4e5cfb2ac9 qcacmn: Add vdev param to configure NAN feature bitmap to firmware
Define a new vdev param to set corresponding bit to enable/disable
a particular NAN feature.
Currently, Framework configures NAN DW as 4 seconds when the
device is in sync role and the screen is off. But customers might
want this to be 512ms always irrespective of screen off/on.
Send the vdev param on NAN vdev by setting the "bit 0" to 0 to
indicate firmware to ignore framework configured DW value and
consider the firmware default value.

ace59f2d1f qcacmn: Update OCAC completion Host structure and processing routine
The OCAC completion event 'wmi_vdev_adfs_ocac_complete_event_fixed_param'
has been updated to include center frequencies of 2 segments in MHz for
165Mhz Agile mode.

Update the corresponding Host OCAC completion data structure
'vdev_adfs_complete_status' to include 2 center frequencies to support
165MHz Agile mode.

Also FW might send a delayed OCAC completion status after the Host has
configured a new agile channel. So all the OCAC completion events should be
validated if the status is received for the current agile channel.

Update the OCAC completion processing API to include 2 center frequencies
and chwidth so that, it is possible to check if the OCAC completion status
is received on current agile channel or an obsolete agile channel.

0497ce7057 qcacmn: Fix buffer overflow while memcpy of pmk_ext
Due to commit : Ia630580bba050513800e3acac875baf937ec8d14
while processing RSO command driver fills the pmk_ext_len without
checking the pmk_len. If pmk_len is NULL then pmk_ext_len gets
filled with a negative value and after this while doing the
memcpy it will cause the buffer overflow due to invalid length.

Fix is to verify pmk_len before filling the value in pmk_ext_len.

Whenever a wmi even it received the tlv received from the firmware
will be sanitized, if there is any error the event would be dropped.
This dropping of the event can give side effects in the host/firmware

why the tlv is not received properly.

Enhanced Multi-BSSID Advertisement is an enhancement to the
existing Multi-BSSID feature in terms of advertising
non-transmitted bssid profile using the transmitted bssid
beacon. Mandatory inclusion of RNR IE in lower-band AP
beacon to support Out-of-Band Advertisement of colocated
6Ghz AP may impose limitation in the beacon size. EMA AP
provides a standardized way of overcoming such a limitation

Relevant WMI changes are:
1. Support of EMA AP service bit in wmi_service_ready_ext
2. Support of 32-bit ema_params in wmi_bcn_tmpl_cmd_fixed_param
to signal ema_beacon_profile_periodicity, ema_beacon_tmpl_idx,
ema_first_tmpl and ema_last_tmpl to firmware while sending the
beacon template
3. Support of 32-bit WMI resource-config params in INIT cmd
to signal number of max transmitting BSSs and max profile
periodicity

2b12f986bb qcacmn: Fix NULL pointer dereference of roam stats event param buf
In extract_roam_scan_ap_stats_tlv, if param buf is null, null
pointer dereference can happen while trying to access
num_roam_ap_info in the error message print.

Return failure if param_buf is NULL

0150333a89 qcacmn: Abort only host scans on roam start notification
The roam sequence in LFR-3.0 is roam scan start notification
from firmware followed by roam start indication and then
roam synch,roam synch frame events. Roam start is sent
after candidate selection and host driver will disable
queues when roam start is received.
But for emergency roam trigger, firmware sends roam start
indication directly without notifying roam scan start to disable
data path queues immediately after deauth received from the AP.
So roam start is received before roam scan is started at firmware
and before candidate selection is done.

After roam start notification, host sends scan abort for all scan
on vdev by setting scan command request type to
WMI_SCN_STOP_VAP_ALL. This results in roam scan getting aborted at
firmare in emergency deauth roaming case and roaming fails.

Introduce new vdev id value based on which the scan module will
abort only host triggered scans setting the flag
WMI_SCN_STOP_HOST_VAP_ALL in the scan request.

3765db635c qcacmn: Add ini to enable/disable self roaming
Currently the driver allows roaming to the BSSID
which it is already connected, which can lead to
many unexpected behaviour, for eg. if the SAP
to which the DUT is connected turns off, then the
DUT would try to roam to other BSSID of the same
SSID, and in case the SAP turns on back in time,
then the DUT would re-associate to the same BSSID.
Now if the subnet may change, and since the DHCP
does not happen again in roaming, it would then
lead to NUD failure.

Fix is to introduce an ini to allow/disallow
roaming to the same BSSID.
