5c65ad6c0b PASN: Support PASN with FT key derivation
Add support for PASN authentication with FT key derivation:

- As IEEE P802.11az/D2.6 states that wrapped data is optional and
  is only needed for further validation of the FT security parameters,
  do not include them in the first PASN frame.

- PASN with FT key derivation requires knowledge of the PMK-R1 and
  PMK-R1-Name for the target AP. As the WPA state machine stores PMK-R1,
  etc. only for the currently associated AP, store the mapping of
  BSSID to R1KH-ID for each previous association, so the R1KH-ID
  could be used to derive PMK-R1 and PMK-R1-Name. Do so instead
  of storing the PMK-R1 to avoid maintaining keys that might not
  be used.

a4e3691616 WPA: Add PTKSA cache implementation
In order to be able to perform secure LTF measurements, both the
initiator and the responder need to first derive TK and KDK and store
them, so they would later be available for the secure LTF negotiation.

which can later be used for secure LTF negotiation, and add it to the

The operating class 129 includes channels with a maximum bandwidth of
160 MHz with center frequency index 50 and 114. The previous definition
of operating class 129 considered the center frequency index as actual

Fix the definition of operating class 129 to consider channels with the
center frequency index of 50 and 114.

Also update the comment that describes the channel selection for
operating 128, 129, and 130 which mentions wpas_p2p_allow_channel()
verifies the channels while wpas_p2p_verify_channel() takes care of it.

959af4f576 DPP: Abort authentication if no Auth Confirm is received within a second
After sending DPP Auth Response, the Responder might not receive the
Auth Confirm either due to the Initiator not sending it or the reception
of the frame failing for some reason (e.g., Responder having already
left the negotiation channel). If this happens, following initiation
attempts would fail since the consecutive Auth Request would get
discarded since the previous authentication is still in progress.

Terminate DPP authentication on Responder, if no Auth Confirm is
received within one second of successfully sending Auth Response. This
allows the Responder to accept start of a new exchange.

62657365f8 Add a configuration to disconnect on deinit if WoWLAN is enabled
Commit 02c21c02d0 ("wpa_supplicant: Do not disconnect on deinit if
WoWLAN is enabled") prevents the disconnection on deinit if the driver
indicates that WoWLAN is enabled. This is not the expected behavior in
some earlier use cases where the wpa_supplicant process is left running
when going to sleep and killing of the wpa_supplicant process is used
only when there is an expectation of Wi-Fi connection being disabled.

To support the use cases which require the WLAN to disconnect on deinit
even if WoWLAN is enabled, introduce a configuration parameter
wowlan_disconnect_on_deinit. This is set to 0 by default thereby not
impacting the functionality in the above mentioned commit. Setting it to
1 restores the old behavior before the commit identified above.

41fae6e0bb nl80211: Add missing WPA3-SAE auth_data in auth retry case
When wpa_supplicant sends NL80211_CMD_AUTHENTICATE to kernel, it is
possible that the cfg80211 in kernel has expired the BSS entry that
we are trying to auth with. Then cfg80211 will reject the auth cmd.
In this case, wpa_supplicant will trigger a single channel scan to
refresh cfg80211 BSS entry, and retry the auth when scan is finished.

When this case happens, wpa_supplicant makes a copy of auth params,
such as frequency, bssid, ssid, ie and so on. So when we retry auth,
the copy of these params will be used. The problem is, a param named
auth_data is missed when making the copy. The auth_data is used by
NL80211_ATTR_SAE_DATA which is a mandatory field for WPA3-SAE auth.
In WPA3-SAE case the auth retry will always fail because auth_data is
missing. This patch fixes the issue.

71718b628b FT: Update key mgmt properly in RSNE during roaming
When STA is performing roam from WPA3 AP to WPA2 AP, the STA was
including key mgmt FT-SAE instead of FT-PSK in FT Authentication request
RSNE when using driver-based SME. This is because the RSNE/MDE/FTE were
updated and forwarded to the driver using the NL80211_CMD_UPDATE_FT_IES
command before updating key mgmt properly. Because of this, the AP is
rejecting FT Authentication request with WLAN_REASON_UNSPECIFIED reason
code which is due to the invalid keymgmt in RSNE.

Fix this by reordering IE population to happen earlier in the sequence
so that the updated key mgmt information can be provided when using
NL80211_CMD_UPDATE_FT_IES.
