When ath10k_htt_rx_pop_paddr32_list() or
ath10k_htt_rx_pop_paddr64_list() encounters an incomplete frame
(RX_ATTENTION_FLAGS_MSDU_DONE not set), it returns -EIO without
purging the skb list built up so far, leaking any skbs already
queued in the list.
Other early-exit paths within these same functions already call
__skb_queue_purge() before returning an error. Add it before the
-EIO return as well to be consistent and prevent the leak.

In ath10k_wmi_cmd_send(), the current code detects ATH10K_STATE_WEDGED
and sets ret to -ESHUTDOWN, but still proceeds to transmit pending
beacons and calls ath10k_wmi_cmd_send_nowait().
This can lead to incorrect behavior, as WMI commands and beacons are
still sent after the device has been marked as wedged, and the original
-ESHUTDOWN return value may be overwritten by the result of the send
path.
The wedged state indicates the hardware is already unreliable, and no
further interaction with firmware is expected or meaningful in this
state.
Fix this by skipping beacon transmission and the WMI send path entirely
once ATH10K_STATE_WEDGED is detected, ensuring consistent return values
and avoiding unnecessary firmware interaction.

Some firmware versions do not support the host capability QMI request.
Since this request occurs before firmware-N.bin and board-M.bin are
loaded, the quirk cannot be expressed in the firmware itself.
The root cause is unclear, but there appears to be a generation of
firmware that lacks host capability support.
Without this quirk, ath10k_qmi_host_cap_send_sync() returns
QMI_ERR_MALFORMED_MSG_V01 before loading the firmware. This error is not
fatal - Wi-Fi services still come up successfully if the request is simply
skipped.
Add a device-tree quirk to skip the host capability QMI request on devices
whose firmware does not support it.
For example, firmware build
"QC_IMAGE_VERSION_STRING=WLAN.HL.2.0.c3-00257-QCAHLSWMTPLZ-1"
on Xiaomi Poco F1 phone requires this quirk.

Recent commit [1] moved station statistics collection to an earlier stage
of the disconnect flow. With this change in place, ath10k fails to resolve
the station entry when handling a peer stats event triggered during
disconnect, resulting in log messages such as:
wlp58s0: deauthenticating from 74:1a:e0:e7:b4:c8 by local choice (Reason: 3=DEAUTH_LEAVING)
ath10k_pci 0000:3a:00.0: not found station for peer stats
ath10k_pci 0000:3a:00.0: failed to parse stats info tlv: -22
The failure occurs because ath10k relies on ieee80211_find_sta_by_ifaddr()
for station lookup. That function uses local->sta_hash, but by the time
the peer stats request is triggered during disconnect, mac80211 has
already removed the station from that hash table, leading to lookup
failure.
Before commit [1], this issue was not visible because the transition from
IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST prevented ath10k from sending
a peer stats request at all: ath10k_mac_sta_get_peer_stats_info() would
fail early to find the peer and skip requesting statistics.
Fix this by switching the lookup path to ath10k_peer_find(), which queries
ath10k's internal peer table. At the point where the firmware emits the
peer stats event, the peer entry is still present in the driver's list,
ensuring lookup succeeds.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

ath10k_sdio_fw_crashed_dump() calls ath10k_coredump_new() which requires
ar->dump_mutex to be held, as indicated by lockdep_assert_held() in that
function. However, the SDIO implementation does not acquire this lock,
unlike the PCI and SNOC implementations which properly hold the mutex.
Additionally, ar->stats.fw_crash_counter is documented as protected by
ar->data_lock in core.h, but the SDIO implementation modifies it without
holding this spinlock.
Add the missing mutex_lock()/mutex_unlock() around the coredump
operations, and add spin_lock_bh()/spin_unlock_bh() around the
fw_crash_counter increment, following the pattern used in
ath10k_pci_fw_dump_work() and ath10k_snoc_fw_crashed_dump().

to ath11k and ath12k, we want to support raw TLV payload submitted

encapsulating it within a WMI command. The opposite operation needs

Currently, ath10k has a recovery check logic. It will wait for the
last recovery to finish by wait_for_completion_timeout();
But in SDIO scenarios, the recovery function may be invoked from
interrupt context, where long blocking waits are undesirable and can
lead to system instability.
Additionally, Linux’s ordered workqueue processes one task at a time.
If a previous recovery is still queued or executing, new triggers are
ignored. This prevents accurate tracking of consecutive failures and
delays transition to the WEDGED state.
To address this, move the recovery check logic into a different
workqueue.

It appears that not all hardware/firmware implementations support
group key deletion correctly, which can lead to connection hangs
and deauthentication following GTK rekeying (delete and install).
To avoid this issue, instead of attempting to delete the key using
the special WMI_CIPHER_NONE value, we now replace the key with an
invalid (random) value.
This behavior has been observed with WCN39xx chipsets.

Commit e57b7d62a1 ("wifi: ath10k: poll service ready message before
failing") works around the failure in waiting for the service ready
message by active polling. Note the polling is triggered after initial
wait timeout, which means that the wait-till-timeout can not be avoided
even the message is ready.
A possible fix is to do polling once before wait as well, however this
can not handle the race that the message arrives right after polling.
So the solution is to do periodic polling until timeout.

Use the newly added of_reserved_mem_region_to_resource() function to
handle "memory-region" properties.
The error handling is a bit different for ath10k. "memory-region" is
optional, so failed lookup is not an error. But then an error in
of_address_to_resource() is treated as an error. However, that
distinction is not really important. Either the region is available
and usable or it is not. So now, it is just
of_reserved_mem_region_to_resource() which is checked for an error.

The leds-gpio traditionally takes a global gpio number in its platform
data, but the number assigned here is not actually such a number but
only meant to be used internally to this driver.
As part of the kernel-wide cleanup of the old gpiolib interfaces, the
'gpio' number field is going away, so to keep ath10k building, move
the assignment into a private structure instead.

In rare cases, ath10k may lose connection with the PCIe bus due to
some unknown reasons, which could further lead to system crashes during
resuming due to watchdog timeout:
ath10k_pci 0000:01:00.0: wmi command 20486 timeout, restarting hardware
ath10k_pci 0000:01:00.0: already restarting
ath10k_pci 0000:01:00.0: failed to stop WMI vdev 0: -11
ath10k_pci 0000:01:00.0: failed to stop vdev 0: -11
ieee80211 phy0: PM: **** DPM device timeout ****
Call Trace:
panic+0x125/0x315
dpm_watchdog_set+0x54/0x54
dpm_watchdog_handler+0x57/0x57
call_timer_fn+0x31/0x13c
At this point, all WMI commands will timeout and attempt to restart
device. So set a threshold for consecutive restart failures. If the
threshold is exceeded, consider the hardware is unreliable and all
ath10k operations should be skipped to avoid system crash.
fail_cont_count and pending_recovery are atomic variables, and
do not involve complex conditional logic. Therefore, even if recovery
check and reconfig complete are executed concurrently, the recovery
mechanism will not be broken.

Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

In some scenarios, the firmware may be stopped before the interface is
removed, either due to a crash or because the remoteproc (e.g., MPSS)
is shut down early during system reboot or shutdown.
This leads to a delay during interface teardown, as the driver waits for
a vdev delete response that never arrives, eventually timing out.
Example (SNOC):
$ echo stop > /sys/class/remoteproc/remoteproc0/state
[ 71.64] remoteproc remoteproc0: stopped remote processor modem
$ reboot
[ 74.84] ath10k_snoc c800000.wifi: failed to transmit packet, dropping: -108
[ 74.84] ath10k_snoc c800000.wifi: failed to submit frame: -108
[...]
[ 82.39] ath10k_snoc c800000.wifi: Timeout in receiving vdev delete response
To avoid this, skip waiting for the vdev delete response if the firmware is
already marked as unreachable (`ATH10K_FLAG_CRASH_FLUSH`), similar to how
`ath10k_mac_wait_tx_complete()` and `ath10k_vdev_setup_sync()` handle this case.

In ath10k_snoc_hif_stop() we skip disabling the IRQs in the crash
recovery flow, but we still unconditionally call enable again in
ath10k_snoc_hif_start().
We can't check the ATH10K_FLAG_CRASH_FLUSH bit since it is cleared
before hif_start() is called, so instead check the
ATH10K_SNOC_FLAG_RECOVERY flag and skip enabling the IRQs during crash
recovery.
This fixes unbalanced IRQ enable splats that happen after recovering from
a crash.
