pose
-+ significant problem though, because we need to add some data structures to
-+ the page anyway (jnode) and all necessary book keeping can be put there.
-+
-+*/
-+
-+/* Life cycle of pages/nodes.
-+
-+ jnode contains reference to page and page contains reference back to
-+ jnode. This reference is counted in page ->count. Thus, page bound to jnode
-+ cannot be released back into free pool.
-+
-+ 1. Formatted nodes.
-+
-+ 1. formatted node is represented by znode. When new znode is created its
-+ ->pg pointer is NULL initially.
-+
-+ 2. when node content is loaded into znode (by call to zload()) for the
-+ first time following happens (in call to ->read_node() or
-+ ->allocate_node()):
-+
-+ 1. new page is added to the page cache.
-+
-+ 2. this page is attached to znode and its ->count is increased.
-+
-+ 3. page is kmapped.
-+
-+ 3. if more calls to zload() follow (without corresponding zrelses), page
-+ counter is left intact and in its stead ->d_count is increased in znode.
-+
-+ 4. each call to zrelse decreases ->d_count. When ->d_count drops to zero
-+ ->release_node() is called and page is kunmapped as result.
-+
-+ 5. at some moment node can be captured by a transaction. Its ->x_count
-+ is then increased by transaction manager.
-+
-+ 6. if node is removed from the tree (empty node with JNODE_HEARD_BANSHEE
-+ bit set) following will happen (also see comment at the top of znode.c):
-+
-+ 1. when last lock is released, node will be uncaptured from
-+ transaction. This released reference that transaction manager acquired
-+ at the step 5.
-+
-+ 2. when last reference is released, zput() detects that node is
-+ actually deleted and calls ->delete_node()
-+ operation. page_cache_delete_node() implementation detaches jnode from
-+ page and releases page.
-+
-+ 7. otherwise (node wasn't removed from the tree), last reference to
-+ znode will be released after transaction manager committed transaction
-+ node was in. This implies squallocing of this node (see
-+ flush.c). Nothing special happens at this point. Znode is still in the
-+ hash table and page is still attached to it.
-+
-+ 8. znode is actually removed from the memory because of the memory
-+ pressure, or during umount (znodes_tree_done()). Anyway, znode is
-+ removed by the call to zdrop(). At this moment, page is detached from
-+ znode and removed from the inode address space.

-+
-+ A: because vfs calls fs's truncate after it has called truncate_inode_pages to get rid of pages

-+ extents which do not have jnodes. Flush code does not expect that. Solution of this problem is

-+ which calls truncate_inode_pages and fs's truncate in case when size of file changes) - it seems
-+ reasonable to have reiser4_setattr which will take care of removing pages, jnodes and extents
-+ simultaneously in case of truncate.
-+ Q: do you think implementing truncate using setattr is ugly,

-+/* Suppose you want to conveniently read and write a large variety of small files conveniently within a single emacs
-+ buffer, without having a separate buffer for each 8 byte or so file. Inverts are the way to do that. An invert
-+ provides you with the contents of a set of subfiles plus its own contents. It is a file which inherits other files
-+ when you read it, and allows you to write to it and through it to the files that it inherits from. In order for it
-+ to know which subfiles each part of your write should go into, there must be delimiters indicating that. It tries to
-+ make that easy for you by providing those delimiters in what you read from it.
-+
-+ When you read it, an invert performs an inverted assignment. Instead of taking an assignment command and writing a
-+ bunch of files, it takes a bunch of files and composes an assignment command for you to read from it that if executed
-+ would create those files. But which files? Well, that must be specified in the body of the invert using a special
-+ syntax, and that specification is called the invert of the assignment.
-+
-+ When written to, an invert performs the assignment command that is written
-+ to it, and modifies its own body to contain the invert of that
-+ assignment.
-+
-+ In other words, writing to an invert file what you have read from it
-+ is the identity operation.
-+
-+ Malformed assignments cause write errors. Partial writes are not
-+ supported in v4.0, but will be.
-+
-+ Example:
-+
-+ If an invert contains:
-+
-+ /filenameA/<>+"(some text stored in the invert)+/filenameB/<>
-+
-+======================
-+Each element in this definition should be an invert, and all files
-+should be called recursively - too. This is bad. If one of the
-+included files in not a regular or invert file, then we can't read
-+main file.
-+
-+I think to make it is possible easier:
-+
-+internal structure of invert file should be like symlink file. But
-+read and write method should be explitely indicated in i/o operation..
-+
-+By default we read and write (if probably) as symlink and if we
-+specify ..invert at reading time that too we can specify it at write time.
-+
-+example:
-+/my_invert_file/..invert<- ( (/filenameA<-"(The contents of filenameA))+"(some text stored in the invert)+(/filenameB<-"(The contents of filenameB) ) )
-+will create /my_invert_file as invert, and will creat /filenameA and /filenameB with specified body.
-+
-+read of /my_invert_file/..invert will be
-+/filenameA<-"(The contents of filenameA)+"(some text stored in the invert)+/filenameB<-"(The contents of filenameB)
-+
-+but read of /my_invert_file/ will be
-+The contents of filenameAsome text stored in the invertThe contents of filenameB
-+
-+we also can creat this file as
-+/my_invert_file/<-/filenameA+"(some text stored in the invert)+/filenameB
-+will create /my_invert_file , and use existing files /filenameA and /filenameB.
-+
-+and when we will read it will be as previously invert file.
-+
-+This is correct?
-+
-+ vv
-+DEMIDOV-FIXME-HANS:
-+
-+Maybe you are right, but then you must disable writes to /my_invert_file/ and only allow writes to /my_invert_file/..invert
-+
-+Do you agree? Discuss it on reiserfs-list....
-+
-+-Hans
-+=======================
-+
-+ Then a read will return:
-+
-+ /filenameA<-"(The contents of filenameA)+"(some text stored in the invert)+/filenameB<-"(The contents of filenameB)
-+
-+ and a write of the line above to the invert will set the contents of
-+ the invert and filenameA and filenameB to their original values.
-+
-+ Note that the contents of an invert have no influence on the effect
-+ of a write unless the write is a partial write (and a write of a
-+ shorter file without using truncate first is a partial write).
-+
-+ truncate() has no effect on filenameA and filenameB, it merely
-+ resets the value of the invert.
-+
-+ Writes to subfiles via the invert are implemented by preceding them
-+ with truncates.
-+
-+ Parse failures cause write failures.
-+
-+ Questions to ponder: should the invert be acted on prior to file
-+ close when writing to an open filedescriptor?
-+
-+ Example:
-+
-+ If an invert contains:
-+
-+ "(This text and a pair of quotes are all that is here.)
-+
-+Then a read will return:
-+
-+ "(This text and a pair of quotes are all that is here.)
-+
-+*/
-+
-+/* OPEN method places a struct file in memory associated with invert body
-+ and returns something like file descriptor to the user for the future access
-+ to the invert file.
-+ During opening we parse the body of invert and get a list of the 'entryes'
-+ (that describes all its subfiles) and place pointer on the first struct in
-+ reiserfs-specific part of invert inode (arbitrary decision).
-+
-+ Each subfile is described by the struct inv_entry that has a pointer @sd on
-+ in-core based stat-data and a pointer on struct file @f (if we find that the
-+ subfile uses more then one unformated node (arbitrary decision), we load
-+ struct file in memory, otherwise we load base stat-data (and maybe 1-2 bytes
-+ of some other information we need)
-+
-+ Since READ and WRITE methods for inverts were formulated in assignment
-+ language, they don't contain arguments 'size' and 'offset' that make sense
-+ only in ordinary read/write methods.
-+
-+ READ method is a combination of two methods:
-+ 1) ordinary read method (with offset=0, lenght = @f->...->i_size) for entries
-+ with @f != 0, this method uses pointer on struct file as an argument
-+ 2) read method for inode-less files with @sd != 0, this method uses
-+ in-core based stat-data instead struct file as an argument.
-+ in the first case we don't use pagecache, just copy data that we got after
-+ cbk() into userspace.
-+
-+ WRITE method for invert files is more complex.
-+ Besides declared WRITE-interface in assignment languageb above we need
-+ to have an opportunity to edit unwrapped body of invert file with some
-+ text editor, it means we need GENERIC WRITE METHOD for invert file:
-+
-+ my_invert_file/..invert <- "string"
-+
-+ this method parses "string" and looks for correct subfile signatures, also
-+ the parsing process splits this "string" on the set of flows in accordance
-+ with the set of subfiles specified by this signarure.
-+ The found list of signatures #S is compared with the opened one #I of invert
-+ file. If it doesn't have this one (#I==0, it will be so for instance if we
-+ have just create this invert file) the write method assignes found signature
-+ (#I=#S;) to the invert file. Then if #I==#S, generic write method splits
-+ itself to the some write methods for ordinary or light-weight, or call itself
-+ recursively for invert files with corresponding flows.
-+ I am not sure, but the list of signatures looks like what mr.Demidov means
-+ by 'delimiters'.
-+
-+ The cases when #S<#I (#I<#S) (in the sense of set-theory) are also available
-+ and cause delete (create new) subfiles (arbitrary decision - it may looks
-+ too complex, but this interface will be the completest). The order of entries
-+ of list #S (#I) and inherited order on #I (#S) must coincide.
-+ The other parsing results give malformed signature that aborts READ method
-+ and releases all resources.
-+
-+ Format of subfile (entry) signature:
-+
-+ "START_MAGIC"<>(TYPE="...",LOOKUP_ARG="...")SUBFILE_BODY"END_MAGIC"
-+
-+ Legend:
-+
-+ START_MAGIC - keyword indicates the start of subfile signature;
-+
-+ <> indicates the start of 'subfile metadata', that is the pair
-+ (TYPE="...",LOOKUP_ARG="...") in parenthesis separated by comma.
-+
-+ TYPE - the string "type" indicates the start of one of the three words:
-+ - ORDINARY_FILE,
-+ - LIGHT_WEIGHT_FILE,
-+ - INVERT_FILE;
-+
-+ LOOKUP_ARG - lookup argument depends on previous type:
-+ */
-+
-+ /************************************************************/
-+ /* TYPE * LOOKUP ARGUMENT */
-+ /************************************************************/
-+ /* LIGH_WEIGHT_FILE * stat-data key */
-+ /************************************************************/
-+ /* ORDINARY_FILE * filename */
-+ /************************************************************/
-+ /* INVERT_FILE * filename */
-+ /************************************************************/
-+
-+ /* where:
-+ *stat-data key - the string contains stat data key of this subfile, it will be
-+ passed to fast-access lookup method for light-weight files;
-+ *filename - pathname of this subfile, iyt well be passed to VFS lookup methods
-+ for ordinary and invert files;
-+
-+ SUBFILE_BODY - data of this subfile (it will go to the flow)
-+ END_MAGIC - the keyword indicates the end of subfile signature.
-+
-+ The other simbols inside the signature interpreted as 'unformatted content',
-+ which is available with VFS's read_link() (arbitraruy decision).
-+
-+ NOTE: Parse method for a body of invert file uses mentioned signatures _without_
-+ subfile bodies.
-+
-+ Now the only unclear thing is WRITE in regular light-weight subfile A that we
-+ can describe only in assignment language:
-+
-+ A <- "some_string"
-+
-+ I guess we don't want to change stat-data and body items of file A
-+ if this file exist, and size(A) != size("some_string") because this operation is
-+ expencive, so we only do the partial write if size(A) > size("some_string")
-+ and do truncate of the "some_string", and then do A <- "truncated string", if
-+ size(A) < size("some_string"). This decision is also arbitrary..

-+/* Symfiles are a generalization of Unix symlinks.
-+
-+ A symfile when read behaves as though you took its contents and
-+ substituted them into the reiser4 naming system as the right hand side
-+ of an assignment, and then read that which you had assigned to it.
-+
-+ A key issue for symfiles is how to implement writes through to
-+ subfiles. In general, one must have some method of determining what
-+ of that which is written to the symfile is written to what subfile.
-+ This can be done by use of custom plugin methods written by users, or
-+ by using a few general methods we provide for those willing to endure
-+ the insertion of delimiters into what is read.
-+
-+ Writing to symfiles without delimiters to denote what is written to
-+ what subfile is not supported by any plugins we provide in this
-+ release. Our most sophisticated support for writes is that embodied
-+ by the invert plugin (see invert.c).
-+
-+ A read only version of the /etc/passwd file might be
-+ constructed as a symfile whose contents are as follows:
-+
-+ /etc/passwd/userlines/*
-+
-+ or
-+
-+ /etc/passwd/userlines/demidov+/etc/passwd/userlines/edward+/etc/passwd/userlines/reiser+/etc/passwd/userlines/root
-+
-+ or
-+
-+ /etc/passwd/userlines/(demidov+edward+reiser+root)
-+
-+ A symfile with contents
-+
-+ /filenameA+"(some text stored in the uninvertable symfile)+/filenameB
-+
-+ will return when read
-+
-+ The contents of filenameAsome text stored in the uninvertable symfileThe contents of filenameB
-+
-+ and write of what has been read will not be possible to implement as
-+ an identity operation because there are no delimiters denoting the
-+ boundaries of what is to be written to what subfile.
-+
-+ Note that one could make this a read/write symfile if one specified
-+ delimiters, and the write method understood those delimiters delimited
-+ what was written to subfiles.
-+
-+ So, specifying the symfile in a manner that allows writes:
-+
-+ /etc/passwd/userlines/demidov+"(
-+ )+/etc/passwd/userlines/edward+"(
-+ )+/etc/passwd/userlines/reiser+"(
-+ )+/etc/passwd/userlines/root+"(
-+ )
-+
-+ or
-+
-+ /etc/passwd/userlines/(demidov+"(
-+ )+edward+"(
-+ )+reiser+"(
-+ )+root+"(
-+ ))
-+
-+ and the file demidov might be specified as:
-+
-+ /etc/passwd/userlines/demidov/username+"(:)+/etc/passwd/userlines/demidov/password+"(:)+/etc/passwd/userlines/demidov/userid+"(:)+/etc/passwd/userlines/demidov/groupid+"(:)+/etc/passwd/userlines/demidov/gecos+"(:)+/etc/passwd/userlines/demidov/home+"(:)+/etc/passwd/userlines/demidov/shell
-+
-+ or
-+
-+ /etc/passwd/userlines/demidov/(username+"(:)+password+"(:)+userid+"(:)+groupid+"(:)+gecos+"(:)+home+"(:)+shell)
-+
-+ Notice that if the file demidov has a carriage return in it, the
-+ parsing fails, but then if you put carriage returns in the wrong place
-+ in a normal /etc/passwd file it breaks things also.
-+
-+ Note that it is forbidden to have no text between two interpolations
-+ if one wants to be able to define what parts of a write go to what
-+ subfiles referenced in an interpolation.
-+
-+ If one wants to be able to add new lines by writing to the file, one
-+ must either write a custom plugin for /etc/passwd that knows how to
-+ name an added line, or one must use an invert, or one must use a more
-+ sophisticated symfile syntax that we are not planning to write for
-+ version 4.0.

-+ * STATELESS READDIR
-+ *
-+ * readdir support in reiser4 relies on ability to update readdir_pos embedded
-+ * into reiser4_file_fsdata on each directory modification (name insertion and
-+ * removal), see readdir_common() function below. This obviously doesn't work
-+ * when reiser4 is accessed over NFS, because NFS doesn't keep any state
-+ * across client READDIR requests for the same directory.
-+ *
-+ * To address this we maintain a "pool" of detached reiser4_file_fsdata
-+ * (d_cursor). Whenever NFS readdir request comes, we detect this, and try to
-+ * find detached reiser4_file_fsdata corresponding to previous readdir
-+ * request. In other words, additional state is maintained on the
-+ * server. (This is somewhat contrary to the design goals of NFS protocol.)
-+ *
-+ * To efficiently detect when our ->readdir() method is called by NFS server,
-+ * dentry is marked as "stateless" in reiser4_decode_fh() (this is checked by
-+ * file_is_stateless() function).
-+ *
-+ * To find out d_cursor in the pool, we encode client id (cid) in the highest
-+ * bits of NFS readdir cookie: when first readdir request comes to the given
-+ * directory from the given client, cookie is set to 0. This situation is
-+ * detected, global cid_counter is incremented, and stored in highest bits of
-+ * all direntry offsets returned to the client, including last one. As the
-+ * only valid readdir cookie is one obtained as direntry->offset, we are
-+ * guaranteed that next readdir request (continuing current one) will have
-+ * current cid in the highest bits of starting readdir cookie. All d_cursors
-+ * are hashed into per-super-block hash table by (oid, cid) key.
-+ *
-+ * In addition d_cursors are placed into per-super-block radix tree where they
-+ * are keyed by oid alone. This is necessary to efficiently remove them during
-+ * rmdir.
-+ *
-+ * At last, currently unused d_cursors are linked into special list. This list
-+ * is used d_cursor_shrink to reclaim d_cursors on memory pressure.

-+ readdir problems:
-+
-+ readdir(2)/getdents(2) interface is based on implicit assumption that
-+ readdir can be restarted from any particular point by supplying file system
-+ with off_t-full of data. That is, file system fills ->d_off field in struct
-+ dirent and later user passes ->d_off to the seekdir(3), which is, actually,
-+ implemented by glibc as lseek(2) on directory.
-+
-+ Reiser4 cannot restart readdir from 64 bits of data, because two last
-+ components of the key of directory entry are unknown, which given 128 bits:
-+ locality and type fields in the key of directory entry are always known, to
-+ start readdir() from given point objectid and offset fields have to be
-+ filled.
-+
-+ Traditional UNIX API for scanning through directory
-+ (readdir/seekdir/telldir/opendir/closedir/rewindir/getdents) is based on the
-+ assumption that directory is structured very much like regular file, in
-+ particular, it is implied that each name within given directory (directory
-+ entry) can be uniquely identified by scalar offset and that such offset is
-+ stable across the life-time of the name is identifies.
-+
-+ This is manifestly not so for reiser4. In reiser4 the only stable unique
-+ identifies for the directory entry is its key that doesn't fit into
-+ seekdir/telldir API.
-+
-+ solution:
-+
-+ Within each file descriptor participating in readdir-ing of directory
-+ plugin/dir/dir.h:readdir_pos is maintained. This structure keeps track of
-+ the "current" directory entry that file descriptor looks at. It contains a
-+ key of directory entry (plus some additional info to deal with non-unique
-+ keys that we wouldn't dwell onto here) and a logical position of this
-+ directory entry starting from the beginning of the directory, that is
-+ ordinal number of this entry in the readdir order.
-+
-+ Obviously this logical position is not stable in the face of directory
-+ modifications. To work around this, on each addition or removal of directory
-+ entry all file descriptors for directory inode are scanned and their
-+ readdir_pos are updated accordingly (adjust_dir_pos()).

-+/* Directory entry implementation */
-+
-+/* DESCRIPTION:
-+
-+ This is "compound" directory item plugin implementation. This directory
-+ item type is compound (as opposed to the "simple directory item" in
-+ fs/reiser4/plugin/item/sde.[ch]), because it consists of several directory
-+ entries.
-+
-+ The reason behind this decision is disk space efficiency: all directory
-+ entries inside the same directory have identical fragment in their
-+ keys. This, of course, depends on key assignment policy. In our default key
-+ assignment policy, all directory entries have the same locality which is
-+ equal to the object id of their directory.
-+
-+ Composing directory item out of several directory entries for the same
-+ directory allows us to store said key fragment only once. That is, this is
-+ some ad hoc form of key compression (stem compression) that is implemented
-+ here, because general key compression is not supposed to be implemented in
-+ v4.0.
-+
-+ Another decision that was made regarding all directory item plugins, is
-+ that they will store entry keys unaligned. This is for that sake of disk
-+ space efficiency again.
-+
-+ In should be noted, that storing keys unaligned increases CPU consumption,
-+ at least on some architectures.
-+
-+ Internal on-disk structure of the compound directory item is the following:
-+
-+ HEADER cde_item_format. Here number of entries is stored.
-+ ENTRY_HEADER_0 cde_unit_header. Here part of entry key and
-+ ENTRY_HEADER_1 offset of entry body are stored.
-+ ENTRY_HEADER_2 (basically two last parts of key)
-+ ...
-+ ENTRY_HEADER_N
-+ ENTRY_BODY_0 directory_entry_format. Here part of stat data key and
-+ ENTRY_BODY_1 NUL-terminated name are stored.
-+ ENTRY_BODY_2 (part of statadta key in the
-+ sence that since all SDs have
-+ zero offset, this offset is not
-+ stored on disk).
-+ ...
-+ ENTRY_BODY_N
-+
-+ When it comes to the balancing, each directory entry in compound directory
-+ item is unit, that is, something that can be cut from one item and pasted
-+ into another item of the same type. Handling of unit cut and paste is major
-+ reason for the complexity of code below.

-+/* Stat data layout: goals and implementation.
-+
-+ We want to be able to have lightweight files which have complete flexibility in what semantic metadata is attached to
-+ them, including not having semantic metadata attached to them.
-+
-+ There is one problem with doing that, which is that if in fact you have exactly the same metadata for most files you
-+ want to store, then it takes more space to store that metadata in a dynamically sized structure than in a statically
-+ sized structure because the statically sized structure knows without recording it what the names and lengths of the
-+ attributes are.
-+
-+ This leads to a natural compromise, which is to special case those files which have simply the standard unix file
-+ attributes, and only employ the full dynamic stat data mechanism for those files that differ from the standard unix
-+ file in their use of file attributes.
-+
-+ Yet this compromise deserves to be compromised a little.
-+
-+ We accommodate the case where you have no more than the standard unix file attributes by using an "extension
-+ bitmask": each bit in it indicates presence or absence of or particular stat data extension (see sd_ext_bits enum).
-+
-+ If the first bit of the extension bitmask bit is 0, we have light-weight file whose attributes are either inherited
-+ from parent directory (as uid, gid) or initialised to some sane values.
-+
-+ To capitalize on existing code infrastructure, extensions are
-+ implemented as plugins of type REISER4_SD_EXT_PLUGIN_TYPE.
-+ Each stat-data extension plugin implements four methods:
-+
-+ ->present() called by sd_load() when this extension is found in stat-data
-+ ->absent() called by sd_load() when this extension is not found in stat-data
-+ ->save_len() called by sd_len() to calculate total length of stat-data
-+ ->save() called by sd_save() to store extension data into stat-data

-+/* Node plugin interface.
-+
-+ Description: The tree provides the abstraction of flows, which it
-+ internally fragments into items which it stores in nodes.
-+
-+ A key_atom is a piece of data bound to a single key.
-+
-+ For reasonable space efficiency to be achieved it is often
-+ necessary to store key_atoms in the nodes in the form of items, where
-+ an item is a sequence of key_atoms of the same or similar type. It is
-+ more space-efficient, because the item can implement (very)
-+ efficient compression of key_atom's bodies using internal knowledge
-+ about their semantics, and it can often avoid having a key for each
-+ key_atom. Each type of item has specific operations implemented by its
-+ item handler (see balance.c).
-+
-+ Rationale: the rest of the code (specifically balancing routines)
-+ accesses leaf level nodes through this interface. This way we can
-+ implement various block layouts and even combine various layouts
-+ within the same tree. Balancing/allocating algorithms should not
-+ care about peculiarities of splitting/merging specific item types,
-+ but rather should leave that to the item's item handler.
-+
-+ Items, including those that provide the abstraction of flows, have
-+ the property that if you move them in part or in whole to another
-+ node, the balancing code invokes their is_left_mergeable()
-+ item_operation to determine if they are mergeable with their new
-+ neighbor in the node you have moved them to. For some items the
-+ is_left_mergeable() function always returns null.
-+
-+ When moving the bodies of items from one node to another:
-+
-+ if a partial item is shifted to another node the balancing code invokes
-+ an item handler method to handle the item splitting.
-+
-+ if the balancing code needs to merge with an item in the node it
-+ is shifting to, it will invoke an item handler method to handle
-+ the item merging.
-+
-+ if it needs to move whole item bodies unchanged, the balancing code uses xmemcpy()
-+ adjusting the item headers after the move is done using the node handler.

-+/* We need a definition of the default node layout here. */
-+
-+/* Generally speaking, it is best to have free space in the middle of the
-+ node so that two sets of things can grow towards it, and to have the
-+ item bodies on the left so that the last one of them grows into free
-+ space. We optimize for the case where we append new items to the end
-+ of the node, or grow the last item, because it hurts nothing to so
-+ optimize and it is a common special case to do massive insertions in
-+ increasing key order (and one of cases more likely to have a real user
-+ notice the delay time for).
-+
-+ formatted leaf default layout: (leaf1)
-+
-+ |node header:item bodies:free space:key + pluginid + item offset|
-+
-+ We grow towards the middle, optimizing layout for the case where we
-+ append new items to the end of the node. The node header is fixed
-+ length. Keys, and item offsets plus pluginids for the items
-+ corresponding to them are in increasing key order, and are fixed
-+ length. Item offsets are relative to start of node (16 bits creating
-+ a node size limit of 64k, 12 bits might be a better choice....). Item
-+ bodies are in decreasing key order. Item bodies have a variable size.
-+ There is a one to one to one mapping of keys to item offsets to item
-+ bodies. Item offsets consist of pointers to the zeroth byte of the
-+ item body. Item length equals the start of the next item minus the
-+ start of this item, except the zeroth item whose length equals the end
-+ of the node minus the start of that item (plus a byte). In other
-+ words, the item length is not recorded anywhere, and it does not need
-+ to be since it is computable.
-+
-+ Leaf variable length items and keys layout : (lvar)
-+
-+ |node header:key offset + item offset + pluginid triplets:free space:key bodies:item bodies|
-+
-+ We grow towards the middle, optimizing layout for the case where we
-+ append new items to the end of the node. The node header is fixed
-+ length. Keys and item offsets for the items corresponding to them are
-+ in increasing key order, and keys are variable length. Item offsets
-+ are relative to start of node (16 bits). Item bodies are in
-+ decreasing key order. Item bodies have a variable size. There is a
-+ one to one to one mapping of keys to item offsets to item bodies.
-+ Item offsets consist of pointers to the zeroth byte of the item body.
-+ Item length equals the start of the next item's key minus the start of
-+ this item, except the zeroth item whose length equals the end of the
-+ node minus the start of that item (plus a byte).
-+
-+ leaf compressed keys layout: (lcomp)
-+
-+ |node header:key offset + key inherit + item offset pairs:free space:key bodies:item bodies|
-+
-+ We grow towards the middle, optimizing layout for the case where we
-+ append new items to the end of the node. The node header is fixed
-+ length. Keys and item offsets for the items corresponding to them are
-+ in increasing key order, and keys are variable length. The "key
-+ inherit" field indicates how much of the key prefix is identical to
-+ the previous key (stem compression as described in "Managing
-+ Gigabytes" is used). key_inherit is a one byte integer. The
-+ intra-node searches performed through this layout are linear searches,
-+ and this is theorized to not hurt performance much due to the high
-+ cost of processor stalls on modern CPUs, and the small number of keys
-+ in a single node. Item offsets are relative to start of node (16
-+ bits). Item bodies are in decreasing key order. Item bodies have a
-+ variable size. There is a one to one to one mapping of keys to item
-+ offsets to item bodies. Item offsets consist of pointers to the
-+ zeroth byte of the item body. Item length equals the start of the
-+ next item minus the start of this item, except the zeroth item whose
-+ length equals the end of the node minus the start of that item (plus a
-+ byte). In other words, item length and key length is not recorded
-+ anywhere, and it does not need to be since it is computable.
-+
-+ internal node default layout: (idef1)
-+
-+ just like ldef1 except that item bodies are either blocknrs of
-+ children or extents, and moving them may require updating parent
-+ pointers in the nodes that they point to.

-+ * Plugins associated with inode:
-+ *
-+ * Plugin of inode is plugin referenced by plugin-id field of on-disk
-+ * stat-data. How we store this plugin in in-core inode is not
-+ * important. Currently pointers are used, another variant is to store offsets
-+ * and do array lookup on each access.
-+ *
-+ * Now, each inode has one selected plugin: object plugin that
-+ * determines what type of file this object is: directory, regular etc.
-+ *
-+ * This main plugin can use other plugins that are thus subordinated to
-+ * it. Directory instance of object plugin uses hash; regular file
-+ * instance uses tail policy plugin.
-+ *
-+ * Object plugin is either taken from id in stat-data or guessed from
-+ * i_mode bits. Once it is established we ask it to install its
-+ * subordinate plugins, by looking again in stat-data or inheriting them
-+ * from parent.
-+ *
-+ * How new inode is initialized during ->read_inode():
-+ * 1 read stat-data and initialize inode fields: i_size, i_mode,
-+ * i_generation, capabilities etc.
-+ * 2 read plugin id from stat data or try to guess plugin id
-+ * from inode->i_mode bits if plugin id is missing.
-+ * 3 Call ->init_inode() method of stat-data plugin to initialise inode fields.
-+ *
-+ * NIKITA-FIXME-HANS: can you say a little about 1 being done before 3? What
-+ * if stat data does contain i_size, etc., due to it being an unusual plugin?
-+ *
-+ * 4 Call ->activate() method of object's plugin. Plugin is either read from
-+ * from stat-data or guessed from mode bits
-+ * 5 Call ->inherit() method of object plugin to inherit as yet un initialized
-+ * plugins from parent.
-+ *
-+ * Easy induction proves that on last step all plugins of inode would be
-+ * initialized.
-+ *
-+ * When creating new object:
-+ * 1 obtain object plugin id (see next period)
-+ * NIKITA-FIXME-HANS: period?
-+ * 2 ->install() this plugin
-+ * 3 ->inherit() the rest from the parent
-+ *
-+ * We need some examples of creating an object with default and non-default
-+ * plugin ids. Nikita, please create them.

-+/* Basic plugin infrastructure, lookup etc. */
-+
-+/* PLUGINS:
-+
-+ Plugins are internal Reiser4 "modules" or "objects" used to increase
-+ extensibility and allow external users to easily adapt reiser4 to
-+ their needs.
-+
-+ Plugins are classified into several disjoint "types". Plugins
-+ belonging to the particular plugin type are termed "instances" of
-+ this type. Currently the following types are present:
-+
-+ . object plugin
-+ . hash plugin
-+ . tail plugin
-+ . perm plugin
-+ . item plugin
-+ . node layout plugin
-+
-+NIKITA-FIXME-HANS: update this list, and review this entire comment for currency
-+
-+ Object (file) plugin determines how given file-system object serves
-+ standard VFS requests for read, write, seek, mmap etc. Instances of
-+ file plugins are: regular file, directory, symlink. Another example
-+ of file plugin is audit plugin, that optionally records accesses to
-+ underlying object and forwards requests to it.
-+
-+ Hash plugins compute hashes used by reiser4 to store and locate
-+ files within directories. Instances of hash plugin type are: r5,
-+ tea, rupasov.
-+
-+ Tail plugins (or, more precisely, tail policy plugins) determine
-+ when last part of the file should be stored in a formatted item.
-+
-+ Perm plugins control permissions granted for a process accessing a file.
-+
-+ Scope and lookup:
-+
-+ label such that pair ( type_label, plugin_label ) is unique. This
-+ pair is a globally persistent and user-visible plugin
-+ identifier. Internally kernel maintains plugins and plugin types in
-+ arrays using an index into those arrays as plugin and plugin type
-+ identifiers. File-system in turn, also maintains persistent
-+ "dictionary" which is mapping from plugin label to numerical
-+ identifier which is stored in file-system objects. That is, we
-+ store the offset into the plugin array for that plugin type as the
-+ plugin id in the stat data of the filesystem object.
-+
-+ plugin_labels have meaning for the user interface that assigns
-+ plugins to files, and may someday have meaning for dynamic loading of
-+ plugins and for copying of plugins from one fs instance to
-+ another by utilities like cp and tar.
-+
-+ Internal kernel plugin type identifier (index in plugins[] array) is
-+ of type reiser4_plugin_type. Set of available plugin types is
-+ currently static, but dynamic loading doesn't seem to pose
-+ insurmountable problems.
-+
-+ Within each type plugins are addressed by the identifiers of type
-+ reiser4_plugin_id (indices in
-+ reiser4_plugin_type_data.builtin[]). Such identifiers are only
-+ required to be unique within one type, not globally.
-+
-+ Thus, plugin in memory is uniquely identified by the pair (type_id,
-+ id).
-+
-+ Usage:
-+
-+ There exists only one instance of each plugin instance, but this
-+ single instance can be associated with many entities (file-system
-+ objects, items, nodes, transactions, file-descriptors etc.). Entity
-+ to which plugin of given type is termed (due to the lack of
-+ imagination) "subject" of this plugin type and, by abuse of
-+ terminology, subject of particular instance of this type to which
-+ it's attached currently. For example, inode is subject of object
-+ plugin type. Inode representing directory is subject of directory
-+ plugin, hash plugin type and some particular instance of hash plugin
-+ type. Inode, representing regular file is subject of "regular file"
-+ plugin, tail-policy plugin type etc.
-+
-+ With each subject the plugin possibly stores some state. For example,
-+ the state of a directory plugin (instance of object plugin type) is pointer
-+ to hash plugin (if directories always use hashing that is). State of
-+ audit plugin is file descriptor (struct file) of log file or some
-+ magic value to do logging through printk().
-+
-+ Interface:
-+
-+ In addition to a scalar identifier, each plugin type and plugin
-+ proper has a "label": short string and a "description"---longer
-+ descriptive string. Labels and descriptions of plugin types are
-+ hard-coded into plugins[] array, declared and defined in
-+ plugin.c. Label and description of plugin are stored in .label and
-+ .desc fields of reiser4_plugin_header respectively. It's possible to
-+ locate plugin by the pair of labels.
-+
-+ Features:
-+
-+ . user-level plugin manipulations:
-+ + reiser4("filename/..file_plugin<='audit'");
-+ + write(open("filename/..file_plugin"), "audit", 8);
-+
-+ . user level utilities lsplug and chplug to manipulate plugins.
-+ Utilities are not of primary priority. Possibly they will be not
-+ working on v4.0
-+
-+NIKITA-FIXME-HANS: this should be a mkreiserfs option not a mount option, do you agree? I don't think that specifying it at mount time, and then changing it with each mount, is a good model for usage.
-+
-+ . mount option "plug" to set-up plugins of root-directory.
-+ "plug=foo:bar" will set "bar" as default plugin of type "foo".
-+
-+ Limitations:
-+
-+ . each plugin type has to provide at least one builtin
-+ plugin. This is technical limitation and it can be lifted in the
-+ future.
-+
-+ TODO:
-+
-+ New plugin types/plugings:
-+ Things we should be able to separately choose to inherit:
-+
-+ security plugins
-+
-+ stat data
-+
-+ file bodies
-+
-+ file plugins
-+
-+ dir plugins
-+
-+ . perm:acl
-+
-+ d audi---audit plugin intercepting and possibly logging all
-+ accesses to object. Requires to put stub functions in file_operations
-+ in stead of generic_file_*.
-+
-+NIKITA-FIXME-HANS: why make overflows a plugin?
-+ . over---handle hash overflows
-+
-+ . sqnt---handle different access patterns and instruments read-ahead
-+
-+NIKITA-FIXME-HANS: describe the line below in more detail.
-+
-+ . hier---handle inheritance of plugins along file-system hierarchy
-+
-+ Different kinds of inheritance: on creation vs. on access.
-+ Compatible/incompatible plugins.
-+ Inheritance for multi-linked files.
-+ Layered plugins.
-+ Notion of plugin context is abandoned.
-+
-+Each file is associated
-+ with one plugin and dependant plugins (hash, etc.) are stored as
-+ main plugin state. Now, if we have plugins used for regular files
-+ but not for directories, how such plugins would be inherited?
-+ . always store them with directories also
-+
-+NIKTIA-FIXME-HANS: Do the line above. It is not exclusive of doing the line below which is also useful.
-+
-+ . use inheritance hierarchy, independent of file-system namespace

-+ * File plugin. Defines the set of methods that file plugins implement, some
-+ * of which are optional.
-+ *
-+ * A file plugin offers to the caller an interface for IO ( writing to and/or
-+ * reading from) to what the caller sees as one sequence of bytes. An IO to it
-+ * may affect more than one physical sequence of bytes, or no physical sequence
-+ * of bytes, it may affect sequences of bytes offered by other file plugins to
-+ * the semantic layer, and the file plugin may invoke other plugins and
-+ * delegate work to them, but its interface is structured for offering the
-+ * caller the ability to read and/or write what the caller sees as being a
-+ * single sequence of bytes.
-+ *
-+ * The file plugin must present a sequence of bytes to the caller, but it does
-+ * not necessarily have to store a sequence of bytes, it does not necessarily
-+ * have to support efficient tree traversal to any offset in the sequence of
-+ * bytes (tail and extent items, whose keys contain offsets, do however provide
-+ * efficient non-sequential lookup of any offset in the sequence of bytes).
-+ *
-+ * Directory plugins provide methods for selecting file plugins by resolving a
-+ * name for them.
-+ *
-+ * The functionality other filesystems call an attribute, and rigidly tie
-+ * together, we decompose into orthogonal selectable features of files. Using
-+ * the terminology we will define next, an attribute is a perhaps constrained,
-+ * perhaps static length, file whose parent has a uni-count-intra-link to it,
-+ * which might be grandparent-major-packed, and whose parent has a deletion
-+ * method that deletes it.
-+ *
-+ * File plugins can implement constraints.
-+ *
-+ * Files can be of variable length (e.g. regular unix files), or of static
-+ * length (e.g. static sized attributes).
-+ *
-+ * An object may have many sequences of bytes, and many file plugins, but, it
-+ * has exactly one objectid. It is usually desirable that an object has a
-+ * deletion method which deletes every item with that objectid. Items cannot
-+ * in general be found by just their objectids. This means that an object must
-+ * have either a method built into its deletion plugin method for knowing what
-+ * items need to be deleted, or links stored with the object that provide the
-+ * plugin with a method for finding those items. Deleting a file within an
-+ * object may or may not have the effect of deleting the entire object,
-+ * depending on the file plugin's deletion method.
-+ *
-+ * LINK TAXONOMY:
-+ *
-+ * Many objects have a reference count, and when the reference count reaches 0
-+ * the object's deletion method is invoked. Some links embody a reference
-+ * count increase ("countlinks"), and others do not ("nocountlinks").
-+ *
-+ * Some links are bi-directional links ("bilinks"), and some are
-+ * uni-directional("unilinks").
-+ *
-+ * Some links are between parts of the same object ("intralinks"), and some are
-+ * between different objects ("interlinks").
-+ *
-+ * PACKING TAXONOMY:
-+ *
-+ * Some items of an object are stored with a major packing locality based on
-+ * their object's objectid (e.g. unix directory items in plan A), and these are
-+ * called "self-major-packed".
-+ *
-+ * Some items of an object are stored with a major packing locality based on
-+ * their semantic parent object's objectid (e.g. unix file bodies in plan A),
-+ * and these are called "parent-major-packed".
-+ *
-+ * Some items of an object are stored with a major packing locality based on
-+ * their semantic grandparent, and these are called "grandparent-major-packed".
-+ * Now carefully notice that we run into trouble with key length if we have to
-+ * store a 8 byte major+minor grandparent based packing locality, an 8 byte
-+ * parent objectid, an 8 byte attribute objectid, and an 8 byte offset, all in
-+ * a 24 byte key. One of these fields must be sacrificed if an item is to be
-+ * grandparent-major-packed, and which to sacrifice is left to the item author
-+ * choosing to make the item grandparent-major-packed. You cannot make tail
-+ * items and extent items grandparent-major-packed, though you could make them
-+ * self-major-packed (usually they are parent-major-packed).
-+ *
-+ * In the case of ACLs (which are composed of fixed length ACEs which consist
-+ * of {subject-type, subject, and permission bitmask} triples), it makes sense
-+ * to not have an offset field in the ACE item key, and to allow duplicate keys
-+ * for ACEs. Thus, the set of ACES for a given file is found by looking for a
-+ * key consisting of the objectid of the grandparent (thus grouping all ACLs in
-+ * a directory together), the minor packing locality of ACE, the objectid of
-+ * the file, and 0.
-+ *
-+ * IO involves moving data from one location to another, which means that two
-+ * locations must be specified, source and destination.
-+ *
-+ * This source and destination can be in the filesystem, or they can be a
-+ * pointer in the user process address space plus a byte count.
-+ *
-+ * If both source and destination are in the filesystem, then at least one of
-+ * them must be representable as a pure stream of bytes (which we call a flow,
-+ * and define as a struct containing a key, a data pointer, and a length).
-+ * This may mean converting one of them into a flow. We provide a generic
-+ * cast_into_flow() method, which will work for any plugin supporting
-+ * read_flow(), though it is inefficiently implemented in that it temporarily
-+ * stores the flow in a buffer (Question: what to do with huge flows that
-+ * cannot fit into memory? Answer: we must not convert them all at once. )
-+ *
-+ * Performing a write requires resolving the write request into a flow defining
-+ * the source, and a method that performs the write, and a key that defines
-+ * where in the tree the write is to go.
-+ *
-+ * Performing a read requires resolving the read request into a flow defining
-+ * the target, and a method that performs the read, and a key that defines
-+ * where in the tree the read is to come from.
-+ *
-+ * There will exist file plugins which have no pluginid stored on the disk for
-+ * them, and which are only invoked by other plugins.

-+/* Proposed (but discarded) optimization: dynamic loading/unloading of bitmap
-+ * blocks
-+
-+ A useful optimization of reiser4 bitmap handling would be dynamic bitmap
-+ blocks loading/unloading which is different from v3.x where all bitmap
-+ blocks are loaded at mount time.
-+
-+ To implement bitmap blocks unloading we need to count bitmap block usage
-+ and detect currently unused blocks allowing them to be unloaded. It is not
-+ a simple task since we allow several threads to modify one bitmap block
-+ simultaneously.
-+
-+ Briefly speaking, the following schema is proposed: we count in special
-+ variable associated with each bitmap block. That is for counting of block
-+ alloc/dealloc operations on that bitmap block. With a deferred block
-+ deallocation feature of reiser4 all those operation will be represented in
-+ atom dirty/deleted lists as jnodes for freshly allocated or deleted
-+ nodes.
-+
-+ So, we increment usage counter for each new node allocated or deleted, and
-+ decrement it at atom commit one time for each node from the dirty/deleted
-+ atom's list. Of course, freshly allocated node deletion and node reusing
-+ from atom deleted (if we do so) list should decrement bitmap usage counter
-+ also.
-+
-+ This schema seems to be working but that reference counting is
-+ not easy to debug. I think we should agree with Hans and do not implement
-+ it in v4.0. Current code implements "on-demand" bitmap blocks loading only.
-+
-+ For simplicity all bitmap nodes (both commit and working bitmap blocks) are
-+ loaded into memory on fs mount time or each bitmap nodes are loaded at the
-+ first access to it, the "dont_load_bitmap" mount option controls whether
-+ bimtap nodes should be loaded at mount time. Dynamic unloading of bitmap
-+ nodes currently is not supported. */

-+/* Fast pool allocation.
-+
-+ There are situations when some sub-system normally asks memory allocator
-+ for only few objects, but under some circumstances could require much
-+ more. Typical and actually motivating example is tree balancing. It needs
-+ to keep track of nodes that were involved into it, and it is well-known
-+ that in reasonable packed balanced tree most (92.938121%) percent of all
-+ balancings end up after working with only few nodes (3.141592 on
-+ average). But in rare cases balancing can involve much more nodes
-+ (3*tree_height+1 in extremal situation).
-+
-+ On the one hand, we don't want to resort to dynamic allocation (slab,
-+ malloc(), etc.) to allocate data structures required to keep track of
-+ nodes during balancing. On the other hand, we cannot statically allocate
-+ required amount of space on the stack, because first: it is useless wastage
-+ of precious resource, and second: this amount is unknown in advance (tree
-+ height can change).
-+
-+ Pools, implemented in this file are solution for this problem:
-+
-+ - some configurable amount of objects is statically preallocated on the
-+ stack
-+
-+ - if this preallocated pool is exhausted and more objects is requested
-+ they are allocated dynamically.
-+
-+ Pools encapsulate distinction between statically and dynamically allocated
-+ objects. Both allocation and recycling look exactly the same.
-+
-+ To keep track of dynamically allocated objects, pool adds its own linkage
-+ to each object.
-+
-+ NOTE-NIKITA This linkage also contains some balancing-specific data. This
-+ is not perfect. On the other hand, balancing is currently the only client
-+ of pool code.
-+
-+ NOTE-NIKITA Another desirable feature is to rewrite all pool manipulation
-+ functions in the style of tslist/tshash, i.e., make them unreadable, but
-+ type-safe.

-+/*
-+ * Safe-links are used to maintain file system consistency during operations
-+ * that spawns multiple transactions. For example:
-+ *
-+ * 1. Unlink. UNIX supports "open-but-unlinked" files, that is files
-+ * without user-visible names in the file system, but still opened by some
-+ * active process. What happens here is that unlink proper (i.e., removal
-+ * of the last file name) and file deletion (truncate of file body to zero
-+ * and deletion of stat-data, that happens when last file descriptor is
-+ * closed), may belong to different transactions T1 and T2. If a crash
-+ * happens after T1 commit, but before T2 commit, on-disk file system has
-+ * a file without name, that is, disk space leak.
-+ *
-+ * 2. Truncate. Truncate of large file may spawn multiple transactions. If
-+ * system crashes while truncate was in-progress, file is left partially
-+ * truncated, which violates "atomicity guarantees" of reiser4, viz. that
-+ * every system is atomic.
-+ *
-+ * Safe-links address both above cases. Basically, safe-link is a way post
-+ * some operation to be executed during commit of some other transaction than
-+ * current one. (Another way to look at the safe-link is to interpret it as a
-+ * logical logging.)
-+ *
-+ * Specifically, at the beginning of unlink safe-link in inserted in the
-+ * tree. This safe-link is normally removed by file deletion code (during
-+ * transaction T2 in the above terms). Truncate also inserts safe-link that is
-+ * normally removed when truncate operation is finished.
-+ *
-+ * This means, that in the case of "clean umount" there are no safe-links in
-+ * the tree. If safe-links are observed during mount, it means that (a) system
-+ * was terminated abnormally, and (b) safe-link correspond to the "pending"
-+ * (i.e., not finished) operations that were in-progress during system
-+ * termination. Each safe-link record enough information to complete
-+ * corresponding operation, and mount simply "replays" them (hence, the
-+ * analogy with the logical logging).
-+ *
-+ * Safe-links are implemented as blackbox items (see
-+ * plugin/item/blackbox.[ch]).
-+ *
-+ * For the reference: ext3 also has similar mechanism, it's called "an orphan
-+ * list" there.

-+/* Seals implementation. */
-+/* Seals are "weak" tree pointers. They are analogous to tree coords in
-+ allowing to bypass tree traversal. But normal usage of coords implies that
-+ node pointed to by coord is locked, whereas seals don't keep a lock (or
-+ even a reference) to znode. In stead, each znode contains a version number,
-+ increased on each znode modification. This version number is copied into a
-+ seal when seal is created. Later, one can "validate" seal by calling
-+ seal_validate(). If znode is in cache and its version number is still the
-+ same, seal is "pristine" and coord associated with it can be re-used
-+ immediately.
-+
-+ If, on the other hand, znode is out of cache, or it is obviously different
-+ one from the znode seal was initially attached to (for example, it is on
-+ the different level, or is being removed from the tree), seal is
-+ irreparably invalid ("burned") and tree traversal has to be repeated.
-+
-+ Otherwise, there is some hope, that while znode was modified (and seal was
-+ "broken" as a result), key attached to the seal is still in the node. This
-+ is checked by first comparing this key with delimiting keys of node and, if
-+ key is ok, doing intra-node lookup.
-+
-+ Znode version is maintained in the following way:
-+
-+ there is reiser4_tree.znode_epoch counter. Whenever new znode is created,
-+ znode_epoch is incremented and its new value is stored in ->version field
-+ of new znode. Whenever znode is dirtied (which means it was probably
-+ modified), znode_epoch is also incremented and its new value is stored in
-+ znode->version. This is done so, because just incrementing znode->version
-+ on each update is not enough: it may so happen, that znode get deleted, new
-+ znode is allocated for the same disk block and gets the same version
-+ counter, tricking seal code into false positive.

-+ * from the tree root) node such that all body items of said object are
-+ * located in a tree rooted at this node.
-+ *
-+ * Once vroot of object is found all tree lookups for items within body of
-+ * this object ("object lookups") can be started from its vroot rather
-+ * than from real root. This has following advantages:
-+ *
-+ * 1. amount of nodes traversed during lookup (and, hence, amount of
-+ * key comparisons made) decreases, and
-+ *
-+ * 2. contention on tree root is decreased. This latter was actually
-+ * motivating reason behind vroot, because spin lock of root node,
-+ * which is taken when acquiring long-term lock on root node is the
-+ * hottest lock in the reiser4.
-+ *
-+ * How to find vroot.
-+ *
-+ * When vroot of object F is not yet determined, all object lookups start
-+ * from the root of the tree. At each tree level during traversal we have
-+ * a node N such that a key we are looking for (which is the key inside
-+ * object's body) is located within N. In function handle_vroot() called
-+ * from cbk_level_lookup() we check whether N is possible vroot for
-+ * F. Check is trivial---if neither leftmost nor rightmost item of N
-+ * belongs to F (and we already have helpful ->owns_item() method of
-+ * object plugin for this), then N is possible vroot of F. This, of
-+ * course, relies on the assumption that each object occupies contiguous
-+ * range of keys in the tree.
-+ *
-+ * Thus, traversing tree downward and checking each node as we go, we can
-+ * find lowest such node, which, by definition, is vroot.
-+ *
-+ * How to track vroot.
-+ *
-+ * Nohow. If actual vroot changes, next object lookup will just restart
-+ * from the actual tree root, refreshing object's vroot along the way.

-+/*
-+ * KEYS IN A TREE.
-+ *
-+ * The tree consists of nodes located on the disk. Node in the tree is either
-+ * formatted or unformatted. Formatted node is one that has structure
-+ * understood by the tree balancing and traversal code. Formatted nodes are
-+ * further classified into leaf and internal nodes. Latter distinctions is
-+ * (almost) of only historical importance: general structure of leaves and
-+ * internal nodes is the same in Reiser4. Unformatted nodes contain raw data
-+ * that are part of bodies of ordinary files and attributes.
-+ *
-+ * Each node in the tree spawns some interval in the key space. Key ranges for
-+ * all nodes in the tree are disjoint. Actually, this only holds in some weak
-+ * sense, because of the non-unique keys: intersection of key ranges for
-+ * different nodes is either empty, or consists of exactly one key.
-+ *
-+ * Formatted node consists of a sequence of items. Each item spawns some
-+ * interval in key space. Key ranges for all items in a tree are disjoint,
-+ * modulo non-unique keys again. Items within nodes are ordered in the key
-+ * order of the smallest key in a item.
-+ *
-+ * Particular type of item can be further split into units. Unit is piece of
-+ * item that can be cut from item and moved into another item of the same
-+ * time. Units are used by balancing code to repack data during balancing.
-+ *
-+ * Unit can be further split into smaller entities (for example, extent unit
-+ * represents several pages, and it is natural for extent code to operate on
-+ * particular pages and even bytes within one unit), but this is of no
-+ * relevance to the generic balancing and lookup code.
-+ *
-+ * Although item is said to "spawn" range or interval of keys, it is not
-+ * necessary that item contains piece of data addressable by each and every
-+ * key in this range. For example, compound directory item, consisting of
-+ * units corresponding to directory entries and keyed by hashes of file names,
-+ * looks more as having "discrete spectrum": only some disjoint keys inside
-+ * range occupied by this item really address data.
-+ *
-+ * No than less, each item always has well-defined least (minimal) key, that
-+ * is recorded in item header, stored in the node this item is in. Also, item
-+ * plugin can optionally define method ->max_key_inside() returning maximal
-+ * key that can _possibly_ be located within this item. This method is used
-+ * (mainly) to determine when given piece of data should be merged into
-+ * existing item, in stead of creating new one. Because of this, even though
-+ * ->max_key_inside() can be larger that any key actually located in the item,
-+ * intervals
-+ *
-+ * [ min_key( item ), ->max_key_inside( item ) ]
-+ *
-+ * are still disjoint for all items within the _same_ node.
-+ *
-+ * In memory node is represented by znode. It plays several roles:
-+ *
-+ * . something locks are taken on
-+ *
-+ * . something tracked by transaction manager (this is going to change)
-+ *
-+ * . something used to access node data
-+ *
-+ * . something used to maintain tree structure in memory: sibling and
-+ * parental linkage.
-+ *
-+ * . something used to organize nodes into "slums"
-+ *
-+ * More on znodes see in znode.[ch]
-+ *
-+ * DELIMITING KEYS
-+ *
-+ * To simplify balancing, allow some flexibility in locking and speed up
-+ * important coord cache optimization, we keep delimiting keys of nodes in
-+ * memory. Depending on disk format (implemented by appropriate node plugin)
-+ * node on disk can record both left and right delimiting key, only one of
-+ * them, or none. Still, our balancing and tree traversal code keep both
-+ * delimiting keys for a node that is in memory stored in the znode. When
-+ * node is first brought into memory during tree traversal, its left
-+ * delimiting key is taken from its parent, and its right delimiting key is
-+ * either next key in its parent, or is right delimiting key of parent if
-+ * node is the rightmost child of parent.
-+ *
-+ * Physical consistency of delimiting key is protected by special dk
-+ * read-write lock. That is, delimiting keys can only be inspected or
-+ * modified under this lock. But dk lock is only sufficient for fast
-+ * "pessimistic" check, because to simplify code and to decrease lock
-+ * contention, balancing (carry) only updates delimiting keys right before
-+ * unlocking all locked nodes on the given tree level. For example,
-+ * coord-by-key cache scans LRU list of recently accessed znodes. For each
-+ * node it first does fast check under dk spin lock. If key looked for is
-+ * not between delimiting keys for this node, next node is inspected and so
-+ * on. If key is inside of the key range, long term lock is taken on node
-+ * and key range is rechecked.
-+ *
-+ * COORDINATES
-+ *
-+ * To find something in the tree, you supply a key, and the key is resolved
-+ * by coord_by_key() into a coord (coordinate) that is valid as long as the
-+ * node the coord points to remains locked. As mentioned above trees
-+ * consist of nodes that consist of items that consist of units. A unit is
-+ * the smallest and indivisible piece of tree as far as balancing and tree
-+ * search are concerned. Each node, item, and unit can be addressed by
-+ * giving its level in the tree and the key occupied by this entity. A node
-+ * knows what the key ranges are of the items within it, and how to find its
-+ * items and invoke their item handlers, but it does not know how to access
-+ * individual units within its items except through the item handlers.
-+ * coord is a structure containing a pointer to the node, the ordinal number
-+ * of the item within this node (a sort of item offset), and the ordinal
-+ * number of the unit within this item.
-+ *
-+ * TREE LOOKUP
-+ *
-+ * There are two types of access to the tree: lookup and modification.
-+ *
-+ * Lookup is a search for the key in the tree. Search can look for either
-+ * exactly the key given to it, or for the largest key that is not greater
-+ * than the key given to it. This distinction is determined by "bias"
-+ * parameter of search routine (coord_by_key()). coord_by_key() either
-+ * returns error (key is not in the tree, or some kind of external error
-+ * occurred), or successfully resolves key into coord.
-+ *
-+ * This resolution is done by traversing tree top-to-bottom from root level
-+ * to the desired level. On levels above twig level (level one above the
-+ * leaf level) nodes consist exclusively of internal items. Internal item is
-+ * nothing more than pointer to the tree node on the child level. On twig
-+ * level nodes consist of internal items intermixed with extent
-+ * items. Internal items form normal search tree structure used by traversal
-+ * to descent through the tree.
-+ *
-+ * TREE LOOKUP OPTIMIZATIONS
-+ *
-+ * Tree lookup described above is expensive even if all nodes traversed are
-+ * already in the memory: for each node binary search within it has to be
-+ * performed and binary searches are CPU consuming and tend to destroy CPU
-+ * caches.
-+ *
-+ * Several optimizations are used to work around this:
-+ *
-+ * . cbk_cache (look-aside cache for tree traversals, see search.c for
-+ * details)
-+ *
-+ * . seals (see seal.[ch])
-+ *
-+ * . vroot (see search.c)
-+ *
-+ * General search-by-key is layered thusly:
-+ *
-+ * [check seal, if any] --ok--> done
-+ * |
-+ * failed
-+ * |
-+ * V
-+ * [vroot defined] --no--> node = tree_root
-+ * | |
-+ * yes |
-+ * | |
-+ * V |
-+ * node = vroot |
-+ * | |
-+ * | |
-+ * | |
-+ * V V
-+ * [check cbk_cache for key] --ok--> done
-+ * |
-+ * failed
-+ * |
-+ * V
-+ * [start tree traversal from node]

-+ current node, only then we really pack node (local ra only).

-+/* Thoughts on the external transaction interface:
-+
-+ In the current code, a TRANSCRASH handle is created implicitly by init_context() (which
-+ creates state that lasts for the duration of a system call and is called at the start
-+ of ReiserFS methods implementing VFS operations), and closed by reiser4_exit_context(),
-+ occupying the scope of a single system call. We wish to give certain applications an
-+ interface to begin and close (commit) transactions. Since our implementation of
-+ transactions does not yet support isolation, allowing an application to open a
-+ transaction implies trusting it to later close the transaction. Part of the
-+ transaction interface will be aimed at enabling that trust, but the interface for
-+ actually using transactions is fairly narrow.
-+
-+ BEGIN_TRANSCRASH: Returns a transcrash identifier. It should be possible to translate
-+ this identifier into a string that a shell-script could use, allowing you to start a
-+ transaction by issuing a command. Once open, the transcrash should be set in the task
-+ structure, and there should be options (I suppose) to allow it to be carried across
-+ fork/exec. A transcrash has several options:
-+
-+ - READ_FUSING or WRITE_FUSING: The default policy is for txn-capture to capture only
-+ on writes (WRITE_FUSING) and allow "dirty reads". If the application wishes to
-+ capture on reads as well, it should set READ_FUSING.
-+
-+ - TIMEOUT: Since a non-isolated transcrash cannot be undone, every transcrash must
-+ eventually close (or else the machine must crash). If the application dies an
-+ unexpected death with an open transcrash, for example, or if it hangs for a long
-+ duration, one solution (to avoid crashing the machine) is to simply close it anyway.
-+ This is a dangerous option, but it is one way to solve the problem until isolated
-+ transcrashes are available for untrusted applications.
-+
-+ It seems to be what databases do, though it is unclear how one avoids a DoS attack
-+ creating a vulnerability based on resource starvation. Guaranteeing that some
-+ minimum amount of computational resources are made available would seem more correct
-+ than guaranteeing some amount of time. When we again have someone to code the work,
-+ this issue should be considered carefully. -Hans
-+
-+ RESERVE_BLOCKS: A running transcrash should indicate to the transaction manager how
-+ many dirty blocks it expects. The reserve_blocks interface should be called at a point
-+ where it is safe for the application to fail, because the system may not be able to
-+ grant the allocation and the application must be able to back-out. For this reason,
-+ the number of reserve-blocks can also be passed as an argument to BEGIN_TRANSCRASH, but
-+ the application may also wish to extend the allocation after beginning its transcrash.
-+
-+ CLOSE_TRANSCRASH: The application closes the transcrash when it is finished making
-+ modifications that require transaction protection. When isolated transactions are
-+ supported the CLOSE operation is replaced by either COMMIT or ABORT. For example, if a
-+ RESERVE_BLOCKS call fails for the application, it should "abort" by calling
-+ CLOSE_TRANSCRASH, even though it really commits any changes that were made (which is
-+ why, for safety, the application should call RESERVE_BLOCKS before making any changes).
-+
-+ For actually implementing these out-of-system-call-scopped transcrashes, the
-+ reiser4_context has a "txn_handle *trans" pointer that may be set to an open
-+ transcrash. Currently there are no dynamically-allocated transcrashes, but there is a
-+ "kmem_cache_t *_txnh_slab" created for that purpose in this file.
-+*/
-+
-+/* Extending the other system call interfaces for future transaction features:
-+
-+ Specialized applications may benefit from passing flags to the ordinary system call
-+ interface such as read(), write(), or stat(). For example, the application specifies
-+ WRITE_FUSING by default but wishes to add that a certain read() command should be
-+ treated as READ_FUSING. But which read? Is it the directory-entry read, the stat-data
-+ read, or the file-data read? These issues are straight-forward, but there are a lot of
-+ them and adding the necessary flags-passing code will be tedious.
-+
-+ When supporting isolated transactions, there is a corresponding READ_MODIFY_WRITE (RMW)
-+ flag, which specifies that although it is a read operation being requested, a
-+ write-lock should be taken. The reason is that read-locks are shared while write-locks
-+ are exclusive, so taking a read-lock when a later-write is known in advance will often
-+ leads to deadlock. If a reader knows it will write later, it should issue read
-+ requests with the RMW flag set.
-+*/
-+
-+/*
-+ The znode/atom deadlock avoidance.
-+
-+ FIXME(Zam): writing of this comment is in progress.
-+
-+ The atom's special stage ASTAGE_CAPTURE_WAIT introduces a kind of atom's
-+ long-term locking, which makes reiser4 locking scheme more complex. It had
-+ deadlocks until we implement deadlock avoidance algorithms. That deadlocks
-+ looked as the following: one stopped thread waits for a long-term lock on
-+ znode, the thread who owns that lock waits when fusion with another atom will
-+ be allowed.
-+
-+ The source of the deadlocks is an optimization of not capturing index nodes
-+ for read. Let's prove it. Suppose we have dumb node capturing scheme which
-+ unconditionally captures each block before locking it.
-+
-+ That scheme has no deadlocks. Let's begin with the thread which stage is
-+ ASTAGE_CAPTURE_WAIT and it waits for a znode lock. The thread can't wait for
-+ a capture because it's stage allows fusion with any atom except which are
-+ being committed currently. A process of atom commit can't deadlock because
-+ atom commit procedure does not acquire locks and does not fuse with other
-+ atoms. Reiser4 does capturing right before going to sleep inside the
-+ longtertm_lock_znode() function, it means the znode which we want to lock is
-+ already captured and its atom is in ASTAGE_CAPTURE_WAIT stage. If we
-+ continue the analysis we understand that no one process in the sequence may
-+ waits atom fusion. Thereby there are no deadlocks of described kind.
-+
-+ The capturing optimization makes the deadlocks possible. A thread can wait a
-+ lock which owner did not captured that node. The lock owner's current atom
-+ is not fused with the first atom and it does not get a ASTAGE_CAPTURE_WAIT
-+ state. A deadlock is possible when that atom meets another one which is in
-+ ASTAGE_CAPTURE_WAIT already.
-+
-+ The deadlock avoidance scheme includes two algorithms:
-+
-+ First algorithm is used when a thread captures a node which is locked but not
-+ captured by another thread. Those nodes are marked MISSED_IN_CAPTURE at the
-+ moment we skip their capturing. If such a node (marked MISSED_IN_CAPTURE) is
-+ being captured by a thread with current atom is in ASTAGE_CAPTURE_WAIT, the
-+ routine which forces all lock owners to join with current atom is executed.
-+
-+ Second algorithm does not allow to skip capturing of already captured nodes.
-+
-+ Both algorithms together prevent waiting a longterm lock without atom fusion
-+ with atoms of all lock owners, which is a key thing for getting atom/znode
-+ locking deadlocks.

-+ * Transactions and mmap(2).
-+ *
-+ * 1. Transactions are not supported for accesses through mmap(2), because
-+ * this would effectively amount to user-level transactions whose duration
-+ * is beyond control of the kernel.
-+ *
-+ * 2. That said, we still want to preserve some decency with regard to
-+ * mmap(2). During normal write(2) call, following sequence of events
-+ * happens:
-+ *
-+ * 1. page is created;
-+ *
-+ * 2. jnode is created, dirtied and captured into current atom.
-+ *
-+ * 3. extent is inserted and modified.
-+ *
-+ * Steps (2) and (3) take place under long term lock on the twig node.
-+ *
-+ * When file is accessed through mmap(2) page is always created during
-+ * page fault. After this (in reiser4_readpage()->readpage_extent()):
-+ *
-+ * 1. if access is made to non-hole page new jnode is created, (if
-+ * necessary)
-+ *
-+ * 2. if access is made to the hole page, jnode is not created (XXX
-+ * not clear why).
-+ *
-+ * Also, even if page is created by write page fault it is not marked
-+ * dirty immediately by handle_mm_fault(). Probably this is to avoid races
-+ * with page write-out.
-+ *
-+ * Dirty bit installed by hardware is only transferred to the struct page
-+ * later, when page is unmapped (in zap_pte_range(), or
-+ * try_to_unmap_one()).
-+ *
-+ * So, with mmap(2) we have to handle following irksome situations:
-+ *
-+ * 1. there exists modified page (clean or dirty) without jnode
-+ *
-+ * 2. there exists modified page (clean or dirty) with clean jnode
-+ *
-+ * 3. clean page which is a part of atom can be transparently modified
-+ * at any moment through mapping without becoming dirty.
-+ *
-+ * (1) and (2) can lead to the out-of-memory situation: ->writepage()
-+ * doesn't know what to do with such pages and ->sync_sb()/->writepages()
-+ * don't see them, because these methods operate on atoms.
-+ *
-+ * (3) can lead to the loss of data: suppose we have dirty page with dirty
-+ * captured jnode captured by some atom. As part of early flush (for
-+ * example) page was written out. Dirty bit was cleared on both page and
-+ * jnode. After this page is modified through mapping, but kernel doesn't
-+ * notice and just discards page and jnode as part of commit. (XXX
-+ * actually it doesn't, because to reclaim page ->releasepage() has to be
-+ * called and before this dirty bit will be transferred to the struct
-+ * page).

-+
-+ This routine encodes the basic logic of block capturing described by:
-+
-+ http://namesys.com/v4/v4.html
-+
-+ Our goal here is to ensure that any two blocks that contain dependent modifications

-+ fusion whenever a transaction handle belonging to one atom requests to read or write a
-+ block belonging to another atom (TXN_CAPTURE_WRITE or TXN_CAPTURE_READ_ATOMIC).
-+
-+ In addition, this routine handles the initial assignment of atoms to blocks and
-+ transaction handles. These are possible outcomes of this function:
-+
-+ 1. The block and handle are already part of the same atom: return immediate success
-+
-+ 2. The block is assigned but the handle is not: call capture_assign_txnh to assign
-+ the handle to the block's atom.
-+
-+ 3. The handle is assigned but the block is not: call capture_assign_block to assign
-+ the block to the handle's atom.
-+
-+ 4. Both handle and block are assigned, but to different atoms: call capture_init_fusion
-+ to fuse atoms.
-+
-+ 5. Neither block nor handle are assigned: create a new atom and assign them both.
-+
-+ 6. A read request for a non-captured block: return immediate success.
-+
-+ This function acquires and releases the handle's spinlock. This function is called
-+ under the jnode lock and if the return value is 0, it returns with the jnode lock still
-+ held. If the return is -E_REPEAT or some other error condition, the jnode lock is
-+ released. The external interface (try_capture) manages re-aquiring the jnode lock

-+/* A note on lock ordering: the handle & jnode spinlock protects reading of their ->atom
-+ fields, so typically an operation on the atom through either of these objects must (1)
-+ lock the object, (2) read the atom pointer, (3) lock the atom.
-+
-+ During atom fusion, the process holds locks on both atoms at once. Then, it iterates
-+ through the list of handles and pages held by the smaller of the two atoms. For each
-+ handle and page referencing the smaller atom, the fusing process must: (1) lock the
-+ object, and (2) update the atom pointer.
-+
-+ You can see that there is a conflict of lock ordering here, so the more-complex
-+ procedure should have priority, i.e., the fusing process has priority so that it is
-+ guaranteed to make progress and to avoid restarts.
-+
-+ This decision, however, means additional complexity for aquiring the atom lock in the
-+ first place.
-+
-+ The general original procedure followed in the code was:
-+
-+ TXN_OBJECT *obj = ...;
-+ TXN_ATOM *atom;
-+
-+ spin_lock (& obj->_lock);
-+
-+ atom = obj->_atom;
-+
-+ if (! spin_trylock_atom (atom))
-+ {
-+ spin_unlock (& obj->_lock);
-+ RESTART OPERATION, THERE WAS A RACE;
-+ }
-+
-+ ELSE YOU HAVE BOTH ATOM AND OBJ LOCKED
-+
-+ It has however been found that this wastes CPU a lot in a manner that is
-+ hard to profile. So, proper refcounting was added to atoms, and new
-+ standard locking sequence is like following:
-+
-+ TXN_OBJECT *obj = ...;
-+ TXN_ATOM *atom;
-+
-+ spin_lock (& obj->_lock);
-+
-+ atom = obj->_atom;
-+
-+ if (! spin_trylock_atom (atom))
-+ {
-+ atomic_inc (& atom->refcount);
-+ spin_unlock (& obj->_lock);
-+ spin_lock (&atom->_lock);
-+ atomic_dec (& atom->refcount);

-+/* Step 3: Use TYPE_SAFE_HASH_DEFINE to define the hash table interface using
-+ the type and field name used in step 3. The arguments are:
-+
-+ ITEM_TYPE The item type being hashed
-+ KEY_TYPE The type of key being hashed
-+ KEY_NAME The name of the key field within the item
-+ LINK_NAME The name of the link field within the item, which you must make type PREFIX_hash_link)
-+ HASH_FUNC The name of the hash function (or macro, takes const pointer to key)
-+ EQ_FUNC The name of the equality function (or macro, takes const pointer to two keys)
-+
-+ It implements these functions:
-+
-+ prefix_hash_init Initialize the table given its size.
-+ prefix_hash_insert Insert an item
-+ prefix_hash_insert_index Insert an item w/ precomputed hash_index
-+ prefix_hash_find Find an item by key
-+ prefix_hash_find_index Find an item w/ precomputed hash_index
-+ prefix_hash_remove Remove an item, returns 1 if found, 0 if not found
-+ prefix_hash_remove_index Remove an item w/ precomputed hash_index
-+
-+ If you'd like something to be done differently, feel free to ask me
-+ for modifications. Additional features that could be added but
-+ have not been:
-+
-+ prefix_hash_remove_key Find and remove an item by key
-+ prefix_hash_remove_key_index Find and remove an item by key w/ precomputed hash_index
-+
-+ The hash_function currently receives only the key as an argument,
-+ meaning it must somehow know the number of buckets. If this is a
-+ problem let me know.
-+
-+ This hash table uses a single-linked hash chain. This means
-+ insertion is fast but deletion requires searching the chain.
-+
-+ There is also the doubly-linked hash chain approach, under which
-+ deletion requires no search but the code is longer and it takes two
-+ pointers per item.
-+
-+ The circularly-linked approach has the shortest code but requires
-+ two pointers per bucket, doubling the size of the bucket array (in
-+ addition to two pointers per item).

-+/* Reiser4 Wandering Log */
-+
-+/* You should read http://www.namesys.com/txn-doc.html
-+
-+ That describes how filesystem operations are performed as atomic
-+ transactions, and how we try to arrange it so that we can write most of the
-+ data only once while performing the operation atomically.
-+
-+ For the purposes of this code, it is enough for it to understand that it
-+ has been told a given block should be written either once, or twice (if
-+ twice then once to the wandered location and once to the real location).
-+
-+ This code guarantees that those blocks that are defined to be part of an
-+ atom either all take effect or none of them take effect.
-+
-+ Relocate set nodes are submitted to write by the jnode_flush() routine, and
-+ the overwrite set is submitted by reiser4_write_log(). This is because with
-+ the overwrite set we seek to optimize writes, and with the relocate set we
-+ seek to cause disk order to correlate with the parent first pre-order.
-+
-+ reiser4_write_log() allocates and writes wandered blocks and maintains
-+ additional on-disk structures of the atom as wander records (each wander
-+ record occupies one block) for storing of the "wandered map" (a table which
-+ contains a relation between wandered and real block numbers) and other
-+ information which might be needed at transaction recovery time.
-+
-+ The wander records are unidirectionally linked into a circle: each wander
-+ record contains a block number of the next wander record, the last wander
-+ record points to the first one.
-+
-+ One wander record (named "tx head" in this file) has a format which is
-+ different from the other wander records. The "tx head" has a reference to the
-+ "tx head" block of the previously committed atom. Also, "tx head" contains
-+ fs information (the free blocks counter, and the oid allocator state) which
-+ is logged in a special way .
-+
-+ There are two journal control blocks, named journal header and journal
-+ footer which have fixed on-disk locations. The journal header has a
-+ reference to the "tx head" block of the last committed atom. The journal
-+ footer points to the "tx head" of the last flushed atom. The atom is
-+ "played" when all blocks from its overwrite set are written to disk the
-+ second time (i.e. written to their real locations).
-+
-+ NOTE: People who know reiserfs internals and its journal structure might be
-+ confused with these terms journal footer and journal header. There is a table
-+ with terms of similar semantics in reiserfs (reiser3) and reiser4:
-+
-+ REISER3 TERM | REISER4 TERM | DESCRIPTION
-+ --------------------+-----------------------+----------------------------
-+ commit record | journal header | atomic write of this record
-+ | | ends transaction commit
-+ --------------------+-----------------------+----------------------------
-+ journal header | journal footer | atomic write of this record
-+ | | ends post-commit writes.
-+ | | After successful
-+ | | writing of this journal
-+ | | blocks (in reiser3) or
-+ | | wandered blocks/records are
-+ | | free for re-use.
-+ --------------------+-----------------------+----------------------------
-+
-+ The atom commit process is the following:
-+
-+ 1. The overwrite set is taken from atom's clean list, and its size is
-+ counted.
-+
-+ 2. The number of necessary wander records (including tx head) is calculated,
-+ and the wander record blocks are allocated.
-+
-+ 3. Allocate wandered blocks and populate wander records by wandered map.
-+
-+ 4. submit write requests for wander records and wandered blocks.
-+
-+ 5. wait until submitted write requests complete.
-+
-+ 6. update journal header: change the pointer to the block number of just
-+ written tx head, submit an i/o for modified journal header block and wait
-+ for i/o completion.
-+
-+ NOTE: The special logging for bitmap blocks and some reiser4 super block
-+ fields makes processes of atom commit, flush and recovering a bit more
-+ complex (see comments in the source code for details).
-+
-+ The atom playing process is the following:
-+
-+ 1. Write atom's overwrite set in-place.
-+
-+ 2. Wait on i/o.
-+
-+ 3. Update journal footer: change the pointer to block number of tx head
-+ block of the atom we currently flushing, submit an i/o, wait on i/o
-+ completion.
-+
-+ 4. Free disk space which was used for wandered blocks and wander records.
-+
-+ After the freeing of wandered blocks and wander records we have that journal
-+ footer points to the on-disk structure which might be overwritten soon.
-+ Neither the log writer nor the journal recovery procedure use that pointer
-+ for accessing the data. When the journal recovery procedure finds the oldest
-+ transaction it compares the journal footer pointer value with the "prev_tx"
-+ pointer value in tx head, if values are equal the oldest not flushed
-+ transaction is found.
-+
-+ NOTE on disk space leakage: the information about of what blocks and how many
-+ blocks are allocated for wandered blocks, wandered records is not written to
-+ the disk because of special logging for bitmaps and some super blocks
-+ counters. After a system crash we the reiser4 does not remember those
-+ objects allocation, thus we have no such a kind of disk space leakage.
-+*/
-+
-+/* Special logging of reiser4 super block fields. */
-+
-+/* There are some reiser4 super block fields (free block count and OID allocator
-+ state (number of files and next free OID) which are logged separately from
-+ super block to avoid unnecessary atom fusion.
-+
-+ So, the reiser4 super block can be not captured by a transaction with
-+ allocates/deallocates disk blocks or create/delete file objects. Moreover,
-+ the reiser4 on-disk super block is not touched when such a transaction is
-+ committed and flushed. Those "counters logged specially" are logged in "tx
-+ head" blocks and in the journal footer block.
-+
-+ A step-by-step description of special logging:
-+
-+ 0. The per-atom information about deleted or created files and allocated or
-+ freed blocks is collected during the transaction. The atom's
-+ ->nr_objects_created and ->nr_objects_deleted are for object
-+ deletion/creation tracking, the numbers of allocated and freed blocks are
-+ calculated using atom's delete set and atom's capture list -- all new and
-+ relocated nodes should be on atom's clean list and should have JNODE_RELOC
-+ bit set.
-+
-+ 1. The "logged specially" reiser4 super block fields have their "committed"
-+ versions in the reiser4 in-memory super block. They get modified only at
-+ atom commit time. The atom's commit thread has an exclusive access to those
-+ "committed" fields because the log writer implementation supports only one
-+ atom commit a time (there is a per-fs "commit" semaphore). At
-+ that time "committed" counters are modified using per-atom information
-+ collected during the transaction. These counters are stored on disk as a
-+ part of tx head block when atom is committed.
-+
-+ 2. When the atom is flushed the value of the free block counter and the OID
-+ allocator state get written to the journal footer block. A special journal
-+ procedure (journal_recover_sb_data()) takes those values from the journal
-+ footer and updates the reiser4 in-memory super block.
-+
-+ NOTE: That means free block count and OID allocator state are logged
-+ separately from the reiser4 super block regardless of the fact that the
-+ reiser4 super block has fields to store both the free block counter and the
-+ OID allocator.
-+
-+ Writing the whole super block at commit time requires knowing true values of
-+ all its fields without changes made by not yet committed transactions. It is
-+ possible by having their "committed" version of the super block like the
-+ reiser4 bitmap blocks have "committed" and "working" versions. However,
-+ another scheme was implemented which stores special logged values in the
-+ unused free space inside transaction head block. In my opinion it has an
-+ advantage of not writing whole super block when only part of it was
-+ modified. */

-+/* Znode manipulation functions. */
-+/* Znode is the in-memory header for a tree node. It is stored
-+ separately from the node itself so that it does not get written to
-+ disk. In this respect znode is like buffer head or page head. We
-+ also use znodes for additional reiser4 specific purposes:
-+
-+ . they are organized into tree structure which is a part of whole
-+ reiser4 tree.
-+ . they are used to implement node grained locking
-+ . they are used to keep additional state associated with a
-+ node
-+ . they contain links to lists used by the transaction manager
-+
-+ Znode is attached to some variable "block number" which is instance of
-+ fs/reiser4/tree.h:reiser4_block_nr type. Znode can exist without
-+ appropriate node being actually loaded in memory. Existence of znode itself
-+ is regulated by reference count (->x_count) in it. Each time thread
-+ acquires reference to znode through call to zget(), ->x_count is
-+ incremented and decremented on call to zput(). Data (content of node) are
-+ brought in memory through call to zload(), which also increments ->d_count
-+ reference counter. zload can block waiting on IO. Call to zrelse()
-+ decreases this counter. Also, ->c_count keeps track of number of child
-+ znodes and prevents parent znode from being recycled until all of its
-+ children are. ->c_count is decremented whenever child goes out of existence
-+ (being actually recycled in zdestroy()) which can be some time after last
-+ reference to this child dies if we support some form of LRU cache for
-+ znodes.
-+
-+*/
-+/* EVERY ZNODE'S STORY
-+
-+ 1. His infancy.
-+
-+ Once upon a time, the znode was born deep inside of zget() by call to
-+ zalloc(). At the return from zget() znode had:
-+
-+ . reference counter (x_count) of 1
-+ . assigned block number, marked as used in bitmap
-+ . pointer to parent znode. Root znode parent pointer points
-+ to its father: "fake" znode. This, in turn, has NULL parent pointer.
-+ . hash table linkage
-+ . no data loaded from disk
-+ . no node plugin
-+ . no sibling linkage
-+
-+ 2. His childhood
-+
-+ Each node is either brought into memory as a result of tree traversal, or
-+ created afresh, creation of the root being a special case of the latter. In
-+ either case it's inserted into sibling list. This will typically require
-+ some ancillary tree traversing, but ultimately both sibling pointers will
-+ exist and JNODE_LEFT_CONNECTED and JNODE_RIGHT_CONNECTED will be true in
-+ zjnode.state.
-+
-+ 3. His youth.
-+
-+ If znode is bound to already existing node in a tree, its content is read
-+ from the disk by call to zload(). At that moment, JNODE_LOADED bit is set
-+ in zjnode.state and zdata() function starts to return non null for this
-+ znode. zload() further calls zparse() that determines which node layout
-+ this node is rendered in, and sets ->nplug on success.
-+
-+ If znode is for new node just created, memory for it is allocated and
-+ zinit_new() function is called to initialise data, according to selected
-+ node layout.
-+
-+ 4. His maturity.
-+
-+ After this point, znode lingers in memory for some time. Threads can
-+ acquire references to znode either by blocknr through call to zget(), or by
-+ following a pointer to unallocated znode from internal item. Each time
-+ reference to znode is obtained, x_count is increased. Thread can read/write
-+ lock znode. Znode data can be loaded through calls to zload(), d_count will
-+ be increased appropriately. If all references to znode are released
-+ (x_count drops to 0), znode is not recycled immediately. Rather, it is
-+ still cached in the hash table in the hope that it will be accessed
-+ shortly.
-+
-+ There are two ways in which znode existence can be terminated:
-+
-+ . sudden death: node bound to this znode is removed from the tree
-+ . overpopulation: znode is purged out of memory due to memory pressure
-+
-+ 5. His death.
-+
-+ Death is complex process.
-+
-+ When we irrevocably commit ourselves to decision to remove node from the
-+ tree, JNODE_HEARD_BANSHEE bit is set in zjnode.state of corresponding
-+ znode. This is done either in ->kill_hook() of internal item or in
-+ kill_root() function when tree root is removed.
-+
-+ At this moment znode still has:
-+
-+ . locks held on it, necessary write ones
-+ . references to it
-+ . disk block assigned to it
-+ . data loaded from the disk
-+ . pending requests for lock
-+
-+ But once JNODE_HEARD_BANSHEE bit set, last call to unlock_znode() does node
-+ deletion. Node deletion includes two phases. First all ways to get
-+ references to that znode (sibling and parent links and hash lookup using
-+ block number stored in parent node) should be deleted -- it is done through
-+ sibling_list_remove(), also we assume that nobody uses down link from
-+ parent node due to its nonexistence or proper parent node locking and
-+ nobody uses parent pointers from children due to absence of them. Second we
-+ invalidate all pending lock requests which still are on znode's lock
-+ request queue, this is done by invalidate_lock(). Another JNODE_IS_DYING
-+ znode status bit is used to invalidate pending lock requests. Once it set
-+ all requesters are forced to return -EINVAL from
-+ longterm_lock_znode(). Future locking attempts are not possible because all
-+ ways to get references to that znode are removed already. Last, node is
-+ uncaptured from transaction.
-+
-+ When last reference to the dying znode is just about to be released,
-+ block number for this lock is released and znode is removed from the
-+ hash table.
-+
-+ Now znode can be recycled.
-+
-+ [it's possible to free bitmap block and remove znode from the hash
-+ table when last lock is released. This will result in having
-+ referenced but completely orphaned znode]
-+
-+ 6. Limbo
-+
-+ As have been mentioned above znodes with reference counter 0 are
-+ still cached in a hash table. Once memory pressure increases they are
-+ purged out of there [this requires something like LRU list for
-+ efficient implementation. LRU list would also greatly simplify
-+ implementation of coord cache that would in this case morph to just
-+ scanning some initial segment of LRU list]. Data loaded into
-+ unreferenced znode are flushed back to the durable storage if
-+ necessary and memory is freed. Znodes themselves can be recycled at
-+ this point too.

-Initial Package Version: 1.6.8p12
-Origin: Upstream CVS
-Upstream Status: In CVS
-Description: (CVE-2005-4158) Sudo before 1.6.8 p12, when the Perl taint flag is
- off, does not clear the PERLLIB, PERL5LIB, and PERL5OPT environment
- variables, which allows limited local users to cause a Perl script
- to include and execute arbitrary library files that have the same
- name as library files that are included by the script.
- Additionally, more variables beyond perl were added to the
- blacklist and comments were added to the variables.
