sudo: don't get stuck in rules and smart refresh when offline
https://fedorahosted.org/sssd/ticket/1682 The problem was in following code: if (ret != EOK || state->dp_error != DP_ERR_OK || state->error != EOK) { tevent_req_error(req, ret); return; } In situation when data provider error occurs (e.g. when offline), ret == EOK but dp_error != DP_ERR_OK and we take the true branch. This results in calling tevent_req_error(req, EOK). Unfortunately, with EOK tevent_req_error only returns false, but does not trigger callback and this tevent request hangs forever, because no tevent_req_done(req) is called.
