Rich Felker	e411827960	use type directives for fenv asm functions	15 years ago
Rich Felker	bf30100ad7	use load address from elf header if possible this is mostly useless for shared libs (though it could help for prelink-like purposes); the intended use case is for adding support for calling the dynamic linker directly to run a program, as in: ./libc.so ./a.out foo this usage is not yet supported.	15 years ago
Rich Felker	c7debe13ee	make dynamic linker relocate the main program image last, after all libs prior to this change, copy relocations for initialized pointer variables would not reflect the relocated contents of the pointer.	15 years ago
Rich Felker	9e17b71fa6	fix stale pointer issue in dynamic linker with dlopen	15 years ago
Rich Felker	06933cc724	don't leave the lock held on dlopen failure..	15 years ago
Rich Felker	97507bde47	add RTLD_DEFAULT support	15 years ago
Rich Felker	0e4dae3d77	in dlopen: don't use null pointer deps can be null if a library has no dependencies (such as libc itself)	15 years ago
Rich Felker	92ab5d8d15	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.	15 years ago
Rich Felker	59ab43f5f8	experimental dlopen/dlsym and dynlink changes needed to support them	15 years ago
Rich Felker	bc30aea457	type directives for x86_64 math asm	15 years ago
Rich Felker	6b3d5e508f	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.	15 years ago
Rich Felker	6e53a6eca4	fix useless use of potentially-uninitialized mode variable in sem_open	15 years ago
Rich Felker	5d0965cb56	eliminate OOB array hacks in malloc	15 years ago
Rich Felker	e22c2d3ee6	use .type directives for math asm (needed for dynamic linking to work)	15 years ago
Rich Felker	32de61e81a	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	15 years ago
Rich Felker	6250c0be4b	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.	15 years ago
Rich Felker	febbd12d00	XSI search.h API implementation by Szabolcs Nagy	15 years ago
Rich Felker	49388f3b7b	handle library paths better (ignore empty path components, etc.)	15 years ago
Rich Felker	59633c736d	fix possible (questionable) strict aliasing violations and ptr arith	15 years ago
Rich Felker	4d95a58524	const correctness in mq_notify why did gcc allow this invalid assignment to compile in the first place?	15 years ago
Rich Felker	568b8075a4	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.	15 years ago
Rich Felker	f937031800	optimize opendir using O_CLOEXEC	15 years ago
Rich Felker	e8dbf00a78	discard dso descriptors after performing relocations eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.	15 years ago
Rich Felker	368ba4a0a9	keep track of which dsos have been relocated	15 years ago
Rich Felker	b7f6e0c6f8	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.	15 years ago
Rich Felker	c7ce1b20d2	initial commit of prng implementation by Szabolcs Nagy	15 years ago
Rich Felker	d19adeec52	make ldso asm more uniform with rest of codebase (no unnecessary suffixes)	15 years ago
Rich Felker	779165e6d4	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.	15 years ago
Rich Felker	596d60c565	dynamic linker 64bit fix: hash table entries are always 32bit	15 years ago
Rich Felker	51e2d83102	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	15 years ago
Rich Felker	d43ff110bc	fix memory leak on failure in realpath	15 years ago
Rich Felker	32aea2087a	duplicate re_nsub in LSB/glibc ABI compatible location	15 years ago
Rich Felker	c7d19f9923	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.	15 years ago
Rich Felker	7779dbd266	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.	15 years ago
Rich Felker	f58c8a0f39	run dtors before taking the exit-lock in pthread exit previously a long-running dtor could cause pthread_detach to block.	15 years ago
Rich Felker	6232b96f51	minor locking optimizations	15 years ago
Rich Felker	0e1762539c	avoid 64bit warnings when using pointers as entropy for temp names	15 years ago
Rich Felker	f09e78de98	fix sigset macro for 64-bit systems (<< was overflowing due to wrong type)	15 years ago
Rich Felker	1e4f1cf154	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.	15 years ago
Rich Felker	76100a724e	remove old useless timezone.s file (unused)	15 years ago
Rich Felker	73d2fde119	fix wrong type for wcsrchr argument 2	15 years ago
Rich Felker	773b0fe447	x86_64 fenv support (untested; at least known to build successfully)	15 years ago
Rich Felker	52cf24a0f4	fix fesetround - it was writing to status word instead of control word	15 years ago
Rich Felker	b09b78905b	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.	15 years ago
Rich Felker	2afebbbcd1	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.	15 years ago
Rich Felker	3825847243	another return value fix for mktemp...	15 years ago
Rich Felker	c19a6be5a1	it's called getgrgid_r, not getgruid_r...	15 years ago
