            Bug ID: 205165
           Summary: Multiple race conditions in the V6 list manipulation
           Product: Base System
           Version: 10.2-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: j@nitrology.com

Creating this ticket to track conversation that has gone on in the mailing list
related to race conditions in the v6 stack.  Notably for us when processing
concurrent router advertisement packets and modifying the route lists.

https://lists.freebsd.org/pipermail/freebsd-net/2015-December/044024.html

It appears these issues have been known about for a few years, and some work
has been done on them.  We are testing these 2 and are seeing good initial
results.
