Bug 30937 – fetchipac segfaults

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Marco Lange 2003-10-11 16:49:50 UTC]

I just installed net-analyzer/ipac-ng-1.27_p1 on a server for traffic
accounting. When I start it via "/etc/init.d/ipac-ng start" it prints

/sbin/runscript.sh: line 526:  3069 Segmentation fault      /usr/sbin/fetchipac -S
/sbin/runscript.sh: line 526:  3070 Segmentation fault      /usr/sbin/fetchipac

When I execute fetchipac on the console it also prints "Segmentation fault".      

Reproducible: Always
Steps to Reproduce:
1. Install ipac-ng
2. Execute fetchipac oder /etc/init.d/ipac-ng start

Actual Results:  
See in the "Details" section.

I have the same problem on 2 machines here.
The problem occurs on line 1003 of fetchipac.c with a call to strcasecmp

  if (strcasecmp((*smp)->name, storage_method_name) == 0)

storage_method_name is initially a null pointer, hence the segfault. Reading
the ipac mailing list though no one else seems to be having this problem.
Has this behaviour changed in later glibc's?

this happens when you dont have config files

1.27_p1-r1 installs default config files for you now
