Vladimir Oltean says: ==================== xstats for tc-taprio As a result of this discussion: https://lore.kernel.org/intel-wired-lan/20230411055543.24177-1-muhammad.husaini.zulkifli@intel.com/ it became apparent that tc-taprio should make an effort to standardize statistics counters related to the 802.1Qbv scheduling as implemented by the NIC. I'm presenting here one counter suggested by the standard, and one counter defined by the NXP ENETC controller from LS1028A. Both counters are reported globally and per traffic class - drivers get different callbacks for reporting both of these, and get to choose what to report in both cases. The iproute2 counterpart is available here for testing: https://github.com/vladimiroltean/iproute2/commits/taprio-xstats ==================== Signed-off-by:

Offloading drivers may report some additional statistics counters, some of them even suggested by 802.1Q, like TransmissionOverrun. In my opinion we don't have to limit ourselves to reporting counters only globally to the Qdisc/interface, especially if the device has more detailed reporting (per traffic class), since the more detailed info is valuable for debugging and can help identifying who is exceeding its time slot. But on the other hand, some devices may not be able to report both per TC and global stats. So we end up reporting both ways, and use the good old ethtool_put_stat() strategy to determine which statistics are supported by this NIC. Statistics which aren't set are simply not reported to netlink. For this reason, we need something dynamic (a nlattr nest) to be reported through TCA_STATS_APP, and not something daft like the fixed-size and inextensible struct tc_codel_xstats. A good model for xstats which are a nlattr nest rather than a fixed struct seems to be cake. # Global stats $ tc -s qdisc show dev eth0 root # Per-tc stats $ tc -s class show dev eth0 Signed-off-by:

Inspired from struct flow_cls_offload :: cmd, in order for taprio to be able to report statistics (which is future work), it seems that we need to drill one step further with the ndo_setup_tc(TC_SETUP_QDISC_TAPRIO) multiplexing, and pass the command as part of the common portion of the muxed structure. Since we already have an "enable" variable in tc_taprio_qopt_offload, refactor all drivers to check for "cmd" instead of "enable", and reject every other command except "replace" and "destroy" - to be future proof.

In taprio_dump_class_stats() we don't need a reference to the root Qdisc once we get the reference to the child corresponding to this traffic class, so it's okay to overwrite "sch". But in a future patch we will need the root Qdisc too, so create a dedicated "child" pointer variable to hold the child reference. This also makes the code adhere to a more conventional coding style.

Christian Marangi says: ==================== leds: introduce new LED hw control APIs Since this series is cross subsystem between LED and netdev, a stable branch was created to facilitate merging process. This is based on top of branch ib-leds-netdev-v6.5 present here [1] and rebased on top of net-next since the LED stable branch got merged. This is a continue of [2]. It was decided to take a more gradual approach to implement LEDs support for switch and phy starting with basic support and then implementing the hw control part when we have all the prereq done. This is the main part of the series, the one that actually implement the hw control API. Some history about this feature and why ======================================= This proposal is highly requested by the entire net community but the API is not strictly designed for net usage but for a more generic usage. Initial version were very flexible and designed to try to support every aspect of the LED driver with many complex function that served multiple purpose. There was an idea to have sw only and hw only LEDs and sw only and hw only LEDs. With some heads up from Andrew from the net mailing list, it was suggested to implement a more basic yet easy to implement system. These API strictly work with a designated trigger to offload their function. This may be confused with hw blink offload but LED may have an even more advanced configuration where the entire aspect of the trigger is offloaded and completely handled by the hardware. An example of this usage are PHY or switch port LEDs. Almost every of these kind of device have multiple LED attached and provide info of the current port state. Currently we lack any support of them but these device always provide a way to configure them, from basic feature like turning the LED off or no (implemented in previous series related to this feature) or even entirely driven by the hw and power on/off/blink based on some events, like tx/rx traffic, ethernet cable attached, link speed of 10mbps, 100mbps, 1000mbps or more. They can also support multiple logic like blink with traffic only if a particular link speed is attached. (an example of this is when a LED is designated to be turned on only with 100mbps link speed and configured to blink on traffic and a secondary LED of a different color is present to serve the same function but only when the link speed is 1000mbps) These case are very common for a PHY or a switch but they were never standardized so OEM support all kind of variant and configuration. Again with Andrew we compared some feature and we reached a common set of modes that are for sure present in every kind of devices. And this concludes history and why. What is present in this series ============================== This patch contain the required API to support this feature, I decided on the name of hw control to quickly describe this feature. I documented each require API in the related Documentation for leds-class so I think it might me redundant to expose them here. Feel free to tell me how to improve it if anything is not clear. On an abstract idea, this feature require this: - The trigger needs to make use of it, this is currently implemented for the netdev trigger but other trigger can be expanded if the device expose these function. An idea might be a anything that handle a storage disk and have the LED configurable to blink when there is any activity to the disk. - The LED driver needs to expose and implement these new API. Currently a LED driver supports only a trigger. The trigger should use the related helper to check if the LED can be driven hy hardware. The different modes a trigger support are exposed in the kernel include leds.h header and are used by the LED driver to understand what to do. From a user standpoint, he should enable modes as usual from sysfs and if anything is not supported warned. Final words and missing piece from this series ============================================== I honestly hope this feature can finally be implemented. This series originally had also additional modes and logic to add to the netdev trigger, but I decided to strip them and implement only the API and support basic tx and rx. After this is merged, I will quickly propose these additional modes. Currently this is limited to tx and rx and this is what the current user qca8k use. Marvell PHY support link and a generic blink with any kind of traffic (both rx and tx). qca8k switch supports keeping the LED on based on link speed. The next series will add the concept of hw control only modes to the netdev trigger and support for these additional modes: - link_10 - link_100 - link_1000 - activity The current implementation is voluntary basic and limited to put the ground work and have something easy to implement and usable. 99% part of the logic is done on the trigger side, leaving to the LED driver only the validating and the apply part. As shown for the PHY led binding, people are really intrested in this feature as quickly after they were merged, people were already working on adding support for it.

Add support for LED hw control for the netdev trigger. The trigger on calling set_baseline_state to configure a new mode, will do various check to verify if hw control can be used for the requested mode in can_hw_control() function. It will first check if the LED driver supports hw control for the netdev trigger, then will use hw_control_is_supported() and finally will call hw_control_set() to apply the requested mode. To use such mode, interval MUST be set to the default value and net_dev MUST be set. If one of these 2 value are not valid, hw control will never be used and normal software fallback is used. The default interval value is moved to a define to make sure they are always synced. Signed-off-by:

Some specific LED triggers blink the LED based on events from a device or subsystem. For example, an LED could be blinked to indicate a network device is receiving packets, or a disk is reading blocks.

Since commit a4dfa72d ("tipc: set default MTU for UDP media"), it's been no longer using dev->mtu for b->mtu, and the issue described in commit 3de81b75 ("tipc: check minimum bearer MTU") doesn't exist in UDP bearer any more. Besides, dev->mtu can still be changed to a too small mtu after the UDP bearer is created even with tipc_mtu_bad() check in tipc_udp_enable(). Note that NETDEV_CHANGEMTU event processing in tipc_l2_device_event() doesn't really work for UDP bearer. So this patch deletes the unnecessary tipc_mtu_bad from tipc_udp_enable. Signed-off-by:

MV88E6361 is a 8 ports switch with 5 integrated Gigabit PHYs and 3 2.5Gigabit SerDes interfaces.

Ido Schimmel says: ==================== Add layer 2 miss indication and filtering tl;dr ===== This patchset adds a single bit to the tc skb extension to indicate that a packet encountered a layer 2 miss in the bridge and extends flower to match on this metadata. This is required for non-DF (Designated Forwarder) filtering in EVPN multi-homing which prevents decapsulated BUM packets from being forwarded multiple times to the same multi-homed host. Background ========== In a typical EVPN multi-homing setup each host is multi-homed using a set of links called ES (Ethernet Segment, i.e., LAG) to multiple leaf switches in a rack. These switches act as VTEPs and are not directly connected (as opposed to MLAG), but can communicate with each other (as well as with VTEPs in remote racks) via spine switches over L3. When a host sends a BUM packet over ES1 to VTEP1, the VTEP will flood it to other VTEPs in the network, including those connected to the host over ES1. The receiving VTEPs must drop the packet and not forward it back to the host. This is called "split-horizon filtering" (SPH) [1]. FRR configures SPH filtering using two tc filters. The first, an ingress filter that matches on packets received from VTEP1 and marks them using a fwmark (firewall mark). The second, an egress filter configured on the LAG interface connected to the host that matches on the fwmark and drops the packets. Example: # tc filter add dev vxlan0 ingress pref 1 proto all flower enc_src_ip $VTEP1_IP action skbedit mark 101 # tc filter add dev bond0 egress pref 1 handle 101 fw action drop Motivation ========== For each ES, only one VTEP is elected by the control plane as the DF. The DF is responsible for forwarding decapsulated BUM traffic to the host over the ES. The non-DF VTEPs must drop such traffic as otherwise the host will receive multiple copies of BUM traffic. This is called "non-DF filtering" [2]. Filtering of multicast and broadcast traffic can be achieved using the following flower filter: # tc filter add dev bond0 egress pref 1 proto all flower indev vxlan0 dst_mac 01:00:00:00:00:00/01:00:00:00:00:00 action drop Unlike broadcast and multicast traffic, it is not currently possible to filter unknown unicast traffic. The classification into unknown unicast is performed by the bridge driver, but is not visible to other layers. Implementation ============== The proposed solution is to add a single bit to the tc skb extension that is set by the bridge for packets that encountered an FDB or MDB miss. The flower classifier is extended to be able to match on this new metadata bit in a similar fashion to existing metadata options such as 'indev'. A bit that is set for every flooded packet would also work, but it does not allow us to differentiate between registered and unregistered multicast traffic which might be useful in the future. A relatively generic name is chosen for this bit - 'l2_miss' - to allow its use to be extended to other layer 2 devices such as VXLAN, should a use case arise. With the above, the control plane can implement a non-DF filter using the following tc filters: # tc filter add dev bond0 egress pref 1 proto all flower indev vxlan0 dst_mac 01:00:00:00:00:00/01:00:00:00:00:00 action drop # tc filter add dev bond0 egress pref 2 proto all flower indev vxlan0 l2_miss true action drop The first drops broadcast and multicast traffic and the second drops unknown unicast traffic. Testing ======= A test exercising the different permutations of the 'l2_miss' bit is added in patch #8. Patchset overview ================= Patch #1 adds the new bit to the tc skb extension and sets it in the bridge driver for packets that encountered a miss. The marking of the packets and the use of this extension is protected by the 'tc_skb_ext_tc' static key in order to keep performance impact to a minimum when the feature is not in use. Patch #2 extends the flow dissector to dissect this information from the tc skb extension into the 'FLOW_DISSECTOR_KEY_META' key. Patch #3 extends the flower classifier to be able to match on the new layer 2 miss metadata. The classifier enables the 'tc_skb_ext_tc' static key upon the installation of the first filter that matches on 'l2_miss' and disables the key upon the removal of the last filter that matches on it. Patch #4 rejects matching on the new metadata in drivers that already support the 'FLOW_DISSECTOR_KEY_META' key. Patches #5-#6 are small preparations in mlxsw. Patch #7 extends mlxsw to be able to match on layer 2 miss. Patch #8 adds a selftest. iproute2 patches can be found here [3].
