Subject: [net-next,v1,0/5] seg6: add support for SRv6 End.DT4 behavior
Date: Tue, 3 Nov 2020 13:52:37 +0100 [thread overview]
Message-ID: <20201103125242.11468-1-andrea.mayer@uniroma2.it> (raw)
This patchset provides support for the SRv6 End.DT4 behavior.
The SRv6 End.DT4 is used to implement multi-tenant IPv4 L3 VPN. 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. The SRv6 End.DT4 is defined in the SRv6 Network
Programming [1].
- Patch 1/5 is needed to solve a pre-existing issue with tunneled packets
when a sniffer is attached;
- Patch 2/5 improves the management of the seg6local attributes used by the
SRv6 behaviors;
- Patch 3/5 introduces two callbacks used for customizing the
creation/destruction of a SRv6 behavior;
- Patch 4/5 is the core patch that adds support for the SRv6 End.DT4 behavior;
- Patch 5/5 adds the selftest for SRv6 End.DT4 behavior.
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
