Instead of leaving the buffer without skb and breaking out of the loop (which could leak the rx buffer), use the common error path. Signed-off-by:

The functions in the rt2x00mmio module has been moved from the rt2x00pci module. Each function uses the rt2x00pci prefix which is a bit confusing. Use the r2x000mmio prefix for each function to make it consistent with the module name. The renamed functions are used by several modules, and updating the names in all of them would result in a big patch. In order to keep the patch simple, add compatibility defines for the old function names. This allows to update the names in each module separately. After each module is updated, the defines can be removed. The patch contains no functional changes. Signed-off-by:

In brcmf_rx_frames() the call to brcmf_fweh_process_skb() could change the ifidx using information in the event data. This is only different to the BDC ifidx for IF ADD event. However, the creation of the new interface is deferred to event worker so it does not exist. After brcmf_fweh_process_skb() it is only used to set statistics. Reviewed-by:

The function brcmf_p2p_notify_action_frame_rx() the wireless_dev is needed to pass the action frame to cfg80211. The wireless_dev is held in brcmf_cfg80211_vif object. Use that instead of the ieee80211_ptr in net_device as P2P_DEVICE interface does not have a net_device associated with it. Reviewed-by:

The current driver code creates a P2P_DEVICE through a module parameter. This device has a dummy netdevice which is not how this interface type is intended. This patch add proper support for the P2P_DEVICE interface type. This requires a wpa_supplicant with such support as well. Reviewed-by:

Not locking ra_list when dequeuing packets creates race conditions. When adding a packet 'tx_pkts_queued' is modified before setting highest_priority_queue. If in-between the main loop starts, it will see a packet queued (tx_pkts_queued > 0) but will not find it, since max prio is not set yet. Depending on the scheduling, the thread trying to add the packet could complete and restore the situation. But this is not something to rely on. Another race condition exists, if a new packet, exceeding current max prio is added. If concurrently a packet is dequeued, the newly set max prio will be overwritten with the value of the dequeued packet. This can occur, because selecting a packet and modifying the max prio is not atomic. The result in an infinite loop unless, a new packet is added that has at least the priority of the hidden packet. Same applies to bss_prio_tbl. Forward iteration is no proper lock-free technique and provides no protection from calls to list_del. Although BSS are currently not added/removed dynamically, this must not be the case in the future. Hence always hold proper locks when accessing those lists. Signed-off-by:

Using NO_PKT_PRIO_TID and tx_pkts_queued to check for an empty state, can lead to a contradictory state, resulting in an infinite loop. Currently queueing and dequeuing of packets is not synchronized, and can happen concurrently. While tx_pkts_queued is incremented when adding a packet, max prio is set to NO_PKT when the WMM list is empty. If a packet is added right after the check for empty, but before setting max prio to NO_PKT, that packet is trapped and creates an infinite loop. Because of the new packet, tx_pkts_queued is at least 1, indicating wmm lists are not empty. Opposing that max prio is NO_PKT, which means "skip this wmm queue, it has no packets". The infinite loop results, because the main loop checks the wmm lists for not empty via tx_pkts_queued, but for dequeing it uses max_prio to see if it can skip current list. This will never end, unless a new packet is added which will restore max prio to the level of the trapped packet. The solution here is to rely on tx_pkts_queued solely for checking wmm queue to be empty, and drop the NO_PKT define. It does not address the locking issue. Signed-off-by:

ra_list_spinlock is used to protect struct mwifiex_wmm_desc and embedded structures such as ra_list. tid_tbl_lock while more fine grained, is not used but in one function. That function is not called reentrantly. To protect ra_list from concurrent modification ra_list_spinlock must be held. Signed-off-by:

cmd_pending is increased in mwifiex_wait_queue_complete() and decreased in mwifiex_complete_cmd() currently. If there are two or more commands in the cmd_pending_q the main worker thread will pick up next command from cmd_pending_q automatically after finishing current command. As a result mwifiex_wait_queue_complete() will not be called because the command is alreay completed. This leads to a negative number in cmd_pending count. Fix it by increasing cmd_pending when a cmd is queued into cmd_pending_q and decreasing when that cmd is recycled. For scan commands we don't perform inc/dec operations until it's moved from scan_pending_q to cmd_pending_q. This covers both synchronous and asynchronous commands. Reported-by:
