This is a note to let you know that I have just added a patch titled bonding: 802.3ad: make aggregator_identifier bond-private to the linux-3.5.y-queue branch of the 3.5.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-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From cbdc802aeab3b2e93e00bce16ab447800cbf4f47 Mon Sep 17 00:00:00 2001 From: Jiri Bohac <jiri@boha.cz> Date: Fri, 14 Feb 2014 18:13:50 +0100 Subject: bonding: 802.3ad: make aggregator_identifier bond-private commit 163c8ff30dbe473abfbb24a7eac5536c87f3baa9 upstream. aggregator_identifier is used to assign unique aggregator identifiers to aggregators of a bond during device enslaving. aggregator_identifier is currently a global variable that is zeroed in bond_3ad_initialize(). This sequence will lead to duplicate aggregator identifiers for eth1 and eth3: create bond0 change bond0 mode to 802.3ad enslave eth0 to bond0 //eth0 gets agg id 1 enslave eth1 to bond0 //eth1 gets agg id 2 create bond1 change bond1 mode to 802.3ad enslave eth2 to bond1 //aggregator_identifier is reset to 0 //eth2 gets agg id 1 enslave eth3 to bond0 //eth3 gets agg id 2 Fix this by making aggregator_identifier private to the bond.
