| H A D | syscall_wrapper.h | 766c6c1d Tue Dec 19 17:26:59 CST 2023 Linus Torvalds <torvalds@linux-foundation.org> posix-timers: Get rid of [COMPAT_]SYS_NI() uses
[ Upstream commit a4aebe936554dac6a91e5d091179c934f8325708 ]
Only the posix timer system calls use this (when the posix timer support
is disabled, which does not actually happen in any normal case), because
they had debug code to print out a warning about missing system calls.
Get rid of that special case, and just use the standard COND_SYSCALL
interface that creates weak system call stubs that return -ENOSYS for
when the system call does not exist.
This fixes a kCFI issue with the SYS_NI() hackery:
CFI failure at int80_emulation+0x67/0xb0 (target: sys_ni_posix_timers+0x0/0x70; expected type: 0xb02b34d9)
