F25 Self Contained Change: NSS enforces the system-wide crypto policy

[Jan Kurik]

= Proposed Self Contained Change: NSS enforces the system-wide crypto policy =
https://fedoraproject.org/wiki/Changes/NSSCryptoPolicies

Change owner(s):
* Nikos Mavrogiannopoulos <nmav AT redhat DOT com>

As it is now, the System-wide crypto policy in F24 is only enforced by
the OpenSSL and GnuTLS TLS libraries. To harmonize crypto in Fedora,
NSS is enhanced to respect the settings of the system-wide crypto
policy as well.

== Detailed Description ==
As it is now, the System-wide crypto policy in F24 is only enforced by
the OpenSSL and GnuTLS TLS libraries. To harmonize crypto in Fedora,
NSS is enhanced to respect the settings of the system-wide crypto
policy as well.
After that change the administrator should be assured that any
application that uses NSS will follow a policy that adheres to the
configured profile.


== Scope ==
* Proposal owners:
The change requires modifying the NSS library to read a policy
generated by the crypto-policy package.

* Other developers:
There are no required actions by other developers. The change requires
only targeted changes to NSS.

* Release engineering:
No actions required.

* Policies and guidelines:
- The packaging guidelines for crypto policies need to be modified to
include NSS in the list of libraries supporting the policies.
- The text "(note that adherence to the system-wide policies is work
in progress for NSS libraries)" must be removed
- The text "Currently the policies are restricted to applications
using GnuTLS and OpenSSL" must be changed to include NSS.

* Trademark approval:
N/A (not needed for this Change)

IYTM "enforces *some* of the system-wide crypto policy".

We also have a policy (in p11-kit config) for which PKCS#11 tokens
should be loaded into which applications. I suppose you could play
semantic games and say that's not really part of the "system-wide
crypto policy" you were talking about. But please don't :)

As things stand, NSS is a holdout in that respect too. If we were to
rebuilt curl against GnuTLS¹, the right tokens would automatically be
available. As it's currently built against NSS, they aren't.

This is https://bugzilla.redhat.com/show_bug.cgi?id=1173577 — and it
might even be relatively easily solved just by loading p11-kit-proxy.so 
by default whenever the NSS database is initialised (without the NoDB
flag).

Please could we make an effort to get that fixed at the same time? The
patches you have as part of this Change are touching the *same* code in
nss_InitModules() which needs to be fixed up for loading the right
modules, too.

Keep in mind that the system policy is still overridden by glib-
networking for all GNOME applications.

This is a serious bug, but I don't really want to keep that in mind :) 

I've already commented in

What is the impact on openjdk crypto providers?

The impact in what sense? Note that openjdk will also conform to the
system wide policy.

It's my understanding that there's been some recent work to move openjdk to
certain NSS security providers (for EC, for example). But, I think you
already answered my (poorly worded) question. Thanks.
