Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> rtmutex: Drop rt_mutex::wait_lock before scheduling<br /> <br /> rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the<br /> good case it returns with the lock held and in the deadlock case it emits a<br /> warning and goes into an endless scheduling loop with the lock held, which<br /> triggers the &amp;#39;scheduling in atomic&amp;#39; warning.<br /> <br /> Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning<br /> and dropping into the schedule for ever loop.<br /> <br /> [ tglx: Moved unlock before the WARN(), removed the pointless comment,<br /> massaged changelog, added Fixes tag ]
