Subject: ls prints garbage when listing contents of a directory without exec
 permissions
Date: Wed, 11 Nov 2020 18:24:17 -0500

When running 'ls -l' on a directory that the user does
not have execute permissions on, ls(1) still attempts
to generate the long listing and prints the various
fields with garbage:

$ mkdir dir
$ touch dir/file
$ chmod a-x dir
$ ls -ld dir
drw-r--r-- 2 jschauma users 28 Nov 11 23:15 dir
$ ls -la dir
ls: cannot access dir/.: Permission denied
ls: cannot access dir/..: Permission denied
ls: cannot access dir/file: Permission denied
total 0
d????????? ? ? ? ?            ? .
d????????? ? ? ? ?            ? ..
-????????? ? ? ? ?            ? file
$ 


Expected output:

$ ls -la dir
ls: cannot access dir/.: Permission denied
ls: cannot access dir/..: Permission denied
ls: cannot access dir/file: Permission denied
$ 

This is coreutils-8.32.
