4bd1efe073 dbus: Do not bring down primary interface when removing created AP interface
If the CreateInterface command was used to create a virtual AP
interface, deleting this interface using the RemoveInterface command was
also bringing down the primary interface.

wpa_supplicant never uses hostapd style multi-BSS setup with
type=WPA_IF_AP_BSS and setup_ap=1 to if_add() when creating an AP
interface in wpa_driver_nl80211_if_add(), so it should not go through
the multi-BSS tear down procedure in wpa_driver_nl80211_if_remove(). The
virtual AP resources init and deinit are well handled in
wpa_driver_nl80211_init() and wpa_driver_nl80211_deinit().

Collapse the interface type to WPA_IF_STATION for the D-Bus interface to
skip the multi-BSS cleanup procedure. This is inline with the control
interface design. Add comments before the code to avoid confusion.

1897abad94 dbus: Add D-Bus property for current MAC address
Since wpa_supplicant can change MAC address of the interface on its own
(with randomization enabled) it makes sense to introduce MACAddress as a
property of the interface and send notifications about its change.

This allows other applications to just use D-Bus instead of both
communicating over D-Bus with wpa_supplicant and listening to Netlink
notifications for MAC changes.

9025def55c wpa_supplicant: Add support for pregenerated MAC
Add new 'mac_addr' policy (3) with which supplicant expects to also
obtain 'mac_value' with pregenerated value of MAC address to be used for
given SSID.

The main difference between this policy and policy 1 is the ability to
control persistence of the MAC address used.  For example if there is
a requirement to always use the same (but random) MAC address for given
SSID (even if user removes/forgets the network) this could be handled
outside of the wpa_supplicant by using some SSID based hashing scheme to
generate MAC (or by just storing the randomly generated one) and
providing it to wpa_supplicant together with mac_addr=3 policy.

5b093570dc D-Bus: Add 'wep_disabled' capability
Since commit 200c7693c9 ('Make WEP functionality an optional build
parameter'), WEP support is optional and, indeed, off by default.

The distributions are now catching up and disabling WEP in their builds.
Unfortunately, there's no indication prior to an attempt to connect to a
WEP network that it's not going to work. Add a capability to communicate
that.

Unlike other capabilities, this one is negative. That is, it indicates
lack of a WEP support as opposed to its presence. This is necessary
because historically there has been no capability to indicate presence
of WEP support and therefore NetworkManager (and probably others) just
assumes it's there.

3a157fe92f dbus: Set CurrentAuthMode to INACTIVE only if network is not selected
CurrentAuthMode should be set as a real auth type when authentication is
in progress. wpa_supplicant has a property "State" which indicates the
authentication stage already. I think setting auth mode as "INACTIVE" in
all auth progress stages is not a good idea, because sometimes we need
to handle this connection according to the auth type even when
authentication is not complete. For example, NetworkManager may recall
ask-password-dialog when auth mode is "wpa-psk" and "sae", try next
access point when auth mode is "EAP-xx" when password is incorrect.
Since "CurrentAuthMode" is set as "INACTIVE" in all not fully completed
situations, we do not know how to handle it.

5ac977758d Reject authentication start during explicit roam requests
The roam D-Bus and ROAM control itnerface commands flip the reassociate
bit before calling wpa_supplicant_connect(). wpa_supplicant connect
eventually aborts ongoing scans (if any), which causes scan results to
be reported. Since the reassociate bit is set, this will trigger a
connection attempt based on the aborted scan's scan results and cancel
the initial connetion request. This often causes wpa_supplicant to
reassociate to the same AP it is currently associated to instead of the
explicitly requested roaming target.

Add a roam_in_progress flag to indicate that we're currently attempting
to roam via an explicitly request to a specific BSS so that we don't
initiate another connection attempt based on the possibly received scan
results from a scan that was in progress at the time the roam command
was received.
