      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      Mikulas Patocka 提交于
      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 提交于
      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 提交于
      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.

          Vincenzo Maffione.
      
       9) After refactoring, some tunnel drivers allow a tunnel to be
          configured on top itself.  Fix from Nicolas Dichtel.

      tunnels: don't allow to add the same tunnel twice
      
      This series fixes the check of an existing tunnel with the same
      parameters when a new tunnel is added.  I've checked all users of
      ip_tunnel_newlink(): gre, gretap, ipip and vti. The bug exists only
      for gre and vti.

      vti: don't allow to add the same tunnel twice · 8d89dcdf
      Nicolas Dichtel 提交于
      Before the patch, it was possible to add two times the same tunnel:
      ip l a vti1 type vti remote 10.16.0.121 local 10.16.0.249 key 41
      ip l a vti2 type vti remote 10.16.0.121 local 10.16.0.249 key 41
      
      It was possible, because ip_tunnel_newlink() calls ip_tunnel_find() with the
      argument dev->type, which was set only later (when calling ndo_init handler
      in register_netdevice()). Let's set this type in the setup handler, which is
      called before newlink handler.
      
      Introduced by commit b9959fd3 ("vti: switch to new ip tunnel code").

      drivers: net: xen-netfront: fix array initialization bug · 810d8ced
      Vincenzo Maffione 提交于
      This patch fixes the initialization of an array used in the TX
      datapath that was mistakenly initialized together with the
      RX datapath arrays. An out of range array access could happen
      when RX and TX rings had different sizes.

      ====================
      Intel Wired LAN Driver Updates
      
      This series contains updates to e1000, e1000e, igb, igbvf, ixgb, ixgbe,
      ixgbevf and i40evf.
      
      Mark fixes an issue with ixgbe and ixgbevf by adding a bit to indicate
      when workqueues have been initialized.  This permits the register read
      error handling from attempting to use them prior to that, which also
      generates warnings.  Checking for a detected removal after initializing
      the work queues allows the probe function to return an error without
      getting the workqueue involved.  Further, if the error_detected
      callback is entered before the workqueues are initialized, exit without
      recovery since the device initialization was so truncated.
      
      Francois Romieu provides several patches to all the drivers to remove
      the open coded skb_cow_head.
      
      Jakub Kicinski provides a fix for igb where last_rx_timestamp should be
      updated only when Rx time stamp is read.
      
      Mitch provides a fix for i40evf where a recent change broke the RSS LUT
      programming causing it to be programmed with all 0's.

      Merge tag 'trace-3.15-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace · 0a7418f5
      Linus Torvalds 提交于
      Pull more tracing updates from Steven Rostedt:
       "This includes the final patch to clean up and fix the issue with the
        design of tracepoints and how a user could register a tracepoint and
        have that tracepoint not be activated but no error was shown.
      
        The design was for an out of tree module but broke in tree users.  The
        clean up was to remove the saving of the hash table of tracepoint
        names such that they can be enabled before they exist (enabling a
        module tracepoint before that module is loaded).  This added more
        complexity than needed.  The clean up was to remove that code and just
        enable tracepoints that exist or fail if they do not.
      
        This removed a lot of code as well as the complexity that it brought.
        As a side effect, instead of registering a tracepoint by its name, the
        tracepoint needs to be registered with the tracepoint descriptor.
        This removes having to duplicate the tracepoint names that are
        enabled.
      
        The second patch was added that simplified the way modules were
        searched for.
      
        This cleanup required changes that were in the 3.15 queue as well as
        some changes that were added late in the 3.14-rc cycle.  This final
        change waited till the two were merged in upstream and then the change
        was added and full tests were run.  Unfortunately, the test found some
        errors, but after it was already submitted to the for-next branch and
        not to be rebased.  Sparse errors were detected by Fengguang Wu's bot
        tests, and my internal tests discovered that the anonymous union
        initialization triggered a bug in older gcc compilers.  Luckily, there
        was a bugzilla for the gcc bug which gave a work around to the
        problem.  The third and fourth patch handled the sparse error and the
        gcc bug respectively.
      
        A final patch was tagged along to fix a missing documentation for the
        README file"
