* implement sendmmsg and recvmmsgRich Felker2014-06-191-0/+11
| | | | | | | these are not pure syscall wrappers because they have to work around kernel API bugs on 64-bit archs. the workarounds could probably be made somewhat more efficient, but at the cost of more complexity. this may be revisited later.
* add SO_BPF_EXTENSIONS socket optionSzabolcs Nagy2014-05-301-0/+1
| | | | | this was introduced to query BPF extension support with getsockopt in linux 3.14, commit ea02f9411d9faa3553ed09ce0ec9f00ceae9885e
* sys/socket.h: add the SO_MAX_PACING_RATE SOL_SOCKET optionSzabolcs Nagy2014-02-251-0/+1
| | | | introduced in linux v3.13, 62748f32d501f5d3712a7c372bbb92abc7c62bc7
* fix remaining known namespace violations for netinet/in.hRich Felker2014-01-081-0/+4
| | | | | | | | | | | | | | | | | | | | the imr_, imsf_, ip6_, ip6m_, ipi_, ipi6_, SCM_, and SOL_ prefixes are not in the reserved namespace for this header. thus the constants and structures using them need to be protected under appropriate feature test macros. this also affects some headers which are permitted to include netinet/in.h, particularly netdb.h and arpa/inet.h. the SOL_ macros are moved to sys/socket.h where they are in the reserved namespace (SO*). they are still accessible via netinet/in.h since it includes sys/socket.h implicitly (which is permitted). the SCM_SRCRT macro is simply removed, since the definition used for it, IPV6_RXSRCRT is not defined anywhere. it could be re-added, this time in sys/socket.h, if the appropriate value can be determined; however, given that the erroneous definition was not caught, it is unlikely that any software actually attempts to use SCM_SRCRT.
* move struct ucred under _GNU_SOURCE in sys/socket.h for clean posix namespaceSzabolcs Nagy2013-12-041-0/+2

* fix SHUT_WR typo in sys/socket.h and duplicate definitions of SHUT_*Szabolcs Nagy2013-12-041-5/+1
|
* fix typo in socket.h (wrong macro name)Szabolcs Nagy2013-10-181-1/+1
|
* sys/socket.h: add new SO_BUSY_POLL socket optionSzabolcs Nagy2013-09-151-0/+1
| | | | low latency busy poll sockets are new in linux v3.11
* add protocol families PF_IB and PF_VSOCK to socket.hSzabolcs Nagy2013-07-251-1/+5
| | | | | | | | linux commit 8d36eb01da5d371feffa280e501377b5c450f5a5 (2013-05-29) added PF_IB for InfiniBand linux commit d021c344051af91f42c5ba9fdedc176740cbd238 (2013-02-06) added PF_VSOCK for VMware sockets
* add SO_SELECT_ERR_QUEUE to socket.hSzabolcs Nagy2013-07-241-0/+1
| | | | introduced in linux-v3.10 commit 7d4c04fc170087119727119074e72445f2bb192b
* add new socket options to sys/socket.h following linuxSzabolcs Nagy2013-04-011-2/+17
|
* fix some obscure header type size/alignment issuesRich Felker2013-03-041-4/+2
|
* add missing protocol families to sys/socket.hSzabolcs Nagy2013-01-121-1/+11
| | | | | missing protocol families based on current linux headers: PF_RDS, PF_LLC, PF_CAN, PF_TIPC, PF_NFC
* socket.h: add SO_(SND/RCV)BUFFORCE to generic blockrofl0r2012-12-191-0/+2
|
* disable SO_REUSEPORT in sys/socket.hRich Felker2012-11-151-1/+1
| | | | | | although a number is reserved for it, this option is not implemented on Linux and does not work. defining it causes some applications to use it, and subsequently break due to its failure.
* fix numerous mips abi constant definition mismatchesRich Felker2012-11-051-0/+7
|
* always expose accept4Rich Felker2012-09-291-4/+1
| | | | it will be in the next version of POSIX
* add acct, accept4, setns, and dup3 syscalls (linux extensions)Rich Felker2012-09-081-0/+4
| | | | based on patch by Justin Cormack
* remove all remaining redundant __restrict/__inline/_Noreturn defsRich Felker2012-09-081-5/+1
|
* use restrict everywhere it's required by c99 and/or posix 2008Rich Felker2012-09-061-5/+11
| | | | | | | | to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
* fix socket.h on mipsRich Felker2012-08-051-0/+3
| | | | | why does mips have to be gratuitously incompatible in every possible imaginable way?
* workaround another sendmsg kernel bug on 64-bit machinesRich Felker2012-07-121-7/+0
| | | | | | | | | the kernel wrongly expects the cmsg length field to be size_t instead of socklen_t. in order to work around the issue, we have to impose a length limit and copy to a local buffer. the length limit should be more than sufficient for any real-world use; these headers are only used for passing file descriptors and permissions between processes over unix sockets.
* cleanup more bits cruft (sysmacros and socket)Rich Felker2011-09-181-0/+196
|
* fix some struct padding to match LSB/glibc ABI where it may be helpfulRich Felker2011-06-161-2/+4
|
* extensive header cleanup for standards conformance & correctnessRich Felker2011-02-141-0/+1
| | | | | thanks to Peter Mazinger (psm) for pointing many of these issues out and submitting a patch on which this commit is loosely based
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+64
