| 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.

| 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 | superh port | Bobby Bingham | 46 | -0/+2350 |
| 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.

| 2014-02-23 | x32 port (diff against vanilla x86_64) | rofl0r | 39 | -793/+882 |
| 2014-02-23 | import vanilla x86_64 code as x32 | rofl0r | 75 | -0/+2677 |
| 2014-02-23 | sys/shm.h: move arch specific structs to bits/ | rofl0r | 7 | -16/+73 |
| 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.
| Rich Felker | 1 | -0/+1 |
| 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.
| Rich Felker | 1 | -1/+1 |
| 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.

| 2014-02-05 | add legacy functions setkey() and encrypt() | Timo Teräs | 2 | -6/+66 |
| 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.
| Rich Felker | 1 | -2/+1 |
| 2014-01-23 | fix an overflow in wcsxfrm when n==0•••posix allows zero length destination
| Szabolcs Nagy | 1 | -2/+4 |
| 2014-01-21 | add version.h to .gitignore; it is a generated file | Rich Felker | 1 | -0/+1 |
| 2014-01-21 | fix crash in dynamic linker when certain copy relocations are unsatisfied•••STB_WEAK is only a weak reference for undefined symbols (those with a
section of SHN_UNDEF). otherwise, it's a weak definition. normally
this distinction would not matter, since a relocation referencing a
symbol that also provides a definition (not SHN_UNDEF) will always
succeed in finding the referenced symbol itself. however, in the case
of copy relocations, the referenced symbol itself is ignored in order
to search for another symbol to copy from, and thus it's possible that
no definition is found. in this case, if the symbol being resolved
happened to be a weak definition, it was misinterpreted as a weak
reference, suppressing the error path and causing a crash when the
copy relocation was performed with a null source pointer passed to
memcpy.
there are almost certainly still situations in which invalid
combinations of symbol and relocation types can cause the dynamic
linker to crash (this is pretty much inevitable), but the intent is
that crashes not be possible for symbol/relocation tables produced by
a valid linker.

| 2014-01-21 | fix initstate to make the state buffer usable in setstate•••setstate could use the results of previous initstate or setstate
calls (they return the old state buffer), but the documentation
requires that an initialized state buffer should be possible to
use in setstate immediately, which means that initstate should
save the generator parameters in it.
I also removed the copyright notice since it is present in the
copyright file.
| Szabolcs Nagy | 1 | -12/+2 |
| 2014-01-15 | fix system breakage window during make install due to permissions•••install.sh was wrongly waiting until after atomically replacing the
old file to set the correct permissions on the new file. in the case
of the dynamic linker, this would cause a dynamic-linked chmod command
not to run (due to missing executable permissions on the dynamic
linker) and thus leave the system in an unusable state.
even if chmod is static-linked, the old behavior had a race window
where dynamic-linked programs could fail to run.

| 2014-01-15 | remove more unnecessary operand-size suffixes from x86_64 atomic.h | Rich Felker | 1 | -3/+3 |
| 2014-01-11 | remove gratuitous temp vars, casts, and suffixes in x86_64 atomic.h•••aside from general cleanup, this should allow the identical atomic.h
file to be used for the upcoming x32 port.
| Rich Felker | 1 | -13/+11 |
| 2014-01-11 | remove size suffix in x86_64 __pthread_self asm•••the operand size is unnecessary, since the assembler knows it from the
destination register size. removing the suffix makes it so the same
code should work for x32.
| Rich Felker | 1 | -1/+1 |
| 2014-01-11 | make type of st_dev explicitly dev_t in x86_64 stat.h•••otherwise it's unclear that it's correct. aside from that, it makes
for a gratuitous difference between the x86_64 header and the upcoming
x32 header.
| Rich Felker | 1 | -1/+1 |
| 2014-01-08 | 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.

| 2014-01-08 | fix namespace violations in utmpx.h | Rich Felker | 2 | -5/+12 |
| 2014-01-08 | add IUTF8 to termios.h on archs that were missing it | Rich Felker | 4 | -0/+4 |
| 2014-01-08 | fix namespace violations in termios.h, at least mostly•••the fix should be complete on archs that use the generic definitions
(i386, arm, x86_64, microblaze), but mips and powerpc have not been
checked thoroughly and may need more fixes.
| Rich Felker | 6 | -52/+49 |
| 2014-01-08 | 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.

| 2014-01-08 | add __isoc99_vfscanf weak alias to vfscanf•••this glibc abi compatibility function was missed when the scanf
aliases were added.
