    sys/netinet6         nd6.c 
  Log:
  - In nd6_rtrequest(), when caching an rtentry, don't forget
    to add a reference to it; otherwise, we could later access
    a freed memory.  This is believed to fix panics some users
    were observing when running route6d(8), and is similar to
    the fix in sys/netinet/if_ether.c,v 1.139 by glebius at .
  
  PR:             kern/93910, kern/105437
  Testing by:     Wojciech Puchar (still ongoing)
  
  - Add rtentry locking to nd6_output() similar to rt_check().
