If you compile a client --without-polkit, and connect to a URI that needs polkit auth, the connection will fail with: $ ./tools/virsh --connect qemu+ssh://crobinso@machine/system error: failed to connect to the hypervisor error: authentication failed: unsupported authentication type 2 This is because the client side portion of the polkit handling is compiled out. However, nothing polkit specific is actually required of the client. Fix that error by unconditionally compiling the basic polkit client handling. https://bugzilla.redhat.com/show_bug.cgi?id=635529 --- Granted, if polkit needs to do any interaction at all, and you are connecting to a remote machine, then things are going to fail anyways with a 'missing agent' error. But if you're user is in the 'libvirt' group polkit doesn't need to auth it should all work. src/remote/remote_driver.c | 69 +++++++++++++++++++++------------------------- 1 file changed, 31 insertions(+), 38 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index da94411..6bed2c5 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -132,11 +132,9 @@ static int remoteAuthenticate(virConnectPtr conn, struct private_data *priv, #if WITH_SASL static int remoteAuthSASL(virConnectPtr conn, struct private_data *priv, virConnectAuthPtr auth, const char *mech); -#endif -#if WITH_POLKIT +#endif /* WITH_SASL */ static int remoteAuthPolkit(virConnectPtr conn, struct private_data *priv, virConnectAuthPtr auth); -#endif /* WITH_POLKIT */ static virDomainPtr get_nonnull_domain(virConnectPtr conn, remote_nonnull_domain domain); static virNetworkPtr get_nonnull_network(virConnectPtr conn, remote_nonnull_network network); @@ -3326,14 +3324,12 @@ remoteAuthenticate(virConnectPtr conn, struct private_data *priv, } #endif -#if WITH_POLKIT case REMOTE_AUTH_POLKIT: if (remoteAuthPolkit(conn, priv, auth) < 0) { VIR_FREE(ret.types.types_val); return -1; } break; -#endif case REMOTE_AUTH_NONE: /* Nothing todo, hurrah ! */ @@ -3904,30 +3900,10 @@ remoteAuthSASL(virConnectPtr conn, struct private_data *priv, #endif /* WITH_SASL */ -#if WITH_POLKIT -# if WITH_POLKIT1 -static int -remoteAuthPolkit(virConnectPtr conn, struct private_data *priv, - virConnectAuthPtr auth ATTRIBUTE_UNUSED) -{ - remote_auth_polkit_ret ret; - VIR_DEBUG("Client initialize PolicyKit-1 authentication"); - - memset(&ret, 0, sizeof(ret)); - if (call(conn, priv, 0, REMOTE_PROC_AUTH_POLKIT, - (xdrproc_t) xdr_void, (char *)NULL, - (xdrproc_t) xdr_remote_auth_polkit_ret, (char *) &ret) != 0) { - return -1; /* virError already set by call */ - } - - VIR_DEBUG("PolicyKit-1 authentication complete"); - return 0; -} -# elif WITH_POLKIT0 -/* Perform the PolicyKit authentication process - */ +#if WITH_POLKIT0 +/* Perform the PolicyKit0 authentication process */ static int -remoteAuthPolkit(virConnectPtr conn, struct private_data *priv, +remoteAuthPolkit0(virConnectPtr conn, struct private_data *priv, virConnectAuthPtr auth) { remote_auth_polkit_ret ret; @@ -3943,14 +3919,8 @@ remoteAuthPolkit(virConnectPtr conn, struct private_data *priv, }; VIR_DEBUG("Client initialize PolicyKit-0 authentication"); - /* Check auth first and if it succeeds we are done. */ - memset(&ret, 0, sizeof(ret)); - if (call(conn, priv, 0, REMOTE_PROC_AUTH_POLKIT, - (xdrproc_t) xdr_void, (char *)NULL, - (xdrproc_t) xdr_remote_auth_polkit_ret, (char *) &ret) == 0) - goto out; - - /* Auth failed.
