    tipc: Ensure network address change doesn't impact local connections · f0712e86
    Allan Stephens authored
    Revises routines that deal with connections between two ports on
    the same node to ensure the connection is not impacted if the node's
    network address is changed in mid-operation. The routines now treat
    the default node address of <0.0.0> as an alias for "this node" in
    the following situations:
    
    1) Incoming messages destined to a connected port now handle the alias
    properly when validating that the message was sent by the expected
    peer port, ensuring that the message will be accepted regardless of
    whether it specifies the node's old network address or it's current one.
    
    2) The code which completes connection establishment now handles the
    alias properly when determining if the peer port is on the same node
    as the connected port.
    
    An added benefit of addressing issue 1) is that some peer port
    validation code has been relocated to TIPC's socket subsystem, which
    means that validation is no longer done twice when a message is
    sent to a non-socket port (such as TIPC's configuration service or
    network topology service).
