If a topology event subscription fails for any reason, such as out
of memory, max number reached or because we received an invalid
request the correct behavior is to terminate the subscribers
connection to the topology server. This is currently broken and

The recursion occurs when subscr_terminate tries to grab the

We fix this by checking if the request to establish a new

the subscriber after we have released the subscriber lock.

The VXLAN neigh_reduce() code is completely non-functional since
check-in. Specific errors:

1) The original code drops all packets with a multicast destination address,
	even though neighbor solicitations are sent to the solicited-node
	address, a multicast address. The code after this check was never run.
2) The neighbor table lookup used the IPv6 header destination, which is the
	solicited node address, rather than the target address from the
	neighbor solicitation. So neighbor lookups would always fail if it
	got this far. Also for L3MISSes.
3) The code calls ndisc_send_na(), which does a send on the tunnel device.
	The context for neigh_reduce() is the transmit path, vxlan_xmit(),
	where the host or a bridge-attached neighbor is trying to transmit
	a neighbor solicitation. To respond to it, the tunnel endpoint needs
	to do a *receive* of the appropriate neighbor advertisement. Doing a
	send, would only try to send the advertisement, encapsulated, to the
	remote destinations in the fdb -- hosts that definitely did not do the
	corresponding solicitation.
4) The code uses the tunnel endpoint IPv6 forwarding flag to determine the
	isrouter flag in the advertisement. This has nothing to do with whether
	or not the target is a router, and generally won't be set since the
	tunnel endpoint is bridging, not routing, traffic.

	The patch below creates a proxy neighbor advertisement to respond to
neighbor solicitions as intended, providing proper IPv6 support for neighbor
reduction.

net: davinci_emac: Fix interrupt requests and error handling

since commit 6892b41d (Linux 3.11) the
davinci_emac driver is broken. After doing ifconfig down, ifconfig up,
requesting the interrupts for the driver fails. The interface remains dead
until the board is rebooted.

The first patch in this patchset reverts commit
6892b41d partially and makes the driver
useable again.

During the work on the first patch, a number of bugs in the error handling
of the driver's ndo_open code were found. The second patch fixes these bugs.

I believe the first patch meets the rules for stable kernels, I therefore added
the stable tag to this patch. The second patch is just cleanup, the code
that is fixed by this patch is only executed in case of an error.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

If an error occurs during the initialization in emac_dev_open() (the
driver's ndo_open function), interrupts, DMA descriptors etc. must be freed.
The current rollback code is buggy in several ways.

  1) Freeing the interrupts. The current code will not free all interrupts
     that were requested by the driver. Furthermore,  the code tries to do a
     platform_get_resource(priv->pdev, IORESOURCE_IRQ, -1) in its last
     iteration.

     This patch fixes these bugs.

  2) Wrong order of err: and rollback: labels. If the setup of the PHY in
     the code fails, the interrupts that have been requested before are
     not freed:

        request irq
                if requesting irqs fails, goto rollback
        setup phy
                if phy setup fails, goto err
        return 0

     rollback:
        free irqs
     err:

     This patch brings the code into the correct order.

  3) The code calls napi_enable() and emac_int_enable(), but does not
     undo both in case of an error.

     This patch adds calls of emac_int_disable() and napi_disable() to the
     rollback code.

  4) RX DMA descriptors are not freed in case of an error: Right before
     requesting the irqs, the function creates DMA descriptors for the
     RX channel. These RX descriptors are never freed when we jump to either
     rollback or err.

     This patch adds code for freeing the DMA descriptors in the case of
     an initialization error. This required a modification of
     cpdma_ctrl_stop() in davinci_cpdma.c: We must be able to call this
     function to free the DMA descriptors while the DMA channels are
     in IDLE state (before cpdma_ctlr_start() was called).

Tested on a custom board with the Texas Instruments AM1808.

net: davinci: emac: Convert to devm_* api

the call of request_irq is replaced by devm_request_irq and the call
of free_irq is removed. But since interrupts are requested in
emac_dev_open, doing ifconfig up/down on the board requests the
interrupts again each time, causing devm_request_irq to fail. The
interface is dead until the device is rebooted.

This patch reverts said commit partially: It changes the driver back
to use request_irq instead of devm_request_irq, puts free_irq back in
place, but keeps the remaining changes of the original patch.

   * so jiffies wrap bugs show up earlier.
   */
  #define INITIAL_JIFFIES ((unsigned long)(unsigned int) (-300*HZ))

The loop in ovs_flow_stats_get() starts out with 'used' set to 0, then
takes any "later" time.  This means that for the first five minutes after
boot, flows will always be reported as never used, since 0 is greater than
any time already seen.

 "Three of these are regression fixes, for two recent regressions and
  one introduced during the 3.13 cycle, and the fourth one is a working

  Specifics:

   - A recent ACPI resources handling fix overlooked the fact that it
     had to update the ACPI PNP subsystem's resources parsing too and
     caused confusing warning messages to be printed during system
     intialization on some systems (with arguably buggy ACPI tables).
     Fix from Zhang Rui.

   - Moving the early ACPI initialization before timekeeping_init()
     earlier in this cycle broke fast TSC calibration on at least one
     system, so it needs to be done later, but still before
     efi_enter_virtual_mode() to allow the EFI initialization to refer
     to ACPI.

   - A change related to code duplication reduction in the cpufreq core
     inadvertently caused cpufreq intialization to fail for some CPUs
     handled by intel_pstate by adding checks that may fail for that
     driver, but aren't even necessary when it is used.  The issue is
     addressed by preventing those checks from run in the configurations
     in which they aren't needed.

   - If the Hardware Reduced ACPI flag is set in the ACPI tables, system
     suspend, hibernation and ACPI power off will only work when special
     sleep control and sleep status registeres are provided (their
     addresses in the ACPI tables are not zero).  If those registers are
     not available, the features in question have no chances to work, so
     they shouldn't even be regarded as supported.  That helps with
     power off in particular, because alternative power off methods may
     be used then and they may actually work"

using the node reported from the PCI bus. For single-fabric
systems, the northbriges are on PCI bus 0 by definition, which
are on NUMA node 0 by definition, so this is invarient on most
systems.

Tested on fam10h and fam15h single and multi-fabric systems and
candidate for stable.

Pull networking fixes from David Miller:
 "I know this is a bit more than you want to see, and I've told the
  wireless folks under no uncertain terms that they must severely scale
  back the extent of the fixes they are submitting this late in the
  game.

  Anyways:

   1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
      is the correct implementation, like it should.  Instead it does
      something like a NAPI poll operation.  This leads to crashes.

      From Neil Horman and Arnd Bergmann.

   2) Segmentation of SKBs requires proper socket orphaning of the
      fragments, otherwise we might access stale state released by the
      release callbacks.

      This is a 5 patch fix, but the initial patches are giving
      variables and such significantly clearer names such that the
      actual fix itself at the end looks trivial.

      From Michael S.  Tsirkin.

   3) TCP control block release can deadlock if invoked from a timer on
      an already "owned" socket.  Fix from Eric Dumazet.

   4) In the bridge multicast code, we must validate that the
      destination address of general queries is the link local all-nodes
      multicast address.  From Linus Lüssing.

   5) The x86 BPF JIT support for negative offsets puts the parameter
      for the helper function call in the wrong register.  Fix from
      Alexei Starovoitov.

   6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
      r8169 driver is incorrect.  Fix from Hayes Wang.

   7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
      if a packet is a GSO frame, but that's not the correct test.  It
      should use skb_is_gso(skb) instead.  Fix from Wei Liu.

   8) Negative msg->msg_namelen values should generate an error, from
      Matthew Leach.

   9) at86rf230 can deadlock because it takes the same lock from it's
      ISR and it's hard_start_xmit method, without disabling interrupts
      in the latter.  Fix from Alexander Aring.

  10) The FEC driver's restart doesn't perform operations in the correct
      order, so promiscuous settings can get lost.  Fix from Stefan
      Wahren.

  11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.

  12) Reference count and memory leak fixes in TIPC from Ying Xue and
      Erik Hugne.

  13) Forced eviction in inet_frag_evictor() must strictly make sure all
      frags are deleted, otherwise module unload (f.e.  6lowpan) can
      crash.  Fix from Florian Westphal.

  14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
      uses as a hash function), which breaks on PowerPC.  From Anton
      Blanchard.

      The main gist of the issue is that csum_partial() is defined only
      as a value that, once folded (f.e.  via csum_fold()) produces a
      correct 16-bit checksum.  It is legitimate, therefore, for
      csum_partial() to produce two different 32-bit values over the
      same data if their respective alignments are different.

  15) Fix endiannes bug in MAC address handling of ibmveth driver, also
      from Anton Blanchard.

  16) Error checks for ipv6 exthdrs offload registration are reversed,
      from Anton Nayshtut.

  17) Externally triggered ipv6 addrconf routes should count against the
      garbage collection threshold.  Fix from Sabrina Dubroca.

  18) The PCI shutdown handler added to the bnx2 driver can wedge the
      chip if it was not brought up earlier already, which in particular
      causes the firmware to shut down the PHY.  Fix from Michael Chan.

  19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
      currently coded it can and does trigger in legitimate situations.
      From Eric Dumazet.

  20) BNA driver fails to build on ARM because of a too large udelay()
      call, fix from Ben Hutchings.

  21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
      from Eric Dumazet.

  22) The vlan passthrough ops added in the previous release causes a
      regression in source MAC address setting of outgoing headers in
      some circumstances.  Fix from Peter Boström"
