* fix dynamic linker issue in musl-gcc wrapperRich Felker2011-06-251-1/+1
|
* wordexp cannot use we_offs unless WRDE_DOOFFS flag is setRich Felker2011-06-251-1/+2
| | | | | | 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 NagyRich Felker2011-06-256-4/+392
|
* handle library paths better (ignore empty path components, etc.)Rich Felker2011-06-251-3/+5
|
* move all limits that don't vary out of bits/limits.h, into main limits.hRich Felker2011-06-253-53/+24
|
* fix possible (questionable) strict aliasing violations and ptr arithRich Felker2011-06-251-3/+3
|
* const correctness in mq_notifyRich Felker2011-06-251-1/+1
| | | | why did gcc allow this invalid assignment to compile in the first place?
* proper path searching for dynamic linkerRich Felker2011-06-253-14/+42
| | | | | first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from /etc/ld-musl-$ARCH.path and fallback to a builtin default.
* optimize opendir using O_CLOEXECRich Felker2011-06-251-2/+1
|
* discard dso descriptors after performing relocationsRich Felker2011-06-251-0/+12
| | | | | eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.
* keep track of which dsos have been relocatedRich Felker2011-06-251-0/+1
|
* use soname in ld-musl.so to prevent filename appearing in DT_NEEDEDsRich Felker2011-06-241-1/+1
|
* use symlink rather than bogus linker script for libc.soRich Felker2011-06-241-2/+2
| | | | the linker script caused a bogus DT_NEEDED entry
* adapt build/install/gcc-wrapper systems for dynamic linking supportRich Felker2011-06-233-9/+20
|
* prepare support for LD_LIBRARY_PATH (checking suid/sgid safety)Rich Felker2011-06-231-0/+6
| | | | | | | | | | 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 NagyRich Felker2011-06-233-12/+111
|
* make ldso asm more uniform with rest of codebase (no unnecessary suffixes)Rich Felker2011-06-191-12/+12
|
* x86_64: ensure that dtor pointer passed to app is 0 so it won't be usedRich Felker2011-06-191-0/+1
| | | | | leaving it uninitialized caused unpredictable crashes or worse due to calling an indeterminate function pointer.
* dynamic linker 64bit fix: hash table entries are always 32bitRich Felker2011-06-181-2/+2
|
* experimental dynamic linker!Rich Felker2011-06-185-0/+466
| | | | | | | | 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
* fix memory leak on failure in realpathRich Felker2011-06-181-4/+4
|
* copy-paste error in prctl.hRich Felker2011-06-181-1/+1
|
* fix some struct padding to match LSB/glibc ABI where it may be helpfulRich Felker2011-06-162-2/+5
|
* duplicate re_nsub in LSB/glibc ABI compatible locationRich Felker2011-06-162-2/+3
|
* restore use of .type in asm, but use modern @function (vs %function)Rich Felker2011-06-1420-0/+29
| | | | | | | | 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.
* __syscall5 inline is having trouble with PIC; just use the function for nowRich Felker2011-06-141-0/+7
|
* fix race condition in pthread_killRich Felker2011-06-143-1/+8
| | | | | | | | | | | | | | 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.
* run dtors before taking the exit-lock in pthread exitRich Felker2011-06-141-2/+2
| | | | previously a long-running dtor could cause pthread_detach to block.
* minor locking optimizationsRich Felker2011-06-142-2/+2
|
* avoid 64bit warnings when using pointers as entropy for temp namesRich Felker2011-06-132-2/+4
|
* fix sigset macro for 64-bit systems (<< was overflowing due to wrong type)Rich Felker2011-06-131-1/+1
|
* remove all .size and .type directives for functions from the asmRich Felker2011-06-1318-52/+0
| | | | | these are useless and have caused problems for users trying to build with non-gnu tools like tcc's assembler.
* remove old useless timezone.s file (unused)Rich Felker2011-06-131-27/+0
|
* fix wrong type for wcsrchr argument 2Rich Felker2011-06-131-1/+1
|
* x86_64 fenv support (untested; at least known to build successfully)Rich Felker2011-06-131-0/+88
|
* fix fesetround - it was writing to status word instead of control wordRich Felker2011-06-131-3/+8
|
* floating point environment, untestedRich Felker2011-06-126-0/+144
| | | | | | | | | | 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.
* malloc: cast size down to int in bin_index functionsRich Felker2011-06-121-2/+2
| | | | | | | | | | | 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 Felker2011-06-121-1/+2
|
* add netpacket/packet.hRich Felker2011-06-091-0/+44
| | | | | looks like busybox is going to want it, and apparently some other low-level network software does too...
* it's called getgrgid_r, not getgruid_r...Rich Felker2011-06-081-1/+1
|
* implement psignal and psiginfoRich Felker2011-06-082-0/+20
|
* isgreater etc. relation macros for math.hRich Felker2011-06-081-0/+18
|
* mq names without leading / have impl-def behavior; allowing them is easierRich Felker2011-06-072-9/+2
|
* define MQ_PRIO_MAXRich Felker2011-06-072-1/+2
|
* use __WCHAR_TYPE__ on i386 if it is definedRich Felker2011-06-071-0/+4
| | | | | | | | | | | | | | 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.
* mq send/recv functions are cancellation pointsRich Felker2011-06-072-2/+2
|
* implement mq_notifyRich Felker2011-06-071-2/+65
|
* add support for POSIX message queues, except mq_notifyRich Felker2011-06-0711-0/+133
|
* use __attribute__((const)) for errno and pthread_self if __GNUC__ is definedRich Felker2011-06-062-0/+6
| | | | | this is not too ugly and should result in significant code size and performance improvements for many programs.
