DragonFly 3.6.2 released


Release 3.6.2 of DragonFly has been tagged, and ISO/img files are available.  This includes an updated OpenSSL for Heartbleed problems.  Here’s the changelog.  You can, if you haven’t already, update your existing 3.6 systems the normal way.

HTTPS, OpenSSL, and dragonflybsd.org


All the dragonflybsd.org sites (www, bugs, gitweb, lists, leaf) should be available via https now, thanks to a wildcard certificate from InterNetX.  Also, all the machines have an up-to-date version (1.0.1g) of OpenSSL installed to prevent the Heartbleed issue.

Rescue RAMdisk to test


Francois Tigeot’s rescue ramdisk work is ready for testing.  You can pull it directly from his repo and try it out.  It’s surprising how small the ramdisk can be crunched.

Note: he now has a newer branch than what is in that linked message.

For the next DragonFly release


I wrote up some thoughts for the next release of DragonFly.  There’s some project work in there for anyone interested.  The next release should be near the end of May.

NSS/LDAP and DragonFly


One of the requirements to get NSS/LDAP working on (most) any unixlike system is to have dynamic binaries; meaning they are dependent on various libraries to run.  Since you’re talking about programs for login when you’re talking about NSS/LDAP, that means if the libraries aren’t available, you can’t log in.  DragonFly has static binaries just to avoid that problem.

Francois Tigeot proposed switching to dynamic binaries and building a /rescue directory with static backups, as is the case with I think FreeBSD and NetBSD.  If you follow the thread, it looks like the best path is to use initrd instead.  Initrd stands for INITial Ram Disk, and is the first volume the computer sets up to boot from BIOS.  Since initrd gives the computer enough space to load all the needed modules (like Hammer2…), it works without making the computer dependent on various libraries or having a bloated /rescue directory.

(Someone correct me if I have the details wrong.)  As long as we’re talking about things that would help DragonFly in a larger environment, can someone work on a VM balloon memory driver, too?

GUI images for DragonFly 3.6 sort of


If you noticed the lack of a GUI DVD image for the 3.6 release of DragonFly, I posted a followup note on the users@ list that talks about the steps to get X installed.  It’s not much work, with pkg set up.

Open source classes at RIT


Normally I’d save this for Lazy Reading, but I’m indirectly involved: the Rochester Institute of Technology now has a minor in Open Source and Free Culture.  Here’s the press release.  I taught one of the precursor classes, Humanitarian Free/Open Source Development (essentially open source development methods) last spring.  Steve Jacobs was my advisor years ago and Remy Decausemaker was my (best) student from the HFOSS class.  In any case, the courses are definitely worth it.  (via)

pfi, the automated installer that nobody knows about, now supports installing an authorized_keys file as part of an install.  Credit goes to Alex Hornung for adding the functionality.

DragonFly 3.6.1 released


I’ve tagged version 3.6.1 of DragonFly, and built ISO/img files of it.  They should be available by now on mirrors if you need them, or you can just upgrade as normal.   See the linked tag commit message for what’s changed.

3.8 release goals


Antonio Huete put together a list of goals for the next release on the DragonFly bugtracker.  Some of them are pretty ambitious, some of them are relatively easy, but they are all very useful.

C-state sysctl followup


Probably because of the C-state changes, Sepherosa Ziehau wants people to use a new set of sysctls instead of the hw.cpu_mwait* ones – at least on x86_64.  This won’t affect you if you aren’t already familiar with them, probably.

Time zone changes


Recent updates to tzcode apparently fixed a long-standing time zone bug in DragonFly.  POSIX says the America/New_York timezone is picked as default if nothing else has been selected.  That didn’t happen in DragonFly – until recently.  If your timezone seemed to suddenly jump to U.S. Eastern time, that’s because you never picked before.

DragonFlyBSD.org status page


Antonio Huete set up a DragonFly status page on status.io.

ACPICA update for testing


If you want to test out the latest (20131218) update to ACPICA, Sepherosa Ziehau’s got a patch for you.  This will be good for anyone who wants to use less electricity.  (updated to reflect this doesn’t enable deeper C-states as I thought it did.)

DragonFly on a Chromebook c720


Matthew Dillon acquired one of the Acer c720 Chromebooks recently.  There were changes needed for the boot process, for the keyboard, an update from FreeBSD for the ath(4) wireless (g), smbus, and trackpad… but it works now, and he detailed exactly how to get it running, and even upgrade the drive.

Binutils update to 2.24


John Marino has moved DragonFly from binutils 2.22 to 2.24.  I think this may require a full buildworld when upgrading…  not sure.  Anyway, binutils has a changelog if you are curious.

Minimal installation notes


This post from Konrad Neuwirth asking how to do a minimal installation of DragonFly led to this list of all the ‘knobs’ you can set to make your installation smaller, from John Marino.  (And your buildworld faster, if that’s appealing to you.)  I also pointed at rconfig and PFI, which are criminally underdocumented.

New pkg 1.2 on the way


pkg 1.2 is coming out.  This brings a number of new features, but as John Marino posted, you may want to delete your old pkg.conf to keep the new version from complaining about an old config file.  This upgrade is a step on the way to signed packages, which is a Good Idea.

DragonFly roadmap, post 3.6


John Marino posted a possible ‘roadmap’ for DragonFly, now that we’re past the 3.6 release.  The thread went on for some ways as it was discussed, including my crazy ideas.  Notably, several suggested items have already been tackled – an iwn(4) upgrade has already happened, and an update to bmake, based on John’s vendor branch update instructions.

Hammer2 status


This is a little old, but Matthew Dillon noted the status of his Hammer2 work a little while ago.  Some highlights: he’s intending Hammer2 to be usable on a single host by the time of the next DragonFly release (summer 2014), the Summer of Code project for compression has already been integrated, and he listed different parts of the work that may be interesting for anyone wanting to chip in.

Slightly related: Matt posted some Hammer2 comments on the DragonFly 3.6 release story on Slashdot that may be interesting.  Don’t bother reading the other comments; they’ll make your eyeballs bleed.

DragonFly 3.6 released


The 3.6 release of DragonFly is available now.  I just put up those images last night, so if your favorite mirror doesn’t have it, give it a few hours.

For those updating from 3.4 to 3.6: there’s an ABI change, so you will have to upgrade all your packages.  If you’re using pkgsrc and ready to switch to dports, now’s the time.  If you already switched to dports on your 3.4 system, binary packages for 3.6 have already been built and you can use pkg to upgrade.

Also for upgrades from 3.4: You can pull the 3.6 source normally:

cd /usr/src
git fetch origin
git branch DragonFly_RELEASE_3_6 origin/DragonFly_RELEASE_3_6
git checkout DragonFly_RELEASE_3_6

But there’s a slight change needed for the 3.4 to 3.6 transition: an extra reboot in the build process:

# make buildworld && make buildkernel && make installkernel && make installworld && reboot

# make upgrade

This is all noted in /usr/src/UPDATING and in the release notes, but I’m taking no chances.

Performance tuning


Matthew Dillon did some more performance tuning for DragonFly.  I’ll just pull a paragraph from the commit message, since that will have more impact than anything I say:

Improves fork/exec concurrency on monster of static binaries from 14200/sec to 55000/sec+. For dynamic binaries improve from around 2500/sec to 9000/sec or so (48 cores fork/exec’ing different dynamic binaries). For the same dynamic binary it’s more around 5000/sec or so.

“monster” is a 48-core machine used for testing.

DragonFly developer interview

lpr, still in use


The venerable (from 1979!) program, lpr, has been superseded by CUPS in many installations.  Francois Tigeot suggested removing it, but it’s still directly usable in specific situations and easier to just shift out of the way.  It’s staying, but it’s interesting to see how it still gets used.

Update: Predrag Punosevac has descriptions of the various tools involved.

DragonFly pkgsrc repo is frozen


The pkgsrc repository in git for DragonFly is currently frozen.  This is because many people have switched over to dports, and also because it’s a lot of work to keep it functional.  If you do want to pull newer pkgsrc material, use cvs and grab it from a NetBSD server.

As the message notes, don’t go switching to DragonFly-current right now, cause there’s a lot of new material in there and it may not be quite safe.  (There’s an ABI change that will require all new builds of your ports, for instance.)

Mirrored disks and rconfig


Antonio Huete Jimenez has added a new rconfig script that automatically mirrors the installed disks with ccd(4).  You don’t remember what to do with rconfig(8)?  Automatically (and headlessly) install DragonFly, of course!  There’s already other examples – they’re just shell scripts.

DragonFly and future planning


I put together a list of what I’m thinking could be in the next DragonFly release.  Going by our regular schedule, that’s a bit more than a month off.  Of note: Summer of Code material and defaulting to dports.  Follow the thread for more.

OpenZFS announced


ZFS was originally created at Sun and open sourced.  Sun was absorbed by Oracle and stopped being open (or even really existing), so ZFS was taken up by several separate groups – FreeBSD and Illumos being two examples.  OpenZFS has been announced, in part to provide common reference for other platforms that might implement it and probably to avoid capability fragmentation.  It’s certainly a good idea.

(If I have my history wrong, please correct me.)

Moving dports to gcc 4.7


DragonFly has two included compilers – GCC 4.4, and GCC 4.7.  Traditionally, we switch from one compiler to the other as default, and then replace the old one with a newer release, and so on.

Until recently, dports built almost exclusively using GCC 4.4.  John Marino’s switching to GCC 4.7, for a variety of reasons he lists in a recent post to users@.  An interesting point that he raises: GCC 4.4 won’t necessarily be replaced with a newer GCC, but perhaps clang?

TCP improvements


Sepherosa Ziehau has made a number of improvements to TCP in DragonFly – specifically, nonblocking and blocking connect(2) performance.  See each of his commits for statistics on how much this has reduced processor use under high load.  He has also written up an extensive description of how all this TCP stuff works in DragonFly.

In similar news, he has a nginx patch that delivers a significant performance increase.  It may go into nginx itself.

Jordan Hubbard and iXsystems coverage


Wired has an article up about Jordan Hubbard and his move from Apple to iXsystems.  It’s not a bad article, though it doesn’t delve into the why of BSD very much.  In any case, iXsystems has been really bulking up lately to be more than a generic hardware provider.

Speaking of which, that blade system going in now for dragonflybsd.org was sold by iXsystems.

Credential descriptors


Joris Giovannangeli, one of the Summer of Code students for DragonFly, posted his thoughts on credential descriptors – have a read.  He is working on capsicum and DragonFly, so this is a natural thought process.

Google Summer of Code Doc Camp


Every year, people ask “Why can’t writing documentation be part of Summer of Code?”  (Not necessarily for DragonFly, but in general)  Google has a “Doc Camp”, where a whole lot of documentation gets produced in sprints, and anyone can participate – not just Summer of Code students.

If this sounds interesting to you, your application has to be in by August 7th 9th.  (URL and date updated)

My dports upgrade experience


Since there’s a newer set of dports binary packages uploaded, I thought I’d spend my weekend upgrading, to catch up.

‘pkg upgrade’

And that was it.  Well, not really.  I had to dump and restore my Postgres databases, cause of the switch from 9.0 to 9.2 as default.  I had to build php5 from source to get the Apache module.  Those two things together took longer than the entire download and upgrade of the rest of my system – some ~200 packages?

SO_REUSEPORT speedups


Sepherosa Ziehau added SO_REUSEPORT to DragonFly.  I don’t know how the mechanism works, because he didn’t include a description, but he did include a explanation of just how much it reduces CPU usage during as-high-as-physically-possible network load.  He even wrote tools to test it more heavily.

Lazy reading for 2013/06/30


Some of the links this week go pretty in-depth.  Enjoy!

Your unrelated link(s) of the week: Candy Box and A Dark Room.  Both are text-only games, but they use HTML5 for animation.  They start minimal, and build up – be patient; there’s a lot of gameplay in there.  These minimal  games fascinate me.  It’s like reading a book, where it goes from just static text to an entire world being built.  (somewhat via)

8-way benchmarks for DragonFly and Linux


Phoronix has another set of benchmarks that include DragonFly and PC-BSD, along with several Linux distributions.  It’s interesting to see, though don’t take them as performance measurements.  7-Zip as a benchmark doesn’t describe much other than the program itself, and the Himeno benchmark results are because of the compiler in use rather than any underlying performance aspect of the operating system – for instance.  The DragonFly benchmarks disappear after page 3.

DragonFly 3.4.2 released


I’ve tagged DragonFly 3.4.2.  The major reasons for this point release were fixes for DragonFly under Xen with more than 2 CPUs specified, and for booting x86_64 DragonFly in KVM.  The 3.4.2 tagged commit has every detail.

If you’ve already got a working 3.4.1 installation, you don’t need to rush to upgrade; this is mostly for the people affected by the issues listed above.  I’m working on 3.4.2 install images; give that some time to complete and upload if you need one.

Postgres still crazy fast on DragonFly


Loïc BLOT posted about his benchmark of several operating systems using KVM and Postgres 9.1.  Happily, DragonFly is the fastest, with one exception.  Linux/ext4 comes out faster – if you run it with barrier=0, which can be dangerous in a non-battery-backed-up volume.

dports and gcc versions; an explanation


John Marino has a concise explanation of why dports mostly uses gcc 4.4 still to compile, even if you’re building DragonFly itself with the default 4.7.  It’s a reason to not use NO_GCC44 – yet.

entr(1); Run arbitrary commands when files change.


Eric Radman sent along a plug for a utility he is working on called entr(1).  The desciption is “Run arbitrary commands when files change.”  The site for it has several nifty examples – run make when *.c files change, or convert Markdown files to HTML as soon as they are modified.  The really nice thing about it is that it’s perfectly BSD-friendly, and uses kqueue, but will also work on Linux.  This beats the “This runs on the one flavor of Linux I use, in one particular shell!” approach I’ve seen from some other developers.  See the reddit discussion of it for comparisons to inotify.  No, it’s not in pkgsrc/ports yet.

Update: And thanks to Thomas Klausner, it’s in pkgsrc as sysutils/entr, and in ports as sysutils/entr thanks to Eitan Adler.  You have no reason not to try it now.

Running a spam blacklist


Peter Hansteen has an extensive writeup of how he has managed the bsdly.net spam blacklists.  Normally I’d stick this article in the Lazy Reading links, but the article is good enough to call out separately.   It’s excellent not just for the mechanical aspects of how the blacklists were maintained, but for his strict description on how the process is simple, verifiable, and transparent.  That last item, transparency, is how many anti-spam groups fall down.

DragonFly 3.4 release status


Here’s a status report on the 3.4 release, pulled right from my mailing list post:

  • We have the ability to use pkgsrc or dports (building from source in either case) now
  • Several people have committed the remaining last-minute fixes
  • I’m not going to have pkgsrc binaries built for the release.
  • dports binaries – John Marino and Francois Tigeot are uploading now.

I’d like to have the release available with binary packages for dports immediately, because I anticipate a number of people wanting to try it out. So, the release will be delayed a few days while the packages upload.
