2021-03-23qmp: add new qmp display-reloadZihao Chang1-0/+17
This patch provides a new qmp to reload display configuration without restart VM, but only reloading the vnc tls certificates is implemented.

2021-03-19monitor: Drop query-qmp-schema 'gen': false hackMarkus Armbruster3-17/+17
QMP commands return their response as a generated QAPI type, which the monitor core converts to JSON via QObject. query-qmp-schema's response is the generated introspection data. This is a QLitObject since commit 7d0f982bfb "qapi: generate a literal qobject for introspection", v2.12). Before, it was a string. Instead of converting QLitObject / string -> QObject -> QAPI type SchemaInfoList -> QObject -> JSON, we take a shortcut: the command is 'gen': false, so it can return the QObject instead of the QAPI type. Slightly simpler and more efficient. The next commit will filter the response for output policy, and this is easier in the SchemaInfoList representation. Drop the shortcut. This replaces the manual command registration by a generated one. The manual registration makes the command available before the machine is built by passing flag QCO_ALLOW_PRECONFIG. To keep it available there, we need need to add 'allow-preconfig': true to its definition in the schema.

2021-03-19hmp: QAPIfy object_addKevin Wolf1-15/+2
This switches the HMP command object_add from a QemuOpts-based parser to user_creatable_add_from_str() which uses a keyval parser and enforces the QAPI schema. Apart from being a cleanup, this makes non-scalar properties and help accessible. In order for help to be printed to the monitor instead of stdout, the printf() calls in the help functions are changed to qemu_printf().

2021-03-19qapi/qom: QAPIfy object-addKevin Wolf1-2/+0
This converts object-add from 'gen': false to the ObjectOptions QAPI type. As an immediate benefit, clients can now use QAPI schema introspection for user creatable QOM objects. It is also the first step towards making the QAPI schema the only external interface for the creation of user creatable objects. Once all other places (HMP and command lines of the system emulator and all tools) go through QAPI, too, some object implementations can be simplified because some checks (e.g. that mandatory options are set) are already performed by QAPI, and in another step, QOM boilerplate code could be generated from the schema.

The generic 'migrate_set_parameters' command handle all types of param. Only the QMP commands were documented in the deprecations page, but the rationale for deprecating applies equally to HMP, and the replacements exist. Furthermore the HMP commands are just shims to the QMP commands, so removing the latter breaks the former unless they get re-implemented.

2021-02-15monitor/qmp: Stop processing requests when shutdown is requestedKevin Wolf1-0/+5
Before this patch, monitor_qmp_dispatcher_co() used to check whether shutdown is requested only when it would have to wait for new requests. If there were still some queued requests, it would try to execute all of them before shutting down. This can be surprising when the queued QMP commands take long or hang because Ctrl-C may not actually exit QEMU as soon as possible. Change monitor_qmp_dispatcher_co() so that it additionally checks whether shutdown is request before it gets a new request from the queue.

2021-02-15monitor: Fix assertion failure on shutdownKevin Wolf1-10/+15
Commit 357bda95 already tried to fix the order in monitor_cleanup() by moving shutdown of the dispatcher coroutine further to the start. However, it didn't go far enough: iothread_stop() makes sure that all pending work (bottom halves) in the AioContext of the monitor iothread is completed. iothread_destroy() depends on this and fails an assertion if there is still a pending BH. While the dispatcher coroutine is running, it will try to resume the monitor after taking a request out of the queue, which involves a BH. The dispatcher is run until it terminates in the AIO_WAIT_WHILE() loop. However, adding new BHs between iothread_stop() and iothread_destroy() is forbidden. Fix this by stopping the dispatcher first before shutting down the other parts of the monitor. This means we can now receive requests that aren't handled any more when QEMU is shutting down, but this is unlikely to be a problem for QMP clients.

While this provides reasonable default behaviour, there are scenarios that are not well handled by the default logic. Some of the conditions do not have a single correct answer.

Commit 741d4086c8 "migration: Use proper types in json" (v2.12.0) switched MigrationParameters to narrower integer types, and removed the simplified qmp_migrate_set_parameters()'s argument checking accordingly. Good idea, except qmp_migrate_set_parameters() takes MigrateSetParameters, not MigrationParameters. Its job is updating migrate_get_current()->parameters (which *is* of type MigrationParameters) according to its argument. The integers now get truncated silently.

2021-01-23hmp: remove "change vnc TARGET" commandPaolo Bonzini1-2/+5
The HMP command \"change vnc TARGET\" is messy: - it takes an ugly shortcut to determine if the option has an "id", with incorrect results if "id=" is not preceded by an unescaped comma. - it deletes the existing QemuOpts and does not try to rollback if the parsing fails (which is not causing problems, but only due to how VNC options are parsed) - because it uses the same parsing function as "-vnc", it forces the latter to not support "-vnc help". On top of this, it uses a deprecated QMP command, thus getting in the way of removing the QMP command. Since the usecase for the command is not clear, just remove it and send "change vnc password" directly to the QMP "change-vnc-password" command.

2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake3-27/+21
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-12-15qmp: generalize watchdog-set-action to -no-reboot/-no-shutdownAlejandro Jimenez1-1/+2
Add a QMP command to allow for the behaviors specified by the -no-reboot and -no-shutdown command line option to be set at runtime. The new command is named set-action and takes optional arguments, named after an event, that provide a corresponding action to take. Example: -> { "execute": "set-action", "arguments": { "reboot": "none", "shutdown": "poweroff", "watchdog": "debug" } } <- { "return": {} } Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Alejandro Jimenez <alejandro.j.jimenez@oracle.com> Message-Id: <1607705564-26264-4-git-send-email-alejandro.j.jimenez@oracle.com> [Split the series differently, with -action based on the QMP command. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2020-12-15vl: remove separate preconfig main_loopPaolo Bonzini1-9/+0
Move post-preconfig initialization to the x-exit-preconfig. If preconfig is not requested, just exit preconfig mode immediately with the QMP command. As a result, the preconfig loop will run with accel_setup_post and os_setup_post restrictions (xen_restrict, chroot, etc.) already done.

2020-12-15remove preconfig statePaolo Bonzini2-6/+6
The preconfig state is only used if -incoming is not specified, which makes the RunState state machine more tricky than it need be. However there is already an equivalent condition which works even with -incoming, namely qdev_hotplug. Use it instead of a separate runstate.

AMD SEV allows a guest owner to inject a secret blob into the memory of a virtual machine. The secret is encrypted with the SEV Transport Encryption Key and integrity is guaranteed with the Transport Integrity Key. Although QEMU facilitates the injection of the launch secret, it cannot access the secret.
