selftests/net: Add trace events matching to tcp_aoSetup trace points, add a new ftrace instance in order to not interferewith the rest of the system, filtering by net namespace cookies.Raise a new background thread that parses trace_pipe, matches them withthe list of expected events.Wiring up trace events to selftests provides another insight if there isanything unexpected happining in the tcp-ao code (i.e. key rotation whenit's not expected).Note: in real programs libtraceevent should be used instead of thismanual labor of setting ftrace up and parsing. I'm not using it hereas I don't want to have an .so library dependency that one would have tobring into VM or DUT (Device Under Test). Please, don't copy it overinto any real world programs, that aren't tests.Signed-off-by: Dmitry Safonov <0x7f454c46@gmail.com>Link: https://patch.msgid.link/20240823-tcp-ao-selftests-upd-6-12-v4-8-05623636fe8c@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/tcp_ao/config

selftests: tcp_ao: add a config fileStill a bit unclear whether each directory should have its ownconfig file, but assuming they should lets add one for tcp_ao.The following tests still fail with this config in place: - rst_ipv4, - rst_ipv6, - bench-lookups_ipv6.other 21 pass.Fixes: d11301f65977 ("selftests/net: Add TCP-AO ICMPs accept test")Reviewed-by: Dmitry Safonov <0x7f454c46@gmail.com>Link: https://lore.kernel.org/r/20240124192550.1865743-1-kuba@kernel.orgSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/tcp_ao/config
