2015-01-22monitor: add query-vnc-servers commandGerd Hoffmann1-0/+133
Add new query vnc qmp command, for the lack of better ideas just name it "query-vnc-servers". Changes over query-vnc: * It returns a list of vnc servers, so multiple vnc server instances are covered. * Each vnc server returns a list of server sockets. Followup patch will use that to also report websockets. In case we add support for multiple server sockets server sockets (to better support ipv4+ipv6 dualstack) we can add them to the list too.

2015-01-22vnc: track & limit connectionsGerd Hoffmann2-3/+46
Also track the number of connections in "connecting" and "shared" state (in addition to the "exclusive" state). Apply a configurable limit to these connections. The logic to apply the limit to connections in "shared" state is pretty simple: When the limit is reached no new connections are allowed. The logic to apply the limit to connections in "connecting" state (this is the state you are in *before* successful authentication) is slightly different: A new connect kicks out the oldest client which is still in "connecting" state. This avoids a easy DoS by unauthenticated users by simply opening connections until the limit is reached.

2014-12-17sdl2: Work around SDL2 SDL_ShowWindow() bugMax Reitz1-0/+10
Apparently it is possible for X to send an event to a hidden SDL2 window, leading to SDL2 believing it is now shown. SDL2 will pass the SDL_WINDOWEVENT_SHOWN message to the application without actually showing the window; the problem is that the next SDL_ShowWindow() will be a no-op because SDL2 assumes the window is already shown. The correct way to react to SDL_WINDOWEVENT_SHOWN would be to clear scon->hidden (analogous for SDL_WINDOWEVENT_HIDDEN). However, due to the window not actually being shown, this will somehow not be correct after all. Therefore, just hide the window on SDL_WINDOWEVENT_SHOWN if it is supposed to be hidden (and analogous for SDL_WINDOWEVENT_HIDDEN).

2014-12-17sdl2: Use correct sdl2_console for window eventsMax Reitz1-2/+4
SDL_PollEvent() polls events for all windows; therefore, sdl2_poll_events() will poll the events for all windows and not only for the one identified by the given sdl2_console. This should be considered in handle_windowevent(): The window affected by the event is not necessarily the one identified by the sdl2_console object given to sdl2_poll_events(), but the one identified by ev->window.windowID.

2014-12-16spice: fix memory leakGonglei1-4/+1
If errors happen for middle items of channel_list, qmp_query_spice_channels() returns NULL, and the variable cur_item going out of scope leaks the storage it points to. The flag is a compatibility thing for older spice-server versions. Meanwhile our minimum spice version requirement is new enough that we should never ever see this error, and if we do something went very seriously wrong. Let's using assert() instead of returning NULL to avoid a memory leak.

2014-12-16spice: use bottom half instead of refresh timer for cursor updatesGerd Hoffmann1-2/+10

2014-11-13QMP/input-send-event: make console parameter optionalAmos Kong1-6/+9
The 'QemuConsole' is the input source for handler, we share some input handlers to process the input events from different QemuConsole. Normally we only have one set of keyboard, mouse, usbtablet, etc. The devices have different mask, it's fine to just checking mask to insure that the handler has the ability to process the event. I saw we try to bind console to handler in usb/dev-hid.c, but display always isn't available at that time. If we have multiseat setup (as Gerd said), we only have 'problem' in this case. Actually event from different devices have the same effect for system, it's fine to always use the first available handler without caring about the console. For send-key command, we just pass a NULL for console parameter in calling qemu_input_event_send_key(NULL, ..), but 'input-send-event' needs to care more devices. Conclusion: Generally assigning the special console is meanless, and we can't directly remove the QMP parameter for compatibility. So we can make the parameter optional. The parameter might be useful for some special condition: we have multiple devices without binding console and they all have the ability(mask) to process events, and we don't want to use the first one.
