Simon Horman says: ==================== nfp: flow-independent tc action hardware offload Baowen Zheng says: Allow nfp NIC to offload tc actions independent of flows. The motivation for this work is to offload tc actions independent of flows for nfp NIC. We allow nfp driver to provide hardware offload of OVS metering feature - which calls for policers that may be used by multiple flows and whose lifecycle is independent of any flows that use them. When nfp driver tries to offload a flow table using the independent action, the driver will search if the action is already offloaded to the hardware. If not, the flow table offload will fail. When the nfp NIC successes to offload an action, the user can check in_hw_count when dumping the tc action.

The functions do essentially the same work to verify TCP-MD5 sign. Code can be merged into one family-independent function in order to reduce copy'n'paste and generated code. Later with TCP-AO option added, this will allow to create one function that's responsible for segment verification, that will have all the different checks for MD5/AO/non-signed packets, which in turn will help to see checks for all corner-cases in one function, rather than spread around different families and functions.

Vladimir Oltean says: ==================== FDB entries on DSA LAG interfaces This work permits having static and local FDB entries on LAG interfaces that are offloaded by DSA ports. New API needs to be introduced in drivers. To maintain consistency with the bridging offload code, I've taken the liberty to reorganize the data structures added by Tobias in the DSA core a little bit. Tested on NXP LS1028A (felix switch). Would appreciate feedback/testing on other platforms too. Testing procedure was the one described here: https://patchwork.kernel.org/project/netdevbpf/cover/20210205130240.4072854-1-vladimir.oltean@nxp.com/ with this script: ip link del bond0 ip link add bond0 type bond mode 802.3ad ip link set swp1 down && ip link set swp1 master bond0 && ip link set swp1 up ip link set swp2 down && ip link set swp2 master bond0 && ip link set swp2 up ip link del br0 ip link add br0 type bridge && ip link set br0 up ip link set br0 arp off ip link set bond0 master br0 && ip link set bond0 up ip link set swp0 master br0 && ip link set swp0 up ip link set dev bond0 type bridge_slave flood off learning off bridge fdb add dev bond0 <mac address of other eno0> master static I'm noticing a problem in 'bridge fdb dump' with the 'self' entries, and I didn't solve this. On Ocelot, an entry learned on a LAG is reported as being on the first member port of it (so instead of saying 'self bond0', it says 'self swp1'). This is better than not seeing the entry at all, but when DSA queries for the FDBs on a port via ds->ops->port_fdb_dump, it never queries for FDBs on a LAG. Not clear what we should do there, we aren't in control of the ->ndo_fdb_dump of the bonding/team drivers. Alternatively, we could just consider the 'self' entries reported via ndo_fdb_dump as "better than nothing", and concentrate on the 'master' entries that are in sync with the bridge when packets are flooded to software. ==================== Link: https://lore.kernel.org/r/20220223140054.3379617-1-vladimir.oltean@nxp.comSigned-off-by:

This adds the logic in the Felix DSA driver and Ocelot switch library. For Ocelot switches, the DEST_IDX that is the output of the MAC table lookup is a logical port (equal to physical port, if no LAG is used, or a dynamically allocated number otherwise). The allocation we have in place for LAG IDs is different from DSA's, so we can't use that: - DSA allocates a continuous range of LAG IDs starting from 1 - Ocelot appears to require that physical ports and LAG IDs are in the same space of [0, num_phys_ports), and additionally, ports that aren't in a LAG must have physical port id == logical port id The implication is that an FDB entry towards a LAG might need to be deleted and reinstalled when the LAG ID changes.

This change introduces support for installing static FDB entries towards a bridge port that is a LAG of multiple DSA switch ports, as well as support for filtering towards the CPU local FDB entries emitted for LAG interfaces that are bridge ports. Conceptually, host addresses on LAG ports are identical to what we do for plain bridge ports. Whereas FDB entries _towards_ a LAG can't simply be replicated towards all member ports like we do for multicast, or VLAN. Instead we need new driver API. Hardware usually considers a LAG to be a "logical port", and sets the entire LAG as the forwarding destination. The physical egress port selection within the LAG is made by hashing policy, as usual. To represent the logical port corresponding to the LAG, we pass by value a copy of the dsa_lag structure to all switches in the tree that have at least one port in that LAG. To illustrate why a refcounted list of FDB entries is needed in struct dsa_lag, it is enough to say that: - a LAG may be a bridge port and may therefore receive FDB events even while it isn't yet offloaded by any DSA interface - DSA interfaces may be removed from a LAG while that is a bridge port; we don't want FDB entries lingering around, but we don't want to remove entries that are still in use, either For all the cases below to work, the idea is to always keep an FDB entry on a LAG with a reference count equal to the DSA member ports. So: - if a port joins a LAG, it requests the bridge to replay the FDB, and the FDB entries get created, or their refcount gets bumped by one - if a port leaves a LAG, the FDB replay deletes or decrements refcount by one - if an FDB is installed towards a LAG with ports already present, that entry is created (if it doesn't exist) and its refcount is bumped by the amount of ports already present in the LAG echo "Adding FDB entry to bond with existing ports" ip link del bond0 ip link add bond0 type bond mode 802.3ad ip link set swp1 down && ip link set swp1 master bond0 && ip link set swp1 up ip link set swp2 down && ip link set swp2 master bond0 && ip link set swp2 up ip link del br0 ip link add br0 type bridge ip link set bond0 master br0 bridge fdb add dev bond0 00:01:02:03:04:05 master static ip link del br0 ip link del bond0 echo "Adding FDB entry to empty bond" ip link del bond0 ip link add bond0 type bond mode 802.3ad ip link del br0 ip link add br0 type bridge ip link set bond0 master br0 bridge fdb add dev bond0 00:01:02:03:04:05 master static ip link set swp1 down && ip link set swp1 master bond0 && ip link set swp1 up ip link set swp2 down && ip link set swp2 master bond0 && ip link set swp2 up ip link del br0 ip link del bond0 echo "Adding FDB entry to empty bond, then removing ports one by one" ip link del bond0 ip link add bond0 type bond mode 802.3ad ip link del br0 ip link add br0 type bridge ip link set bond0 master br0 bridge fdb add dev bond0 00:01:02:03:04:05 master static ip link set swp1 down && ip link set swp1 master bond0 && ip link set swp1 up ip link set swp2 down && ip link set swp2 master bond0 && ip link set swp2 up ip link set swp1 nomaster ip link set swp2 nomaster ip link del br0 ip link del bond0 Signed-off-by:

When switchdev_handle_fdb_event_to_device() replicates a FDB event emitted for the bridge or for a LAG port and DSA offloads that, we should notify back to switchdev that the FDB entry on the original device is what was offloaded, not on the DSA slave devices that the event is replicated on.

By construction, the struct net_device *dev passed to dsa_slave_switchdev_event_work() via struct dsa_switchdev_event_work is always a DSA slave device. Therefore, it is redundant to pass struct dsa_switch and int port information in the deferred work structure. This can be retrieved at all times from the provided struct net_device via dsa_slave_to_port(). For the same reason, we can drop the dsa_is_user_port() check in dsa_fdb_offload_notify().

When the switchdev_handle_fdb_event_to_device() event replication helper was created, my original thought was that FDB events on LAG interfaces should most likely be special-cased, not just replicated towards all switchdev ports beneath that LAG. So this replication helper currently does not recurse through switchdev lower interfaces of LAG bridge ports, but rather calls the lag_mod_cb() if that was provided. No switchdev driver uses this helper for FDB events on LAG interfaces yet, so that was an assumption which was yet to be tested. It is certainly usable for that purpose, as my RFC series shows: https://patchwork.kernel.org/project/netdevbpf/cover/20220210125201.2859463-1-vladimir.oltean@nxp.com/ however this approach is slightly convoluted because: - the switchdev driver gets a "dev" that isn't its own net device, but rather the LAG net device. It must call switchdev_lower_dev_find(dev) in order to get a handle of any of its own net devices (the ones that pass check_cb). - in order for FDB entries on LAG ports to be correctly refcounted per the number of switchdev ports beneath that LAG, we haven't escaped the need to iterate through the LAG's lower interfaces. Except that is now the responsibility of the switchdev driver, because the replication helper just stopped half-way. So, even though yes, FDB events on LAG bridge ports must be special-cased, in the end it's simpler to let switchdev_handle_fdb_* just iterate through the LAG port's switchdev lowers, and let the switchdev driver figure out that those physical ports are under a LAG. The switchdev_handle_fdb_event_to_device() helper takes a "foreign_dev_check" callback so it can figure out whether @dev can autonomously forward to @foreign_dev. DSA fills this method properly: if the LAG is offloaded by another port in the same tree as @dev, then it isn't foreign. If it is a software LAG, it is foreign - forwarding happens in software. Whether an interface is foreign or not decides whether the replication helper will go through the LAG's switchdev lowers or not. Since the lan966x doesn't properly fill this out, FDB events on software LAG uppers will get called. By changing lan966x_foreign_dev_check(), we can suppress them. Whereas DSA will now start receiving FDB events for its offloaded LAG uppers, so we need to return -EOPNOTSUPP, since we currently don't do the right thing for them.

The main purpose of this change is to create a data structure for a LAG as seen by DSA. This is similar to what we have for bridging - we pass a copy of this structure by value to ->port_lag_join and ->port_lag_leave. For now we keep the lag_dev, id and a reference count in it. Future patches will add a list of FDB entries for the LAG (these also need to be refcounted to work properly). The LAG structure is created using dsa_port_lag_create() and destroyed using dsa_port_lag_destroy(), just like we have for bridging. Because now, the dsa_lag itself is refcounted, we can simplify dsa_lag_map() and dsa_lag_unmap(). These functions need to keep a LAG in the dst->lags array only as long as at least one port uses it. The refcounting logic inside those functions can be removed now - they are called only when we should perform the operation. dsa_lag_dev() is renamed to dsa_lag_by_id() and now returns the dsa_lag structure instead of the lag_dev net_device. dsa_lag_foreach_port() now takes the dsa_lag structure as argument. dst->lags holds an array of dsa_lag structures. dsa_lag_map() now also saves the dsa_lag->id value, so that linear walking of dst->lags in drivers using dsa_lag_id() is no longer necessary. They can just look at lag.id. dsa_port_lag_id_get() is a helper, similar to dsa_port_bridge_num_get(), which can be used by drivers to get the LAG ID assigned by DSA to a given port. Signed-off-by:

The DSA LAG API will be changed to become more similar with the bridge data structures, where struct dsa_bridge holds an unsigned int num, which is generated by DSA and is one-based. We have a similar thing going with the DSA LAG, except that isn't stored anywhere, it is calculated dynamically by dsa_lag_id() by iterating through dst->lags. The idea of encoding an invalid (or not requested) LAG ID as zero for the purpose of simplifying checks in drivers means that the LAG IDs passed by DSA to drivers need to be one-based too. So back-and-forth conversion is needed when indexing the dst->lags array, as well as in drivers which assume a zero-based index. Signed-off-by:

It is also possible that a port that does not rely on NVMEM has been already created when getting the defer request.

Ipv6 ttl, label and tos fields are modified without first pulling/pushing the ipv6 header, which would have updated the hw csum (if available). This might cause csum validation when sending the packet to the stack, as can be seen in the trace below. Fix this by updating skb->csum if available. Trace resulted by ipv6 ttl dec and then sending packet to conntrack [actions: set(ipv6(hlimit=63)),ct(zone=99)]: [295241.900063] s_pf0vf2: hw csum failure [295241.923191] Call Trace: [295241.925728] <IRQ> [295241.927836] dump_stack+0x5c/0x80 [295241.931240] __skb_checksum_complete+0xac/0xc0 [295241.935778] nf_conntrack_tcp_packet+0x398/0xba0 [nf_conntrack] [295241.953030] nf_conntrack_in+0x498/0x5e0 [nf_conntrack] [295241.958344] __ovs_ct_lookup+0xac/0x860 [openvswitch] [295241.968532] ovs_ct_execute+0x4a7/0x7c0 [openvswitch] [295241.979167] do_execute_actions+0x54a/0xaa0 [openvswitch] [295242.001482] ovs_execute_actions+0x48/0x100 [openvswitch] [295242.006966] ovs_dp_process_packet+0x96/0x1d0 [openvswitch] [295242.012626] ovs_vport_receive+0x6c/0xc0 [openvswitch] [295242.028763] netdev_frame_hook+0xc0/0x180 [openvswitch] [295242.034074] __netif_receive_skb_core+0x2ca/0xcb0 [295242.047498] netif_receive_skb_internal+0x3e/0xc0 [295242.052291] napi_gro_receive+0xba/0xe0 [295242.056231] mlx5e_handle_rx_cqe_mpwrq_rep+0x12b/0x250 [mlx5_core] [295242.062513] mlx5e_poll_rx_cq+0xa0f/0xa30 [mlx5_core] [295242.067669] mlx5e_napi_poll+0xe1/0x6b0 [mlx5_core] [295242.077958] net_rx_action+0x149/0x3b0 [295242.086762] __do_softirq+0xd7/0x2d6 [295242.090427] irq_exit+0xf7/0x100 [295242.093748] do_IRQ+0x7f/0xd0 [295242.096806] common_interrupt+0xf/0xf [295242.100559] </IRQ> [295242.102750] RIP: 0033:0x7f9022e88cbd [295242.125246] RSP: 002b:00007f9022282b20 EFLAGS: 00000246 ORIG_RAX: ffffffffffffffda [295242.132900] RAX: 0000000000000005 RBX: 0000000000000010 RCX: 0000000000000000 [295242.140120] RDX: 00007f9022282ba8 RSI: 00007f9022282a30 RDI: 00007f9014005c30 [295242.147337] RBP: 00007f9014014d60 R08: 0000000000000020 R09: 00007f90254a8340 [295242.154557] R10: 00007f9022282a28 R11: 0000000000000246 R12: 0000000000000000 [295242.161775] R13: 00007f902308c000 R14: 000000000000002b R15: 00007f9022b71f40 Fixes: 3fdbd1ce ("openvswitch: add ipv6 'set' action") Signed-off-by:
