Hammer and buffers


Are you running a Hammer filesystem on a low-memory system?  You may get some warnings.  It’s possible to tweak some settings to accommodate it, or just deal.

You unrelated comics link of the week: The Imitation Game, the story of Alan Turing, written by Jim Ottaviani and illustrated by Leland Purvis.  I have other work by both authors – they are excellent – and Alan Turning should be a name already familiar to you.

pf no longer single-threaded


Predrag Punosevac noticed that turning on pf was slowing his machine down.  Rearranging the rules fixed a lot of it for him.  However, Matthew Dillon decided it was time to make pf work concurrently instead of in a single thread, and 24 hours later, it does.  Quick, someone benchmark this!

DragonFly 3.6 to 3.8 upgrade note


If you are upgrading a DragonFly 3.6 system to 3.8, make sure you have the absolute latest version of 3.6 first.  A few people have had a crash during install of the new initrd, which leaves the system in an unbootable state.

There’s a fix now in 3.6 from Joris Giovannangeli, so updating 3.6 and then moving to 3.8 will ensure this doesn’t happen.  He posted a heads-up notice too.

(Why, yes, that is why shiningsilence.com was down for some hours today…  With Matthew Dillon and Sascha Wildner’s help, I was able to copy bits of /boot and /usr from a live CD back on disk and get online again.)

Try installing DragonFly again


Did you try to install DragonFly relatively recently and it never made it past the bootloader?  Apparently there’s a bug in some BIOS when using a smaller USB drive to install.  The loader checks multiple places for information, and if it checks somewhere that’s ‘farther’ than the end of the disk (i.e. 6G on a 4G USB key), the machine locks up.

Matthew Dillon and Kyle Davis spent a good number of hours figuring this out today, and Matt committed a fix.   So, if you were bit by this problem, try a -LATEST image about 24 hours from now and see if it works.

Lazy Reading for 2014/06/22


Again, a backlog from last week means this week is fat.

Your unrelated links of the week: My side hobby I never mention here is baking.  I looked up a word I didn’t know, found out about an ice cream type I’ve never seen, started reading about odd things to do with eggs and pressure cookers, and now I’m confused by the possibilities.  No narrative point here; I just need to get in the kitchen.

DragonFly 3.4 packages removed


The dports binary packages built for DragonFly 3.4 are removed.  If you have a 3.4 system, you can build from source, or preferably just upgrade.  Note that the 3.4 release images are still out there if needed.

DragonFly 3.6.3 tagged too


I tagged DragonFly 3.6.3, at Sascha Wildner’s suggestion.  Why do that when there’s a 3.8.1 out?  This way there’s a version of 3.6 that has all the fixes included, including the recent OpenSSL updates.  This ‘final versioning’ should probably be done for every release.  I’ll work on final images.

DragonFly 3.8.1 tagged


The 3.8.1 tag was planned for tonight; I’m waiting to find out if there needs to be a new set of binary ports for 3.8.1 before I tag.

I tagged DragonFly 3.8.1; you can see a list of the changes in the tag message.  New images are built. If you are already running 3.8.0, a normal make src-update and rebuild will get you everything.

mrsas(4) driver for LSI Thunderbolt added


Sascha Wildner has added the mrsas(4) driver, which works on a variety of LSI Thunderbolt devices – a variety of RAID cards, names for which are listed in the commit message.  Note that as of right now, these devices by default get taken by the mfi(4) driver, so you need to take extra steps to get mrsas(4) used.

DragonFly 3.8.1 by this Monday


Matthew Dillon posted a note about the next point release of DragonFly, coming within a few days.  Chunks of it like the recent OpenSSL and Sendmail fixes are already on the 3.8 branch. 

I assume I’ll be the one rolling it, and I plan to put together a 3.6.3 tag too, just so there’s a final version of 3.6 that has all changes rolled up.

Building with the system OpenSSL


If you’re building ports, it will treat OpenSSL as a dependency and bring in whatever version is available.  If perhaps you want to use the version of OpenSSL installed as part of your base system, Robin Hahling has the answer for how.  (This probably works on FreeBSD too.)

Some drivers gone for x86_64


Sascha Wildner has removed some drivers in the x86_64 config.  This will only really affect you if you use a custom kernel and still have entries for those drivers in the config file.

locking(9) man page added


Thanks to Markus Pfeiffer, there is now a locking(9) man page for use the next time you say, “Which is the right lock to use?”   Something I see almost monthly.

OpenSSL update


There were more problems found in OpenSSL… right after release of DragonFly 3.8.  OpenSSL 1.0.1h has been committed, thanks to Robin Hahling and Sascha Wildner.  I’ll be rolling a 3.8.1 release soon.

If you are saying “Hey, what about LibreSSL?  And do I write it LibReSSL?”, it’s not set up as a portable release yet.  Also, I don’t know the correct capitalization, either.  There is some debate about the lack of notification from OpenSSL to LibreSSL, though other vendors were notified days before.

DragonFly 3.8 released


The 3.8 release of DragonFly is out!  See the release page for a changelog and check your local mirror for download first.

Binary dports packages for 3.8 have been built; they are available for download.  (link goes to release versions of the packages.  Future updates will be in ../LATEST)

For upgrades from 3.6: You can pull the 3.8 source normally with git:

cd /usr/src
git fetch origin
git branch DragonFly_RELEASE_3_8 origin/DragonFly_RELEASE_3_8
git checkout DragonFly_RELEASE_3_8

Assuming you are using an unmodified kernel, here’s the steps I usually do for an upgrade:

# make buildworld && make buildkernel && make installkernel && make installworld && make upgrade

After upgrading from 3.6, pkg (as designed) will download the appropriate 3.8 packages with pkg upgrade.

Confluence on DragonFly: works, sometimes


I’ve seen Atlassian Confluence, a Java-based wiki program, in a few places.  Atlassian apparently offers their software at a discount (free?) to qualified open source projects.  I set up Confluence 5.4 on DragonFly as a test run, and it generally worked.  That’s great!  I tried to set up version 5.5, and it will not start.

May 08, 2014 7:24:41 PM org.apache.catalina.core.ContainerBase startInternal
SEVERE: A child container failed during start
java.util.concurrent.ExecutionException: java.lang.InternalError: platform not recognized
        at java.util.concurrent.FutureTask.report(FutureTask.java:122)

This is annoying. DragonFly (or any BSD) is not supported by Atlassian for Confluence, so it’s not a surprise… but I was so close! Their product has a very nice interface and I was planning to replace Mediawiki at my workplace with it, for some internal documentation. This FreeBSD bug report is the closest fix I can find, but it’s old enough it shouldn’t matter now.
