From 779e422d11985e408fc148f0cca0f4b403f6c5fa Mon Sep 17 00:00:00 2001 From: Jakub Sitnicki Date: Mon, 24 Feb 2020 14:53:26 +0100 Subject: selftests/bpf: Run reuseport tests only with supported socket types MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SOCKMAP and SOCKHASH map types can be used with reuseport BPF programs but don't support yet storing UDP sockets. Instead of marking UDP tests with SOCK{MAP,HASH} as skipped, don't run them at all. Skipped test might signal that the test environment is not suitable for running the test, while in reality the functionality is not implemented in the kernel yet. Before: sh# ./test_progs -t select_reuseport … #40 select_reuseport:OK Summary: 1/126 PASSED, 30 SKIPPED, 0 FAILED After: sh# ./test_progs -t select_reuseport … #40 select_reuseport:OK Summary: 1/98 PASSED, 2 SKIPPED, 0 FAILED The remaining two skipped tests are SYN cookies tests, which will be addressed in the subsequent patch.
