2014-10-04qapi: Add corrupt field to ImageInfoSpecificQCow2Max Reitz6-12/+28
Just like lazy-refcounts, this field will be present iff the qcow2 compat level is 1.1 (or probably any future revision). As expected, this breaks some tests due to the new field present in qemu-img info output; so fix their output accordingly.

2014-10-04iotests: Use _img_infoMax Reitz6-68/+26
qemu-img info should only be used directly if the format-specific information or the name of the format is relevant (some tests explicitly test format-specific information; test 082 uses qcow2-specific settings to test the qemu-img interface); otherwise, tests should always use _img_info instead. Test 082 was touched only partially. It does test the qemu-img interface; however, its invocations of qemu-img info are not real tests but rather verifications, so if format-specific information is not important for the test, there is no reason not to use _img_info. In contrast to directly invoking qemu-img info, "qcow2" is replaced by "IMGFMT"; but as "qcow2" is only mentioned once in test 082 (in _supported_fmt), I consider this an improvement.

2014-10-03util: Emancipate id_wellformed() from QemuOptsMarkus Armbruster6-24/+35
IDs have long spread beyond QemuOpts: not everything with an ID necessarily goes through QemuOpts. Commit 9aebf3b is about such a case: block layer names are meant to be well-formed IDs, but some of them don't go through QemuOpts, and thus weren't checked. The commit fixed that the straightforward way: rename the internal QemuOpts helper id_wellformed() to qemu_opts_id_wellformed() and give it external linkage. Instead of using it directly in block.c, the commit adds wrapper bdrv_is_valid_name(), probably to hide the connection to QemuOpts. Go one logical step further: emancipate IDs from QemuOpts. Rename the function back to id_wellformed(), and put it in another file. While there, clean up its value to bool. Peel off the bdrv_is_valid_name() wrapper. [Replaced stray return 0 with return false to match bool returns used elsewhere in id_wellformed(). --Stefan] Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2014-10-03qtest/bios-tables: Correct Q35 command lineJohn Snow1-6/+4
If the Q35 board types are to begin recognizing and decoding syntactic sugar for drive/device declarations, then workarounds found within the qtests suite need to be adjusted to prevent any test failures after the fix. bios-tables-test improperly uses this cli: -drive file=etc,id=hd -device ide-hd,drive=hd Which will create a drive and device due to the lack of specifying if=none. Then, it will attempt to create a second device and fail. This patch corrects this test to always use the full, non-sugared -device/-drive syntax for both PC and Q35.

2014-10-03ide: Update ide_drive_get to be HBA agnosticJohn Snow12-14/+44
Instead of duplicating the logic for the if_ide (bus,unit) mappings, rely on the blockdev layer for managing those mappings for us, and use the drive_get_by_index call instead. This allows ide_drive_get to work for AHCI HBAs as well, and can be used in the Q35 initialization. Lastly, change the nature of the argument to ide_drive_get so that represents the number of total drives we can support, and not the total number of buses. This will prevent array overflows if the units-per-default-bus property ever needs to be adjusted for compatibility reasons.

2014-10-03pc/vl: Add units-per-default-bus propertyJohn Snow4-1/+13
This patch adds the 'units_per_default_bus' property which allows individual boards to declare their desired index => (bus,unit) mapping for their default HBA, so that boards such as Q35 can specify that its default if_ide HBA, AHCI, only accepts one unit per bus. This property only overrides the mapping for drives matching the block_default_type interface. This patch also adds this property to *all* past and present Q35 machine types. This retroactive addition is justified because the previous erroneous index=>(bus,unit) mappings caused by lack of such a property were not utilized due to lack of initialization code in the Q35 init routine. Further, semantically, the Q35 board type has always had the property that its default HBA, AHCI, only accepts one unit per bus. The new code added to add devices to drives relies upon the accuracy of this mapping. Thus, the property is applied retroactively to reduce complexity of allowing IDE HBAs with different units per bus. Examples: Prior to this patch, all IDE HBAs were assumed to use 2 units per bus (Master, Slave). When using Q35 and AHCI, however, we only allow one unit per bus. -hdb foo.qcow2 would become index=1, or bus=0,unit=1. -hdd foo.qcow2 would become index=3, or bus=1,unit=1. -drive file=foo.qcow2,index=5 becomes bus=2,unit=1. These are invalid for AHCI. They now become, under Q35 only: -hdb foo.qcow2 --> index=1, bus=1, unit=0. -hdd foo.qcow2 --> index=3, bus=3, unit=0. -drive file=foo.qcow2,index=5 --> bus=5,unit=0. The mapping is adjusted based on the fact that the default IF for the Q35 machine type is IF_IDE, and units-per-default-bus overrides the IDE mapping from its default of 2 units per bus to just 1 unit per bus.

2014-10-03blockdev: Allow overriding if_max_dev propertyJohn Snow2-1/+27
The if_max_devs table as in the past been an immutable default that controls the mapping of index => (bus,unit) for all boards and all HBAs for each interface type. Since adding this mapping information to the HBA device itself is currently unwieldly from the perspective of retrieving this information at option parsing time (e.g, within drive_new), we consider the alternative of marking the if_max_devs table mutable so that later configuration and initialization can adjust the mapping at will, but only up until a drive is added, at which point the mapping is finalized.

2014-10-03blockdev: Orphaned drive searchJohn Snow3-1/+32
When users use command line options like -hda, -cdrom, or even -drive if=ide, it is up to the board initialization routines to pick up these drives and create backing devices for them. Some boards, like Q35, have not been doing this. However, there is no warning explaining why certain drive specifications are just silently ignored, so this function adds a check to print some warnings to assist users in debugging these sorts of issues in the future. This patch will not warn about drives added with if_none, for which it is not possible to tell in advance if the omission of a backing device is an issue. A warning in these cases is considered appropriate.

2014-10-03qemu-iotests: Fix supported cache modes for 052Kevin Wolf1-2/+3
The requirement for this test case is really "no O_DIRECT", because the temporary snapshot for BDRV_O_SNAPSHOT is created in /tmp, which often is a tmpfs. Commit f210a83c ('qemu-iotests: Add _default_cache_mode and _supported_cache_modes') turned the restriction into writethrough-only, but that's not really necessary. Allow to run the test for any non-O_DIRECT cache modes, and use the global default of writeback if no cache mode is specified.

2014-10-03make check-block: Use default cache modesKevin Wolf1-1/+1
When qemu-iotests only gave a choice between cache=none and cache=writethrough, we picked cache=none because it was the option that would complete the test in finite time. Some tests could only work for one of the two options and would be skipped with cache=none, but that was an acceptable trade-off at the time. Today, however, qemu-iotests is a bit more flexible than that and you can specify any of the cache modes supported by qemu. The default is writeback, like in qemu, which is fast and (unlike cache=none) compatible with any host filesystem. Test cases that have specific requirements for the cache mode can also specify a different default. In order to get a fast test run that works everywhere and doesn't skip tests that need a different cache mode, not specifying any cache mode and instead relying on the default is the best we can do today.

2014-09-30scsi: Introduce scsi_req_cancel_asyncFam Zheng2-0/+29
Devices will call this function to start an asynchronous cancellation. The bus->info->cancel will be called after the request is canceled. Devices will probably need to track a separate TMF request that triggers this cancellation, and wait until the cancellation is done before completing it. So we store a notifier list in SCSIRequest and in scsi_req_cancel_complete we notify them. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi: Introduce scsi_req_cancel_completeFam Zheng4-4/+20
Let the aio cb do the clean up and notification job after scsi_req_cancel, in preparation for asynchronous cancellation. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi: Drop SCSIReqOps.cancel_ioFam Zheng4-30/+2
The only two implementations are identical to each other, with nothing specific to device: they only call bdrv_aio_cancel with the SCSIRequest.aiocb. Let's move it to scsi-bus. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi: Unify request unref in scsi_req_cancelFam Zheng2-40/+10
Before, scsi_req_cancel will take ownership of the canceled request and unref it. We did this because we didn't know whether AIO CB will be called or not during the cancelling, so we set the io_canceled flag before calling it, and skip unref in the potentially called callbacks, which is not very nice. Now, bdrv_aio_cancel has a stricter contract that the completion callbacks are always called, so we can remove the checks of req->io_canceled and just unref it in callbacks. It will also make implementing asynchronous cancellation easier. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi-generic: Handle canceled request in scsi_command_completeFam Zheng1-4/+6
Now that we always called the cb in bdrv_aio_cancel, let's make scsi-generic callbacks check io_canceled flag similarly to scsi-disk. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi: Drop scsi_req_abortFam Zheng3-19/+10
The only user of this function is spapr_vscsi.c. We can convert to scsi_req_cancel plus adding a check in vscsi_request_cancelled.
