Kernel compiled with gcc 4.0
I'm would reassign this to DaveM, if he had a bugzilla account. rp_filter is a feature of the routing code, and not related to netfilter/iptables. Your kernel is compiled with gcc 4.0.0 This gcc version had at least one serious bug resulting in known kernel miscompilations. Does the problem still occur when using gcc 4.0.1? OK with gcc 4.0.2 the problen has solved Please close the bug. |
Most recent kernel where this bug did not occur: Distribution: Debian unstabble Hardware Environment: compaq nx7010 Software Environment: Debian networking startup script Problem Description: each one
