We sometimes need to compare whole structures in an assert. It is possible to use the existing macros on each field, but when the whole structure has to be checked, it is more convenient to simply compare the whole structure memory Add a dedicated assert macro, ASSERT_MEMEQ, to allow bare memory comparision The output generated by this new macro looks like the following: [...] run_tests_skb_less:FAIL:returned flow keys unexpected memory mismatch actual: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 expected: 0E 00 3E 00 DD 86 01 01 00 06 86 DD 50 00 90 1F 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 [...] Acked-by: Stanislav Fomichev <sdf@fomichev.me> Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com> Link: https://lore.kernel.org/r/20241120-flow_dissector-v3-1-45b46494f937@bootlin.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
