What's New in OpenBSD 4.2?
blackbearnh writes "OpenBSD 4.2 was released today, and has a host of new features. O'Reilly's ONLamp site has a pretty thorough overview of the release. 'Even though security is still there, this release comes with some amazing performance improvements: basic benchmarks showed PF being twice as fast, a rewrite of the TLB shootdown code for i386 and amd64 cut the time to do a full package build by 20 percent (mostly because all the forks in configure scripts have become much cheaper), and the improved frequency scaling on MP systems can help save nearly 20 percent of battery power. And then the new features: FFS2, support for the Advanced Host Controller Interface, IP balancing in CARP, layer 7 manipulation with hoststated, Xenocara, and more!'"
Since the submitter didn't bother linking to their site (!!?), if you want to try out some of these amazing new features and improvements instead of just reading about them, you should head over to the OpenBSD 4.2 page and snag a copy!
My work here is dung.
I use OS X on my workstations, because I think it's the best *nix workstation at the moment, but I use Linux, exclusively on the server. I really need to try BSD. I really enjoy ports on OS X, so I'm sure I'd like it in BSD.
The only problem I run into on OS X is some of the GNU tools aren't there, and the BSD version of stuff like ls and such are different. But you can port install that stuff, so really that issue is mute. I think I'll fire up a virtual server and try out BSD
Remember, Theo de Raadt loves each and every one of you, he includes love in each copy of OpenBSD! Well, love or an incredible hatred of the x86 platform and everything not OpenBSD.

What's BSD?
This post climbed Mt. Washington.
Ah, that brings back memories of 4.2BSD, the first BSD with real Internet support.
(OpenBSD 4.2 seems somewhat less exciting to me.)
Christoph Egger did a OpenBSD Xen port (based on the NetBSD xen stuff) see: http://hg.recoil.org/openbsd-xen-sys.hg It looked pretty promising. It's too bad they aren't going to support that platform. I've got lots of customers who'd really like a OpenBSD option.
I've filed a bug report on this but at this point I'm not even sure its a bug... could be a hardware issue..
If anyone is running Adaptec SCSI 2940 controllers with more than one SCSI hard drive and it works then I'd like to know... if anyone is having problems I'd like to know.
The issue is that I have one 2940 fast narrow card and it won't boot... says there is no O/S. In the same machine... swap that card out to a 2940 fast wide and it boots just fine. Perhaps this is a firmware card issue. I have so far only tested these two cards... I plan to go get a handfull more.
Next issue. With the fast wide all seems 100%. Then I start an rsync from another machine and within seconds I get a kernel panic. There is a bug report here: http://paste.lisp.org/display/49908#1
Is OpenBSD bug report # 5616
I'm not at this point asking anyone to debug this. I want to know if others have a similar setup and it works.
This machine is a Pentium I, with two fast narrow SCSI disks and in this case an AHA 2940 FW card. There is nothing else on the bus.
O/S version was 4.1 and now I can try the new version. Since OpenBSD is such a great O/S I sure would like to get to the bottom of this without wasting people's time. If we have a problem we need to know about it and potentially fix it. If its an isolated issue then I need to know this so I can shelve the hardware if in fact it is flakey hardware.
Note: With that fast wide controller... dd if=/dev/sd1 of=/dev/sd1 bs=2048 will run 100% and never glitch at all. But try that rsync on the system.. kernel panics 100% of the time within seconds.
I know OpenBSD is renowned as a secure system, but it also is a good desktop OS. In fact, I bet it recognizes more devices than my Windoze Vista. I was pleasantly surprised the last time I tried out OpenBSD on my laptop. My only complaint is that the ports are not as comprehensive as FreeBSD. But then, maybe I should be a maintainer for one and stop complaining, lol.
One of the things that has put me of OpenBSD is the need to compile from source if you want to use the stable branch. I realise this is partially due to limited resources and priorities, but I would argue that this is probably one area where there is room for improvement.
In any case they have done a lot of good work. Copyleft vs OSS ideology disputes aside. ; )
One of the things I love about OpenBSD is pf. It blows away iptables. Not only in functionality, but in the syntax language as well. You don't have to have a cheat sheet for pf like iptables, which lessens the chances for mistakes IMHO. Iptables syntax is extremely painful to work with in comparison.
So have they included any sort of package auditing yet? Something along the lines of portaudit in freebsd? For those of us who don't enjoy upgrading just to upgrade, and don't want to have to monitor mailing lists to see everytime a package has an issue, is there any automated package auditing?
One thing I never really figured out with OpenBSD is why errata patches are handled the way they are. Why doesn't OpenBSD offer binary updates? For example, here are the instructions to fix errata entry 009 ("Fix possible heap overflow in file(1), aka CVE-2007-1536."):
Given that I installed from binary packages as do most users, and I might not even have a compiler installed, the startup cost of following those steps is fairly substantial. It seems like it would be easier for someone at OpenBSD to run those commands, see which files changed, wrap them up into a tarball, and distribute those - at least for the most popular architecture or two.
Now, I'm not saying they should do this or that they owe it to us end users to do it. I just mean that it'd be amazingly convenient with a seemingly minimal amount of extra work. Am I wrong about what would be involved?
Dewey, what part of this looks like authorities should be involved?

There is a new song, as far as I am concerned, that is one of the more exciting features in OpenBSD 4.2. :)
"Civis Europaeus sum!"
basic benchmarks showed PF being twice as fast, a rewrite of the TLB shootdown code for i386 and amd64 cut the time to do a full package build by 20 percent (mostly because all the forks in configure scripts have become much cheaper)
/. so this is to be expected, but this is getting ridiculous.

...the OpenBSD philosophy is security through openness. When you receive a security patch as source code, you can see exactly what is being done. If the patch were to include a binary image, verification would be slightly more difficult.
There have been binary patch projects (I used to use one at openbsd.org.mx), but since I have resigned myself to installing a compiler and the whole of the OS source code into /usr/src, I find the binary patches to be superfluous.
OpenBSD does cling to some of the other BSD behaviors in lieu of POSIX. Default use of the long-deprecated C-Shell and old-style "ps" behavior ("ps aux" rather than "ps -ef") come to mind.
Having everything in /usr/src is really the UNIX way from the days of old. It's a shame that we moved away from this practice.
I am thinking some of the optimizations to pf and the network stack are pretty cool but I think I will be waiting for sp1 when they have worked out all the bugs and security holes before I upgrade my machine.
thats right, I rarely use capitals. deal with it. but don't mistake my laziness for stupidity
All the popular distros have them! How about "Demonic Deadyet"?
That is all.
The only reason I clicked on this article is 'cos I really dig the red stylesheet for BSD news here. Reminds me of strawberries.
I assume BSD has other, more useful features though.
I posted this on another thread... I was thinking of a less ambition approach... just common driver bug handling layer.
I wonder if it is possible for all OSS software driver writers to coordinate their efforts and develop a common driver model for all OSS operating systems.
Personally I have written hardware drivers... many years ago I wrote in assembler video drivers for ega/vga cards. After months of digging and gobs of work my conclusion is this is a thankless job... but it is a critically important job and one that those who are involved with should take a great deal of pride in their contributions.
So I ask... is it feasible to create a common device driver layer so that problems solved for one OS can be solved for all?
And since this is all BSD licensed code you are free to take the code, put it in your proprietary "net security appliance" making any improvements of course without giving one single improvement back.
There are SO many 1U security "black boxes" that obviously rip off OpenBSD for 95% of their product it's just pathetic. I don't recall many of them touting that they used OpenBSD or ever hearing some of the "cool" features they SAY they have ever being contributed back to the main code repository for OpenBSD.
cite on the security hole in man? A little bit of googling couldn't turn it up. man has no special privileges and it doesn't listen on the network. How can it have a security problem?
As for GNU stuff bloatware -- You remind of "ed is the standard editor". Sheesh. bash uses a heck of a lot less memory than xterm, coming in at around 400k unshared.
The only problem I have ever had with OpenBSD was rustiness. I tend to have Linux on things that are close at hand and and I'm playing with regularly. I've used OpenBSD on boxes that are install-and-forget. I had a primary box for me at a colo running OpenBSD 2.9 until just this summer (a few days short of 6 years). I had to panic on the day of the OpenSSH vulnerability... and that was it. Just kept working. So, when I decided to replace it, I had to brush of on some of OpenBSDs uniquenesses from Linux.
Not that they're bad uniquenesses. Good ones mostly. And, I think the old saw still holds true. Linux is for people who don't like Windows. BSD is for people who actually love UNIX. I use both.
They deserve a bigger check than they gotten from me so far.

The purpose of the bug report is to see if its a problem with flakey hardware.
In order to track something like this down I'd have to set the machine up with a serial I/F to another machine and set it up on the net so that it can be properly debugged. I offered to do this. Theo declined. He simply said "no thanks".
I searched the OpenBSD archive of bug reports and found nothing related to the problem. Clearly there are problems however. Those cards work properly in other operating systems. The short of it is that if OpenBSD lacks driver support then I can't use it.
Hahaha, purely fucking tasteless joke but I laughed out loud. :)
