From: Tanner Love <tannerlove.kernel@gmail.com> Date: Mon, 22 Jun 2020 13:43:24 -0400 > From: tannerlove <tannerlove@google.com> > > Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add > new rxtimestamp.sh wrapper script, so that the test runs isolated > from background traffic in a private network namespace. > > Also ignore failures of test case #6 by default. This case verifies > that a receive timestamp is not reported if timestamp reporting is > enabled for a socket, but generation is disabled. Receive timestamp > generation has to be enabled globally, as no associated socket is > known yet. A background process that enables rx timestamp generation > therefore causes a false positive. Ntpd is one example that does. > > Add a "--strict" option to cause failure in the event that any test > case fails, including test #6. This is useful for environments that > are known to not have such background processes. > > Tested: > make -C tools/testing/selftests TARGETS="net" run_tests > > Signed-off-by: Tanner Love <tannerlove@google.com> > Acked-by: Willem de Bruijn <willemb@google.com> Applied, thanks.
