2024-08-27wifi: iwlwifi: mvm: avoid NULL pointer dereferenceMiri Korenblit
iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta pointer is not NULL. It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is dereferencing the ieee80211_sta pointer. If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL pointer. Fix this by checking the sta pointer before retrieving the mvmsta from it. If sta is not NULL, then mvmsta isn't either.

2024-08-27wifi: iwlwifi: mvm: drop wrong STA selection in TXJohannes Berg
This shouldn't happen at all, since in station mode all MMPDUs go through the TXQ for the STA, and not this function. There may or may not be a race in mac80211 through which this might happen for some frames while a station is being added, but in that case we can also just drop the frame and pretend the STA didn't exist yet. Also, the code is simply wrong since it uses deflink, and it's not easy to fix it since the mvmvif->ap_sta pointer cannot be used without the mutex, and perhaps the right link might not even be known. Just drop the frame at that point instead of trying to fix it up.

2024-08-27wifi: iwlwifi: mvm: Offload RLC/SMPS functionality to firmwareDaniel Gabay
Currently, the driver handles SMPS decisions by tracking AP capabilities, BT coexistence changes, sending necessary SMPS frames to the AP, and updating firmware with RX chain info using the RLC_CONFIG_CMD. Starting with version 3 of the RLC_CONFIG_CMD, the firmware takes over this responsibility. It now tracks SMPS, sends frames, and configures the RLC. In this patch: 1. Stop sending RLC_CONFIG_CMD when firmware supports RLC offload (version 3), as rlc.rx_chain_info is not needed by firmware, and no other field in the cmd is used. 2. Prevent the driver from forwarding any SMPS requests to mac80211, i.e., the driver should not transmit SMPS frames to the AP as firmware handles that. 3. Set NL80211_FEATURE_DYNAMIC_SMPS and NL80211_FEATURE_STATIC_SMPS conditionally based on RLC version.

2024-08-27wifi: iwlwifi: mvm: Fix a race in scan abort flowIlan Peer
When the upper layer requests to cancel an ongoing scan, a race is possible in which by the time the driver starts to handle the upper layers scan cancel flow, the FW already completed handling the scan request and the driver received the scan complete notification but still did not handle the notification. In such a case the FW will simply ignore the scan abort request coming from the driver, no notification would arrive from the FW and the entire abort flow would be considered a failure. To better handle this, check the status code returned by the FW for the scan abort command. In case the status indicates that no scan was aborted, complete the scan abort flow with success, i.e., the scan was aborted, as the flow is expected to consume the scan complete notification.

2024-08-27wifi: iwlwifi: clear trans->state earlier upon errorEmmanuel Grumbach
When the firmware crashes, we first told the op_mode and only then, changed the transport's state. This is a problem if the op_mode's nic_error() handler needs to send a host command: it'll see that the transport's state still reflects that the firmware is alive. Today, this has no consequences since we set the STATUS_FW_ERROR bit and that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording looks at this bit to know not to send a host command for example. To fix the hibernation, we needed to reset the firmware without having an error and checking STATUS_FW_ERROR to see whether the firmware is alive will no longer hold, so this change is necessary as well. Change the flow a bit. Change trans->state before calling the op_mode's nic_error() method and check trans->state instead of STATUS_FW_ERROR. This will keep the current behavior of iwl_fw_dbg_stop_restart_recording upon firmware error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not alive.

2024-08-26wifi: iwlwifi: mvm: don't wait for tx queues if firmware is deadEmmanuel Grumbach
There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was recently converted from just a message), that can be hit if we wait for TX queues to become empty after firmware died.

MLO internal scan may include 6 GHz channels. Since the 6 GHz scan indication is not set, the channel flags are set incorrectly, which leads to a firmware assert. Since the MLO scan may include 6 GHz and non 6 GHz channels in one request, add support for non-PSC 6 GHz channels (PSC channels are already supported) when the 6 GHz indication is not set.

2024-08-26wifi: iwlwifi: mvm: fix hibernationEmmanuel Grumbach
Fast resume is a feature that was recently introduced to speed up the resume time. It basically keeps the firmware alive while the system is suspended and that avoids starting again the whole device. This flow can't work for hibernation, since when the system boots, before the frozen image is loaded, the kernel may touch the device. As a result, we can't assume the device is in the exact same state as before the hibernation. Detect that we are resuming from hibernation through the PCI device and forbid the fast resume flow. We also need to shut down the device cleanly when that happens. In addition, in case the device is power gated during S3, we won't be able to keep the device alive. Detect this situation with BE200 at least with the help of the CSR_FUNC_SCRATCH register and reset the device upon resume if it was power gated during S3.

2024-08-13wifi: iwlwifi: correctly lookup DMA address in SG tableBenjamin Berg
The code to lookup the scatter gather table entry assumed that it was possible to use sg_virt() in order to lookup the DMA address in a mapped scatter gather table. However, this assumption is incorrect as the DMA mapping code may merge multiple entries into one. In that case, the DMA address space may have e.g. two consecutive pages which is correctly represented by the scatter gather list entry, however the virtual addresses for these two pages may differ and the relationship cannot be resolved anymore. Avoid this problem entirely by working with the offset into the mapped area instead of using virtual addresses. With that we only use the DMA length and DMA address from the scatter gather list entries. The underlying DMA/IOMMU code is therefore free to merge two entries into one even if the virtual addresses space for the area is not continuous.

2024-07-18thermal: core: Allow thermal zones to tell the core to ignore themRafael J. Wysocki
The iwlwifi wireless driver registers a thermal zone that is only needed when the network interface handled by it is up and it wants that thermal zone to be effectively ignored by the core otherwise. Before commit a8a261774466 ("thermal: core: Call monitor_thermal_zone() if zone temperature is invalid") that could be achieved by returning an error code from the thermal zone's .get_temp() callback because the core did not really handle errors returned by it almost at all. However, commit a8a261774466 made the core attempt to recover from the situation in which the temperature of a thermal zone cannot be determined due to errors returned by its .get_temp() and is always invalid from the core's perspective. That was done because there are thermal zones in which .get_temp() returns errors to start with due to some difficulties related to the initialization ordering, but then it will start to produce valid temperature values at one point. Unfortunately, the simple approach taken by commit a8a261774466, which is to poll the thermal zone periodically until its .get_temp() callback starts to return valid temperature values, is at odds with the special thermal zone in iwlwifi in which .get_temp() may always return an error because its network interface may always be down. If that happens, every attempt to invoke the thermal zone's .get_temp() callback resulting in an error causes the thermal core to print a dev_warn() message to the kernel log which is super-noisy. To address this problem, make the core handle the case in which .get_temp() returns 0, but the temperature value returned by it is not actually valid, in a special way. Namely, make the core completely ignore the invalid temperature value coming from .get_temp() in that case, which requires folding in update_temperature() into its caller and a few related changes. On the iwlwifi side, modify iwl_mvm_tzone_get_temp() to return 0 and put THERMAL_TEMP_INVALID into the temperature return memory location instead of returning an error when the firmware is not running or it is not of the right type. Also, to clearly separate the handling of invalid temperature values from the thermal zone initialization, introduce a special THERMAL_TEMP_INIT value specifically for the latter purpose.

2024-07-12thermal: trip: Pass trip pointer to .set_trip_temp() thermal zone callbackRafael J. Wysocki
Out of several drivers implementing the .set_trip_temp() thermal zone operation, three don't actually use the trip ID argument passed to it, two call __thermal_zone_get_trip() to get a struct thermal_trip corresponding to the given trip ID, and the other use the trip ID as an index into their own data structures with the assumption that it will always match the ordering of entries in the trips table passed to the core during thermal zone registration, which is fragile and not really guaranteed. Even though the trip IDs used by the core are in fact their indices in the trips table passed to it by the thermal zone creator, that is purely a matter of convenience and should not be relied on for correctness. For this reason, modify trip_point_temp_store() to pass a (const) trip pointer to .set_trip_temp() and adjust the drivers implementing it accordingly. This helps to simplify the drivers invoking __thermal_zone_get_trip() from their .set_trip_temp() callback functions because they will not need to do it now and the other drivers can store their internal trip indices in the priv field in struct thermal_trip and their .set_trip_temp() callback functions can get those indices from there. The intel_quark_dts thermal driver can instead use the trip type to determine the requisite trip index. Signed-off-by: Rafael J.
