Same as initial tests, import verbatim from github.com/google/packetdrill, aside from: - update `source ./defaults.sh` path to adjust for flat dir - add SPDX headers - remove author statements if any - drop blank lines at EOF Same test process as previous tests. Both with and without debug mode. Recording the steps once: make mrproper vng --build \ --config tools/testing/selftests/net/packetdrill/config \ --config kernel/configs/debug.config vng -v --run . --user root --cpus 4 -- \ make -C tools/testing/selftests TARGETS=net/packetdrill run_tests Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Soham Chakradeo <sohamch@google.com> Link: https://patch.msgid.link/20241217185203.297935-2-sohamch.kernel@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
