2020-12-11iwlwifi: mvm: Fix fall-through warnings for ClangGustavo A. R. Silva
In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by explicitly using the fallthrough pseudo-keyword as a replacement for a number of "fall through" markings. Notice that Clang doesn't recognize "fall through" comments as implicit fall-through. Link: https://github.com/KSPP/linux/issues/115 Signed-off-by: Gustavo A. R.

2020-12-10iwlwifi: mvm: disconnect if channel switch delay is too longJohannes Berg

2020-12-10iwlwifi: mvm: fix a race in CSA that caused assert 0x3420Sara Sharon
When we get a channel switch with a very long quiet period, we schedule a work to disconnect after a while. This work runs in background. In the meanwhile, we keep getting beacons and sending FW modify command for each. This has a potential race, where we modify the CSA after we aborted it. Protect the flow by setting csa_failed to true in case we abort, and check it before sending the modify command. This required a modification to the way we treat csa_failed in iwl_mvm_post_channel_switch: 1. The variable isn't being reset anymore, so we can still look at it in iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when starting a new CSA. 2. There is no more early return in case of csa_failed. This is fine, since before this patch csa_failed was set only for GO, and for GO the function is only resetting the power settings, which we want to restore even in case of failure.

We're currently doing accounting on the queue sync with an atomic variable that counts down the number of remaining notifications that we still need.

2020-12-10iwlwifi: mvm: clear up iwl_mvm_notify_rx_queue() argument typeJohannes Berg
The argument type to iwl_mvm_notify_rx_queue() is currently just a u8 *, but that's misleading because we actually need the inner data to be of type struct iwl_mvm_internal_rxq_notif, because we interpret it when we get it back from the device (to check the sync bool and possibly the cookie.) Therefore, clear up any potential confusion and require that the data passed is of type struct iwl_mvm_internal_rxq_notif *. Also, while at it, rename the "count" to "notif_size" as "count" doesn't really clearly say what it's counting.

2020-10-01iwlwifi: mvm: Add FTM initiator RTT smoothing logicIlan Peer
The overcome instabilities in the RTT results add smoothing logic to the reported results. In short, the smoothing logic tracks the RTT average of each responder for a period of time, and in case a new RTT results is found to be a spur, the tracked RTT average is reported instead of the current RTT measurement. Smooth logic debug configuration using iwl-dbg-cfg.ini: - MVM_FTM_INITIATOR_ENABLE_SMOOTH: Set to 1 to enable smoothing logic (default=0). - MVM_FTM_INITIATOR_SMOOTH_ALPHA: A value between 0 - 100, defining the weight of the current RTT results vs. the RTT average tracked based on the previous results. A value of 100 means use only the current RTT results. - MVM_FTM_INITIATOR_SMOOTH_AGE_SEC: The maximal time in seconds in which the RTT average tracked based on previous results is considered valid. - MVM_FTM_INITIATOR_SMOOTH_UNDERSHOOT: if the current RTT is positive and below the RTT average by at least this value, report the average RTT instead of the current one. In units of picoseconds. - MVM_FTM_INITIATOR_SMOOTH_OVERSHOOT: if the current RTT is positive and above the RTT average by at least this value, report the average RTT instead of the current one.

The FW changed the maximum number of scan offload profiles to 8 in new APIs. Support it by changing the scan_offload_profile_cfg struct to be more dynamic, so we can reuse most of the code and only change size of the profiles array.

2020-02-03iwlwifi: mvm: fix TDLS discovery with the new firmware APIEmmanuel Grumbach
I changed the API for asking for a session protection but I omitted the TDLS flows. Fix that now. Note that for the TDLS flow, we need to block until the session protection actually starts, so add this option to iwl_mvm_schedule_session_protection. This patch fixes a firmware assert in the TDLS flow since the old TIME_EVENT_CMD is not supported anymore by newer firwmare versions.

2020-02-03iwlwifi: mvm: Check the sta is not NULL in iwl_mvm_cfg_he_sta()Andrei Otcheretianski
Fix a kernel panic by checking that the sta is not NULL. This could happen during a reconfig flow, as mac80211 moves the sta between all the states without really checking if the previous state was successfully set. So, if for some reason we failed to add back the station, subsequent calls to sta_state() callback will be done when the station is NULL. This would result in a following panic: BUG: unable to handle kernel NULL pointer dereference at 0000000000000040 IP: iwl_mvm_cfg_he_sta+0xfc/0x690 [iwlmvm] [..] Call Trace: iwl_mvm_mac_sta_state+0x629/0x6f0 [iwlmvm] drv_sta_state+0xf4/0x950 [mac80211] ieee80211_reconfig+0xa12/0x2180 [mac80211] ieee80211_restart_work+0xbb/0xe0 [mac80211] process_one_work+0x1e2/0x610 worker_thread+0x4d/0x3e0 [..] Signed-off-by: Andrei Otcheretianski <andrei.otcheretianski@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-12-23iwlwifi: mvm: report TX rate to mac80211 directly for RS offloadJohannes Berg
If we have offloaded rate scaling, which is always true for those devices supporting HE, then report the TX rate directly from the data the firmware gives us, instead of only passing it to mac80211 on frame status only and for it to track it. First of all, this makes us always report the last good rate that the rate scaling algorithm picked, which is better than reporting the last rate for any frame since management frames etc. are sent with very low rates and could interfere. Additionally, this allows us to properly report HE rates, though in case there's a lot of trigger-based traffic, we don't get any choice in the rates and don't report that properly right now.

2019-11-15iwlwifi: mvm: don't skip mgmt tid when flushing all tidsHaim Dreyfuss
There are various of flows which require tids flushing (disconnection, suspend, etc...). Currently, when the driver instructs the FW to flush he masks all the data tids(0-7). However, the driver doesn't set the management tid (#15) which cause the FW not to flush it. When the FW tries to remove the mgmt queue he throws an assert since it is not an empty queue. instead of just set only the data tids set everything and let the FW ignore the invalid tids.

2019-10-09iwlwifi: mvm: fix race in sync rx queue notificationNaftali Goldstein
Consider the following flow: 1. Driver starts to sync the rx queues due to a delba. mvm->queue_sync_cookie=1. This rx-queues-sync is synchronous, so it doesn't increment the cookie until all rx queues handle the notification from FW. 2. During this time, driver starts to sync rx queues due to nssn sync required. The cookie's value is still 1, but it doesn't matter since this rx-queue-sync is non-synchronous so in the notification handler the cookie is ignored. What _does_ matter is that this flow increments the cookie to 2 immediately. Remember though that the FW won't start servicing this command until it's done with the previous one. 3. FW is still handling the first command, so it sends a notification with internal_notif->sync=1, and internal_notif->cookie=0, which triggers a WARN_ONCE. The solution for this race is to only use the mvm->queue_sync_cookie in case of a synchronous sync-rx-queues. This way in step 2 the cookie's value won't change so we avoid the WARN. The commit in the "fixes" field is the first commit to introduce non-synchronous sending of this command to FW.

Use cancel_delayed_work_sync on the dump workers only in case of unloading the op mode. In any other case use iwl_fw_flush_dumps or iwl_fw_dbg_stop_sync (depends if the op mode mutex is held or not).
