Currently the driver checks that DBS for connection
is allowed or not, and on that basis rejects the scan,
but it may happen that FW supports DBS, and DBS for
scan is enabled in the ini, but the DBS for connection
is disabled.
In that case the diver opts for non-dbs scan.
Fix is to allow DBS scan in case of DBS scan enabled in ini.

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

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.

Currently, the vdev connection status is checked by getting

state then vdev connected status is sent as true. It can happen
vdev is present and bss peer is deleted after getting the bss peer
from vdev pointer. Then bss peer can not be dereferenced to get the
its status.
Instead remove all the duplicate api's tdls_is_vdev_connected,

Consider a WDS Repeater(RE) connected to the Root on a DFS channel and
reverse CSA is enabled. When RE detects radar, it adds the radar infected
channel to its NOL list and it informs the Root of the radar detect. Let
the target channel chosen by the Root be a DFS channel.The RE on receiving
the RCSA, brings down the STA vap and begins to scan again.
The scan is initiated from the supplicant (wlan_cfg80211_scan) and it
provides all the supported channels including the NOL channels.
(supplicant is unaware of the radar detect and NOL channels).
As the scan channel list sent to the FW includes NOL channels, FW reports
DFS SCAN VIOLATION and all DFS channels are blocked in RE.
The supplicant keeps sending the same scan list but scan is never
successful and thus the RE does not connect back to the Root.
To fix the DFS violation, remove the NOL channel(s) from the scan channel
list before sending the list to the FW.
