2024-07-09wifi: cfg80211: add support for advertising multiple radios belonging to a wiphyFelix Fietkau
The prerequisite for MLO support in cfg80211/mac80211 is that all the links participating in MLO must be from the same wiphy/ieee80211_hw. To meet this expectation, some drivers may need to group multiple discrete hardware each acting as a link in MLO under single wiphy. With this change, supported frequencies and interface combinations of each individual radio are reported to user space. This allows user space to figure out the limitations of what combination of channels can be used concurrently. Even for non-MLO devices, this improves support for devices capable of running on multiple channels at the same time.

Add a regulatory flag to allow VLP AP operation even on channels otherwise marked NO_IR, which may be possible in some regulatory domains/countries. Note that this requires checking also when the beacon is changed, since that may change the regulatory power type.

kernel-doc flagged the following issue: include/uapi/linux/nl80211.h:6081: warning: expecting prototype for enum nl80211_plink_action. Prototype was for enum plink_actions instead This is because the documentation doesn't match the code. Normally the correct fix for such an issue is to modify the documentation to match the code.

2024-02-12wifi: cfg80211: optionally support monitor on disabled channelsJohannes Berg
If the hardware supports a disabled channel, it may in some cases be possible to use monitor mode (without any transmit) on it when it's otherwise disabled. Add a new channel flag IEEE80211_CHAN_CAN_MONITOR that makes it possible for a driver to indicate such a thing. Make it per channel so drivers could have a choice with it, perhaps it's only possible on some channels, perhaps some channels are not supported at all, but still there and marked disabled. In _nl80211_parse_chandef() simplify the code and check only for an unknown channel, _cfg80211_chandef_usable() will later check for IEEE80211_CHAN_DISABLED anyway.

2024-02-12wifi: cfg80211: add support for link id attribute in NL80211_CMD_DEL_STATIONAditya Kumar Singh
Currently whenever NL80211_CMD_DEL_STATION command is called without any MAC address, all stations present on that interface are flushed. However with MLO there is a need to flush such stations only which are using at least a particular link from the AP MLD interface. For example - 2 GHz and 5 GHz are part of an AP MLD. To this interface, following stations are connected - 1. One non-EHT STA on 2 GHz link. 2. One non-EHT STA on 5 GHz link. 3. One Multi-Link STA having 2 GHz and 5 GHz as active links. Now if currently, NL80211_CMD_DEL_STATION is issued by the 2 GHz link without any MAC address, it would flush all station entries. However, flushing of station entry #2 at least is not desireable since it is connected to 5 GHz link alone. Hence, add an option to pass link ID as well in the command so that if link ID is passed, stations using that passed link ID alone would be flushed and others will not. So after this, station entries #1 and #3 alone would be flushed and #2 will remain as it is.

2024-01-26Revert "nl80211/cfg80211: Specify band specific min RSSI thresholds with ↵Jeff Johnson
sched scan" This *mostly* reverts commit 1e1b11b6a111 ("nl80211/cfg80211: Specify band specific min RSSI thresholds with sched scan"). During the review of a new patch [1] it was observed that the functionality being modified was not actually being used by any in-tree driver. Further research determined that the functionality was originally introduced to support a new Android interface, but that interface was subsequently abandoned. Since the functionality has apparently never been used, remove it. However, to mantain the sanctity of the UABI, keep the nl80211.h assignments, but clearly mark them as obsolete.

2024-01-26wifi: cfg80211: add support for SPP A-MSDUsJohannes Berg
Add SPP (signaling and payload protected) AMSDU support. Since userspace has to build the RSNX element, add an extended feature flag to indicate that this is supported. In order to avoid downgrade/mismatch attacks, add a flag to the assoc command on the station side, so that we can be sure that the value of the flag comes from the same RSNX element that will be validated by the supplicant against the 4-way-handshake. If we just pulled the data out of a beacon/probe response, we could theoretically look an RSNX element from a different frame, with a different value for this flag, than the supplicant is using to validate in the 4-way-handshake. Note that this patch is only geared towards software crypto implementations or hardware ones that can perfectly implement SPP A-MSDUs, i.e. are able to switch the AAD construction on the fly for each TX/RX frame. For more limited hardware implementations, more capability advertisement would be required, e.g. if the hardware has no way to switch this on the fly but has only a global configuration that must apply to all stations. The driver could of course *reject* mismatches, but the supplicant must know so it can do things like not negotiating SPP A-MSDUs on a T-DLS link when connected to an AP that doesn't support it, or similar.

2023-12-12wifi: cfg80211: add BSS usage reportingJohannes Berg
Sometimes there may be reasons for which a BSS that's actually found in scan cannot be used to connect to, for example a nonprimary link of an NSTR mobile AP MLD cannot be used for normal direct connections to it. Not indicating these to userspace as we do now of course avoids being able to connect to them, but it's better if they're shown to userspace and it can make an appropriate decision, without e.g. doing an additional ML probe. Thus add an indication of what a BSS can be used for, currently "normal" and "MLD link", including a reason bitmap for it being not usable. The latter can be extended later for certain BSSes if there are other reasons they cannot be used.

Add new nested attribute NL80211_ATTR_EMA_RNR_ELEMS to support the above. Number of RNR elements must be more than or equal to the number of MBSSID elements. This attribute can be used only when EMA is enabled. Userspace is responsible for splitting the RNR into multiple elements such that each element excludes the non-transmitting profiles already included in the MBSSID element (%NL80211_ATTR_MBSSID_ELEMS) at the same index. Each EMA beacon will be generated by adding MBSSID and RNR elements at the same index. If the userspace provides more RNR elements than the number of MBSSID elements then these will be added in every EMA beacon.

Add support to use a random local address in authentication and deauthentication frames sent to unassociated peer when the driver supports. The driver needs to configure receive behavior to accept frames with random transmit address specified in TX path authentication frames during the time of the frame exchange is pending and such frames need to be acknowledged similarly to frames sent to the local permanent address when this random address functionality is used. This capability allows use of randomized transmit address for PASN authentication frames to improve privacy of WLAN clients.

2023-02-14wifi: cfg80211: Authentication offload to user space for MLO connection in ↵Veerendranath Jakkam
STA mode Currently authentication request event interface doesn't have support to indicate the user space whether it should enable MLO or not during the authentication with the specified AP. But driver needs such capability since the connection is MLO or not decided by the driver in case of SME offload to the driver. Add support for driver to indicate MLD address of the AP in authentication offload request to inform user space to enable MLO during authentication process. Driver shall look at NL80211_ATTR_MLO_SUPPORT flag capability in NL80211_CMD_CONNECT to know whether the user space supports enabling MLO during the authentication offload. User space should enable MLO during the authentication only when it receives the AP MLD address in authentication offload request. User space shouldn't enable MLO if the authentication offload request doesn't indicate the AP MLD address even if the AP is MLO capable. When MLO is enabled, user space should use the MAC address of the interface (on which driver sent request) as self MLD address. User space and driver to use MLD addresses in RA, TA and BSSID fields of the frames between them, and driver translates the MLD addresses to/from link addresses based on the link chosen for the authentication.

Increase akm_suites array size in struct cfg80211_crypto_settings to 10 and advertise the capability to userspace. This allows userspace to send more than two AKMs to driver in netlink commands such as NL80211_CMD_CONNECT. This capability is needed for implementing WPA3-Personal transition mode correctly with any driver that handles roaming internally. Currently, the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256, SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing the akm_suites array size to 10 should be reasonable for future usecases.
