Status: Precise Development Kernel

We rebased to v3.2.1 and uploaded linux-3.2.0-9.16 last friday. I’ve
also started prepping Precise LBM and plan to also open the Q git repo.
Please keep in mind that Alpha 2 is nearing (Thurs Feb 2). I plan on
uploading our final Alpha2 kernel on either the Friday or Monday prior
to the milestone. For any patches needing to land in Alpha2, they need
to be sent and applied before next Friday, Jan 27.


Status: CVE’s

=== CVE Metrics ===

Currently open CVEs for each supported branch:

In the last two weeks there have been 19 CVE added. Many of these were
older CVEs where fixes have already hit our trees so the fallout is
somewhat mitigated.
