** Changed in: linux-ec2 (Ubuntu Lucid)
Status: New => Fix Released
** Changed in: linux (Ubuntu Utopic)
Status: Confirmed => Fix Committed
** Description changed:
If uaddr == uaddr2, then we have broken the rule of only requeueing from
a non-pi futex to a pi futex with this call. If we attempt this, then
dangling pointers may be left for rt_waiter resulting in an exploitable
condition.
