H A D | syscall.c | bae1cd36 Thu Apr 29 04:14:51 CDT 2021 Sven Schnelle <svens@linux.ibm.com> s390/entry: add support for syscall stack randomization
This adds support for adding a random offset to the stack while handling syscalls. The patch uses get_tod_clock_fast() as this is considered good enough and has much less performance penalty compared to using get_random_int(). The patch also adds randomization in pgm_check_handler() as the sigreturn/rt_sigreturn system calls might be called from there.
