2022-08-23	bpf, selftests: Test BPF_FLOW_DISSECTOR_CONTINUE	Shmulik Ladkani	1	-0/+8
	The dissector program returns BPF_FLOW_DISSECTOR_CONTINUE (and avoids setting skb->flow_keys or last_dissection map) in case it encounters IP packets whose (outer) source address is 127.0.0.127. Additional test is added to prog_tests/flow_dissector.c which sets this address as test's pkk.iph.saddr, with the expected retval of BPF_FLOW_DISSECTOR_CONTINUE. Also, legacy test_flow_dissector.sh was similarly augmented.

2020-01-27	selftests/bpf: Add test based on port range for BPF flow dissector	Yoshiki Komachi	1	-0/+14
	Add a simple test to make sure that a filter based on specified port range classifies packets correctly.

2019-10-20	Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net	David S. Miller	1	-0/+3
	Several cases of overlapping changes which were for the most part trivially resolvable. Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-08	selftests/bpf: Set rp_filter in test_flow_dissector	Jiri Benc	1	-0/+3
	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.

2018-11-10	selftests/bpf: rename flow dissector section to flow_dissector	Stanislav Fomichev	1	-1/+1
	Makes it compatible with the logic that derives program type from section name in libbpf_prog_type_by_name. Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2018-09-14	selftests/bpf: test bpf flow dissection	Petar Penkov	1	-0/+115
	Adds a test that sends different types of packets over multiple tunnels and verifies that valid packets are dissected correctly. To do so, a tc-flower rule is added to drop packets on UDP src port 9, and packets are sent from ports 8, 9, and 10. Only the packets on port 9 should be dropped. Because tc-flower relies on the flow dissector to match flows, correct classification demonstrates correct dissection. Also add support logic to load the BPF program and to inject the test packets.
