[android] Device protected vs. user-credential protected storage, no tunnels before first unlock on modern Android?

[android] Device protected vs. user-credential protected storage, no tunnels before first unlock on modern Android?

[Karaahmetoglu, Ahmet]

Dear WireGuard community,

It seems that for accessing tunnel configurations the different components of wireguard-android only support accessing the user-credential protected storage (/data/data/). This path is usually not available before first unlock on modern Android, so WireGuard is not able to access its configuration.

I was wondering if this in on purpose or are there any plans on adding support for device protected storage (/data/data_de/)? Actually, I would assume that storing tunnel configurations there is essential for always_on_vpn_lockdown to be working - which seems to be supported by WireGuard when looking at Android VPN settings. But this can hardly be the case - if I'm not mistaken.

So, any hints/background information about the situation is highly appreciated.

Thank you very much in advance, and kind regards,
Ahmet Karaahmetoglu
