Code Issues Releases Wiki Activity

Quite a few changes: 

* the applicable eth_hw_addr_set() and const hw_addr changes
  * various code cleanups/refactorings
  * stack usage reductions across the wireless stack
  * some unstructured find_ie() -> structured find_element()
    changes
  * a few more pieces of multi-BSSID support
  * some 6 GHz regulatory support
  * 6 GHz support in hwsim, for testing userspace code
  * Light Communications (LC, 802.11bb) early band definitions
    to be able to add a first driver soon

* the user space can run the following flow to be able to get connected
* to the very same AP the CSME firmware is currently connected to:
*
* 1) The user space (NetworkManager) boots and sees that the device is
* in RFKILL because the host doesn't own the device
* 2) The user space asks the kernel what AP the CSME firmware is
* connected to (with %IWL_MVM_VENDOR_CMD_GET_CSME_CONN_INFO)
* 3) The user space checks if it has a profile that matches the reply
* from the CSME firmware
* 4) The user space installs a network to the wpa_supplicant with a
* specific BSSID and a specific frequency
* 5) The user space prevents any type of full scan
* 6) The user space asks iwlmei to request ownership on the device (with
* this command)
* 7) iwlmei requests ownership from the CSME firmware
* 8) The CSME firmware grants ownership
* 9) iwlmei tells iwlwifi to lift the RFKILL
* 10) RFKILL OFF is reported to user space
* 11) The host boots the device, loads the firwmare, and connects to a
* specific BSSID without scanning including IP as fast as it can
* 12) The host reports to the CSME firmware that there is a connection

* DOC: FILS shared key crypto offload
*
* This feature is applicable to drivers running in AP mode.
*
* FILS shared key crypto offload can be advertised by drivers by setting
* @NL80211_EXT_FEATURE_FILS_CRYPTO_OFFLOAD flag. The drivers that support
* FILS shared key crypto offload should be able to encrypt and decrypt
* association frames for FILS shared key authentication as per IEEE 802.11ai.
* With this capability, for FILS key derivation, drivers depend on userspace.
*
* After FILS key derivation, userspace shares the FILS AAD details with the
* driver and the driver stores the same to use in decryption of association
* request and in encryption of association response. The below parameters
* should be given to the driver in %NL80211_CMD_SET_FILS_AAD.
* %NL80211_ATTR_MAC - STA MAC address, used for storing FILS AAD per STA
* %NL80211_ATTR_FILS_KEK - Used for encryption or decryption
* %NL80211_ATTR_FILS_NONCES - Used for encryption or decryption
* (STA Nonce 16 bytes followed by AP Nonce 16 bytes)
