Re: /proc filesystem allows bypassing directory permissions on Linux

Hi! (no html, please).
Proc does not need to be fixed, because /proc is referring to a file inode.
Well, that does not mean /proc does not need fixing.
You are expecting transactional behavior in /proc, where /proc only registers object information.
...
And I think you would agree about your mis-interpretation earlier if not so many people had the same mis-interpretation of the virtual /proc mechanism
I think you understand the issue by now. But you think it should be documented better, not fixed. I believe that fixing it is easier and better option -- because surprises in security area are bad -- but of course, if this is documented properly, it also stops being so big problem.
