== Summary ==
<!-- A sentence or two summarizing what this change is and what it will do. This information is used for the overall changeset summary page for each release. 
Note that motivation for the change should be in the Benefit to Fedora section below, and this part should answer the question "What?" rather than "Why?". -->
Add new permissions, classes, and capabilities to the selinux policy so that system recognizes them and boots without an error message.

== Owner ==
<!-- 
For change proposals to qualify as self-contained, owners of all affected packages need to be included here. Alternatively, a SIG can be listed as an owner if it owns all affected packages. 
This should link to your home wiki page so we know who you are.

== Detailed Description ==

<!-- Expand on the summary, if appropriate.  A couple sentences suffices to explain the goal, but the more details you can provide the better. -->
Several new permissions, classes, and capabilities have been added to Linux kernel recently. The current SELinux policy does not reflect all the changes which means it does not make use of all the potential the kernel provides.

The new features include:
* New classes: lockdown perf_event
* New permissions: watch watch_mount watch_reads watch_sb watch_with_perm
* New capabilities: bpf checkpoint_restore perfmon

== Feedback ==

<!-- Summarize the feedback from the community and address why you chose not to accept proposed alternatives. This section is optional for all change proposals but is strongly suggested. Incorporating feedback here as it is raised gives FESCo a clearer view of your proposal and leaves a good record for the future. If you get no feedback, that is useful to note in this section as well. For innovative or possibly controversial ideas, consider collecting feedback before you file the change proposal. -->

== Benefit to Fedora ==

<!-- What is the benefit to the distribution?  Will the software we generate be improved? How will the process of creating Fedora releases be improved?
  
      Be sure to include the following areas if relevant:
      If this is a major capability update, what has changed?
           For example: This change introduces Python 5 that runs without the Global Interpreter Lock and is fully multithreaded.
      If this is a new functionality, what capabilities does it bring?
           For example: This change allows package upgrades to be performed automatically and rolled-back at will.
      Does this improve some specific package or set of packages?
           For example: This change modifies a package to use a different language stack that reduces install size by removing dependencies.
      Does this improve specific Spins or Editions?
           For example: This change modifies the default install of Fedora Workstation to be more in line with the base install of Fedora Server.
      Does this make the distribution more efficient?
           For example: This change replaces thousands of individual %post scriptlets in packages with one script that runs at the end.
      Is this an improvement to maintainer processes?
           For example: Gating Fedora packages on automatic QA tests will make rawhide more stable and allow changes to be implemented more smoothly.
      Is this an improvement targeted as specific contributors?
           For example: Ensuring that a minimal set of tools required for contribution to Fedora are installed by default eases the onboarding of new contributors. 

     When a Change has multiple benefits, it's better to list them all.

     Consider these Change pages from previous editions as inspiration:
     https://fedoraproject.org/wiki/Changes/Annobin (low-level and technical, invisible to users)
     https://fedoraproject.org/wiki/Changes/ParallelInstallableDebuginfo (low-level, but visible to advanced users)
     https://fedoraproject.org/wiki/Changes/VirtualBox_Guest_Integration (primarily a UX change)
     https://fedoraproject.org/wiki/Changes/NoMoreAlpha (an improvement to distro processes)
     https://fedoraproject.org/wiki/Changes/perl5.26 (major upgrade to a popular software stack, visible to users of that stack)
-->
Adding support for the new features to selinux-policy brings better granularity for granting permissions and have subsequent security benefits.

Additionally, systems can be run with the mls selinux policy: this is currently not possible as using mls policy may prevent a system from starting when there are permissions unknown to the policy which is true in the new kernels.

== Scope ==
* Proposal owners:
<!-- What work do the feature owners have to accomplish to complete the feature in time for release?  Is it a large change affecting many parts of the distribution or is it a very isolated change? What are those changes?-->
** Add all relevant patches to upstream repository
** Ensure the system boots with the targeted policy
** Ensure the system boots with the mls policy
** Ensure the permissions are recognized by the system
** List of the new features and bugzilla links:
*** [https://bugzilla.redhat.com/show_bug.cgi?id=1901957 perf_event class ]
*** [https://bugzilla.redhat.com/show_bug.cgi?id=1915034 watch permissions ]

* Other developers: N/A (not a System Wide Change) <!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
<!-- What work do other developers have to accomplish to complete the feature in time for release?  Is it a large change affecting many parts of the distribution or is it a very isolated change? What are those changes?-->

* Release engineering: [https://pagure.io/releng/issues #Releng issue number] (a check of an impact with Release Engineering is needed) <!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
<!-- Does this feature require coordination with release engineering (e.g. changes to installer image generation or update package delivery)?  Is a mass rebuild required?  include a link to the releng issue. 
The issue is required to be filed prior to feature submission, to ensure that someone is on board to do any process development work and testing and that all changes make it into the pipeline; a bullet point in a change is not sufficient communication -->

* Policies and guidelines: N/A (not a System Wide Change) <!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
<!-- Do the packaging guidelines or other documents need to be updated for this feature?  If so, does it need to happen before or after the implementation is done?  If a FPC ticket exists, add a link here. -->

* Trademark approval: N/A (not needed for this Change)
<!-- If your Change may require trademark approval (for example, if it is a new Spin), file a ticket ( https://pagure.io/Fedora-Council/tickets/issues ) requesting trademark approval from the Fedora Council. This approval will be done via the Council's consensus-based process. -->

* Alignment with Objectives: 
<!-- Does your proposal align with the current Fedora Objectives: https://docs.fedoraproject.org/en-US/project/objectives/ ? It's okay if it doesn't, but it's something to consider -->

== Upgrade/compatibility impact ==
<!-- What happens to systems that have had a previous versions of Fedora installed and are updated to the version containing this change? Will anything require manual configuration or data migration? Will any existing functionality be no longer supported? -->
Users should not be directly affected by this change.

<!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
N/A (not a System Wide Change) 

== How To Test ==
<!-- This does not need to be a full-fledged document. Describe the dimensions of tests that this change implementation is expected to pass when it is done.  If it needs to be tested with different hardware or software configurations, indicate them.  The more specific you can be, the better the community testing can be. 

Remember that you are writing this how to for interested testers to use to check out your change implementation - documenting what you do for testing is OK, but it's much better to document what *I* can do to test your change.

A good "how to test" should answer these four questions:

0. What special hardware / data / etc. is needed (if any)?
1. How do I prepare my system to test this change? What packages
need to be installed, config files edited, etc.?
2. What specific actions do I perform to check that the change is
working like it's supposed to?
3. What are the expected results of those actions?
-->
* Boot a system and check for error messages and audit records.
* Optionally, install and boot the selinux-policy-mls package.

N/A (not a System Wide Change) 

== User Experience ==
<!-- If this change proposal is noticeable by users, how will their experiences change as a result?

 This section partially overlaps with the Benefit to Fedora section above. This section should be primarily about the User Experience, written in a way that does not assume deep technical knowledge. More detailed technical description should be left for the Benefit to Fedora section.

 Describe what Users will see or notice, for example:
  - Packages are compressed more efficiently, making downloads and upgrades faster by 10%.
  - Kerberos tickets can be renewed automatically. Users will now have to authenticate less and become more productive. Credential management improvements mean a user can start their work day with a single sign on and not have to pause for reauthentication during their entire day.
 - Libreoffice is one of the most commonly installed applications on Fedora and it is now available by default to help users "hit the ground running".
 - Green has been scientifically proven to be the most relaxing color. The move to a default background color of green with green text will result in Fedora users being the most relaxed users of any operating system.
-->
There's no visible change for end users.

Admins and custom policy authors may need to get familiar with the new features for services which make use of them.

== Dependencies ==
<!-- What other packages (RPMs) depend on this package?  Are there changes outside the developers' control on which completion of this change depends?  In other words, completion of another change owned by someone else and might cause you to not be able to finish on time or that you would need to coordinate?  Other upstream projects like the kernel (if this is not a kernel change)? -->

<!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
N/A (not a System Wide Change) 

== Contingency Plan ==

<!-- If you cannot complete your feature by the final development freeze, what is the backup plan?  This might be as simple as "Revert the shipped configuration".  Or it might not (e.g. rebuilding a number of dependent packages).  If you feature is not completed in time we want to assure others that other parts of Fedora will not be in jeopardy.  -->
* Contingency mechanism: (What to do?  Who will do it?) N/A (not a System Wide Change)  <!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
<!-- When is the last time the contingency mechanism can be put in place?  This will typically be the beta freeze. -->
* Contingency deadline: N/A (not a System Wide Change)  <!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
<!-- Does finishing this feature block the release, or can we ship with the feature in incomplete state? -->
* Blocks release? N/A (not a System Wide Change), Yes/No <!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
* Blocks product? product <!-- Applicable for Changes that blocks specific product release/Fedora.next -->

== Documentation ==
<!-- Is there upstream documentation on this change, or notes you have written yourself?  Link to that material here so other interested developers can get involved. -->

<!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
N/A (not a System Wide Change) 

== Release Notes ==
<!-- The Fedora Release Notes inform end-users about what is new in the release.  Examples of past release notes are here: http://docs.fedoraproject.org/release-notes/ -->
<!-- The release notes also help users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns.  If there are any such changes involved in this change, indicate them here.  A link to upstream documentation will often satisfy this need.  This information forms the basis of the release notes edited by the documentation team and shipped with the release. 

Release Notes are not required for initial draft of the Change Proposal but has to be completed by the Change Freeze.
