2015-04-28bt-sdp: fix broken uuids power-of-2 calculationStefan Hajnoczi1-1/+1
The binary search in sdp_uuid_match() only works when the number of elements to search is a power of two. lo = record->uuid; hi = record->uuids; while (hi >>= 1) if (lo[hi] <= val) lo += hi; return *lo == val; I noticed that the record->uuids calculation in sdp_service_record_build() was suspect: record->uuids = 1 << ffs(record->uuids - 1); Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)! Actually ffs() is the wrong function to use for power-of-2. Use pow2ceil() to achieve the correct effect. Now the record->uuid[] array is sized correctly and the binary search in sdp_uuid_match() should work. I'm not sure how to run/test this code.

2015-04-28savevm: create snapshot failed when id_str already existsYi Wang1-4/+2
The command "virsh create" will fail in such condition: vm has two disks: vda and vdb. vda has snapshot s1 with id "1", vdb doesn't have s1 but has snapshot s2 with id "1". When we want to run command "virsh create s1", del_existing_snapshots() only deletes s1 in vda, and bdrv_snapshot_create() tries to create vdb's snapshot s1 with id "1", but id "1" alreay exists in vdb with name "s2"! The simplest way is call find_new_snapshot_id() unconditionally.

2015-04-27monitor: Make client_migrate_info synchronousMarkus Armbruster5-33/+11
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. Although the documentation for QMP calls out capabilities negotiation, we should also make it clear in our error messages what we were expecting. With this patch, I now get the following transcript: $ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults {"QMP": {"version": {"qemu": {"micro": 93, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} {"execute":"huh"} {"error": {"class": "CommandNotFound", "desc": "The command huh has not been found"}} {"execute":"quit"} {"error": {"class": "CommandNotFound", "desc": "Expecting capabilities negotiation with 'qmp_capabilities' before command 'quit'"}} {"execute":"qmp_capabilities"} {"return": {}} {"execute":"qmp_capabilities"} {"error": {"class": "CommandNotFound", "desc": "Capabilities negotiation is already complete, command 'qmp_capabilities' ignored"}} {"execute":"quit"} {"return": {}} {"timestamp": {"seconds": 1429110729, "microseconds": 181935}, "event": "SHUTDOWN"} Signed-off-by: Eric Blake <eblake@redhat.com> Tested-By: Kashyap Chamarthy <kchamart@redhat.com> Reviewed-by: Paulo Vital <paulo.vital@profitbricks.com> Reviewed-by: John Snow <jsnow@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2015-04-24qmp-commands: fix incorrect uses of ":O" specifierPaolo Bonzini1-2/+2
As far as the QMP parser is concerned, neither the 'O' nor the 'q' format specifiers put any constraint on the command. However, there are two differences: 1) from a documentation point of view 'O' says that this command takes a dictionary. The dictionary will be converted to QemuOpts in the handler to match the corresponding HMP command. 2) 'O' sets QMP_ACCEPT_UNKNOWNS, resulting in the command accepting invalid extra arguments. For example the following is accepted: { "execute": "send-key", "arguments": { "keys": [ { "type": "qcode", "data": "ctrl" }, { "type": "qcode", "data": "alt" }, { "type": "qcode", "data": "delete" } ], "foo": "bar" } } Neither send-key nor migrate-set-capabilities take a QemuOpts-like dictionary; they take an array of dictionaries. And neither command really wants to have extra unknown arguments. Thus, the right specifier to use in this case is 'q'; with this patch the above command fails with {"error": {"class": "GenericError", "desc": "Invalid parameter 'foo'"}} as intended.

2015-04-24qapi: Drop dead genlist parameterEric Blake1-13/+9
Defaulting a parameter to True, then having all callers omit or pass an explicit True for that parameter, is pointless.
