*	fix remaining IPC_64 issue (shmctl)	Rich Felker	2012-09-22	2	-4/+2
\| \| \| \|	also cleanup cruft related to the issue
*	fix IPC_64 in msgctl too	Rich Felker	2012-09-22	2	-6/+2
\|
*	fix broken semctl on systems that don't use IPC_64 flag	Rich Felker	2012-09-22	1	-2/+6
\| \| \| \| \|	not tested on mips and arm; they may still be broken. x86_64 should be ok now.
*	overhaul pthread cancellation	Rich Felker	2011-04-17	2	-12/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.
*	numerous fixes to sysv ipc	Rich Felker	2011-04-13	3	-5/+5
\| \| \| \| \| \| \| \| \| \|	some of these definitions were just plain wrong, others based on outdated ancient "non-64" versions of the kernel interface. as much as possible has now been moved out of bits/* these changes break abi (the old abi for these functions was wrong), but since they were not working anyway it can hardly matter.
*	consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefix	Rich Felker	2011-04-06	11	-11/+11
\|
*	fix incorrect (and conflicting on LP64 archs) types for sysv ipc msgq functions	Rich Felker	2011-04-06	1	-1/+1
\|
*	add sysv ipc message queues (completely untested)	Rich Felker	2011-04-05	4	-0/+58
\|
*	global cleanup to use the new syscall interface	Rich Felker	2011-03-20	7	-14/+14
\|
*	fixed missing cast in the non-i386 version of shmat (preparation for ports)	Rich Felker	2011-02-13	1	-1/+1

*	initial check-in, version 0.5.0 v0.5.0	Rich Felker	2011-02-12	9	-0/+118
