In Other BSDs for 2014/07/12

Finally, a much more eventful week.  I already noted LibreSSL’s release.

Portable LibreSSL out

The portable (meaning ready to be brought into other operating systems) version of LibreSSL is out.

BSDNow 045: ZFS War Stories

BSDNow episode 45 is up.  This one is an interview with Josh Paetzel of iXSystems.  No tutorial this week because Allan Jude is at the devsummit in the UK, an event I totally did not know existed.

pkg and conflicts

Some dports packages can’t be installed in combination with others.  The easy way to find the conflict without doing the install?  Look for CONFLICTS= in the Makefile.  If you don’t have the dports tree on disk, you can always look online.

LDAP on DragonFly

If you’re looking to use LDAP on DragonFly, follow this thread (read the first, keep going) as people talk about implementing it, what they installed, etc.  I haven’t tried it myself, yet.

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).

ACPICA updated to 20140627

ACPICA has been updated by Sascha Wildner to version 20140627, which as you can guess from the version, is the most recent.   See the included changelog for what’s different.

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.

In Other BSDS for 2014/07/05

BSDNow 044: Base ISO 100

The 44th BSDNow episode is out, with an interview of Craig Rodrigues, a tutorial on creating pre-patched OpenBSD ISOs, and the usual discussion of news items, including DragonFly’s recent pf changes.

(I don’t get the pun in the title this time, darnit.)

Default DragonFly/pf keep-policy changed

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

set keep-policy keep state (pickups, sloppy)

This is to match other BSDs (which?  I don’t know) and reduce overhead, according to the commit.

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!

2014-07-02 – Introduction to Timekeeping, Steven Kreuzer

6:45about.com (1500 Broadway enter on 43rd Street, 6th Floor)
Notice: RSVP to rsvp at nycbug.org and bring photo ID. RSVPs must be
received by 2 PM, day-of.

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.

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.

Lazy Reading for 2014/06/29

I bring the audio and the visual today.

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.

Books discounted at O’Reilly

O’Reilly is running a 50% off special on a variety of books on electronics, with coupon code WKECTRC.  I’m posting it now because it only lasts for this week.

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.

Posted by     Categories: DPorts, DragonFly     0 Comments

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.

Posted by     Categories: DragonFly, Goings-on     0 Comments

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.

Random number generator changes

The obvious joke should be “how can you tell?”  Anyway, the csprng in DragonFly has been updated and IBAA is being used more often, and there’s more updates on the way.

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.

BSDNow 041: Commit This Bit

BSDNow 041 is out with an interview of Benedict Reuschling, along with a lot of news discussion and some interesting NAS notes.  Hey, I’m mentioned!

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.
