In order to avoid chaos from multiple profiles, retain the
profile to be installed and remove all the other ones. Also,
make sure to do the removal AFTER install, as doing it
before would trigger the VPN permission alert again.
XXX: there is some weird behavior from NetworkExtension
occasionally sending notifications with a bogus NEVPNManager
object having a nil .localizedDescription and other properties set
to nonsensical values. Discard the notification when such an object
is identified.
Encapsulate extra NetworkExtension settings:
- passwordReference
- onDemandRules
- disconnectsOnSleep
Also:
- Only set on-demand if any rules are set
- Assume VPN is enabled even with on-demand disabled
- Use DataCount instead of raw Int pair
Attach useful information to VPN notifications:
- VPN isEnabled
- VPN status
- VPN command error
- Tunnel bundle identifier (if available)
Expose specific OpenVPN/WireGuard shared data via extensions in
UserDefaults/FileManager.
Finally, drop incomplete IKE support. No fit.
Minimize target dependency on OpenSSL (easier to drop later).
Outside of OpenVPN tunnel extension, OpenSSL is only used to
decrypt encrypted private keys in CryptoContainer (found in
TunnelKitOpenVPNCore, therefore "temporarily" dependent on
CTunnelKitOpenVPNAppExtension for TLSBox/CryptoBox).
