Functions ¶

func ARP ¶

func ARP(pkt *stack.PacketBuffer) bool

ARP populates pkt's network header with an ARP header found in pkt.Data.

Returns true if the header was successfully parsed.

func ICMPv4 ¶

func ICMPv4(pkt *stack.PacketBuffer) bool

ICMPv4 populates the packet buffer's transport header with an ICMPv4 header, if present.

Returns true if an ICMPv4 header was successfully parsed.

func ICMPv6 ¶

func ICMPv6(pkt *stack.PacketBuffer) bool

ICMPv6 populates the packet buffer's transport header with an ICMPv4 header, if present.

Returns true if an ICMPv6 header was successfully parsed.

func IPv4 ¶

func IPv4(pkt *stack.PacketBuffer) bool

IPv4 parses an IPv4 packet found in pkt.Data and populates pkt's network header with the IPv4 header.

Returns true if the header was successfully parsed.

func IPv6 ¶

func IPv6(pkt *stack.PacketBuffer) (proto tcpip.TransportProtocolNumber, fragID uint32, fragOffset uint16, fragMore bool, ok bool)

IPv6 parses an IPv6 packet found in pkt.Data and populates pkt's network header with the IPv6 header.

func TCP ¶

func TCP(pkt *stack.PacketBuffer) bool

TCP parses a TCP packet found in pkt.Data and populates pkt's transport header with the TCP header.

Returns true if the header was successfully parsed.

func UDP ¶

func UDP(pkt *stack.PacketBuffer) bool

UDP parses a UDP packet found in pkt.Data and populates pkt's transport header with the UDP header.

Returns true if the header was successfully parsed.
