2016-09-28ui/vnc-enc-tight: remove switch and have single returnAlex Bennée
When enabling the sanitizer build it will complain about control reaching a non-void function. Normally the compiler should detect that there is only one possible exit given a static VNC_SERVER_FB_BYTES. As we always expect a static VNC_SERVER_FB_BYTES I've added a compile time assert and just called the sub-function directly.

2016-09-28spice/gl: render DisplaySurface via openglGerd Hoffmann
This switches over spice (in opengl mode) to render DisplaySurface updates into a opengl texture, using the helper functions in ui/console-gl.c. With this patch applied spice (with gl=on) will stop using qxl rendering ops, it will use dma-buf passing all the time, i.e. for bios/bootloader (before virtio-gpu driver is loaded) too. This should improve performance even using spice (with gl=on) with non-accelerated stdvga because we stop squeezing all display updates through a unix/tcp socket and basically using a shared memory transport instead.

2016-09-28console: track gl_block state in QemuConsoleGerd Hoffmann
Keep track of gl_block state (added in bba19b8 console: block rendering until client is done) in QemuConsole and allow to query it. This way we can avoid state inconsistencies in case different code paths make use of this.

2016-09-28console: skip same-size resizeMarc-André Lureau
virtio-gpu does a set-scanout at each frame (it might be a driver regression). qemu_console_resize() recreate a surface even if the size didn't change, and this shows up in profiling reports because the surface is cleared. With this patch, I get a +15-20% glmark2 improvement.

2016-09-13ui/curses.c: Clean up nextchr logicPeter Maydell
Coverity identifies that at the top of the while(1) loop in curses_refresh() the variable nextchr is always ERR, and so the else case of the first if() is dead code. Remove this dead code, and narrow the scope of the nextchr variable to the place where it's used. (This confused logic has been present since the curses code was added to QEMU in 2008.)

2016-08-30ui: fix refresh of VNC server surfaceDaniel P. Berrange
In previous commit commit c7628bff4138ce906a3620d12e0820c1cf6c140d Author: Gerd Hoffmann <kraxel@redhat.com> Date: Fri Oct 30 12:10:09 2015 +0100 vnc: only alloc server surface with clients connected the VNC server was changed so that the 'vd->server' pixman image was only allocated when a client is connected. Since then if a client disconnects and then reconnects to the VNC server all they will see is a black screen until they do something that triggers a refresh. On a graphical desktop this is not often noticed since there's many things going on which cause a refresh. On a plain text console it is really obvious since nothing refreshes frequently. The problem is that the VNC server didn't update the guest dirty bitmap, so still believes its server image is in sync with the guest contents. To fix this we must explicitly mark the entire guest desktop as dirty after re-creating the server surface. Move this logic into vnc_update_server_surface() so it is guaranteed to be call in all code paths that re-create the surface instead of only in vnc_dpy_switch() Signed-off-by: Daniel P.

2016-08-03vnc: fix crash when vnc_server_info_get has an errorDaniel P. Berrange
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. #0 0x00007f1987c8e6f5 in raise () at /lib64/libc.so.6 #1 0x00007f1987c902fa in abort () at /lib64/libc.so.6 #2 0x00007f1987ccf600 in __libc_message () at /lib64/libc.so.6 #3 0x00007f1987cd7d4a in _int_free () at /lib64/libc.so.6 #4 0x00007f1987cdb2ac in free () at /lib64/libc.so.6 #5 0x00007f198b654f6e in g_free () at /lib64/libglib-2.0.so.0 #6 0x0000559193cdcf54 in visit_type_str (v=v@entry= 0x5591972f14b0, name=name@entry=0x559193de1e29 "host", obj=obj@entry=0x5591961dbfa0, errp=errp@entry=0x7fffd7899d80) at qapi/qapi-visit-core.c:255 #7 0x0000559193cca8f3 in visit_type_VncBasicInfo_members (v=v@entry= 0x5591972f14b0, obj=obj@entry=0x5591961dbfa0, errp=errp@entry=0x7fffd7899dc0) at qapi-visit.c:12307 #8 0x0000559193ccb523 in visit_type_VncServerInfo_members (v=v@entry= 0x5591972f14b0, obj=0x5591961dbfa0, errp=errp@entry=0x7fffd7899e00) at qapi-visit.c:12632 #9 0x0000559193ccb60b in visit_type_VncServerInfo (v=v@entry= 0x5591972f14b0, name=name@entry=0x0, obj=obj@entry=0x7fffd7899e48, errp=errp@entry=0x0) at qapi-visit.c:12658 #10 0x0000559193cb53d8 in qapi_free_VncServerInfo (obj=<optimized out>) at qapi-types.c:3970 #11 0x0000559193c1e6ba in vnc_server_info_get (vd=0x7f1951498010) at ui/vnc.c:233 #12 0x0000559193c24275 in vnc_connect (vs=0x559197b2f200, vs=0x559197b2f200, event=QAPI_EVENT_VNC_CONNECTED) at ui/vnc.c:284 #13 0x0000559193c24275 in vnc_connect (vd=vd@entry=0x7f1951498010, sioc=sioc@entry=0x559196bf9c00, skipauth=skipauth@entry=tru e, websocket=websocket@entry=false) at ui/vnc.c:3039 #14 0x0000559193c25806 in vnc_display_add_client (id=<optimized out>, csock=<optimized out>, skipauth=<optimized out>) at ui/vnc.c:3877 #15 0x0000559193a90c28 in qmp_marshal_add_client (args=<optimized out>, ret=<optimized out>, errp=0x7fffd7899f90) at qmp-marshal.c:105 #16 0x000055919399c2b7 in handle_qmp_command (parser=<optimized out>, tokens=<optimized out>) at /home/berrange/src/virt/qemu/monitor.c:3971 #17 0x0000559193ce3307 in json_message_process_token (lexer=0x559194ab0838, input=0x559194a6d940, type=JSON_RCURLY, x=111, y=1 2) at qobject/json-streamer.c:105 #18 0x0000559193cfa90d in json_lexer_feed_char (lexer=lexer@entry=0x559194ab0838, ch=125 '}', flush=flush@entry=false) at qobject/json-lexer.c:319 #19 0x0000559193cfaa1e in json_lexer_feed (lexer=0x559194ab0838, buffer=<optimized out>, size=<optimized out>) at qobject/json-lexer.c:369 #20 0x0000559193ce33c9 in json_message_parser_feed (parser=<optimized out>, buffer=<optimized out>, size=<optimized out>) at qobject/json-streamer.c:124 #21 0x000055919399a85b in monitor_qmp_read (opaque=<optimized out>, buf=<optimized out>, size=<optimized out>) at /home/berrange/src/virt/qemu/monitor.c:3987 #22 0x0000559193a87d00 in tcp_chr_read (chan=<optimized out>, cond=<optimized out>, opaque=0x559194a7d900) at qemu-char.c:2895 #23 0x00007f198b64f703 in g_main_context_dispatch () at /lib64/libglib-2.0.so.0 #24 0x0000559193c484b3 in main_loop_wait () at main-loop.c:213 #25 0x0000559193c484b3 in main_loop_wait (timeout=<optimized out>) at main-loop.c:258 #26 0x0000559193c484b3 in main_loop_wait (nonblocking=<optimized out>) at main-loop.c:506 #27 0x0000559193964c55 in main () at vl.c:1908 #28 0x0000559193964c55 in main (argc=<optimized out>, argv=<optimized out>, envp=<optimized out>) at vl.c:4603 This was introduced in commit 98481bfcd661daa3c160cc87a297b0e60a307788 Author: Eric Blake <eblake@redhat.com> Date: Mon Oct 26 16:34:45 2015 -0600 vnc: Hoist allocation of VncBasicInfo to callers which added error reporting for vnc_init_basic_info_from_server_addr but didn't change the g_malloc calls to g_malloc0.

2016-07-15vnc-tight: fix regression with libxenstorePeter Lieven
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.

2016-07-15vnc: make sure we finish disconnectGerd Hoffmann
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. https://bugzilla.redhat.com/show_bug.cgi?id=1352799 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 1468405280-2571-1-git-send-email-kraxel@redhat.com

2016-07-12ui: avoid crash if vnc client disconnects with writes pendingDaniel P. Berrange
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. https://bugs.launchpad.net/qemu/+bug/1594861 Signed-off-by: Daniel P.

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.
