| * | fix undefined pointer arithmetic in CMSG_NXTHDR macro•••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.

| * | deduplicate bits/mman.h•••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 MS_LAZYTIME mount option to sys/mount.h•••new in linux 4.0 commit 0ae45f63d4ef8d8eeec49c7d8b44a1775fff13e8,
used to update atime/mtime/ctime only in memory when possible.

| * | add MSG_FASTOPEN sendmsg/sendto flag to socket.h•••This was new in linux 3.5 in commit cf60af03ca4e71134206809ea892e49b92a88896,
needed for tcp fastopen feature (sending data in TCP SYN packet).

| Roman Yeryomin | 2015-07-21 | 1 | -3/+3 |
| * | add missing legacy LFS64 macros in sys/resource.h•••based on patch by Felix Janda, with RLIM64_SAVED_CUR and
RLIM64_SAVED_MAX added for completeness.

| * | add PR_*_FP_MODE prctl options•••new in linux v4.0, commit 9791554b45a2acc28247f66a5fd5bbc212a6b8c8
used to work around a floating-point abi issue on mips

| * | add PR_MPX_*_MANAGEMENT prctl options•••new in linux v3.19, commit fe3d197f84319d3bce379a9c0dc17b1f48ad358c
used for on-demand kernel allocation of bounds tables for mpx on x86
| Szabolcs Nagy | 2015-04-17 | 1 | -0/+3 |
| * | declare incomplete type struct itimerspec in timerfd.h•••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.
| Rich Felker | 2015-03-04 | 1 | -0/+2 |
| * | add new socket options SO_INCOMING_CPU, SO_ATTACH_BPF, SO_DETACH_BPF•••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.
| Szabolcs Nagy | 2015-02-09 | 1 | -0/+4 |
| * | move MREMAP_MAYMOVE and MREMAP_FIXED out of bits•••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.
| Trutz Behn | 2015-01-30 | 1 | -0/+2 |
| * | add new prctl command PR_SET_MM_MAP to sys/prctl.h•••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.h•••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.
| Szabolcs Nagy | 2014-09-05 | 2 | -2/+2 |
| * | add new PR_SET_THP_DISABLE and PR_GET_THP_DISABLE prctl flags•••they can be used to set or query if transparent huge pages are disabled.
introduced in linux 3.15 commit a0715cc22601e8830ace98366c0c2bd8da52af52
| Szabolcs Nagy | 2014-07-20 | 1 | -0/+3 |
| * | implement sendmmsg and recvmmsg•••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.
| Rich Felker | 2014-06-19 | 1 | -0/+11 |
| * | fix POSIX namespace pollution in sys/types.h•••int8_t, u_int8_t, etc types are moved under _BSD_SOURCE
| Szabolcs Nagy | 2014-05-30 | 1 | -10/+6 |
| * | add SO_BPF_EXTENSIONS socket option•••this was introduced to query BPF extension support with getsockopt
in linux 3.14, commit ea02f9411d9faa3553ed09ce0ec9f00ceae9885e
| Szabolcs Nagy | 2014-05-30 | 1 | -0/+1 |
| * | fix RLIMIT_ constants for mips•••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.
| Szabolcs Nagy | 2014-04-15 | 1 | -2/+5 |
| * | add getauxval function•••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.
| Rich Felker | 2014-04-07 | 1 | -0/+16 |
| * | move struct semid_ds to from shared sys/sem.h to bits•••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.
| Rich Felker | 2014-03-11 | 1 | -16/+1 |
| * | in sys/procfs.h, avoid using __WORDSIZE macro•••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.
| Rich Felker | 2014-03-08 | 1 | -1/+1 |
| * | sys/socket.h: add the SO_MAX_PACING_RATE SOL_SOCKET option•••introduced in linux v3.13, 62748f32d501f5d3712a7c372bbb92abc7c62bc7
| Szabolcs Nagy | 2014-02-25 | 1 | -0/+1 |
| * | sys/shm.h: move arch specific structs to bits/ | rofl0r | 2014-02-23 | 1 | -16/+7 |
| * | sys/sem.h: cheat and make all longs use time_t instead•••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.
| rofl0r | 2014-02-22 | 1 | -8/+8 |
| * | fix signed and unsigned comparision in macros in public headers•••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
| Szabolcs Nagy | 2014-02-11 | 1 | -1/+1 |
| * | add nonstandard timespec/timeval conversion macros in sys/time.h•••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.
| Rich Felker | 2014-02-05 | 1 | -0/+11 |
| * | fix namespace violation in sys/shm.h•••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.
| Rich Felker | 2014-01-08 | 1 | -6/+8 |
| * | fix remaining known namespace violations for netinet/in.h•••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.
| Rich Felker | 2014-01-08 | 1 | -0/+4 |
| * | fix signedness of pgoff argument to remap_file_pages•••both the kernel and glibc agree that this argument is unsigned; the
incorrect type ssize_t came from erroneous man pages.
| Rich Felker | 2014-01-07 | 1 | -1/+1 |
| * | remove sys/sysctl.h•••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.
| Rich Felker | 2014-01-07 | 1 | -17/+0 |
| * | fix incorrect type for wd argument of inotify_rm_watch•••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.
| Rich Felker | 2014-01-07 | 1 | -1/+1 |
| * | add fanotify syscall wrapper and header | rofl0r | 2014-01-02 | 1 | -0/+73 |
| * | fix struct signalfd_siginfo•••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.
| Timo Teräs | 2013-12-29 | 1 | -2/+3 |
| * | add sys/quota.h and quotactl syscall wrapper•••based on patch by Timo Teräs.
| Rich Felker | 2013-12-20 | 1 | -0/+104 |
| * | move struct ucred under _GNU_SOURCE in sys/socket.h for clean posix namespace | Szabolcs Nagy | 2013-12-04 | 1 | -0/+2 |
| * | fix SHUT_WR typo in sys/socket.h and duplicate definitions of SHUT_* | Szabolcs Nagy | 2013-12-04 | 1 | -5/+1 |
| * | use 0 instead of NULL in headers where NULL is not defined•••some macros in sys/mtio.h and syslog.h used NULL without defining it
| Szabolcs Nagy | 2013-11-24 | 1 | -1/+1 |
| * | timeradd/timersub: cast result to void to get rid of warnings•••previously:
timersub(&now, t, &diff);
warning: value computed is not used [-Wunused-value]
| rofl0r | 2013-11-23 | 1 | -2/+2 |
| * | adjust sys/wait.h not to produde errors in strict ISO C feature profile•••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
| Rich Felker | 2013-11-09 | 1 | -3/+7 |
| * | add legacy ftime function and sys/timeb.h•••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.
| Rich Felker | 2013-10-25 | 1 | -0/+22 |
| * | fix typo in socket.h (wrong macro name) | Szabolcs Nagy | 2013-10-18 | 1 | -1/+1 |
