Recent Hammer2 work


Matthew Dillon has been doing a lot of Hammer 2 work lately.  Well, he’s been doing it for quite some time, but the recent commits contain the sort of things that are easier to link to, like deletion speedups, freemap changes, and stats tracking/compression results.

Recent dragonfly-master users: update


If you were running a version of DragonFly 4.1 (i.e. the master version, not release) built between the 20th and 25th, rebuild.  There’s a UFS bug introduced in that short timeframe.

If you are running 4.0.x release or built your version of DragonFly-master outside of that date range – you are unaffected.

Haswell +, power–


A recent commit from Matthew Dillon means users of Intel Haswell or later CPUs will see reduced power usage, if I’m reading this commit correctly.

Hammer abort-cleanup added


Hammer will perform daily housekeeping tasks each night.  If you’re up late enough, it may kick off while you are working.  If you want to stop the process after it’s already started (since it’s disk-intensive), John Marino has added the ‘abort-cleanup‘ command.

A scanning tip


If you want to use a scanner on DragonFly, install SANE.  That is apparently all you need to do.

Automatic encryption of swap


Experimental automatic crypting of swap is now available in DragonFly-master.  Recently added, though it may have been possible another way.

A leaf falls, briefly


leaf.dragonflybsd.org, where the DragonFly website is hosted, is temporarily down while a disk is replaced.  Images and binary packages are still available.

Minnowboard and DragonFly


This may not be a huge surprise, but the Minnowboard MAX can run DragonFly just fine, modulo some dmesg complaints.

Shut up ARP


Sepherosa Ziehau has introduced a new sysctl:

net.link.ether.inet.log_arp_creation_failure

Set this to zero and you won’t get endless ARP events from networks you aren’t on.  For example, I’m hooked up to a cable modem.  I only get a public routable IP address, but the network used for the cable modem network itself bleeds ARP packets out where my DragonFly machine can see it.  Since it’s on a different network segment than the address I receive through DHCP, it always fails and the system logs it.  For example:

May 11 05:20:52 www kernel: arplookup 100.68.112.145 failed: host is not on local network

I can’t do much about it since that layer 2 leakiness is going to happen, but I can shut it up with this sysctl – and thank goodness, cause I’ve been seeing these messages since first using a DOCSIS modem in… 2001 or so?

Broadwell support, other video changes


Francois Tigeot has committed his Broadwell work, which has a longer-than-I-realized list of benefits.  Does anyone have a 4k screen to try?

More Intel video testing


If you’re running DragonFly-master and you have an Intel video chipset, Francois Tigeot has an update for you.  It brings accelerated Intel video up to match the Linux 3.14 version, adds Broadwell chipset support, and should generally improve performance.  He lists how to test right in the message.

Hammer spreads via GSoC


DragonFly committer Joris Giovannangeli has a Google Summer of Code project.  He’s bringing Hammer2 to OpenBSD, in single-node form.  It’s a very difficult project, but Joris is a very talented worker.

Reblock all the things!


Tomohiro Kusumi has been quietly making a lot of commits to Hammer.  I haven’t been linking them because they don’t necessarily equate to new features, but here’s an recent exception: the -A argument will make your Hammer command run on every PFS.  It only affects reblocking/rebalancing – for now.

NFS and Hammer slaves


You can now export Hammer slave volumes as NFS mounts – but since slave volumes are updated from master, you’re mounting a snapshot of that point in time.  That may actually be an advantage.

Building only one compiler


DragonFly builds two compilers by default.  If you weren’t interesting in building both, there were switches to build only the default, like NO_GCC47.  This changed with every compiler update.

With the switch to GCC 5, the new switch is “NO_ALTCOMPILER”.  That will last through compiler changes.  I’m mentioning this now because sooner or later, you’ll want to gain back some time on a buildworld.

GCC 5 released, switched


DragonFly now has GCC 5.1 release.  If you are running DragonFly master (i.e. 4.1), you’ll probably want to both rebuild world and kernel, and update your packages so they all match.  There’s already packages built with GCC 5.1, so binary package upgrades can happen quickly.  There’s GCC 4.7 packages still available if you aren’t making the jump yet.

If you’re on DragonFly 4.0.x – nothing’s changed.

CPU, RAM temperature monitoring


I’m late posting about these, but they go together: Sepherosa Ziehau has added the ability to read CPU temperature through various sysctls, and the same for DIMM temperature readings.

Extra reading on page coloring


Here’s some comments from Matthew Dillon on page coloring in DragonFly; a topic that comes up every year for some reason.

GCC 5.1 release candidate added


The release candidate for GCC5 (5.1.0) is out, and it’s in DragonFly too.  It’s not yet switched over to run as the default – that’ll require the release.

Posted by     Categories: DragonFly, Goings-on     0 Comments

Changing to gcc 5.0


The default compiler in DragonFly is going to change over from GCC 4.7 to GCC 5.x very soon, to match the GCC 5.1 release.  This means that packages built for DragonFly-master won’t be compatible with the old ones.  You will need to reinstall packages when you next ‘pkg install’.  John Marino has an extensive writeup detailing what’s needed, and the actual change is some days off.

If you are using DragonFly 4.0.x (the release), this doesn’t affect you at all.

i915 update to try


Francois Tigeot has a new update to the drm/i915 driver for testing.  It matches, feature-wise, what’s in Linux 3.12.  Try it if you’ve got the hardware.  (and dragonfly-master)

Periodic reports on DragonFly


I have had trouble with my daily/weekly periodic reports never making it to my GMail account.  Sascha Wildner pointed out to me that periodic.conf has its own answer already:

daily_output=”/var/log/daily.log”
daily_status_security_output=”/var/log/security.log”
weekly_output=”/var/log/weekly.log”
monthly_output=”/var/log/monthly.log”

… and newsyslog is already set to take care of them.  There’s more in the periodic.conf man page.

 

DragonFly on Vultr


There’s been some linking to the updated HAMMER2 design document.  The Reddit link doesn’t have anything specific, but the Hacker News one has some details (including a credit code!) for installing DragonFly on a Vultr VPS.

BSDNow 084: pkg remove freebsd-update


This week’s BSDNow talks with Baptiste Daroussin about developing and using pkg, for ports and for packaging the base FreeBSD system.  (Baptiste has been seen on #dragonflybsd, since pkg is on DragonFly, so I’m sure there’s some relevant bits there, too.)  There’s also the usual news summary.

Hammer and Hammer2 details


I haven’t been drawing enough attention to it, but there’s been a bunch of HAMMER filesystem activity lately: First, Tomohiro Kusumi has been working on HAMMER – these posts are a small subset of his commits.  Second, Matthew Dillon has been working full steam ahead on HAMMER2.  The HAMMER2 design document has been updated (read this!), and he’s already accomplished master->slave disk syncing.

It’s not ready for production, of course, which you may already realize, so don’t install it unless you want to work on the code.

In Other BSDs for 2015/04/04


If you’re part of a BSD user group, please let me know your schedule.  I’m able to catch NYCBUG announcements cause I’m on their announce@ mailing list – but I could use more.

Info pages gone


Do you use info pages?  Yeah, me neither.  John Marino’s removed or converted the various info pages already in DragonFly, and removed texinfo since it’s no longer required.  (I’ve linked to a few examples, but there were a number more commits than this.)

Blue bug, new shell


The default .cshrc in DragonFly has had some changes, which shouldn’t be anything but handy… assuming you are using tcsh.  Also: the loader menu defaults to a blue Fred, now.

New binutils, faster build


In the process of committing binutils 2.25 to DragonFly, John Marino also broke its build into parallel parts and removed the build of the gold linker.  Buildworlds should be noticeably faster now, though I don’t have a before/after.

New wireless documentation


John Marino’s written an extensive page about wireless and DragonFly, on dragonflybsd.org.

Keymap details


If you’re looking to change your DragonFly system’s keymapping to support a non-US character set, use this users@ post from Adolf Augustin as a cheat sheet to make all the right changes.

Clustering and copies in HAMMER2


Matthew Dillon answered some mailing list questions on how clustering and data copies will work in HAMMER2 – no due date, of course, because this is very complex.  If you’re really into it, there’s always watching the recent commits.

New locking and synchronization docs


Matthew Dillon has rewritten the Locking and Synchronization documentation for DragonFly.  Keep this in mind the next time you say “Which lock should I use for this new software/ported software?”  There’s also locking(9).

A PHP upgrade note


The other day, I updated some packages using pkg.  The default version of PHP went from 5.4 to 5.6.  I ended up doing what /usr/dports/UPGRADING says and making a list of all PHP packages on my system, before removing PHP and its dependencies.  I then reinstalled the packages that used PHP, bringing the needed packages back in at the right version.  pkg 1.4 didn’t handle the transition cleanly, unfortunately.  I also had to specify mod_php56 because pkg was trying to get the 5.4 version despite it not being default.

None of these are insurmountable problems, but it never hurts to be forewarned.  pkg 1.5 is on the horizon and may have an easier time with sorting these types of dependency/version changes.  This may apply to FreeBSD in addition to DragonFly.

DragonFly 4.0.5 out


I’ve tagged version 4.0.5 of DragonFly, and it’s available at your nearest mirror.  This revision is mostly to incorporate the newest OpenSSL security bump.

Posted by     Categories: DragonFly, Goings-on     2 Comments

New OpenSSL so new point release


OpenSSL has yet another security update, and Sascha Wildner has added it to DragonFly.  It probably justifies a 4.0.5 release, so I’ll be working on that.

Matthew Dillon pulled in a new USB update from FreeBSD to DragonFly.  What does it change?  I’m not completely sure, but he did it to get apcupsd working, so that may be a hint.

HDMI sound trick


If you have a HDMI-connected monitor, but no sound, this trick about increasing available memory may help.

DragonFly 4.0.4 out


DragonFly 4.0 has had a minor point release, to 4.0.4.  There was a bug in the initial install where the rescue image installed on disk would be incorrect.  This was fixed after the first time a build/installworld was done, but might as well have it start out right.  There’s some other small fixes, and the release commit will show you the summary.  Download from your nearest mirror or update normally.

Sendmail removed, DMA added


John Marino has removed Sendmail from DragonFly (as part of the base system), and replaced it with DMA, the DragonFly Mail Agent.  If you just need delivery to local users, DMA will do the trick.

The announcement message covers what you need to do to deal with it (potentially nothing), and there’s more in-depth documentation to cover how to switch if you need more full-featured software.

Did you upgrade DragonFly on the 25th?


If you are on DragonFly-master and you upgraded during select hours on the 25th of February, you may have been bit by a makefile error.  The fix, as listed in that link, is simple:

If you are not on -master or you did not upgrade in that timeframe: never mind.

DragonFly GUI resurrected


Michael Neumann has switched out pkgsrc packages for dports packages for building DragonFly with a GUI.  There’s no built image to download right now, but I’m optimistic the next release will have it.  You can build it now on a DragonFly system using src/nrelease.  With all this video work going in lately, it will give us something to show.

Radeon updates, too


If you’ve been sitting with a Radeon-based video card and wishing you had all the nice updates i915 users are getting, today is your lucky day.  Michael Neumann has brought Radeon support equivalent to Linux 3.9 into DragonFly, and he has a 3.10 branch for testing if you feel adventurous.

In Other BSDs for 2015/02/21


There’s some DragonFly material in here, though I normally confine that to the rest of the week.  It’s inextricable from the rest of the links.

memtemp(4) update


I admit I never thought about it much, but I’ve also never had enough RAM to matter: there’s a memtemp(4) tool that monitors temperature sensors for your system’s memory.  Sepherosa Ziehau has updated it on DragonFly to support some newer processor setups.

Really turning off Sendmail


This bites many people sooner or later: you think you’ve turned sendmail off, but it still gets opened up on your system.  The answer: sendmail_enable=”NONE”.

(It should support sendmail_enable=”NOPE”.)

SSDs and disk wear


Several of the DragonFly machines used for building packages and/or releases have SSDs, and have been vigorously exercising those disks for some time.  SSDs are supposed to have a shorter lifetime than spindle-based hard drives.  However, Matthew Dillon found that there’s surprisingly little wear on those SSDs.  This empiric information was noticed in several places.

HEADS UP: pkg will eat itself


Well, might rather than will , but I had to make a music reference.  There’s a bug in versions of pkg from 1.4.6(ish) to 1.4.11 that can make it accidentally delete itself while updating packages.  If this happens to you, there’s an easy fix, as posted to users@:

# cd /usr && make pkg-bootstrap

Once you’re on version 1.4.12+, you’re fine.

em(4), emx(4) updates


If you have a em(4)/emx(4) card, AKA ‘Intel(R) PRO/1000′, Michael Neumann has an update for you. It’s from Intel’s 7.2.4 release of the code.  This is to support the new I218 cards.  Initial reports are positive.

DragonFly and Git


DragonFly is the only BSD, I think, to switch fully to Git for version control, and Matthew Dillon wrote up how DragonFly uses Git.

Many wireless updates


Matthew Dillon brought in some wireless networking updates – the ath(4), iwn(4), and wpi(4) drivers are updated.  There’s porting notes if you need them, too.  In related news, rum(4) is also improved.  The updates apparently benefited DragonFly and FreeBSD at the same time.

More i915 upgrades

NFS and alc(4) improvements


If you have very recent alc(4) hardware, it may be supported now.  If you are booting over NFS, it may be faster now.  These changes are unrelated other than both being recent – NFS is improved for any chipset.

powerd refinements for DragonFly


powerd now can be adjusted on DragonFly, for quicker returns to high CPU frequencies, or slower … slowdowns?  It’s quickly quick or slowly slow.  That’s not the best explanation, but I like rhymes.  For a less stupid description, look at the man page, which now includes usage examples.

i915 improvements to test


Francois Tigeot has updated the drm/i915 code again, matching Linux 3.10 for feature level… but it’s a big update.  If you are

  1. Running DragonFly-master
  2. Using a i915 chipset
  3. (optional) On a chipset that is not Haswell or Ivy Bridge

… He could use your testing and feedback.

ISO/IMG files for DragonFly 4.0.3 have been uploaded and by now should be available on your favorite mirror.  You should update for the OpenSSL upgrade.  If you already have DragonFly 4.0.x installed, the normal ‘make buildworld && make buildkernel && make installkernel && make installworld && make upgrade’ cycle should work just fine.
