There are two types of WLAN IPA exceptions, where WLAN driver is
involved for packet processing.
One is for RX exceptions, such as ICMP or Intra-BSS packets.
The other one is for WDI 1.0 MCC TX SW path, where packet queueing
is happening in WLAN driver.
In both cases, skb is allocated in IPA driver. If NBUF_MEMORY_DEBUG
is defined and qdf_net_buf_debug_acquire_skb() is not invoked for
the skb, qdf_nbuf_free() will trigger ASSERT to report unallocated
buffer.
For early processing of RX exceptions, dev_kfree_skb_any() needs to
be called instead of qdf_nbuf_free() otherwise above ASSERT will be
triggered.
For MCC TX SW path, ipa_free_skb() should be called to free skb to
IPA driver.

There might be a race condition between wlansap_stop_bss and
wlansap_start_bss. The tx_flow_control_timer might be created again
after released by hdd_stop_adapter which might cause the memory leak
issue.
Add mutex lock to protect the wlansap_start_bss in the function of
wlan_hdd_cfg80211_start_bss to fix incorrect state of fsm.

While calling sme_pdev_set_pcl() API, driver is passing the argument
by value. The size of the argument is 280 bytes which is not good
design.
Pass the argument by reference instead of passing it by value to make

Currently SMMU mem map table allocation size is very high and may
lead to allocation failure if system memory is fragmented or in low
memory cases. Do not allocate SMMU mem table buffer instead update
for each rx nbuff.

In the function hdd_hostapd_sap_event_cb, stainfo is obtained
from hdd_get_stainfo(). This stainfo is dereferenced later to
retrive dhcp_phase later. If the stainfo returned from the
function hdd_get_stainfo is NULL, then a possible NULL pointer
dereference could occur.
Add check to validate stainfo is not NULL.

If any userspace request is posted using request manager,
memory is allocated for that request using hdd_request_alloc
api. Now when the response of this request comes in the
registered callback, if this response is NULL then callback
returns without doing hdd_request_complete and eventually
request gets timed out and memory is released through
request_put. If the con_mode is changed before this time out
occures, con_mode_handler will try to stop_modules and will
result in mem leak detection as the memory for the request
is not released yet.
To address this issue in con_mode_handler, wait for all the
user space requests to complete before trying to stop modules.
