Sascha Wildner’s posted an update to the acpi_asus(4) module, so it’s worth updating if you have an appropriate Asus machine and are running DragonFly-current.
Thanks to the efforts of John Marino and others, pkgsrc is having possibly the highest success rate ever of successful package software builds. If only I could get a pkgsrc-2012Q1 build to complete and upload…
You’d think everything that could be done with grep has already been done, but no: grep, which is an externally-produced program, has been updated in DragonFly to version 2.12 by John Marino.
A few recent updates imported to DragonFly from FreeBSD: Francois Tigeot updated amdsbwd(4), an AMD south bridge watchdog. Sascha Wildner updated arcmsr(4), the Areca RAID controller driver, and Peter Avalos updated pw(8).
In the other direction, FreeBSD now has GNU hash support for rtld, based on John Marino’s work in DragonFly.
Venkatesh Srinivas has been working on integration of Tim Bisson’s virtio-bhyve drivers into DragonFly. This would make throughput better in KVM/Qemu. His bug ticket has some questions that could use answers.
Francois Tigeot has added ichwd(4), a driver for the watchdog function on some Intel ICH motherboard chipsets. Sascha Wildner has also made the kernel option for it on by default. (Look for /dev/wdog.)
Update: Francois Tigeot sent a link to an excellent page explaining hardware watchdogs.
Here’s a post by yours truly, on how to move to pkgsrc-2012Q1 though building from source. This is for anyone sick of waiting for me to finish the binary build of pkgsrc.
Matthew Dillon posted a followup on that fix for clustering I noted yesterday. It describes the exact problems better than I could, though the result is the same: you should update if you’re running bleeding-edge DragonFly.
A fix for cluster_write() issues reported by multiple people is now available, so if you’re running a version of DragonFly newer than 3.0.2, you’ll want to update.
Each of the 4 DragonFly participants for Summer of Code have posted an introductory email and details of their projects. Here’s direct links to their posts for your reading convenience:
- Vishesh Yadav – Implement inotify interface and Indexing Service for Filesystem
- Mihai Carabas – Add SMT/HT awareness to DragonFlyBSD scheduler
- Loganaden Velvindron – Privilege Separation in DragonflyBSD
- Ivan Sichmann Freitas – 32 bit API for 64 bit kernels
(Yes, same format as my last post, but now the links are to their posts, not the sparse Google info pages.)
Sepherosa Ziehau added “Rescue Retransmission for SACK-based Loss Recovery Algorithm” in a commit, where he details just where this would be handy. It’s on by default and the sysctl net.inet.tcp.rescuesack can be used to turn it off.
Welcome our newest committer: Markus Pfeiffer. He’s ‘profmakx’ on EFNet #dragonfly, and has been working on a port of FreeBSD’s USB infrastructure – which I am looking forward to, tremendously.
Google has announced their projects accepted for Summer of Code: DragonFly has 4 projects of the 1,212 funded:
- Vishesh Yadav – Implement inotify interface and Indexing Service for Filesystem
- Mihai Carabas – Add SMT/HT awareness to DragonFlyBSD scheduler
- Loganaden Velvindron – Privilege Separation in DragonflyBSD
- Ivan Sichmann Freitas – 32 bit API for 64 bit kernels
(Hopefully those links are to visible pages) We had way more good proposals than available mentors/slot, unfortunately. So if you didn’t get in, think about next year, or maybe look at doing the work on your own; there’s some great ideas out there that I’d like to see happen.
Mosh, mentioned on this Digest a few weeks back, is now installed on leaf.dragonflybsd.org. If you’re doing any development work there but dealing with a relatively high latency, this should help. (Thanks Venkatesh Srinivas.)
I’m still working on building them. I kept getting panics, which seem to be fixed by this commit, so I should have something soon. Sorry!
Peter Avalos has updated OpenSSL in DragonFly to version 1.0.1a, to fix the recent vulnerability CVE-2012-2110. Thanks Peter!
Francois Tigeot has followed up with a description of how to enable and disable quotas on DragonFly, which will work for most any local file system, unless rebooted. There’s also the vquota(8) man page.
Based on a recent post from Chris Turner to the tech-pkg@netbsd.org mailing list, here’s a bug report that should get you to a working lang/OpenJDK7 pkgsrc package.
DragonFly now has a optimized scoreboard for SACK, thanks to Sepherosa Ziehau. What’s that mean? SACK is a way to make sure only the needed parts of a TCP transmission get retransmitted, when multiple packets are lost. The scoreboard is where the packets needing retransmission are tracked. So, the result of these improvements is better performance in packet-lossy situations.
