Train Series Release Notes¶
1.17.0¶
Bug Fixes¶
As part of a bug #1715317, MAC ageing was disabled for the intermediate bridge created as part of the hybrid plug mechanism. During the removal of
brctl
, this behavior was inadvertently applied to all linux bridges created by os-vif including those used in the linuxbridge driver. As a result this can lead to packet flooding (see bug #1837252) when instances are migrated. This behavior has been reverted so that the default mac ageing is determined by the kernel and is not set when using the os-vif linux bridge plugin.
1.16.0¶
Security Issues¶
Prevent Linux Bridge from replying to ARP messages. It should reply only if the target IP address is a local address configured on the incoming interface and it should always use the best local address. See The ARP flux problem for more information.
