2011-02-18support the ugly and deprecated ucontext and sigcontext header stuff...Rich Felker-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...
2011-02-18add pthread_atfork interfaceRich Felker-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.
2011-02-18major improvements to temp file name generatorRich Felker-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.
2011-02-18reformat mkstemp like mkdtempRich Felker-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.
2011-02-17add portable lchown (trivial to support and a few ancient things want it..)Rich Felker-0/+10
2011-02-17prepare WHATSNEW for releasev0.6.0Rich Felker-1/+1

2011-02-17avoid deleting the lib/empty fileRich Felker-1/+1
2011-02-17reorganize pthread data structures and move the definitions to alltypes.hRich Felker-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.
2011-02-17new solution for empty lib dir (old one had some problems)Rich Felker-7/+5
2011-02-17improve Makefile handling of git checkouts with missing lib/ and config.makRich Felker-4/+8
2011-02-17make daemon try the operations that might fail before fork rather than afterRich Felker-12/+10
2011-02-17daemon should check for failures and return -1Rich Felker-5/+8
2011-02-17don't compare elements with themselves during qsort.Rich Felker-1/+1
this is actually a workaround for a bug in gcc, whereby it asserts inequality of the keys being compared...
2011-02-16ucontext is no longer in the standard, so use gnu-friendly struct nameRich Felker-2/+2
note that this header is still bogus and needs a lot of work and factoring into arch-dependent parts...
2011-02-16some gnu software wrongly uses "struct siginfo" instead of siginfo_t...Rich Felker-0/+1
2011-02-16add to pthread.h: pthread_mutex_timedlock and sched.h, time.hRich Felker-1/+3

2011-02-16patch by njk, simplifies thread register initialization for x86_64Rich Felker-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.

2011-02-15remove standalone syscall cruftRich Felker-32/+2
this was originally written for an early draft of the library where non-standard functions would reside in a static library separate from the shared libc.so, which would implement a pure standard. the idea was not to depend on an implementation-dependent __syscall_ret function in the main libc. but it turned out to be better to put everything in a single library for both static and dynamic linking uses, and thus the (incomplete) remnants of this feature were just enlarging the source and binary.
