| * | add prlimit syscall wrapper | Rich Felker | 2012-01-20 | 1 | -0/+2 |
| * | fix some details in ugly stuff that doesn't belong in libc•••patches by sh4rm4, presumably needed to make gdb or some similar junk
happy...
| Rich Felker | 2011-10-17 | 1 | -6/+6 |
| * | don't define wchar_t on c++•••it's a keyword in c++ (wtf). i'm not sure this is the cleanest
solution; it might be better to avoid ever defining __NEED_wchar_t on
c++. but in any case, this works for now.
| Rich Felker | 2011-10-15 | 3 | -0/+6 |
| * | fix fcntl O_* flags for arm•••no idea why these 4 are permuted and the rest are standard/generic
| Rich Felker | 2011-10-05 | 1 | -4/+4 |
| * | typo (copy 2) in arm reloc.h | Rich Felker | 2011-10-01 | 1 | -1/+1 |
| * | typo in arm reloc.h | Rich Felker | 2011-10-01 | 1 | -1/+1 |
| * | first attempt at arm dynamic linking | Rich Felker | 2011-10-01 | 1 | -0/+26 |
| * | "optimize" arm __pthread_self•••actually this is just to avoid gcc being stupid and refusing to inline
the function version, even when the size cost is essentially identical
whether it's inlined or not.
| Rich Felker | 2011-09-22 | 1 | -4/+1 |
| * | fix x86_64 user.h (previously was just a copy of i386) | Rich Felker | 2011-09-22 | 1 | -48/+13 |
| * | cleanup/debloat i386 user.h | Rich Felker | 2011-09-22 | 1 | -43/+11 |
| * | wrong __WORDSIZE in x86_64 header | Rich Felker | 2011-09-22 | 1 | -1/+1 |
| * | update syscalls with off_t arguments to handle argument alignment, if needed•••the arm syscall abi requires 64-bit arguments to be aligned on an even
register boundary. these new macros facilitate meeting the abi
requirement without imposing significant ugliness on the code.
| Rich Felker | 2011-09-21 | 3 | -3/+6 |
| * | fix the definition of struct statvfs to match lsb abi•••at the same time, make struct statfs match the traditional definition
and make it more useful, especially the fsid_t stuff.
| Rich Felker | 2011-09-19 | 3 | -44/+18 |
| * | cleanup redundancy in bits/signal.h versions | Rich Felker | 2011-09-19 | 3 | -372/+31 |
| * | fix the type of wchar_t on arm; support wchar_t varying with arch•••really wchar_t should never vary, but the ARM EABI defines it as an
unsigned 32-bit int instead of a signed one, and gcc follows this
nonsense. thus, to give a conformant environment, we have to follow
(otherwise L""[0] and L'\0' would be 0U rather than 0, but the
application would be unaware due to a mismatched definition for
WCHAR_MIN and WCHAR_MAX, and Bad Things could happen with respect to
signed/unsigned comparisons, promotions, etc.).
fortunately no rules are imposed by the C standard on the relationship
between wchar_t and wint_t, and WEOF has type wint_t, so we can still
make wint_t always-signed and use -1 for WEOF.

| * | fix incorrect long double parameters on arm (and other future ports)•••this was the cause of crashes in printf when attempting to print
floating point values.
| Rich Felker | 2011-09-19 | 1 | -10/+10 |
| * | initial commit of the arm port•••this port assumes eabi calling conventions, eabi linux syscall
convention, and presence of the kernel helpers at 0xffff0f?0 needed
for threads support. otherwise it makes very few assumptions, and the
code should work even on armv4 without thumb support, as well as on
systems with thumb interworking. the bits headers declare this a
little endian system, but as far as i can tell the code should work
equally well on big endian.
some small details are probably broken; so far, testing has been
limited to qemu/aboriginal linux.

| * | cleanup more bits cruft (sysmacros and socket) | Rich Felker | 2011-09-18 | 4 | -413/+0 |
| * | more bits junk (tcp.h) | Rich Felker | 2011-09-18 | 2 | -2/+0 |
| * | move invariant netinet/in.h stuff out of bits/in.h | Rich Felker | 2011-09-18 | 2 | -290/+0 |
| * | security hardening: ensure suid programs have valid stdin/out/err•••this behavior (opening fds 0-2 for a suid program) is explicitly
allowed (but not required) by POSIX to protect badly-written suid
programs from clobbering files they later open.
this commit does add some cost in startup code, but the availability
of auxv and the security flag will be useful elsewhere in the future.
in particular auxv is needed for static-linked vdso support, which is
still waiting to be committed (sorry nik!)

| * | typo in macro definitions for x86_64 | Rich Felker | 2011-08-14 | 1 | -1/+1 |
| * | ensure the compiler does not move around thread-register-based reads•••if gcc decided to move this across a conditional that checks validity
of the thread register, an invalid thread-register-based read could be
performed and raise sigsegv.
| Rich Felker | 2011-08-06 | 2 | -2/+2 |
| * | socket headers macro adjustment - workaround for buggy programs•••some program was undefining AF_NETLINK and thereby breaking AF_ROUTE...
| Rich Felker | 2011-07-21 | 2 | -2/+2 |
| * | fix some symbol resolution issues in dynamic linker•••1. search was wrongly beginning with lib itself rather than dso head
2. inconsistent resolution of function pointers for functions in plt
| Rich Felker | 2011-06-25 | 2 | -0/+2 |
| * | move all limits that don't vary out of bits/limits.h, into main limits.h | Rich Felker | 2011-06-25 | 2 | -53/+2 |
| * | proper path searching for dynamic linker•••first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from
/etc/ld-musl-$ARCH.path and fallback to a builtin default.
| Rich Felker | 2011-06-25 | 2 | -0/+4 |
| * | experimental dynamic linker!•••some notes:
- library search path is hard coded
- x86_64 code is untested and may not work
- dlopen/dlsym is not yet implemented
- relocations in read-only memory won't work
| Rich Felker | 2011-06-18 | 2 | -0/+54 |
| * | __syscall5 inline is having trouble with PIC; just use the function for now | Rich Felker | 2011-06-14 | 1 | -0/+7 |
| * | use __WCHAR_TYPE__ on i386 if it is defined•••unfortunately traditional i386 practice was to use "long" rather than
"int" for wchar_t, despite the latter being much more natural and
logical. we followed this practice, but it seems some compilers (clang
and maybe certain gcc builds or others too..?) have switched to using
int, resulting in spurious pointer type mismatches when L"..." wide
strings are used. the best solution I could find is to use the
compiler's definition of wchar_t if it exists, and otherwise fallback
to the traditional definition.
there's no point in duplicating this approach on 64-bit archs, as
their only 32-bit type is int.
| Rich Felker | 2011-06-07 | 1 | -0/+4 |
| * | use compiler builtins for variadic macros when available•••this slightly cuts down on the degree musl "fights with" gcc, but more
importantly, it fixes a critical bug when gcc inlines a variadic
function and optimizes out the variadic arguments due to noticing that
they were "not used" (by __builtin_va_arg).
we leave the old code in place if __GNUC__ >= 3 is false; it seems
like it might be necessary at least for tinycc support and perhaps if
anyone ever gets around to fixing gcc 2.95.3 enough to make it work..
| Rich Felker | 2011-04-27 | 2 | -1/+5 |
| * | add word-sized ctz function to atomic.h•••strictly speaking this and a few other ops should be factored into
asm.h or the file should just be renamed to asm.h, but whatever. clean
it up someday.
| Rich Felker | 2011-04-27 | 2 | -4/+16 |
| * | move wait.h macros out of bits. they do not vary. | Rich Felker | 2011-04-21 | 4 | -46/+0 |
| * | namespace fixes for sys/mman.h | Rich Felker | 2011-04-20 | 2 | -30/+30 |
| * | add syscall wrappers for posix_fadvise, posix_fallocate | Rich Felker | 2011-04-20 | 2 | -0/+6 |
| * | overhaul pthread cancellation•••this patch improves the correctness, simplicity, and size of
cancellation-related code. modulo any small errors, it should now be
completely conformant, safe, and resource-leak free.
the notion of entering and exiting cancellation-point context has been
completely eliminated and replaced with alternative syscall assembly
code for cancellable syscalls. the assembly is responsible for setting
up execution context information (stack pointer and address of the
syscall instruction) which the cancellation signal handler can use to
determine whether the interrupted code was in a cancellable state.
these changes eliminate race conditions in the previous generation of
cancellation handling code (whereby a cancellation request received
just prior to the syscall would not be processed, leaving the syscall
to block, potentially indefinitely), and remedy an issue where
non-cancellable syscalls made from signal handlers became cancellable
if the signal handler interrupted a cancellation point.
x86_64 asm is untested and may need a second try to get it right.

| * | fix O_SYNC definition, cleanup fcntl.h | Rich Felker | 2011-04-14 | 2 | -22/+10 |
| * | fix FAPPEND typo on x86_64 (previously only fixed on i386) | Rich Felker | 2011-04-14 | 1 | -1/+1 |
| * | fcntl.h: move macros that do not vary between archs out of bits | Rich Felker | 2011-04-14 | 2 | -48/+0 |
| * | fix broken fcntl locks on x86_64 | Rich Felker | 2011-04-14 | 1 | -3/+3 |
| * | fix typo in legacy FAPPEND definition | Rich Felker | 2011-04-14 | 1 | -1/+1 |
| * | numerous fixes to sysv ipc•••some of these definitions were just plain wrong, others based on
outdated ancient "non-64" versions of the kernel interface.
as much as possible has now been moved out of bits/*
these changes break abi (the old abi for these functions was wrong),
but since they were not working anyway it can hardly matter.
| Rich Felker | 2011-04-13 | 6 | -48/+36 |
| * | fix and cleanup suseconds_t/timeval stuff (broken on 64-bit)•••trash in the upper 32 bits was making the kernel sleep forever in
select on 64-bit systems.
| Rich Felker | 2011-04-13 | 1 | -1/+1 |
| * | more types cleanup•••the basic idea is that the only things in alltypes.h should be types
that either vary from system to system (in practice, not just in
theoretical la-la land - this is the implementation so we choose what
constraints we want to impose on ports) or which are needed by
multiple system headers.
| Rich Felker | 2011-04-11 | 2 | -6/+0 |
| * | cleanup types stuff in headers, fix missing u_int*_t in sys/types.h | Rich Felker | 2011-04-11 | 2 | -22/+0 |
| * | add missing float.h macros•••actually FLT_ROUNDS needs to expand to a static inline function that
obtains the current rounding mode and returns it, but that will be
added later with fenv.h stuff.
| Rich Felker | 2011-04-10 | 2 | -0/+6 |
| * | workaround broken msghdr struct on 64bit linux•••POSIX clearly specifies the type of msg_iovlen and msg_controllen, and
Linux ignores it and makes them both size_t instead. to work around
this we add padding (instead of just using the wrong types like glibc
does), but we also need to patch-up the struct before passing it to
the kernel in case the caller did not zero-fill it.
if i could trust the kernel to just ignore the upper 32 bits, this
would not be necessary, but i don't think it will ignore them...
| Rich Felker | 2011-04-08 | 1 | -2/+2 |
| * | add ip6 pktinfo stuff for x86_64•••these defs should probably all be moved out of bits and unified...
| Rich Felker | 2011-04-05 | 1 | -0/+12 |
| * | add some missing ipv6 stuff | Rich Felker | 2011-04-05 | 1 | -0/+12 |
| * | uncomment IP_PKTINFO•••this was a hack leftover from testing before the initial
check-in to git.
