Bug 210982 – IndexError: list index out of range from rlpkg (part of policycoreutils) while Scanning for shared libraries during converting to SELinux

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description gtl4407 2008-02-21 14:58:47 UTC]

I am converting an installation to SELinux following the guide at: http://www.gentoo.org/proj/en/hardened/selinux/selinux-handbook.xml

Things have been going well until I try and do the filesystem labeling. Here is a transcript of the problem.

Code:
rlpkg -a -r

Created attachment 144473 [details]
debug rlpkg

[Comment 2 Chris PeBenito (RETIRED) 2008-02-24 01:57:06 UTC]

Can you try the attached rlpkg, it has additional debug info as I can't reproduce this.

Hi Pebenito

I followed your demand and here is the output:

hypherserv ~ # ./rlpkg_debug -r -t
Scanning for shared libraries with text relocations...
0 libraries with text relocations, 0 not relabeled.
Scanning for PIE binaries with text relocations...
0 binaries with text relocations detected.
hypherserv ~ # rlpkg -t -r

  File "/usr/sbin/rlpkg", line 164, in relabel_textrel_shlib
    if ctx[2] in textrel_ok_relabelfrom:
IndexError: list index out of range

As you can see, the rlpkg(_debug) attached from you to this bug doesn't break or show something special...

[Comment 4 Chris PeBenito (RETIRED) 2008-10-03 11:23:40 UTC]

should be fixed in policycoreutils 2.0
