(ITS#7837) slapd seg faults in slapo-rwm

14 Apr '14

Full_Name: Michael Ströder Version: 2.4.39 with patches OS: URL: Submission from: (NULL) (212.227.35.93) slapd occasionally seg faults. We can't reproduce it with a certain configuration. This is a custom Debian Wheezy package based on OpenLDAP 2.4.39 linked against OpenSSL under a separate prefix. slapo-rwm is patched according to ITS#7723 but I can't tell whether it's related to ITS#7723 or not. Hence the separate ITS. master commit for the reference counting patch used: http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commit;h=5f524c44… Here's the stack trace (obfuscated filter and search base): Program terminated with signal 11, Segmentation fault. #0 0x00007f8ca2d8a29d in ??

(ITS#7836) Incorrect behavior with problematic LDAP server
by tarkhil＠over.ru 14 Apr '14

14 Apr '14

Full_Name: Alex Povolotsky Version: 2.4.36 OS: FreeBSD 9.2 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (89.178.228.111) Hello I'm using failover setup for my LDAP authentication === ldap.conf === BASE dc=org,dc=ru URI ldap://serv1 ldap://serv2 TIMEOUT 3 NETWORK_TIMEOUT 3 TIMELIMIT 3 SUDOERS_BASE ou=sudoers,dc= nss_base_passwd o=infotel,dc= pam_filter objectClass=posixAccount === Today, serv1 failed, become unaccessible but not down. I can connect to LDAP port, but server closes the connection immediately. In this case, second URI does not work. Any ldap tool fails ("Cannot connect to server"). Shutting down interface helped, but I suppose that there must be an option to try second URI on such an error.

(ITS#7834) MDB_MULTIPLE can insert multiple keys
by h.b.furuseth＠usit.uio.no 12 Apr '14

12 Apr '14

Full_Name: Hallvard B Furuseth Version: LMDB 0.9.11 OS: Linux x86_64 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (81.191.45.35) Submitted by: hallvard mdb_cursor_put(,new key, multiple data items, MDB_MULTIPLE) inserts several identical keys as well as multiple data items. Broken since 0.9.10 by 4c8f57615c5ca7b014c038e59c1045182e74f5ad. OpenLDAP is not affected, since it no longer uses MDB_MULTIPLE. Root cause: mdb_cursor_put() does not reset the 'insert' flag when looping through MDB_MULTIPLE. Recently it uses that flag to decode whether to delete the old key before re-inserting it. Also MDB_MULTIPLE breaks MDB_db.md_entries so mdb_stat() reports the wrong number of entries. This was always so. The 'insert' flag also affects cursor tracking. I have not checked how. Fix: Reset 'insert' before looping, and move setting C_INITIALIZED at 'done:' before that again. This should make MDB_MULTIPLE behave like a sequence of put()s, except it does not repeat spill/touch.

I took a brief look at it. The config file syntax seems a bit awkward, how do you distinguish a new class name from an existing reserved keyword?

Hi, This ITS says "fixed in master" and appears to be in 2.5 as well. However 2.4 seems to still be affected. Is this fix a candidate for 2.4? thanks, Ryan
