Hi, so with the CentOS 6.3 kernel the accept_local patch that was introduced with 2.6.33 has now become available with the main distro kernel.
Has anyone experimented with setting up a gateway system that also acts as a directly routed LVS system? Previously this wasn't possible because the returning packets were classified as martians because they had a source IP that was also configured on the local system which is considered bogus but now when you set accept_local to 1 you can tell the system to accept such packets. I tried this yesterday and while the packets get no longer dropped when doing a ping from a realserver with the VIP specified as source the moment I actually set up the balancing on the director and make a request to the VIP from a client machine the cpu usage in the gateway/director goes to 100%. AFAICT it seems LVS does seem to get into a loop when the returning packet arrives on the director. Does anyone have an idea what might be going on here and how to fix it?
