- Goal was to simplify main.go complexity
- Use common structures and interfaces for all vpn providers
- Moved files around
- Removed some alias models
- Fix bad permissions bits for files
- VPNSP is 'private internet access' instead of 'pia' (retro compatible)
- Check errors of deferred unsetEnv functions in params package
- Other lint errors fixing and code simplifications
- Obtains VPN public IP address from routing table
- Logs and writes VPN Public IP address to `/ip` as soon as VPN is up
- Obtain port forward, logs it and writes it as soon as VPN is up
- Routing fully refactored and tested
- Routing reads from `/proc/net/route`
- Routing mutates the routes using `ip route ...`
- Environment variables `UID` and `GID`, both defaulting to `1000`
- All subprocesses (openvpn, tinyproxy, etc.) run using the UID and GID given
- All files are written with an ownership for the UID and GID given
- Port forwarded file has also ownership for UID, GID and read permission only
- General improvements
- Parallel download of only needed files at start
- Prettier console output with all streams merged (openvpn, unbound, shadowsocks etc.)
- Simplified Docker final image
- Faster bootup
- DNS over TLS
- Finer grain blocking at DNS level: malicious, ads and surveillance
- Choose your DNS over TLS providers
- Ability to use multiple DNS over TLS providers for DNS split horizon
- Environment variables for DNS logging
- DNS block lists needed are downloaded and built automatically at start, in parallel
- PIA
- A random region is selected if the REGION parameter is left empty (thanks @rorph for your PR)
- Routing and iptables adjusted so it can work as a Kubernetes pod sidecar (thanks @rorph for your PR)
