2012-08-18make dynamic linker report all failures before exitingRich Felker-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.

2012-08-17crt1 must align stack pointer on mipsRich Felker-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].

2012-08-17fix extremely rare but dangerous race condition in robust mutexesRich Felker-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.
2012-08-17fix float parsing logic for long decimal expansionsRich Felker-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.

2012-08-15improve headers to better deal with removed-in-posix-2008 featuresRich Felker-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.
2012-08-15add missing xattr functionsRich Felker-0/+18
not sure why these were originally omitted..

2012-08-13math: fix _BSD_SOURCE namespace in math.hnsz-25/+26
2012-08-13remove significandlRich Felker-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...
2012-08-13add significand[fl] math functionsRich Felker-0/+25

2012-08-11memcpy asm for i386 and x86_64Rich Felker-0/+51
2012-08-11avoid need for -march=mips2 to compile mips atomic.h asmRich Felker-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.
2012-08-11remove unused but buggy code from strstr.cRich Felker-10/+0
2012-08-11remove buggy short-string wcsstr implementation; always use twowayRich Felker-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.
2012-08-11add bsd fgetln functionRich Felker-1/+25
optimized to avoid allocation and return lines directly out of the stream buffer whenever possible.
2012-08-10minor but worthwhile optimization in printf: avoid expensive strspnRich Felker-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.
2012-08-10trivial optimization to printf: avoid wasted call frameRich Felker-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.
2012-08-10use int instead of long for ptrdiff_t on all 32-bit archsRich Felker-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.
2012-08-10fix incorrect ptrdiff_t type on mipsRich Felker-1/+1
2012-08-10add blowfish hash support to cryptRich Felker-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.
2012-08-09fix (hopefully) all hard-coded 8's for kernel sigset_t sizeRich Felker-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.
2012-08-09add defines for number of sigset_t bytes syscalls expectRich Felker-0/+8
yet another gratuitous mips incompatibility...
2012-08-09make crypt return an unmatchable hash rather than NULL on failureRich Felker-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.

2012-08-05fix socket.h on mipsRich Felker-0/+6
why does mips have to be gratuitously incompatible in every possible imaginable way?
2012-08-05align mips _init/_fini functionsRich Felker-0/+2
since .init and .fini are not .text, the toolchain does not seem to align them for code by default. this yields random breakage depending on the object sizes the linker is dealing with.

2012-08-05mips dynamic linker supportRich Felker-3/+102
not heavily tested, but the basics are working. the basic concept is that the dynamic linker entry point code invokes a pure-PIC (no global accesses) C function in reloc.h to perform the early GOT relocations needed to make the dynamic linker itself functional, then invokes __dynlink like on other archs. since mips uses some ugly arch-specific hacks to optimize relocating the GOT (rather than just using the normal DT_REL[A] tables like on other archs), the dynamic linker has been modified slightly to support calling arch-specific relocation code in reloc.h. most of the actual mips-specific behavior was developed by reading the output of readelf on libc.so and simple executable files. i could not find good reference information on which relocation types need to be supported or their semantics, so it's possible that some legitimate usage cases will not work yet.
