      Move VNC structs into header file ("Daniel P. Berrange") · 19a490bf
      由 aliguori 提交于 
      This patch moves the definitions of VncState and VncDisplay structs
out into a vnc.h header file. This is to allow the code for TLS
and SASL auth mechanisms to be moved out of the main vnc.c file.

      Refactor keymap code to avoid duplication ("Daniel P. Berrange") · 0483755a
      由 aliguori 提交于 
      Each of the graphical frontends #include a .c file, for keymap code
resulting in duplicated definitions & duplicated compiled code. A
couple of small changes allowed this to be sanitized, so instead of
doing a #include "keymaps.c", duplicating all code, we can have a
shared keymaps.h file, and only compile code once. This allows the
next patch to move the VncState struct out into a header file without
causing clashing definitions.

      Enhance 'info vnc' monitor output ("Daniel P. Berrange") · 1ff7df1a
      由 aliguori 提交于 
      The current 'info vnc' monitor output just displays the VNC server address
as provided by the -vnc command line flag. This isn't particularly useful
since it doesn't tell you what VNC is actually listening on. eg, if you
use '-vnc :1' it is useful to know whether this translated to '0.0.0.0:5901'
or chose IPv6 ':::5901'.  It is also useful to know the address of the
client that is currently connected. It is also useful to know the active
authentication (if any).

This patch tweaks the monitor output to look like:

   (qemu) info vnc
    Server:
         address: 0.0.0.0:5902
            auth: vencrypt+x509
    Client: none

And when 2 clients are connected

   (qemu) info vnc
    Server:
         address: 0.0.0.0:5902
            auth: vencrypt+x509
    Client:
         address: 10.33.6.67:38621
    Client:
         address: 10.33.6.63:38620

More data will be added to this later in the patch series...

The 'addr_to_string' helper method in this patch is overly generic
for the needs of this patch alone. This is because it will be re-used
by the later SASL patches in this series, where the flexibility is
important.

      Fix bug in TLS authentication ("Daniel P. Berrange") · adc5ec85
      由 aliguori 提交于 
      This patch was previously posted here:

  http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg00820.html

In the case where the TLS handshake does *not* block on I/O, QEMU
sends the next 'start sub-auth' message twice. This seriously confuses
the VNC client :-) Fortunately the chances of the handshake not blocking
are close to zero for a TCP socket, which is why it has not been noticed
thus far. Even with both client & server on localhost, I can only hit the
bug 1 time in 20.

NB, the diff context here is not too informative. If you look at the
full code you'll see that a few lines early we called vnc_start_tls()
which called vnc_continue_handshake() which called the method
start_auth_vencrypt_subauth(). Hence, fixing the bug, just involves
removing the 2nd bogus call to start_auth_vencrypt_subauth() as per
this patch.

      monitor: Rework API (Jan Kiszka) · 376253ec
      由 aliguori 提交于 
      Refactor the monitor API and prepare it for decoupled terminals:
term_print functions are renamed to monitor_* and all monitor services
gain a new parameter (mon) that will once refer to the monitor instance
the output is supposed to appear on. However, the argument remains
unused for now. All monitor command callbacks are also extended by a mon
parameter so that command handlers are able to pass an appropriate
reference to monitor output services.

For the case that monitor outputs so far happen without clearly
identifiable context, the global variable cur_mon is introduced that
shall once provide a pointer either to the current active monitor (while
processing commands) or to the default one. On the mid or long term,
those use case will be obsoleted so that this variable can be removed
again.

Due to the broad usage of the monitor interface, this patch mostly deals
with converting users of the monitor API. A few of them are already
extended to pass 'mon' from the command handler further down to internal
functions that invoke monitor_printf.

At this chance, monitor-related prototypes are moved from console.h to
a new monitor.h. The same is done for the readline API.

      exploiting the new interface in vnc.c (Stefano Stabellini) · 6cec5487
      由 aliguori 提交于 
      This patch exploits the new DisplaySurface and PixelFormat structures in
vnc, making the code easier to read allowing further improvements.

Compared to the last version I fixed a bug that prevented the hextile
encoding from working properly.

      DisplayState interface change (Stefano Stabellini) · 7d957bd8
      由 aliguori 提交于 
      This patch changes the DisplayState interface adding support for
multiple frontends at the same time (sdl and vnc) and implements most
of the benefit of the shared_buf patch without the added complexity.

Currently DisplayState is managed by sdl (or vnc) and sdl (or vnc) is
also responsible for allocating the data and setting the depth.
Vga.c (or another backend) will do any necessary conversion.

The idea is to change it so that is vga.c (or another backend) together
with console.c that fully manage the DisplayState interface allocating
data and setting the depth (either 16 or 32 bit, if the guest uses a
different resolution or is in text mode, vga.c (or another backend) is
in charge of doing the conversion seamlessly).

The other idea is that DisplayState supports *multiple* frontends
like sdl and vnc; each of them can register some callbacks to be called
when a display event occurs.

The interesting changes are:

- the new structures and related functions in console.h and console.c

in particular the following functions are very helpful to manage a
DisplaySurface:

qemu_create_displaysurface
qemu_resize_displaysurface
qemu_create_displaysurface_from
qemu_free_displaysurface

- console_select and qemu_console_resize in console.c
this two functions manage multiple consoles on a single host display

- moving code around in hw/vga.c
as for the shared_buf patch this is necessary to be able to handle a dynamic
DisplaySurface bpp

- changes to vga_draw_graphic in hw/vga.c
this is the place where the DisplaySurface buffer is shared with the
videoram, when possible;


Compared to the last version the only changes are:

- do not remove support to dpy_copy in cirrus_vga
- change the name of the displaysurface handling functions
