Bug Description
== SRU Justification ==
The TRACE_syscall.
[ RUN ] TRACE_syscall.
seccomp_
TRACE_syscall.
[ FAIL ] TRACE_syscall.
== Fix ==
* ed5f1326 (selftests/seccomp: Enhance per-arch ptrace syscall skip tests)
This patch can be cherry-picked into B/C, and it's already in Disco.
The ptrace_
== Test ==
Patch tested with different arch (amd64 / power8 / arm64 / i386), the new test will pass on them except for PowerPC.
Although the faked (bug 1829363) and errno (bug 1829359) test will fail on PowerPC, it's actually helping us to nail down a real issue in our kernel.
== Regression Potential ==
Low, changes limited to the testing tool in the kernel.
