[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

However, there is no documentation on the new settings or examples of how to do this in the admin guide, and the man page sections on the new parameters for the logfile side do not note at when/how they enable bypassing syslog. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9564] New: Race condition with freeing the spilled pages from transaction
by openldap-its＠openldap.org 04 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 9356] New: Add list of peerSIDs to consumer cookie to reduce cross traffic

https://bugs.openldap.org/show_bug.cgi?id=9356 Issue ID: 9356 Summary: Add list of peerSIDs to consumer cookie to reduce cross traffic Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- If we add a list of peersids to the cookie, each consumer can tell the providers who else the consumers talk to and then the provider can omit sending updates to that consumer, originating from those peers There's some special handling needed if a connection dies If a consumer loses one of its peer connections, and after N retries is still not connected, it should send a new cookie to its remaining peers saying "here's my new peer list" with the missing one removed. Likewise, if a retry eventually connects again, it can send a new cookie again Make that peer list reset configurable in the syncrepl config stanza. This can help account for end admin knowledge that some links may be more or less stable than other ones. The idea here is that if one of your other peers can still see the missing peer, they can start routing updates to you again It should abandon all existing persist sessions and send a new sync search with the new cookie to all remaining peers For consumer side, also means adding the sid for a given provider into the syncrepl stanza to save on having to try and discover the peer sid. -- You are receiving this mail because: You are on the CC list for the issue.
