If the tables we get in the iwl_sar_set_profile() is smaller than the revision we support, we need to fill the values with 0. Make sure that's the case. Signed-off-by:

The tables we store are the larger of all the revisions, so we need to fill in the values that we don't get from ACPI when using older revisions. Signed-off-by:

Revisions 0 and 1 are identical, so we were already supporting that. But revision 2 has a different size, so we have to try to read them separately. Add support for this new revision. Signed-off-by:

We used to load the regdomain only in the load stage, this caused the 'iw phy phy0 reg get' command to fail if we booted a machine with wifi off. Therefor we should load it in INIT stage already. Signed-off-by:

We used to read the PPAG, WRDS, EWRD, WGDS tables from ACPI in the load stage only. This prevented vendor commands from being executed before bringing the interface up. Move reading those tables to INIT stage. Signed-off-by:

If the session protection ends but no beacon was heard, the driver triggers a disconnection. Trigger WRT in that case so it can be debugged. Signed-off-by:

In commit 79f033f6 ("iwlwifi: dbg: don't limit dump decisions to all or monitor") we changed the code to pass around a bitmap, but in the monitor_only case, one place accidentally used the bit number, not the bit mask, resulting in CSR and FW_INFO getting dumped instead of monitor data. Fix that. Signed-off-by:

By mistake we were considering the first element of the WTAS wifi package as part of the data we want to rid, but that element is the wifi package signature (always 0x07), so it should be skipped. Change the code to read the data starting from element 1 instead. Signed-off-by:

The new version of the command has same size and layout as version 10. It just sends corresponding station id in one of the reserved fields. It's not used in the driver, so just be ready to accept version 11. Signed-off-by:

The GEO profiles have been stored in single-dimension arrays and the access has been done via a single index. We will soon need to support different revisions of this table, which will make the flat array even harder to handle. To prepare for that, convert the single-dimension array to a struct with substructures. Signed-off-by:

When we started supporting the new FW API for the geo profiles, we stopped using this definition, but left it there. Remove it now. Signed-off-by:

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. Signed-off-by:

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.

The number of chains and sub-bands read from the ACPI tables varies depending on the revision. Pass these numbers to the iwl_sar_set_profile() function in order to make using different revisions easier. Signed-off-by:

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. Signed-off-by:

The "LIMITS" in the macro name don't have much meaning, so remove it to make the macro shorter and better reflect that this is the number of chains that we have limits for. Signed-off-by:

- Short SSIDs should always be added for direct SSIDs included in the scan request. However, this was not done in case that information for collocated APs was included. Fix this. - With the above fix, if the FW also supports discovery of hidden APs over the 6GHz band, also set the corresponding full SSID information. Signed-off-by:

When a station is removed, the driver-mac80211 station mapping is removed before the station is actually deleted from the FW. As a result, it is reasonable that the FW will continue to pass frames although the driver doesn't have a station for them anymore. Thus change the message severity level from ERR to DEBUG_DROP.

In later firmware we haven't needed the TSC anyway since we have it already (and firmware image doesn't change), but the new version adds the ability to send down replay counters for more than one GTK. Implement that. Signed-off-by:

If we're sending the KEK/KCK data we also need the GTK and IGTK type, add a separate key iteration for that so we can make the configure_key iteration optional later. Signed-off-by:

We do a key iteration to program the keys, and while at it we also collect the data necessary for TKIP. This code has all kinds of dependencies on the firmware API though, so take out the TKIP phase 1 key generation and do that in a separate key iteration only if necessary. Signed-off-by:

Both 'iwl_scan_probe_params_v3' and 'iwl_scan_probe_params_v4' wrongly addressed the 'bssid_array' field which should supposed to be any array of BSSIDs each of size ETH_ALEN and not the opposite. Fix it. Signed-off-by:

Since switching to mac80211 TXQs, we no longer need to advertise more hardware queues than ACs, since we don't even set QUEUE_CONTROL anyway, so the vif->hw_queue[] mapping array won't be used. All we need (at least for now) is for hw->queues to indicate that we have enough queues to handle QoS. Signed-off-by:
-
Johannes Berg authored
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.
