2014-10-31fix uninitialized mode variable in openat functionRich Felker-1/+1
this was introduced in commit 2da3ab1382ca8e39eb1e4428103764a81fba73d3 as an oversight while making the variadic argument access conditional.
2014-10-30fix invalid access by openat to possibly-missing variadic mode argumentRich Felker-4/+8
the mode argument is only required to be present when the O_CREAT or O_TMPFILE flag is used.

2011-04-17overhaul pthread cancellationRich Felker-5/+1
this patch improves the correctness, simplicity, and size of cancellation-related code. modulo any small errors, it should now be completely conformant, safe, and resource-leak free. the notion of entering and exiting cancellation-point context has been completely eliminated and replaced with alternative syscall assembly code for cancellable syscalls. the assembly is responsible for setting up execution context information (stack pointer and address of the syscall instruction) which the cancellation signal handler can use to determine whether the interrupted code was in a cancellable state. these changes eliminate race conditions in the previous generation of cancellation handling code (whereby a cancellation request received just prior to the syscall would not be processed, leaving the syscall to block, potentially indefinitely), and remedy an issue where non-cancellable syscalls made from signal handlers became cancellable if the signal handler interrupted a cancellation point. x86_64 asm is untested and may need a second try to get it right.
