Summary: With glibc 2.26, the open syscall is not used anymore as openat is favored. This causes the testcase to fail, which shows that openat is not handled correctly by the seccomp filter. This adds a testcase that tests both open and openat (needs to use direct syscalls on glibc 2.26 as calls to open would otherwise result in openat) and implements the proper handling for openat in the filter. BUG: 384651 Test Plan: Ran seccomp test before and after, now succeeds. Ran make install, screenlocker still works.
