* migrate to golang.zx2c4.com/wireguard/wgctrl This commit introduces the usage of wgctrl. It avoids the usage of exec calls of the wg command and parsing the output of `wg show`. Signed-off-by: leonnicolas <leonloechner@gmx.de> * vendor wgctrl Signed-off-by: leonnicolas <leonloechner@gmx.de> * apply suggestions from code review Remove wireguard.Enpoint struct and use net.UDPAddr for the resolved endpoint and addr string (dnsanme:port) if a DN was supplied. Signed-off-by: leonnicolas <leonloechner@gmx.de> * pkg/*: use wireguard.Enpoint This commit introduces the wireguard.Enpoint struct. It encapsulates a DN name with port and a net.UPDAddr. The fields are private and only accessible over exported Methods to avoid accidental modification. Also iptables.GetProtocol is improved to avoid ipv4 rules being applied by `ip6tables`.
