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

- /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:

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

-
-bind.2
- Michael Kerrisk
- Improve description of ENOENT error
-
-bpf.2
- Michael Kerrisk

- 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

- 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

- 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 *.
-

- 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]

-
-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.

- 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. It is correct
- only if HZ=10 which does not look common today. So just
- removing "(i.e., about 429 million)" is good enough.
-
-truncate.2
- Michael Kerrisk
- SEE ALSO: add truncate(1)
-
-uselib.2
- Michael Kerrisk
- Mention CONFIG_USELIB
- Michael Kerrisk
- Note that glibc does not support this (obsolete) system call
-
-wait.2
-wait4.2
- Michael Kerrisk
- Rename the "status" argument to "wstatus"
- The fact that exit(3)/_exit(2) has an argument called
- "status" and the same name is used in the arguments to the
- wait*() calls can a little too easily lead the user into
- thinking that the two arguments hold the same information,
- when of course they don't. So, use a different name
- for the argument of the wait*() functions, to reduce
- the chances of such confusion.

-
-setjmp.3
- Michael Kerrisk
- Rewrite and merge longjmp()/siglongjmp() discussion into this page

- we're at it, rework almost the entire text and add several
- more details.
- Michael Kerrisk
- Note the interactions of longjmp() and non-async-signal-safe functions
- POSIX.1-2008 TC2 adds explicit text on this point.

-timegm.3
- Michael Kerrisk [Stephen Hurd, Mats Wichmann]
- Remove sample implementation of timegm()
- Stephen and Mats both question the wisdom of showing a portable
- *non-thread-safe* implementation of timegm(), and I find it
- hard to disagree. So, remove this code.
