| * | syscall organization overhaul•••now public syscall.h only exposes __NR_* and SYS_* constants and the
variadic syscall function. no macros or inline functions, no
__syscall_ret or other internal details, no 16-/32-bit legacy syscall
renaming, etc. this logic has all been moved to src/internal/syscall.h
with the arch-specific parts in arch/$(ARCH)/syscall_arch.h, and the
amount of arch-specific stuff has been reduced to a minimum.
changes still need to be reviewed/double-checked. minimal testing on
i386 and mips has already been performed.

| * | fix redundant _Noreturn def in err.h•••not sure why this was missed in the earlier commit.
| Rich Felker | 2012-09-08 | 1 | -7/+1 |
| * | remove all remaining redundant __restrict/__inline/_Noreturn defs | Rich Felker | 2012-09-08 | 14 | -76/+14 |
| * | sysmacros major/minor: result should have type unsigned int, not dev_t | Rich Felker | 2012-09-08 | 1 | -2/+2 |
| * | add linux tee syscall | Rich Felker | 2012-09-08 | 1 | -0/+1 |
| * | add linux sync_file_range syscall | Rich Felker | 2012-09-08 | 1 | -0/+4 |
| * | add linux readahead syscall | Rich Felker | 2012-09-08 | 1 | -0/+1 |
| * | add fallocate (nonstandardized) function•••this is equivalent to posix_fallocate except that it has an extra
mode/flags argument to control its behavior, and stores the error in
errno rather than returning an error code.

| * | add timerfd interfaces (untested) | Rich Felker | 2012-09-08 | 1 | -0/+18 |
| * | add stdnoreturn.h (C11)•••features.h contains the fallback logic for pre-C11 compilers
| Rich Felker | 2012-09-08 | 1 | -0/+5 |
| * | TCP_* is in the reserved namespace for tcp.h; make use of that | Rich Felker | 2012-09-07 | 1 | -3/+4 |
| * | remove unneeded judgemental commentary from ftw.h | Rich Felker | 2012-09-07 | 1 | -4/+0 |
| * | default features: make musl usable without feature test macros•••the old behavior of exposing nothing except plain ISO C can be
obtained by defining __STRICT_ANSI__ or using a compiler option (such
as -std=c99) that predefines it. the new default featureset is POSIX
with XSI plus _BSD_SOURCE. any explicit feature test macros will
inhibit the default.
installation docs have also been updated to reflect this change.

| * | provide loff_t for splice syscall•••so far, this is the only actual use of loff_t i've found. some
software, including glib, assumes loff_t must exist if splice exists;
this is a reasonable assumption since the official prototype for
splice uses loff_t, as it always works with 64-bit offsets regardless
of the selected libc off_t size. i'm using #define for now rather than
a typedef to make it easy to define in other headers if necessary
(like the LFS64 ugliness), but it may be necessary to add it to
alltypes.h eventually if other functions end up needing it.
| Rich Felker | 2012-09-06 | 1 | -0/+1 |
| * | further use of _Noreturn, for non-plain-C functions•••note that POSIX does not specify these functions as _Noreturn, because
POSIX is aligned with C99, not the new C11 standard. when POSIX is
eventually updated to C11, it will almost surely give these functions
the _Noreturn attribute. for now, the actual _Noreturn keyword is not
used anyway when compiling with a c99 compiler, which is what POSIX
requires; the GCC __attribute__ is used instead if it's available,
however.
in a few places, I've added infinite for loops at the end of _Noreturn
functions to silence compiler warnings. presumably
__buildin_unreachable could achieve the same thing, but it would only
work on newer GCCs and would not be portable. the loops should have
near-zero code size cost anyway.
like the previous _Noreturn commit, this one is based on patches
contributed by philomath.

| * | add _Noreturn function attribute, with fallback for pre-C11 GNUC | Rich Felker | 2012-09-06 | 2 | -5/+19 |
| * | dladdr should be available under _BSD_SOURCE as well as _GNU_SOURCE | Rich Felker | 2012-09-06 | 1 | -1/+1 |
| * | use restrict everywhere it's required by c99 and/or posix 2008•••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.
| Rich Felker | 2012-09-06 | 28 | -184/+353 |
| * | avoid "inline" in public headers for strict c89 compatibility•••while musl itself requires a c99 compiler, some applications insist on
being compiled with c89 compilers, and use of "inline" in the headers
was breaking them. much of this had been avoided already by just
skipping the inline keyword in pre-c99 compilers or modes, but this
new unified solution is cleaner and may/should result in better code
generation in the default gcc configuration.

| * | fix wrong type for poll.h nfds_t•••this should not break anything since the type should never be used
except as the argument type for poll.
| Rich Felker | 2012-09-01 | 1 | -1/+1 |
| * | dladdr support for dynamic linker (nonstandard extension)•••based on patches submitted by boris brezillon. this commit also fixes
the issue whereby the main application and libc don't have the address
ranges of their mappings stored, which was theoretically a problem for
RTLD_NEXT support in dlsym; it didn't actually matter because libc
never calls dlsym, and it seemed to be doing the right thing (by
chance) for symbols in the main program as well.

| * | implement "low hanging fruit" from C11•••based on Gregor's patch sent to the list. includes:
- stdalign.h
- removing gets in C11 mode
- adding aligned_alloc and adjusting other functions to use it
- adding 'x' flag to fopen for exclusive mode
| Rich Felker | 2012-08-25 | 3 | -0/+18 |
| * | add c11 quick_exit and at_quick_exit functions | Rich Felker | 2012-08-25 | 1 | -0/+2 |
| * | type exposure fixes in sys/sem.h | Rich Felker | 2012-08-24 | 1 | -2/+5 |
| * | stdio_ext.h needs to include stdio.h, at least to get FILE... | Rich Felker | 2012-08-24 | 1 | -0/+2 |
| * | fix missing uintXX_t in nameser.h | Rich Felker | 2012-08-24 | 1 | -0/+2 |
| * | fix dirent.h with _BSD_SOURCE | Rich Felker | 2012-08-24 | 1 | -0/+3 |
| * | improve headers to better deal with removed-in-posix-2008 features•••with this patch, setting _POSIX_SOURCE, or setting _POSIX_C_SOURCE or
_XOPEN_SOURCE to an old version, will bring back the interfaces that
were removed in POSIX 2008 - at least the ones i've covered so far,
which are gethostby*, usleep, and ualarm. if there are other functions
still in widespread use that were removed for which similar changes
would be beneficial, they can be added just like this.
| Rich Felker | 2012-08-15 | 2 | -13/+22 |
| * | add missing xattr functions•••not sure why these were originally omitted..
| Rich Felker | 2012-08-15 | 1 | -0/+3 |
| * | math: fix _BSD_SOURCE namespace in math.h | nsz | 2012-08-13 | 1 | -25/+26 |
| * | remove significandl•••this function never existed historically; since the float/double
functions it's based on are nonstandard and deprecated, there's really
no justification for its existence except that glibc has it. it can be
added back if there's ever really a need...
| Rich Felker | 2012-08-13 | 1 | -1/+0 |
| * | add significand[fl] math functions | Rich Felker | 2012-08-13 | 1 | -0/+4 |
| * | publicly expose getdents api under _BSD_SOURCE | Rich Felker | 2012-08-13 | 1 | -0/+7 |
| * | add bsd fgetln function•••optimized to avoid allocation and return lines directly out of the
stream buffer whenever possible.
| Rich Felker | 2012-08-11 | 1 | -0/+4 |
| * | fix socket.h on mips•••why does mips have to be gratuitously incompatible in every possible
imaginable way?
| Rich Felker | 2012-08-05 | 1 | -0/+3 |
| * | add ioperm/iopl syscalls•••based on patches by orc and Isaac Dunham, with some fixes. sys/io.h
exists and contains prototypes for these functions regardless of
whether the target arch has them; this is a bit unorthodox but I don't
think it will break anything. the function definitions do not exist
unless the appropriate SYS_* syscall number macro is defined, which
should make sure configure scripts looking for these functions don't
find them on other systems.
presently, sys/io.h does not have the inb/outb/etc. port io
macros/functions. I'd be surprised if ioperm/iopl are useful without
them, so they probably need to be added at some point in appropriate
bits/io.h files...

| * | add splice and vmsplice syscalls•••based on patches by orc and Isaac Dunham.
| Rich Felker | 2012-07-23 | 1 | -0/+12 |
| * | add extended attributes syscalls•••based on patch by orc and Isaac Dunham, with some fixes.
| Rich Felker | 2012-07-23 | 1 | -0/+27 |
| * | add pipe2 syscall•••based on patch by orc and Isaac Dunham, with some details fixed.

| * | fix namespace issue in prototypes in math.h | Rich Felker | 2012-07-22 | 1 | -2/+2 |
| * | fix wrong size for sigjmp_buf signal set array•••128 is the size in bytes, not longs.
| Rich Felker | 2012-07-22 | 1 | -1/+1 |
| * | fix typo in aio.h | Rich Felker | 2012-07-19 | 1 | -1/+1 |
| * | workaround another sendmsg kernel bug on 64-bit machines•••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.
| Rich Felker | 2012-07-12 | 1 | -7/+0 |
| * | fix redef of sigprocmask constants on mips•••this fix is easier than trying to reorder the header stuff
| Rich Felker | 2012-07-12 | 1 | -2/+0 |
| * | more mips bits-header fixes•••signal handling was very broken because of this
| Rich Felker | 2012-07-12 | 1 | -0/+2 |
| * | add prototypes for getw/putw | Rich Felker | 2012-07-04 | 1 | -0/+2 |
| * | jmp_buf overhaul fixing several issues•••on arm, the location of the saved-signal-mask flag and mask were off
by one between sigsetjmp and siglongjmp, causing incorrect behavior
restoring the signal mask. this is because the siglongjmp code assumed
an extra slot was in the non-sig jmp_buf for the flag, but arm did not
have this. now, the extra slot is removed for all archs since it was
useless.
also, arm eabi requires jmp_buf to have 8-byte alignment. we achieve
that using long long as the type rather than with non-portable gcc
attribute tags.
