      [media] media/usb/gspca: Add support for Scopium astro webcam (0547:7303) · 30ece903
      Robert Butora authored
      This patch does not modify existing drivers. It adds subdriver
      to gspca for DTCS033 (Scopium) webcam for astrophotography.
      The patch adds dtcs033.c and modifies Kconfig and Makefile.

      [media] Prefer gspca_sonixb over sn9c102 for all devices · 877ed143
      Jean Delvare authored
      The sn9c102 driver is deprecated. It was moved to staging in
      anticipation of its removal in a future kernel version. However, USB
      devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
      both sn9c102 and gspca_sonixb are enabled.
      
      We must migrate all the users of these devices to the gspca_sonixb
      driver now, so that it gets sufficient testing before the sn9c102
      driver is finally phased out.

      [media] media: davinci: vpfe: make sure all the buffers unmapped and released · c1d1e40b
      Lad, Prabhakar authored
      this patch makes sure that it terminates if any IO in
      progress and also makes sure that all the buffers are unmapped.
      It was observed that with several runs of application the application
      sometimes failed to allocate memory, This patch makes sure it
      all the buffers are released.
      
      Using kmemleak it was found that buffer were not released, this patch
      fixes following issue,
      
       echo scan > /sys/kernel/debug/kmemleak
        Kernel message reads:
            memleak: 3 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
      
      Then,

      "vb2: only call start_streaming if sufficient buffers are queued"
      the vb2 framework warns on (WARN_ON()) if all the active buffers
      are not released when streaming is stopped, initially the vb2 silently
      released the buffer internally if the buffer was not released by
      the driver.
      Also this patch moves the disabling of interrupts from relase() callback
      to stop_streaming() callback as which needs to be done ideally.
      
      This patch fixes following issue:

      RTL2832 SDR extension module is currently on staging. SDR module
      headers were included from staging causing direct dependency staging

      Motivation of that change comes from Luis / driver backports project.

      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      Mikulas Patocka authored
      This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
      returns QUEUE FULL status.
      
      When the controller encounters an error (including QUEUE FULL or BUSY
      status), it aborts all not yet submitted requests in the function
      sym_dequeue_from_squeue.
      
      This function aborts them with DID_SOFT_ERROR.
      
      If the disk has full tag queue, the request that caused the overflow is
      aborted with QUEUE FULL status (and the scsi midlayer properly retries
      it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
      the following requests with DID_SOFT_ERROR --- for them, the midlayer
      does just a few retries and then signals the error up to sd.
      
      The result is that disk returning QUEUE FULL causes request failures.
      
      The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
      (rebranded ST336607LC) with command queue 48 or 64 tags.  The disk has
      64 tags, but under some access patterns it return QUEUE FULL when there
      are less than 64 pending tags.  The SCSI specification allows returning
      QUEUE FULL anytime and it is up to the host to retry.

      powerpc: Don't try to set LPCR unless we're in hypervisor mode · 18aa0da3
      Paul Mackerras authored
      Commit 8f619b54 ("powerpc/ppc64: Do not turn AIL (reloc-on
      interrupts) too early") added code to set the AIL bit in the LPCR
      without checking whether the kernel is running in hypervisor mode.  The
      result is that when the kernel is running as a guest (i.e., under
      PowerKVM or PowerVM), the processor takes a privileged instruction
      interrupt at that point, causing a panic.  The visible result is that
      the kernel hangs after printing "returning from prom_init".
      
      This fixes it by checking for hypervisor mode being available before
      setting LPCR.  If we are not in hypervisor mode, we enable relocation-on
      interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

      futex: update documentation for ordering guarantees · d7e8af1a
      Davidlohr Bueso authored
      Commits 11d4616b ("futex: revert back to the explicit waiter
      counting code") and 69cd9eba ("futex: avoid race between requeue and
      wake") changed some of the finer details of how we think about futexes.
      One was a late fix and the other a consequence of overlooking the whole
      requeuing logic.
      
      The first change caused our documentation to be incorrect, and the
      second made us aware that we need to explicitly add more details to it.

      Pull yet more networking updates from David Miller:
      
       1) Various fixes to the new Redpine Signals wireless driver, from
          Fariya Fatima.
      
       2) L2TP PPP connect code takes PMTU from the wrong socket, fix from
          Dmitry Petukhov.
      
       3) UFO and TSO packets differ in whether they include the protocol
          header in gso_size, account for that in skb_gso_transport_seglen().
         From Florian Westphal.
      
       4) If VLAN untagging fails, we double free the SKB in the bridging
          output path.  From Toshiaki Makita.
      
       5) Several call sites of sk->sk_data_ready() were referencing an SKB
          just added to the socket receive queue in order to calculate the
          second argument via skb->len.  This is dangerous because the moment
          the skb is added to the receive queue it can be consumed in another
          context and freed up.
      
          It turns out also that none of the sk->sk_data_ready()
          implementations even care about this second argument.
      
          So just kill it off and thus fix all these use-after-free bugs as a
          side effect.
      
       6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti.
      
       7) pktgen needs to do locking properly for LLTX devices, from Daniel
          Borkmann.
      
       8) xen-netfront driver initializes TX array entries in RX loop :-) From
          Vincenzo Maffione.
      
       9) After refactoring, some tunnel drivers allow a tunnel to be
          configured on top itself.  Fix from Nicolas Dichtel.
