Kirk McKusick abe53f7e91 This fixes a bug in UFS2 exported NFS volumes. An NFS client can ... crash a server that has exported UFS2 by presenting a filehandle with an inode number that references an uninitialized inode in a cylinder group. The problem is that UFS2 only initializes blocks of inodes as they are first allocated and ffs_fhtovp() does not validate that the inode is in a range of inodes that have been initialized. Attempting to read an uninitialized inode gets random data from the disk. When the kernel tries to interpret it as an inode, panics often arise.
