Hi,
Here is a series of fixes for ipv4 and ipv6 which ensure the route lookup is performed on the right routing table in VRF configurations when sending TTL expired icmp errors (useful for traceroute).
It includes tests for both ipv4 and ipv6.
These fixes address specifically address the code paths involved in sending TTL expired icmp errors. As detailed in the individual commit messages, those fixes do not address similar icmp errors related to network namespaces and unreachable / fragmentation needed messages, which appear to use different code paths.
Thanks,
Mathieu
