(ITS#8088) slapd man pages get installed when --disable-slapd is specified
by quanah＠openldap.org 24 Mar '15

24 Mar '15

Full_Name: Quanah Gibson-Mount Version: RE24 OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.64.214) When only building out the client libraries (--disable-slapd), make install goes ahead and installs the man pages related to slapd, which should be skipped in this case.

(ITS#8087) Segmentation fault in MDB at idl.c:91 using searches

Full_Name: Francisco Garnelo Version: slapd 2.4.40 OS: FreeBSD 10.1-STABLE URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (194.237.142.21) Hi, when I try to access with a LDAP browser (Apache DS) and the browser begin to enumerate the items in differents branches, the server crashes; this not takes more than 30 seconds from last restart. I experimented a similar issue with SLES 12(if not it is the same) and openldap 2.4.40 (from suse repositories) version, but in this system I could not take evidences. The database has more than 3GB of size and MDB is configured to support 100GB as the maximum size. The same databa w works fine ining BDB using an old openldap version. ############# # Versions: # ############# root@XXXX:/usr/local/etc/openldap # /usr/local/libexec/slapd -VVV @(#) $OpenLDAP: slapd 2.4.40 (Mar 24 2015 17:18:46) $ root@XXXX:/usr/rtrts/net/openldap24-server/work/openldap-2.4.40/servers/slapd Included static overlays: dynlist seqmod syncprov Included static backends: config ldif relay root@xxxx:/usr/local/etc/openldap #

This one just bit us again. I know that the client should probably not be using pr at all, but the client is an Google supplied intergration application that we have little control over. Is this a problem that is going to be addressed as some point or will it be treated as a known limitation? Bill -- "We have meet the enemy and he is us." Pogo

Sounds like a ppc64 binutils bug then. You can #if 0 that definition for ppc64 if you want, since it's only a small optimization for text segment size. But if ppc64 is using standard ELF binary format, this should not be breaking. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

I'm not sure why the crash is triggered from this commit onward. The real issue seems to be the attribute usage in mdb.c: # define ESECT __attribute__ ((section("text_env"))) If ESECT is simply removed, the crash goes away. -- Jan Synacek Software Engineer, Red Hat

(ITS#8086) slapd with mdb backend crashes in id2entry
by nvoutsin＠gmail.com 20 Mar '15

Full_Name: Nikos Voutsinas Version: 2.4.40 OS: Debian URL: ftp://ftp.openldap.org/incoming/NikosVoutsinas_20-03-2015_mdb_assertion.id2… Submission from: (NULL) (5.55.167.101) slapd with an mdb backend, after some time of normal operation, may reach into a situation where you can almost predictably crash it, with a simple modify operation. Unfortunately, it is not clear, what are the exact steps that trigger the first crash, but once this happens, the pattern after is rather standard. After the initial crash, you restart slapd and you send a single modify operation on any single attribute, the operation completes successfully. You send again the same modify operation, and slapd crashes in servers/slapd/back-mdb/id2entry.c:520: mdb_opinfo_get. I know that the description doesn't say much, but I am not sure what can I do to narrow down the problem. However I managed to catch this in a log file (assertion.id2entry) with full debug flags and I hope that someone may see into this something, that I can not. The DIT and the database come from a testing system, are very small in size and I can send them if that helps. The cn=config on the other hand is rather complicated as it includes an MMR and many other options. btw the same crashes have happened in both masters. Best Regards. Nikos
