Alejandro Lucero says: ==================== sfc: devlink support for ef100 This patchset adds devlink port support for ef100 allowing setting VFs mac addresses through the VF representor devlink ports. Basic devlink infrastructure is first introduced, then support for info command. Next changes for enumerating MAE ports which will be used for devlink port creation when netdevs are registered. Adding support for devlink port_function_hw_addr_get requires changes in the ef100 driver for getting the mac address based on a client handle. This allows to obtain VFs mac addresses during netdev initialization as well what is included in patch 6. Such client handle is used in patches 7 and 8 for getting and setting devlink port addresses. ==================== Link: https://lore.kernel.org/r/20230215090828.11697-1-alejandro.lucero-palau@amd.comSigned-off-by:

Getting device mac address is currently based on a specific MCDI command only available for the PF. This patch changes the MCDI command to a generic one for PFs and VFs based on a client handle. This allows both PFs and VFs to ask for their mac address during initialization using the CLIENT_HANDLE_SELF. Moreover, the patch allows other client handles which will be used by the PF to ask for mac addresses linked to VFs. This is necessary for suporting the port_function_hw_addr_get devlink function in further patches. Signed-off-by:

Alejandro Lucero authored
Obtaining mport id is based on asking the firmware about it. This is still needed for mport initialization itself, but once the mport data is now kept by the driver, further mport id request can be satisfied internally without firmware interaction. Previous function is just modified in name making clear the firmware interaction. The new function uses the old name and looks for the data in the mport data structure. Signed-off-by:

Pedro Tammela says: ==================== net/sched: transition actions to pcpu stats and rcu Following the work done for act_pedit[0], transition the remaining tc actions to percpu stats and rcu, whenever possible. Percpu stats make updating the action stats very cheap, while combining it with rcu action parameters makes it possible to get rid of the per action lock in the datapath. For act_connmark and act_nat we run the following tests: - tc filter add dev ens2f0 ingress matchall action connmark - tc filter add dev ens2f0 ingress matchall action nat ingress any 10.10.10.10 Our setup consists of a 26 cores Intel CPU and a 25G NIC. We use TRex to shoot 10mpps TCP packets and take perf measurements. Both actions improved performance as expected since the datapath lock disappeared. For act_pedit we move the drop counter to percpu, when available. For act_gate we move the counters to percpu, when available.

The kernel stack can be more consistent by printing the IFF_PROMISC aka promiscuous enable/disable messages with the standard netdev_info message which can include bus and driver info as well as the device. typical command usage from user space looks like: ip link set eth0 promisc <on|off> But lots of utilities such as bridge, tcpdump, etc put the interface into promiscuous mode. old message: [ 406.034418] device eth0 entered promiscuous mode [ 408.424703] device eth0 left promiscuous mode new message: [ 406.034431] ice 0000:17:00.0 eth0: entered promiscuous mode [ 408.424715] ice 0000:17:00.0 eth0: left promiscuous mode Signed-off-by:

When the user sets or clears the IFF_ALLMULTI flag in the netdev, there are no log messages printed to the kernel log to indicate anything happened. This is inexplicably different from most other dev->flags changes, and could suprise the user. Typically this occurs from user-space when a user: ip link set eth0 allmulticast <on|off> However, other devices like bridge set allmulticast as well, and many other flows might trigger entry into allmulticast as well. The new message uses the standard netdev_info print and looks like: [ 413.246110] ixgbe 0000:17:00.0 eth0: entered allmulticast mode [ 415.977184] ixgbe 0000:17:00.0 eth0: left allmulticast mode Signed-off-by:

Jamal Hadi Salim says: ==================== net/sched: Retire some tc qdiscs and classifiers The CBQ + dsmark qdiscs and the tcindex + rsvp classifiers have served us for over 2 decades. Unfortunately, they have not been getting much attention due to reduced usage. While we dont have a good metric for tabulating how much use a specific kernel feature gets, for these specific features we observed that some of the functionality has been broken for some time and no users complained. In addition, syzkaller has been going to town on most of these and finding issues; and while we have been fixing those issues, at times it becomes obvious that we would need to perform bigger surgeries to resolve things found while getting a syzkaller fix in place. After some discussion we feel that in order to reduce the maintenance burden it is best to retire them. This patchset leaves the UAPI alone. I could send another version which deletes the UAPI as well. AFAIK, this has not been done before - so it wasnt clear what how to handle UAPI. It seems legit to just delete it but we would need to coordinate with iproute2 (given they sync up with kernel uapi headers). There are probably other users we don't know of that copy kernel headers. If folks feel differently I will resend the patches deleting UAPI for these qdiscs and classifiers. I will start another thread on iproute2 before sending any patches to iproute2. ==================== Link: https://lore.kernel.org/r/20230214134915.199004-1-jhs@mojatatu.comSigned-off-by:

Steen Hegelund says: ==================== Adding Sparx5 ES0 VCAP support This provides the Egress Stage 0 (ES0) VCAP (Versatile Content-Aware Processor) support for the Sparx5 platform. The ES0 VCAP is an Egress Access Control VCAP that uses frame keyfields and previously classified keyfields to add, rewrite or remove VLAN tags on the egress frames, and is therefore often referred to as the rewriter. The ES0 VCAP also supports trapping frames to the host. The ES0 VCAP has 1 lookup accessible with this chain id: - chain 10000000: ES0 Lookup 0 The ES0 VCAP does not do traffic classification to select a keyset, but it does have two keysets that can be used on all traffic. For now only the ISDX keyset is used. The ES0 VCAP can match on an ISDX key (Ingress Service Index) as one of the frame metadata keyfields, similar to the ES2 VCAP. The ES0 VCAP uses external counters in the XQS (statistics) group. ==================== Link: https://lore.kernel.org/r/20230214104049.1553059-1-steen.hegelund@microchip.comSigned-off-by:

The rule counter must be cleared when creating a new rule, even if the VCAP lookup is currently disabled. This ensures that rules located in VCAPs that use external counters (such as Sparx5 IS2 and ES0) will have their counter reset even if the VCAP lookup is not enabled at the moment. Signed-off-by:
