      ALSA: hda - Fix lost sound due to stream_pm ops cleanup · b47eee2e
      Takashi Iwai authored
      The commit [49fb1897: ALSA: hda - Set stream_pm ops automatically
      by generic parser] resulted in regressions on some Realtek and VIA
      codecs because these drivers set patch_ops after calling the generic
      parser, thus stream_pm got cleared to NULL again.  I haven't noticed
      since I tested with IDT codec.
      
      Restore (partial revert) the stream_pm ops for them to fix the
      regression.

      ALSA: hda - Disable power_save_node for IDT92HD71bxx · c545f799
      Takashi Iwai authored
      We've got a regression report that 4.1-rc causes noises on a Dell
      laptop.  Similar like Realtek codec, this seems also triggered by the
      recent power_save_node feature.  As this kind of issue is quite hard
      to debug without actual hardware, disable the power_save_node flag for
      this codec as a workaround.

      sctp: Fix mangled IPv4 addresses on a IPv6 listening socket · 9302d7bb
      Jason Gunthorpe authored
      sctp_v4_map_v6 was subtly writing and reading from members
      of a union in a way the clobbered data it needed to read before
      it read it.
      
      Zeroing the v6 flowinfo overwrites the v4 sin_addr with 0, meaning
      that every place that calls sctp_v4_map_v6 gets ::ffff:0.0.0.0 as the
      result.
      
      Reorder things to guarantee correct behaviour no matter what the
      union layout is.
      
      This impacts user space clients that open an IPv6 SCTP socket and
      receive IPv4 connections. Prior to 299ee user space would see a
      sockaddr with AF_INET and a correct address, after 299ee the sockaddr
      is AF_INET6, but the address is wrong.

      net_sched: invoke ->attach() after setting dev->qdisc · 86e363dc
      WANG Cong authored
      For mq qdisc, we add per tx queue qdisc to root qdisc
      for display purpose, however, that happens too early,
      before the new dev->qdisc is finally set, this causes
      q->list points to an old root qdisc which is going to be
      freed right before assigning with a new one.
      
      Fix this by moving ->attach() after setting dev->qdisc.
      
      For the record, this fixes the following crash:

      xen-netfront: properly destroy queues when removing device · ad068118
      David Vrabel authored
      xennet_remove() freed the queues before freeing the netdevice which
      results in a use-after-free when free_netdev() tries to delete the
      napi instances that have already been freed.
      
      Fix this by fully destroy the queues (which includes deleting the napi
      instances) before freeing the netdevice.

      mlx4_core: Fix fallback from MSI-X to INTx · f4ecf29f
      Benjamin Poirier authored
      The test in mlx4_load_one() to remove MLX4_FLAG_MSI_X expects mlx4_NOP() to
      fail with -EBUSY. It is also necessary to avoid the reset since the device
      is not fully reinitialized before calling mlx4_start_hca() a second time.
      
      Note that this will also affect mlx4_test_interrupts(), the only other user
      of MLX4_CMD_NOP.

      lguest: fix out-by-one error in address checking. · 83a35114
      Rusty Russell authored
      This bug has been there since day 1; addresses in the top guest physical
      page weren't considered valid.  You could map that page (the check in
      check_gpte() is correct), but if a guest tried to put a pagetable there
      we'd check that address manually when walking it, and kill the guest.

      xen/netback: Properly initialize credit_bytes · ce0e5c52
      Ross Lagerwall authored
      Commit e9ce7cb6 ("xen-netback: Factor queue-specific data into queue
      struct") introduced a regression when moving queue-specific data into
      the queue struct by failing to set the credit_bytes field. This
      prevented bandwidth limiting from working. Initialize the field as it
      was done before multiqueue support was added.
