BenChey02:54
fabbionehey BenC 02:55
fabbioneBenC: how is it going?=02:55
BenCpretty good02:55
BenCfabbione: did any of the other security patches in your 2.6.10 upload have to do with 2.6.12?02:55
fabbioneBenC: we have one or two patches we need to portfoward from .10 to .1202:56
fabbioneBenC: i was planning to do it tomorrow02:56
BenCcan you send them to me?02:56
BenCI can get to them today02:56
fabbionethere is the hyperthreading patch (it's already in the archive)02:57
fabbioneand we need to check CAN-2005-191302:57
fabbionethe hyperthreading one is a very old CAN02:57
BenCalready in the 2.6.12 archive?02:57
fabbioneno.. it's in .10 only02:57
fabbioneand we need to portforward it to .1202:57
fabbionei did recheck all the security stuff while i was doing .1002:57
fabbioneand we miss that one in .1202:57
fabbioneand need to check the one for 191302:58
fabbioneit was in .10 package for long time, but never applied02:58
fabbionedon't ask me why :) i didn't do that release02:58
fabbioneso you can just grab the .10 sources from the archive02:58
fabbioneand you will get all of them02:58
fabbionein any case the ht is important02:58
BenCok, I'll take care of that today for 2.6.1202:58
fabbioneperfect02:58
fabbioneBenC: you probably recall that hw bug in p4 + ht processors02:59
fabbionewhen i started .12 i did purge that patch, because i was pretty sure upstream did fix it02:59
fabbioneyesterday it did pop to my mind to check it again02:59

BenCfabbione: that ht patch is really security related?03:29
BenCmaybe I'm looking at the wrong patch03:29
BenCht.dpatch, security related, ok03:30
BenCis ht insecure?03:30
MithrandirBenC: it appears so, yes.  You can get leakage of data from one process to another.03:30
BenCthere's no workaround for it other than disabling it?03:31
MithrandirI think it's a hardware problem, so no03:36

BenCfabbione? 03:50
dilingerBenC, fabbione: so, now that i've finally got an internet connection, i'm going to set up the sunfire and offer debian/ubuntu to use it as a buildd04:31
dilingerBenC: this is the machine that has the silo-booting-from-iso9660 problem, btw04:31
dilingerBenC: so if you get bored and feel like figuring out what's up w/ it, i can hook up a serial console and let you play04:32
BenCdilinger: I'd be interested04:40
BenCif I ever find time04:40
BenCthat UltraIII boot from cd problem has been haunting me for awhile04:41
dilingeri'll set it up over the weekend04:41
BenCmainly because I don't have the hw to reproduce it :)04:41
BenCdoes that system have LOM?04:42
dilingeryea, i remember you saying that, which is why i offered04:42
dilingeri believe so, although i've not played w/ it04:42
BenCif you can set that up (telnet or serial) that would be best04:43
BenCI'm sure I'm going to need a lot of hard power cycles, and I don't want to bug you every 10 minutes :)04:43
dilingeri assume you'll need me to burn cds anyways04:44
BenCah, true, didn't think about that04:44
BenCdoes the box have a cd burner in it?04:45
BenCthen I could boot to the system and do my own04:45
dilingerno, but the box that's hooked up to its serial does04:45
BenCdoesn't get around the need for you to be at my beck and call though04:45
dilingeri figured i'd just give you an account on there, w/ access to serial and the burner04:45
BenCcan you put a cdr capable drive in it? just IDE for the cd, right?04:46
dilingertrue, but it's in my apt, so it won't be a problem04:46
dilingeri believe it's ide04:46
BenCI work weird hours when I do off-time stuff though04:46
jbaileyReminds me that I should ask the grub sparc guy how it's going.  He had module and kernel loading working, but I don't think he actually had it booting the kernel.05:00
jbaileyBut he did have it coming up and loading the grub filesystem modules and such.05:01
dilingerhm05:01
BenCjbailey: wow, that'd be a nice improvement05:02
dilingerBenC: what do you suppose would happen if you attempted to boot off an iso9660 image that wasn't on a cdrom?05:02
BenCdilinger: not sure that's possible05:02
BenCopenboot has to think it's a cdrom05:02
BenCand first-isofs.b has to actually be on a cdrom05:03
dilingerok05:03
BenCwell, it atleast assumes such things when using firmware calls05:03
