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.

2017-03-16cirrus/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client we have to send all outstanding updates beforehand, otherwise the vnc client might run the client side blit on outdated data and thereby corrupt the display.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 ...

2017-01-27chardev: qom-ifyMarc-André Lureau
Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

For builds with Mingw-w64 as it is included in Cygwin, there are two header files which define KEY_EVENT with different values. This results in lots of compiler warnings like this one: CC vl.o In file included from /qemu/include/ui/console.h:340:0, from /qemu/vl.c:76: /usr/i686-w64-mingw32/sys-root/mingw/include/curses.h:1522:0: warning: "KEY_EVENT" redefined #define KEY_EVENT 0633 /* We were interrupted by an event */ In file included from /usr/share/mingw-w64/include/windows.h:74:0, from /usr/share/mingw-w64/include/winsock2.h:23, from /qemu/include/sysemu/os-win32.h:29, from /qemu/include/qemu/osdep.h:100, from /qemu/vl.c:24: /usr/share/mingw-w64/include/wincon.h:101:0: note: this is the location of the previous definition #define KEY_EVENT 0x1 QEMU only uses the KEY_EVENT macro from wincon.h. Therefore we can undefine the macro coming from curses.h. The explicit include statement for curses.h in ui/curses.c is not needed and was removed. Those two modifications fix the redefinition warnings.

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.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

2016-03-08input: linux evdev supportGerd Hoffmann
This patch adds support for reading input events directly from linux evdev devices and forward them to the guest. Unlike virtio-input-host which simply passes on all events to the guest without looking at them this will interpret the events and feed them into the qemu input subsystem. Therefore this is limited to what the qemu input subsystem and the emulated input devices are able to handle. Also there is no support for absolute coordinates (tablet/touchscreen). So we are talking here about basic mouse and keyboard support. The advantage is that it'll work without virtio-input drivers in the guest, the events are delivered to the usual ps/2 or usb input devices (depending on what the machine happens to have). And for keyboards qemu is able to switch the keyboard between guest and host on hotkey. The hotkey is hard-coded for now (both control keys), initialy the guest owns the keyboard. Probably most useful when assigning vga devices with vfio and using a physical monitor instead of vnc/spice/gtk as guest display. Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command line. Note that udev has rules which populate /dev/input/by-{id,path} with static names, which might be more convinient to use.

2016-02-23spice: add opengl/virgl/dmabuf supportGerd Hoffmann
This adds support for dma-buf passing to spice. This makes virtio-gpu with 3d acceleration work with spice. Workflow: * virglrenderer renders the guest command stream into a texture. * qemu exports the texture as dma-buf and passes on that dma-buf to spice-server. * spice-server passes the dma-buf to spice-client, using unix socket file descriptor passing. * spice-client asks the window systems composer to render the dma-buf to the screen. Requires cutting edge spice (server) and spice-gtk (client) builds, from git master branch. Also requires libvirt managing your qemu instance, and using "virt-viewer --attach $guest". libvirt will connect spice-server and spice-client using unix sockets instead of tcp sockets then, which is required for file descriptor passing. Works for the local case (spice server and client on the same machine) only. Supporting remote too is planned (by feeding the dma-bufs into gpu-assisted video encoder), but not there yet. gl mode is turned off by default, use "-spice gl=on,$otherargs" to enable it.

2016-02-03hmp: fix sendkey out of bounds write (CVE-2015-8619)Wolfgang Bumiller
When processing 'sendkey' command, hmp_sendkey routine null terminates the 'keyname_buf' array. This results in an OOB write issue, if 'keyname_len' was to fall outside of 'keyname_buf' array. Since the keyname's length is known the keyname_buf can be removed altogether by adding a length parameter to index_from_key() and using it for the error output as well.
