flow_dissector: add support for ingress ifindex dissection

2019-06-19T14:09:21+00:00

Add new key meta that contains ingress ifindex value and add a function to dissect this from skb. The key and function is prepared to cover other potential skb metadata values dissection. Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

net: ethtool: Allow matching on vlan DEI bit

2019-06-12T17:09:56+00:00

Using ethtool, users can specify a classification action matching on the full vlan tag, which includes the DEI bit (also previously called CFI). However, when converting the ethool_flow_spec to a flow_rule, we use dissector keys to represent the matching patterns. Since the vlan dissector key doesn't include the DEI bit, this information was silently discarded when translating the ethtool flow spec in to a flow_rule. This commit adds the DEI bit into the vlan dissector key, and allows propagating the information to the driver when parsing the ethtool flow spec.

flow_dissector: switch kernel context to struct bpf_flow_dissector

2019-04-23T16:36:33+00:00

struct bpf_flow_dissector has a small subset of sk_buff fields that flow dissector BPF program is allowed to access and an optional pointer to real skb. Real skb is used only in bpf_skb_load_bytes helper to read non-linear data. The real motivation for this is to be able to call flow dissector from eth_get_headlen context where we don't have an skb and need to dissect raw bytes.

net/flow_dissector: correct comments on enum flow_dissector_key_id

2018-11-30T21:21:52+00:00

There are no such structs flow_dissector_key_flow_vlan or flow_dissector_key_flow_tags, the actual structs used are struct flow_dissector_key_vlan and struct flow_dissector_key_tags. So correct the comments against FLOW_DISSECTOR_KEY_VLAN, FLOW_DISSECTOR_KEY_FLOW_LABEL and FLOW_DISSECTOR_KEY_CVLAN to refer to those. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

flow_dissector: allow dissection of tunnel options from metadata

2018-08-07T19:22:14+00:00

Allow the existing 'dissection' of tunnel metadata to 'dissect' options already present in tunnel metadata. This dissection is controlled by a new dissector key, FLOW_DISSECTOR_KEY_ENC_OPTS. This dissection only occurs when skb_flow_dissect_tunnel_info() is called, currently only the Flower classifier makes that call. So there should be no impact on other users of the flow dissector. This is in preparation for allowing the flower classifier to match on Geneve options.
