      Pull arm64 fixes from Catalin Marinas:
      
       - Re-instate the CPUMASK_OFFSTACK option for arm64 when NR_CPUS > 256.
         The bug that led to the initial revert was the cpufreq-dt code not
         using zalloc_cpumask_var().
      
       - Make the STARFIVE_STARLINK_PMU config option depend on 64BIT to
         prevent compile-test failures on 32-bit architectures due to missing
         writeq().

       "Including fixes from CAN, netfilter, wireguard and IPsec.
      
        I'd like to highlight [ lowlight? - Linus ] Florian W stepping down as
        a netfilter maintainer due to constant stream of bug reports. Not sure
        what we can do but IIUC this is not the first such case.
      
        Current release - regressions:
      
         - rxrpc: fix use of page_frag_alloc_align(), it changed semantics and
           we added a new caller in a different subtree
      
         - xfrm: allow UDP encapsulation only in offload modes
      
        Current release - new code bugs:
      
         - tcp: fix refcnt handling in __inet_hash_connect()
      
         - Revert "net: Re-use and set mono_delivery_time bit for userspace
           tstamp packets", conflicted with some expectations in BPF uAPI
      
        Previous releases - regressions:
      
         - ipv4: raw: fix sending packets from raw sockets via IPsec tunnels
      
         - devlink: fix devlink's parallel command processing
      
         - veth: do not manipulate GRO when using XDP
      
         - esp: fix bad handling of pages from page_pool
      
        Previous releases - always broken:
      
         - report RCU QS for busy network kthreads (with Paul McK's blessing)
      
         - tcp/rds: fix use-after-free on netns with kernel TCP reqsk
      
         - virt: vmxnet3: fix missing reserved tailroom with XDP
      
        Misc:
      
         - couple of build fixes for Documentation"

      The following patchset contains Netfilter fixes for net. There is a
      larger batch of fixes still pending that will follow up asap, this is
      what I deemed to be more urgent at this time:
      
      1) Use clone view in pipapo set backend to release elements from destroy
         path, otherwise it is possible to destroy elements twice.
      
      2) Incorrect check for internal table flags lead to bogus transaction
         objects.
      
      3) Fix counters memleak in netdev basechain update error path,

      selftests: forwarding: Fix ping failure due to short timeout · e4137851
      Ido Schimmel authored
      The tests send 100 pings in 0.1 second intervals and force a timeout of
      11 seconds, which is borderline (especially on debug kernels), resulting
      in random failures in netdev CI [1].
      
      Fix by increasing the timeout to 20 seconds. It should not prolong the
      test unless something is wrong, in which case the test will rightfully
      fail.

      If nft_netdev_register_hooks() fails, the memory associated with

      net: dsa: mt7530: fix handling of all link-local frames · 69ddba9d
      Arınç ÜNAL authored
      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.

      net: dsa: mt7530: fix link-local frames that ingress vlan filtering ports · e8bf3535
      Arınç ÜNAL authored
      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.

      ====================
      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
      d28139c4 ("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.

      net: report RCU QS on threaded NAPI repolling · d6dbbb11
      Yan Zhai authored
      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.

      rcu: add a helper to report consolidated flavor QS · 1a77557d
      Yan Zhai authored
      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.

           makefiles like perf does, inheriting its benefits. For example,
           having a proper way to handle library dependencies.
      
         - The timerlat tracer has an interface for any tool to use. rtla
           timerlat tool uses this interface dispatching its own threads as
           workload. But, rtla timerlat could also be used for any other
           process. So, add 'rtla timerlat -U' option, allowing the timerlat
           tool to measure the latency of any task using the timerlat tracer
           interface.

         - Update makefiles for verification/rv, using tools/build/ makefiles
