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.

Fixed In Version: glibc-2.12-1.207.el6
Doc Type: Bug Fix
Doc Text:
Resolution for gcc compatibility issue with "sockaddr_in" The default RHEL 6 compiler has rules about how to copy "struct sockaddr_in" that are substantially different to those used by later versions of gcc (E.g. the tools provided with Red Hat Developer Toolset). This caused corrupted sockaddr_in overlays when using newer compilers. This update changes the way the "unused" portions of the sockaddr_in structure are defined. Now, newer versions of gcc will copy them correctly. Note that -fno-strict-aliasing is still required for compiling such sources.

Description Florian Weimer 2016-05-23 08:50:27 UTC 
+++ This bug was initially created as a clone of Bug #1337291 +++

The current struct sockaddr_storage definition causes problems with GCC 6 which are not fixed by -fno-strict-aliasing.  We need to backport a definition which compensates for this.
