2021-09-15tests: add migrate-during-backupVladimir Sementsov-Ogievskiy
Add a simple test which tries to run migration during backup. bdrv_inactivate_all() should fail. But due to bug (see next commit with fix) it doesn't, nodes are inactivated and continued backup crashes on assertion "assert(!(bs->open_flags & BDRV_O_INACTIVE));" in bdrv_co_write_req_prepare().

2021-09-15iotests/297: Cover tests/Hanna Reitz
297 so far does not check the named tests, which reside in the tests/ directory (i.e. full path tests/qemu-iotests/tests). Fix it. Thanks to the previous two commits, all named tests pass its scrutiny, so we do not have to add anything to SKIP_FILES.

The AbnormalShutdown exception class is not in qemu.machine, but in qemu.machine.machine. (qemu.machine.AbnormalShutdown was enough for Python to find it in order to run this test, but pylint complains about it.)

2021-09-15migrate-bitmaps-test: Fix pylint warningsHanna Reitz
There are a couple of things pylint takes issue with: - The "time" import is unused - The import order (iotests should come last) - get_bitmap_hash() doesn't use @self and so should be a function - Semicolons at the end of some lines - Parentheses after "if" - Some lines are too long (80 characters instead of 79) - inject_test_case()'s @name parameter shadows a top-level @name variable - "lambda self: mc(self)" were equivalent to just "mc", but in inject_test_case(), it is not equivalent, so add a comment and disable the warning locally - Always put two empty lines after a function - f'exec: cat > /dev/null' does not need to be an f-string Fix them.

2021-09-03tests/qapi-schema: Hide OrderedDict in test outputMarkus Armbruster
Since commit 5d83b9a130 "qapi: replace if condition list with dict {'all': [...]}", we represent if conditionals as trees consisting of OrderedDict, list and str. This results in less than legible test output. For instance: if OrderedDict([('not', OrderedDict([('any', [OrderedDict([('not', 'TEST_IF_EVT')]), OrderedDict([('not', 'TEST_IF_STRUCT')])])]))]) We intend to replace OrderedDict by dict when we get Python 3.7, which will result in more legible output: if {'not': {'any': [{'not': 'TEST_IF_EVT'}, {'not': 'TEST_IF_STRUCT'}]}} Can't wait: put in a hack to get that now, with a comment to revert it when we replace OrderedDict.

When commit 5d83b9a130 "qapi: replace if condition list with dict {'all': [...]}" made cgen_ifcond() and docgen_ifcond() recursive, it messed up parenthesises in the former, and got them right in the latter, as the previous commit demonstrates.

2021-09-03tests/qapi-schema: Demonstrate broken C code for 'if'Markus Armbruster
The C code generated for 'if' conditionals is incorrectly parenthesized. For instance, 'if': { 'not': { 'any': [ { 'not': 'TEST_IF_EVT' }, { 'not': 'TEST_IF_STRUCT' } ] } } } generates #if !(!defined(TEST_IF_EVT)) || (!defined(TEST_IF_STRUCT)) This is wrong. Correct would be: #if !(!defined(TEST_IF_EVT) || !defined(TEST_IF_STRUCT)) Cover the issue in qapi-schema-test.json. This generates bad #if in tests/test-qapi-events.h and other files. Add a similar condition to doc-good.json. The generated documentation is fine.

2021-09-03tests/qapi-schema: Correct two 'if' conditionalsMarkus Armbruster
A definition's conditional should imply the conditionals of types it uses. If it doesn't, some configurations won't compile. Example (from tests/qapi-schema/qapi-schema-test.json): { 'union': 'TestIfUnion', 'data': { 'foo': 'TestStruct', 'bar': { 'type': 'str', 'if': 'TEST_IF_UNION_BAR'} }, 'if': { 'all': ['TEST_IF_UNION', 'TEST_IF_STRUCT'] } } { 'command': 'test-if-union-cmd', 'data': { 'union-cmd-arg': 'TestIfUnion' }, 'if': 'TEST_IF_UNION' } generates #if (defined(TEST_IF_UNION)) && (defined(TEST_IF_STRUCT)) typedef struct TestIfUnion TestIfUnion; #endif /* (defined(TEST_IF_UNION)) && (defined(TEST_IF_STRUCT)) */ and #if defined(TEST_IF_UNION) void qmp_test_if_union_cmd(TestIfUnion *union_cmd_arg, Error **errp); void qmp_marshal_test_if_union_cmd(QDict *args, QObject **ret, Error **errp); #endif /* defined(TEST_IF_UNION) */ which doesn't compile when !defined(TEST_IF_STRUCT). Messed up in f8c4fdd6ae "tests/qapi: Cover commands with 'if' and union / alternate 'data'", v4.0.0. Harmless, as we don't actually use this configuration. Correct it anyway, along with another instance. This loses coverage for 'not'. The next commit will bring it back.

This commit makes the plugin adhere to the new plugins arg-passing scheme by expecting full-form boolean args instead of short-form booleans. This necessitates that we introduce a new argument, here "track", to accept "r", "w", or "rw". Also, it makes arguments not positional and we only care about the last value specified for a certain argument. callback/inline args are now supplied separately as bool arguments so that both can be enabled individually.

2021-09-01block/copy-before-write: relax permission requirements when no parentsVladimir Sementsov-Ogievskiy
We are going to publish copy-before-write filter. So, user should be able to create it with blockdev-add first, specifying both filtered and target children. And then do blockdev-reopen, to actually insert the filter where needed. Currently, filter unshares write permission unconditionally on source node. It's good, but it will not allow to do blockdev-add. So, let's relax restrictions when filter doesn't have any parent. Test output is modified, as now permission conflict happens only when job creates a blk parent for filter node.

2021-09-01fuzz: unblock SIGALRM so the timeout worksAlexander Bulekov
The timeout mechanism won't work if SIGALRM is blocked. This changes unmasks SIGALRM when the timer is installed. This doesn't completely solve the problem, as the fuzzer could trigger some device activity that re-masks SIGALRM. However, there are currently no inputs on OSS-Fuzz that re-mask SIGALRM and timeout. If that turns out to be a real issue, we could try to hook sigmask-type calls, or use a separate timer thread.

2021-09-01fuzz: use ITIMER_REAL for timeoutsAlexander Bulekov
Using ITIMER_VIRTUAL is a bad idea, if the fuzzer hits a blocking syscall - e.g. ppoll with a NULL timespec. This causes timeout issues while fuzzing some block-device code. Fix that by using wall-clock time. This might cause inputs to timeout sometimes due to scheduling effects/ambient load, but it is better than bringing the entire fuzzing process to a halt.

2021-09-01fuzz: adjust timeout to allow for longer inputsAlexander Bulekov
Using a custom timeout is useful to continue fuzzing complex devices, even after we run into some slow code-path. However, simply adding a fixed timeout to each input effectively caps the maximum input length/number of operations at some artificial value. There are two major problems with this: 1. Some code might only be reachable through long IO sequences. 2. Longer inputs can actually be _better_ for performance. While the raw number of fuzzer executions decreases with larger inputs, the number of MMIO/PIO/DMA operation/second actually increases, since were are speding proportionately less time fork()ing. With this change, we keep the custom-timeout, but we renew it, prior to each MMIO/PIO/DMA operation. Thus, we time-out only when a specific operation takes a long time.

2021-09-01fuzz: fix sparse memory access in the DMA callbackAlexander Bulekov
The code mistakenly relied on address_space_translate to store the length remaining until the next memory-region. We care about this because when there is RAM or sparse-memory neighboring on an MMIO region, we should only write up to the border, to prevent inadvertently invoking MMIO handlers within the DMA callback. However address_space_translate_internal only stores the length until the end of the MemoryRegion if memory_region_is_ram(mr). Otherwise the *len is left unmodified. This caused some false-positive issues, where the fuzzer found a way to perform a nested MMIO write through a DMA callback on an [address, length] that started within sparse memory and spanned some device MMIO regions. To fix this, write to sparse memory in small chunks of memory_access_size (similar to the underlying address_space_write code), which will prevent accidentally hitting MMIO handlers through large writes.
