Hi,
Here is an updated series of fixes for ipv4 and ipv6 which 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.
The main changes since the last round are updates to the selftests.
Thanks,
Mathieu
