* monitor/qmp: Stop processing requests when shutdown is requestedKevin Wolf2021-02-151-0/+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.

* monitor: Fix assertion failure on shutdownKevin Wolf2021-02-151-10/+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.

* block: add ability to specify list of blockdevs during snapshotDaniel P. Berrangé2021-02-081-1/+1
| | | | | | | | | | | | | | | | When running snapshot operations, there are various rules for which blockdevs are included/excluded. 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. Thus there needs to be a way for the mgmt app to provide an explicit list of blockdevs to perform snapshots across. This can be achieved by passing a list of node names that should be used.

| | | | | | | | | | | | | | | | | The bdrv_all_*_snapshot functions return a BlockDriverState pointer for the invalid backend, which the callers then use to report an error message.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Reproducer: ---> {'execute': 'query-migrate-parameters'} <--- {"return": {[...] "compress-threads": 8, [...]}} ---> {"execute": "migrate-set-parameters", "arguments": {"compress-threads": 257}} <--- {"return": {}} ---> {'execute': 'query-migrate-parameters'} <--- {"return": {[...] "compress-threads": 1, [...]}} Fix by resynchronizing MigrateSetParameters with MigrationParameters.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* remove preconfig statePaolo Bonzini2020-12-152-6/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mon_get_cpu_env() is indirectly called monitor_parse_arguments() where the current monitor isn't set yet.

* console: make QMP/HMP screendump run in coroutineMarc-André Lureau2020-11-041-1/+2
| | | | | | | | | | | | | | | | | | | Thanks to the monitors' coroutine support (merge commit b7092cda1b3), the screendump handler can trigger a graphic_hw_update(), yield and let the main loop run until update is done. Then the handler is resumed, and ppm_save() will write the screen image to disk in the coroutine context. The IO is still blocking though, as the file is set blocking so far, this could be addressed by some future change (with other caveats).
