* implement "low hanging fruit" from C11Rich Felker2012-08-257-49/+75
| | | | | | | | based on Gregor's patch sent to the list. includes: - stdalign.h - removing gets in C11 mode - adding aligned_alloc and adjusting other functions to use it - adding 'x' flag to fopen for exclusive mode
* add c11 quick_exit and at_quick_exit functionsRich Felker2012-08-253-0/+46

* fix bug in gnu hash lookup on dlsym(handle, name) lookupsRich Felker2012-08-251-1/+1
| | | | | | wrong hash was being passed; just a copy/paste error. did not affect lookups in the global namespace; this is probably why it was not caught in testing.
* clean up search_vec usage for vdsoRich Felker2012-08-251-2/+2
|
* use new search_vec function to find vdso in dynamic linkerRich Felker2012-08-251-4/+2
|
* ensure canary is setup if stack-prot libs are dlopen'd into non-ssp appRich Felker2012-08-252-2/+6
| | | | | | previously, this usage could lead to a crash if the thread pointer was still uninitialized, and otherwise would just cause the canary to be zero (less secure).
* add gnu hash support in the dynamic linkerRich Felker2012-08-252-13/+86
| | | | based on the patches contributed by boris brezillon.

* make dynamic linker report all failures before exitingRich Felker2012-08-181-2/+6
| | | | | | | | | before, only the first library that failed to load or symbol that failed to resolve was reported, and then the dynamic linker immediately exited. when attempting to fix a library compatibility issue, this is about the worst possible behavior. now we print all errors as they occur and exit at the very end if errors were encountered.

* crt1 must align stack pointer on mipsRich Felker2012-08-171-0/+1
| | | | | | it's naturally aligned when entered with the kernel argv array, but if ld.so has been invoked explicitly to run a program, the stack will not be aligned due to having thrown away argv[0].
* fix bug computing argc when invoking ld-musl-mips.so.1 progname ...Rich Felker2012-08-171-3/+3

* split up installation targetRich Felker2012-08-171-2/+10
| | | | patch by Luca Barbato (lu_zero)
* fix extremely rare but dangerous race condition in robust mutexesRich Felker2012-08-173-20/+33
| | | | | | | | | | if new shared mappings of files/devices/shared memory can be made between the time a robust mutex is unlocked and its subsequent removal from the pending slot in the robustlist header, the kernel can inadvertently corrupt data in the newly-mapped pages when the process terminates. i am fixing the bug by using the same global vm lock mechanism that was used to fix the race condition with unmapping barriers after pthread_barrier_wait returns.
* fix float parsing logic for long decimal expansionsRich Felker2012-08-171-1/+1
| | | | | | | | | | | | | | | | this affects at least the case of very long inputs, but may also affect shorter inputs that become long due to growth while upscaling. basically, the logic for the circular buffer indices of the initial base-10^9 digit and the slot one past the final digit, and for simplicity of the loop logic, assumes an invariant that they're not equal. the upscale loop, which can increase the length of the base-10^9 representation, attempted to preserve this invariant, but was actually only ensuring that the end index did not loop around past the start index, not that the two never become equal. the main (only?) effect of this bug was that subsequent logic treats the excessively long number as having no digits, leading to junk results.
* handle null arguments to legacy bsd err.h functionsRich Felker2012-08-151-2/+2

* improve headers to better deal with removed-in-posix-2008 featuresRich Felker2012-08-152-13/+22
| | | | | | | | | with this patch, setting _POSIX_SOURCE, or setting _POSIX_C_SOURCE or _XOPEN_SOURCE to an old version, will bring back the interfaces that were removed in POSIX 2008 - at least the ones i've covered so far, which are gethostby*, usleep, and ualarm. if there are other functions still in widespread use that were removed for which similar changes would be beneficial, they can be added just like this.
* add missing xattr functionsRich Felker2012-08-152-0/+18

* | remove significandlRich Felker2012-08-132-8/+0
| | | | | | | | | | | | | | this function never existed historically; since the float/double functions it's based on are nonstandard and deprecated, there's really no justification for its existence except that glibc has it. it can be added back if there's ever really a need...

* | avoid need for -march=mips2 to compile mips atomic.h asmRich Felker2012-08-111-0/+8
| | | | | | | | | | | | linux guarantees ll/sc are always available. on mips1, they will be emulated by the kernel. thus they are part of the linux mips1 abi and safe to use.

| |
* | remove buggy short-string wcsstr implementation; always use twowayRich Felker2012-08-111-9/+0
| | | | | | | | | | | | since this interface is rarely used, it's probably best to lean towards keeping code size down anyway. one-character needles will still be found immediately by the initial wcschr call anyway.
* | add bsd fgetln functionRich Felker2012-08-114-1/+25
| | | | | | | | | | optimized to avoid allocation and return lines directly out of the stream buffer whenever possible.
* | minor but worthwhile optimization in printf: avoid expensive strspnRich Felker2012-08-101-4/+2
| | | | | | | | | | | | the strspn call was made for every format specifier and end-of-string, even though the expected return value was 1-2 for normal usage. replace with simple loop.
* | trivial optimization to printf: avoid wasted call frameRich Felker2012-08-101-1/+1
| | | | | | | | | | | | | | | | amusingly, this cuts more than 10% off the run time of printf("a"); on the machine i tested it on. sadly the same optimization is not possible for snprintf without duplicating all the pseudo-FILE setup code, which is not worth it.
* | use int instead of long for ptrdiff_t on all 32-bit archsRich Felker2012-08-102-2/+2
| | | | | | | | | | | | | | | | this is needed to match the underlying "ABI" standards. it's not really an ABI issue since the binary representations are the same, but having the wrong type can lead to errors when the type arising from a difference-of-pointers expression does not match the defined type of ptrdiff_t. most of the problems affect C++, not C.

* | add blowfish hash support to cryptRich Felker2012-08-103-8/+806
| | | | | | | | | | | | | | there are still some discussions going on about tweaking the code, but at least thing brings us to the point of having something working in the repository. hopefully the remaining major hashes (md5,sha) will follow soon.
* | fix (hopefully) all hard-coded 8's for kernel sigset_t sizeRich Felker2012-08-0914-20/+31
| | | | | | | | | | | | | | | | | | | | some minor changes to how hard-coded sets for thread-related purposes are handled were also needed, since the old object sizes were not necessarily sufficient. things have gotten a bit ugly in this area, and i think a cleanup is in order at some point, but for now the goal is just to get the code working on all supported archs including mips, which was badly broken by linux rejecting syscalls with the wrong sigset_t size.
* | add defines for number of sigset_t bytes syscalls expectRich Felker2012-08-094-0/+8
| | | | | | | | yet another gratuitous mips incompatibility...
* | make crypt return an unmatchable hash rather than NULL on failureRich Felker2012-08-091-5/+2
|/ | | | | | | | | | | | | | | | unfortunately, a large portion of programs which call crypt are not prepared for its failure and do not check that the return value is non-null before using it. thus, always "succeeding" but giving an unmatchable hash is reportedly a better behavior than failing on error. it was suggested that we could do this the same way as other implementations and put the null-to-unmatchable translation in the wrapper rather than the individual crypt modules like crypt_des, but when i tried to do it, i found it was making the logic in __crypt_r for keeping track of which hash type we're working with and whether it succeeded or failed much more complex, and potentially error-prone. the way i'm doing it now seems to have essentially zero cost, anyway.
