2009-07-16replace bdrv_{get, put}_buffer with bdrv_{load, save}_vmstateChristoph Hellwig1-6/+8
The VM state offset is a concept internal to the image format. Replace the old bdrv_{get,put}_buffer method that require an index into the image file that is constructed from the VM state offset and an offset into the vmstate with the bdrv_{load,save}_vmstate that just take an offset into the VM state.

Commit 6a7ad299 ("Call qemu_bh_delete at bdrv_aio_bh_cb") deletes emulated aio bottom halves to prevent endless accumulation. However, it leaves a stale ->bh pointer, which is then waited on when the aio is reused. Zeroing the pointer fixes the issue, allowing vmdk format images to be used.

2009-06-29support colon in filenamesRam Pai1-10/+17
Problem: It is impossible to feed filenames with the character colon because qemu interprets such names as a protocol. For example filename scsi:0, is interpreted as a protocol by name "scsi". This patch allows user to espace colon characters. For example the above filename can now be expressed either as 'scsi\:0' or as file:scsi:0 anything following the "file:" tag is interpreted verbatin. However if "file:" tag is omitted then any colon characters in the string must be escaped using backslash. Here are couple of examples: scsi\:0\:abc is a local file scsi:0:abc http\://myweb is a local file by name http://myweb file:scsi:0:abc is a local file scsi:0:abc file:http://myweb is a local file by name http://myweb Signed-off-by: Ram Pai <linuxram@us.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-16Prevent CD-ROM media eject while device is lockedMark McLoughlin1-1/+8
Section 10.8.25 ("START/STOP UNIT Command") of SFF-8020i states that if the device is locked we should refuse to eject if the device is locked. ASC_MEDIA_REMOVAL_PREVENTED is the appropriate return in this case. In order to stop itself from ejecting the media it is running from, Fedora's installer (anaconda) requires the CDROMEJECT ioctl() to fail if the drive has been previously locked.

Add a bdrv_probe_device method to all BlockDriver instances implementing host devices to move matching of host device types into the actual drivers.

Instead of declaring one BlockDriver for all host devices declared one for each type: a generic one for normal disk devices, a Linux floppy driver and a CDROM driver for Linux and FreeBSD. This gets rid of a lot of messy ifdefs and switching based on the type in the various removal device methods. block.c grows a new method to find the correct host device driver based on OS-sepcific criteria, which will later into the actual drivers in a later patch in this series.

2009-05-27fully split aio_pool from BlockDriverChristoph Hellwig1-40/+25
Now that we have a separate aio pool structure we can remove those aio pool details from BlockDriver. Every driver supporting AIO now needs to declare a static AIOPool with the aiocb size and the cancellation method. This cleans up the current code considerably and will make it cleaner and more obvious to support two different aio implementations behind a single BlockDriver.

2009-04-22implement qemu_blockalign (Stefano Stabellini)aliguori1-1/+8
this patch adds a buffer_alignment field to BlockDriverState and implements a qemu_blockalign function that uses that field to allocate a memory aligned buffer to be used by the block driver. buffer_alignment is initialized to 512 but each block driver can set a different value (at the moment none of them do). This patch modifies ide.c, block-qcow.c, block-qcow2.c and block.c to use qemu_blockalign instead of qemu_memalign. There is only one place left that still uses qemu_memalign to allocate buffers used by block drivers that is posix-aio-compat:handle_aiocb_rw because it is not possible to get the BlockDriverState from that function. However I think it is not important because posix-aio-compat already deals with driver specific code so it is supposed to know its own needs.

2009-03-28new scsi-generic abstraction, use SG_IO (Christoph Hellwig)aliguori1-18/+7
Okay, I started looking into how to handle scsi-generic I/O in the new world order. I think the best is to use the SG_IO ioctl instead of the read/write interface as that allows us to support scsi passthrough on disk/cdrom devices, too. See Hannes patch on the kvm list from August for an example. Now that we always do ioctls we don't need another abstraction than bdrv_ioctl for the synchronous requests for now, and for asynchronous requests I've added a aio_ioctl abstraction keeping it simple. Long-term we might want to move the ops to a higher-level abstraction and let the low-level code fill out the request header, but I'm lazy enough to leave that to the people trying to support scsi-passthrough on a non-Linux OS. Tested lightly by issuing various sg_ commands from sg3-utils in a guest to a host CDROM device.

2009-03-12Add specialized block driver scsi generic API (Avi Kivity)aliguori1-0/+22
When a scsi device is backed by a scsi generic device instead of an ordinary host block device, the block API is abused in a couple of annoying ways: - nb_sectors is negative, and specifies a byte count instead of a sector count - offset is ignored, since scsi-generic is essentially a packet protocol This overloading makes hacking the block layer difficult. Remove it by introducing a new explicit API for scsi-generic devices. The new API is still backed by the old implementation, but at least the users are insulated.

2009-03-05monitor: Rework API (Jan Kiszka)aliguori1-33/+33
Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.

2009-03-03Fix CVE-2008-0928 - insufficient block device address range checking ↵aliguori1-0/+55
(Anthony Liguori) Introduce a growable flag that's set by bdrv_file_open(). Block devices should never be growable, only files that are being used by block devices. I went through Fabrice's early comments about the patch that was first applied. While I disagree with that patch, I also disagree with Fabrice's suggestion. There's no good reason to do the checks in the block drivers themselves. It just increases the possibility that this bug could show up again. Since we're calling bdrv_getlength() to determine the length, we're giving the block drivers a chance to chime in and let us know what range is valid. Basically, this patch makes the BlockDriver API guarantee that all requests are within 0..bdrv_getlength() which to me seems like a Good Thing. What do others think?
