Probably you mean before setuid(); chroot has nothing to do with the identity a process is running as. > The before-chroot creation of the database is the bug. The database is opened (and thus created, if it doesn't exist) only **after** setuid(). In fact, setuid() (and chroot() occur **before** even reading the configuration file. If it were like you say, the files would have been created **before** even knowing in which directory they should be located. > When this happens ldap-delete operations fail with: > ldap_delete: Internal (implementation specific) error (80) > additional info: entry index delete failed Probably you unintentionally performed some operation that created the files before starting slapd. p.

(ITS#5166) Wrong DBD's database permissions when slapd starts
by pedrorandrade＠gmail.com 03 Oct '07

03 Oct '07

Full_Name: Pedro RA Version: 2.3.30-5 OS: Debian 4.1.1-21 URL: Submission from: (NULL) (85.139.209.115) When slapd is starting, and no database exists, slapd creates a new one with the wrong permissions (user:root, group:root) This probably is caused by slapd creating the database before chroot. The before-chroot creation of the database is the bug. When this happens ldap-delete operations fail with: ldap_delete: Internal (implementation specific) error (80) additional info: entry index delete failed A working workaround is setting the right permissions to DBD files. In my system (Debian Etch 4.1.1-21, openldap 2.3.30-5) the command is: chmod -r openldap:openldap /var/lib/ldap

Issues with syncrepl and mirrormode
by Pierangelo Masarati 03 Oct '07

03 Oct '07

We're experiencing some strange issues with mirrormode; I don't have the whole picture at hand, right now, and I haven't been able to create the issue in a repeatable manner, however it happens regularly. The scenario is: 2 mirror-mode servers, each with 2 databases, plus back-config, replicated using syncrepl refreshAndPersist. We notice occasional sigsegv, and we could finally get a core dump, which contains #0 0x080e0e6f in compare_csns (sc1=0x33a96a80, sc2=0x33a96aa0, which=0x33a9682c) at ../../../servers/slapd/syncrepl.c:665 665 for (j=0; !BER_BVISNULL( &sc2->ctxcsn[j] ); j++) { (gdb) bt full #0 0x080e0e6f in compare_csns (sc1=0x33a96a80, sc2=0x33a96aa0, which=0x33a9682c) at ../../../servers/slapd/syncrepl.c:665 i = 0 j = 0 match = 0 text = 0x80e0e1a "\201� #1 0x080e7385 in do_syncrep2 (op=0x33a96d40, si=0x919c548) at ../../../servers/slapd/syncrepl.c:990 i = Variable "i" is not available.

Mi first question is: is "rid=004,sid=000,csn=" a legitimate cookie? If it is, the code must account for (not) calling compare_csns() when the ctxcsn member of either struct sync_cookie is NULL. In that case, I suggest the patch Index: servers/slapd/syncrepl.c =================================================================== RCS file: /repo/OpenLDAP/pkg/ldap/servers/slapd/syncrepl.c,v retrieving revision 1.361 diff -u -r1.361 syncrepl.c --- servers/slapd/syncrepl.c 29 Sep 2007 14:11:28 -0000 1.361 +++ servers/slapd/syncrepl.c 1 Oct 2007 12:25:05 -0000 @@ -985,7 +985,13 @@ if ( !BER_BVISNULL( &syncCookie.octet_str ) ) { slap_parse_sync_cookie( &syncCookie, NULL ); - compare_csns( &syncCookie_req, &syncCookie, &m ); + m = 0; + if ( syncCookie.ctxcsn ) { + compare_csns( &syncCookie_req, &syncCookie, &m ); + } else { + /* otherwise it would be dereferenced few lines below */ + assert( !refreshDeletes ); + } } } if ( ber_peek_tag( ber, &len ) == So the second question, assuming the above cookie is legitimate, would be: is it legitimate that the above cookie will only occur with refreshDelete unset? p.

I mainly wanted the db_stat information to make sure there were no held writelocks, which it is clear is not the case. I find I do have another pstack output from this same type of hang with another client at: <http://bugzilla.zimbra.com/attachment.cgi?id=5896> I'm working on getting the slapd.conf in question, but I believe the only overlays affecting the BDB backend are syncprov and accesslog. --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration

(ITS#5165) strtoul(3) might be used incorrectly
by ando＠sys-net.it 02 Oct '07

02 Oct '07

Full_Name: Pierangelo Masarati Version: HEAD/re24/re23 OS: irrelevant URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (81.72.89.40) Submitted by: ando Occasionally, strtoul(3) is used in slapd(8) to parse integers that are expected to be unsigned. It seems that strtoul(3) is used under the assumption that it will fail if a negative number is encountered. This is not the case; in fact, by design, negative numbers are read as positive, and negated. If negative numbers are not allowed, strtol(3) should be used instead, and the value should be checked (or the string should be checked for '-' before calling strtoul(3). p.

This of course shouldn't be possible since one of those threads must already own it. We really need to have gdb access here to inspect the state of the mutex and see which thread is the owner, then figure out why it's trying to lock it again. In OpenLDAP 2.3 this pretty much means that some operation locked the mutex and somehow completed without unlocking it, i.e. completed without going thru the accesslog response callback. This has nothing to do with BDB so db_stat isn't relevant here. It's about the accesslog overlay and any other overlays that may be manipulating the callback stack, so your slapd.conf is more relevant here. -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
