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the product is no longer active in Red Hat Bugzilla.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.
One of the backports for Bug 2058444 introduced libxtables ABI breakage, fix
this by backporting the following commit:
commit a7c2b7289cd31455b854fee7d5c735c6270518a3
Author: Phil Sutter <phil>
Date: Fri May 6 00:11:47 2022 +0200
libxtables: Revert change to struct xtables_pprot
While protocol values may exceed eight bits, the data structure is
indeed used only to store the static list of name/value pairs for faster
lookups. None of those has such a value and if one is added in future,
the compiler will complain about it.
So restore the old field type to retain binary compatibility.
Fixes: 556f704458cdb ("Use proto_to_name() from xshared in more places")
Signed-off-by: Phil Sutter <phil>
RHEL9 is unaffected, RHEL8.6 has the fix already via Bug 2137953, RHEL8.7 needs
to be fixed as well.
Marking as TestOnly since the fix is already contained in backports for bug 2211063.
Given the fact that there is no functional change (unless crafted by custom code relying upon the data structure layout), sanity only testing probably suffices.
