New and rewritten pages ----------------------- makedev.3 Michael Kerrisk New page for makedev(), major(), and minor() macros pthread_cleanup_push_defer_np.3 Michael Kerrisk New page for pthread_cleanup_push_defer_np(3) and pthread_cleanup_pop_restore_np(3) Newly documented interfaces in existing pages --------------------------------------------- accept.2 Michael Kerrisk Document accept4() system call, new in Linux 2.6.28 fmemopen.3 Petr Baudis Add description of open_wmemstream(3) tcp.7 Michael Kerrisk Document MSG_TRUNC flag for TCP sockets New and changed links --------------------- accept4.2 Michael Kerrisk New link to accept.2 accept.2 now documents the new accept4() system call. open_wmemstream.3 Petr Baudis New link to fmemopen.3 fmemopen.3 now documents open_wmemstream(). pthread_cleanup_pop_restore_np.3 Michael Kerrisk New link to new pthread_cleanup_push_defer_np.3 Global changes -------------- accept.2 listen.2 recv.2 getpeername.2 getsockname.2 shutdown.2 socketpair.2 Michael Kerrisk Global fix: SEE ALSO: add socket(7) bind.2 rcmd.3 capabilities.7 ip.7 Michael Kerrisk Global fix: s/reserved port/privileged port/ Some pages used one term, some pages the other term; make some consistency. connect.2 getpeername.2 getsockname.2 Michael Kerrisk Use consistent argument names Most other sockets pages are using the names 'addr' and 'addrlen'; make these pages do the same. getpeername.2 getsockname.2 getsockopt.2 recv.2 send.2 shutdown.2 sockatmark.3 socket.7 udplite.7 Michael Kerrisk SYNOPSIS: Rename socket file descriptor argument to 'sockfd' Many sockets man pages use the name 'sockfd' already. For consistency, changes the others to do so as well. gnu_dev_major.3 gnu_dev_makedev.3 gnu_dev_minor.3 major.3 minor.3 Michael Kerrisk New links to new makedev(3) page 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. Reviewed-by: Mats Wichmann Reviewed-by: Petr Baudis dlopen.3 Petr Baudis Describe confusing dladdr() behavior dladdr() will act unexpectedly if called from non-pic code on a compile-time-generated function pointer. fmemopen.3 Michael Kerrisk Add VERSIONS section Petr Baudis SEE OPEN: Add fopencookie(3) fopencookie(3) is used to implement fmemopen(). fopen.3 Petr Baudis SEE ALSO: Add fmemopen(3) and fopencookie(3) fopencookie.3 Petr Baudis fopencookie() needs _GNU_SOURCE feature test macro 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 Michael Kerrisk Retitled subsection "(Un)supported features" to "Sockets API" This is consistent with the recent change in tcp(7). -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
