From 2cca35f5dd78b9f8297c879c5db5ab137c5d86c3 Mon Sep 17 00:00:00 2001 From: Marcin Szycik Date: Tue, 9 Apr 2024 17:45:44 +0200 Subject: ice: Fix checking for unsupported keys on non-tunnel device 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") Reviewed-by: Michal Swiatkowski Signed-off-by: Marcin Szycik Reviewed-by: Jacob Keller Tested-by: Sujai Buvaneswaran Signed-off-by: Tony Nguyen --- drivers/net/ethernet/intel/ice/ice_tc_lib.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'drivers') diff --git a/drivers/net/ethernet/intel/ice/ice_tc_lib.c b/drivers/net/ethernet/intel/ice/ice_tc_lib.c index bcbcfc67e5606..688ccb0615ab9 100644 --- a/drivers/net/ethernet/intel/ice/ice_tc_lib.c +++ b/drivers/net/ethernet/intel/ice/ice_tc_lib.c @@ -1489,7 +1489,10 @@ ice_parse_cls_flower(struct net_device *filter_dev, struct ice_vsi *vsi, (BIT_ULL(FLOW_DISSECTOR_KEY_ENC_IPV4_ADDRS) | BIT_ULL(FLOW_DISSECTOR_KEY_ENC_IPV6_ADDRS) | BIT_ULL(FLOW_DISSECTOR_KEY_ENC_KEYID) | - BIT_ULL(FLOW_DISSECTOR_KEY_ENC_PORTS))) { + BIT_ULL(FLOW_DISSECTOR_KEY_ENC_PORTS) | + BIT_ULL(FLOW_DISSECTOR_KEY_ENC_IP) | + BIT_ULL(FLOW_DISSECTOR_KEY_ENC_OPTS) | + BIT_ULL(FLOW_DISSECTOR_KEY_ENC_CONTROL))) { NL_SET_ERR_MSG_MOD(fltr->extack, "Tunnel key used, but device isn't a tunnel"); return -EOPNOTSUPP; } else { -- cgit 1.2.3-korg
