In "bpf: Disallow freplace on XDP with mismatched xdp_has_frags values" [1], this XDP test is suggested to add to xdp.py. 1. Verify the failure of updating frag-capable prog with non-frag-capable prog, when the frag-capable prog attaches to mtu=9k driver. The test has been verified against Mellanox CX6 and Intel 82599ES NICs. With dropping other tests, here is the test log. # ethtool -i eth0 driver: mlx5_core version: 6.19.0-061900-generic # NETIF=eth0 python3 xdp.py TAP version 13 1..1 ok 1 xdp.test_xdp_native_update_mb_to_sb # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0 # ethtool -i eth0 driver: ixgbe version: 6.19.0-061900-generic # NETIF=eth0 python3 xdp.py TAP version 13 1..1 # CMD: ip link set dev eth0 xdpdrv obj /path/to/tools/testing/selftests/net/lib/xdp_dummy.bpf.o sec xdp.frags # EXIT: 2 # STDERR: RTNETLINK answers: Invalid argument ok 1 xdp.test_xdp_native_update_mb_to_sb # SKIP device does not support multi-buffer XDP # Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 error:0 Signed-off-by: Leon Hwang <leon.huangfu@shopee.com> Link: https://patch.msgid.link/20260406072655.368173-1-leon.huangfu@shopee.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
