Apparently the hex passphrase mechanism does not work on newer chips/firmware (e.g. BCM4387). It seems there was a simple way of passing it in binary all along, so use that and avoid the hexification. OpenBSD has been doing it like this from the beginning, so this should work on all chips. Also clear the structure before setting the PMK. This was leaking uninitialized stack contents to the device. Reviewed-by:

Add support for the new PMKID_V3 API, which allows performing PMKID mutations individually, instead of requiring the driver to keep track of the full list. This new API is required by at least BCM4387. Note that PMKID_V2 is not implemented yet. Reviewed-by:

At least on BCM4387, the D11 cores are held in reset on cold startup and firmware expects to release reset itself. Just assert reset here and let firmware deassert it. Premature deassertion results in the firmware failing to initialize properly some of the time, with strange AXI bus errors. Also, BCM4387 has 3 cores, up from 2. The logic for handling that is in brcmf_chip_ai_resetcore(), but since we aren't using that any more, just handle it here. Reviewed-by:

Using the BCM4339 firmware from linux-firmware (version "BCM4339/2 wl0: Sep 5 2019 11:05:52 version 6.37.39.113 (r722271 CY)" from cypress/cyfmac4339-sdio.bin) the RSSI respose is only 4 bytes, which results in an error being logged. It seems that older devices send only the RSSI field and neither SNR nor noise is included. Handle this by accepting a 4 byte message and reading only the RSSI from it.

Newer Apple firmwares on chipsets without a hardware RNG require the host to provide a buffer of 256 random bytes to the device on initialization. This buffer is present immediately before NVRAM, suffixed by a footer containing a magic number and the buffer length. This won't affect chips/firmwares that do not use this feature, so do it unconditionally for all Apple platforms (those with an Apple OTP). Reviewed-by:

On DT platforms, the module-instance and antenna-sku-info properties are passed in the DT. On ACPI platforms, module-instance is passed via the analogous Apple device property mechanism, while the antenna SKU info is instead obtained via an ACPI method that grabs it from non-volatile storage. Add support for this, to allow proper firmware selection on Apple platforms. Signed-off-by:

The newer chips use the newer firmware branches, e.g. v027, v029. And, those firmware branches are supposed to support packet drop when they are just branched out. The initial firmware branch used by each chip is as below. * 8852A: v009 * 8852C: v027 * 8852B: v027 So, only 8852A may use firmware which doesn't support packet drop at runtime. To save trivial positive listing in firmware feature table, we change to reverse judgment. Besides, rtw89_mac_ptk_drop_by_band_and_wait() missed to check firmware feature before calling rtw89_fw_h2c_pkt_drop(). We also fix it. Signed-off-by:

Since 6 GHz band has around 60 channels and more strict rules for active probing. Reduced neighbor report can be used to reduce the channels we scan and get specific target BSS info to probe for. Declare flag WIPHY_FLAG_SPLIT_SCAN_6GHZ so the scan request could be divided into two portions: legacy bands and 6 GHz bands. So RNR information from legacy bands could later be used when 6 GHz scan. When the scan flag NL80211_SCAN_FLAG_COLOCATED_6GHZ is set, cfg80211 will pass down a reduced channel set which contains PSCs and non-PSC with RNR info received in the 2 GHz/5 GHz band. This reduces the scan duration by allowing us to only scan for channels in which APs are currently operating. Signed-off-by:

Paul Blakey says: ==================== net/sched: cls_api: Support hardware miss to tc action This series adds support for hardware miss to instruct tc to continue execution in a specific tc action instance on a filter's action list. The mlx5 driver patch (besides the refactors) shows its usage instead of using just chain restore. Currently a filter's action list must be executed all together or not at all as driver are only able to tell tc to continue executing from a specific tc chain, and not a specific filter/action. This is troublesome with regards to action CT, where new connections should be sent to software (via tc chain restore), and established connections can be handled in hardware. Checking for new connections is done when executing the ct action in hardware (by checking the packet's tuple against known established tuples). But if there is a packet modification (pedit) action before action CT and the checked tuple is a new connection, hardware will need to revert the previous packet modifications before sending it back to software so it can re-match the same tc filter in software and re-execute its CT action. The following is an example configuration of stateless nat on mlx5 driver that isn't supported before this patchet: #Setup corrosponding mlx5 VFs in namespaces $ ip netns add ns0 $ ip netns add ns1 $ ip link set dev enp8s0f0v0 netns ns0 $ ip netns exec ns0 ifconfig enp8s0f0v0 1.1.1.1/24 up $ ip link set dev enp8s0f0v1 netns ns1 $ ip netns exec ns1 ifconfig enp8s0f0v1 1.1.1.2/24 up #Setup tc arp and ct rules on mxl5 VF representors $ tc qdisc add dev enp8s0f0_0 ingress $ tc qdisc add dev enp8s0f0_1 ingress $ ifconfig enp8s0f0_0 up $ ifconfig enp8s0f0_1 up #Original side $ tc filter add dev enp8s0f0_0 ingress chain 0 proto ip flower \ ct_state -trk ip_proto tcp dst_port 8888 \ action pedit ex munge tcp dport set 5001 pipe \ action csum ip tcp pipe \ action ct pipe \ action goto chain 1 $ tc filter add dev enp8s0f0_0 ingress chain 1 proto ip flower \ ct_state +trk+est \ action mirred egress redirect dev enp8s0f0_1 $ tc filter add dev enp8s0f0_0 ingress chain 1 proto ip flower \ ct_state +trk+new \ action ct commit pipe \ action mirred egress redirect dev enp8s0f0_1 $ tc filter add dev enp8s0f0_0 ingress chain 0 proto arp flower \ action mirred egress redirect dev enp8s0f0_1 #Reply side $ tc filter add dev enp8s0f0_1 ingress chain 0 proto arp flower \ action mirred egress redirect dev enp8s0f0_0 $ tc filter add dev enp8s0f0_1 ingress chain 0 proto ip flower \ ct_state -trk ip_proto tcp \ action ct pipe \ action pedit ex munge tcp sport set 8888 pipe \ action csum ip tcp pipe \ action mirred egress redirect dev enp8s0f0_0 #Run traffic $ ip netns exec ns1 iperf -s -p 5001& $ sleep 2 #wait for iperf to fully open $ ip netns exec ns0 iperf -c 1.1.1.2 -p 8888 #dump tc filter stats on enp8s0f0_0 chain 0 rule and see hardware packets: $ tc -s filter show dev enp8s0f0_0 ingress chain 0 proto ip | grep "hardware.*pkt" Sent hardware 9310116832 bytes 6149672 pkt Sent hardware 9310116832 bytes 6149672 pkt Sent hardware 9310116832 bytes 6149672 pkt A new connection executing the first filter in hardware will first rewrite the dst port to the new port, and then the ct action is executed, because this is a new connection, hardware will need to be send this back to software, on chain 0, to execute the first filter again in software. The dst port needs to be reverted otherwise it won't re-match the old dst port in the first filter. Because of that, currently mlx5 driver will reject offloading the above action ct rule. This series adds support for hardware partially executing a filter's action list, and letting tc software continue processing in the specific action instance where hardware left off (in the above case after the "action pedit ex munge tcp dport... of the first rule") allowing support for scenarios such as the above. ==================== Link: https://lore.kernel.org/r/20230217223620.28508-1-paulb@nvidia.comSigned-off-by: -

Currently, CT misses restore the missed chain on the tc skb extension so tc will continue from the relevant chain. Instead, restore the CT action's miss cookie on the extension, which will instruct tc to continue from the this specific CT action instance on the relevant filter's action list. Map the CT action's miss_cookie to a new miss object (ACT_MISS), and use this miss mapping instead of the current chain miss object (CHAIN_MISS) for CT action misses. To restore this new miss mapping value, add a RX restore rule for each such mapping value. Signed-off-by:

For drivers to support partial offload of a filter's action list, add support for action miss to specify an action instance to continue from in sw. CT action in particular can't be fully offloaded, as new connections need to be handled in software. This imposes other limitations on the actions that can be offloaded together with the CT action, such as packet modifications. Assign each action on a filter's action list a unique miss_cookie which drivers can then use to fill action_miss part of the tc skb extension. On getting back this miss_cookie, find the action instance with relevant cookie and continue classifying from there. Signed-off-by:
