Pull networking fixes from Jakub Kicinski: "Including fixes from netfilter, wifi and ipsec. A little more changes than usual, but it's pretty normal for us that the rc3/rc4 PRs are oversized as people start testing in earnest. Possibly an extra boost from people deploying the 6.1 LTS but that's more of an unscientific hunch.

wifi: cfg80211: Partial revert "wifi: cfg80211: Fix use after free for wext"

2023-03-12T23:21:59Z

This reverts part of commit 015b8cc5e7c4 ("wifi: cfg80211: Fix use after free for wext") This commit broke WPA offload by unconditionally clearing the crypto modes for non-WEP connections. Drop that part of the patch.

wifi: cfg80211: fix MLO connection ownership

2023-03-10T10:47:25Z

When disconnecting from an MLO connection we need the AP MLD address, not an arbitrary BSSID. Fix the code to do that.

wifi: nl80211: fix puncturing bitmap policy

2023-03-10T10:46:45Z

This was meant to be a u32, and while applying the patch I tried to use policy validation for it. However, not only did I copy/paste it to u8 instead of u32, but also used the policy range erroneously. Fix both of these issues.

wifi: nl80211: fix NULL-ptr deref in offchan check

2023-03-10T10:46:22Z

If, e.g. in AP mode, the link was already created by userspace but not activated yet, it has a chandef but the chandef isn't valid and has no channel. Check for this and ignore this link.

wifi: wext: warn about usage only once

2023-02-26T17:53:35Z

Warn only once since the ratelimit parameters are still allowing too many messages to happen. This will no longer tell you all the different processes, but still gives a heads-up of sorts. Also modify the message to note that wext stops working for future Wi-Fi 7 hardware, this is already implemented in commit 4ca69027691a ("wifi: wireless: deny wireless extensions on MLO-capable devices") and is maybe of more relevance to users than the fact that we'd like to have wireless extensions deprecated. The issue with Wi-Fi 7 is that you can now have multiple connections to the same AP, so a whole bunch of things now become per link rather than per netdev, which can't really be handled in wireless extensions.

wifi: cfg80211: Set SSID if it is not already set

2023-02-15T17:26:58Z

When a connection was established without going through NL80211_CMD_CONNECT, the ssid was never set in the wireless_dev struct. Now we set it in __cfg80211_connect_result() when it is not already set. When using a userspace configuration that does not call cfg80211_connect() (can be checked with breakpoints in the kernel), this patch should allow `networkctl status device_name` to output the SSID instead of null.

wifi: cfg80211: call reg_notifier for self managed wiphy from driver hint

2023-02-14T11:37:39Z

Currently the regulatory driver does not call the regulatory callback reg_notifier for self managed wiphys. Sometimes driver needs cfg80211 to calculate the info of ieee80211_channel such as flags and power, and driver needs to get the info of ieee80211_channel after hint of driver, but driver does not know when calculation of the info of ieee80211_channel become finished, so add notify to driver in reg_process_self_managed_hint() from cfg80211 is a good way, then driver could get the correct info in callback of reg_notifier.

wifi: nl80211: Allow authentication frames and set keys on NAN interface

2023-02-14T11:35:02Z

Wi-Fi Aware R4 specification defines NAN Pairing which uses PASN handshake to authenticate the peer and generate keys. Hence allow to register and transmit the PASN authentication frames on NAN interface and set the keys to driver or underlying modules on NAN interface. The driver needs to configure the feature flag NL80211_EXT_FEATURE_SECURE_NAN, which also helps userspace modules to know if the driver supports secure NAN.
