Description Roland McGrath 2005-04-28 23:23:43 EDT
+++ This bug was initially created as a clone of Bug #156341 +++

Description of problem:

When eu-strip writes separate debuginfo from an ET_REL object such as a kernel
module (.ko file), it doesn't fix up the relocs referring to section symbols
removed from the symbol table.

Version-Release number of selected component (if applicable):
0.106-3

How reproducible:
100%

Steps to Reproduce:
1. Install kernel-debuginfo package.
2. Try to use foo.ko.debug.
3. See bad relocs.
  
Actual results:


Expected results:


Additional info:

This is a blocker for SystemTAP.
Comment 1 Roland McGrath 2005-05-09 04:23:20 EDT
This is fixed upstream/for Fedora (Bug #156341).
Needs backport fix or perhaps just upgrade of elfutils.
Comment 2 Roland McGrath 2005-05-25 21:24:52 EDT
The RHEL4 eu-strip actually just uses the binutils objcopy/strip.
The binutils strip-to-debug works differently and the debuginfo produced should
be fine for systemtap.
Comment 3 Jay Turner 2005-06-21 14:32:13 EDT
Removing from proposed list.
Comment 4 Roland McGrath 2005-08-01 21:40:29 EDT
Turns out I was wrong.  I confused myself trying to make sense of the insane
elfutils multi-stream errata situation in RHEL.  In fact, the elfutils being
used for RHEL4 builds is the real non-stub one, and eu-strip is the real one
with this bug rather than the binutils wrapper.
Comment 10 Roland McGrath 2005-10-10 17:03:56 EDT
This is an unrelated bug.  This error message is never the failure mode of the
eu-strip issue.
Comment 11 Roland McGrath 2005-10-10 17:12:42 EDT
As long as the buildroots don't change, this is not an issue for RHEL4.
Comment 17 Roland McGrath 2006-04-20 20:11:26 EDT
0.97.1-3 should fix this.
Comment 20 Red Hat Bugzilla 2006-08-10 14:28:22 EDT
