d36c803c69 EAP-TLS/PEAP/TTLS/FAST: Move more towards using struct wpabuf
The EAP-TLS-based helper functions can easily use struct wpabuf in more
places, so continue cleanup in that direction by replacing separate
pointer and length arguments with a single struct wpabuf argument.

5aeebc48e8 D-Bus Fix network_is_persistent_group() for P2P operations
Commit c2762e410f ('P2P: Update D-Bus
network object semantics during group formation') added this helper
function to determine whether a network block is used for storing a
persistent group information. However, it implemented this in a way that
matches both persistent group storage and an operating persist group
instance. This does not seem to match the expected behavior for the
D-Bus objects, so fix this to match only the persistent group storage
case to avoid registering/unregistered incorrect D-Bus objects for
groups.

8a78e227df D-Bus: Fix operations when P2P management interface is used
Commit 21efc940f6 ('wpa_supplicant: Do not
register a P2P management interface on DBus') hides the special P2P
management interface from D-Bus. However, it did not take into account
the possibility of wpa_s->dbus_path and wpa_s->dbus_new_path being NULL
in such cases on number of code paths within the D-Bus handlers. This
could result in invalid arguments (NULL path) being provided to D-Bus
functions (mainly, dbus_message_iter_append_basic) and NULL pointer
dereference when iterating over all interfaces. Either of these could
make wpa_supplicant process terminate.

Fix this by explicitly checking that the interface-specific D-Bus path
has been registered before using it anywhere with D-Bus handlers. In
addition, find the correct wpa_s instance to fix P2P operations through
D-Bus when the P2P Device interface is used.

dea0d8ee29 RADIUS: Fix a copy-paste error in variable name

function argument (send_key_len; should be recv_key_len) when allocating

a0ad9e8c9e Remove WPA per-VLAN groups when no more stations remain
Previously, struct wpa_group was created when the first station enters
the group and the struct wpa_group was not freed when all station left
the group. This causes a problem because wpa_group will enter
FATAL_FAILURE when a wpa_group is running while the AP_VLAN interface
has already been removed.

Fix this by adding a reference counter to struct wpa_group and free a
group if it is unused.

5add410162 WPS: Use shorter authentication timeout during no-SelReg iteration
When iterating through WPS APs that do not advertise Selected Registrar
TRUE, limit the authentication timeout to 10 seconds instead of the full
70 second value used with IEEE 802.1X/EAP/WPS in general. This helps
speed up AP iteration for cases where a selected AP misbehaves and does
not reply to EAP exchanges. This should not really be needed, but there
seems to be deployed APs that do not implement WPS correctly and with
such APs in the radio range, this extra timeout can speed up the
iteration to allow the correct AP to be found before the WPS operation
times out.

e7d20342b5 WPS: Enforce five second minimum time before AP iteration
Previously, wpa_supplicant was using number of scan iterations
(WPS_PIN_SCAN_IGNORE_SEL_REG = 3) to give some time for finding a WPS AP
with Selected Registrar TRUE before starting to iterate through all WPS
APs. While this works fine in most cases, some drivers may return the
initial three scan results so quickly that the total amount of time is
only couple of seconds in case none of the APs are initially advertising
Selected Registrar TRUE. To give some more time for APs (WPS Registrars)
to become ready, add an additional constraint on the iteration based on
time (WPS_PIN_TIME_IGNORE_SEL_REG = 5 seconds).
