| * | fix bug dlsym bug that slipped in during dynamic linker cleanup | Rich Felker | 2012-08-07 | 1 | -1/+1 |

| * | dlsym RTLD_NEXT support for mips•••untested
| Rich Felker | 2012-08-05 | 1 | -0/+15 |
| * | fix socket.h on mips•••why does mips have to be gratuitously incompatible in every possible
imaginable way?
| Rich Felker | 2012-08-05 | 2 | -0/+6 |
| * | align mips _init/_fini functions•••since .init and .fini are not .text, the toolchain does not seem to
align them for code by default. this yields random breakage depending
on the object sizes the linker is dealing with.

| * | more changes that were lost when committing mips dynamic linker | Rich Felker | 2012-08-05 | 1 | -0/+4 |
| * | more stuff lost committing mips dynamic linker | Rich Felker | 2012-08-05 | 1 | -2/+2 |
| * | fix change lost in the process of integrating mips dynamic linker | Rich Felker | 2012-08-05 | 1 | -2/+2 |
| * | remove configure check disabling shared libraries on mips | Rich Felker | 2012-08-05 | 1 | -4/+0 |
| * | mips dynamic linker support•••not heavily tested, but the basics are working. the basic concept is
that the dynamic linker entry point code invokes a pure-PIC (no global
accesses) C function in reloc.h to perform the early GOT relocations
needed to make the dynamic linker itself functional, then invokes
__dynlink like on other archs. since mips uses some ugly arch-specific
hacks to optimize relocating the GOT (rather than just using the
normal DT_REL[A] tables like on other archs), the dynamic linker has
been modified slightly to support calling arch-specific relocation
code in reloc.h.
most of the actual mips-specific behavior was developed by reading the
output of readelf on libc.so and simple executable files. i could not
find good reference information on which relocation types need to be
supported or their semantics, so it's possible that some legitimate
usage cases will not work yet.
| Rich Felker | 2012-08-05 | 3 | -3/+102 |
| * | make dynlink.lo depend on reloc.h in makefile•••this is mainly a development convenience but will also ensure users
building from latest git always get up-to-date arch-specific dynamic
linker code without having to "make clean".
| Rich Felker | 2012-08-05 | 1 | -0/+2 |
| * | more cleanup of dynamic linker internals | Rich Felker | 2012-08-05 | 1 | -8/+9 |
| * | more dynamic linker internals cleanup•••changing the string printed for the dso name is not a regression; the
old code was simply using the wrong dso name (head rather than the dso
currently being relocated). this will be fixed in a later commit.

| * | dynamic linker internals cleanup | Rich Felker | 2012-08-05 | 1 | -5/+7 |
| * | floating point support for arm setjmp/longjmp•••not heavily tested, but at least they don't seem to break anything on
soft float targets with or without coprocessors. they check the auxv
AT_HWCAP flags to determine which coprocessor, if any, is available.
| Rich Felker | 2012-08-05 | 2 | -2/+54 |
| * | release notes for 0.9.3 | Rich Felker | 2012-08-02 | 1 | -0/+35 |
| * | abstract out compiler runtime library for linking libc.so•••this allows config.mak to override the default -lgcc for building with
other compilers such as pcc/clang/etc.
| Rich Felker | 2012-08-02 | 1 | -1/+2 |
| * | fix argument type error on wcwidth function•••since the correct declaration was not visible, and since the
representation of the types wchar_t and wint_t always match, a
compiler would have to go out of its way to make this bug manifest,
but better to fix it anyway.
| Rich Felker | 2012-08-02 | 1 | -2/+2 |
| * | fix missing static in getusershell (namespace pollution) | Rich Felker | 2012-08-02 | 1 | -1/+1 |
| * | optimize mempcpy to minimize need for data saved across the call | Rich Felker | 2012-07-31 | 1 | -2/+1 |
| * | optimize arm setjmp/longjmp register saving/loading•••the original code was wrongly based on how it would be done in thumb
mode, but that's not needed because musl's asm only targets arm.
| Rich Felker | 2012-07-27 | 2 | -6/+2 |
| * | save AT_HWCAP from auxv for subsequent use in machine-specific code•••it's expected that this will be needed/useful only in asm, so I've
given it its own symbol that can be addressed in pc-relative ways from
asm rather than adding a field in the __libc structure which would
require hard-coding the offset wherever it's used.
| Rich Felker | 2012-07-27 | 3 | -0/+4 |
| * | retry on cas failures in sem_trywait•••this seems counter-intuitive since sem_trywait is supposed to just try
once, not wait for the semaphore. however, the retry loop is not a
wait. instead, it's to handle the case where the value changes due to
a simultaneous post or wait from another thread while the semaphore
value remains positive. in such a case, it's absolutely wrong for
sem_trywait to fail with EAGAIN because the semaphore is not busy.
| Rich Felker | 2012-07-24 | 1 | -2/+2 |
| * | gcc wrapper improvement: leave libgcc dir in the library path•••this is needed in case -lgcc is passed explicitly on the link command
line, for example if the wrapper is being used to build musl itself.
| Rich Felker | 2012-07-23 | 1 | -1/+1 |
| * | 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 | 3 | -0/+28 |
| * | add extended attributes syscalls•••based on patch by orc and Isaac Dunham, with some fixes.
| Rich Felker | 2012-07-23 | 2 | -0/+74 |
| * | add pipe2 syscall•••based on patch by orc and Isaac Dunham, with some details fixed.
| Rich Felker | 2012-07-23 | 2 | -0/+9 |
| * | remove scanf dependency from getaddrinfo /etc/services support | Rich Felker | 2012-07-22 | 1 | -5/+4 |
| * | getaddrinfo /etc/services lookup support | Rich Felker | 2012-07-22 | 1 | -3/+16 |
| * | 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 |
| * | add floating point register saving/restoring to mips setjmp/longjmp•••also fix the alignment of jmp_buf to meet the abi. linux always
emulates fpu on mips if it's not present, so enabling this code
unconditionally is "safe" but may be slow. in the long term it may be
preferable to find a way to disable it on soft float builds.
| Rich Felker | 2012-07-22 | 3 | -2/+30 |
| * | make getservby*_r return error code rather than -1 (and using errno)•••untested but should be correct..
| Rich Felker | 2012-07-22 | 2 | -19/+35 |
| * | fix logic error for skipping failed interfaces in if_nameindex | Rich Felker | 2012-07-21 | 1 | -8/+7 |
| * | fix typo in aio.h | Rich Felker | 2012-07-19 | 1 | -1/+1 |
| * | fix getservby*() with null pointer for protocol argument•••not sure this is the best fix but it should work
| Rich Felker | 2012-07-14 | 2 | -0/+8 |
| * | avoid blx instruction which does not exist on armv4t or armv4 | Rich Felker | 2012-07-14 | 1 | -1/+2 |
| * | make dynamic linker tell the debugger its own pathname•••use the main program's PT_INTERP header if possible, since this is
sure to be a correct (and hopefully absolute) pathname.
| Rich Felker | 2012-07-13 | 1 | -0/+5 |
| * | fix broken mips a_fetch_add•••sc was overwriting the result
| Rich Felker | 2012-07-12 | 1 | -7/+7 |
| * | sigsetjmp asm for mips | Rich Felker | 2012-07-12 | 1 | -0/+27 |
| * | mipsel (little endian) support•••the fields in the mcontext_t are long long (for no good reason) even
on 32-bit mips, so the offset of the instruction pointer (as a word)
varies depending on endianness.
| Rich Felker | 2012-07-12 | 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 | 6 | -7/+42 |
| * | fix redef of sigprocmask constants on mips•••this fix is easier than trying to reorder the header stuff
| Rich Felker | 2012-07-12 | 2 | -2/+3 |
| * | disable dynamic linking on mips for now (broken) | Rich Felker | 2012-07-12 | 1 | -0/+5 |
| * | more mips bits-header fixes•••signal handling was very broken because of this
| Rich Felker | 2012-07-12 | 2 | -2/+8 |
| * | fix mips syscalls with long long args•••like arm, mips requires 64-bit arguments to be "aligned" on an even
register boundary.
| Rich Felker | 2012-07-12 | 1 | -1/+1 |
| * | fix several locks that weren't updated right for new futex-based __lock•••these could have caused memory corruption due to invalid accesses to
the next field. all should be fixed now; I found the errors with fgrep
-r '__lock(&', which is bogus since the argument should be an array.
| Rich Felker | 2012-07-12 | 4 | -10/+10 |
| * | fix pthread_kill unlocking•••it had not been updated for the futex-based locks
| Rich Felker | 2012-07-12 | 1 | -1/+1 |
