Notice that device_suspend_noirq(), device_suspend_late() and
device_suspend() all set async_error on errors, so they don't really
need to return a value. Accordingly, make them all void and use
async_error in their callers instead of their return values.
Moreover, since async_error is updated concurrently without locking
during asynchronous suspend and resume processing, use READ_ONCE() and
WRITE_ONCE() for accessing it in those places to ensure that all of the
accesses will be carried out as expected.

Pull networking fixes from Jakub Kicinski:
"Including fixes from Bluetooth, CAN, WiFi and Netfilter.
More code here than I would have liked. That said, better now than
next week. Nothing particularly scary stands out. The improvement to
the OpenVPN input validation is a bit large but better get them in
before the code makes it to a final release. Some of the changes we
got from sub-trees could have been split better between the fix and
-next refactoring, IMHO, that has been communicated.
We have one known regression in a TI AM65 board not getting link. The
investigation is going a bit slow, a number of people are on vacation.
We'll try to wrap it up, but don't think it should hold up the
release.
Current release - fix to a fix:
- Bluetooth: L2CAP: fix attempting to adjust outgoing MTU, it broke
some headphones and speakers
Current release - regressions:
- wifi: ath12k: fix packets received in WBM error ring with REO LUT
enabled, fix Rx performance regression
- wifi: iwlwifi:
- fix crash due to a botched indexing conversion
- mask reserved bits in chan_state_active_bitmap, avoid FW assert()
Current release - new code bugs:
- nf_conntrack: fix crash due to removal of uninitialised entry
- eth: airoha: fix potential UaF in airoha_npu_get()
Previous releases - regressions:
- net: fix segmentation after TCP/UDP fraglist GRO
- af_packet: fix the SO_SNDTIMEO constraint not taking effect and a
potential soft lockup waiting for a completion
- rpl: fix UaF in rpl_do_srh_inline() for sneaky skb geometry
- virtio-net: fix recursive rtnl_lock() during probe()
- eth: stmmac: populate entire system_counterval_t in get_time_fn()
- eth: libwx: fix a number of crashes in the driver Rx path
- hv_netvsc: prevent IPv6 addrconf after IFF_SLAVE lost that meaning
Previous releases - always broken:
- mptcp: fix races in handling connection fallback to pure TCP
- rxrpc: assorted error handling and race fixes
- sched: another batch of "security" fixes for qdiscs (QFQ, HTB)
- tls: always refresh the queue when reading sock, avoid UaF
- phy: don't register LEDs for genphy, avoid deadlock
- Bluetooth: btintel: check if controller is ISO capable on
btintel_classify_pkt_type(), work around FW returning incorrect
capabilities
Misc:
- make OpenVPN Netlink input checking more strict before it makes it
to a final release
- wifi: cfg80211: remove scan request n_channels __counted_by, it's
only yielding false positives"

Pull power management fixes from Rafael Wysocki:
"These address three issues introduced during the current development

NVMe devices from multiple vendors appear to get stuck in a reset state
that we can't get out of with an NVMe level Controller Reset. The kernel
would report these with messages that look like:
Device not ready; aborting reset, CSTS=0x1
These have historically required a power cycle to make them usable
again, but in many cases, a PCIe FLR is sufficient to restart operation
without a power cycle. Try it if the initial controller reset fails
during any nvme reset attempt.

When allocating IOVA the candidate range gets aligned to the target
alignment. If the range is close to ULONG_MAX then the ALIGN() can
wrap resulting in a corrupted iova.
Open code the ALIGN() using get_add_overflow() to prevent this.
This simplifies the checks as we don't need to check for length earlier
either.
Consolidate the two copies of this code under a single helper.
This bug would allow userspace to create a mapping that overlaps with some
other mapping or a reserved range.

The deadlock appears in a stack trace like:
virtnet_probe()
rtnl_lock()
virtio_config_changed_work()
netdev_notify_peers()
rtnl_lock()
It happens if the VMM sends a VIRTIO_NET_S_ANNOUNCE request while the
virtio-net driver is still probing.
The config_work in probe() will get scheduled until virtnet_open() enables
the config change notification via virtio_config_driver_enable().

The per-CPU variable ppp::xmit_recursion is protecting against recursion
due to wrong configuration of the ppp unit. The per-CPU variable
relies on disabled BH for its locking. Without per-CPU locking in
local_bh_disable() on PREEMPT_RT this data structure requires explicit
locking.
The ppp::xmit_recursion is used as a per-CPU boolean. The counter is
checked early in the send routing and the transmit path is only entered
if the counter is zero. Then the counter is incremented to avoid
recursion. It used to detect recursion on channel::downl and
ppp::wlock.
Create a struct ppp_xmit_recursion and move the counter into it.
Add local_lock_t to the struct and use local_lock_nested_bh() for
locking. Due to possible nesting, the lock cannot be acquired
unconditionally but it requires an owner field to identify recursion
before attempting to acquire the lock.
The counter is incremented and checked only after the lock is acquired.
Since it functions as a boolean rather than a count, and its role is now
superseded by the owner field, it can be safely removed.

Implement phase offset monitor feature to allow a user to monitor
phase offsets across all available inputs.
The device firmware periodically performs phase offsets measurements for
all available DPLL channels and input references. The driver can ask
the firmware to fill appropriate latch registers with measured values.
There are 2 sets of latch registers for phase offsets reporting:
1) DPLL-to-connected-ref: up to 5 registers that contain values for
phase offset between particular DPLL channel and its connected input
reference.
2) selected-DPLL-to-ref: 10 registers that contain values for phase
offsets between selected DPLL channel and all available input
references.
Both are filled with single read request so the driver can read
DPLL-to-connected-ref phase offset for all DPLL channels at once.
This was implemented in the previous patch.
To read selected-DPLL-to-ref registers for all DPLLs a separate read
request has to be sent to device firmware for each DPLL channel.
To implement phase offset monitor feature:
* Extend zl3073x_ref_phase_offsets_update() to select given DPLL channel
in phase offset read request. The caller can set channel==-1 if it
will not read Type2 registers.
* Use this extended function to update phase offset latch registers
during zl3073x_dpll_changes_check() call if phase monitor is enabled
* Extend zl3073x_dpll_pin_phase_offset_check() to check phase offset
changes for all available input references
* Extend zl3073x_dpll_input_pin_phase_offset_get() to report phase
offset values for all available input references
* Implement phase offset monitor callbacks to enable/disable this
feature

Add support to get/set embedded sync for both input and output pins.
The DPLL is able to lock on input reference when the embedded sync
frequency is 1 PPS and pulse width 25%. The esync on outputs are more
versatille and theoretically supports any esync frequency that divides
current output frequency but for now support the same that supported on
input pins (1 PPS & 25% pulse).
Note that for the output pins the esync divisor shares the same register
used for N-divided signal formats. Due to this the esync cannot be
enabled on outputs configured with one of the N-divided signal formats.

As part of the resume or GT reset, the PF driver schedules work
which is then used to complete restarting of the SR-IOV support,
including resending to the GuC configurations of provisioned VFs.
However, in case of short delay between those two actions, which
could be seen by triggering a GT reset on the suspened device:
$ echo 1 > /sys/kernel/debug/dri/0000:00:02.0/gt0/force_reset
this PF worker might be still busy, which lead to errors due to
just stopped or disabled GuC CTB communication:

The check would fail if the address is unaligned, but not when

been `buf + offset`. To make it more readable and also drop the

Currently all paths that set err and then check it for an error
perform immediate returns, hence err always zero at the end of
the function _mlx5r_umr_zap_mkey. The return expression
err ? err : nblocks has a redundant check on the err since err
is always zero, so just return nblocks instead.

Commit 2df7168717b7 ("dm: Always split write BIOs to zoned device
limits") updates the device-mapper driver to perform splits for the
write BIOs. However, it did not address the cases where DM targets do
not emulate zone append, such as in the cases of dm-linear or dm-flakey.
For these targets, when the write BIOs span across zone boundaries, they
trigger WARN_ON_ONCE(bio_straddles_zones(bio)) in
blk_zone_wplug_handle_write(). This results in I/O errors. The errors
are reproduced by running blktests test case zbd/004 using zoned
dm-linear or dm-flakey devices.
To avoid the I/O errors, handle the write BIOs regardless whether DM
targets emulate zone append or not, so that all write BIOs are split at
zone boundaries. For that purpose, drop the check for zone append
emulation in dm_zone_bio_needs_split(). Its argument 'md' is no longer
used then drop it also.

Same as done for raid0, set chunk_sectors limit to appropriately set the
atomic write size limit.
Setting chunk_sectors limit in this way overrides the stacked limit
already calculated based on the bottom device limits. This is ok, as
when any bios are sent to the bottom devices, the block layer will still
respect the bottom device chunk_sectors.

Currently we use min io size as the chunk size when deciding on the
atomic write size limits - see blk_stack_atomic_writes_head().
The limit min_io size is not a reliable value to store the chunk size, as
this may be mutated by the block stacking code. Such an example would be
for the min io size less than the physical block size, and the min io size
is raised to the physical block size - see blk_stack_limits().
The block stacking limits will rely on chunk_sectors in future,
so set this value (to the chunk size).

Have nvmet_req_init() and req->execute() complete failed commands.
Description of the problem:
nvmet_req_init() calls __nvmet_req_complete() internally upon failure,
e.g., unsupported opcode, which calls the "queue_response" callback,
this results in nvmet_pci_epf_queue_response() being called, which will
call nvmet_pci_epf_complete_iod() if data_len is 0 or if dma_dir is
different from DMA_TO_DEVICE. This results in a double completion as
nvmet_pci_epf_exec_iod_work() also calls nvmet_pci_epf_complete_iod()
when nvmet_req_init() fails.
Steps to reproduce:
On the host send a command with an unsupported opcode with nvme-cli,
For example the admin command "security receive"
$ sudo nvme security-recv /dev/nvme0n1 -n1 -x4096
This triggers a double completion as nvmet_req_init() fails and
nvmet_pci_epf_queue_response() is called, here iod->dma_dir is still
in the default state of "DMA_NONE" as set by default in
nvmet_pci_epf_alloc_iod(), so nvmet_pci_epf_complete_iod() is called.
Because nvmet_req_init() failed nvmet_pci_epf_complete_iod() is also
called in nvmet_pci_epf_exec_iod_work() leading to a double completion.
This not only sends two completions to the host but also corrupts the
state of the PCI NVMe target leading to kernel oops.
This patch lets nvmet_req_init() and req->execute() complete all failed
commands, and removes the double completion case in
nvmet_pci_epf_exec_iod_work() therefore fixing the edge cases where
double completions occurred.
