Date: Mon, 3 Dec 2012 10:57:13 +0100 (CET) Message-ID: <Pine.LNX.4.64.1212031042330.4310@cube> Hello. Here comes the patch thats makes possible to use ipset directly in ip rule (policy routing). This makes such configuration easier, because there is no need to have: iptables -t mangle -A OUTPUT -m set --set ... -j MARK --set-mark 1 ip rule add fwmark 1 lookup 1 Additionaly, it fixes issue with wrong src addr for unconnected protocols such as UDP, ICMP... https://bugzilla.kernel.org/show_bug.cgi?id=16216 Brief question to google confirms that few people might have interest in this patch. ftp://borg.uu3.net/home/borg/patch/linux-2.6.27.62+ipset_routing.patch ftp://borg.uu3.net/home/borg/patch/iproute2+ipset.patch To install the patch, first you need to patch kernel using ipset (4.5 preffered). Then, you apply this patch. Additionaly, you need to patch iproute2 to use new match: ip route add ipset <name> src|dst lookup <n> The place for this is IPSET webpage I belive, but I mailing it here because I have few concerns: - Now this patch needs IPSET to be compiled into kernel (no modules) I would like to fix it - I had to add 2 new function to API of IPSET, and so I probably doing something wrong. - Patch is conditional: CONFIG_IP_NF_SET except in 2 places: size_t payload = NLMSG_ALIGN(sizeof(struct fib_rule_hdr)) enum { ... } // FRA_* defs Not sure if this is correct way. Sorry that patch is agaist old kernel. I just needed it fast for monday and this one is run on 2 production boxes I need this feature. One box is already patched and is running fine (non SMP host). No issues so far. I will compare CPU usage after roughty 24 hrs. Second box is SMP and I will try to patch it ASAP.
