| * | 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.

| * | fix POSIX namespace pollution in sys/types.h•••int8_t, u_int8_t, etc types are moved under _BSD_SOURCE

| * | add SO_BPF_EXTENSIONS socket option•••this was introduced to query BPF extension support with getsockopt
in linux 3.14, commit ea02f9411d9faa3553ed09ce0ec9f00ceae9885e

| * | 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.

| * | 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.

| * | sys/socket.h: add the SO_MAX_PACING_RATE SOL_SOCKET option•••introduced in linux v3.13, 62748f32d501f5d3712a7c372bbb92abc7c62bc7

| * | 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.

| * | add sys/quota.h and quotactl syscall wrapper•••based on patch by Timo Teräs.
| Rich Felker | 2013-12-20 | 1 | -0/+104 |

| * | 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 |
| * | sys/resource.h: add PRIO_MIN and PRIO_MAX for getpriority and setpriority•••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)

| * | sys/socket.h: add new SO_BUSY_POLL socket option•••low latency busy poll sockets are new in linux v3.11
| Szabolcs Nagy | 2013-09-15 | 1 | -0/+1 |
| * | ptrace.h: add new ptrace requests to get/set sigmask•••PTRACE_GETSIGMASK and PTRACE_SETSIGMASK were added in linux v3.11
and used by checkpoint/restore tools
| Szabolcs Nagy | 2013-09-15 | 1 | -0/+2 |
| * | add SUN_LEN macro to sys/un.h under appropriate feature tests•••this is ugly and useless, but it seems to be the least-ugly way to
provide it...

| * | add missing MSG_EXCEPT in sys/msg.h | Rich Felker | 2013-08-14 | 1 | -0/+1 |
| * | fix definitions of WIFSTOPPED and WIFSIGNALED to support up to signal 127•••mips has signal numbers up to 127 (formerly, up to 128, but the last
one never worked right and caused kernel panic when used), so 127 in
the "signal number" field of the wait status is insufficient for
determining that the process was stopped. in addition, a nonzero value
in the upper bits must be present, indicating the signal number which
caused the process to be stopped.

the linux-mips mailing list, archived at:
http://www.linux-mips.org/archives/linux-mips/2013-06/msg00552.html
and in the associated thread about fixing the mips kernel bug.
commit 4a96b948687166da26a6c327e6c6733ad2336c5c fixed the
corresponding issue in uClibc, but introduced a multiple-evaluation
issue for the WIFSTOPPED macro.
for the most part, none of these issues affected pure musl systems,
since musl has up until now (incorrectly) defined SIGRTMAX as 64 on
all archs, even mips. however, interpreting status of non-musl
programs on mips may have caused problems. with this change, the full
range of signal numbers can be made available on mips.

| * | add wrapper headers, with warnings, for various incorrect names under sys•••also add a warning to the existing sys/poll.h. the warning is absent
from sys/dir.h because it is actually providing a slightly different
API to the program, and thus just replacing the #include directive is
not a valid fix to programs using this one.

| * | move register_t and u_int64_t (back) to alltypes•••during the header refactoring, I had moved u_int64_t out of alltypes
under the assumption that we could just use long long everywhere.
however, it seems some broken applications make inconsistent mixed use
of u_int64_t and uint64_t, resulting in build errors when the
underlying type differs.
| Rich Felker | 2013-07-22 | 1 | -2/+5 |
| * | refactor headers, especially alltypes.h, and improve C++ ABI compat•••the arch-specific bits/alltypes.h.sh has been replaced with a generic
alltypes.h.in and minimal arch-specific bits/alltypes.h.in.
this commit is intended to have no functional changes except:
- exposing additional symbols that POSIX allows but does not require
- changing the C++ name mangling for some types
- fixing the signedness of blksize_t on powerpc (POSIX requires signed)
- fixing the limit macros for sig_atomic_t on x86_64
- making dev_t an unsigned type (ABI matching goal, and more logical)
in addition, some types that were wrongly defined with long on 32-bit
archs were changed to int, and vice versa; this change is
non-functional except for the possibility of making pointer types
mismatch, and only affects programs that were using them incorrectly,
and only at build-time, not runtime.
the following changes were made in the interest of moving
non-arch-specific types out of the alltypes system and into the
headers they're associated with, and also will tend to improve
application compatibility:
- netdb.h now includes netinet/in.h (for socklen_t and uint32_t)
- netinet/in.h now includes sys/socket.h and inttypes.h
- sys/resource.h now includes sys/time.h (for struct timeval)
- sys/wait.h now includes signal.h (for siginfo_t)
- langinfo.h now includes nl_types.h (for nl_item)
for the types in stdint.h:
- types which are of no interest to other headers were moved out of
the alltypes system.
- fast types for 8- and 64-bit are hard-coded (at least for now); only
the 16- and 32-bit ones have reason to vary by arch.
and the following types have been changed for C++ ABI purposes;
- mbstate_t now has a struct tag, __mbstate_t
- FILE's struct tag has been changed to _IO_FILE
- DIR's struct tag has been changed to __dirstream
- locale_t's struct tag has been changed to __locale_struct
- pthread_t is defined as unsigned long in C++ mode only
- fpos_t now has a struct tag, _G_fpos64_t
- fsid_t's struct tag has been changed to __fsid_t
- idtype_t has been made an enum type (also required by POSIX)
- nl_catd has been changed from long to void *
- siginfo_t's struct tag has been removed
- sigset_t's has been given a struct tag, __sigset_t
- stack_t has been given a struct tag, sigaltstack
- suseconds_t has been changed to long on 32-bit archs
- [u]intptr_t have been changed from long to int rank on 32-bit archs
- dev_t has been made unsigned
summary of tests that have been performed against these changes:
- nsz's libc-test (diff -u before and after)
- C++ ABI check symbol dump (diff -u before, after, glibc)
- grepped for __NEED, made sure types needed are still in alltypes
- built gcc 3.4.6

| * | add UIO_MAXIOV macro in sys/uio.h•••while there's no POSIX namespace provision for UIO_* in uio.h, this
exact macro name is reserved in XBD 2.2.2. apparently some
glibc-centric software expects it to exist, so let's provide it.
| Rich Felker | 2013-07-19 | 1 | -0/+2 |
| * | add NFDBITS in sys/select.h with appropriate feature tests•••the main use for this macro seems to be knowing the correct allocation
granularity for dynamic-sized fd_set objects. such usage is
non-conforming and results in undefined behavior, but it is widespread
in applications.

| * | add legacy sys/ttydefaults.h header | rofl0r | 2013-07-03 | 1 | -0/+39 |
| * | fix shifts possibly larger than type in major() macro•••in theory this should not be an issue, since major() should only be
applied to type dev_t, which is 64-bit. however, it appears some
applications are not using dev_t but a smaller integer type (which
works on Linux because the kernel's dev_t is really only 32-bit). to
avoid the undefined behavior, do it as two shifts.
| Rich Felker | 2013-06-29 | 1 | -1/+1 |
| * | work around wrong kernel type for sem_nsems member of struct semid_ds•••rejecting invalid values for n is fine even in the case where a new
sem will not be created, since the kernel does its range checks on n
even in this case as well.
by default, the kernel will bound the limit well below USHRT_MAX
anyway, but it's presumably possible that an administrator could
override this limit and break things.
| Rich Felker | 2013-06-28 | 1 | -1/+9 |
| * | add missing type shmatt_t in sys/shm.h•••this type is not really intended to be used; it's just there to allow
implementations to choose the type for the shm_nattch member of
struct shmid_sh, presumably since historical implementations disagreed
on the type. in any case, it needs to be there, so now it is.
