As part of Ib22dfa375217a48448c5a7872a9a2ed154dd862f, reviewer has
provided comments to make __hdd_stop and __hdd_hostapd_stop symmetrical
to avoid any logical issue.
Along with above point, fix hdd_init_ap_mode to check event_flags
instead of sap context to find out if session is already opened and
initialized.

wlan_serialization_remove_all_cmd_from_queue() is getting called
two times which causes reference count to be decreased two times.
1) 1st time from sme_stop() -> purge_sme_cmd_list()
-> wlan_serialization_remove_all_cmd_from_queue()
2) 2nd time from wlan_serialization_vdev_obj_destroy_notification()
-> serialization_purge_cmd_list()
-> wlan_serialization_remove_all_cmd_from_queue()
1st path has been there for quite a long time as per the old serialization
design but with new serialization design, it won't be required.

In wlan_hdd_cfg80211_set_fils_config, incoming fils configs
are copied into local buffers. Buffer allocations happen with
internal length definitions, while lengths are checked against
definitions from WMI API's. This may cause a buffer overwrite
for fils erp realm buffer.
Use the same definitions for length checks that are used for
allocations.

There is an interface idle work that stops the driver module in cases of
adapter inactivity. This work grabs the iface_change_lock, which is also
grabbed before synchronously cancelling the interface idle work. This can
cause a deadlock situation where cancelling the work never finishes,
because the caller holds the lock the work needs in order to complete.
Hoist the calls to cancel the work out of locked regions to avoid the
potential deadlock situation.

Currently, the interface idle (aka interface change) timeout uses a
qdf_mc_timer. This dependency on the MC thread means the MC thread
cannot be shutdown as part of the interface idle timeout work. This
wastes resources, and leads to the init/deinit paths to be out of sync
with respect to starting and stopping the MC thread. To address these
issues, use a delayed work to schedule the interface idle work instead
of a qdf_mc_timer.

In function wma_unified_debug_print_event_handler, datalen is
received from the FW and is used to mem copy data buffer from
FW into the local array dbgbuf. Since dbgbuf is a local array
of size 500 bytes, if datalen is greater than 500, buffer
overwrite occurs during memcpy.
Add sanity check to limit datalen to 500 bytes if value received
is greater than 500 bytes.

Currently, the MC thread is started once, on the transition from the

The current check for peer_num in wma_get_ll_stats_ext_buf is
incorrect and subtracts total_peer_len from WMI_SVC_MSG_MAX_SIZE
and then divides it by the size of peer stats struct.
Fix the check in such a way that peer num is not greater than
WMI_SVC_MSG_MAX_SIZE divided by the sum of total_peer_len
and size of peer stats struct.

In set default key operation module, under SAP mode, there are
conditional checks on key type information derived from the
Station's context. Also in get/add key operations SAP or STA
context pointers are derived without knowing the device mode
first, which is incorrect.
Derive key type info from SAP context in set default key and
derive station or sap context pointers only after knowing the
device mode.

Android framwork decides when to put driver in power
save state. When it disables powersave driver starts
a timer to re-enter power save which is not required.
Fix this by not starting auto ps timer for power save
disable case. Framwork sends disable power save in
disconneced state and driver returns error, Due to
this firmware power state is still in BMPS and it
reenables power save immediately after connection
and this causes power state mismatch between framwork
and driver/firmware. Fix is to handle full power
request in disconnected state and send this full power
request to firmware as it can handle it.

This can be problematic for builds which include hotfixes
(cherry-picks). Include the Change-Ids of every cherry-pick commit since
the last non-cherry-pick commit. This allows developers to quickly
identify the checkout point used to make the build, as well as any
