Rich Felker	b768c7bc63	make gcc wrapper support -shared correctly it was previously attempting to link start files as part of shared objects. this is definitely wrong and depending on the platform and linker could range from just adding extraneous junk to introducing textrels to making linking fail entirely.	15 years ago
Rich Felker	d0678b58ab	make glob mark symlinks-to-directories with the GLOB_MARK flag POSIX is unclear on whether it should, but all historical implementations seem to behave this way, and it seems more useful to applications.	15 years ago
Rich Felker	fd7015d0c2	fix broken copy relocations from dynamic linker cleanup this issue affected programs which use global variables exported by non-libc libraries.	15 years ago
Rich Felker	e12fe65c92	dynamic linker support for PIE binaries (position-independent main program) even with this change, PIE will not work yet due to deficiencies in the crt1.o startup code.	15 years ago
Rich Felker	c82f4a32ec	cleanup dynamic linker, removing some code duplication	15 years ago
Rich Felker	35620515a8	update release notes for 0.8.4	15 years ago
Rich Felker	ce7d72596c	fix cancellation failure in single-threaded programs even a single-threaded program can be cancellable, e.g. if it's called pthread_cancel(pthread_self()). the correct predicate to check is not whether multiple threads have been invoked, but whether pthread_self has been invoked.	15 years ago
Rich Felker	787c2648a9	support GLOB_PERIOD flag (GNU extension) to glob function patch by sh4rm4	15 years ago
Rich Felker	4904b64275	update WHATSNEW in preparation for 0.8.4 (not finished)	15 years ago
Rich Felker	5235a2a5a4	use prlimit syscall for getrlimit/setrlimit this allows the full range of 64-bit limit arguments even on 32-bit systems. fallback to the old syscalls on old kernels that don't support prlimit.	15 years ago
Rich Felker	26f38328d6	add prlimit syscall wrapper	15 years ago
Rich Felker	0b6dc09744	fix dynamic linker not to depend on DYNAMIC ptr in 0th entry of GOT this fixes an issue using gold instead of gnu ld for linking. it also should eliminate the need of the startup code to even load/pass the got address to the dynamic linker. based on patch submitted by sh4rm4 with minor cosmetic changes. further cleanup will follow.	15 years ago
Rich Felker	07065210ca	alias basename to glibc name for it, to meet abi goals note that regardless of the name used, basename is always conformant. it never takes on the bogus gnu behavior, unlike glibc where basename is nonconformant when declared manually without including libgen.h.	15 years ago
Rich Felker	2adf2fb372	fix char signedness bug in dynlinker hash function this only affects non-ascii symbol names, which are probably not in use anyway..	15 years ago
Rich Felker	c07daf0f2f	fix broken reboot wrapper (syscall needs extra silly magic arguments...)	15 years ago
Rich Felker	e5d78fe8df	fix issue with excessive mremap syscalls on realloc CHUNK_SIZE macro was defined incorrectly and shaving off at least one significant bit in the size of mmapped chunks, resulting in the test for oldlen==newlen always failing and incurring a syscall. fortunately i don't think this issue caused any other observable behavior; the definition worked correctly for all non-mmapped chunks where its correctness matters more, since their lengths are always multiples of the alignment.	15 years ago
Rich Felker	4e3df7be8f	fix __cplusplus extern "C" closing brace in pty.h (typo?)	15 years ago
Rich Felker	0c4188f6d7	fix signed overflows at most-negative values in ato(i\|l\|ll) patch by Pascal Cuoq (with minor tweaks to comments)	15 years ago
Rich Felker	3ed8c9f2df	fix all missing instances of __cplusplus checks/extern "C" in headers patch by Arvid Picciani (aep)	15 years ago
Rich Felker	26120950e2	report sem value overflows in sem_post this is not required by the standard, but it's nicer than corrupting the state and rather inexpensive.	15 years ago
Rich Felker	42976cee2d	add some missing GNU FNM_* extensions to the header note that none of these are implemented, and programs depending on them may break... patch by sh4rm4	15 years ago
Rich Felker	03860303c2	fix some details in ugly stuff that doesn't belong in libc patches by sh4rm4, presumably needed to make gdb or some similar junk happy...	15 years ago
Rich Felker	1d3c276807	don't define wchar_t on c++ it's a keyword in c++ (wtf). i'm not sure this is the cleanest solution; it might be better to avoid ever defining __NEED_wchar_t on c++. but in any case, this works for now.	15 years ago
Rich Felker	2bb75db611	support vfork on i386	15 years ago
Rich Felker	768f39a535	make available a namespace-safe vfork, if supported this may be useful to posix_spawn..?	15 years ago
Rich Felker	14f2e115c2	add dummy __cxa_finalize musl's dynamic linker does not support unloading dsos, so there's nothing for this function to do. adding the symbol in case anything depends on its presence..	15 years ago
Rich Felker	b7c683be35	support __cxa_atexit, and registering atexit functions from atexit handlers mildly tested; may have bugs. the locking should be updated not to use spinlocks but that's outside the scope of this one module.	15 years ago
Rich Felker	f753049a50	simplify atexit and fflush-on-exit handling	15 years ago
Rich Felker	8e8ddeff7e	fix F_GETOWN return value handling the fcntl syscall can return a negative value when the command is F_GETOWN, and this is not an error code but an actual value. thus we must special-case it and avoid calling __syscall_ret to set errno. this fix is better than the glibc fix (using F_GETOWN_EX) which only works on newer kernels and is more complex.	15 years ago
Rich Felker	2b89e56c94	fix typo in arm clone() asm	15 years ago
Rich Felker	e6d765a8b1	fix fcntl O_* flags for arm no idea why these 4 are permuted and the rest are standard/generic	15 years ago
Rich Felker	73f5ff4e86	make [U]INTn_C() macros have the right type... ...and still be valid in #if directives.	15 years ago
Rich Felker	5e977e8b48	recovering ownerdead robust mutex must reset recursive lock count	15 years ago
Rich Felker	b6f9974ad8	simplify robust mutex unlock code path right now it's questionable whether this change is an improvement or not, but if we later want to support priority inheritance mutexes, it will be important to have the code paths unified like this to avoid major code duplication.	15 years ago
Rich Felker	b8688ff875	fix crash if pthread_mutex_unlock is called without ever locking this is valid for error-checking mutexes; otherwise it invokes UB and would be justified in crashing.	15 years ago
Rich Felker	7fe58d3511	use count=0 instead of 1 for recursive mutex with only one lock reference this simplifies the code paths slightly, but perhaps what's nicer is that it makes recursive mutexes fully reentrant, i.e. locking and unlocking from a signal handler works even if the interrupted code was in the middle of locking or unlocking.	15 years ago
Rich Felker	b3b00d11e8	sysconf for PTHREAD_KEYS_MAX	15 years ago
Rich Felker	5a2e180937	synchronize cond var destruction with exiting waits	15 years ago
Rich Felker	b85fec2ded	fix failure-to-wake in rwlock unlock a reader unlocking the lock need only wake one waiter (necessarily a writer, but a writer unlocking the lock must wake all waiters (necessarily readers). if it only wakes one, the remainder can remain blocked indefinitely, or at least until the first reader unlocks (in which case the whole lock becomes serialized and behaves as a mutex rather than a read lock).	15 years ago
Rich Felker	8b98c09f8c	dlsym entry point for arm	15 years ago
Rich Felker	fcaf706569	dynamic linker entry point for arm mildly tested, seems to work	15 years ago
Rich Felker	74cc7c69f9	typo (copy 2) in arm reloc.h	15 years ago
Rich Felker	cd319d73c7	typo in arm reloc.h	15 years ago
Rich Felker	12ace5bf76	first attempt at arm dynamic linking	15 years ago
Rich Felker	4b87736998	fix various bugs in path and error handling in execvp/fexecve	15 years ago
Rich Felker	5f814682b4	don't crash on null strings in printf passing null pointer for %s is UB but lots of broken programs do it anyway	15 years ago
Rich Felker	de543b05c8	fix excessive/insufficient wakes in __vm_unlock there is no need to send a wake when the lock count does not hit zero, but when it does, all waiters must be woken (since all with the same sign are eligible to obtain the lock).	15 years ago
Rich Felker	ede5ae7b0b	make getmntent_r discard long lines when it returns error, not seek back seeking back can be performed by the caller, but if the caller doesn't expect it, it will result in an infinite loop of failures.	15 years ago
Rich Felker	9cee9307e3	improve pshared barriers eliminate the sequence number field and instead use the counter as the futex because of the way the lock is held, sequence numbers are completely useless, and this frees up a field in the barrier structure to be used as a waiter count for the count futex, which lets us avoid some syscalls in the best case. as of now, self-synchronized destruction and unmapping should be fully safe. before any thread can return from the barrier, all threads in the barrier have obtained the vm lock, and each holds a shared lock on the barrier. the barrier memory is not inspected after the shared lock count reaches 0, nor after the vm lock is released.	15 years ago
Rich Felker	95b1479672	next step making barrier self-sync'd destruction safe i think this works, but it can be simplified. (next step)	15 years ago
