Currently, there is an issue in the raw receive code where raw receives are allowed to happen on top of previously non-raw received datasets. This is a problem because the source-side dataset doesn't know about how the blocks on the destination were encrypted. As a result, any MAC in the objset's checksum-of-MACs tree that is a parent of both blocks encrypted on the source and blocks encrypted by the destination will be incorrect. This will result in authentication errors when we decrypt the dataset. This patch fixes this issue by adding a new check to the raw receive code. The code now maintains an "IVset guid", which acts as an identifier for the set of IVs used to encrypt a given snapshot. When a snapshot is raw received, the destination snapshot will take this value from the DRR_BEGIN payload. Non-raw receives and normal "zfs snap" operations will cause ZFS to generate a new IVset guid. When a raw incremental stream is received, ZFS will check that the "from" IVset guid in the stream matches that of the "from" destination snapshot. If they do not match, the code will error out the receive, preventing the problem. This patch requires an on-disk format change to add the IVset guids to snapshots and bookmarks. As a result, this patch has errata handling and a tunable to help affected users resolve the issue with as little interruption as possible.
