| Sarvatt | well rtg wont be around till monday to bug IS to fix it :) | 08:11 |

| dileks_ | hi | 08:27 |
| === dileks_ is now known as dileks | ||
| dileks | apw: hi. you sent two patches as a replacement to "overlayfs: apply device cgroup and security permissions to overlay files". whats the status of them? | 08:35 |
| apw | dileks, oh yeah, hmm there was a response wasn't there and i needed to update the first very very slightly | 08:36 |
| apw | dileks, though they were simply nits in terms of functionality they were fine | 08:37 |
| * apw is trying to work out what happened to overlayfs recently right now, maintainer is not as clear in response as one might hope | 08:37 | |
| * dileks checks inbox | 08:37 | |
| apw | dileks, no as in there was a response back when i submitted them the very first time | 08:38 |
| dileks | [PATCH 1/2] inode_only_permission: export inode level permissions checks | 08:38 |
| apw | yeah that one has a very minor change on it, which i've yet to do | 08:38 |
| dileks | miklos: "IS_IMMUTABLE() is per-inode. So I think only the IS_RDONLY() check | 08:39 |
| dileks | needs to be left out." | 08:39 |
| dileks | OK, I see | 08:39 |
| apw | dileks, indeed but the patches are functional, a bigger worry is getting this heap to work properly again | 08:39 |
| dileks | would you be so kind :-) | 08:39 |
| dileks | you know any news about union-mounts? I just remember an email from al viro - typically with lots of f-words/s-words to wait for it, when miklos tried to get overlayfs upstream. | 08:41 |
| apw | the upstream position is not easy to fathom. al is right overlayfs is not semantically complete nor will it likely ever be. whether that is an issue i am unsure in the long run, and as they won't let it in its hard to work that out in the real world. | 08:43 |
| apw | our experience is some of the issues are invisible, one or two are niggling, whether those are addressible without distroying overlayfs' simplicity i am unsure | 08:44 |
| dileks | agreed, overlayfs is a "simple" approach. it fits my needs to run a linux live-system. openwrt uses overlayfs since early stage, though. | 08:46 |
| apw | yep | 08:49 |
| dileks | apw: please CC on updated ovl-patches, thanks | 09:04 |
| henrix | apw: hi! any updates on the buildd machines? | 09:20 |
| apw | henrix, nothing as yet | 09:25 |
| henrix | apw: cool! and are there any other build boxes available? | 09:25 |
| apw | henrix, see pm | 09:25 |
| henrix | apw: thanks, i'll try that | 09:25 |
| Kano | hi, i miss 3.3.4, 3.0.30, 3.4-rc5 mainline | 09:37 |
| Kano | apw: something broken with mainline builds? | 09:37 |
| apw | Kano, the machine which does them is down | 09:38 |
| Kano | why? | 09:38 |
| apw | broken | 09:39 |
| apw | and it being release week we have other priorities | 09:39 |
| Kano | well this week is after release. do you have got efi test systems? | 09:40 |
| apw | are we going to argue semenatics on an english phrase here? is are busy, its not fixed | 09:41 |
| apw | it is an unimportant system which only produces test kernels which we can live without | 09:41 |
| apw | personally no i don't have efi, i am sure someone does, but not me | 09:41 |
| Kano | ah, maybe you should request a new board then | 09:42 |
| Kano | that script contains the minimal patches needed to get efi stub 64 bit working. there are extra patches in mainline not mentioned you most likely need for 32 bit | 09:43 |
| Kano | http://kanotix.com/files/fix/efi/linux-3.2-efi-stub-patcher.sh | 09:43 |
| Kano | 32 bit efi are basically only old intel macs | 09:44 |
| Kano | when i boot 32 bit via efi then i have got no acpi support, which means only 1 core / no speedstep and no poweroff on shutdown | 09:46 |
| Kano | nothing i like to test ;) | 09:46 |
| Kano | but efi stub support is really cool. you can directly add it as entry. no grub needed | 09:47 |
| Kano | you need rdev, thats not in current packages however as scripting efi shell (then even with initrd support) does not really gain speed | 09:48 |
| * ppisati -> reboot | 09:56 | |
| * ppisati -> brb | 10:39 | |
| * ppisati -> lunch | 11:27 | |
| apw | ogasawara, just updated overlayfs back to the upstream version, and forward ported it, it passes my touch testing (and I mean light touch) so I have renabled it in quantal | 11:36 |
| dileks | apw: cool | 12:06 |
| * dileks checks ubuntu-quantal.git#master-next | 12:06 | |
| apw | dileks, i am putting an email together now with a clean upstream stack too | 12:06 |
| apw | dileks, let me know if it works more than a simple touch test ... perhaps its still broke | 12:06 |
| dileks | apw: so my "patches" helped you a bit | 12:06 |
| apw | dileks, actually as i was starting from a cleaned up base i suspect i reinvented the wheel some | 12:07 |
| apw | dileks, i didn't see your email till i was looking for the upstream thread for email addresses | 12:07 |
| dileks | OK. looks like my missing include and touch_atime() fixes were OK | 12:09 |
| apw | dileks, very likely, it was pretty menchanical | 12:09 |
| apw | dileks, the real difference is you were starting from the backported version we had in precise (which leann rolled forward) and i started from he non-backported version | 12:10 |
| * apw bets you were dumping in statfs (without looking at your trace) as that is waht it did before I backported it | 12:10 | |
| tgardner | apw, maybe you should rebase against -rc5 while you're at it. 'UBUNTU: SAUCE: add option to hand off all kernel parameters to init' has some conflicts | 12:10 |
| dileks | I am no fs-expert :-) thus d_make_root() transition was not that clear to me. but seeing yours, I understand a bit better | 12:10 |
| dileks | apw: thanks | 12:10 |
| apw | dileks, yeah they made the new interface harder to abuse, but not easy to use | 12:11 |
| dileks | I will check in a few minutes. ready-built git branch available | 12:11 |
| dileks | is -rc5 the new base for quantal? | 12:12 |
| apw | dileks, it built and i was able to do some manual testing with wahts on master-next right now | 12:12 |
| apw | dileks, its -rc4 right now, i am sure leann will be on that rebase soon | 12:12 |
| dileks | I talked with jordi pojol this weekend | 12:12 |
| apw | dileks, i am more interested in getting the thing compiling for the instant | 12:12 |
| dileks | he has some testcase scripts | 12:13 |
| apw | dileks, sweet, if you have anything do email it over so we can think about getting it in our tests | 12:13 |
| dileks | his test06 for example IIRC requires to loosen "fs: limit filesystem stacking depth" | 12:13 |
| dileks | http://livenet.selfip.com/ftp/debian/overlayfs/test/ | 12:14 |
| dileks | I have a bit polished up test06 | 12:14 |

| dileks | 0001-fs-Increase-limit-filesystem-stacking-depth-to-3.patch: http://paste.ubuntu.com/957369/ | 12:16 |
| dileks | apw: miklos remembers me ibm with os/2 | 12:17 |
| dileks | at the end ibm dropped lightyears-ahead os/2 in favour of win9x | 12:18 |
| apw | m$ wins sometimes | 12:24 |
| dileks | apw: /o\ | 12:32 |
| dileks | no crash no call-trace with your d_make_root patch | 12:32 |
| apw | dileks, very good ... | 12:32 |
| apw | dileks, i am pretty sure it would have been a statfs issue, they changed the interface 3.2 -> 3.4 and i had to undo that in the backport | 12:33 |
| dileks | OK | 12:33 |
| dileks | I took -rc5 as base. applied openwrts ovl-patch. and on top of that my 3 patches | 12:33 |
| apw | dileks, if it works well then this will be earliest we have had a working union mount | 12:34 |
| dileks | hmm, I must check log-file in tmp-dir | 12:34 |
| dileks | you wanna have TEST-3.4.0-rc5-ovl-1-generic-iE0 as a tarball for inspection? | 12:35 |
| dileks | testcase log-file: http://paste.ubuntu.com/957389/ | 12:36 |

| apw | dileks, sure email it over ... i assume that that logfile is a positive thing | 12:36 |

| apw | dileks, ahh ... makes sense | 12:40 |
| apw | dileks, you want me to drop that on top and make you a binary ? | 12:41 |
| dileks | jordi has thrown away that fs stack limitation patch | 12:41 |
| dileks | apw: feel free | 12:41 |
| dileks | jordi has some more patches, which were not sent to miklos | 12:42 |
| apw | dileks, for overlayfs ? if so i'd like to see 'em | 12:42 |
| dileks | http://livenet.selfip.com/ftp/debian/overlayfs/ | 12:43 |
| dileks | overlayfs-v12-2011Dec21-for Linux 3_3.tar.xz | 12:43 |
| dileks | I have repacked that un-U*ix-alike name tarball with a proper commented series file | 12:44 |
| apw | dileks, will have a look at 'em and see what we can do | 12:45 |
| dileks | series: http://paste.ubuntu.com/957405/ | 12:45 |
| apw | dileks, miklos has not been very responsive in my experience, if we can help ourselves then all to the better | 12:46 |
| dileks | from my inbox "I am pushing it out for perusal as people are asking me about it. This | 12:47 |
| dileks | includes an updated permissions fix." | 12:47 |
| dileks | what does that mean - those two pending patches? | 12:48 |
| apw | yes, its those two, but updated a third time i will get the whole stack I am carrying out to him shortly as email patches | 12:48 |
| apw | need to keep banging on them | 12:49 |
| dileks | thank you very much for all your efforts! | 12:50 |
| dileks | shall I send you my overlayfs stuff directly? | 12:50 |
| ogasawara | tgardner: any idea when we'll have gomeisa or tangerine back? | 13:19 |
| tgardner | ogasawara, apw started an RT ticket. they think it muight be networking issues. no ETA as yet | 13:19 |
| tgardner | ogasawara, tyler is still online | 13:20 |
| ogasawara | tgardner: any quantal chroots on it by chance? | 13:20 |
| tgardner | ogasawara, not yet. lemme see if it'll install on lucid | 13:20 |
| apw | ogasawara, i am building in precise chroots still, though they do exist so if you get an updated debootstrap it should be possible | 13:21 |
| ogasawara | apw: thanks for doing the overlayfs bits by the way | 13:23 |
| ogasawara | apw: I wanna rebase to rc5, test builds etc, and then get our first upload in | 13:24 |
| tgardner | ogasawara, I sucked down the precise debootstrap backport and installed it on tyler. the quantal amd64 chroot seems to be installing OK. | 13:24 |
| apw | ogasawara, i hear that it may clash on the init parameters bits, yell if you want me to poke | 13:24 |
| ogasawara | apw: will do | 13:24 |
| apw | tgardner, is kteam tools updated ? | 13:24 |
| tgardner | apw, for quantal ? | 13:24 |
| apw | for the chroot builds for quantal yes | 13:25 |
| tgardner | apw, yep | 13:25 |
| tgardner | apw, I had it built and tested on tangerine saturday morning before it went away | 13:25 |
| apw | tgardner, cool i'll give it a whirl here as my build box is spinning anyhow | 13:27 |
| tgardner | apw, it'll be a few mins until tyler is installed. the pipe from taipei to London is quite narrow | 13:28 |
| apw | tgardner, yeah it is indeed. /me spins up some chroots here for comparison | 13:28 |
| tgardner | apw, you'll need http://archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/debootstrap_1.0.40~precise1_all.deb | 13:29 |
| apw | tgardner, i just added the symlink, its always just one new symlink | 13:29 |
| tgardner | apw, indeed, its a simple patch | 13:30 |
| * apw watches chroots poop out | 13:31 | |
| apw | all looking good so far | 13:31 |
| === yofel_ is now known as yofel | ||
| apw | dileks, i think the concern over overlayfs as a module is fixed by the replacement security patches, as they export an all new interface for that purpose | 13:46 |
| dileks | OK | 13:46 |
| apw | ogasawara, https://blueprints.launchpad.net/ubuntu/+spec/security-q-kernel-backports | 13:52 |
| ogasawara | apw: yep, just saw it | 13:53 |
| dileks | apw: I answered your email and attached testcase-script plus the mentioned patch to run testcase successfully | 13:55 |
| * henrix will be back in ~30 mins | 14:05 | |
| * dileks runs a new kernel build with apws ovl patches + limit-fs-stack-depth=3 | 14:13 | |
| ogasawara | tgardner: don't suppose I could get ubuntu-quantal.git added to tyler's usr3/ubuntu | 14:23 |
| tgardner | ogasawara, can do | 14:23 |
| tgardner | ogasawara, looks like amd64 chroot is ready | 14:23 |
| ogasawara | tgardner: I'm gonna give it a spin | 14:24 |
| tgardner | ogasawara, quantal cloned | 14:29 |
| ogasawara | tgardner: thanks | 14:29 |

| spotter | http://marc.info/?l=linux-raid&m=133576777720867&w=2 | 15:24 |
| spotter | could be a major major data loss bug | 15:24 |

| * apw looks at spotter's issue | 15:26 | |
| bjf | jjohansen: ignore my request | 15:26 |
| spotter | apw, dont know if its an issue, just know that the it might be, and could be a major data loss issue | 15:27 |
| spotter | seems to be recoverable if one knows what they are doing, but easy to destroy one's data in the process as well | 15:27 |
| apw | spotter, the commit is in our kernel (the bad one) via upstream stable | 15:27 |
| spotter | ok, so that's bad | 15:27 |
| spotter | can follow up with them to figure out how bad | 15:27 |
| spotter | but think it almost destroyed my raid5 | 15:28 |
| apw | bjf, ^^ seems we have the first commit via stable and not yet the fix via stable, we probabally want to close that circle | 15:28 |
| bjf | apw, yes, saw that | 15:29 |
| apw | spotter, if i am reading this right you'd have to have a failure on the personality load as well, so i am not sure its going to be widespread | 15:29 |
| spotter | apw: well, it installed | 15:30 |
| spotter | but for some reason it takes forever to boot | 15:30 |
| spotter | grub really takes forever | 15:30 |
| spotter | thought it was an issue with 12.04, so then installed debian squeeze | 15:30 |
| spotter | but same issue | 15:30 |
| apw | well grub is likely identicle in the two, same maintainers | 15:31 |
| spotter | yes | 15:31 |
| spotter | :) | 15:31 |
| spotter | wondering if its a grub2 issue, 4k cluster issue or something else | 15:31 |
| spotter | also upgraded bios in the process so too many variables (oopsy) | 15:31 |
| spotter | but it could be that I went from ubuntu's 3.2 based kernel to debian 2.6.32 (I think?) based kernel | 15:32 |
| tgardner | ogasawara, i386 chroot is done, armhf has started. | 15:32 |
| ogasawara | tgardner: cool, I'll kick off an i386 build. amd64 was fine, so I went ahead an pushed | 15:33 |
| spotter | anyways, just wanted to make sure you guys were aware of this can one of you file a bug as appropriate, I dont have an ubuntu system that can do anything with it so dont need to be kept in the loop :) | 15:34 |
| tgardner | sforshee, here is another failure to boot that might be related to Broadcom: bug #990879. Are you still looking into that ? | 16:06 |

| * ppisati -> gym/workout | 16:10 | |

| sforshee | tgardner, yep | 16:21 |
| tgardner | sforshee, cool | 16:22 |
| sforshee | tgardner, 990879 may actually be the same, the stacktrace is too abbreviated to tell | 16:22 |
| sforshee | i asked for hw data | 16:22 |
| tgardner | sforshee, yeah, I just thought it might be related because of mention of Broadcom and firmware | 16:23 |
| sforshee | tgardner, I overlooked that part. There's a good chance it is the same problem then. | 16:23 |
| tgardner | sforshee, is your patch in wireless-testing ? | 16:24 |
| sforshee | tgardner, yes it is | 16:24 |
| tgardner | sforshee, b43: only reload config after successful initialization ? | 16:24 |
| sforshee | that's the one | 16:24 |
| tgardner | sforshee, I might pull it in as a pre-stable for Precise | 16:25 |
| sforshee | tgardner, I'd say go for it. No one objected (or commented at all) on the list | 16:25 |
| tgardner | sforshee, its a pretty straight forward fix | 16:26 |

| tgardner | apw, any opinions on what we ought to do? | 17:03 |
| apw | tgardner, have we applied it to precise? i think we were talking about doing so only after the first sru round anyhow, so 3w or so | 17:04 |
