2017-11-14qcow2: Add iotest for an empty refcount tableAlberto Garcia
This patch adds a simple iotest in which we try to write to an image with an empty refcount table (i.e. with all entries set to 0). This scenario was already handled by the existing consistency checks, but we add an explicit test case for completeness.

2017-11-14qcow2: Don't open images with header.refcount_table_clusters == 0Alberto Garcia
qcow2_do_open() is checking that header.refcount_table_clusters is not too large, but it doesn't check that it's greater than zero. Apart from the fact that an image like that is obviously corrupted, trying to use it crashes QEMU since we end up with a null s->refcount_table after qcow2_refcount_init(). These images can however be repaired, so allow opening them if the BDRV_O_CHECK flag is set.

2017-11-14qcow2: Prevent allocating refcount blocks at offset 0Alberto Garcia
Each entry in the qcow2 cache contains an offset field indicating the location of the data in the qcow2 image. If the offset is 0 then it means that the entry contains no data and is available to be used when needed. Because of that it is not possible to store in the cache the first cluster of the qcow2 image (offset = 0). This is not a problem because that cluster always contains the qcow2 header and we're not using this cache for that. However, if the qcow2 image is corrupted it can happen that we try to allocate a new refcount block at offset 0, triggering this assertion and crashing QEMU: qcow2_cache_entry_mark_dirty: Assertion `c->entries[i].offset != 0' failed This patch adds an explicit check for this scenario and a new test case.

2017-11-09nbd-client: Refuse read-only client with BDRV_O_RDWREric Blake
The NBD spec says that clients should not try to write/trim to an export advertised as read-only by the server. But we failed to check that, and would allow the block layer to use NBD with BDRV_O_RDWR even when the server is read-only, which meant we were depending on the server sending a proper EPERM failure for various commands, and also exposes a leaky abstraction: using qemu-io in read-write mode would succeed on 'w -z 0 0' because of local short-circuiting logic, but 'w 0 0' would send a request over the wire (where it then depends on the server, and fails at least for qemu-nbd but might pass for other NBD implementations). With this patch, a client MUST request read-only mode to access a server that is doing a read-only export, or else it will get a message like: can't open device nbd://localhost:10809/foo: request for write access conflicts with read-only export It is no longer possible to even attempt writes over the wire (including the corner case of 0-length writes), because the block layer enforces the explicit read-only request; this matches the behavior of qcow2 when backed by a read-only POSIX file. Fix several iotests to comply with the new behavior (since qemu-nbd of an internal snapshot, as well as nbd-server-add over QMP, default to a read-only export, we must tell blockdev-add/qemu-io to set up a read-only client).

2017-10-26qemu-io: Relax 'alloc' now that block-status doesn't assertEric Blake
Previously, the alloc command required that input parameters be sector-aligned and clamped to 32 bits, because the underlying bdrv_is_allocated used a 32-bit parameter and asserted aligned inputs. But now that we have fixed block status to report a 64-bit bytes value, and to properly round requests on behalf of guests, we can pass any values, and can use qemu-io to add coverage that our rounding is correct regardless of the guest alignment constraints. Update iotest 177 to intentionally probe block status at unaligned boundaries as well as with a bytes value that does not map to 32-bit sectors, which also required tweaking the image prep to leave an unallocated portion to the image under test.

2017-10-26qemu-img: Drop redundant error message in compareEric Blake
If a read error is encountered during 'qemu-img compare', we were printing the "Error while reading offset ..." message twice; this was because our helper function was awkward, printing output on some but not all paths. Fix it to consistently report errors on all paths, so that the callers do not risk a redundant message, and update the testsuite for the improved output. Further simplify the code by hoisting the conversion from an error message to an exit code into the helper function, rather than repeating that logic at all callers (yes, the helper function is now less generic, but it's a net win in lines of code).

2017-10-06iotests: Fix 195 if IMGFMT is part of TEST_DIRMax Reitz
do_run_qemu() in iotest 195 first applies _filter_imgfmt when printing qemu's command line and _filter_testdir only afterwards. Therefore, if the image format is part of the test directory path, _filter_testdir will no longer apply and the actual output will differ from the reference output even in case of success. For example, TEST_DIR might be "/tmp/test-qcow2", in which case _filter_imgfmt first transforms this to "/tmp/test-IMGFMT" which is no longer recognized as the TEST_DIR by _filter_testdir. Fix this by not applying _filter_imgfmt in do_run_qemu() but in run_qemu() instead, and only after _filter_testdir.

2017-10-06iotests: Add test 197 for covering copy-on-readEric Blake
Add a test for qcow2 copy-on-read behavior, including exposure for the just-fixed bugs. The copy-on-read behavior is always to a qcow2 image, but the test is careful to allow running with most image protocol/format combos as the backing file being copied from (luks being the exception, as it is harder to pass the right secret to all the right places). In fact, for './check nbd', this appears to be the first time we've had a qcow2 image wrapping NBD, requiring an additional line in _filter_img_create to match the similar line in _filter_img_info. Invoking blkdebug to prove we don't write too much took some effort to get working; and it requires that $TEST_WRAP (based on $TEST_DIR) not be subject to word splitting. We may decide later to have the entire iotests suite use relative rather than absolute names, to avoid problems inherited by the absolute name of $PWD or $TEST_DIR, at which point the sanity check in this commit could be simplified. This test requires at least 2G of consecutive memory to succeed; as such, it is prone to spurious failures, particularly on 32-bit machines under load. This situation is detected and triggers an early exit to skip the test, rather than a failure. To manually provoke this setup on a beefier machine, I used: $ (ulimit -S -v 1000000; ./check -qcow2 197) Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-10-06iotests: Restore stty settings on completionEric Blake
Executing qemu with a terminal as stdin will temporarily alter stty settings on that terminal (for example, disabling echo), because of how we run both the monitor and any multiplexing with guest input. Normally, qemu restores the original settings on exit; but if an iotest triggers qemu to abort in the middle, we can be left with the altered terminal setup. This can make life very annoying when debugging an iotest failure (not everyone remembers the trick of blind-typing 'stty sane' without echo, and some people prefer terminal settings that are slightly different than the defaults picked by 'stty sane'). It is possible to avoid qemu corrupting the terminal by not passing a terminal to qemu's stdin in the first place (as in, use './check ... </dev/null'), but that's extra typing to have to remember. But running 'exec </dev/null' in the harness seems like it might be too heavy of a hammer. So I instead went the the solution of saving and restoring the stty settings, only when the harness detects that it is run interactively. I tested this patch by forcing an allocation failure (I can't guarantee that this particular limit will work on all setups, but it shows the idea): $ (ulimit -S -v 500000; ./check -qcow2 1) Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-10-06commit: Remove overlay_bsKevin Wolf

The overlay node was previously added to the block job to get a BLK_PERM_GRAPH_MOD. We really need to respect those permissions in bdrv_drop_intermediate() now, but as long as we haven't figured out yet how BLK_PERM_GRAPH_MOD is actually supposed to work, just leave a TODO comment there.

2017-10-06qcow2: Switch store_bitmap_data() to byte-based iterationEric Blake
Now that we have adjusted the majority of the calls this function makes to be byte-based, it is easier to read the code if it makes passes over the image using bytes rather than sectors. iotests 165 was rather weak - on a default 64k-cluster image, where bitmap granularity also defaults to 64k bytes, a single cluster of the bitmap table thus covers (64*1024*8) bits which each cover 64k bytes, or 32G of image space. But the test only uses a 1G image, so it cannot trigger any more than one loop of the code in store_bitmap_data(); and it was writing to the first cluster. In order to test that we are properly aligning which portions of the bitmap are being written to the file, we really want to test a case where the first dirty bit returned by bdrv_dirty_iter_next() is not aligned to the start of a cluster, which we can do by modifying the test to write data that doesn't happen to fall in the first cluster of the image.

2017-09-26iotests: use virtio aliases for 067Cornelia Huck
The default cpu model on s390x does not provide zPCI, which is not yet wired up on tcg. Moreover, virtio-ccw is the standard on s390x. Using virtio-scsi will implicitly pick the right device, so just switch to that for simplicity.

2017-09-26qemu-iotests: Add missing -machine accel=qtestKevin Wolf
A basic set of qemu options is initialised in ./common: export QEMU_OPTIONS="-nodefaults -machine accel=qtest" However, two test cases (172 and 186) overwrite QEMU_OPTIONS and neglect to manually set '-machine accel=qtest'. Add the missing option for 172. 186 probably only copied the code from 172, it doesn't actually need to overwrite QEMU_OPTIONS, so remove that in 186.
