In my investigation, ZRLE always compresses better than ZLIB so
prioritize ZRLE over ZLIB, even if the client hints that ZLIB is
preferred.
zlib buffer is always reset in zrle_compress_data(), so using offset to
calculate next_out and avail_out is useless.

This reverts commit de3f7de7f4.
Remove VNC optimization to reencode framebuffer update as raw if it's
smaller than the default encoding.
QEMU's implementation was naive and didn't account for the ZLIB z_stream
mutating with each compression. Because of the mutation, simply
resetting the output buffer's offset wasn't sufficient to "rewind" the
operation. The mutated z_stream would generate future zlib blocks which
referred to symbols in past blocks which weren't sent. This would lead
to artifacting.
Considering that ZRLE is never larger than raw and even though ZLIB can
occasionally be fractionally larger than raw, the overhead of
implementing this optimization correctly isn't worth it.

GTK+ provides convenient definition in <gdk/gdkversionmacros.h>
(already include by <gdk/gdk.h>) to check which API are available.
We only use the GdkMonitor API to get the monitor refresh rate.
Extract this code as a new gd_refresh_rate_millihz() function,
and check GDK_VERSION_3_22 is defined before calling its API.
If it is not defined, return 0. This is safe and fixes our build

Because some VMs in QEMU can get GPU virtualization (using technologies
such as iGVT-g, as mentioned previously), they could produce a video
output that had a higher display refresh rate than of what the GTK
display was displaying. (fxp. Playing a video game inside of a Windows
VM at 60 Hz, while the output stood locked at 33 Hz because of defaults
set in include/ui/console.h)
Since QEMU does indeed have internal systems for determining frame
times as defined in ui/console.c.
The code checks for a variable called update_interval that it later
uses for time calculation. This variable, however, isn't defined
anywhere in ui/gtk.c and instead ui/console.c just sets it to
GUI_REFRESH_INTERVAL_DEFAULT which is 30
update_interval represents the number of milliseconds per display
refresh, and by doing some math we get that 1000/30 = 33.33... Hz
This creates the mentioned problem and what this patch does is that it
checks for the display refresh rate reported by GTK itself (we can take
this as a safe value) and just converts it back to a number of
milliseconds per display refresh.

Currently when qemu receives a vnc connect, it creates a 'VncState' to
represent this connection. In 'vnc_worker_thread_loop' it creates a
local 'VncState'. The connection 'VcnState' and local 'VncState' exchange
data in 'vnc_async_encoding_start' and 'vnc_async_encoding_end'.
In 'zrle_compress_data' it calls 'deflateInit2' to allocate the libz library
opaque data. The 'VncState' used in 'zrle_compress_data' is the local
'VncState'. In 'vnc_zrle_clear' it calls 'deflateEnd' to free the libz
library opaque data. The 'VncState' used in 'vnc_zrle_clear' is the connection
'VncState'. In currently implementation there will be a memory leak when the
vnc disconnect. Following is the asan output backtrack:
Direct leak of 29760 byte(s) in 5 object(s) allocated from:
0 0xffffa67ef3c3 in __interceptor_calloc (/lib64/libasan.so.4+0xd33c3)
1 0xffffa65071cb in g_malloc0 (/lib64/libglib-2.0.so.0+0x571cb)
2 0xffffa5e968f7 in deflateInit2_ (/lib64/libz.so.1+0x78f7)
3 0xaaaacec58613 in zrle_compress_data ui/vnc-enc-zrle.c:87
4 0xaaaacec58613 in zrle_send_framebuffer_update ui/vnc-enc-zrle.c:344
5 0xaaaacec34e77 in vnc_send_framebuffer_update ui/vnc.c:919
6 0xaaaacec5e023 in vnc_worker_thread_loop ui/vnc-jobs.c:271
7 0xaaaacec5e5e7 in vnc_worker_thread ui/vnc-jobs.c:340
8 0xaaaacee4d3c3 in qemu_thread_start util/qemu-thread-posix.c:502
9 0xffffa544e8bb in start_thread (/lib64/libpthread.so.0+0x78bb)
10 0xffffa53965cb in thread_start (/lib64/libc.so.6+0xd55cb)
This is because the opaque allocated in 'deflateInit2' is not freed in
'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
and in the latter will check whether 's->strm != strm'(libz's data structure).
This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',
so when calling 'deflateInit2', the 's->strm' will be the local address.
So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will
work as expection. The 'tight' of 'VncState' has the same issue, let's also turn
it to a pointer.

This allows to receive mouse and keyboard events from
a Barrier server.
This is enabled by adding the following parameter on the
command line
... -object input-barrier,id=$id,name=$name ...
Where $name is the name declared in the screens section of barrier.conf
The barrier server (barriers) must be configured and must run on the
local host.
For instance:
section: screens
localhost:
...
VM-1:
...
end
section: links
localhost:
right = VM-1
VM-1:
left = localhost
end
Then on the QEMU command line:
... -object input-barrier,id=barrie0,name=VM-1 ...
When the mouse will move out of the screen of the local host on
the right, the mouse and the keyboard will be grabbed and all
related events will be send to the guest OS.
This is usefull when qemu is configured without emulated graphic card
but with a VFIO attached graphic card.
More information about Barrier can be found at:
https://github.com/debauchee/barrier
This avoids to install the Barrier server in the guest OS,
for instance when it is not supported or during the installation.

and dependencies down."
Commit 4815185902 "trace: Add per-vCPU tracing states for events with

Ouch.
Per-vCPU tracing is currently not supported in sub-directories'
trace-events. In other words, qom/cpu.h can only be used in

Split trace/control-vcpu.h off trace/control.h and

Linux terminal behavior (coming from vt100 I think) is somewhat strange
when it comes to line wraps: When a character is printed to the last
char cell of a line the cursor does NOT jump to the next line but stays
where it is. The line feed happens when the next character is printed.
So the valid range for the cursor position is not 0 .. width-1 but
0 .. width, where x == width represents the state where the line is
full but the cursor didn't jump to the next line yet.
The code for the 'clear from start of line' control sequence (ESC[1K)
fails to handle this corner case correctly and may call
console_clear_xy() with x == width. That will incorrectly clear the
first char cell of the next line, or in case the cursor happens to be on
the last line overflow the cell buffer by one character (three bytes).
Add a check to the loop to fix that.
Didn't spot any other places with the same problem. But it's easy to
miss that corner case, so also allocate one extra cell as precaution, so
in case we have simliar issues lurking elsewhere it at least wouldn't be
a buffer overflow.

On Mojave, absolute input device, i.e. tablet, had trouble re-grabbing
the cursor in re-entry into the virtual screen area. In some cases,
the `window` property of NSEvent object was nil after cursor exiting from
window, hinting that the `-locationInWindow` method would return value in
screen coordinates. The current implementation used raw locations from
NSEvent without considering whether the value was for the window coordinates
or the macOS screen coordinates, nor the zooming factor for Zoom-to-Fit in
fullscreen mode.
In fullscreen mode, the fullscreen cocoa window might not be the key
window, therefore the location of event in virtual coordinates should
suffice.
This patches fixed boundary check methods for cursor in normal
and fullscreen with/without Zoom-to-Fit in Mojave.
Note: CGRect, -convertRectToScreen: and -convertRectFromScreen: were
used in coordinates conversion for compatibility reason.

The VNC server has historically had support for ACLs to check both the
SASL username and the TLS x509 distinguished name. The VNC server was
responsible for creating the initial ACL, and the client app was then
responsible for populating it with rules using the HMP 'acl_add' command.
This is not satisfactory for a variety of reasons. There is no way to
populate the ACLs from the command line, users are forced to use the
HMP. With multiple network services all supporting TLS and ACLs now, it
is desirable to be able to define a single ACL that is referenced by all
services.
To address these limitations, two new options are added to the VNC
server CLI. The 'tls-authz' option takes the ID of a QAuthZ object to
use for checking TLS x509 distinguished names, and the 'sasl-authz'
option takes the ID of another object to use for checking SASL usernames.
In this example, we setup two authorization rules. The first allows any
client with a certificate issued by the 'RedHat' organization in the
'London' locality. The second ACL allows clients with either the
'joe@REDHAT.COM' or 'fred@REDHAT.COM' kerberos usernames. Both checks
must pass for the user to be allowed.

That can cause vnc update stalls in case an unfinished vnc job gets

Fix that by copying the state from job_update back to update in that
case.
Reports complain about stalls with two or more clients being connected
at the same time, on some but not all connections. I suspect it can
also happen with a single connection, multiple connections only make
this more much likely to happen.

This makes use of wide curses functions instead of 8bit functions. This
allows to type e.g. accented letters.
Unfortunately, key codes are then returned with values that could be
confused with wide characters by ncurses, so we need to add a maybe_keycode
variable to know whether the returned value is a key code or a character
(curses with wide support), or possibly both (curses without wide support).
The translation tables thus also need to be separated into key code
translation and character translation. The curses2foo helper makes it easier
to use them.

The OSX Mojave release is more picky about enforcing the Cocoa API
restriction that only the main thread may perform UI calls. To
accommodate this we need to restructure the Cocoa code:
* the special OSX main() creates a second thread and uses
that to call the vl.c qemu_main(); the original main
thread goes into the OSX event loop
* the refresh, switch and update callbacks asynchronously
tell the main thread to do the necessary work
* the refresh callback no longer does the "get events from the
UI event queue and handle them" loop, since we now use
the stock OSX event loop. Instead our NSApplication sendEvent
method will either deal with them or pass them on to OSX
All these things have to be changed in one commit, to avoid
breaking bisection.
Note that since we use dispatch_get_main_queue(), this bumps
our minimum version requirement to OSX 10.10 Yosemite (released
in 2014, unsupported by Apple since 2017).

The 'qemu_acl' type was a previous non-QOM based attempt to provide an

created via the command line and requires special monitor commands to

The new QAuthZ subclasses provide a superset of the functionality in
qemu_acl, so the latter can now be deleted. The HMP 'acl_*' monitor
commands are converted to use the new QAuthZSimple data type instead

Add a new display backend that will configure Spice to allow a remote
client to control QEMU in a similar fashion as other QEMU display
backend/UI like GTK.
For this to work, it will set up Spice server with a unix socket, and
register a VC chardev that will be exposed as Spice ports. A QMP
monitor is also exposed as a Spice port, this allows the remote client
fuller qemu control and state handling.
- doesn't handle VC set_echo() - this doesn't seem a strong
requirement, very few front-end use it
- spice options can be tweaked with other -spice arguments

spice_server_vm_start/stop() was added to help migration state (commit
f5bb039c6d).
However, a paused VM could keep running the spice server. This will
allow a Spice client to keep sending commands to a spice chardev. This
allows to stop/cont a VM from a Spice monitor port. Character
devices (vdagent/usb/smartcard/..) should not read from Spice when the
VM is paused.

Passing several -spice options to qemu command line, or calling
several time qemu_opts_set() will ignore all but the first option
list. Since the spice server is a singleton, it makes sense to merge
all the options, the last value being the one taken into account.
This changes the behaviour from, for ex:
$ qemu... -spice port=5900 -spice port=5901 -> port: 5900
to:
$ qemu... -spice port=5900 -spice port=5901 -> port: 5901
(if necessary we could instead produce an error when an option is
given twice, although this makes handling default values and such more
complicated)

The Spice server doesn't like to be started or stopped twice . It
aborts with:
(process:6191): Spice-ERROR **: 19:29:35.912: red-worker.c:623:handle_dev_start: assertion `!worker->running' failed
It's easy to avoid that situation since qemu spice_display_is_running
tracks the server state.
After the commit "spice: do not stop spice if VM is paused", it will
be possible to pause and resume the VM, and this will call
qemu_spice_display_start() twice. The easiest is to add a check for
spice_display_is_running with this patch to avoid the assert.

The license information in this file is very messy. A short note at
the beginning says GPL first, but the long boilerplate code then
talks about "GNU Lesser General Public License version 2.0". First,
there is no such version of the "GNU Lesser GPL", it only started with
version 2.1. In version 2.0, it was still called "GNU Library GPL"
instead. Second, you can easily get the license of this file wrong
if you only quickly glance at the long boilerplate code.
Anyway, looking at the text of the LGPL (see COPYING.LIB in the top
directory), the license clearly states in section "3." that one should
rather replace the license information with the GPL information in
such a case of a mixture instead. Thus let's clean up the confusing
statements and use the proper GPL text only.

It is possible that the modifier state on keyup is different from the
modifier state on keydown. In that case the keycode lookup can end up
with different keys in case multiple keysym -> keycode mappings exist,
because it picks the mapping depending on modifier state.
To fix that change the lookup logic for keyup events. Instead of
looking at the modifier state check the key state and prefer a keycodes
where the key is in "down" state right now.

This patch adds helper code to track the state of all keyboard keys,
using a bitmap indexed by QKeyCode. Modifier state is tracked too,
as separate bitmap. That makes checking modifier state easier.
Likewise we can easily apply special handling for capslock & numlock

That will soon be 4 + 1/2 years ago, which is enough time to consider
the 2.0 series widely supported.

This patch adds a new option to the input-linux object:
grab-toggle=[key-combo]
The key combination can be one of the following:
* ctrl-ctrl
* alt-alt
* meta-meta
* scrolllock
* ctrl-scrolllock
The user can pick any of these key combinations. The VM's grab
of the evdev device will be toggled when the key combination is
pressed.
Any invalid setting will result in an error. No setting will
result in the current default of ctrl-ctrl.
The right and left ctrl key both work for Ctrl-Scrolllock.
If scrolllock is selected as one of the grab-toggle keys, it
will be entirely disabled and not passed to the guest at all.
This is to prevent enabling it while attempting to leave or enter
the VM. On the host, scrolllock can be disabled using xmodmap.
First, find the modifier that Scroll_Lock is bound to:
$ xmodmap -pm
Then, remove Scroll_Lock from it, replacing modX with the modifier:
$ xmodmap -e 'remove modX = Scroll_Lock'
If Scroll_Lock is not bound to any modifier, it is already disabled.
To save the changes, add them to your xinitrc.

Modern desktop environments can render icons at very large sizes,
especially with high DPI screens. Providing a 32x32 pixel bitmap is
nowhere near sufficient anymore.
When displayed in GNOME shell the QEMU icon looks awful, having been
scaled up to at least x4 its base size. This is compounded by the fact
that the BMP file doesn't do transparency, so while we've removed white
pixels, we still have anti-aliased nearly-white pixels which make the
logo look appalling on black backgrounds.
Loading a high resolution PNG icon addresses both problems, but requires
use of the extra SDL2_image library.

directory location.
Pre-rendered icons are provided at the standard sizes expected for GUI
applications, along with the scalable SVG, to ensure maximum portability.
The PNGs are rendered from the SVG using inkscape, however, this is not
wired up into the default make rules to avoid requiring inkscape as a

the change will also remove the need to name heads when doing backwards

Note that a previous version of this patch was bumping version to
0.12.6. Unfortunately, Debian Jessie (oldstable) is stuck with spice
server 0.12.5, and QEMU should keep building until after 2y of current
stable (Stretch), which will be around June 17th 2019. Qemu 4.1
should thus be free of bumping to spice-server 0.12.6 during 4.1
development cycle.

Future spice-server versions will call the client_monitors_config
callback with the monitors list filtered to only include the monitors
of the given display channel (aka QXLInstance). Luckily this is easily
detectable at runtime, so we can prepare for that in advance and also
make qemu compatible with both old and new spice-server versions.
While being at it also use the console index instead of head number as
array index. The later doesn't work correctly in case multiple display
devices are present.

That patch series introduced new virtual clock type for use in external
subsystems. It breaks desired behavior in non-record/replay usage
scenarios due to a small change to existing behavior. Processing of
virtual timers belonging to new clock type is kicked off to the main
loop, which makes these timers asynchronous with vCPU thread and,
in icount mode, with whole guest execution. This breaks expected
determinism in non-record/replay icount mode of emulation where these
"external subsystems" are isolated from the host (i.e. they are
external only to guest core, not to the entire emulation environment).
Example for slirp ("user" backend for network device):
User runs qemu in icount mode with rtc clock=vm without any external
communication interfaces but with "-netdev user,restrict=on". It expects
deterministic execution, because network services are emulated inside
qemu and isolated from host. There are no reasons to get reply from DHCP
server with different delay or something like that.
The next patches revert reimplements the same changes in a better way.

The GTK 3.0 release was made in Feb, 2011:
https://blog.gtk.org/2011/02/10/gtk-3-0-released/
That will soon be 7 years ago, which is enough time to consider
the 3.x series widely supported.
Thus we deprecate the GTK 2.x support, which will allow us to
delete it in the last release of 2018. By this time, GTK 3.x
will be almost 8 years old.

UI uses timers based on virtual clock for managing key queue.
This is incorrect because this service is not related to the guest state,
and its events should not be recorded and replayed. But these timers should
stop when the guest is not executing.

which runs as virtual clock, but its timers are not saved to the log.

VNC server is calling sasl_server_init() during startup of QEMU, even
if SASL auth has not been enabled.
This may create undesirable warnings like "Could not find keytab file:

started VNC server.
Instead, only initialize SASL when needed. Note that HMP/QMP "change

needed.

Monochrome cursors are still used by Windows guests with the
QXL-WDDM-DOD driver. Such cursor types have one odd feature, inversion
of colors. GDK does not seem to support it, so implement an alternative
solution: fill the inverted pixels and add an outline to make the cursor
more visible. Tested with the text cursor in Notepad and Windows 10.
cursor_set_mono is also used by the vmware GPU, so add a special check
to avoid breaking its 32bpp format (tested with Kubuntu 14.04.4). I was
unable to find a guest which supports the 1bpp format with a vmware GPU.
The old implementation was buggy and removed in v2.10.0-108-g79c5a10cdd
("qxl: drop mono cursor support"), this version improves upon that by
adding bounds validation, clarifying the semantics of the two masks and
adds a workaround for inverted colors support.

spice-display should not call the ui/console.c functions dpy_cursor_define
and dpy_moues_set with the SimpleSpiceDisplay lock taken. That will cause
a deadlock, because the DisplayChangeListener callbacks will take the lock
again. It is also in general a bad idea to invoke generic callbacks with a
lock taken, because it can cause AB-BA deadlocks in the long run. The only
thing that requires care is that the cursor may disappear as soon as the
mutex is released, so you need an extra cursor_get/cursor_put pair.

The NSEvent class method scrollingDeltaY is available
for Mac OS 10.7 and newer. Since QEMU supports Mac OS
10.5 and up, we need to be using a method that is
available on these version of Mac OS X. The deltaY
method is a method that does almost the same thing as
scrollingDeltaY and is available on Mac OS 10.5 and
up. So we can replace scrollingDeltaY with deltaY.
We only check deltaY's value if it is not zero
because zero means that the scrolling increment was
sufficiently fine that it was only reported in scrollingDeltaY,
or that the scrolling was horizontal.

Add #if defined(CONFIG_VNC) in generated code, and adjust the
qmp/hmp code accordingly.
query-qmp-schema no longer reports the command/events etc as
available when disabled at compile.
Commands made conditional:
* query-vnc, query-vnc-servers, change-vnc-password
Before the patch, the commands for !CONFIG_VNC are stubs that fail
like this:
{"error": {"class": "GenericError",
"desc": "The feature 'vnc' is not enabled"}}
Afterwards, they fail like this:
{"error": {"class": "CommandNotFound",
"desc": "The command FOO has not been found"}}
I call that an improvement, because it lets clients distinguish
between command unavailable (class CommandNotFound) and command failed
(class GenericError).
Events made conditional:
* VNC_CONNECTED, VNC_INITIALIZED, VNC_DISCONNECTED
HMP change:
* info vnc
Will return "unknown command: 'info vnc'" when VNC is compiled
out (same as error for spice when --disable-spice)
Occurrences of VNC (case insensitive) in the schema that aren't
covered by this change:
* add_client
Command has other uses, including "socket bases character devices".
These are unconditional as far as I can tell.
* set_password, expire_password
In theory, these commands could be used for managing any service's
password. In practice, they're used for VNC and SPICE services.
They're documented for "remote display session" / "remote display
server".
The service is selected by argument @protocol. The code special-cases
protocol-specific argument checking, then calls a protocol-specific
function to do the work. If it fails, the command fails with "Could
not set password". It does when the service isn't compiled in (it's a
stub then).
We could make these commands conditional on the conjunction of all
services [currently: defined(CONFIG_VNC) || defined(CONFIG_SPICE)],
but I doubt it's worthwhile.
* change
Command has other uses, namely changing media.
This patch inlines a stub; no functional change.

A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().
add_link() doesn't add a reference to the target object, while
set_link() does.
Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.
Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG

The X11 code currently detects the keymap by looking for the keycode
name property. Unfortunately due to the way Xwayland handles keyboards,
this property gets unset almost immediately after the first application
starts using Xwayland resulting in
** (qemu-system-x86_64:19644): WARNING **: Unknown X11 keycode mapping '(unnamed)'.
Please report to qemu-devel@nongnu.org
including the following information:
- Operating system
- X11 Server
- xprop -root
- xdpyinfo
Fortunately people will only see this problem if they built QEMU with
GTK2, or have told GTK3 to prefer X11 by setting the GDK_BACKEND=x11
env variable.
To workaround the problem, we add a heuristic that looks at what
scancode the XK_Page_Up keysymbol maps to, to determine if we've
likely got the X11 kbd or evdev driver.

This patch allows to unbind devices from QemuConsoles, using the new
graphic_console_close() function. The QemuConsole will show a static
display then, saying the device was unplugged. When re-plugging a
display later on the QemuConsole will be reused.
Eventually we will allocate and release QemuConsoles dynamically at some
point in the future, that'll need more infrastructure though to notify

Since commit 67a1de0d19 there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :
$ qemu-system-s390x --version
QEMU emulator version 2.11.50(foo)
But the space is included when building without that option
when building from a git checkout:
$ qemu-system-s390x --version
QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)
The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

QEMU's screendump command can only take dumps from the primary display.
When using multiple VGA cards, there is no way to get a dump from a
secondary card or other display heads yet. So let's add a 'device' and
a 'head' parameter to the HMP and QMP commands to be able to specify
alternative devices and heads with the screendump command, too.

Secondary displays in multihead setups are allowed to have a NULL
DisplaySurface. Typically user interfaces handle this by hiding the
window which shows the display in question.
This isn't an option for vnc though because it simply hasn't a concept
of windows or outputs. So handle the situation by showing a placeholder
DisplaySurface instead. Also check in console_select whenever a surface
is preset in the first place before requesting an update.
This fixes a segfault which can be triggered by switching to an unused
display (via vtrl-alt-<nr>) in a multihead setup, for example using
-device virtio-vga,max_outputs=2.

The previous commit improved compile time by including less of the

in qapi-schema.json, because that ends up in headers that that pull in
everything.
Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.
It's possible everywhere, except:
* monitor.c needs qmp-command.h to get qmp_init_marshal()
* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
qapi-event.h to get enum QAPIEvent

For very large framebuffers, it is theoretically possible for the result
of 'vs->throttle_output_offset * VNC_THROTTLE_OUTPUT_LIMIT_SCALE' to
exceed the size of a 32-bit int. For this to happen in practice, the
video RAM would have to be set to a large enough value, which is not
likely today. None the less we can be paranoid against future growth by
using division instead of multiplication when checking the limits.

Having analyzed the coredump, I understood that the reason is that
ioc_tag is reset on vnc_disconnect_start and ioc is cleaned
in vnc_disconnect_finish. Between these two events due to some
reasons the ioc_tag was set again and after vnc_disconnect_finish
the handler is running with freed ioc,
which led to the segmentation fault.
The patch checks vs->disconnecting in places where we call
qio_channel_add_watch and resets handler if disconnecting == TRUE
to prevent such an occurrence.

ui: track how much decoded data we consumed when doing SASL encoding
I attempted to fix a flaw with tracking how much data had actually been
processed when encoding with SASL. With that flaw, the VNC server could
mistakenly discard queued data that had not been sent.
The fix was not quite right though, because it merely decremented the
vs->output.offset value. This is effectively discarding data from the
end of the pending output buffer. We actually need to discard data from
the start of the pending output buffer. We also want to free memory that
is no longer required. The correct way to handle this is to use the
buffer_advance() helper method instead of directly manipulating the
offset value.

changed the x_keymap.c keymap so that its target was qcodes instead of

forgot to update the SDL1 frontend. Thus the SDL frontend was getting
qcodes but dispatching them as if they were qnums. IOW, keyboard input
was completely hosed with SDL1. Since the keyboard layout tables are
still all based on qnums, it is easier to just keep SDL1 using qnums as
it will be deleted in a few releases time.

The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'. Although our coding style frowns on brace-less 'if':
if (cond)
statement;
else
something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'. But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'. Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.
The change should have no semantic impact. I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.

When SDL2 windows change focus while a key is held, the window that
receives the focus also receives a new KeyDown event, without an
autorepeat flag. This means that if a WM places the qemu console
over the main window after Ctrl-Alt-2, the console closes immediately
after opening. Then, the main window receives the KeyDown event again
and the whole process repeats.
This patch makes the SDL2 UI ignore the KeyDown events on a window that
just received the focus, if the GUI modifier was held. The ignore flag
is reset on a first KeyUp event. This effectively works around the issue
above.

The previous patches fix problems with throttling of forced framebuffer updates
and audio data capture that would cause the QEMU output buffer size to grow
without bound. Those fixes are graceful in that once the client catches up with
reading data from the server, everything continues operating normally.
There is some data which the server sends to the client that is impractical to
throttle. Specifically there are various pseudo framebuffer update encodings to
inform the client of things like desktop resizes, pointer changes, audio
playback start/stop, LED state and so on. These generally only involve sending
a very small amount of data to the client, but a malicious guest might be able
to do things that trigger these changes at a very high rate. Throttling them is
not practical as missed or delayed events would cause broken behaviour for the
client.
This patch thus takes a more forceful approach of setting an absolute upper
bound on the amount of data we permit to be present in the output buffer at
any time. The previous patch set a threshold for throttling the output buffer
by allowing an amount of data equivalent to one complete framebuffer update and
one seconds worth of audio data. On top of this it allowed for one further
forced framebuffer update to be queued.
To be conservative, we thus take that throttling threshold and multiply it by
5 to form an absolute upper bound. If this bound is hit during vnc_write() we
forceably disconnect the client, refusing to queue further data. This limit is
high enough that it should never be hit unless a malicious client is trying to
exploit the sever, or the network is completely saturated preventing any sending
of data on the socket.
This completes the fix for CVE-2017-15124 started in the previous patches.

The VNC server must throttle data sent to the client to prevent the 'output'
buffer size growing without bound, if the client stops reading data off the
socket (either maliciously or due to stalled/slow network connection).
The current throttling is very crude because it simply checks whether the
output buffer offset is zero. This check is disabled if the client has requested
a forced update, because we want to send these as soon as possible.
As a result, the VNC client can cause QEMU to allocate arbitrary amounts of RAM.
They can first start something in the guest that triggers lots of framebuffer
updates eg play a youtube video. Then repeatedly send full framebuffer update
requests, but never read data back from the server. This can easily make QEMU's
VNC server send buffer consume 100MB of RAM per second, until the OOM killer
starts reaping processes (hopefully the rogue QEMU process, but it might pick
others...).
To address this we make the throttling more intelligent, so we can throttle
full updates. When we get a forced update request, we keep track of exactly how
much data we put on the output buffer. We will not process a subsequent forced
update request until this data has been fully sent on the wire. We always allow
one forced update request to be in flight, regardless of what data is queued
for incremental updates or audio data. The slight complication is that we do
not initially know how much data an update will send, as this is done in the
background by the VNC job thread. So we must track the fact that the job thread
has an update pending, and not process any further updates until this job is
has been completed & put data on the output buffer.
This unbounded memory growth affects all VNC server configurations supported by
QEMU, with no workaround possible. The mitigating factor is that it can only be
triggered by a client that has authenticated with the VNC server, and who is
able to trigger a large quantity of framebuffer updates or audio samples from
the guest OS. Mostly they'll just succeed in getting the OOM killer to kill
their own QEMU process, but its possible other processes can get taken out as
collateral damage.
This is a more general variant of the similar unbounded memory usage flaw in
the websockets server, that was previously assigned CVE-2017-15268, and fixed
in 2.11 by:

socket (either maliciously or due to stalled/slow network connection).
The current throttling is very crude because it simply checks whether the
output buffer offset is zero. This check must be disabled if audio capture is
enabled, because when streaming audio the output buffer offset will rarely be
zero due to queued audio data, and so this would starve framebuffer updates.

processes (hopefully the rogue QEMU process, but it might pick others...).
To address this we make the throttling more intelligent, so we can throttle
when audio capture is active too. To determine how to throttle incremental
updates or audio data, we calculate a size threshold. Normally the threshold is
the approximate number of bytes associated with a single complete framebuffer
update. ie width * height * bytes per pixel. We'll send incremental updates
until we hit this threshold, at which point we'll stop sending updates until
data has been written to the wire, causing the output buffer offset to fall
back below the threshold.
If audio capture is enabled, we increase the size of the threshold to also
allow for upto 1 seconds worth of audio data samples. ie nchannels * bytes
per sample * frequency. This allows the output buffer to have a mixture of
incremental framebuffer updates and audio data queued, but once the threshold
is exceeded, audio data will be dropped and incremental updates will be
throttled.

According to the RFB protocol, a client sends one or more framebuffer update
requests to the server. The server can reply with a single framebuffer update
response, that covers all previously received requests. Once the client has
read this update from the server, it may send further framebuffer update
requests to monitor future changes. The client is free to delay sending the
framebuffer update request if it needs to throttle the amount of data it is
reading from the server.
The QEMU VNC server, however, has never correctly handled the framebuffer
update requests. Once QEMU has received an update request, it will continue to
send client updates forever, even if the client hasn't asked for further
updates. This prevents the client from throttling back data it gets from the
server. This change fixes the flawed logic such that after a set of updates are
sent out, QEMU waits for a further update request before sending more data.

When we encode data for writing with SASL, we encode the entire pending output
buffer. The subsequent write, however, may not be able to send the full encoded
data in one go though, particularly with a slow network. So we delay setting the
output buffer offset back to zero until all the SASL encoded data is sent.
Between encoding the data and completing sending of the SASL encoded data,
however, more data might have been placed on the pending output buffer. So it
is not valid to set offset back to zero. Instead we must keep track of how much
data we consumed during encoding and subtract only that amount.
With the current bug we would be throwing away some pending data without having
sent it at all. By sheer luck this did not previously cause any serious problem
because appending data to the send buffer is always an atomic action, so we
only ever throw away complete RFB protocol messages. In the case of frame buffer
updates we'd catch up fairly quickly, so no obvious problem was visible.

The 'sysrq' key was mistakenly added to QEMU to deal with incorrect handling
of the 'print' key in the ps2 device:
commit f2289cb692

Add sysrq to key names known by "sendkey".
Adding sysrq keycode to the table enabling running sysrq debugging in

The ps2 device is now fixed wrt modifiers and the 'print' key. Further the
handling of the 'sysrq' key has some problems of its own, documented in the
previous commit. To cleanup this mess, we convert any use of 'sysrq' into
'print' prior to dispatching the event to device models.

The code converting key numbers to QKeyCode in the 'input-send-event'
command mistakenly accessed the key->u.qcode union field instead of
the key->u.number field. This is harmless because the fields use the
same size datatype in both cases, but none the less it should be fixed
to avoid confusion.

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)

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.

Indentation fixed up manually afterwards.
Some of the lines were manually edited to reduce the line length to below
80 charecters. Some of the lines with newlines in the middle of the
string were also manually edit to avoid checkpatch errrors.
The #include lines were manually updated to allow the code to compile.
