Description Harald Reindl 2013-10-15 11:20:08 UTC
that is the state of OpenSSL in Fedora after this morining
https://bugzilla.redhat.com/show_bug.cgi?id=319901#c108

Comment 1 Harald Reindl 2013-10-15 11:31:35 UTC
since OpenSSL in Fedora from now on supports ECDHE
depending software needs to be rebuilt to make use
of it as well as libraries like NSS/GNUTLS should
do the same and depending packages like Firefox
needs a rebuild against refreshed NSS to support 
it also on the client side

i made some triage today

Comment 3 Harald Reindl 2013-10-21 21:14:56 UTC
the "only ECC NIST Suite B curves support" seems to cripple down openssl again
with "openssl-1.0.1e-4.fc18.1" all fine over days and starting with "openssl-1.0.1e-28.fc18" a few messages like below in maillog and lead to fall back to a unecnrypted connection (yes postfix was rebuilt against the new SSL build)

Comment 5 Harald Reindl 2013-10-21 21:36:57 UTC
what a shame - sorry - the above two comments belongs to 
https://bugzilla.redhat.com/show_bug.cgi?id=1019390#c2

Comment 6 Harald Reindl 2013-10-31 19:07:19 UTC
this bugreport is for F18, until now only for F20 are updates of httpd available in the fedora-repos while NSS for TB/Firefox now supports ECDHE

Comment 7 Scott Shambarger 2013-11-15 15:30:14 UTC
If possible, could we get a rebuild for F19 as well?

Comment 8 Joe Orton 2013-11-18 12:15:12 UTC
Upstream is gearing up for 2.4.7 RSN - ECC support will get picked up automagically when we do a new f19 build.

Comment 9 Fedora End Of Life 2013-12-21 15:48:14 UTC
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 10 Alicja Kario 2014-01-21 17:11:31 UTC
Problem is still present in Fedora 19. Upping version number to prevent the bot from closing bug.

mod_ssl-2.4.6-2.fc19.x86_64
openssl-1.0.1e-37.fc19.x86_64

Comment 11 Harald Reindl 2014-01-21 17:19:47 UTC
this is because nobody cared to build apache 2.4.7 for F18/F19 or 
at least rebuild 2.4.6 - that's why i maintain my own server 
packages and at 2013-10-15 our F18 infrastructure started to
support ECDHE as well as now after F19 upgrade

Comment 12 Harald Reindl 2014-01-21 17:25:13 UTC
http://koji.fedoraproject.org/koji/packageinfo?packageID=280

2.4.7 has also a lot of other bugfixes
http://httpd.apache.org/dev/dist/CHANGES_2.4.7

even the apache package of RHEL7-Beta1 supports ECDHE
httpd-2.4.6-7.el7.x86_64

Comment 13 Fedora Admin XMLRPC Client 2014-06-30 09:53:45 UTC
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Comment 14 Jan Kaluža 2014-08-20 11:39:49 UTC
We have 2.4.10 now in all supported Fedora versions, so it should be fixed now.
