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 Martin Poole 2014-10-24 12:14:00 UTC
Created attachment 950373 [details]
Patch to add missing cipher names.

Description of problem:

curl has a list of ciphers that are not enabled by default that it adds to the library default selection in the absence of any explicit ciphers.

  /* following ciphers are new in NSS 3.4 and not enabled by default, therefore
     they are enabled explicitly */
  static const int enable_ciphers_by_default[] = {
    TLS_DHE_DSS_WITH_AES_128_CBC_SHA,
    TLS_DHE_DSS_WITH_AES_256_CBC_SHA,
    TLS_DHE_RSA_WITH_AES_128_CBC_SHA,
    TLS_DHE_RSA_WITH_AES_256_CBC_SHA,
    TLS_RSA_WITH_AES_128_CBC_SHA,
    TLS_RSA_WITH_AES_256_CBC_SHA,
    SSL_NULL_WITH_NULL_NULL
  };

Unfortunately these ciphers are not made available in the list of choosable ciphers and so cannot be explicitly selected for use.


Version-Release number of selected component (if applicable):

curl-7.29.0-19.el7

Comment 6 Kamil Dudka 2014-10-24 13:06:49 UTC
The upstream patch referenced in bug 1066065 already solves the problem you reported, in a portable way.  There is no point in tracking this bug report separately.
