87 New and rewritten pages
88 -----------------------
91 Anna Schumaker [Darrick J. Wong, Christoph Hellwig, Michael Kerrisk]
92 New page documenting copy_file_range()
93 copy_file_range() is a new system call for copying ranges of data
94 completely in the kernel. This gives filesystems an opportunity to
95 implement some kind of "copy acceleration", such as reflinks or
96 server-side-copy (in the case of NFS).
100 This page has been greatly expanded, to add descriptions of
104 Michael Kerrisk [Adhemerval Zanella]
105 Significant reworking of this page:
106 * Rework discussion of the (obsolete) binary mode
107 * Split open_memstream(3) description into a separate page.
108 * Note various fmemopen() bugs that were fixed in glibc 2.22
109 * Greatly expand description of 'mode' argument
110 * Rework description of 'buf' and 'len' arguments
111 * Expand discussion of "current position" for fmemopen() stream
115 New page describing ntp_gettime(3) and ntp_gettimex(3)
119 New page created by split of fmemopen(3).
120 At the same time, add and rework a few details in the text.
123 Bill O. Gallmeister, Michael Kerrisk
124 New man page documenting posix_spawn(3) and posix_spawnp(3)
127 Michael Kerrisk [Florian Weimer]
128 Split readdir_r() content into separate page
129 As suggested by Florian Weimer:
131 It may make sense to move this documentation to a separate
132 manual page, specific to readdir_r. This will keep the
133 readdir() documentation nice and crisp. Most programmers
134 will never have to consult all these details.
136 Near complete restructuring of the page and add some further details
137 Michael Kerrisk [Florian Weimer, Rich Felker, Paul Eggert]
138 Add a lot more detail on portable use of the 'd_name' field
141 Michael Kerrisk [Florian Weimer]
142 New page created after split of readdir(3).
143 Michael Kerrisk [Florian Weimer]
144 Explain why readdir_r() is deprecated and readdir() is preferred
145 Michael Kerrisk [Florian Weimer]
146 Remove misleading code example using pathconf()
150 New page documenting lirc device driver
153 Newly documented interfaces in existing pages
154 ---------------------------------------------
158 Document ntp_adjtime(3)
161 Michael Kerrisk [Jason Baron]
162 Document EPOLLEXCLUSIVE
165 Minchan Kim [Michael Kerrisk]
167 Document the MADV_FREE flag added to madvise() in Linux 4.5.
171 Document CmaTotal and CmaFree fields of /proc/meminfo
173 Document additional /proc/meminfo fields
174 Document DirectMap4k, DirectMap4M, DirectMap2M, DirectMap1G
176 Document MemAvailable /proc/meminfo field
178 Document inotify /proc/PID/fdinfo entries
180 Document fanotify /proc/PID/fdinfo entries
182 Add some kernel version numbers for /proc/PID/fdinfo entries
183 Michael Kerrisk [Patrick Donnelly]
184 /proc/PID/fdinfo displays the setting of the close-on-exec flag
185 Note also the pre-3.1 bug in the display of this info.
188 Craig Gallek [Michael Kerrisk, Vincent Bernat]
189 Document some BPF-related socket options
190 Document the behavior and the first kernel version for each of the
191 following socket options:
195 SO_ATTACH_REUSEPORT_CBPF
196 SO_ATTACH_REUSEPORT_EBPF
202 New and changed links
203 ---------------------
207 New link to isalpha.3
211 Replace page with link to setjmp(3), which now incorporates longjmp()
215 New link to adjtimex(2)
219 New link to ntp_gettime.3
223 Update link to point to new open_memstream(2) page
227 New link to new posix_spawn.3 page
231 Rewire link to point to setjmp(3)
235 New link to strerror.3
244 Update FTM requirements (_DEFAULT_SOURCE)
246 Update feature test macro requirements
247 Update to use _DEFAULT_SOURCE, and also changes brought by
248 glibc commit 266865c0e7b79d4196e2cc393693463f03c90bd8.
252 Simplify FTM requirements
253 Looking at <features.h> (or feature_test_macros(7)), one can
254 see that when _XOPEN_SOURCE is defined with the value 700
255 (or greater), then _POSIX_C_SOURCE is defined with the value
256 200809L (or greater). Therefore, terms in the man pages such as
258 _XOPEN_SOURCE\ >=\ 700 || _POSIX_C_SOURCE\ >=\ 200809L
260 can be simplified to:
262 _POSIX_C_SOURCE\ >=\ 200809L
266 Simplify FTM requirements
267 Looking at <features.h> (or feature_test_macros(7)), one can
268 see that when _XOPEN_SOURCE is defined with the value 600
269 (or greater), then _POSIX_C_SOURCE is defined with the value
270 200112L (or greater). Therefore, terms in the man pages such as
272 _XOPEN_SOURCE\ >=\ 600 || _POSIX_C_SOURCE\ >=\ 200112L
274 can be simplified to:
276 _POSIX_C_SOURCE\ >=\ 200112L
280 Simplify FTM requirements
281 _XOPEN_SOURCE implies _POSIX_C_SOURCE >=2, so simplify FTM
282 requirements in various pages.
286 Remove "or 'cc -std=c99'" from SYNOPSIS
287 Under the FTM requirements all of these pages document the
288 requirement for _ISOC99_SOURCE. And feature_test_macros(7) now
289 documents that "cc -std=c99" produces the same effect as defining
290 _ISOC99_SOURCE. So, all of these pages don't additionally need
291 to specify "or 'cc -std=c99'" under the FTM requirements
292 in the SYNOPSIS. Removing that redundant text also simplifies
293 the SYNOPSIS a little.
297 Simplify FTM requirements
298 Looking at <features.h> (or feature_test_macros(7)), one can
299 see that when _XOPEN_SOURCE is defined with the value 600
300 (or greater), then _POSIX_C_SOURCE is defined with the value
301 200112L (or greater). Therefore, terms in the man pages such as
303 _XOPEN_SOURCE\ >=\ 600 || _POSIX_C_SOURCE\ >=\ 200112L
305 can be simplified to:
307 _POSIX_C_SOURCE\ >=\ 200112L
311 Remove references to _XOPEN_SOURCE_EXTENDED in SYNOPSIS
312 _XOPEN_SOURCE_EXTENDED is obsolete (it existed in SUSv1, but not
313 subsequent standards). _XOPEN_SOURCE >= 500 produces the same
314 effects as (_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED). Modifying
315 the SYNOPSIS of various ages that contain:
317 _XOPEN_SOURCE\ >=\ 500 ||
318 _XOPEN_SOURCE\ &&\ _XOPEN_SOURCE_EXTENDED
322 _XOPEN_SOURCE\ >=\ 500
324 This has the following benefits:
326 a) Simplifying the SYNOPSIS by removing ancient
327 historical information.
329 b) Preventing users from being misled into using
330 _XOPEN_SOURCE_EXTENDED in new source code.
334 Remove mention of the obsolete _POSIX_SOURCE macro from SYNOPSIS
335 _POSIX_SOURCE was a POSIX.1-1990 creation that was soon made
336 obsolete bu _POSIX_C_SOURCE. Retaining mention of it
337 in the feature test macro requirements section of the
338 SYNOPSIS doesn't contain important information, and may
339 mislead readers into actually trying to use this macro.
340 A few mentions of it are maintained in a some pages where
341 defining _POSIX_SOURCE inhibits some behavior.
343 Various sockets-related pages
344 Michael Kerrisk [Carlos O'Donell]
345 Use consistent argument/variable names for socket addresses and lengths
346 As noted by Carlos, there's quite a bit of inconsistency across
347 pages. Use 'addr' and 'addrlen' consistently in variables and
352 Wording fix: "current file offset" ==> "file offset"
353 "File offset" is the preferred POSIX terminology.
357 Word "descriptor" more precisely
358 Use either "file descriptor" or message queue descriptor".
362 ERRORS: add reference to signal(7) in description of EINTR
365 Changes to individual pages
366 ---------------------------
370 Add "locale -c charmap" as an example
371 Addresses https://bugzilla.kernel.org/show_bug.cgi?id=104511.
375 Add hint on purpose of --no-archive
376 Indicate why using --no-archive might be a good idea. The issue
377 is that if you create a custom locale with localedef(1) and put
378 it to the locale archive then during the next glibc upgrade the
379 locale archive is updated as well and your custom locale is gone.)
383 ERRORS: improve description for EBADF
386 Michael Kerrisk [John Stultz]
387 Various improvements after feedback from John Stultz
389 Remove FTM requirements
390 It seems that adjtimex() never needed _BSD_SOURCE (and my
391 earlier commit 5918743bc8b02b was simply a blunder).
393 Split EINVAL error cases
395 Note treatment of out-of-range buf.offset
397 Don't refer reader to adjtime(3)
398 Probably, it's not wise to suggest adjtime(3) as the more
399 portable API. Rather, ntp_adjtime(3) should be used.
400 Michael Kerrisk [Naresh Kamboju]
401 Update details of buf.offset EINVAL error
403 SEE ALSO: add ntp_gettime(3)
405 Improve description of some PPS timex fields
407 Add ATTRIBUTES section
408 William Preston [Petr Gajdos]
409 Update a detail in adjtimex return value description
411 Note range constraints and clamping for ADJ_FREQUENCY
415 Note that glibc support for this system call went away in version 2.23
419 Improve description of ENOENT error
423 Document close-on-exec semantics
424 The close-on-exec file descriptor flag is automatically enabled
425 for FDs returned by bpf().
429 Clarify terminology (file mode versus file permission bits)
433 ERRORS: improve EBADF description
438 Remove mention of _BSD_SOURCE and _SVID_SOURCE
439 The right way to expose declarations for these Linux-specific
440 system calls was always _GNU_SOURCE. Mentioning the historical
441 use of _BSD_SOURCE and _SVID_SOURCE just clouds the issue.
445 ERRORS: improve EBADF description
449 Glibc 2.23 removed last vestiges of support for this system call
453 Glibc 2.23 removed last vestiges of support for this system call
457 Document ELOOP error for circular monitoring loops
461 Note that eventfd info is available in /proc/PID/fdinfo
464 Michael Kerrisk [Krzysztof Adamski]
465 Add EPERM error for capabilities check of capability-dumb binaries
467 Add reference to ld-linux.so(8)
469 SEE ALSO: add system(3)
473 Note kernel version that allowed O_CLOEXEC for event_f_flags
478 SEE ALSO: add lslocks(8)
481 Michael Kerrisk [Jason Vas Dias]
482 Rework description of F_SETOWN
483 As suggested by Jason, make it clearer that I/O signalling
484 requires the use of both F_SETOWN and O_ASYNC. While we're at,
485 make a few other cleanups to the text.
487 Remove mention of _BSD_SOURCE to get definition of F_SETOWN/F_GETOWN
488 This usage went away in glibc 2.20, and the simplest remedy
489 is just to omit mention of it.
493 FUTEX_CLOCK_REALTIME can now be used with FUTEX_WAIT
497 Note that glibc des not support this system call
501 Glibc 2.23 removed last vestiges of support for this system call
505 Include uapi/linux/wireless.h
506 Add the list of wireless IOCTLs.
509 sockios.h is now in include/uapi
511 Add reference to netdevice.7
512 netdevice.7 describes most of the IOCTLs of sockios.h
514 Transfer structure (wireless.h IOCTLs)
515 The sole parameter to be passed to the wireless.h IOCTLs is
516 of type struct iwreq *.
519 Michael Kerrisk [Alex Henrie]
520 ioperm.2: Permissions are inherited across fork(2)
521 See https://bugzilla.kernel.org/show_bug.cgi?id=99911
524 Michael Kerrisk [Alex Henrie]
525 Permissions are not inherited across fork(2) or preserved on execve(2)
526 See https://bugzilla.kernel.org/show_bug.cgi?id=99901
530 FUSE now supports SEEK_HOLE and SEEK_DATA
532 NFS supports SEEK_HOLE and SEEK_DATA
535 SEE ALSO: add open(2)
539 Clarify MADV_HWPOISON wording to say that it applies to a page range
543 SEE ALSO: add mknod(1)
547 SEE ALSO: add findmnt(8)
551 NOTES: mention existence of proc/PID/fd and /proc/PID/fdinfo
552 Mark Post [Petr Gajdos]
553 O_TMPFILE support is now provided bt Btrfs
556 Michael Kerrisk [Eric Blake]
557 Note treatment of 'pipefd' on error
560 Michael Kerrisk [Josh Triplett]
561 Document spurious EAGAIN error that can occur on other systems
562 Light reworking of text proposed by Josh Triplett.
566 Clarify EINVAL error description
570 Equivalence to read()
571 Describe the recv(2)-read(2) and the recvfrom(2)-recv(2)
572 equivalences for zero-valued arguments.
574 MSG_WAITALL has no effect for datagram sockets
579 Fix type of cmsg_len member of cmsghdr structure
580 The type shown for cmsg_len member of cmsghdr structure is socklen_t,
581 but the actual type used by glibc and the kernel is size_t.
582 The information was obtained from glibc source code:
583 http://bit.ly/21m1RMp
585 Note that cmsg_len is typed as socklen_t in POSIX.1
589 Michael Kerrisk [Florian Weimer, Florian Weimer]
590 Warn that CPU_ALLOC() may allocate a slightly CPU set than requested
591 Michael Kerrisk [Florian Weimer]
592 Add reference to CPU_ALLOC(3)
595 Michael Kerrisk [Akihiro Suda]
596 EPERM depends on affinity mask of target thread, not calling thread
599 Michael Kerrisk [Josh Triplett]
600 Document spurious EAGAIN error that can occur on other systems
601 Light reworking of text proposed by Josh Triplett.
602 Nikos Mavrogiannopoulos
603 Mention the 'fd_set' size limitation early and refer to poll(2)
604 Change this because of the serious limitation of select()
605 imposing a limit on the range of file descriptors that can
606 be monitored. This is currently mentioned too late in the
607 documentation (in the NOTES section). The man page should
608 warn early and refer to poll(2) as soon as possible.
610 Add details on the glibc fixed-size fd_set limitation
611 No modern application should use select() on Linux.
615 Some readability fixes to example program
617 Better variable names in example program
619 Simplify 'if' logic in in example program
621 Use correct type (socklen_t) for addrlen
624 Michael Kerrisk [Davidlohr Bueso, Manfred Spraul, Philip Semanchuk]
625 NOTES: note when 'sempid' is set on various implementations
626 See https://bugzilla.kernel.org/show_bug.cgi?id=112271 and
627 http://thread.gmane.org/gmane.linux.kernel/2162754/
628 Subject: [PATCH] Don't set sempid in semctl syscall.
629 Date: 2016-02-26 12:21:38 GMT
633 Tweak comment describing 'sempid'
637 Fix incorrect description in text referring to splice(2)
639 SEE ALSO: add copy_file_range(2)
643 Correct/simplify FTM requirements for BSD setpgrp() and getpgrp()
647 Note that signalfd info is available in /proc/PID/fdinfo
650 Michael Kerrisk [Mike Frysinger]
651 Explicitly refer the reader to sigsetops(3)
652 This man page did not make it obvious which functions
653 should be used for manipulating signals sets, nor where
654 those functions were documented.
657 Michael Kerrisk [Eric Blake]
658 Note treatment of 'sv' on error
662 Improve description of 0 return value.
663 See https://bugzilla.kernel.org/show_bug.cgi?id=90911
666 Michael Kerrisk [Jakub Wilk]
667 Use consistent case for hex constants
671 Clarify description and document the Linux data integrity guarantees
675 Add more architectures and improve error documentation
676 Move the error register documentation into the main table rather
677 than listing them in sentences after the fact.
679 Add sparc error return details.
681 Add details for alpha/arc/m68k/microblaze/nios2/powerpc/superh/
686 Add copy_file_range(2)
690 Fix an incorrect description in NOTES
691 The text has an incorrect description in NOTES, it says
692 that (2^32/HZ) - 300 is about 429 million. It is correct
693 only if HZ=10 which does not look common today. So just
694 removing "(i.e., about 429 million)" is good enough.
698 SEE ALSO: add truncate(1)
702 Mention CONFIG_USELIB
704 Note that glibc does not support this (obsolete) system call
709 Rename the "status" argument to "wstatus"
710 The fact that exit(3)/_exit(2) has an argument called
711 "status" and the same name is used in the arguments to the
712 wait*() calls can a little too easily lead the user into
713 thinking that the two arguments hold the same information,
714 when of course they don't. So, use a different name
715 for the argument of the wait*() functions, to reduce
716 the chances of such confusion.
719 Michael Kerrisk [Martin Gebert]
720 Small fixes to example program
723 Michael Kerrisk [Matt Zimmerman]
724 Clarify the use and effect of clearenv()
725 See http://bugs.debian.org/679323
727 Variables can be added to the environment after calling clearenv()
731 Show an alternative equivalence for clog10()
734 Fix grammar error and add C11.

765 Michael Kerrisk [Alan Cox]
766 gamma() was documented in SVID 2
769 Michael Kerrisk [Andreas Schwab, Orion Poplawski]
770 Update FTM requirements for glibc 2.22
771 Since glibc 2.22 getaddrinfo() etc. are only declared for
772 POSIX.1-2001 or later.
780 Help the reader by explicitly mentioning the use of readdir(3)
784 Suggest use of strerror(3) in place of deprecated 'sys_errlist'
789 The glibc implementation of posix_fallocate(), which calls
790 fallocate(), may be interrupted. The fallocate() emulation
791 also makes use of pread()/pwrite(), which may also be
795 Michael Kerrisk [Eric Blake]
796 Note posix_memalign()'s treatment of 'memptr' on error
798 pthread_setaffinity_np.3
800 SEE ALSO: add CPU_SET(3)
804 Remove double CONFORMING TO section
808 Add missing condition concerning .rhosts file
809 The list of conditions determining if iruserok() and ruserok()
810 functions automatically fail is incomplete. According to glibc
811 source code, the functions also fail if the .rhosts file
812 is hard linked anywhere.
816 SEE ALSO: add stdbuf(1)
820 Rewrite and merge longjmp()/siglongjmp() discussion into this page
821 The discussion of nonlocal gotos is much easier to read if
822 setjmp() and longjmp() are discussed in the same page. While
823 we're at it, rework almost the entire text and add several
826 Note the interactions of longjmp() and non-async-signal-safe functions
827 POSIX.1-2008 TC2 adds explicit text on this point.
828 See http://austingroupbugs.net/view.php?id=516#c1195
830 Explain why nonlocal gotos make code harder to maintain
832 Reword warning on longjmp() to function that has already returned
834 Remove reference to obsolete _XOPEN_SOURCE_EXTENDED
838 SEE ALSO: add sleep(1)

861 Further improvements to recent tweaks of canonical mode 4096 char limit
864 Michael Kerrisk [Stephen Hurd, Mats Wichmann]
865 Remove sample implementation of timegm()
