[Issue 10302] New: Double free of idcursor

While I can't share the LDIF in question and it didn't consistently cause the issue, only every 5-6 times it ran, I could ran gdb and valgrind on it and suggest the attached patch that resolves that error to re-occur. I validated the patch still applies to the current master branch of openldap, as well as to 2.6.6 on EL9 where we encountered this.

[Issue 10020] New: dynlist's @groupOfUniqueNames is considered only for the first configuration line
by openldap-its＠openldap.org 23 May '25

23 May '25

https://bugs.openldap.org/show_bug.cgi?id=10020 Issue ID: 10020 Summary: dynlist's @groupOfUniqueNames is considered only for the first configuration line Product: OpenLDAP Version: 2.5.13 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: msl(a)touk.pl Target Milestone: --- If we consider the following configuration of dynlist: {0}toukPerson labeledURI uniqueMember+memberOf@groupOfUniqueNames {1}groupOfURLs memberURL uniqueMember+dgMemberOf@groupOfUniqueNames The {0} entry will correctly populate the memberOf relatively to static group membership. The {1} entry will produce dgMemberOf with dynamic group membership correctly (based on memberURL query) but it will not populate static entries IF {0} entry in configuration is present. IF I remove {0} from the dynlist configuration - or - remove @groupOfUniqueNames part from this configuration line, then both dynamic and static entries will be populated correctly for {1}. So the effects are as follows on some user entry: if both {0} and {1} are present - {1} produced only dynamic groups: memberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl memberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl if both {0} and {1} are present and @groupOfUniqueNames is removed from {0} - {1} produced static+dynamic groups: dgMemberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl dgMemberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl If only {1} is present - {1} produced static+dynamic groups: dgMemberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl dgMemberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl For completness - if only {0} is present: memberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl memberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl I would expect this behavior to be correct for the first case - {0} and {1}. memberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl memberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl dgMemberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl dgMemberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl -- You are receiving this mail because: You are on the CC list for the issue.
