This allows for better integration and re-use of existing test logic. --- v5 -> v6: - Fix the Makefile format errors. v5: https://lore.kernel.org/all/cover.1768800198.git.xudu@redhat.com/ - Refactor the rtnetlink utilities to use YNL. - Use Geneve tunnel instead of VXLAN tunnel. - Revert tap refactor as YNL lacks macvtap support. v4: https://lore.kernel.org/netdev/cover.1767597114.git.xudu@redhat.com/ - Rebase onto the latest net-next tree to resolve merge conflicts. v3: https://lore.kernel.org/netdev/cover.1767580224.git.xudu@redhat.com/ - Re-send the patch series becasue Patchwork don't update them. v2: https://lore.kernel.org/netdev/cover.1767074545.git.xudu@redhat.com/ - 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 (7): 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: 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/Makefile | 16 +- tools/testing/selftests/net/tun.c | 898 ++++++++++++++++++- tools/testing/selftests/net/tuntap_helpers.h | 390 ++++++++ 3 files changed, 1265 insertions(+), 39 deletions(-) create mode 100644 tools/testing/selftests/net/tuntap_helpers.h base-commit: c5e7b1d1cc8a6cb8b709eef34c93a9458427ab2e -- 2.52.0
