| eb4890 | If people had to pick one kernel book, would it be Love's or Bovet and Cesate? Or something else. I'm looking to understand ASLR type systems. | 00:35 |
|---|---|---|
| jjohansen | eb4890: I've never read Bovet and Cesate so I can't compare, but Love's book was pretty good and easy to read | 00:39 |
| eb4890 | jjohansen: Thanks | 00:40 |
| jjohansen | eb4890: I'm not sure that is will cover ASLR though? Its been a while since I read it | 00:40 |
| eb4890 | jjohansen: As long as it covers building a process structure and where that is in the kernel code, I can at least look at the source. | 00:42 |
| jjohansen | eb4890: I think it will work for your purposes, make sure to get the 3rd edition as it is current to the .34 kernel | 00:44 |
| jjohansen | the 2nd edition is getting quite crufty | 00:45 |
| eb4890 | jjohansen: Thanks, I was wondering about getting the older cheaper book. | 00:46 |
| jjohansen | it would be good for concepts etc, but would current to early 2.6 (circa 2006 or so) | 00:47 |
| eb4890 | Hmm, Bovet and Cesati is published 2005. So would be equally old. I'll go with the 3rd edition of Love's book. Thanks. | 00:51 |
| Kano | hi apw, can you trigger 2.6.37 mainline build? | 01:41 |
| yigal | where can I find a default config for an earlier Ubuntu release, in this case Karmic - I'm building on Maverick - by the way should I be able to do this build without difficulty? | 02:13 |
| yigal | is there an easier way than downloading the deb installing and copying the config from /boot ? | 02:15 |
| Kano | the config does not really matter | 02:16 |
| Kano | it should be compatible | 02:16 |
| yigal | ok, cool | 02:16 |
| yigal | that would definately make things easier | 02:16 |
| Kano | i use mainline kernels even for debian lenny, just with a few modeset overrides if needed | 02:17 |
| yigal | I just patched Maverick's kernel to get a touchscreen to work and I want to do the same for Karmic's now but compiling still in the Maverick box | 02:18 |
| Kano | just use the same kernel | 02:20 |
| yigal | Inte's GMA 500 GPU makes that impossible | 02:22 |
| yigal | s/Ite/l/ | 02:23 |
| yigal | man, s/Inte/l/ | 02:23 |
| Kano | why | 02:23 |
| yigal | the PSB kernel used for the GPU had to be tweaked after 2.6.32 so Karmic has a different PSB driver than Meerkat's | 02:26 |
| yigal | PSB driver | 02:26 |
| yigal | sorry | 02:26 |
| bullgard4 | What does "md" stand for in /lib/modules/2.6.35-24-generic/kernel/drivers/md/ ? | 04:06 |

| apw | smb, ning indeed | 09:11 |

| === diwic_afk is now known as diwic | ||
| apw_ | smb is yhete anything else outstanding for natty that u want in the uploaf? | 12:23 |
| apw_ | also should i wait on tedting by jj for that one? | 12:24 |
| smb | apw, Either you switched to an ancient form of English or you are trying to type on the nexus. :) | 12:55 |
| smb | Atm, I got nothing else for Natty | 12:55 |
| apw | smb, indeed | 12:56 |
| smb | Given the (health) status of jj I am not sure whether or when he may respond. So I bravely vote for just putting it in and then hide from the fallout | 12:57 |
| apw | smb, heh good point indeed | 12:57 |
| smb | apw, Hm I see some report back that the sata link power management may still be an issue even with Natty. Though that needs the user-space "fix" | 12:59 |
| apw | smb is export SATA_ALPM_ENABLE=false the work around in all releases ? | 13:02 |
| smb | I am not sure. I believe the whole script was removed in older releases. But when the new script does support a switch the fix may as well be a change of default | 13:03 |
| smb | I have/had systems which worked ok with it enabled, so this seems a controller and/or drive specific issue. Not sure whether we want to start quirking in userspace. Especially since it will be a bitch to keep up with finding the bad or good combinations | 13:05 |
| apw | yeah as you say it cannot be all machines, though i guess many may not support it at all | 13:06 |
| smb | apw, I wonder whether it would be worth the effort of starting some sort of wiki to gather good and bad experience cases (like for the suspend resume) | 13:07 |
| apw | smb, yeah ... perhaps ... i also note you have that marked fix released for natty which seems wrong | 13:07 |
| smb | It likely was done based on the "it works since then" comment which seems to be only partially correct (if at all) | 13:08 |
| smb | So we may need to put it back into open state | 13:09 |
| smb | Or start a new one for data mining | 13:09 |
| apw | smb, move it back to New | 13:10 |
| smb | apw, I added some comment as well | 13:21 |
| apw | smb, gah there are so many bugs there is no safe ground left | 13:23 |
| smb | Safe ground is an illusion anyway when moving at roughly 1600km per hour | 13:26 |
| apw | smb, heh :) | 13:27 |

| hallyn | to submit a kernel patch for maverick kernel, what's the preferred method? A debdiff? A git tree on ubuntu.kernel.com? A compiled package in a ppa? (To put in a launchpad bug) | 15:16 |
| smb | If things are bigger (which they usually should not be for a SRU) it would be a tree and git pull. For smaller things a patch exported with format-patch and sent to kernel-team mailing list with the sru justification (the justification should also go into the bug report and the patch would be nice to have there) | 15:19 |

| apw | hallyn, as its for a released kernel it needs to have a LP bug associated | 16:55 |
| hallyn | apw: yup, it does | 16:58 |
| apw | hallyn, please include the BugLink: | 16:58 |
| hallyn | apw: yup, it's in the patch. Just waiting for the thing to build so I can have the bug submitter test first :) | 17:01 |

| apw | tgardner, can you remember what the source package for the nvidia binary drivers is | 18:12 |

| apw | jjohansen, hey ... smb tested that disk rename and had no issues, so i am proposing to upload it pretty soon | 18:19 |
| jjohansen | apw: +1 | 18:19 |
| apw | jjohansen, cirtainly like something which rambo would use, 2 inch slugs | 18:19 |
| jjohansen | apw: like I said I was surprised it didn't work for me | 18:19 |

| tgardner | apw, bug #683690 may have a solution in staging (which we should likely turn on) | 20:16 |
| ubot2 | Launchpad bug 683690 in linux (Ubuntu) "CONFIG_NLS_DEFAULT should be set to UTF8 (affects: 1) (heat: 96)" [Undecided,New] https://launchpad.net/bugs/683690 | 20:16 |
| apw | tgardner, thanks | 20:26 |
| tgardner | apw, actuall, on deeper inspection it appears we should just set CONFIG_NLS_DEFAULT="utf8" | 20:27 |
| ogra | apw, thanks for omap3 | 20:27 |
| apw | tgardner, will do some research as to what that means | 20:27 |
| apw | and if there is any downsides | 20:27 |
| tgardner | apw, the staging driver is for mounting SMB file systems without having a user space component (I think) | 20:28 |
| apw | yeah sounds like just a config change request | 20:28 |
| apw | tgardner, what was the modules we built in recent, was it crc32 or something ... can you remember why we did that | 20:28 |
| tgardner | dynamic linking | 20:29 |
| tgardner | no module aliasis, so the netboot stuff was failing | 20:29 |
| tgardner | dynamic registration, rather | 20:29 |
| apw | ahh right | 20:30 |
| tgardner | apw, I went ahead and pushed CONFIG_NLS_DEFAULT="utf8" on master-next. Lets see what havoc it wreaks. | 20:47 |
| apw | tgardner, ok thanks | 20:48 |
| sconklin | apw, tgardner - I'm out of the Lucid tree and there is a new master-next open for business | 21:25 |

| hallyn | jjohansen: hey - when doing my own funky patched kernels I understand having to skip abi checks, but I took a stock git://kernel.ubuntu.com/git/ubuntu-maverick kernel plus one small patch, but ppa gave me https://launchpad.net/~serge-hallyn/+archive/testkernel/+build/2125626 | 22:20 |
| hallyn | jjohansen: (since i know you've got ppa kernel experience :) is there something else I'm missing? I don't want to turn off checks if I'm doing something else wrong... | 22:21 |
| jjohansen | hallyn: if the patch caused any abi change you have to go through an abi bump or turn off the checks | 22:26 |
| jjohansen | its an absolute pita | 22:26 |
| hallyn | it shouldn't have caused an abi bump though | 22:29 |
| hallyn | what causes an abi change? | 22:29 |
| jjohansen | hrmmm, well that should just be the regular kernel compile abi stuff | 22:29 |
| jjohansen | its then compared to the one stored in debian.master | 22:30 |
| jjohansen | hallyn: did you mess with the kernel version numbering? | 22:30 |
| jjohansen | that can cause the abi check to fail too | 22:30 |
| jjohansen | basically it compares the compiled kernel to the one stored in debian.master/abi/ | 22:31 |
| hallyn | well i named it linux_2.6.35-24.42qemui386v3 | 22:32 |
| jjohansen | the version numbering must be exactly one back or the comparision fails | 22:32 |
| hallyn | alrighty, my fault then :) | 22:32 |
| jjohansen | what is in the debian.master/abi/ dir | 22:32 |
