With the patch nfs_rpc_callback_setup_gss() creates an AUTH structure via authnone_ncreate_dummy() and sets its ah_error.re_status to RPC_SYSTEMERROR. Afterwards nfs_rpc_create_chan_v40() checks this status with AUTH_FAILURE and sets chan->auth to NULL: chan->auth = nfs_rpc_callback_setup_gss(chan, &clientid->cid_credential); [...] if (AUTH_FAILURE(chan->auth)) { err = rpc_sperror(&chan->auth->ah_error, "failed"); LogDebug(COMPONENT_NFS_CB, "%s", err); gsh_free(err); AUTH_DESTROY(chan->auth); chan->auth = NULL; return EINVAL; }
