IPV6 fragmentation and mtu issue
Status in neutron:
Confirmed
Status in OpenStack Compute (nova):
Confirmed
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Trusty:
Fix Released
Status in linux source package in Vivid:
Fix Released
Bug description:
Fragmented IPv6 packets are REJECTED by ip6tables on compute nodes.
The traffic is goign through an intra-VM network and the packet loss
is hurting the system.
There is a patch for this issue:
http://patchwork.ozlabs.org/patch/434957/
I would like to know is there any bug report or official release date
for this issue ?
This is pretty critical for my deployment.
Thanks in advance,
BR,
Gyula
