| AlanBell | hi all | 10:27 |
| fairuz | hey | 10:28 |
| AlanBell | it seems that there are speakup modules on the natty cd, and also built into the kernel | 10:28 |
| AlanBell | just been discussing in -accessibility | 10:28 |
| AlanBell | in drivers/staging/speakup | 10:28 |
| AlanBell | apparently it doesn't need to be there as a module as it is in the kernel from .37 | 10:29 |
| apw | pgraner, glxinfo -l | grep GL_MAX_TEXTURE_SIZE | 10:32 |
| apw | AlanBell, ? you are saying we are carrying .ko's and its built in? | 10:32 |
| AlanBell | apw: yeah | 10:37 |
| AlanBell | actually I am passing on the message, I barely understand it myself | 10:37 |
| AlanBell | a blind user who uses speakup and knows way more about it than me pointed it out | 10:38 |
| apw | AlanBell, where can i get more information :) | 10:48 |
| AlanBell | apw: join #ubuntu-accessibility and ask webczat | 10:50 |

| apw | bjf, whoever changes that one did it wrong :/ | 16:43 |
| bjf | apw, in the README it looked like N/A was an acceptable value | 16:43 |

| ubot2 | bjf: Race condition in the cm_work_handler function in the InfiniBand driver (drivers/infiniband/core/cma.c) in Linux kernel 2.6.x allows remote attackers to cause a denial of service (panic) by sending an InfiniBand request while other request handlers are still running, which triggers an invalid pointer dereference.

| tgardner | bjf, that was the one already applied to Maverick, right? | 16:51 |
| bjf | tgardner, looks like it got applied to dapper master-next, that's all i wanted | 16:51 |
| bjf | tgardner, yes | 16:51 |
| tgardner | bjf, what about Lucid ? | 16:52 |
| bjf | tgardner, got picked up via a stable release | 16:52 |
| bjf | tgardner, i'll double check | 16:52 |
| tgardner | bjf, dapper was acked by ogasawara and myself | 16:53 |
| bjf | tgardner, ok, i guess i missed that | 16:53 |

| tgardner | ogasawara, gcc 4.6 builds the oneiric kernel OK, though there are a lot on new warnings about unused variables. | 20:21 |
| ogasawara | tgardner: cool | 20:22 |
| ogasawara | tgardner: I'm gonna be away on Friday, so if you get antsy and want to upload Oneiric to the archive, feel free. | 20:23 |
| tgardner | ogasawara, antsy huh? :) I'll have to upload fairly soon to get libc-dev built. | 20:24 |
| herton | tgardner: there was some recent discussion on lkml about these new warnings (https://lkml.org/lkml/2011/4/21/324) | 20:24 |
| tgardner | herton, yep, saw those. I think they are now disabled? | 20:25 |
| tgardner | or soon will be | 20:25 |
| herton | tgardner: yep, from what I remember under make W=1 or more | 20:25 |
| herton | (that is, disabled by default, can enable again with W=1 etc.) | 20:26 |

| LLStarks | any chance that oneiric will fit the window for 2.6.40? nvidia optimus support might make it in provided that xserver 1.11 also makes it. | 20:47 |
| ogasawara | LLStarks: I suspect it'll be 2.6.40, but we'll officially discuss this at UDS in 2 weeks | 20:48 |
| mick_laptop | hi everyone, 5 channels later I'm here | 21:08 |
| mick_laptop | I'm trying to track down what I believe to be a kernel issue - is anyone around for me to poke if I have issues? | 21:08 |
| mick_laptop | in short when I copy a file (locally or over ethernet) after a certain percentage- my box freezes and my mouse etc becomes unresponsive | 21:08 |
| mick_laptop | when I did: wget -c http://192.168.x.x/ubuntu.iso my box would freeze after 82%. When I did: unsquashfs on filesystem.squashfs (cp'ed from /casper on the install iso) - after 2% it always hangs | 21:08 |
| hallyn | mick_laptop: on bare metal, or in a vm? | 21:09 |
| mick_laptop | hallyn: bare, fresh 10.10 install | 21:09 |
| hallyn | jinkeys | 21:10 |
| hallyn | have you ran the memory test (from the grub menu)? | 21:10 |
| tgardner | mick_laptop, get subscribed to -proposed and make sure this issue hasn't already been fixed by the latest kernel. | 21:11 |
| mick_laptop | no, I'm trying to get a vanilla kernel going to see if it happens on a non-ubuntufied kernel :) | 21:11 |
| mick_laptop | tgardner: -proposed a ml? | 21:11 |
| tgardner | mick_laptop, no, in your apt repository settings. | 21:12 |
| mick_laptop | ok, what should i try first? check ram, -proposed, or try other kernel? (I'm in the middle of a "make") | 21:13 |
| mick_laptop | tgardner: ok, so where do i add that, in /etc/apt/sources.list ? | 21:14 |
| tgardner | mick_laptop, we've also got prebuilt packages for mainline. | 21:15 |
| tgardner | mick_laptop, re: /etc/apt/sources.list: yes | 21:15 |
| mick_laptop | on what line? - maverick-updates ? | 21:15 |
| tgardner | mick_laptop, duplicate that line, then change updates to proposed | 21:16 |
| tgardner | mick_laptop, mainline builds are described here: https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds | 21:16 |
| mick_laptop | thanks | 21:17 |
| bjf | kees, there is no comment for CVE-2010-4656 to match up with the supposed upstream patch | 21:38 |
| ubot2 | bjf: ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-4656) | 21:38 |
| mick_laptop | how do i know what kernel to d/l? | 21:39 |
| mick_laptop | i guess +0.1 from uname -r | 21:41 |
| tgardner | mick_laptop, Maverick? http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35.12-maverick | 21:43 |
| mick_laptop | thanks | 21:47 |
| kees | bjf: let me go look, one sec | 21:52 |
| kees | bjf: ah, I can add the oss-security url where the CVE was assigned. http://www.openwall.com/lists/oss-security/2011/01/25/5 | 21:54 |
| bjf | kees, you may also want to look at the mailing list where we are discussing if the patch for 1017 is really the correct one | 21:55 |
| * kees looks | 21:56 | |
| kees | bjf: it seems like that thread got resolved? c340b1d640001c8c9ecff74f68fd90422ae2448a is for CVE-2011-1017 etc | 22:03 |
| ubot2 | kees: 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) | 22:03 |
| kees | bjf: based on the oss-security thread, that's correct, and the other 2 tardner found are for the other two CVEs. | 22:04 |
| mick_laptop | so far no crash | 22:04 |
| mick_laptop | looking good | 22:04 |
| bjf | kees, there is no direct connection between the commit and the CVE, there is a question by tgardner on the specific patch submitted to the ubuntu-kernel-mailing list | 22:04 |
| kees | oh, I was reading the SRU thread. the connection I found is this: http://openwall.com/lists/oss-security/2011/04/12/6 | 22:05 |
| kees | that's the oss-security thread linked to from the mitre CVE | 22:06 |
| kees | bjf: should I reply to the kernel-team thread with that oss-security link? | 22:09 |
| bjf | kees, i just did, thanks for looking at it | 22:09 |
| kees | bjf: ah, cool, okay. | 22:10 |
| mick_laptop | it just crashed again | 22:35 |
| mick_laptop | shit | 22:35 |
| mick_laptop | someone mind helping me triage this? | 22:35 |
| mick_laptop | hallyn: I guess I'll start w/ the memory test | 22:35 |
| mick_laptop | hallyn: how do i get grub to come up | 22:37 |
| mick_laptop | it seems to be skipped, I guess I'll check the grub configuration | 22:37 |
| hallyn | mick_laptop: i think you hold down 'shift' while it's rebooting | 22:39 |
| mick_laptop | trying that... | 22:40 |
| mick_laptop | nope | 22:41 |
| mick_laptop | not it | 22:41 |
| mick_laptop | i'm trying to find the thing that pauses it under /boot/grub/grub.cfg | 22:52 |
| mick_laptop | i made it show, but it went away in a second | 22:53 |
| * mick_laptop tries again | 22:53 | |
| bjf | mick_laptop, hold down the left shift key when you reboot | 22:53 |
| mick_laptop | i did | 22:53 |
| mick_laptop | didn't help | 22:53 |
| bjf | mick_laptop, i should say, as it is booting | 22:53 |
| mick_laptop | let me reitterate... i did | 22:54 |
| mick_laptop | i think it is grub_hidden_timeout (in caps) that is the right var... | 22:54 |
| mick_laptop | ok, i'm in doing memtest | 22:59 |
| mick_laptop | ok, so if the memtest comes back ok - where do i go from there? | 23:00 |
| mick_laptop | it seems like the kernel isn't logging the crashes | 23:01 |
| mick_laptop | nothing obvious in files under /var/log or dmesg | 23:01 |
| mick_laptop | is there some type of a debug flag that i can set? | 23:02 |
| mick_laptop | or a howto triage potential kernel issues? | 23:02 |
| mick_laptop | howto on triaging* | 23:02 |
| bjf | mick_laptop: https://wiki.ubuntu.com/Kernel | 23:03 |
| mick_laptop | ok, after a bunch of reading.... apt-get install linux-crashdump | 23:06 |
| mick_laptop | i'll rtfm (manpage) and go from there | 23:06 |
| === bjf is now known as bjf[afk] | ||
