In zfs_acl_chown_setattr(), the zfs_mode_comput() function is used to create a traditional mode value based on an ACL. If no ACL exists, this processing shouldn't be done. Problems caused by this were most evident on version 4 filesystems which not only don't have system attributes, and also frequently have empty ACLs. On such filesystems, performing a chown() operation could have the effect of dirtying the mode bits in memory but not on the file system as follows: # create a file with typical mode of 664 echo test > test chown anyuser test ls -l test and the mode will show up as all zeroes. Unmounting/mounting and/or exporting/importing the filesystem will reveal the proper mode again.
