Pratyush,

Thanks for the effort, let's cc Fedora devel list, see if we can get help from Fedora experts.

Summary the problem: Latest kexec-tools koji build in rawhide results in a wrong kexec binary, kexec load fails with something like below: R_X86_64_29 Unhandled rela relocation: R_X86_64_29

This kinds of errors usually caused by gcc unnecesarrily add options like -fexception, -fPIC, -fstack-protetor-* for building kexec purgatory which runs in kernel mode.

I filed a bug below: https://bugzilla.redhat.com/show_bug.cgi?id=1236456

Appreciate for any hints how to fix the problem.

Hi Dave,

Really not able to get whats the issue..let koji people look into..

    kexec-tools-2.0.7-11.fc23.x86_64.rpm build failed
    http://koji.fedoraproject.org/koji/taskinfo?taskID=10249484

    kexec-tools-2.0.9-1.fc23.x86_64.rpm does not work
    http://koji.fedoraproject.org/koji/taskinfo?taskID=10249201

    kexec-tools-2.0.8-12.fc23.x86_64.rpm does not work
    http://koji.fedoraproject.org/koji/taskinfo?taskID=10249377

• so may be its not kexec-tools version issue

    kexec-tools-2.0.7-26.el7.x86_64.rpm work
    https://brewweb.devel.redhat.com/taskinfo?taskID=9439045
  
  

The only difference which I noticed between working brew and not working koji is that koji introduces "-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1" into gcc command line.

However, I tried -fno-enforce-eh-specs (http://koji.fedoraproject.org/koji/taskinfo?taskID=10250889), but it did not work :(

Only thing remaining is to try 2.0.9/8 in brew..will try that too.
