d40788a5cb P2P: Use specified frequency for group client in P2P_GROUP_ADD command
In P2P_GROUP_ADD command and GroupAdd dbus method, frequency is passed

operating frequency determined out of band. Use this pre-determined
frequency in P2P client as well to expedite the P2P scan.

aa2dfae5eb dbus: Fix memory leak with Bonjour params for a P2P UPnP service
Using D-Bus, it is possible to add a valid UPnP service where 'query'
and 'response' are specified. In this case, memory for 'query' and
'response' is allocated but not used nor freed. Valgrind complains as

However, the p2p_6ghz_disable parameter in the configuration takes a

996662250d P2P: Add support for EDMG channels
This allows a P2P connection over P802.11ay EDMG channels to achieve the
highest link speed that the standard allows for channel bonding (CB) up
to CB4.

Let each P2P peer add its EDMG channels to the Supported Channels IE
advertised in P2P GO negotiation. Give EDMG channels priority when peers
negotiate for operating channel.

User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.

When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz
channel.

b2ad4e6b24 D-Bus: Fix P2P NULL dereference after interface removal
When the P2P management interface is deleted, P2P is then disabled and
global->p2p_init_wpa_s is set to NULL. After that, other interfaces can
still trigger P2P functions (like wpas_p2p_find()) using D-Bus. This
makes wpa_supplicant terminate with SIGSEGV, because it dereferences a
NULL pointer. Fix this by adding proper checks, like it's done with
wpa_cli.

dfaf11d648 P2P: Require fresh scan results for persistent group re-invocation
The P2P group is not yet operating when going through invitation
exchange for re-invocation. Previously, an old cached scan result could
be used to skip the scan immediately after the invitation exchange.
While this may result in the fastest possible connection, it does have
some issues with cases where the GO takes some time to start up. It
would also be at least theoretically possible for some of the BSS
parameters to be different, so having a fresh scan result from the new
GO instance may be desired in any case.

Add a mechanism to skip scan results that have been last updated before
a specific point in time and as the first user for this mechanism,
require chan results to be more recent than the invitation message
exchange for the P2P Client role in persistent group re-invocation case.

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.

fa9f381f20 P2P: Allow a specific channel to be specified in P2P_FIND
The optional freq=<MHz> can now be used with the P2P_FIND command to
specify a single channel to scan during the first round of P2P search.
For example, this can be used to replace the full initial scan with a
single channel scan of a known operation channel.

6d9085145c P2PS: Process P2PS provisioning commands
This extends wpas_p2p_prov_disc() implementation to accept P2PS
parameters. None of the callers are yet using this functionality; the
following commit introduces a user.

5177509657 P2PS: Add option to specify seek strings into P2P_FIND
P2PS seek strings can now be specified in the P2P_FIND control interface
command with one or more optional "seek=<str>" parameters.

1a4efde5bd D-Bus: Make P2P Group Passphrase property getter available for P2P Client
There is no need to limit this property based on the role of the device
in the group, so return the passphrase if it is available. It will be
available in GO role and it may be available in P2P Client role based on
whether the peer GO provided it during the WPS provisioning step.

20e1d81e09 D-Bus: Fix P2P Group PSK property getter
This was returning a byte array of the pointer to the PSK, not the
actual PSK, due to incorrect use of
wpas_dbus_simple_array_property_getter(). In addition, there is no need
to limit this property based on the role of the device in the group, so
return the PSK if it is available (which it will be for both GO and P2P
Client roles).

a0caebf397 D-Bus: Simplify out-of-memory reporting
There is no need to have separate wpa_printf() and different error
message strings for the unlikely out-of-error messages. Use a helper
function, wpas_dbus_error_no_memory(), to get consistent behavior with a
one-line call.

e3c4f0b5d5 D-Bus: Simplify message building error paths
There is no need to have multiple separate return statements for error
cases in a sequence of operations. In addition, there is not much point
in "converting" boolean return values with "if (!res) return FALSE;
return TRUE;" style constructions.

bba40b65b0 D-Bus: Fix GroupAdd, Invite, RemovePersistentGroup path validation
net_id_str can be NULL and that must be checked for to avoid NULL
pointer dereference if an invalid persistent_group_object path is used
with these methods.

054dc3136f D-Bus: Clean up wpas_dbus_new_decompose_object_path()
None of the new D-Bus interface cases use the bssid_part in
decompose_object_path (while the old interface ones do). As such, this
is dead code and can be removed. In addition, the P2P addition here was
pretty ugly extension. Replace these with a cleaner way of passing the
separating string (e.g., "Networks") from the caller and returning the
requested item.

In addition, there is no need to allocate the returned item separately,
so use a single allocation and a pointer to that allocated memory. This
will make it easier for callers to have to free only a single
allocation. This is also fixing a memory leak in P2P invitation
persistent group case where the caller had missed the need to free the
returned values.
