bc119048d7 vnc: Tweak error when init fails
Before:
qemu-system-x86_64: -display vnc=unix:/root/foo.sock: Failed to start VNC server on `(null)': Failed to bind socket to /root/foo.sock: Permission denied

After:
qemu-system-x86_64: -display vnc=unix:/root/foo.sock: Failed to start VNC server: Failed to bind socket to /root/foo.sock: Permission denied

Rather than tweak the string possibly show unix: value as well,
just drop the explicit display reporting. We already get the cli
string in the error message, that should be sufficient.

8617989eae ui/cocoa: Avoid deprecated NSOKButton/NSCancelButton constants
In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated
and provoke compiler warnings. Avoid them by using the
NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

2a4c8c53da ui/cocoa: Declare that QemuCocoaAppController implements NSApplicationDelegate
Our class QemuCocoaAppController implements the NSApplicationDelegate
interface, and we pass an object of this class to [NSApp setDelegate].
However, we weren't declaring in the class definition that we implemented
this interface; in OSX 10.10 this provokes the following (slighly
misleading) warning:
ui/cocoa.m:1031:24: warning: sending 'QemuCocoaAppController *' to parameter of
      incompatible type 'id<NSFileManagerDelegate>'

                                              ^

Annoyingly, this interface wasn't formally defined until OSX 10.6, so we
have to surround the relevant part of the @interface line with an ifdef.

b63901d84c ui/cocoa: Drop tests for CGImageCreateWithImageInRect support
The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:

ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
      equal to a null pointer is always false[-Wtautological-pointer-compare]
        if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~    ~~~~

The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)

3b5704b2f8 monitor: Make client_migrate_info synchronous
Live migration with spice works like this today:

  (1) client_migrate_info monitor cmd
  (2) spice server notifies client, client connects to target host.
  (3) qemu waits until spice client connect is finished.
  (4) send over vmstate (i.e. main part of live migration).
  (5) spice handover to target host.

(3) is implemented by making client_migrate_info a async monitor
command.  This is the only async monitor command we have.

The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel.  That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.

Time to drop step (3).  This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

2cdb5e142f CVE-2015-1779: limit size of HTTP headers from websockets clients
The VNC server websockets decoder will read and buffer data from
websockets clients until it sees the end of the HTTP headers,
as indicated by \r\n\r\n. In theory this allows a malicious to
trick QEMU into consuming an arbitrary amount of RAM. In practice,
because QEMU runs g_strstr_len() across the buffered header data,
it will spend increasingly long burning CPU time searching for
the substring match and less & less time reading data. So while
this does cause arbitrary memory growth, the bigger problem is
that QEMU will be burning 100% of available CPU time.

A novnc websockets client typically sends headers of around
512 bytes in length. As such it is reasonable to place a 4096
byte limit on the amount of data buffered while searching for
the end of HTTP headers.

a2bebfd6e0 CVE-2015-1779: incrementally decode websocket frames
The logic for decoding websocket frames wants to fully
decode the frame header and payload, before allowing the
VNC server to see any of the payload data. There is no
size limit on websocket payloads, so this allows a
malicious network client to consume 2^64 bytes in memory
in QEMU. It can trigger this denial of service before
the VNC server even performs any authentication.

The fix is to decode the header, and then incrementally
decode the payload data as it is needed. With this fix
the websocket decoder will allow at most 4k of data to
be buffered before decoding and processing payload.

51941e4695 ui: enforce TLS when using websockets server
When TLS is required, the primary VNC server considers it to be
mandatory. ie the server admin decides whether or not TLS is used,
and the client has to comply with this decision. The websockets
server, however, treated it as optional, allowing non-TLS clients
to connect to a server which had setup TLS. Thus enabling websockets
lowers the security of the VNC server leaving the admin no way to
enforce use of TLS.

This removes the code that allows non-TLS fallback in the websockets
server, so that if TLS is requested for VNC it is now mandatory for
both the primary VNC server and the websockets VNC server.

f9148c8ae7 ui: fix setup of VNC websockets auth scheme with TLS
The way the websockets TLS code was integrated into the VNC server
made it essentially useless. The only time that the websockets TLS
support could be used is if the primary VNC server had its existing
TLS support disabled. ie QEMU had to be launched with:

  # qemu -vnc localhost:1,websockets=5902,x509=/path/to/certs

Note the absence of the 'tls' flag. This is already a bug, because
the docs indicate that 'x509' is ignored unless 'tls' is given.

If the primary VNC server had TLS turned on via the 'tls' flag,
then this prevented the websockets TLS support from being used,
because it activates the VeNCrypt auth which would have resulted
in TLS being run over a TLS session. Of course no websockets VNC
client supported VeNCrypt so in practice, since the browser clients
cannot setup a nested TLS session over the main HTTPS connection,
so it would not even get past auth.

This patch causes us to decide our auth scheme separately for the
main VNC server vs the websockets VNC server. We take account of
the fact that if TLS is enabled, then the websockets client will
use https, so setting up VeNCrypt is thus redundant as it would
lead to nested TLS sessions.

d169f04b8b ui: report error if user requests VNC option that is unsupported
If the VNC server is built without tls, sasl or websocket support
and the user requests one of these features, they are just silently
ignored. This is bad because it means the VNC server ends up running
in a configuration that is less secure than the user asked for.
It also leads to an tangled mass of preprocessor conditionals when
configuring the VNC server.

This ensures that the tls, sasl & websocket options are always
processed and an error is reported back to the user if any of
them were disabled at build time.

e5f34cdd2d vnc: track & limit connections
Also track the number of connections in "connecting" and "shared" state
(in addition to the "exclusive" state).  Apply a configurable limit to
these connections.

The logic to apply the limit to connections in "shared" state is pretty
simple:  When the limit is reached no new connections are allowed.

The logic to apply the limit to connections in "connecting" state (this
is the state you are in *before* successful authentication) is
slightly different:  A new connect kicks out the oldest client which is
still in "connecting" state.  This avoids a easy DoS by unauthenticated
users by simply opening connections until the limit is reached.

Replace with a vnc_displays list, so we can have multiple vnc server

d3f3a0f453 sdl2: Work around SDL2 SDL_ShowWindow() bug
Apparently it is possible for X to send an event to a hidden SDL2
window, leading to SDL2 believing it is now shown. SDL2 will pass the
SDL_WINDOWEVENT_SHOWN message to the application without actually
showing the window; the problem is that the next SDL_ShowWindow() will
be a no-op because SDL2 assumes the window is already shown.

The correct way to react to SDL_WINDOWEVENT_SHOWN would be to clear
scon->hidden (analogous for SDL_WINDOWEVENT_HIDDEN). However, due to the
window not actually being shown, this will somehow not be correct after
all.

Therefore, just hide the window on SDL_WINDOWEVENT_SHOWN if it is
supposed to be hidden (and analogous for SDL_WINDOWEVENT_HIDDEN).

1dfc5c8808 sdl2: Use correct sdl2_console for window events
SDL_PollEvent() polls events for all windows; therefore,
sdl2_poll_events() will poll the events for all windows and not only for
the one identified by the given sdl2_console.

This should be considered in handle_windowevent(): The window affected
by the event is not necessarily the one identified by the sdl2_console
object given to sdl2_poll_events(), but the one identified by
ev->window.windowID.
