What do:
ls -ld /proc/1707
ls -la /proc/1707
show? Adjust for your running system, of course.
Maybe /proc itself has exciting new permissions.
Maybe lsof has exciting new setgidness or something.
Or SELinux hates you.
BTW, _does_ this work as root? Just for info.
Cheers,
Yes it does work for root.
So, my question still remains that a process
that opens files/devices/dirs....etc,
having user X's uid/gid for credentials, can open these
resources, yet lsof, invoked by same user X, belches out
Permission denied.
How were such resources opened using X's credentials
in the first place, if user X has no permission to read the link?
