* fix breakage due to converting a return type to size_t in iconv...Rich Felker2011-04-071-1/+1
|
* fixed crash in new rsyscall (failure to set sa_flags for signal handler)Rich Felker2011-04-061-0/+2
|
* consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefixRich Felker2011-04-0638-40/+40
|
* move rsyscall out of pthread_create moduleRich Felker2011-04-0610-109/+133
| | | | | | | | | | | | | | this is something of a tradeoff, as now set*id() functions, rather than pthread_create, are what pull in the code overhead for dealing with linux's refusal to implement proper POSIX thread-vs-process semantics. my motivations are: 1. it's cleaner this way, especially cleaner to optimize out the rsyscall locking overhead from pthread_create when it's not needed. 2. it's expected that only a tiny number of core system programs will ever use set*id() functions, whereas many programs may want to use threads, and making thread overhead tiny is an incentive for "light" programs to try threads.
* pthread exit stuff: don't bother setting errno when we won't check it.Rich Felker2011-04-061-2/+2
|
* fix rsyscall handler: must not clobber errno from signal contextRich Felker2011-04-061-2/+4
|
* fix typo in sys/msg.hRich Felker2011-04-061-1/+1
|
* add startup abi functions, dummy for now. eventually needed for c++ support.Rich Felker2011-04-062-0/+10
|
* add _res (__res_state()) dummyRich Felker2011-04-061-0/+9
|
* add IN_LOOPBACKNET constant (nonstandard but in reserved namespace)Rich Felker2011-04-061-0/+2
|
* document more changes for 0.7.7 v0.7.7Rich Felker2011-04-061-1/+10
|
* fix prototype for strsepRich Felker2011-04-062-1/+2
|
* fix completely bogus loop condition in getmntent_rRich Felker2011-04-061-1/+1
| | | | | somehow this worked on my simple fstab, but horribly broke in general, leading to use of uninitialized offset array and crashes.
* major semaphore improvements (performance and correctness)Rich Felker2011-04-065-21/+37
| | | | | 1. make sem_[timed]wait interruptible by signals, per POSIX 2. keep a waiter count in order to avoid unnecessary futex wake syscalls
* fix signal-based timers with null sigevent argumentRich Felker2011-04-065-28/+19
| | | | | | | | | | | | | since timer_create is no longer allocating a structure for the timer_t and simply using the kernel timer id, it was impossible to specify the timer_t as the argument to the signal handler. the solution is to pass the null sigevent pointer on to the kernel, rather than filling it in userspace, so that the kernel does the right thing. however, that precludes the clever timerid-versus-threadid encoding we were doing. instead, just assume timerids are below 1M and thread pointers are above 1M. (in perspective: timerids are sequentially allocated and seem limited to 32k, and thread pointers are at roughly 3G.)
* fix incorrect (and conflicting on LP64 archs) types for sysv ipc msgq functionsRich Felker2011-04-062-2/+2
|
* fix (hopefully) statvfs breakage on x86_64 that resulted from fixing i386...Rich Felker2011-04-052-2/+10
|
* document more changesRich Felker2011-04-051-0/+2
|
* new framework to inhibit thread cancellation when neededRich Felker2011-04-053-5/+17
| | | | | | | with these small changes, libc functions which need to call functions which are cancellation points, but which themselves must not be cancellation points, can use the CANCELPT_INHIBIT and CANCELPT_RESUME macros to temporarily inhibit all cancellation.
* add ip6 pktinfo stuff for x86_64Rich Felker2011-04-051-0/+12
| | | | these defs should probably all be moved out of bits and unified...
* add sysv ipc message queues (completely untested)Rich Felker2011-04-054-0/+58
|
* getopt.h is a GNU-getopt-specific header. always expose GNU functions.Rich Felker2011-04-051-2/+0
|
* add sysexits.h legacy headerRich Felker2011-04-051-0/+21
|
* implement the adjtime and adjtimex functions (nonstandard)Rich Felker2011-04-052-0/+34
|
* add getmntent_r interface (all of mntent is nonstandard anyway)Rich Felker2011-04-051-12/+17
|
* add some missing ipv6 stuffRich Felker2011-04-051-0/+12
|
* implement if_indextoname and if_nametoindex functionsRich Felker2011-04-052-0/+36
|
* add (nonstandard) cfmakeraw functionRich Felker2011-04-051-0/+12
|
* add pivot_root syscall wrapperRich Felker2011-04-051-0/+6
|
* add more legacy functions: setlinebuf and setbufferRich Felker2011-04-054-1/+17
|
* alternate name for syslog.hRich Felker2011-04-051-0/+1
|
* uncomment IP_PKTINFORich Felker2011-04-052-2/+2
| | | | | this was a hack leftover from testing before the initial check-in to git.
* support the nonstandard err.h interfacesRich Felker2011-04-052-0/+84
| | | | | | note that unlike the originals, these do not print the program name/argv[0] because we have not saved it anywhere. this could be changed in __libc_start_main if desired.
* release notes for next bugfix releaseRich Felker2011-04-051-0/+14
|
* fix misaligned read on early string termination in strchrRich Felker2011-04-051-1/+2
| | | | | | this could actually cause rare crashes in the case where a short string is located at the end of a page and the following page is not readable, and in fact this was seen in gcc compiling certain files.
* fix overflow in printf %N$ argument handlingRich Felker2011-04-051-2/+2
|
* fix various floating point rounding and formatting errors in *printfRich Felker2011-04-051-17/+25
|
* release notes for 0.7.6 bugfix release v0.7.6Rich Felker2011-04-041-0/+24
|
* fix rare but nasty under-allocation bug in malloc with large requestsRich Felker2011-04-041-1/+1
| | | | | | | | | the bug appeared only with requests roughly 2*sizeof(size_t) to 4*sizeof(size_t) bytes smaller than a multiple of the page size, and only for requests large enough to be serviced by mmap instead of the normal heap. it was only ever observed on 64-bit machines but presumably could also affect 32-bit (albeit with a smaller window of opportunity).
* simplify vdprintf implementation greatly based on recent vfprintf changesRich Felker2011-04-041-5/+2
| | | | | | | since vfprintf will provide a temporary buffer in the case where the target FILE has a zero buffer size, don't bother setting up a real buffer for vdprintf. this also allows us to skip the call to fflush since we know everything will be written out before vfprintf returns.
* use a local temp buffer for unbuffered streams in vfprintfRich Felker2011-04-042-0/+14
| | | | | | | | | this change makes it so most calls to fprintf(stderr, ...) will result in a single writev syscall, as opposed to roughly 2*N syscalls (and possibly more) where N is the number of format specifiers. in principle we could use a much larger buffer, but it's best not to increase the stack requirements too much. most messages are under 80 chars.
* fix nl_langinfo to actually use the existing, correct internal versionRich Felker2011-04-032-15/+5
|
* make ualarm actually work (obsolete function removed from SUS)Rich Felker2011-04-031-4/+9
|
* fix various bugs in strtold:Rich Felker2011-04-031-10/+13
| | | | | | | | | | | 0e10000000000000000000000000000000 was setting ERANGE exponent char e/p was considered part of the match even if not followed by a valid decimal value "1e +10" was parsed as "1e+10" hex digits were misinterpreted as 0..5 instead of 10..15
* fix serious bug in strchr - char signednessRich Felker2011-04-031-9/+11
| | | | | | search for bytes with high bit set was giving (potentially dangerous) wrong results. i've tested, cleaned up, and hopefully sped up this function now.
* prototype getdtablesize (nonstandard function)Rich Felker2011-04-031-0/+1
|
* add setresuid/setresgid functions (nonstandard)Rich Felker2011-04-033-0/+22
|
* pthread_create need not set errnoRich Felker2011-04-031-1/+1
|
* fix statvfs syscalls (missing size argument)Rich Felker2011-04-033-3/+3
|
* block all signals during rsyscallRich Felker2011-04-031-4/+9
| | | | | otherwise a signal handler could see an inconsistent and nonconformant program state where different threads have different uids/gids.
