arm64: dts: allwinner: h5: Add Libre Computer ALL-H5-CC H5 board
The Libre Computer ALL-H5-CC board is an upgraded version of the
ALL-H3-CC. Changes include:

  - Gigabit Ethernet via external RTL8211E Ethernet PHY
  - 16 MiB SPI NOR flash memory
  - PoE tap header
  - Line out jack removed

Only H5 variant test samples were made available, and the vendor is not
certain whether other SoC variants would be made or not. Furthermore the
board is a minor upgrade compared to the ALL-H3-CC. Thus the device tree
simply includes the one for the ALL-H3-CC, and adds the changes on top.

ARM: dts: sun8i: R40: Add SPI controllers nodes and pinmuxes
The Allwinner R40 SoC contains four SPI controllers, using the newer
sun6i design (but at the legacy addresses).
The controller seems to be fully compatible to the A64 one, so no driver
changes are necessary.
The first three controllers can be used on two sets of pins, but SPI3 is
only routed to one set on Port A.
Only the pin groups for SPI0 on PortC and SPI1 on PortI are added here,
because those seem to be the only one exposed on the Bananapi boards.

Tested by connecting a SPI flash to a Bananapi M2 Berry SPI0 and SPI1
header pins.

After further debugging, turns out while in case of other helper functions
we disallow passing modified ctx, the special case of ld/abs/ind instruction
which has similar semantics (except r6 being the ctx argument) is missing
such check. Modified ctx is impossible here as bpf_skb_load_helper_8_no_cache()
and others are expecting skb fields in original position, hence, add
check_ctx_reg() to reject any modified ctx. Issue was first introduced back
in f1174f77b5 ("bpf/verifier: rework value tracking").

81b055205e igc: Add support for RX timestamping
This adds support for timestamping received packets.

It is based on the i210, as many features of i225 work the same way.
The main difference from i210 is that i225 has support for choosing
the timer register to use when timestamping packets. Right now, we
only support using timer 0. The other difference is that i225 stores
two timestamps in the receive descriptor, right now, we only retrieve
one.

e10360f815 bpf: cgroup: prevent out-of-order release of cgroup bpf
Before commit 4bfc0bb2c6 ("bpf: decouple the lifetime of cgroup_bpf from cgroup itself")
cgroup bpf structures were released with
corresponding cgroup structures. It guaranteed the hierarchical order
of destruction: children were always first. It preserved attached
programs from being released before their propagated copies.

But with cgroup auto-detachment there are no such guarantees anymore:
cgroup bpf is released as soon as the cgroup is offline and there are
no live associated sockets. It means that an attached program can be
detached and released, while its propagated copy is still living
in the cgroup subtree. This will obviously lead to an use-after-free
bug.

To reproduce the issue the following script can be used:

  #!/bin/bash

  CGROOT=/sys/fs/cgroup

  mkdir -p ${CGROOT}/A ${CGROOT}/B ${CGROOT}/A/C
  sleep 1

  ./test_cgrp2_attach ${CGROOT}/A egress &
  A_PID=$!
  ./test_cgrp2_attach ${CGROOT}/B egress &
  B_PID=$!

  echo $$ > ${CGROOT}/A/C/cgroup.procs
  iperf -s &
  S_PID=$!
  iperf -c localhost -t 100 &
  C_PID=$!

  sleep 1

  echo $$ > ${CGROOT}/B/cgroup.procs
  echo ${S_PID} > ${CGROOT}/B/cgroup.procs
  echo ${C_PID} > ${CGROOT}/B/cgroup.procs

  sleep 1

  rmdir ${CGROOT}/A/C
  rmdir ${CGROOT}/A

  sleep 1

  kill -9 ${S_PID} ${C_PID} ${A_PID} ${B_PID}

On the unpatched kernel the following stacktrace can be obtained:

Fix this by grabbing a reference to the bpf structure of each ancestor
on the initialization of the cgroup bpf structure, and dropping the
reference at the end of releasing the cgroup bpf structure.

This will restore the hierarchical order of cgroup bpf releasing,
without adding any operations on hot paths.

Thanks to Josef Bacik for the debugging and the initial analysis of
the problem.

50d31037e4 Merge branch 'ethtool-allow-nesting-of-begin-and-complete-callbacks'
Michal Kubecek says:

====================
ethtool: allow nesting of begin() and complete() callbacks

The ethtool ioctl interface used to guarantee that ethtool_ops callbacks
were always called in a block between calls to ->begin() and ->complete()
(if these are defined) and that this whole block was executed with RTNL
lock held:

	rtnl_lock();
	ops->begin();
	/* other ethtool_ops calls */
	ops->complete();
	rtnl_unlock();

This prevented any nesting or crossing of the begin-complete blocks.
However, this is no longer guaranteed even for ioctl interface as at least
ethtool_phys_id() releases RTNL lock while waiting for a timer. With the
introduction of netlink ethtool interface, the begin-complete pairs are
naturally nested e.g. when a request triggers a netlink notification.

Fortunately, only minority of networking drivers implements begin() and
complete() callbacks and most of those that do, fall into three groups:

  - wrappers for pm_runtime_get_sync() and pm_runtime_put()
  - wrappers for clk_prepare_enable() and clk_disable_unprepare()
  - begin() checks netif_running() (fails if false), no complete()

First two have their own refcounting, third is safe w.r.t. nesting of the
blocks.

Only three in-tree networking drivers need an update to deal with nesting
of begin() and complete() calls: via-velocity and epic100 perform resume
and suspend on their own and wil6210 completely serializes the calls using
its own mutex (which would lead to a deadlock if a request request
triggered a netlink notification). The series addresses these problems.

changes between v1 and v2:

    Lunn)

4ac0ac847f epic100: allow nesting of ethtool_ops begin() and complete()
Unlike most networking drivers using begin() and complete() ethtool_ops
callbacks to resume a device which is down and suspend it again when done,
epic100 does not use standard refcounted infrastructure but sets device
sleep state directly.

With the introduction of netlink ethtool interface, we may have nested
begin-complete blocks so that inner complete() would put the device back to
sleep for the rest of the outer block.

To avoid rewriting an old and not very actively developed driver, just add
a nesting counter and only perform resume and suspend on the outermost
level.

a69faa0910 wil6210: get rid of begin() and complete() ethtool_ops
The wil6210 driver locks a mutex in begin() ethtool_ops callback and
unlocks it in complete() so that all ethtool requests are serialized. This
is not going to work correctly with netlink interface; e.g. when ioctl
triggers a netlink notification, netlink code would call begin() again
while the mutex taken by ioctl code is still held by the same task.

Let's get rid of the begin() and complete() callbacks and move the mutex
locking into the remaining ethtool_ops handlers except get_drvinfo which
only copies strings that are not changing so that there is no need for
serialization.

17aa23ee72 fcnal-test: Fix vrf argument in local tcp tests
The recent MD5 tests added duplicate configuration in the default VRF.
This change exposed a bug in existing tests designed to verify no
connection when client and server are not in the same domain. The
server should be running bound to the vrf device with the client run
in the default VRF (the -2 option is meant for validating connection
data). Fix the option for both tests.

While technically this is a bug in previous releases, the tests are
properly failing since the default VRF does not have any routing
configuration so there really is no need to backport to prior releases.

The hardware pipeline contains some checks that, by default, are
configured to drop packets. Since the software data path does not drop
packets due to these reasons and since we are interested in offloading
the software data path to hardware, then these checks should be disabled
in the hardware pipeline as well.

This patch set changes mlxsw to disable four of these checks and adds
corresponding selftests. The tests pass both when the software data path
is exercised (using veth pair) and when the hardware data path is
exercised (using mlxsw ports in loopback).

The 6390 family uses an extended register to set the port connected to
the CPU. The lower 5 bits indicate the port, the upper three bits are
the priority of the frames as they pass through the switch, what
egress queue they should use, etc. Since frames being set to the CPU
are typically management frames, BPDU, IGMP, ARP, etc set the priority
to 7, the reset default, and the highest.

This patch is to fix a memleak caused by no place to free cmd->obj.chunk
for the unprocessed SCTP_CMD_REPLY. This issue occurs when failing to
process a cmd while there're still SCTP_CMD_REPLY cmds on the cmd seq
with an allocated chunk in cmd->obj.chunk.

So fix it by freeing cmd->obj.chunk for each SCTP_CMD_REPLY cmd left on
the cmd seq when any cmd returns error. While at it, also remove 'nomem'
label.

7061867b59 net: hns3: replace an unsuitable variable type in hclge_inform_reset_assert_to_vf()
In hclge_inform_reset_assert_to_vf(), variable reset_type(enum type)
will be copied into msg_data whose size is 2 bytes. Currently, hip08
is a little-endian machine, so the lower two bytes of reset_type will
be copied to msg_data. But when running on a big-endian machine,
msg_data will have a wrong value(the higher two bytes of reset_type).

So this patch modifies the type of reset_type to u16, and adds a
build check in case enum hnae3_reset_type has value larger than
U16_MAX.

This patch modifies the misc IRQ names as "hclge/hclgevf"-misc-
"pci name". And now the IRQ name is not related to net device

that is enough.

5bffde62a1 net: hns3: modify the IRQ name of TQP vector
When rename the net devices, the IRQ number can not be
fetched by the net device name, because the driver request
the IRQ resources only when the vector resource changed, and
the rename operation did not change the vector resources,
so the IRQ name keeps the previous net device name.

ASoC: Intel: sof_rt5682: Ignore the speaker amp when there isn't one.
Some members of the Google_Hatch family include a rt5682 jack codec, but
no speaker amplifier. This uses the same driver (sof_rt5682) as a
combination of rt5682 jack codec and max98357a speaker amplifier. Within
the sof_rt5682 driver, these cases are not currently distinguishable,
relying on a DMI quirk to decide the configuration. This causes an
incorrect configuration when only the rt5682 is present on a
Google_Hatch device.

For CML, the jack codec is used as the primary key when matching,
with a possible speaker amplifier described in quirk_data. The two cases
of interest are the second and third 10EC5682 entries in
snd_soc_acpi_intel_cml_machines[]. The second entry matches the
combination of rt5682 and max98357a, resulting in the quirk_data field
in the snd_soc_acpi_mach being non-null, pointing at
max98357a_spk_codecs, the snd_soc_acpi_codecs for the matched speaker
amplifier. The third entry matches just the rt5682, resulting in a null
quirk_data.

The sof_rt5682 driver's DMI data matching identifies that a speaker
amplifier is present for all Google_Hatch family devices. Detect cases
where there is no speaker amplifier by checking for a null quirk_data in
the snd_soc_acpi_mach and remove the speaker amplifier bit in that case.

ASoC: Intel: bytcht_es8316: Fix Irbis NB41 netbook quirk
When a quirk for the Irbis NB41 netbook was added, to override the defaults
for this device, I forgot to add/keep the BYT_CHT_ES8316_SSP0 part of the
defaults, completely breaking audio on this netbook.

This commit adds the BYT_CHT_ES8316_SSP0 flag to the Irbis NB41 netbook
quirk, making audio work again.

ec7b3f5372 spi: Fixes for v5.5
A small collection of fixes here, one to make the newly added PTP
 timestamping code more accurate, a few driver fixes and a fix for the
 core DT binding to document the fact that we support eight wire buses.

5f70bde26a selftests: fix build behaviour on targets' failures
Currently, when some of the KSFT subsystems fails to build, the toplevel
KSFT Makefile just keeps carrying on with the build process.

This behaviour is expected and desirable especially in the context of a CI
system running KSelfTest, since it is not always easy to guarantee that the
most recent and esoteric dependencies are respected across all KSFT TARGETS
in a timely manner.

Unfortunately, as of now, this holds true only if the very last of the
built subsystems could have been successfully compiled: if the last of
those subsystem instead failed to build, such failure is taken as the whole
outcome of the Makefile target and the complete build/install process halts
even though many other preceding subsytems were in fact already built
successfully.

Fix the KSFT Makefile behaviour related to all/install targets in order
to fail as a whole only when the all/install targets have failed for all
of the requested TARGETS, while succeeding when at least one of TARGETS
has been successfully built.
