FreeBSD Quarterly Status Report - 2nd Quarter 2017

   FreeBSD continues to defy the rumors of its demise.

   Much of the development work done this quarter was not particularly
   visible, especially the effort needed to ensure the upcoming 11.1
   release has as few regressions as possible. Planning is also well under
   way for the 10.4 maintenance release which will quickly follow it.

   Further work focused on moving the arm architectures' support closer to
   tier-1 status and improving documentation. In addition, large changes
   were made to the src and ports trees.

   These projects and others are further detailed below.

   The FreeBSD Release Engineering Team is responsible for setting and
   publishing release schedules for official project releases of FreeBSD,
   announcing code freezes, and maintaining the respective branches, among
   other things.

   The FreeBSD 11.1-RELEASE cycle started on May 19, and continued as
   scheduled. FreeBSD consumers are urged to test whenever possible to
   help ensure the reliability and stability of the upcoming second
   release from the stable/11 branch.

   This project was sponsored by The FreeBSD Foundation.

   This quarter, 2017Q2, broke the 30,000 ports landmark for the first
   time. The PR count is currently just under 2,500, with almost 600 of
   them unassigned. This quarter saw almost 7,400 commits from 171
   committers. More PRs got closed this quarter than last quarter, but
   also more PRs got sent in, both of which are good to see.

   Over the past three months, we welcomed four new committers: Bradley T.
   Hughes (bhughes@), Danilo G. Baio (dbaio@), Jochen Neumeister
   (joneum@), and Richard Gallamore (ultima@). kan@ re-joined us as a
   ports committer. One commit bit, that of bf@, was taken in for
   safekeeping after a long period of inactivity.

   On the management side, the Ports Management Team welcomed back bapt@,
   who is working on several new features for the Ports Tree. The Ports
   Management Team also had its annual real-life meeting during BSDCan.

   On the infrastructure side, three new USES values were introduced:
     * cargo, to ease the porting of Rust packages or binaries using the
       cargo command (also covered separately in this report)
     * groff, to handle a dependency on the groff document formatting
       system, that has been removed from the base system for FreeBSD 12
     * meson, to provide support for projects based on Meson

   The default version of PostgreSQL switched from 9.3 to 9.5, and that of
   Python3 from 3.5 to 3.6. The default generator for ports using cmake
   has been switched to ninja.

   Some major version updates are: pkg 1.10.1, Firefox 54.0.1, and
   Chromium 59.0.3071.115.

   Behind the scenes, antoine@ ran 36 exp-runs to test version updates,
   make the CRAN ports platform-independent, test installing bsdgrep(1) as
   /usr/bin/grep, test LLVM updates, test the ino64 project, and perform
   Makefile cleanups.

The FreeBSD Core Team

   Contact: FreeBSD Core Team <core@FreeBSD.org>

   Core's activities during the second quarter culminated in the
   introduction of two new initiatives during BSDCan:
     * Extending FreeBSD Project Membership
     * The FreeBSD Community Process

   FreeBSD Project Members

   FreeBSD Project Membership being extended to more than just committers
   is a step that enables the Project to recognise and reward people who
   support us in ways other than by writing code. People that organise
   conferences or user groups; who are prominent supporters on social
   media; who triage bug reports and who test changes; and many others who
   contribute in various ways, are deserving of recognition for the
   support that they give to the Project. Core hopes that this will both
   encourage more people to volunteer their time and effort on behalf of
   the Project, and encourage those who already do to stick with the
   Project, if not become more deeply involved.

   The naming for the new group of non-committer Project members took a
   few tries to get right: having tried, and rejected, "Contributor" and
   then "Associate", Core took the view that since what they were
   offerring was formal Project Membership, then that was the right thing
   to call it. Committers thus become those Project Members with access to
   commit to the Project's code repositories. Project Members receive an
   @FreeBSD.org e-mail address, access to various Project hardware, access
   to internal mailing lists and other communications channels, and
   invitations to attend Developer Summits in their own right. Committers
   in addition have commit rights in the Subversion repositories and
   GitHub, and active Committers can vote in Core team elections.

   The FreeBSD Community Process

   This is an idea that has a long pedigree within other projects, and
   FreeBSD is very consciously modelling its implementation on what has
   worked elsewhere. When a significantly disruptive or wide-scale change
   is proposed, we should have a formal mechanism for documenting the
   change and what it implies. Interested parties can then respond and the
   change can be evolved into the best fit for all users, or else it can
   be found to be impracticable and withdrawn. The documentation of the
   change will remain as a point of reference should the same or a similar
   proposal come up in the future. Creating a more formal process should
   help avoid endless sterile arguments about what needs to be done,
   without anyone feeling they have sufficient investment in the idea nor
   backing from the majority of the project to justify putting in the work
   to achieve the desired result.

   The very first FCP -- FCP 0 -- describes the process itself. At the
   time of this writing, Core is voting on accepting the initial document,
   which can be viewed in the Project's Github repository. Two new mailing
   lists have been created: fcp@FreeBSD.org is the channel for receiving
   notifications of new FCP proposals and discussing their content, whilst
   fcp-editors@FreeBSD.org exists to provide help with the process of
   drafting the FCP documents.

   Other Core activities

   Core is delighted to announce that Gordon Tetlow has joined the
   Security Officer team, and will be working on managing the Security
   Team caseload, freeing up other members to concentrate on the more
   technical aspects of vulnerability remediation. In addition, Ed Maste
   has joined the Security Team and is available to assist the Security
   Officers where necessary.

   Although Florian Smeets had to step down, the postmaster team has
   recruited three new members and is now back up to strength.

   Considering the desirability of a number of fixes that have been merged
   into 10-STABLE since the 10.3 release, core has approved a 10.4 release
   to occur shortly after the 11.1 release. This will be a normal
   support-lifetime release, unlike the extended lifetime of the 10.3
   release, so the overall support lifetime for the 10.x branch will not
   be significantly extended.

   During this quarter, Core has approved issuing three new commit bits.
   Please welcome:
     * Vladimir Kondratyev (wulf@)
     * Ryan Libby (rlibby@)
     * Kyle Evans (kevans@)

   Also, during this quarter, we had one person give up their commit bit:
     * Jordan Hubbard (jkh@)

   It is always unsettling when one of the Project's founding members
   decides to move on, but Jordan's interests have migrated away from
   FreeBSD-related projects and he has decided to hang up his bit once and
   for all.

   Core would like to thank NTTA (formerly Verio) for providing hosting
   for a cvsup mirror for many years, and also for their kind offer to
   provide ongoing hosting for a machine in their Seattle facility. Since
   we have no need for additional North America hosting, we have declined
   their offer.

   As usual, a number of questions have been raised about code licensing
   and other matters related to intellectual property. Ed Maste has
   registered "freebsd" on behalf of the FreeBSD Foundation on the
   Mastodon social media network. The "Unlicense" is suitable for code
   being imported into libc. We still have some code published under the
   old 4-clause style BSD license, where the extra clause refers
   specifically to the University of California. While UC has generally
   approved removing that clause, we need to check with all copyright
   holders before changing any remaining 4-clause licensing.

   Core, along with the Security Team, are monitoring developments
   concerning the "Stack Clash" vulnerability that hit the headlines
   during June. Changes to the stack-guard mitigation system are underway
   as a response to the proof-of-concept published by Qualys.

   Last quarter the Foundation was busy supporting the FreeBSD Project in
   so many ways! We brought on two interns from the University of Waterloo
   who were extremely productive, from working on a continuous integration
   project to adding MSDOS FAT filesystem support to makefs. We continued
   helping to accelerate OS changes with our internal staff of software
   developers, as well as funding outside software development projects,
   and continued promoting FreeBSD by participating in technology
   conferences around the world. To encourage more commercial users to
   donate to the Foundation, we launched a new partnership program. The
   FreeBSD 11.1 release effort has been led by a full-time Foundation
   employee, to continue keeping releases timely and reliable. Finally, we
   led the effort to celebrate the newly declared FreeBSD Day, to help
   raise awareness of FreeBSD around the world!

   Below, you can read some of the highlights from our Q2 newsletter, and
   find writeups throughout this status report from Foundation staff
   members including Ed Maste, Kostik Belousov, and Glen Barber. Don't
   forget, we are 100% funded by donations. Please take a moment to donate
   now, so we can continue supporting the FreeBSD Project and community
   worldwide!

   Q2 Development Projects Summary

   Our hard work continues into the 2nd quarter of 2017. Please take a
   look at the highlights from our more recent Development Projects
   summaries.

   April: FreeBSD USB Mass Storage Target Project Update

   The Foundation awarded a project grant to Edward Tomasz Napiera=C5=82a to
   develop a USB mass storage target driver, using the FreeBSD CAM Target
   Layer (CTL) as a backend. This project allows FreeBSD on an embedded
   platform, such as a BeagleBone Black or Raspberry Pi Zero, to emulate a
   USB mass storage target, commonly known as a USB flash stick. Read more
   at https://www.FreeBSDfoundation.org/blog/april-2017-development-project=
s-update/.

   May: Foundation Brings on Co-Op Students

   At the beginning of May we embarked on a new path in the FreeBSD
   Foundation, with the hiring of co-operative education (co-op) students
   from the University of Waterloo. The University of Waterloo is a
   pioneer and leader in co-operative education, with 100% of Engineering
   students and a majority of Computer Science students participating in
   co-op programs. Read more at
   https://www.FreeBSDfoundation.org/blog/may-2017-development-projects-upd=
ate/.

   June: FreeBSD Foundation 2017 Project Proposal Solicitation
   (contributed by Ed Maste)

   One of the ways the Foundation supports FreeBSD is by providing
   development grants for work on individual projects. These allow
   developers to propose projects they would like to undertake to improve
   FreeBSD and request funding to perform that work. The Foundation is
   always willing to receive proposals, but will occasionally issue a call
   for proposals to highlight specific areas of focus and to be able to
   collect and evaluate a group of proposals.

   The proposal submission deadline was July 14, 2017, but as mentioned
   above, people are welcome to submit proposals at any time.

   Although proposals may address any FreeBSD subsystem or infrastructure,
   we are particularly interested in receiving proposals related to:
     * Improvements to the security of FreeBSD itself, or of applications
       running on FreeBSD
     * New test cases, improved test infrastructure, and quality assurance
     * Improved software development tools
     * Projects to improve community collaboration and communication
     * Improving the FreeBSD "out of the box" experience for new users on
       various hardware platforms
     * Establishing FreeBSD as a leader in advancing projects of shared
       interest (such as ZFS, LLVM, or libarchive)

   More details can be found at
   https://www.FreeBSDfoundation.org/blog/FreeBSD-foundation-2017-project-p=
roposal-solicitation/.
   The full project proposal submission guidelines can be found at

   Please do not hesitate to contact proposals@FreeBSDfoundation.org with
   any questions.

   Announcing the New Partnership Program (contributed by Deb Goodkin)

   I'm excited to announce our new FreeBSD Foundation Partnership Program!
   Our work is 100% supported by donations from individuals and
   organizations. With a spending budget of $1,500,000, we rely on large
   donations from our commercial users to help us sustain and increase our
   support. Recognizing the value of these donations, and putting together
   a sustainable funding model, we wanted to institute benefits that
   highlighted this support, and recognize these donors in productive
   ways. Partnerships are an avenue to assist commercial users by helping
   them get on board more quickly with FreeBSD, share their needs with the
   community, and facilitate collaboration with FreeBSD developers. We
   believe that building these relationships with commercial users will
   contribute to keeping FreeBSD relevant and help provide a sustainable
   and healthy ecosystem.

   You can check out our updated donor pages to see how we are
   acknowledging our Partners at
   https://www.FreeBSDfoundation.org/donors/. You can also find out more
   about this new program at
   https://www.FreeBSDfoundation.org/FreeBSD-foundation-partnership-program=
/.

   When I was in China last week, I had a chance to talk to a few
   companies about our new partnership program, and it definitely
   generated more interest in supporting our efforts.

   We are continuing to reach out to commercial users for help that will
   enable us to provide more outreach and support for FreeBSD. This
   includes funding more projects to improve FreeBSD, providing FreeBSD
   education and training, and recruiting more contributors to the
   Project. We can only provide the above support with your donations, and
   we need your help to connect us with your companies. Please consider
   notifying your organization about our new Partnership Program and
   helping to connect us with the appropriate contacts at your company.

   Your donations will help us:
     * Accelerate improvements and add new features to FreeBSD
     * Support release engineering efforts full-time
     * Create and provide FreeBSD educational and training material
     * Provide face-to-face opportunities for developers to work together
     * Improve and support FreeBSD infrastructure

   We need your support to continue improving FreeBSD.

   Q2 2017 Conference Recaps

   From sponsoring events to attending conferences, the Foundation
   continued its mission of advocacy in the second quarter of 2017. Over
   the past few weeks, members of the Foundation team represented the
   Project and the Foundation at events around the world. Below are just a
   few of the conference recaps.

   FOSSASIA 2017 (contributed by Philip Paeps)

   The Foundation kindly funded part of my travel from Tokyo to Singapore
   to attend FOSSASIA. I gave the "FreeBSD is not a Linux Distribution"
   presentation that Foundation board member George Neville-Neil wrote for
   Open Source China in December. My presentation was well-attended, and I
   got a lot of good questions from the primarily Linux-oriented audience.

   OSCON 2017 (contributed by Ed Maste)

   I represented the FreeBSD Foundation at OSCON 2017, which took place
   May 8-11, 2017, in Austin, TX:
   https://conferences.oreilly.com/oscon/oscon-tx .

   The Foundation booth was also staffed by FreeBSD committer Brad Davis
   and Doug Mcintire from Netgate. We met up Wednesday morning to set up
   the table. We were part of a "nonprofit pavilion" which consisted of
   eight or so tables, located between Open Camps and Operation Code.

   To help attract booth traffic, I brought a Raspberry Pi 3, with a small
   LCD display attached. As a demo, the Raspberry Pi showed a video of a
   Gource rendering of changes to the FreeBSD source tree over time (see
   example at https://www.youtube.com/watch?v=3DvZ8Sspua0Ks). Read more at
   https://www.FreeBSDfoundation.org/blog/conference-recap-oscon-2017/.

   Rootconf 2017 (contributed by Philip Paeps)

   In mid-May I presented at Rootconf 2017 in Bangalore. Rootconf is
   India's principal conference where systems and operations engineers
   share real-world knowledge about building reliable systems:
   https://rootconf.in/2017/.

   As always, it was interesting to hear the difficulties people face
   trying to run reliable systems on less reliable platforms. While many
   of the presentations were very Linux-specific and not very exciting to
   me, a couple of talks did catch my eye.

   I particularly enjoyed the talk by Aruna Sankaranarayanan
   (https://www.youtube.com/watch?v=3DXQJ7YhVoSWI&feature=3Dyoutu.be)
   explaining how Mapbox takes advantage of Amazon's "spot pricing"
   mechanism by spawning and shutting down machines at different price
   points to optimize for cost without compromising availability. Their
   spotswap https://github.com/mapbox/spotswap/ software has been released
   under a BSD license. It sounds as though it should be possible to port
   this to FreeBSD with minimal effort. Read more at
   https://www.FreeBSDfoundation.org/blog/rootconf-2017-trip-report-philip-=
paeps/.

   BSDCan 2017/FreeBSD Developers Summit (contributed by Deb Goodkin)

   One of our initiatives is to assist in providing face-to-face knowledge
   sharing and development opportunities around the world. One way we do
   this is by sponsoring BSD-related conferences and FreeBSD Developer and
   Vendor Summits. We recently sponsored both BSDCan 2017 and the FreeBSD
   Developer and Vendor Summit in Ottawa, Ontario, Canada, which took
   place June 7-10, 2017. Many of our board and staff members attended the
   summit and conference to run tutorials, give presentations, lead
   sessions, work with developers, give demos, and share knowledge.

   In addition, this year we were pleased to bring our new University of
   Waterloo interns to the conference where they had the opportunity to
   demonstrate some of their projects at the Foundation table. Read more
   at https://www.FreeBSDfoundation.org/blog/conference-recap-bsdcan-2017Fr=
eeBSD-developers-summit/.

   Open Travel Grant Applications

   The Foundation recognizes the importance of bringing members of the
   FreeBSD community face-to-face to both further development of the
   Project and spread the word about FreeBSD. Travel grants are available
   to community members who need assistance with travel expenses for
   attending conferences related to FreeBSD development and advocacy.
   Please note: the travel grant policy has been recently updated. Please
   carefully review it before submitting your application.

   More information about travel grants is available at:
   https://www.FreeBSDfoundation.org/what-we-do/grants/travel-grants/.

   Postmaster handles the mail flow for the FreeBSD project.

   Clusteradm provides us with four jails: mailman, mailarchive, mx1, and
   mx2. In addition, there is some part of the setup running on
   freefall.FreeBSD.org. The system uses postfix, mailman, spamassassin,
   and some other tools from the ports tree to handle the mail flow. We
   use a very small, non-public Subversion repository for parts of the
   configuration.

   During Q2, Larry Rosenman, Kurt Jaeger, Eygene Ryabinkin, Remko Lodder
   and Ryan Steinmetz joined the Postmaster Team, and Florian Smeets left
   the Postmaster Team.

   Thanks to Florian for his long service in that role! David Wolfskill is
   planning to leave the role as soon as the new team members are settled.
   Vsevolod Stakhov plans to provide us with support to integrate rspamd
   into the setup, as well.

   The workload for the Postmaster Team is not high, but the complexity of
   the setup has its own demands.

   Open tasks:

    1. We need to improve our internal documentation of workflows and
       processes.
    2. We should consider adding some monitoring to provide quarterly
       numbers on the mail flow.

64-bit Inode Numbers

   Phabricator Review
    URL: https://reviews.FreeBSD.org/D10439

   Contact: Gleb Kurtsou <gleb@FreeBSD.org>
   Contact: Konstantin Belousov <kib@FreeBSD.org>
   Contact: Kirk McKusick <mckusick@FreeBSD.org>

   The 64-bit inode project was completed and merged into FreeBSD 12 on
   May 23, 2017. It extends the ino_t, dev_t, and nlink_t types to be
   64-bit integers. It modifies the struct dirent layout to add a d_off
   field, increases the size of d_fileno to 64 bits, increases the size of
   d_namlen to 16 bits, and changes the required alignment of the
   structure. It increases the struct statfs f_mntfromname[] and
   f_mntonname[] array lengths from MNAMELEN to 1024.

   ABI breakage is mitigated by providing compatibility using versioned
   symbols, ingenious use of the existing padding in structures, and
   employing various other tricks. Unfortunately, not everything can be
   fixed, especially outside the base system. For instance, third-party
   APIs which pass struct stat as parameters are broken in backward- and
   forward-incompatible ways.

   The ABI for kinfo-consuming sysctl MIBs is changed in a
   backward-compatible way, but there is no general mechanism to handle
   other sysctl MIBS which return structures where the layout has changed.
   In our consideration, this breakage is either in management interfaces,
   where we usually allow ABI slippage, or is not important.

   The layout of struct xvnode changed, and no compatibility shims are
   provided.

   For struct xtty, the dev_t tty device member was reduced to be just
   uint32_t. It was decided that maintaining ABI compatability in this
   case is more useful than reporting a 64-bit dev_t value, for the sake
   of pstat.

   Updating note: strictly follow the instructions in UPDATING. Build and
   install the new kernel with the COMPAT_FREEBSD11 option enabled, then
   reboot, and only then install the new world.

   Credits: The 64-bit inode project, also known as ino64, started life
   many years ago as a project by Gleb Kurtsou (gleb). Kirk McKusick
   (mckusick) then picked up and updated the patch, and acted as a
   flag-waver. Feedback, suggestions, and discussions were carried out by
   Ed Maste (emaste), John Baldwin (jhb), Jilles Tjoelker (jilles), and
   Rick Macklem (rmacklem). Kris Moore (kris) performed an initial ports
   investigation followed by an exp-run by Antoine Brodin (antoine).
   Essential and all-embracing testing was done by Peter Holm (pho). The
   heavy lifting of coordinating all these efforts and bringing the
   project to completion were done by Konstantin Belousov (kib).

Capability-Based Network Communication for Capsicum/CloudABI

   ARPC: GRPC-Like RPC Library That Supports File Descriptor Passing
    URL: https://github.com/NuxiNL/arpc
   Flower: A Label-Based Network Backplane
    URL: https://github.com/NuxiNL/flower

   Contact: Ed Schouten <ed@nuxi.nl>

   One of the weaknesses of Capsicum and CloudABI is that it is not easy
   to develop applications that need to make outgoing network connections,
   since system calls like connect() and sendto() are disabled. Though we
   can sometimes work around this by ensuring that the sandboxed process
   already possesses socket file descriptors on startup, this does not
   allow the destination process to be restarted, moved to a different
   network address, be load balanced, etc..

   Coming up with a solution for this is quite important for me, as I am
   currently working on making CloudABI work on top of Kubernetes,
   Google's open source cluster management suite. The idea is that
   Kubernetes will schedule CloudABI processes instead of Docker
   containers. All of these CloudABI processes will have their
   dependencies on other services in the cluster injected explicitly,
   making internal communication very secure. All of this is intended to
   work on FreeBSD as well, of course!

   To solve this problem, I've been working on a daemon called Flower
   (read: flow-er) that allows software to register services and connect
   to them. Servers are identified by a set of labels with values (e.g.,
   {datacenter: 'frankfurt', service: 'mysql'}). Clients can connect these
   servers by providing the corresponding label(s). Flower's security
   model is capability-based, just like Capsicum. The ability to bind and
   connect can be limited by permanently constraining labels to certain
   values.

   Flower has been designed not to act as a proxy. It does not copy any
   data. It merely forwards existing socket file descriptors or creates
   UNIX socket pairs and hands these out to its clients and servers. To
   realize this, processes communicate with Flower using an RPC library
   called ARPC. ARPC is a very simple clone of Google's GRPC, with the
   special feature that messages (Protobufs) can have file descriptors
   attached.

   This project was sponsored by Nuxi, the Netherlands.

   Open tasks:

    1. Finish implementing the Flower code.
    2. Integrate Flower with the Kubernetes/CloudABI runtime.
    3. Release the Kubernetes/CloudABI runtime as open source software.

Ceph on FreeBSD

   Links
   Ceph Main Site
    URL: http://ceph.com
   Main Repository
    URL: https://github.com/ceph/ceph
   My FreeBSD Fork
    URL: https://github.com/wjwithagen/ceph

   Contact: Willem Jan Withagen <wjw@digiware.nl>

   Ceph is a distributed object store and file system designed to provide
   excellent performance, reliability and scalability.
     * Object Storage
       Ceph provides seamless access to objects using native language
       bindings or radosgw, a REST interface that is compatible with
       applications written for S3 and Swift.
     * Block Storage
       Ceph's RADOS Block Device (RBD) provides access to block device
       images that are striped and replicated across the entire storage
       cluster.
     * File System
       Ceph provides a POSIX-compliant network file system that aims for
       high performance, large data storage, and maximum compatibility
       with legacy applications.

   I started looking into Ceph because the HAST solution with CARP and
   ggate did not really do what I was looking for. I aim to run a Ceph
   storage cluster of storage nodes that are running ZFS, with user
   workstations running bhyve on RBD disks that are stored in Ceph.

   Compiling for FreeBSD will now build most of the tools available in
   Ceph.

   The most important changes since the last report are:
     * Ceph has released release candidate v12.1.0 (aka Luminous); the
       corresponding packaging is sitting in my tree waiting for Luminous
       to be actually released.
     * ceph-fuse works, and allows mounting of cephfs filesystems. The
       speed is not impressive, but it does work.
     * rbd-ggate is available to create a Ceph rbd backed device.
       rbd-ggate was submitted by Mykola Golub. It works in a rather
       simple fashion: once a cluster is functioning, rbd import and
       rbd-ggate map are used to create ggate-like devices backed by the
       Ceph cluster.

   Other improvements since the previous report:
     * Some bugs in the init-ceph code (needed for rc.d) are being fixed.
     * RBD and rados are functioning.
     * The needed compatability code was written so that FreeBSD and Linux
       daemons can operate together in a single cluster.
     * More of the awkward dependancies on Linux-isms are deleted -- only
       /bin/bash is there to stay.

   The next forthcoming official release of Ceph is called Luminous
   (v12.1.0). As soon as it is available from upstream, a port will be
   provided for FreeBSD.

   To get things running on a FreeBSD system, run pkg install
   net/ceph-devel or clone https://github.com/wjwithagen/ceph, check out
   the wip.freebsd.201707 branch, and build manually by running
   ./do_freebsd.sh in the checkout root.

   Parts not (yet) included:
     * KRBD -- but rbd-ggate is usable in its stead.
     * BlueStore -- FreeBSD and Linux have different AIO APIs, and that
       incompatibility needs to be resolved somehow. Additionally, there
       is discussion in FreeBSD about aio_cancel not working for all
       device types.

   Open tasks:

    1. Run integration tests to see if the FreeBSD daemons will work with
       a Linux Ceph platform.
    2. Investigate the keystore, which can be embedded in the kernel on
       Linux and currently prevents building Cephfs and some other parts.
       The first question is whether it is really required, or if only
       KRBD requires it.
    3. Scheduler information is not used at the moment, because the
       schedulers work rather differently between Linux and FreeBSD. But
       at a certain point in time, this will need some attention (in
       src/common/Thread.cc).
    4. Improve the FreeBSD init scripts in the Ceph stack, both for
       testing purposes and for running Ceph on production machines. Work
       on ceph-disk and ceph-deploy to make it more FreeBSD- and
       ZFS-compatible.
    5. Build a test cluster and start running some of the teuthology
       integration tests on it. Teuthology wants to build its own libvirt,
       and that does not quite work with all the packages FreeBSD already
       has in place. There are many details to work out here.
    6. Design a virtual disk implementation that can be used with bhyve
       and attached to an RBD image.

DTS Updates

   Contact: Emmanuel Vadot <manu@FreeBSD.org>

   DTS (Device Tree Source) files provide a human-readable source
   description of the hardware resources for a given computer system (such
   as ARM- or MIPS-based embedded boards). The DTS source representation
   must be compiled into a binary format in order to be linked into the
   kernel and used to locate devices at runtime.

   The DTS files in FreeBSD were updated to match the versions from Linux
   4.11, to represent more modern devices and provide more accurate
   representations.

   Contact: Edward Tomasz Napiera=C5=82a <trasz@FreeBSD.org>

   Coda is a distributed file system developed as a research project at
   Carnegie Mellon University, descended from a older version of the
   Andrew File System. It got dropped from FreeBSD some five years ago,
   due to not having been adopted for a MPSAFE world. The focus for this
   current project is to bring it back into sufficiently workable shape
   that it could return to the kernel. It is currently in a working
   condition. Work is underway to test it better, fix whatever issues are
   found, and commit it to 12-CURRENT.

   This project was sponsored by Chalmers University of Technology.

   Open tasks:

    1. Additional testing.
    2. Update the userspace components (net/coda_client and
       net/coda_server).

   machines under the control of various operating systems, in particular
   FreeBSD.

   The goal of FreeBSD enablement is to provide top performance and a wide
   range of monitoring and management features such as:
     * multiple queue modes
     * hardware offloads (rx and tx checksum)
     * an admin queue
     * asynchronous notifications
     * robust hardware access
     * a scalable number of MSI-X vectors
     * hardware counters
     * watchdog mechanism
     * LRO
     * RSS

   The driver is available in the kernel source tree as of r318647.

   This project was sponsored by Annapurna Labs -- an Amazon company.

   Open tasks:

    1. Add RSS configuration from userspace (via sysctls).
    2. Add support for LLQ mechanisms.

   The ix and ixv network interface drivers support a variety of Intel
   network interfaces, with line speeds at 10 Gbit/second.

   This quarter, the drivers gained support for the X553 network
   interface, which is found on System-on-a-Chip devices based on the
   Denverton platform. This update should allow FreeBSD to be more useful
   on a new class of hardware platform.

   Work is also underway to convert these drivers to use the iflib network
   driver library, which should ease future maintenance of the drivers, as
   well as the network subsystem as a whole.

pNFS Server Plan B

   Links
   Testing Instructions
    URL: http://people.FreeBSD.org/~rmacklem/pnfs-planb-setup.txt

   Contact: Rick Macklem <rmacklem@FreeBSD.org>

   Parallel NFS (pNFS) is an extension to the NFSv4 protocol that allows
   for file accesses within a single logical mount to be performed against
   multiple file servers, with the potential for data access to occur in
   parallel. The pNFS "layout" in use specifies how the division occurs,
   with metadata operations occurring against the main server, and bulk
   data operations (read/write/setattr/etc.) occurring via a
   layout-specific scheme between the client and the data servers.

   My first attempt at a pNFS server using GlusterFS was a dud. It worked,
   but performance was so poor that it was not usable. This attempt that I
   call "Plan B", only uses FreeBSD, with one FreeBSD server handling the
   metadata operations and multiple FreeBSD servers configured to serve
   data, is now ready for third-party testing. If testing by third parties
   goes well, I anticipate the code will be merged into FreeBSD head in
   time for FreeBSD 12. Fairly recent FreeBSD or Linux systems should be
   usable as pNFS clients for testing. This server supports the File
   Layout, which is supported by both of these clients.

   There is no support for the Flex Files Layout or mirroring at this
   time. I hope to use the Flex Files Layout to add mirroring support over
   the next year or so. Striping is not supported, and I have no plans for
   implementing this at the moment.

   The patched FreeBSD sources may now be accessed for testing via either
   Subversion or download of a gzipped tarball. They consist of a patched
   kernel and nfsd and can be used on any FreeBSD 11 or later system.

   Open tasks:

    1. Testing by others will be needed, now that the code is available.

   Work proceeds to finalize the process of bringing support for the
   Marvell Armada38x platform into FreeBSD head.

   The most important parts of the recent effort are:
     * Add the network driver (NETA)
     * Enable coherent busdma operation for all ARMv7 SoCs
     * Add various low-level optimizations, such as L1 cache prefetch and
       MBUS quirks
     * Enable PL310 L2 cache controller
     * Add SDHCI support
     * Fixes for the e6000sw driver and a rework of its PHY handling

FreeBSD/arm64

   FreeBSD arm64 Wiki Page
    URL: https://wiki.FreeBSD.org/arm64

   Contact: Andrew Turner <andrew@FreeBSD.org>

   Support for the Privilege Access Never (PAN) feature was added. This
   stops the kernel from accessing userspace memory, except through
   specific instructions. This helps security by only allowing access to
   userspace via the correct accessor functions. This is enabled on all
   supported CPUs that implement ARMv8.1 or later.

   The pmap code now supports the Unprivileged execute-never (UXN) and
   Privileged execute-never (PXN) bits in the page tables. These bits stop
   userspace and the kernel, respectively, from executing instructions on
   any marked page.

   The performance of the pmap layer has been improved. Many of the cache
   handling function calls have been removed. Some were needed early on to
   work around other bugs that have now been fixed. The removal of these
   calls has led to a large performance improvement.

   The kernel now uses crc32c instructions where appropriate. These are an
   optional set of instructions to perform crc32c checksumming quickly
   without using a lookup table.c

   The VM_MEMATTR_WRITE_THROUGH memory attribute is now supported. This is
   used to allocate memory for the framebuffer. Previously, the kernel
   would use cached memory; however, this leads to visual artifacts. The
   write-through flag fixes these by writing data out to RAM.

   The default linker on arm64 is now lld. This means that FreeBSD is able
   to build itself with just the components in the base system, a big
   milestone!

   The in-tree DTC (Device Tree Compiler) was switched to use the
   BSD-licensed version by default. (The previous default DTC is licensed
   under the GPL.) The current version supports overlays and is able to
   compile every DTS (Device Tree Source) used by the FreeBSD arm
   releases. The ports GPL version was updated to the latest release
   (1.4.4). The in-tree GPL version is still present but the goal is to
   remove it before FreeBSD 12.0.

   Contact: Ed Maste <emaste@FreeBSD.org>

   LLD is the linker in the LLVM family of projects. It is a
   high-performance linker that supports the ELF, COFF and Mach-O object
   formats. It is broadly compatible with the common linkers used for each
   file format. For ELF this is the GNU Binary File Descriptor (BFD) ld
   and GNU gold. However, LLD's authors are not constrained by strict
   compatibility where it would hamper performance or desired
   functionality.

   LLD is now used as the default system linker for FreeBSD/arm64 and can
   link a working kernel, kernel modules, and userland for FreeBSD/amd64.
   LLD can also link a working kernel and modules (but not userland) for
   FreeBSD/arm and FreeBSD/i386.

   Work is ongoing to address ports that do not build with LLD as the
   system linker (either by fixing the port, or configuring the port to be
   linked by GNU ld).

   For FreeBSD 12.0 we expect to use LLD as the system linker for the same
   set of architectures that use Clang by default: 32- and 64-bit arm and
   x86.

   This project was sponsored by The FreeBSD Foundation.

   Open tasks:

    1. Fix libtool to detect LLD and pass the same command line arguments
       as for GNU ld and gold.
    2. Investigate the remaining amd64 and arm64 port build failures.
    3. Investigate and improve LLD on i386 and arm, before the creation of
       the stable/12 branch.
    4. Investigate and improve LLD on all other architectures.
    5. Extensive testing.

   Support in the Ports Collection for applications written in the Rust
   programming language that use Rust's package manager Cargo was added,
   via a new USES=3Dcargo setting. The work is based on the cargo module
   from the OpenBSD ports tree.

   This should significantly ease the porting of Rust applications, as
   previously porters had to create their own tarball of the application's
   dependencies or find other manual ways of bringing them in.

   Several new ports were added that use it, for example:
     * Alacritty, a GPU-accelerated terminal emulator
     * Exa, a modern replacement for ls
     * Ripgrep, a line-oriented search tool that combines the usability of
       The Silver Searcher with the raw speed of GNU grep

   Open tasks:

   Contact: Gerald Pfeifer <gerald@FreeBSD.org>
   Contact: Andreas Tobler <andreast@FreeBSD.org>

   The default version of GCC in the Ports Collection (the one requested
   by USE_GCC=3Dyes and various USES=3Dcompiler invocations) has been updat=
ed
   from GCC 4.9.4 to GCC 5.4.

   This new major version brings many new capabilities and improvements,
   as well as some changes that may require adjustments. The latter
   category includes many new compiler warnings, significant improvements
   to inter-procedural optimizations, and link-time optimization.

   The default mode for C is now -std=3Dgnu11 instead of -std=3Dgnu89. The =
C++
   front end has full C++14 language support, including C++14 variable
   templates, C++14 aggregates with non-static data member initializers,
   C++14 extended constexpr, and more. The Standard C++ Library
   (libstdc++) has full C++11 support and experimental full C++14 support.
   It uses a new ABI by default.

   The lang/gcc port now is a meta-port that pulls in the respective
   lang/gccX port (based on the setting of $GCC_DEFAULT) and defines gcc,
   g++, and gfortran as symlinks to the respective versioned binaries.

   This is the end of a long journey establishing this infrastructure,
   which is now similar that used by the python ports, for example. Having
   the new infrastructure makes upgrading the default, as well as locally
   adjusting the default version, a lot easier.

   gcc8-devel has been added, and armv6hf support removed, and we made
   adjustments for newer versions of FreeBSD. Also of note are various
   cleanups and changes to improve the robustness of our packages and the
   addition of support for aarch64 to many ports.

   Thanks to dim@, jbeich@, tijl@, mat@, miwi@, linimon@ for assisting
   with this work.

   Open tasks:

    1. The update of the default version of GCC from GCC 5.4 to GCC 6.4 is
       stalled, unfortunately. The work on the GCC and insfrastructure
       sides is complete, but unfortunately there are a number of broken
       ports that need to be adjusted/fixed. Any help is very appreciated;
       see PR 219275 for details.

   The FreeBSD GNOME Team maintains the GNOME, MATE, and CINNAMON desktop
   environments and graphical user interfaces for FreeBSD. GNOME 3 is part
   of the GNU Project. MATE is a fork of the GNOME 2 desktop. CINNAMON is
   a desktop environment using GNOME 3 technologies but with a GNOME 2
   look and feel.

   After a period of not much activity, this quarter we started a little
   experiment in how we merge ports from the development repo to the
   FreeBSD Ports Collection. Instead of merging everything in one big
   commit, we have been updating the GNOME ports one at a time or in small
   groups. For example, the GTK+ stack and the Evolution Suite were
   updated as groups, and all the gnome-games components were done in one
   commit. It might be a bit more work preparing and testing the updates,
   but on the plus side, it easy to keep track of what is going on, and
   allows us to pay attention to the details. It should also make it
   easier to commit smaller changes.

   This quarter started with the update of GTK+ 3 to 3.22.15, and the
   underlying libraries to their latest stable versions. After the GTK+
   update, work started on getting newer versions of other GNOME
   applications updated.

   The webkit2-gtk3 port was first updated to the 2.14 series and later to
   2.16.3, which is the latest stable version. This step was needed
   because 2.16 couldn't be built on FreeBSD 10.3 without some required
   framework changes.

   harfbuzz-icu was split off from the main harfbuzz port. This drops the
   heavy icu dependency from the main harfbuzz port.

   A longstanding GLib/gio bug was fixed that had previously caused
   crashes of gnome-shell and other applications when share/applications
   was modified, as happens on pkg install or deinstall.

   Many of these updates are based on work previously done in the Gnome
   development branch by Ruslan Makhmatkhanov, Gustau Perez and Koop Mast.

   Open tasks:

    1. Porting of Mutter/Gnome-shell/GDM 3.24 is complete. Unfortunately,
       GDM is blocking the update because of a "handoff" bug to the
       session after login.
    2. Fix the printer submenu in gnome-control-center. As a workaround,
       system-config-printer can be used to configure printers.
    3. MATE 1.18 is being QA tested and should arrive in early July.

   KDE's official continuous integration (CI infrastructure).

   After the X.Org and GNOME ports teams, the KDE on FreeBSD team has
   moved its development repository to GitHub. This should make it easier
   for others to collaborate with us via pull requests, and by basing all
   our changes on top of the official ports tree we also hope this reduces
   the amount of conflicts and churn we need to deal with when landing big
   updates across the tree. We would like to thank iXsystems for hosting
   and supporting our area51 Subversion repository for many years.

   FreeBSD has finally joined KDE's CI (Continuous Integration) system as
   a tier-1 platform. KDE CI builds all the KDE sources -- 70 frameworks,
   the KDE Plasma Desktop and a plethora of KDE Applications --
   continuously, straight from KDE's git repositories. There is strong
   commitment from upstream and the downstream KDE-FreeBSD team to reduce
   the amount of patching in the KDE ports to as little as possible. The
   first effects are being felt in expanding the set of unit tests to
   include FreeBSD-specific situations, and in extending Qt to handle
   FreeBSD filesystems better. In addition to the KDE sysadmins, we would
   also like to extend our thanks to Adriaan de Groot, who is both a KDE
   committer and part of our KDE on FreeBSD team, for spearheading these
   efforts.

   The following big updates landed in the ports tree this quarter:
     * CMake was updated to 3.8.0 and 3.8.2
     * KDE Frameworks was updated to 5.33, 5.34 and 5.35
     * The Calligra office suite was updated to 3.0.1, the first release
       in the ports tree to be based on KDE Frameworks 5, and the latest
       stable release upstream
     * The Konversation IRC client was updated to 1.7.2, the latest
       upstream release and the first ports version based on KDE
       Frameworks 5
     * KchmViewer was updated to 7.7, which is based on KDE Frameworks 5
     * LabPlot was updated to 2.3.0 and 2.4.0, and is now based on KDE
       Frameworks 5
     * QtCreator was upated to 4.2.2 and subsequently to 4.3.0
     * py-sip was updated to 4.19.2, PyQt4 to 4.12 and PyQt5 to 5.7.1
     * Several fixes for ARMv6 landed in the Qt4 and Qt5 ports -- thanks
       to Mika=C3=ABl Urankar

   After several review rounds and exp-runs, Tobias Berner (tcberner@)
   finally made the Ninja generator the default for CMake-based ports, so
   that devel/ninja is used instead of (g)make in most cases. This should
   make most builds faster, even if only by a small margin. Adriaan de
   Groot also wrote a blog post about the change.

PHP Ports: Help Improving QA

   Links
   My Patreon Page
    URL: https://www.patreon.com/TorstenZuehlsdorff

   Contact: Torsten Z=C3=BChlsdorff <tz@FreeBSD.org>

   As maintainer of the PHP ports, I first want to thank you all for the
   great feedback and patches I receive, in many forms. You keep my life
   interesting!

   In the past few months I learned a lot about various configurations,
   settings and bugs. Also, sadly, there are always PRs, patches and
   emails left unanswered, because of missing time on my side.

   I want to improve the situation by adding more automatic QA testing,
   but I need help to do so. Please send me your non-standard
   PHP-configurations or describe your exotic setups! These can be as
   simple as changed default versions, like LibreSSL instead of OpenSSL or
   the GCC version used for compiling. I, for example, always use another
   PostgreSQL-version than the default (and always PHP 7.1). Of course,
   this also covers port options set in an non-default way or setups that
   change variables to allow for multiple PHP installations, etc..

   I plan to test on all supported FreeBSD versions, so you only need to
   mention if you are using an unsupported version.

   Note: Since PHP 7.2 is coming (hopefully on schedule), I will test PHP
   7.2 from the onset with all the provided configurations, too.

   Open tasks:

    1. Document the various configurations to be tested.
    2. Setup the automatic QA infrastructure.

   Rust was updated to 1.18.0 and Cargo to 0.19.0, the latest versions at
   the time of this writing.

   lang/rust was enabled on FreeBSD/aarch64 and work has continued on
   devel/cargo to achieve the same. We are also making slow progress to
   add support for even more platforms.

   Discussion has started upstream to support API/ABI-breaking changes
   between major releases of operating systems. For instance, this is
   required to be able to target both FreeBSD 11.x and 12.x, which have
   ABI changes involving important structures. Once support is added
   upstream, it will be possible to target a specific ABI and do
   cross-compilation.

   lang/rust-nightly was marked as broken for now. We need to revisit how
   the port is built so we can use the x.py script as recommended by
   upstream.

   Tobias Kortkamp (tobik@) created the USES=3Dcargo setting to make it easy
   to add Rust applications to the Ports Collection. This is further
   detailed in a separate entry in this quarterly status report.

   The compiler, rustc, is crashing sometimes when there is a compilation
   error. Therefore, there is a bit of work to do to improve its
   stability.

   There is some code duplication between the lang/rust* and devel/cargo
   Makefiles. These all deserve a bit of cleanup, and it might be useful
   to create a USES=3Drust Makefile helper.

   Open tasks:

    1. Bootstrap Rust on more platforms.
    2. Investigate compiler crashes.
    3. Investigate how to speed up lang/rust* compilation times.

   sndio is a small audio and MIDI framework that is part of the OpenBSD
   project. It provides a lightweight audio and MIDI server, sndiod. It
   currently supports OpenBSD, FreeBSD, DragonFly BSD, and Linux.

   The porting effort to FreeBSD and OSS started last year and the sndio
   backend support in the FreeBSD Ports Collection can now be considered
   good enough for daily use.

   Sndio offers network transparency through sndiod, which provides an
   easy way to share your audio devices with other machines/VMs/jails on
   your network. However, applications and libraries need to support
   playing and recording through it. To that end, I submitted several
   patches to various ports over the course of the last year.

   Here's a short selection of ports that now support sndio in the FreeBSD
   Ports Collection:
     * Most games, via audio/openal-soft, devel/sdl12, and devel/sdl20.
     * GStreamer-based applications and WebKit-based browsers through two
       new GStreamer plugins (audio/gstreamer1-plugins-sndio and
       audio/gstreamer-plugins-sndio).
     * Firefox, Firefox ESR, Seamonkey, Chromium, and Iridium. The
       browsers currently lack or have a non-functional OSS backend. Sndio
       support provides a BSD-native alternative to the ALSA and
       PulseAudio backends.
     * Video players like VLC, Totem, mpv, mplayer, etc..
     * Audio players like Clementine, cmus, mpd, mpg123, siren, xmp, etc..
     * SoX.
     * Shairport Sync, through a newly implemented backend.
     * JACK.
     * PulseAudio, through audio/pulseaudio-module-sndio.

   Open tasks:

    1. Commit a backport of Kodi's new sndio backend to the Ports
       Collection.
    2. If you maintain or use an audio-related port, consider checking
       whether it includes an sndio backend, and adding an SNDIO option.
       Thanks to the OpenBSD developers, several open-source projects
       already include one, so adding it might be very easy to do.

   As described on its website, "TensorFlow(TM) is an open source software
   library for numerical computation using data flow graphs. Nodes in the
   graph represent mathematical operations, while the graph edges
   represent the multidimensional data arrays (tensors) communicated
   between them. The flexible architecture allows you to deploy
   computation to one or more CPUs or GPUs in a desktop, server, or mobile
   device with a single API. TensorFlow was originally developed by
   researchers and engineers working on the Google Brain Team within
   Google's Machine Intelligence research organization for the purposes of
   conducting machine learning and deep neural networks research, but the
   system is general enough to be applicable in a wide variety of other
   domains as well."

   TensorFlow now is the most popular platform/library for machine
   learning and AI. There are official binaries for Linux, Mac, Windows,
   and Android, but no official support for FreeBSD. For the last several
   months, I have done some work to make TensorFlow available on FreeBSD.
   Some notable items include:
     * bazel was patched to not depend on /proc at build time. bazel is a
       build tool made by Google. It uses /proc to get path-to-self when
       building C++ code, but mounting /proc is usually not allowed when
       building as an unprivileged user.
     * TensorFlow can now be built on FreeBSD 10.x by using clang38 as the
       default bazel cross-build tool.
     * Patch the bazel workspace files to allow TensorFlow to be built
       using offline third-party dependencies. This work is needed because
       the FreeBSD Ports framework does not allow network access except
       during the fetch stage.
     * Fix the build on FreeBSD i386.
     * Make TensorFlow build with either Python 2 or Python 3.
     * Update to the latest version, which is tensorflow-1.2.0.

   TensorFlow can now be run on FreeBSD in CPU-only mode. Some functional
   tests have been performed on some combinations of FreeBSD 10.3-RELEASE
   and 11.0-RELEASE, amd64 and i386, and Python 2.7 and Python 3.6.

   This port would not be possible without substantial assistance from
   bapt@, lwhsu@, mat@, and koobs@ -- thank you for your advice, review,
   and help! You are very nice and I learned a lot about FreeBSD and the
   Ports framework from you.

   Open tasks:

    1. Review, test, comment, and most importantly, commit to the Ports
       Collection.
    2. Fix OpenCL (GPU acceleration) support on FreeBSD.
    3. Port tensorflow-serving, which is a flexible, high-performance
       serving system for machine learning models produced by TensorFlow.
    4. Set up a CI for TensorFlow on FreeBSD and give early notice to
       upstream when they break TensorFlow on FreeBSD.

Updating Port Metadata for non-x86 Architectures

   Contact: Mark Linimon <linimon@FreeBSD.org>

   I have been analyzing the error logs from ports builds for all non-x86
   architectures, including both the logs published on the package build
   cluster and also other builds of powerpc64 and sparc64.

   From this analysis, I have marked almost all the failing ports as
   either BROKEN or NOT_FOR/ONLY_FOR, as appropriate.

   The intent of this work is not to make life harder for anyone, but
   rather, in fact, the opposite. With these definitions in place, it is
   possible to scan the poudriere bulk build output (the "Ignored ports"
   portion, in particular) and see quickly what ports are failing to build
   and why. Previously, finding the exact reason why a build failed needed
   some research (portsmon only analyzes failure messages on amd64).
   Additionally, it is extremely difficult to work through several hundred
   logs that simply say "failed to compile", "failed to link", and so forth.

   This is part of an effort to identify where we need further work to
   bring sufficient Ports Collection support to, e.g., armv6 and aarch64
   to bring them closer to true Tier-1 status.

   To further facilitate locating patterns in the Poudriere output, I have
   begun reworking some existing BROKEN/NOT_FOR/ONLY_FOR messages so that
   they will sort more easily. This includes sorting the order in which
   architectures appear in the lists.

   Many people have been doing great work on fixing the individual ports.
   I hope that my work makes their jobs somewhat easier.

   Xfce is a free software desktop environment for Unix and Unix-like
   platforms such as FreeBSD. It aims to be fast and lightweight, while
   still being visually appealing and easy to use.

   During this quarter, we have kept these applications up-to-date:
     * audio/xfce4-pulseaudio-plugin (0.2.5, PR219357)
     * deskutils/xfce4-tumbler (0.1.32, PR219848)
     * deskutils/xfce4-xkb-plugin (0.8.0, PR220071)
     * sysutils/garcon (0.6.1, PR219928, and PR219334 for Mk/Uses/xfce.mk)
     * textproc/xfce4-dict-plugin (0.8.0, PR220266)

     * x11-wm/xfce4-desktop (4.12.4, PR220290)

   We have created a new Subversion tag (4.13) in order to follow the
   unstable releases. The separate tag was necessary in order to support
   changes in the USES=3Dxfce infrastucture, and due to some incompatible
   changes to the xfconf API. Ports following the unstable release are:
     * deskutils/xfce4-tumbler (0.1.92.1)
     * multimedia/xfce4-parole (0.9.2)
     * sysutils/xfce4-settings (4.13.1)

Doc Version Strings Improved by Their Absence

   Contact: Warren Block <wblock@FreeBSD.org>

   In retrospect, our $FreeBSD$ strings in source files are kind of weird,
   like a vestigial tail. The version control system stores all of that
   information in metadata. Yet here we are, not only allowing the version
   control system to alter our source files on every commit, but forcing
   it to do so.

   The reason for doing so is that the previous version control system did
   it. Really.

   Version control strings are a headache for translators using the new PO
   toolchain. It is an ever-changing string that offers nothing to the
   translation, yet can cause conflicts with earlier versions of itself.

   We also had complaints about how the Handbook was always months out of
   date. It was not, of course... but looking at just the version string
   in the main, rarely-changing book.xml file gave that impression. We
   fixed that problem last year, so the build system checks all the source
   files for the latest commit, but it seems easier to not have to fix the
   problem at all.

   Of course, that was really only one aspect of an ongoing problem. Our
   documentation build system was checking the version string in the
   source file, not the metadata. In 1973, metadata, like cars not
   composed chiefly of rust, had not yet been invented. I modified the
   build system to extract the information from the metadata (and noted,
   with some surprise, that this is a task at which Git is much better
   than Subversion).

   The next step was to remove the $FreeBSD$ strings from the source files
   and remove the FreeBSD=3D%H property that forces Subversion, against its
   better judgement, to substitute text in the actual contents of the
   file. The version information is not lost. It lives in the metadata, so
   retrieving it is as simple as svn info -- it does not need to be in the
   source at all. However, as with anything that touches code or processes
   which have not been touched in living memory, there was some debate
   over this. At that point, I offered to remove the version strings from
   the FreeBSD Documentation Project Primer book as a test.

   The change allowed the zh_TW translation team to turn off the
   FreeBSD=3D%H property on their translation and continue their work
   without fighting with the version strings. Rendered versions of the
   book still display the name of the last committer and the date and
   revision number of the last commit, but all of that information comes
   from metadata. As such, it is also more likely to be correct.

   Since the change, there have not been any complaints, at least not to
   me. In fairness, the removal of version strings from the FDP Primer
   alone is a small change in a tiny corner of the project. Looking at it
   another way, it might be that some things that seem to be necessary are
   more about the comfort of familiarity than actual utility.

   At present, this is strictly a change to the documentation build
   toolchain and a single documentation book. However, there do not appear
   to be any reason why it could not be extended to the rest of the
   documents. It might even serve as tiny test of whether the expansion of
   $FreeBSD$ tags is needed throughout the rest of the FreeBSD tree.

   FreeBSD supports the Xen hypervisor, with DomU (guest) support since
   FreeBSD 8.0 and Dom0 (host) available since FreeBSD 11.0. The FreeBSD
   Handbook was lacking instructions on how to run a Xen host and VMs. The
   steps were outlined in the FreeBSD wiki, but needed some extra bits of
   text from the upstream Xen wiki in order to form a complete guide. The
   new handbook section briefly explains what Xen is, how it differs from
   other hypervisors, and what features are currently available in
   FreeBSD. It then goes on to describe how to set up the Dom0, as well as
   detailing the guest VM support known as DomU.

   Reviewers Nikolai Lifanov, Roger Pau Monn=C3=A9, and Warren Block provid=
ed
   valuable feedback on the initial version in Phabricator. Additional
   corrections were made by Bj=C3=B6rn Heidotting while translating the sec=

   Open tasks:

    1. More options for the Dom0 and DomU could be provided.
    2. People should test these instructions on their hardware and provide
       feedback. This would also help us get better testing of the Xen
       port for FreeBSD.

   presentations on multiple subjects: the non-technical history of
   FreeNAS (presented by olivier@), how OVH is using ZFS, an introduction
   to jails, and a use case for BGP/bird on FreeBSD.

   The second meetup, also hosted in the OVH office, presented these
   subjects: how to create a FreeBSD port (presented by jadawin@), how OVH
   is using Finite State Machines for managing their storage system,
   network high-availability with FreeBSD, and a jail tutorial by means of
   a demonstration running 200 OSPF (using net/bird) routers using jails
   and vnets on a small PC Engines APU2 system with only 4 CPU cores (1Ghz
   AMD) and 4GB RAM).

   This project was sponsored by OVH.

   HardenedBSD is a derivative of FreeBSD that gives special attention to
   security-related enhancements and exploit-mitigation technologies. From
   an initial focus on Address Space Layout Randomization (ASLR), it has
   now branched out to explore additional exploit mitigation techniques.

   It has been a long while since HardenedBSD's last entry in a quarterly
   status report, back in 2015Q4. The intervening year saw HardenedBSD
   gain new developers Bernard Spil and Franco Fichtner, import LibreSSL
   and OpenNTPd into base as the default crypto library and NTP client,
   respectively, and introduce the hbsd-update binary update mechanism for
   the base system. The secadm application got a rewrite and Trusted Path
   Execution (TPE). PIE is now enabled for the base system for arm64 and
   amd64 as well as the bulk of the ports tree, and the ports tree also
   gained RELRO and BIND_NOW. Integriforce (similar to NetBSD's verified
   exec, veriexec) was introduced for the base system, as well as
   SafeStack, a technology for protection against stack-based buffer
   overflows that's developed by the Clang/LLVM community. SafeStack
   relies and builds on top of Address Space Layout Randomization (ASLR),
   and is strengthened by the presence of PaX NOEXEC. Certain high-profile
   ports also have SafeStack enabled.

   Extremely generous hardware donations from G2, Inc. have provided for
   dedicated package building and binary update servers, as well as
   development and test servers.

   In March of 2017, we added Control Flow Integrity (CFI) to the base
   system. CFI is an exploit mitigation technique that helps prevent
   attackers from modifying the behavior of a program and jumping to
   undefined or arbitrary memory locations. This type of technique is
   gaining adoption across the industry -- Microsoft has implemented a
   variant of CFI, which they term Control Flow Guard, or CFG, and the PaX
   team has spent the last few years perfecting their Reuse Attack
   Protector, RAP. Of these, RAP is the most complete and effective
   implementation, followed by Clang's CFI. RAP would be a great addition
   to HardenedBSD; however, it requires a GPLv3 toolchain and is
   patent-pending.

   CFI can be implemented either on a per-DSO basis, or across all DSOs in
   a process. Currently only the former is implemented, but we are working
   hard to enable cross-DSO CFI. As is the case for SafeStack, cross-DSO
   CFI requires both ASLR and PaX NOEXEC in order to be effective. If an
   attacker knows the memory layout of an application, the attacker might
   be able to craft a data-only attack, modifying the CFI control data.

   The behavior of several system control (sysctl) nodes has been tighened
   up, limiting write access and introducing additional safety checks for
   write accesses. Kernel module APIs received a similar treatment.
   HardenedBSD's PaX SEGVGUARD implementation received a few updates to
   make it more stable and performant.

   As of March 2017, HardenedBSD is now accessible through a Tor hidden
   service. The main website, binary updates, and package distribution are
   all available over the hidden service.

   We now maintain our own version of the drm-next branch for updated
   graphics support. Binary updates are also provided for this branch.

   HardenedBSD would like to thank all those who have generously donated
   time, money, or other resources to the project.

   This project was sponsored by SoldierX, and G2, Inc.

   Open tasks:

    1. Port SafeStack to arm64.
    2. Integrate Cross-DSO CFI.
    3. Add documentation to the HardenedBSD Handbook.
    4. Start porting grsecurity's RBAC.
