| * | fix errors in sigqueue (potential information leak, wrong behavior) | Rich Felker | 2011-03-10 | 1 | -5/+7 | |
| | | | | | | | | | 1. any padding in the siginfo struct was not necessarily zero-filled, so it might have contained private data off the caller's stack. 2. the uid and pid must be filled in from userspace. the previous rsyscall fix broke rsyscalls because the values were always incorrect. | |||||
| * | security fix: check that cancel/rsyscall signal was sent by the process itself | Rich Felker | 2011-03-10 | 1 | -0/+3 | |
| | | ||||||
| * | more cancellation points: tcdrain, clock_nanosleep | Rich Felker | 2011-03-10 | 2 | -2/+12 | |
| | | ||||||
| * | remove useless return value checks for functions that cannot fail | Rich Felker | 2011-03-10 | 1 | -3/+2 | |
| | | ||||||
| * | make sigsuspend a cancellation point | Rich Felker | 2011-03-10 | 1 | -1/+6 | |
| | | ||||||
| * | make sigtimedwait a cancellation point | Rich Felker | 2011-03-10 | 1 | -0/+3 | |
| | | ||||||
| * | don't fail with EINTR in sigtimedwait | Rich Felker | 2011-03-10 | 1 | -6/+6 | |
| | | | | | | POSIX allows either behavior, but sigwait is not allowed to fail with EINTR, so the retry loop would have to be in one or the other anyway. | |||||
| * | fix sigsuspend syscall | Rich Felker | 2011-03-10 | 1 | -1/+1 | |
| | | ||||||
| * | make sigaltstack work (missing macros in signal.h, error conditions) | Rich Felker | 2011-03-10 | 3 | -1/+15 | |
| | | ||||||
| * | fix errno behavior in clock_* functions | Rich Felker | 2011-03-10 | 3 | -3/+0 | |
| | | | | | | | these functions are specified inconsistent in whether they're specified to return an error value, or return -1 and set errno. hopefully now they all match what POSIX requires. | |||||
| * | fix error handling for pthread_sigmask | Rich Felker | 2011-03-09 | 2 | -1/+15 | |
| | | | | | it must return errno, not -1, and should reject invalud values for how. | |||||
| * | make fork properly initialize the main thread in the child process | Rich Felker | 2011-03-09 | 1 | -0/+7 | |
| | | ||||||
| * | optimize pthread initialization | Rich Felker | 2011-03-09 | 1 | -2/+2 | |
| | | | | | | | the set_tid_address returns the tid (which is also the pid when called from the initial thread) so there is no need to make a separate syscall to get pid/tid. | |||||
| * | fix race condition in raise - just mask signals | Rich Felker | 2011-03-09 | 1 | -9/+9 | |
| | | | | | | | | | a signal handler could fork after the pid/tid were read, causing the wrong process to be signalled. i'm not sure if this is supposed to have UB or not, but raise is async-signal-safe, so it probably is allowed. the current solution is slightly expensive so this implementation is likely to be changed in the future. | |||||
| * | fix raise semantics with threads. | Rich Felker | 2011-03-09 | 1 | -1/+12 | |
| | | ||||||
| * | fix typos in dirent.h | Rich Felker | 2011-03-08 | 1 | -2/+2 | |
| | | ||||||
| * | fcntl.h should make availabel the mode constants from sys/stat.h | Rich Felker | 2011-03-08 | 2 | -8/+20 | |
| | | | | | also remove some legacy nonsense that crept in. | |||||
| * | simplify and optimize pthread_mutex_trylock | Rich Felker | 2011-03-08 | 1 | -17/+16 | |
| | | ||||||
| * | rwlock trylock functions were wrongly returning EAGAIN instead of EBUSY | Rich Felker | 2011-03-08 | 2 | -3/+3 | |
| | | ||||||
| * | fix major breakage in pthread_once (it was always deadlocking) | Rich Felker | 2011-03-08 | 1 | -8/+7 | |
| | | | | | | | the issue was a break statement that was breaking only from the switch, not the enclosing for loop, and a failure to set the final success state. | |||||
| * | fix and optimize non-default-type mutex behavior | Rich Felker | 2011-03-08 | 4 | -25/+19 | |
| | | | | | | | | | | problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time. | |||||
| * | implement pthread_mutexattr_[gs]etpshared functions | Rich Felker | 2011-03-08 | 2 | -0/+16 | |
| | | ||||||
| * | disallow cpu time clocks as condattr clock values | Rich Felker | 2011-03-08 | 1 | -1/+1 | |
| | | ||||||
| * | add macros for use with d_type extension field in dirent | Rich Felker | 2011-03-07 | 1 | -0/+14 | |
| | | ||||||
| * | fix off-by-one error in sem_(timed)wait (using old sem value instead of new) | Rich Felker | 2011-03-07 | 1 | -1/+1 | |
| | | ||||||
| * | use the selected clock from the condattr for pthread_cond_timedwait | Rich Felker | 2011-03-07 | 3 | -1/+3 | |
| | | ||||||
| * | add prototypes for pthread_condattr_* and pthread_rwlockattr_* | Rich Felker | 2011-03-07 | 1 | -0/+12 | |
| | | ||||||
| * | implement pthread_rwlockattr_* (essentially no-ops) | Rich Felker | 2011-03-07 | 4 | -0/+28 | |
| | | ||||||
| * | implement pthread_condattr_* interfaces | Rich Felker | 2011-03-07 | 6 | -0/+45 | |
| | | | | | | note that, while the attributes are stored, they are not used in pthread_cond_init yet. | |||||
| * | reject invalid attribute settings | Rich Felker | 2011-03-07 | 2 | -0/+2 | |
| | | | | | | note that this is a pedantic conformance issue and waste of code. it only affects broken code or code that is probing for conformance. | |||||
| * | implement barrier attribute functions (essentially no-ops) | Rich Felker | 2011-03-07 | 4 | -0/+27 | |
| | | ||||||
| * | enforce stack size min in pthread_attr_setstacksize | Rich Felker | 2011-03-04 | 1 | -1/+1 | |
| | | ||||||
| * | implement POSIX semaphores | Rich Felker | 2011-03-04 | 10 | -0/+201 | |
| | | ||||||
| * | preliminaries to adding POSIX semaphores | Rich Felker | 2011-03-03 | 2 | -1/+8 | |
| | | ||||||
| * | optimize POSIX TSD for fast pthread_getspecific | Rich Felker | 2011-03-03 | 4 | -9/+14 | |
| | | ||||||
| * | namespace cleanup in sys/mman.h | Rich Felker | 2011-03-03 | 1 | -1/+3 | |
| | | ||||||
| * | implement POSIX shared memory | Rich Felker | 2011-03-03 | 2 | -0/+42 | |
| | | ||||||
| * | use -L/...../ -lgcc instead of /...../libgcc.a in musl-gcc wrapper | Rich Felker | 2011-03-01 | 1 | -1/+2 | |
| | | | | | | | this should avoid warnings about unused libs when not linking, and might fix some other obscure issues too. i might replace this approach with a completely different one soon though. | |||||
| * | depends on settimeofday which needs _GNU_SOURCE feature test | Rich Felker | 2011-03-01 | 1 | -0/+1 | |
| | | ||||||
| * | implement futimens and utimensat | Rich Felker | 2011-02-27 | 3 | -0/+16 | |
| | | ||||||
| * | cleanup namespace in sys/time.h | Rich Felker | 2011-02-27 | 1 | -4/+5 | |
| | | ||||||
| * | implement fexecve | Rich Felker | 2011-02-27 | 2 | -0/+11 | |
| | | ||||||
| * | cleanup utf-8 multibyte code, use visibility if possible | Rich Felker | 2011-02-27 | 3 | -84/+5 | |
| | | | | | | | | | | | | | | this code was written independently of musl, with support for a the backwards, nonstandard "31-bit unicode" some libraries/apps might want. unfortunately the extra code (inside #ifdef) makes the source harder to read and makes code that should be simple look complex, so i'm removing it. anyone who wants to use the old code can find it in the history or from elsewhere. also, change the visibility of the __fsmu8 state machine table to hidden, if supported. this should improve performance slightly in shared-library builds. | |||||
| * | fix missing prototype for strsignal | Rich Felker | 2011-02-26 | 2 | -0/+2 | |
| | | ||||||
| * | various changes in preparation for dynamic linking support | Rich Felker | 2011-02-24 | 4 | -8/+24 | |
| | | | | | | | | | | | | | | | | | | prefer using visibility=hidden for __libc internal data, rather than an accessor function, if the compiler has visibility. optimize with -O3 for PIC targets (shared library). without heavy inlining, reloading the GOT register in small functions kills performance. 20-30% size increase for a single libc.so is not a big deal, compared to comparaible size increase in every static binaries. use -Bsymbolic-functions, not -Bsymbolic. global variables are subject to COPY relocations, and thus binding their addresses in the library at link time will cause library functions to read the wrong (original) copies instead of the copies made in the main program's bss section. add entry point, _start, for dynamic linker. | |||||
| * | apply feature test protection to memccpy | Rich Felker | 2011-02-24 | 1 | -1/+4 | |
| | | ||||||
| * | add implementation of memccpy function | Rich Felker | 2011-02-24 | 1 | -0/+32 | |
| | | ||||||
| * | fix backwards conditional in stpncpy | Rich Felker | 2011-02-24 | 1 | -1/+1 | |
| | | | | | | | this only made the function unnecessarily slow on systems with unaligned access, but would of course crash on systems that can't do unaligned accesses (none of which have ports yet). | |||||
| * | rewind must clear the error indicator in addition to seeking | Rich Felker | 2011-02-22 | 1 | -2/+5 | |
| | | ||||||
| * | change errno to static linkage (improves PIC code generation) | Rich Felker | 2011-02-21 | 1 | -4/+2 | |
