I realized the issue I'd hit was with replicating cn=config when modifying this attribute. Likely the missing matching rules issue that's tracked under another ITS I need to address. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

I've put a comment there. As for BackendInfo, there should be no difference as far as I understand. But there is probably quite a bit of context I'm still missing. -- Ondřej Kuzník Senior Software Engineer Symas Corporation http://www.symas.com Packaged, certified, and supported LDAP solutions powered by OpenLDAP

(ITS#8859) Support backends without a database
by ondra＠openldap.org 21 May '18

21 May '18

Full_Name: Ondrej Kuznik Version: master OS: URL: https://github.com/mistotebe/openldap/tree/ITS8859 Submission from: (NULL) (82.10.24.68) In order to support the load balancer within the slapd process and integrate correctly, we declare it to be a backend as that is the best match - allows us to register all the callbacks that a subsystem like this needs. The only problem is that slapd will skip startup for backends that are not used by at least one database. The linked patch deals with this limitation and a few bugs encountered along the way (some code has not been exercised in a long time and has suffered from some bitrot). The support to provide backend global configuration was nominally present but has never worked with cn=config. The first two patches deal with that. The last patch introduces a new backend flag that indicates that it should be started up even if there is no database using it. IPR notice: The linked files are derived from OpenLDAP Software.

(ITS#8858) Walking the thread pool work queue
by ondra＠openldap.org 21 May '18

21 May '18

Full_Name: Ondrej Kuznik Version: master OS: URL: https://github.com/mistotebe/openldap/tree/ITS8858 Submission from: (NULL) (82.10.24.68) During reconfiguration, the load balancer might need to dispose of some resources (connections, ...) as the new configuration invalidates their state. Due to how pool pause is handled in libldap_r, tasks might still be queued in there that reference those objects and need to be de-queued before we resume. Most of the time, it is sufficient to record the cookie from pool_submit2 and use pool_retract. At least in some phases of the load balancer implementation we could have more than one task scheduled for the same object - with reconfiguration being the rare case, optimising for it at the expense of the common case does not feel right. The linked patch is ready for review, it lets the caller examine the tasks with a specified start_routine and have any of them retracted where appropriate.

The response queue will indeed grow without bound if the consumer runs slower than the provider, and doesn't read responses fast enough. But in the case of this test script, eventually the client finishes and the consumer catches up. The provider's process size may not decrease, but that just means the malloc implementation isn't returning freed memory to the kernel - it's not a leak. This can be verified using mleak, and using SIGPROF to snapshot the memory usage of the provider. The simplest way to force the memory use to grow is to first suspend the consumer with SIGSTOP. Let the modify client run to completion. mleak / SIGPROF will show a large amount of memory in use. Resume the consumer with SIGCONT, let it run to completion, and then check with SIGPROF on the provider again - all of the response queue memory is freed. So, conclusively, there is no actual leak. But there's a problem with sustained client modifications when the consumer is too slow. Our options here are to configure a size limit on the response queue, and hang the client when the limit is hit, or to return LDAP_BUSY to the client. Neither of these are very attractive options. Doing batched commits will speed up the consumer, but that feature is only in 2.5. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
