ae2b4827cc GAS: Check protected/unprotected drop after action code check
Apply the GAS specific rule of using Protected Dual of Public Action
frame only after having checked that the action code indicates this to
be a GAS response. Previously, non-GAS Public Action frames could have
been incorrectly dropped because of this check if received during an
association with PMF enabled.

The GAS-QUERY-DONE event with result=INTERNAL_ERROR was reported on most
other error cases, but the failure triggered by not being able to
transmit a GAS Initial Request stopped the query silently. Make this
more consistent with other error cases by reporting the same event.

fc1e2c0d91 D-Bus: Make the CurrentAuthMode property getter more robust
Now that mesh sets wpa_s->wpa_state = WPA_COMPLETED, it looks like this
getter can get called with wpa_s->current_ssid = NULL. That could result
in NULL pointer dereference, so need to protect that specific case.

82b9ec3125 D-Bus: Add DeviceFoundProperties signal for discovered peers
This signal sends the peer properties to applications for discovered
peers. The signature of this event is "oa{sv}". This event is needed
because the current DeviceFound signal provides only the peer object
path. If there are many peers in range there will be many DeviceFound
signals and for each DeviceFound signal, applications would need to use
GetAll to fetch peer properties. Doing this many times would create
extra load over application as well as over wpa_supplicant, so it is
better to send peer properties in the event so that applications can
extract found peer information without extra steps.

The existing DeviceFound signal is left as-is to avoid changing its
signature.

The issue is not applicable to the control interface because the
P2P-DEVICE-FOUND event includes peer info in it, but over D-Bus
interface DeviceFound provides only the peer object.

4976618c76 mesh: Mark wpa_state COMPLETED when mesh join has been performed
In mesh interface, the wpa_supplicant state was either
DISCONNECT/SCANNING in non-secured connection or AUTHENTICATING in
secured connection. The latter prevented the scan. Update the
wpa_supplicant state in mesh to be COMPLETED upon initialization. This
is similar to the P2P GO case.

b94fff1d93 wpa_supplicant: Configurable EAP fragment size in AP mode
In wpa_supplicant AP mode, allow configuration of the EAP fragment size
using the fragment_size member of network block (wpa_ssid), similar to
the fragment_size in hostapd configuration. bss->fragment_size default
value of 0 is treated specially in some EAP code paths (such as MTU
initialization in eap_pwd_init). In order to preserve the existing
behavior, bss->fragment_size will only be set if the network block
specified a value different from the default which is
DEFAULT_FRAGMENT_SIZE(1398) bytes.

3b208346ec ctrl_iface: BSS command to skip info items if parsing fails
In some cases parsing of the mesh scan info for a BSS or the P2P scan
info can fail. One reason can be that the Beacon/Probe Response frame
contained malformed length vendor IEs which are not parsed when adding
to the BSS table. Instead of skipping the whole BSS of the BSS command,
just skip the part that failed to parse.

c86bef2913 wpa_supplicant: Make GAS Address3 field selection behavior configurable
IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS.
wpa_supplicant used to use the actual BSSID value for all such frames
regardless of whether the destination STA is a member of the BSS.

P2P does not follow this rule, so P2P Public Action frame construction
must not be changed. However, the cases using GAS/ANQP for non-P2P
purposes should follow the standard requirements.

Unfortunately, there are deployed AP implementations that do not reply
to a GAS request sent using the wildcard BSSID value. The previously
used behavior (Address3 = AP BSSID even when not associated) continues
to be the default, but the IEEE 802.11 standard compliant addressing
behavior can now be configured with gas_address3=1.
