Subject: [RFC PATCH v2 0/3] l3mdev icmp error route lookup fixes
Date: Fri, 18 Sep 2020 14:17:58 -0400 [thread overview]
Message-ID: <20200918181801.2571-1-mathieu.desnoyers@efficios.com> (raw)
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 issues related to network
namespaces and unreachable / fragmentation needed messages, which appear
to use different code paths.
Thanks,
Mathieu
