Mounting on a directory with permissions 0700 leads to the links . and .. in the mounted filesystem to be inaccessible to non- owners. This is confusing and should have been documented in the mount man pages. Fix: Here are patches for mount(2) and mount(8) which add some explanation under BUGS. I think that's the appropriate place as it can't be the intended one. How-To-Repeat: Try such a mount and then as a mere user try accessing .. in the newly mounted filesystem. Have fun.
State Changed From-To: open->suspended awaiting committer
State Changed From-To: suspended->closed Fixed in rev 1.23 of "mount.8", thanks! I felt mount(8) was a more appropriate place for this doc path than mount(2).
