| madrazr | Hii all, yesterday there was a session on Building Upstream kernels at #ubuntu-classroom. I just had this question but unfortunately could not ask. | 03:46 |
|---|---|---|
| madrazr | Suppose I now have the rpm-src of the Fedora 8 kernel and I want to build it for Ubuntu, how to do it? | 03:47 |
| madrazr | I badly want this because, there is a tool called NCTUNS, which must be mandatorily used by students as per the University for Networks Simulation and this runs only on Fedora | 03:49 |
| cradek | maybe you could extract the source from that rpm with rpm2cpio and build it. but I'm pretty sure this is not the right channel for rpm questions. | 03:55 |
| pwnguin | madrazr: is the source to nctuns available? | 04:14 |
| madrazr | pwnguin: yes | 04:15 |
| madrazr | pwnguin: can some one build it for Ubuntu, I am ready to take the initiative but I am not well versed in Ubuntu package maintainance | 04:16 |
| madrazr | So If someone helps me, we can bring it to Ubuntu and I can pursuade my college authorities to use Ubuntu from nowonwards | 04:16 |
| pwnguin | im grabbing a tar.gz right now, but im not clear what on earth it is | 04:17 |
| madrazr | We are actually not happy with Fedora, and we want to shift to Ubuntu, but NCTUNS is standing in between our college and Ubuntu | 04:17 |
| pwnguin | it has linux 2.6.24 as part of then ame | 04:17 |
| madrazr | pwnguin: can you link me to the page frm where you are downloading? | 04:17 |
| pwnguin | no | 04:19 |
| pwnguin | stupid frames | 04:19 |
| pwnguin | my first guess is something related to tun | 04:19 |
| madrazr | pwnguin: I did not get you | 04:20 |
| pwnguin | http://nsl10.csie.nctu.edu.tw/ | 04:20 |
| pwnguin | that place uses frames well enough that i cant figure out what link to give you | 04:20 |
| madrazr | http://nsl10.csie.nctu.edu.tw/products/nctuns/download/download.php | 04:20 |
| madrazr | this is the link to download page | 04:21 |
| pwnguin | like i said, im downloading now | 04:21 |
| madrazr | oh sorry, fine then | 04:21 |
| pwnguin | anyways, you might consider attending a session by dholbach tomorrow on making packages | 04:22 |
| madrazr | pwnguin: ok | 04:22 |
| pwnguin | but really, i dont see this happening if it involves patching the kernel | 04:23 |
| madrazr | pwnguin: why so? | 04:24 |
| madrazr | pwnguin: how can end users use this tool then? | 04:25 |
| madrazr | pwnguin: cant we have a NCTUNS supporting kernel in repos, so those who want to use NCTUNS can install this kernel, actually thats what happens when we install it on Fedora | 04:26 |
| madrazr | Grub gives a separate option at boot time | 04:26 |
| pwnguin | from what i can tell, this NCTUNS provides a patched kernel for fedora and the application uses it to attach to a special network emulator forked from tun | 04:26 |
| madrazr | pwnguin: yes it does so | 04:29 |
| pwnguin | who would maintain this kernel? | 04:29 |
| madrazr | this patched kernel?? | 04:29 |
| pwnguin | yes | 04:29 |
| madrazr | its maintained by those developers only | 04:29 |
| pwnguin | indeed | 04:29 |
| madrazr | pwnguin: so do you mean to say, until those people provide patches to Ubuntu kernel, no one can help us? | 04:30 |
| pwnguin | What I mean to say is that ubuntu is fairly burdened already, especially on the kernel. If someone new were to step up and meet the obligations, that would be one thing | 04:31 |
| pwnguin | if the NCTUNS had put their patches into the kernel tree, that'd be another thing | 04:31 |
| pwnguin | but asking ubuntu to pick up a fedora package that even fedora hasn't picked up seems a bit silly | 04:31 |
| madrazr | pwnguin: ok fine, suppose I am ready to maintain the packages and I am ready to take the initiative for making it work on, what kind of support will I get from Ubuntu community and kernel team? | 04:33 |
| pwnguin | well, dholbach will love you | 04:33 |
| madrazr | pwnguin: sooper, where can I find him?? | 04:34 |
| madrazr | which channel? | 04:34 |
| pwnguin | #ubuntu-motu | 04:34 |
| madrazr | pwnguin: fine, thanks a lot | 04:34 |
| pwnguin | you should also write the kernel mailing list | 04:34 |
| madrazr | pwnguin: ubuntu kernel mailing list? | 04:34 |
| pwnguin | yea | 04:34 |
| pwnguin | about whether the patches are okay or not | 04:35 |
| madrazr | fine | 04:35 |
| madrazr | pwnguin: actually I dont know where to get started, thats the whole problem here now, because I am not very well versed with Kernel development | 04:35 |
| pwnguin | well, in your case | 04:35 |
| pwnguin | the first thing to do is make an actual patch | 04:35 |
| pwnguin | they provide a set of files, but they're not in patch format | 04:36 |
| pwnguin | you might also write the NCTUNS folk and ask them if they have plans to get the nctun interface into the kernel | 04:37 |
| pwnguin | linus' kernel | 04:37 |
| madrazr | ok | 04:37 |
| pwnguin | the patch would make it easier to evaluate whether the modifications to say, syscall_table is dangerous etc | 04:40 |
| pwnguin | im not even sure regular tun is still in the kernel | 04:40 |
| madrazr | ok | 04:41 |
| pwnguin | anyways, if the kernel team were to decide this was worthy of inclusion in ubuntu mainline, you'd basically provide a patch and they'd include it, then the rest of the work would be in MOTU -- but the idea of providing a special nctun build of the kernel I don't think will fly | 04:42 |
| pwnguin | maybe I'm wrong | 04:43 |
| madrazr | pwnguin: ok | 04:44 |
| ackrcv1 | Hi, how do I go about installing 2.6.25 for 8.04? | 06:24 |
| Saied | is there a 2.6.25 kernel available for ubuntu? | 10:27 |

| BenC | Ok people...there's supposed to be a kernel meeting today, but there's not much to discuss on account of work is starting for intrepid | 17:08 |
| BenC | But if anyone has any questions, we can answer them now | 17:08 |
| laga | (i've got a question about a bug report, but i'm not sure if it's appropriate for the meeting) | 17:09 |
| BenC | Closer to UDS we will review the topics for the kernel track, and we invite people to add to the list of topics | 17:09 |
| BenC | laga: It's usually not, but for lack of anything else to discuss, feel free to bug drop :) | 17:09 |
| laga | sure. i'll just need a minute to make thunderbird behave again.. | 17:10 |
| laga | https://bugs.launchpad.net/bugs/223381 | 17:11 |
| laga | that guy basically suggests a change to CONFIG_HZ to get his remote working, and i'm not sure if that's the right way ;) any advice? | 17:11 |
| smb | laga: To throw in my opinion, I agree with your initial answer. A driver that requires a certain HZ number is broken and should be fixed instead of changing HZ. | 17:24 |
| BenC | Yeah, that's my answer too | 17:30 |
| laga | good, thanks | 17:32 |
| alex_joni | BenC: mind if I jump in with a question? | 17:49 |
| BenC | alex_joni: sure | 17:49 |
| alex_joni | abogani asked me if I plan to push the custom flavour I did for hardy (IPIPE patch in the kernel, and RTAI packages) back to Ubuntu | 17:50 |
| alex_joni | so far I haven't considered it (until he approached me), mainly because I didn't think there's enough interest.. also maintaining might be a bit of a problem | 17:51 |
| alex_joni | are there any thoughts/pages about processes like these? | 17:51 |
| alex_joni | BenC: was that so scary? | 18:58 |
| BenC | alex_joni: It's all documented in source in debian/binary-custom.d/ in the git tree | 19:00 |
| BenC | alex_joni: the other thing is we need reassurances that it will be maintained, especially post-release | 19:00 |
| BenC | we generally like to see a team behind custom flavors and someone who will respond immediately when we see a build failure cause by patch conflicts | 19:01 |
| alex_joni | I see | 19:01 |
| alex_joni | well, I'll talk to abogani about it | 19:02 |
| alex_joni | I'm also concearned I don't have the time/energy for long-term support | 19:03 |
| BenC | May be best to keep it in a PPA then | 19:07 |
| alex_joni | ppa? | 19:08 |
| amitk | alex_joni: ppa = personal package archives, feature of launchpad to allow users to upload source deb package and have it spit out Ubuntu binaries. It also provides a way to host your own packages | 19:41 |
| alex_joni | amitk: I have a repo set up | 19:45 |
| alex_joni | with proper package signing, etc | 19:45 |
| amitk | alex_joni: in that case you probably don't care about ppa | 20:02 |
| pwnguin | unless you're popular and want canonical to foot the hosting bill ;) | 20:05 |
| alex_joni | cjwatson: any idea what this means? http://pastebin.ca/1002222 | 22:04 |
| cjwatson | alex_joni: no, although the /dev/sda I/O error suggests hardware trouble | 22:06 |
| smb | alex_joni: this means the block layer returned one sector bad. | 22:07 |
| alex_joni | so it's faulty HW ? | 22:07 |
| smb | alex_joni: somewhere yes. but depending on hw setup could be somewhere one the way down to the disk. is that a real scsi disk or sata? | 22:09 |
| alex_joni | sata | 22:10 |
| alex_joni | smb: so it could be a problematic driver of the chipset or something like that? | 22:10 |
| smb | alex_joni: the message itself comes from the generic block layer. normally the drivers would or could issue additional info. it could even be a bad sector on the disk. or bad cable (if the error is not always the same sector) | 22:12 |
| alex_joni | smb: ok, I'll poke it some more | 22:12 |
| smb | alex_joni: is there anything before that message? | 22:12 |
| alex_joni | smb: it's a livecd I built, run by another user.. I'll have him run with nosplash, and without quiet | 22:13 |
| smb | alex_joni: ah, ok | 22:13 |
| alex_joni | thanks for the pointers | 22:13 |
| smb | alex_joni: np :) | 22:15 |
