Bug 90825 – after upgrade to glibc-2.3.4.20041102-r1 samba crashes

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description samuele assirelli 2005-04-29 00:16:38 UTC]

After upgrade to glibc-2.3.4.20041102-r1 samba gives a lot of problems. When user manager for domains is opened the admins can do nothing and a "denied access" error is given. The users can login into domain but we have random errors of denied access to shared resources (not on samba server but to a member server).
If we downgrade to glibc-20040808-r1 these problems desappear.

Reproducible: Sometimes
Steps to Reproduce:
1. upgrade to glibc-2.3.4.20041102-r1
2. restart samba

Actual Results:  
User can login but "user manager for domains" and "server manager" are useless.

We use samba with openldap-2.2.19 backend with smbldap-tools-0.8.6.

Inspecting the samba log i found this:

The log was taken on another server in the testing environment, where i
trasferred a tar.bz2 archive of the entire distribution. After glibc upgrade the
problems are the same.

I don't know for sure if what I am seeing is related, however, this appears to be just since I upgraded glibc.  I am going to recompile w/o stack protector.

robbat2: you recognize these ?  they look familiar ...

[Comment 3 Robin Johnson 2005-04-30 02:30:22 UTC]

vapier: nope, not familar at all. I haven't seen any problems with Samba up to 3.0.10 (I'm not running anything newer), and glibc all the way up to 2.3.5. I'm also on a pure LDAP backend.

[Comment 4 samuele assirelli 2005-05-03 03:54:06 UTC]

I've tried with glibc version up to 2.3.5. This is the situation:

glibc-2.3.4.20041102-r1 samba is not working
glibc-2.3.4.20050125 samba is not working
glibc-2.3.4.20050125-r1 samba is not working
glibc-2.3.5 samba is working

It seems that with glibc-2.3.5 samba is running without problems.

[Comment 5 Jeremy Huddleston (RETIRED) 2005-07-15 14:27:21 UTC]

closing as 2.3.5 is stable on x86 now...
