brcmf_fweh_process_event() sets event->datalen to the endian-swapped value of event_packet->msg.datalen, which is the same as emsg.datalen. This length is already validated in brcmf_fweh_process_event(), so there is no need to check it again upon dequeuing the event. Suggested-by:

In brcmf_p2p_notify_rx_mgmt_p2p_probereq(), chanspec is assigned before the length of rxframe is validated. This could lead to uninitialized data being accessed (but not printed). Since we already have a perfectly good endian-swapped copy of rxframe->chanspec in ch.chspec, and ch.chspec is not modified by decchspec(), avoid the extra assignment and use ch.chspec in the debug print.

Wireless device may send "channel changed" event before driver registered this device with wireless core, which will result in warnings. Once device is registered, higher layer will query channel info manually using .get_channel callback. Signed-off-by:

Do not assume whether wireless device can or can not handle switching several interfaces on a single radio to different channels. Device will handle it itself and will return appropriate error code. Signed-off-by:

No reason to verify channel switch request in driver, it can simply be forwarded to wireless device. Device can perform required checks and return appropriate error code, and driver may not even have information on current operational channel. Signed-off-by:

This makes no sense because real operational channel is choosen based on AP operation, not on what STA is configured to. Signed-off-by:

Do not try to cache current operational channel info in driver, this is a potential source of synchronization issues + driver does not really need that info. Introduce GET_CHANNEL command and process it appropriately. Signed-off-by:

This will allow to use qlink channel width values to specify BW setting corresponding to enum nl80211_chan_width. Current user is converted to apply BIT() macro manually to each individual qlink_channel_width enumeration value. Signed-off-by:

Application will keep track of whether MAC address randomization is enabled or not during scan. But at present driver is storing 'random_mac' in mwifiex_private which implies even after scan is done driver has some reference to the earlier 'scan request'. To avoid this, make use of 'mac_addr' variable in 'scan_request' to store 'random_mac'. This structure will be freed by cfg80211 once scan is done. Signed-off-by:

Driver sends a series of scan commands to firmware to serve a user scan request. If an intermediate scan command fails, driver aborts the scan but it is not being informed to cfg80211. This will cause issues in applications performing periodic scans. Fix this by informing scan abort. Signed-off-by:

In routine rtl92ee_set_fw_rsvdpagepkt(), the driver allocates an skb, but never calls rtl_cmd_send_packet(), which will free the buffer. All other rtlwifi drivers perform this operation correctly. This problem has been in the driver since it was included in the kernel. Fortunately, each firmware load only leaks 4 buffers, which likely explains why it has not previously been detected.

The u8 char array ret is not being initialized and elements outside the range start to end contain just garbage values from the stack. This results in a later scan of the array to read potentially uninitialized values. Fix this by initializing the array to zero. This seems to have been an issue since the very first commit.
