pkgsrcCon is the annual technical conference for people working on pkgsrc, a framework for building over 17,000 open source software packages. pkgsrc is the native package manager on NetBSD, SmartOS and Minix, and is portable across many different operating systems including Linux and Mac OS X.

The last year's pkgsrcCon 2016 event took place in Kraków, Poland.

Slides are available on the event site.

We would like to thank the organizers, sponsors and promotion from the Jagiellonian University, The NetBSD Foundation, Programista Magazyn, OS World, and Subcarpathian BSD User Group.

Posted Saturday afternoon, July 1st, 2017 Tags:
Over the last 30 days I was focusing on getting the environment to enable LLVM sanitizers and the Clang compiler on NetBSD. Meanwhile I pushed forward generic parts that were needing enhancements around pkgsrc and LLVM in general to ease the future LLDB work.

dogfood

When I have realized that in order to work on the LLVM sanitizers I need to use Clang as the compiler. A part of the compiler-rt (lowlevel LLVM compiler runtime library) has code specifically incompatible with GCC. It was mainly related to intrinsic instructions for atomic functions. I tried to research how much work is needed to port it to GCC. It happened to be non-trivial and I filed a bug on the LLVM bugzilla.

These circumstances made me to switch to Clang as the pkgsrc toolchain. I was using it to test the compilation of small bulks of packages and record build and compiler problems. To save time, I used ccache as my cache for builds.

My options in mk.conf(5):

PKGSRC_COMPILER=        ccache clang
CCACHE_BASE=            /usr/local
CCACHE_DIR=             /public/ccache_tmp
CCACHE_LOGFILE=         /tmp/ccache.txt
PKG_CC=                 clang
PKG_CXX=                clang++
CLANGBASE=              /usr/local
HAVE_LLVM=              yes

It's worth noting that ccache with pkgsrc won't check $HOME/.ccache for configuration, it must be placed in $CCACHE_DIR/ccache.conf.

The documented problems can be summarized as:

  • Broken ccache in pkgsrc for C++11 packages.
    The pkgsrc framework started supporting C++ languages in the USE_LANGUAGES definition. Packages with newly added USE_LANGUAGES values (such as c++11) were not compiled with ccache because ccache.mk was not yet aware of such values. This broke support of these packages to set these values to be built with ccache. I've corrected it and introduced a new option CCACHE_LOGFILE to more easily track execution of ccache and detect errors.
  • Broken ccache in pkgsrc for a custom toolchain.
    ccache tries finding a real-compiler looking for it in $PATH. When I have built clang within pkgsrc to work on it (installed into /usr/pkg), and I had my main toolchain in /usr/local it was picking the one from /usr/pkg for new builds and it resulted in cache-misses for new builds. I have installed a fix for it to pass ccache specific PATH to always find the appropriate compiler.
  • Header <execinfo.h> cannot be included on Clang 5.0.0svn.
    For some reason compilers tend to install their own headers that overshadow the system headers. This resulted in build failures in programs including plain <execinfo.h> header (for the backtrace(3) function). This system header used to include <stddef.h> that included our <sys/cdefs.h>... with shadowed <stddef.h> by Clang 5.0.0svn (from $PREFIX/lib/clang/5.0.0/include/stddef.h). Christos Zoulas fixed it by making <execinfo.h> standalone and independent from standard libc headers.
  • __float128 and GNU libstdc++.
    Our basesystem GNU libstdc++ enables __float128 on i386, amd64 and i64 ports. As of now the LLVM equivalent library contains partial support for this type. This results in a problem that affects 3rd party programs in the setup of Clang + libstdc++ detect __float128 support and break because the compiler does not define appropriate global define __FLOAT128__. This issue is still open for discussion on how to solve it for NetBSD.
  • gforth optimization problems.
    Upstream gforth developers ported this FORTH compiler to Clang, and triggered an optimization issue with attempting to needlessly solve a complex internal problem. This results with compilation times of several minutes on a modern CPUs instead of getting the results immediately. The problem has been already reported on the LLVM bugzilla and I have filed a report that it is still valid.
  • bochs can be built with clang.
    A while ago, bochs was buildable only by the GCC compilers and the Clang toolchain was blacklisted. I have verified that this is no longer the case and unmasked the package for compilers other than GCC.

LLVM and Clang testsuites

I have prepared Clang and LLVM testsuites to execute on NetBSD. Correctness of both projects is crucial for LLDB and the LLVM sanitizers to work because their issues resound problems inside programs that depend on them. Originally I have corrected the tests with local patches to build with GCC, and switched later to Clang. I have restructured the packages in pkgsrc-wip in order to execute the test-suite. I have fixed 20 test failures in LLVM implementing AllocateRWX and ReleaseRWX for the NetBSD flavor of PaX MPROTECT. There are still over 200 failures to solve!

It's worth noting that the googletest library (used in a modified version in LLVM and in a regular one in Clang) finally accepted the NetBSD patches.

LLVM asan and ubsan

I expect to get four LLVM sanitizers working in order to move on to LLDB: asan (address sanitizer), ubsan (undefined behavior sanitizer), tsan (thread sanitizer), msan (memory sanitizer). The other ones like dfsan (data-flow sanitizer) or lsan (leak sanitizer) are currently to be skipped. In general, sanitizers are part of the LLDB functionality that I want to get aboard on NetBSD, as there are plugins to integrate them within the debugger. In the current state I require them to debug bugs inside LLDB/NetBSD.

The original work on sanitizers in GCC (with libsanitizer) has been done by Christos Zoulas. GCC libsanitizer is a close sibling of compiler-rt/lib from the LLVM project. I picked up his work and integrated it into compiler-rt and developed the rest (code differences, fixing bugs, Clang/LLVM specific parts in llvm/ and clang/) and I managed to get asan and ubsan to work.

Users should pickup pkgsrc-wip in revision 3e7c52b97b4d6cb8ea69a081409ac818c812c34a and install wip/{llvm,clang,compiler-rt}-netbsd. Clang will be ready for usage:

/usr/pkg/bin/clang -fsanitize=undefined test.c
and
/usr/pkg/bin/clang -fsanitize=address test.c

Additional compiler commands that may improve the experience:

-g -O0 -fno-omit-frame-pointer -pie -fPIE

These sanitizers are not production ready and are active under development.

Plan for the next milestone

Roadmap for the next month:

  • Finish and send upstream LLVM asan and ubsan support.
  • Correct more problems triggered by LLVM and Clang test-suites.
  • Resume msan and tsan porting.

This years pkgsrcCon returned to London once again. It was last held in London back in 2014. The 2014 con was the first pkgsrcCon I attended, I had been working on Darwin/PowerPC fixes for some months and presented on the progress I'd made with a 12" G4 PowerBook. I took away a G4 Mac Mini that day to help spare the PowerBook for use and dedicate a machine for build and testing. The offer of PowerPC hardware donations was repeated at this years con, thanks to jperkin@ who showed up with a backpack full of Mac Minis (more on that later).

Since 2014 we have held cons in Berlin (2015) & Krakow (2016). In Krakow we had talks about a wide range of projects over 2 days, from Haiku Ports to Common Lisp to midipix (building native PE binaries for Windows) and back to the BSDs. I was very pleased to continue the theme of a diverse program this year.

Aside from pkgsrc and NetBSD, we had talks about FreeBSD, OpenBSD, Slackware Linux, and Plan 9.
Things began with a pub gathering on the Friday for the pre-con social, we hung out and chatted till almost midnight on a wide range of topics, such as supporting a system using NFS on MS-DOS, the origins of pdksh, corporate IT, culture and many other topics.

On parting I was asked about the starting time on Saturday as there was some conflicting information. I learnt that the registration email had stated a later start than I had scheduled for & advertised on the website, by 30 minutes.
Lesson learnt: register for your own event!
Not a problem, I still needed to setup a webpage for the live video stream, I could do both when I got back. With some trimming here and there I had a new schedule, I posted that to the pkgsrcCon website and moved to trying to setup a basic web page which contained a snippet of javascript to play a live video stream from Scale Engine.
2+ hours later, it was pointed out that the XSS protection headers on pkgsrc.org breaks the functionality. Thanks to jmcneill@ for debugging and providing a working page.

Saturday started off with Giovanni Bechis speaking about pledge in OpenBSD and adding support to various packages in their ports tree, alnsn@ then spoke about installing packages from a repo hosted on the Tor network.

After a quick coffee break we were back to hear Charles Forsyth speak about how Plan 9 and Inferno dealt with portability, building software and the problem which are avoided by the environment there. This was followed by a very energetic rant by David Spencer from the Slackbuilds project on packaging 3rd party software. Slackbuilds is a packaging system for Slackware Linux, which was inspired by FreeBSD ports.

For the first slot after lunch, agc@ gave a talk on the early history of pkgsrc followed by Thomas Merkel on using vagrant to test pkgsrc changes with ease, locally, using vagrant. khorben@ covered his work on adding security to pkgsrc and bsiegert@ covered the benefits of performing our bulk builds in the cloud and the challenges we currently face.
My talk was about some topics and ideas which had inspired me or caught my attention, and how it could maybe apply to my work.The title of the talk was taken from the name of Andrew Weatherall's Saint Etienne remix, possibly referring to two different styles of track (dub & vocal) merged into one or something else. I meant it in terms of applicability of thoughts and ideas. After me, agc@ gave a second talk on the evolution of the Netflix Open Connect appliance which runs FreeBSD and Vsevolod Stakhov wrapped up the day with a talk about the technical implementation details of the successor to pkg_tools in FreeBSD, called pkg, and how it could be of benefit for pkgsrc.

For day 2 we gathered for a hack day at the London Hack Space.
I had burn't some some CD of the most recent macppc builds of NetBSD 8.0_BETA and -current to install and upgrade Mac Minis. I setup the donated G4 minis for everyone in a dual-boot configuration and moved on to taking apart my MacBook Air to inspect the wifi adapter as I wanted to replace it with something which works on FreeBSD. It was not clear from the ifixit teardown photos of cards size, it seemed like a normal mini-PCIe card but it turned out to be far smaller. Thomas had also had the same card in his and we are not alone. Thomas has started putting together a driver for the Broadcom card, the project is still in its early days and lacks support for encrypted networks but hopefully it will appear on review.freebsd.org in the future.
weidi@ worked on fixing SunOS bugs in various packages and later in the night we setup a NetBSD/macppc bulk build environment together on his Mac Mini.
Thomas setup an OpenGrock instance to index the source code of all the software available for packaging in pkgsrc. This helps make the evaluation of changes easier and the scope of impact a little quicker without having to run through a potentially lengthy bulk build with a change in mind to realise the impact.
bsiegert@ cleared his ticket and email backlog for pkgsrc and alnsn@ got NetBSD/evbmips64-eb booting on his EdgeRouter Lite.

On Monday we reconvened at the Hack Space again and worked some more. I started putting together the talks page with the details from Saturday and the the slides which I had received, in preperation for the videos which would come later in the week. By 3pm pkgsrcCon was over. I was pretty exhausted but really pleased to have had a few days of techie fun.

Many thanks to The NetBSD Foundation for purchasing a camera to use for streaming the event and a speedy response all round by the board. The Open Source Specialist Group at BCS, The Chartered Institute for IT and the London Hack Space for hosting us. Scale Engine for providing streaming facility. weidi@ for hosting the recorded videos.
Allan Jude for pointers, Jared McNeill for debugging, NYCBUG and Patrick McEvoy for tips on streaming, the attendees and speakers. This year we had speakers from USA, Italy, Germany and London E2.
Looking forward to pkgsrcCon 2018!

A new SUNXI evbarm kernel has appeared recently in NetBSD -current with support for boards based on the Allwinner H3 system on a chip (SoC). The H3 SoC is a quad-core Cortex-A7 SoC designed primarily for set-top boxes, but has managed to find its way into many single-board computers (SBC). This is one of the first evbarm ports built from the ground up with device tree support, which helps us to use a single kernel config to support many different boards.

To get these boards up and running, first we need to deal with low-level startup code. For the SUNXI kernel this currently lives in sys/arch/evbarm/sunxi/. The purpose of this code is fairly simple; initialize the boot CPU and initialize the MMU so we can jump to the kernel. The initial MMU configuration needs to cover a few things -- early on we need to be able to access the kernel, UART debug console, and the device tree blob (DTB) passed in from U-Boot. We wrap the kernel in a U-Boot header that claims to be a Linux kernel; this is no accident! This tells U-Boot to use the Linux boot protocol when loading the kernel, which ensures that the DTB (loaded by U-Boot) is processed and passed to us in r2.

Once the CPU and MMU are ready, we jump to the generic ARM FDT implementation of initarm in sys/arch/evbarm/fdt/fdt_machdep.c. The first thing this code does is validate and relocate the DTB data. After it has been relocated, we compare the compatible property of the root node in the device tree with the list of ARM platforms compiled into the kernel. The Allwinner sunxi platform code lives in sys/arch/arm/sunxi/sunxi_platform.c. The sunxi platform code provides SoC-specific versions of code needed early at boot. We need to know how to initialize the debug console, spin up application CPUs, reset the board, etc.

Instead of writing H3-specific code for spinning up application CPUs, I took advantage of U-Boot's Power State Coordination Interface implementation. A psci(4) driver was added and the allwinner,sun8i-h3 platform code was modified to use this code to start up all processors.

With a bit of luck, we're now booting and enumerating devices. Apart from a few devices, almost nothing works yet as we are missing a driver for the CCU. The CCU in the Allwinner H3 SoC controls PLLs and most of the clock generation, division, muxing, and gating. Since there are many similarities between Allwinner SoCs, I opted to write generic CCU code and then SoC-specific frontends. The resulting code lives in sys/arch/arm/sunxi/; generic code as sunxi_ccu.c and H3-specific code in sun8i_h3_ccu.c.

Now we have a CCU driver, we can attach a com(4) and have a valid console device.

After this, it's a matter of writing drivers and/or adapting existing code to attach to fdtbus based on the bindings used in the DTB. For cases where we had a compatible driver in the old Allwinner port, I opted to make a copy of the code and FDT-ize it. A few reasons for this -- 1) the old drivers have CCU-specific code with per-SoC ifdefs scattered throughout, 2) I didn't want to break existing kernels, and 3) long term goal is to move the SoCs supported by the old code over to the new code (this process has already started with the Allwinner A31 port).

So what do we get out of this? This is a step towards being able to ship a GENERIC evbarm kernel. I developed the H3 port on two boards, the NanoPi NEO and Orange Pi Plus 2E, but since then users on port-arm@ have been reporting success on many other H3 boards, all from a single kernel config. In addition, I've added support for other Allwinner SoCs (sun8i-a83t, sun6i-a31) to the kernel and have tested booting the same kernel across all 3 SoCs.
