As a part of driver load, a device file /dev/wlan is created to provide
control to the userspace to turn ON and OFF the wifi. This file also acts
as a holding-the-context entity for the userspace till the host driver
and firmware are properly up and ready as a part of driver probe.
In a scenario where driver probe fails, there can be an occurrence of a
race condition wherein the driver gets unloaded in the probe error path
before the userspace releases the control of the /dev/wlan file.
This leads to a NULL pointer access as the file memory gets deleted as
part of driver unload.
To achieve a serialization between the userspace context, where file is
being accessed, and the driver context, where unload is being done,
implement a simple reference counting through which the driver unload
waits till userspace cleanly releases access to the file.

In case of sap big data logging, it is assumed that legacy
dot11 mode is always supported, if the connection is done
in 11ax and if station does not shares the ht and vht info
in that case legacy dot11 mode should not be updated as it
is possible that sta is only 11ax supported.

While sending tx frame WMA_IGTK_KEY_INDEX_4 is used to get the
igtk key, but the WMA_IGTK_KEY_INDEX_5 is also valid igtk key index
and thus if igtk index passed is WMA_IGTK_KEY_INDEX_5 the get igtk
always fails.
So during set key store the igtk key index and use the same to get
igtk key.

After roaming, new pe session is created and based on the authentication
status received in the roam synch indication, the is_key_installed flag
is set. But this flag is not set to sta ds after roaming.
This causes deauth frame to roamed AP sent out unencrypted after
roam.
Set the key installed flag to sta ds if the auth status in
roam synch indication is authenticated.
If the status is connected, this flag will be set in the
set key response path.

Currently, NDP peer entry is cached in dph table when an NDP
indication is received. Existence of this entry in the table
is used to know if the NDP session is still valid and peer cleanup
happens based on that. It removes the entry from dph table once the
cleanup is done in WMA_DELETE_STA_RSP handler. Below are the two
cases to initiate cleanup on an NDP,
1. When NDP_END indication is received from firmware
2. When NDP confirm is received with a failure from firmware
There can be a scenario where these two events happen back to
back for the same peer. An event might attempt to remove peer with
wma_remove_peer while the other event has already removed and just
before deleting the entry from dph table.
So check for the existence of peer entry in objmgr in
wma_remove_peer before proceeding for the peer removal. Try to
remove peer only if it's present.

or not.

In case eCsrForcedDeauthSta from NB is completed, eWNI_SME_DEAUTH_RSP
will remove all pending eSmeCommandWmStatusChange type commands from

Fix is to don't remove pending eSmeCommandWmStatusChange type
commands when NB disconnect complete from eWNI_SME_DEAUTH_RSP.

Assume in case of STA + STA, where STA1 is on 2G band
and STA2 is on 5G band.
While switching STA1 to STA2, hdd_reg_set_band issue
disconnect, in order to change band (say 2G to 5G) and
start processing roam scan offload request to make sure
roaming gets enable on only one STA at a time.
eWNI_SME_DISASSOC_REQ and eWNI_SME_ROAM_SCAN_OFFLOAD_REQ
msg get posted to lim back to back through a single thread.
HOST starts processing DISASSOC_REQ first and waits for
tx_completion ACK for disassoc frame. Ideally, Host should
process eWNI_SME_ROAM_SCAN_OFFLOAD_REQ before getting ACK
for disassoc frame.
In case if DUT immediately gets disassoc ACK, DUT complete
disassoc req and then gets chance to process SCAN_OFFLOAD req.
Once DUT enters into Disconnection state, HOST never sends
RSO stop command to FW and leads to assert in fw.
Fix is to synchronize eWNI_SME_DISASSOC_REQ and
eWNI_SME_ROAM_SCAN_OFFLOAD_REQ command to make sure RSO stop
gets process first followed by Disconnection/deauth.

Host receives ROAM_SYNCH event from FW when MLME SM
is in ST-RESTART_PROG state while processing ht_width_switch
request. This results in MLME SM not able to send SYNC IND failure
to FW and leads to assert in FW.
Below fix are required to handle the above situation:
1. Avoid VDEV-RESTART while handling ht_width_switch if
roaming is in progress on the same vdev.
2. If Vdev is not UP then send roam sync failure to FW to
avoid assert in FW.
3. If ht_width_switch req fails then make sure host initiates
disconnection.
