Introduce manual FW recovery mode. It is activated if module parameter @no_fw_recovery set to true. May be changed at runtime. Recovery information provided by new "recovery" debugfs file. It prints: mode = [auto|manual] state = [idle|pending|running] In manual mode, after FW error, recovery won't start automatically. Instead, after notification to user space, recovery waits in "pending" state, as indicated by the "recovery" debugfs file. User space tools may perform data collection and allow to continue recovery by writing "run" to the "recovery" debugfs file. Alternatively, recovery pending may be canceled by stopping network interface i.e. 'ifconfig wlan0 down' Signed-off-by:

We did not return error if multicast packet transmit failed. This might not be desired so return error also in this case. If there are multiple 6lowpan devices where the multicast packet is sent, then return error even if sending to only one of them fails. Signed-off-by:

The L2CAP connection's channel list lock (conn->chan_lock) must never be taken while already holding a channel lock (chan->lock) in order to avoid lock-inversion and lockdep warnings. So far the l2cap_chan_connect function has acquired the chan->lock early in the function and then later called l2cap_chan_add(conn, chan) which will try to take the conn->chan_lock. This violates the correct order of taking the locks and may lead to the following type of lockdep warnings: -> #1 (&conn->chan_lock){+.+...}: [<c109324d>] lock_acquire+0x9d/0x140 [<c188459c>] mutex_lock_nested+0x6c/0x420 [<d0aab48e>] l2cap_chan_add+0x1e/0x40 [bluetooth] [<d0aac618>] l2cap_chan_connect+0x348/0x8f0 [bluetooth] [<d0cc9a91>] lowpan_control_write+0x221/0x2d0 [bluetooth_6lowpan] -> #0 (&chan->lock){+.+.+.}: [<c10928d8>] __lock_acquire+0x1a18/0x1d20 [<c109324d>] lock_acquire+0x9d/0x140 [<c188459c>] mutex_lock_nested+0x6c/0x420 [<d0ab05fd>] l2cap_connect_cfm+0x1dd/0x3f0 [bluetooth] [<d0a909c4>] hci_le_meta_evt+0x11a4/0x1260 [bluetooth] [<d0a910eb>] hci_event_packet+0x3ab/0x3120 [bluetooth] [<d0a7cb08>] hci_rx_work+0x208/0x4a0 [bluetooth] CPU0 CPU1 ---- ---- lock(&conn->chan_lock); lock(&chan->lock); lock(&conn->chan_lock); lock(&chan->lock); Before calling l2cap_chan_add() the channel is not part of the conn->chan_l list, and can therefore only be accessed by the L2CAP user (such as l2cap_sock.c). We can therefore assume that it is the responsibility of the user to handle mutual exclusion until this point (which we can see is already true in l2cap_sock.c by it in many places touching chan members without holding chan->lock). Since the hci_conn and by exctension l2cap_conn creation in the l2cap_chan_connect() function depend on chan details we cannot simply add a mutex_lock(&conn->chan_lock) in the beginning of the function (since the conn object doesn't yet exist there). What we can do however is move the chan->lock taking later into the function where we already have the conn object and can that way take conn->chan_lock first. This patch implements the above strategy and does some other necessary changes such as using __l2cap_chan_add() which assumes conn->chan_lock is held, as well as adding a second needed label so the unlocking happens as it should.

When mwifiex device becomes GO, unicast traffic between client1 and GO stops when client2 connects to GO. Reason behind this was PTK getting overwritten by key_material command for client2 as it did not have client mac address. So, client1 can no more decode GO's ping packets though it responds to its broadcast packets. This patch adds case to check for BSS_ROLE instead of bss_type to set client mac address while configuring keys when device becomes GO. Signed-off-by:

chan_lock is not required for checking if we are in the middle of a HW reset, so do it early. This also removes the small window where the lock is dropped and reacquired. Signed-off-by:

On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL register changed. This currently breaks at least 5/10 MHz operation. AR933x uses the old layout. It might also have been causing other stability issues because of the different location of the PLL_BYPASS bit which needs to be set during PLL clock initialization. This patch also removes more instances of hardcoded register values in favor of properly computed ones with the PLL_BYPASS bit added. Reported-by:

The cycpwr_thr1 value needs to be lower on the extension channel than on the control channel, similar to how the register settings are programmed in the initvals. Also drop the unnecessary check for HT40 - this register can always be written. This patch has been reported to improve HT40 stability and throughput in some environments. Signed-off-by:

A soft lockup was observed on ARM multicore platform while UDP RX iperf was running on station. Reason for this is delay_main_task was not taken into consideration while jumping to process_start. Now if delay_main_task is true, we would exit mwifiex_main_process instead of going to process_start again. This ensure other process is scheduled on this CPU and soft lockup is avoided.

On AR934x rev 3, settin the ad-hoc flag completely messes up hardware state - beacons get stuck, almost no packets make it out, hardware is constantly reset. When leaving out that flag and setting up the hw like in AP mode, TSF timers won't be automatically synced, but at least the rest works. AR934x rev 2 and older are not affected by this bug Signed-off-by:

This patch updates the driver to match the latest Realtek release, and it is an important step in getting the internal code source at Realtek to match the code in the kernel. The primary reason for this is to make it easier for Realtek to maintain the kernel source without requiring an intermediate like me. In this process of merging the two source repositories, there are a lot of changes in both, and this commit is rather large. Signed-off-by:

This driver was entered into staging a few cycles ago because there was not time to integrate the Realtek version into the support routines in the kernel. Now that there is an effort to converg the code base from Linux and the Realtek repo, it is time to move this driver. In addition, all the updates included in the 06/28/2014 version of the Realtek drivers are included here. With this change, it will be necessary to delete the staging driver. That will be handled in a separate patch. As it impacts the staging tree, such a patch is sent to a different destination. Signed-off-by:
