The commands rcp(1), rlogin(1), rlogind(1), rsh(1) and rshd(1) have been removed from DragonFly. There’s a net/bsdrcmds port if you still need them… though I imagine/hope ssh is filling the void for everyone.
I say “one more” like I know when this saga will end. If you are using the devcpu-data port to update your processors, you’ll need to add
to your /etc/rc.conf, as Sepherosa Ziehau points out.
This is almost all link overflow from last week – and next week’s edition is almost complete. There’s a lot to read lately!

The regular maintenance scripts for HAMMER1 assume that it’s mounted at the time of cleanup. If you have them unmounted, they won’t go through that regular maintenance, but it’s easy enough to fix.
Matthew Dillon posted a summary of IBRS and IBPB support in DragonFly, and some numbers showing its impact in various configurations of options and CPUs.
Are you tired of hearing about Meltdown/Spectre yet? Doesn’t matter! The two sysctls for controlling mitigation in DragonFly have been renamed:
They go to hopefully sensible defaults, but Matthew Dillon has done some testing to show the effects of each in various combinations. (Update: more changes and tests.) Note that this is not the final mitigation work; compilers (i.e. gcc) are being updated to include workarounds for this, so new gcc -> new compiler in DragonFly -> new defenses. No silver bullet there, though.
One side effect of Meltdown/Spectre are CPU microcode (firmware) updates. For future needs: sysutils/devcpu-data is the port that has the updates for Intel, and cpucontrol(8) is the program you run on DragonFly to add them.
I haven’t used this myself, yet, so I can’t tell you how necessary an immediate update could be – but you will probably want to use it soon.
Update: Newer CPUs might require this sizing change.
I had to trim this down; there’s been a post-Christmas surge in material.

I’m a bit late posting it, but: BSDNow 227 covers Open, Free, and Net this week.
It’s turned off and on by the sysctl machdep.isolated_user_pmap – and defaults to on for Intel CPUs. Buildworld tests show about a 4-5% performance hit, but that’s only one form of activity, measured, so there will surely be other effects.
Note that Spectre is not mitigated by this commit series, and as I understand it, cannot be realistically fixed in software.
Update: Matthew Dillon posted a summary to users@.
Update 2: He told us so.
More user group news: Helsinki, Finland, has a new BSD User Group: HelBUG. First meeting is February 7th. There’s no mailing list/site that I know of, yet.
DragonFly has a donation page and a Paypal account. There’s no 501c3 benefit for U.S. residents to donate; DragonFly doesn’t exist as a non-profit. People have still been donating in smaller sums over time. It’s not enough to offset the colocation fees ($4k/year) plus the hardware there, but the money does get used for specific tasks. Matthew Dillon wrote a description of his upcoming plans: more storage, plus some interesting details on how much wear the existing SSD disks have sustained.
