Subject: [PATCH bpf-next v4 1/5] selftests/bpf: test_sockmap, check test failure
Date: Thu, 31 May 2018 13:42:36 +0900	[thread overview]
Message-ID: <20180531044240.796-2-bhole_prashant_q7@lab.ntt.co.jp> (raw)
In-Reply-To: <20180531044240.796-1-bhole_prashant_q7@lab.ntt.co.jp>

Test failures are not identified because exit code of RX/TX threads
is not checked. Also threads are not returning correct exit code.

- Return exit code from threads depending on test execution status
- In main thread, check the exit code of RX/TX threads
- Skip error checking for corked tests as they are expected to timeout

Fixes: 16962b2404ac ("bpf: sockmap, add selftests")
