2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2017-05-12opengl: add egl-headless displayGerd Hoffmann
Add egl-headless user interface. It doesn't provide a real user interface, it only provides opengl support using drm render nodes. It will copy back the bits rendered by the guest using virgl back to a DisplaySurface and kick the usual display update code paths, so spice and vnc and screendump can pick it up. Use it this way: qemu -display egl-headless -vnc $display qemu -display egl-headless -spice gl=off,$args Note that you should prefer native spice opengl support (-spice gl=on) if possible because that delivers better performance.

2017-05-11ui: input-linux: Add absolute event supportPhilippe Voinov
This patch adds support for absolute pointer events to the input-linux subsystem. This support was omitted from the original input-linux patch, however most of the code required for it is already in place. Support for absolute events is especially useful for guests with vga passthrough. Since they have a physical monitor, none of normal channels for sending video output (vnc, etc) are used, meaning they also can't be used to send absolute input events. This leaves QMP as the only option to send absolute input into vga passthrough guests, which is not its intended use and is not efficient. This patch allows, for example, uinput to be used to create virtual absolute input devices. This lets you build external systems which share physical input devices between guests. Without absolute input capability, such external systems can't seamlessly share pointer devices between guests.

2017-05-09sockets: Limit SocketAddressLegacy to external interfacesMarkus Armbruster
SocketAddressLegacy is a simple union, and simple unions are awkward: they have their variant members wrapped in a "data" object on the wire, and require additional indirections in C.

2017-05-03input: don't queue delay if pausedMarc-André Lureau
qemu_input_event_send() discards key event when the guest is paused, but not the delay. The delay ends up in the input queue, and qemu_input_event_send_key() will further fill the queue with upcoming events. VNC uses qemu_input_event_send_key_delay(), not SPICE, which results in a different input behaviour on pause: VNC will queue the events (except the first that is discarded), SPICE will discard all events. Don't queue delay if paused, and provide same behaviour on SPICE and VNC clients on resume (and potentially avoid over-allocating the buffer queue) Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1444326 Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-id: 20170425130520.31819-1-marcandre.lureau@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

The previous commit (8bb93c6f99) using async_safe_run_on_cpu() doesn't work on graphics sub-system which restrict which threads can do GUI updates. Rather the special casing MacOS we just directly call the helper and move all the exclusive handling into do_dafe_dpy_refresh().

2017-03-28ui/console: ensure do_safe_dpy_refresh holds BQLAlex Bennée
I missed the fact that when an exclusive work item runs it drops the BQL to ensure all no vCPUs are stuck waiting for it, hence causing a deadlock. However the actual helper needs to take the BQL especially as we'll be messing with device emulation bits during the update which all assume BQL is held. We make a minor cpu_reloading_memory_map which must try and unlock the RCU if we are actually outside the running context.

vnc server in reverse mode (qemu -vnc localhost:$nr,reverse) interprets $nr as display number (i.e. with 5900 offset) in recent qemu versions. Historical and documented behavior is interpreting $nr as port number though. So we should bring code and documentation in line. Given that default listening port for viewers is 5500 the 5900 offset is pretty inconvinient, because it is simply impossible to connect to port 5500. So, lets fix the code not the docs.

2017-03-17ui/console: ensure graphic updates don't race with TCG vCPUsAlex Bennée
Commit 8d04fb55.. tcg: drop global lock during TCG code execution ..broke the assumption that updates to the GUI couldn't happen at the same time as TCG vCPUs where running. As a result the TCG vCPU could still be updating a directly mapped frame-buffer while the display side was updating. This would cause artefacts to appear when the update code assumed that memory block hadn't changed. The simplest solution is to ensure the two things can't happen at the same time like the old BQL locking scheme. Here we use the solution introduced for MTTCG and schedule the update as async_safe_work when we know no vCPUs can be running.

2017-03-16cirrus/vnc: zap bitblit support from console code.Gerd Hoffmann
There is a special code path (dpy_gfx_copy) to allow graphic emulation notify user interface code about bitblit operations carryed out by guests. It is supported by cirrus and vnc server. The intended purpose is to optimize display scrolls and just send over the scroll op instead of a full display update. This is rarely used these days though because modern guests simply don't use the cirrus blitter any more. Any linux guest using the cirrus drm driver doesn't. Any windows guest newer than winxp doesn't ship with a cirrus driver any more and thus uses the cirrus as simple framebuffer. So this code tends to bitrot and bugs can go unnoticed for a long time. See for example commit "3e10c3e vnc: fix qemu crash because of SIGSEGV" which fixes a bug lingering in the code for almost a year, added by commit "c7628bf vnc: only alloc server surface with clients connected". Also the vnc server will throttle the frame rate in case it figures the network can't keep up (send buffers are full). This doesn't work with dpy_gfx_copy, for any copy operation sent to the vnc client we have to send all outstanding updates beforehand, otherwise the vnc client might run the client side blit on outdated data and thereby corrupt the display. So this dpy_gfx_copy "optimization" might even make things worse on slow network links. Lets kill it once for all. Oh, and one more reason: Turns out (after writing the patch) we have a security bug in that code path ...

2017-02-09ui: add ability to specify multiple VNC listen addressesDaniel P. Berrange
This change allows the listen address and websocket address options for -vnc to be repeated. This causes the VNC server to listen on multiple addresses. e.g. $ $QEMU -vnc vnc=localhost:1,vnc=unix:/tmp/vnc,\ websocket=127.0.0.1:8080,websocket=[::]:8081 results in listening on 127.0.0.1:5901, 127.0.0.1:8080, ::1:5901, :::8081 & /tmp/vnc Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2017-02-09ui: let VNC server listen on all resolved IP addressesDaniel P. Berrange
Remove the limitation that the VNC server can only listen on a single resolved IP address. This uses the new DNS resolver API to resolve a SocketAddress struct into an array of SocketAddress structs containing raw IP addresses. The VNC server will then attempt to listen on all resolved IP addresses. The server must successfully listen on at least one of the resolved IP addresses, otherwise an error will be reported.

The code which takes a SocketAddress and connects/listens on the network is going to get more complicated to deal with multiple listeners.

2017-02-09ui: refactor code for populating SocketAddress from vnc_display_openDaniel P. Berrange
The code which interprets the CLI args to populate the SocketAddress objects for plain & websockets VNC is quite complex already and will need further enhancements shortly. Refactor it into separate methods to avoid vnc_display_open getting even larger. As a side effect of the refactoring, it is now possible to specify a listen address for the websocket server explicitly. e.g, -vnc localhost:5900,websockets=0.0.0.0:8080 will listen on localhost for the plain VNC server, but expose the websockets VNC server on the public interface. This refactoring also removes the restriction that prevents enabling websockets when the plain VNC server is listening on a UNIX socket.

2017-02-08ui: refactor VncDisplay to allow multiple listening socketsDaniel P. Berrange
Currently there is only a single listener for plain VNC and a single listener for websockets VNC. This means that if getaddrinfo() returns multiple IP addresses, for a hostname, the VNC server can only listen on one of them. This is just bearable if listening on wildcard interface, or if the host only has a single network interface to listen on, but if there are multiple NICs and the VNC server needs to listen on 2 or more specific IP addresses, it can't be done. This refactors the VncDisplay state so that it holds an array of listening sockets, but still only listens on one socket. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.
