p2p groups created under wrong interface via dbus?

[viktor babrian <viktor.babrian@xxxxxxxxx>]

Hi,

short form: groups (either persistent or not) are added to an
assumedly wrong interface if issued via dbus. if done via control
interface, groups are added as expected.

I have a test setup of 3 mac80211_hwsim radios (wlan0-2). In this
scenario I use wlan0 and wlan2. Mesh0 is added to wlan0 with the
command "iw phy phy1 interface add mesh1 type mp". wpa_cli reports:
> interface
Available interfaces:
wlan2
wlan0
p2p-dev-mesh0
mesh0

Mesh0 network:
network={
    ssid="meshssid"
    mode=5
    frequency=2437
    key_mgmt=SAE
    psk="meshpassword"
}

Case 1: using wpa_cli: I select interface wlan0 and create a group via
p2p_group_add. Group appears in wlan0 network list. Scanning using
wlan2 shows both the mesh network and the newly created group.

Case 2. using dbus. I get object path for interface wlan0 via
"GetInterface" (resulting in /fi/w1/wpa_supplicant1/Interfaces/3). I
issue a GroupAdd or ADDPersistentGroup. wpa_cli reports the groups
under mesh0. Debug output confirms:
dbus: fi.w1.wpa_supplicant1.Interface.P2PDevice.AddPersistentGroup
(/fi/w1/wpa_supplicant1/Interfaces/3) [a{sv}]
dbus: Register persistent group object
'/fi/w1/wpa_supplicant1/Interfaces/1/PersistentGroups/1'
[...]
dbus: fi.w1.wpa_supplicant1.Interface.P2PDevice.GroupAdd
(/fi/w1/wpa_supplicant1/Interfaces/3) [a{sv}]
wpa_dbus_dict_open_read: start reading a dict entry
dbus: Register group object '/fi/w1/wpa_supplicant1/Interfaces/1/Groups/wL'

Groups are added under /fi/w1/wpa_supplicant1/Interfaces/.

Is it intended so? I see that control interface and dbus handlers are
completely different.

Any help is welcome,
Thanks,
Viktor
