The wording describing how errno is set was fixed up in these pages.
Typographical or grammatical errors have been corrected in several
other places.
Changes to individual pages

Adjusted descriptions of argument file types to be closer to
2.6 reality.
Wording and formatting changes.
ctan.3
ctanh.3

Formulae on the pages should be T = S / C not T = C / S.

New link to ptsname.3.
shm_open.3
Matthew Gregan
add <fcntl.h> to synopsis
as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=271243

+BSD 4.4, SUSv3
as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=234443
strfry.3
Joshua Kwan

strftime.3
Cartsen Hey
as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=276248
Changed range for "%S" from 0..61 to 0..60.
SUSv3 says 0..60. I think the manual page probably says
0..61, because that's what SUSv2 said.
(Some other implementations' man pages also say 0..61 --
e.g., Solaris 8 & 9, Tru64 5.1B; FreeBSD 5.1 says 0..60.)
The glibc manual currently says 0..60.
Given that SUSv3 says 0..60, I've changed the
manual page to also say this:
-The second as a decimal number (range 00 to 61).
+The second as a decimal number (range 00 to 60).
+(The range is up to 60 to allow for occasional leap seconds.)
sysconf.3

+.BR POSIX2_FORT_DEV " - " _SC_2_FORT_DEV

Pedro Zorzenon
as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=242638
Noted use of _XOPEN_SOURCE to get macros from <stdlib.h>
for wait(2).
mtk
Changed name of argument from 'string' to 'command' (like POSIX).
Noted that glibc does nowadays explicitly check for the existence
of the shell if 'command' is NULL, rather than the older behavior
of assuming the shell exists and always returning 1 if
'command' is NULL.
Other wording and formatting clean-ups.
undocumented.3
Remove some functions names that *are* documented.

Improved DESCRIPTION; clarified distinction between
EACCES and ENOEXEC.
bcopy.3

==================== Changes in man-pages-2.10 ====================
Released: 2005-10-19
Global changes
--------------
The changes in this release consist *solely* of formatting fixes, with
the aim bringing greater consistency to the manual pages according to
the following rules:
-- Function name references should *always* be followed by
parentheses, "()" (possibly containing a manual page section
number).
-- The parentheses following a function name should *not* be
formatted. Thus, for example, instead of:
.B name()
one should write:
.BR name ()
Much of the change was automated using two scripts:
add_parens_for_own_funcs.sh and unformat_parens.sh.
For the (possible) benefit of downstream manual page maintainers and
translators, I have placed these scripts in a new subdirectory 'scripts'.
NOTE THE FOLLOWING POINTS WELL:
-- These scripts provide a computer-assisted solution to the above
two goals. However, they are not perfect, and their output should
be scanned by a human. (To see what changes the two scripts
*would* make, without making them, use the "-n" command line option.)
-- The scripts do not fix all instances that violate the above rules:
some manual fixes are required. Two further scripts are provided
to help find remaining instances of function names without
following "()": find_dots_no_parens.sh and find_slashes_no_parens.sh.
The following changes were made:
-- add_parens_for_own_funcs.sh was applied to the pages in Sections
2 and 3.
-- unformat_parens.sh was applied to pages in Sections 2, 3, 4, and 7
(the only sections where such changes were required).
-- further changes (not so very many) were performed by hand.
(found places to fix with the assistance of find_dots_no_parens.sh
and find_slashes_no_parens.sh).

Most pages
mtk
There was a major reworking of the CONFORMING TO sections
in most manual pages.
* generally try to rationalize the names used for standards.
The preferred names are now documented as the head words
of the list in standards(7). For the future: there is
probably no need to talk about anything more than
C89, C99, POSIX.1-2001 (or later), xBSD, and SVr4.
(In particular, I've eliminated most references to XPG
and SVID, replacing them with references to SUS or SVr4.)
* eliminate discussion of errors that can occur on other
systems. This information exists only patchily in the
manual pages, is probably of limited use, is hard to maintain,
and was in some cases simply wrong (and probably always was).
* Tried to ensure that those interfaces specified in C99 or
POSIX.1-2001 are marked as such in their manual pages.

Evan Teran / mtk
Add text describing behavior of the Linux brk() system call
and point out that the glibc brk() wrapper provides different
behavior.

rtc.4
David Brownell
Update the RTC man page to reflect the new RTC class framework:
- Generalize ... it's not just for PC/AT style RTCs, and there
may be more than one RTC per system.
- Not all RTCs expose the same feature set as PC/AT ones; most
of these ioctls will be rejected by some RTCs.
- Be explicit about when {A,P}IE_{ON,OFF} calls are needed.
- Describe the parameter to the get/set epoch request; correct
the description of the get/set frequency parameter.
- Document RTC_WKALM_{RD,SET}, which don't need AIE_{ON,OFF} and
which support longer alarm periods.
- Hey, not all system clock implementations count timer irqs any
more now that the new RT-derived clock support is merging.
proc.5

Jorge Peixoto de Morais Neto / mtk
Improve ENOENT description.
clone.2
mtk
Added some detail to the prototype.
Added some notes on IA-64's clone2().
epoll_ctl.2

Add text to note that EPOLLRDHUP appeared in kernel 2.6.17.
faccessat.2
Justin Pryzby
Various fixes as per
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=411177

Added a few words to note that RLIMIT_NPROC is really a limit on
threads.
io_cancel.2
io_destroy.2
io_getevents.2
io_setup.2
io_submit.2
Fedora downstream patches; thanks to Ivana Varekova
s%linux/aio.h%libaio.h% in SYNOPSIS.

mbind.2
Samuel Thibault / mtk
Fix EINVAL description.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=411777
mincore.2
Nick Piggin
Kernel 2.6.21 fixes several earlier bugs in mincore().
Nick Pollitt
Remove words "of a file" -- mincore() is describing
memory residence information, not properties of a file.
mtk
Rewrote various parts to make the page clearer.
mmap.2
mtk
Rewrote and reorganized various parts to be clearer.
Taken from Fedora downstream patches; thanks to Ivana Varekova
Removed text stating that mmap() never returns 0; that's
not true.
mount.2
mtk / Val Henson
Document MS_RELATIME, new in Linux 2.6.20.
open.2
Andre Majorel / mtk
On Linux, the error returned when opening a large file on a
32-bit system is actually EFBIG, not EOVERFLOW.
posix_fadvise.2
Pádraig Brady
Fix RETURN VALUE description: returns error number of failure.
rename.2
mtk / Timo Sirainen
Various improvements to DESCRIPTION.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=416012
semop.2
mtk
If sops contains multiple operations, then these are performed
in array order. All Unix systems that I know of do this,
and some Linux applications depend on this behavior. SUSv3
made no explicit statement here, but SUSv4 will explicitly
require this behavior.
Small rewording of explanation of "atomically".
signal.2
Nicolas François
Fix incorrect argument name in DESCRIPTION.
mtk
Small wording improvement.

Fix inconsistent argument names in SYNOPSIS and DESCRIPTION.
statvfs.2
mtk
Small wording clarification.
symlink.2

"open(2) and NFS". There is no relevant text in open.2 as
far as I (mtk) can see.
time.2
mtk / Reuben Thomas
Remove sentence "gettimeofday() obsoleting time() on 4.3BSD".
This information is old, and probably no longer relevant.

write.2
mtk, after an idea from a downstream Fedora patch.
Clarified discussion of /count == 0/ case.
ptrace.2
Chuck Ebbert
When the parent receives an event with PTRACE_EVENT_* set,
the child is not in the normal signal delivery path. This
means the parent cannot do ptrace(PTRACE_CONT) with a signal
or ptrace(PTRACE_KILL). kill() with a SIGKILL signal can be
used instead to kill the child process after receiving one
of these messages.
sched_setaffinity.2
mtk
Fix glibc version number in description of 'cpusetsize' argument.
vfork.2
mtk
Stripped some excess/outdated text from the BUGS section.

Taken from Fedora downstream patches; thanks to Ivana Varekova
+ Carlo Marcelo Arenas Belon
Add "#include <stdlib.h>" to example program.
fclose.3
mtk
Complete rewrite. The existing page was hard to read,
and the RETURN VALUE description seems to be wrong.
getopt.3
mtk
Added getopt() example program.
mtk
Add a few words to clarify the operation of the GNU-specific
double-colon feature, which allows options to have optional
arguments.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=352139
glob.3
Nicolas François
Fix PROTOTYPE.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400971
Needs _XOPEN_SOURCE == 600; as per
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400975

mtk, after a suggestion by Justin Pryzby
Added some text warning that the "__" macros that
<features.h> defines internally should never be
directly defined by programs.
mtk, based on notes by Jakub Jelinek
Document _FORTIFY_SOURCE
(See http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02055.html )
mtk
Document _REENTRANT and _THREAD_SAFE.
mdoc.7

to get this changed, but maybe that won't be done because it
is an ABI change.
mtk
Added an example program.

Removed pages (!)
-----------------
Most Section 1 man pages are removed
mtk (with help from Mike Frysinger, Laird Shaw, Andreas Halter)
Once upon time Andries added a number of Section 1 manual pages
to man-pages. However, since that time, those pages have not
seen much maintenance, and are not in fact distributed in most
distributions. Instead most distributions supply the
coreutils versions of these pages, which are currently
maintained. In addition, man-pages provides the 1p pages,
which document the portable subset of functionality of these
commands. Since the man1 pages are mostly unneeded, and
out of date, I'm removing them. The following pages disappear:
chgrp.1
chmod.1
chown.1
cp.1
dd.1
df.1
diff.1
dir.1
dircolors.1
du.1
install.1
ln.1
ls.1
mkdir.1
mkfifo.1
mknod.1
mv.1
rm.1
rmdir.1
touch.1
vdir.1
The following Section 1 pages will be kept:
intro.1
ldd.1
time.1
==================== Changes in man-pages-2.51 ====================
Released: 2007-05-28

(Hopefully) all cross references outside a page now include a
section number. This should permit better resulting output
from a man2html-type conversion.
Various pages

".BR name ()".
Changes to individual pages

little statesmen and philosophers and divines"

Global changes
--------------
Most of the changes below are about bringing greater consistency
to manual pages, including reducing the wide range of .SH
Section headings.
Typographical or grammatical errors have been corrected in several
places.
Various pages
mtk
Make 'manual' component of .TH line into the string
"Linux Programmer's Manual".
Reason: consistency.
Various pages
mtk
Changed date in .TH line into form YYYY-DD-MM.
Reason: consistency.
Various pages
mtk
Some .SH header lines were made into .SS lines. (One of the aims
here is to reduce the number of non-standard .SH lines.)
Various pages
mtk
Change title .SH sections named "NOTE" to "NOTES", in some cases
also changing the location of the section within the page.
Reason: consistency.
Various pages
mtk
Commented out .SH AUTHOR sections; the right place for
documentation authorship sections is usually comments at the
top of the page source.
Various pages
mtk
Changed .SH HISTORY to .SH VERSIONS.
Reason: in many cases, HISTORY was being used to describe
Linux/glibc version information, as was already done for
VERSIONS sections in other pages.
Various pages
mtk
Removed HISTORY section, or moved it as a subsection or paragraphs
under another section e.g., NOTES.
Reason: there are too many arbitrary section (.SH) names, and
a HISTORY section never was consistently used across Linux
manual pages.
Various pages
mtk
Moved SEE ALSO section to be last section on the page
Reason: consistency -- and this is where SEE ALSO should be!
Various pages
mtk
Relocated GLIBC NOTES as subsection under NOTES
Reason: reduce number of arbitrary section (.SH) names.

mtk
Remove section about effect of fork()/exec()/exit(); shmop.2
contains the same text, and it only needs to be said once.
shmop.2
mtk
Minor rewording under DESCRIPTION.
daemon.3
mtk
Minor wording and formatting changes.
encrypt.3
mtk
Removed statement that glibc unconditionally exposes declarations
of encrypt() and setkey(), since portable applications must
use <unistd.h> and define _XOPEN_SOURCE to obtain the declarations
of setkey() and encrypt(). Adjusted example program accordingly.
mkstemp.3
mtk
Slight rewording.
LDP.7
mtk
Minor wording and formatting changes.
man.7
mtk
Substantial rewrite, revising and extending the discussion
about desired conventions for writing pages.
There will be further updates to this page in the next few
man-pages releases.
==================== Changes in man-pages-2.53 ====================
Released: 2007-05-30
"A foolish consistency is the hobgoblin of little minds, adored by
little statesmen and philosophers and divines"
Ralph Waldo Emerson (1803-1882)
"But damn it, these man pages are a mess!"
Global changes
--------------
Many many pages
mtk
Reordered sections to be more consistent, in some cases renaming
sections or shifting paragraphs between sections.
man7/*
mtk
In various pages in this section, .SH headings were
converted to .SS.
==================== Changes in man-pages-2.54 ====================
Released: 2007-06-07

The following people contributed notes, ideas, or patches that have
been incorporated in changes in this release:
Emmanuel Mogenet <emogenet@google.com>
Michael Berg <michaeljberg@gmail.com>
Apologies if I missed anyone!
Global changes
--------------
Various pages
mtk
Where there is an instruction in the SYNOPSIS about linking
or compiling with a certain option, the option is now
marked up in italics (e.g., "\fI-lm\fP").
Various pages
mtk
Added page numbers to page cross references.
A few pages
mtk
s/manpage/man page/, for consistency.
Typographical or grammatical errors have been corrected in several
places.
New pages
---------
man-pages.7
mtk
A description of the conventions that should be followed
when writing pages for the man-pages package.
Removed pages
-------------
man1/README
mtk
Already deleted most of the man1 pages previously, so
this doesn't need to stay.
LDP.7
mtk
Removed this page since it is out of date, and the proper place
to go for up-to-date information is http://www.tldp.org/
ksoftirq.9
mtk
Reason: this was the only Section 9 page, and it is old
(Linux 2.4). The man9 section never took off as an idea, and
I see little point in keeping a Section 9 with just a single
old page.
Changes to individual pages
---------------------------

A much improved example program.

s/int/socklen_t/ for type of gethostbyaddr() 'len' argument,
and add a few more words in NOTES about the type used here.
login.3
mtk
Removed remark from NOTES about linking with -lutil; add
text on that point to SYNOPSIS.
openpty.3
mtk
Removed redundant remark from NOTES about linking with -lutil
since there is text on that point under SYNOPSIS.

mtk
Minor rearrangement of order of text.

s/exec()/execve(2)/ in various places.

mtk
Changed "atan(1)" to "atan(1.0)" to prevent some versions of
man2html(1) from mistaking that string as a page cross reference.
rtnetlink.7
mtk
Small restructuring to avoid 'cannot adjust line' from man(1).
ldconfig.8
mtk
Removed now very out-of-date sentence about need to link shared
libraries with -lc.

mtk
Moved EXIT STATUS section.

==================== Changes in man-pages-2.56 ====================
Released: 2007-06-11
Global changes
--------------
Many pages
mtk
Removed version numbers in .TH lines.
Reason: these were only arbitrarily updated, and so impart no
useful information. Version information goes into a
VERSIONS section nowadays, and the date in the .TH line should
be updated to reflect the date of the last (significant)
change to the page.
Typographical or grammatical errors have been corrected in several
places.

==================== Changes in man-pages-2.59 ====================
Released: 2007-06-25
Global changes
--------------
Manual pages are now standardized on American spelling. See
http://en.wikipedia.org/wiki/American_and_British_English_spelling_differences
for more information on the differences. Formerly, different pages (and
sometimes even a single page!) employed American and British spelling
conventions; best to standardize on one spelling, and American English
is the standard in Computer Science.

New pages
---------
sgetmask.2
mtk
A real man page for sgetmask(2) and ssetmask(2).
(This page replaces a previous link of the same name, which
linked to signal.2.)

mtk
Details on this page are covered in syscalls.2 and in
respective syscall man pages (stat.2, uname.2).

is maintained in the HOWTOHELP file, and probably in other
places soon.

default, so that the XSI-compliant version is supplied
by default.

Maxime Vaudequin
I noticed things to correct and to clarify in subsection
"/proc/filesystems" of proc.5:
- clarify filesystems listing: not only FS compiled
into the kernel, also FS kernel modules currently loaded
- add a reference to fs(5)
- add an explanation for FS marked with "nodev"
- s/mount(1)/mount(8)/, also corrected in section "SEE ALSO"
- clarify usage by mount: the current wording may lead to
think /proc/filesystems is always used by mount when no FS
is specified. So, usage of "may" which IMHO is more
appropriate + additional explanations
In mount(8) we can see:
If no -t option is given, or if the auto type is
specified, mount will try to guess the desired type.
If mount was compiled with the blkid library, the
guessing is done by this library. Otherwise, mount
guesses itself by probing the superblock; if that
does not turn up anything that looks familiar,
mount will try to read the file /etc/filesystems,
or, if that does not exist, /proc/filesystems.
All of the filesystem types listed there will be
tried, except for those that are labeled "nodev"
(e.g., devpts, proc and nfs). If /etc/filesystems
ends in a line with a single * only, mount will
read /proc/filesystems afterwards.
Samuel Thibault
Since linux 2.6.11, /proc/stat has an eighth value for cpu
lines: stolen time, which is the time spent in other operating
systems when running in a virtualized environment.
arp.7
Updated BUGS text referring to jiffies; refer to time.7 instead.
credentials.7
mtk
Add words to note that file system ID is Linux specific.
hier.7
Maxime Vaudequin
This is some corrections for hier.7:
- missing period for /media and /mnt
- /mnt description is not totally correct, it is true for some
distributions but in others /mnt is used as a temporary FS
mount point, as it is specified by FHS:
http://www.pathname.com/fhs/pub/fhs-2.3.html#MNTMOUNTPOINTFORATEMPORARILYMOUNT
- s/X-Windows/X-Window/ (3 occurrences)
- section "SEE ALSO": s/mount(1)/mount(8)/
man-pages.7
man.7
mdoc.7
mdoc.samples.7
mtk / Nicolas François
Nowadays tmac.XXX are called XXX.tmac.
pthreads.7
mtk

Clarify that SO_SNDTIMEO and SO_RCVTIMEO only have effect for
socket I/O calls; not for multiplexing system calls like
select() and poll().
time.7
mtk

*.1p
*.3p
mtk, after a note by Andi Kleen and consultation with Andrew Josey.
Add a PROLOG section:
This manual page is part of the POSIX Programmer's Manual.
The Linux implementation of this interface may differ
(consult the corresponding Linux manual page for details
of Linux behavior), or the interface may not be implemented
on Linux.
*.0p
*.1p
*.3p
mtk
Some formatting fixes, mostly to get rid of unwanted
spaces before "," in formatted output.
*
*/*
mtk
Change all occurrences of my email address in man-pages source
to my new gmail address.
Many many pages
Maxime Vaudequin
I noticed useless use of macros with alternating formatting
(".IR" instead ".I" which suffices, ".BR" instead ".B", etc.)
because there is only one element. For example in ldconfig.8:
-.BR /sbin/ldconfig
+.B /sbin/ldconfig
This is not very important, it only makes the sources more tidy.
To find these I used:
egrep '^\.(B[RI]|R[IB]|I[RB]) ([^ ]+|\"[^\"]\+\")$'
And if you want to make these changes, you can use:
sed 's/^\(\.[BRI]\)[BRI]\( \([^ ]\+\|\"[^\"]\+\"\)\)$/\1\2/g'

s/stdlib.h/fcntl.h/ in SYNOPSIS.
proc.5
Fernando Luis Vázquez Cao
Update /proc/[number]/cmdline description.
It used to be true that the command line arguments were
not accessible when the process had been swapped out.
In ancient kernels (circa 2.0.*) the problem was that the
kernel relied on get_phys_addr to access the user space buffer,
which stopped working as soon as the process was swapped out.
Recent kernels use get_user_pages for the same purpose and thus
they should not have that limitation.
epoll.7
Davide Libenzi / mtk
Clarify the somewhat unintuitive behavior that occurs if a file
descriptor in an epoll set is closed while other file descriptors
referring to the same underlying open file description remain
open.
See also http://thread.gmane.org/gmane.linux.kernel/596462/.
mtk
Clarify error that occurs if we add an epoll fd to its own set.
mtk

mtk, after a note by Chris Heath
Rework Q1/A1, describing what happens when adding the same
file descriptor twice to an epoll set, and when adding duplicate
file descriptors to the same epoll set.
Heikki Orsila / mtk / Davide Libenzi
Clarify Q9/A9 to discuss packet/token-oriented files.
mtk, after comments by Davide Libenzi and Chris Heath
Added Q0/A0, making explicit that the key for items in an epoll
set is [file descriptor, open file description].
mtk, after a note by Ron Burk
Change A3, to note that when events are available,
the epoll file descriptor will indicate as being readable.
mtk
Add some further explanation to Q5/A5 about why an epoll file
descriptor cannot be passed across a Unix domain socket.
posixoptions.7
mtk
Add SEE ALSO entry for standards(7).
regex.7
mtk
Add grep(1) to SEE ALSO.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=348552.
standards.7
mtk
Add SEE ALSO entry for posixoptions(7).
time.7

s/unicode.com/unicode.org/
credentials.7
mtk
NOTES: Pthreads requires that all threads share the same UIDs and

changes by any thread are carried through to all POSIX threads in
a process.
mtk

supplementary groups that a process may belong to.
Clarify that supplementary group IDs are specified in POSIX.1-2001.

For answer A2, change "not recommended" to "careful programming
may be required".

==================== Changes in man-pages-3.00 ====================
Released: 2008-06-12, Konolfingen
Contributors
------------
The following people contributed notes, ideas, or patches that have
been incorporated in changes in this release:
Andries Brouwer <Andries.Brouwer@cwi.nl>
Stuart Brady <sdbrady@ntlworld.com>
Apologies if I missed anyone!
Global changes
--------------
The POSIX.1 man pages (sections 0p, 1p, 3p) have been moved out
of this package into the separate man-pages-posix package.
This made sense because those pages are seldom changed (only formatting
fixes, etc.) so that it was unnecessary to redistribute them with each
man-pages release.
console_codes.4
random.4
dir_colors.5
proc.5
glob.7
Stuart Brady
s/`/\`/ for backquotes used in command substitution, for
proper rendering in UTF-8.
Various pages
mtk, after a note from Stuart Brady
Using /'x'/ to denote a character (string) renders poorly in
UTF-8, where the two ' characters render as closing single
quotes. On the other hand, using /`x'/ renders nicely on UTF-8,
where proper opening and closing single quotes are produced by
groff(1), but looks ugly when rendered in ASCII. Using the
sequence /\\aqx\\aq/ produces a reasonable rendering ('\\aq'
is a vertical "apostrophe quote") in both UTF-8 and ASCII.
So that change is made in a number of pages.
See also http://www.cl.cal.ac.uk/~mgk25/ucs/quotes.html.
Various pages
mtk
Replace form /`string'/ by /"string"/, since the former renders
poorly in ASCII.
termios.3
console_codes.4
tty_ioctl.4
termcap.5
charsets.7
mtk
Control character names (^X) are written boldface, without
quotes.
printf.3
scanf.3
proc.5
glob.7
regex.7
mtk
Various edits to try and bring some consistency to the use of
quotes.
Changes to individual pages
---------------------------
tty_ioctl.4
mtk
Small rewordings in description of packet mode.
locale.7
mtk
Minor formatting fixes.

Clarify discussion of return value of sbrk().
mtk
DESCRIPTION: Add some sentences giving an overview of these
interfaces.
Add note recommending use of malloc(3).
Change name of brk() argument to the simpler 'addr'.

NOTES: describe case where clock_nanosleep() can be preferable.
Some minor rewrites.
open.2
mtk, after a note from Christoph Hellwig

Document ENOSYS error, which can occur if kernel was built without
CONFIG_PRINTK.
utime.2
Nicolas François
Clarify description of 'times' array for utimes().
adjtime.3
mtk
The longstanding bug that if delta was NULL, olddelta
didn't return the outstanding clock adjustment, is now fixed
(since glibc 2.8 + kernel 2.6.26).
http://sourceware.org/bugzilla/show_bug?id=2449
http://bugzilla.kernel.org/show_bug.cgi?id=6761

recognize hexadecimal components in dotted address strings;
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482973
getmntent.3
mtk, after Stuart Cunningham pointed out the typo
Remove statement that LSB deprecates the functions
"endmntent(), setmntent() [sic] and setmntent()".
This doesn't seem to be true (I can't find mention of it
being deprecated in any of the LSB specs). Rather, LSB simply
doesn't specify these functions. (LSB 1.3 had a spec of
setmntent(), but not getmntent() or endmntent(), and noted
that having a spec of setmntent() was of little use without
also having a spec of getmntent().)

Changes to individual pages (math functions)
--------------------------------------------
Almost all of the changes in this release relate to math man pages.
Very many changes were made to the math pages, including:
* Fixed feature test macros (FTMs). Often, the FTM requirements
for the "float" and "long double" versions of a math function are
different from the requirements for the "double" version. Each math
page now shows the correct FTM requirements for all three versions
of the function(s) it describes. This may have required either
a change to the existing FTM text (if the requirements for the
"double" function were already described), or the addition of an FTM
description to a SYNOPSIS where one was not previously present
(typically because the "double" version of the function does not
require any FTMs to be defined).
* CONFORMING TO: in many cases, POSIX.1-2001 was not mentioned.
Where a function is specified in POSIX.1-2001, this is now noted.
Also, statements about what other standards a function conforms to
were generally clarified. (The wording about which functions conformed
to C99 was previously often done as an add on sentence; now it is made
part of the first sentence of the CONFORMING TO section, along with
POSIX.1-2001.)
* RETURN VALUE: in many cases, pages lacked descriptions of the return
value when the function arguments are special values such as +0, -0,
NaN (not-a-number), +infinity, -infinity, etc. This has been fixed.
I carried out tests on glibc 2.8 to ensure that all of these
functions match the RETURN VALUE descriptions (and the POSIX.1-2001
requirements).
* ERRORS: many pages lacked a clear (or indeed any) description of
how errno is set on error and what exception is raised for each error.
This has been fixed. The ERRORS sections are now generally headed up
as per the POSIX.1 way of doing things, describing Pole / Range /
Domain errors, as applicable.
I carried out tests on glibc 2.8 to ensure that all of these
functions match the ERRORS descriptions. Deviations from POSIX.1-2001
requirements have been filed as glibc bug reports, and noted in the
man pages. (The pages now describe the situation for ERRORS as at glibc
2.8; I may eventually try and extend the text with descriptions of
changes in older versions of glibc.)
NOTE: one point that has not been covered in any page is the
circumstances that generate inexact (FE_INEXACT) exceptions.
(The details for these exceptions are not specified in POSIX.1-2001,
and I haven't gone looking for the standards that describe the details.)

New and rewritten pages
-----------------------
move_pages.2
Christoph Lameter, various edits and improvements by mtk
Documentation of the move_pages() system call.
This page was formerly part of the numactl package, but really
belongs in man-pages (since it describes a kernel interface).
clock_getcpuclockid.3
mtk
New page documenting the clock_getcpuclockid() library function,
available since glibc 2.2.
udplite.7
Gerrit Renker
Document the Linux implementation of the UDP-Lite protocol,
new in Linux 2.6.20.
Newly documented interfaces in existing pages
---------------------------------------------
proc.5
Christoph Lameter, minor edits and improvements by mtk
Documentation of the /proc/PID/numa_maps file.
This material was formerly the numa_maps.5 page in the numactl
package, but really belongs in man-pages (since it describes
a kernel interface).
Global changes
--------------
nanosleep.2
inet_ntop.3
inet_pton.3
scanf.3
initrd.4
mtk
Fix mis-ordered (.SH) sections.
connect.2
socket.2
rtnetlink.3
arp.7
ddp.7
ip.7
ipv6.7
netlink.7
packet.7
raw.7
rtnetlink.7
socket.7
tcp.7
udp.7
unix.7
x25.7
mtk
s/PF_/AF_/ for socket family constants. Reasons: the AF_ and
PF_ constants have always had the same values; there never has
been a protocol family that had more than one address family,
and POSIX.1-2001 only specifies the AF_* constants.
Typographical or grammatical errors have been corrected in several
other places.
Changes to individual pages
---------------------------
execve.2
mtk
The floating-point environment is reset to the default
during an execve().
get_mempolicy.2
Lee Schermerhorn
Misc cleanup of get_mempolicy(2):
+ mention that any mode flags will be saved with mode.
I don't bother to document mode flags here because we
already have a pointer to set_mempolicy(2) for more info
on memory policy. mode flags are discussed there.
+ remove some old, obsolete [IMO] NOTES and 'roff comments.
Lee Schermerhorn
Update the get_mempolicy(2) man page to add in the description of
the MPOL_F_MEMS_ALLOWED flag, added in 2.6.23.
mtk
Document additional EINVAL error that occurs is MPOL_F_MEMS_ALLOWED
is specified with either MPOL_F_ADDR or MPOL_F_NODE.
getitimer.2
mtk
CONFORMING TO: POSIX.1-2008 marks getitimer() and setitimer()
obsolete.
mbind.2
Lee Schermerhorn
Fix error conditions, now that the kernel silently ignores
nodes outside the task's cpuset, as long as one valid node
remains.
Now that cpuset man page exists, we can refer to it. Remove
stale comment regarding lack thereof.
Lee Schermerhorn
Add brief discussion of mode flags.
Lee Schermerhorn
Attempt to clarify discussion of MPOL_DEFAULT.
mtk
Fix URI reference for libnuma.
mprotect.2
mtk / Maxin John
Remove EFAULT from errors. Under ENOMEM error, note that
EFAULT was the error produced in some cases for kernels before
2.4.19.
msgctl.2
mtk, after a note from Filippo Santovito
In the ipc_perm structure definition, some fields were
incorrectly named: s/key/__key/ and s/seq/__seq/.
set_mempolicy.2
Lee Schermerhorn
Fix up the error return for nodemask containing nodes disallowed by
the process' current cpuset. Disallowed nodes are now silently ignored,
as long as the nodemask contains at least one node that is on-line,
allowed by the process' cpuset and has memory.
Now that we have a cpuset man page, we can refer to cpusets directly
in the man page text.
Lee Schermerhorn
Another attempt to rationalize description of MPOL_DEFAULT.
Since ~2.6.25, the system default memory policy is "local allocation".
MPOL_DEFAULT itself is a request to remove any non-default policy and
"fall back" to the surrounding context. Try to say that without delving
into implementation details.
Lee Schermerhorn
Add discussion of mempolicy mode flags to set_mempolicy(2).
This adds another reason for EINVAL.
setpgid.2
mtk
CONFORMING TO: POSIX.1-2008 marks setpgrp() obsolete.
semctl.2
mtk, after a note from Filippo Santovito
In the ipc_perm structure definition, some fields were
incorrectly named: s/key/__key/ and s/seq/__seq/.
shmctl.2
Filippo Santovito / mtk
In the ipc_perm structure definition, some fields were
incorrectly named: s/key/__key/ and s/seq/__seq/.
utime.2
mtk
CONFORMING TO: POSIX.1-2008 marks utime() obsolete.
CONFORMING TO: POSIX.1-2008 removes the POSIX.1-2001 LEGACY
marking of utimes(), so mention of this point has been
removed from the page.

and getaddrinfo().
getnetent.3
mtk
Rephrase description in terms of a database, rather than a file.
Note that each of the get*() functions opens a connection to
the database if necessary.
The database connection is held open between get*() calls if
'stayopen' is non-zero (not necessarily 1).
s/zero terminated list/NULL-terminated list/
mtk
In glibc 2.2, the type of the 'net' argument for getnetbyaddr()
changed from 'long' to 'uint32_t'.

s/zero terminated list/NULL-terminated list/
mtk
RETURN VALUE: emphasize that returned pointer points to a
statically allocated structure.
SEE ALSO: add getservent_r.3.

existing material from mount.2 page.
New and changed links
---------------------
umount2.2
Michael Kerrisk

Changes to individual pages
---------------------------
execve.2
Michael Kerrisk
_SC_ARG_MAX is no longer necessarily constant
POSIX.1-2001 says that the values returned by sysconf()
are constant for the life of the process.
But the fact that, since Linux 2.6.23, ARG_MAX is settable
via RLIMIT_STACK means _SC_ARG_MAX is no longer constant,
since it can change at each execve().
Michael Kerrisk
Linux now imposes a floor on the ARG_MAX limit
Starting with Linux 2.6.23, the ARG_MAX limit became
settable via (1/4 of) RLIMIT_STACK. This broke ABI
compatibility if RLIMIT_STACK was set such that ARG_MAX
was < 32 pages. Document the fact that since 2.6.25
Linux imposes a floor on ARG_MAX, so that the old limit
of 32 pages is guaranteed.
For some background on the changes to ARG_MAX in
kernels 2.6.23 and 2.6.25, see:
http://sourceware.org/bugzilla/show_bug.cgi?id=5786
http://bugzilla.kernel.org/show_bug.cgi?id=10095
http://thread.gmane.org/gmane.linux.kernel/646709/focus=648101,
checked into 2.6.25 as
commit a64e715fc74b1a7dcc5944f848acc38b2c4d4ee2.
Also some reordering/rewording of the discussion of ARG_MAX.
fallocate.2
Michael Kerrisk
Note lack of glibc wrapper; caller must use syscall(2)
Glibc doesn't (and quite probably won't) include a
wrapper for this system call. Therefore, point out that
potential callers will need to use syscall(2), and rewrite
the RETURN VALUE text to show things as they would be if
syscall() is used.
Michael Kerrisk
Refer reader to posix_fallocate(3) for portable interface
Add a para to start of page that points out that this is the
low-level, Linux-specific API, and point the reader to
posix_fallocate(3) for the portable API.
getdents.2
readdir.3
Michael Kerrisk
d_type is currently only supported on ext[234]
As at kernel 2.6.27, only ext[234] support d_type.
On other file systems, d_type is always set to DT_UNKNOWN (0).
getdents.2
Michael Kerrisk
Add an example program
Michael Kerrisk
comment out linux_dirent fields with varying location
The location of the fields after d_name varies according to
the size of d_name. We can't properly declare them in C;
therefore, put those fields inside a comment.
Michael Kerrisk
The DT_* constants are defined in <dirent.h>
Michael Kerrisk
Remove header files from SYNOPSIS
None of the header files provides what is needed.
Calls are made via syscall(2).
Michael Kerrisk
The programmer must define the linux_dirent structure
Point out that this structure is not defined in glibc headers.
Michael Kerrisk
s/dirent/linux_dirent/
The structure isn't currently defined in glibc headers,
and the kernel name of the structure is 'linux_dirent' (as
was already used in some, but not all, places in this page).
getrlimit.2
Michael Kerrisk
Reword/relocate discussion of BSD's historical RLIMIT_OFILE
The old sentence sat on its own in an odd place, and anyway the
modern BSDs use the name RLIMIT_NOFILE.
Michael Kerrisk
Refer to execve(2) for RLIMIT_STACK's effect on ARG_MAX
Refer the reader to new text in execve(2) that describes how
(since Linux 2.6.23) RLIMIT_STACK determines the value of ARG_MAX.
getrusage.2
Michael Kerrisk
Rusage measures are preserved across execve(2)
mlock.2
Maxin John
Add EAGAIN error.
move_pages.2
Nicolas François
Make a detail of EPERM error more precise
mount.2
Michael Kerrisk
Add description of per-process namespaces
Describe per-process namespaces, including discussion
of clone() and unshare CLONE_NEWNS, and /proc/PID/mounts.
Michael Kerrisk
List a few other file systems that we may see in /proc/filesystems
Add some modern file systems to that list (xfs, jfs, ext3,
reiserfs).
Michael Kerrisk
Document MS_SILENT (and MS_VERBOSE)
mount.2
umount.2
Michael Kerrisk
Split umount*() out into a separate page
The length of this page means that it's becoming difficult
to parse which info is specific to mount() versus
umount()/umount2(), so split the umount material out into
its own page.
pause.2
Michael Kerrisk
Remove mention of words "library function"
This really is a system call.
readdir.2
Michael Kerrisk
The programmer must declare the old_linux_dirent structure
Glibc does not provide a definition of this structure.
Michael Kerrisk
s/dirent/old_linux_dirent/
Nowadays, this is the name of the structure in the
kernel sources.
Michael Kerrisk
Remove words "which may change"
These words are slightly bogus: although the interface
is obsolete, for ABI-compatibility reasons, the kernel folk
should never be changing this interface.
Michael Kerrisk
Remove header files from SYNOPSIS
glibc doesn't provide any support for readdir(2),
so remove these header files (which otherwise suggest
that glibc does provide the required pieces).
recv.2
Nicolas François
Move kernel version number to first mention to MSG_ERRQUEUE.
semop.2
Kirill A. Shutemov
Fix typo in example
(The '&' before sop in the semop() call is unneeded.)
send.2
Michael Kerrisk
Make kernel version for MSG_CONFIRM more precise
s/2.3+ only/Since Linux 2.3.15/
sigaction.2
Michael Kerrisk
Refer reader to signal(7) for an overview of signals
Explain semantics of signal disposition during fork() and execve()
Refer to signal(7) for more details on signal mask.
sigaltstack.2
Michael Kerrisk
Explain inheritance of alternate signal stack across fork(2)
sigwaitinfo.2
Michael Kerrisk
Distinguish per-thread and process-wide signals
A sentence clarifying that pending signal set is union of
per-thread and process-wide pending signal sets.
Michael Kerrisk
These interfaces have per-thread semantics
The page was previously fuzzy about whether the these interfaces
have process-wide or per-thread semantics. (E.g., now the
page states that the calling *thread* (not process) is suspended
until the signal is delivered.)
sigpending.2
Michael Kerrisk
Explain effect of fork() and execve() for pending signal set
Michael Kerrisk
Explain how thread's pending signal set is defined
The pending set is the union of per-thread pending signals
and process-wide pending signals.
sigprocmask.2
Michael Kerrisk
Explain effects of fork() and execve() for signal mask
splice.2
Michael Kerrisk
Note that SPLICE_F_MOVE is a no-op since kernel 2.6.21
syscall.2
Michael Kerrisk
Add more detail about wrapper functions
Add a few more details about work generally done by wrapper
functions. Note that syscall(2) performs the same steps.
tkill.2
Michael Kerrisk
EINVAL error can also occur for invalid TGID
The EINVAL error on an invalid TGID for tgkill() was
not documented; this change documents it.
utimensat.2
Michael Kerrisk
POSIX.1-2008 revision will likely affect FTMs for futimens()
Make it clear that the POSIX.1 revision that is likely
to affect the feature test macro requirements for futimens()
is POSIX.1-2008.
Nicolas François
Make various wordings a little more precise.
The times argument point to *an array of* structures, and the
man-page should say that consistently.
wait4.2
Michael Kerrisk
wait3() is a library function layered on wait4().
On Linux wait3() is a library function implemented on top
of wait4(). (Knowing this is useful when using strace(2),
for example.)
atan2.3
Nicolas François
Fix error in description of range or return value
In recent changes to the man page, mtk accidentally changed
the description of the return value range to -pi/2..pi/2;
the correct range is -pi..pi.
cmsg.3
Nicolas François
Add parentheses after macro names.
ctime.3
Michael Kerrisk
Clarify mktime()'s use of tm_isdst
Describe use of tm_isdst for input to mktime();
explain how mktime() modifies this field.
(This field is left unchanged in case of error.)
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=500178
Michael Kerrisk
Clarify wording for ctime_r() and asctime_r() to indicate that
the buffer must be at least 26 *bytes*.
Michael Kerrisk
Minor rewording of mktime() description.
floor.3
Nicolas François
floor.3: Fix error in description: s/smallest/largest/
hsearch.3
André Goddard Rosa
Call hdestroy() after using hash table created by hcreate(),
for the sake of completeness
mq_getattr.3
Michael Kerrisk
mq_getattr() and mq_setattr() are layered on mq_getsetattr(2)
mq_getattr() and mq_setattr() are library functions layered on
top of the mq_getsetattr(2) system call.
(This is useful info for users of strace(1).)
mq_receive.3
Michael Kerrisk
mq_send() is a library function layered on mq_timedreceive() syscall
This info is useful for users of strace(1).
mq_send.3
Michael Kerrisk
mq_send() is a library function layered on mq_timedsend() syscall
This info is useful for users of strace(1).
nextafter.3
Nicolas François
Make description more precise: s/next/largest/
readdir.3
Michael Kerrisk
SEE ALSO: add getdents(2)
Because readdir() is implemented on top of getdents(2).
realpath.3
Michael Kerrisk
Clarify that returned pathname is NULL terminated
Also clarify that null-byte is included in PATH_MAX limit.
proc.5
Michael Kerrisk
Rewrite and simplify description of /proc/mounts
Most of the relevant discussion is now under /proc/PID/mounts;
all that needs to be here is a mention of the pre-2.4.19
system-wide namespace situation, and a reference to the
discussion under /proc/PID/mounts.
Michael Kerrisk
Add description of /proc/PID/mounts
Largely cribbed from existing /proc/mounts discussion, which is
about to be rewritten.
mq_overview.7
Michael Kerrisk
Add mq_notify() to list of lib. functions and syscalls in MQ API
signal.7
Michael Kerrisk
Improve description in NAME section
Add mention of sigaltstack(2).
Describe syscalls that synchronously wait for a signal,
Give overview of syscalls that block until a signal is caught
Add overview of interfaces for sending signals.
Michael Kerrisk
Describe semantics w.r.t. fork() and execve()
Include text describing semantics of fork() and execve() for
signal dispositions, signal mask, and pending signal set.

Move the shell session text that demonstrates the use of
the example program so that it precedes the actual
example program. This makes the page consistent with the
majority of other pages.
Changes to individual pages
---------------------------
epoll_create.2
Michael Kerrisk
Say more about unused epoll_create() 'size' arg
Supply a little more explanation about why the 'size' argument
of epoll_create() is nowadays ignored.
eventfd.2
Michael Kerrisk
Remove crufty text relating to flags argument
Remove sentence saying that glibc adds a flags argument
to the syscall; that was only relevant for the older
eventfd() system call.
getdents.2
Christoph Hellwig
Fix text relating to DT_UNKNOWN and 'd_type' support
Some file systems provide partial support for 'dt_type',
returning DT_UNKNOWN for cases they don't support.
Update the discussion of 'd_type' and DT_UNKNOWN to
support this.
getpeername.2, getsockname.2
Michael Kerrisk
SEE ALSO: add ip(7) and unix(7)
getsockopt.2
Michael Kerrisk
EINVAL can also occur if 'optval' is invalid
In some cases, EINVAL can occur if 'optval' is invalid.
Note this, and point reader to an example in ip(7).
In response to:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=216092
inotify_init.2
pipe.2
timerfd_create.2
Michael Kerrisk
Clarify *_NONBLOCK description
Make it clear that the NONBLOCK flag sets an attribute in the new
open file description.
sched_yield.2
Michael Kerrisk
Rewrite description in terms of threads
The text formerly described the operation of sched_yield() in
terms of processes. It should be in terms of threads.
Michael Kerrisk
Add NOTES text on appropriate use of sched_yield()
Strategic calls to sched_yield() can be used to improve
performance, but unnecessary use should be avoided.
sigaction.2
Michael Kerrisk
Clarify that sa_mask affects the *per-thread* signal mask
The page didn't previously clearly explain the scope of the
signal mask that is affected by sa_mask.
signalfd.2
Michael Kerrisk
Remove crufty text relating to flags argument
Remove sentence saying that glibc adds a flags argument
to the syscall; that was only relevant for the older
signalfd() system call.
sigprocmask.2
Michael Kerrisk
Clarify that sigprocmask() operates on a per-thread mask
The first sentence of the page was vague on the scope of the
attribute changed by sigprocmask(). Reword to make this
clearer and add a sentence in NOTES to explicitly state that
the signal mask is a per-thread attribute.
socket.2
Michael Kerrisk
Document SOCK_NONBLOCK and SOCK_CLOEXEC flags
These flags, specified in the 'type' argument, are supported
since Linux 2.6.27.
socketpair.2
Michael Kerrisk
Refer to socket(2) for SOCK_CLOEXEC and SOCK_NONBLOCK
Refer the reader to socket(2) for a description of the SOCK_CLOEXEC
and SOCK_NONBLOCK flags, which are supported by socketpair() since
Linux 2.6.27.
syscalls.2
Michael Kerrisk
Add new 2.6.27 system calls
Add pipe2(), dup3(), epoll_create1(), inotify_init1(),
eventfd2(), signalfd4().
timerfd_create.2
Michael Kerrisk
Document timerfd_create() TFD_CLOEXEC and TFD_NONBLOCK
TFD_CLOEXEC and TFD_NONBLOCK are supported since LInux 2.6.27.
vfork.2
Michael Kerrisk
Clarify meaning of "child releases the parent's memory"
The man page was not explicit about how the memory used by
the child is released back to the parent.
ctime.3
Michael Kerrisk
ctime_r() and localtime_r() need not set 'timezone' and 'daylight'
The man page already noted that these functions need not set
'tzname', but things could be clearer: it tzset() is not called,
then the other two variables also are not set.
Also, clarify that ctime() does set 'timezone' and 'daylight'.
dlopen.3
Michael Kerrisk
LD_LIBRARY_PATH is inspected once, at program start-up
Make it clear that LD_LIBRARY_PATH is inspected *once*, at
program start-up. (Verified from source and by experiment.)
fmemopen.3
Michael Kerrisk
Document binary mode (mode 'b')
Glibc 2.9 adds support to fmemopen() for binary mode opens.
Binary mode is specified by inclusion of the letter 'b' in
the 'mode' argument.
getaddrinfo.3
Michael Kerrisk
Clarify error descriptions with some examples
Clarify the description of some errors by giving examples
that produce the errors. (Text added for EAI_SERVICE and
EAI_SOCKTYPE.)
Also, add an error case for EAI_BADFLAGS.
gethostbyname.3
Michael Kerrisk
Rationalize text on POSIX.1-2001 obsolete interfaces
POSIX.1 marks gethostbyname(), gethostbyaddr(), and 'h_errno'
as obsolete. The man page explained this, but with some
duplication. Remove the duplication, and otherwise tidy up
discussion of this point.
popen.3
Michael Kerrisk
Change one-line description in NAME
s%process I/O%pipe stream to or from a process%
Michael Kerrisk
Document 'e' (close-on-exec) flag
glibc 2.9 implements the 'e' flag in 'type', which sets the
close-on-exec flag on the underlying file descriptor.
raise.3
Michael Kerrisk
SEE ALSO: add pthread_kill(3)
readdir.3
Christoph Hellwig
Fix text relating to DT_UNKNOWN and 'd_type' support
(This mirrors the previous change to getdents.2)
Some file systems provide partial support for 'dt_type',
returning DT_UNKNOWN for cases they don't support.
Update the discussion of 'd_type' and DT_UNKNOWN to
support this.
strcpy.3
Jason Spiro
Strengthen warning about checking against buffer overruns
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=413940
tty_ioctl.4
Michael Kerrisk
Explain capability requirements for TIOCCONS
Explain capability requirements for TIOCCONS, and describe
changes in 2.6.10 relating to capabilities.
Michael Kerrisk
Explain capability requirements for various ioctls
For TIOCSLCKTRMIOS, TIOCSCTTY, TIOCEXCL, explain the exact
capability that is required (the text formerly just said "root"
in each case).
proc.5
Michael Kerrisk
Document /proc/sys/kernel/threads-max
Defines the system-wide limit on the number of threads (tasks).
utmp.5
Pierre Cazenave
It is just "other" who should not have write perms on utmp
The page was vague before, saying that utmp should not be
writable by any user. This isn't true: it can be, and
typically is, writable by user and group.
epoll.7
Michael Kerrisk
Mention epoll_create1() as part of epoll API
epoll_create1() was added in Linux 2.6.27, and extends the
functionality of epoll_create().
inotify.7
Michael Kerrisk
Mention inotify_init1() in overview of API
Discuss the new inotify_init1() system call in the overview of
the inotify API.
ip.7
Michael Kerrisk
Detail EINVAL error for IP_ADD_MEMBERSHIP socket option
In response to:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=216092
iso_8859-7.7
Lefteris Dimitroulakis
Add Drachma, Euro, and Greek Ypogegrammeni
Also, amend description of characters 0241 and 0242.
man-pages.7
Michael Kerrisk
Example shell sessions should have user input boldfaced
pthreads.7
Michael Kerrisk
Describe return value from pthreads functions
Describe the usual success (0) and failure (non-zero) returns,
and note that POSIX.1-2001 specifies that pthreads functions
can never fail with the error EINTR.
signal.7
Michael Kerrisk
Timeouts make socket interfaces non-restartable
If setsockopt() is used to set a timeout on a socket(),
then the various socket interfaces are not automatically
restarted, even if SA_RESTART is specified when
establishing the signal handler. Analogous behavior occurs
for the "stop signals" case.
socket.7
Michael Kerrisk
SEE ALSO: add unix(7)
ld.so.8
Michael Kerrisk
Document LD_USE_LOAD_BIAS
Drawing heavily on Jakub Jelinek's description in
http://sources.redhat.com/ml/libc-hacker/2003-11/msg00127.html
(Subject: [PATCH] Support LD_USE_LOAD_BIAS)
--inhibit-rpath is ignored for setuid/setgid ld.so
The --inhibit-rpath option is ignored if ld.so is setuid/setgid
(not if the executable is setuid/setgid).
Michael Kerrisk
Since glibc 2.4, setuid/setgid programs ignore LD_ORIGIN_PATH
Michael Kerrisk
Fix description of LD_PROFILE and LD_PROFILE_OUTPUT
Clarify that LD_PROFILE is pathname or a soname,
and identify name of profiling output file.
Fix description of LD_PROFILE_OUTPUT, which wasn't even close to
the truth. (But why did it remain unfixed for so many years?)
Michael Kerrisk
Since glibc 2.3.4, setuid/setgid programs ignore LD_DYNAMIC_WEAK
Michael Kerrisk
Since version 2.3.5, setuid/setgid programs ignore LD_SHOW_AUXV
Michael Kerrisk
Reorder lists of LD_* environment variables alphabetically
Michael Kerrisk
Since glibc 2.3.4, setuid/setgid programs ignore LD_DEBUG

Michael Kerrisk
Explain _np suffix
Add text to CONFORMING TO explaining that the "_np"
suffix is because these functions are non-portable.
Changes to individual pages
---------------------------
sched_setaffinity.2
Michael Kerrisk
SEE ALSO: add sched_getcpu(3)
sched_setaffinity.2
Michael Kerrisk
SEE ALSO: Add pthread_setaffinity_np(3)
sched_setaffinity.2
Michael Kerrisk
Clarify EINVAL error for cpusetsize < kernel mask size
For sched_setaffinity(), the EINVAL error that occurs
if 'cpusetsize' is smaller than the kernel CPU set size only
occurs with kernels before 2.6.9.
vfork.2
Michael Kerrisk
Child holds parent's memory until execve() or *termination*
The page was phrased in a few places to describe the child as
holding the parent's memory until the child does an execve(2)
or an _exit(2). The latter case should really be the more
general process termination (i.e., either _exit(2) or abnormal
termination).
clock_getres.3
Michael Kerrisk
CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID not setabble
According to POSIX.1-2001, the CLOCK_PROCESS_CPUTIME_ID and
CLOCK_THREAD_CPUTIME_ID clocks should be settable, but
currently they are not.
pthread_attr_setstacksize.3
Michael Kerrisk, after a report by Karsten Weiss
EINVAL occurs on some systems if stacksize != page-size
On MacOS X at least, pthread_attr_setstacksize(3) can fail
with EINVAL if 'stacksize' is not a multiple of the system
page size. Best to mention this so as to aid people writing
portable programs.
pthread_create.3
Karsten Weiss
Fix bug in EXAMPLE program
The calloc() line should read like this instead:
tinfo = calloc(num_threads, sizeof(struct thread_info));
pthread_exit.3
Michael Kerrisk
BUGS: thread group with a dead leader and stop signals
Document the bug that can occur when a stop signal
is sent to a thread group whose leader has terminated.

resolver.3
Michael Kerrisk
Fix prototype of dn_expand()
The 4th argument is "char *", not "unsigned char *".
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504708
epoll.7
Michael Kerrisk
Fix error handling after accept() in example code
Simply continuing after an error is in most cases wrong,
and can lead to infinite loops (e.g., for EMFILE).
So handle an error by terminating.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504202
epoll.7
Michael Kerrisk
Add error handling for epoll_wait() call in example code
epoll.7
Michael Kerrisk
Improve example code
Fill in some gaps in example code (variable declarations,
adding listening socket to epoll set).
Give variables more meaningful names.
Other minor changes.

iso_8859-7.7
Lefteris Dimitroulakis
Add characters for Drachma and Greek Ypogegrammeni
Lines for these two characters were added in the previous patch,
but the actual characters were not included in the 4th column
of the table. This fixes that.
pthreads.7
Michael Kerrisk
Add a section describing thread IDs
In particular, note that in each pthreads function that takes
a thread ID argument, that ID by definition refers to a thread
in the same process as the caller.

New and rewritten pages
-----------------------
CPU_SET.3
Michael Kerrisk
New page documenting CPU_* macros
This page contains material moved out of sched_setscheduler(2).
It overwrites a previously existing link file with the same name.
Michael Kerrisk
Add description of macros for dynamically allocated CPU sets
Add descriptions of CPU_ALLOC(), CPU_ALLOC_SIZE(), CPU_FREE(),
CPU_SET_S(), CPU_CLR_S(), CPU_ISSET_S(), CPU_ZERO_S(),
CPU_COUNT_S(), CPU_AND_S(), CPU_OR_S(), CPU_XOR_S(), and
CPU_EQUAL_S().
Michael Kerrisk
Add documentation of CPU_COUNT()
Michael Kerrisk
Add description of CPU_AND(), CPU_OR, CPU_XOR(), and CPU_EQUAL()
Plus a few other small clean-ups of the text
Michael Kerrisk
Various improvements in DESCRIPTION
After review comments by Bert Wesarg:
* Explain that cpu_set_t is a bitset, but should be considered
opaque.
* A CPU set can be duplicated with memset().
* Size of a CPU set is rounded up to size of long.
* CPU_SETSIZE is in bits, but the setsize argument is in bytes.
Michael Kerrisk
Document CPU_ALLOC()/CPU_ALLOC_SIZE() bug
These macros return twice what they should because of thinko
in glibc 2.8 and earlier. The bug is fixed for glibc 2.9.
http://sourceware.org/bugzilla/show_bug.cgi?id=7029
Michael Kerrisk
NOTES: Discuss use of types in "prototypes" for these macros
The SYNOPSIS shows types for arguments and return values, but
these are really just suggestions: since the interfaces are
macros, the compiler won't catch all violations of
the "type rules". Warn the reader of this.

Global changes
--------------
clone.2
mount.2
unshare.2
proc.5
path_resolution.7
Michael Kerrisk
Global fix: s/namespace/mount-point namespace/, as appropriate
In recent times, a number of other namespace flags have been
added to clone(2). As such, it is no longer clear to use
the generic term "namespace" to refer to the particular
namespace controlled by CLONE_NEWNS; instead, use the
term "mount-point namespace".
Michael Kerrisk
Global fix: s/mount-point namespace/mount namespace/
This is more consistent with the term "mounts namespace"
used in the 2008 ACM SIGOPS paper, "Virtual servers
and and checkpoint/restart in mainstream Linux".
(I avoided the "s", because using the plural strikes me
as klunky English, and anyway we don't talk about
the "PIDs namespace" or the "networks namespace", etc..)

Global fix: eliminate mention of the obsolete sysctl(2) interface

instead be in terms of /proc interfaces.

pthread_tryjoin_np.3
Michael Kerrisk
Use consistent error-handling function names
Many older pages use a handle_error() macro to do simple
error handling from system and library function calls.
Switch these pages to do similar.
Changes to individual pages
---------------------------
time.1
Michael Kerrisk
Note that some shells have a 'time' built-in command
Therefore, to access the functionality described on this page,
it may be necessary to specify the full pathname.
clone.2
Michael Kerrisk
Place list of CLONE_* flags in alphabetical order
(No content changes.)
fsync.2
Michael Kerrisk
Update feature test macro requirements for fsync()
Since glibc 2.8, the fsync() declaration is also exposed if
_POSIX_C_SOURCE >= 200112L
sched_setaffinity.2
Michael Kerrisk
Add note on system-imposed restrictions on CPUs actually used
After Loic Domaigne's suggestion for pthread_setaffinity_np(3), add
similar text to this page noting that the system silently
limits the set of CPUs on which the process actually runs to
the set of CPUs physically present and the limits imposed by
cpuset(7).
sched_setaffinity.2
Michael Kerrisk
Removed discussion of CPU_* macros()
These macros are now moving to a separate page.
Michael Kerrisk
Refer reader to pthread_setaffinity_np(3)
pthread_setaffinity_np() is preferable for setting
thread CPU affinity if using the POSIX threads API.
sysctl.2
Michael Kerrisk
Add prominent warning against using this system call
This was already stated under NOTES, but make it even more
prominent by adding a sentence at the start of the DESCRIPTION.
uname.2
Michael Kerrisk
Add C comments describing fields in utsname structure
atan2.3
Stefano Teso
Fix description of range of function value return
The range is not [-pi/2, pi/2], but [-pi, pi].
(mtk: This error was reported by Nicolas Francois, and
should have been fixed in 3.11, but somewhere along the way,
the fix got lost.)
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=506299
bindresvport.3
Michael Kerrisk
Since glibc 2.8, EPFNOSUPPORT error is now EAFNOSUPPORT
Glibc switched to using a POSIX-specified error code for
this error case.
http://bugs.linuxbase.org/show_bug.cgi?id=2375
clock_getres.3
Michael Kerrisk
CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID not settable
According to POSIX.1-2001, the CLOCK_PROCESS_CPUTIME_ID and
CLOCK_THREAD_CPUTIME_ID clocks should be settable, but
currently they are not.
getgrnam.3
Michael Kerrisk
Clarify and add more detail in RETURN VALUE description
The page was a bit fuzzy in describing the return values for
various cases. In particular, it needed to be more explicit
in describing what happens for the "not found" case.
This is an analogous change to the change for
getpwnam.3, made after Andreas Henriksson's report.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504787
Michael Kerrisk
Rename arguments to getgrnam_r() and getgrgid_r()
s/gbuf/grp/ and s/gbufp/result/, for consistency
with POSIX.1 argument names.
Michael Kerrisk
Clarify RETURN VALUE description
The page was a bit fuzzy in describing the return values for
various cases. In particular, it needed to be more explicit
in describing what happens for the "not found" case.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504708
getpwnam.3
Michael Kerrisk
Rename arguments to getpwnam_r() and getpwuid_r()
s/pwbuf/pwd/ and s/pwbufp/result/, for consistency
with POSIX.1 argument names.
Michael Kerrisk
Clarify and add more detail in RETURN VALUE description
The page was a bit fuzzy in describing the return values for
various cases. In particular, it needed to be more explicit
in describing what happens for the "not found" case.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504787
Michael Kerrisk
Add an EXAMPLE program for getpwnam_r()
inet_ntop.3
Michael Kerrisk
Rename 'cnt' argument to 'size'
This is consistent with POSIX.1, and also a more sensible name.
Michael Kerrisk
Rework text describing 'size' argument
(After a suggestion by Vegard Nossum.)
Also made a few other small rewordings to in the initial
paragraph.
makecontext.3
Michael Kerrisk
Add text on use of pointer arguments to makecontext()
Passing pointer arguments to makecontext() is possible,
but only on some architectures, and with no guarantees
of portability.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504699
pthread_attr_setaffinity_np.3
Michael Kerrisk
Various fixes after review by Loic Domaigne
Reviewed-by: Loic Domaigne
pthread_attr_setaffinity_np.3
pthread_setaffinity_np.3
Michael Kerrisk
Update to reflect new location of CPU_*() documentation
The CPU_*() macros are now documented in CPU_SET.3;
update to reflect that fact.
Michael Kerrisk
Remove redundant text relating to CPU sets
Information about CPU_SETSIZE can be found in CPU_SET.3, so
remove discussion of it here.
pthread_attr_setschedparam.3
pthread_setschedparam.3
Michael Kerrisk
Remove text saying that only sched_priority is required by POSIX.1
Loic Domaigne points out that if a system implements
SCHED_SPORADIC (which Linux does not), then other
fields are also specified in sched_param. The simple
solution is just to remove that phrase from the man
page.
pthread_cancel.3
pthread_detach.3
pthread_join.3
pthread_setaffinity_np.3
Michael Kerrisk
Make text of ESRCH error consistent
pthread_setaffinity_np.3
Michael Kerrisk
Add text to EINVAL error mentioning cpuset(7)
Michael Kerrisk
Various improvements after review by Loïc Domaigne
Various fix-ups after Loïc's review.
Reviewed-by: Loïc Domaigne
pthread_setschedparam.3
Michael Kerrisk
PTHREAD_INHERIT_SCHED is default for inherit scheduler attribute
In EXAMPLE, note that PTHREAD_INHERIT_SCHED is the default for
the inherit scheduler attribute attribute.
syslog.3
Masanari Iida
LOG_KERN messages can't be generated from user processes
Masanari notes that this is an FAQ for logger(1) and that
Solaris and FreeBSD document this point in syslog(3).
The glibc info page also hides this comment in its source:
Internally, there is also LOG_KERN, but LOG_KERN == 0,
which means if you try to use it here, just selects default.
proc.5
Ivana Varekova
Fix reference to kernel source file
Use relative reference to Documentation/mtrr.txt.
arp.7
Michael Kerrisk
Add kernel version numbers for /proc interfaces
cpuset.7
Michael Kerrisk
SEE ALSO: add CPU_SET(3)
epoll.7
Michael Kerrisk
Note glibc version that added epoll support
icmp.7
Michael Kerrisk
Add kernel version numbers to /proc file descriptions
inotify.7
Vegard Nossum
Fix description of max_user_watches
It seems that inotify(7) is wrong here:
"/proc/sys/fs/inotify/max_user_watches
This specifies a limit on the number of watches that can be
associated with each inotify instance."
On my system, the default value for this variable is 8192. But I
cannot create more than 8192 watches in total for the same UID
even when they are on different inotify instances. So I suggest
to rephrase this as: "This specifies an upper limit on the
number of watches that can be created per real user ID."
ip.7
Michael Kerrisk
Reorder socket options alphabetically
Michael Kerrisk
Added kernel version numbers for IP_* socket options
Michael Kerrisk
Relocate kernel version information for IP_PMTUDISC_PROBE
Michael Kerrisk
Add kernel version numbers for /proc/sys/net/ipv4/ip_* files

pthreads.7
Michael Kerrisk
Add section on cancellation points
This section includes a list of the functions that must and
may be cancellation points.
Michael Kerrisk
Rework, and fix small error in, thread-safe function list
Integrate the changes that occurred in POSIX.1-2008 into the
main list (to be consistent with the list, elsewhere on this
page, of functions that are cancellation points).
Also, fix an error that said that strerror() was added to
the list in POSIX.1-2008. It was strsignal() that was
added. (strerror() was already in the list in POSIX.1-2001.)
Michael Kerrisk
Tweak text on sigpause() cancellation point
In POSIX.1-2009, this function moves from the "must be"
to the "may be" list.
Michael Kerrisk
Add ref to signal(7) for further info on use of real-time signals
signal(7) provides some further details on the use of real-time
signals by the two Linux threading implementations.

_exit.2
Michael Kerrisk
Since glibc 2.3, the exit() wrapper function invokes exit_group(2)
This information is useful to users of strace(1).
accept.2
Michael Kerrisk
Clarify details when returned address is truncated
If the returned address is truncated, the 'addrlen' argument
indicates the actual size of the address, rather than a count
of the number of bytes in the truncated buffer.
Also clarify that if 'addr' argument is NULL, then 'addrlen'
should is unused, and should also be NULL.

gethostname.2
Michael Kerrisk
Note that HOST_NAME_MAX is 64 on Linux
Also note that in pre-1.0 days, the limit on hostnames
was 8 bytes.
getpeername.2
Michael Kerrisk
Note that returned address may be truncated if buffer is too small
getsid.2
Michael Kerrisk
Simplified version information and moved to a new VERSIONS section
getsockname.2
Michael Kerrisk
Note that returned address is truncated if buffer is too small
mknod.2
Michael Kerrisk
Refer reader to makedev(3) to build a device ID
mmap.2
Michael Kerrisk
Loosen language around how 'addr' hint is interpreted
Mel Gorman reported that in Linux 2.6.27, 'addr' is rounded
down to a page boundary.
Before kernel 2.6.26, if 'addr' was taken as a hint, it was
rounded up to the next page boundary. Since Linux 2.6.24,
it is rounded down. Therefore, loosen the description of
this point to say that the address is rounded to "a nearby
page boundary".
open.2
Michael Kerrisk
EFBIG error is now EOVERFLOW (since Linux 2.6.24)
When a 32-bit app opens a file whose size is too big to be
represented in 31-bits, POSIX.1 specifies the error EOVERFLOW.
Linux used to give EFBIG for this case, but 2.6.24 fixed this.
Also, add some text to describe the error scenario in
more detail.
pread.2
Michael Kerrisk
Note that glibc emulation for these calls uses lseek(2)
(This makes it clearer that the emulated calls are not atomic.)
recv.2
send.2
Michael Kerrisk
Make names of "address" and "address length" args more consistent
Make the names of these arguments more consistent with other
sockets man pages.
recv.2
Michael Kerrisk
Clarify details when returned address is truncated
If the recvfrom() returned address is truncated, the 'fromlen'
argument indicates the actual size of the address, rather than
a count of the number of bytes in the truncated buffer.
Also clarify that the 'from' argument can be NULL, in which
case 'fromlen' should is unused, and should also be NULL.
Michael Kerrisk
Internet datagram and netlink sockets support MSG_TRUNC for recv(2)
Internet datagram (since Linux 2.4.27/2.6.8),
and netlink (since Linux 2.6.22) sockets support
the MSG_TRUNC flag for recv(2).
select.2
Michael Kerrisk
Rewrote text describing feature test macros requirement for pselect()
select_tut.2
Michael Kerrisk
Fix SHUT_FD* macros in example program
Add "do {} while (0)"
set_thread_area.2
Michael Kerrisk
Note that glibc provides no wrapper for this system call
setfsgid.2
setfsuid.2
Michael Kerrisk
Simplify version information and move to a VERSIONS section
setsid.2
Michael Kerrisk
Rework RETURN VALUE section; add an ERRORS section
setup.2
Michael Kerrisk
Relocate some CONFORMING TO text to VERSIONS and NOTES
stat.2
Michael Kerrisk

Michael Kerrisk
Refer reader to major() and minor() to decompose a device ID
syscalls.2
Michael Kerrisk
Fix version numbers for a few system calls
Some 2.6 system calls were wrongly mentioned as also being
backported into a 2.4.x kernel.
uname.2
Michael Kerrisk
DESCRIPTION: Point reader at NOTES for further info on field lengths
atan.3
Andries E. Brouwer
Fix return value description
The correct range for the return value is [-pi/2,pi/2].
(mtk's fix in the last change to the return value text was
a botch-up of a (correct) suggestion by Nicolas Francois.)
atexit.3
Michael Kerrisk
atexit() and on_exit(3) register functions on the same list
Michael Kerrisk
Terminating registered function using longjmp() is undefined
According to POSIX.1, using longjmp() to terminate execution of
a function registered using atexit() produces undefined results.
Michael Kerrisk
Calling exit(3) more than once produces undefined results
If an exit handler itself calls exit(3), the results are
undefined (see the POSIX.1-2001 specification of exit(3)).
Michael Kerrisk
The same exit handler may be registered multiple times
Michael Kerrisk
Calling _exit(2) terminates processing of exit handlers
Michael Kerrisk
Terminating registered function using longjmp() is undefined
According to POSIX.1, using longjmp() to terminate execution of
a function registered using atexit() produces undefined results.
bindresvport.3
Mats Wichmann
SYNOPSIS: s/\*\*/*/ in prototype
Michael Kerrisk
Fix errors regarding port used, plus other rewrites
Glibc's bindresvport() takes no notice of sin->sin_port:
it always returns an arbitrary reserved port in the
anonymous range (512-1023). (Reported by Mats Wichmann.)
Also:
* Add EADDRINUSE and EACCES errors.
* Mention use of getsockname(2).
* Other minor rewrites and reorderings of the text.
* Explicitly note that glib's bindresvport() ignores
sin->sin_port.
* Change license There's now virtually no text remaining from
the 1.70 version of this page.

Describe confusing dladdr() behavior
dladdr() will act unexpectedly if called from non-pic code on a
compile-time-generated function pointer.
fmemopen.3

fopencookie.3
Petr Baudis

getaddrinfo.3
Petr Baudis
Document results ordering and /etc/gai.conf
This patch documents the order of the getaddrinfo(3) results
(RFC 3484), how should the application deal with that,
mentions the extremely common cause of having multiple
results per query (both IPv4 and IPv6 addresses available)
and mentions /etc/gai.conf.
(mtk: Minor tweaks, and note glibc version for /etc/gai.conf)
isatty.3
Michael Kerrisk
Complete rewrite of this page, with rather more detail
memmem.3
Michael Kerrisk
Remove sentence saying that libc 5.0.9 is still widely used
That was a *long* time ago.
on_exit.3
Michael Kerrisk
Document handling of registrations on fork(2) and execve(2)
Treatment in these cases is the same as for atexit(3).
Michael Kerrisk
Arg given to registered function is status from *last* call to exit()
It's a subtle point, but if a registered function itself
calls exit(3), then subsequent functions that were registered
with on_exit(3) will see the exit status given to the more
recent exit(3) call.
Michael Kerrisk
Note that same function may be registered multiple times
setlocale.3
locale.7
Michael Kerrisk
Clean up the description of LANGUAGE environment variable
Clean up the $LANGUAGE description, by removing bogus comments
from setlocale(3) and expanding the mention in locale(7).
Maybe you will decide that a more detailed description
should be left to the gettext(3) documentation, but I
actually care about the invisible part of the patch more
since the comments have put me off the track initially
($LANGUAGE has nothing to do with setlocale(3) and is
completely isolated to gettext, as obvious from the
glibc sources).
proc.5
Michael Kerrisk
/proc/stat: s/minor/disk_idx/ in description of /proc/stat
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=225619
capabilities.7
Drake Wilson
Various minor fixes as per Debian bug 471029
The relevant pieces of
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=471029 are:
- Delete duplicate subentry for KEYCTL_CHOWN/KEYCTL_SETPERM
operations in the CAP_SYS_ADMIN entry. (It feels like that
capability entry should be converted to a list, but I've
left it in semicolon-delimited form for now.)
- Remove text about ENFILE from the text about the
/proc/sys/fs/file-max limit in the CAP_SYS_ADMIN entry, since
this is already described in the man pages for the relevant
ofile-creating system calls.
- Correct or clarify a few other bits of grammar and such;
see the diff file itself for details.
socket.7
Michael Kerrisk
SEE ALSO: add tcp(7) and udp(7)
tcp.7
Michael Kerrisk
Relocate out-of-band data discussion
Move to a new subsection entitled "Sockets API".
Michael Kerrisk
Note that MSG_PEEK can be used on out-of-band data
time.7
Michael Kerrisk
SEE ALSO: add clock_gettime(3)
unix.7
Michael Kerrisk
Unix domain sockets don't support the recv() MSG_TRUNC flag

This is consistent with the recent change in tcp(7).

printf.3
Michael Kerrisk
Source and destination buffers may not overlap for *s*printf()
http://sourceware.org/bugzilla/show_bug.cgi?id=7075
Some existing code relies on techniques like the following to
append text to a buffer:
$ cat s.c
#include <stdio.h>
char buf[80] = "not ";
main()
{
sprintf(buf, "%sfail", buf);
puts(buf);
return 0;
}
$ cc s.c
$ ./a.out
not fail
However, the standards say the results are undefined if source
and destination buffers overlap, and with suitable compiler
options, recent changes can cause unexpected results:
$ cc -v 2>&1 | grep gcc
gcc version 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036] (SUSE Linux)
$ cc -D_FORTIFY_SOURCE -O2 s.c

Correct NOTES section on reloading configuration files
It behaved this way at least since
"Sun Oct 18 15:02:11 1998 +0000",
some four months after including the nscd implementation
in glibc. But there does seem to be a short window between
glibc-2.1 and glibc-2.1.3 when nscd -i was not available,
I don't think it's worth muddling the point of the page
with that, though.

not 3. Therefore fix those pages that currently refer to these
interfaces as being in Section 3.

Various pages
Kir Kolyshkin
Trivial punctuation fixes in SEE ALSO
In SEE ALSO, when a few man pages are referenced, those
are divided by commas. Every reference is on a separate
line, and all lines but the last one should end with
comma. I spotted one place where there is no comma in
between references, and mocked up an awk script to find
similar places:
for f in man*/*; do
awk '
/^.SH ["]SEE ALSO["]/ {
sa=1; print "== " FILENAME " =="; print; next
}
/^\.(PP|SH)/ {
sa=0; no=0; next
}
/^\.BR/ {
if (sa==1) {
print;
if (no == 1)
print "Missing comma in " FILENAME " +" FNR-1; no=0
}
}
/^\.BR .*)$/ {
if (sa==1)
no=1;
next
}
/\.\\"/ {next}
/.*/ {
if (sa==1) {
print; next
}
}
' $f;
done | fgrep 'Missing comma'
This patch fixes all the places found by the above script.
Also, there is an extra dot at the end of uri.7 "SEE ALSO"
section. Removed as per man-pages(7) recommendation.

splice.2
Mark Hills
ERRORS: Add EINVAL case for file opened O_APPEND
Target file cannot be opened in append (O_APPEND) mode
In kernels prior to v2.6.27 splice() to a file in
append mode is broken, and since that version it is
disallowed. It is possible this behaviour may change
in the future; see the kernel commit message
(efc968d450e013049a662d22727cf132618dcb2f) for more
information.

Make source layout of 'Link with' text consistent with other pages
No actual change to formatted output, but this makes the
page sources more consistent for the purpose of grepping, etc.
mempcpy.3
signbit.3
significand.3
Michael Kerrisk
Global fix: acknowledge FSF in copyright
These pages are heavily based on original material in
glibc info pages, but the comments in the source of the pages
did not acknowledge the FSF copyright on the original material.
Fix that.
accept.2
read.2
recv.2
send.2
write.2
Michael Kerrisk
Fix discussion of EAGAIN/EWOULDBLOCK errors
For a non-blocking socket, POSIX.1-2001/2008 allow either
EAGAIN or EWOULDBLOCK to be returned in cases where a call
would have blocked. Although these constants are defined
with the same value on most Linux architectures (PA-RISC
is the exception), POSIX.1 does not require them to have
the same value. Therefore, a portable application using
the sockets API should test for both errors when checking
this case.
(NB POSIX.1 only mentions EWOULDBLOCK in the context of
the sockets interfaces.)
Change made after a note cross-posted on linux-arch@vger,

Add explicit character set encoding to first line of source
Nowadays mandb has provision to understand a character set
encoding that is explicitly indicated in the first line
of the source. As pointed out by Colin Watson, including
such an explicit indication on pages encoded in anything
other than ISO 8859-1 or UTF-8 is useful for man-pages
that aren't shipped in UTF-8.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=519209
and for some other background (responded to by Colin Watson
in the above report):

Changes to individual pages
---------------------------
fallocate.2
Michael Kerrisk
VERSIONS: glibc support is provided since version 2.10
fcntl.2
Michael Kerrisk
Remove mention of EWOULDBLOCK from discussion of mandatory locking
In the kernel, the error on encountering a mandatory lock is
EAGAIN. Although EAGAIN and EWOULDBLOCK are the same on
most Linux architectures, on some they are not, so don't
mention EWOULDBLOCK as it is misleading. (Mea culpa.)
getcontext.2
Michael Kerrisk
Note that POSIX.1-2008 removes the specification of getcontext()
getitimer.2
Michael Kerrisk
Note that POSIX.1-2008 recommends POSIX timers API instead of this API
gettimeofday.2
Michael Kerrisk
Note that POSIX.1-2008 recommends clock_gettime() instead of this API
ptrace.2
Michael Kerrisk
Note use of 'data' for PTRACE_SYS{CALL,EMU} and PTRACE_*_SINGLESTEP
These operations use the 'data' argument as a signal number,
like PTRACE_CONT.
ptrace.2
Mike Frysinger
only reference <sys/user.h>
The kernel no longer installs linux/user.h, so update
references to sys/user.h.
recv.2
Michael Kerrisk
Add 'iovec' defn to defn of 'msghdr' structure
The 'msghdr' structure includes a field of type 'iovec',
so show the definition of that structure in this page.
rename.2
Michael Kerrisk
Make ENOENT description consistent with POSIX.1-2008
timerfd_create.2
Michael Kerrisk
ERRORS: add EINVAL for invalid 'flags' for timer_settime()
truncate.2
Michael Kerrisk
SYNOPSIS: Fix description of feature test macro requirements
After a report by Arvid Norlander.
bcopy.3
Michael Kerrisk
Note that POSIX.1-2008 removes specification of bcopy()
bsd_signal.3
Michael Kerrisk
Note that POSIX.1-2008 recommends sigaction(2) instead of this API
ctime.3
Michael Kerrisk
Note that POSIX.1-2008 recommends strftime(3) instead of these functions
ecvt.3
Michael Kerrisk
Note that POSIX.1-2008 recommends sprintf(3) instead of these functions
gcvt.3
Michael Kerrisk
Note that POSIX.1-2008 recommends sprintf(3) instead of this function
getcwd.3
Michael Kerrisk
Note that getcwd() should be used instead of the obsolete getwd()
getgrent.3
Michael Kerrisk
Returned buffer may be statically allocated and overwritten by
later calls
gethostbyname.3
Michael Kerrisk
POSIX.1-2008 recommends getaddrinfo(3) and getnameinfo(3) instead
getnetent_r.3
Michael Kerrisk
Fix function name in text: s/getnetbynumber_r/getnetbyaddr_r/
The SYNOPSIS showed the right function name (getnetbyaddr_r),
but the text repeatedly used the wrong name (getnetbynumber_r).
Probably, this was a cut-and-paste error.
getpwent.3
Michael Kerrisk
Returned buffer may be statically allocated and overwritten by
later calls
index.3
Michael Kerrisk
Note that POSIX.1-2008 recommends strchr(3) and strrchr(3) instead
isalpha.3
Michael Kerrisk
Explain why POSIX.1-2008 marks isascii(3) obsolete
lockf.3
Nikanth Karthikesan
Update pointer to documentation in kernel source
makecontext.3
Michael Kerrisk
Note that POSIX.1-2008 recommends the use of POSIX threads instead
mq_notify.3
Michael Kerrisk
Document the POSIX.1-2008 optional EINVAL error
POSIX.1-2008 allows an optional EINVAL error if
notification==NULL and the caller is not currently
registered to receive notifications.
posix_fallocate.3
Michael Kerrisk
Clarify that EINVAL also occurs of 'len' *equals* zero
See http://bugzilla.kernel.org/show_bug.cgi?id=12919

Michael Kerrisk
Fix error in DESCRIPTION: s/pthread_create/pthread_exit/
realpath.3
Michael Kerrisk
Rework resolved_path==NULL discussion w.r.t. POSIX.1-200[18]
Although the page already mentioned the resolved_path==NULL
feature, and that this feature was added in POSIX.1-2008, there
was still some crufty text in BUGS that hadn't been updated to
reflect the POSIX.1-2008 changes.
Also, some other minor wording and grammar fixes.
scalb.3
Michael Kerrisk
Note that POSIX.1-2008 recommends scalbln*(3) instead
seekdir.3
Michael Kerrisk
SYNOPSIS: Fix type of 'offset' argument: s/off_t/long/
And add a NOTES section pointing out that 'off_t'
was indeed used in glibc 2.1.1 and earlier.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=519230
sem_post.3
Michael Kerrisk
Document EOVERFLOW error
shm_open.3
Michael Kerrisk
Recast discussion on name length to exclude terminating NULL byte
Probably it's clearer to describe the length of the IPC object
name as a count that excludes the null terminator.
siginterrupt.3
Michael Kerrisk
Note that POSIX.1-2008 recommends sigaction() instead
sigset.3
Michael Kerrisk
Note APIs that POSIX.1-2008 recommends instead of these obsolete APIs
strftime.3
Michael Kerrisk
Small fix to description of %G
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=516677
strftime.3
Michael Kerrisk
Add details on ISO 8601 week-based dates
ISO 8602 week-based dates are relevant for %G, %g, and %V,
and the existing details on these dates are a little thin.
strftime.3
Michael Kerrisk
Remove mention of year from ISO 8601 standard
The text mentioned the 1988 8601 standard, but there have
already been two revisions of the standard since then, so
simply remove mention of the year.
telldir.3
Michael Kerrisk
SYNOPSIS: Fix return type: s/off_t/long/
And add a NOTES section pointing out that 'off_t'
was indeed used in glibc 2.1.1 and earlier.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=519230

Michael Kerrisk
Add description of /srv
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=520904
ip.7
Michael Kerrisk
Fix type used to declare sin6_port
The page should use the type specified by POSIX,
rather than the (equivalent) type used in the kernel
ipv6.7
Teddy Hogeborn
Fix types used to declare sin6_family and sin6_port
The page should use the types specified by POSIX,
rather than the (equivalent) types used in the kernel.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=517074
mq_overview.7
Michael Kerrisk
Recast discussion on name length to exclude terminating NULL byte
Probably it's clearer to describe the length of the IPC object
name as a count that excludes the null terminator.
rtld-audit.7
Michael Kerrisk
Note that multiple libraries in LD_AUDIT doesn't work
This is reportedly fixed in glibc 2.10.
See http://sourceware.org/bugzilla/show_bug.cgi?id=9733
sem_overview.7
Michael Kerrisk
Fix discussion of length of semaphore names
Because of the "sem." prefix added by glibc to a semaphore
name, the limit on the length of the name (excluding the
terminating null byte) is 251 characters.

Changes to individual pages
---------------------------
clone.2
Michael Kerrisk
Rewrite crufty text about number of args in older version of clone()
Some bit rot had crept in regarding the discussion of the
number of arguments in older versions of this syscall.
Simplify the text to just say that Linux 2.4 and earlier
didn't have ptid, tls, and ctid arguments.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=533868
Michael Kerrisk
Fix version number for CLONE_NEWIPC
It's 2.6.19, not 2.4.19.
Michael Kerrisk
Fix errors in argument names in text (ptid, ctd)
execve.2
Mike Frysinger
Remove erroneous statement that pending signal set is cleared
on execve(2).
fcntl.2
Michael Kerrisk
The kernel source file mandatory.txt is now mandatory-locking.txt
Michael Kerrisk
The Documentation/* files are now in Documentation/filesystems
flock.2
Michael Kerrisk
Remove unneeded reference to Documentation/mandatory.txt
Mandatory locks are only implemented by fcntl() locking
Michael Kerrisk
The Documentation/* files are now in Documentation/filesystems
fork.2
Jeff Moyer
Document fork() behaviour for the Linux native AIO io_context
It was noted on lkml that the fork behaviour is documented
for the POSIX AIO calls, but not for the Linux native calls.
Here is a patch which adds a small blurb that folks will
hopefully find useful.
Upon fork(), the child process does not inherit the
io_context_t data structures returned by io_setup,
and thus cannot submit further asynchronous I/O or
reap event completions for said contexts.
getdents.2
Michael Kerrisk
The d_type field is fully supported on Btrfs
mount.2
Michael Kerrisk
Document MS_STRICTATIME, update description of MS_RELATIME
Starting with Linux 2.6.30, the MS_RELATIME behavior became
the default, and MS_STRICTATIME is required to obtain the
traditional semantics.
poll.2
Michael Kerrisk
Remove EBADF error from ERRORS
As reported by Motohiro:
"man poll" describe this error code.
>ERRORS
> EBADF An invalid file descriptor was given in one of the sets.
but current kernel implementation ignore invalid file descriptor,
not return EBADF.
...
In the other hand, SUSv3 talk about
> POLLNVAL
> The specified fd value is invalid. This flag is only valid in the
> revents member; it shall ignored in the events member.
and
> If the value of fd is less than 0, events shall be ignored, and
> ireevents shall be set to 0 in that entry on return from poll().
but, no desribe EBADF.
(see http://www.opengroup.org/onlinepubs/009695399/functions/poll.html)
So, I think the implementation is correct.
Why don't we remove EBADF description?
sigaction.2

NOTES: there is no file descriptor associated with the returned stream
Alexander Lamaison pointed out that this is not obvious
from the documentation, citing an example with passing the
FILE * handle to a function that tries to fstat() its
fileno() in order to determine the buffer size.
Michael Kerrisk
CONFORMING TO: remove note that these functions are GNU extensions
That sentence is now redundant, since these functions
are added in POSIX.1-2008.

It should be
double complex z = cexp(I * pi); instead.

Gallmeister and Lewine are rather old books. Probably,
there are better books to consult nowadays, and anyway,
this man page isn't intended to be a bibliography.

Changes to individual pages
---------------------------
execve.2
pipe.2
tee.2
fmemopen.3
mq_notify.3
qsort.3
Michael Kerrisk
Replace use of assert() by code that checks argc
See http://bugzilla.kernel.org/show_bug.cgi?id=13569
As noted by Andrey:
The purpose of the assert macro, defined in <assert.h>,
is to provide a tool to check for programming mistakes
or program logic errors. However, the assert macro must
never be used to perform checks for run time errors,
since, with the NDEBUG macro defined, expressions within
the assert macro invocations are not evaluated/checked
for, resulting in behavior that was not originally intended.
...
The pages affected in the core package are
execve(2)
pipe(2)
tee(2)
fmemopen(3)
mq_notify(3)
qsort(3)
getrusage.2
Michael Kerrisk
ru_inblock and ru_oublock are now implemented
These fields of the rusage structure are filled in since
Linux 2.6.22.
mmap.2
Michael Kerrisk
Add brief documentation of MAP_HUGETLB
This flag is new in 2.6.32, and serves a similar
purpose to the shmget() SHM_HUGETLB flag.
open.2
Christoph Hellwig
add some comments on O_SYNC and friends
poll.2
Michael Kerrisk
Clarify wording describing of 'nfds' argument.
reported by: rui rlex <rui.rlex@gmail.com>
semctl.2
Nicolas François
Remove some redundant words
setpgid.2
Michael Kerrisk
Add an explanation of orphaned process groups
splice.2
tee.2
vmsplice.2
Mark Hills
Fix return type
Since glibc 2.7, the return type for these functions
is ssize_t (formerly it was long).
stat.2
Nicolas François
Fix small bug in example program
Since it is a failure, EXIT_FAILURE looks more appropriate
than EXIT_SUCCESS.
umount.2
Michael Kerrisk
glibc only exposes MNT_DETACH and MNT_EXPIRE since version 2.11
See http://sourceware.org/bugzilla/show_bug.cgi?id=10092
exit.3
Michael Kerrisk
Add a pointer to explanation of orphaned process groups in setpgid(2)
fflush.3
Michael Kerrisk
fflush() discards buffered input
ffs.3
Michael Kerrisk
Clarify that ffsl() and ffsll() are GNU extensions
getaddrinfo.3
Michael Kerrisk
Note nonstandard assumed hints.ai_flags value when hints is NULL
When hints is NULL, glibc assumes hints.ai_flags is
AI_V4MAPPED|AI_ADDRCONFIG whereas POSIX says 0.
According to Ulrich Drepper, glibc's behavior is better.
getmntent.3
Mike Frysinger
setmntent() argument is 'filename' not 'fp'
The description of setmntent() formerly used the wrong
argument name.
posix_fallocate.3
Nicolas François
Fix reference to POSIX.1-2008
The sentence mentions twice POSIX.1-2001.
I guess the second one should be POSIX.1-2008.
This should be checked in the standard.
setenv.3
Michael Kerrisk
Improve ERRORS section
Add ENOMEM error; improve EINVAL description. Also, make
RETURN VALUE section a little more accurate in its mention
of errno.
strftime.3
Nicolas François
Fix error in description: s/Monday/Thursday/
proc.5
Nicolas François
Fix page cross reference
max_user_watches is better explained in epoll(7) than inotify(7).
proc.5
Michael Kerrisk
dmesg is in section 1, not section 8
capabilities.7
Michael Kerrisk
FS UID manipulations affect CAP_LINUX_IMMUTABLE and CAP_MKNOD
Nowadays, file system UID manipulations also affect
CAP_LINUX_IMMUTABLE (since 2.6.3) and CAP_MKNOD (since 2.6.29).
capabilities.7
Michael Kerrisk
Fix version number for CAP_MKNOD in FS UID manipulations
A recent patch said "since 2.6.29". It should have
been "since 2.6.30".
capabilities.7
Nicolas François
Reword a bad sentence in description of capability bounding set.
mq_overview.7
Michael Kerrisk
Change documented ranges for msg_max and msgsize_max
Linux 2.6.28 changed the permissible ranges for
these /proc files.
tcp.7
udp.7
Nicolas François
Replace references to syctl interfaces with /proc

Global fix: Consistently define the Epoch
All definitions of the Epoch have been refactored to the following:
1970-01-01 00:00:00 +0000 (UTC)
That form is more consistent, logical, precise, and internationally
recognizable than the other variants.
Also, some wording has been altered as well.

Michael Kerrisk
Update feature test macro requirements
Starting in glibc 2.10, defining _XOPEN_SOURCE >= 700,
or _POSIX_C_SOURCE >= 200809 exposes the declarations of
these functions.
Changes to individual pages
---------------------------
clock_getres.2
Michael Kerrisk
Update text on nonsetabble CLOCK_*_CPUTIME_ID clocks
SUSv3 permits, but does not require CLOCK_THREAD_CPUTIME_ID and
CLOCK_PROCESS_CPUTIME_ID to be settable.
See http://bugzilla.kernel.org/show_bug.cgi?id=11972.
execve.2
Colin Watson
Fix description of treatment of caught signals
Caught signals reset to their default on an execve() (not
to being ignored).
fcntl.2
Michael Kerrisk
s/F_OWNER_GID/F_OWNER_PGRP/
Peter Zijlstra took the name change I suggested.
Michael Kerrisk
Document F_[SG]ETOWN_EX; update details on F_SETOWN
Linux 2.6.32 adds F_SETOWN_EX and F_GETOWN_EX.
Linux 2.6.12 changed (broke) the former behavior of
F_SETOWN with respect to threads.
intro.2
intro.3
Michael Kerrisk
Make subsection heading consistent with other intro.? pages
These pages used "Copyright Terms"; the other intro.? pages
used "Copyright Conditions". Make these pages like the others.
sendfile.2
Michael Kerrisk
Clarify behavior when 'offset' is NULL
seteuid.2
Michael Kerrisk
Note unstandardized behavior for effective ID
POSIX.1 doesn't require that the effective ID can be changed
to the same value it currently has (a no-op). The man page
should note this, since some other implementations
don't permit it.
setgid.2
Michael Kerrisk
Fix EPERM error description
s/effective group ID/real group ID/
This bug lived in man pages for 15 years before Jason
spotted it! I checked back in Linux 1.0, and the behavior
was as the fixed man page describes.
setreuid.2
Michael Kerrisk
Add more detail on POSIX.1 specification for these syscalls
setuid.2
Michael Kerrisk
Remove crufty statement that seteuid() is not in POSIX
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=569812
stime.2
strftime.3
tzset.3
zic.8
Michael Witten
GMT -> UTC (where appropriate)
sync_file_range.2
Christoph Hellwig
Add some big warnings re data integrity
This system call is by design completely unsuitable for any data
integrity operations. Make that very clear in the manpage.
CPU_SET.3
Vlastimil Babka
SYNOPSIS: Fix return types for CPU_COUNT_*()
These functions return 'int' not void'.
confstr.3
Michael Kerrisk
Fix feature test macro requirements
daemon.3
Michael Kerrisk
Fix description of 'nochdir' argument.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=554819
gethostbyname.3
Michael Kerrisk
Document feature test macro requirements for herror() and hstrerror()
Since glibc 2.8, one of _BSD_SOURCE, _SVID_SOURCE,
or _GNU_SOURCE is required.
getline.3
Michael Kerrisk
Update to reflect that these functions were standardized in POSIX.1-2008
getnameinfo.3
Michael Kerrisk
Document feature test macros requirements for NI_MAXHOST and NI_MAXSERV
Since glibc 2.8, one of _BSD_SOURCE, _SVID_SOURCE, or _GNU_SOURCE
must be defined to obtain these definitions.
getopt.3
Jonathan Nieder
Fix feature test macro requirements
memchr.3
Michael Kerrisk
Add feature text macro requirements for memrchr()
nextafter.3
Michael Kerrisk
Fix notable error in DESCRIPTION.
"less than y" should be "less than x".
popen.3
Michael Kerrisk
Fix feature test macro requirements
pthread_attr_setdetachstate.3
pthread_attr_setschedparam.3
pthread_attr_setschedpolicy.3
Denis Barbier
Argument name is 'attr' not 'thread'
The function argument was misnamed in the DESCRIPTION on these
three pages.
rtnetlink.3
Michael Kerrisk
Various fixes in example code
Edward reported a problem in the example code, where a variable
seems to be misnamed. Upon inspection, there seem to be a few
such instances, and this patch is my best guess at how things
should look.
sched_getcpu.3
Michael Kerrisk
Place correct header file in SYNOPSIS
sleep.3
Bill O. Gallmeister
sleep() puts calling *thread* to sleep (not calling *process*)
sleep.3
Bill O. Gallmeister
Add nanosleep(2) to SEE ALSO
strftime.3
Michael Kerrisk
%z is defined in SUSv3
So, substitute "GNU" tag in man page by "SU".
strftime.3
Michael Witten
Move 822-compliant date format example to EXAMPLES section
The RFC 822-compliant date format given in the description
of `%z' is now moved to the `EXAMPLES' section (note: `EXAMPLE'
has been renamed `EXAMPLES').
Furthermore, that format example is now actually
RFC 822-compliant (using `%y' instead of `%Y') and has been
qualified as being correct only when in the context of at least
an English locale. Also, `%T' is used in place of `%H:%M:%S'.
For completeness, an RFC 2822-compliant format example has been
similarly added.
strftime.3
Michael Witten
Expand introductory text
strftime.3
Michael Witten
Clarification of %z specifier
string.3
Mark Hills
Add stpcpy() to this list of string functions
strptime.3
Michael Kerrisk
Initialize tm structure in example program

Michael Kerrisk
Remove pages now documented
By now, the following are documented:
fopencookie(3)
freeifaddrs(3)
rawmemchr(3)
readdir_r(3)
getutmp(3)
getutmpx(3)
utmpxname(3)
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=554819
group.5
Michael Kerrisk
s/passwd/password/
The page inconsistently used "passwd" and "password"
to refer to the same field.
capabilities.7
Michael Kerrisk
Update securebits discussion to use SECBIT_* flags
feature_test_macros.7
Michael Kerrisk
_POSIX_C_SOURCE >= 200808 defines _ATFILE_SOURCE
Since glibc 2.10, _POSIX_C_SOURCE >= 200808 defines _ATFILE_SOURCE
path_resolution.7
Michael Kerrisk
Add readlink(2) to SEE ALSO
Michael Kerrisk
Fix NAME line
The poorly constructed part preceding "\-" causes apropos
not to be able to find the subject.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=558300
signal.7
Michael Kerrisk
Fix discussion of SIGUNUSED
Clarify that this signal really is synonymous with SIGSYS.

Major updates
Update the page to consolidate information from the
outdated man-pages quotactl.2 page and the quotactl.2

Changes to individual pages
---------------------------
fcntl.2
Michael Kerrisk
Note that glibc 2.11 papers over the kernel F_GETOWN bug
Since version 2.11, glibc works around the kernel limitation for
process groups IDs < 4096 by implementing F_GETOWN via F_GETOWN_EX.
futex.2
Michael Kerrisk
Various fixes in SEE ALSO
getpriority.2
nice.2
Francesco Cosoleto
Move renice from section 8 to section 1
getrusage.2

Enhanced description of various fields
mlock.2
Michael Kerrisk
/proc/PID/status VmLck shows how much memory a process has locked
After a note from Tom Swigg, it seems sensible mention VmLck here.
mount.2
Petr Uzel
Fix incorrect path
move_pages.2
Andi Kleen
Clarify includes/libraries
mremap.2
Michael Kerrisk
Clarify existence of fifth argument.
msgctl.2

Michael Kerrisk
Bring system call list up to date with Linux 2.6.33
Michael Kerrisk
Fix kernel version number for utimes()
cproj.3
Michael Kerrisk
Note fix for C99 conformance in glibc 2.12.
crypt.3
Petr Baudis
Correct note on key portion significance
As Marcel Moreaux notes:
The Linux manpage for crypt()[1] contains the following
statement as the last sentence of the NOTES section:
In the SHA implementation the entire key is significant
(instead of only the first 8 bytes in MD5).
It should probably say "DES" where it says "MD5" (and maybe
"MD5/SHA" where it says "SHA"), because in MD5 password hashing,
the entire key is significant, not just the first 8 bytes.
This patch fixes the wording.
fmemopen.3
Michael Kerrisk
Bug fix in example program
ftw.3
Michael Kerrisk
Note that if 'fn' changes CWD, the results are undefined
Michael Kerrisk
Clarify description of fpath argument
As reported by Pierre Habouzit, 'fpath' is not relative
to 'dirpath'. It is either relative to the calling process's
current working directory (if 'dirpath' was relative), or it
is absolute (if 'dirpath' was absolute).
getaddrinfo.3
Christian Franke
Fix a field name mixup: s/ai_family/ai_flags/
getline.3
Robert Wohlrab
Remove unneeded check before free()
The manpage of getline shows an example with an extra NULL pointer
check before it calls free. This is unneeded according to free(3):
If ptr is NULL, no operation is performed.
This patch removes the "if" check.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572508
log.3
log10.3
log2.3
Jan Engelhardt
Add cross-references to other-base logarithmic functions
opendir.3
Petr Baudis
Specify feature test macro requirements for fdopendir(3)
Currently, there is no note on the fact that fdopendir() is
POSIX.2008-only.
openpty.3
Eric Blake
Use const as appropriate
Michael Kerrisk
Note glibc version that added "const" to function arguments
Michael Kerrisk
Explicitly note that these functions are not in POSIX
resolver.3
Michael Kerrisk
Fix declaration of dn_comp() in SYNOPSIS
Remove the second 'exp_dn' from the calling signature.
termios.3
Michael Kerrisk
Change NOFLSH text to speak of characters, not signals
core.5
Michael Kerrisk
Update description of coredump_filter
Kernel 2.6.24 added MMF_DUMP_ELF_HEADERS.
Kernel 2.6.28 added MMF_DUMP_HUGETLB_PRIVATE and
MMF_DUMP_HUGETLB_SHARED.
elf.5
Daisuke HATAYAMA
Document PN_XNUM extension
In linux-2.6.34-rc1, an ELF core extension was added; user-land
tools manipulating ELF core dump such as gdb and binutils has
already been modified before; so elf.5 needs to be modified
accordingly.

Michael Kerrisk
Remove EI_BRAND
As reported by Yuri Kozlov and confirmed by Mike Frysinger,
EI_BRAND is not in GABI
(http://www.sco.com/developers/gabi/latest/ch4.eheader.html)
It looks to be a BSDism
Michael Kerrisk
Remove words under '.note': "described below"
The existing text is broken, because there is
no '"Note Section" format' describe below. Simplest
solution is to remove the words "described below".
filesystems.5
Jeff Barry
Add discussion of ntfs and ext4
proc.5
Michael Kerrisk
Simplify description of /proc/sys and /proc/sys/fs
In the description of these directories, there's no need
to list all the files and subdirectories that they contain;
that information is provided by the entries that follow.
services.5
Yuri Kozlov
Remove crufty reference to nonexistent BUGS section
capabilities.7
Michael Kerrisk
Document CAP_SYS_RESOURCE and F_SETPIPE_SZ
With CAP_SYS_RESOURCE, a process can increase pipe capacity above
/proc/sys/ps/pipe-max-size.
Michael Kerrisk
Add get_robust_list() info under CAP_SYS_PTRACE
Michael Kerrisk
Add MADV_HWPOISON under CAP_SYS_ADMIN
signal.7
Michael Kerrisk
Make a clearer statement about nonportable aspect of signal(2)
Make a clearer statement that signal(2) is less portable for
establishing a signal handler.
socket.7
Michael Kerrisk
Use consistent language to describe read-only socket options
udp.7
Michael Kerrisk
Add FIONREAD warning.
Warn that FIONREAD can't can't distinguish case of a zero-length
datagram from the case where no datagrams are available.

(It's an open question whether or not a version of tzfile.5
should live independently in man-pages. It was added to the
man-pages set many years ago. For now, I'll follow a
conservative course that causes least pain to downstream,
by continuing to maintain a separate copy in man-pages.)

SYNOPSIS: Add reference to feature_test_macros(7)
These pages specify feature test macros in the function
prototypes. Add a reference to feature_test_macros(7),
so that readers are pointed to the information that
feature test macros must be defined before including
*any* header file.

Note that feature test macros must be defined before *any* includes
Programmers often make the mistake of including a feature test
macro only after having already included some header files.
This patch adds some text at opportune places to remind
programmers to do things the right way.

As described in commit edd5cd4a9424f22b0fa08bef5e299d41befd5622,
the sync_file_range() argument order is broken for some
architectures (PowerPC, ARM, tile). The remedy was a different
system call using the right argument order on those architectures.
psignal.3

Document psiginfo()
psiginfo() was added to glibc in version 2.10.

Fix description of abstract socket names
As reported by Lennart Poettering:
The part about "abstract" sockets is misleading as it suggests
that the sockaddr returned by getsockname() would necessarily
have the size of sizeof(struct sockaddr), which however is not
the case: getsockname() returns exactly the sockaddr size that
was passed in on bind(). In particular, two sockets that are
bound to the same sockaddr but different sizes are completely
independent.
See https://bugzilla.kernel.org/show_bug.cgi?id=19812
Michael Kerrisk
Fix description of "pathname" sockets
As reported by Lennart Poettering:
The part about "pathname" sockets suggests usage of
sizeof(sa_family_t) + strlen(sun_path) + 1
for calculating the sockaddr size. Due to alignment/padding
this is probably not a good idea. Instead, one should use
offsetof(struct sockaddr_un, sun_path) + strlen() + 1
or something like that.

kexec_load.2
Andi Kleen
New page documenting kexec_load(2)
Michael Kerrisk
Add license
Michael Kerrisk
Incorporate fixes from Eric W. Biederman
Eric noted that a few instances of "virtual" should
be "physical" and noted:
There is an expectation that at hand off from sys_kexec that
virtual and physical addresses will be identity mapped. But
this isn't the old Alpha booting convention where you have
a virtual address and then you have to parse the page table
to figure out where your kernel was actually loaded.
Michael Kerrisk
Additions and edits by mtk
Various wording and layout improvements.
Fixed the name of a constant: s/KEXEC_ARCH_I386/KEXEC_ARCH_386/.
Added RETURN VALUE and ERRORS sections.

Removed details of using syscall; the reader can find them in
syscall(2).

Comparing to koi8-u.7, I noticed some inconsistencies in special
character names. After checking with the following Unicode related
pages, please find inline (and gzipped attached, hopefully not
messing with encoding), a patch in order to make it right, on an
Unicode point of view.

http://www.unicode.org/charts/PDF/U25A0.pdf
http://www.unicode.org/charts/PDF/U0080.pdf
http://www.unicode.org/charts/PDF/U1D400.pdf
David Prevot
Fix SEE ALSO reference and letter names
The koi8-r(7) (Russian Net Character Set) manual page refers
to iso-8859-7(7) manual page, which is the Latin/Greek one.
I guess it should refer instead to the iso-8859-5(7)
(Latin/Cyrillic) one. This is addressed at the end of the patch.
It has also been spotted that letter names are different in
this manual page and in the Unicode related page [0], the
first part of the page address this.
0: http://www.unicode.org/charts/PDF/U0400.pdf
man-pages.7
Michael Kerrisk
Update example
The old example used the chmod(2) man page, but the
feature test macro requirements on that page had changed.
Update to use an example from a different page (acct(2),
whose feature test macro requirements are probably unlikely
to change in the future).

crypt.3
Michael Kerrisk [Jan Engelhardt]
Fix header file and feature test macro requirements for crypt_r()
err.3
Seonghun Lim
Clean up description of error message source
In the second paragraph of DESCRIPTION section, one of the
sources of error messages is incorrect: the four functions obtain
error message only from errno, and "a code" is just relevant
with errc() and warnc(), which are not present on Linux.
see http://www.unix.com/man-page/freebsd/3/ERR/ .
Then, the third paragraph becomes a duplicate.

Regid Ichira
Fix wording error
See http://bugs.debian.org/cgi-bin/bugreport.cgi?614021

Seonghun Lim
Update ERRORS section

ERRORS: EBADF can also occur for nonwritable file descriptor
As noted in the DESCRIPTION, the file descriptor must be writable
in order to place a lock.

Reorder prototypes in SYNOPSIS
calloc() comes before realloc() in the other sections,
so should do in SYNOPSIS, too.

SEE ALSO: add reference to wcstombs(3)
memcmp.3
Michael Kerrisk [Sebastian Unger]
Clarify that comparison interprets bytes as "unsigned char"

---------------------------------------------
fallocate.2
Lucian Adrian Grijincu
Document FALLOC_FL_PUNCH_HOLE
FALLOC_FL_PUNCH_HOLE was added in Linux 2.6.38,
for punching holes in the allocated space in a file.
Changes to individual pages
---------------------------
dup.2
Michael Kerrisk
SYNOPSIS: Add "#include <fcntl.h>" for O_* constants
fallocate.2
Michael Kerrisk
Substantial restructuring of DESCRIPTION
The addition of a second class of operation ("hole punching")
to the man page made it clear that some significant restructuring
is required. So I substantially reworked the page, including the
preexisting material on the default "file allocation" operation.
Michael Kerrisk [Josef Bacik]
Add further details for FALLOC_FL_PUNCH_HOLE
Michael Kerrisk
ERRORS: Add EPERM error case for FALLOC_FL_PUNCH_HOLE
fork.2
Michael Kerrisk
NOTES: Describe clone() call equivalent to fork()
fsync.2
Christoph Hellwig
Various improvements
- explain the situation with disk caches better
- remove the duplicate fdatasync() explanation in the NOTES
section
- remove an incorrect note about fsync() generally requiring two
writes
- remove an obsolete ext2 example note
- fsync() works on any file descriptor (doesn't need to be
writable); correct the EBADF error code explanation
Michael Kerrisk [Guillem Jover]
Note that some systems require a writable file descriptor
An edited version of Guillem Jover's comments:
[While the file descriptor does not need to be writable on Linux]
that's not a safe portable assumption to make on POSIX in general
as that behavior is not specified and as such is
implementation-specific. Some Unix systems do actually fail on
read-only file descriptors, for example [HP-UX and AIX].
mount.2
Michael Kerrisk [Junjiro Okajima]
Removed erroneous statement about MS_RDONLY and bind mounts
open.2
Jessica McKellar
Fix grammar in O_DIRECT description
Some small grammar fixes to the O_DIRECT description.
pipe.2

PROTOTYPE: Fix return type of syncfs()
vfork.2
Michael Kerrisk [starlight@binnacle.cx]
Clarify what is duplicated in the child
Add some words to make it clear to the reader that vfork(),
like fork(), creates duplicates of process attributes
in the child.
Michael Kerrisk
Note clone() flags equivalent to vfork()
Michael Kerrisk [starlight@binnacle.cx, Mike Frysinger]
Add some notes on reasons why vfork() still exists
Michael Kerrisk [starlight@binnacle.cx]
Clarify that calling *thread* is suspended during vfork()
Michael Kerrisk
CONFORMING TO: Note that POSIX.1-2001 marked vfork() obsolete

Michael Kerrisk
Document _ISOC11_SOURCE
inotify.7
Michael Kerrisk [Yang Yang]
Note that 'cookie' field is set to zero when unused
man.7
Michael Kerrisk
Various fixes for description of NAME section
As noted by reporter:
* The code sample given for the NAME section is incomplete because
the actual content sample is not given.
* Additionally, the description assumes that the item described is
a command, which need not be the case.
* The command makewhatis is not present on my system; the
documented tool to create the whatis database is called mandb.
* The description on .SH NAME in man(7) should either copy the
relevant paragraph of lexgrog(1) or refer to it.

bdflush.2
Michael Kerrisk
Note that bdflush() is deprecated, and does nothing
nfsservctl.2
Michael Kerrisk
Note that this system call was removed in Linux 3.1
ptrace.2
Denys Vlasenko [Oleg Nesterov, Tejun Heo]
add extended description of various ptrace quirks
Changes include:
s/parent/tracer/g, s/child/tracee/g - ptrace interface now
is sufficiently cleaned up to not treat tracing process
as parent.
Deleted several outright false statements:
- pid 1 can be traced
- tracer is not shown as parent in ps output
- PTRACE_ATTACH is not "the same behavior as if tracee had done
a PTRACE_TRACEME": PTRACE_ATTACH delivers a SIGSTOP.
- SIGSTOP _can_ be injected.
- Removed mentions of SunOS and Solaris as irrelevant.
- Added a few more known bugs.
Added a large block of text in DESCRIPTION which doesn't focus
on mechanical description of each flag and operation, but rather
tries to describe a bigger picture. The targeted audience is
a person which is reasonably knowledgeable in Unix but did not
spend years working with ptrace, and thus may be unaware of its
quirks. This text went through several iterations of review by
Oleg Nesterov and Tejun Heo.
This block of text intentionally uses as little markup as possible,
otherwise future modifications to it will be very hard to make.
Michael Kerrisk
Global clean-up of page
* Wording and formatting fixes to existing text and
Denys Vlasenko's new text.
* Various technical amendments and improvements to
Denys Vlasenko's new text.
* Added FIXME for various problems with the current text.

New and rewritten pages
-----------------------
malloc_trim.3
Michael Kerrisk
New man page for malloc_trim(3)
malloc_usable_size.3
Michael Kerrisk
New man page for malloc_usable_size(3)
Newly documented interfaces in existing pages
---------------------------------------------
prctl.2
Cyrill Gorcunov
Document PR_SET_MM (new in Linux 3.3)
Michael Kerrisk
Various edits and improvements to Cyrill's patch
Changes to individual pages
---------------------------
epoll_create.2
Michael Kerrisk
Rework discussion of 'size' argument
Michael Kerrisk
Add .SS for description of epoll_create1()
epoll_wait.2
Michael Kerrisk [Armin Rigo]
Another thread can add to epoll instance while epoll_wait is blocked
See https://bugzilla.kernel.org/show_bug.cgi?id=43072
Michael Kerrisk
Clarify that epoll_pwait() blocks calling *thread*
A few wording improvements
fchmodat.2
Michael Kerrisk [Mike Frysinger]
Note difference between glibc wrapper and underlying system call
The wrapper function has a 'flags' argument (which currently
serves no purpose), while the underlying system call does not.
fcntl.2
Abhijith Das
Explain behaviour of F_GETLEASE during lease break
Michael Kerrisk [Eric Blake]
Change type of arg from "long" to "int"
Various fcntl(2) commands require an integral 'arg'.
The man page said it must be "long" in all such cases.
However, for the cases covered by POSIX, there is an
explicit requirement that these arguments be "int".
Update the man page to reflect. Probably, all of the
other "long" cases (not specified in POSIX) should
be "int", and this patch makes them so. Based on a
note fromEric Blake, relating to F_DUPFD_CLOEXEC.
gettimeofday.2
Michael Kerrisk
Reorganize content
The main change is to move the historical information about
the 'tz_dsttime' to NOTES.
Michael Kerrisk [Felix]
Note that compiler issues warnings if 'tv' is NULL
mmap.2
Michael Kerrisk [Kevin O'Gorman]
Clarify that this system call should not be invoked directly
See https://bugzilla.kernel.org/show_bug.cgi?id=42892
Michael Kerrisk
Clarify NOTES discussion of mmap() versus mmap2()
poll.2
Michael Kerrisk [Michael Welsh Duggan]
Document negative value in 'fd' field
Michael Kerrisk
Document semantics of passing zero in 'events' field
ptrace.2
Denys Vlasenko
Various fixes
For some reason, the PTRACE_TRACEME paragraph talks about some
general aspects of ptraced process behavior. It repeats the
"tracee stops on every signal" information even though that was
already explained just a few paragraphs before. Then it describes
legacy SIGTRAP on execve().
This patch deletes the first part, and moves the second part up,
into the general ptrace description. It also adds
"If PTRACE_O_TRACEEXEC option is not in effect" to the description
of the legacy SIGTRAP on execve().
The patch also amends the part which says "For requests other
than PTRACE_KILL, the tracee must be stopped." - PTRACE_ATTACH
also doesn't require that.
sigaction.2
Michael Kerrisk [Andreas Jaeger, ]
Clarify that the use of SI_SIGIO is for Linux 2.2 only
See also http://sourceware.org/bugzilla/show_bug.cgi?id=6745
sigprocmask.2

Remove mention of terminating null in description of rawmemchr()
perror.3
Michael Kerrisk [Jesus Otero]
Note that use of 'sys_errlist' is deprecated
rcmd.3
Michael Kerrisk
glibc eventually added a declaration of iruserok() in version 2.12
sysconf.3
Michael Kerrisk [Ricardo Catalinas Jiménez]
Add mention of _SC_SYMLOOP_MAX
nologin.5
Michael Kerrisk [Tetsuo Handa]
nologin must not only exist, but *be readable* to be effective
nsswitch.conf.5
Mark R Bannister
Significant rewrites and improvements
This patch applies to nsswitch.conf.5 in man-pages-3.36.
My changes almost completely rewrite large sections of the
man page. They are needed to add clarity, correct grammar,
reduce confusion, and bring up-to-date with the latest glibc.
I have checked the man page against the nss source code in
glibc 2.14.90.
Historical notes are demoted to the footer.
The rewrite makes the man page much clearer to
understand, more authoratitive, and easier to read.
Michael Kerrisk
Light edits to Mark Bannister's changes
capabilities.7
Michael Kerrisk
Add prctl(PR_SET_MM) to CAP_SYS_RESOURCE
epoll.7
Michael Kerrisk
Some minor clarifications at start of DESCRIPTION

Note interactions of these two clocks with discontinuous
adjustments to the system time and NTP/adjtime(2).
fallocate.2
Michael Kerrisk [John Sullivan]
Fix description of ENOSYS and EOPNOTSUP errors
As reported in https://bugzilla.redhat.com/show_bug.cgi?id=680214

Add some basic documentation of these operations, with a pointer to
tools/perf/design.txt for more information.
Michael Kerrisk [Marcel Holtmann]
Amend details of PR_SET_PDEATHSIG
ptrace.2
Michael Kerrisk [Mike Frysinger]
Note SPARC deviation with respect to get/set regs
SPARC reverses the use of 'addr' and 'data' for
PTRACE_GETREGS, PTRACE_GETFPREGS, PTRACE_SETREGS,
and PTRACE_SETFPREGS.
send.2
Stefan Puiu
Document EACCES error case for UDP
sigaction.2
Michael Kerrisk
Remove mention of raise(3) for SI_USER
For a long time now, glibc's raise(3) didn't yield SI_USER
for the signal receiver, so remove mention of raise(3)
here. The user can deduce the details, if needed, by looking
at the recently updated raise(3) page.
aio_cancel.3
Michael Kerrisk [Jon Grant]
Rewrite RETURN VALUE section to be clearer
aio_init.3
Michael Kerrisk [Jon Grant]
Remove extraneous "POSIX" from NAME section
btree.3

hash.3
mpool.3
recno.3
Michael Kerrisk [Brian M. Carlson]
Note that glibc no longer provides these interfaces
glibc stopped providing these interfaces with v2.2.
Nowadays, the user that finds these pages probably wants
the libdb API, so note this in the page.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=337581
fopen.3
Michael Kerrisk
BUGS: Note limitation on number of flag characters parsed in 'mode'
Michael Kerrisk
Note that 'c' and 'e' flags are ignored for fdopen()
Determined from reading libio/iofdopen.c.
Michael Kerrisk
Document ",ccs=string" feature of 'mode' for fopen()/freopen()
getgrnam.3
Michael Kerrisk [Ulrich Drepper]
Fix discussion of _SC_GETGR_R_SIZE_MAX
The value is not meant to be a maximum (as was specified in
SUSv3) but an initial guess at the required size
(as specified in SUSv4).
getpwnam.3
Michael Kerrisk [Ulrich Drepper]
Fix discussion of _SC_GETPW_R_SIZE_MAX
The value is not meant to be a maximum (as was specified in
SUSv3) but an initial guess at the required size
(as specified in SUSv4).
malloc.3
mallopt.3
mtrace.3
Michael Kerrisk
SEE ALSO: add mcheck(3)
memchr.3
Michael Kerrisk
Clarify description, omitting mention of "strings" and "characters"
The existing text slipped into talking about characters and
strings, which could mislead readers into thing that, for
example, searches for the byte '\0' are treated specially.
Therefore, rewrite in terms of "bytes" and "memory areas".
At the same time, make a few source file clean-ups.
mkstemp.3
Michael Kerrisk
Add "mkstemps" and "mkostemps" to NAME line
posix_openpt.3
Michael Kerrisk [Vadim Mikhailov]
Add some details on use of the slave pathname
An explicit pointer to ptsname(3) is useful, as is a note
of the fact that the slave device pathname exists only as
long as the master device is held open.
raise.3
Michael Kerrisk
Add some notes on underlying system call that is used
rcmd.3
Michael Kerrisk
Add some details of the rresvport() 'port' argument
resolver.3
Petr Baudis
Note that many options are documented in resolv.conf(5)
scandir.3
Michael Kerrisk [Daniel J Blueman]
Improve EXAMPLE source code: s/0/NULL/ in scandir() call
strchr.3
James Hunt
Explain behavior when searching for '\0'
strerror.3
Eric Blake [Stefan Puiu]
Improve strerror_r() description
POSIX requires that perror() not modify the static storage
returned by strerror(). POSIX 2008 and C99 both require that
strerror() never return NULL (a strerror() that always
returns "" for all inputs is valid for C99, but not for POSIX).
http://sourceware.org/bugzilla/show_bug.cgi?id=12204
documents glibc's change to come into compliance with POSIX
regarding strerror_r() return value. The GNU strerror_r() use
of 'buf' was confusing - I ended up writing a test program that
proves that 'buf' is unused for valid 'errnum', but contains
truncated "unknown message" for out-of-range 'errnum'.
See also http://austingroupbugs.net/view.php?id=382
Bernhard Walle
Correct description of error return for XSI strerror_r()
Michael Kerrisk [Eric Blake]
Note how to use 'errno' to detect errors when calling strerror()
Michael Kerrisk [Jon Grant]
Add an example of the kind of string returned by strerror()
resolv.conf.5
Petr Baudis
Document "single-request" option
inotify.7
Michael Kerrisk
Note buffer size that guarantees being able to read at least one event
James Hunt
Correct description of size of inotify_event structure
iso_8859-1.7
Eugen Dedu
Add "-" for SOFT HYPHEN
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=156154
netdevice.7
Brian F. G. Bidulock
Document some SIOC configuration ioctls
This patch adds common but missing SIOC configuration ioctls to
the netdevice.7 manual pages that are not documented anywhere
else. SIOCSIFPFLAGS and SIOCGIFPFLAGS are linux-specific. Flag
values come from Linux 2.6.25 kernel headers for sockios. The
others are standard BSD ioctls that have always been implemented
by Linux and were verified from inspecting netdevice.c kernel
code.
socket.7
Michael Kerrisk [Alexey Toptygin]
Correct description of SO_BROADCAST
tcp.7
lepton
Correct description for TCP_MAXSEG on modern kernel

Clarify that these functions operate on bytes, not (wide) characters
Change 'character(s)' to 'byte(s)' to make clear that these
functions operate on bytes, not wide / UTF8 characters.
(POSIX uses 'byte(s)' similarly, to make this point.)
icmp.7

packet.7
raw.7
rtnetlink.7
unix.7
x25.7
Michael Kerrisk
Remove names of constants from NAME line
Some of the sockets/network protocol pages included names of
the corresponding address family constants in the NAME line,
but this wasn't done consistently across all pages, and probably
it adds little value in those pages that did do this. So, remove
these constants from those pages that have them in the NAME
section.
Changes to individual pages
---------------------------
clock_getres.2
Michael Kerrisk [Josh Triplett]
Expand description of CLOCK_REALTIME
Make it clear that this clock may be discontinuous, and is

Note details of POSIX.1-2008 specification of 'b' in 'mode'
Michael Kerrisk [Rich Felker]
BUGS: fmemopen() doesn't correctly set file position in some cases
If 'mode' is append, but 'size' does not cover a null byte
in 'buf', then fmemopen() incorrectly sets the initial file
position to -1, rather than the next byte after the end of
the buffer.
See http://sourceware.org/bugzilla/show_bug.cgi?id=13151
Michael Kerrisk
BUGS: fmemopen() incorrectly handles size==0 case
If size is zero, fmemopen() fails, This is surprising behavior,
and not specified in POSIX.1-2008.

BUGS: Note silent ABI change for fmemopen() in glibc 2.9
Michael Kerrisk [Rich Felker]
BUGS: Append mode does not force writes to append
Append mode correctly sets the initial offset but does
not force subsequent writes to append at end of stream.
See http://sourceware.org/bugzilla/show_bug.cgi?id=13152
Michael Kerrisk [Eric Blake]
BUGS: Note inconsistent treatment of 'b' in 'mode'
fopen() permits, for example, both "w+b" and "wb+",
but only the latter is meaningful to fmemopen().

utf-8.7
Brian M. Carlson
Two clarifications
This patch clarifies that 0xc0 and 0xc1 are not valid in any UTF-8
encoding[0], and it also references RFC 3629 instead of RFC 2279.
[0] In order to have 0xc0, you'd have to have a two-byte encoding
with all the data bits zero in the first byte (and thus only six
bits of data), which would be an ASCII character encoded in the
non-shortest form. Similarly with 0xc1.

Sami Kerola
Global fix: use UR macro where applicable
The syntax .UR http://example.com paired with .UE will create
links which one can interact, if the pager allows that. One
way to see the effect is ask the man(1) command to use browser
display, e.g.:
man -H man7/uri.7
("\:" is optional groff syntax to permit hyphenless line breaks.)

mprotect.2
Michael Kerrisk [Rasmus Villemoes]
'addr' argument is not const
As reported by Rasmus:
Both my system's man-pages (3.22) and the latest online
(3.41) show:
int mprotect(const void *addr, size_t len, int prot);
as the prototype for mprotect(2). However, POSIX [1] and the
actual sys/mman.h (on all the systems I checked) do not have
the const qualifier on the first argument.

svipc.7
Michael Kerrisk
Don't mention that ipc_perm is defined in <sys/ipc.h>
There's no need to mention that the 'ipc_perm' structure
is defined in <sys/ipc.h>. That's an implementation detail,
and furthermore <sys/ipc.h> is itself included by the other
System V IPC header files. The current text might lead the
reader to conclude that they must include <sys/ipc.h>, which
is not the case (it is required neither on Linux, nor by the
standards).

Add text to NOTES to say that the <sys/types.h> and <sys/ipc.h>
header files aren't required by Linux or the standards, but may
be needed for portability to old systems.
ptrace.2
Denys Vlasenko
Explain WNOHANG behavior and EINTR bug
I didn't like the "SIGKILL operates similarly, with exceptions"
phrase (if it's different, then it's not "similar", right?),
and now I got around to changing it. Now it says simply:
"SIGKILL does not generate signal-delivery-stop and therefore
the tracer can't suppress it."
Replaced "why WNOHANG is not reliable" example with a more
realistic one (the one which actually inspired to add this
information to man page in the first place): we got
ESRCH - process is gone! - but waitpid(WNOHANG) can still
confusingly return 0 "no processes to wait for".
Replaced "This means that unneeded trailing arguments may
be omitted" part with a much better recommendation
to never do that and to supply zero arguments instead.
(The part about "undocumentedness" of gcc behavior was bogus,
btw - deleted).
Expanded BUGS section with the explanation and an example
of visible strace behavior on the buggy syscalls which
exit with EINTR on ptrace attach. I hope this will lead
to people submitting better bug reports to lkml about
such syscalls.

iso_8859-1.7
Bjarni Ingi Gislason
Explanation of SOFT HYPHEN and the code for it
<groff: iso_8859-2.7>:89: warning: can't find special character `shc'
This is the only "iso_8859-*.7" file that has this (now)
undefined character. The code in column four in "iso_8859-1.7" is
"0x2D" ("HYPHEN, MINUS SIGN" or "HYPHEN-MINUS") instead of "0xAD".
See Debian bug 156154 (or package "manpages").
There should be an explanation for this graphic character and the
code should be 0xAD in iso_8859-1.7 (as in all others), even
though "[gn]roff" does not display a "HYPHEN" in that position of
the table.
The line with "SOFT HYPHEN" gets a footnote and a short
explanation.
mdoc.7
Bjarni Ingi Gislason
Fixing a warning and a table
Fis warning from "groff -ww ..." (or "man --warnings=w ..."):
<groff: mdoc.7>:294: warning:

In one table the distance between columns is too small in the
"ps" output. (Bug in the groff "doc.tmac" macro?)
mdoc.samples.7
Bjarni Ingi Gislason

tab character in unquoted macro argument
[+3 similar warnings]
<standard input>:813: warning: macro `Pu' not defined
Usage: .Rv -std in sections 2 and 3 only (#1669)
mdoc warning: A .Bl directive has no matching .El (#1821)
String "Pu" defined as a row of punctuation characters.

Some arguments, that start with a period or are the name of a
macro, protected with "\&".
Variable name for macro ".Rv" corrected.

Changes to individual pages
---------------------------
epoll_wait.2
Michael Kerrisk [Fredrik Arnerup]
Describe timeout limitation in kernels < 2.6.37
As reported by Fredrik (and as far as I can tell the problem
went back to 2.6.0):
The timeout argument has an upper limit. Any values above that
limit are treated the same as -1, i.e. to wait indefinitely.
The limit is given by:
#define EP_MAX_MSTIMEO min(1000ULL * MAX_SCHEDULE_TIMEOUT / HZ, \
(LONG_MAX - 999ULL) / HZ)
That is, the limit depends on the size of a long and the timer
frequency. Assuming the a long is never smaller than 32 bits
and HZ never larger than 1000, the worst case is 35 minutes.
I think this should be mentioned under "BUGS".
Although this is likely to be fixed in the future
(http://lkml.org/lkml/2010/8/8/144), the problem exists in
at least 2.6.14 - 2.6.35. I don't know if select(2) and poll(2)
are affected.

Note behavior if monitored file descriptor is closed in another thread
Executive summary: a sane application can't rely on any
particular behavior if another thread closes a file descriptor
being monitored by select().
See https://bugzilla.kernel.org/show_bug.cgi?id=40852
Michael Kerrisk

semop() blocks the calling thread, not the process.

pthread_kill.3
pthread_sigqueue.3
Michael Kerrisk
Remove wording "another"
Writing "another thread" in these pages implies that these
functions can't be used to send a signal to the calling thread
itself, which is of course untrue.
sigvec.3
Michael Kerrisk
Add "int" arg to sv_handler definition in sigvec structure
Michael Kerrisk
Fix small error in discussion of blocking of signals
The signal that causes the handler to be invoked is blocked,
but saying "by default" implies that this can be changed via
the API. It cannot. (One needs sigaction(2) for that.)
syslog.3
Simon Josefsson
Remove (apparently bogus) text claiming LOG_AUTH is deprecated
LOG_AUTH is in POSIX, and widely available. There
seems to be no basis to the claim it is deprecated.
Quoting Simon:
I cannot find any other source that claim LOG_AUTH is
deprecated in any way. LOG_AUTH is distinct from
LOG_AUTHPRIV. The GNU C Library manual only documents
LOG_AUTH. The header files contains both without any
comment. Common systems like Debian appear to refer to
both auth and authpriv facilities in syslog configurations.
Popular daemons appear to use both facilities.
Both facilities are discussed in several RFCs.

-----------------------
delete_module.2
Michael Kerrisk
Rewrite to Linux 2.6+ reality
Michael Kerrisk
Change license and copyright
There is now nothing left of the original FSF-copyrighted
page. So, change the copyright and license.
Michael Kerrisk [Lucas De Marchi, Rusty Russell]
Substantial reorganization after comments from Rusty Russell
Rusty notes that O_NONBLOCK is almost always used in
practice. Therefore, it would be better to reorganize
the page to consider that "the default".
init_module.2
Michael Kerrisk
Rewrite to Linux 2.6+ reality
Michael Kerrisk
Change copyright and license
Little of the original page now remains. Change
copyright and license

Global changes
--------------
Various pages
Michael Kerrisk
Global fix: Use consistent capitalization in NAME section
The line(s) in the NAME section should only use capitals
where English usage dictates that. Otherwise, use
lowercase throughout.
Various pages
Michael Kerrisk
Global fix: "userspace" ==> "user space" or "user-space"
Existing pages variously use "userspace or "user space".
But, "userspace" is not quite an English word.
So change "userspace" to "user space" or, when used
attributively, "user-space".

Michael Kerrisk
Default for /proc/sys/fs/protected_{hardlinks,symlinks} is now 0
The default setting of 1 in/proc/sys/fs/protected_hardlinks
and /proc/sys/fs/protected_symlinks caused one too many
breakages for Linus's taste, so commit 561ec64ae67e changed
the default for both files to 0.
Note system call error yielded by /proc/sys/fs/protected_symlinks
Note that violating 'protected_symlinks' restrictions
causes system calls to fail with the error EACCES.

clone.2
Michael Kerrisk
Since 2.6.30, CLONE_NEWIPC also supports POSIX message queues
delete_module.2
Michael Kerrisk
Small rewording of description of effect of O_TRUNC
getrlimit.2
Michael Kerrisk [Trevor Woerner]
Document Linux's nonstandard treatment or RLIMIT_CPU soft limit
Upon encountering the RLIMIT_CPU soft limit when a SIGXCPU handler
has been installed, Linux invokes the signal handler *and* raises
the soft limit by one second. This behavior repeats until the
limit is encountered. No other implementation that I tested
(Solaris 10, FreeBSD 9.0, OpenBSD 5.0) does this, and it seems
unlikely to be POSIX-conformant. The (Linux-specific)
RLIMIT_RTTIME soft limit exhibits similar behavior.
Michael Kerrisk
Point reader at discussion of /proc/[pid]/limits in proc(5)
io_getevents.2
Michael Kerrisk
io_getevents() may cause segfault when called with invalid ctx_id
For reference see: http://marc.info/?l=linux-aio&m=130089887002435&w=2
recv.2
Michael Kerrisk [Eric Dumazet]
UNIX domain sockets support MSG_TRUNC since 3.4
sendmmsg.2
Elie De Brauwer
Add example program for sendmmsg()
stat.2
Simon Paillard
Clarify description of EOVERFLOW error
The EOVERFLOW error is not only for st_size, but also
inode and block size fields. See glibc source file
sysdeps/unix/sysv/linux/xstatconv.c and kernel source
file fs/stat.c. Also, fix bit/byte confusion
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604928
syscalls.2
Michael Kerrisk
Update various references to "i386" to "x86"
Michael Kerrisk
Add s390_runtime_instr(2)
sysctl.2
Michael Kerrisk
Mention CONFIG_SYSCTL_SYSCALL
Michael Kerrisk
Calls to sysctl() log warnings to the kernel log since 2.6.24
syslog.2
Michael Kerrisk
Substantially reorganize discussion of commands
Make the layout of the discussion of the commands
more readable.
Michael Kerrisk
Add kernel symbolic 'type' names
Michael Kerrisk
Clarify SYSLOG_ACTION_SIZE_UNREAD semantics
SYSLOG_ACTION_SIZE_UNREAD returns the number of bytes
available for reading via SYSLOG_ACTION_READ.
Michael Kerrisk
Clarify where SYSLOG_ACTION_READ_ALL places data it reads
Michael Kerrisk
Clarify semantics of SYSLOG_ACTION_CLEAR
The SYSLOG_ACTION_CLEAR command (5) does not really clear
the ring buffer; rather it affects the semantics of what
is returned by commands 3 (SYSLOG_ACTION_READ_ALL) and
4 (SYSLOG_ACTION_READ_CLEAR).
Michael Kerrisk
Clarify discussion of privileges for commands 3 and 10
Michael Kerrisk
Add mention of CONFIG_LOG_BUF_SHIFT
wait.2

Update description of ifa_data to Linux 2.6+ reality
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=526778
memcmp.3
Michael Kerrisk [Jon Grant]
Enhance RETURN VALUE text and remove redundant text from DESCRIPTION
Note that sign of result equals sign of difference between
first two bytes that differ (treated as "unsigned char")."
mkstemp.3
Michael Kerrisk [Florian Weimer]
Deemphasize discussion of mode 066 in glibc 2.0.6
Glibc 2.0.6 is now so ld that the discussion of details
of that version can be deemphasized placing just under
NOTES.
See https://bugzilla.kernel.org/show_bug.cgi?id=51811
strcmp.3
Michael Kerrisk [Jon Grant]
Enhance RETURN VALUE text and remove redundant text from DESCRIPTION
Note that sign of result equals sign of difference between
first two bytes that differ (treated as "unsigned char")."
ttyname.3
Michael Kerrisk
Fix confused text in ERRORS
The existing text suggested that the ERRORS applied
only for ttyname_r(). However, 2 of the 3 errors
can occur for ttyname().
