[Bug 9256] New: The ACLs required for SASL binding are not fully documented
by openldap-its＠openldap.org 05 Dec '25

https://bugs.openldap.org/show_bug.cgi?id=9256 Bug ID: 9256 Summary: The ACLs required for SASL binding are not fully documented Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: documentation Assignee: bugs(a)openldap.org Reporter: kop(a)karlpinc.com Target Milestone: --- Created attachment 727 --> https://bugs.openldap.org/attachment.cgi?id=727&action=edit Patch massaging the SASL binding requirement docs While some ACL requirements for SASL binding are documented, some are not. E.g, that olcAuthzRegexp requires =x on objectClass when direct DN mapping is not documented. Other requirements can be reasoned out based on the existing documentation, but this can be very difficult when unfamiliar with all the moving parts and the places they are documented. E.g. knowing that (objectClass=*) is the default filter, and that there's _always_ _some_ filter, and connecting this with ACLs required to do search-based SASL mapping. The attached patch brings all the SASL binding requirements together in one place in the docs and makes everything explicit. The word "SASL" is included, for those searching for that keyword.

[Issue 9731] New: startup messages still go to syslog when logfile-only is on

[Issue 9726] New: Admin guide and man pages need better documentation on disabling syslog

[Issue 9564] New: Race condition with freeing the spilled pages from transaction
by openldap-its＠openldap.org 05 Nov '25

https://bugs.openldap.org/show_bug.cgi?id=9564 Issue ID: 9564 Summary: Race condition with freeing the spilled pages from transaction Product: LMDB Version: 0.9.29 Hardware: Other OS: Mac OS Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: kriszyp(a)gmail.com Target Milestone: --- Created attachment 825 --> https://bugs.openldap.org/attachment.cgi?id=825&action=edit Free the spilled pages and dirty overflows before unlocking the write mutex The spilled pages (a transaction's mt_spill_pgs) is freed *after* a write transaction's mutex is unlocked (in mdb.master3). This can result in a race condition where a second transaction can start and subsequently assign a new mt_spill_pgs list to the transaction structure that it reuses. If this occurs after the first transaction unlocks the mutex, but before it performs the free operation on mt_spill_pgs, then the first transaction will end up calling a free on the same spilled page list as the second transaction, resulting in a double free (and crash). It would seem to be an extremely unlikely scenario to actually happen, since the free call is literally the next operation after the mutex is unlocked, and the second transaction would need to make it all the way to the point of saving the freelist before a page spill list is likely to be allocated. Consequently, this probably has rarely happened. However, one of our users (see https://github.com/DoctorEvidence/lmdb-store/issues/48 for the discussion) has noticed this occurring, and it seems that it may be particularly likely to happen on MacOS on the new M1 silicon. Perhaps there is some peculiarity to how the threads are more likely to yield execution after a mutex unlock, I am not sure. I was able to reproduce the issue by intentionally manipulating the timing (sleeping before the free) to verify that the race condition is technically feasible, and apparently this can happen "in the wild" on MacOS, at least with an M1. It is also worth noting that this is due to (or a regression from) the fix for ITS#9155 (https://github.com/LMDB/lmdb/commit/cb256f409bb53efeda4ac69ee8165a0b4fc1a277) where the free call was moved outside the conditional (for having a parent) that had previously never been executed after the mutex is unlocked, but now is called after the unlock. Anyway, the solution is relatively simple, the free call simply has to be moved above the unlock. In my patch, I also moved the free call for mt_dirty_ovs. I am not sure what OVERFLOW_NOTYET/mt_dirty_ovs is for, but presumably it should be handled the same. This could alternately be solved by saving the reference to these lists before unlocking, and freeing after unlocking, which would slightly decrease the amount of processing within the mutex guarded code. Let me know if you prefer a patch that does that. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10397] New: Presence of "auditContext" in root database entry can break replication

https://bugs.openldap.org/show_bug.cgi?id=10397 Issue ID: 10397 Summary: Presence of "auditContext" in root database entry can break replication Product: OpenLDAP Version: 2.6.10 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- When bootstrapping a new environment, I found that the: "auditContext: cn=accesslog" attribute that is added on a provider breaks replication when attempting to replicate to a consumer that has no database present and lacks the accesslog overlay, since that is what defines the attribute in question. Instead we get a corrupted entry with an inability to write to the local database. -- You are receiving this mail because: You are on the CC list for the issue.
