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	e0b0ff1598	use soname in ld-musl.so to prevent filename appearing in DT_NEEDEDs	15 years ago
Rich Felker	a654b0243b	use symlink rather than bogus linker script for libc.so the linker script caused a bogus DT_NEEDED entry	15 years ago
Rich Felker	ec05a0b08f	adapt build/install/gcc-wrapper systems for dynamic linking support	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	5a2e74ebd2	copy-paste error in prctl.h	15 years ago
Rich Felker	7f5471529c	fix some struct padding to match LSB/glibc ABI where it may be helpful	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	836ba93d93	__syscall5 inline is having trouble with PIC; just use the function for now	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	2697b4e755	add netpacket/packet.h looks like busybox is going to want it, and apparently some other low-level network software does too...	15 years ago

Rich Felker	ecc0f5138d	implement psignal and psiginfo	15 years ago

Rich Felker	e1d2a8e239	mq names without leading / have impl-def behavior; allowing them is easier	15 years ago
Rich Felker	2b0cedac8d	define MQ_PRIO_MAX	15 years ago
Rich Felker	0b6b43ed3f	use __WCHAR_TYPE__ on i386 if it is defined 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.	15 years ago
Rich Felker	86f8c72bb1	mq send/recv functions are cancellation points	15 years ago
Rich Felker	ede353d8e5	implement mq_notify	15 years ago
Rich Felker	ab11386aaa	add support for POSIX message queues, except mq_notify	15 years ago
Rich Felker	cbf35978a9	use __attribute__((const)) for errno and pthread_self if __GNUC__ is defined this is not too ugly and should result in significant code size and performance improvements for many programs.	15 years ago
Rich Felker	71a80c5767	use volatile pointers for intentional-crash code.	15 years ago
Rich Felker	da88b16a22	fix handling of d_name in struct dirent basically there are 3 choices for how to implement this variable-size string member: 1. C99 flexible array member: breaks using dirent.h with pre-C99 compiler. 2. old way: length-1 string: generates array bounds warnings in caller. 3. new way: length-NAME_MAX string. no problems, simplifies all code. of course the usable part in the pointer returned by readdir might be shorter than NAME_MAX+1 bytes, but that is allowed by the standard and doesn't hurt anything.	15 years ago
Rich Felker	0dc99ac413	safety fix for glob's vla usage: disallow patterns longer than PATH_MAX this actually inadvertently disallows some valid patterns with redundant / or * characters, but it's better than allowing unbounded vla allocation. eventually i'll write code to move the pattern to the stack and eliminate redundancy to ensure that it fits in PATH_MAX at the beginning of glob. this would also allow it to be modified in place for passing to fnmatch rather than copied at each level of recursion.	15 years ago
Rich Felker	a6c399cf62	eliminate (harmless in this case) vla usage in fnmatch.c	15 years ago
Rich Felker	c74d306f47	missing prototypes for mbsnrtowcs and wcsnrtombs	15 years ago
