In 2.6.8.1 af_packet.c the logic in create and bind wastes cycles. When you create a socket it calls create which sets the socket state on po-> to "running". Then when bind is first called it checks this "running" flag, unbinds the previous state created with "create" frees the sk and prot hook structures sets the state to running=0 then resets the state again to running=1 and reallocates these structures. This seems to waste some cycles. caught this since I hook create, bind, and unbind in af_packet for our software. It looks like the logic in the sockets layer above causes this behavior.
Is there a reason it should act this way. Seems wasteful of cycles since most peoples just call create, bind, send send rcv rcv rcv send send, unbind
