Instead of using 4KB packet buffer for data transfer, new chipset have more device memory. This patch try to aggregation packets in an 16KB buffer. In this way, totally usb transaction cost will be reduced. Thoughput test on usb 2.0 show both TCP TX and UPD TX promote ~40M, from ~240M to ~280M. This feature is default disabled, and can be enabled by module parameter, like: insmod mwifiex.ko aggr_ctrl=1 Signed-off-by:

we have observed host system hang when device firmware crash, stack trace show it was an use-after-free case: previous submitted urb will be holding in usbcore, and given back to device driver when device disconnected, while the urb have been freed in usb device disconnect handler. This patch kill the holding urb before free its memory. Signed-off-by:

This patch adds support for new FullMAC WiFi driver for Quantenna QSR10G chipsets. QSR10G (aka Pearl) is Quantenna's 8x8, 160M, 11ac offering. QSR10G supports 2 simultaneous WMACs - one 5G and one 2G. 5G WMAC supports 160M, 8x8 configuration. FW supports up to 8 concurrent virtual interfaces on each WMAC. Patch introduces 2 new drivers: - qtnfmac.ko for interfacing with kernel wireless core - qtnfmac_pearl_pcie.ko for interfacing with hardware over PCIe interface Signed-off-by:

When wifi is under concurrent mode, we can not distinguish if it is the real PS or just a fake one by sending null data, so we turn it off in case of miracast scenario. Signed-off-by:

The larger the bt a2dp bit pool is, the more time bt needs to receive them. If we do not adjust the wifi duration, the voice quality will be low. Hence we reduce the time that wifi holds, to improve the a2dp service. If the bt is slave, it may receive a packet at any time, so we need to mark them as high priority packets in case of packet loss Signed-off-by:

With CONFIG_KASAN enabled and gcc-7, we get a warning about rather high stack usage (with a private patch set I have to turn on this warning, which I intend to get into the next kernel release): wireless/ralink/rt2x00/rt2800lib.c: In function 'rt2800_bw_filter_calibration': wireless/ralink/rt2x00/rt2800lib.c:7990:1: error: the frame size of 2144 bytes is larger than 1536 bytes [-Werror=frame-larger-than=] The problem is that KASAN inserts a redzone around each local variable that gets passed by reference, and the newly added function has a lot of them.

This prepares the driver for changing all the 'read' register accessors to return the value instead of passing it by reference. Since a lot of them are used in callbacks, this takes care of the callbacks first, adding a couple of helpers that will be removed again one at a time. Signed-off-by:

Using memcpy() from a string that is shorter than the length copied means the destination buffer is being filled with arbitrary data from the kernel rodata segment. Instead, redefine the stat strings to be ETH_GSTRING_LEN sizes, like other drivers. This lets us use a single memcpy that does not leak rodata contents. Additionally adjust indentation to keep checkpatch.pl happy. This was found with the future CONFIG_FORTIFY_SOURCE feature. Cc: Daniel Micay <danielmicay@gmail.com> Signed-off-by:

iwlegacy firmware can crash when power save is configured. PS was allowed in "dbdac2b5 iwlegacy: properly enable power saving" with belive that user who enable PS is aware of that and can relate firmware crahes with PS. However some distributions seems to enable PS without user intervention, so warn about that. Signed-off-by:
