32-bit architectures implementing 64BIT_TIME and COMPAT_32BIT_TIME need to have the traditional semtimedop() behavior with 32-bit timestamps for sys_ipc() by calling compat_ksys_semtimedop(), while those that are not yet converted need to keep using ksys_semtimedop() like 64-bit architectures do. Note that I chose to not implement a new SEMTIMEDOP64 function that corresponds to the new sys_semtimedop() with 64-bit timeouts. The reason here is that sys_ipc() should no longer be used for new system calls, and libc should just call the semtimedop syscall directly. One open question remain to whether we want to completely avoid the sys_ipc() system call for architectures that do not yet have all the individual calls as they get converted to 64-bit time_t. Doing that would require adding several extra system calls on m68k, mips, powerpc, s390, sh, sparc, and x86-32. Signed-off-by: Arnd Bergmann <arnd@arndb.de> |
