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. Changes in v6: 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 # SKIP: veth0: set IP address # 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: # PASS: veth0: Restore feature rx-gro-list to initial state off # PASS: veth0: Turned off feature: rx-udp-gro-forwarding # 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 (2): selftests: net: Create veth pair for testing in networkless kernel selftests: net: Add on/off checks for non-fixed features of interface tools/testing/selftests/net/netdevice.sh | 55 +++++++++++++++++++++++- 1 file changed, 53 insertions(+), 2 deletions(-) -- 2.34.1
