Description Michael S. 2016-11-19 08:54:45 UTC
Description of problem:

last week, I switched cryptopolicy to FUTURE in /etc/cryptopolicy/config and promptly forgot about it. 

And today, while trying to update my Fedora system, i was greeted by dnf errors regarding mirror likst for rpmfusion, then fedora, with in the end the following issue:

# curl 'https://mirrors.fedoraproject.org/metalink?repo=fedora-25&arch=x86_64'                                                          
curl: (35) SSL version range is not valid.  

So using FUTURE mean that we can't update the system, and that seems a bit annoying. 

There is several issue here to fix:
- the error message is quite puzzling on dnf side, and also on curl side.
- the "FUTURE" is either not usable systemwide

So should the setting be more adapted, or should something should be changed on Fedora side to use proper cipher ? 

Version-Release number of selected component (if applicable):
crypto-policies-20160921-2.git75b9b04.fc25.noarch

How reproducible:
each time

Steps to Reproduce:
1. set FUTURE in /etc/cryptopolicy/config
2. udate-cryptopolicy
3. run dnf update

Actual results:
puzzling error message

Expected results:
stuff should be working

Comment 1 Michael S. 2016-11-19 10:20:12 UTC
so after doing some fiddling, the issue is:
tls-version-min=tls1.2

anything different from tls-version-min=tls1.0 fail. I am not sure if the issue is on curl side, or on the cryptopolicy side

Comment 2 Nikos Mavrogiannopoulos 2016-11-21 07:43:21 UTC
It seems the issue is in curl. If I provide explicitly TLS1.2 it works:

$ curl --tlsv1.2 https://www.google.com
<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
...


Otherwise:

$ curl https://www.google.com
curl: (35) SSL version range is not valid.


It seems its code cannot cope with NSS having TLS 1.0 or TLS 1.1 disabled.

Comment 3 Kamil Dudka 2016-11-21 08:45:13 UTC
Thank you for reporting the bug!  The following upstream commit will fix it:

Comment 4 Kamil Dudka 2016-11-21 09:09:13 UTC
I have also included the --tlsv1.3 option to ease future testing of TLS 1.3:

Comment 5 Nikos Mavrogiannopoulos 2016-11-21 09:13:33 UTC
Kamil could you include that fix in F25 as well? F25 is the first release with NSS supporting crypto policies.

Comment 6 Kamil Dudka 2016-11-21 09:21:49 UTC
(In reply to Nikos Mavrogiannopoulos from comment #5)
> Kamil could you include that fix in F25 as well?

Sure.  It is already included in dist-git (master and f25 share the same commit object).  I am only waiting with the f25 build till the rawhide build finishes.  Otherwise both the builds would fail due to port collisions in the upstream test suite in case a pair of builds was accidentally assigned to the same build host in Koji.
