* qmp: add dump machine type compatibility propertiesMaksim Davydov2024-04-251-1/+1
| | | | | | | | | | | | | | | | | To control that creating new machine type doesn't affect the previous types (their compat_props) and to check complex compat_props inheritance we need qmp command to print machine type compatibility properties. This patch adds the ability to get list of all the compat_props of the corresponding supported machines for their comparison via new optional argument of "query-machines" command. Since information on compatibility properties can increase the command output by a factor of 40, add an argument to enable it, default off.

* qapi qdev qom: Elide redundant has_FOO in generated CMarkus Armbruster2022-12-141-2/+1
| | | | | | | | | | | | | | | | | | The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with. Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/qdev.json and qapi/qom.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here. Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Daniel P.

* tests/qtest: libqos: Rename malloc.h to libqos-malloc.hXuzhou Cheng2022-08-291-1/+1
| | | | | | | | | | | | | | | | | | The qtest/libqos directory is included via the "-I" option to search for header files when building qtest. Unfortunately the malloc.h has a name conflict with the standard libc header, leading to a build failure on the Windows host, due to the MinGW libc stdlib.h header file includes malloc.h and it now gets wrongly pointed to the one in the qtest/libqos directory. Rename "qtest/libqos/malloc.h" to "qtest/libqos/libqos-malloc.h" to avoid the namespace pollution.

* tests/qtest: Fix potential NULL pointer dereference in qos_build_main_args()AlexChen2020-11-031-1/+2
| | | | | | | | | | | In qos_build_main_args(), the pointer 'path' is dereferenced before checking it is valid, which may lead to NULL pointer dereference. So move the assignment to 'cmd_line' after checking 'path' is valid.

* fuzz: Expect the cmdline in a freeable GStringAlexander Bulekov2020-07-171-3/+3
| | | | | | | | | | | | | | | | In the initial FuzzTarget, get_init_cmdline returned a char *. With this API, we had no guarantee about where the string came from. For example, i440fx-qtest-reboot-fuzz simply returned a pointer to a string literal, while the QOS-based targets build the arguments out in a GString an return the gchar *str pointer. Since we did not try to free the cmdline, we have a leak for any targets that do not simply return string literals. Clean up this mess by forcing fuzz-targets to return a GString, that we can free.

* fuzz: Simplify how we compute available machines and typesMarkus Armbruster2020-04-291-25/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | apply_to_qlist(), apply_to_node() work with QObjects. This is designed for use by tests/qtest/qos-test.c, which gets the data in that form via QMP. Goes back to commit fc281c8020 "tests: qgraph API for the qtest driver framework". Commit 275ab39d86 "fuzz: add support for qos-assisted fuzz targets" added another user: qtest/fuzz/qos_fuzz.c. To get the data as QObjects, it uses qmp_marshal_query_machines() and qmp_marshal_qom_list_types(). All this code is rather cumbersome. Switch to working with generated QAPI types instead: * Replace apply_to_qlist() & friends by machines_apply_to_node() and types_apply_to_node(). * Have qos_fuzz.c use qmp_query_machines() and qmp_qom_list_types() instead. * Have qos_test.c convert from QObject to the QAPI types.
