But I've had two recent crashes so I figured I'd send the details through. Thanks again, Jim, for this very valuable information.

Bug#484235: [Pkg-samba-maint] Bug#484235: panic-action called for /usr/sbin/winbindd
Last night I upgraded to the following packages: ii ldap-utils 2.4.10-2+lenny1 OpenLDAP utilities ii libldap-2.4-2 2.4.10-2+lenny1 OpenLDAP libraries ii libwbclient02:3.2.0-4 client library for interfacing with winbind service ii samba 2:3.2.0-4 a LanManager-like file and printer server for Unix ii samba-common2:3.2.0-4 Samba common files used by both the server and the client ii samba-dbg 2:3.2.0-4 Samba debugging symbols ii samba-doc 2:3.2.0-4 Samba documentation ii smbclient 2:3.2.0-4 a LanManager-like simple client for Unix ii winbind 2:3.2.0-4 service to resolve user and group information from Windows NT servers Unrelated, but I figure I'll mention it. The upgrade from 3.0.x to 3.2.x bit me. We have a perl script that returns a list of members of a group as follows: my (undef, undef, $gid, $members) = getgrnam $group; For Samba 3.0.x $members contained a space separated list of names (eg user1 user2 user3). Now with Samba 3.2.x it contains the Windows domain name as well (eg DOMAIN\user1 DOMAIN\user2 DOMAIN\user3). It's fine, I just had to change the code to suit, but it caused some problems for a while. Is that something that needs to be mentioned somewhere in the NEWS.Debian file or something like that? Anyway. On to the problem at hand. The panics are not fixed. Here is the new panic dump from version 3.2.0 as supplied by the panic-action script: [Thread debugging using libthread_db enabled] [New Thread 0xb7adc6d0 (LWP 6827)] 0xb7cd66be in waitpid () from /lib/libc.so.6 #0 0xb7cd66be in waitpid () from /lib/libc.so.6 #1 0xb7c7e02e in ??

And essentially, this points to a failure in ldap_search_ext_s(), because this function isn't returning an error but is returning a NULL res value which then fails this assert in ldap_parse_result(). I'm not sure yet how that could happen; perhaps some more logs will make it clearer. The installation of version 2.4.10-2 of the LDAP libraries hasn't fixed the problem.

Jim Barber wrote: There seems to be gaps in the timestamps in these files for some reason. Oh, I've found the problem with the logs. I had 'max log size = 1000' defined in /etc/samba/smb.conf (the default value). The log.winbind file is reaching this size every hour with the debug level 4 turned on. So it gets cycled to log.winbind.old replacing the previous .old file and so losing the logging info. I've increased this value significantly, so hopefully for the next crash I'll have some useful information.

I've now installed the newer ldap packages like so: ii ldap-utils 2.4.10-2OpenLDAP utilities ii libldap-2.4-2 2.4.10-2OpenLDAP libraries I've also added the following to the /etc/samba/smb.conf file and restarted samba.

So here is what I've found with the default log level (which I guess is 0?) winbindd: error.c:272: ldap_parse_result: Assertion `r != ((void *)0)' failed. Aha, well, that handily answers the question of which of the three assert statements in ldap_parse_result() is being hit. And essentially, this points to a failure in ldap_search_ext_s(), because this function isn't returning an error but is returning a NULL res value which then fails this assert in ldap_parse_result(). I'm not sure yet how that could happen; perhaps some more logs will make it clearer. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

Hi. I've upgraded to the new version and also installed the samba-dbg package this time. No changes were made to the Samba configuration. The LDAP libraries were also updated. I still experience crashes.

I've got a couple more stack dumps from today as well that look a little different. Is it worth sending them through as well? Once if very similar except for slight variations in a number of the hex values. But at step #18 a different path down the functions calls happens. So I'll paste that. Replace steps #18 to #20 from the previous dump with: #18 0x080b89ef in async_request_fail (state=0x8374cf0) at nsswitch/winbindd_dual.c:208 #19 0x0808bc7a in rw_callback (event=0x834f1e0, flags=1) at nsswitch/winbindd.c:389 #20 0x0808c6c9 in main (argc=) at nsswitch/winbindd.c:854 I've also got another one where at step #14 it's called query_user_list instead of just query_user. That walks a different list of functions, but still finally dies at nsswitch/winbindd.c:854 Let me know if I should send full stack dumps of both or not.

Quoting Jim Barber ([EMAIL PROTECTED]): I've got a couple more stack dumps from today as well that look a little different. Is it worth sending them through as well? Any bit of information might be worthy..:-) Steve (Langasek) I think you're the one who can analyze that and decide what to do with it (upstream or not, belonging to another package, not having a clue, etc.). signature.asc Description: Digital signature

severity 484235 important thanks Quoting root ([EMAIL PROTECTED]): Package: winbind Version: 1:3.0.28a-3 Severity: critical Justification: breaks unrelated software Sorry, that's overestimated. winbind and samba works for dozens of users all around so that bug does not deserve that severity. We are using winbind to authenticate users to the system for various services. The winbind daemon seems to crash many times a day. At the moment I have a cron job that restarts winbind and samba every time as crash has been detected to minimise the impact on the system. This happens on two separate servers that we run winbind on. They are both located in different networks in different Active Directory environments. I'll just report on one of the hosts that is more active and suffers from the crashes more frequently. Output from 'testparm -s /etc/samba/smb.conf' is as follows: The above seems to suggest something going wrong with LDAP? I have the latest libraries for LDAP in the testing distribution installed. Output from 'dpkg --list | grep ldap' is: ii ldap-utils 2.4.7-6.3 OpenLDAP utilities ii libldap-2.4-2 2.4.7-6.3 OpenLDAP libraries Please at least try upgrading to 3.0.30 as soon as it enters testing (as you seem to be using testing). I have no idea if that may fix the problem or not, though. signature.asc Description: Digital signature

Christian Perrier wrote: Severity: critical Justification: breaks unrelated software Sorry, that's overestimated. Okay sorry about the overstated severity. I was going to put it in as 'normal' but I followed the descriptions from reportbug which mislead me. When this breaks, packages like exim4, squid, and courier-imap break because the users can't authenticate. Please at least try upgrading to 3.0.30 as soon as it enters testing (as you seem to be using testing). I have no idea if that may fix the problem or not, though. Okay. I think the problem happened earlier, but it took me a while to report it. ie. It happened in 3.0.27 as well and maybe even .26? I couldn't tell you if it corresponds with an upgrade to Samba or LDAP. When .30 comes along I'll install the samba-dbg package so that I can get a better stack dump.
