Functions

func DecideOnConnection

func DecideOnConnection(conn *network.Connection, pkt packet.Packet)

DecideOnConnection makes a decision about a connection. When called, the connection and profile is already locked.

func FilterDNSResponse

func FilterDNSResponse(conn *network.Connection, q *resolver.Query, rrCache *resolver.RRCache) *resolver.RRCache

FilterDNSResponse filters a dns response according to the application profile and settings.

func GetPermittedPort

func GetPermittedPort() uint16

GetPermittedPort returns a local port number that is already permitted for communication. This bypasses the process attribution step to guarantee connectivity. Communication on the returned port is attributed to the Portmaster.

func PermittedAddr

func PermittedAddr(network string) net.Addr

PermittedAddr returns an already permitted local address for the given network for reliable connectivity. Returns nil in case of error.

func PermittedTCPAddr

func PermittedTCPAddr() *net.TCPAddr

PermittedTCPAddr returns an already permitted local tcp address for reliable connectivity. Returns nil in case of error.

func PermittedUDPAddr

func PermittedUDPAddr() *net.UDPAddr

PermittedUDPAddr returns an already permitted local udp address for reliable connectivity. Returns nil in case of error.
