| kees | say, will saucy be 3.11 or 3.12 do you think? | 00:21 |
|---|---|---|
| elmo | kees: you mean trusty? | 00:28 |
| elmo | kees: because saucy is already 3.11 ;-) | 00:29 |
| kees | elmo: argh, off-by-one error. _trusty_, yes :) | 00:29 |
| kees | aaah, never mind. | 00:30 |
| kees | linux | 3.12.0-5.13 | trusty/main | 00:30 |
| Sarvatt | kees: its going to be 3.13 | 00:41 |
| kees | Sarvatt: okay, cool, thanks :) | 00:42 |

| smoser | hey. | 14:04 |
| smoser | do we have any sort of benchmarks that are done and recorded for kernel releases ? | 14:05 |
| smb | smoser, sconklin has been working on some storage/fs ones | 14:06 |
| smoser | i'm wondering because i have extremely unscientific data in my head that recent trusty is not performing as well as previous releases on my laptop. | 14:06 |
| smoser | that unscientific data "feels" like IO to me. | 14:06 |
| smb | smoser, iirc there _was_ a regression in ext4 which cking found but that was saucy, I think | 14:07 |
| smoser | smb, as in fixed ? | 14:08 |
| smb | smoser, Yes, also going to S | 14:09 |
| smoser | are the benchmarks sconklin has available ? | 14:10 |
| cking | smoser, it was address in bug 1242812 | 14:11 |
| ubot2` | Launchpad bug 1242812 in linux (Ubuntu) "ext4 random block I/O write performance regression with 3.11 Saucy Kernel" [Medium,Fix released] https://launchpad.net/bugs/1242812 | 14:11 |
| cking | it appeared in one of the power regression tests, but those tests are now busted, pending QA to plug in the H/W again | 14:13 |
| apw | smoser, and remember we're on 3.12 in trusty atm | 14:47 |
| tseliot | apw: what kernel version are we going to use in 14.04? | 16:20 |
| bjf | tseliot, 3.13 | 16:22 |
| tseliot | bjf: thanks | 16:22 |
| apw | that ;) | 16:24 |
| tseliot | :) | 16:25 |
| hallyn_ | apw: http://lkml.org/lkml/2013/12/4/156 i'm going to review this patchset asap, we may need it in trusty for userns containers to work nicely | 18:05 |
| hallyn_ | (to allow writing to /proc/self/loginuid) | 18:05 |
| apw | hallyn_, 0/20 ... really | 18:09 |
| apw | sigh | 18:12 |
| hallyn_ | apw: :( | 18:16 |
| hallyn_ | apw: i'll take a look this afternoon to see if it's actually complicated, or just long-winded or very broken up | 18:17 |
| apw | how did we get so far from having the patches we needed as we were at vUDS | 18:17 |
| apw | we so do not want to be introducing a new heap of abi if they anr't sure this is the way upstream either, gah | 18:18 |
| apw | also it seems to claim to be incomplete | 18:19 |
| apw | >> This patchset still need some work, such as allow changing | 18:19 |
| apw | >> audit_enabled in audit namespace, auditd wants this feature. | 18:19 |
| apw | >> | 18:19 |
| apw | and it doesn't sound like upstream will even start looking at it for weeks yet | 18:21 |
| apw | hallyn_, plus this calls itself 'part1' and the previous version was 00/48 ... are we sure this is even all of it ? | 18:24 |
| hallyn_ | 18:17 < apw> how did we get so far from having the patches we needed as we were at vUDS | 18:25 |
| hallyn_ | well all *we* need is /proc/$$/loginuid writeable. there maybe a shorter way to do it, i simply haven't looked. | 18:26 |
| hallyn_ | i only know that fedora has the same issue and they claimed to be waitin go this patchset | 18:26 |
| hallyn_ | apw: we *can* work around it in userspace if there's not a clean patchset we can use | 18:27 |
| ohsix | isn't it immutable for the purpose of auditing? | 18:27 |
| apw | ohsix, it is less immutable, as 'change able once able' | 18:28 |
| apw | and i assume hallyn_ wants to make the init in a container be able to set it once again | 18:28 |
| ohsix | ah | 18:28 |
| ohsix | i wonder why someone hasn't proposed just adding another one, maybe one that keeps a list of ones that have been set or something | 18:29 |
| apw | i guess it makes sense if you have a uidns that you might want to have audit be reset in there, hrm | 18:29 |
| hallyn_ | apw: well tbh none of it makes sense to me - i thought loginuid should be only for LSPP cred tracking for audit, but it seemingly is now being abused | 18:36 |
| apw | hallyn_, it does look like it is doing more than making that writable for sure, it is splitting auditd as well | 18:36 |
| apw | blimey this is tensy changes | 18:46 |
| * apw notes it is well past beer-o-clock and goes and does somwething abou tit | 19:05 | |
| cking | yeah, well into beer time now | 19:26 |
