authz: add QAuthZList object type for an access control list Add a QAuthZList object type that implements the QAuthZ interface. This built-in implementation maintains a trivial access control list with a sequence of match rules and a final default policy. This replicates the functionality currently provided by the qemu_acl module. To create an instance of this object via the QMP monitor, the syntax used would be: { "execute": "object-add", "arguments": { "qom-type": "authz-list", "id": "authz0", "props": { "rules": [ { "match": "fred", "policy": "allow", "format": "exact" }, { "match": "bob", "policy": "allow", "format": "exact" }, { "match": "danb", "policy": "deny", "format": "glob" }, { "match": "dan*", "policy": "allow", "format": "exact" }, ], "policy": "deny" } } } This sets up an authorization rule that allows 'fred', 'bob' and anyone whose name starts with 'dan', except for 'danb'. Everyone unmatched is denied. It is not currently possible to create this via -object, since there is no syntax supported to specify non-scalar properties for objects. This is likely to be addressed by later support for using JSON with -object, or an equivalent approach. In any case the future "authz-listfile" object can be used from the CLI and is likely a better choice, as it allows the ACL to be refreshed automatically on change.
