2016-01-19vnc: distiguish between ipv4/ipv6 omitted vs set to offDaniel P. Berrange
The VNC code for interpreting QemuOpts does not currently distinguish between ipv4/ipv6 being omitted, and being set to 'off', because historically the 'ipv4' and 'ipv6' options were just flags which did not accept a value. The upshot is that if someone runs $QEMU -vnc localhost:1,ipv6=off QEMU still uses PF_UNSPEC and thus may still bind to IPv6, when it should use PF_INET. This is another instance of the problem previously fixed for chardevs in commit b77e7c8e99f9ac726c4eaa2fc3461fd886017dc0 Author: Paolo Bonzini <pbonzini@redhat.com> Date: Mon Oct 12 15:35:16 2015 +0200 qemu-sockets: fix conversion of ipv4/ipv6 JSON to QemuOpts Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-01-18Fix corner-case when using VNC+SASL+SPICEChristophe Fergeau
Similarly to the commit 764eb39d1b6 fixing VNC+SASL+QXL, when starting QEMU with SPICE but no SASL, and at the same time VNC with SASL, then spice_server_init() will get called without a previous call to spice_server_set_sasl_appname(), which will cause cyrus-sasl to try to use /etc/sasl2/spice.conf (spice-server uses "spice" as its default appname) rather than the expected /etc/sasl2/qemu.conf. This commit unconditionally calls spice_server_set_sasl_appname() before calling spice_server_init() in order to use the correct appname even if SPICE without SASL was requested on qemu command line.

2016-01-15qemu-char: add logfile facility to all chardev backendsDaniel P. Berrange
Typically a UNIX guest OS will log boot messages to a serial port in addition to any graphical console. An admin user may also wish to use the serial port for an interactive console. A virtualization management system may wish to collect system boot messages by logging the serial port, but also wish to allow admins interactive access. Currently providing such a feature forces the mgmt app to either provide 2 separate serial ports, one for logging boot messages and one for interactive console login, or to proxy all output via a separate service that can multiplex the two needs onto one serial port. While both are valid approaches, they each have their own downsides. The former causes confusion and extra setup work for VM admins creating disk images. The latter places an extra burden to re-implement much of the QEMU chardev backends logic in libvirt or even higher level mgmt apps and adds extra hops in the data transfer path. A simpler approach that is satisfactory for many use cases is to allow the QEMU chardev backends to have a "logfile" property associated with them. $QEMU -chardev socket,host=localhost,port=9000,\ server=on,nowait,id-charserial0,\ logfile=/var/log/libvirt/qemu/test-serial0.log -device isa-serial,chardev=charserial0,id=serial0 This patch introduces a 'ChardevCommon' struct which is setup as a base for all the ChardevBackend types. Ideally this would be registered directly as a base against ChardevBackend, rather than each type, but the QAPI generator doesn't allow that since the ChardevBackend is a non-discriminated union. The ChardevCommon struct provides the optional 'logfile' parameter, as well as 'logappend' which controls whether QEMU truncates or appends (default truncate). Signed-off-by: Daniel P.

2016-01-08ui/curses: Fix color attribute of monitor for cursesOGAWA Hirofumi
Current text_console_update() writes totally broken color attributes to console_write_ch(). The format now is writing, [WRONG] bold << 21 | fg << 12 | bg << 8 | char fg == 3bits curses color number bg == 3bits curses color number I can't see this format is where come from. Anyway, this doesn't work at all. What curses expects is actually (and vga.c is using), [RIGHT] bold << 21 | bg << 11 | fg << 8 | char fg == 3bits vga color number bg == 3bits vga color number And curses set COLOR_PAIR() up to match this format, and curses's chtype. I.e, bold | color_pair | char color_pair == (bg << 3 | fg) To fix, this simply uses VGA color number everywhere except curses.c internal. Then, convert it to above [RIGHT] format to write by console_write_ch(). And as bonus, this reduces to expose curses define to other parts (removes COLOR_* from console.c).

2015-12-17qapi: Change munging of CamelCase enum valuesEric Blake
When munging enum values, the fact that we were passing the entire prefix + value through camel_to_upper() meant that enum values spelled with CamelCase could be turned into CAMEL_CASE. However, this provides a potential collision (both OneTwo and One-Two would munge into ONE_TWO) for enum types, when the same two names are valid side-by-side as QAPI member names. By changing the generation of enum constants to always be prefix + '_' + c_name(value, False).upper(), and ensuring that there are no case collisions (in the next patches), we no longer have to worry about names that would be distinct as QAPI members but collide as variant tag names, without having to think about what munging the heuristics in camel_to_upper() will actually perform on an enum value. Making the change will affect enums that did not follow coding conventions, using 'CamelCase' rather than desired 'lower-case'. Thankfully, there are only two culprits: InputButton and ErrorClass. We already tweaked ErrorClass to make it an alias of QapiErrorClass, where only the alias needs changing rather than the whole tree. So the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN). That part of this commit may later need reverting if we rename the enum constants from 'WheelUp' to 'wheel-up' as part of moving x-input-send-event to a stable interface; but at least we have documentation bread crumbs in place to remind us (commit 513e7cd), and it matches the fact that SDL constants are also spelled SDL_BUTTON_WHEELUP.

2015-12-01ui/cocoa.m: Prevent activation clicks from going to guestPeter Maydell
When QEMU is brought to the foreground, the click event that activates QEMU should not go to the guest. Accidents happen when they do go to the guest without giving the user a chance to handle them. In particular, if the guest input device is not an absolute-position one then the location of the guest cursor (and thus the click) will likely not be the location of the host cursor when it is clicked, and could be completely obscured below another window. Don't send mouse clicks to QEMU unless the window either has focus or has grabbed mouse events.

2015-11-02qapi: Unbox base membersEric Blake
Rather than storing a base class as a pointer to a box, just store the fields of that base class in the same order, so that a child struct can be directly cast to its parent. This gives less malloc overhead, less pointer dereferencing, and even less generated code. Compare to the earlier commit 1e6c1616a "qapi: Generate a nicer struct for flat unions" (although that patch had fewer places to change, as less of qemu was directly using qapi structs for flat unions). It also allows us to turn on automatic type-safe wrappers for upcasting to the base class of a struct. Changes to the generated code look like this in qapi-types.h: | struct SpiceChannel { |- SpiceBasicInfo *base; |+ /* Members inherited from SpiceBasicInfo: */ |+ char *host; |+ char *port; |+ NetworkAddressFamily family; |+ /* Own members: */ | int64_t connection_id; as well as additional upcast functions like qapi_SpiceChannel_base(). Meanwhile, changes to qapi-visit.c look like: | static void visit_type_SpiceChannel_fields(Visitor *v, SpiceChannel **obj, Error **errp) | { | Error *err = NULL; | |- visit_type_implicit_SpiceBasicInfo(v, &(*obj)->base, &err); |+ visit_type_SpiceBasicInfo_fields(v, (SpiceBasicInfo **)obj, &err); | if (err) { (the cast is necessary, since our upcast wrappers only deal with a single pointer, not pointer-to-pointer); plus the wholesale elimination of some now-unused visit_type_implicit_FOO() functions. Without boxing, the corner case of one empty struct having another empty struct as its base type now requires inserting a dummy member (previously, the 'Base *base' member sufficed). And now that we no longer consume a 'base' member in the generated C struct, we can delete the former negative struct-base-clash-base test.

2015-11-02vnc: Hoist allocation of VncBasicInfo to callersEric Blake
A future qapi patch will rework generated structs with a base class to be unboxed. In preparation for that, change the code that allocates then populates an info struct to instead merely populate the fields of an info field passed in as a parameter (renaming vnc_basic_info_get* to vnc_init_basic_info*). Add rudimentary Error handling at the lowest levels for cases where the old code returned NULL; but rather than plumb Error all the way through the stack, the callers drop the error and return NULL as before.

2015-10-14qemu-char: add create to register_char_driverPaolo Bonzini
Having creation as a member of the CharDriver struct removes the need to export functions for qemu-char.c's usage. After the conversion, chardev backends implemented outside qemu-char.c will not need a stub creation function anymore. Ultimately all drivers will be converted. For now, support the case where cd->create == NULL. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
