Dmitry Fleytman c5d083c561 NetRxPkt: Account buffer with ETH header in IOV length
In case of VLAN stripping ETH header is stored in a
separate chunk and length of IOV should take this into
account.

This patch fixes checksum validation for RX packets
with VLAN header.

Devices affected by this problem: e1000e and vmxnet3.

Dmitry Fleytman d5e772146d NetRxPkt: Do not try to pull more data than present
In case of VLAN stripping, ETH header put into a
separate buffer, therefore amont of data copied
from original IOV should be smaller.

Dmitry Fleytman df8bf7a7fe NetRxPkt: Fix memory corruption on VLAN header stripping
This patch fixed a problem that was introduced in commit eb700029.

When net_rx_pkt_attach_iovec() calls eth_strip_vlan()
this can result in pkt->ehdr_buf being overflowed, because
ehdr_buf is only sizeof(struct eth_header) bytes large
but eth_strip_vlan() can write
sizeof(struct eth_header) + sizeof(struct vlan_header)
bytes into it.

Devices affected by this problem: vmxnet3.

Sam Bobroff 87684b4c40 hw/net/spapr_llan: 6 byte mac address device tree entry
The spapr-vlan device in QEMU has always presented it's MAC address in
the device tree as an 8 byte value, even though PAPR requires it to be
6 bytes.  This is because, at the time, AIX required the value to be 8
bytes.  However, modern versions of AIX support the (correct) 6
byte value so they no longer require the workaround.

It would be neatest to always provide a 6 byte value but that would
cause a problem with old Linux kernel ibmveth drivers, so the old 8
byte value is still presented when necessary.

Since commit 13f85203e (3.10, May 2013) the driver has been able to
handle 6 or 8 byte addresses so versions after that don't need to be
considered specially.

Drivers from kernels before that can also handle either type of
address, but not always:
* If the first byte's lowest bits are 10, the address must be 6 bytes.
* Otherwise, the address must be 8 bytes.
(The two bits in question are significant in a MAC address: they
indicate a locally-administered unicast address.)

So to maintain compatibility the old 8 byte value is presented when
the lowest two bits of the first byte are not 10.

Halil Pasic 59046ec29a migration: consolidate VMStateField.start
The member VMStateField.start is used for two things, partial data
migration for VBUFFER data (basically provide migration for a
sub-buffer) and for locating next in QTAILQ.

The implementation of the VBUFFER feature is broken when VMSTATE_ALLOC
is used. This however goes unnoticed because actually partial migration
for VBUFFER is not used at all.

Let's consolidate the usage of VMStateField.start by removing support
for partial migration for VBUFFER.

it's used in realize().  The same issue was fixed for msi_init() in
commit 1108b2f. In order to make the API change as small as possible,
leave the return value check to later patch.

For some devices(like e1000e, vmxnet3, nvme) who won't fail because of
msix_init's failure, suppress the error report by passing NULL error
object.

Bonus: add comment for msix_init.

Introduce rules in the top level Makefile that are able to generate
trace.[ch] files in every subdirectory which has a trace-events file.

The top level directory is handled specially, so instead of creating
trace.h, it creates trace-root.h. This allows sub-directories to
include the top level trace-root.h file, without ambiguity wrt to
the trace.g file in the current sub-dir.

Michael Davidsaver d05a86285c arm: stellaris: make MII accesses complete immediately
When the guest attempts to start an MII register
access via the MCTL register, clear the START bit,
so that when the guest reads it back the register
transaction will be signalled as having completed.
This avoids the guest spinning as it polls the
START bit waiting for it to clear (which it
previously never would).

The  MII registers themselves still aren't implemented,
but at least we can avoid guests spending quite so much
time busy waiting.

Dr. David Alan Gilbert 20daa90a20 PCI/migration merge vmstate_pci_device and vmstate_pcie_device
The vmstate_pci_device and vmstate_pcie_devices differ
just in the size of one buffer; combine the two using a _TEST
macro.

I think this is safe as long as everywhere which currently
uses either of these two uses the right type.

One thing that concerns me is that some places use pci_device_load/save
which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE
macro - how are they getting the same irq mangling?

This passes a smoke test migrate of:
./x86_64-softmmu/qemu-system-x86_64 -M pc,accel=kvm -m 1024
./littlefed20.img -device e1000e -device virtio-net -device

Peter Maydell 581f7b127d hw/net/dp8393x: Avoid unintentional sign extensions on addresses
The dp8393x has several 32-bit values which are formed by concatenating
two 16 bit device register values. Attempting to do these inline
with ((s->reg[HI] << 16) | s->reg[LO]) can result in an unintended
sign extension because "x << 16" is of type 'int' even though s->reg
is unsigned, and so if the expression is used in a context where
it is cast to uint64_t the value is incorrectly sign-extended.
Fix this by using accessor functions with a uint32_t return type;
this also makes the code a bit easier to read.

This should fix Coverity issues 1307765, 1307766, 1307767, 1307768.

(To avoid having a ctda read function only used in a DPRINTF,
we move the DPRINTF down slightly so it can use the ttda function.)

simply "-net nic -net user"), there is currently a confusing warning
message saying:

 Warning: requested NIC (anonymous, model mcf_fec) was not created

This seems to happen because the MCF NIC has never been adapted to
the currently expected QEMU device behavior. Thus let's QOMify the
NIC now to get rid of the warning message.

Jason Wang c471ad0e9b vhost_net: device IOTLB support
This patches implements Device IOTLB support for vhost kernel. This is
done through:

1) switch to use dma helpers when map/unmap vrings from vhost codes
2) introduce a set of VhostOps to:
   - setting up device IOTLB request callback
   - processing device IOTLB request
   - processing device IOTLB invalidation
2) kernel support for Device IOTLB API:

- allow vhost-net to query the IOMMU IOTLB entry through eventfd
- enable the ability for qemu to update a specified mapping of vhost
- through ioctl.
- enable the ability to invalidate a specified range of iova for the
  device IOTLB of vhost through ioctl. In x86/intel_iommu case this is
  triggered through iommu memory region notifier from device IOTLB
  invalidation descriptor processing routine.

With all the above, kernel vhost_net can co-operate with userspace
IOMMU. For vhost-user, the support could be easily done on top by
implementing the VhostOps.

Yuri Benditovich 283e2c2adc net: virtio-net discards TX data after link down
https://bugzilla.redhat.com/show_bug.cgi?id=1295637
Upon set_link monitor command or upon netdev deletion
virtio-net sends link down indication to the guest
and stops vhost if one is used.
Guest driver can still submit data for TX until it
recognizes link loss. If these packets not returned by
the host, the Windows guest will never be able to finish
disable/removal/shutdown.
Now each packet sent by guest after NIC indicated link
down will be completed immediately.

Andrey Smirnov 7e354ed4df fsl_etsec: Fix Tx BD ring wrapping handling
Current code that handles Tx buffer desciprtor ring scanning employs the
following algorithm:

	1. Restore current buffer descriptor pointer from TBPTRn

	2. Process current descriptor

	3. If current descriptor has BD_WRAP flag set set current
	   descriptor pointer to start of the descriptor ring

	4. If current descriptor points to start of the ring exit the
	   loop, otherwise increment current descriptor pointer and go
	   to #2

	5. Store current descriptor in TBPTRn

The way the code is implemented results in buffer descriptor ring being
scanned starting at offset/descriptor #0. While covering 99% of the
cases, this algorithm becomes problematic for a number of edge cases.

Consider the following scenario: guest OS driver initializes descriptor
ring to N individual descriptors and starts sending data out. Depending
on the volume of traffic and probably guest OS driver implementation it
is possible that an edge case where a packet, spread across 2
descriptors is placed in descriptors N - 1 and 0 in that order(it is
easy to imagine similar examples involving more than 2 descriptors).

What happens then is aforementioned algorithm starts at descriptor 0,
sees a descriptor marked as BD_LAST, which it happily sends out as a
separate packet(very much malformed at this point) then the iteration
continues and the first part of the original packet is tacked to the
next transmission which ends up being bogus as well.

This behvaiour can be pretty reliably observed when scp'ing data from a
guest OS via TAP interface for files larger than 160K (every time for
700K+).

This patch changes the scanning algorithm to do the following:

	1. Restore "current" buffer descriptor pointer from
	   TBPTRn

	2. If "current" descriptor does not have BD_TX_READY set, goto #6

	3. Process current descriptor

	4. If "current" descriptor has BD_WRAP flag set "current"
	   descriptor pointer to start of the descriptor ring otherwise
	   set increment "current" by the size of one descriptor

	5. Goto #1

	6. Save "current" buffer descriptor in TBPTRn

This way we preserve the information about which descriptor was
processed last and always start where we left off avoiding the original
problem. On top of that, judging by the following excerpt from
MPC8548ERM (p. 14-48):

"... When the end of the TxBD ring is reached, eTSEC initializes TBPTRn
to the value in the corresponding TBASEn. The TBPTR register is
internally written by the eTSEC’s DMA controller during
transmission. The pointer increments by eight (bytes) each time a
descriptor is closed successfully by the eTSEC..."

revised algorithm might also a more correct way of emulating this aspect
of eTSEC peripheral.

Andrey Smirnov 64f441d2e5 fsl_etsec: Pad short payloads with zeros
Depending on QEMU network setup it is possible for us to receive a
complete Ethernet packet that is less 64 bytes long. One such example is
when QEMU is configured to use a standalone TAP device (not set to be a
part of any bridge) receives and ARP packet. In cases like that we need
to add more than just 4-bytes of CRC padding and ensure that our payload
is at least 60 bytes long, such that, when combined with CRC padding
bytes the resulting size is at least 802.3 minimum MTU bytes
long (64). Failing to do that results in code in etsec_walk_rx_ring()
setting BD_RX_SH which, in turn, makes corresponding Linux driver of
emulated host to reject buffer as a runt packet

Kevin Wolf c89d416a2b e1000e: Don't zero out buffer address in rx descriptor
The e1000e emulation zeroes out any used rx descriptor and then writes a
completely newly constructed value there. By doing this, it doesn't only
update the write-back area of the descriptors (as it's supposed to do),
but it also clears the buffer address, which real hardware doesn't do.

The spec explicitly mentions in chapter 7.1.8 that it is valid for a
driver to reuse a descriptor and only update the status field while
doing so, i.e. reusing the old buffer address:

    If software statically allocates buffers, and uses memory read to
    check for completed descriptors, it simply has to zero the status
    byte in the descriptor to make it ready for reuse by hardware.

This patch fixes the behaviour to leave the buffer address in
descriptors unchanged even after the descriptor has been used.

Michael S. Tsirkin 1c0fbfa3de virtio-net: allow increasing rx queue size
This allows increasing the rx queue size up to 1024: unlike with tx,
guests don't put in huge S/G lists into RX so the risk of running into
the max 1024 limitation due to some off-by-one seems small.

It's helpful for users like OVS-DPDK which don't do any buffering on the
host - 1K roughly matches 500 entries in tun + 256 in the current rx
queue, which seems to work reasonably well. We could probably make do
with ~750 entries but virtio spec limits us to powers of two.
It might be a good idea to specify an s/g size limit in a future
version.

It also might be possible to make the queue size smaller down the road, 64
seems like the minimal value which will still work (as guests seem to
assume a queue full of 1.5K buffers is enough to process the largest
incoming packet, which is ~64K).  No one actually asked for this, and
with virtio 1 guests can reduce ring size without need for host
configuration, so don't bother with this for now.

This pull request supersedes ppc-for-2.8-20160922.  There was a clang
 build error in that, and I've also added one extra patch in the new pull.
 
 Included in this set of ppc and spapr patches are:
     * TCG implementations for more POWER9 instructions
     * Some preliminary XICS fixes in preparataion for the pnv machine type
     * A significant ADB (Macintosh kbd/mouse) cleanup
     * Some conversions to use trace instead of debug macros
     * Fixes to correctly handle global TLB flush synchronization in
       TCG.  This is already a bug, but it will have much more impact
       when we get MTTCG
     * Add more qtest testcases for Power
     * Some MAINTAINERS updates
     * Assorted bugfixes
     * Add the basics of NUMA associativity to the spapr PCI host bridge
 
 This touches some test files and monitor.c which are technically
 outside the ppc code, but coming through this tree because the changes
 are primarily of interest to ppc.

Marc-André Lureau e6bcb1b617 vhost-user: keep vhost_net after a disconnection
Many code paths assume get_vhost_net() returns non-null.

Keep VhostUserState.vhost_net after a successful vhost_net_init(),
instead of freeing it in vhost_net_cleanup().

VhostUserState.vhost_net is thus freed before after being recreated or
on final vhost_user_cleanup() and there is no need to save the acked
features.

Marc-André Lureau f1a0365b68 vhost-net: always call vhost_dev_cleanup() on failure
vhost_dev_init(), calling vhost backend initialization, should be
cleaned up after failure too. Call vhost_dev_cleanup() in all failure
cases. First, it needs to zero-alloc the struct to avoid the initial
garbage.

Eric Blake f394b2e20d qapi: Change Netdev into a flat union
This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union.  The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.

While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place.  Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two.  Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

Based on an idea originally by Zoltán Kővágó <DirtY.iCE.hu@gmail.com>:
Message-Id: <01a527fbf1a5de880091f98cf011616a78adeeee.1441627176.git.DirtY.iCE.hu@gmail.com>
although the sed script in that patch no longer applies due to
other changes in the tree since then, and I also did some manual
cleanups (such as fixing whitespace to keep checkpatch happy).
