[LTP] [PATCH v2 3/4] syscalls/prctl04: Allow rt_sigprocmask in the syscall filter

[Petr Vorel]

Hi Tudor,

> Some libcs (e.g. Musl) call rt_sigprocmask as part of their fork

When tested on lastest update Alpine with 1.2.3 it in both cases fails:

prctl04.c:205: TPASS: SECCOMP_MODE_FILTER doesn't permit exit()
prctl04.c:207: TFAIL: SECCOMP_MODE_FILTER doesn't permit exit()

What can be wrong?

@Yang Xu: Also this test (written in new API) should use tst_reinit()

Kind regards,
