Hi,
We've a report of F11 qemu segfaulting when using read-only
images here:
https://bugzilla.redhat.com/497170
Looking at the current code in stable, there is clearly some
borkage:
- No error handling in bdrv_aio_rw_vector()
- No error handling in dma_bdrv_cb()/dma_bdrv_io()
- VectorTranslationState is leaked by bdrv_aio_rw_vector_cb()
- dma_aio_cancel() is cancelling the wrong aio
The rest of Avi's aio cancellation patches actually fixes all
these problems. Please apply to stable.
Cheers,
Mark.
