[Git][openldap/openldap][OPENLDAP_REL_ENG_2_5] 243 commits: ITS#9370 check for equality rule on old_rdn

Quanah Gibson-Mount pushed to branch OPENLDAP_REL_ENG_2_5 at openldap / OpenLDAP Commits: a08a2db4 by Howard Chu at 2020-10-19T14:03:41+01:00 ITS#9370 check for equality rule on old_rdn We should probably just check in dnNormalize instead, and catch this everywhere DNs are received.

When SASL bind finishes, we might still have to maintain a link between the client an an upstream for future bind operations if we got a SASL Bind in Progress result code. We zero out the msgids and remember a server-unique identifer on the client and the relevant operation that lets us retrieve that link again. This operation is reclaimed just like anything else when connections drop. Hopefully, this should work for LDAP TXN and VC Exop support with SASL later as well since it allows for many-to-many links to exist. - - - - - ee893ae1 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Handle EXTERNAL mechanism Will only try to extract the TLS client certificate name if used during the last handshake. - - - - - 72ca7112 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Do not compare c_auth when NULL - - - - - c52328f6 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Clear c_auth on every bind request For a new bind request, this is obvious, for SASL bind requests, we do not know the final identity until we have finished handling it, make sure it stays empty until then. - - - - - 5c1245de by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Manage c_sasl_bind_mech on upstream - - - - - 2ba83368 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Operation abandon related fixes - - - - - cbc0ec04 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Fix pinned operation forwarding - - - - - 205db0bf by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Reset pin on simple bind - - - - - c957bb91 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Add SASL documentation on SASL handling - - - - - 7a69017f by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Resolve authzid after a successful auth - - - - - 9baa56ad by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Update tests to support lloadd as a module - - - - - 2d330325 by Nadezhda Ivanova at 2020-11-17T17:58:14+00:00 Lload cn=monitor initial implementation - - - - - 77716069 by Nadezhda Ivanova at 2020-11-17T17:58:14+00:00 Use slapd's config.h - - - - - 678fa100 by Nadezhda Ivanova at 2020-11-17T17:58:14+00:00 Convert the load balancer into a backend - - - - - dab90547 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Rework monitor startup Takes care of dealing with monitor not present/not configured and fix a monitor startup issue. - - - - - 22818e85 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Module shutdown - - - - - db5966f6 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 More meaningful connection type reporting - - - - - 485a1697 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Implement pause handlers - - - - - 9bd90a74 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Fix a race on bind response processing.

When SASL bind finishes, we might still have to maintain a link between the client an an upstream for future bind operations if we got a SASL Bind in Progress result code. We zero out the msgids and remember a server-unique identifer on the client and the relevant operation that lets us retrieve that link again. This operation is reclaimed just like anything else when connections drop. Hopefully, this should work for LDAP TXN and VC Exop support with SASL later as well since it allows for many-to-many links to exist. - - - - - ee893ae1 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Handle EXTERNAL mechanism Will only try to extract the TLS client certificate name if used during the last handshake. - - - - - 72ca7112 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Do not compare c_auth when NULL - - - - - c52328f6 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Clear c_auth on every bind request For a new bind request, this is obvious, for SASL bind requests, we do not know the final identity until we have finished handling it, make sure it stays empty until then. - - - - - 5c1245de by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Manage c_sasl_bind_mech on upstream - - - - - 2ba83368 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Operation abandon related fixes - - - - - cbc0ec04 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Fix pinned operation forwarding - - - - - 205db0bf by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Reset pin on simple bind - - - - - c957bb91 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Add SASL documentation on SASL handling - - - - - 7a69017f by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Resolve authzid after a successful auth - - - - - 9baa56ad by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Update tests to support lloadd as a module - - - - - 2d330325 by Nadezhda Ivanova at 2020-11-17T17:58:14+00:00 Lload cn=monitor initial implementation - - - - - 77716069 by Nadezhda Ivanova at 2020-11-17T17:58:14+00:00 Use slapd's config.h - - - - - 678fa100 by Nadezhda Ivanova at 2020-11-17T17:58:14+00:00 Convert the load balancer into a backend - - - - - dab90547 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Rework monitor startup Takes care of dealing with monitor not present/not configured and fix a monitor startup issue. - - - - - 22818e85 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Module shutdown - - - - - db5966f6 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 More meaningful connection type reporting - - - - - 485a1697 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Implement pause handlers - - - - - 9bd90a74 by Ondřej Kuzník at 2020-11-17T17:58:14+00:00 Fix a race on bind response processing.
