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.

An user is working on cross compilation of glibc.

  This pseudo patch is required in resolv/Makefile, for the user setup
with recent rhel7 glibc:

+ifeq (yes,$(have-ssp-strong))
 CFLAGS-libresolv += -fstack-protector-strong
 CFLAGS-libnss_dns += -fstack-protector-strong
+endif

then, the user should just do something like this:

echo libc_cv_ssp=no >> config.cache
echo libc_cv_ssp_strong=no >> config.cache

as apparently the user is using a cross compiler built with --disable-libssp.

Please inform the customer that this is outside the scope of support. If they are rebuilding glibc based on RHEL and they don't use a compiler with SSP enabled then they will need to patch their sources.
