Greetings: Welcome to v4.
This series fixes netdevsim to correctly set the NAPI ID on the skb. This is helpful for writing tests around features that use SO_INCOMING_NAPI_ID. In addition to the netdevsim fix in patch 1, patches 2 & 3 do some self test refactoring and add a test for NAPI IDs. The test itself (patch 3) introduces a C helper because apparently python doesn't have socket.SO_INCOMING_NAPI_ID. Thanks, Joe v4: - Updated the macro guard in patch 2 - Removed the remote deploy from patch 3 v3: https://lore.kernel.org/netdev/20250418013719.12094-1-jdam...@fastly.com/ - Dropped patch 3 from v2 as it is no longer necessary. - Patch 3 from this series (which was patch 4 in the v2) - Sorted .gitignore alphabetically - added cfg.remote_deploy so the test supports real remote machines - Dropped the NetNSEnter as it is unnecessary - Fixed a string interpolation issue that Paolo hit with his Python version v2: https://lore.kernel.org/netdev/20250417013301.39228-1-jdam...@fastly.com/ - No longer an RFC - Minor whitespace change in patch 1 (no functional change). - Patches 2-4 new in v2 rfcv1: https://lore.kernel.org/netdev/20250329000030.39543-1-jdam...@fastly.com/ Joe Damato (3): netdevsim: Mark NAPI ID on skb in nsim_rcv selftests: drv-net: Factor out ksft C helpers selftests: drv-net: Test that NAPI ID is non-zero drivers/net/netdevsim/netdev.c | 2 + .../testing/selftests/drivers/net/.gitignore | 1 + tools/testing/selftests/drivers/net/Makefile | 6 +- tools/testing/selftests/drivers/net/ksft.h | 56 +++++++++++++ .../testing/selftests/drivers/net/napi_id.py | 23 +++++ .../selftests/drivers/net/napi_id_helper.c | 83 +++++++++++++++++++ .../selftests/drivers/net/xdp_helper.c | 49 +---------- 7 files changed, 172 insertions(+), 48 deletions(-) create mode 100644 tools/testing/selftests/drivers/net/ksft.h create mode 100755 tools/testing/selftests/drivers/net/napi_id.py create mode 100644 tools/testing/selftests/drivers/net/napi_id_helper.c base-commit: cd7276ecac9c64c80433fbcff2e35aceaea6f477 -- 2.43.0
