[Bug 565] New: ROUTE target extension freezes machine with 2.6.20.7
https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=565 Summary: ROUTE target extension freezes machine with 2.6.20.7 Product: netfilter/iptables Version: patch-o-matic-ng Platform: x86_64 OS/Version: All Status: NEW Severity: normal Priority: P2 Component: ip_tables (kernel) AssignedTo: laforge@netfilter.org ReportedBy: guebby@gmail.com I'm using a patched kernel 2.6.20.7 with IMQ (http://www.linuximq.net) and netfilter/ROUTE-target. The machine freezes when the system has to deliver a packet that matches a ROUTE-target rule, none problem before. The rule was this: iptables -t mangle -A POSTROUTING -p tcp -d 192.168.0.1 --sport 21 -j ROUTE --oif eth1 The system hangs just when I try opening an ftp connection to it, all other conections (ssh) stop working and keyboard doesn't respond. Anyway, when I plug it, a "AT input keyboard ..." message is showed. There is no kernel panic message. My system is a AMD Athlon 64 X2 3600+, but I don't think it were an architecture problem, because I've found a guy with the same problem and has a Xeon processor (and of course different motherboard, chipsets...): http://lists.netfilter.org/pipermail/netfilter-devel/2006-December/026971.html I've also tried to disable "Dual core" support in BIOS, and when the kernel was using only one processor (checked in boot-logs) the problem remained. I forgot checking for keyboard plugging message, sorry. With PREROUTING chain there was no hang, but when I used a x86 machine with kernel 2.6.12.3 this rule did nothing with this chain, the same as now.
