authz: add QAuthZ object as an authorization base class The current qemu_acl module provides a simple access control list facility inside QEMU, which is used via a set of monitor commands acl_show, acl_policy, acl_add, acl_remove & acl_reset. Note there is no ability to create ACLs - the network services (eg VNC server) were expected to create ACLs that they want to check. There is also no way to define ACLs on the command line, nor potentially integrate with external authorization systems like polkit, pam, ldap lookup, etc. The QAuthZ object defines a minimal abstract QOM class that can be subclassed for creating different authorization providers.

authz: add QAuthZSimple object type for easy whitelist auth checks In many cases a single VM will just need to whitelist a single identity as the allowed user of network services. This is especially the case for TLS live migration (optionally with NBD storage) where we just need to whitelist the x509 certificate distinguished name of the source QEMU host. Via QMP this can be configured with: { "execute": "object-add", "arguments": { "qom-type": "authz-simple", "id": "authz0", "props": { "identity": "fred" } } } Or via the command line -object authz-simple,id=authz0,identity=fred Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Daniel P.

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.
