The QAPI\nmethod makes the handling of the TLS strings more intuitive because it\nclones them as well.\n\nThis also fixes a segfault when a NULL TLS option is accessed as part\nof a validation check for another option (e.g. in the zero-copy +\nmultifd compression case). Details follow:\n\nCurrently, after copying s->parameters to the temporary\nMigrationParameters object before migrate_params_check(), the\nreferences in temporary object to the TLS options are dropped, either\nbecause:\n\na) the user set a new option, in which case that's fine as\n s->parameters still holds the reference to the old memory or,\n\nb) the user did not set a new option, in which case keeping the\n references in the temporary object would later cause them to be\n freed along with it, leading to double-free when s->parameters is\n also freed later on.\n\nIn this second case, it was overlooked that the TLS options can be\naccessed already during migrate_params_check() as part of validation\nof another option. Those pointers should not have been cleared.\n\nUsing QAPI_CLONE_MEMBERS fixes the issue because the temporary object\nis not stealing a reference from s->parameters anymore.\n\nFixes: aed97f0563 (\"migration: Normalize tls arguments\")\nReported-by: Maciej S.
