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.
+++ This bug was initially created as a clone of Bug #1022478 +++
Description of problem:
Because different TLS servers and clients may support different curves for ECDHE cipher suites, we need to be able to test situations in which the client and server support different curves. Or if the default server curve is unsupported by the client.
Version-Release number of selected component (if applicable):
openssl-1.0.1e-15.el6.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Start openssl s_server
2. Grab all packets comming to s_server
3. Try to connect using s_client -named_curve secp256r1
4. Decode packet capture, check curves advertised in ClientHello
Actual results:
All curves supported are listed
Expected results:
Only secp256r1 listed
Additional info:
Needed for automatic verification of bug 1022468

This would have to be consulted with upstream - we in general do not want to add new functionality to openssl that is not accepted upstream.

AFAIK that's the case for all functionality we provide in RHEL packages.
We still need a tracking bug to backport it.
This functionality is implemented in upstream OpenSSL 1.0.2 (current beta), the option is named "-curves" and accepts curve names separated by colons. It is documented in master branch in SSL_CONF_cmd man page.
Unfortunately, it was implemented using mechanisms not present in 1.0.1, so it would require non-insignificant effort to backport.
