Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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 Florian Weimer 2015-05-05 07:53:57 UTC

The binaries contain what looks like a TLS 1.2 implementation, but it is disabled by default, and the NEWS file indicates it was written when TLS 1.2 was not yet published.

What is the support status of the TLS 1.2 implementation?  Does it actually implement the TLS 1.2, or something subtly different because it is older than the RFC?

If the code is supportable, shouldn't it be enabled by default?

Comment 1 Nikos Mavrogiannopoulos 2015-05-05 08:02:52 UTC

Hi, it implements the current (at the time) draft for TLS 1.2, and even that is incomplete. That cannot be supported in any way as it is.

In this case, TLS 1.2 support be completely disabled, not just disabled by default.  Otherwise, customers will increasingly try to enable it and unexpectedly end up with a faulty TLS 1.2 implementation.
