Sorry for top post (android)

Proposed algo:
Ofd=open(/proc,o_search)
follow link /proc/self/fd/ofd/../proc
If bug will resolve to
/proc/self/fd/proc that does not exist
If not bug suceed (because we have already opened /proc

How can you guarantee that /proc/self/fd/../proc does not exist? If fd
is /usr, then it resolves to /usr/../proc which resolves to /proc which
does exist.
