This is a note to let you know that I have just added a patch titled net: bridge: convert MLDv2 Query MRC into msecs_to_jiffies for to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.11. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 32091c463948202d655b160d59050aa25dc4f70b Mon Sep 17 00:00:00 2001 From: Daniel Borkmann <dborkman@redhat.com> Date: Thu, 29 Aug 2013 23:55:05 +0200 Subject: net: bridge: convert MLDv2 Query MRC into msecs_to_jiffies for max_delay MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 2d98c29b6fb3de44d9eaa73c09f9cf7209346383 ] While looking into MLDv1/v2 code, I noticed that bridging code does not convert it's max delay into jiffies for MLDv2 messages as we do in core IPv6' multicast code. RFC3810, 5.1.3. Maximum Response Code says: The Maximum Response Code field specifies the maximum time allowed before sending a responding Report. The actual time allowed, called the Maximum Response Delay, is represented in units of milliseconds, and is derived from the Maximum Response Code as follows: [...] As we update timers that work with jiffies, we need to convert it.
