2018-08-24json: Fix streamer not to ignore trailing unterminated structuresMarkus Armbruster
json_message_process_token() accumulates tokens until it got the sequence of tokens that comprise a single JSON value (it counts curly braces and square brackets to decide). It feeds those token sequences to json_parser_parse(). If a non-empty sequence of tokens remains at the end of the parse, it's silently ignored. check-qjson.c cases unterminated_array(), unterminated_array_comma(), unterminated_dict(), unterminated_dict_comma() demonstrate this bug. Fix as follows. Introduce a JSON_END_OF_INPUT token. When the streamer receives it, it feeds the accumulated tokens to json_parser_parse().

2018-08-24qjson: Fix qobject_from_json() & friends for multiple valuesMarkus Armbruster
qobject_from_json() & friends use the consume_json() callback to receive either a value or an error from the parser. When they are fed a string that contains more than either one JSON value or one JSON syntax error, consume_json() gets called multiple times. When the last call receives a value, qobject_from_json() returns that value. Any other values are leaked. When any call receives an error, qobject_from_json() sets the first error received. Any other errors are thrown away. When values follow errors, qobject_from_json() returns both a value and sets an error. That's bad. Impact: * block.c's parse_json_protocol() ignores and leaks the value. It's used to to parse pseudo-filenames starting with "json:". The pseudo-filenames can come from the user or from image meta-data such as a QCOW2 image's backing file name. * vl.c's parse_display_qapi() ignores and leaks the error. It's used to parse the argument of command line option -display. * vl.c's main() case QEMU_OPTION_blockdev ignores the error and leaves it in @err. main() will then pass a pointer to a non-null Error * to net_init_clients(), which is forbidden. It can lead to assertion failure or other misbehavior. * check-qjson.c's multiple_values() demonstrates the badness. * The other callers are not affected since they only pass strings with exactly one JSON value or, in the case of negative tests, one error. The impact on the _nofail() functions is relatively harmless. They abort when any call receives an error. Else they return the last value, and leak the others, if any. Fix consume_json() as follows. On the first call, save value and error as before. On subsequent calls, if any, don't save them. If the first call saved a value, the next call, if any, replaces the value by an "Expecting at most one JSON value" error. Take care not to leak values or errors that aren't saved.

Support for %I64d got added in commit 2c0d4b36e7f "json: fix PRId64 on Win32". We had to hard-code I64d because we used the lexer's finite state machine to check interpolations.

2018-08-24json: Leave rejecting invalid interpolation to parserMarkus Armbruster
Both lexer and parser reject invalid interpolation specifications. The parser's check is useless. The lexer ends the token right after the first bad character. This tends to lead to suboptimal error reporting. For instance, input [ %04d ] produces the tokens JSON_LSQUARE [ JSON_ERROR %0 JSON_INTEGER 4 JSON_KEYWORD d JSON_RSQUARE ] The parser then yields an error, an object and two more errors: error: Invalid JSON syntax object: 4 error: JSON parse error, invalid keyword error: JSON parse error, expecting value Dumb down the lexer to accept [A-Za-z0-9]*. The parser's check is now used. Emit a proper error there. The lexer now produces JSON_LSQUARE [ JSON_INTERP %04d JSON_RSQUARE ] and the parser reports just JSON parse error, invalid interpolation '%04d' Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20180823164025.12553-41-armbru@redhat.com>
2018-08-24json: Pass lexical errors and limit violations to callbackMarkus Armbruster
The callback to consume JSON values takes QObject *json, Error *err. If both are null, the callback is supposed to make up an error by itself. This sucks. qjson.c's consume_json() neglects to do so, which makes qobject_from_json() null instead of failing. I consider that a bug. The culprit is json_message_process_token(): it passes two null pointers when it runs into a lexical error or a limit violation. Fix it to pass a proper Error object then. Update the callbacks: * monitor.c's handle_qmp_command(): the code to make up an error is now dead, drop it. * qga/main.c's process_event(): lumps the "both null" case together with the "not a JSON object" case. The former is now gone. The error message "Invalid JSON syntax" is misleading for the latter. Improve it to "Input must be a JSON object". * qobject/qjson.c's consume_json(): no update; check-qjson demonstrates qobject_from_json() now sets an error on lexical errors, but still doesn't on some other errors. * tests/libqtest.c's qmp_response(): the Error object is now reliable, so use it to improve the error message.

2018-08-24json: Treat unwanted interpolation as lexical errorMarkus Armbruster
The JSON parser optionally supports interpolation. The lexer recognizes interpolation tokens unconditionally. The parser rejects them when interpolation is disabled, in parse_interpolation(). However, it neglects to set an error then, which can make json_parser_parse() fail without setting an error. Move the check for unwanted interpolation from the parser's parse_interpolation() into the lexer's finite state machine. When interpolation is disabled, '%' is now handled like any other unexpected character. The next commit will improve how such lexical errors are handled.

2018-08-24json: Redesign the callback to consume JSON valuesMarkus Armbruster
The classical way to structure parser and lexer is to have the client call the parser to get an abstract syntax tree, the parser call the lexer to get the next token, and the lexer call some function to get input characters. Another way to structure them would be to have the client feed characters to the lexer, the lexer feed tokens to the parser, and the parser feed abstract syntax trees to some callback provided by the client. This way is more easily integrated into an event loop that dispatches input characters as they arrive. Our JSON parser is kind of between the two. The lexer feeds tokens to a "streamer" instead of a real parser. The streamer accumulates tokens until it got the sequence of tokens that comprise a single JSON value (it counts curly braces and square brackets to decide). It feeds those token sequences to a callback provided by the client. The callback passes each token sequence to the parser, and gets back an abstract syntax tree. I figure it was done that way to make a straightforward recursive descent parser possible. "Get next token" becomes "pop the first token off the token sequence". Drawback: we need to store a complete token sequence. Each token eats 13 + input characters + malloc overhead bytes. Observations: 1. This is not the only way to use recursive descent. If we replaced "get next token" by a coroutine yield, we could do without a streamer. 2. The lexer reports errors by passing a JSON_ERROR token to the streamer. This communicates the offending input characters and their location, but no more. 3. The streamer reports errors by passing a null token sequence to the callback. The (already poor) lexical error information is thrown away. 4. Having the callback receive a token sequence duplicates the code to convert token sequence to abstract syntax tree in every callback. 5. Known bug: the streamer silently drops incomplete token sequences. This commit rectifies 4. by lifting the call of the parser from the callbacks into the streamer. Later commits will address 3. and 5. The lifting removes a bug from qjson.c's parse_json(): it passed a pointer to a non-null Error * in certain cases, as demonstrated by check-qjson.c. json_parser_parse() is now unused. It's a stupid wrapper around json_parser_parse_err(). Drop it, and rename json_parser_parse_err() to json_parser_parse().

2018-08-23tests/device-introspect: Test with all machines, not only with "none"Thomas Huth
Certain device introspection crashes used to only happen if you were using a certain machine, e.g. if the machine was using serial_hd() or nd_table[], and a device was trying to use these in its instance_init function, too. To be able to catch these problems, let's extend the device-introspect test to check the devices on all machine types, with and without the "-nodefaults" parameter (since this makes a difference sometimes, too). Since this is a rather slow operation, and most of the problems are already handled by testing with the "none" machine only, the test with all machines is only run in the "make check SPEED=slow" mode.

2018-08-23tests/device-introspection: Check that the qom-tree and qtree do not changeThomas Huth
Introspection should not change the qom-tree / qtree, so we should check this in the device-introspect-test, too. This patch helped to find lots of instrospection bugs during the QEMU v3.0 soft/hard-freeze period in the last two months.

2018-08-23tests: Skip old versioned machine types in quick testing modeThomas Huth
The tests that check something for all machine types currently spend a lot of time checking old machine types (like "pc-i440fx-2.0" for example). The chances that we find something new there in addition to checking the latest version of a machine type are pretty low, so we should not waste the time of the developers by testing this again and again in the "quick" testing mode. Thus let's add some code to determine whether we are testing a current machine type or an old one, and only test the old types if we are running in "SPEED=slow" mode. This decreases the testing time quite a bit now, e.g. the qom-test now finishes within 4 seconds for qemu-system-x86_64 instead of 30 seconds when testing all machines.

2018-08-23tests/migration-test: Silence the kvm_hv message by defaultThomas Huth
When running "make check" on a non-POWER host, the output is quite distorted like this: [...] GTESTER check-qtest-nios2 GTESTER check-qtest-or1k GTESTER check-qtest-ppc64 Skipping test: kvm_hv not available Skipping test: kvm_hv not available Skipping test: kvm_hv not available Skipping test: kvm_hv not available GTESTER check-qtest-ppcemb GTESTER check-qtest-ppc GTESTER check-qtest-riscv32 GTESTER check-qtest-riscv64 [...] Move the check to the beginning of the main function instead, so that we do not have to test the condition again and again for each test, and better use g_test_message() instead of g_print() here, like it is also done in ufd_version_check() already.

2018-08-23tests: virtio: separate ccw tests from libqosPaolo Bonzini
Because qtest does not support s390 channel I/O, s390 only performs smoke tests on those few devices that do not have any functional tests. Therefore, every time we add functional tests for a virtio device, the choice is between removing those tests from the s390 suite (so that s390 actually _loses_ coverage) or sprinkling the test with architecture checks. This patch simply creates a ccw-specific test that only performs smoke tests on all virtio-ccw devices. If channel I/O support is ever added to qtest and libqos, then this file can go away. In the meanwhile, it simplifies maintenance and makes sure that all virtio devices are tested.
