Functions

func DecideOnCommunication

func DecideOnCommunication(comm *network.Communication, pkt packet.Packet)

DecideOnCommunication makes a decision about a communication with its first packet.

func DecideOnCommunicationAfterIntel

func DecideOnCommunicationAfterIntel(comm *network.Communication, fqdn string, rrCache *intel.RRCache)

DecideOnCommunicationAfterIntel makes a decision about a communication after the dns query is resolved and intel is gathered.

func DecideOnCommunicationBeforeIntel

func DecideOnCommunicationBeforeIntel(comm *network.Communication, fqdn string)

DecideOnCommunicationBeforeIntel makes a decision about a communication before the dns query is resolved and intel is gathered.

func DecideOnLink

func DecideOnLink(comm *network.Communication, link *network.Link, pkt packet.Packet)

DecideOnLink makes a decision about a link with the first packet.

func FilterDNSResponse

func FilterDNSResponse(comm *network.Communication, fqdn string, rrCache *intel.RRCache) *intel.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.
