(ITS#8388) broken schema after replacing objectClass
by lessmian2＠o2.pl 16 Mar '16

16 Mar '16

Full_Name: Tomasz Le&#347;niewski Version: 2.4.44 OS: ubuntu URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (85.128.131.1) accidentally i broke my openldap schema when i've changed one of objectClass definitions. For example i have two objectClasses and one is a parent for second: olcObjectClasses: {0}( 1.2.3.4 NAME 'foo' DESC '' SUP top AUXILIARY X-ORIGIN 'user defined' ) olcObjectClasses: {1}( 1.2.3.5 NAME 'bar' DESC '' SUP foo AUXILIARY X-ORIGIN 'user defined' ) I've changed definition of foo - i've delete this object and (my mistake) put it without any number at bottom of all classes: dn: cn=config changetype: modify delete: olcObjectClasses olcObjectClasses: {0} - add: olcObjectClasses olcObjectClasses: ( 1.2.3.4 NAME 'foo' DESC '' SUP top AUXILIARY X-ORIGIN 'user defined' ) So i have now class bar at top of schema and foo at bottom. After restart slapd won't start. Slapcat says: 56d4678f olcObjectClasses: value #5 olcObjectClasses: ObjectClass not found: "foo" 56d4678f config error processing cn=config: olcObjectClasses: ObjectClass not found: "foo" slapcat: bad configuration file! Should slapd allow to make something that could break schema? I thought that there are some constraints that not allow to remove objectClass which is parent for another class.

However, I do not want to engage in a political discussion, particularly on the matter that is beyond my control. It is also out of topic, as the bug discussed here was in libldap code, and not in GnuTLS. I would like to again thank Howard for his work on this bug and coming up with a working fix very quickly. Unless any new issue related to this bug or the fix comes to light, I think we can consider the matter closed. Maciej Puzio

(ITS#8387) online olcDbConfig change fails with syncprov
by ryan＠openldap.org 14 Mar '16

14 Mar '16

Full_Name: Ryan Tandy Version: 2.4, master OS: Debian URL: Submission from: (NULL) (24.68.37.4) Submitted by: ryan Forwarding from a Debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816294 Configure a BDB or HDB database with syncprov: dn: olcDatabase={1}hdb,cn=config objectClass: olcHdbConfig olcDbDirectory: data olcSuffix: dc=example,dc=comD%D dn: olcOverlay={0}syncprov,olcDatabase={1}hdb,cn=config objectClass: olcSyncProvConfig perform some kind of modification to the database (so that a syncprov checkpoint is pending), and perform an online olcDbConfig change that reopens the database. dn: olcDatabase={1}hdb,cn=config changetype: modify replace: olcDbConfig olcDbConfig: set_cachesize 1 0 1 Reopening the database fails: 56e76e17 bdb(dc=example,dc=com): BDB4511 Error: closing the transaction region with active transactions 56e76e17 bdb_db_close: database "dc=example,dc=com": close failed: Invalid argument (22) and slapd crashes shortly after, when it tries to syncprov_checkpoint while the database is already gone. What appears to be happening is that "ctx" is different between bdb_reader_get and bdb_reader_flush in this case. During a normal slapd startup and shutdown: (gdb) thread apply all frame Thread 1 (Thread 0x7ffff7fed700 (LWP 21570)): #0 hdb_reader_get (op=0x7fffffffd8d0, env=0xa93fa0, txn=0x7fffffffd610) at cache.c:1666 1666 if ( !ctx ) { (gdb) p ctx $1 = (void *) 0x8b34a0 <ldap_int_main_thrctx> [ ... killall slapd ... ] (gdb) thread apply all frame Thread 1 (Thread 0x7ffff7fed700 (LWP 21570)): #0 hdb_reader_flush (env=0xa93fa0) at cache.c:1643 1643 if ( !ldap_pvt_thread_pool_getkey( ctx, env, &data, NULL ) ) { (gdb) p ctx $2 = (void *) 0x8b34a0 <ldap_int_main_thrctx> In this case, the readers are cleared correctly. Another startup, this time the hdb_db_close is triggered by performing an olcDbConfig change: (gdb) thread apply all frame Thread 1 (Thread 0x7ffff7fed700 (LWP 21624)): #0 hdb_reader_get (op=0x7fffffffd8d0, env=0xa93fa0, txn=0x7fffffffd610) at cache.c:1666 1666 if ( !ctx ) { (gd2929 p ctx $1 = (void *) 0x8b34a0 <ldap_int_main_thrctx> [ ... ldapmodify ... ] (gdb) thread apply all frame Thread 3 (Thread 0x7ffff362e700 (LWP 21633)): #0 hdb_reader_flush (env=0xa93fa0) at cache.c:1643 1643 if ( !ldap_pvt_thread_pool_getkey( ctx, env, &data, NULL ) ) { Thread 2 (Thread 0x7ffff3e2f700 (LWP 21631)): #0 0x00007ffff732d4d3 in epoll_wait () at ../sysdeps/unix/syscall-template.S:84 84 ../sysdeps/unix/syscall-template.S: No such file or directory. Thread 1 (Thread 0x7ffff7fed700 (LWP 21624)): #0 0x00007ffff75f06dd in pthread_join (threadid=140737285125888, thread_return=0x0) at pthread_join.c:90 90 pthread_join.c: No such file or directory. (gdb) p ctx $2 = (void *) 0x7ffff362dbf0 This time we have a different ctx, so the readers are not cleared. This when we get to db->close there is still an active txn. The comment "free up any keys used by the main thread" seems to assume bdb_reader_flush will be called on the main thread only.

The Debian/Ubuntu maintainers are quite aware of the problems with using GnuTLS, and maintain they cannot use OpenSSL due to licensing issues, despite the fact every other major distribution uses OpenSSL (except RHEL, which switched to MozNSS which resulted in much disaster, and is likely going to switch back to OpenSSL). There is no reason you cannot use OpenSSL, regardless of what Debian/Ubuntu's broken decisions are. --Quanah -- Quanah Gibson-Mount Platform Architect Zimbra, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration A division of Synacor, Inc
