osif priv is allocated as part of the vdev object and freed as part of
the logical vdev deletion. There is a race condition where in a
component
holding the reference to the vdev is trying to do an operation using
the osif priv. But in the other thread osif priv can be freed.
This can lead to null pointer exception.
Hence, move the osif priv deletion to the vdev physical destroy.

in wma_apf_read_work_memory_event_handler() apf read callback is

During extraction of apf attributes there is no NULL check of data
tlv when data length is non-zero. If the firmware message is wrongly
crafted with non-zero length in fixed param and NULL data then NULL
pointer dereference is seen in apf read callback.
To address this, avoid copy when data is NULL and data length is

Deadlock happens when control path takes scn_lock and calls
dp_peer_unref_delete() which in tern tries to acquire peer_ref_mutex.
At the same time, if other core starts handling peer_unmap by acquiring
peer_ref_mutex and calls dp_reset_and_release_peer_mem() which in turn
calls ol_ath_node_free() and tries to acquire scn_lock leading to a
deadlock.
Fix this by unlocking peer_ref_mutex before calling

Add a QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_BEACON_REPORTING
to implement beacon reporting feature. Different operations required to
implement this feature can be specified in
QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_OP_TYPE.
Userspace requests the driver/firmware to periodically report received
Beacon frames whose BSSID matches the current connected BSS's MAC
address. If userspace requests the driver/firmware to send beacon
reports actively, the driver encapsulates the details of the beacon in
an event and sends it to userspace asynchronously. Otherwise, the driver
will only update the beacon in cfg80211 scan cache but will not send any
event to userspace.
If this command is not issued, the current behavior of the
driver/firmware is to update the cfg80211 scan cache only when there is
a scan issued by the host in progress or whenever there is a change in
IEs of the Beacon frames from the current connected BSS.
The userspace requests the driver/firmware to stop reporting beacons
when reporting is not required anymore. If the driver/firmware is not
able to receive Beacon frames because of other Wi-Fi operations such as
off-channel activities, etc., the driver/firmware sends a pause event to
userspace and stops reporting Beacon frames. The driver/firmware
indicates whether the beacon reporting automatically resumes later by
using the QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_AUTO_RESUMES flag. If
userspace doesn't want the beacon reporting to be resumed automatically,
userspace can send QCA_WLAN_VENDOR_BEACON_REPORTING_OP_STOP command to
the driver to stop beacon reporting.

The release ref APIs for an object first checks,
if the caller is holding a ref, and if yes, it decrements
the count.
If not, there is an error print and an assert, and if the assert is
disabled, the total ref count is decremented in the code, which could
lead to the object getting destoyed, even when it is being used or
some other component holding its ref.
So, if release ref API for an object is called by a component, which
is not holding the ref, we should return, so its handled correctly
even when assert is disabled.

Mc timer is used to initialize the p2p roc timer.
And the actual timer runs in the soft irq thread and
when the timer exipres it posts the message to mc thread.

It calls the del_timer internally to delete the timer.
del_timer() ensures that the given timer is not queued
to run anywhere in the system. But the callback may
be running on another CPU core can create race conditions.
So use del_timer_sync to delete the roc timer.

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.

CCE stats are reported across rings today. Since HKv2 is a SMP, it
creates the possibility of missing stats when two or more CPUs are
updating the counters for the same protocol type. In order to avoid
this, we can either use locks or store stats on a per-CPU basis.
Since tagging happens on the core data path, locks are not preferred.
Instead, we use a per-ring counter, since each CPU operates on a REO
ring. Exception packets today go to Ring-0 (also normal rx Reo-0
go to Ring-0). Hence tags are maintained separately for exception
ring as well.
