| | | | | | SO_MEMINFO added in linux commit a2d133b1d465016d0d97560b11f54ba0ace56d3e SO_INCOMING_NAPI_ID added in 6d4339028b350efbf87c61e6d9e113e5373545c9 SO_COOKIE added in 5daab9db7b65df87da26fd8cfa695fb9546a1ddb
* add TFD_TIMER_CANCEL_ON_SET that timerfd.h was missingSzabolcs Nagy2017-11-051-0/+1
| | | | | linux commit 575b1967e10a1f3038266244d2c7a3ca6b99fed8 moved timerfd apis to a new uapi header which showed musl was missing this flag.
* add SCM_TIMESTAMPING_OPT_STATS and related TCP_ enums from linux v4.10Szabolcs Nagy2017-11-051-0/+1
| | | | | | | for tcp timestamp control messages, new in linux commit 1c885808e45601b2b6f68b30ac1d999e10b6f606 and export time measurements via tcp_info, added in linux commit efd90174167530c67a54273fd5d8369c87f9bd32
* add MS_NOREMOTELOCK mount flag from linux v4.9Szabolcs Nagy2016-12-291-0/+1
| | | | | for handling file locking on overlayfs. see linux commit c568d68341be7030f5647def68851e469b21ca11
* remove redundant feature test macro checks in sys/time.hRich Felker2016-11-071-5/+0
| | | | | this header is XSI-shaded itself and thus does not need to limit specific content to _XOPEN_SOURCE.
* fix various header namespace issues under feature-test-macro controlRich Felker2016-10-201-2/+5
| | | | reported and changes suggested by Daniel Sabogal.
* remove parameter names from public headersRich Felker2016-10-201-2/+2
| | | | | inclusion of these names was unintentional and in most cases is a namespace violation. Daniel Sabogal tracked down and reported these.
* fix misspelling of a legacy macro name in sys/param.hRich Felker2016-10-201-1/+1
|
* add bits/hwcap.h and include it in sys/auxv.hSzabolcs Nagy2016-10-201-0/+1
| | | | | | | | | aarch64, arm, mips, mips64, mipsn32, powerpc, powerpc64 and sh have cpu feature bits defined in linux for AT_HWCAP auxv entry, so expose those in sys/auxv.h it seems the mips hwcaps were never exposed to userspace neither by linux nor by glibc, but that's most likely an oversight.
* add PF_QIPCRTR, AF_QIPCRTR from linux v4.7 to sys/socket.hSzabolcs Nagy2016-08-301-1/+3
| | | | | macros for qualcom ip router protocol, new in linux commit bdabad3e363d825ddf9679dd431cca0b2c30f881
* make brace placement in public header typedef'd structs consistentRich Felker2016-07-031-2/+1
| | | | | | commit befa5866ee30d09c0c96e88af2eabff5911342ea performed this change for struct definitions that did not also involve typedef, but omitted the latter.
* make brace placement in public header struct definitions consistentRich Felker2016-07-039-32/+16
| | | | | | | | | | | | | | placing the opening brace on the same line as the struct keyword/tag is the style I prefer and seems to be the prevailing practice in more recent additions. these changes were generated by the command: find include/ arch/*/bits -name '*.h' \ -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} + and subsequently checked by hand to ensure that the regex did not pick up any false positives.
* fix misplaced indention in sys/procfs.hRich Felker2016-07-031-1/+1
|
* add RUSAGE_THREAD (Linux extension) definition to sys/resource.hRich Felker2016-06-291-0/+1
|
* fix incorrect definition of RUSAGE_CHILDREN in sys/resource.hRich Felker2016-06-291-1/+1
| | | | | | the kernel ABI value for RUSAGE_CHILDREN is -1, not 1. the latter is actually interpreted as RUSAGE_THREAD, to obtain values for just the calling thread and not the whole process.
* avoid padding gaps in struct sockaddr_storageRich Felker2016-06-091-1/+1
| | | | | | | | | | | | | | | | | compilers are free not to copy, or in some cases to clobber, padding bytes in a structure. while it's an aliasing violation, and thus undefined behavior, to copy or manipulate other sockaddr types using sockaddr_storage, it seems likely that traditional code attempts to do so, and the original intent of the sockaddr_storage structure was probably to allow such usage. in the interest of avoiding silent and potentially dangerous breakage, ensure that there are no actual padding bytes in sockaddr_storage by moving and adjusting the size of the __ss_padding member so that it fits exactly. this change also removes a silent assumption that the alignment of long is equal to its size.
* update sys/socket.h to linux v4.6Szabolcs Nagy2016-06-091-1/+19
| | | | | | | | | | | | kernel connection multiplexor macros AF_KCM, PF_KCM, SOL_KCM were added in linux commit ab7ac4eb9832e32a09f4e8042705484d2fb0aad3 MSG_BATCH sendmsg flag for performance optimization was added in linux commit f092276d85b82504e8a07498f4e9e0c51f06745c SOL_* macros are now synced with linux socket.h which is not a uapi header and glibc did not have the macros either, but that has changed http://sourceware.org/ml/libc-alpha/2016-05/msg00322.html
* add SO_CNX_ADVICE to sys/socket.h, new in linux v4.6Szabolcs Nagy2016-06-091-0/+1
| | | | | | new socket option so application can give advice about routing path quality of connected udp sockets, added in linux commit a87cb3e48ee86d29868d3f59cfb9ce1a8fa63314
* fix undefined pointer arithmetic in CMSG_NXTHDR macroRich Felker2016-05-221-3/+3
| | | | | | | | previously, the only way the stopping condition could be met with correct lengths in the headers invoked undefined behavior, adding sizeof(struct cmsghdr) beyond the end of the cmsg buffer. instead, compute and compare sizes rather than pointers.
* add MADV_FREE madvise command from linux v4.5Szabolcs Nagy2016-03-191-0/+1
| | | | | | allows the os to free the marked pages lazily on memory pressure. expected to increase malloc performance. new in linux commit 854e9ed09dedf0c19ac8640e91bcc74bc3f9e5c9
* add EPOLLEXCLUSIVE epoll flag from linux v4.5Szabolcs Nagy2016-03-191-0/+1
| | | | | | new flag for exclusive wakeup mode when an event source fd is attached to multiple epoll fds but they should not all receive the events. new in linux commit df0108c5da561c66c333bb46bfe3c1fc65905898
* add SO_ATTACH_REUSEPORT_[CE]BPF socket options from linux v4.5Szabolcs Nagy2016-03-191-1/+2
| | | | | | new socket options for setting classic or extended BPF program for sockets in a SO_REUSEPORT group. added in linux commit 538950a1b7527a0a52ccd9337e3fcd304f027f13
* deduplicate bits/mman.hSzabolcs Nagy2016-03-181-0/+59
| | | | | | | | | | | currently five targets use the same mman.h constants and the rest share most constants too, so move them to sys/mman.h before the bits/mman.h include where the differences can be corrected by redefinition of the macros. this fixes two minor bugs: POSIX_MADV_DONTNEED was wrong on most targets (it should be the same as MADV_DONTNEED), and sh defined the x86-only MAP_32BIT mmap flag.
* add new PTRACE_SECCOMP_GET_FILTER ptrace commandSzabolcs Nagy2016-01-261-0/+1
| | | | | allows the tracer to dump the bpf seccomp filters of the tracee, new in linux v4.4, commit f8e529ed941ba2bbcbf310b575d968159ce7e895
* add MCL_ONFAULT and MLOCK_ONFAULT mlockall and mlock2 flagsSzabolcs Nagy2016-01-261-0/+1
| | | | | | | | they lock faulted pages into memory (useful when a small part of a large mapped file needs efficient access), new in linux v4.4, commit b0f205c2a3082dd9081f9a94e50658c5fa906ff1 MLOCK_* is not in the POSIX reserved namespace for sys/mman.h
* add new PTRACE_O_SUSPEND_SECCOMP ptrace optionSzabolcs Nagy2016-01-261-1/+2
| | | | | | allows a ptracer process to disable/enable seccomp filters of the traced process, useful for checkpoint/restore, new in v4.3 commit 13c4a90119d28cfcb6b5bdd820c233b86c2b0237
* add new PR_CAP_AMBIENT and related defines to sys/prctl.hSzabolcs Nagy2016-01-261-0/+6
| | | | | ambient capability mask is new in linux v4.3, commit 58319057b7847667f0c9585b9de0e8932b0fdb08
* add MS_LAZYTIME mount option to sys/mount.hSzabolcs Nagy2016-01-241-1/+2
| | | | | new in linux 4.0 commit 0ae45f63d4ef8d8eeec49c7d8b44a1775fff13e8, used to update atime/mtime/ctime only in memory when possible.
* add AF_MPLS (PF_MPLS) address family to socket.hSzabolcs Nagy2016-01-241-0/+2
| | | | new in linux 4.0 commit 0189197f441602acdca3f97750d392a895b778fd.
* add MSG_FASTOPEN sendmsg/sendto flag to socket.hSzabolcs Nagy2016-01-241-0/+1
| | | | | This was new in linux 3.5 in commit cf60af03ca4e71134206809ea892e49b92a88896, needed for tcp fastopen feature (sending data in TCP SYN packet).
* socket.h: fix SO_* for mipsRoman Yeryomin2015-07-211-3/+3
| | | | Signed-off-by: Roman Yeryomin <roman@ubnt.com>
* add missing legacy LFS64 macros in sys/resource.hRich Felker2015-05-281-0/+3
| | | | | based on patch by Felix Janda, with RLIM64_SAVED_CUR and RLIM64_SAVED_MAX added for completeness.
* add PR_*_FP_MODE prctl optionsSzabolcs Nagy2015-04-171-0/+5
| | | | | new in linux v4.0, commit 9791554b45a2acc28247f66a5fd5bbc212a6b8c8 used to work around a floating-point abi issue on mips
* add PR_MPX_*_MANAGEMENT prctl optionsSzabolcs Nagy2015-04-171-0/+3
| | | | | new in linux v3.19, commit fe3d197f84319d3bce379a9c0dc17b1f48ad358c used for on-demand kernel allocation of bounds tables for mpx on x86
* declare incomplete type struct itimerspec in timerfd.hRich Felker2015-03-041-0/+2
| | | | | | normally time.h would provide a definition for this struct, but depending on the feature test macros in use, it may not be exposed, leading to warnings when it's used in the function prototypes.
* add new socket options SO_INCOMING_CPU, SO_ATTACH_BPF, SO_DETACH_BPFSzabolcs Nagy2015-02-091-0/+4
| | | | | | | | | | | | | these socket options are new in linux v3.19, introduced in commit 2c8c56e15df3d4c2af3d656e44feb18789f75837 and commit 89aa075832b0da4402acebd698d0411dcc82d03e with SO_INCOMING_CPU the cpu can be queried on which a socket is managed inside the kernel and optimize polling of large number of sockets accordingly. SO_ATTACH_BPF lets eBPF programs (created by the bpf syscall) to be attached to sockets.
* move MREMAP_MAYMOVE and MREMAP_FIXED out of bitsTrutz Behn2015-01-301-0/+2
| | | | | | the definitions are generic for all kernel archs. exposure of these macros now only occurs on the same feature test as for the function accepting them, which is believed to be more correct.
* add new prctl command PR_SET_MM_MAP to sys/prctl.hSzabolcs Nagy2014-12-231-0/+21
| | | | | | | | | | | | | | | | | PR_SET_MM_MAP was introduced as a subcommand for PR_SET_MM in linux v3.18 commit f606b77f1a9e362451aca8f81d8f36a3a112139e the associated struct type is replicated in sys/prctl.h using libc types. example usage: struct prctl_mm_map *p; ... prctl(PR_SET_MM, PR_SET_MM_MAP, p, sizeof *p); the kernel side supported struct size may be queried with the PR_SET_MM_MAP_SIZE subcommand.
* fix macros for LFS *64_t types in sys/stat.h, sys/types.h, glob.hSzabolcs Nagy2014-09-052-2/+2
| | | | | | there is no blksize64_t (blksize_t is always long) but there are fsblkcnt64_t and fsfilcnt64_t types in sys/stat.h and sys/types.h. and glob.h missed glob64_t.
* add new PR_SET_THP_DISABLE and PR_GET_THP_DISABLE prctl flagsSzabolcs Nagy2014-07-201-0/+3
| | | | | they can be used to set or query if transparent huge pages are disabled. introduced in linux 3.15 commit a0715cc22601e8830ace98366c0c2bd8da52af52
* 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.
* fix POSIX namespace pollution in sys/types.hSzabolcs Nagy2014-05-301-10/+6
| | | | int8_t, u_int8_t, etc types are moved under _BSD_SOURCE
* 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
* fix RLIMIT_ constants for mipsSzabolcs Nagy2014-04-151-2/+5
| | | | | | | The mips arch is special in that it uses different RLIMIT_ numbers than other archs, so allow bits/resource.h to override the default RLIMIT_ numbers (empty on all archs except mips). Reported by orc.
* add getauxval functionRich Felker2014-04-071-0/+16
| | | | | | | in a sense this implementation is incomplete since it doesn't provide the HWCAP_* macros for use with AT_HWCAP, which is perhaps the most important intended usage case for getauxval. they will be added at a later time.
* move struct semid_ds to from shared sys/sem.h to bitsRich Felker2014-03-111-16/+1
| | | | | | | | | | | | the definition was found to be incorrect at least for powerpc, and fixing this cleanly requires making the definition arch-specific. this will allow cleaning up the definition for other archs to make it more specific, and reversing some of the ugliness (time_t hacks) introduced with the x32 port. this first commit simply copies the existing definition to each arch without any changes. this is intentional, to make it easier to review changes made on a per-arch basis.
* in sys/procfs.h, avoid using __WORDSIZE macroRich Felker2014-03-081-1/+1
| | | | | | | this was problematic because several archs don't define __WORDSIZE. we could add it, but I would rather phase this macro out in the long term. in our version of the headers, UINTPTR_MAX is available here, so just use it instead.
* sys/socket.h: add the SO_MAX_PACING_RATE SOL_SOCKET optionSzabolcs Nagy2014-02-251-0/+1
| | | | introduced in linux v3.13, 62748f32d501f5d3712a7c372bbb92abc7c62bc7
* sys/shm.h: move arch specific structs to bits/rofl0r2014-02-231-16/+7
