| * | fix simple_malloc size restrictions | Rich Felker | 2011-02-20 | 1 | -5/+6 | |
| | | | | | | | do not allow allocations that overflow ptrdiff_t; fix some overflow checks that were not quite right but didn't matter due to address layout implementation. | |||||
| * | fix null pointer dereference introduced in last sigprocmask commit | Rich Felker | 2011-02-20 | 1 | -1/+1 | |
| | | ||||||
| * | make real symbols for the legacy (nonstandardized) utmp functions | Rich Felker | 2011-02-20 | 2 | -6/+23 | |
| | | | | | | | | this is needed in the long term for ABI compatibility anyway, and in the immediate, it helps with building broken programs like GNU screen that try to prototype the functions themselves rather than using the header. | |||||
| * | resolve some header namespace non-issues | Rich Felker | 2011-02-20 | 2 | -3/+0 | |
| | | | | | | after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection. | |||||
| * | move the GNU siginfo renaming so it doesn't lead to mismatching names | Rich Felker | 2011-02-20 | 1 | -1/+4 | |
| | | ||||||
| * | fill in some missing siginfo stuff in signal.h | Rich Felker | 2011-02-20 | 2 | -10/+112 | |
| | | ||||||
| * | make sys/param.h not depend on PATH_MAX and NAME_MAX | Rich Felker | 2011-02-20 | 1 | -2/+2 | |
| | | | | | | | | | | | | this is a nonstandard header used only by backwards programs, but for some reason it's extremely popular. the recent namespace cleanup fixes broke it, because PATH_MAX and NAME_MAX will not be defined unless an approriate feature test macro has been defined. moreover, it's too late to just #define _GNU_SOURCE in param.h, since limits.h may have already been included. let's just hard-code standard values and be done with it. | |||||
| * | workaround gcc bug 46926 by providing a dumb sincos implementation | Rich Felker | 2011-02-19 | 1 | -0/+8 | |
| | | | | | | | note that this library itself is built with -ffreestanding so sincos.c should not be miscompiled even if the gcc used to compile musl has this bug. | |||||
| * | use rt_sigprocmask, not legacy sigprocmask, syscall in pthread exit code | Rich Felker | 2011-02-19 | 1 | -1/+1 | |
| | | ||||||
| * | fix typo in wordexp.h (note that the function is still unimplemented) | Rich Felker | 2011-02-19 | 1 | -1/+1 | |
| | | ||||||
| * | implement the remaining clock_* interfaces | Rich Felker | 2011-02-19 | 5 | -0/+36 | |
| | | ||||||
| * | race condition fix: block all signals before decrementing thread count | Rich Felker | 2011-02-19 | 3 | -22/+2 | |
| | | | | | | | | | | | | | the existence of a (kernelspace) thread must never have observable effects after the thread count is decremented. if signals are not blocked, it could end up handling the signal for rsyscall and contributing towards the count of threads which have changed ids, causing a thread to be missed. this could lead to one thread retaining unwanted privilege level. this change may also address other subtle race conditions in application code that uses signals. | |||||
| * | prevent sigprocmask/pthread_sigmask from blocking implementation signals | Rich Felker | 2011-02-19 | 1 | -3/+5 | |
| | | | | | | | this code was wrongly disabled because the old version was trying to be too clever and didn't work. replaced it with a simple version for now. | |||||
| * | make pthread_exit run dtors for last thread, wait to decrement thread count | Rich Felker | 2011-02-19 | 1 | -3/+3 | |
| | | ||||||
| * | make mktemp match the historic behavior, and update functions that use it | Rich Felker | 2011-02-19 | 3 | -5/+8 | |
| | | | | | | | the historic mktemp is supposed to blank the template string on failure, rather than returning 0. just zero the first character so that mkstemp and mkdtemp can still retry with O(1) space requirement. | |||||
| * | fix major bug created from copying mkdtemp logic | Rich Felker | 2011-02-19 | 1 | -1/+1 | |
| | | ||||||
| * | add syscall wrappers for inotify | Rich Felker | 2011-02-19 | 5 | -0/+83 | |
| | | ||||||
| * | cleanup cruft left from when kernel and user time_t disagreed | Rich Felker | 2011-02-19 | 2 | -12/+3 | |
| | | ||||||
| * | prototype wait3 and wait4 | Rich Felker | 2011-02-19 | 2 | -3/+6 | |
| | | ||||||
| * | add missing WIFCONTINUED macro and improve WIFSIGNALED | Rich Felker | 2011-02-19 | 2 | -2/+4 | |
| | | ||||||
| * | prototypes for brk and sbrk | Rich Felker | 2011-02-19 | 1 | -0/+2 | |
| | | ||||||
| * | support the ugly and deprecated ucontext and sigcontext header stuff... | Rich Felker | 2011-02-18 | 3 | -20/+69 | |
| | | | | | | | | | | | | | | | only the structures, not the functions from ucontext.h, are supported at this point. the main goal of this commit is to make modern gcc with dwarf2 unwinding build without errors. honestly, it probably doesn't matter how we define these as long as they have members with the right names to prevent errors while compiling libgcc. the only time they will be used is for propagating exceptions across signal-handler boundaries, which invokes undefined behavior anyway. but as-is, they're probably correct and may be useful to various low-level applications dealing with virtualization, jit code generation, and so on... | |||||
| * | add pthread_atfork interface | Rich Felker | 2011-02-18 | 4 | -3/+57 | |
| | | | | | | | | | | note that this presently does not handle consistency of the libc's own global state during forking. as per POSIX 2008, if the parent process was threaded, the child process may only call async-signal-safe functions until one of the exec-family functions is called, so the current behavior is believed to be conformant even if non-ideal. it may be improved at some later time. | |||||
| * | major improvements to temp file name generator | Rich Felker | 2011-02-18 | 3 | -16/+21 | |
| | | | | | | | | | use current time in nanoseconds and some potentially-random (if aslr is enabled) pointer values for the initial tempfile name generation, and step via a cheap linear prng on collisions. limit the number of retry attempts to prevent denial of service attacks even if an attacker can guess the filenames. | |||||
| * | reformat mkstemp like mkdtemp | Rich Felker | 2011-02-18 | 1 | -7/+5 | |
| | | | | | | this is cleaner and makes it easy to impose a limit on the number of retries later if it seems desirable to do so. | |||||
| * | add portable lchown (trivial to support and a few ancient things want it..) | Rich Felker | 2011-02-17 | 2 | -0/+10 | |
| | | ||||||
| * | prepare WHATSNEW for release v0.6.0 | Rich Felker | 2011-02-17 | 1 | -1/+1 | |
| | | ||||||
| * | document in config.mak sample that x86_64 is supported | Rich Felker | 2011-02-17 | 1 | -1/+1 | |
| | | ||||||
| * | update WHATSNEW in preparation for release | Rich Felker | 2011-02-17 | 1 | -2/+9 | |
| | | ||||||
| * | avoid deleting the lib/empty file | Rich Felker | 2011-02-17 | 1 | -1/+1 | |
| | | ||||||
| * | reorganize pthread data structures and move the definitions to alltypes.h | Rich Felker | 2011-02-17 | 28 | -128/+158 | |
| | | | | | | | | | this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test. | |||||
| * | new solution for empty lib dir (old one had some problems) | Rich Felker | 2011-02-17 | 2 | -7/+5 | |
| | | ||||||
| * | improve Makefile handling of git checkouts with missing lib/ and config.mak | Rich Felker | 2011-02-17 | 1 | -4/+8 | |
| | | ||||||
| * | make daemon try the operations that might fail before fork rather than after | Rich Felker | 2011-02-17 | 1 | -12/+10 | |
| | | ||||||
| * | daemon should check for failures and return -1 | Rich Felker | 2011-02-17 | 1 | -5/+8 | |
| | | ||||||
| * | don't compare elements with themselves during qsort. | Rich Felker | 2011-02-17 | 1 | -1/+1 | |
| | | | | | | this is actually a workaround for a bug in gcc, whereby it asserts inequality of the keys being compared... | |||||
| * | ucontext is no longer in the standard, so use gnu-friendly struct name | Rich Felker | 2011-02-16 | 1 | -2/+2 | |
| | | | | | | note that this header is still bogus and needs a lot of work and factoring into arch-dependent parts... | |||||
| * | some gnu software wrongly uses "struct siginfo" instead of siginfo_t... | Rich Felker | 2011-02-16 | 1 | -0/+1 | |
| | | ||||||
| * | add to pthread.h: pthread_mutex_timedlock and sched.h, time.h | Rich Felker | 2011-02-16 | 1 | -1/+3 | |
| | | ||||||
| * | fix printf %n specifier - missing breaks had it clobbering memory | Rich Felker | 2011-02-16 | 1 | -7/+7 | |
| | | ||||||
| * | patch by njk, simplifies thread register initialization for x86_64 | Rich Felker | 2011-02-16 | 1 | -4/+0 | |
| | | | | | | It's not necessary to save any registers on the stack across syscall in x86_64 __set_thread_area. Don't waste cycles or bytes on it. | |||||
| * | patch from njk: make x86_64 __uniclone branchless. | Rich Felker | 2011-02-16 | 1 | -6/+6 | |
| | | ||||||
| * | fix compile failure: legacy cuserid needs to define feature test | Rich Felker | 2011-02-16 | 1 | -0/+1 | |
| | | ||||||
| * | move stdio stuff that's not arch-specific out of bits | Rich Felker | 2011-02-15 | 3 | -28/+9 | |
| | | ||||||
| * | protect some limit constants with feature test macros on x86_64 | Rich Felker | 2011-02-15 | 1 | -1/+3 | |
| | | ||||||
| * | fix the types of some integer constant limits in headers | Rich Felker | 2011-02-15 | 3 | -5/+5 | |
| | | ||||||
| * | fix missing EXIT_* in stdlib.h after header cleanup | Rich Felker | 2011-02-15 | 1 | -3/+3 | |
| | | ||||||
| * | feature test support in unistd.h | Rich Felker | 2011-02-15 | 1 | -23/+27 | |
| | | ||||||
| * | fix directory reading on x86_64 | Rich Felker | 2011-02-15 | 1 | -0/+2 | |
