2012-02-09iSCSI: add configuration variables for iSCSIRonnie Sahlberg
This patch adds configuration variables for iSCSI to set initiator-name to use when logging in to the target, which type of header-digest to negotiate with the target and username and password for CHAP authentication. This allows specifying a initiator-name either from the command line -iscsi initiator-name=iqn.2004-01.com.example:test or from a configuration file included with -readconfig [iscsi] initiator-name = iqn.2004-01.com.example:test header-digest = CRC32C|CRC32C-NONE|NONE-CRC32C|NONE user = CHAP username password = CHAP password If you use several different targets, you can also configure this on a per target basis by using a group name: [iscsi "iqn.target.name"] ... The configuration file can be read using -readconfig. Example : qemu-system-i386 -drive file=iscsi://127.0.0.1/iqn.ronnie.test/1 -readconfig iscsi.conf Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-02-09qemu-io: add write -z option for bdrv_co_write_zeroesStefan Hajnoczi
Extend the qemu-io write command with the -z option to call bdrv_co_write_zeroes(). Exposing the zero write interface from qemu-io allows us to write tests that exercise this new block layer interface.

2012-02-09qed: add .bdrv_co_write_zeroes() supportStefan Hajnoczi
Zero writes are a dedicated interface for writing regions of zeroes into the image file. If clusters are not yet allocated it is possible to use an efficient metadata representation which keeps the image file compact and does not store individual zero bytes. Implementing this for the QED image format is fairly straightforward. The only issue is that when a zero write touches an existing cluster we have to allocate a bounce buffer and perform a regular write.

2012-02-09qed: replace is_write with flags fieldStefan Hajnoczi
Per-request attributes like read/write are currently implemented as bool fields in the QEDAIOCB struct. This becomes unwiedly as the number of attributes grows. For example, the qed_aio_setup() function would have to take multiple bool arguments and at call sites it would be hard to distinguish the meaning of each bool. Instead use a flags field with bitmask constants. This will be used when zero write support is added.

2012-02-09block: perform zero-detection during copy-on-readStefan Hajnoczi
Copy-on-Read populates the image file with data read from a backing image. In order to avoid bloating the image file when all zeroes are read we should scan the buffer and perform an optimized zero write operation.

2012-02-09block: add .bdrv_co_write_zeroes() interfaceStefan Hajnoczi
The ability to zero regions of an image file is a useful primitive for higher-level features such as image streaming or zero write detection. Image formats may support an optimized metadata representation instead of writing zeroes into the image file. This allows zero writes to be potentially faster than regular write operations and also preserve sparseness of the image file. The .bdrv_co_write_zeroes() interface should be implemented by block drivers that wish to provide efficient zeroing. Note that this operation is different from the discard operation, which may leave the contents of the region indeterminate. That means discarded blocks are not guaranteed to contain zeroes and may contain junk data instead.

2012-02-09cutils: extract buffer_is_zero() from qemu-img.cStefan Hajnoczi
The qemu-img.c:is_not_zero() function checks if a buffer contains all zeroes. This function will come in handy for zero-detection in the block layer, so clean it up and move it to cutils.c. Note that the function now returns true if the buffer is all zeroes. This avoids the double-negatives (i.e. !is_not_zero()) that the old function can cause in callers.

2012-02-09ARM devboards: Set arm_sysctl properties before init, not afterPeter Maydell
The ARM devboard models (vexpress-a9, realview, versatilepb, etc) were accidentally trying to set one of the arm_sysctl properties after device init. This has now become a fatal error; set the property before device init where it should be done instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2012-02-07qdev: allow reusing get/set for legacy propertyPaolo Bonzini
In some cases, a legacy property does need a special print method but not a special parse method. In this case, we can reuse the get/set from the static (non-legacy) property. If neither parse nor print is needed, though, do not register the legacy property at all. The previous patch ensures that the right fallback will be used.

2012-02-07qdev: remove direct calls to print/parsePaolo Bonzini
There's no need to call into ->parse and ->print manually. The QOM legacy properties do that for us. Furthermore, in some cases legacy and static properties have exactly the same behavior, and we could drop the legacy properties right away. Add an appropriate fallback to prepare for this.

2012-02-07qom: use object_resolve_path_type for linksPaolo Bonzini
This allows to restrict partial matches to objects of the expected type. It will let people use bare names to reference drives even though their name might be the same as a device's (e.g. -drive id=hd0,if=none,... -device ...,drive=hd0,id=hd0). As a useful byproduct, this fixes a problem with links of interface type. When a link property's type is an interface, the code expects the implementation object (not the parent object) to be stored in the variable. The parent object does not contain the right vtable.
