-From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

-Subject: x86/fpu: Don't cache access to fpu_fpregs_owner_ctx
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The state/owner of the FPU is saved to fpu_fpregs_owner_ctx by pointing
-to the context that is currently loaded. It never changed during the
-lifetime of a task - it remained stable/constant.
-
-After deferred FPU registers loading until return to userland was
-implemented, the content of fpu_fpregs_owner_ctx may change during
-preemption and must not be cached.
-
-This went unnoticed for some time and was now noticed, in particular
-since gcc 9 is caching that load in copy_fpstate_to_sigframe() and
-reusing it in the retry loop:
-
-  copy_fpstate_to_sigframe()
-    load fpu_fpregs_owner_ctx and save on stack
-    fpregs_lock()
-    copy_fpregs_to_sigframe() /* failed */
-    fpregs_unlock()
-         *** PREEMPTION, another uses FPU, changes fpu_fpregs_owner_ctx ***
-
-    fault_in_pages_writeable() /* succeed, retry */
-
-    fpregs_lock()
-	__fpregs_load_activate()
-	  fpregs_state_valid() /* uses fpu_fpregs_owner_ctx from stack */
-    copy_fpregs_to_sigframe() /* succeeds, random FPU content */
-
-This is a comparison of the assembly produced by gcc 9, without vs with this
-patch:

-
-Use this_cpu_read() instead this_cpu_read_stable() to avoid caching of
-fpu_fpregs_owner_ctx during preemption points.
-
-The Fixes: tag points to the commit where deferred FPU loading was
-added. Since this commit, the compiler is no longer allowed to move the
-load of fpu_fpregs_owner_ctx somewhere else / outside of the locked
-section. A task preemption will change its value and stale content will
-be observed.
