      Make wait_for_device_probe() also do scsi_complete_async_scans() · eea03c20
      Linus Torvalds 提交于
      Commit a7a20d10 ("sd: limit the scope of the async probe domain")
      make the SCSI device probing run device discovery in it's own async
      domain.
      
      However, as a result, the partition detection was no longer synchronized
      by async_synchronize_full() (which, despite the name, only synchronizes
      the global async space, not all of them).  Which in turn meant that
      "wait_for_device_probe()" would not wait for the SCSI partitions to be
      parsed.
      
      And "wait_for_device_probe()" was what the boot time init code relied on
      for mounting the root filesystem.
      
      Now, most people never noticed this, because not only is it
      timing-dependent, but modern distributions all use initrd.  So the root
      filesystem isn't actually on a disk at all.  And then before they
      actually mount the final disk filesystem, they will have loaded the
      scsi-wait-scan module, which not only does the expected
      wait_for_device_probe(), but also does scsi_complete_async_scans().
      
      [ Side note: scsi_complete_async_scans() had also been partially broken,
        but that was fixed in commit 43a8d39d ("fix async probe
        regression"), so that same commit a7a20d10 had actually broken
        setups even if you used scsi-wait-scan explicitly ]
      
      Solve this problem by just moving the scsi_complete_async_scans() call
      into wait_for_device_probe().  Everybody who wants to wait for device
      probing to finish really wants the SCSI probing to complete, so there's
      no reason not to do this.
      
      So now "wait_for_device_probe()" really does what the name implies, and
      properly waits for device probing to finish.  This also removes the now
      unnecessary extra calls to scsi_complete_async_scans().

      v4l2-dev: forgot to add VIDIOC_DV_TIMINGS_CAP. · c1e32096
      Hans Verkuil 提交于
      The VIDIOC_DV_TIMINGS_CAP ioctl check wasn't added to determine_valid_ioctls().
      This caused this ioctl to always return -ENOTTY.
      
      The cause for this was that for 3.5 two patch series were merged, one
      changing V4L2 core ioctl handling and one adding new functionality, and
      some of the new functionality wasn't handled by the new V4L2 core code.

         b) 3.4 commit can cause ip_vs_control_cleanup to be invoked after

          association still on a list (Neil HOrman)
      
       7) __netdev_alloc_skb() regresses on GFP_DMA using drivers because that

      11) vlan_info objects leak for the implicit vlan with ID 0 (Amir
          Hanania)
      
      12) A fix for TX time stamp handling in gianfar does not transfer socket
          ownership from one packet to another correctly, resulting in a
          socket write space imbalance (Eric Dumazet)
      
      13) Julia Lawall found several cases where we do a list iteration, and
          then at the loop termination unconditionally assume we ended up with
          real list object, rather than the list head itself (CNIC, RXRPC,
          mISDN).
      
      14) The bonding driver handles procfs moving incorrectly when a device
          it manages is moved from one namespace to another (Eric Biederman)

          dgram_sendmsg().  Dave Jones and others have hit and reported this
          bug (Sasha Levin)
      
      18) Some drivers (b44 and b43legacy) on 64-bit machines stopped working
          because of how netdev_alloc_skb() was adjusted.  Such drivers should
          now use alloc_skb() for obtaining bounce buffers.  (Eric Dumazet)
      
      19) atl1c mis-managed it's link state in that it stops the queue by hand
          on link down.  The generic networking takes care of that and this
          double stop locks the queue down.  So simply removing the driver's
          queue stop call fixes the problem (Cloud Ren)
      
      20) Fix out-of-memory due to mis-accounting in net_em packet scheduler
          (Eric Dumazet)
      
      21) If DCB and SR-IOV are configured at the same time in IXGBE the chip
          will hang because this is not supported (Alexander Duyck)
      
      22) A commit to stop drivers using netdev->base_addr broke the CNIC
          driver (Michael Chan)
      
      23) Timeout regression in ipset caused by an attempt to fix an overflow
          bug (Jozsef Kadlecsik).

      25) llcp_sock_getname() needs to check for a NULL device otherwise we
          OOPS (Sasha Levin)
      
      26) mwifiex leaks memory (Bing Zhao)

      When rpmsg drivers are built into the kernel, they must not initialize
      before the rpmsg bus does, otherwise they'd trigger a BUG() in

      To fix that, and to stop depending on arbitrary linkage ordering of

      The steps to reproduce as follow,
      
      1. On Host1, setup brige br0(192.168.1.106)
      2. Boot a kvm guest(192.168.1.105) on Host1 and start httpd
      3. Start IPVS service on Host1
         ipvsadm -A -t 192.168.1.106:80 -s rr
         ipvsadm -a -t 192.168.1.106:80 -r 192.168.1.105:80 -m
      4. Run apache benchmark on Host2(192.168.1.101)
         ab -n 1000 http://192.168.1.106/
      
      ip_vs_reply4
        ip_vs_out
          handle_response
            ip_vs_notrack
              nf_reset()
              {
                skb->nf_bridge = NULL;
              }
      
      Actually, IPVS wants in this case just to replace nfct
      with untracked version. So replace the nf_reset(skb) call
      in ip_vs_notrack() with a nf_conntrack_put(skb->nfct) call.

      ixgbevf: Fix panic when loading driver · 10cc1bdd
      Alexander Duyck 提交于
      This patch addresses a kernel panic seen when setting up the interface.
      Specifically we see a NULL pointer dereference on the Tx descriptor cleanup
      path when enabling interrupts.  This change corrects that so it cannot
      occur.

      MAINTAINERS: reflect actual changes in IEEE 802.15.4 maintainership · 68653359
      Dmitry Eremin-Solenikov 提交于
      As the life flows, developers priorities shifts a bit. Reflect actual
      changes in the maintainership of IEEE 802.15.4 code: Sergey mostly
      stopped cared about this piece of code. Most of the work recently was
      done by Alexander, so put him to the MAINTAINERS file to reflect his
      status and to ease the life of respective patches.
      
      Also add new net/mac802154/ directory to the list of maintained files.
