wifi: cfg80211: add start/stop proximity detection commands

2026-05-05T11:36:30+00:00

Currently, the proximity detection (PD) interface type has no start/stop commands defined, preventing user space from controlling PD operations through the nl80211 interface. Add NL80211_CMD_START_PD and NL80211_CMD_STOP_PD commands to allow user space to start and stop a PD interface. Add the corresponding start_pd and stop_pd operations to cfg80211_ops and ieee80211_ops, along with nl80211 command handlers, rdev wrappers, and tracing support. Validate that drivers advertising PD interface support implement the required operations. Handle PD interface teardown during device unregistration and when the interface leaves the network.

wifi: cfg80211: Add MAC address filter to remain_on_channel

2026-05-05T11:25:27+00:00

Currently the remain_on_channel operation does not support filtering incoming frames by destination MAC address. This prevents use cases such as PASN authentication in the responder side that need to receive frames addressed to a specific MAC during the off-channel period. Add an rx_addr parameter to the remain_on_channel operation callback and propagate it through the call chain from nl80211 to driver implementations. Introduce the extended feature NL80211_EXT_FEATURE_ROC_ADDR_FILTER as a capability gate so that cfg80211 rejects the request if the driver does not advertise support for address filtering. Extract the address from the NL80211_ATTR_MAC attribute when provided in the netlink message and update the tracing infrastructure to include the address in remain_on_channel trace events. The rx_addr parameter is optional and can be NULL, maintaining backward compatibility with existing drivers.

wifi: nl80211: define an API for configuring the NAN peer's schedule

2026-03-25T19:56:55+00:00

Add an NL80211 command to configure the NAN schedule of a NAN peer. Such a schedule contains a list of NAN channels, and a mapping from each time slots to the corresponding channel (or unscheduled). Also contains more information about the schedule, such as sequence ID and map ID. Not all of the restrictions are validated in this patch. In particular, comparison of two maps of the same peer requires storing/retrieving each map of each peer, only for validation. Therefore, it is the responsibilty of the driver to check that.

wifi: cfg80211: Add an API to configure local NAN schedule

2026-03-25T19:56:05+00:00

Add an nl80211 API to allow user space to configure the local NAN schedule. The local schedule consists of a list of channel definitions and a schedule map, in which each element covers a time slot and indicates on what channel the device should be in that time slot. Channels can be added to schedule even without being scheduled, for reservation purposes. A schedule can be configured either immedietally or be deferred, in case there are already connected peers. When the deferred flag is set, the command is a request from the device to perform an announced schedule update: send the updated NAN Availability - as set in this command - to the peers, and do the actual switch to the new schedule on the right time (i.e. at the end of the slot after the slot in which the update was sent to the peers). In addition, a notification will be sent to indicate a deferred update completion.

wifi: cfg80211: support key installation on non-netdev wdevs

2026-03-02T10:28:33+00:00

Currently key installation is only supported for netdev. For NAN, support most key operations (except setting default data key) on wdevs instead of netdevs, and adjust all the APIs and tracing to match. Since nothing currently sets NL80211_EXT_FEATURE_SECURE_NAN, this doesn't change anything (P2P Device already isn't allowed.)

wifi: nl80211/cfg80211: support stations of non-netdev interfaces

2026-03-02T08:23:03+00:00

Currently, a station can only be added to a netdev interface, mainly because there was no need for a station of a non-netdev interface. But for NAN, we will have stations that belong to the NL80211_IFTYPE_NAN interface. Prepare for adding/changing/deleting a station that belongs to a non-netdev interface. This doesn't actually allow such stations - this will be done in a different patch.

wifi: cfg80211/mac80211: Add support to get radio index

2025-06-24T13:19:27+00:00

Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.
