BSDNow 242: Linux Takes The Fastpath
BSDNow 242 has no interview and the normal wide range of topics: TrueOS, F-Stack, jails, SmartOS, and most interesting to me, open source business model development with iXSystems.
New core team member – Taylor C...
After nearly 13 years on the NetBSD core team, Yamamoto Takeshi has decided
to step down. yamt has been a regular contributor to NetBSD, and we would
all like to thank him for his work, helping guide the project to where it
is now. It is safe to say that NetBSD would not be the same without his
quiet and (Read more...)
HAMMER2 dirty vnode management
A ‘dirty’ vnode is a disk data reference that has changed but hasn’t yet been committed to disk. This pair of commits adds a syncing threshold, useful for anyone with slower disk resources. Remember, disks lie.

Hardware accelerated AES/HMAC-SHA on ...

on octeon CPUs, much like AESNI for x86s.
I decided to test tcpbench(1) and IPsec, before and after updating and enabling the octcrypto(4) driver.

More cross-pollination
I like code that travels through multiple BSDs.
pkg-provides on DragonFly
There’s a plugin for pkg, called pkg-provides, which will tell you what package(s) contain the filename you provide – installed or not. I didn’t even know pkg had a plugin system. Anyway, it works on DragonFly, as the author notes.

OpenBSD Errata: April 14th, 2018 (per...
Errata patches for perl have been released for OpenBSD 6.1, 6.2, and 6.3.
Heap overflows exist in perl which can lead to segmentation faults,
crashes, and reading memory past the buffer.
Binary updates for the amd64, i386, and arm64 platforms are available
via the syspatch utility. Source code patches can be found on the
respective errata p [...]
In Other BSDs for 2018/04/14
Totally last-minute summary, but I’m hitting every BSD category.

The machine room that lists.openbsd.org is in will be undergoing
maintenance Saturday April 14th. As a result, the list server will
be taken down at 6:00am MDT. It will be back up by 5pm MDT at the
latest.
This also affects ftp.usa.openbsd.org (aka anoncvs3.usa.openbsd.org)
which is located in the same machine room.

vis, unvis, across BSDs
I haven’t been able to say this in a while, but: I like cross-pollination.
ipfw3 in rc
For anyone wanting to try out ipfw3, there’s now a rc script. Make sure to set up a rules file, or you’ll kill all incoming traffic.
DragonFly 5.2 released
DragonFly 5.2.0 has been released. Spectre/Meltdown mitigations are in there, along with improvements for HAMMER2, accelerated video, and ipfw. My users@ post has the details on upgrading, as does the release notes.
