The cpustop IPI is handled though an NMI, which means it could interrupt a CPU in any moment, even while holding a spinlock, violating one well known FreeBSD rule. That means that the cpu can stop itself while the thread was holding the sched lock spinlock and not releasing it (there is no way, modulo highly hackish, to fix that). In the while hardclock() wants to schedule something else to run and got stuck on the thread lock. Ideal fix would involve not using a NMI for serving the cpustop while having a cheap way (not making the common path too hard) to tell hardclock() to avoid scheduling while cpustop is in flight.

> I would say in this case you're *not* giving the entire disk to the > pool, you're giving ZFS a geom that's one sector smaller than the disk. > ZFS never sees or can touch the glabel metadata. Is ZFS happy if the size of it's disc changes underneath it ? I have expanded a zpool a couple of times simply by changing the size of the partition and rebooting the machine - it comes up with the new amount of free space fine. Never tried it the other way though. The reason I mention it is that someone suggested glabeling a drive in an existing pool and using replace to swap it over. Which should be good I guess unless the last sector was in use. ZFS spreads stuff all over the disc as I unserdtand it though, so that might not be a good assumption, even on a fairly empty filesystem. -pete. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
sshd GSSAPIAuthentication broken after 8.0-BETA1 upgrade
I source upgraded a (test) server here (i386) from 7.2-RELEASE-p2 to 8.0-BETA1 this morning. I use GSSAPI as the primary authentication method for sshd on that server. After the upgrade GSSAPI authentication stopped working and I can't get enough information to figure out why. Perhaps the newer version of Heimdal behaves differently? Perhaps the newer version of sshd behaves differently? If I run sshd with debug "-ddd" I see the following: debug1: attempt 1 failures 0 debug2: input_userauth_request: try method gssapi-with-mic debug3: mm_request_send entering: type 37 debug3: mm_request_receive_expect entering: type 38 debug3: mm_request_receive entering debug3: monitor_read: checking request 37 debug3: mm_request_send entering: type 38 debug3: mm_request_receive entering Postponed gssapi-with-mic for john from 192.0.2.123 port 57225 ssh2 debug3: mm_request_send entering: type 39 debug3: mm_request_receive_expect entering: type 40 debug3: mm_request_receive entering debug3: monitor_read: checking request 39 debug1: Received some client credentials debug3: mm_request_send entering: type 40 debug3: mm_request_receive entering debug3: mm_request_send entering: type 43 debug3: mm_request_receive_expect entering: type 44 debug3: mm_request_receive entering debug3: monitor_read: checking request 43 debug3: mm_request_send entering: type 44 debug3: mm_request_receive entering GSSAPI MIC check failed On the client side (with ssh -vvv) I see: debug3: preferred gssapi-with-mic,publickey,keyboard-interactive,password debug3: authmethod_lookup gssapi-with-mic debug3: remaining preferred: publickey,keyboard-interactive,password debug3: authmethod_is_enabled gssapi-with-mic debug1: Next authentication method: gssapi-with-mic debug2: we sent a gssapi-with-mic packet, wait for reply debug1: Delegating credentials debug1: Delegating credentials debug1: Authentications that can continue: publickey,gssapi-with-mic,keyboard-interactive debug2: we did not send a packet, disable method Does anybody know of changes between existing STABLE releases and 8.0 which would cause this behaviour - and how to accommodate it? Do any strange Kerberos things need to be done as part of the upgrade? The client still happily authenticates via GSSAPI to sshd on our other 7.2-RELEASE servers. Subsequent authentication methods succeed on the 8.0-BETA1 sshd server, it's just GSSAPI that isn't working. Thanks. -- John Marshall pgprtYGf1BSlH.pgp Description: PGP signature

Ken Smith wrote: The amd64 and i386 architectures include a file named: 8.0-BETA1--memstick.img If you copy that to a USB memory stick newer machines should be able to boot from it and use it to install from. Note that you need to overwrite the contents of the memory stick completely, not copy it into an existing filesystem on the memory stick. Exactly how you do that depends on your machine but just to give you an example this works on the machine I tested it with: dd if=8.0-BETA1-amd64-memstick.img of=/dev/da0 bs=10240 conv=sync Be careful if you have SCSI drives, more USB disks than just the memory stick, etc - make sure /dev/da0 (or whatever you use) is the memory stick. Using this image for livefs based rescue mode is known to not work, that is one of the things still being worked on. Unfortunately my biggest mem stick has only 512MB. So I tried to dd to an usb drive. (Will get a bigger stick tomorrow) I was successful in installing the image, although, a few packages did not install. I did a kern developer package. I guess the packages are missing on the .img? Right now I'm installing the other things via net. Is this method equal to an usb stick install at all? Below the top of dmesg.

ZFS: zpool scrub lockup
Hello, I don't know whether this is the right list; maybe freebsd-fs is more appropriate. So please redirect me there if this isn't the right place. My system (i386, Athlon XP) locks hard when scrubbing a certain pool. It has been doing this for at least a couple of months now. For this reason I upgraded to 7.2-STABLE recently as this had the latest ZFS bits, but this doesn't help. It even makes the problem worse: in previous versions I just hit the reset button and forgot about it, but now it "remembers" that it was scrubbing (I presume) and tries to resume at the exact same place, locking up again. This means I haven't been able to mount these ZFS volumes successfully: the moment I do a /etc/rc.d/zfs start from single user mode (I have my /, /var and /usr on UFS) it locks up in a couple of seconds. And by locks up I really mean locks up. No panic, nothing. Pressing the reset button on the chassis is the only way to reboot. Details about my system: Athlon XP 2400+ Asus K7V-880 (VIA chipset; 2 IDE, 2 SATA ports) 2 GB RAM Promise Ultra133-TX2 (2 port IDE controller) Promise SATA150 4 port SATA controller Promise SATA300 4 port SATA controller 4 Maxtor 300 GB IDE disks 1 Maxtor 300 GB SATA disk 1 WD 320 GB SATA disk 6 Samsung 1 TB SATA disks The Samsung disks form the pool I'm having trouble with. They are connected to the Promise controllers. Does anyone know how I can debug this? I'm not even sure whether it is a software or a hardware problem. Any help is greatly appreciated!

8.0-BETA1 Source Upgrade breaks NTP configuration
Yesterday I source-upgraded a 7.2-RELEASE-p2 test i386 server to 8.0-BETA1. I have just discovered that it broke that server's NTP service. PROBLEM 1 - Existing /etc/ntp.conf overwritten For source upgrades I run "mergemaster -iCPU" and it has served me well until now. Mergemaster appeared to run "as normal" for this upgrade, prompting me for decisions on how to deal with the handful of usual files. It didn't tell me that it had decided to overwrite my existing /etc/ntp.conf with the new default version from the source tree! (OK, perhaps it told me in the big, long list at the end but it didn't prompt me to supersede my existing file). Looking at the mergemaster(8) man page, I can't see how the options I use would have resulted in my existing /etc/ntp.conf being overwritten with the version from the source tree - but obviously there is a woops factor there, either with me or mergemaster. Digging deeper, it looks like it may be due to the fact that this is a new supplied file and an entry for /etc/ntp.conf didn't exist in /var/db/mergemaster.mtree from the previous (7.2-RELEASE) run. How should this be handled? PROBLEM 2 - Default ntp.conf uses LOCAL clock So, having had the FreeBSD upgrade magically re-configure my NTP server (no, I wasn't prompted to overwrite ntp.conf), I find that my NTP server is now synchronizing with it's own (potentially wrong) local system clock! Our firewall is configured to allow NTP traffic between our internal NTP servers and specific upstream NTP servers. The default configuration file specifies different servers which we don't use, so this NTP server couldn't "see" them. The new default configuration file includes "127.127.1.0" as a configured server. Because we could see no "real" NTP servers, we synchronized with our local system clock. That means that we think we are synchronized to a reliable upstream source. Rather than losing synch and discovering the problem, we think we are synchronized to a reliable source and we and our clients drift away from reality in blissful ignorance. Surely this violates POLA! Could we *please* at least comment out the LOCAL server config in the supplied ntp.conf? Personally I would rather see it removed. It is one thing to tell people where the gun is if they want to shoot themselves in the foot; it's another thing to load it and fire it for them. I think it is good to have a default ntp.conf to help new users get started. I think it is a bad thing to include potentially dangerous elements in that configuration which could cause grief to a novice NTP administrator. If the default configuration provides scope for such surprises, they will (rightly) blame FreeBSD. -- John Marshall pgps3TTLn0uRN.pgp Description: PGP signature

I guess the packages are > missing on the .img? Correct, no packages with BETA1. It's probably the documentation packages it went looking for and couldn't find. I'll be providing at least the docs packages with BETA2. Not sure if I'll start trying to provide a larger set of packages for the DVD or wait for BETA3 for that (leaning towards waiting at the moment). -- Ken Smith - From there to here, from here to | kensm...@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel | signature.asc Description: This is a digitally signed message part

Then I inserted the new drive and initiated a scan for it. Apparently ZFS doesn't realize when a resilver is partially done because it resilvered in a matter of seconds at this point. I then did a scrub which found several million checksum errors but successfully corrected the pool without any vdev I/O failure errors.
