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.
WPS external Registrars can get confused about multiple UPnP
instances (one per radio) on a dual-concurrent APs. Simplify the
design by sharing a single UPnP state machine for all wireless
interfaces controlled by hostapd. This matches with the previous
changes that made a single command enable WPS functionality on
all interfaces.
This is relatively minimal change to address the sharing of the
state among multiple struct hostapd_data instances. More cleanup
can be done separately to remove unnecessary copies of information.
When hostapd_cli deauth/disassoc is used with ff:ff:ff:ff:ff:ff
address, drop all local STA entries in addition to sending out the
broadcast deauth/disassoc frame.
When the peer does not include our initial preference in the Channel
List attribute during GO Negotiation, try to use the best channel of
the other band as the new preference instead of falling back to the
first channel in the intersection.
