2019-10-28Acceptance tests: work around socket dirCleber Rosa
Change 32558ce7a4 introduced specific directories for the socket dir when using python/qemu/machine.py:QEMUMachine. iotests probably didn't catch the condition that two simultaneous QEMUMachine instances, without manually set temporary or socket dirs would clash. Having two QEMUMachine instances is a condition expected for many acceptance tests, and it's already used by the migration tests. Signed-off-by: Cleber Rosa <crosa@redhat.com>

2019-10-28crypto: add support for gcrypt's native XTS implDaniel P. Berrangé
Libgcrypt 1.8.0 added support for the XTS mode. Use this because long term we wish to delete QEMU's XTS impl to avoid carrying private crypto algorithm impls. As an added benefit, using this improves performance from 531 MB/sec to 670 MB/sec, since we are avoiding several layers of function call indirection. This is even more noticable with the gcrypt builds in Fedora or RHEL-8 which have a non-upstream patch for FIPS mode which does mutex locking. This is catastrophic for encryption performance with small block sizes, meaning this patch improves encryption from 240 MB/sec to 670 MB/sec.

This is a simple plugin to track which translation blocks are call most often.

If CONFIG_PLUGINS is enabled then lets enable testing for all our TCG targets. This is a simple smoke test that ensure we don't crash or otherwise barf out by running each plugin against each test. There is a minor knock on effect for additional runners which need specialised QEMU_OPTS which will also need to declare a plugin version of the runner. If this gets onerous we might need to add another helper. Checking the results of the plugins is left for a later exercise.

2019-10-28tests: benchmark crypto with fixed data size, not time periodDaniel P. Berrangé
Currently the crypto benchmarks are processing data in varying chunk sizes, over a fixed time period. This turns out to be a terrible idea because with small chunk sizes the overhead of checking the elapsed time on each loop iteration masks the true performance. Benchmarking over a fixed data size avoids the loop running any system calls which can interfere with the performance measurements.

2019-10-28block: Add @exact parameter to bdrv_co_truncate()Max Reitz
We have two drivers (iscsi and file-posix) that (in some cases) return success from their .bdrv_co_truncate() implementation if the block device is larger than the requested offset, but cannot be shrunk. Some callers do not want that behavior, so this patch adds a new parameter that they can use to turn off that behavior. This patch just adds the parameter and lets the block/io.c and block/block-backend.c functions pass it around. All other callers always pass false and none of the implementations evaluate it, so that this patch does not change existing behavior. Future patches take care of that.

2019-10-28iotests: Introduce $SOCK_DIRMax Reitz
Unix sockets generally have a maximum path length. Depending on your $TEST_DIR, it may be exceeded and then all tests that create and use Unix sockets there may fail. Circumvent this by adding a new scratch directory specifically for Unix socket files. It defaults to a temporary directory (mktemp -d) that is completely removed after the iotests are done. (By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which should be short enough for our use cases.) Use mkdir -p to create the directory (because it seems right), and do the same for $TEST_DIR (because there is no reason for that to be created in any different way).

2019-10-28iotests: Let skip_if_unsupported accept a functionMax Reitz
This lets tests use skip_if_unsupported() with a potentially variable list of required formats.

2019-10-28iotests: Use case_skip() in skip_if_unsupported()Max Reitz
skip_if_unsupported() should use the stronger variant case_skip(), because this allows it to be used even with setUp() (in a meaningful way). In the process, make it explicit what we expect the first argument of the func_wrapper to be (namely something derived of QMPTestCase).

2019-10-28iotests: Allow skipping test casesMax Reitz
case_notrun() does not actually skip the current test case. It just adds a "notrun" note and then returns to the caller, who manually has to skip the test. Generally, skipping a test case is as simple as returning from the current function, but not always: For example, this model does not allow skipping tests already in the setUp() function. Thus, add a QMPTestCase.case_skip() function that invokes case_notrun() and then self.skipTest(). To make this work, we need to filter the information on how many test cases were skipped from the unittest output.

2019-10-28iotests: Prefer null-co over null-aioMax Reitz
We use null-co basically everywhere in the iotests. Unless we want to test null-aio specifically, we should use it instead (for consistency).
