(svn 184414) X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 23 Jan 2009 08:05:06 -0000 in your logmessage for the q_time change in dummynet http://svn.freebsd.org/viewvc/base?view=revision&revision=184414 mentions an ABI change that would prevent backporting. However, as far as I can tell, the kernel side of the change is fully self-contained in the ip_dummynet module, and the only side effect on an out-of-sync userland (/sbin/ipfw) is that you would not be able to run "ipfw pipe show" -- but you can still configure ipfw rules and pipes and tables without problems. It seems to me that the change is sufficiently useful to deserve a MFC, and the side effects are negligible and do not prevent an upgrade with the usual sequence (installkernel-reboot-installworld) Any objection to an MFC ? cheers luigi
