Subject: [Intel-wired-lan] [PATCH iwl-net] ice: Fix checking for unsupported keys on non-tunnel device
Date: Tue, 9 Apr 2024 17:45:44 +0200 [thread overview]
Message-ID: <20240409154543.8181-2-marcin.szycik@linux.intel.com> (raw)
Add missing FLOW_DISSECTOR_KEY_ENC_* checks to TC flower filter parsing.
Without these checks, it would be possible to add filters with tunnel
options on non-tunnel devices. enc_* options are only valid for tunnel
devices.
Example:
devlink dev eswitch set $PF1_PCI mode switchdev
echo 1 > /sys/class/net/$PF1/device/sriov_numvfs
tc qdisc add dev $VF1_PR ingress
ethtool -K $PF1 hw-tc-offload on
tc filter add dev $VF1_PR ingress flower enc_ttl 12 skip_sw action drop
Fixes: 9e300987d4a8 ("ice: VXLAN and Geneve TC support")
