This is a bunch of RDMA fixes, the first is a race
I spotted a while ago that you don't hit during normal
operation; the rest are to do with migration failure and
cancellation that I started looking at because of lp1545052 which
is a failure to recover on the source if the destination
fails.
I'm pretty sure there are other cases where the source
might hang waiting for a failed destination; particularly
if the destination hangs rather than fails completely;
one I know of is waiting for the event after the rdma_disconnect
but I don't have a good fix for it. Suggestions welcome.
v4
Fix more error paths in qemu_rdma_block_for_wrid - often
the 'ret' wasn't set. Fix that and also fix the case we
add to also set the ret. Spotted by Peter.
Dr. David Alan Gilbert (6):
migration/rdma: Fix race on source
migration: Close file on failed migration load
migration/rdma: fix qemu_rdma_block_for_wrid error paths
migration/rdma: Allow cancelling while waiting for wrid
migration/rdma: Safely convert control types
migration/rdma: Send error during cancelling
