The design strategy is to extend the existing tun/tap testing infrastructure to support this new use-case, rather than introducing a new or parallel framework. This allows for better integration and re-use of existing test logic. --- v1 -> v2: - Addresse sporadic failures due to too early send. - Refactor environment address assign helper function. - Fix incorrect argument passing in build packet functions. v1: https://lore.kernel.org/netdev/cover.1763345426.git.xudu@redhat.com/ Xu Du (8): selftest: tun: Format tun.c existing code selftest: tun: Introduce tuntap_helpers.h header for TUN/TAP testing selftest: tun: Refactor tun_delete to use tuntap_helpers selftest: tap: Refactor tap test to use tuntap_helpers selftest: tun: Add helpers for GSO over UDP tunnel selftest: tun: Add test for sending gso packet into tun selftest: tun: Add test for receiving gso packet from tun selftest: tun: Add test data for success and failure paths tools/testing/selftests/net/tap.c | 287 +----- tools/testing/selftests/net/tun.c | 917 ++++++++++++++++++- tools/testing/selftests/net/tuntap_helpers.h | 608 ++++++++++++ 3 files changed, 1530 insertions(+), 282 deletions(-) create mode 100644 tools/testing/selftests/net/tuntap_helpers.h base-commit: 7b8e9264f55a9c320f398e337d215e68cca50131 -- 2.49.0
