Add a QAuthZSimple object type that implements the QAuthZ interface. This simple 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-simple", "id": "auth0", "parameters": { "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" } } } Or via the -object command line $QEMU \ -object authz-simple,id=acl0,policy=deny,\ rules.0.match=fred,rules.0.policy=allow,rules.0.format=exact,\ rules.1.match=bob,rules.1.policy=allow,rules.1.format=exact,\ rules.2.match=danb,rules.2.policy=deny,rules.2.format=glob,\ rules.3.match=dan\*,rules.3.policy=allow,rules.3.format=exact This sets up an authorization rule that allows 'fred', 'bob' and anyone whose name starts with 'dan', except for 'danb'. Everyone unmatched is denied. Signed-off-by: Daniel P.
