      tun: fix LSM/SELinux labeling of tun/tap devices · 5dbbaf2d
      Paul Moore authored
      
      
      This patch corrects some problems with LSM/SELinux that were introduced
      with the multiqueue patchset.  The problem stems from the fact that the
      multiqueue work changed the relationship between the tun device and its
      associated socket; before the socket persisted for the life of the
      device, however after the multiqueue changes the socket only persisted
      for the life of the userspace connection (fd open).  For non-persistent
      devices this is not an issue, but for persistent devices this can cause
      the tun device to lose its SELinux label.
      
      We correct this problem by adding an opaque LSM security blob to the
      tun device struct which allows us to have the LSM security state, e.g.
      SELinux labeling information, persist for the lifetime of the tun
      device.  In the process we tweak the LSM hooks to work with this new
      approach to TUN device/socket labeling and introduce a new LSM hook,
      security_tun_dev_attach_queue(), to approve requests to attach to a
      TUN queue via TUNSETQUEUE.
      
      The SELinux code has been adjusted to match the new LSM hooks, the
      other LSMs do not make use of the LSM TUN controls.  This patch makes
      use of the recently added "tun_socket:attach_queue" permission to
      restrict access to the TUNSETQUEUE operation.  On older SELinux
      policies which do not define the "tun_socket:attach_queue" permission
      the access control decision for TUNSETQUEUE will be handled according
      to the SELinux policy's unknown permission setting.

      spin_is_locked() on a non !SMP build is kind of useless.
      
      BUG_ON(!spin_is_locked(xx)) is guaranteed to crash.
      
      Just remove this check in reqsk_fastopen_remove() as
      the callers do hold the socket lock.

      vfs: add missing virtual cache flush after editing partial pages · 6d283dba
      Linus Torvalds authored
      
      
      Andrew Morton pointed this out a month ago, and then I completely forgot
      about it.
      
      If we read a partial last page of a block device, we will zero out the
      end of the page, but since that page can then be mapped into user space,
      we should also make sure to flush the cache on architectures that have
      virtual caches.  We have the flush_dcache_page() function for this, so
      use it.
      
      Now, in practice this really never matters, because nobody sane uses
      virtual caches to begin with, and they largely exist on old broken RISC
      arhitectures.
      
      And even if you did run on one of those obsolete CPU's, the whole "mmap
      and access the last partial page of a block device" behavior probably
      doesn't actually exist.  The normal IO functions (read/write) will never
      see the zeroed-out part of the page that migth not be coherent in the
      cache, because they honor the size of the device.
      
      So I'm marking this for stable (3.7 only), but I'm not sure anybody will
      ever care.

      be2net: fix unconditionally returning IRQ_HANDLED in INTx · d0b9cec3
      Sathya Perla authored
      commit e49cc34f
      
       introduced an unconditional IRQ_HANDLED return in be_intx()
      to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel
      from detecting interrupt storms due to broken HW.
      
      The BE2/Lancer HW issues are:
      1) In Lancer, there is no means for the driver to detect if the interrupt
      belonged to device, other than counting and notifying events.
      2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler
      to be called multiple times till the de-assert happens.
      3) In BE2, we see an occasional interrupt even when EQs are unarmed.
      
      Issue (1) can cause the notified events to be orphaned, if NAPI was already
      running.
      This patch fixes this issue by scheduling NAPI only if it is not scheduled
      already. Doing this also takes care of possible events_get() race that may be
      caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first
      time zero events are detected.
      (Thanks Ben H. for the feedback and suggestions.)

      sparc: remove __devinit, __devexit annotations · b7c13f76

      __devinit, __devexit annotations are nops - so drop them.
      Likewise for __devexit_p.
      
      Adjusted alignment of arguments when needed.
