6e1db57b2a qemu-char: Print strerror message on failure
The only way for chardev drivers to communicate an error was to return a NULL
pointer, which resulted in an error message that said _that_ something went
wrong, but not _why_.

This patch changes the interface to return 0/-errno and updates
qemu_chr_open_opts to use strerror to display a more helpful error message.

2fb0c09f4f vnc: Fix compilation with --enable-vnc-png
Commit f26e428da5 fixed compilation
with --enable-vnc-png, but broke it with --enable-vnc-png.

The breakage is caused by pngconfig.h which checks whether
setjmp.h was already included and fails because qemu-common.h
includes setjmp.h.

The check is disabled by defining PNG_SKIP_SETJMP_CHECK.

48b3ed0a68 spice: add SASL support
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.

2caa9e9d2e vnc: tight: Fix crash after 2GB of output
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.

d6e58090fe severe memory leak caused by broken palette_destroy() function
The following commit breaks the code of the function palette_destroy().

http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commit;h=e31e3694afef58ba191cbcc6875ec243e5971268

The broken code causes a severe memory leak of 'VncPalette' structures
because it never frees anything:

     70 void palette_destroy(VncPalette *palette)
     71 {
     72     if (palette == NULL) {
     73         qemu_free(palette);
     74     }
     75 }

Version 2 of the patch calls qemu_free() unconditionally.

23bfe28fff vnc: Fix stack corruption and other bitmap related bugs
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.

4e79bcbb96 ui/sdl: Fix handling of caps lock and num lock keys
Starting with SDL version 1.2.14, caps lock and num lock keys
will send a SDL_KEYUP when SDL_DISABLE_LOCK_KEYS=1 is set in
the environment.

The new code sets the environment unconditionally
(it won't harm old versions which do not know it).

The workaround for SDL_KEYUP is only compiled with old SDL versions.

A similar patch without handling of old SDL versions was already
published by Benjamin Drung for Ubuntu.

1cd20f8bf0 vnc: Fix password expiration through 'change vnc ""' (v2)
commit 52c18be9e9 introduced a regression in the
change vnc password command that changed the behavior of setting the VNC
password to an empty string from disabling login to disabling authentication.

This commit refactors the code to eliminate this overloaded semantics in
vnc_display_password and instead introduces the vnc_display_disable_login.   The
monitor implementation then determines the behavior of an empty or missing
string.

Recently, a set_password command was added that allows both the Spice and VNC
password to be set.  This command has not shown up in a release yet so the
behavior is not yet defined.

This patch proposes that an empty password be treated as an empty password with
no special handling.  For specifically disabling login, I believe a new command
should be introduced instead of overloading semantics.

I'm not sure how Spice handles this but I would recommend that we have Spice
and VNC have consistent semantics here for the 0.14.0 release.

9892088b52 vnc: fix numlock+capslock tracking
This patch makes the numlock+capslock tracking logic only look at
keydown events.  Without this patch the vnc server will insert
bogous capslock keypress in case it sees the following key sequence:

  shift down --- 'A' down --- shift up  --- 'A' up
                                         ^ here

It doesn't hurt with a PS/2 keyboard, but it disturbs the USB Keyboard.
And with the key event queue just added to the usb keyboard the guest
will actually notice.

a19cbfb346 spice: add qxl device
qxl is a paravirtual graphics card.  The qxl device is the bridge
between the guest and the spice server (aka libspice-server).  The
spice server will send the rendering commands to the spice client, which
will actually render them.

The spice server is also able to render locally, which is done in case
the guest wants read something from video memory.  Local rendering is
also used to support display over vnc and sdl.

qxl is activated using "-vga qxl".  qxl supports multihead, additional
cards can be added via '-device qxl".

[ v2: add copyright to files                     ]

This results in a compiler warning (redefinition of

compilations for win32 with warning = error).

Fix this by removing the definition of WIN32_LEAN_AND_MEAN
