Changes to individual pages
|
||||
---------------------------
|
||||
|
||||
_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.
|
||||
Michael Kerrisk
|
||||
Reorder ERRORS list
|
||||
Some errors were listed under a separate "may" heading.
|
||||
There's probably no real need to do this; integrate
|
||||
those errors into the main list.
|
||||
|
||||
exit_group.2
|
||||
Michael Kerrisk
|
||||
Note that since glibc 2.3, exit(2) invokes exit_group()
|
||||
|
||||
futex.2
|
||||
Michael Kerrisk
|
||||
Mention that glibc provides no wrapper function for futex()
|
||||
|
||||
get_thread_area.2
|
||||
Michael Kerrisk
|
||||
Note that glibc provides no wrapper for this system call
|
||||
|
||||
getdomainname.2
|
||||
Michael Kerrisk
|
||||
Substantial rewrite
|
||||
Expand description of setdomainname() and getdomainname().
|
||||
Note that getdomainname() is implemented as a library function
|
||||
in glibc.
|
||||
Note limits on size of domain name.
|
||||
Reorganize ERRORS list.
|
||||
|
||||
gethostname.2
|
||||
Michael Kerrisk
|
||||
Various parts rewritten
|
||||
Write a paragraph describing sethostname().
|
||||
|
||||
Clarify differences between glibc's gethostbyname() and
|
||||
the kernel gethostbyname() system calls.
|
||||
|
||||
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
|
||||
Document EOVERFLOW error
|
||||
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.

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.

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

|

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).

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.

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

Changes to individual pages
|
||||
---------------------------
|
||||
|
||||
_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.
|
||||
Michael Kerrisk
|
||||
Reorder ERRORS list
|
||||
Some errors were listed under a separate "may" heading.
|
||||
There's probably no real need to do this; integrate
|
||||
those errors into the main list.
|
||||
|
||||
exit_group.2
|
||||
Michael Kerrisk
|
||||
Note that since glibc 2.3, exit(2) invokes exit_group()
|
||||
|
||||
futex.2
|
||||
Michael Kerrisk
|
||||
Mention that glibc provides no wrapper function for futex()
|
||||
|
||||
get_thread_area.2
|
||||
Michael Kerrisk
|
||||
Note that glibc provides no wrapper for this system call
|
||||
|
||||
getdomainname.2
|
||||
Michael Kerrisk
|
||||
Substantial rewrite
|
||||
Expand description of setdomainname() and getdomainname().
|
||||
Note that getdomainname() is implemented as a library function
|
||||
in glibc.
|
||||
Note limits on size of domain name.
|
||||
Reorganize ERRORS list.
|
||||
|
||||
gethostname.2
|
||||
Michael Kerrisk
|
||||
Various parts rewritten
|
||||
Write a paragraph describing sethostname().
|
||||
|
||||
Clarify differences between glibc's gethostbyname() and
|
||||
the kernel gethostbyname() system calls.
|
||||
|
||||
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).
|
||||

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
|

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.

It's a subtle point, but if a registered function itself

with on_exit(3) will see the exit status given to the more

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

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.
