Subject: [RFC,net-next, 0/4] seg6: add support for SRv6 End.DT4 behavior
Date: Wed, 21 Oct 2020 20:41:12 +0200
Message-ID: <20201021184116.2722-1-andrea.mayer@uniroma2.it> (raw)

This patchset adds support for the SRv6 End.DT4 behavior.

The SRv6 End.DT4 is used to implement multi-tenant IPv4 L3VPN. It decapsulates
the received packets and performs IPv4 routing lookup in the routing table of
the tenant. The SRv6 End.DT4 Linux implementation leverages a VRF device. SRv6
End.DT4 is defined in the SRv6 Network Programming [1].

- Patch 1/4 is needed to solve a pre-existing issue with tunneled packets
  when a sniffer is attached;

- Patch 2/4 introduces two callbacks used for customizing the
  creation/destruction of a SRv6 behavior;

- Patch 3/4 is the core patch that adds support for the SRv6 End.DT4 behavior;

- Patch 4/4 adds the selftest for SRv6 End.DT4.

I would like to thank David Ahern for his support during the development of
this patch set.

Comments, suggestions and improvements are very welcome!

Thanks,
Andrea Mayer
