RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Could you please post the output of check-localplt.out?

If it's just a testsuite issue where a PLT entry is elided then we can at our discretion (rhe-7.5) backport the testsuite fixes to remove the failure.
Comment 3 Sergey Kolosov 2017-04-07 17:12:23 UTC 
Sure, check-localplt.out is attached: "elf-check-localplt test output"

This should fix it:

    Fix localplt test breakage with new readelf
Comment 7 Florian Weimer 2017-09-25 13:48:42 UTC 
I also see some new ifunc failures on x86-64, which are related to the binutils rebase.

/usr/bin/ld: /root/build/elf/ifuncmod1.os: relocation R_X86_64_PC32 against protected symbol `global' can not be used when making a shared object
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status
make[2]: *** [/root/build/elf/ifuncmod1.so] Error 1

The above should be fixed by this upstream commit:

commit e0ed2fb40a0e29c43cf60addc74741dab15f2e05
Author: H.J. Lu <hjl.tools>
Date:   Fri Mar 6 04:55:56 2015 -0800

    Replace __attribute__((visibility("protected")))
    
    With copy relocation, address of protected data defined in the shared
    library may be external.  Compiler shouldn't asssume protected data will
    be local.  But due to
    
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248
    
    __attribute__((visibility("protected"))) doesn't work correctly, we need
    to use asm (".protected xxx") instead.
