2021-04-14iwlwifi: mvm: Add support for 6GHz passive scanIlan Peer
When doing scan while 6GHz channels are not enabled, the 6GHz band is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands (that will allow discovery of geographic location etc. that would allow enabling the 6GHz channels) but there are non collocated APs on 6GHz PSC channels these would never be discovered. To overcome this, FW added support for performing passive UHB scan in case no APs were discovered during scan on the 2GHz and 5GHz channels. Add support for enabling such scan when the following conditions are met: - 6GHz channels are supported but not enabled by regulatory. - Station interface is not associated or less than a defined time interval passed from the last resume or HW reset flows. - At least 4 channels are included in the scan request - The scan request includes the widlcard SSID. - At least 50 minutes passed from the last 6GHz passive scan.

2021-04-14iwlwifi: mvm: clean up queue sync implementationJohannes Berg
When we do queue sync, it's confusing that we have the structures declared in the FW API header files that aren't really firmware, and the union is also confusing - especially now in the code that checks the size on the return. So rework this: change the type of sync and whether to do it in a synchronous fashion to arguments, and build the data structure in the function, so we don't need the union.

2021-02-12iwlwifi: remove incorrect comment in pnvmLuca Coelho
We use this driver as a backport that also runs on older kernels (as part of the backports project). So we use some checks to backport or prevent code from compiling in incompatible kernel version. When I took one of the PNVM patches from the backport, I accidentally left the comment that a certain part of the code doesn't work in older kernels. This obviously should never be valid for the mainline. Remove this comment.

2021-02-10iwlwifi: acpi: fix PPAG table sizesLuca Coelho
We were erroneously adding 3 extra values to the table size calculation, when we should actually add only a 2 (one for the domain type and one for the enabled/disabled flag). Fix this for both revisions we support.

2021-02-05iwlwifi: fw api: make hdr a zero-size array againJohannes Berg
In struct iwl_tx_cmd, there's no risk (as Arnd implied) that we might access this as an array, as it's really not an array and cannot be - there's only a single 802.11 header per frame. The only reason for this member is for being able to access it a bit more nicely. On the other hand, this structure is used as a sub-struct in a few places, and then some compilers (e.g. clang with certain options) complain as you shouldn't have structs with variable- length fields embedded in other structs.

2021-02-05iwlwifi: mvm: advertise BIGTK client support if availableJohannes Berg
If the firmware has support, then advertise it to the stack and send the key down. Since we re-check the protection in the host anyway, we don't really need to do anything on RX except that we should drop frames that the firmware _knows_ are replay errors, since beacon filtering might otherwise result in replays being possible.

In the new api all the flush in the FW is done before we get the response and in the response we only get the updated read pointer and all queued packets don't get anymore rx_tx per packet to free the queued packet, so driver needs to free all queued packets on flushed queue at once after flush response.

2021-02-05iwlwifi: mvm: handle CCA-EXT delay firmware notificationJohannes Berg
If there are frequent CCA delays due to the extension channel as detected by the firmware, and we're on 2.4 GHz, then handle this by disconnecting (with a reconnect hint). When we disconnect, we'll also update our capabilities to use only 20 MHz on the next connection (if it's on 2.4 GHz) as to avoid the use of the extension channel that has too much noise.

2021-02-05iwlwifi: mvm: add notification size checksJohannes Berg
We shouldn't trust the firmware with the sizes (or contents) of notifications, accessing too much data could cause page faults if the data doesn't fit into the allocated space. This applies more on older NICs where multiple notifications can be in a single RX buffer. Add a general framework for checking a minimum size of any notification in the RX handlers and use it for most. Some RX handlers were already checking and I've moved the checks, some more complex checks I left and made them _NO_SIZE for the RX handlers.
