i915, Baytrail, and C-states


Daniel Bilik has found there’s an issue with i915 acceleration, Baytrail CPUs, and some AUTODEEP low-power states.   This will only affect you if you are using that specific hardware combo and setting certain low power modes.  Interestingly, it affects other platforms, too, as it appears to be a symptom of how the video is addressed, not a DragonFly-specific bug.

BSDNow 131: BSD Behind the Chalkboard

NYCBUG tonight: BSD init(8) and rc(8)

BSDNow 130 and Garbage 15 podcasts


Normally I’m just linking to BSDNow, but there’s even more BSD-themed media coming up today: BSDNow 130 is out, titled “Store all the Things“, with an extended summary of the recent Storage Summit.

Garbage episode 15 is out, titled “Compressing with Broccoli“.  It notes a lack of activity for Bitrig – I still see commits happening, though.

High-availability sync for ipfw3


Bill Yuan has added ‘ipfwsync’ to ipfw3 in DragonFly.  As you may expect from the name, it’s a way to sync ipfw3 configurations across multiple devices.

Default shells and library changes


I see this bite people irregularly over the years: if your default shell on login can’t run, what do you do?  I’ve seen it happen because of a missing /usr/lib, and it can happen with out-of-date library references, too.   There’s several different ways to deal with it:

That last one may be useful if your dports setup gets mangled, somehow – though ‘pkg upgrade’ has always worked for me.

DragonFly i915 support: another upgrade


Francois Tigeot has again updated Intel i915 video support in DragonFly, bringing it even with what’s in Linux 4.2.  This will be very useful for Broadwell and Skylake users, and even Broxton, apparently the newest Atom platform.

DragonFly 4.4.2, a bugfix release to 4.4.1, is out.  This was mostly prompted by the recent OpenSSL update, but other little fixes have made it in, too.  It’s available for download and is probably available at your nearest mirror by now, if you want an image.  The release page is updated, and there’s always the Git tag summary for 4.4.2 for the most exact details.

Who still wants a shirt?


I have DragonFly shirts, helpfully printed up by Sepherosa Ziehau in China.  I have a list of people that are interested in shirts, most of whom remembered to give a shirt size.  I don’t have anyone’s email address or mailing address on that list.

If you are on that list, send me your mailing address.

The shirts are marked L/XL/XXL/XXXL, but they run smaller than U.S. versions of those sizes.  I usually find a U.S. XL shirt baggy, but “XXXL” is the one that fit me, for instance.  I’ll do my best to place the appropriate one.  This is just an advance apology, since it’s too late to change anything if it turns out tight.

I’ll mail these out as I have the spare cash and time on hand.  (I hope most of you live in the continental U.S.)

Whole lotta reading


Rimvydas Jasinskas has consolidated/restored/updated a large number of papers into share/doc on DragonFly.  I’m not going to link to his large number of commits, but instead point you at the directory where they all went.  There’s a number of design documents in there that date back to 4.4BSD and beyond (and some much newer), which may interest or educate you.  Of special note: The Guide to the Dungeons of Doom, for rogue, or the KAME IPv6 implementation notes.

Debugging tips


If you’re building from dports, and you want to include debugging information, you’ll want to put ‘WITH_DEBUG=yes’ in /etc/make.conf.  Note that this affects anything you build at that point, including world, which you’d want to rebuild anyway.

Printing tips


These probably apply cross-BSD, but in this case, it’s DragonFly tips for printing with CUPS.

More on privatization


For those of you running DragonFly-current, the already-mentioned library privatization going on means that ports have to be rebuilt.  You will want to do it yourself, or wait a little bit before upgrading if you want to install binaries.

Privatization means rebuilds


That’s a pretty cryptic headline, isn’t it?  John Marino has ‘privatized’ several libraries in DragonFly, so that they can’t get included involuntarily as part of a port build.  That may mean you will need to perform a full rebuild of your system if you are tracking DragonFly-current.

(This is the way to fix ‘system’ languages like Perl was in FreeBSD 4.x – keep them clearly separate from the port version.  It’s about a decade too late for that idea to work out, though.)

There’s two important security updates for SSH.  DragonFly release and development have been updated for it, and you can correct for it on your running system using the one-liner at Undeadly.

Note: keep in mind this is a client bug – it’s an information leak when you as a client connect out to somewhere else.  A server, as an endpoint, is not affected.

Qemu fixes, and a bonus


A number of people have reported problems with qemu and DragonFly, both running locally and on a host.  It turns out to be a problem with the getcontext(), setcontext(), and swapcontext() functions, but Matthew Dillon fixed it in a way that doesn’t affect performance very much.

That apparently wasn’t good enough, so he added _quick versions of those same functions, so it became not just a fix, but an improvement.

In related qemu news: qemu-devel can use vknetd similar to a vkernel, now.

New DragonFly installer disk arrangement


The DragonFly installer has been modified to produce disk arrangements that will generally match between UFS and Hammer installs, plus directories where you usually don’t want Hammer history or backups (like /tmp or /usr/obj) are now under /build and null-mounted to where you’d expect, since null-mounting works transparently well on DragonFly.  Matthew Dillon has a note explaining the whole thing.

You need to provide some way for me to contact you – preferably email, and the size you’d want.  (Use the Land’s End Men’s Shirts chart for sizing, because why not.)  I’ll only have a few, so no guarantees.

Update: I have more responses than probable shirts at this point – sorry!  I’ll get in contact with each of you once the shirts come in and arrange delivery.
