| 2014-03-05 | fix strerror on mips: one error code is out of the 8-bit table range•••if we ever encounter other targets where error codes don't fit in the
8-bit range, the table should probably just be bumped to 16-bit, but
for now I don't want to increase the table size on all archs just
because of a bug in the mips abi.

| 2014-02-28 | improve configure's target arch matching•••most notably, it was failing to match sh4-*, etc., but in general the
explicit matching of hyphens for some archs was problematic because it
failed to accept simply the musl-style arch name (without a gcc-style
tuple) as an input. the original motivation of matching hyphens was to
prevent incorrectly identifying a 64-bit arch as the corresponding
32-bit arch (e.g. mips* matching mips64) but this is easily fixed by
simply checking (and for now, rejecting as unsupported) the relevant
64-bit archs.

| 2014-02-27 | fix endian subarchs for sh arch•••default endianness for sh on linux is little, and while conventions
vary, "eb" seems to be the most widely used suffix for big endian.

| 2014-02-27 | rename superh port to "sh" for consistency•••linux, gcc, etc. all use "sh" as the name for the superh arch. there
was already some inconsistency internally in musl: the dynamic linker
was searching for "ld-musl-sh.path" as its path file despite its own
name being "ld-musl-superh.so.1". there was some sentiment in both
directions as to how to resolve the inconsistency, but overall "sh"
was favored.

| 2014-02-25 | fix readdir not to set ENOENT when directory is removed while reading•••per POSIX, ENOENT is reserved for invalid stream position; it is an
optional error and would only happen if the application performs
invalid seeks on the underlying file descriptor. however, linux's
getdents syscall also returns ENOENT if the directory was removed
between the time it was opened and the time of the read. we need to
catch this case and remap it to simple end-of-file condition (null
pointer return value like an error, but no change to errno). this
issue reportedly affects GNU make in certain corner cases.
rather than backing up and restoring errno, I've just changed the
syscall to be made in a way that doesn't affect errno (via an inline
syscall rather than a call to the __getdents function). the latter
still exists for the purpose of providing the public getdents alias
which sets errno.

| 2014-02-24 | add missing sub files for mipsel-sf to use softfloat code•••the build system has no automatic way to know this code applies to
both big (default) and little endian variants, so explicit .sub files
are needed.
| Rich Felker | 3 | -0/+3 |
| 2014-02-24 | mips: add mips-sf subarch support (soft-float)•••Userspace emulated floating-point (gcc -msoft-float) is not compatible
with the default mips abi (assumes an FPU or in kernel emulation of it).
Soft vs hard float abi should not be mixed, __mips_soft_float is checked
in musl's configure script and there is no runtime check. The -sf subarch
does not save/restore floating-point registers in setjmp/longjmp and only
provides dummy fenv implementation.

| 2014-02-24 | fixup general __syscall breakage introduced in x32 port•••the reordering of headers caused some risc archs to not see
the __syscall declaration anymore.
this caused build errors on mips with any compiler,
and on arm and microblaze with clang.
we now declare it locally just like the powerpc port does.
| rofl0r | 3 | -0/+6 |
| 2014-02-23 | make the x32 port use the correct ld-musl-x32.path filename•••previously it was wrongly using the x86_64 one, precluding having both
x32 and x86_64 libs present on the same system.

| 2014-02-23 | fix x32 syscall arch.h timespec fixup code•••it's legal to call the __syscall functions with more arguments than
necessary, and the __syscall_cp cancel dummy impl. does just that.
thus we must insert the switch for all possible syscalls numbers
into all of the syscallN inline functions.
| rofl0r | 1 | -53/+49 |
| 2014-02-23 | fix some issues in x32 syscall_cp_fixup•••- the nanosleep fixup "fixed" the second timespec* argument erroneusly.
- the futex fixup was missing the check for FUTEX_WAIT.
- general cleanup using a macro.

| 2014-02-23 | configure: suppress bogus pointer-int cast warnings | rofl0r | 1 | -0/+1 |
| 2014-02-23 | configure: recognize x86_64-x32 and x32•••x32 is the internal arch name, but glibc uses x86_64-x32.
there doesn't exist a specific triple for x32 in gcc and binutils.
you're supposed to build your compiler for x86_64 and configure
it with multilib support for "mx32".
however it turns out that using a triple of x86_64-x32 makes
gcc and binutils pick up the right arch (they detect it as x86_64)
and allows us to have a unique triple for cross-compiler toolchains.

| 2014-02-22 | 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 | 1 | -8/+8 |
| 2014-02-22 | use syscall_arg_t type for syscall prototypes in pthread code | rofl0r | 2 | -3/+8 |
| 2014-02-22 | internal/syscall.h: add syscall_arg_t macro•••some 32-on-64 archs require that the actual syscall args be long long.
in that case syscall_arch.h can define syscall_arg_t to whatever it needs
and syscall.h picks it up.
all other archs just use long as usual.
| rofl0r | 1 | -6/+11 |
| 2014-02-22 | internal/syscall.h: use a macro for the syscall args casts•••this allows syscall_arch.h to define the macro __scc if special
casting is needed, as is the case for x32, where the actual syscall
arguments are 64bit, but, in case of pointers, would get sign-extended
and thus become invalid.
| rofl0r | 1 | -13/+17 |
| 2014-02-21 | add fallback emulation for accept4 on old kernels•••the other atomic FD_CLOEXEC interfaces (dup3, pipe2, socket) already
had such emulation in place. the justification for doing the emulation
here is the same as for the other functions: it allows applications to
simply use accept4 rather than having to have their own fallback code
for ENOSYS/EINVAL (which one you get is arch-specific!) and there is
no reasonable way an application could benefit from knowing the
operation is emulated/non-atomic since there is no workaround at the
application level for non-atomicity (that is the whole reason these
interfaces were added).
| Rich Felker | 1 | -1/+12 |
| 2014-02-18 | add flock64 alias for (struct) flock in fcntl.h•••this was a missing part of the LFS64 API; it's "needed" for use with
fcntl and the corresponding lock commands.

| 2014-02-13 | add ipv6 and icmpv6 to getprotoent-family functions•••based on patch by orc.
| Rich Felker | 1 | -1/+3 |
| 2014-02-13 | fix typo in table for getprotoent that caused out-of-bound reads•••this was unlikely to lead to any crash or dangerous behavior, but
caused adjacent string constants to be treated as part of the
protocols table, possibly returning nonsensical results for unknown
protocol names/numbers or when getprotoent was called in a loop to
enumerate all protocols.
| Rich Felker | 1 | -1/+1 |
| 2014-02-12 | make posix_spawn accept null pid pointer arguments•••this is a requirement in the specification that was overlooked.

| 2014-02-11 | add parens when bit and arith ops are mixed in macros in public headers•••another commit to silence gcc warnings (-Wparentheses) for standard headers.
changed macros: LOG_UPTO, IN6_ARE_ADDR_EQUAL
| Szabolcs Nagy | 2 | -2/+2 |
| 2014-02-11 | 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 | 3 | -3/+3 |
| 2014-02-09 | clone: make clone a wrapper around __clone•••The architecture-specific assembly versions of clone did not set errno on
failure, which is inconsistent with glibc. __clone still returns the error
via its return value, and clone is now a wrapper that sets errno as needed.
The public clone has also been moved to src/linux, as it's not directly
related to the pthreads API.
__clone is called by pthread_create, which does not report errors via
errno. Though not strictly necessary, it's nice to avoid clobbering errno
here.

| 2014-02-09 | fix fesetenv(FE_DFL_ENV) on x86_64 (see previous commit) | Szabolcs Nagy | 1 | -1/+1 |
| 2014-02-09 | fix fesetenv(FE_DFL_ENV) on i386•••the default fenv was not set up properly, in particular the
tag word that indicates the contents of the x87 registers was
set to 0 (used) instead of 0xffff (empty)
this could cause random crashes after setting the default fenv
because it corrupted the fpu stack and then any float computation
gives NaN result breaking the program logic (usually after a
float to integer conversion).
| Szabolcs Nagy | 1 | -1/+1 |
| 2014-02-07 | in fdopen, avoid setting O_APPEND flag if it's already set•••this saves a syscall in the case where the underlying open already
took place with O_APPEND, which is common because fopen with append
modes sets O_APPEND at the time of open before passing the file
descriptor to __fdopen.
| Rich Felker | 1 | -1/+2 |
| 2014-02-07 | fix ftello result for append streams with unflushed output•••when there is unflushed output, ftello (and ftell) compute the logical
stream position as the underlying file descriptor's offset plus an
adjustment for the amount of buffered data. however, this can give the
wrong result for append-mode streams where the unflushed writes should
adjust the logical position to be at the end of the file, as if a seek
to end-of-file takes place before the write.
the solution turns out to be a simple trick: when ftello (indirectly)
calls lseek to determine the current file offset, use SEEK_END instead
of SEEK_CUR if the stream is append-mode and there's unwritten
buffered data.
the ISO C rules regarding switching between reading and writing for a
stream opened in an update mode, along with the POSIX rules regarding
switching "active handles", conveniently leave undefined the
hypothetical usage cases where this fix might lead to observably
incorrect offsets.
the bug being fixed was discovered via the test case for glibc issue

| 2014-02-05 | reduce namespace pollution in netinet/udp.h•••the affected part of the header is responsible for providing both GNU
and BSD versions of the udphdr structure. previously, the
namespace-polluting GNU names were always used for the actual struct
members, and the BSD names, which are named in a manner resembling a
sane namespace, were always macros defined to expand to the GNU names.
now, unless _GNU_SOURCE is defined, the BSD names are used as the
actual structure members, and the macros and GNU names only come into
play when the application requests them.
| Rich Felker | 1 | -7/+10 |
| 2014-02-05 | fix use of legacy u_intN_t types in netinet/tcp.h•••policy is to avoid using these types except where they are needed for
namespace conformance. C99-style stdint.h types should be used
instead.
| Rich Felker | 1 | -73/+74 |
| 2014-02-05 | add support for BSD struct tcphdr in netinet/tcp.h•••there are two versions of this structure: the BSD version and the GNU
version. previously only the GNU version was supported. the only way
to support both simultaneously is with an anonymous union, which was a
nonstandard extension prior to C11, so some effort is made to avoid
breakage with compilers which do not support anonymous unions.
this commit is based on a patch by Timo Teräs, but with some changes.
in particular, the GNU version of the structure is not exposed unless
_GNU_SOURCE is defined; this both avoids namespace pollution and
dependency on anonymous unions in the default feature profile.
| Rich Felker | 1 | -4/+41 |
| 2014-02-05 | 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 | 1 | -0/+11 |
| 2014-02-05 | add NO_ADDRESS macro to netdb.h as an alias for NO_DATA•••some applications expect it to be defined, despite the standard making
it impossible for it to ever be returned as a value distinct from
NO_DATA. since these macros are outside the scope of the current
standards, no special effort is made to hide NO_ADDRESS under
conditions where the others are exposed.

| 2014-02-01 | fix nftw FTW_MOUNT flag•••the incorrect check for crossing device boundaries was preventing nftw
from traversing anything except the initially provided pathname.
