DragonFly 3.8.2 images uploaded

It took me a little while, but DragonFly 3.8.2 images are uploaded now to the main site.  Check the 3.8.2 changelog if you didn’t before.  This is a recommended upgrade for the newer OpenSSL, and should otherwise have little impact on the programs you have installed.

Haswell GPU support in DragonFly

There’s been good progress in Francois Tigeot’s work on Haswell graphics support in DragonFly.  If you have one of those newer units, you should be able to use the i915 driver with it now – as long as you keep acceleration off.  (You won’t notice any difference in 2D anyway.)

DragonFly 3.8.2 rolled

I’ve tagged DragonFly 3.8.2, which exists mostly to accommodate the latest release of OpenSSL.  (Security fixes, which should not be a surprise.)  I will build images as soon as I get a chance.

drm/i915 support update

If you have a i915 video chipset (which appears to be most every recent laptop), Francois Tigeot would like you to try his huge patch.  It doesn’t support Haswell chips yet, though it lays some of the groundwork for it.

pkg 1.3 out

There’s a new version of pkg out – 1.3.  (via)  That’s an announcement on the FreeBSD-ports-announce list.  Since DragonFly also uses pkg, that means it’s available for DragonFly too.  John Marino reported on IRC that he’s testing a bulk build now, using it on DragonFly.

There’s a lot to read this week… I’m not sure how that happened.

Your unrelated comics link of the week: Mmmm…  diagrams.  That describes me.  The subject and artist, Scott McCloud, has a book called Understanding Comics that is an excellent discussion of perception and communication.  His exploration of visual “closure” is good for anyone who has to think about interfaces.

Hammer and mirrored disks

A frequent question people ask when trying Hammer is “How can I do software RAID to cover a disk failure?”  Hammer provides for streaming one volume to another, so you can duplicate drives, but there isn’t an automatic failover mechanism as there is with a RAID setup.  The first answer is usually “get hardware RAID“; my preferred solution.   The remaining software solutions are vinum, ccd, and lvm for DragonFly.

BSDTalk 243: Ingo Schwarze

It’s all multimedia day here, as BSDTalk 243 is also out with 16 minutes of conversation with Ingo Schwarze about mandoc.  Mandoc is the man replacement in OpenBSD and built-but-not-yet-used in DragonFly.  ‘man replacement’ is probably an oversimplification.

Improvements for qemu

While Matthew Dillon was testing the new up-to-256-processor support for DragonFly, he added a few sysctls, one of which helps qemu performance when emulating a lot of processors.  I note it here in case it’s helpful to someone else.

Interlock Roc: Linux Workshop

There’s an open source meetup at a hackerspace near me, happening tomorrow.  Well, today by the time most people read this.  Anyway, it’s at Interlock, starting at noon.  I don’t think I’ll make it, but I’m always happy to see this stuff happen in my own town.

Reserving more memory

DRM (Direct Rendering, not Digital Rights) on DragonFly will normally eat all the memory it thinks it needs.  However, vm.dma_reserved can now be set to a fixed limit in /boot/loader.conf.   By default, vm.dma_reserved on DragonFly is set to 16M, and can be set higher.  I think this is necessary when running higher-resolution screens… Don’t quote me on that, though.

SYSRET fixed even if not broken

There’s a recently talked about bug in SYSRET that apparently affects a lot of operating systems, including Linux and several BSDs.  It looks like DragonFly is not affected, but Matthew Dillon has put in changes just in case.

More i915 updates

Francois Tigeot has been working on making i915 video support work better; with his latest update, it’s worth trying the Intel-specific driver instead of vesa if you have both the 915 chipset and are running X.

Heads up: changing mfi to mrsas

The mfi(4) driver has had some data corruption problems on “Thunderbird” series RAID controllers.  There’s a newer driver, mrsas(4), that replaces mfi(4) for these controllers and does not have these issues, but switching may mean new drive locations and therefore some work to get booting correctly again.  Sascha Wildner has an extensive writeup about what this entails, and how to switch now if you have that hardware (recommended).

DragonFly x256

DragonFly now supports running on up to 256 CPUs.  256 is the initial limit on the basic interrupt controller, and it can be extended further.  It’s been tested on 255 CPUs so far, since that’s the highest number of CPUs you can bring up in qemu.

Default DragonFly/pf keep-policy changed

Matthew Dillon changed the default keep-policy in DragonFly to:

How to keep Hammer empty

A note for everyone: use Hammer default on a very busy filesystem, and you will eat a lot of disk space since all file changes are recorded.  (I’ve done this to myself a few times.)  Francois Tigeot has a list of tips on how to keep that from happening.

NYCBUG: Introduction to Timekeeping, 2014/07/02

I am pasting the announcement verbatim because NYCBUG is having some hardware issues with their mailing list archive.  It’s interesting for both subject matter and because you get to see the inside of about.com.  RSVP soon so you can get in!

Abstract

Time is a funny thing. You can spend it, save it, waste it and kill it,
but you can’t change it and there is never any more or less of it.
Everyone knows what it is and uses it every day but no one can seem to
define it.

In this talk I will provide a brief introduction to time, timekeeping,
and the uses of time information, especially in scientific and technical
areas.

One more CPU on DragonFly

The max number of CPUs on DragonFly just went from 63 to 64.  This is really just a side effect of preparation to move up that limit, but I am entertained by the single-digit bump.

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.

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.
