Previously we did not check the flow dissector against a list of allowed and supported flow key dissectors. This patch introduces such a list and correctly rejects unsupported flow keys. Fixes: 43f84b72c50d ("nfp: add metadata to each flow offload") Signed-off-by: Pieter Jansen van Vuuren <pieter.jansenvanvuu...@netronome.com> Reviewed-by: Simon Horman <simon.hor...@netronome.com> Reviewed-by: Jakub Kicinski <jakub.kicin...@netronome.com> --- drivers/net/ethernet/netronome/nfp/flower/offload.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/drivers/net/ethernet/netronome/nfp/flower/offload.c b/drivers/net/ethernet/netronome/nfp/flower/offload.c index d396183108f7..a18b4d2b1d3e 100644 --- a/drivers/net/ethernet/netronome/nfp/flower/offload.c +++ b/drivers/net/ethernet/netronome/nfp/flower/offload.c @@ -44,6 +44,16 @@ #include "../nfp_net.h" #include "../nfp_port.h" +#define NFP_FLOWER_WHITELIST_DISSECTOR \ + (BIT(FLOW_DISSECTOR_KEY_CONTROL) | \ + BIT(FLOW_DISSECTOR_KEY_BASIC) | \ + BIT(FLOW_DISSECTOR_KEY_IPV4_ADDRS) | \ + BIT(FLOW_DISSECTOR_KEY_IPV6_ADDRS) | \ + BIT(FLOW_DISSECTOR_KEY_PORTS) | \ + BIT(FLOW_DISSECTOR_KEY_ETH_ADDRS) | \ + BIT(FLOW_DISSECTOR_KEY_VLAN) | \ + BIT(FLOW_DISSECTOR_KEY_IP)) + static int nfp_flower_xmit_flow(struct net_device *netdev, struct nfp_fl_payload *nfp_flow, u8 mtype) @@ -112,6 +122,9 @@ nfp_flower_calculate_key_layers(struct nfp_fl_key_ls *ret_key_ls, u8 key_layer; int key_size; + if (flow->dissector->used_keys & ~NFP_FLOWER_WHITELIST_DISSECTOR) + return -EOPNOTSUPP; + if (dissector_uses_key(flow->dissector, FLOW_DISSECTOR_KEY_ENC_CONTROL)) { struct flow_dissector_key_control *mask_enc_ctl = -- 2.14.1
