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
