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() https://lore.kernel.org/ltp/70476626-2c7a-fcd6-4cf4-de7cbd572f99@fujitsu.com/T/#mb3e34713dd15f2050ec2dc01615fefb7ee66c880 Kind regards, Petr -- Mailing list info: https://lists.linux.it/listinfo/ltp
