*	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	Rich Felker	2011-06-26	1	-3/+3
\| \| \| \|	deps can be null if a library has no dependencies (such as libc itself)
*	fix resolving symbols in objects loaded in RTLD_LOCAL mode	Rich Felker	2011-06-26	1	-0/+11
\| \| \| \| \| \|	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.
*	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	Rich Felker	2011-06-26	1	-2/+19
\| \| \| \| \| \|	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.
*	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	Rich Felker	2011-06-25	3	-4/+6
\| \| \| \| \|	1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt
*	fix dynamic linker issue in musl-gcc wrapper	Rich Felker	2011-06-25	1	-1/+1
\|
*	wordexp cannot use we_offs unless WRDE_DOOFFS flag is set	Rich Felker	2011-06-25	1	-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 Nagy	Rich Felker	2011-06-25	6	-4/+392
\|
*	handle library paths better (ignore empty path components, etc.)	Rich Felker	2011-06-25	1	-3/+5
\|
*	move all limits that don't vary out of bits/limits.h, into main limits.h	Rich Felker	2011-06-25	3	-53/+24
\|
*	fix possible (questionable) strict aliasing violations and ptr arith	Rich Felker	2011-06-25	1	-3/+3
\|
*	const correctness in mq_notify	Rich Felker	2011-06-25	1	-1/+1
\| \| \| \|	why did gcc allow this invalid assignment to compile in the first place?
*	proper path searching for dynamic linker	Rich Felker	2011-06-25	3	-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_CLOEXEC	Rich Felker	2011-06-25	1	-2/+1
\|
*	discard dso descriptors after performing relocations	Rich Felker	2011-06-25	1	-0/+12
\| \| \| \| \|	eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.
*	keep track of which dsos have been relocated	Rich Felker	2011-06-25	1	-0/+1
\|
*	use soname in ld-musl.so to prevent filename appearing in DT_NEEDEDs	Rich Felker	2011-06-24	1	-1/+1
\|
*	use symlink rather than bogus linker script for libc.so	Rich Felker	2011-06-24	1	-2/+2
\| \| \| \|	the linker script caused a bogus DT_NEEDED entry
*	adapt build/install/gcc-wrapper systems for dynamic linking support	Rich Felker	2011-06-23	3	-9/+20
\|
*	prepare support for LD_LIBRARY_PATH (checking suid/sgid safety)	Rich Felker	2011-06-23	1	-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 Nagy	Rich Felker	2011-06-23	3	-12/+111
\|
*	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	Rich Felker	2011-06-19	1	-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 32bit	Rich Felker	2011-06-18	1	-2/+2
\|
*	experimental dynamic linker!	Rich Felker	2011-06-18	5	-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 realpath	Rich Felker	2011-06-18	1	-4/+4
\|
*	copy-paste error in prctl.h	Rich Felker	2011-06-18	1	-1/+1
\|
*	fix some struct padding to match LSB/glibc ABI where it may be helpful	Rich Felker	2011-06-16	2	-2/+5
\|
*	duplicate re_nsub in LSB/glibc ABI compatible location	Rich Felker	2011-06-16	2	-2/+3
\|
*	restore use of .type in asm, but use modern @function (vs %function)	Rich Felker	2011-06-14	20	-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 now	Rich Felker	2011-06-14	1	-0/+7
\|
*	fix race condition in pthread_kill	Rich Felker	2011-06-14	3	-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 exit	Rich Felker	2011-06-14	1	-2/+2
\| \| \| \|	previously a long-running dtor could cause pthread_detach to block.
*	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	Rich Felker	2011-06-13	18	-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 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	Rich Felker	2011-06-12	6	-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.
