(ITS#5401) slapd crashes in mirrormode
by ali.pouya＠free.fr 03 Mar '08

03 Mar '08

Full_Name: Ali Pouya Version: 2.4.8 OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (145.242.11.4) Hi, I am testing OpenLdap 2.4.8 in mirrormode. I have two mirror servers (A, and B) synchronized in SearchAndPersist mode with a retry interval of 10 seconds : retry="10 +". An injector writes data to A. The data is replicated in B. But this server UNBINDs then reBINDs to A every 10 seconds ! This continues until slapd on A crashes with a SIGIOT. More investigation in the slapd log shows that the crash is caused by the losing of the client syncrepl connection coming from B ! If instead of B I configure an ordinary replica everything is OK. I think there are two distinct problems : 1) Contrarily to an ordinary replica, a mirror ends the persistent search, 2) slapd crashes (very scarcely) after losing the client syncrepl connection to which it was going to send data. Below you find the backtrace after slapd crash. See also more protocol details after the backtrace. If required I can send any detailed information about my configurations. Thanks for your help Best Regards Ali ============================ (gdb) bt #0 0x009b47a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0x00138815 in raise () from /lib/tls/libc.so.6 #2 0x0013a279 in abort () from /lib/tls/libc.so.6 #3 0x00131d91 in __assert_fail () from /lib/tls/libc.so.6 #4 0x0805ecb2 in connection_state_closing (c=0xa272585c) at connection.c:680 #5 0x0806c444 in send_ldap_ber (conn=0xa272585c, ber=0x9f7f3c00) at result.c:153 #6 0x0806f192 in slap_send_search_entry (op=0x9f7f3f50, rs=0x9f7f3de0) at result.c:1187 #7 0x08134038 in syncprov_qtask (ctx=0x9f7f4210, arg=0x8e21498) at syncprov.c:809 #8 0x081472df in ldap_int_thread_pool_wrapper (xpool=0x8cbf880) at tpool.c:625 #9 0x00a4e3cc in start_thread () from /lib/tls/libpthread.so.0 #10 0x001da1ae in clone () from /lib/tls/libc.so.6 ============================ More protocol details : 1) As an answer to the SearchAndPersist Request, A sends to B an LDAP message [OPERATION 25] (which I do not know). But this message is not sent to an ordinary replica. 2) I also noticed that after sending UNBIND, B sends a [FIN, ACK] TCP packet. As A does not ack this packet B sends a [RST, ACK] packet 30 micro-seconds later.

ITS#5145 [Fwd: Corrections for the autogroup README]
by postmaster＠altkom.pl 03 Mar '08

-------- Original Message -------- Subject: Corrections for the autogroup README Date: Mon, 03 Mar 2008 11:48:16 +0100 From: Aleksander Adamowski <aleksander.adamowski(a)altkom.pl> Reply-To: postmaster(a)altkom.pl To: hyc(a)symas.com Hi! I'd like to add some grammatical corrections to the README file for the autogroup contrib module: http://www.openldap.org/devel/cvsweb.cgi/~checkout~/contrib/slapd-modules/a… The description section should read: DESCRIPTION The autogroup overlay allows automated updates of group memberships which meet the requirements of any filter contained in the group definition. The filters are built from the LDAP URI-valued attributes. Any time an object is added/deleted/updated, it is tested for compliance with the filters, and its membership in autogroups is accordingly updated. For searches and compares it behaves like a static group. -- Aleksander Adamowski Administrator systemów korporacyjnych; Instruktor Altkom Akademia S.A. http://www.altkom.pl Warszawa, ul.

Technically, I note it's skipped by syn_schema_info() because it has no validator (like many other known syntaxes). I don't recall the reason of this behavior, though. Perhaps it could be relaxed. p.

This was introduced to be able to honor the "disclose" privilege (or, at least, in conjunction with code that is used to honore the "disclose" privilege). The man page is erroneous in stating that this requirement and that feature were introduced in OpenLDAP 2.3: the code is indeed present in OpenLDAP 2.3, but actually #ifdef'd; it only became the default behavior in OpenLDAP 2.4. This requirement, as usual, is downgraded to "auth" when performing authc/authz related lookups. I'd take this ITS as a request to fix the documentation (indicate the change since 2.4 and not since 2.3) and to better notify the different behavior since 2.3. p. Ing.

IIRC, it's not listed because it only to be used in certain (extensible) matching rules cases and slapd(8) doesn't support any of those cases. I noticed that this came up because someone was trying to use this syntax an attribute description. That attribute description is likely bogus.

As soon as one is planned, if ever. I can't say anything right now, since this issue is not a showstopper, and 2.3.41 has just been released. Unless 2.4 becomes stable any soon, there'll probably be another 2.3 at some point. p. Ing.

ITS#5396
by ecizaguirre＠gmv.com 29 Feb '08

Another update about this problem. Connections between slpad and the remote active directory servers remains in ESTABLISHED state for a long time and changes to CLOSE_WAIT state in the slapd server. In the active directory servers the connections then changes to FIN_WAIT_2, so it seems the slapd server is not sending the FIN packet to close the socket. Cheers. Eduardo ________________________________ De: Eduardo Izaguirre Pazos Enviado el: jueves, 28 de febrero de 2008 13:21 Para: 'openldap-its(a)openldap.org' Asunto: ITS#5396 An update about the case, the problem seems to be related with the connections which remains in CLOSE_WAIT state, as an example: [root@metaldap openldap]# netstat -an | grep -i close | wc -l 11361 all these connections are to the remote ldap servers.
