conntrackd: flush operation use the child process and origin infrastructure
With this patch, the flush operation is performed by a child process. Thus, the parent process digests destroy events that ctnetlink reports back and, thanks to the origin infrastructure, we skip the messy implicit synchronization that are triggered by such events. This patch requires a Linux kernel >= 2.6.29 to benefit from this change, otherwise it has no effect. Signed-off-by: Pablo Neira Ayuso <>
