Reject external scan request while either ANQP fetch or Interworking
select is in progress. Not doing so could lead to a situation in which
Interworking automatic network selection does not get triggered because
of a new scan result event forcing the ANQP fetch cycle to be disrupted
and restarted all over again. Interworking automatic network selection
is only triggered when AQNP fetch cycle, that is, ANQP exchange with
every Interworking capable BSS in the current BSS list, is completed.

wpa_supplicant_deinit_iface() ends up removing all P2P groups if the
removed interface is the parent interface. This is correct behavior in
general, but this resulted in issues in the new group interface
initialization error path since wpa_s->parent was not assigned before
hitting this check. Fix this by assigning wpa_s->parent as part of

This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.
INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other

when running hwsim test cases, but at least in theory, this could happen
with real use cases as well). When that happened, the incorrect BSS
entry may not have included RSN configuration and as such, it would get
rejected for Interworking connection.

not, try to find another BSS entry matching the same BSSID and use that,

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.
