* qmp: Wean off qerror_report()Markus Armbruster2015-06-221-18/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The traditional QMP command handler interface int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data); doesn't provide for returning an Error object. Instead, the handler is expected to stash it in the monitor with qerror_report(). When we rebased QMP on top of QAPI, we didn't change this interface. Instead, commit 776574d introduced "middle mode" as a temporary aid for converting existing QMP commands to QAPI one by one. More than three years later, we're still using it. Middle mode has two effects: * Instead of the native input marshallers static void qmp_marshal_input_FOO(QDict *, QObject **, Error **) it generates input marshallers conforming to the traditional QMP command handler interface. * It suppresses generation of code to register them with qmp_register_command() This permits giving them internal linkage. As long as we need qmp-commands.hx, we can't use the registry behind qmp_register_command(), so the latter has to stay for now. The former has to go to get rid of qerror_report(). Changing all QMP commands to fit the QAPI mold in one go was impractical back when we started, but by now there are just a few stragglers left: do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(), qmp_netdev_add(), do_device_add(). Switch middle mode to generate native input marshallers, and adapt the stragglers. Simplifies both the monitor code and the stragglers. Rename do_qmp_capabilities() to qmp_capabilities(), and do_device_add() to qmp_device_add, because that's how QMP command handlers are named today.

* qerror: Clean up QERR_ macros to expand into a single stringMarkus Armbruster2015-06-221-33/+33
| | | | | | | | | | | | | | | | | | | | | These macros expand into error class enumeration constant, comma, string. Unclean. Has been that way since commit 13f59ae. The error class is always ERROR_CLASS_GENERIC_ERROR since the previous commit. Clean up as follows: * Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and delete it from the QERR_ macro. No change after preprocessing. * Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into error_setg(...). Again, no change after preprocessing.

* QemuOpts: Wean off qerror_report_err()Markus Armbruster2015-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func(). Propagate errors through it. Since I'm touching it anyway, rename it to vnc_parse().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The asynchronous monitor command interface goes back to commit 940cc30 (Jan 2010). Added a third case to command execution. The hope back then according to the commit message was that all commands get converted to the asynchronous interface, killing off the other two cases. Didn't happen. The initial asynchronous commands balloon and info balloon were converted back to synchronous long ago (commit 96637bc and d72f32), with commit messages calling the asynchronous interface "not fully working" and "deprecated". The only other user went away in commit 3b5704b. New code generally uses synchronous commands and asynchronous events. What exactly is still "not fully working" with asynchronous commands? Well, here's a bug that defeats actual asynchronous use pretty reliably: the reply's ID is wrong (and has always been wrong) unless you use the command synchronously! To reproduce, we need an asynchronous command, so we have to go back before commit 3b5704b. Run QEMU with spice: $ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio {"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} Connect a spice client in another terminal: $ remote-viewer spice://localhost:5900 Set up a migration destination dummy in a third terminal: $ socat TCP-LISTEN:12345 STDIO Now paste the following into the QMP monitor: { "execute": "qmp_capabilities", "id": "i0" } { "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } } { "execute": "query-kvm", "id": "i2" } Produces two replies immediately, one to qmp_capabilities, and one to query-kvm: {"return": {}, "id": "i0"} {"return": {"enabled": false, "present": true}, "id": "i2"} Both are correct. Two lines of debug output from libspice-server not shown. Now EOF socat's standard input to make it close the connection. This makes the asynchronous client_migrate_info complete. It replies: {"return": {}} Bug: "id": "i1" is missing. Two lines of debug output from libspice-server not shown. Cherry on top: storage for the missing ID is leaked. Get rid of this stuff before somebody hurts himself with it.

So we should check this value before using it, otherwise this may cause unexpected memory access.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Live migration with spice works like this today: (1) client_migrate_info monitor cmd (2) spice server notifies client, client connects to target host. (3) qemu waits until spice client connect is finished. (4) send over vmstate (i.e. main part of live migration). (5) spice handover to target host. (3) is implemented by making client_migrate_info a async monitor command. This is the only async monitor command we have. The original reason to implement this dance was that qemu did not accept new tcp connections while the incoming migration was running, so (2) and (4) could not be done in parallel. That issue was fixed long ago though. Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp connects while the incoming migration runs. Time to drop step (3). This patch does exactly that, by making the monitor command synchronous and removing the code needed to handle the async monitor command in ui/spice-core.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

If we're in QMP context, call qerror_report_err() and fail 3. Start reading the key in the monitor. This is two things too many. Inline 1. and 2. into its callers monitor_read_block_device_key() and usb_msd_realize_storage(). Since monitor_read_block_device_key() only ever runs in HMP context, drop 2. there.
