Past this commit I get corruptions after 5 minutes at most (that's ADSL with USB Thomson/Alcatel Speedtouch -> PPP over ATM, with a GRE tunnel over that PPP). I'm now running 901eaf6c8f997f18ebc8fcbb85411c79161ab3b2 (i.e. the last commit before the one in question) for 4 hours and nothing like that. Not sure about the exact rule, but the most probable candidates are: -A INPUT -p tcp --tcp-flags SYN,RST,ACK SYN -j REJECT --reject-with tcp-reset -A INPUT -p udp -j REJECT --reject-with icmp-port-unreachable Other "REJECT" rules haven't fired yet. Could be some obscure problem with GRE/Speedtouch/PPP over ATM, triggered by this patch, though. Perhaps I can do some experiments - just say a word. -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
