2025-01-13wifi: iwlwifi: mvm: improve/fix chanctx min_def use logicJohannes Berg
There are two cases in which the min_def isn't used: a) if FILS will be enabled b) if FTM responder is enabled Both of these apply to AP mode only, but for FILS we're not checking that right now. Change the code to iterate the interfaces and links using the channel context, and check for AP mode for both, not just for FTM responder. In the case of iwl_mvm_enable_fils() this might also fix an issue where FILS is enabled for an IBSS network that happens to be started on 6 GHz, though that's not very likely to be possible due to regulatory. However for RX OMI bandwidth reduction the driver needs to use the min_def in client mode as well, in order to actually reduce bandwidth when it requested that.

2025-01-13wifi: iwlwifi: implement product reset for TOP errorsJohannes Berg
The TOP is a shared (between BT and WiFi) hardware component, and if it has an error we need to reset the whole device, i.e. both BT and WiFi. This is achieved by calling a specific ACPI DSM (device-specific method) with the right arguments before doing a reset via the object referenced by _PRR. Since this is needed here, but a function reset will always do better than just re-enumerating the bus in case of errors, we can always try to at least do a function reset and do the full product reset only when needed for TOP errors. Also, for some Bz and Sc devices where BT is PCIe/IOSF as well, find the BT device and unbind that device as well so the BT driver can recover from the reset that's going to happen, rather than having to somehow detect that the device was reset. Also add - currently unused - the function reset mode, this is going to get used in the upcoming escalation model.

2025-01-13wifi: mac80211: add some support for RX OMI power savingJohannes Berg
In order to save power, it can be desirable to change the RX operating mode using OMI to reduce the bandwidth. As the handshake must be done in the HTC+ field, it cannot be done by mac80211 directly, so expose functions to the driver to request and finalize the necessary updates. Note that RX OMI really only changes what the peer (AP) will transmit to us, but in order to use it to actually save some power (by reducing the listen bandwidth) we also update rate scaling and then the channel context's mindef accordingly. The updates are split into two in order to sequence them correctly, when reducing bandwidth first reduce the rate scaling and thus TX, then send OMI, then reduce the listen bandwidth (chandef); when increasing bandwidth this is the other way around. This also requires tracking in different variables which part is applicable already.

2025-01-13wifi: iwlwifi: mvm: fix iwl_ssid_exist() checkMiri Korenblit
iwl_ssid_exist() seems to check if a given ssid/ssid_len already exists in a given array ssid_list. Correctly compare the ssid to the SSID of each array element (with a matching SSID length) to better remove duplicates. Signed-off-by: Bjoern A.

2025-01-13wifi: iwlwifi: mvm: remove unneeded NULL pointer checksEmmanuel Grumbach
Smatch reported that we dereference the data pointer to calculate the expected length before we check it's not NULL. While this is true (and hence needs to be fixed), this will never happen because the data pointer comes from struct iwl_rx_packet object which has the following layout: struct iwl_rx_packet { __le32 len_n_flags; struct iwl_cmd_header hdr; u8 data[]; } __packed; So, if the pointer to iwl_rx_packet is valid, data will be valid as well. Remove the NULL pointer check on 'data' to avoid confusing smatch. Also remove the check from similar functions in the same flow that were cargo cult copy-pasted.

2025-01-13wifi: iwlwifi: mvm: fix add stream vs. restart raceJohannes Berg
My recent restart related work has made this race more likely to happen and we've now noticed it, but it seems that it was always possible. The race is that the add stream work can be scheduled just before a restart is scheduled and then execute before the restart, accessing the device while it's doing the restart and not accessible. To fix this, check if the device is restarting and abort the work in that case. Reschedule it after the restart as well.

A caller of iwl_acpi_get_dsm_object must free the returned object. iwl_acpi_get_dsm_integer returns immediately without freeing it if the expected size is more than 8 bytes. Fix that. Note that with the current code this will never happen, since the caller of iwl_acpi_get_dsm_integer already checks that the expected size if either 1 or 4 bytes, so it can't exceed 8 bytes. While at it, print the DSM value instead of the return value, as this was the intention in the first place.
