The first quarter of 2016 showed that FreeBSD retains a strong sense of ipseity. Improvements were pervasive, lending credence to the concept of meliorism.

Panegyrics are relatively scarce, but not for lack of need. Perhaps this missive might serve that function in some infinitesimal way.

There was propagation, reformation, randomization, accumulation, emulation, transmogrification, debuggenation, and metaphrasal during this quarter.

In the financioartistic arena, pork snout futures narrowly edged out pointilism, while parietal art remained fixed.

In all, a discomfiture of abundance. View the rubrics below, and marvel at their profusion and magnitude! Marvel!

—Warren Block

Please submit status reports for the second quarter of 2016 by July 7. A thesaurus will be provided for submitters who do not have one of their own. We will need them back afterwards, preferably with no new teeth marks on the covers. Thank you!

    The FreeBSD Core Team

    Contact: FreeBSD Core Team <>

    During the first quarter of 2016, the most important business of the FreeBSD Core Team has been to respond to the harassment incident last year. Core's actions were to assemble a timeline of the events and in the light of that to review Core's actions at the time; and to make recommendations about how better to handle such cases in future. During this process, draft reports were reviewed by people concerned in the case and in addition a number of interested members of the FreeBSD community. Core would like to thank everyone involved for their contributions.

    The report was published to the FreeBSD developer community in mid-February, and contained six recommendations for the community to consider.

    Core is also coordinating with the committee headed by Anne Dickison who are reviewing the Code of Conduct. A corpus of case studies is being assembled, which will be re-examined to see what impact changes to the Code of Conduct would have had.

    Core, together with John Baldwin, are working on a plan to create a separate repository containing GPLv3 toolchain components. This will allow modernization of code within base beyond what the existing GPLv2 toolchain can handle, and permit support of certain new architectures where a copyfree licensed alternative (i.e., LLVM) is not yet available. A position paper will soon be circulated to developers for comment.

    During this quarter three new commit bits were issued, and one was returned for safekeeping. Please welcome Wojciech Macek, Jared McNeil and Stanislav Galabov, and bid farewell to Davide Italiano, who although too busy to work on FreeBSD directly, will still be contributing through his work upstream on lld and other parts of the toolchain.


    Address Space Layout Randomization

    Patch Home URL:
    paxtest.log URL:
    fedora.log URL:

    Contact: Konstantin Belousov <>
    Contact: Ed Maste <>

    I wrote a small and straightforward yet feature-packed patch to implement ASLR for FreeBSD which is now available for broader testing.

    With this change, randomization is applied to all non-fixed mappings. By randomization, I mean that the base address for the mapping is selected with a guaranteed amount of entropy (bits). If the mapping was requested to be superpage aligned, the randomization honors the superpage attributes.

    The randomization is done on a best-effort basis. That is, the allocator falls back to a first fit strategy if fragmentation prevents entropy injection. It is trivial to implement a strong mode where failure to guarantee the requested amount of entropy results in failure of the mapping request failure, but I do not consider that to be usable.

    I have not fine-tuned the amount of entropy injected right now, but that is only a quantitive change that will not change the implementation. The current amount is controlled by aslr_pages_rnd.

    To not spoil coalescing optimizations, to reduce the page table fragmentation inherent to ASLR, and to retain transient superpage promotion for malloced memory, locality is implemented for anonymous private mappings, which are automatically grouped until fragmentation kicks in. The initial location for the anon group range is, of course, randomized. After some additional tuning, the measures appeared to be quite effective. In particular, a very address-space-hungry build of PyPy 5.0 on i386 successfully finished with the most aggressive functionality of the patch activated.

    The default mode keeps the sbrk area unpopulated by other mappings, but this can be turned off, which gives much more breathing room on the small address-space architectures (it is funny that 32 bits is now considered small). This is tied with the question of following an application's hint about the mmap(2) base address. Testing shows that ignoring the hint does not affect the function of common applications, but I would expect that more demanding code could break. By default sbrk is preserved and mmap hints are satisfied, which can be changed by using the kern.elf{32,64}.aslr_care_sbrk sysctls (currently enabled by default for wider testing).

    Stack gap, W^X, shared page randomization, KASLR and other techniques are explicitly out of scope for this work.

    The paxtest results for the run with the previous version 5 of the patch applied and aggressively tuned can be seen at paxtest.log. For comparison, a run on Fedora 23 on the same machine is at fedora.log.

    ASLR is enabled on a per-ABI basis, and currently is only enabled on native i386 and amd64 (including compat 32-bit) and ARMv6 ABIs. I expect to test and enable ASLR for arm64 as well, later.

    A procctl(2) control for ASLR is implemented, but I have not provided a userspace wrapper around the syscall. In fact, the most reasonable control needed is per-image and not per-process, but we have no tradition to put the kernel-read attributes into the extattrs of a binary, so I am still pondering that part and this also explains the non-written tool.

    Thanks to Oliver Pinter and Shawn Webb of the HardenedBSD project for pursuing ASLR for FreeBSD. Although this work is not based on theirs, it was inspired by their efforts.

    Thanks to Ed Maste, Robert Watson, John Baldwin, and Alan Cox for some discussions about the patch, and for The FreeBSD Foundation for directing me.

    Bartek Rutkowski tested PyPy builds on i386, and David Naylor helped with the port which was at the point of turbulence and upgrade during the work.

    Ceph on FreeBSD

    Ceph Main Site URL:
    Main Repository URL:
    My Fork URL:
    The git pull with All Changes URL:

    Contact: Willem Jan Withagen <>

    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 wanted. But I am aiming for running a Ceph storage cluster of storage nodes that are running ZFS. The end station would be running bhyve on RBD disk that are stored in Ceph.

    The FreeBSD build will build most of the tools in Ceph. Note that the RBD-dependent items will not work since FreeBSD does not have RBD yet.

    Compiling and building Ceph is tested on 11-CURRENT. It uses the Clang toolset that is available, which needs to be at least 3.7. Clang 3.4 (on 10.2-STABLE) does not have all the required capabilities to compile everything.

    This setup will get things running for FreeBSD:

    • Install bash and link it in /bin (requires root privileges):

      sudo pkg install bash

      sudo ln -s /usr/local/bin/bash /bin/bash

    • Building Ceph

      git clone

      cd ceph

      git checkout wip-wjw-freebsd-tests


    Parts Not Yet Included:

    • RBD

      Rados Block Devices is implemented in the Linux kernel. It seems that there used to be a userspace implementation first. And perhaps ggated could be used as a template since it does some of the same functions, other than just between two disks. And it has a userspace counterpart.

    • BlueStore

      FreeBSD and Linux have a different AIO API, and that needs to be made compatible. Next to that is the discussion in FreeBSD about aio_cancel not working for all device types.

    • CephFS

      Cython tries to access an internal field in dirent which does not compile.

    Tests that verify the correct working of the above are also excluded from the test set.

    Tests Not Yet Included:

    • ceph-detect-init/

      Because the current implementation does not know anything about FreeBSD's rc/init.

    • Tests that make use of nosestests

      Calling these does not really work since nosetests is not in /usr/bin, and calling through /usr/bin/env nosetests does not work on FreeBSD.

    • test/pybind/

    • test/pybind/

    Things To Investigate:

    • ceph-{osd,mon} need two signals before they actually terminate.

    • ceph_erasure_code --debug-osd 20 --plugin_exists jerasure crashes due to SIGSEGV. This is a pointer reference that gets modified outside the regular programflow. Probably due to a programming error but perhaps wrong mixing and matching of many libraries.

    Open tasks:

    1. The current and foremost task is to get the test set to complete without errors. This includes fixing several coredumps.

      Run integration tests to see if the FreeBSD daemons will work with a Linux Ceph platform.

    2. Get the Python tests that are currently excluded to work, and test OKE.

    3. Compile and test the user space RBD (Rados Block Device).

      Investigate and see if an in-kernel RBD device could be developed akin to ggate.

    4. Integrate the FreeBSD /etc/rc.d init scripts in the Ceph stack for testing and running Ceph on production machines.

    Process-Shared Locks for libthr

    Contact: Konstantin Belousov <>

    POSIX specifies several kinds of pthread locks. For this report, the private and process-shared variants are considered. Private locks can be used only by the threads of the same process, which share a single common address space. Process-shared locks can be used by threads from any process, assuming the process can map the lock memory into its address space.

    Our libthr, the library implementing the POSIX threads and locking operations, uses a pointer as the internal representation behind a lock. The pointer contains the address of the actual structure carrying the lock. This has unfortunate consequences for implementing the PTHREAD_PROCESS_SHARED attribute for locks, since really only the pointer is shared when a lock is mapped into distinct address spaces.

    A common opinion was that we have no choice but to break the libthr Application Binary Interface (ABI) by changing the lock types to be the actual lock structures (and padding for future ABI extension). This is very painful for users, as our previous experience with non-versioned libc and libc_r has shown.

    Instead, I proposed and implemented a scheme where process-shared locks can be implemented without breaking the ABI. The lock memory is used as a key into a system-global hash of shared memory objects (off-pages), which contain the actual lock structures.

    New umtx operations to create or look up a shared object by memory key were added. libthr is modified to look up the object and use it for shared locks, instead of using malloc() as for private locks.

    The pointer value in the user-visible lock type contains a canary for shared locks. libthr detects the canary and switches into the shared-lock mode.

    The proposal of inlining the lock structures, besides the drawbacks of breaking ABI, has its merits. Most important, the inlining avoids the need for indirection. Another important advantage over the off-page approach is that no off-page object needs to be maintained, and the lifecycle of the shared lock naturally finishes with the destruction of the shared memory, without need for explicit cleanup. Right now, off-pages hook into vm object termination to avoid leakage, but long-livedness of the vnode vm object prolongs the off-page's existence for shared locks backed by files, however unlikely they may be.

    libthr with inlined locks became informally known as the libthr2 project, since it is better to change the library name than just bumping the library version. rtld should ensure that libthr and libthr2 are not simultaneously loaded into a single address space.

    This project was sponsored by The FreeBSD Foundation.

    Open tasks:

    1. Implement robust mutexes.

    2. Evaluate and implement libthr2.

    RCTL Disk IO Limits

    Contact: Edward Tomasz Napierała <>

    An important missing piece of the RCTL resource limits framework was the ability to limit file system throughput. This project aims to fill that hole by making it possible to add RCTL rules for read bytes per second (BPS), write BPS, read I/O operations per second (IOPS), and write IOPS, and adding a new throttling mechanism to slow down offending processes when a limit gets hit.

    The code has been committed and will ship with FreeBSD 11.0-RELEASE.

    This project was sponsored by The FreeBSD Foundation.

    Open tasks:

    1. Additional testing

    2. Simplify locking, getting rid of rctl_lock altogether

    3. Improve statistics gathering by making it possible for rctl -u to retrieve usage counters at a fixed point in time

    4. Use the new throttling mechanism for %CPU limits

    Contact: FreeBSD Graphics team <>

    The major news for this quarter is the update of the i915 driver in the kernel! The driver now matches Linux 3.8.13, so it includes initial Haswell support. Linux 3.8 is already three years old, but work continues to upgrade DRM further. In particular, work commenced to move to using the linuxkpi compatibility.

    In the Ports tree, Mesa was updated to 11.1.2. The next minor release, 11.2.0, is ready for testing in our development tree. We also updated libclc to, a library used by Mesa to provide OpenCL support. Upstream patches were added to beignet so all these ports now use the same LLVM version.

    We attended FOSDEM 2016 in Brussels. Jean-Sébastien Pédron gave a talk to explain the work of the graphics team and show how people can contribute. It was well received and the presentation was followed by interesting discussions. FOSDEM was also a nice occasion to meet and talk again to the nice upstream developers of the graphics stack.

    For the first year, we added two ideas for GSoC 2016: one for a kernel task, one to redesign libdevq. Six students submitted proposals for those ideas; that was unexpected! We now need to decide which one we want to mentor and the choice is difficult.

    Our blog has moved to a new location (linked above).

    Open tasks:

    1. See the "Graphics" wiki page for up-to-date information.

    CAM I/O Scheduler

    I/O Scheduling in FreeBSD's CAM Subsystem (PDF) URL:
    The BSDCan 2015 Talk URL:

    Contact: Warner Losh <>

    An enhanced CAM I/O scheduler has been committed to the tree. By default, this scheduler implements the old behavior. In addition, an advanced adaptive scheduler is available. Along with the scheduler, SATA disks can now use Queued Trims with devices that support them. Details about the new scheduler are available in the I/O Scheduling in FreeBSD's CAM Subsystem article (PDF) or from the BSDCan 2015 talk.

    The adaptive I/O scheduler is disabled by default, but can be enabled with options CAM_ADAPTIVE_IOSCHED in the kernel config file. This scheduler allows favoring reads over writes (or vice versa), controlling the IOPs, bandwidth, or concurrent operations (read, write, trim), and permits the selection of static or dynamic control of these operations. In addition, a number of statistics are collected for drive operations that are published via sysctl. One advanced use for the adaptive I/O scheduler is to compensate for deficiencies in some consumer-grade SSDs. These SSDs exhibit a performance cliff if too much data is written to them too quickly due to internal garbage collection. Without the I/O scheduler, read and write performance drop substantially once garbage collection kicks in. The adaptive I/O scheduler can be configured to monitor read latency. As read latency climbs, the I/O scheduler reduces the allowed write throughput, within limits, to attempt to maximize read performance. A simple use of the adaptive I/O scheduler would be to limit write bandwidth, IOPs or concurrent operations statically.

    Future work on the I/O scheduler will be coupled with improvements to the upper layers. The upper layers will be enhanced to communicate how urgent I/O requests are. The I/O scheduler will inform the upper layers of how full the I/O queues are, so less urgent I/O can be submitted to the lower layers as quickly as possible without overwhelming the lower layers or starving other devices of requests.

    FDT Overlay Support in UBLDR

    ubldr Patch URL:

    Contact: Oleksandr Tymoshenko <>

    A flattened device tree is a way to keep the hardware description separated from code. During the boot process, the loader passes a pointer to the device-tree blob to the kernel and the kernel instantiates and attaches drivers according to the information in the blob.

    This approach does not work when the hardware is expandable. For example, the Raspberry Pi and Beaglebone Black have the concept of capes or shields: snap-on PCBs that are connected to IO headers on the main board and provide additional functionality like an LCD screen or GPS receiver. These shields can be described by their own device trees and these trees can be overlaid on the base tree by the boot loader, thus providing an accurate description to the kernel.

    The proposed patch adds this functionality to ubldr. The user can specify a comma-separated list of overlays to U-Boot or the loader fdt_overlays variable and ubldr will load them from the /boot/dtb/ directory and do the overlaying.

    Filemon Performance/Stability Improvements

    Contact: Bryan Drewery <>
    Contact: Mateusz Guzik <>

    Filemon is a kernel module for tracing which files a command creates, reads, writes, or executes. It allows tracking build dependencies in combination with bmake's meta mode. bmake stores filemon's output in a .meta file along with the build command and later uses this to trigger a rebuild of the target if any of the files referenced are missing or modified, or if the build command changes. It provides the same functionality as the compiler's -MF flag, but for everything. It will be critical for buildworld's WITH_META_MODE (which is the normal buildworld but only using filemon) to provide a reliable incremental build without even the need for .depend files or compiler -MF flags. This allows -DNO_CLEAN to work all of the time.

    Filemon on -HEAD was improved for stability and performance over this quarter. It no longer causes every syscall it hooks into to loop over processes looking for a matching filemon struct. It now just attaches directly to the struct proc with its own pointer. This improves performance by reducing lock contention during a build. Much other work went into improving error handling and other stability issues in the module as well.

    All of this work was done by Bryan Drewery, sponsored by EMC, but much help and identification of bugs was provided by Mateusz Guzik.

    This project was sponsored by EMC / Isilon Storage Division.

    Open tasks:

    1. Improve credential handling.

    2. Improve EVENTHANDLER performance.

    3. Possibly provide a framework for syscallenter/syscallret hooking to avoid the need to hook syscalls as Filemon does.

    FreeBSD Integration Services (BIS)

    FreeBSD Virtual Machines on Microsoft Hyper-V URL:
    Supported Linux and FreeBSD Virtual Machines for Hyper-V on Windows URL:

    Contact: Sepherosa Ziehau <>
    Contact: Howard Su <>
    Contact: Hongjiang Zhang <>
    Contact: Dexuan Cui <>

    When FreeBSD virtual machines (VMs) run on Hyper-V, using Hyper-V synthetic devices is recommended to get the best network and storage performance and make full use of all the benefits that Hyper-V provides. The collection of drivers that are required to use Hyper-V synthetic devices in FreeBSD are known as FreeBSD Integration Services (BIS). Some of the BIS drivers (like network and storage drivers) have existed in FreeBSD 9.x and 10.x for years, but there are still some performance and stability issues and bugs. Compared with Windows and Linux VMs, the current BIS lacks some useful features, e.g., live virtual machine backup, TRIM/Unmap, the support for UEFI VMs (boot from UEFI), etc.

    During the past quarter, we made a great progress on the performance tuning for Hyper-V network driver. We also refactored and cleaned up the VMBus driver, and fixed some important bugs. All the work makes FreeBSD VMs run even better on Hyper-V and the Hyper-V based cloud platform Azure!

    Our work during 2016Q1 is documented below:

    Optimizing the performance of Hyper-V network driver:

    • We added LRO (Large Receive Offloading) support to the driver and properly handle ACK packets. This effectively reduces the CPU cycles used in the TCP/IP stack and dramatically boosts network performance!
    • We enabled vRSS (virtual Receive Side Scaling) support for the driver. This greatly improved the network performance for SMP virtual machines.
    • We used a separate Tx kernel thread to relieve the Rx thread of transmitting packets (the Rx thread tried to transmit packets after receiving ACKs), so the Rx thread can receive packets and send ACKs faster.
    • Now we can reach a VM-to-VM throughput of 9.1Gbps on a host with a 10Gbps physical NIC, and over 20Gbps on a host with a 40Gbps NIC, all the while with plenty of CPU cycles left for applications.
    • We also enabled IP header checksum offloading, and Rx checksum offloading for UDP.
    • Further performance tuning is working in progress.

    Refactoring and cleaning up the VMBus driver code:

    • Instead of using swi threads directly, we now use per-CPU taskqueue_create_fast() threads for event and message handling, making the code more conventional for FreeBSD.
    • We did a lot of cleanup to the hv_utils code (HeartBeat, TimeSync and Shutdown) and we are further cleaning up the KVP code.
    • We used a new message/interrupt slot for the Hyper-V timer, so the handling of timer and non-timer messages can be distinguished, fixing a potential issue.
    • Instead of finding an available IDT vector by hacking, we are changing to use the normal method, lapic_ipi_alloc().
    • We are modularizing the Hyper-V modules:
      1. they will be loaded in the loader;
      2. we are going to enhance devd(8) to improve the hot plug case.

    Bug Fixing:

    • Fixed the "spurious multiple disks" issue (PR 206630 — FreeBSD 10.2 on Windows 10 and 2016 server may not boot due to multiple invalid disks) in the Hyper-V storage driver and now FreeBSD VMs can reliably boot on Win10 and 2016 hosts.
    • Fixed the OACTIVE issue (PR 207297 — [Hyper-V] FreeBSD 10.2 on hyperv lost network under heavy load for OACTIVE).
    • Fixed a TSC calibration issue (PR 208238 — [Hyper-V] TSC frequency is not correctly detected: "calcru: runtime went backwards") and we will not see the "runtime went backwards" messages any more!
    • Fixed the "very slow terminal" issue of 11-CURRENT by enabling text mode when we are running on hypervisors.
    • Fixed the "unknown dhcp option value 0xf5" issue in dhclient(8) by asking dhclient(8) to ignore the option, and FreeBSD VMs on Azure can now reliably get IP addresses.
    • Found a workaround for PR 20824 ([Hyper-V] VM network may not work over virtual switch based on wireless NIC): add "" in /etc/sysctl.conf.

    We plan to add support for live virtual machine backup, TRIM/Unmap, and UEFI VMs (Hyper-V Generation-2 VMs).

    We published errata (FreeBSD-EN-16:04.hyperv, FreeBSD-EN-16:05.hv_netvsc) with the Release Engineering team, so 10.1 and 10.2 users can easily get the fixes for KVP and TCP checksums by upgrading the system.

    We published BIS test cases for Hyper-V on github: and we are going to publish the test cases for Azure soon.

    MMC Stack Under CAM Framework

    Project Information URL:
    Source Code URL:
    Patch for Review URL:

    Contact: Ilya Bakulin <>

    The goal of this project is to reimplement the existing MMC/SD stack using the CAM framework. This will permit utilizing the well-tested CAM locking model and debugging features. It will also be possible to process interrupts generated by the inserted card, which is a prerequisite for implementing the SDIO interface. SDIO support is necessary for communicating with the WiFi/BT modules found on many development boards, like Wan Raspberry Pi 3.

    Another feature that the new stack will have is support for sending SD commands from userland applications using cam(3). This will allow for building device drivers in userland and make debugging much easier.

    The first version of the code was uploaded to Phabricator for review. The new stack is able to attach to the SD card and bring it to an operational state so it is possible to read and write to the card.

    Support for the imx_sdhci SD Host Controller (used on iMX-based boards, for example Wandboard) was added in 2016Q1, along with ti_sdhci, which is used on the BeagleBone Black. Modifying other SDHCI-compliant drivers should not be difficult.

    Open tasks:

    1. Modify the SDHCI driver on at least one x86 platform. This will make development and collaboration easier.

    2. Begin implementing SDIO-specific bits.

    NFS Server

    Contact: Rick Macklem <>

    A new -manage-gids option was added to the nfsuserd daemon. This option tells the NFS server to use the list of groups for a uid on the server and not the list of groups in the NFS RPC request. Use of this option avoids the 16 group limit for NFS RPCs using AUTH_SYS (the default).

    Work is ongoing with respect to development of pNFS support for the NFS server using GlusterFS as a back end. This will be a long-term project with the eventual goal of allowing the NFS server to scale beyond a single server system. Hopefully it will be available for testing in late Spring 2016. pNFS allows an NFSv4.1 client to do reads/writes directly to a data server and not the NFS server.

    Open tasks:

    1. The pNFS server will be in need of testing during development or it will never progress to a near-production status. I hope to have code available in FreeBSD's Subversion project branch for testing in late spring 2016.

    Static Analysis of the FreeBSD Kernel with PVS Studio

    PVS-Studio Delved into the FreeBSD Kernel URL:
    PVS Static Analysis Phabricator Review URL:

    Contact: Warren Block <>

    In February, Program Verification Systems used their PVS-Studio tool to run a static analysis of the FreeBSD kernel. A Phabricator review was created to allow developers to share comments on the results. A number of bugs ranging from trivial typos to redundant code to important logic errors were found and fixed. Some results were false positives. Several of these were addressed by changing code that misled the static analyzer and could also mislead a human reader.

    The cooperation that Program Verification Systems offers to open-source projects like FreeBSD benefits everyone. We thank them for sharing this analysis and their insights with us.


    AmigaOne X5000 Support


    Contact: Justin Hibbits <>

    This project is a continuation of the Book-E QorIQ support enhancements by Semihalf dating back to 2012.

    The AmigaOne X5000 series of AmigaOS-compatible systems uses the Freescale QorIQ series of SoCs for a desktop-class form factor. The work here entails adding support for the e5500 core itself, in addition to support for the SoC peripherals.

    Currently, most of the code to enable basic support is checked in: dTSEC (ethernet), core support (e500mc, e5500). As part of this, rman, the kernel resource manager, was enhanced to use uintmax_t for resources. This allows devices to be physically above the 4GB boundary on 32-bit systems. With a statically compiled device tree, it boots to multiuser mode with nfsroot, and can be used as normal (serial and SSH logins once configured).

    This project was sponsored by Alex Perez (Inertial Computing).

    Open tasks:

    1. eSDHC driver: Work has been started on this, hijacking the imx_sdhc.c from Ian Lepore, but there are still bugs: missing DMA from the iMX driver, and odd timeouts after the system starts up.

    2. SATA support: There is a WIP driver for the SATA controller, but it is currently very slow, about 11MB/s on a SATA 2 link. It currently relies on a 10ms delay on every SATA transaction for it to be even somewhat stable. Without this delay, the disk scan never works and I have not yet figured out why.

    3. Local console (VGA) support: It currently boots with a serial console. vgapci0 is seen if there is a PCIe graphics card, but vt(4) does not attach to it yet.

    4. 64-bit support: The CPU on the board is a P5020, a 64-bit e5500 dual-core SoC. Currently, booke support in FreeBSD is 32-bit only.

    5. SMP: SMP support on Book-E hardware is currently broken.

    6. U-boot support: Currently this uses a compiled-in device tree, but it would be preferable to use the device tree provided by u-boot, or at least the Linux-compatible device tree.

    7. More work is needed on the DPAA front (Datapath Acceleration Architecture) to improve the Ethernet driver and utilize the SEC engine for crypto, random(4), and IPSec.

    FreeBSD on Cavium ThunderX (arm64)

    Contact: Dominik Ermel <>
    Contact: Wojciech Macek <>
    Contact: Zbigniew Bodek <>

    Since the last report, FreeBSD support for ThunderX has been significantly improved and stabilized. Semihalf contributions include the following items:

    • Support for the newest ThunderX chip revisions (Pass 2.0) and current Cavium firmware. Backward compatibility is maintained.
    • Moved to using pci_host_generic.c as a main driver for the internal PCIe bridge. This involved a significant rework of PCIe code to support both generic and ThunderX based platforms.
    • Serious networking performance boost and bug fixes:
      • Fixed race condition on Rx path causing a very rare "use after free" issue
      • Hardware L3 and L4 checksums support
      • Hardware assisted TCP Segmentation Offloading (TSO)
      • Support for software Large Receive Offload (LRO)
      • Various improvements to Tx and Rx paths and configuration

    The driver supports all available Ethernet connections (1, 10, 40 Gbps) and the system can saturate a 10 Gbps link (on Tx) using 4 CPU cores.

    • Significantly improved overall I/O performance:
      • Complete rework of copyin/copyout and bzero functionalities
    • Other improvements:
      • Support for interrupt to CPU binding (including GICv3/ITS backends)

    This work is integrated to FreeBSD HEAD on an on-going basis.

    This project was sponsored by Cavium, and Semihalf.

    Open tasks:

    1. Add support for multi-Queue Set operation in VNIC.

    powerpcspe Target

    Source Tree URL:

    Contact: Justin Hibbits <>

    This project aims to enable the use of the Signal Processing Engine found in the NXP/Freescale e500v2 SoC. The SPE uses opcodes overlapping with those of Altivec, so they are mutually exclusive. Additionally, the e500v2 does not have a traditional FPU, and instead uses the SPE for all floating point operations (or emulation, as is currently done). Combined with the fact that the SPE ABI is incompatible with the traditional ABI, a new MACHINE_ARCH has been created to address these incompatibilities.

    A project branch has been created for the work. A powerpcspe kernel boots on the RouterBoard RB800, and the base utilities run properly.

    Open tasks:

    1. Potentially optimizing setjmp/longjmp to not use SPE unless it has already been enabled. This would save the kernel switch for processes that do not otherwise use the SPE. This is a low priority task which may not be completed.

    Userland Programs

    ELF Tool Chain Tools

    ELF Tool Chain Web Site URL:

    Contact: Ed Maste <>

    The ELF Tool Chain project provides BSD-licensed implementations of compilation tools and libraries for building and analyzing ELF objects. The project began as part of FreeBSD but later became an independent project to encourage wider participation from others in the open-source developer community.

    The ELF Tool Chain project released version 0.7.1 in February. We have been tracking snapshots of the upstream repository in FreeBSD. Having an official release brings the benefit of broader testing and visibility within other open source projects, even if we do not require it in order to update FreeBSD.

    In the first quarter of 2016, the ELF Tool Chain tools were updated to a snapshot of upstream Subversion revision 3400, which is close to the 0.7.1 release. Additional bug fixes were committed to FreeBSD and subsequently merged into the upstream repository.

    ELF Tool Chain's elfcopy(1) is now installed as objcopy(1) by default, as it is a viable replacement for the base system and ports tree.

    Significant improvements were made to the elfcopy(1), readelf(1), and elfdump(1) tools, including better MIPS, RISC-V, and AArch64 support.

    This project was sponsored by The FreeBSD Foundation.

    Open tasks:

    1. Fix issues found by fuzzing inputs to the tools.

    2. Add automatic support for separate debug files.

    3. Investigate replacement objdump, ld and as implementations.

    Native PCI-express HotPlug

    Native PCI-express HotPlug Support URL:

    Contact: John Baldwin <>

    A new implementation of support for native PCI-express hotplug is present at the URL above. Much of the new code lives in the PCI-PCI bridge driver to handle hotplug events and manage the PCI-express slot registers. Additional changes in the branch include adding new rescan and delete commands to devctl(8), as well as support for rescanning PCI busses.

    The current implementation has been tested on systems with ExpressCard slots but could use additional testing, especially on systems with other PCI-express HotPlug features such as mechanical latches, attention buttons, indicators, and so on.

    Open tasks:

    1. Split the branch into separate logical changes as commit candidates.

    2. Additional testing.

    Updates to GDB

    Contact: John Baldwin <>

    The new thread target that directly uses ptrace(2) was committed upstream and included in GDB 7.11. The port was also updated to GDB 7.11.

    Open tasks:

    1. Figure out why the powerpc kgdb targets are not able to unwind the stack past the initial frame.

    2. Add support for more platforms (arm, mips, aarch64) to upstream gdb for both userland and kgdb.

    3. Add support for debugging powerpc vector registers.

    4. Add support for catching system calls.

    5. Add support for $_siginfo.

    6. Add support for ELF auxv data via info auxv.

    7. Implement info os commands.

    8. Implement gdbserver for FreeBSD.

    Using lld, the LLVM Linker, to Link FreeBSD

    FreeBSD lld Wiki Page URL:
    Status Report on Linking FreeBSD/amd64 with lld URL:

    Contact: Rafael Espíndola <>
    Contact: Davide Italiano <>
    Contact: Ed Maste <>

    lld is the linker in the LLVM family of projects. It is intended to be a high-performance linker and supports the ELF, COFF and Mach-O object formats. Where possible, lld maintains command-line and functional compatibility with existing linkers (GNU BFD ld and gold), but lld's authors are not constrained by strict compatibility where it would hamper performance or desired functionality.

    The upstream lld project made significant progress in adding new functionality to lld's ELF support over the first quarter of 2016. The lld ELF linker is capable of self-hosting on FreeBSD/amd64 and is capable of linking many test applications.

    Highlights of upstream development over the quarter include:

    • lld gained Link Time Optimization (LTO) support and is able to link Clang with LTO
    • The relocation code has been overhauled for better maintainability
    • Improvements to linker script support, including better diagnostics
    • Many bug fixes in x86_64, AArch64, and MIPS support

    lld currently lacks comprehensive linker script expression evaluation support, and therefore cannot yet be used to link the FreeBSD kernel. It also lacks versioned symbol support, and does not implement some options used in the FreeBSD boot loader components.

    Ed has been running experimental world builds of FreeBSD/amd64 with lld installed in place of ld.bfd as the linker. With workarounds for the current gaps in functionality (using the WITHOUT_SYMVER option to disable symbol versioning use, and linking the loader components with GNU ld), lld is now able to link a working FreeBSD userland.

    This project was sponsored in part by The FreeBSD Foundation.

    Open tasks:

    1. Enable the lld option by default in the llvm-devel (and later llvm) ports for testing.

    2. Develop symbol version support and linker script expression improvements in the upstream lld project.

    3. Add or improve support for the remaining FreeBSD architectures.

    4. Import a newer lld snapshot into the vendor area, add build infrastructure and connect it to the world build, installed as ld.lld.

    5. Request a ports exp-run with /usr/bin/ld a symlink to ld.lld.

    6. Extensive testing.


    GitLab Port

    Contact: Torsten Zühlsdorff <>

    After nearly a year of work on this project, GitLab 8.5.5 was committed into the ports tree. A big thanks to the enormous number of people involved! Since GitLab is a fast-moving project, there is also ongoing work to stay in sync with upstream. Have fun!

    Contact: FreeBSD GNOME Team <>

    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.

    This quarter, GNOME 3.18 and MATE 1.12 were committed to the ports tree.

    The and frameworks were replaced by the simpler Uses/ and Uses/ style.

    Open tasks:

    1. Tracking MATE 1.13, the development version that will become MATE 1.14.

    2. Work started on porting GNOME 3.20.

    3. We have Cinnamon 2.8 in our development tree, but we do not have the time to properly test and fix the issues before this Cinnamon can be committed to ports. Interested in helping or taking maintainership of Cinnamon? Please let us know.

    Development Repository for Integrating KDE Frameworks 5 and Plasma 5 URL:

    Contact: KDE on FreeBSD team <>

    The KDE on FreeBSD team focuses on packaging and making sure that the experience of KDE and Qt on FreeBSD is as good as possible.

    While the list of updates is shorter than that for the previous quarter, the team remained busy and work on KDE Frameworks 5 and Plasma 5 continues.

    Tobias Berner, who has been driving our KDE Frameworks 5 and Plasma 5 efforts from the beginning, received a KDE commit bit, and has been putting it to good use by upstreaming FreeBSD across several KDE repositories. Another team highlight in the beginning of this year is the (re)addition of another committer to our experimental repository: Adriaan de Groot, a longtime KDE contributor who also used to work on KDE and FreeBSD almost a decade ago when our team was first formed. Welcome back, Ade!

    The following big updates were landed in the ports tree this quarter. In many cases, we have also contributed patches to the upstream projects.

    • CMake 3.4.2 and 3.5.0
    • Calligra 2.9.11, the latest release of the integrated work applications suite. We have managed to keep in sync with the upstream releases since 2.9.10.
    • KDE Telepathy was updated to 0.9.0 and Telepathy-Qt4 was updated to, the latest upstream releases.
    • The Qt 5 ports were finally updated to 5.5.1, which were the latest stable version at the time.
    • The first commit preparing the groundwork for KDE Frameworks 5 and Plasma 5 was landed to the ports tree.

    Work on Qt 5.6.0 is under way in our experimental repositories. At the time of this writing, it also contains KDE Frameworks 5.20.0, Plasma 5.6.1, and KDE Applications 16.03.80.

    Users interested in testing those ports are encouraged to follow the instructions in our website and report their results to our mailing list. Qt5 5.6.0 is in our qt-5.6 branch, and Plasma 5 and the rest is in the plasma5 branch.

    Open tasks:

    1. Land the KDE Frameworks 5 and Plasma 5 ports to the tree.

    2. Commit the DigiKam 4.14.0 update currently being worked on in our experimental repository.

    Obsoleting Rails 3

    Contact: Torsten Zühlsdorff <>

    Ruby on Rails is the base for most of the rubygems in the Ports Collection. Currently, versions 3.2 and 4.2 coexist, but since Rails 3.2 is running out of support, the time has come to switch.

    There is an ongoing progress to remove Rails 3.2 from the ports tree. While many gems already work with the new version, there are some exceptions. For example, www/redmine needs a big update (which is currently being tested) because it depends on gems that depends on Rails 3.2.

    If you want to help with porting or testing, feel free to contact me or the mailinglist

    Ports Collection


    Contact: Frederic Culot <>
    Contact: FreeBSD Ports Management Team <>

    As of the end of Q1, the ports tree holds a bit more than 25,000 ports, and the PR count is below 1,900. The activity on the ports tree remains steady, with almost 7,000 commits performed by around 120 active committers.

    On the problem reports front, the encouraging trend observed during the previous quarter is confirmed, with again a significant increase in the number of PRs fixed during Q1. Indeed, almost 2,400 reports were fixed, which allows us to go below the threshold value of 2,000 open PRs.

    In Q1, three commit bits were taken in for safekeeping, following an inactivity period of more than 18 months (milki, brian), or on committer's request (mmoll). We had one returning committer (fluffy) who had his commit bit reinstated. Two new developers were granted a ports commit bit (Olivier Cochard-Labbe and Christoph Moench-Tegeder).

    On the management side, we had the pleasure to welcome miwi back to the portmgr team.

    On the QA side, 39 exp-runs were performed to validate sensitive updates or cleanups. The most noticeable change might be the removal of the now unneeded ${PORTSDIR} when specifying dependencies in Makefiles (see the /usr/ports/CHANGES entry dated 20160402). Amongst other noticeable changes are the update to ruby 2.3, ruby-gems to 2.5.1, CMake to 3.5.0, clang to 3.8.0-r258968, Qt5 to 5.5.1, Gnome to 3.18, boost to 1.60.0, the update of libc++ in base to 3.8.0 release, and the enabling of LLVM libunwind by default on x86. The CentOS ports were also updated. Some infrastructure changes included the switch from and to the simpler Uses/ and Uses/ Some work was also done to improve poudriere builds by reducing dependency calculation and general overheads.

    Open tasks:

    1. We would like to remind everyone that the ports tree is built and run by volunteers, and any help is greatly appreciated. A great amount of effort was spent on the ports front in Q1, which allowed us to decrease the number of pending problem reports significantly, as well as on the ports infrastructure. Many thanks to all who contributed!

    Federico Caminiti created an entirely new Spanish translation of the 31,000-word FAQ with editorial help from Carlos J Puga Medina.

    This landmark accomplishment marks the first use of the new PO translation system to translate an entire book!

    Ruey-Cherng Yu has begun an ambitious Traditional Chinese (zh_TW) translation of the 64,000-word Porter's Handbook. About half of the strings in the book have been translated so far.

    Open tasks:

    1. Help add and improve translations of FreeBSD documents into Spanish: start of freebsd-translators thread.

    2. Help add and improve translations of FreeBSD documents into Chinese or other languages.

    Contact: Johann Kois <>

    The FreeBSD German Documentation Project translates FreeBSD's documentation (handbook, articles, website, etc.) into the German language.

    Due to the tireless effort of Björn Heidotting, we made huge improvements in catching up with the translation of the German handbook. Benedict helped with reviewing the changes using FreeBSD's review system Phabricator, which helped a lot. We now have the following handbook chapters in sync with the latest version in the English tree:

    • filesystems
    • kernelconfig
    • ports
    • x11

    We try to keep up the good work, while also looking at new ways to translate like the PO/gettext-based system. We are always looking for volunteers who are interested in translating small sections or even entire documents. The process is relatively easy and contributors do not have to know much to get started. The members of the FreeBSD German Documentation Team are also willing to mentor people who are interested in helping out.

    Open tasks:

    1. Translate more documents.


    FreeBSD Build

    Contact: Bryan Drewery <>

    Build improvements for buildworld on FreeBSD head continue. Some highlights include:

    • WITH_FAST_DEPEND was made the default in r296668, and later made the only option in r297434. The new depend code avoids a make depend tree walk and generates .depend files during the build as a side-effect of compilation. This is done by using the -MF flags of the compiler. This speeds up the build by 15-35%.
    • PR 196193: WITHOUT_CROSS_COMPILER was fixed to properly use --sysroot which allows the option to work in more cases. It is still unsafe when major compiler upgrades occur. Further work is planned to improve that still.
    • WITHOUT_TOOLCHAIN now properly builds.

    This project was sponsored by EMC / Isilon Storage Division.

    Open tasks:

    1. Opportunistically skipping the bootstrap compiler phase of buildworld.

    2. Skipping the make obj tree walk.

    3. Enabling WITH_META_MODE in buildworld to provide a reliable incremental build using filemon(4) and bmake's .MAKE.MODE=meta. This should not be confused with WITH_DIRDEPS_BUILD which previously was named WITH_META_MODE and is a drastically different build system presented at BSDCan 2014 by Simon Gerraty.

    Qt 5.6 on Raspberry Pi

    Qt 5.6 on FreeBSD/Pi URL:

    Contact: Oleksandr Tymoshenko <>

    Qt 5.6 is a great framework for building embedded GUI applications, so when Qt 5.6 was released it was natural to bring it up on the Raspberry Pi. The current Qt support in ports is very Xorg-centric, so as a proof of concept I created an experimental qt56-base and qt56-multimedia.

    qt56-base can be configured for a generic ARM device with the scfb video driver, and specifically for Raspberry Pi in which case it supports EGLFS mode with hardware OpenGL acceleration.

    Open tasks:

    1. Check how embedded use cases can be fit into the current or whether a new port should be introduced.

    The FreeBSD Foundation is a 501(c)(3) non-profit organization dedicated to supporting and promoting the FreeBSD Project and community worldwide. Funding comes from individual and corporate donations and is used to fund and manage development projects, conferences and developer summits, and provide travel grants to FreeBSD developers. The Foundation purchases hardware to improve and maintain FreeBSD infrastructure and publishes FreeBSD white papers and marketing material to promote, educate, and advocate for the FreeBSD Project. The Foundation also represents the FreeBSD Project in executing contracts, license agreements, and other legal arrangements that require a recognized legal entity.

    Here are some highlights of what we did to help FreeBSD last quarter:

    Fundraising Efforts

    We raised $204,000 last quarter from individual and corporate donors. Thank you to everyone who made a donation this year! The list of donors is available.

    OS Improvements

    The Foundation improves FreeBSD by funding software development projects approved through our proposal submission process, and our three software developer staff members. Two Foundation-funded projects were started last quarter, the first to improve the stability of the vnet network stack virtualization infrastructure, and the second for phase two of the FreeBSD/arm64 port project.

    Foundation staff members were responsible for many changes over the quarter. Some notable items include process-shared pthread locks, address mapping randomization, disk I/O bandwidth limits, porting libunwind to FreeBSD/arm, bug fixes in the autofs automount daemon, an updated version of the ELF Tool Chain, investigation of the lld linker, improved x86 hardware support, and VM subsystem stability improvements. Several of these projects are described elsewhere in this quarterly report.

    Release Engineering

    Foundation employee and release engineer Glen Barber worked on packaging the base system with pkg(8), separating debug files from the default base system so they can be selected or deselected during an install, supporting preparations, testing for the on-time release of FreeBSD 10.3, and producing 11-CURRENT and 10-STABLE snapshot builds.

    FreeBSD Advocacy

    Anne Dickison, our Marketing Director, focused on creating and updating marketing material to promote and teach people about FreeBSD. This material is available for FreeBSD advocates to hand out at conferences and events to promote FreeBSD. She also worked on promoting FreeBSD work being done over social media, blog posts, and articles.

    Last quarter, we continued our Faces of FreeBSD series by publishing stories about Scott Long and Sean Bruno. This is an opportunity to put a face to a name in the FreeBSD community and get to know more about the people who contribute to FreeBSD.

    Work began on updating the FreeBSD 10.X brochure to include the new 10.3 features.

    We love getting stories from companies who are successfully using FreeBSD. Testimonials were received last quarter from Chelsio and Acceleration Systems.

    ZFS was making some headlines, so we wrote a blog entry on the longstanding relationship between FreeBSD and ZFS.

    We helped promote the FreeBSD RISC-V work being done.

    Assistance was provided to Mellanox for their press release highlighting their work with NetFlix.

    Conferences and Events

    The FreeBSD Foundation sponsors many conferences, events, and summits around the globe. These events can be BSD-related, open source, or technology events geared towards underrepresented groups. We provide financial support to the major BSD conferences like BSDCan, AsiaBSDCon, and EuroBSDCon, and give financial and/or other support for smaller events like BSDDays, FreeBSD Summits, and FreeBSD workshops, camps, and hackathons. For open source conferences, we will attend when we can get a free non-profit booth.

    The year kicked off with sending Ed Maste, Benedict Reuschling, and George Neville-Neil to promote and give talks on FreeBSD at FOSDEM, the largest open source conference in Europe. Ed, our Project Development Director, had a chance to talk to developers from other projects based on FreeBSD, and various people about reproducible builds in FreeBSD.

    Dru Lavigne and Deb Goodkin promoted FreeBSD at SCALE in Pasadena, California. Dru gave a presentation called "Doc Like an Egyptian." We were a Gold Sponsor for AsiaBSDCon in Tokyo, and five Foundation members attended. Kirk McKusick taught a two-day FreeBSD Kernel tutorial and gave a talk on the history of the BSD filesystem. Dru Lavigne and Benedict Reuschling gave a documentation tutorial. Board members Hiroki Sato and George Neville-Neil helped organize the conference. interviewed Benedict at AsiaBSDCon about his role as a new Foundation board member and the Foundation's work.

    We planned and organized our first-ever FreeBSD Storage Summit in association with the USENIX FAST Conference. Led by our President and Founder, Justin Gibbs, we had over 50 attendees participating and working together on technically focused topics. Benedict was busy promoting FreeBSD in Europe, where he also attended Linuxtage in Chemnitz, Germany to give a talk on FreeBSD (in German): FreeBSD — The Power to Serve a Community.

    The Foundation committed to being a Gold Sponsor for BSDCan and the upcoming Hackathon/DevSummit in Essen, Germany in April.

    Legal/FreeBSD IP

    The Foundation owns the FreeBSD trademarks, and it is our responsibility to protect them. We continued to review requests for permission to use the trademarks.

    FreeBSD Community Engagement

    Code of Conduct — Anne Dickison, our Marketing Director, has been overseeing the efforts to rewrite the Project's Code of Conduct to help make this a safe, inclusive, and welcoming community.

    We have been reaching out to other open source communities to get help with our efforts in making this a diverse community and help us achieve our goals mentioned above of making the FreeBSD community safe, inclusive, and welcoming.

    Continuing with our diversity efforts, we have been connecting with women in technology groups to work on how we can recruit more women to FreeBSD and offer Intro to FreeBSD workshops.

    Meetings were held with a number of commercial vendors to help facilitate collaboration with the Project. This included presenting how the Project is organized, and how companies can get help, contribute back to the Project, promote their use of FreeBSD, and for us to get their feedback on the work we are doing to help with our fundraising efforts.

    The new Foundation website and logo was launched, signaling the ongoing evolution of the Foundation identity and ability to better serve the FreeBSD Project and community. Find our more about our new look.
