ICMP responses are generated from BH's. hmm, i was thinking about tcp process context, but you're right it can only generate icmps for dead ports and that happens while still in tcp_v4_rcv(). at least ipip.c will send icmps from process context (ipip_tunnel_xmit) netfilter will probably do too. -Andi - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
