Eric W. Biederman 55a3235fc7 signal: Properly deliver SIGILL from uprobes ... For userspace to tell the difference between a random signal and an exception, the exception must include siginfo information. Using SEND_SIG_FORCED for SIGILL is thus wrong, and it will result in userspace seeing si_code == SI_USER (like a random signal) instead of si_code == SI_KERNEL or a more specific si_code as all exceptions deliver. Therefore replace force_sig_info(SIGILL, SEND_SIG_FORCE, current) with force_sig(SIG_ILL, current) which gets this right and is shorter and easier to type.
