Currently, ucfg_scan_register_pno_cb and ucfg_scan_get_scan_id
do not do null validation for scan object which can lead to null
pointer dereference. wlan_psoc_get_scan_obj_fl returns null in case
of invalid component id or null psoc and that null scan object is
dereferenced due to missing null validation.
Add null pointer check for scan object in ucfg_scan_register_pno_cb
and ucfg_scan_get_scan_id. Return zero scan id from ucfg_scan_get_scan_id
in case of null scan object.

Currently dwell time is determined by scan policy flags from kernel.
Sometimes when we suspect the scan result is not full enough, we need
to set dwell time by force through ini.
Add ini to decide whether to honour NL80211 scan policy flags, so that
we can disable dwell time changed by scan policy flag from kernel.

Adaptive 11r is a feature by which the network supports 11r
even though the bss doesn't advertise 11r. This is done with the
help of advertising vendor specific adaptive 11r IE and MD IE
in the beacon/probe. When vendor specific adaptive 11r
IE (oui 0x00 40 96 type 0x2C) is present in the beacon/probe,
and 1st bit of the IE data is set to 1, then the BSS supports
adaptive 11r.
The BSS advertises, non-11r akm in RSN IE and user space will
send the 11r akm in the connect start. So the scan module
shouldn't filter out the candidate adaptive 11r supported BSS
with AKM mismatch reason.
Add changes in scan module to parse the Vendor specific adaptive
11r IE and copy it to the scan_entry ie_list. Check if
negotiated akm is non-11r akm, and the filter akm sent from csr
is a 11r akm (which is received from user space), then mark the
bss as matching.

the driver updates the active dwell time for the scan

Fix is to not update the concurrency params if the scan

are many, then the STA will receive many beacons, whose

the time to process the beaocns is larger than their
process timeout.

not allocated
2. Make memory allocation in path of beacon process

AP is configured to operate in Channel 100(HT80), and Zero Wait DFS
is enabled. Once PreCAC is complete on DFS Channels,inject radar in
Channel 100 and AP moves to another DFS channel 116 and beacons
immediately but station associated to AP still does a scan again.
When the station receives the Channel Switch Announcement from AP, it
dissociates from the AP and scans again.
Maximum Switch time Information Element can be used by the Station to
to know if the AP has done PreCAC on target channel. Maximum Switch Time
IE is part of AP's beacon and is the sum of CAC timeout on the target
channel and 1 beacon interval.
If PreCAC is done on target channel, the CAC timeout is zero and Maximum
Switch time IE is equal to 1 beacon interval. This element is sent to
Station along with Channel Switch Announcement. The Station receives the
maximum channel switch time element. If the value of maximum channel switch
time element is less then or equal to beacon interval, the station
associates with the AP seamlessly without dissociation. If the value of
the Maximum Channel Switch Time IE is greater than 1 beacon interval, then,
the Station has to dissociate from the AP since, ZeroCAC has not been done
by the AP.
