| * | fix stale pointer issue in dynamic linker with dlopen | Rich Felker | 2011-06-26 | 1 | -0/+1 |
| * | don't leave the lock held on dlopen failure.. | Rich Felker | 2011-06-26 | 1 | -2/+2 |
| * | add RTLD_DEFAULT support | Rich Felker | 2011-06-26 | 1 | -1/+2 |
| * | in dlopen: don't use null pointer•••deps can be null if a library has no dependencies (such as libc itself)
| Rich Felker | 2011-06-26 | 1 | -3/+3 |
| * | fix resolving symbols in objects loaded in RTLD_LOCAL mode•••basically we temporarily make the library and all its dependencies
part of the global namespace but only for the duration of performing
relocations, then return them to their former state.
| Rich Felker | 2011-06-26 | 1 | -0/+11 |
| * | experimental dlopen/dlsym and dynlink changes needed to support them | Rich Felker | 2011-06-26 | 1 | -8/+125 |
| * | type directives for x86_64 math asm | Rich Felker | 2011-06-26 | 2 | -0/+2 |
| * | error handling in dynamic linking•••some of the code is not yet used, and is in preparation for dlopen
which needs to be able to handle failure loading libraries without
terminating the program.
| Rich Felker | 2011-06-26 | 1 | -2/+19 |
| * | fix useless use of potentially-uninitialized mode variable in sem_open | Rich Felker | 2011-06-26 | 1 | -1/+1 |
| * | eliminate OOB array hacks in malloc | Rich Felker | 2011-06-26 | 1 | -46/+45 |
| * | use .type directives for math asm (needed for dynamic linking to work) | Rich Felker | 2011-06-26 | 15 | -0/+26 |
| * | 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 | 1 | -4/+4 |
| * | wordexp cannot use we_offs unless WRDE_DOOFFS flag is set•••previously, a potentially-indeterminate value from we_offs was being
used, resulting in wrong we_wordc and subsequent crashes in the
caller.

| * | XSI search.h API implementation by Szabolcs Nagy | Rich Felker | 2011-06-25 | 4 | -0/+352 |
| * | handle library paths better (ignore empty path components, etc.) | Rich Felker | 2011-06-25 | 1 | -3/+5 |
| * | fix possible (questionable) strict aliasing violations and ptr arith | Rich Felker | 2011-06-25 | 1 | -3/+3 |
| * | const correctness in mq_notify•••why did gcc allow this invalid assignment to compile in the first place?
| Rich Felker | 2011-06-25 | 1 | -1/+1 |
| * | 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 | 1 | -14/+38 |
| * | optimize opendir using O_CLOEXEC | Rich Felker | 2011-06-25 | 1 | -2/+1 |
| * | discard dso descriptors after performing relocations•••eventually (once dlopen exists) this behavior will be conditional on
dlopen/dlsym not being reachable.
| Rich Felker | 2011-06-25 | 1 | -0/+12 |
| * | keep track of which dsos have been relocated | Rich Felker | 2011-06-25 | 1 | -0/+1 |
| * | prepare support for LD_LIBRARY_PATH (checking suid/sgid safety)•••the use of this test will be much stricter than glibc and other
typical implementations; the environment will not be honored
whatsoever unless the program is confirmed non-suid/sgid by the aux
vector the kernel passed in. no fallback to slow syscall-based
checking is used if the kernel fails to provide the information; we
simply assume the worst (suid) in this case and refuse to honor
environment.

| * | initial commit of prng implementation by Szabolcs Nagy | Rich Felker | 2011-06-23 | 2 | -12/+107 |
| * | make ldso asm more uniform with rest of codebase (no unnecessary suffixes) | Rich Felker | 2011-06-19 | 1 | -12/+12 |
| * | x86_64: ensure that dtor pointer passed to app is 0 so it won't be used•••leaving it uninitialized caused unpredictable crashes or worse due to
calling an indeterminate function pointer.
| Rich Felker | 2011-06-19 | 1 | -0/+1 |
| * | dynamic linker 64bit fix: hash table entries are always 32bit | Rich Felker | 2011-06-18 | 1 | -2/+2 |
| * | 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 | 3 | -0/+412 |
| * | fix memory leak on failure in realpath | Rich Felker | 2011-06-18 | 1 | -4/+4 |
| * | duplicate re_nsub in LSB/glibc ABI compatible location | Rich Felker | 2011-06-16 | 1 | -1/+1 |
| * | restore use of .type in asm, but use modern @function (vs %function)•••this seems to be necessary to make the linker accept the functions in
a shared library (perhaps to generate PLT entries?)
strictly speaking libc-internal asm should not need it. i might clean
that up later.
| Rich Felker | 2011-06-14 | 20 | -0/+29 |
| * | fix race condition in pthread_kill•••if thread id was reused by the kernel between the time pthread_kill
read it from the userspace pthread_t object and the time of the tgkill
syscall, a signal could be sent to the wrong thread. the tgkill
syscall was supposed to prevent this race (versus the old tkill
syscall) but it can't; it can only help in the case where the tid is
reused in a different process, but not when the tid is reused in the
same process.
the only solution i can see is an extra lock to prevent threads from
exiting while another thread is trying to pthread_kill them. it should
be very very cheap in the non-contended case.
| Rich Felker | 2011-06-14 | 3 | -1/+8 |
| * | run dtors before taking the exit-lock in pthread exit•••previously a long-running dtor could cause pthread_detach to block.
| Rich Felker | 2011-06-14 | 1 | -2/+2 |
| * | minor locking optimizations | Rich Felker | 2011-06-14 | 2 | -2/+2 |
| * | avoid 64bit warnings when using pointers as entropy for temp names | Rich Felker | 2011-06-13 | 2 | -2/+4 |
| * | fix sigset macro for 64-bit systems (<< was overflowing due to wrong type) | Rich Felker | 2011-06-13 | 1 | -1/+1 |
| * | remove all .size and .type directives for functions from the asm•••these are useless and have caused problems for users trying to build
with non-gnu tools like tcc's assembler.
| Rich Felker | 2011-06-13 | 18 | -52/+0 |
| * | remove old useless timezone.s file (unused) | Rich Felker | 2011-06-13 | 1 | -27/+0 |
| * | fix wrong type for wcsrchr argument 2 | Rich Felker | 2011-06-13 | 1 | -1/+1 |
| * | x86_64 fenv support (untested; at least known to build successfully) | Rich Felker | 2011-06-13 | 1 | -0/+88 |
| * | fix fesetround - it was writing to status word instead of control word | Rich Felker | 2011-06-13 | 1 | -3/+8 |
| * | floating point environment, untested•••at present the i386 code does not support sse floating point, which is
not part of the standard i386 abi. while it may be desirable to
support it later, doing so will reduce performance and require some
tricks to probe if sse support is present.
this first commit is i386-only, but it should be trivial to port the
asm to x86_64.
| Rich Felker | 2011-06-12 | 6 | -0/+144 |
| * | malloc: cast size down to int in bin_index functions•••even if size_t was 32-bit already, the fact that the value was
unsigned and that gcc is too stupid to figure out it would be positive
as a signed quantity (due to the immediately-prior arithmetic and
conditionals) results in gcc compiling the integer-to-float conversion
as zero extension to 64 bits followed by an "fildll" (64 bit)
instruction rather than a simple "fildl" (32 bit) instruction on x86.
reportedly fildll is very slow on certain p4-class machines; even if
not, the new code is slightly smaller.

| * | another return value fix for mktemp... | Rich Felker | 2011-06-12 | 1 | -1/+2 |
| * | it's called getgrgid_r, not getgruid_r... | Rich Felker | 2011-06-08 | 1 | -1/+1 |
| * | implement psignal and psiginfo | Rich Felker | 2011-06-08 | 2 | -0/+20 |
| * | mq names without leading / have impl-def behavior; allowing them is easier | Rich Felker | 2011-06-07 | 2 | -9/+2 |
| * | define MQ_PRIO_MAX | Rich Felker | 2011-06-07 | 1 | -1/+1 |
| * | mq send/recv functions are cancellation points | Rich Felker | 2011-06-07 | 2 | -2/+2 |
| * | implement mq_notify | Rich Felker | 2011-06-07 | 1 | -2/+65 |
| * | add support for POSIX message queues, except mq_notify | Rich Felker | 2011-06-07 | 10 | -0/+99 |
