55cc84421c rtw88: add ciphers to suppress error message
Though hardware isn't implement CCMP-256, GCMP and GCMP-256, it's possible
to fallback to use software de-/en-cryption implemented by mac80211.

Without adding these chipers, kernel log will show something if we connect
to a WPA3 enterprise AP, likes
  wlan0: failed to set key (1, ff:ff:ff:ff:ff:ff) to hardware (-524)

6eab0ba99b rtw88: avoid holding mutex for cancel_delayed_work_sync()
Driver could possibly be dead-locked while canceling works with
*_sync() with mutex lock held. Those cancel_delayed_work_sync()
functions will wait until the work is done, but if we hold the
lock, they will never acquire the lock.

To prevent this, simply release the lock and acquire again after
the works have been canceled. And to avoid the works being queued
again, check if the device is at RTW_FLAG_RUNNING state, otherwise
just return and do nothing.

398b9bdab2 rtw88: move rtw_enter_ips() to the last when config
When driver is coming up, mac80211 will set changed as ~0 (0xffffffff),
and driver could enter IDLE state (power off) before switching channel or
other config event. So move rtw_enter_ips() to the last, to make sure the
driver completed the config events before going to IDLE state.

So, moves leave/enter IPS config to be first/last one according to flag
IEEE80211_CONF_IDLE. If there're more configureations we want to add in
the future, they must locate between leave/enter IPS.

to keep it in TLV. Simplify scan command processing moving
most part of its parameters into a fixed part of
qlink_cmd_scan message.

Use fixed dwell time values for normal scan when device is not
connected, and allow wireless card decide on dwell times by
itself if it's operating as a STA and is connected. When
connected, card can select dwell times dynamically based on
traffic conditions to get best results.

a3ebb0335c qtnfmac: use MAJOR.MINOR format for firmware protocol
Use MAJOR.MINOR format for QLink firmware protocol. MAJOR part is
incremented when backward compatibility is broken. Normally this
part should not be incremented unless there is a good reason for
that. MINOR part is incremented each time when new features are
added to qlink.h, e.g. new TLVs, events, commands. These changes
should not break backward compatibility. For instance, older
firmware versions may not be able to parse new flags or send new
types of events, but this does not impact normal system operations.

As part of initialization sequence, driver requests protocol version
from firmware and refuses to start in case there is a mismatch in MAJOR
part of the version.

cc4255eff5 iwlwifi: mvm: avoid use after free for pmsr request
When a FTM request is aborted, the driver sends the abort command to
the fw and waits for a response. When the response arrives, the driver
calls cfg80211_pmsr_complete() for that request.
However, cfg80211 frees the requested data immediately after sending
the abort command, so this may lead to use after free.

Fix it by clearing the request data in the driver when the abort
command arrives and ignoring the fw notification that will come
afterwards.

6bd5fa332a iwlwifi: mvm: update the DTS measurement type
Till now, the driver asked the fw for a DTS measurement in automatic
mode. This triggered a flow in which the fw actively measured the
temperature.  This is not needed anymore, as the fw performs
measurements by itself, without the driver triggering them, and the
current cadence in which the fw performs such measurements is
sufficient.

In addition, in some time-sensitive scenarios, in which the driver asks
the fw for an active measurement twice in a short time (<100ms), the fw
asserts with code 0x20100801.

Change the DTS measurement to _WITHOUT_MEASURE instead, so the fw will
respond with the last measurement it has performed.

197288d5ba iwlwifi: don't throw error when trying to remove IGTK
The IGTK keys are only removed by mac80211 after it has already
removed the AP station.  This causes the driver to throw an error
because mac80211 is trying to remove the IGTK when the station doesn't
exist anymore.

The firmware is aware that the station has been removed and can deal
with it the next time we try to add an IGTK for a station, so we
shouldn't try to remove the key if the station ID is
IWL_MVM_INVALID_STA.  Do this by removing the check for mvm_sta before
calling iwl_mvm_send_sta_igtk() and check return from that function
gracefully if the station ID is invalid.

1754c4f60a libertas: make lbs_ibss_join_existing() return error code on rates overflow
Commit e5e884b426 ("libertas: Fix two buffer overflows at parsing bss
descriptor") introduced a bounds check on the number of supplied rates to
lbs_ibss_join_existing() and made it to return on overflow.

However, the aforementioned commit doesn't set the return value accordingly
and thus, lbs_ibss_join_existing() would return with zero even though it
failed.

Make lbs_ibss_join_existing return -EINVAL in case the bounds check on the
number of supplied rates fails.

Commit e5e884b426 ("libertas: Fix two buffer overflows at parsing bss

lbs_ibss_join_existing().

Unfortunately, it introduced a return path from within a RCU read side
critical section without a corresponding rcu_read_unlock(). Fix this.

c2f9a4e4a5 iwlegacy: ensure loop counter addr does not wrap and cause an infinite loop
The loop counter addr is a u16 where as the upper limit of the loop
is an int. In the unlikely event that the il->cfg->eeprom_size is
greater than 64K then we end up with an infinite loop since addr will
wrap around an never reach upper loop limit. Fix this by making addr
an int.
