Long ago I worked in the kernel of a BSD which supported async (disk) I/O. The internals did use a kernel thread for queueing and reporting. There was one per process using AIO because it made life simpler: each page which was mentioned in AIO had to be pinned, and "blaming" that on the AIO thread was easy. similarly, there was "someone to talk to" when the I/O completed. Useful? It made architecting correct replacements for thread-using catastrophes -much- easier. Implement a work ...

Hi all , Today my openbsd server started to send some errors to syslog that i could not find anything about this error. symon: if(mtd0) failed (ioctl error) what does it mean ? Regards ismail

the workaround is to reduce the MTU, or for TCP you can use scrub max-mss (1220 is a safe value to clamp MSS to; this equates to MTU 1280, which all IPv6 hosts are required to handle). as for plans, well it would be useful, but I think it basically comes down to somebody needing it badly enough that they either do the work themselves, some firewalls *may* just be enforcing policy on the first fragment and letting the subsequent fragments through without checking them, in which case they ...

I have an IPv6 over IPv4 connection. I once had two, one using a hexago tunnel and the other I still have using a Hurricane Electric one. I have never had a problem connecting through OpenBSD with a pf firewall to native IPv6 sites like Google's v6 or the hosts on the /32 IPv6 netblock I maintain using an OpenBSD / OpenBGPd router. Maybe I'm just lucky. I'm a bit confused as to why packets need to be fragmented on IPv6 other than to play DDOS games. Nobody needs packets bigger than the ...

Are you in the wheel group? See permissions of /dev/drm0

According to radeon(4), my ATI Radeon Mobility 7500/M7 is supported by the driver but as far as I can tell DRI is not loading properly when I start X. X seems to work well enough besides 3D performance, which is dreadful. An incriminating bit seems to be here: ...

Hi everybody, I would like to install OpenBSD 4.6 on a Compaq AP550 Server with two HD SCSI. I burned the 'install46.iso' image, but the installation always freeze after the message: "rd0 fixed 3800 blocks". I tested the CD on my laptop and the installation goes ahead smoothly. I found several references to the same problem on the web on Dell and HP machines, but no one pointing to a specific problem. I read that it could be something related to the discs, therefore today I will try ...

I know that a filesystem in unix just exists wherever it exists (i.e. it's 'identity' is its mountpoint), but I find it extremely handy with ext* and FAT filesystems to be able to give every volume its own name. I was just living with not being able to do this on OpenBSD, just discovered dumpfs(8) and noticed a "volname" property snuck in at the end. It doesn't seem like newfs(8) or tunefs(8) let me set this at all, but (and you may find this vain) is there any secret tool that lets me edit ...

hi there, a couple of days ago, after seeing the cvs commit for initiating suspend upon closing the lid, i have asked to question how to revert this, as i fairly often close the lid but prefer no action taken. as my netbook dies a horrible death on wakeup (and possibly at suspend itself) the change was very counterproductive, me forgetting all the time i can't close the lid. so theo later committed that closing the lid does nothing so far. a sensible thing i think. but now if i press ...

On Thu, 10 Dec 2009 03:19:14 +0100 Kinda, look at changes to those drivers since the last hackathon, should have been clear from your ref to eeeeeeeeeepc... If you rip/comment out the relevant lines from acpibtn the event won't be registered by acpi and you should get your wished behaviour. Btw, to shutdown just type: 'sudo halt -p' that will even work with generic. Closing the lid on a running notebook is a bad idea, because a lot of heat will be capture under the closed screen that ...

Yup, it should definitely be more fun. :) Thanks for all the help. ~Corey

Hi list. I have OpenBSD 4.6 GENERIC on my Acer laptop and can't seem to get my NEC Aterm wl54ag pcmcia wfi card to work. The chipset is AR5212, which _should_ be supported by the ath driver. However, when I insert the card it isn't detected and dmesg spits out "cardslot0: cardbus support disabled". If I stick in a prism based card the wi driver picks it up without issue so the slot is good, and I tested the NEC card under linux, so its also good. I'm no OpenBSD expert, but perhaps the ath ...

It's an AMIBIOS from 2000, and its pretty rudimentary. I couldn't find anything related to CardBus.

On Wed, 09 Dec 2009 19:55:44 -0600 Ok, my bad. At the boot prompt: boot -c bsd disable apm enable acpi quit Sorry. - Robert

It's all good. Any other last minute ideas before I give -current a shot?

Okay, got the system back to booting after I RTFM'd boot(8)and boot_config(8). Sorry, for asking questions before checking the man pages, bad linux user habit.....

You can have this for free, along with the software!... http://www.openbsd.org/cgi-bin/man.cgi?query=pf.conf What a bargain.

Thanks for that, was unaware of that book. Just ordered my copy now :) Steph

I'm almost certain this one turned up as a relevant title in one of my safaribooks.com searches recently, so it's conceivable you could download or piece together a PDF from there.

Not sure about the other authors, but I remember Nazario from the FW-WIZ list and he knows his stuff very well. Its probably a pretty good book, aside from being 5 years old and so not being as current as the documentation and all that.

On Wed, Dec 9, 2009 at 12:03 PM, Daniel Gracia Garallar IMHO I hope OpenBSD doesn't use locks at all in the future taking FreeBSD's lesson, but does something what Dragonfly does - LWKT with message passing synchronisation. http://www.dcbsdcon.org/speakers/slides/luciani_dcbsdcon2009.pdf The fine-grained locking in FreeBSD is quite a crikey mess.

There was a recent FreeBSD vulnerability along those lines, see http://www.mail-archive.com/full-disclosure@lists.grok.org.uk/msg38274.html. Joachim

So in what cases does softraid degrade the mirror then, other than pulling the disk out? How is hardware mirror raid different? Thanks.

I must not be making myself clear. No, softraid can and will not detect that. Even if you know you only know that the data is bad; there are no other hints that can be deduced from that knowledge. This can happen when a drive returns corrupt data for whatever reason, be it hardware failure or a failed previous write etc. Let me repeat: No telling on fsck/OS; could be from silent data corruption to looking at a ddb prompt.

It isn't identical because softraid does not initialize raid 1 because it doesn't matter. So all written data is the same but areas where the Kind of. The short is that you can't guarantee this. Even if you detect that 2 areas that should have been the same but are not you You don't. This is where fsck and backups come in. Note: this whole story is different with RAID 5 & RAID 6.

There are pro and cons to both solutions. Pick what makes sense in your They read the data to make sure the disk is working. If one disk is failed they can rebuild that block from the remaining disk provided that the remaining disk isn't corrupt or broken too. They assume that the data that was read is accurate; if it isn't you are SOL. They either don't detect or ignore blocks that are different because they can not know which one is accurate (if any). Verify for RAID 1 is mostly ...

Agreed Bob but as a practical matter I won't be able to explain this problem to my 80 year old father-in-law. Unfortunately that's a requirement if I want to convince him to pay $10.00 more per month for the local CableTV internet service provider. Sadly the person most affected here is my mother-in-law who just wants her TiVo to work. Furthermore he won't even take the money from me. His thinking is that if the phone company can give him Internet Service for $35.00 / month then the ...
