[Issue 9359] New: syncrepl_op_modify can create invalid mods
by openldap-its＠openldap.org 12 Oct '20

12 Oct '20

https://bugs.openldap.org/show_bug.cgi?id=9359 Issue ID: 9359 Summary: syncrepl_op_modify can create invalid mods Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: replication Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- In Delta MPR, if a modify gets delayed in reaching another server and another (later) modify has already changed that entry, its parts are checked by syncrepl_op_modify. Replaces will then be split into a delete+add pairs so they can be resolved separately, but a bug in mods_dup happily creates an (illegal) empty add if the replace didn't contain any values. Fix coming. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9355] New: Delta-sync MPR can fail to recreate entries
by openldap-its＠openldap.org 12 Oct '20

12 Oct '20

https://bugs.openldap.org/show_bug.cgi?id=9355 Issue ID: 9355 Summary: Delta-sync MPR can fail to recreate entries Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- If an entry is missing on one host and a mod for that DN comes in from another, it should attempt a fallback to retrieve the latest version. That does not seem to happen in all cases. At least syncrepl_op_modify does not seem to propagate the error from overlay_entry_get_ov correctly, instead it ignores the mod and absorbs the CSN. https://git.openldap.org/openldap/openldap/-/merge_requests/176 -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9345] New: Restarted consumer with syncprov may have empty cookie
by openldap-its＠openldap.org 12 Oct '20

12 Oct '20

https://bugs.openldap.org/show_bug.cgi?id=9345 Issue ID: 9345 Summary: Restarted consumer with syncprov may have empty cookie Product: OpenLDAP Version: 2.4.52 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- On a relatively fresh node with both syncrepl and syncprov, after some writes have occurred, if the consumer config is deleted and re-added, it's possible the consumer won't see the current cookie. On startup it checks the local database for contextCSN, but if syncprov has been caching cookie updates it may not have been written to the DB yet. (And on an older server, the contextCSN may be present in the DB, but stale relative to the state syncprov has cached.) The consumer calls check_syncprov on subsequent iterations, but it ought to also call it on startup, just in case. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9352] New: delta-sync SEGV modifying zero-length context entry
by openldap-its＠openldap.org 12 Oct '20

https://bugs.openldap.org/show_bug.cgi?id=9352 Issue ID: 9352 Summary: delta-sync SEGV modifying zero-length context entry Product: OpenLDAP Version: 2.4.53 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- With a zero-length suffix, the context entry is usually a glue entry. It gets created without an entryCSN. If an incoming mod updates it, syncrepl will crash trying to find its entryCSN. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9330] New: Need to fully serialize delta-syncrepl
by openldap-its＠openldap.org 12 Oct '20

https://bugs.openldap.org/show_bug.cgi?id=9330 Issue ID: 9330 Summary: Need to fully serialize delta-syncrepl 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: --- While using delta-syncrepl was supposed to fully serialize updates due to the use of the accesslog DB, in extremely high write driven environments it became clear this wasn't entirely the case. This would cause systems to constantly go into mini REFRESH states as changes came in out of order. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9342] New: delta-sync: relax requirements on delete ops
by openldap-its＠openldap.org 12 Oct '20

12 Oct '20

https://bugs.openldap.org/show_bug.cgi?id=9342 Issue ID: 9342 Summary: delta-sync: relax requirements on delete ops Product: OpenLDAP Version: 2.4.52 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- Currently if the delta-sync consumer encounters any unexpected changes it always falls back to a regular refresh. We should allow it to proceed when a Delete op fails with NoSuchObject. While unexpected changes are still an indication of inconsistent logs, we can still safely advance to the next op in the sequence before giving up (if necessary) since the outcome is the same. The plain syncrepl consumer already has the same behavior for delete ops. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 8486] Syncprov sessionlog is inefficient, kills perf

https://bugs.openldap.org/show_bug.cgi?id=8486 --- Comment #11 from Quanah Gibson-Mount <quanah(a)openldap.org> --- Note: OpenLDAP 2.5 has further work converting the sessionlog to a btree: Commits: • d2036cec by Ondřej Kuzník at 2020-09-25T00:07:50+00:00 ITS#8486 Switch sessionlog to use TAVL • 8f8774c0 by Howard Chu at 2020-09-25T00:07:50+00:00 ITS#8486 Minor play_sessionlog cleanup Fix logmsg uuidstr. Shortcut finding start of playback. Allow dup CSNs in log, but with different UUIDs. All non-present deletes in a refresh use the same CSN. • 98d5c5c6 by Ondřej Kuzník at 2020-09-25T00:07:50+00:00 ITS#8486 Protect tavl_* calls in play_sessionlog • 1915cb96 by Howard Chu at 2020-09-25T00:07:50+00:00 ITS#8486 use kbtree for sessionlog Saves about 20% CPU time and RAM -- You are receiving this mail because: You are on the CC list for the issue.
