Add a location for storing expiration time for DevIK. For now, this is

Commit 891bb1305bbd ("P2P: Enforce SAE-H2E for P2P GO in 6 GHz")
introduced a network profile specific sae_pwe to avoid having to change
the global sae_pwe parameter. However, this was enabled only for AP/P2P
GO mode. Extend that to cover STA mode as well.
Extend EAPOL frames processing workaround for reassociation to same AP
With commit 3ab35a660364 ("Extend EAPOL frames processing workaround for
roaming cases") wpa_supplicant postpones EAPOL frame processing till
roam indication from the driver when the source address of EAPOL frame
does not match the current BSSID/AP MLD MAC address.
However, this does not handle the cases in which STA tries to
reassociate with the current AP. When STA tries to reassociate with the
current AP, the source address of the EAPOL frame will be same as the
current BSSID. So, wpa_supplicant does not postpone the EAPOL frame from
the current connected AP since AP might have sent the EAPOL frame for
PTK rekey.
To address this issue, add additional support for reassociating to the
same AP case. Check if replay counter value of the new EAPOL frame is
greater than the reply counter of the last EAPOL frame, and if the new
EAPOL frame replay counter is less, postpone the new EAPOL frame
processing until roam indication from the driver.
STA: Update driver roaming policy on connection completion
When the network profile is configured with BSSID before connection,
roaming policy in the driver (for driver-based BSS selection) doesn't
get updated if the same BSSID is configured after connection. Update
roaming policy to the driver on connection completion to cover this
case.
Add TEST_RSNXE_DATA for RSNXE testing of AP functionality
Add support to set test data in the default RSNXE with wpa_supplicant
control interface command "TEST_RSNXE_DATA <data hexdump> <mask
hexdump>". This can be used to do protocol testing of AP side processing
of RSNXE.
Add QCA vendor status for TWT termination due to multiple MLO links activated
Add a new status value
QCA_WLAN_VENDOR_TWT_STATUS_MULTIPLE_LINKS_ACTIVE_TERMINATE to indicate

NAN: Handle A3 copying internally to simplify control interface
There is no need to copy the A3 value for follow-up frames through the
control interface events and commands since it can be handled internally
in the service with sufficient accuracy. More parallel operations with
multiple peers might need per-peer information, but that can be extended
in the future, if that level of complexity is really needed in practice.
This reverts commit 81322fa43d1d ("tests: Copy A3 into NAN SDF
Follow-up") to allow simplification of the control interface by removing
the external A3 copying.
NAN: Update A3 for USD to use NAN Network ID or NAN Cluster ID in A3
Wi-Fi Aware spec v4.0 was not clear on all cases and used a bit unclear
definition of A3 use in Table 5 (Address field definiton for NAN SDF
frames in USD). That resulted in the initial implementation using
Wildcard BSSID to comply with the IEEE 802.11 rules on Public Action
frame addressing.
For USD to have chances of working with synchronized NNA devices, A3
needs to be set to the NAN Cluster ID when replying to a frame received
from a synchronized NAN device. While there is no cluster ID for USD,
this can be done by copying the A3 from the received frame. For the
cases where sending out an unsolicited multicast frame, the NAN Network
ID should be used instead of the Wildcard BSSID.
While this behavior is not strictly speaking compliant with the IEEE
802.11 standard, this is the expected behavior for NAN devices, so
update the USD implementation to match.
hostapd: Add drv_send_action variant for forcing A3
This is needed for cases that are not compliant with the IEEE 802.11
standard rules for Public Action frame addressing. For example, NAN USD
needs this.
NAN: Process received NAN SDFs with NAN Network ID in A3 on AP
hostapd did not accept NAN SDFs that used NAN Network ID instead of
Wildcard BSSID in A3. Extend this to process NAN Network ID just like
Wildcard BSSID for these frames to allow the specific group address to
be used.
SAE: Recognize Basic MLE in Authentication frames even without H2E
IEEE P802.11be requires H2E to be used whenever SAE is used for ML
association. However, some early Wi-Fi 7 APs enable MLO without H2E.
Recognize this special case based on the fixed length Basic Multi-Link
element being at the end of the data that would contain the unknown
variable length Anti-Clogging Token field. The Basic Multi-Link element
in Authentication frames include the MLD MAC addreess in the Common Info
field and all subfields of the Presence Bitmap subfield of the
Multi-Link Control field of the element zero and consequently, has a
fixed length of 12 octets.
FT: Discard EAPOL-Start frames when FT was used for association
When FT is used, reauthentication to generate a new PMK-R0 would be
complicated since the current AP might not be the one with which the
currently used PMK-R0 was generated. IEEE Std 802.11-2020, 13.4.2 (FT
initial mobility domain association in an RSN) mandates STA to perform a
new FT initial mobility domain association whenever its Supplicant would
trigger sending of an EAPOL-Start frame.
Discard received EAPOL-Start frames from STAs that use FT to avoid
unexpected behavior. This is important in particular if a driver were to
allow unprotected EAPOL-Start frames to be processed when TK has been
configured.

nl80211: Pass "global" events to all interfaces
We got connection failures because of outdated channel information.
That's because the NL80211_CMD_REG_CHANGE event is important for all
interfaces.
Commit f13683720239 ("nl80211: Pass wiphy events to all affected

but that doesn't cover the regulatory change event because it doesn't

and from three interfaces, only one got the updated channel list.
Fix this by changing the early termination logic to only apply to events
directed either to a specific interface index for wdev.
AP MLD: Check SAE message length without depending on pointer arithemetic

AP MLD: Work around delayed STA entry addition for SAE confirm
The driver is expected to have an STA entry for a non-AP MLD ready to
translate the address fields for SAE confirm messages. However, there is
at least a theoretical race condition in a case where the peer sends the
SAE confirm message quickly enough for the driver translation mechanism
to not be available to update the SAE confirm message addresses. Work
around that by searching for the STA entry using the link address of the
non-AP MLD if no match is found based on the MLD MAC address.
AP MLD: Introduce MLD level control interface socket
With MLO, each link have socket created with "<ifname>_link<link id>"
under the control interface directory.
Introduce a MLD level socket "<ifname>" as well under the same control
interface directory. This socket can be used to pass the command to its
partner links directly instead of using the link level socket. Link ID
needs to be passed with the command in a prefix way. If no Link ID is
provided the first link ID is selected.
The structure of the command is -
"LINKID <link id> <COMMAND APPLICABALE FOR THE LINK>"
Directory looks something like this -
$ ls /var/run/hostapd/
wlan0
wlan0_link0
wlan0_link1
wlan0 here is the MLD level socket. Rest are each link level sockets.
This also helps to maintain backwards compatibility with applications
which looks for <ifname> under the control interface directory.
Create link based control sockets to access the link based commands
through hostapd_cli. This will create the link interfaces in the name of
<ifname>_link<X>
Example:
To fetch link 0 status from wlan0, below command can be used -
$ hostapd_cli -i wlan0 -l 0 status
On failure of link/interface selection, below error will be observed
$ hostapd_cli -i wlan0 -l 2 status
