migrate to golang.zx2c4.com/wireguard/wgctrl (#239) * 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`. Signed-off-by: leonnicolas <leonloechner@gmx.de> * pkg/wireguard/conf_test.go: add tests for Endpoint Signed-off-by: leonnicolas <leonloechner@gmx.de> * cmd/kg/main.go: validate port range Signed-off-by: leonnicolas <leonloechner@gmx.de> * add suggestions from review Signed-off-by: leonnicolas <leonloechner@gmx.de> * pkg/mesh/mesh.go: use Equal func Implement an Equal func for Enpoint and use it instead of comparing strings. Signed-off-by: leonnicolas <leonloechner@gmx.de> * cmd/kgctl/main.go: check port range Signed-off-by: leonnicolas <leonloechner@gmx.de> * vendor Signed-off-by: leonnicolas <leonloechner@gmx.de>
