2016-03-18deduplicate bits/mman.hSzabolcs Nagy1-0/+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.
2016-01-26add new PTRACE_SECCOMP_GET_FILTER ptrace commandSzabolcs Nagy1-0/+1
allows the tracer to dump the bpf seccomp filters of the tracee, new in linux v4.4, commit f8e529ed941ba2bbcbf310b575d968159ce7e895
2016-01-26add MCL_ONFAULT and MLOCK_ONFAULT mlockall and mlock2 flagsSzabolcs Nagy1-0/+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
2016-01-26add new PTRACE_O_SUSPEND_SECCOMP ptrace optionSzabolcs Nagy1-1/+2
allows a ptracer process to disable/enable seccomp filters of the traced process, useful for checkpoint/restore, new in v4.3 commit 13c4a90119d28cfcb6b5bdd820c233b86c2b0237
2016-01-26add new PR_CAP_AMBIENT and related defines to sys/prctl.hSzabolcs Nagy1-0/+6
ambient capability mask is new in linux v4.3, commit 58319057b7847667f0c9585b9de0e8932b0fdb08
2016-01-24add MS_LAZYTIME mount option to sys/mount.hSzabolcs Nagy1-1/+2
new in linux 4.0 commit 0ae45f63d4ef8d8eeec49c7d8b44a1775fff13e8, used to update atime/mtime/ctime only in memory when possible.
2016-01-24add AF_MPLS (PF_MPLS) address family to socket.hSzabolcs Nagy1-0/+2
new in linux 4.0 commit 0189197f441602acdca3f97750d392a895b778fd.
2016-01-24add MSG_FASTOPEN sendmsg/sendto flag to socket.hSzabolcs Nagy1-0/+1
This was new in linux 3.5 in commit cf60af03ca4e71134206809ea892e49b92a88896, needed for tcp fastopen feature (sending data in TCP SYN packet).
2015-07-21socket.h: fix SO_* for mipsRoman Yeryomin1-3/+3
Signed-off-by: Roman Yeryomin <roman@ubnt.com>
2015-05-28add missing legacy LFS64 macros in sys/resource.hRich Felker1-0/+3
based on patch by Felix Janda, with RLIM64_SAVED_CUR and RLIM64_SAVED_MAX added for completeness.
2015-04-17add PR_*_FP_MODE prctl optionsSzabolcs Nagy1-0/+5
new in linux v4.0, commit 9791554b45a2acc28247f66a5fd5bbc212a6b8c8 used to work around a floating-point abi issue on mips
2015-04-17add PR_MPX_*_MANAGEMENT prctl optionsSzabolcs Nagy1-0/+3
new in linux v3.19, commit fe3d197f84319d3bce379a9c0dc17b1f48ad358c used for on-demand kernel allocation of bounds tables for mpx on x86
2015-03-04declare incomplete type struct itimerspec in timerfd.hRich Felker1-0/+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.
2015-02-09add new socket options SO_INCOMING_CPU, SO_ATTACH_BPF, SO_DETACH_BPFSzabolcs Nagy1-0/+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.
2015-01-30move MREMAP_MAYMOVE and MREMAP_FIXED out of bitsTrutz Behn1-0/+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.
2014-12-23add new prctl command PR_SET_MM_MAP to sys/prctl.hSzabolcs Nagy1-0/+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.
2014-09-05fix macros for LFS *64_t types in sys/stat.h, sys/types.h, glob.hSzabolcs Nagy2-2/+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.
2014-07-20add new PR_SET_THP_DISABLE and PR_GET_THP_DISABLE prctl flagsSzabolcs Nagy1-0/+3
they can be used to set or query if transparent huge pages are disabled. introduced in linux 3.15 commit a0715cc22601e8830ace98366c0c2bd8da52af52
2014-06-19implement sendmmsg and recvmmsgRich Felker1-0/+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.
2014-05-30fix POSIX namespace pollution in sys/types.hSzabolcs Nagy1-10/+6
int8_t, u_int8_t, etc types are moved under _BSD_SOURCE
2014-05-30add SO_BPF_EXTENSIONS socket optionSzabolcs Nagy1-0/+1
this was introduced to query BPF extension support with getsockopt in linux 3.14, commit ea02f9411d9faa3553ed09ce0ec9f00ceae9885e
2014-04-15fix RLIMIT_ constants for mipsSzabolcs Nagy1-2/+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.
2014-04-07add getauxval functionRich Felker1-0/+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.
2014-03-11move struct semid_ds to from shared sys/sem.h to bitsRich Felker1-16/+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.
2014-03-08in sys/procfs.h, avoid using __WORDSIZE macroRich Felker1-1/+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.
2014-02-25sys/socket.h: add the SO_MAX_PACING_RATE SOL_SOCKET optionSzabolcs Nagy1-0/+1
introduced in linux v3.13, 62748f32d501f5d3712a7c372bbb92abc7c62bc7
2014-02-23sys/shm.h: move arch specific structs to bits/rofl0r1-16/+7
2014-02-22sys/sem.h: cheat and make all longs use time_t insteadrofl0r1-8/+8
most of the members should be time_t anyway, and time_t has the correct semantics for "syscall_long", so it works on all archs, even x32.
2014-02-11fix signed and unsigned comparision in macros in public headersSzabolcs Nagy1-1/+1
gcc -Wsign-compare warns about expanded macros that were defined in standard headers (before gcc 4.8) which can make builds fail that use -Werror. changed macros: WIFSIGNALED, __CPU_op_S
2014-02-05add nonstandard timespec/timeval conversion macros in sys/time.hRich Felker1-0/+11
these are poorly designed (illogical argument order) and even poorly implemented (brace issues) on glibc, but unfortunately some software is using them. we could consider removing them again in the future at some point if they're documented as deprecated, but for now the simplest thing to do is just to provide them under _GNU_SOURCE.
2014-01-08fix namespace violation in sys/shm.hRich Felker1-6/+8
in fixing this, I've changed the logic from ugly #if/#else blocks inside the struct shm_info definition to a fixed struct definition and optional macros to rename the elements. this will be helpful if we need to move shm_info to a bits header in the future, as it will keep the feature test logic out of bits.
2014-01-08fix remaining known namespace violations for netinet/in.hRich Felker1-0/+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.
2014-01-07fix signedness of pgoff argument to remap_file_pagesRich Felker1-1/+1
both the kernel and glibc agree that this argument is unsigned; the incorrect type ssize_t came from erroneous man pages.
2014-01-07remove sys/sysctl.hRich Felker1-17/+0
this functionality has essentially always been deprecated in linux, and was never supported by musl. the presence of the header was reported to cause some software to attempt to use the nonexistant function, so removing the header is the cleanest solution.
2014-01-07fix incorrect type for wd argument of inotify_rm_watchRich Felker1-1/+1
this was wrong since the original commit adding inotify, and I don't see any explanation for it. not even the man pages have it wrong. it was most likely a copy-and-paste error.
2014-01-02add fanotify syscall wrapper and headerrofl0r1-0/+73
2013-12-29fix struct signalfd_siginfoTimo Teräs1-2/+3
ssi_ptr is really 64-bit in kernel, so fix that. assuming sizeof(void*) for it also caused incorrect padding for 32-bits, as the following 64-bits are aligned to 64-bits (and the padding was not taken into account), so fix the padding as well. add addr_lsb field while there.
2013-12-20add sys/quota.h and quotactl syscall wrapperRich Felker1-0/+104
based on patch by Timo Teräs.
2013-12-04move struct ucred under _GNU_SOURCE in sys/socket.h for clean posix namespaceSzabolcs Nagy1-0/+2
2013-12-04fix SHUT_WR typo in sys/socket.h and duplicate definitions of SHUT_*Szabolcs Nagy1-5/+1
2013-11-24use 0 instead of NULL in headers where NULL is not definedSzabolcs Nagy1-1/+1
some macros in sys/mtio.h and syslog.h used NULL without defining it
2013-11-23timeradd/timersub: cast result to void to get rid of warningsrofl0r1-2/+2
previously: timersub(&now, t, &diff); warning: value computed is not used [-Wunused-value]
2013-11-09adjust sys/wait.h not to produde errors in strict ISO C feature profileRich Felker1-3/+7
siginfo_t is not available from signal.h when the strict ISO C feature profile (e.g. passing -std=c99 to gcc without defining any other feature test macros) is used, but the type is needed to declare waitid. using sys/wait.h (or any POSIX headers) in strict ISO C mode is an application bug, but in the interest of compatibility, it's best to avoid producing gratuitous errors. the simplest fix I could find is suppressing the declaration of waitid (and also signal.h inclusion, since it's not needed for anything else) in this case, while still exposing everything else in sys/wait.h
2013-10-25add legacy ftime function and sys/timeb.hRich Felker1-0/+22
despite being marked legacy, this was specified by SUSv3 as part of the XSI option; only the most recent version of the standard dropped it. reportedly there's actual code using it.
2013-10-18fix typo in socket.h (wrong macro name)Szabolcs Nagy1-1/+1
2013-09-16sys/resource.h: add PRIO_MIN and PRIO_MAX for getpriority and setprioritySzabolcs Nagy1-0/+3
These constants are not specified by POSIX, but they are in the reserved namespace, glibc and bsd systems seem to provide them as well. (Note that POSIX specifies -NZERO and NZERO-1 to be the limits, but PRIO_MAX equals NZERO)
2013-09-15sys/socket.h: add new SO_BUSY_POLL socket optionSzabolcs Nagy1-0/+1
low latency busy poll sockets are new in linux v3.11
2013-09-15ptrace.h: add new ptrace requests to get/set sigmaskSzabolcs Nagy1-0/+2
PTRACE_GETSIGMASK and PTRACE_SETSIGMASK were added in linux v3.11 and used by checkpoint/restore tools
2013-08-21add SUN_LEN macro to sys/un.h under appropriate feature testsRich Felker1-0/+19
this is ugly and useless, but it seems to be the least-ugly way to provide it...
2013-08-14add missing MSG_EXCEPT in sys/msg.hRich Felker1-0/+1
