Description Roland McGrath 2010-02-26 22:40:51 UTC
Description of problem:

strip resets the EI_OSABI to zero in a file where it was ELFOSABI_LINUX (3).

Version-Release number of selected component (if applicable):
binutils-2.20.51.0.2-15.fc13.x86_64

How reproducible:
100%

Steps to Reproduce:
1.echo 'asm("foo: ret; .globl foo; .type foo,@gnu_indirect_function"); main() {}' > ifunc-strip.c; gcc -o ifunc-strip ifunc-strip.c
2.readelf -h ifunc-strip|head -2 => see an 03 in there
3.strip ifunc-strip; readelf -h ifunc-strip|head -2 => see a 0 there instead
  
Actual results:
Changed the 03 to a 00.

Expected results:
Leave the 03 an 03.

Hi Roland,

 I have created a patch which I think will address this problem.  Please could you try out the latest rawhide binutils rpm and let me know how you get on with it ?

Cheers
  Nick

Comment 2 Roland McGrath 2010-03-02 20:16:58 UTC
That does indeed fix the test case.  Seeing the patch without knowing all the code makes me wonder if this fully covers all the similar cases, i.e. EI_ABIVERSION or whatever other e_ident bytes might one day be used, e_flags, etc.  I don't have test cases for those, just wondering about preemptive fixes for the possible future.

Please put the update in F-13 too.  It's not released yet, but even so this now entails using bodhi as for F-12 et al.  But probably you should fix bug 568941 too beforehand.

This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '13'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Comment 4 Bug Zapper 2011-06-27 15:03:23 UTC
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
