54 * svcauthsw is the bdevsw of server side authentication.
56 * Server side authenticators are called from authenticate by
57 * using the client auth struct flavor field to index into svcauthsw.
58 * The server auth flavors must implement a routine that looks
62 * flavorx_auth(rqst, msg)
63 * register struct svc_req *rqst;
64 * register struct rpc_msg *msg;
68 enum auth_stat _svcauth_null(); /* no authentication */
69 enum auth_stat _svcauth_unix(); /* unix style (uid, gids) */
70 enum auth_stat _svcauth_short(); /* short hand unix style */
73 enum auth_stat (*authenticator)();
75 _svcauth_null, /* AUTH_NULL */
76 _svcauth_unix, /* AUTH_UNIX */
77 _svcauth_short, /* AUTH_SHORT */
79 #define AUTH_MAX 2 /* HIGHEST AUTH NUMBER */
83 * The call rpc message, msg has been obtained from the wire. The msg contains
84 * the raw form of credentials and verifiers. authenticate returns AUTH_OK
85 * if the msg is successfully authenticated. If AUTH_OK then the routine also
86 * does the following things:
87 * set rqst->rq_xprt->verf to the appropriate response verifier;
88 * sets rqst->rq_client_cred to the "cooked" form of the credentials.
90 * NB: rqst->rq_cxprt->verf must be pre-alloctaed;
91 * its length is set appropriately.
93 * The caller still owns and is responsible for msg->u.cmb.cred and
94 * msg->u.cmb.verf. The authentication system retains ownership of
95 * rqst->rq_client_cred, the cooked credentials.
97 * There is an assumption that any flavour less than AUTH_NULL is
101 _authenticate(rqst, msg)
102 register struct svc_req *rqst;
105 register int cred_flavor;
107 rqst->rq_cred = msg->rm_call.cb_cred;

109 rqst->rq_xprt->xp_verf.oa_length = 0;
110 cred_flavor = rqst->rq_cred.oa_flavor;
111 if ((cred_flavor <= AUTH_MAX) && (cred_flavor >= AUTH_NULL)) {
112 return ((*(svcauthsw[cred_flavor].authenticator))(rqst, msg));
115 return (AUTH_REJECTEDCRED);
