rofl0r	2b47a7aff2	semctl: fix UB causing crashes on powerpc it's UB to fetch variadic args when none are passed, and this caused real crashes on ppc due to its calling convention, which defines that for variadic functions aggregate types be passed as pointers. the assignment caused that pointer to get dereferenced, resulting in a crash.	12 years ago

Rich Felker	289294220f	fix type of semctl variadic argument 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.	13 years ago
Rich Felker	cccc13221d	fix IPC_64 in msgctl too	14 years ago
Rich Felker	fce46bf980	fix broken semctl on systems that don't use IPC_64 flag not tested on mips and arm; they may still be broken. x86_64 should be ok now.	14 years ago
Rich Felker	07e865cc5a	numerous fixes to sysv ipc some of these definitions were just plain wrong, others based on outdated ancient "non-64" versions of the kernel interface.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.	15 years ago
Rich Felker	c2cd25bff8	consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefix	15 years ago
Rich Felker	aa398f56fa	global cleanup to use the new syscall interface	15 years ago
