Daniel P. Berrange 12e29b1682 vnc: ensure connection sharing/limits is always configured
The connection sharing / limits are only set in the
vnc_display_open() method and so missed when VNC is running
with '-vnc none'. This in turn prevents clients being added
to the VNC server with the QMP "add_client" command.

Daniel P. Berrange 3e7f136d8b vnc: fix crash when vnc_server_info_get has an error
The vnc_server_info_get will allocate the VncServerInfo
struct and then call vnc_init_basic_info_from_server_addr
to populate the basic fields. If this returns an error
though, the qapi_free_VncServerInfo call will then crash
because the VncServerInfo struct instance was not properly
NULL-initialized and thus contains random stack garbage.

Peter Lieven 66668d197f vnc-tight: fix regression with libxenstore
commit 095497ff added thread local storage for the color counting
palette. Unfortunately, a VncPalette is about 7kB on a x86_64 system.
This memory is reserved from the stack of every thread and it
exhausted the stack space of a libxenstore thread.

Fix this by allocating memory only for the VNC encoding thread.

Herongguang (Stephen) 3f7e51bca3 vnc-enc-tight: fix off-by-one bug
In tight_encode_indexed_rect32, buf(or src)’s size is count. In for loop,
the logic is supposed to be that i is an index into src, i should be
incremented when incrementing src.

This is broken when src is incremented but i is not before while loop,
resulting in off-by-one bug in while loop.

Gerd Hoffmann 5a8be0f73d vnc: make sure we finish disconnect
It may happen that vnc connections linger in disconnecting state forever
because VncState happens to be in a state where vnc_update_client()
exists early and never reaches the vnc_disconnect_finish() call at the
bottom of the function.  Fix that by doing an additinal check at the
start of the function.

Daniel P. Berrange ea69744988 ui: avoid crash if vnc client disconnects with writes pending
The vnc_client_read() function is called from the vnc_client_io()
event handler callback when there is incoming data to process.
If it detects that the client has disconnected, then it will
trigger cleanup and free'ing of the VncState client struct at
a safe time.

Unfortunately, the vnc_client_io() event handler will also call
vnc_client_write() to handle any outgoing data writes. So if
vnc_client_io() was invoked with both G_IO_IN and G_IO_OUT
events set, and the client disconnects, we may try to write to
a client which has just been freed.

Eduardo Habkost 9be385980d coccinelle: Remove unnecessary variables for function return value
Use Coccinelle script to replace 'ret = E; return ret' with
'return E'. The script will do the substitution only when the
function return type and variable type are the same.

Manual fixups:

* audio/audio.c: coding style of "read (...)" and "write (...)"
* block/qcow2-cluster.c: wrap line to make it shorter
* block/qcow2-refcount.c: change indentation of wrapped line
* target-tricore/op_helper.c: fix coding style of
  "remainder|quotient"
* target-mips/dsp_helper.c: reverted changes because I don't
  want to argue about checkpatch.pl
* ui/qemu-pixman.c: fix line indentation
* block/rbd.c: restore blank line between declarations and

Alexander Graf 0c426e4534 vnc: Add support for color map
Our current VNC code does not handle color maps (aka non-true-color) at all
and aborts if a client requests them. There are 2 major issues with this:

 1) A VNC viewer on an 8-bit X11 system may request color maps
 2) RealVNC _always_ starts requesting color maps, then moves on to full color

In order to support these 2 use cases, let's just create a fake color map
that covers exactly our normal true color 8 bit color space. That way we don't
lose anything over a client that wants true color.

Actually this is a very old patch originally submitted in 2013 by
Alexander. The situation is still the same with RealVNC, it does not
connect by default to QEMU VNC. The problem is that this client is
really popular. This is better to be kludged.
