This adds experimental support for wpa_supplicant to assign random local
MAC addresses for both pre-association cases (scan, GAS/ANQP) and for
connections. MAC address policy for each part can be controlled
separately and the connection part can be set per network block.
This requires support from the driver to allow local MAC address to be
changed if random address policy is enabled. It should also be noted
that number of drivers would not support concurrent operations (e.g.,
P2P and station association) with random addresses in use for one or
both.
This functionality can be controlled with the global configuration
parameters mac_addr and preassoc_mac_addr which set the default MAC
address policies for connections and pre-association operations (scan
and GAS/ANQP while not connected). The global rand_addr_lifetime
parameter can be used to set the lifetime of a random MAC address in
seconds (default: 60 seconds). This is used to avoid unnecessarily
frequent MAC address changes since those are likely to result in driver
clearing most of its state. It should be noted that the random MAC
address does not expire during an ESS connection, i.e., this lifetime is
only for the case where the device is disconnected.
The mac_addr parameter can also be set in the network blocks to define
different behavior per network. For example, the global mac_addr=1 and
preassoc_mac_addr=1 settings and mac_addr=0 in a home network profile
would result in behavior where all scanning is performed using a random
MAC address while connections to new networks (e.g.,
Interworking/Hotspot 2.0) would use random address and connections to
the home network would use the permanent MAC address.

Some deployed APs send two credentials when in mixed-WPA/WPA2
configuration; one for the WPA-Personal/TKIP and the other for
WPA2-Personal/CCMP. Previously, this would result in two network blocks
getting added for the single AP. This can be somewhat confusing and
unnecessary, so merge such credentials into a single one that allows
both WPA and WPA2 to be used.

The new "scan_id=<comma separated list of network ids>" parameter can
now be used to specify a list of network ids that have scan_ssid=1 to
indicate active scanning of the SSID. This adds the listed SSIDs to the
scan command to allow manual scan requests to perform active scans for
hidden SSIDs. For example, "SCAN scan_id=1,7,11" would run a scan with
the SSID fetched from the configured network blocks 1, 7, and 11
(assuming those are set with scan_ssid=1). The SSIDs will be included
even from network blocks that are currently disabled.
The maximum number of SSIDs added to the request is limited by the

When the number of frequencies supported by the kernel is bigger than
one, and there is a need to pick a frequency for a new flow such as P2P
GO Negotiation or P2P Invitation, the flow should be able to pick the
best frequency among all the frequencies currently used by the device.
In order to prioritize between the currently used frequencies, add
the ability to collect additional data about each used frequency
(if the frequency is used by a station interface or P2P Client)
and when needed select the best frequency, where:
1. Infrastructure interfaces have highest priority
2. P2P Client interfaces have higher priority over AP/GO
interfaces.
The rational is that the frequency of an AP/GO can change while
that of a station interface cannot.

This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.
The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:
ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100
DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.

When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)

It is possible for the GO of a persistent group to change the PSK or

up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.
Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to

Scanning can delay concurrent operations considerably, so it is better
to avoid that while trying to connect on any of the virtual interfaces
that share the same radio.

There may be cases where multiple BSS entries for a single BSSID are in
the table. This is mostly in automated test cases due to the AP
configuration changes, but something similar could potentially happen as
a corner case in more realistic networks, too, e.g., when an AP changes
its operating channel. Make network selection more robust by trying to
find the exact BSS entry instead of any BSS entry with a matching BSSID
when storing GAS/ANQP response.

Some extended capabilities (I'm currently interested in "Operating Mode
Notification" for VHT) are implemented by the kernel driver and exported
in nl80211. Use these in hostapd/wpa_supplicant.

If WPS provisioning step is completed with an AP that is in WPS
configured state, we can skip a second scan after the provisioning step
since the AP is unlikely to change its configuration in such a case.
This can speed up WPS connection a bit by removing an unneeded scan.

This can be used to configure wpa_supplicant to ignore old scan results
from the driver cache in cases where such results were not updated after
the scan trigger from wpa_supplicant. This can be useful in some cases
where the driver may cache information for a significant time and the AP
configuration is changing. Many such cases are for testing scripts, but
this could potentially be useful for some WPS use cases, too.

If a peer replies to persistent group invitation with status code 8
(unknown group), remove the peer from the p2p_client_list if we are the
GO or remove the persistent group if we are the P2P client since it
looks like that the peer has dropped persistent group credentials and
the provisioning step needs to be executed again.

Add support for VHT capability overrides to allow testing connections
with a subset of the VHT capabilities that are actually supported by
the device. The only thing that isn't currently supported (by mac80211
and this code) is the RX/TX highest rate field.

Addition of wpa_supplicant_fast_associate() made it unnecessary to call
wpas_select_network_from_last_scan() directly from other files.

If scan results are available when we perform a SelectNetwork, use
them to make an associate decision. This can save an entire scan
interval-worth of time in situations where something external to
wpa_supplicant (like a connection manager) has just previously
requested a scan before calling SelectNetwork.

hostapd.conf sae_groups parameter can now be used to limit the set of
groups that the AP allows for SAE. Similarly, sae_groups parameter is
wpa_supplicant.conf can be used to set the preferred order of groups. By
default, all implemented groups are enabled.

hostapd can now be configured to use anti-clogging mechanism based on
the new sae_anti_clogging_threshold parameter (which is
dot11RSNASAEAntiCloggingThreshold in the standard). The token is
generated using a temporary key and the peer station's MAC address.
wpa_supplicant will re-try SAE authentication with the token included if
commit message is rejected with a token request.

This was used to select between "(auth)" and "(reauth)" in
CTRL-EVENT-CONNECTED events. However, the variable was not cleared
anywhere else apart from the AP deinit case. As such, it did not really
provide correct information and is not really of much use even with
proper clearing added. As such, it is cleaner to just get rid of this
altogether.

Commit 1ff733383f added a mechanism to
work around issues due to association events and EAPOL RX events being
getting reordered. However, this applied only for the case where
wpa_supplicant is not in associated state. The same issue can happen in
roaming case with drivers that perform BSS selection internally (or in
firmware). Handle that case similarly by delaying received EAPOL frame
processing if the source address of the EAPOL frame does not match the
current BSSID.
Since wired IEEE 802.1X do not have BSSID, make this additional
workaround conditional on BSSID match having been observed during the
previous association.
This fixes issues where the initial EAPOL frame after reassociation was
either dropped (e.g., due to replay counter not increasing) or replied
to with incorrect destination address (the BSSID of the old AP). This
can result in significantly more robust roaming behavior with drivers
that do not use wpa_supplicant for BSS selection.
