2021-04-17rtlwifi: 8821ae: upgrade PHY and RF parametersPing-Ke Shih
The signal strength of 5G is quite low, so user can't connect to an AP far away. New parameters with new format and its parser are updated by the commit 84d26fda52e2 ("rtlwifi: Update 8821ae new phy parameters and its parser."), but some parameters are missing. Use this commit to update to the novel parameters that use new format.

2021-04-14iwlwifi: trans/pcie: defer transport initialisationJohannes Berg
In a few PCIe devices we may have to swap out the configuration after we allocate/initialise some parts of the device because we only know the correct one after reading some registers. This causes some things such as the byte-count table allocations to be incorrect, since the configuration is swapped for one with a bigger queue size. Fix this by initialising most of the transport much later, only after the configuration has finally been determined.

When we switch channel, we may miss a few beacons on the new channel. Don't disconnect if the time event for the switch ends before we hear the beacons. Note that this is relevant only for old devices that still use the TIME_EVENT firmware API for channel switch. The check that we hear a beacon before the time event ends was meant to be used for the association time event and not for the channel switch time event.

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: pcie: make cfg vs. trans_cfg more robustJohannes Berg
If we (for example) have a trans_cfg entry in the PCI IDs table, but then don't find a full cfg entry for it in the info table, we fall through to the code that treats the PCI ID table entry as a full cfg entry. This obviously causes crashes later, e.g. when trying to build the firmware name string. Avoid such crashes by using the low bit of the pointer as a tag for trans_cfg entries (automatically using a macro that checks the type when assigning) and then checking that before trying to use the data as a full entry - if it's just a partial entry at that point, fail. Since we're adding some macro magic, also check that the type is in fact either struct iwl_cfg_trans_params or struct iwl_cfg, failing compilation ("initializer element is not constant") if it isn't.

2021-04-14iwlwifi: pcie: clear only FH bits handle in the interruptMordechay Goodstein
For simplicity we assume that msix has 2 IRQ lines one used for rx data called msix_non_share, and another used for one bit flags messages (alive, hw error, sw error, rx data flag) called msix_share. Every time the FW has data to send it puts it on the RX queue and HW turns on the flags in msix_share (inta_fw) indicating about rx data, and HW sends an interrupt a bit later to the msix_non_share _unless_ the msix_shared RX data bit was cleared. Currently in the code every time we get an msix_shared we clear all bits including rx data queue bits. So we can have a race ---------------------------------------------------- DRIVER | HW | FW ---------------------------------------------------- - send host cmd to FW | | | | - handle message | | and put a response | | on the RX queue | - RX flag on | | | - send alive msix | - alive flag on | | - interrupt | | msix_share driver | - handle msix_shared | | and clear all flags | | bits | | | - don't send an | | interrupt on | | msix_non_shared | | (driver cleared) | - driver timeout on | | waiting for host cmd | | respond | | | | ---------------------------------------------------- The change is to clear only the msi_shared flags that are handled in the msix_shared flow, which will cause the hardware to send an interrupt on the msix_non_share line as well, when it has data.

2021-04-14iwlwifi: mvm: don't allow CSA if we haven't been fully associatedEmmanuel Grumbach
"Fully associated" means that we heard a beacon with the DTIM information and the firmware is configured to track the beacons. Since the firmware needs to track the beacons for the CSA, we can't configure the firmware for CSA before it knows when the beacons are expected otherwise we'd get ASSERT 301D. If we are required to start CSA before we told the firmware when the beacons are expected to arrive, just report a failure and let mac80211 disconnect.

2021-04-14iwlwifi: pcie: normally grab NIC access for inflight-hcmdJohannes Berg
We currently have a special, separate, code path to acquire NIC access for the in-flight host-command workaround on 7000 series hardware. However, the normal code path here has grown a number of additional workarounds/semantics over time, such as reprobing the device if things fail. Rather than try to replicate any of this logic, call the normal grab_nic_access logic for the workaround. This changes the spinlock to _bh, but that's OK since it's just redundant, we already have soft-IRQs disabled when we get here, and so didn't (have to) do it again. Since it's only for commands there's however no point in making the code more complex just to not use _bh here.

2021-04-14iwlwifi: mvm: enable TX on new CSA channel before disconnectingSara Sharon
When moving to the new channel, we block TX until we hear the first beacon. if it is not heard, we proceed to disconnect. Since TX is blocked (without mac80211 being aware of it) the frame is stuck, resulting with queue hang. Instead, reenable TX before reporting on the connection loss. As we are on the new channel, there is no problem with that, even if the original CSA had quiet mode.

2021-04-13of: net: pass the dst buffer to of_get_mac_address()Michael Walle
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.
