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.

a250722f38 Try to set PMK only with key mgmt offload support in the driver
Previously, it was possible for the set_key() handler to be used with
WPA_ALG_PMK even if the driver did not indicate support for key
management offload. While this is not really supposed to result in any
difference, it makes the debug logs somewhat confusing. Avoid that by
using driver capability flag for key management offload as an additional
condition for setting the PMK.

9f390f431c Interworking: Fix network selection warning without SIM/USIM support
interworking_credentials_available_3gpp() would have left excluded2
uninitialized without INTERWORKING_3GPP in the build. This could result
in a static analyzer warning within
interworking_credentials_available_helper() about use of uninitialized
variable. Get rid of that warning by explicitly initializing excluded2
even though this does not really result in any difference in behavior
since the excluded2 value would be used only if the non-NULL is returned
and that could not have been the case here without INTERWORKING_3GPP.

eaa3728a64 wpa_gui: Themed icon loader
Signal strength meter uses non-standard icons (not included in the
freedesktop icon specification), which might not be available in all

Unfortunately not all icon sets provide them.

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).

WPS property of the fi.w1.wpa_supplicant1.BSS interface:

==

Dictionary entries are:

However the implementation returns "type" => "" for BSSes
that do not support WPS.

Fix the implementation to match the documentation.
Return empty dictionary if there is no WPS support.
And "type" => "" if WPS is supported, but is not in progress

a52410c29f Allow PSK/passphrase to be set only when needed
The new network profile parameter mem_only_psk=1 can be used to specify
that the PSK/passphrase for that network is requested over the control
interface (ctrl_iface or D-Bus) similarly to the EAP network parameter
requests. The PSK/passphrase can then be configured temporarily in a way
that prevents it from getting stored to the configuration file.

For example:

Event:
CTRL-REQ-PSK_PASSPHRASE-0:PSK or passphrase needed for SSID test-wpa2-psk

Response:
CTRL-RSP-PSK_PASSPHRASE-0:"qwertyuiop"

Note: The response value uses the same encoding as the psk network
profile parameter, i.e., passphrase is within double quotation marks.

network, or not connected with the wpa_supplicant service), and four for
connected status (showing the signal strength on the receiver).

By default this functionality is disabled. The reason for this, is the
fact, that the underlaying approach of this functionality is poll based,
which might be considered as a non-efficient one. Update interval has to
be set explicitly by the user with '-m<seconds>' command line argument.

Status icon names are based on various Gnome icon packs (e.g., Faba).
When icon can not be found, default one is shown (wpa_gui logo).
