76fe79ef2d Register wpa_msg callback even if only global ctrl_iface is used
Previously, wpa_msg_register_cb() was called only from successful
completion of per-interface control interface initialization. This would
leave the callback unregistered in case only the global control
interface is used which would result in not delivering control interface
events on the global interface. Fix this by registering the callback
handler also from successful initialization of the global control
interface.

5d4c78fb1f nl80211: Reset nlmode to station on leaving IBSS
Previously, IBSS mode (NL80211_IFTYPE_ADHOC) was left in drv->nlmode
when leaving IBSS. This causes issues for send_mlme() handler for P2P
Probe Response transmission in Listen state. Fix this by clearing nlmode
back to NL80211_IFTYPE_STATION on leaving IBSS so that following P2P
operations can be executed correctly. Previously, this was fixed only
when the next authentication/association attempt in station mode
occured.

ed1bf011da Allow hostapd config file for dynamically added interface
This extends hostapd global control interface command "ADD" to use a
configuration file instead of requiring configuration to be built using
SET command.

The command format is now following:
ADD <ifname> <control path|config=<path to config>>

For example:

ADD wlan0 /var/run/hostapd
ADD wlan0 config=/tmp/hostapd.conf

When using the configuration file option, ctrl_interface parameter in
the file needs to be set to allow ENABLE command to be issued on the new
interface.

89286e91bf Re-open ctrl_iface socket on some failure cases as a workaround
If wpa_supplicant ctrl_iface clients are misbehaving and refusing to
read replies or event messages from wpa_supplicant, the single socket
used in wpa_supplicant to send messages can reach the maximum send
buffer limit. When that happens, no more responses to any client can be
sent. Work around this by closed and reopening the socket in case such a
failure state is detected. This is obviously not desirable since it
breaks existing connected sockets, but is needed to avoid leaving
wpa_supplicant completely unable to respond to any client. Cleaner fix
for this may require more considerable changes in the ctrl_iface design
to move to connection oriented design to allow each client to be handled
separately and unreachability to be detected more reliably.

913c19c6e5 Fix wpa_config_parse_string() to null terminate printf decoded values
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.

d047ae6278 WPS: Ignore PBC-to-PIN change from M1 to M2 as a workaround
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 was possiblle for the group formation timeout to be left running even
after the P2P Client connected to the group if the WPS provisioning step
was not completed cleanly (e.g., due to WSC_Done not getting received

to the initial group formation timeout, so work around this by removing
that timeout on data connection.

b2b688d18d P2P: Fix crash when failed to create GO interface
wpa_supplicant crashes if driver configuration for AP mode interface
configuration fails after group negotiation. This is because of a
regression from commit 1075b29571 that
ends up freeing the wpa_s instance from within
wpa_supplicant_create_ap() without the caller knowing.

Fix this by using an eloop timeout to free remove the P2P group so that
wpa_supplicant_create_ap() and especially wpa_supplicant_associate()
callers do not need to know about interface getting possibly removed. In
addition, move the P2P specific code into p2p_supplicant.c where it
really belongs. This allows the already existing group formation timeout
to be used by reducing the timeout to zero.

5bf9a6c859 P2P: Add event messages for possible PSK failures on P2P groups
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.

"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.
