Convert all the multi-line uses of fprintf(stderr, "warning:"..."\n"...
to use warn_report() instead. This helps standardise on a single
method of printing warnings to the user.
All of the warnings were changed using these commands:
find ./* -type f -exec sed -i \
'N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
{} +
find ./* -type f -exec sed -i \

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.

Author: Hervé Poussineau <hpoussin@reactos.org>
Date: Thu Sep 15 22:06:26 2016 +0200
ps2: use QEMU qcodes instead of scancodes
When using a VNC client, with the raw scancode extension, the client
will send a scancode of 0xc6 for both PAUSE and BREAK. There is mistakenly
no entry in the qcode_to_number table for this scancode, so
ps2_keyboard_event() just generates a log message and discards the
scancode
When using a SPICE client, it will also send 0xc6 for BREAK, but
will send 0xe1 0x1d 0x45 0xe1 0x9d 0xc5 for PAUSE. There is no
entry in the qcode_to_number table for the scancode 0xe1 because
it is a special XT keyboard prefix not mapping to any QKeyCode.
Again ps2_keyboard_event() just generates a log message and discards
the scancode. The following 0x1d, 0x45, 0x9d, 0xc5 scancodes get
handled correctly. Rather than trying to handle 3 byte sequences
of scancodes in the PS/2 driver, special case the SPICE input
code so that it captures the 3 byte pause sequence and turns it
into a Pause QKeyCode.

The current VNC default keyboard delay is 1ms. With that we're constantly
typing faster than the guest receives keyboard events from an XHCI attached
USB HID device.
The default keyboard delay time in the input layer however is 10ms. I don't know
how that number came to be, but empirical tests on some OpenQA driven ARM
systems show that 10ms really is a reasonable default number for the delay.
This patch moves the VNC delay also to 10ms. That way our default is much
safer (good!) and also consistent with the input layer default (also good!).

I had two problems with QEMU on macOS:
1) Sometimes when alt-tabbing to QEMU it would act as if the 'a' key
was pressed so I'd get 'aaaaaaaaa....'.
2) Using Sikuli to programatically send keys to the QEMU window text
like "foo_bar" would come out as "fooa-bar".
They looked similar and after much digging the problem turned out to be
the same. When QEMU's ui/cocoa.m received an NSFlagsChanged NSEvent it
looked at the keyCode to determine what modifier key changed. This
usually works fine but sometimes the keyCode is 0 and the app should
instead be looking at the modifierFlags bitmask. Key code 0 is the 'a'
key.
I added code that handles keyCode == 0 differently. It checks the
modifierFlags and if they differ from QEMU's idea of which modifier
keys are currently pressed it toggles those changed keys.
This fixes my problems and seems work fine.

Time to wire up all the call sites that request a shutdown or
reset to use the enum added in the previous patch.
It would have been less churn to keep the common case with no
arguments as meaning guest-triggered, and only modified the
host-triggered code paths, via a wrapper function, but then we'd
still have to audit that I didn't miss any host-triggered spots;
changing the signature forces us to double-check that I correctly
categorized all callers.
Since command line options can change whether a guest reset request
causes an actual reset vs. a shutdown, it's easy to also add the
information to reset requests.

This patch adds support for absolute pointer events to the input-linux
subsystem. This support was omitted from the original input-linux patch,
however most of the code required for it is already in place.
Support for absolute events is especially useful for guests with vga
passthrough. Since they have a physical monitor, none of normal channels
for sending video output (vnc, etc) are used, meaning they also can't be
used to send absolute input events. This leaves QMP as the only option
to send absolute input into vga passthrough guests, which is not its
intended use and is not efficient.
This patch allows, for example, uinput to be used to create virtual
absolute input devices. This lets you build external systems which share
physical input devices between guests. Without absolute input
capability, such external systems can't seamlessly share pointer devices
between guests.

qemu_input_event_send() discards key event when the guest is paused,

The delay ends up in the input queue, and qemu_input_event_send_key()
will further fill the queue with upcoming events.
VNC uses qemu_input_event_send_key_delay(), not SPICE, which results
in a different input behaviour on pause: VNC will queue the events
(except the first that is discarded), SPICE will discard all events.
Don't queue delay if paused, and provide same behaviour on SPICE and
VNC clients on resume (and potentially avoid over-allocating the

tcg: drop global lock during TCG code execution
..broke the assumption that updates to the GUI couldn't happen at the
same time as TCG vCPUs where running. As a result the TCG vCPU could
still be updating a directly mapped frame-buffer while the display
side was updating. This would cause artefacts to appear when the
update code assumed that memory block hadn't changed.
The simplest solution is to ensure the two things can't happen at the
same time like the old BQL locking scheme. Here we use the solution
introduced for MTTCG and schedule the update as async_safe_work when
we know no vCPUs can be running.

Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
There is a special code path (dpy_gfx_copy) to allow graphic emulation
notify user interface code about bitblit operations carryed out by
guests. It is supported by cirrus and vnc server. The intended purpose
is to optimize display scrolls and just send over the scroll op instead
of a full display update.
This is rarely used these days though because modern guests simply don't
use the cirrus blitter any more. Any linux guest using the cirrus drm
driver doesn't. Any windows guest newer than winxp doesn't ship with a
cirrus driver any more and thus uses the cirrus as simple framebuffer.
So this code tends to bitrot and bugs can go unnoticed for a long time.
See for example commit "3e10c3e vnc: fix qemu crash because of SIGSEGV"
which fixes a bug lingering in the code for almost a year, added by
commit "c7628bf vnc: only alloc server surface with clients connected".
Also the vnc server will throttle the frame rate in case it figures the
network can't keep up (send buffers are full). This doesn't work with
dpy_gfx_copy, for any copy operation sent to the vnc client we have to
send all outstanding updates beforehand, otherwise the vnc client might
run the client side blit on outdated data and thereby corrupt the
display. So this dpy_gfx_copy "optimization" might even make things
worse on slow network links.
Lets kill it once for all.
Oh, and one more reason: Turns out (after writing the patch) we have a
security bug in that code path ...

just bearable if listening on wildcard interface, or if

but if there are multiple NICs and the VNC server needs
to listen on 2 or more specific IP addresses, it can't be

Currently the VNC authentication info is emitted at the
top level of the query-vnc-servers data. This is wrong
because the authentication scheme differs between plain

report auth against the individual servers. e.g.
(QEMU) query-vnc-servers
{
"return": [
{
"clients": [],

When qemu vnc server is trying to send large update to clients,
there might be a situation when system responds with something
like EAGAIN, indicating that there's no system memory to send
that much data (depending on the network speed, client and server
and what is happening). In this case, something like this happens
on qemu side (from strace):
sendmsg(16, {msg_name(0)=NULL,
msg_iov(1)=[{"\244\"..., 729186}],
msg_controllen=0, msg_flags=0}, 0) = 103950
sendmsg(16, {msg_name(0)=NULL,
msg_iov(1)=[{"lz\346"..., 1559618}],
msg_controllen=0, msg_flags=0}, 0) = -1 EAGAIN
sendmsg(-1, {msg_name(0)=NULL,
msg_iov(1)=[{"lz\346"..., 1559618}],
msg_controllen=0, msg_flags=0}, 0) = -1 EBADF
qemu closes the socket before the retry, and obviously it gets EBADF
when trying to send to -1.
This is because there WAS a special handling for EAGAIN, but now it doesn't
work anymore, after commit 04d2529da2, because
now in all error-like cases we initiate vnc disconnect.
This change were introduced in qemu 2.6, and caused numerous grief for many
people, resulting in their vnc clients reporting sporadic random disconnects
from vnc server.
Fix that by doing the disconnect only when necessary, i.e. omitting this
very case of EAGAIN.
Hopefully the existing condition (comparing with QIO_CHANNEL_ERR_BLOCK)
is sufficient, as the original code (before the above commit) were
checking for other errno values too.
Apparently there's another (semi?)bug exist somewhere here, since the
code tries to write to fd# -1, it probably should check if the connection
is open before. But this isn't important.

Commit 2cb5d2a4 removed setlocale() for everything except LC_MESSAGES in
order to avoid unwanted side effects such as using the wrong decimal
separator in generated JSON objects. However, the problem that unsetting
LC_CTYPE caused is that non-ASCII characters are considered
non-printable now and therefore the GTK menus display question marks for
accented letters, Chinese characters etc.
A first attempt to fix this [1] was rejected because even just setting
LC_CTYPE to the user's locale (and thereby modifying the semantics of
the ctype.h functions) could have unwanted effects that we're not aware
of yet.
Recently, however, glibc introduced a new locale "C.utf-8" that just
uses UTF-8 as its charset, but otherwise leaves the semantics alone.
Just setting the right character set is enough for our use case, so we
can just hardcode this one without having to be afraid of nasty side
effects.
Older systems that don't have the new locale will continue displaying
question marks, but this should fix the problem for most users.

The class kind is necessary to lookup the chardev name in
qmp_chardev_add() after calling qemu_chr_new_from_opts() and to set
the appropriate ChardevBackend (mainly to free the right
fields).
qemu_chr_new_from_opts() can be changed to use a non-qmp function
using the chardev class typename. Introduce qemu_chardev_add() to be
called from qemu_chr_new_from_opts() and remove the class chardev kind
field. Set the backend->type in the parse callback (when non-common
fields are added).

qemu_chr_new_from_opts() is modified to not need CharDriver backend[]
array, but uses instead objectified qmp_query_chardev_backends() and
char_get_class(). The alias field is moved outside in a ChardevAlias[],
similar to QDevAlias for devices.
"kind" and "parse" are moved to ChardevClass ("kind" is to be removed

Turn Chardev into Object.
qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It
will call qemu_char_open() to open/intialize the chardev with the
ChardevCommon *backend settings.
The CharDriver::create() callback is turned into a ChardevClass::open()
which is called from the newly introduced qemu_chardev_open().
"chardev-gdb" and "chardev-hci" are internal chardev and aren't
creatable directly with -chardev. Use a new internal flag to disable
them. We may want to use TYPE_USER_CREATABLE interface instead, or
perhaps allow -chardev usage.
Although in general we keep typename and macros private, unless the type
is being used by some other file, in this patch, all types and common
helper macros for qemu-char.c are in char.h. This is to help transition
now (some types must be declared early, while some aren't shared) and
when splitting in several units. This is to be improved later.

Use a single allocation for CharDriverState, this avoids extra
allocations & pointers, and is a step towards more object-oriented
CharDriver.
Gtk console is a bit peculiar, gd_vc_chr_set_echo() used to have a
temporary VirtualConsole to save the echo bit. Instead now, we consider
whether vcd->console is set or not, and restore the echo bit saved in
VCDriverState when calling gd_vc_vte_init().
The casts added are temporary, they are replaced with QOM type-safe
macros in a later patch in this series.

This results in lots of compiler warnings like this one:
CC vl.o

from /qemu/vl.c:76:
/usr/i686-w64-mingw32/sys-root/mingw/include/curses.h:1522:0: warning: "KEY_EVENT" redefined

#define KEY_EVENT 0x1
QEMU only uses the KEY_EVENT macro from wincon.h.
Therefore we can undefine the macro coming from curses.h.
The explicit include statement for curses.h in ui/curses.c is not needed
and was removed.
Those two modifications fix the redefinition warnings.

If the buffer is not big enough, snprintf() does not return the number
of bytes that have been written to the buffer, but the number of bytes
that would be needed for writing the whole string. By using this value
for the following vnc_write() calls, we send some junk at the end of
the name in case the qemu_name is longer than 1017 bytes, which could
confuse the VNC clients. Fix this by adding an additional size check

Since the hanlders are associated with a CharBackend, rather than the
CharDriverState, it is more appropriate to store in CharBackend. This
avoids the handler copy dance in qemu_chr_fe_set_handlers() then
mux_chr_update_read_handler(), by storing the CharBackend pointer
directly.
Also a mux CharDriver should go through mux->backends[focused], since
chr->be will stay NULL. Before that, it was possible to call
chr->handler by mistake with surprising results, for ex through
qemu_chr_be_can_write(), which would result in calling the last set
handler front end, not the one with focus.

Query input device keys, initialize state accordingly, so the correct
state is reflected in case any key is pressed at initialization time.
There is a high chance for this to actually happen for the 'enter' key
in case you start qemu with a terminal command (directly or virsh).
When finding any pressed keys the input grab is delayed until all keys
are lifted, to avoid confusing guest and host with appearently stuck

vnc_connect() method, but some are done in vnc_init_state()
instead.
The purpose of having vnc_init_state() is to delay starting
of the VNC wire protocol until after the websockets handshake
has completed. As such the vnc_init_state() method only needs
to be used for initialization that is dependant on the wire
protocol running.
This also lets us get rid of the initialized boolean flag
from the VncState struct.

The vnc_init_state method calls reset_keys() to reset the
modifier key state. This was originally added in

Reset the key modifiers upon client connect
This was valid at this time because there was only the
single VncState object which was persistent across client
connections and so needed resetting.
The persistent data was later split off into VncDisplay
and VncState was allocated at time of client connection:

Support multiple VNC clients (Brian Kress)
at which point the modifier state is always 0 due to
use of g_new0. As such the reset_keys() call has been
a no-op ever since.

Just before accepting a new client connection the vnc_listen_io
method calls graphic_hw_update(). This is bogus because there
is a call to this method already in vnc_state_init() and the
client doesn't need up2date graphics console before reaching
that.

There is a lot of repeated code in the auth type setup method,
particularly around checking TLS credential types. Refactor
it to reduce duplication and instead of having one method
do both plain and websockets at once, call it separately
for each.

Normally code declares 'VncDisplay *vd' or 'VncState *vs'
but there are a bunch of places which misleadingly declare
'VncDisplay *vs'.
