Brian Behlendorf ceb49b0acd Add object type checking to zap_lockdir() ... If a non-ZAP object is passed to zap_lockdir() it will be treated as a valid ZAP object. This can result in zap_lockdir() attempting to read what it believes are leaf blocks from invalid disk locations. The SCSI layer will eventually generate errors for these bogus IOs but the caller will hang in zap_get_leaf_byblk(). The good news is that is a situation which can not occur unless the pool has been damaged. The bad news is that there are reports from both FreeBSD and Solaris of damaged pools. Specifically, there are normal files in the filesystem which reference another normal file as their parent. Since pools like this are known to exist the zap_lockdir() function has been updated to verify the type of the object. If a non-ZAP object has been passed it EINVAL will be returned immediately.
