2024-03-21net: dsa: mt7530: fix handling of all link-local framesArınç ÜNAL2-4/+46
Currently, the MT753X switches treat frames with :01-0D and :0F MAC DAs as regular multicast frames, therefore flooding them to user ports. On page 205, section "8.6.3 Frame filtering" of the active standard, IEEE Std 802.1Q™-2022, it is stated that frames with 01:80:C2:00:00:00-0F as MAC DA must only be propagated to C-VLAN and MAC Bridge components. That means VLAN-aware and VLAN-unaware bridges. On the switch designs with CPU ports, these frames are supposed to be processed by the CPU (software). So we make the switch only forward them to the CPU port. And if received from a CPU port, forward to a single port. The software is responsible of making the switch conform to the latter by setting a single port as destination port on the special tag. This switch intellectual property cannot conform to this part of the standard fully. Whilst the REV_UN frame tag covers the remaining :04-0D and :0F MAC DAs, it also includes :22-FF which the scope of propagation is not supposed to be restricted for these MAC DAs. Set frames with :01-03 MAC DAs to be trapped to the CPU port(s). Add a comment for the remaining MAC DAs. Note that the ingress port must have a PVID assigned to it for the switch to forward untagged frames. A PVID is set by default on VLAN-aware and VLAN-unaware ports. However, when the network interface that pertains to the ingress port is attached to a vlan_filtering enabled bridge, the user can remove the PVID assignment from it which would prevent the link-local frames from being trapped to the CPU port. I am yet to see a way to forward link-local frames while preventing other untagged frames from being forwarded too.

2024-03-21net: dsa: mt7530: fix link-local frames that ingress vlan filtering portsArınç ÜNAL2-9/+23
Whether VLAN-aware or not, on every VID VLAN table entry that has the CPU port as a member of it, frames are set to egress the CPU port with the VLAN tag stacked. This is so that VLAN tags can be appended after hardware special tag (called DSA tag in the context of Linux drivers). For user ports on a VLAN-unaware bridge, frame ingressing the user port egresses CPU port with only the special tag. For user ports on a VLAN-aware bridge, frame ingressing the user port egresses CPU port with the special tag and the VLAN tag. This causes issues with link-local frames, specifically BPDUs, because the software expects to receive them VLAN-untagged. There are two options to make link-local frames egress untagged. Setting CONSISTENT or UNTAGGED on the EG_TAG bits on the relevant register. CONSISTENT means frames egress exactly as they ingress. That means egressing with the VLAN tag they had at ingress or egressing untagged if they ingressed untagged. Although link-local frames are not supposed to be transmitted VLAN-tagged, if they are done so, when egressing through a CPU port, the special tag field will be broken.

To prevent confusing the software, force the frame to egress UNTAGGED instead of CONSISTENT. This way, frames can't possibly be received TAGGED by software which would have the special tag field broken. VLAN Tag Egress Procedure For all frames, one of these options set the earliest in this order will apply to the frame: - EG_TAG in certain registers for certain frames. This will apply to frame with matching MAC DA or EtherType. - EG_TAG in the address table. This will apply to frame at its incoming port. - EG_TAG in the PVC register. This will apply to frame at its incoming port. - EG_CON and [EG_TAG per port] in the VLAN table. This will apply to frame at its outgoing port. - EG_TAG in the PCR register. This will apply to frame at its outgoing port. EG_TAG in certain registers for certain frames: PPPoE Discovery_ARP/RARP: PPP_EG_TAG and ARP_EG_TAG in the APC register. IGMP_MLD: IGMP_EG_TAG and MLD_EG_TAG in the IMC register. BPDU and PAE: BPDU_EG_TAG and PAE_EG_TAG in the BPC register. REV_01 and REV_02: R01_EG_TAG and R02_EG_TAG in the RGAC1 register. REV_03 and REV_0E: R03_EG_TAG and R0E_EG_TAG in the RGAC2 register. REV_10 and REV_20: R10_EG_TAG and R20_EG_TAG in the RGAC3 register. REV_21 and REV_UN: R21_EG_TAG and RUN_EG_TAG in the RGAC4 register. With this change, it can be observed that a bridge interface with stp_state and vlan_filtering enabled will properly block ports now.

2024-03-21Merge branch 'report-rcu-qs-for-busy-network-kthreads'Jakub Kicinski3-0/+37
Yan Zhai says: ==================== Report RCU QS for busy network kthreads This changeset fixes a common problem for busy networking kthreads. These threads, e.g. NAPI threads, typically will do: * polling a batch of packets * if there are more work, call cond_resched() to allow scheduling * continue to poll more packets when rx queue is not empty We observed this being a problem in production, since it can block RCU tasks from making progress under heavy load. Investigation indicates that just calling cond_resched() is insufficient for RCU tasks to reach quiescent states. This also has the side effect of frequently clearing the TIF_NEED_RESCHED flag on voluntary preempt kernels. As a result, schedule() will not be called in these circumstances, despite schedule() in fact provides required quiescent states. This at least affects NAPI threads, napi_busy_loop, and also cpumap kthread. By reporting RCU QSes in these kthreads periodically before cond_resched, the blocked RCU waiters can correctly progress. Instead of just reporting QS for RCU tasks, these code share the same concern as noted in the commit d28139c4e967 ("rcu: Apply RCU-bh QSes to RCU-sched and RCU-preempt when safe"). So report a consolidated QS for safety. It is worth noting that, although this problem is reproducible in napi_busy_loop, it only shows up when setting the polling interval to as high as 2ms, which is far larger than recommended 50us-100us in the documentation. So napi_busy_loop is left untouched. Lastly, this does not affect RT kernels, which does not enter the scheduler through cond_resched(). Without the mentioned side effect, schedule() will be called time by time, and clear the RCU task holdouts.

2024-03-21bpf: report RCU QS in cpumap kthreadYan Zhai1-0/+3
When there are heavy load, cpumap kernel threads can be busy polling packets from redirect queues and block out RCU tasks from reaching quiescent states. It is insufficient to just call cond_resched() in such context. Periodically raise a consolidated RCU QS before cond_resched fixes the problem.

2024-03-21net: report RCU QS on threaded NAPI repollingYan Zhai1-0/+3
NAPI threads can keep polling packets under load. Currently it is only calling cond_resched() before repolling, but it is not sufficient to clear out the holdout of RCU tasks, which prevent BPF tracing programs from detaching for long period. This can be reproduced easily with following set up: ip netns add test1 ip netns add test2 ip -n test1 link add veth1 type veth peer name veth2 netns test2 ip -n test1 link set veth1 up ip -n test1 link set lo up ip -n test2 link set veth2 up ip -n test2 link set lo up ip -n test1 addr add 192.168.1.2/31 dev veth1 ip -n test1 addr add 1.1.1.1/32 dev lo ip -n test2 addr add 192.168.1.3/31 dev veth2 ip -n test2 addr add 2.2.2.2/31 dev lo ip -n test1 route add default via 192.168.1.3 ip -n test2 route add default via 192.168.1.2 for i in `seq 10 210`; do for j in `seq 10 210`; do ip netns exec test2 iptables -I INPUT -s 3.3.$i.$j -p udp --dport 5201 done done ip netns exec test2 ethtool -K veth2 gro on ip netns exec test2 bash -c 'echo 1 > /sys/class/net/veth2/threaded' ip netns exec test1 ethtool -K veth1 tso off Then run an iperf3 client/server and a bpftrace script can trigger it: ip netns exec test2 iperf3 -s -B 2.2.2.2 >/dev/null& ip netns exec test1 iperf3 -c 2.2.2.2 -B 1.1.1.1 -u -l 1500 -b 3g -t 100 >/dev/null& bpftrace -e 'kfunc:__napi_poll{@=count();} interval:s:1{exit();}' Report RCU quiescent states periodically will resolve the issue.

2024-03-21rcu: add a helper to report consolidated flavor QSYan Zhai1-0/+31
When under heavy load, network processing can run CPU-bound for many tens of seconds. Even in preemptible kernels (non-RT kernel), this can block RCU Tasks grace periods, which can cause trace-event removal to take more than a minute, which is unacceptably long. This commit therefore creates a new helper function that passes through both RCU and RCU-Tasks quiescent states every 100 milliseconds. This hard-coded value suffices for current workloads.
