661dc19066 arm64 fix/update:
- 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

Merge tag 'net-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "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"

0e875ee5e8 remoteproc updates for v6.9
Qualcomm SM8650 audio, compute and modem remoteproc are added. Qualcomm
 X1 Elite audio and compute remoteprocs are added, after support for
 shutting down the bootloader-loaded firmware loaded into the audio DSP..
 
 A dozen drivers in the subsystem are transitioned to use devres helpers
 for remoteproc and memory allocations.
 
 It makes it possible to acquire in-kernel handle to individual
 remoteproc instances in a cluster.
 
 The release of DMA memory for remoteproc virtio is corrected to ensure
 that restarting due to a watchdog bite doesn't attempt to allocate the
 memory again without first freeing it.
 
 Last, but not least, a couple of DeviceTree binding cleanups.

====================
Netfilter fixes for net

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,
   from Quan Tian.

e4137851d4 selftests: forwarding: Fix ping failure due to short timeout
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.

69ddba9d17 net: dsa: mt7530: fix handling of all link-local frames
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.

e8bf353577 net: dsa: mt7530: fix link-local frames that ingress vlan filtering ports
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.

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
d28139c4e9 ("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.

 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.

1a77557d48 rcu: add a helper to report consolidated flavor QS
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.
