Title:
aws: xen-netfront: prevent potential error on hibernate
Status in linux-aws package in Ubuntu:
Fix Released
Status in linux-aws source package in Focal:
Fix Released
Status in linux-aws source package in Groovy:
Fix Committed
Bug description:
[Impact]
On hibernation xen-netfront is setting the device state on the xenbus
to "Closing" and then it's waiting for the backend state to
acknowledge that state (with a timeout). However, if the device is
already in the state "Closed" this opteration will always hit the
timeout, preventing the system to hibernate correctly.
[Test case]
It is a quite rare condition that can be reproduced
hibernating/resuming a Xen instance multiple times. When the problem
happens we should in the log a Xen error message like the following:
Freezing timed out; the device may become inconsistent state
[Fix]
If the device is already in the state "Closed", simply tear it down
without notifying the Xen backend.
[Regression potential]
The fix would just prevent aborting hibernation if the netfront device
is already in a "Closed" state. The resume callback is forcing the
device into the "Initializing" state anyway, basically forcing a reset
of the device, so nothing else in the state machine can be potentially
broken.
