2016-04-20mirror: Don't extend the last sub-chunkFam Zheng
The last sub-chunk is rounded up to the copy granularity in the target image, resulting in a larger size than the source. Add a function to clip the copied sectors to the end. This undoes the "wrong" changes to tests/qemu-iotests/109.out in e5b43573e28. The remaining two offset changes are okay.

2016-04-15block: Fix blk_aio_write_zeroes()Kevin Wolf
Commit 57d6a428 broke blk_aio_write_zeroes() because in some write functions in the call path don't have an explicit length argument but reuse qiov->size instead. Which is great, except that write_zeroes doesn't have a qiov, which this commit interprets as 0 bytes. Consequently, blk_aio_write_zeroes() didn't effectively do anything. This patch introduces an explicit acb->bytes in BlkAioEmAIOCB and uses that instead of acb->rwco.size. The synchronous version of the function is okay because it does pass a qiov (with the right size and a NULL pointer as its base).

2016-04-12qemu-iotests: 148: properly skip test if quorum support is missingSascha Silbe
qemu-iotests test case 148 already had some code for skipping the test if quorum support is missing, but it didn't work in all cases. TestQuorumEvents.setUp() gets run before the actual test class (which contains the skipping code) and tries to start qemu with a drive using the quorum driver. For some reason this works fine when using qcow2, but fails for raw. As the entire test case requires quorum, just check for availability before even starting the test suite. Introduce a verify_quorum() function in iotests.py for this purpose so future test cases can make use of it.

2016-03-30qemu-img: Fix preallocation with -S 0 for convertMax Reitz
When passing -S 0 to qemu-img convert, the target image is supposed to be fully allocated. Right now, this is not the case if the source image contains areas which bdrv_get_block_status() reports as being zero. This patch changes a zeroed area's status from BLK_ZERO to BLK_DATA before invoking convert_write() if -S 0 has been specified. In addition, the check whether convert_read() actually needs to do anything (basically only if the current area is a BLK_DATA area) is pulled out of that function to the caller. If -S 0 has been specified, zeroed areas need to be written as data to the output, thus they then have to be accounted when calculating the progress made. This patch changes the reference output for iotest 122; contrary to what it assumed, -S 0 really should allocate everything in the output, not just areas that are filled with zeros (as opposed to being zeroed).

2016-03-30block: Remove BDRV_O_CACHE_WBKevin Wolf
The previous patches have successively made blk->enable_write_cache the true source for the information whether a writethrough mode must be implemented. The corresponding BDRV_O_CACHE_WB is only useless baggage we're carrying around, so now's the time to remove it. At the same time, we remove the 'cache.writeback' option parsing on the BDS level as the only effect was setting the BDRV_O_CACHE_WB flag. This change requires test cases that explicitly enabled the option to drop it. Other than that and the change of the error message when writethrough is enabled on the BDS level (from "Can't set writethrough mode" to "doesn't support the option"), there should be no change in behaviour.

We must forbid changing the WCE flag in bdrv_reopen() in the same patch, as otherwise the behaviour would change so that the flag takes precedence over the explicitly specified option.

Now that WCE is handled on the BlockBackend level, the flag is meaningless for BDSes. As the schema requires us to fill the field, we return an enabled write cache for them. Note that this means that querying the BlockBackend name may return writethrough as the cache information, whereas querying the node-name of the root of that same BlockBackend will return writeback. This may appear odd at first, but it actually makes sense because it correctly repesents the layer that implements the WCE handling. This becomes more apparent when you consider nodes that are the root node of multiple BlockBackends, where each BB can have its own WCE setting.

It is important that the QEMU luks implementation retains 100% compatibility with the reference implementation provided by the combination of the linux kernel dm-crypt module and cryptsetup userspace tools. There is a matrix of tests to be performed with different sets of encryption settings. For each matrix entry, two tests will be performed. One will create a LUKS image with the cryptsetup tool and then do I/O with both cryptsetup & qemu-io. The other will create the image with qemu-img and then again do I/O with both cryptsetup and qemu-io. The new I/O test 149 performs interoperability testing between QEMU and the reference implementation. Such testing inherantly requires elevated privileges, so to this this the user must have configured passwordless sudo access. The test will automatically skip if sudo is not available.

2016-03-30block: move encryption deprecation warning into qcow codeDaniel P. Berrange
For a couple of releases we have been warning Encrypted images are deprecated Support for them will be removed in a future release. You can use 'qemu-img convert' to convert your image to an unencrypted one. This warning was issued by system emulators, qemu-img, qemu-nbd and qemu-io. Such a broad warning was issued because the original intention was to rip out all the code for dealing with encryption inside the QEMU block layer APIs. The new block encryption framework used for the LUKS driver does not rely on the unloved block layer API for encryption keys, instead using the QOM 'secret' object type. It is thus no longer appropriate to warn about encryption unconditionally. When the qcow/qcow2 drivers are converted to use the new encryption framework too, it will be practical to keep AES-CBC support present for use in qemu-img, qemu-io & qemu-nbd to allow for interoperability with older QEMU versions and liberation of data from existing encrypted qcow2 files. This change moves the warning out of the generic block code and into the qcow/qcow2 drivers. Further, the warning is set to only appear when running the system emulators, since qemu-img, qemu-io, qemu-nbd are expected to support qcow2 encryption long term now that the maint burden has been eliminated.

2016-03-30tests: redirect stderr to stdout for iotestsDaniel P. Berrange
The python I/O tests helper for running qemu-img/qemu-io setup stdout to be captured to a pipe, but left stderr untouched. As a result, if something failed in qemu-img/ qemu-io, data written to stderr would get output directly and not line up with data on the test stdout due to buffering. If we explicitly redirect stderr to the same pipe as stdout, things are much clearer when they go wrong. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-03-30block: Reject writethrough mode except at the rootKevin Wolf
Writethrough mode is going to become a BlockBackend feature rather than a BDS one, so forbid it in places where we won't be able to support it when the code finally matches the envisioned design. We only allowed setting the cache mode of non-root nodes after the 2.5 release, so we're still free to make this change. The target of block jobs is now always opened in a writeback mode because it doesn't have a BlockBackend attached. This makes more sense anyway because block jobs know when to flush. If the graph is modified on job completion, the original cache mode moves to the new root, so for the guest device writethough always stays enabled if it was configured this way.

This test is streaming to the top layer using the intermediate image as the base. This is a mistake since block-stream never copies data from the base image and its backing chain, so this is effectively a no-op. In addition to fixing the base parameter, this patch also writes some data to the intermediate image before the test, so there's something to copy and the test is meaningful.

2016-03-22qemu-log: support simple pid substitution for logsAlex Bennée
When debugging stuff that occurs over several forks it would be useful not to keep overwriting the one logfile you've set-up. This allows a simple %d to be included once in the logfile parameter which is substituted with getpid(). As the test cases involve checking user output they need g_test_trap_subprocess() support. As a result they are currently skipped on Travis builds due to the older glib involved.

2016-03-22qemu-log: new option -dfilter to limit outputAlex Bennée
When debugging big programs or system emulation sometimes you want both the verbosity of cpu,exec et all but don't want to generate lots of logs for unneeded stuff. This patch adds a new option -dfilter which allows you to specify interesting address ranges in the form: -dfilter 0x8000..0x8fff,0xffffffc000080000+0x200,... Then logging code can use the new qemu_log_in_addr_range() function to decide if it will output logging information for the given range.
