    net: pcnet: add check to validate receive data size(CVE-2015-7504)

    In loopback mode, pcnet_receive routine appends CRC code to the
    receive buffer. If the data size given is same as the buffer size,
    the appended CRC code overwrites 4 bytes after s->buffer. Added a
    check to avoid that.

    When processing NCQ commands, AHCI device emulation prepares a
    NCQ transfer object; To which an aio control block(aiocb) object
    is assigned in 'execute_ncq_command'. In case, when the NCQ
    command is invalid, the 'aiocb' object is not assigned, and NCQ
    transfer object is left as 'used'. This leads to a use after
    free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
    Reset NCQ transfer object to 'unused' to avoid it.

    e1000: eliminate infinite loops on out-of-bounds transfer start

    The start_xmit() and e1000_receive_iov() functions implement DMA transfers
    iterating over a set of descriptors that the guest's e1000 driver
    prepares:

    - the TDLEN and RDLEN registers store the total size of the descriptor
      area,

    - while the TDH and RDH registers store the offset (in whole tx / rx
      descriptors) into the area where the transfer is supposed to start.

    Each time a descriptor is processed, the TDH and RDH register is bumped
    (as appropriate for the transfer direction).

    QEMU already contains logic to deal with bogus transfers submitted by the
    guest:

    - Normally, the transmit case wants to increase TDH from its initial value
      to TDT. (TDT is allowed to be numerically smaller than the initial TDH
      value; wrapping at or above TDLEN bytes to zero is normal.) The failsafe
      that QEMU currently has here is a check against reaching the original
      TDH value again -- a complete wraparound, which should never happen.

    - In the receive case RDH is increased from its initial value until
      "total_size" bytes have been received; preferably in a single step, or
      in "s->rxbuf_size" byte steps, if the latter is smaller. However, null
      RX descriptors are skipped without receiving data, while RDH is
      incremented just the same. QEMU tries to prevent an infinite loop
      (processing only null RX descriptors) by detecting whether RDH assumes
      its original value during the loop. (Again, wrapping from RDLEN to 0 is
      normal.)

    What both directions miss is that the guest could program TDLEN and RDLEN
    so low, and the initial TDH and RDH so high, that these registers will
    immediately be truncated to zero, and then never reassume their initial
    values in the loop -- a full wraparound will never occur.

    The condition that expresses this is:

      xdh_start >= s->mac_reg[XDLEN] / sizeof(desc)

    i.e., TDH or RDH start out after the last whole rx or tx descriptor that
    fits into the TDLEN or RDLEN sized area.

    This condition could be checked before we enter the loops, but
    pci_dma_read() / pci_dma_write() knows how to fill in buffers safely for
    bogus DMA addresses, so we just extend the existing failsafes with the
    above condition.

    This is CVE-2016-1981.

    xen: fix usage of xc_domain_create in domain builder

    Due to the addition of HVMlite and the requirement to always provide a
    valid xc_domain_configuration_t, xc_domain_create now always takes an arch
    domain config, which can be NULL in order to mimic previous behaviour.

    Add a small stub called xen_domain_create that encapsulates the correct
    call to xc_domain_create depending on the libxc version detected.
