2021-08-26iwlwifi: remove unused ACPI_WGDS_TABLE_SIZE definitionLuca Coelho1-2/+0
When we started supporting the new FW API for the geo profiles, we stopped using this definition, but left it there. Remove it now.

2021-08-26iwlwifi: support reading and storing EWRD revisions 1 and 2Luca Coelho2-11/+57
As an extension to the WRDS support for revisions 1 and 2, do the same for the EWRD tables. These tables have a very similar format to the WRDS table, so most of the code is similar.

2021-08-26iwlwifi: acpi: support reading and storing WRDS revision 1 and 2Luca Coelho2-25/+80
Change the SAR profile tables storage to revision 2 regardless of the revision we read from ACPI. Revision 2 is a superset of revision 1, which is in turn a superset of revision 0, so they can all be stored inside revision 2. Add support for reading and storing also revisions 1 and 2, whose only difference is the number of chains and number of sub-bands. So most of the code revolves around passing different chain and sub-band sizes. With this patch we still pass only revision 0 to the firmware, but that will be changed in a separate patch.

2021-08-26iwlwifi: remove ACPI_SAR_NUM_TABLES definitionLuca Coelho2-2/+2
This definition was only used to pass the size of the tables in the FW API to the iwl_sar_select_profile() function, but we should actually pass the definition from the FW API file. We don't have the concept of tables in the ACPI definition, so we can remove it.

2021-08-26iwlwifi: convert flat SAR profile table to a struct versionLuca Coelho2-15/+28
The SAR profiles have been stored in single-dimension arrays and the access has been done via a single index.

To prepare for that, convert the single-dimension array to a struct with substructures.

2021-08-26iwlwifi: mvm: silently drop encrypted frames for unknown stationAvraham Stern1-2/+2
When a station is removed, the driver-mac80211 station mapping is removed before the station is actually deleted from the FW.

2021-08-26iwlwifi: mvm: avoid static queue number aliasingJohannes Berg2-16/+38
When TVQM is enabled (iwl_mvm_has_new_tx_api() is true), then queue numbers are just sequentially assigned 0, 1, 2, ... Prior to TVQM, in DQA, there were some statically allocated queue numbers: * IWL_MVM_DQA_AUX_QUEUE == 1, * both IWL_MVM_DQA_INJECT_MONITOR_QUEUE and IWL_MVM_DQA_P2P_DEVICE_QUEUE == 2, and * IWL_MVM_DQA_AP_PROBE_RESP_QUEUE == 9. Now, these values are assigned to the members mvm->aux_queue, mvm->snif_queue, mvm->probe_queue and mvm->p2p_dev_queue by default. Normally, this doesn't really matter, and if TVQM is in fact available we override them to the real values after allocating a queue for use there. However, this allocation doesn't always happen. For example, for mvm->p2p_dev_queue (== 2) it only happens when the P2P Device interface is started, if any. If it's not started, the value in mvm->p2p_dev_queue remains 2. This wouldn't really matter all that much if it weren't for iwl_mvm_is_static_queue() which checks a queue number against one of those four static numbers. Now, if no P2P Device or monitor interface is added then queue 2 may be dynamically allocated, yet alias mvm->p2p_dev_queue or mvm->snif_queue, and thus iwl_mvm_is_static_queue() erroneously returns true for it. If it then gets full, all interface queues are stopped, instead of just backpressuring against the one TXQ that's really the only affected one. This clearly can lead to issues, as everything is stopped even if just a single TXQ filled its corresponding HW queue, if it happens to have an appropriate number (2 or 9, AUX is always reassigned.) Due to a mac80211 bug, this also led to a situation in which the queues remained stopped across a deauthentication and then attempts to connect to a new AP started failing, but that's fixed separately. Fix all of this by simply initializing the queue numbers to the invalid value until they're used, if TVQM is enabled, and also setting them back to that value when the queues are later freed again.

2021-08-26iwlwifi: mvm: set replay counter on key installJohannes Berg1-0/+53
When installing a (new) key, set the replay counter so that after FW restart the firmware has the correct value of the replay counters. This doesn't have a large effect - for frames that reach the driver, it will do a replay check, and when installing a new key, the counter is normally zero to start with (not for GTK though, if joining the BSS for the first time). Since this only affects frames handled entirely by the FW, and that's restricted to a few unicast management frames, the only affect here is for those after a firmware restart.

2021-08-26iwlwifi: mvm: Add support for hidden network scan on 6GHz bandIlan Peer2-15/+76
Add support for discovery of hidden networks on the 6GHz band, by including the scan request direct SSIDs in the FW scan request command: - In case a short SSID matches one of the direct SSIDs in the scan request command, add the matching SSID in the same offset in the 'direct_ssids' array. - Otherwise, add the SSID in one of the available slots. Additionally, as a preparation to handle hidden APs, refactor iwl_mvm_umac_scan_cfg_channels_v6_6g() the function.

2021-08-26iwlwifi: pcie: dump error on FW reset handshake failuresJohannes Berg3-6/+24
If the firmware crashes while we're waiting for the reset handshake then it cannot possibly make progress anymore, and we will just time out the wait. That's pointless, so just stop waiting at that point. Additionally, if it never acknowledges the reset handshake, something went wrong. Dump an error in both of these cases, but we need to do it synchronously here since the device will be turned off.

2021-08-26iwlwifi: pcie: free RBs during configureJohannes Berg2-1/+7
When switching op-modes, or more generally when reconfiguring, we might switch the RB size. In _iwl_pcie_rx_init() we have a comment saying we must free all RBs since we might switch the size, but this is actually too late: the switch has been done and we'll free the buffers with the wrong size. Fix this by always freeing the buffers, if any, at the start of configure, instead of only after the size may have changed.
