The other day I experienced a kernel panic = when an ifaddr race condition caused a use-after-free error. It looks = like SVN commits 194760, 194813, 194819, etc. address this issue. The = original commit message for 194760 says "MFC after: 6 weeks (portions)", = but I don't see anything to indicate that the fixes were ever merged = back. Is anyone planning / willing to merge this back into the 7.X branches? = We would very much appreciate it. It looks like there are about two = dozen related commits and the diffs don't apply cleanly for me. If it = has diverged too much we'll just have to wait until we sync up with 8.0 = later this year. Thanks, Andrew -------------------------------------------------- Andrew Boyer aboyer@averesystems.com
