      block: don't use un-ordered __set_current_state(TASK_UNINTERRUPTIBLE) · 1ac5cd49
      Linus Torvalds authored
      This mostly reverts commit 849a3700 ("block: avoid ordered task
      state change for polled IO").  It was wrongly claiming that the ordering
      wasn't necessary.  The memory barrier _is_ necessary.
      
      If something is truly polling and not going to sleep, it's the whole
      state setting that is unnecessary, not the memory barrier.  Whenever you
      set your state to a sleeping state, you absolutely need the memory
      barrier.
      
      Note that sometimes the memory barrier can be elsewhere.  For example,
      the ordering might be provided by an external lock, or by setting the
      process state to sleeping before adding yourself to the wait queue list
      that is used for waking up (where the wait queue lock itself will
      guarantee that any wakeup will correctly see the sleeping state).
      
      But none of those cases were true here.
      
      NOTE! Some of the polling paths may indeed be able to drop the state
      setting entirely, at which point the memory barrier also goes away.
      
      (Also note that this doesn't revert the TASK_RUNNING cases: there is no
      race between a wakeup and setting the process state to TASK_RUNNING,
      since the end result doesn't depend on ordering).

      Pull integrity updates from James Morris:
       "In Linux 4.19, a new LSM hook named security_kernel_load_data was
        upstreamed, allowing LSMs and IMA to prevent the kexec_load syscall.
        Different signature verification methods exist for verifying the
        kexec'ed kernel image. This adds additional support in IMA to prevent
        loading unsigned kernel images via the kexec_load syscall,
        independently of the IMA policy rules, based on the runtime "secure
        boot" flag. An initial IMA kselftest is included.
      
        In addition, this pull request defines a new, separate keyring named
        ".platform" for storing the preboot/firmware keys needed for verifying
        the kexec'ed kernel image's signature and includes the associated IMA
        kexec usage of the ".platform" keyring.
      
        (David Howell's and Josh Boyer's patches for reading the
        preboot/firmware keys, which were previously posted for a different
        use case scenario, are included here)"
