iwlwifi: pcie: fix DMA memory mapping / unmapping

2018-01-05T11:54:22Z

22000 devices (previously referenced as A000) can support short transmit queues. This means that we have less DMA descriptors (TFD) for those shorter queues. Previous devices must still have 256 TFDs for each queue even if those 256 TFDs point to fewer buffers. When I introduced support for the short queues for 22000 I broke older devices by assuming that they can also have less TFDs in their queues. This led to several problems: 1) the payload of the commands weren't unmapped properly which caused the SWIOTLB to complain at some point. 2) the hardware could get confused and we get hardware crashes.

iwlwifi: mvm: mark MIC stripped MPDUs

2017-12-05T14:23:30Z

When RADA is active, the hardware decrypts the packets and strips off the MIC as it is useless after decryption. Indicate that to mac80211. Cc: stable@vger.kernel.org # 4.13+ [this is needed for the 9000-series HW to work properly] Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho

iwlwifi: mvm: flush queue before deleting ROC

2017-12-05T14:23:29Z

Before deleting a time event (remain-on-channel instance), flush the queue so that frames cannot get stuck on it. We already flush the AUX STA queues, but a separate station is used for the P2P Device queue. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg Signed-off-by: Luca Coelho

Pull timer updates from Thomas Gleixner: - The final conversion of timer wheel timers to timer_setup(). A few manual conversions and a large coccinelle assisted sweep and the removal of the old initialization mechanisms and the related code. - Remove the now unused VSYSCALL update code - Fix permissions of /proc/timer_list.

iwlwifi: fix access to prph when transport is stopped

2017-11-25T15:12:56Z

When getting HW rfkill we get stop_device being called from two paths. One path is the IRQ calling stop device, and updating op mode and stack. As a result, cfg80211 is running rfkill sync work that shuts down all devices (second path). In the second path, we eventually get to iwl_mvm_stop_device which calls iwl_fw_dump_conf_clear->iwl_fw_dbg_stop_recording, that access periphery registers. The device may be stopped at this point from the first path, which will result with a failure to access those registers. Simply checking for the trans status is insufficient, since the race will still exist, only minimized. Instead, move the stop from iwl_fw_dump_conf_clear (which is getting called only from stop path) to the transport stop device function, where the access is always safe. This has the added value, of actually stopping dbgc before stopping device even when the stop is initiated from the transport.

iwlwifi: mvm: fix packet injection

2017-11-25T15:06:42Z

We need to have a station and a queue for the monitor interface to be able to inject traffic. We used to have this traffic routed to the auxiliary queue, but this queue isn't scheduled for the station we had linked to the monitor vif. Allocate a new queue, link it to the monitor vif's station and make that queue use the BE fifo.
