- OS custom internal package for file system interaction
- Remove fileManager external dependency
- Closer API to Go's native API on the OS
- Create directories at startup
- Better testability
- Move Unsetenv to os interface
- From now only a single OpenVPN connection is written to the OpenVPN configuration file
- If multiple connections are matched given the user parameters (i.e. city, region), it is picked at pseudo random using the current time as the pseudo random seed.
- Not relying on Openvpn picking a random remote address, may refer to #229
- Program is aware of which connection is to be used, in order to use its matching CN for port forwarding TLS verification with PIA v4 servers, see #236
- Simplified firewall mechanisms
- Only a map of allowed input port to interface
- port forwarded is in the map of allowed input ports
- port forwarded has the interface tun0 in this map
- Always allow tcp and udp for allowed input ports
- Port forward state is in openvpn looper only
- Shadowsocks input port allowed on default interface only
- Tinyproxy input port allowed on default interface only
- Ability to enable and disable rules in various loops
- Simplified code overall
- Port forwarding moved into openvpn loop
- Route addition and removal improved
- 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 ...`
Additional changes:
- Allow empty value for PIA region
- Most settings are lowercased
- `OPENVPN_VERBOSITY` environment variable
- openvpn also tunnels IPv6, and unbound supports ipv6
- auth kept only on disk, not in memory
- readme reworked
- CI script fixed and improved
- Added v2 Docker tag
- Shadowsocks log defaults to `off`
- 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)
