The new domain_suffix_match (and domain_suffix_match2 for Phase 2
EAP-TLS) can now be used to specify an additional constraint for the
server certificate domain name. If set, one of the dNSName values (or if
no dNSName is present, one of the commonName values) in the certificate
must have a suffix match with the specified value. Suffix match is done
based on full domain name labels, i.e., "example.com" matches
"test.example.com" but not "test-example.com".

When hostapd receives an auth frame during ACS the transmission of
the according auth response will always fail:
ACS: Automatic channel selection started, this may take a bit
[..]
send_auth_reply: send: Resource temporarily unavailable
[..]
However, a station info entry was created. Once ACS is finished
it will flush all stations even though hapd was not yet fully
initialized. This results in a segfault when trying to access
hapd->radius:
0 0x0042c1c0 in radius_client_flush_auth ()
1 0x00416a94 in ap_free_sta ()
2 0x00416cc0 in hostapd_free_stas ()

Fix this by not presuming anything about the initialization state of

Thus a new explicit request would fail an ongoing TDLS negotiation with

printf_decode() fills in a binary buffer and returns the length of
the written data. This did not use null termination since initial
use cases used the output as a binary value. However, Hotspot 2.0
cred block values are also using this for parsing strings. Those
cases could end up without proper null termination depending on what
os_malloc() ends up getting as the memory buffer. Fix these and make
printf_decode() more convenient by forcing the output buffer to be
null terminated.

When no other user preference is specified, opt to use an operating

Some APs may incorrectly change Device Password ID from PBC in M1 to
Default PIN in M2 even when they are ready to continue with PBC. This
behavior used to work with earlier implementation in wpa_supplicant, but
commit b4a17a6ea7 started validating this
as part of a change that is needed to support NFC configuration method.
While this kind of AP behavior is against the WSC specification and
there could be potential use cases for moving from PBC to PIN, e.g., in
case of PBC session overlap, it is justifiable to work around this issue
to avoid interoperability issues with deployed APs. There are no known
implementations of PBC-to-PIN change from M1 to M2, so this should not
reduce available functionality in practice.

It is possible for the GO of a persistent group to change the PSK or
remove a client when per-client PSKs are used and this can happen
without the SSID changing (i.e., the group is still valid, but just not
for a specific client). If the client side of such persistent group ends
up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.
Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to
indicate when this happens. This makes it easier for upper layers to
remove the persistent group information with "REMOVE_NETWORK <persistent
group id>" if desired (e.g., based on user confirmation).
In addition to indicating the error cases for persistent groups, all
this type of PSK failures end up in the client removing the group with
the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

The new control interface command P2P_REMOVE_CLIENT <P2P Device

"wpa_cli p2p_set per_sta_psk <0/1>" can now be used to disable/enable
use of per-device PSKs in P2P groups. This is disabled by default.
When enabled, a default passphrase is still generated by the GO for
legacy stations, but all P2P and non-P2P devices using WPS will get
a unique PSK.
This gives more protection for the P2P group by preventing clients from
being able to derive the unicast keys used by other clients. This is
also a step towards allowing specific clients to be removed from a group
reliably without having to tear down the full group to do so.
