8dfd5f9651 io: get rid of bounce buffering in websock write path
Currently most outbound I/O on the websock channel gets copied into the
rawoutput buffer, and then immediately copied again into the encoutput
buffer, with a header prepended. Now that qio_channel_websock_encode
accepts a struct iovec, we can trivially remove this bounce buffering
and write directly to encoutput.

In doing so, we also now correctly validate the encoutput size against
the QIO_CHANNEL_WEBSOCK_MAX_BUFFER limit.

bac6c95415 io: get rid of qio_channel_websock_encode helper method
The qio_channel_websock_encode method is only used in one place,
everything else calls qio_channel_websock_encode_buffer directly.
It can also be pushed up a level into the qio_channel_websock_writev
method, since every other caller of qio_channel_websock_write_wire
has already filled encoutput.

57b0cdf152 io: simplify websocket ping reply handling
We must ensure we don't get flooded with ping replies if the outbound
channel is slow. Currently we do this by keeping the ping reply in a
separate temporary buffer and only writing it if the encoutput buffer
is completely empty. This is overly pessimistic, as it is reasonable
to add a ping reply to the encoutput buffer even if it has previous
data in it, as long as that previous data doesn't include a ping
reply.

To track this better, put the ping reply directly into the encoutput
buffer, and then record the size of encoutput at this time in
pong_remain. As we write encoutput to the underlying channel, we
can decrement the pong_remain counter. Once it hits zero, we can
accept further ping replies for transmission.

a7b20a8efa io: monitor encoutput buffer size from websocket GSource
The websocket GSource is monitoring the size of the rawoutput
buffer to determine if the channel can accepts more writes.
The rawoutput buffer, however, is merely a temporary staging
buffer before data is copied into the encoutput buffer. Thus
its size will always be zero when the GSource runs.

This flaw causes the encoutput buffer to grow without bound
if the other end of the underlying data channel doesn't
read data being sent. This can be seen with VNC if a client
is on a slow WAN link and the guest OS is sending many screen
updates. A malicious VNC client can act like it is on a slow
link by playing a video in the guest and then reading data
very slowly, causing QEMU host memory to expand arbitrarily.

This issue is assigned CVE-2017-15268, publically reported in

9cf961bba7 sockets: Handle race condition between binds to the same port
If an offset of ports is specified to the inet_listen_saddr function(),
and two or more processes tries to bind from these ports at the same time,
occasionally more than one process may be able to bind to the same
port. The condition is detected by listen() but too late to avoid a failure.

This function is called by socket_listen() and used
by all socket listening code in QEMU, so all cases where any form of dynamic
port selection is used should be subject to this issue.

Add code to close and re-establish the socket when this
condition is observed, hiding the race condition from the user.

Also clean up some issues with error handling to allow more
accurate reporting of the cause of an error.

This has been developed and tested by means of the
test-listen unit test in the previous commit.
Enable the test for make check now that it passes.

2ff408de9c gtk: fix wrong id between texture and framebuffer
The gd_gl_area_scanout_texture must destroy framebuffer if there is
no texture id instead of no framebuffer id.
The effect was a black screen with "-vga virtio -display gtk,gl=on"
options.
The bug was introduce by a4f113fd "gtk: use framebuffer helper functions."

bcd5ac9bcb ui: convert common input code to keycodemapdb
Replace the number_to_qcode, qcode_to_number and linux_to_qcode
tables with automatically generated tables.

Missing entries in linux_to_qcode now fixed:

  KEY_LINEFEED -> Q_KEY_CODE_LF
  KEY_KPEQUAL -> Q_KEY_CODE_KP_EQUALS
  KEY_COMPOSE -> Q_KEY_CODE_COMPOSE
  KEY_AGAIN -> Q_KEY_CODE_AGAIN
  KEY_PROPS -> Q_KEY_CODE_PROPS
  KEY_UNDO -> Q_KEY_CODE_UNDO
  KEY_FRONT -> Q_KEY_CODE_FRONT
  KEY_COPY -> Q_KEY_CODE_COPY
  KEY_OPEN -> Q_KEY_CODE_OPEN
  KEY_PASTE -> Q_KEY_CODE_PASTE
  KEY_CUT -> Q_KEY_CODE_CUT
  KEY_HELP -> Q_KEY_CODE_HELP
  KEY_MEDIA -> Q_KEY_CODE_MEDIASELECT

In addition, some fixes:

 - KEY_PLAYPAUSE now maps to Q_KEY_CODE_AUDIOPLAY, instead of
   KEY_PLAYCD. KEY_PLAYPAUSE is defined across almost all scancodes
   sets, while KEY_PLAYCD only appears in AT set1, so the former is
   a more useful mapping.

Missing entries in qcode_to_number now fixed:

  Q_KEY_CODE_AGAIN -> 0x85
  Q_KEY_CODE_PROPS -> 0x86
  Q_KEY_CODE_UNDO -> 0x87
  Q_KEY_CODE_FRONT -> 0x8c
  Q_KEY_CODE_COPY -> 0xf8
  Q_KEY_CODE_OPEN -> 0x64
  Q_KEY_CODE_PASTE -> 0x65
  Q_KEY_CODE_CUT -> 0xbc
  Q_KEY_CODE_LF -> 0x5b
  Q_KEY_CODE_HELP -> 0xf5
  Q_KEY_CODE_COMPOSE -> 0xdd
  Q_KEY_CODE_KP_EQUALS -> 0x59
  Q_KEY_CODE_MEDIASELECT -> 0xed

In addition, some fixes:

 - Q_KEY_CODE_MENU was incorrectly mapped to the compose
   scancode (0xdd) and is now mapped to 0x9e
 - Q_KEY_CODE_FIND was mapped to 0xe065 (Search) instead
   of to 0xe041 (Find)
 - Q_KEY_CODE_HIRAGANA was mapped to 0x70 (Katakanahiragana)
   instead of of 0x77 (Hirigana)
 - Q_KEY_CODE_PRINT was mapped to 0xb7 which is not a defined
   scan code in AT set 1, it is now mapped to 0x54 (sysrq)

927128222b ui: add keycodemapdb repository as a GIT submodule
The https://gitlab.com/keycodemap/keycodemapdb/ repo contains a
data file mapping between all the different scancode/keycode/keysym
sets that are known, and a tool to auto-generate lookup tables for
different combinations.

It is used by GTK-VNC, SPICE-GTK and libvirt for mapping keys.
Using it in QEMU will let us replace many hand written lookup
tables with auto-generated tables from a master data source,
reducing bugs. Adding new QKeyCodes will now only require the
master table to be updated, all ~20 other tables will be
automatically updated to follow.

47bb908dd1 docker: don't rely on submodules existing in the main checkout
When building the tarball to pass into the docker/vm test image,
the code relies on the git submodules being checked out in the
main checkout.

ie if the developer has not run 'git submodule update --init dtc'
many of the docker tests will fail due to the libfdt package not
being present in the test images. Patchew manually checks out the
dtc submodule in the main git checkout, but this is a bad idea.

When running tests we want to have a predictable set of submodules
included in the source that's tested. The build environment is
completely independent of the developers host OS, so the submodules
the developer has checked out should not be considered relevant for
the tests.

This changes the archive-source.sh script so that it clones the
current git checkout into a temporary directory, checks out a
fixed set of submodules, builds the tarball and finally removes
the temporary git clone.

aef45d51d1 build: automatically handle GIT submodule checkout for dtc
Currently if DTC is required by configure and not available in the host
OS install, we exit with an error message telling the user to checkout a
git submodule or install the library.

This introduces automatic handling of the git submodule checkout process
and enables it for dtc. This only runs if building from GIT, so users of
release tarballs still need the system library install. The current state
of the git checkout is stashed in .git-submodule-status, and a helper
program is used to determine if this state matches the desired submodule
state. A dependency against 'Makefile' ensures that the submodule state
is refreshed at the start of the build process

[vmxnet3][WR][vmxnet3_pci_realize]: Failed to initialize MSI-X, configuration is inconsistent.

Since vmxnet3 is a para-virtualized device that is only useful on x86,
it should also only be enabled on the x86 targets.

b95b5a0a52 tests/prom-env: Bump the timeout, and test pseries only in slow mode
If QEMU has been compiled with the flags --enable-tcg-interpreter and
--enable-debug, the guest is running incredibly slow. The prom-env
test is approximately 10 times slower than normal in this case, and
it takes up to 500 seconds until the test with the pseries machine
finishs. While we should still look for ways to speed up the test
on the pseries machine here, let's bump the timeout to 600 seconds to
allow the test to pass with this unusal configuration already now.
Also move the pseries test into the "slow" category - since it is
really a very slow test.

ab06ec4357 tests/pxe: Test more NICs when running in SPEED=slow mode
The pxe-test is a very good test to excercise NICs, thus we should use
it to test all NICs that can be used by the BIOS for booting via network.
However, to avoid that the default testing time increases too much, the
additional NICs are only tested in the "make check SPEED=slow" mode.

The virtio-net NIC on ppc64 is now also only tested in slow mode, since
the test on ppc64 is really quite slow and we've got test coverage for
virtio-net in big endian mode now on s390x, too.

get even worse when there are dozens or hundreds of virtio-pci devices -
since these address spaces are global, changing any of them triggers
rebuilding all address spaces.

This replaces indirect accesses to the modern BAR with a simple lookup
and direct calls to memory_region_dispatch_read/write.

This is expected to save lots of memory at boot time after applying:

37ef70be6a virtio: fix descriptor counting in virtqueue_pop
While changing the s/g list allocation, commit 3b3b0628
also changed the descriptor counting to count iovec entries
as split by cpu_physical_memory_map(). Previously only the
actual descriptor entries were counted and the split into
the iovec happened afterwards in virtqueue_map().
Count the entries again instead to avoid erroneous
"Looped descriptor" errors.

fd3b02c889 pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:

1) The ones that already have INTERFACE_PCIE_DEVICE set:

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3

2) base-pci-bridge

Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:

* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge

The direct subtypes of base-pci-bridge not touched by this patch
are:

* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
  marked as PCIe-only devices.

3) megasas-base

Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.

"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

a5fa336f11 pci: Add interface names to hybrid PCI devices
The following devices support both PCI Express and Conventional
PCI, by including special code to handle the QEMU_PCI_CAP_EXPRESS
flag and/or conditional pcie_endpoint_cap_init() calls:

* vfio-pci (is_express=1, but legacy PCI handled by
  vfio_populate_device())
* vmxnet3 (is_express=0, but PCIe handled by vmxnet3_realize())
* pvscsi (is_express=0, but PCIe handled by pvscsi_realize())
* virtio-pci (is_express=0, but PCIe handled by
  virtio_pci_dc_realize(), and additional legacy PCI code at
  virtio_pci_realize())
* base-xhci (is_express=1, but pcie_endpoint_cap_init() call
  is conditional on pci_bus_is_express(dev->bus)
  * Note that xhci does not clear QEMU_PCI_CAP_EXPRESS like the
    other hybrid devices
