The statistics are currently only half-heartedly locked against concurrent reading & modification so introduce a lock to really protect them. Signed-off-by:

Now that the transport has its own locking, there's no need to have the sta_lock in the shared data. Also, it can be a BH lock as it's not used from IRQ handlers. Signed-off-by:

Instead of (ab)using the sta_lock, make the transport layer lock its own TX queue data structures with a lock per queue. This also unifies with the cmd queue lock. Signed-off-by:

In the powersave related functions we only need to set a few parameters for the station command and can otherwise leave it blank -- there's no need to copy it from the database. This allows us to not use the sta lock here. Signed-off-by:

When we TX, we hold the sta_lock for a long time, a lot of which isn't needed. Reduce the time we hold the lock. Note that this doesn't really change anything as the code is already under the other spinlock, but it makes the code easier to read. Signed-off-by:

We should be doing a shift (1 << FLAG_RADIO_DOWN) here before testing the flag. As luck would have it, this test works almost correctly. The current code tests for FLAG_RADIO_OFF instead of FLAG_RADIO_DOWN. #define FLAG_RADIO_OFF 0 /* User disabling of MAC */ #define FLAG_RADIO_DOWN 1 /* ifup/ifdown disabling of MAC */ Signed-off-by:

If we only monitor while associated, the following can happen: - we're associated, and the queue stuck check runs, setting the queue "touch" time to X - we disassociate, stopping the monitoring, which leaves the time set to X - almost 2s later, we associate, and enqueue a frame - before the frame is transmitted, we monitor for stuck queues, and find the time set to X, although it is now later than X + 2000ms, so we decide that the queue is stuck and erroneously restart the device It happens more with P2P because there we can go between associated/unassociated frequently.

Driver rtl8192ce when used with the RTL8188CE device would start at about 20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the symptoms is that the AP would need to retransmit each packet 4 of 5 times before the driver would acknowledge it. Recovery is possible only by unloading and reloading the driver. This problem was reported at https://bugzilla.redhat.com/show_bug.cgi?id=770207. The problem is due to a missing update of the gain setting. Signed-off-by:

This patch allows the possibility of having the mesh point and AP to be operated simultaneously in one single radio. Previously, mesh point fails to generate the mesh beacon if virtual AP is created for the same radio. Signed-off-by:

As indicated in [1] on netdev mailing list drivers should not block on the init_module() syscall. This patch defers the actual driver registration to a workqueue so the init_module() syscall can complete without delay. [1] http://article.gmane.org/gmane.linux.network/217729/Reviewed-by:

The usb code defines a structure for counting statistics. However, it should use the statistics entry provided in brcmf_bus as that is exposed to the net_device. The usb private statistics counter only remains with counters for control packets between driver and usb device. Reviewed-by:

When driver rtl8192cu is used with the debug level set to 3 or greater, the result is "sleeping function called from invalid context" due to an rcu_read_lock() call in the DM refresh routine in driver rtl8192c. This lock is not necessary as the USB driver does not use the struct being protected, thus the lock is set only when a PCI interface is active. This bug is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42775. Reported-by:

In usb.c, routine _rtl_usb_init_sw() always returns 0, and rtl_usb_probe() never checks the returned value. Thus we can change _rtl_usb_init_sw() to a void routine. In addition, remove the underscore at the beginning of the name of the routine. Signed-off-by:

In the unlikely event of a misread of the USB end point count, the driver generates a divide fault. To prevent this, add a check of the value returned by _rtl_usb_init(). In addition, add some logging to indicate why the condition occurred. Signed-off-by:

When associating and particularly when disassociating there's no need to notify the driver about changes with multiple calls to bss_info_changed, we should combine the QoS enabling/disabling into the same call as otherwise the driver could get confused about QoS suddenly getting disabled while connected.

There's no need to hardcode a subset of the radiotap header for cooked monitor receive, we can just reuse the normal monitor mode radiotap code. This simplifies the code and extends the information available on cooked monitor interfaces. Signed-off-by:

This patch adds an attribute, NL80211_ATTR_INACTIVITY_TIMEOUT, to set the inactivity timeout which can be used to remove the station in AP mode. This can be passed in NL80211_CMD_START_AP and used by the drivers which have AP MLME in firmware but don't support get_station() properly. To disable inactivity timer in userspace, wpa_s for example, there is a new flag, NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags through which drivers can register their capability to use the inactivity timeout to free the stations.

RANN, PREP and PERR propagation should happen only if the dot11MeshForwarding is true. Besides, data frame should not be forwarded if dot11MeshForwarding is false. This redundant checking is necessary to avoid the broadcasted ARP breaking the non-forwarding rule. Signed-off-by:

For A-MPDU rx it makes sense to only process the signal strength once per aggregate instead of once per subframe. Additonally, some hardware (e.g. Atheros) only provides valid signal strength information for the last subframe. Signed-off-by:

Several MAC address comparison functions assume 16 bit alignment for pointers passed to them. Since the addition of the control_port field, alignment for the IBSS bssid was off by one, causing a severe performance hit on architectures without efficient unaligned access (e.g. MIPS). Signed-off-by:

In mwifiex_drv_change_adhoc_chan() we pass channel to mwifiex_bss_ioctl_ibss_channel() which sets the high 16 bits. This works on little endian systems but not on big endian ones. I've changed mwifiex_drv_change_adhoc_chan() to use a 16 bit variable. This matches the other functions in the file. I considered changing mwifiex_change_adhoc_chan() as well but it turns out that the function isn't implemented so I just removed the definition. Signed-off-by:

'beacon_period' in 'struct ndis_80211_conf' is __le32 instead of __le16 so le32_to_cpu must be used instead of le16_to_cpu. Also correct 'beacon_interval' variables used for passing this value forward from u16 to u32 and rename those variables 'beacon_period' This is to avoid confusion because 'beacon_interval' is defined as __le16 at other structure, 'struct ndis_80211_fixed_ies'.
