From: Jiri Benc Date: Tue, 8 Oct 2019 13:10:44 +0000 (+0200) Subject: selftests/bpf: Set rp_filter in test_flow_dissector X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fd418b01fe26c2430b1091675cceb3ab2b52e1e0;p=linux.git selftests/bpf: Set rp_filter in test_flow_dissector Many distributions enable rp_filter. However, the flow dissector test generates packets that have 1.1.1.1 set as (inner) source address without this address being reachable. This causes the selftest to fail. The selftests should not assume a particular initial configuration. Switch off rp_filter.
