Make qemu_peek_buffer repeatedly call fill_buffer until it gets all the data it requires, or until there is an error. At the moment, qemu_peek_buffer will try one qemu_fill_buffer if there isn't enough data waiting, however the kernel is entitled to return just a few bytes, and still leave qemu_peek_buffer with less bytes than it needed. I've seen this fail in a dev world, and I think it could theoretically fail in the peeking of the subsection headers in the current world. Comment qemu_peek_byte to point out it's not guaranteed to work for non-continuous peeks Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: ChenLiang <chenliang0016@icloud.com> Signed-off-by: Juan Quintela <quintela@redhat.com> |
