2015-04-27monitor: check return value of qemu_find_net_clients_except()Jason Wang1-4/+4
qemu_find_net_clients_except() may return a value which is greater than the size of array we provided. So we should check this value before using it, otherwise this may cause unexpected memory access.

2015-04-27monitor: Make client_migrate_info synchronousMarkus Armbruster1-3/+2
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>

2015-04-24qmp: Give saner messages related to qmp_capabilities misuseEric Blake1-4/+19
Pretending that QMP doesn't understand a command merely because we are not in the right mode doesn't help first-time users figure out what to do to correct things.

2015-03-18profiler: Reenable built-in profilerAlexey Kardashevskiy1-3/+3
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile when configured with --enable-profiler. Turned out the profiler has been broken for a while. This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode. This also fixes the compile error. This changes profile_getclock() to return nanoseconds rather than CPU ticks as the "profile" HMP command prints seconds and there is no platform-independent way to get ticks-per-second rate. Since TCG is quite slow and get_clock() returns nanoseconds (fine enough), this should not affect precision much. This removes unused qemu_time_start and tlb_flush_time.

monitor_read_bdrv_key_start() does several things: 1. If no key is needed, call completion_cb() and succeed 2. 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. The next commit will clean up the result in usb_msd_realize_storage().

The correct functions for this purpose are ld*_p(), which take a host pointer, rather than ld*_raw(), which take an integer representing a guest address and are somewhat meaningless in softmmu configurations.

2014-11-27hmp: fix regression of HMP device_del auto-completionMarcel Apfelbaum1-7/+4
The commits: - 6a1fa9f5 (monitor: add del completion for peripheral device) - 66e56b13 (qdev: add qdev_build_hotpluggable_device_list helper) cause a QEMU crash when trying to use HMP device_del auto-completion. It can be easily reproduced by: <qemu-bin> -enable-kvm ~/images/fedora.qcow2 -monitor stdio -device virtio-net-pci,id=vnet (qemu) device_del /home/mapfelba/git/upstream/qemu/hw/core/qdev.c:941:qdev_build_hotpluggable_device_list: Object 0x7f6ce04e4fe0 is not an instance of type device Aborted (core dumped) The root cause is qdev_build_hotpluggable_device_list going recursively over all peripherals and their children assuming all are devices. It doesn't work since PCI devices have at least on child which is a memory region (bus master). Solved by observing that all devices appear as direct children of /machine/peripheral container. No need of going recursively over all the children.

When do memory hotplug, if there is numa node, we should add the memory size to the corresponding node memory size. It affects the result of hmp command "info numa".

2014-10-24hmp: Remove "info pcmcia"Markus Armbruster1-8/+0
This command lists PCMCIA sockets and cards. Only a few ARM boards have sockets (akita, borzoi, connex, mainstone, spitz, terrier, tosa, verdex, z2), the only card is the DSCM-1xxxx Hitachi Microdrive (qdev "microdrive"), and it is only inserted during machine init, if ever. So this command doesn't really tell anybody anything new so far. Moreover, pcmcia_socket_unregister() has a use-after-free bug, flagged by Coverity. Has never been used, because there has never been code to eject a PCMCIA card. Not worth fixing & converting to QMP. Remove it.

2014-09-26monitor: Reset HMP mon->rs in CHR_EVENT_OPENStratos Psomadakis1-0/+1
Commit cdaa86a54 ("Add G_IO_HUP handler for socket chardev") exposed a bug in the way the HMP monitor handles its command buffer. When a client closes the connection to the monitor, tcp_chr_read() will detect the G_IO_HUP condition and call tcp_chr_disconnect() to close the server-side connection too. Due to the fact that monitor reads 1 byte at a time (for each tcp_chr_read()), the monitor readline state / buffers might contain junk (i.e. a half-finished command). Thus, without calling readline_restart() on mon->rs in CHR_EVENT_OPEN, future HMP commands will fail.
