Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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 of problem:

Running annocheck on  /lib64/libc.so.6 ppc64le segfaults when debuginfos are installed.

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

annobin-annocheck-9.90-1.el9.ppc64le
glibc-2.34-2.el9.ppc64le

How reproducible:

Deterministic.

Steps to Reproduce:
1. dnf install -y /usr/bin/annocheck glibc
2. dnf debuginfo-install -y glibc
3. annocheck --verbose --verbose --ignore-gaps --skip-all --test-pic --test-pie --test-stack-prot /lib64/libc.so.6

Actual results:

The output ends with

Hardened: Scanning 495 lines in the DWARF line table.
Hardened: Scanning 223 lines in the DWARF line table.
Hardened: Scanning 223 lines in the DWARF line table.
Hardened: Scanning 208 lines in the DWARF line table.
Hardened: Scanning 680 lines in the DWARF line table.
Hardened: Scanning 684 lines in the DWARF line table.
Hardened: Scanning 140735355811408 lines in the DWARF line table.
Segmentation fault (core dumped)

Expected results:

No segfault.

Additional info:

When annocheck is run in a pipe, that last line

Hardened: Scanning 140735355811408 lines in the DWARF line table.

is not shown, likely due to buffering.

For the record, I see the same segfault even when I downgrade to (say) annobin-annocheck-9.83-1.el9.ppc64le, so it's not a recent regression.

I think the issue is that annobin doesn't check whether the elfutils/libdw dwarf_getsrclines () call succeeds, if it fails lines will not be set, but be some random number.

Thanks Mark - yes the problem is that annoeck is not testing a return code from an elfutils library call.
Fixed in rawhide - waiting for RHEL 9.0 development to open.

Fixed in annobin-10.06-1.el9
