2014-01-08	fix type of semctl variadic argument	Rich Felker	-4/+10
	per POSIX, the variadic argument has type union semun, which may contain a pointer or int; the type read depends on the command being issued. this allows the userspace part of the implementation to be type-correct without requiring special-casing for different commands. the kernel always expects to receive the argument interpreted as unsigned long (or equivalently, a pointer), and does its own handling of extracting the int portion from the representation, as needed. this change fixes two possible issues: most immediately, reading the argument as a (signed) long and passing it to the syscall would perform incorrect sign-extension of pointers on the upcoming x32 target. the other possible issue is that some archs may use different (user-space) argument-passing convention for unions, preventing va_arg from correctly obtaining the argument when the type long (or even unsigned long or void *) is passed to it.
2012-09-22	fix IPC_64 in msgctl too	Rich Felker	-4/+0

2012-09-22	fix broken semctl on systems that don't use IPC_64 flag	Rich Felker	-2/+6
	not tested on mips and arm; they may still be broken. x86_64 should be ok now.
2011-04-13	numerous fixes to sysv ipc	Rich Felker	-1/+1
	some of these definitions were just plain wrong, others based on outdated ancient "non-64" versions of the kernel interface.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.
2011-04-06	consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefix	Rich Felker	-1/+1

2011-03-20	global cleanup to use the new syscall interface	Rich Felker	-2/+2

2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	-0/+18
