Conrad Meyer e6790841f7 UFS2: Fix DoS due to corrupted extattrfile ... Prior versions of FreeBSD (11.x) may have produced a corrupt extattr file. (Specifically, r312416 accidentally fixed this defect by removing a strcpy.) CURRENT FreeBSD supports disk images from those prior versions of FreeBSD. Validate the internal structure as soon as we read it in from disk, to prevent these extattr files from causing invariants violations and DoS. Attempting to access the extattr portion of these files results in EINTEGRITY. At this time, the only way to repair files damaged in this way is to copy the contents to another file and move it over the original.
