[Issue 10108] New: "mdb_dump -a" does not dump the main database
by openldap-its＠openldap.org 09 Oct '23

https://bugs.openldap.org/show_bug.cgi?id=10108 Issue ID: 10108 Summary: "mdb_dump -a" does not dump the main database Product: LMDB Version: 0.9.29 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: tuukka.pensala(a)gmail.com Target Milestone: --- In mdb_dump.c we have these instructions: /* -a: dump main DB and all subDBs * -s: dump only the named subDB * -n: use NOSUBDIR flag on env_open * -p: use printable characters * -f: write to file instead of stdout * -V: print version and exit * (default) dump only the main DB */ However, contrary to the description, the option -a does not dump the main DB. With argument -a "dumpit(..)" is called for the named databases, but not for the unnamed one. With the current behavior, if the data store contains subDBs and has user-added data in the main DB, there seems to be no way to dump all of it at once using mdb_dump. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9735] New: [PATCH] try hard to find free space if database cannot grow

https://bugs.openldap.org/show_bug.cgi?id=9735 Issue ID: 9735 Summary: [PATCH] try hard to find free space if database cannot grow Product: LMDB Version: 0.9.24 Hardware: All OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: libor.peltan(a)nic.cz Target Milestone: --- Created attachment 851 --> https://bugs.openldap.org/attachment.cgi?id=851&action=edit Patch fixing the issue "try hard to find free space if database cannot grow" Note: - the issue is the same in version 0.9.70 (git) Situation: - the database had already grown to its limit (mapsize) in the past - overflow pages are used heavily as stored values are usually several pages long - free space got fragmented Problem: - attempt to insert new value results in MDB_MAP_FULL despite there is free space available Cause: there is a heursitic in mdb_page_alloc() that gives up searching for free space chunk if this would take too much time. This is useful when the database can still grow, as it balances performance with space usage. However, if the database can no longer grow, it prevents inserting new values. Solution: detect early on in mdb_page_alloc() if the database can grow, and if not, let it try hard to search for free space.

[Issue 10064] New: Add modrdn support for Cft_Misc entries
by openldap-its＠openldap.org 26 Sep '23

26 Sep '23

https://bugs.openldap.org/show_bug.cgi?id=10064 Issue ID: 10064 Summary: Add modrdn support for Cft_Misc entries Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Currently in cn=config, there is some special handling to maintain overlays/dbs entries to allow list-like management. All module defined entries are marked Cft_Misc and this behaviour is not available there. It boils down to allowing the module to screen rename/renumber requests and having bconfig defer to that callback if it's defined. Use-case: policy selection rules in ITS#9343 would benefit from being managed this way rather than having to reparse a long line every time a rule is adjusted. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10087] New: slapd crashes with core dump Assertion `!LDAP_BACK_CONN_TAINTED( lc )

https://bugs.openldap.org/show_bug.cgi?id=10087 Issue ID: 10087 Summary: slapd crashes with core dump Assertion `!LDAP_BACK_CONN_TAINTED( lc ) Product: OpenLDAP Version: 2.5.15 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: rajko(a)albrecht.jetzt Target Milestone: --- The slapd daemon crashes every ten minutes with slapd: ../../../../../servers/slapd/back-ldap/bind.c:181: ldap_back_conn_delete: Assertion `!LDAP_BACK_CONN_TAINTED( lc )' failed. Aborted (core dumped) I searched around for multiple days but didn't find any solution to this problem. I have the same problem with 2.6.x versions. It is configured to act as caching ldap, while multiple hundred systems contact it. The error message is completely useless for sysadmins because they don't understand what this means for them (as said, asking search engines gives no answers) nor I don't know if - and if so how - I can fix this with configuration. I don't see if this message is talking about the connection to the upstream ldap server or if this is the connection from a client to the caching (and crashing) daemon. First setup was plain on a linux machine, now runnig inside docker environment so the service is restarted after the crash. This is of course not a nice solution. And it looks like the same like #4390 which is marked as "not solved". At least a description what this error messages means would be very helpful incl. how a workaround could look like (increasing timeouts, increase/decrease a socket pool or whatever). Currently the slapd is nearly useless when using it as a caching ldap with high load. Any hints? -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10096] New: SIGSEGV in try_read1msg() while using referrals with AD
by openldap-its＠openldap.org 18 Sep '23

https://bugs.openldap.org/show_bug.cgi?id=10096 Issue ID: 10096 Summary: SIGSEGV in try_read1msg() while using referrals with AD Product: OpenLDAP Version: 2.6.2 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: simon.pichugin(a)gmail.com Target Milestone: --- The double free happens during a referral chasing with AD. SSSD usage Background (But I think the issue can happen even without SSSD): Referral chasing with AD and Kerberos based GSSAPI/GSS-SPNEGO authentication will never work based in the fact that AD will return domain names instead of the names of AD DC in the referral. That with with 'id_provider = ad' (SSSD setting) there is 'ldap_referrals = false' as default. For 'id_provider = ldap' we expect a generic LDAP server (not AD) which returns proper referrals with fully-qualified hostname or where is simple bind is used, either anonymous or with bind DN and password (which is expected to be the same on all involved LDAP servers and which is not the case with AD since the AD DC from a different domain won't know the given bind DN). So the issue is an unusual one, but still, as it's a crash, I think it deserves a look at.
