Issue ID: 10327 Summary: Adding syncprov to cn=config can lock up server Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: backends Assignee: bugs@openldap.org Reporter: ondra@mistotebe.net Target Milestone: ---

As reported on openldap-technical[0], adding syncprov to a cn=config DB can lock up the server. This happens when syncprov_db_otask is scheduled by syncprov_db_open.

ITS#9045 has already dealt with this for config_back_entry_get, we can relax this description and allow a config_back_search do the same. Even though it is technically on a different thread than the main modification, AFAIK it is still the only one running as the server is paused and the main modification is paused waiting for it?
