tgardnerogasawara, I've rebased to -rc5. would you like me to push it, or are you already in the middle of it ?15:20
ogasawaratgardner: jinx, I just pushed it15:20

bjftgardner, http://www.spinics.net/lists/mm-commits/msg83181.html This indicates that the patch I have requested is the one intended to fix CVE-2011-101715:38
ubot2bjf: Heap-based buffer overflow in the ldm_frag_add function in fs/partitions/ldm.c in the Linux kernel 2.6.37.2 and earlier might allow local users to gain privileges or obtain sensitive information via a crafted LDM partition table. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1017)15:38
tgardnerbjf, you've read my email response from this morning?15:42
tgardnerI think we need both patches15:43
bjftgardner, ok, i didn't read it clearly, i thought you were proposing yours, instead of mine, but i see that is no the case15:44
bjftgardner, and i agree that we probably need both15:45
tgardnerbjf, ok, erply on email and I'll apply both. same for lucid and hardy?15:46

apwsmb, what was the number for the t1.micro bug16:10
smbapw, https://bugs.launchpad.net/ubuntu/+source/linux-ec2/+bug/63448716:10
ubot2Launchpad bug 634487 in linux "t1.micro instance hangs when installing java" [High,Confirmed]16:10
=== fairuz is now known as fairuz-away
=== fairuz-away is now known as fairuz_
smbapw, That would still be present. Beside of not really understanding the update concept (if I do any update/upgrade with centos 5.0, I ended up being on centos 5.5). Centos 5.0 had locally the disadvantage of locking up and not working well with pv-grub.16:22
smbAnd having an domU with 5.5 plus xen 3.0.4, I never see this problem. Of course I have no clue what exactly ec2 has in dom016:24
apwsmb, is it accurate to say that the issue, is only during install of java on t1.micro, ie it will work in that size once installed ?16:29
smbapw, I think that was some work-around mentioned. To do the installation and then resize the instance. But I am not completely sure whether nothing would happen later on16:30
apwsmb, thats close enough for my purposes16:31
smbapw, One sort of interesting point is that at least for Natty it only happens on i386 because on 64bit some post.install step that actually causes the problem is not executed.16:32
JFotime for some lunch, bbiab16:50
tgardnersconklin, bjf, jj-afk, ogasawara, apw, smb, sforshee, ppisati, herton: there are still a couple of unreviewed patches on the k-t list: https://lists.ubuntu.com/archives/kernel-team/2011-April/015340.html , https://lists.ubuntu.com/archives/kernel-team/2011-April/015371.html. Please take a moment so we can wrap them up.16:50

hallynsmb: apw: do you know if the fix to bug 747090 is supposed to be shipped in any natty kernel?18:17
ubot2Launchpad bug 747090 in linux "wrong return address sometimes pushed for INT in kvm (not qemu)" [High,Fix committed] https://launchpad.net/bugs/74709018:17
hallynI ask bc I have completely unscientific 'evidence' (read, i can't explain it any other way) that it also fixes bug 77122718:18
ubot2Launchpad bug 771227 in libvirt "Domain save/restore does not work (kvm)" [Medium,Confirmed] https://launchpad.net/bugs/77122718:18
smbhallyn, Hm, not sure from my memory. I thought this was one fix which may have gone in a rebuild if that was to happen...18:19
ogasawarathe fix is going out in the first kernel SRU, we decided not to do the rebuild18:20
smbogasawara, Thanks, I was about to reach the same conclusion from git in a bit. :)18:20
smbhallyn, So if the question was whether there is any kernel or was it whether there is a released kernel?18:22
hallynsmb: ogasawara: ok, thanks.18:22
hallynit's not in natty-proposed yet right?18:22
hallyn(I've seen some things go up)18:23
hallynto my surprise)18:23
hallynI'll just ask him to try the debs attached to the bug18:23
smbThere might be something in pre-poposed of kernel-ppa18:23
hallynsmb: thx18:25
smbDon't think there should be any natty-proposed until the royal wedding is over, err we have released18:25
=== hallyn is now known as hallyn_afk
tgardnerhallyn_afk, you can always get tip of master-next for Natty from https://launchpad.net/~kernel-ppa/+archive/pre-proposed?field.series_filter=natty18:26
bjfogasawara, to have the first natty ready for the next SRU cycle, we want to have it built and ready in the ppa by Friday so we can have it copied out18:26
ogasawarabjf: ok, I assume you and sconklin are handling that?18:27
bjfogasawara, probably18:27
tgardnerbjf, did you note there are 106 2.6.35.y updates in the pipe?18:28
bjftgardner, i noticed, yes :-)18:28
=== skaet is now known as skaet_
tgardnerogasawara, I've got your oneiric kernel on my emerald up to 325+ load average using 'stress -t 3600 -c ${NP} -i ${NP} -m ${NP} -d ${NP}' while doing a build. I can't get it to swap much though. Looks like its flushed 384k worth to swap and left it at that. NP=8018:48
ogasawaratgardner: and that's the latest -rc5 rebase?18:57
bjfogasawara, i just did a 'maint-startnewrelease' on natty master and it failed18:57
bjfII: linux-image-2.6.38-8-powerpc64-smp_2.6.38-8.42_ppc64.deb18:57
bjfII: Downloading to kernel.ubuntu.com ... FAILED!18:57
bjfogasawara, does that make sense ?18:58
ogasawarabjf: hrm, I don't use the maint startnewrelease script, I've always done it manually eg fdr startnewrelease etc18:58
tgardnerogasawara, yes, -rc518:59
bjfogasawara, how do you pull down the abi files? do you just run maint-getabis ?19:00
ogasawarabjf: debian/scripts/misc/getabis19:01
ogasawarabjf: and I run that on zinc since it's faster19:01
ogasawarabjf: then I'll copy the abi files to my local dev box19:02
tgardnerogasawara, which is pretty much what I do as well19:02
bjfmaint-startnewrelease does it all in one shot and is pretty nice19:02
bjfi thought we were all doing things consistently, guess not19:03
tgardnersome of us are still old school19:04
* tgardner --> lunch19:06
ogasawarabjf: I believe the ppc64 stuff is not officially supported.  apw put the config stuff in our tree for misc testing.19:09
ogasawarabjf: so the maint-startnewrelease scripts should probably ignore it for now19:10
bjfogasawara, i did it your way and it worked, so there must be a bug in that script19:10
bjfogasawara, i'm kind of confused now why maint-startnewrelease doesn't just run debian/scripts/misc/getabis and fdr startnewrelease, but whatever19:19
ogasawarabjf: no idea either19:20
ogasawarabjf: I can't remember if dapper is different when starting the new release, so maybe it handles that too?19:21
smbogasawara, bjf I think I had been adding quirks for dapper in the past19:26
smbBut not sure whether something broke in between19:27
bjfsmb, i've been using it for everything up til now, but it doesn't work for natty, i've not dug into it to see why19:27
smbbjf, Oh, that is likely to be19:28
smbThere can be things that are sort of declared in the controls but not really built19:28
smbThen some ignores have to be defined19:28

Anpheus__Does anyone know why Ubuntu 10.10 Server's minimal virtual install (-virtual kernel) does not contain the Hyper-V guest modules, if it is possible to restore those to that kernel, and most importantly; is this rectified in the next release?19:41
Anpheus__Someone from #ubuntu-server said they checked their 11.04 pre-release on EC2, installed with the -virtual kernel, and there are no Hyper-V kernel modules.19:47
Anpheus__There *should* be, because the hv_* modules are *only* useful in a virtual machine.19:48
=== arun__ is now known as arun_
tgardnerAnpheus__, its not in the -virtual image because its a staging driver.19:52
Anpheus__... Go on?19:52
Anpheus__I don't know what that means, or why that would be relevant.19:54
tgardnerAnpheus__, staging drivers are typically in a state of development, have lots of problems, and as such, we are not really interested in supporting them.19:54
Anpheus__And?19:54
Anpheus__There's a ton of stuff in Ubuntu Server, applications, drivers, kernel modules, that is unsupported by Canonical, if that's who you meant by "we".19:55
Anpheus__You have to manually configure those modules to be enabled, so I don't see the issue.19:56
tgardnerAnpheus__, the virtual image was intended to be relatively small, so we had to make decisions about what modules to include. staging modules didn't make the cut.19:57
Anpheus__it looks like the entire directory is less than 1MB19:58
Anpheus__Yep, all five of the modules are just about 256KB uncompressed.19:59
Anpheus__Or "KiB" if you prefer.19:59
tgardnerAnpheus__, use the server image.19:59
* jjohansen -> lunch20:00
Anpheus__I did, but I'm wondering why the virtual image, designed to run on VMs, doesn't contain five drivers that are *only* useful on a Redmond based company's hypervisor.20:00
