2018-03-13mt7601u: let mac80211 validate rx CCMP PNLorenzo Bianconi
Apparently the hardware does not perform CCMP PN validation so let mac80211 take care of possible replay attacks in sw. Moreover indicate ICV and MIC had been stripped setting corresponding bits in ieee80211_rx_status. The fix has been validated using 4.2.1 and 4.1.3 tests from the WiFi Alliance vulnerability detection tool.

2018-02-28mt7601u: make write with mask access atomicLorenzo Bianconi
Introduce __mt7601u_rr and __mt7601u_vendor_single_wr routines in order to make mt7601u_rmw and mt7601u_rmc atomic. This patch does not fix a reported issue but makes the usb access more robust to concurrent operations on the same register since it is theoretically possible that read and write accesses of mt7601u_rmw/mt7601u_rmc can be interleaved with a different write operation on the same register. Moreover using __mt7601u_rr and __mt7601u_vendor_single_wr in mt7601u_rmw/mt7601u_rmc allows to grab vendor_req_mutex mutex once instead of twice Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Jakub Kicinski <kubakici@wp.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-02-27ssb: return boolean instead of integer in ssb_dma_translation_special_bitGustavo A. R. Silva
Return statements in functions returning bool should use true/false instead of 1/0. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <garsilva@embeddedor.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-02-27bcma: Replace mdelay with usleep_range in bcma_pmu_resources_initJia-Ju Bai
After checking all possible call chains to bcma_pmu_resources_init() here, my tool finds that this function is never called in atomic context, namely never in an interrupt handler or holding a spinlock. Thus mdelay can be replaced with usleep_range to avoid busy wait. This is found by a static analysis tool named DCNS written by myself.

2018-02-27wl1251: Set generated MAC address back to NVS dataPali Rohár
In case there is no valid MAC address kernel generates random one. This patch propagate this generated MAC address back to NVS data which will be uploaded to wl1251 chip. So HW would have same MAC address as linux kernel uses. This should not change any functionality, but it is better to tell wl1251 correct mac address since beginning of chip usage.

2018-02-27wl1251: Parse and use MAC address from supplied NVS dataPali Rohár
This patch implements parsing MAC address from NVS data which are sent to wl1251 chip. Calibration NVS data could contain valid MAC address and it will be used instead of randomly generated one. This patch also moves code for requesting NVS data from userspace to driver initialization code to make sure that NVS data will be there at time when permanent MAC address is needed. Calibration NVS data for wl1251 are device specific. Every device with wl1251 chip should have been calibrated in factory and needs to provide own calibration data. Default example file wl1251-nvs.bin, found in linux-firmware repository, contains MAC address 00:00:20:07:03:09. So this MAC address is marked as invalid as it is not real device specific address, just example one. Format of calibration NVS data can be found at: http://notaz.gp2x.de/misc/pnd/wl1251/nvs_map.txt Signed-off-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-02-27wl1251: Generate random MAC address only if driver does not have validPali Rohár
Before this patch, driver generated random MAC address every time it was initialized. After that random MAC address could be overwritten with fixed one, if provided. This patch changes order. First it tries to read fixed MAC address and if it fails then driver generates random MAC address.

From Thomas Falcon. 10) Fix TCP checksum on LRO buffers in mlx5e, from Gal Pressman. 11) When we are dumping filters in cls_api, the output SKB is empty, and the filter we are dumping is too large for the space in the SKB, we should return -EMSGSIZE like other netlink dump operations do. Otherwise userland has no signal that is needs to increase the size of its read buffer. From Roman Kapl. 12) Several XDP fixes for virtio_net, from Jesper Dangaard Brouer. 13) Module refcount leak in netlink when a dump start fails, from Jason Donenfeld. 14) Handle sub-optimal GSO sizes better in TCP BBR congestion control, from Eric Dumazet. 15) Releasing bpf per-cpu arraymaps can take a long time, add a condtional scheduling point.
