New and rewritten pages ----------------------- -copy_file_range.2 - Anna Schumaker [Darrick J. Wong, Christoph Hellwig, Michael Kerrisk] - New page documenting copy_file_range() - copy_file_range() is a new system call for copying ranges of data - completely in the kernel. This gives filesystems an opportunity to - implement some kind of "copy acceleration", such as reflinks or - server-side-copy (in the case of NFS). - -personality.2 - Michael Kerrisk - This page has been greatly expanded, to add descriptions of - personality domains. - -fmemopen.3 - Michael Kerrisk [Adhemerval Zanella] - Significant reworking of this page: - * Rework discussion of the (obsolete) binary mode - * Split open_memstream(3) description into a separate page. - * Note various fmemopen() bugs that were fixed in glibc 2.22 - * Greatly expand description of 'mode' argument - * Rework description of 'buf' and 'len' arguments - * Expand discussion of "current position" for fmemopen() stream - -ntp_gettime.3 - Michael Kerrisk - New page describing ntp_gettime(3) and ntp_gettimex(3) - -open_memstream.3 - Michael Kerrisk - New page created by split of fmemopen(3). - At the same time, add and rework a few details in the text. - -posix_spawn.3 - Bill O. Gallmeister, Michael Kerrisk - New man page documenting posix_spawn(3) and posix_spawnp(3) - -readdir.3 - Michael Kerrisk [Florian Weimer] - Split readdir_r() content into separate page - As suggested by Florian Weimer: - - It may make sense to move this documentation to a separate - manual page, specific to readdir_r. This will keep the - readdir() documentation nice and crisp. Most programmers - will never have to consult all these details. - Michael Kerrisk - Near complete restructuring of the page and add some further details - Michael Kerrisk [Florian Weimer, Rich Felker, Paul Eggert] - Add a lot more detail on portable use of the 'd_name' field - -readdir_r.3 - Michael Kerrisk [Florian Weimer] - New page created after split of readdir(3). - Michael Kerrisk [Florian Weimer] - Explain why readdir_r() is deprecated and readdir() is preferred - Michael Kerrisk [Florian Weimer] - Remove misleading code example using pathconf() - -lirc.4 - Alec Leamas - New page documenting lirc device driver - Newly documented interfaces in existing pages --------------------------------------------- -adjtimex.2 - Michael Kerrisk - Document ntp_adjtime(3) - -epoll_ctl.2 - Michael Kerrisk [Jason Baron] - Document EPOLLEXCLUSIVE - -madvise.2 - Minchan Kim [Michael Kerrisk] - Document MADV_FREE - Document the MADV_FREE flag added to madvise() in Linux 4.5. - -proc.5 - Michael Kerrisk - Document CmaTotal and CmaFree fields of /proc/meminfo - Michael Kerrisk - Document additional /proc/meminfo fields - Document DirectMap4k, DirectMap4M, DirectMap2M, DirectMap1G - Michael Kerrisk - Document MemAvailable /proc/meminfo field - Michael Kerrisk - Document inotify /proc/PID/fdinfo entries - Michael Kerrisk - Document fanotify /proc/PID/fdinfo entries - Michael Kerrisk - Add some kernel version numbers for /proc/PID/fdinfo entries - Michael Kerrisk [Patrick Donnelly] - /proc/PID/fdinfo displays the setting of the close-on-exec flag - Note also the pre-3.1 bug in the display of this info. - -socket.7 - Craig Gallek [Michael Kerrisk, Vincent Bernat] - Document some BPF-related socket options - Document the behavior and the first kernel version for each of the - following socket options: - - SO_ATTACH_FILTER - SO_ATTACH_BPF - SO_ATTACH_REUSEPORT_CBPF - SO_ATTACH_REUSEPORT_EBPF - SO_DETACH_FILTER - SO_DETACH_BPF - SO_LOCK_FILTER - New and changed links --------------------- -isalpha_l.3 - Michael Kerrisk - New link to isalpha.3 - -longjmp.3 - Michael Kerrisk - Replace page with link to setjmp(3), which now incorporates longjmp() - -ntp_adjtime.3 - Michael Kerrisk - New link to adjtimex(2) - -ntp_gettimex.3 - Michael Kerrisk - New link to ntp_gettime.3 - -open_wmemstream.3 - Michael Kerrisk - Update link to point to new open_memstream(2) page - -posix_spawnp.3 - Michael Kerrisk - New link to new posix_spawn.3 page - -siglongjmp.3 - Michael Kerrisk - Rewire link to point to setjmp(3) - -strerror_l.3 - Michael Kerrisk - New link to strerror.3 - Fix missing link - Global changes -------------- -Various pages - Michael Kerrisk - Update FTM requirements (_DEFAULT_SOURCE) - Michael Kerrisk - Update feature test macro requirements - Update to use _DEFAULT_SOURCE, and also changes brought by - glibc commit 266865c0e7b79d4196e2cc393693463f03c90bd8. - -Various pages - Michael Kerrisk - Simplify FTM requirements - Looking at <features.h> (or feature_test_macros(7)), one can - see that when _XOPEN_SOURCE is defined with the value 700 - (or greater), then _POSIX_C_SOURCE is defined with the value - 200809L (or greater). Therefore, terms in the man pages such as - - _XOPEN_SOURCE\ >=\ 700 || _POSIX_C_SOURCE\ >=\ 200809L - - can be simplified to: - - _POSIX_C_SOURCE\ >=\ 200809L - -Various pages - Michael Kerrisk - Simplify FTM requirements - Looking at <features.h> (or feature_test_macros(7)), one can - see that when _XOPEN_SOURCE is defined with the value 600 - (or greater), then _POSIX_C_SOURCE is defined with the value - 200112L (or greater). Therefore, terms in the man pages such as - - _XOPEN_SOURCE\ >=\ 600 || _POSIX_C_SOURCE\ >=\ 200112L - - can be simplified to: - - _POSIX_C_SOURCE\ >=\ 200112L - -Various pages - Michael Kerrisk - Simplify FTM requirements - _XOPEN_SOURCE implies _POSIX_C_SOURCE >=2, so simplify FTM - requirements in various pages. - -Various pages - Michael Kerrisk - Remove "or 'cc -std=c99'" from SYNOPSIS - Under the FTM requirements all of these pages document the - requirement for _ISOC99_SOURCE. And feature_test_macros(7) now - documents that "cc -std=c99" produces the same effect as defining - _ISOC99_SOURCE. So, all of these pages don't additionally need - to specify "or 'cc -std=c99'" under the FTM requirements - in the SYNOPSIS. Removing that redundant text also simplifies - the SYNOPSIS a little. - -Various pages - Michael Kerrisk - Simplify FTM requirements - Looking at <features.h> (or feature_test_macros(7)), one can - see that when _XOPEN_SOURCE is defined with the value 600 - (or greater), then _POSIX_C_SOURCE is defined with the value - 200112L (or greater). Therefore, terms in the man pages such as - - _XOPEN_SOURCE\ >=\ 600 || _POSIX_C_SOURCE\ >=\ 200112L - - can be simplified to: - - _POSIX_C_SOURCE\ >=\ 200112L - -Various pages - Michael Kerrisk - Remove references to _XOPEN_SOURCE_EXTENDED in SYNOPSIS - _XOPEN_SOURCE_EXTENDED is obsolete (it existed in SUSv1, but not - subsequent standards). _XOPEN_SOURCE >= 500 produces the same - effects as (_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED). Modifying - the SYNOPSIS of various ages that contain: - - _XOPEN_SOURCE\ >=\ 500 || - _XOPEN_SOURCE\ &&\ _XOPEN_SOURCE_EXTENDED - - to just: - - _XOPEN_SOURCE\ >=\ 500 - - This has the following benefits: - - a) Simplifying the SYNOPSIS by removing ancient - historical information. - - b) Preventing users from being misled into using - _XOPEN_SOURCE_EXTENDED in new source code. - -Various pages - Michael Kerrisk - Remove mention of the obsolete _POSIX_SOURCE macro from SYNOPSIS - _POSIX_SOURCE was a POSIX.1-1990 creation that was soon made - obsolete bu _POSIX_C_SOURCE. Retaining mention of it - in the feature test macro requirements section of the - SYNOPSIS doesn't contain important information, and may - mislead readers into actually trying to use this macro. - A few mentions of it are maintained in a some pages where - defining _POSIX_SOURCE inhibits some behavior. - -Various sockets-related pages - Michael Kerrisk [Carlos O'Donell] - Use consistent argument/variable names for socket addresses and lengths - As noted by Carlos, there's quite a bit of inconsistency across - pages. Use 'addr' and 'addrlen' consistently in variables and - function arguments. - -Various pages - Michael Kerrisk - Wording fix: "current file offset" ==> "file offset" - "File offset" is the preferred POSIX terminology. - -Various pages - Michael Kerrisk - Word "descriptor" more precisely - Use either "file descriptor" or message queue descriptor". - -Various pages - Michael Kerrisk - ERRORS: add reference to signal(7) in description of EINTR - Changes to individual pages --------------------------- -locale.1 - Marko Myllynen - Add "locale -c charmap" as an example - Addresses https://bugzilla.kernel.org/show_bug.cgi?id=104511. - -localedef.1 - Marko Myllynen - Add hint on purpose of --no-archive - Indicate why using --no-archive might be a good idea. The issue - is that if you create a custom locale with localedef(1) and put - it to the locale archive then during the next glibc upgrade the - locale archive is updated as well and your custom locale is gone.) - -accept.2 - Michael Kerrisk - ERRORS: improve description for EBADF - -adjtimex.2 - Michael Kerrisk [John Stultz] - Various improvements after feedback from John Stultz - Michael Kerrisk - Remove FTM requirements - It seems that adjtimex() never needed _BSD_SOURCE (and my - earlier commit 5918743bc8b02b was simply a blunder). - Michael Kerrisk - Split EINVAL error cases - Michael Kerrisk - Note treatment of out-of-range buf.offset - Michael Kerrisk - Don't refer reader to adjtime(3) - Probably, it's not wise to suggest adjtime(3) as the more - portable API. Rather, ntp_adjtime(3) should be used. - Michael Kerrisk [Naresh Kamboju] - Update details of buf.offset EINVAL error - Michael Kerrisk - SEE ALSO: add ntp_gettime(3) - Michael Kerrisk - Improve description of some PPS timex fields - Michael Kerrisk - Add ATTRIBUTES section - William Preston [Petr Gajdos] - Update a detail in adjtimex return value description - Michael Kerrisk - Note range constraints and clamping for ADJ_FREQUENCY - -bdflush.2 - Michael Kerrisk - Note that glibc support for this system call went away in version 2.23 - -bind.2 - Michael Kerrisk - Improve description of ENOENT error - -bpf.2 - Michael Kerrisk - Document close-on-exec semantics - The close-on-exec file descriptor flag is automatically enabled - for FDs returned by bpf(). - -chmod.2 - Michael Kerrisk - Clarify terminology (file mode versus file permission bits) - -chown.2 - Michael Kerrisk - ERRORS: improve EBADF description - -clone.2 -unshare.2 - Michael Kerrisk - Remove mention of _BSD_SOURCE and _SVID_SOURCE - The right way to expose declarations for these Linux-specific - system calls was always _GNU_SOURCE. Mentioning the historical - use of _BSD_SOURCE and _SVID_SOURCE just clouds the issue. - -connect.2 - Michael Kerrisk - ERRORS: improve EBADF description - -create_module.2 - Michael Kerrisk - Glibc 2.23 removed last vestiges of support for this system call - -delete_module.2 - Michael Kerrisk - Glibc 2.23 removed last vestiges of support for this system call - -epoll_ctl.2 - Michael Kerrisk - Document ELOOP error for circular monitoring loops - -eventfd.2 - Michael Kerrisk - Note that eventfd info is available in /proc/PID/fdinfo - -execve.2 - Michael Kerrisk [Krzysztof Adamski] - Add EPERM error for capabilities check of capability-dumb binaries - Michael Kerrisk - Add reference to ld-linux.so(8) - Michael Kerrisk - SEE ALSO: add system(3) - -fanotify_init.2 - Michael Kerrisk - Note kernel version that allowed O_CLOEXEC for event_f_flags - -fcntl.2 -flock.2 - Michael Kerrisk - SEE ALSO: add lslocks(8) - -fcntl.2 - Michael Kerrisk [Jason Vas Dias] - Rework description of F_SETOWN - As suggested by Jason, make it clearer that I/O signalling - requires the use of both F_SETOWN and O_ASYNC. While we're at, - make a few other cleanups to the text. - Michael Kerrisk - Remove mention of _BSD_SOURCE to get definition of F_SETOWN/F_GETOWN - This usage went away in glibc 2.20, and the simplest remedy - is just to omit mention of it. - -futex.2 - Michael Kerrisk - FUTEX_CLOCK_REALTIME can now be used with FUTEX_WAIT - -get_kernel_syms.2 - Michael Kerrisk - Note that glibc des not support this system call - -init_module.2 - Michael Kerrisk - Glibc 2.23 removed last vestiges of support for this system call - -ioctl_list.2 - Heinrich Schuchardt - Include uapi/linux/wireless.h - Add the list of wireless IOCTLs. - Heinrich Schuchardt - Path to sockios.h - sockios.h is now in include/uapi - Heinrich Schuchardt - Add reference to netdevice.7 - netdevice.7 describes most of the IOCTLs of sockios.h - Heinrich Schuchardt - Transfer structure (wireless.h IOCTLs) - The sole parameter to be passed to the wireless.h IOCTLs is - of type struct iwreq *. - -ioperm.2 - Michael Kerrisk [Alex Henrie] - ioperm.2: Permissions are inherited across fork(2) - See https://bugzilla.kernel.org/show_bug.cgi?id=99911 - -iopl.2 - Michael Kerrisk [Alex Henrie] - Permissions are not inherited across fork(2) or preserved on execve(2) - See https://bugzilla.kernel.org/show_bug.cgi?id=99901 - -lseek.2 - Michael Kerrisk - FUSE now supports SEEK_HOLE and SEEK_DATA - Michael Kerrisk - NFS supports SEEK_HOLE and SEEK_DATA - - Michael Kerrisk - SEE ALSO: add open(2) - -madvise.2 - Michael Kerrisk - Clarify MADV_HWPOISON wording to say that it applies to a page range - -mknod.2 - Michael Kerrisk - SEE ALSO: add mknod(1) - -mount.2 - Michael Kerrisk - SEE ALSO: add findmnt(8) - -open.2 - Michael Kerrisk - NOTES: mention existence of proc/PID/fd and /proc/PID/fdinfo - Mark Post [Petr Gajdos] - O_TMPFILE support is now provided bt Btrfs - -pipe.2 - Michael Kerrisk [Eric Blake] - Note treatment of 'pipefd' on error - -poll.2 - Michael Kerrisk [Josh Triplett] - Document spurious EAGAIN error that can occur on other systems - Light reworking of text proposed by Josh Triplett. - -readlink.2 - Michael Kerrisk - Clarify EINVAL error description - -recv.2 - Heinrich Schuchardt - Equivalence to read() - Describe the recv(2)-read(2) and the recvfrom(2)-recv(2) - equivalences for zero-valued arguments. - Michael Kerrisk - MSG_WAITALL has no effect for datagram sockets - -recv.2 -cmsg.3 - Nikola Forró - Fix type of cmsg_len member of cmsghdr structure - The type shown for cmsg_len member of cmsghdr structure is socklen_t, - but the actual type used by glibc and the kernel is size_t. - The information was obtained from glibc source code: - http://bit.ly/21m1RMp - Michael Kerrisk - Note that cmsg_len is typed as socklen_t in POSIX.1 - - -sched_setaffinity.2 - Michael Kerrisk [Florian Weimer, Florian Weimer] - Warn that CPU_ALLOC() may allocate a slightly CPU set than requested - Michael Kerrisk [Florian Weimer] - Add reference to CPU_ALLOC(3) - -sched_setattr.2 - Michael Kerrisk [Akihiro Suda] - EPERM depends on affinity mask of target thread, not calling thread - -select.2 - Michael Kerrisk [Josh Triplett] - Document spurious EAGAIN error that can occur on other systems - Light reworking of text proposed by Josh Triplett. - Nikos Mavrogiannopoulos - Mention the 'fd_set' size limitation early and refer to poll(2) - Change this because of the serious limitation of select() - imposing a limit on the range of file descriptors that can - be monitored. This is currently mentioned too late in the - documentation (in the NOTES section). The man page should - warn early and refer to poll(2) as soon as possible. - Michael Kerrisk - Add details on the glibc fixed-size fd_set limitation - No modern application should use select() on Linux. - -select_tut.2 - Michael Kerrisk - Some readability fixes to example program - Michael Kerrisk - Better variable names in example program - Michael Kerrisk - Simplify 'if' logic in in example program - Michael Kerrisk - Use correct type (socklen_t) for addrlen - -semctl.2 - Michael Kerrisk [Davidlohr Bueso, Manfred Spraul, Philip Semanchuk] - NOTES: note when 'sempid' is set on various implementations - See https://bugzilla.kernel.org/show_bug.cgi?id=112271 and - http://thread.gmane.org/gmane.linux.kernel/2162754/ - Subject: [PATCH] Don't set sempid in semctl syscall. - Date: 2016-02-26 12:21:38 GMT - -semop.2 - Michael Kerrisk - Tweak comment describing 'sempid' - -sendfile.2 - Askar Safin - Fix incorrect description in text referring to splice(2) - Michael Kerrisk - SEE ALSO: add copy_file_range(2) - -setpgid.2 - Michael Kerrisk - Correct/simplify FTM requirements for BSD setpgrp() and getpgrp() - -signalfd.2 - Michael Kerrisk - Note that signalfd info is available in /proc/PID/fdinfo - -sigprocmask.2 - Michael Kerrisk [Mike Frysinger] - Explicitly refer the reader to sigsetops(3) - This man page did not make it obvious which functions - should be used for manipulating signals sets, nor where - those functions were documented. - -socketpair.2 - Michael Kerrisk [Eric Blake] - Note treatment of 'sv' on error - -splice.2 - Askar Safin - Improve description of 0 return value. - See https://bugzilla.kernel.org/show_bug.cgi?id=90911 - -statfs.2 - Michael Kerrisk [Jakub Wilk] - Use consistent case for hex constants - -sync.2 - Christoph Hellwig - Clarify description and document the Linux data integrity guarantees - -syscall.2 - Mike Frysinger - Add more architectures and improve error documentation - Move the error register documentation into the main table rather - than listing them in sentences after the fact. - - Add sparc error return details. - - Add details for alpha/arc/m68k/microblaze/nios2/powerpc/superh/ - tile/xtensa. - -syscalls.2 - Michael Kerrisk - Add copy_file_range(2) - -times.2 - Kondo, Naoya - Fix an incorrect description in NOTES - The text has an incorrect description in NOTES, it says - that (2^32/HZ) - 300 is about 429 million.
