NSS load p11-kit modules by default
Summary
When NSS database is created, PKCS#11 modules configured in the system's p11-kit will be automatically registered and visible to NSS applications.

Current status
- Targeted release: Fedora 29
- Last updated: 2018-06-04
- Tracker bug: <will be assigned by the Wrangler>
Detailed Description
Fedora provides a mechanism to configure PKCS#11 modules system wide, allowing the crypto libraries (GnuTLS and OpenSSL) to use PKCS#11 modules in a consistent manner. Until now NSS applications haven't benefit from it as NSS uses a different configuration mechanism which requires users to register PKCS#11 modules in NSS databases. This change makes the manual procedure unnecessary, by registering the p11-kit-proxy module (the aggregator of the system PKCS#11 modules) in NSS databases with the default configuration.

Benefit to Fedora
This change allows NSS applications to use PKCS#11 modules in the same way as other crypto libraries, bringing consistency in PKCS#11 driver registration across the OS. That improves user experience of smartcards and HSMs on Fedora.
Scope
- Proposal owners:
- Enable p11-kit-proxy in the newly created NSS database, through the crypto-policies package.
- Modify the opensc package not to register itself to the NSS database upon installation.
- Make sure that this change doesn't cause any regression with the existing applications.
- Other developers: None
- Release engineering: #Releng issue number (a check of an impact with Release Engineering is needed)
- List of deliverables: N/A
- Policies and guidelines: PackageMaintainers/PKCS11 needs changes basically to eliminate NSS specific stuff
- Trademark approval: N/A (not needed for this Change)
Upgrade/compatibility impact
Uncommon/undocumented scenarios may be affected, in particular if the user previously used a configuration which conflicts with this change.
How To Test
- install a PKCS#11 module, say softhsm2
- create an NSS database
- list modules registered to the NSS database, and check that there is softhsm2
User Experience
The users of NSS applications (e.g. firefox and sssd) would be able to use supported smartcards and HSMs without further configuration.
Dependencies
firefox, and possibly sssd's smartcard support
Contingency Plan
- Contingency mechanism: Revert the change in crypto-policies
- Contingency deadline: Beta freeze
- Blocks release? No
- Blocks product? No
Documentation
No new documentation, but the existing documentation needs to be changed to not mention the special case of NSS.
Release Notes
It should be sufficient to have a simple sentence mentioning this change and how to opt-opt from it.
