* blktap: cleanupKeir Fraser2008-07-112-4/+3

* Blktapctrl compatibility layerKeir Fraser2008-07-091-1/+7
| | | | | | | | | | | I originally had just changed the NEWINTF ioctl to send over 48-bits of information, which works on 64-bit but not on 32-bit (since the arg is an unsigned long). Additionally, the previous changes would break an older userland against a new kernel. For that reason, introduce a new ioctl (NEWINTF_EXT) that fixes both of these problems. This is the dom0 userland side. Signed-off-by: Chris Lalancette <clalance@redhat.com>

* Use ioemu block drivers through blktap.Keir Fraser2008-03-181-10/+0
| | | | | | | | | | Add support for a tap:ioemu pseudo driver. Devices using this driver won't use tapdisk (containing the code duplication) any more, but will connect to the qemu-dm of the domain. In this way no working configuration should be broken right now as you can still choose to use the tapdisk drivers. Signed-off-by: Kevin Wolf <kwolf@suse.de>

* Revert 16560:822d4ec5cfb1.Keir Fraser2007-12-081-2/+2
| | | | | | | | | | | | | Preference seems to be to update library versions only when the ABI changes. Only libxenctrl/libxenguest have their version number changed to 3.2.0, as a reminder that they change on pretty much every major release. libfsimage/libxenstore/libblktap have not changed substantially recently, hence the ABI has not changed, and version number stays the same as in Xen 3.1 (and before).

* tools: Rationalise library soname versions.Keir Fraser2007-12-071-2/+2
| | | | | | | | | | | | | | | | * Arrange for the sonames of libxenstore, libxc, libfsimage and libblktap to be set from a single place in Config.mk. * Bumps the soname major version number to 3.2 in preparation for 3.2 rc1 after which we do not expect to have ABI changes. I have not done anything about libaio and libflask. The former is imported from elsewhere and if we're lucky will have sane versioning upstream. libflask has a very small interface and I'm hoping that the XSM authors have been keeping some ABI discipline.

| | | | | | | | | | Attached patch removes unused linux specific headers and makes bswap.h ready for BSD support. This is first step for BSD support in blktap. More to come. No functional change. Signed-off-by: Christoph Egger <Christoph.Egger@amd.com>

* tools: warn_unused_result build fixes.kfraser@localhost.localdomain2007-06-122-27/+24
| | | | | | | | | | | | Note that some of the existing error checking for asprintf was wrong for Linux. asprintf in glibc returns -1 on error, but leaves the pointer uninitialized. Only the BSDs zero out the pointer on error. Also, while fixing these warnings I saw several error paths that were incorrect. This patch minimally fixes the warn_unused_result; more complete error path cleanup will be a later patch. Signed-off-by: Charles Coffing <ccoffing@novell.com>

* [TAPDISK] add tapdisk support for image chainingJake Wires2007-02-162-7/+14
| | | | | | | | Enables tapdisk to chain an arbitrary number of VDIs, propagating reads of holes in children to their parent images. Introduces two new functions to the tapdisk interface to facilitate this. Modifies the QCoW plugin to take advantage of these changes, thus providing support for arbitrarily long chains of QCoW image types.
* [BLKTAP] Use lartge enough types to express parameters of large block devices.kfraser@localhost.localdomain2006-11-282-7/+7
| | | | | | | | | | | | | | | | | | | | While the kernel side of blktap drivers is using 64-bit sector numbers correctly when reporting disk sizing, the userspace parts where this dat is actually generated is truncating at 32-bit. There are 3 variables related to disk sizing which are used in the kernel/userspace code 'size', 'sector size' & 'info'. In kernel space these are treated as being unsigned long long, unsigned long, and unsigned int, respectively. In the blktap userspace code this were all varyingly long, unsigned long. This mismatch caused 32-bit wraparound on large disks. The attached patch updates the blktap userspace to use the same data types as kernel space for all these params, thus both fixing the 32-bit bug & giving the code consistency. This patch has been tested both by comparing /proc/partitions in the guest, with the image size seen in the host, and by using Stephen Tweedie's 'verify-data' tool on a variety of multi-TB sized disks.

* [BLKTAP] have blktap use a dynamic majorAndrew Warfield2006-09-281-1/+2
| | | | | | | | | | | | blktap currently uses a hardcoded major of 254 for the device. This is not robust in anyway and needs to be dynamic. Note: it is better not to have the daemon create the node, and have udev create it instead. But since the daemon currently creates the node anyway, it is still the way this is done. That change needs to be made at another time. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
