This ensures that it will be possible for a VCAP rule to distinguish IPv6 frames from non-IP frames, as the IS0 keyset usually selected for the IPv6 traffic class in (7TUPLE) does not offer a key that specifies IPv6 directly: only non-IPv4.

2023-01-27lan966x: execute xdp_do_flush() before napi_complete_done()Magnus Karlsson1-3/+3
Make sure that xdp_do_flush() is always executed before napi_complete_done(). This is important for two reasons. First, a redirect to an XSKMAP assumes that a call to xdp_do_redirect() from napi context X on CPU Y will be followed by a xdp_do_flush() from the same napi context and CPU. This is not guaranteed if the napi_complete_done() is executed before xdp_do_flush(), as it tells the napi logic that it is fine to schedule napi context X on another CPU. Details from a production system triggering this bug using the veth driver can be found following the first link below. The second reason is that the XDP_REDIRECT logic in itself relies on being inside a single NAPI instance through to the xdp_do_flush() call for RCU protection of all in-kernel data structures. Details can be found in the second link below.

2023-01-20net: microchip: sparx5: add support for DSCP rewriteDaniel Machon4-0/+124
Add support for DSCP rewrite in Sparx5 driver. On egress DSCP is rewritten from either classified DSCP, or frame DSCP. Classified DSCP is determined by the Analyzer Classifier on ingress, and is mapped from classified QoS class and DP level. Classification of DSCP is by default enabled for all ports. It is required that DSCP is trusted for the egress port *and* rewrite table is not empty, in order to rewrite DSCP based on classified DSCP, otherwise DSCP is always rewritten from frame DSCP. classified_dscp = qos_dscp_map[8 * dp_level + qos_class]; if (active_mappings && dscp_is_trusted) rewritten_dscp = classified_dscp else rewritten_dscp = frame_dscp To rewrite DSCP to 20 for any frames with priority 7: $ dcb apptrust set dev eth0 order dscp $ dcb rewr add dev eth0 7:20 <-- not in iproute2/dcb yet Signed-off-by: Daniel Machon <[email protected]> Signed-off-by: David S.

2023-01-20net: microchip: sparx5: add support for PCP rewriteDaniel Machon4-14/+191
Add support for rewrite of PCP and DEI, based on classified Quality of Service (QoS) class and Drop-Precedence (DP) level. The DCB rewrite table is queried for mappings between priority and PCP/DEI. The classified DP level is then encoded in the DEI bit, if a mapping for DEI exists. Sparx5 has four DP levels, where by default, 0 is mapped to DE0 and 1-3 are mapped to DE1. If a mapping exists where DEI=1, then all classified DP levels mapped to DE1 will set the DEI bit. The other way around for DEI=0. Effectively, this means that the tagged DEI bit will reflect the DP level for any mappings where DEI=1. Map priority=1 to PCP=1 and DEI=1: $ dcb rewr add dev eth0 pcp-prio 1:1de Map priority=7 to PCP=2 and DEI=0 $ dcb rewr add dev eth0 pcp-prio 7:2nd Also, sparx5_dcb_ieee_dscp_setdel() has been refactored, to work for both APP and rewrite entries.

When adding a flower filter it is now checked that the filter contains a goto action to one of the IS2 VCAP lookups, except for the last lookup which may omit this goto action.

2023-01-16net: microchip: vcap api: Use src and dst chain id to chain VCAP lookupsSteen Hegelund6-84/+92
This adds both the source and destination chain id to the information kept for enabled port lookups. This allows enabling and disabling a chain of lookups by walking the chain information for a port. This changes the way that VCAP lookups are enabled from userspace: instead of one matchall rule that enables all the 4 Sparx5 IS2 lookups, you need a matchall rule per lookup. In practice that is done by adding one matchall rule in chain 0 to goto IS2 Lookup 0, and then for each lookup you add a rule per lookup (low priority) that does a goto to the next lookup chain. Examples: If you want IS2 Lookup 0 to be enabled you add the same matchall filter as before: tc filter add dev eth12 ingress chain 0 prio 1000 handle 1000 matchall \ skip_sw action goto chain 8000000 If you also want to enable lookup 1 to 3 in IS2 and chain them you need to add the following matchall filters: tc filter add dev eth12 ingress chain 8000000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8100000 tc filter add dev eth12 ingress chain 8100000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8200000 tc filter add dev eth12 ingress chain 8200000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8300000 Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: Steen Hegelund <[email protected]> Signed-off-by: David S.

2022-12-06net: lan966x: Add ptp trap rulesHoratiu Vultur5-23/+265
Currently lan966x, doesn't allow to run PTP over interfaces that are part of the bridge. The reason is when the lan966x was receiving a PTP frame (regardless if L2/IPv4/IPv6) the HW it would flood this frame. Now that it is possible to add VCAP rules to the HW, such to trap these frames to the CPU, it is possible to run PTP also over interfaces that are part of the bridge.
