+New and rewritten pages
+-----------------------
+
+
Newly documented interfaces in existing pages
---------------------------------------------
-tsearch.3
- Florian Weimer [Michael Kerrisk]
- Document the twalk_r() function added in glibc 2.30
-
New and changed links
---------------------
-twalk_r.3
- Michael Kerrisk
- New link to twalk(3) page
+
+Global changes
+--------------
Changes to individual pages
---------------------------
-accept.2
- Michael Kerrisk
- Note that 'addrlen' is left unchanged in the event of an error
- See http://austingroupbugs.net/view.php?id=836.
-
-bpf.2
- Michael Kerrisk
- Update kernel version info for JIT compiler
-
-clone.2
- Michael Kerrisk [Jakub Nowak]
- CLONE_CHILD_SETTID has effect before clone() returns *in the child*
- CLONE_CHILD_SETTID may not have had effect by the time clone()
- returns in the parent, which could be relevant if the
- CLONE_VM flag is employed. The relevant kernel code is in
- schedule_tail(), which is called in ret_from_fork()
- in the child.
-
- See https://bugzilla.kernel.org/show_bug.cgi?id=203105
-
-execve.2
-exec.3
- Michael Kerrisk [Dr. Jürgen Sauermann]
- Consistently use the term 'pathname' (not 'path')
-
-execve.2
- Michael Kerrisk
- Note that stack+environ size is also limited to 3/4 of _STK_LIM
- In fs/exec.c::prepare_arg_pages(), we have:
-
- limit = _STK_LIM / 4 * 3;
- limit = min(limit, bprm->rlim_stack.rlim_cur / 4);
- Michael Kerrisk [Dr. Jürgen Sauermann]
- SEE ALSO: refer to exec(3) (rather than execl(3))
-
-pipe.2
- Michael Kerrisk
- Note that 'pipefd' is left unchanged in the event of an error
- See http://austingroupbugs.net/view.php?id=467.
-
-sched_setaffinity.2
- Michael Kerrisk [Brice Goglin]
- Correct details of return value of sched_getaffinity() syscall
- Things changed a little with:
-
- commit cd3d8031eb4311e516329aee03c79a08333141f1
- Author: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>
- Date: Fri Mar 12 16:15:36 2010 +0900
-
-setfsgid.2
- Michael Kerrisk
- Rewrite for improved clarity and defer to setfsuid() for details
- Rewrite for improved clarity and defer to setfsuid(2) for the
- rationale of the fsGID rather than repeating the same details
- in this page.
-
-setfsuid.2
- Michael Kerrisk
- Rewrite for improved clarity and to hint history more explicitly
- The current text reads somewhat clumsily. Rewrite it to introduce
- the eUID and fsUID in parallel, and more clearly hint at the the
- historical rationale for the fsUID, which is detailed lower in
- the page.
-
-socketpair.2
- Michael Kerrisk
- Clarify that 'sv' is left unchanged in the event of an error
- See also http://austingroupbugs.net/view.php?id=483.
-
-splice.2
- Slavomir Kaslev
- EAGAIN can occur when called on nonblocking file descriptors
-
-syscalls.2
- Michael Kerrisk [Andreas Korb]
- Remove crufty text about i386 syscall dispatch table
- The removed text long ago ceased to be accurate. Nowadays, the
- dispatch table is autogenerated when building the kernel (via
- the kernel makefile, arch/x86/entry/syscalls/Makefile).
-
-tee.2
- Slavomir Kaslev
- EAGAIN can occur when called on nonblocking file descriptors
-
-fopen.3
- Elliot Hughes
- Explain BSD vs glibc "a+" difference
- Where is the initial read position for an "a+" stream?
-
- POSIX leaves this unspecified. Most BSD man pages are silent, and
- MacOS has the ambiguous "The stream is positioned at the end of
- the file", not differentiating between reads and writes other than
- to say that fseek(3) does not affect writes. glibc's documentation
- explicitly specifies that the initial read position is the
- beginning of the file.
-
- My new wording is based on the BSD implementations, so you may
- prefer to replace the non-glibc section with "unspecified", or
- indeed remove all claims about the initial read position.
-
-mallinfo.3
- Elliott Hughes
- Further discourage use of mallinfo()
- The BUGS section already explains why you need to be cautious
- about using mallinfo, but given the number of bug reports we see
- on Android, it seems not many people are reading that far. Call it
- out up front.
-
-malloc_trim.3
- Carlos O'Donell
- Update trimming information
- Since glibc 2.8, commit 68631c8eb92, the malloc_trim function has
- iterated over all arenas and free'd back to the OS all page runs
- that were free. This allows an application to call malloc_trim to
- consolidate fragmented chunks and free back any pages it can to
- potentially reduce RSS usage.
-
-posix_memalign.3
- Elliot Hughes
- Some functions set errno
- True of bionic, glibc, and musl. (I didn't check elsewhere.)
-
-resolver.3
- Michael Kerrisk [Wladimir Mutel]
- Mention that some functions set 'h_errno'
-
-stdarg.3
- Michael Kerrisk [Vincent Lefevre]
- Remove the NOTES section describing the ancient varargs macros
- stdarg.h is now 30 years old, and gcc long ago (2004) ceased to
- implement <varargs.h>. There seems little value in keeping this
- text.
-
- See https://bugzilla.kernel.org/show_bug.cgi?id=202907
- Michael Kerrisk [Egmont Koblinger]
- Add a note that "..." in function signature means a variadic function
- Egmont suggested adding this, because the string "..." appears
- at several other points in the page, but just to indicate that
- some text is omitted from example code.
-
-strerror.3
- Jakub Wilk
- Don't discuss buffer size for strerror_l()
- Unlike strerror_r(), strerror_l() doesn't take buffer length as an
- argument.
-
-strtol.3
-strtoul.3
- Jakub Wilk
- SEE ALSO: add strtoimax(3), strtoumax(3)
-
-sysconf.3
- Michael Kerrisk [Hugues Evrard]
- Clearly note that _SC_PAGESIZE and _SC_PAGE_SIZE are synonyms
-
-tsearch.3
- Florian Weimer
- Do not use const arguments in twalk() callback
- The const specifier is not part of the prototype (it only applies
- to the implementation), so showing it here confuses the reader.
- Michael Kerrisk
- SYNOPSIS: add missing definition of 'VISIT' type
- Michael Kerrisk
- Reformat twalk() and twalk_r() prototypes for easier readability
-
-console_codes.4
- Jakub Wilk
- Document that \e[1;n] and \e[2;n] support 16 colors
- Source: setterm_command() in drivers/tty/vt/vt.c
-
-elf.5
- Michael Kerrisk [Keegan Saunders]
- A data segment does not have PF_X
-
-proc.5
- Michael Witten [Anisse Astier]
- Add missing Inode field to /proc/net/unix
-
-hostname.7
- Florian Weimer
- HOSTALIASES/search path processing is DNS-specific
- Other NSS modules do not necessarily honor these settings.
-
-inode.7
- Michael Kerrisk
- Note that timestamp fields measure time starting at the Epoch
- Michael Kerrisk
- Timestamp fields are structures that include a nanosecond component
- Michael Kerrisk
- Add references to execve(2) to describe set-UID/set-GID behaviors
