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 , or to ++Gilles Vollant 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 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 ++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.

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 ++ ++ ++Acknowledgments: ++ ++ The deflate format used by zlib was defined by Phil Katz.

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. ++ * ++ * REFERENCES ++ * ++ * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". ++ * Available in ftp://ds.internic.net/rfc/rfc1951.txt ++ * ++ * A description of the Rabin and Karp algorithm is given in the book ++ * "Algorithms" by R.

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 , 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.

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 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. ++ +--- /dev/null Tue Mar 11 13:02:56 2003 ++++ linux/net/ipsec/des/cbc_enc.c Mon Feb 9 13:51:03 2004 +@@ -0,0 +1,135 @@ ++/* crypto/des/cbc_enc.c */ ++/* Copyright (C) 1995-1997 Eric Young (eay@cryptsoft.com) ++ * All rights reserved. ++ * ++ * This package is an SSL implementation written ++ * by Eric Young (eay@cryptsoft.com). ++ * The implementation was written so as to conform with Netscapes SSL. ++ * ++ * This library is free for commercial and non-commercial use as long as ++ * the following conditions are aheared to.

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. +--- /dev/null Tue Mar 11 13:02:56 2003 ++++ linux/net/ipsec/des/des_enc.c Mon Feb 9 13:51:03 2004 +@@ -0,0 +1,502 @@ ++/* crypto/des/des_enc.c */ ++/* Copyright (C) 1995-1997 Eric Young (eay@cryptsoft.com) ++ * All rights reserved. ++ * ++ * This package is an SSL implementation written ++ * by Eric Young (eay@cryptsoft.com). ++ * The implementation was written so as to conform with Netscapes SSL. ++ * ++ * This library is free for commercial and non-commercial use as long as ++ * the following conditions are aheared to.

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. ++ */ ++ ++ ++void inflate_blocks_reset(s, z, c) ++inflate_blocks_statef *s; ++z_streamp z; ++uLongf *c; ++{ ++ if (c != Z_NULL) ++ *c = s->check; ++ if (s->mode == BTREE || s->mode == DTREE) ++ ZFREE(z, s->sub.trees.blens); ++ if (s->mode == CODES) ++ inflate_codes_free(s->sub.decode.codes, z); ++ s->mode = TYPE; ++ s->bitk = 0; ++ s->bitb = 0; ++ s->read = s->write = s->window; ++ if (s->checkfn != Z_NULL) ++ z->adler = s->check = (*s->checkfn)(0L, (const Bytef *)Z_NULL, 0); ++ Tracev((stderr, "inflate: blocks reset\n")); ++} ++ ++ ++inflate_blocks_statef *inflate_blocks_new(z, c, w) ++z_streamp z; ++check_func c; ++uInt w; ++{ ++ inflate_blocks_statef *s; ++ ++ if ((s = (inflate_blocks_statef *)ZALLOC ++ (z,1,sizeof(struct inflate_blocks_state))) == Z_NULL) ++ return s; ++ if ((s->hufts = ++ (inflate_huft *)ZALLOC(z, sizeof(inflate_huft), MANY)) == Z_NULL) ++ { ++ ZFREE(z, s); ++ return Z_NULL; ++ } ++ if ((s->window = (Bytef *)ZALLOC(z, 1, w)) == Z_NULL) ++ { ++ ZFREE(z, s->hufts); ++ ZFREE(z, s); ++ return Z_NULL; ++ } ++ s->end = s->window + w; ++ s->checkfn = c; ++ s->mode = TYPE; ++ Tracev((stderr, "inflate: blocks allocated\n")); ++ inflate_blocks_reset(s, z, Z_NULL); ++ return s; ++} ++ ++ ++int inflate_blocks(s, z, r) ++inflate_blocks_statef *s; ++z_streamp z; ++int r; ++{ ++ uInt t; /* temporary storage */ ++ uLong b; /* bit buffer */ ++ uInt k; /* bits in bit buffer */ ++ Bytef *p; /* input data pointer */ ++ uInt n; /* bytes available there */ ++ Bytef *q; /* output window write pointer */ ++ uInt m; /* bytes to end of window or read pointer */ ++ ++ /* copy input/output information to locals (UPDATE macro restores) */ ++ LOAD ++ ++ /* process input based on current state */ ++ while (1) switch (s->mode) ++ { ++ case TYPE: ++ NEEDBITS(3) ++ t = (uInt)b & 7; ++ s->last = t & 1; ++ switch (t >> 1) ++ { ++ case 0: /* stored */ ++ Tracev((stderr, "inflate: stored block%s\n", ++ s->last ?

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.

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 ++ * node as high in the tree as we can go. ++ */ ++ ++struct radij_node * ++rj_search(v_arg, head) ++ void *v_arg; ++ struct radij_node *head; ++{ ++ register struct radij_node *x; ++ register caddr_t v; ++ ++ for (x = head, v = v_arg; x->rj_b >= 0;) { ++ if (x->rj_bmask & v[x->rj_off]) ++ x = x->rj_r; ++ else ++ x = x->rj_l; ++ } ++ return (x); ++}; ++ ++struct radij_node * ++rj_search_m(v_arg, head, m_arg) ++ struct radij_node *head; ++ void *v_arg, *m_arg; ++{ ++ register struct radij_node *x; ++ register caddr_t v = v_arg, m = m_arg; ++ ++ for (x = head; x->rj_b >= 0;) { ++ if ((x->rj_bmask & m[x->rj_off]) && ++ (x->rj_bmask & v[x->rj_off])) ++ x = x->rj_r; ++ else ++ x = x->rj_l; ++ } ++ return x; ++}; ++ ++int ++rj_refines(m_arg, n_arg) ++ void *m_arg, *n_arg; ++{ ++ register caddr_t m = m_arg, n = n_arg; ++ register caddr_t lim, lim2 = lim = n + *(u_char *)n; ++ int longer = (*(u_char *)n++) - (int)(*(u_char *)m++); ++ int masks_are_equal = 1; ++ ++ if (longer > 0) ++ lim -= longer; ++ while (n < lim) { ++ if (*n & ~(*m)) ++ return 0; ++ if (*n++ != *m++) ++ masks_are_equal = 0; ++ ++ } ++ while (n < lim2) ++ if (*n++) ++ return 0; ++ if (masks_are_equal && (longer < 0)) ++ for (lim2 = m - longer; m < lim2; ) ++ if (*m++) ++ return 1; ++ return (!masks_are_equal); ++} ++ ++ ++struct radij_node * ++rj_match(v_arg, head) ++ void *v_arg; ++ struct radij_node_head *head; ++{ ++ caddr_t v = v_arg; ++ register struct radij_node *t = head->rnh_treetop, *x; ++ register caddr_t cp = v, cp2, cp3; ++ caddr_t cplim, mstart; ++ struct radij_node *saved_t, *top = t; ++ int off = t->rj_off, vlen = *(u_char *)cp, matched_off; ++ ++ /* ++ * Open code rj_search(v, top) to avoid overhead of extra ++ * subroutine call. ++ */ ++ for (; t->rj_b >= 0; ) { ++ if (t->rj_bmask & cp[t->rj_off]) ++ t = t->rj_r; ++ else ++ t = t->rj_l; ++ } ++ /* ++ * See if we match exactly as a host destination ++ */ ++ KLIPS_PRINT(debug_radij, ++ "klips_debug:rj_match: " ++ "* See if we match exactly as a host destination\n"); ++ ++ cp += off; cp2 = t->rj_key + off; cplim = v + vlen; ++ for (; cp < cplim; cp++, cp2++) ++ if (*cp != *cp2) ++ goto on1; ++ /* ++ * This extra grot is in case we are explicitly asked ++ * to look up the default.
