(ITS#7712) Lock ordering problem in libldap/abandon.c

by ebackes＠symas.com

Full_Name: Emily Backes Version: RE24/HEAD OS: any URL: Submission from: (NULL) (98.155.30.248) libldap has a lock ordering problem in do_abandon in libldap/abandon.c; do_abandon always runs in locked req_mutex context, but one of the cases acquires conn_mutex for the ldap_free_connection() call. The function is always called with that mutex held, but has several non-local exits and other difficulties with refactoring the problem away, so the clearest solutions seems to be dropping and retrieving the req_mutex while messing with the conn_mutex. Patch incoming.

It is not for asking questions about how to use the software. Usage questions should be asked via the openldap-technical(a)openldap.org mailing list.

(ITS#7711) Cannot include the radius.schema

by psam1219＠hotmail.com

Full_Name: Don Version: slapd 2.4.23 OS: RHEL 6.3 x64 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (58.213.47.66) There is a slapd server ,and there is a freeradius server . I was following these steps . A.Copy example schema file (openldap.schema)from freeradius server. scp RADIUSSERVER:/usr/share/doc/freeradius-2.1.12/examples/openldap.schema ./freeradius.schema B.Include the file to slapd.conf . include /etc/openldap/schema/freeradius.schema C.restart slapd server service slapd restart D.When I tried to add the ldif file to create entries , this error come out . [root@RAC1 test]# ldapadd -f test.ldif -x -D "cn=Manager,dc=txldomain,dc=com" -w taxili888 adding new entry "cn=students,ou=profiles,ou=radius,dc=txldomain,dc=com" ldap_add: Invalid syntax (21) additional info: objectclass: value #0 invalid per syntax E.Then I checked the ObjectClasses from a Web UI £šphpLDAPadmin£©, I cann't see radiusprofile on the list table . I think the problem is failure of adding radius's scheme ,but I don't know why and how to solve this . Thank you for your time to check this issue .

(ITS#7710) contextCSN values not updated by internal non-replicated ops

by michael＠stroeder.com

Full_Name: Version: 2.4.36 OS: URL: Submission from: (NULL) (2001:8d8:1fe:7:d6be:d9ff:fe09:1b7c) Configuration: - MMR with 3 nodes and normal syncrepl. - slapo-memberof used to populate/update attribute 'memberOf' in user entries. If a group entry is modified and slapo-memberof updates the attribute 'memberOf' in the member's entry the contextCSN value of the server where the LDAP request was sent to is not updated on the other MMR replicas. All changes are correctly done though. After restart contextCSN values are all the same on all MMR replicas.

(ITS#7709) mdb back-end segfaults sporadically with paged searches

by openldap＠semyon.org

Full_Name: Semyon Chaichenets Version: 2.4.36 OS: Linux 3.2.0-51-generic #77-Ubuntu SMP Wed Jul 24 20:18:19 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (129.128.11.113) We have an issue whereby a paged-search operation causes slapd to segfault. At this point, I can only reproduce the issue on our production data - for which I cannot share coredumps. I am working on isolating the issue but would appreciate any help from openLDAP developers. The issue is triggered by the following search: ldapsearch -H ldap://ldaphost -b 'ou=people,dc=our,dc=org' -x -E pr=126/noprompt '(uid=m*)' We have ~59k entries starting matching uid=m*; the issue occurs unpredictably in the sense that it may or may not happen for filters matching other sets, but it can be reproduced reliably for any given filter/page size combination. On our setup, I could reproduce it for page-sizes 81,84,87,96,112,114,116,126. The issue is specific to back-mdb; backtrace points to dn2id.c: #0 0x00007f6d6a5ea6a1 in mdb_idscopes (op=0x7f695c110df0, isc=0x7f69692ca670) at ../../../../../servers/slapd/back-mdb/dn2id.c:738 #1 0x00007f6d6a5e399b in mdb_search (op=0x7f695c110df0, rs=0x7f69692dba00) at ../../../../../servers/slapd/back-mdb/search.c:747 [..] I would greatly appreciate any help you could give me with this problem.
