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.

Description Miroslav Franc 2012-03-30 07:53:24 UTC

Description of problem:

When poking at bug 807740 I hit another segfault in dynamic linker. It manifest itself, when running ld.so --verify on some DSO's in current working directory. Upstream 6a5ee1029b3966c5ae9adaaa881e255b2880f511 seems to be fixing the issue for me.


Version-Release number of selected component (if applicable):
glibc-2.12-1.75.el6


How reproducible:
Always.


Steps to Reproduce:
cd /lib; for i in *; do /lib/ld-linux.so.2 --verify "$i";done


Actual results:
A lot of segfaults.


Expected results:
No segfault.

Comment 1 Jeff Law 2012-03-30 19:23:16 UTC

I wouldn't mind adding the referenced patch to 6.3; it's small and reasonably safe.  It's arguably related to 741105/767146 and a testcase which tests ld --verify doesn't fault on a wide set of libraries and debuginfo files would cover testing for both BZs.
