Clearview Updates

Clearview Updates

Clearview development has been proceeding at a rapid pace -- here's a quick update on the milestones reached over the past month:

  • Thanks especially to Sebastien's hard work, the Nemo Binary Compatibility and Nemo Generalization components have been reviewed by the OpenSolaris community, approved by our internal architectural review board, and are nearing integration into OpenSolaris. With these, non-Ethernet Nemo drivers (such as the Clearview IP Tunneling driver) will be able to be written -- not to mention Nemo WiFi drivers (which are almost ready for intergation into OpenSolaris as well). This work also brings us a step closer to making the Nemo interfaces available for third-party use, and paves the way for TCP LSO support.
  • Cathy and Dan Groves have published a proposal for improving the observability of VLAN's, which will be submitted to the our architecture review board shortly. These changes are necessary for Clearview's Nemo Unification component, but are also quite useful in their own regard since they make it significantly easier to track down networking problems that occur on VLANs. Code that implements the proposal is already running internally, and is also destined for a nearby build of OpenSolaris.
  • Phil Kirk has published our proposed architecture for IP Observability. With this work comes the vital ability to debug intra-zone and inter-zone networking problems using traditional utilities such as ethereal and snoop -- along with opening the door for interesting possibilities such as inter-zone IDS's. Again, the code that implements this proposal is already running internally.
  • Sagun Shakya has published our proposal for a public library that can be used to communicate with link-layer devices via DLPI. This work is necessary for [Vanity Naming], but also allows us to centralize all application-level DLPI handling -- and to torch thousands of lines of tedious and obscure code. Expect a revised proposal -- based on our experiences of porting the Solaris DHCP client to use it -- to be posted to OpenSolaris shortly.
I'm also happy to report that we will shortly be making builds of the Clearview gate available to the OpenSolaris community. These early-access bits will include everything mentioned above.

And finally, as promised, here are my photos from Sichuan. Thanks again to Cathy Zhou and her family for taking me on this amazing trip.
