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'.

If "offset" is negative then we can get past this check: if (offset > CONTROL_BUFFER_SIZE) Or if we pick a very high "req_ie_len" then we can get around the check: if (offset + req_ie_len > CONTROL_BUFFER_SIZE) I made "resp_ie_len" and "req_ie_len" unsigned. I don't know if it was intentional that they were signed in the original. Signed-off-by:

Mesh peer links are established only if average rssi of the peer candidate satisfies the threshold. This is not in 802.11s specification but was requested by David Fulgham, an open80211s user. This is a way to avoid marginal peer links with stations that are barely within range. This patch adds a new mesh configuration parameter, mesh_rssi_threshold. This feature is supported only for hardwares that report signal in dBm. Signed-off-by:

When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent firmware >= 478.104 it runs out of memory after a very short time in OpenWrt after doing an active scan or any thing else where packages are send. This was cased by a gpio misconfiguration, the firmware triggered the GPIO pins used for buttons on some devices and that caused an other driver (OpenWrt diag) listening for these buttons irqs to send many messages to the user space. This patch fixes the bug for my devices (Asus WL-520GU) and makes it work with firmware 666.2. Now the firmware just uses LED GPIO pin number 1 and not the button pins any more. This is the GPIO Pin layout used on my device, see [0]. GPIO pin layout: pin# name type 0 power led 1 wlan led 2 reset button 3 ses buttom This is the nvram configuration output of "nvram show |grep gpio" related nvram configuration: wl0gpio2=11 wl0gpio3=11 wl0gpio0=11 wl0gpio1=0x02 reset_gpio=2 [0]: https://dev.openwrt.org/browser/trunk/package/broadcom-diag/src/diag.cSigned-off-by:
