The duplicated WPS event in the parent interface should only be used
during P2P group formation, i.e., when the WPS operation was actually
started using the parent interface. When authorizing a client to
connect to an already running group, the WPS command is issued on
the group interface and there is no need to duplicate the event to
the parent interface.
This pointer is now used in number of places to check whether an
interface is in P2P Group Formation, so we better make sure it gets
cleared when group formation has been completed. This was done in
only some of the cases.
ap_setup_locked=2 can now be used to enable a special mode where
WPS ER can learn the current AP settings, but cannot change then.
In other words, the protocol is allowed to continue past M2, but
is stopped at M7 when AP is in this mode. WPS IE does not
advertise AP Setup Locked in this case to avoid interoperability
issues.
In wpa_supplicant, use ap_setup_locked=2 by default. Since the AP PIN
is disabled by default, this does not enable any new functionality
automatically. To allow the read-only ER to go through the protocol,
wps_ap_pin command needs to be used to enable the AP PIN.
The pending_invite_ssid_id of -1 (running group, not persistent) was
being stored incorrectly in the group interface, not device interface
(i.e., parent of the group interface) and consequently, the incorrect
information was used when processing the Invitation Response.
If there was a persistent group credentials stored with network id
0, those were used instead to try to set up a persistent group
instead of using the already running group.
Since the P2P peer entry may not have been available at the time the
join request was issued, we need to allow the P2P Interface Address
to be updated during join-scans when the P2P peer entry for the GO
may be added.
If the GO is not found, we cannot send Provisioning Discovery Request
frame and cannot really connect anyway. Since the Provisioning
Discovery is a mandatory part, it is better to continue join-scan
until the GO is found instead of moving to the next step where
normal connection scan is used (PD would not be used from there).
Use a limit of 10 scan attempts for p2p_connect join to avoid getting
in infinite loop trying to join. If the GO is not found with those
scans, indicate failure (P2P-GROUP-FORMATION-FAILURE) and stop the
join attempt.
CONFIG_WPA_CLI_EDIT=y can now be used to build wpa_cli with internal
implementation of line editing and history support. This can be used
as a replacement for CONFIG_READLINE=y.
Instead of using a separate process to receive and print event
messages, use a single-process design with eloop to simply
wpa_cli and interaction with readline.
Instead of multiple #ifdef blocks for readline within the function,
use two copies of the functions, one for readline, one without any
readline functionality.
Verify that WPA/RSN IE in (Re)Association Request is identical to the
one used in EAPOL-Key message 2/4.
Verify that WPA/RSN IE in Beacon/Probe Response is identical to the
one(s) used in EAPOL-Key message 3/4.
There is no point in maintaining two almost identical versions
of this parser. Move WPA IE parser into wpa_common.c similarly
to what was already the case with RSN IE parse.
When running "p2p_connect addr pbc join" command, send the
WPS-OVERLAP-DETECTED even also to the parent interface (i.e.,
the one on which the p2p_connect was issued) and not only the
group interface in case separate P2P group interfaces are used.
The output file includes all the capture (or read from wireless PCAP
file) frames in their original contents and another copy of each
frame that is decrypted in wlantest (including EAPOL-Key Key Data
field).
When multiple wireless interfaces are used with WPS, the UPnP
subscriptions need to be removed whenever a matching Registrar
instance gets removed. This avoids a segfault due to access to
freed memory during hostapd shutdown.
In addition, the UPnP interface instance structure needs to be
freed to avoid memory leak.
