hi
I know some ICMP errors are only returned if datagram that caused it is of UDP type(ICMP port unreachable).
But what ICMP errors do get returned to TPC sockets?
When TCP socket in an already established connection specifies SSRR and one of routers can't forward datagram to the next hop,does it return ICMP source route error to this socket?If so,is this ICMP packet silently discarded by the kernel and not returned to socket?
thank you
