X-Git-Tag: v4.13~29341^2~8 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=69cdf8f92a8dd191eee0e834c631d84a140b1121;p=mirror_ubuntu-bionic-kernel.git ipv6 route: Fix lifetime in netlink. We could not see appropriate lifetime if the route had been scheduled to expired at 0 (in jiffies). We should check rt6i_flags instead of rt6i_expires to determine whether lifetime is valid or not.
