2017-03-17ui/console: ensure graphic updates don't race with TCG vCPUsAlex Bennée1-1/+20
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 Hoffmann2-128/+0
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client we have to send all outstanding updates beforehand, otherwise the vnc client might run the client side blit on outdated data and thereby corrupt the display.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 ...

XkbGetKeyboard does not work in XWayland and even on non-Wayland X11 servers its use is discouraged: https://bugs.freedesktop.org/show_bug.cgi?id=89240 This resolves a problem whereby QEMU prints "could not lookup keycode name" on startup when running under XWayland.

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.

2017-02-09ui: refactor code for populating SocketAddress from vnc_display_openDaniel P. Berrange1-101/+181
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. Berrange2-40/+73
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.

2017-02-08ui: fix reporting of VNC auth in query-vnc-serversDaniel P. Berrange1-35/+50
Currently the VNC authentication info is emitted at the top level of the query-vnc-servers data. This is wrong because the authentication scheme differs between plain and websockets when TLS is enabled. We should instead report auth against the individual servers. e.g. (QEMU) query-vnc-servers { "return": [ { "clients": [], "id": "default", "auth": "vencrypt", "vencrypt": "x509-vnc", "server": [ { "host": "127.0.0.1" "service": "5901", "websocket": false, "family": "ipv4", "auth": "vencrypt", "vencrypt": "x509-vnc" }, { "host": "127.0.0.1", "service": "5902", "websocket": true, "family": "ipv4", "auth": "vnc" } ] } ] } This also future proofs the QMP schema so that we can cope with multiple VNC server instances, listening on different interfaces or ports, with different auth setup.

The -vnc argument is documented as accepting two syntaxes for the 'websocket' option, either a bare option name, or a port number. If using the bare option name, it is supposed to apply the display number as an offset to base port 5700. e.g. -vnc localhost:3,websocket should listen on port 5703, however, this was broken in 2.3.0 since commit 4db14629c38611061fc19ec6927405923de84f08 Author: Gerd Hoffmann <kraxel@redhat.com> Date: Tue Sep 16 12:33:03 2014 +0200 vnc: switch to QemuOpts, allow multiple servers instead qemu tries to listen on port "on" which gets looked up in /etc/services and fails.

2017-02-08vnc: do not disconnect on EAGAINMichael Tokarev1-1/+2
When qemu vnc server is trying to send large update to clients, there might be a situation when system responds with something like EAGAIN, indicating that there's no system memory to send that much data (depending on the network speed, client and server and what is happening). In this case, something like this happens on qemu side (from strace): sendmsg(16, {msg_name(0)=NULL, msg_iov(1)=[{"\244\"..., 729186}], msg_controllen=0, msg_flags=0}, 0) = 103950 sendmsg(16, {msg_name(0)=NULL, msg_iov(1)=[{"lz\346"..., 1559618}], msg_controllen=0, msg_flags=0}, 0) = -1 EAGAIN sendmsg(-1, {msg_name(0)=NULL, msg_iov(1)=[{"lz\346"..., 1559618}], msg_controllen=0, msg_flags=0}, 0) = -1 EBADF qemu closes the socket before the retry, and obviously it gets EBADF when trying to send to -1. This is because there WAS a special handling for EAGAIN, but now it doesn't work anymore, after commit 04d2529da27db512dcbd5e99d0e26d333f16efcc, because now in all error-like cases we initiate vnc disconnect. This change were introduced in qemu 2.6, and caused numerous grief for many people, resulting in their vnc clients reporting sporadic random disconnects from vnc server. Fix that by doing the disconnect only when necessary, i.e. omitting this very case of EAGAIN. Hopefully the existing condition (comparing with QIO_CHANNEL_ERR_BLOCK) is sufficient, as the original code (before the above commit) were checking for other errno values too. Apparently there's another (semi?)bug exist somewhere here, since the code tries to write to fd# -1, it probably should check if the connection is open before. But this isn't important.

2017-01-31gtk: Hardcode LC_CTYPE as C.utf-8Kevin Wolf1-1/+5
Commit 2cb5d2a4 removed setlocale() for everything except LC_MESSAGES in order to avoid unwanted side effects such as using the wrong decimal separator in generated JSON objects. However, the problem that unsetting LC_CTYPE caused is that non-ASCII characters are considered non-printable now and therefore the GTK menus display question marks for accented letters, Chinese characters etc. A first attempt to fix this [1] was rejected because even just setting LC_CTYPE to the user's locale (and thereby modifying the semantics of the ctype.h functions) could have unwanted effects that we're not aware of yet. Recently, however, glibc introduced a new locale "C.utf-8" that just uses UTF-8 as its charset, but otherwise leaves the semantics alone. Just setting the right character set is enough for our use case, so we can just hardcode this one without having to be afraid of nasty side effects. Older systems that don't have the new locale will continue displaying question marks, but this should fix the problem for most users.

2017-01-27chardev: qom-ifyMarc-André Lureau2-48/+65
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.

2017-01-27vc: use a common prefix for chr callbacksMarc-André Lureau1-12/+12
vc_chr_write() is more appropriate than _puts() since no newline is appended, even though it's not used only as a callback. Keep "qemu_chr_parse" prefix, most chardev parse functions use this prefix atm.

2017-01-27char: allocate CharDriverState as a single objectMarc-André Lureau2-17/+34
Use a single allocation for CharDriverState, this avoids extra allocations & pointers, and is a step towards more object-oriented CharDriver. Gtk console is a bit peculiar, gd_vc_chr_set_echo() used to have a temporary VirtualConsole to save the echo bit. Instead now, we consider whether vcd->console is set or not, and restore the echo bit saved in VCDriverState when calling gd_vc_vte_init(). The casts added are temporary, they are replaced with QOM type-safe macros in a later patch in this series.

2017-01-23io: change the QIOTask callback signatureDaniel P. Berrange2-9/+12
Currently the QIOTaskFunc signature takes an Object * for the source, and an Error * for any error. We also need to be able to provide a result pointer. Rather than continue to add parameters to QIOTaskFunc, remove the existing ones and simply pass the QIOTask object instead. This has methods to access all the other data items required in the callback impl. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

2017-01-10curses: Fix compiler warnings (Mingw-w64 redefinition of macro KEY_EVENT)Stefan Weil1-1/+0
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.

2017-01-10ui/vnc: Fix problem with sending too many bytes as server nameThomas Huth1-2/+6
If the buffer is not big enough, snprintf() does not return the number of bytes that have been written to the buffer, but the number of bytes that would be needed for writing the whole string. By using this value for the following vnc_write() calls, we send some junk at the end of the name in case the qemu_name is longer than 1017 bytes, which could confuse the VNC clients. Fix this by adding an additional size check here.
