Field
Description
• 3—SOCK_RAW. This socket allows an application to change the next
upper-layer protocol header.
• N/A—None of the above types.
Protocol Number of the protocol using the socket. 6 represents TCP.
Connection info
Connection information, including source IPv6 address and port number,
and destination IPv6 address and port number.
Inpcb flags
Flags in the Internet PCB:
• INP_RECVOPTS—Receives IPv6 options.
• INP_RECVRETOPTS—Receives replied IPv6 options.
• INP_RECVDSTADDR—Receives destination IPv6 address.
• INP_HDRINCL—Provides the entire IPv6 header.
• INP_REUSEADDR—Reuses the IPv6 address.
• INP_REUSEPORT—Reuses the port number.
• INP_ANONPORT—Port number not specified.
• INP_PROTOCOL_PACKET—Identifies a protocol packet.
• INP_RCVVLANID—Receives the VLAN ID of the packet. Only UDP
and RawIP support this flag.
• IN6P_IPV6_V6ONLY—Only supports IPv6 protocol stack.
• IN6P_PKTINFO—Receives the source IPv6 address and input
interface of the packet.
• IN6P_HOPLIMIT—Receives the hop limit.
• IN6P_HOPOPTS—Receives the hop-by-hop options extension
header.
• IN6P_DSTOPTS—Receives the destination options extension header.
• IN6P_RTHDR—Receives the routing extension header.
• IN6P_RTHDRDSTOPTS—Receives the destination options extension
header preceding the routing extension header.
• IN6P_TCLASS—Receives the traffic class of the packet.
• IN6P_AUTOFLOWLABEL—Attaches a flow label automatically.
• IN6P_RFC2292—Uses the API specified in RFC 2292.
• IN6P_MTU—Discovers differences in the MTU size of every link along
a given data path. TCP does not support this flag.
• INP_RCVMACADDR—Receives the MAC address of the frame.
• INP_SYNCPCB—Waits until Internet PCB is synchronized.
• N/A—None of the above flags.
Inpcb vflag
IP version flags in the Internet PCB:
• INP_IPV4—IPv4 protocol.
• INP_IPV6—IPv6 protocol.
• INP_IPV6PROTO—Creates an Internet PCB based on IPv6 protocol.
• INP_TIMEWAIT—In TIMEWAIT state.
• INP_ONESBCAST—Sends broadcast packets.
• INP_DROPPED—Protocol dropped flag.
• INP_SOCKREF—Strong socket reference.
• INP_DONTBLOCK—Do not block synchronization of the Internet PCB.
• N/A—None of the above flags.
Hop limit(minimum hop limit)
Hop limit in the Internet PCB. The minimum number of hops is in the
parentheses.
Connection state
TCP connection state:
• CLOSED—The server receives a disconnection request's reply from
the client.
