This small series includes fixes for creation of veth pairs for networkless kernels & adds tests for turning the different network interface features on and off in selftests/net/netdevice.sh script. Tested using vng and compiles for network as well as networkless kernel. Changes in v8: Remove redundant variable initial_state as per feedback in v7. Changes in v7: https://lore.kernel.org/all/20240815105924.1389290-1-jain.abhinav177@xxxxxxxxx Create a third patch in the series to do SKIP -> XFAIL replacement. Add logic to incorporate XFAIL on setting IP address for veth pair. Changes in v6: https://lore.kernel.org/all/20240814191517.50466-1-jain.abhinav177@xxxxxxxxx Use XFAIL for ethtool operations that are unsupported instead of SKIP. Changes in v5: https://lore.kernel.org/all/20240808122452.25683-1-jain.abhinav177@xxxxxxxxx Rectify the syntax for ip add link. Fix the veth_created condition check. Changes in v4: https://lore.kernel.org/all/20240807175717.7775-1-jain.abhinav177@xxxxxxxxx Move veth creation/removal to the main shell script. Tested using vng on a networkless kernel and the script works, sample output below the changes. Changes in v3: https://lore.kernel.org/all/20240614113240.41550-1-jain.abhinav177@xxxxxxxxx Add a check for netdev, create veth pair for testing. Restore feature to its initial state. Changes in v2: https://lore.kernel.org/all/20240609132124.51683-1-jain.abhinav177@xxxxxxxxx Remove tail usage; use read to parse the features from temp file. v1: https://lore.kernel.org/all/20240606212714.27472-1-jain.abhinav177@xxxxxxxxx ``` # selftests: net: netdevice.sh # No valid network device found, creating veth pair # PASS: veth0: set interface up # PASS: veth0: set MAC address # XFAIL: veth0: set IP address unsupported for veth* # PASS: veth0: ethtool list features # PASS: veth0: Turned off feature: rx-checksumming # PASS: veth0: Turned on feature: rx-checksumming # PASS: veth0: Restore feature rx-checksumming to initial state on # Actual changes: # tx-checksum-ip-generic: off ... # PASS: veth0: Turned on feature: rx-udp-gro-forwarding # PASS: veth0: Restore feature rx-udp-gro-forwarding to initial state off # Cannot get register dump: Operation not supported # XFAIL: veth0: ethtool dump not supported # PASS: veth0: ethtool stats # PASS: veth0: stop interface ``` Abhinav Jain (3): selftests: net: Create veth pair for testing in networkless kernel selftests: net: Add on/off checks for non-fixed features of interface selftests: net: Use XFAIL for operations not supported by the driver tools/testing/selftests/net/netdevice.sh | 61 ++++++++++++++++++++++-- 1 file changed, 57 insertions(+), 4 deletions(-) -- 2.34.1
