ath11k: reduce the wait time of 11d scan and hw scan while add interface
MAINTAINERS: update iwlwifi driver maintainer
iwlwifi: iwl-dbg: Use del_timer_sync() before freeing

(cherry picked from commit 1f682dc9fb in wireless-next)
Currently ath11k will wait 11d scan complete while add interface in
ath11k_mac_op_add_interface(), when system resume without enable
wowlan, ath11k_mac_op_add_interface() is called for each resume, thus
it increase the resume time of system. And ath11k_mac_op_hw_scan()
after ath11k_mac_op_add_interface() also needs some time cost because
the previous 11d scan need more than 5 seconds when 6 GHz is enabled,
then the scan started event will indicated to ath11k after the 11d
scan completed.
While 11d scan/hw scan is running in firmware, if ath11k update channel
list to firmware by WMI_SCAN_CHAN_LIST_CMDID, then firmware will cancel
the current scan which is running, it lead the scan failed. The patch
commit 9dcf6808b2 ("ath11k: add 11d scan offload support") used
finish_11d_scan/finish_11d_ch_list/pending_11d to synchronize the 11d
scan/hw scan/channel list between ath11k/firmware/mac80211 and to avoid
the scan fail.
Add wait operation before ath11k update channel list, function
ath11k_reg_update_chan_list() will wait until the current 11d scan/hw
scan completed. And remove the wait operation of start 11d scan and
waiting channel list complete in hw scan. After these changes, resume
time cost reduce about 5 seconds and also hw scan time cost reduced
obviously, and scan failed not seen.
The 11d scan is sent to firmware only one time for each interface added
in mac.c, and it is moved after the 1st hw scan because 11d scan will
cost some time and thus leads the AP scan result update to UI delay.
Currently priority of ath11k's hw scan is WMI_SCAN_PRIORITY_LOW, and
priority of 11d scan in firmware is WMI_SCAN_PRIORITY_MEDIUM, then the
11d scan which sent after hw scan will cancel the hw scan in firmware,
so change the priority to WMI_SCAN_PRIORITY_MEDIUM for the hw scan which
is in front of the 11d scan, thus it will not happen scan cancel in
firmware.

The ieee80211_tx_info_clear_status() helper also clears the rate counts and
the driver-private part of struct ieee80211_tx_info, so using it breaks
quite a few other things. So back out of using it, and instead define a
ath-internal helper that only clears the area between the
status_driver_data and the rates info. Combined with moving the
ath_frame_info struct to status_driver_data, this avoids clearing anything
we shouldn't be, and so we can keep the existing code for handling the rate
information.
While fixing this I also noticed that the setting of
tx_info->status.rates[tx_rateindex].count on hardware underrun errors was
always immediately overridden by the normal setting of the same fields, so
rearrange the code so that the underrun detection actually takes effect.
The new helper could be generalised to a 'memset_between()' helper, but
leave it as a driver-internal helper for now since this needs to go to
stable.

The ath9k driver was not properly clearing the status area in the
ieee80211_tx_info struct before reporting TX status to mac80211. Instead,
it was manually filling in fields, which meant that fields introduced later
were left as-is.
Conveniently, mac80211 actually provides a helper to zero out the status
area, so use that to make sure we zero everything.
The last commit touching the driver function writing the status information
seems to have actually been fixing an issue that was also caused by the
area being uninitialised; but it only added clearing of a single field
instead of the whole struct. That is now redundant, though, so revert that
commit and use it as a convenient Fixes tag.

Reading through the commit history, it looks like
there is no special need why we must skip the first 4 bytes
in this trace call:
trace_ath10k_htt_rx_desc(ar, (void*)rx_desc + sizeof(u32),
hw->rx_desc_ops->rx_desc_size - sizeof(u32));
found in the function ath10k_htt_rx_amsdu_pop in the file htt_rx.c
i think the original author
(who is also the one who added rx_desc tracing capabilities
in a0883cf7e7) just wanted to trace the rx_desc contents,
ignoring the fw_rx_desc_base info field
(which is the part being skipped over).
But the trace_ath10k_htt_rx_desc later added
don't care about skipping it, so it may be good
to uniform this call to the others in the file.
But this would change the output of the trace and
thus it may be a problem for tools that rely on it.
Therefore I propose until further discussion
to just keep it as it is and just fix the pointer arithmetic bug.
Add missing void* cast to rx descriptor pointer in order to
properly skip the initial 4 bytes of the rx descriptor
when passing it to trace_ath10k_htt_rx_desc trace function.
This fixes the pointer arithmetic error detected
by Dan Carpenter's static analysis tool.

Target copies spectral report and CFR report through dbring to
host for further processing. This mechanism involves ring and
buffer management in the Host, FW, and uCode, where improper
tail pointer update issues are seen.
This dbring debug support help to debug such issues by tracking
head and tail pointer movement along with the timestamp at which
each buffer is received and replenished.
Provide a debugfs interface to enalbe/disable dbring debug
support and dump the dbring debug entries.
Also introduced a new hardware param to add dbring debugfs support
for few hardwares which are using dbings.
Usage:
echo <dbr_id> <val> > /sys/kernel/debug/ath11k/ipq8074_2/
mac0/enable_dbr_debug
dbr_id: 0 for spectral and 1 for CFR
val: 0 - disable, 1 - enable.

In some scenarios like firmware crashes during init time
and hardware gets restarted after qmi firmware ready event.
During restart, ath11k_core_qmi_firmware_ready() returns timeout.
But, this failure is not handled and ATH11K_FLAG_REGISTERED is set.
When hardware restart completed, firmware sends firmware ready event
again. Since ATH11K_FLAG_REGISTERED is already set, ath11k handles
this as core restart. Inits are not done because of previous timeout.
But ath11k_core_restart does deinit's which causes NULL pointer crash.
Fix this by handling failure from ath11k_core_qmi_firmware_ready().

REO2SW ring descriptor is currently allocated in cacheable memory.
While reaping reo ring entries on second trial after updating head
pointer, first entry is not invalidated before accessing it.
This results in host reaping and using cached descriptor which is
already overwritten in memory by DMA device (HW).
Since the contents of descriptor(buffer id, peer info and other information
bits) are outdated host throws errors like below while parsing corresponding
MSDU's and drops them.
[347712.048904] ath11k_pci 0004:01:00.0: msdu_done bit in attention is not set
[349173.355503] ath11k_pci 0004:01:00.0: frame rx with invalid buf_id 962
Move the try_again: label above ath11k_hal_srng_access_begin()
so that first entry will be invalidated and prefetched.

Hardware random number generators are supposed to use the hw_random

Replace zero-length array with flexible-array member and make use
of the struct_size() helper in kmalloc(). For example:
struct wcn36xx_hal_ind_msg {
struct list_head list;
size_t msg_len;
u8 msg[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

More than 20000 PPDU id jumping causing status ring and destination
ring processing not sync. The status ring is processed and the
destination ring is not processed. Since destination is not reaped for
so long, backpressure occurs at the destination ring.
To address this issue update the PPDU id with the latest PPDU, this
will allow the destination ring to be reaped and will prevent the
rings from getting out of sync.

Radar detection fails in the secondary 80 MHz when the
the AP's primary 80 MHz is in non-DFS region in 160 MHz.
This is due to WMI channel flag WMI_CHAN_INFO_DFS_FREQ2 is not set
properly in case of the primary 80 MHz is in non-DFS region.
HALPHY detects the radar pulses in the secondary 80 MHz only when
WMI_CHAN_INFO_DFS_FREQ2 is set.
Fix this issue by setting WMI channel flag WMI_CHAN_INFO_DFS_FREQ2
based on the radar_enabled flag from the channel context.
