Tony Nguyen says: ==================== ice: L2TPv3 offload support Wojciech Drewek says: Add support for dissecting L2TPv3 session id in flow dissector. Add support for this field in tc-flower and support offloading L2TPv3. Finally, add support for hardware offload of L2TPv3 packets based on session id in switchdev mode in ice driver. Example filter: # tc filter add dev $PF1 ingress prio 1 protocol ip \ flower \ ip_proto l2tp \ l2tpv3_sid 1234 \ skip_sw \ action mirred egress redirect dev $VF1_PR Changes in iproute2 are required to use the new fields. ICE COMMS DDP package is required to create a filter in ice. COMMS DDP package contains profiles of more advanced protocols. Without COMMS DDP package hw offload will not work, however sw offload will still work. ==================== Link: https://lore.kernel.org/r/20220908171644.1282191-1-anthony.l.nguyen@intel.comSigned-off-by:Paolo Abeni <pabeni@redhat.com>

All usages of the vport_ops struct have the .send field set to dev_queue_xmit or internal_dev_recv. Since most usages are set to dev_queue_xmit, the function hook should match the signature of dev_queue_xmit. The only call to vport_ops->send() is in net/openvswitch/vport.c and it throws away the return value. This mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. Reported-by:

Petr Machata says: ==================== mlxsw: Adjust QOS tests for Spectrum-4 testing Amit writes: Quality Of Service tests create congestion and verify the switch behavior. To create congestion, they need to have more traffic than the port can handle, so some of them force 1Gbps speed. The tests assume that 1Gbps speed is supported. Spectrum-4 ASIC will not support this speed in all ports, so to be able to run QOS tests there, some adjustments are required. Patch set overview: Patch #1 adjusts qos_ets_strict, qos_mc_aware and sch_ets tests. Patch #2 adjusts RED tests. Patch #3 extends devlink_lib to support querying maximum pool size. Patch #4 adds a test which can be used instead of qos_burst and do not assume that 1Gbps speed is supported. Patch #5 removes qos_burst test. ==================== Link: https://lore.kernel.org/r/cover.1663152826.git.petrm@nvidia.comSigned-off-by:

Add an equivalent test to qos_burst, the test's purpose is same, but the new test uses simpler topology and does not require forcing low speed. In addition, it can be run Spectrum-2 and not only Spectrum-3+. The idea is to use a shaper in order to limit the traffic and create congestion. qos_burst test uses small pool, sends many small packets, and verify that packets are not dropped, which means that many descriptors can be handled. This test should check the change that commit c864769a ("mlxsw: Configure descriptor buffers") pushed. Instead, the new test tries to use more than 85% of maximum supported descriptors. The idea is to use big pool (as much as the ASIC supports), such that the pool size does not limit the traffic, then send many small packets, which means that many descriptors are used, and check how many packets the switch can handle. The usage of shaper allows to run the test in all ASICs, regardless of the CPU abilities, as it is able to create the congestion with low rate of packets. Signed-off-by:

QOS tests create congestion and verify the switch behavior. To create congestion, they need to have more traffic than the port can handle, so some of them force 1Gbps speed. The tests assume that 1Gbps speed is supported, otherwise, they will fail. Spectrum-4 ASIC will not support this speed in all ports, so to be able to run the tests there, some adjustments are required. Use shapers to limit the traffic instead of forcing speed. Note that for several ports, the speed configuration is just for autoneg issues, so shaper is not needed instead. The tests already use ETS qdisc as a root and RED qdiscs as children. Add a new TBF shaper to limit the rate of traffic, and use it as a root qdisc, then save the previous hierarchy of qdiscs under the new TBF root. In some ASICs, the shapers do not limit the traffic as accurately as forcing speed. To make the tests stable, allow the backlog size to be up to +-10% of the threshold. The aim of the tests is to make sure that with backlog << threshold, there are no drops, and that packets are dropped somewhere in vicinity of the configured threshold. Signed-off-by:

Vladimir Oltean says: ==================== Remove label = "cpu" from DSA dt-bindings As explained in more detail in patch 1/3, label = "cpu" is not part of DSA's device tree bindings, yet we have some checks in the dt-schema for mt7530 which are written as if it was.

Vladimir Oltean authored
The fact that some DSA device trees use 'label = "cpu"' for the CPU port is nothing but blind cargo cult copying. The 'label' property was never part of the DSA DT bindings for anything except the user ports, where it provided a hint as to what name the created netdevs should use. DSA does use the "cpu" port label to identify a CPU port in dsa_port_parse(), but this is only for non-OF code paths (platform data). The proper way to identify a CPU port is to look at whether the 'ethernet' phandle is present. Signed-off-by:
