For any modifier key (shift, ctrl, alt) still pressed on disconnect
inject a key-up event into the guest. The vnc client is gone, it will
not do that, so qemu has to do it instead.
Without this keys will get stuck, making the guest act in weird ways
after reconnecting. Reproducer: exit vnc client via Alt-F4, guest
continues to see the pressed alt key and will not react to key events
in any useful way until you tap the alt key once to unstuck it.

VNC clients send a shared flag in the client init message. Up to now
qemu completely ignores this. This patch implements shared flag
handling. It comes with three policies: By default qemu behaves as one
would expect: Asking for a exclusive access grants exclusive access to
the client connecting. There is also a desktop sharing mode which
disallows exclusive connects (so one forgetting -shared wouldn't drop
everybody else) and a compatibility mode which mimics the traditional
(but non-conforming) qemu behavior.

vnc assumes that the screen width is a multiple of 16 in several places.
If this is not the case vnc will overrun buffers, corrupt memory, make
qemu crash.
This is the minimum fix for this bug. It makes sure we don't overrun the
scanline, thereby fixing the segfault. The rendering is *not* correct
though, there is a black border at the right side of the screen, 8
pixels wide because 1400 % 16 == 8.

There are scenarios on Linux with some SDL versions where
handle_activation is continuous invoked with state = SDL_APPINPUTFOCUS
and gain = 0 while we grabbed the input. This causes a ping-pong when we
grab the input after an absolute mouse entered the window.
As this sdl_grab_end was once introduced to work around a Windows-only

There are three important remarks in relation to the non-qapi command:
1. This commit also fixes the behavior of the 'query-vnc' and 'info vnc'
commands to return an error when qemu is built without VNC support
(ie. --disable-vnc). The non-qapi command would return the OK
response in QMP and no response in HMP
2. The qapi version explicitly marks the fields 'host', 'family',
'service' and 'auth' as optional. Their are not documented as optional
in the non-qapi command doc, but they would not be returned if
vnc support is disabled. The qapi version maintains the same
semantics, but documents those fields correctly
3. The 'clients' field, which is a list, is marked as optional but is
always returned. If there are no clients connected an empty list
is returned. This is not the Right Way to this in the qapi but it's
how the non-qapi command used to work

Today, when notifying a VM state change with vm_state_notify(),
we pass a VMSTOP macro as the 'reason' argument. This is not ideal
because the VMSTOP macros tell why qemu stopped and not exactly
what the current VM state is.
One example to demonstrate this problem is that vm_start() calls
vm_state_notify() with reason=0, which turns out to be VMSTOP_USER.

Allow client connections for VNC and socket based character
devices to be passed in over the monitor using SCM_RIGHTS.
One intended usage scenario is to start QEMU with VNC on a
UNIX domain socket. An unprivileged user which cannot access
the UNIX domain socket, can then connect to QEMU's VNC server
by passing an open FD to libvirt, which passes it onto QEMU.

{ "return": {} }
{ "execute": "add_client", "arguments": { "protocol": "vnc",
"fdname": "myclient",
"skipauth": true } }
{ "return": {} }
In this case 'protocol' can be 'vnc' or 'spice', or the name
of a character device (eg from -chardev id=XXXX)
The 'skipauth' parameter can be used to skip any configured
VNC authentication scheme, which is useful if the mgmt layer

in another way.

Turn on SASL support by appending "sasl" to the spice arguments, which
requires that the client use SASL to authenticate with the spice. The
exact choice of authentication method used is controlled from the
system / user's SASL configuration file for the 'qemu' service. This
is typically found in /etc/sasl2/qemu.conf. If running QEMU as an
unprivileged user, an environment variable SASL_CONF_PATH can be used
to make it search alternate locations for the service config. While
some SASL auth methods can also provide data encryption (eg GSSAPI),
it is recommended that SASL always be combined with the 'tls' and
'x509' settings to enable use of SSL and server certificates. This
ensures a data encryption preventing compromise of authentication
credentials.
It requires support from spice 0.8.1.

fix 2Gb integer overflow in in VNC tight and zlib encodings
As found by Roland Dreier <roland@purestorage.com> (excellent
catch!), when amount of VNC compressed data produced by zlib
and sent to client exceeds 2Gb, integer overflow occurs because
currently, we calculate amount of data produced at each step by
comparing saved total_out with new total_out, and total_out is
something which grows without bounds. Compare it with previous
avail_out instead of total_out, and leave total_out alone.
The same code is used in vnc-enc-tight.c and vnc-enc-zlib.c,
so fix both cases.
There, there's no actual need to save previous_out value, since
capacity-offset (which is how that value is calculated) stays
the same so it can be recalculated again after call to deflate(),
but whole thing becomes less readable this way.

after checking that get_clock and new_timer never occur twice
on the same line. There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

We have qemu_cpu_self and qemu_thread_self. The latter is retrieving the
current thread, the former is checking for equality (using CPUState). We
also have qemu_thread_equal which is only used like qemu_cpu_self.
This refactors the interfaces, creating qemu_cpu_is_self and
qemu_thread_is_self as well ass qemu_thread_get_self.

Commit bc2429b917 introduced
a severe bug (stack corruption).
bitmap_clear was called with a wrong argument
which caused out-of-bound writes to the local variable width_mask.
This bug was detected with QEMU running on windows.
It also occurs with wine:
*** stack smashing detected ***: terminated
wine: Unhandled illegal instruction at address 0x6115c7 (thread 0009), starting debugger...
The bug is not windows specific!
Instead of fixing the wrong parameter value, bitmap_clear(), bitmap_set
and width_mask were removed, and bitmap_intersect() was replaced by
!bitmap_empty(). The new operation is much shorter and equivalent to
the old operations.
The declarations of the dirty bitmaps in vnc.h were also wrong for 64 bit
hosts because of a rounding effect: for these hosts, VNC_MAX_WIDTH is no
longer a multiple of (16 * BITS_PER_LONG), so the rounded value of
VNC_DIRTY_WORDS was too small.
Fix both declarations by using the macro which is designed for this
purpose.

VncJobQueue's buffer is intended to be used for
as the output buffer for all operations in this queue,
but unfortunatly.
vnc_async_encoding_start() is in charge of setting this
buffer as the current output buffer, but
vnc_async_encoding_end() was not writting the changes back
to VncJobQueue, resulting in a big and ugly memleak.
