ppisatiapw: CVE-2010-416011:39
ubot2ppisati: Multiple integer overflows in the (1) pppol2tp_sendmsg function in net/l2tp/l2tp_ppp.c, and the (2) l2tp_ip_sendmsg function in net/l2tp/l2tp_ip.c, in the PPPoL2TP and IPoL2TP implementations in the Linux kernel before 2.6.36.2 allow local users to cause a denial of service (heap memory corruption and panic) or possibly gain privileges via a crafted sendto call. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-4160)11:39
ppisatiapw: this is in our maverick/ti-omap4 tree: d428c4f08e29958d3d9dd3a2ea846ef5fce0366d11:47
ppisatiapw: and it's actually the cve fix: 9915672d41273f5b77f1b3c29b391ffb7732b84b11:48
blissi remember that bug11:48
ppisatibliss: good memories are hard to fade out :)11:49
blissha11:49
blissthe fix was putting in upper bounds on maximum iovec sizes in the sendmsg syscall path11:49
blissso that's the fix that should be backported, not just the corrections to the l2tp code11:50
blissshould prevent a bunch of other undiscovered vulns11:50
blisslet me peek at those commits11:50
ppisatibliss: i mispsated the CVE number, we are referring to 2010-4249 actually11:51
blissheh11:51
blissthat's the unix socket DoS?11:51
blissthat one looked like a pain to fix11:51
ppisatibliss: unic gc11:51

* ppisati today is unable to type anything correctly...11:52
blissheh, no worries11:53
alkisgHi, I have a kernel regression with a CDROM device (worked on lucid, doesn't work on maverick/natty). On the other hand, sandy bridge doesn't work on lucid, so I'm stuck with either the CDROM or the network adapter not working11:55
alkisgHow can I try the oneiric kernel to my lucid box?11:55
alkisgI tried the latest from http://kernel.ubuntu.com/~kernel-ppa/mainline but module-init-tools version is incompatible11:55
alkisgCan I install module-init-tools from oneiric to my lucid, or will that break something else?11:57
alkisgAh, no, dpkg version incompatible there11:57

alkisgThe regression is still there, i.e. the CDROM drive that is recognized in Lucid, is no longer recognized in Maverick, Natty and Oneiric.12:52
alkisgWhere would I file a bug for that?12:52

alkisgAnd, I'm not the one having the problem, I'm remote-supporting a fellow teacher, so I'd better gather any needed data now, I don't think he'll be able to do it himself later...12:53
sbtehi all, what's the reason all packages were pulled from the kernel ppa on launchpad?12:53
sbteis there a new suggested way for updating to 2.6.39+? (i'm on natty)12:54
slicksHey guys. Could Ypu help me? I don't know how to apply Ubuntu-specific patch on vanilla kernel. Downloaded linux-source-2.6.38.deb, installed it. In /usr/src/linux-source-2.6.38 I have folders: debian, debian.master and vanilla kernel archive: linux-source-2.6.38.tar.bz2. How should I proceed? Please help. I know only how to patch kernel with diff's :(13:52
slicksCould You*13:53
apwsbte: those were just testing kernels, preparitory to those being then in the real archive14:49
keesif only I had used askubuntu.com sooner. http://askubuntu.com/questions/4653/how-do-i-get-rid-of-u3-system-on-my-usb-drive15:49
andhi, I was trying to grab a package from the kernel team's PPA but looks like the page is currently empty (https://launchpad.net/~kernel-ppa/+archive/ppa), thus apt-get ignoring to update the repository. Any clue on how I can move forward? (I am on Lucid LTS)16:07
apwand: those were just testing kernels, preparitory to those being then in the real archive16:14
apwand: the lts has official packages that replace those16:14
andapw, ok, but I am actually running on 2.6.32-32, is there a way to download/install 2.6.38 for example?16:15
andshould I grab them on http://kernel.ubuntu.com/~kernel-ppa/mainline/ and manually install?16:16
manjoogasawara, were you looking for me ? 17:10
ogasawaramanjo: no, cking was17:10
ogasawaramanjo: he's just left to go find you17:10
manjoogasawara, ok thanks 17:11
sbteapw, sorry, xchat crashed. In reply to you: I know, but is there a different suggested way to update to a newer version of the kernel? I need it because 2.6.39+ has builtin wifi drivers for my card that don't cause kernel panics17:59

vishHi, I'm trying to bisect a kernel and while building, apart from the bisect, I change only the changelog with numbers ~bgo1234vish0 , ~bgo1234vish1  and so on.. but when I check using $uname -a  after booting into the newly build kernel, it only shows as ~bgo1234vish0 , the first build version number while the package number is the right one. 20:38
vishis that OK, or am I not building the right version?20:39
vishor how do I fix that numbering which displays in $uname -a ?20:39

brycehheya, I've been helping Stefan Stasik with a kernel bug on arrandale - lp #75878522:34
ubot2Launchpad bug 758785 in xserver-xorg-video-intel "[arrandale] Display flickers or blank on login (x86_64)" [Undecided,Invalid] https://launchpad.net/bugs/75878522:34
brycehhe's in the process of bisecting, and has a patch flagged that he's going to try and test (which I've linked on the bug)22:35
brycehI've tagged the bug kernel-handoff-graphics, but also pinging here since I think the bug may be close to solution and could probably benefit from a kernel engineer's attention22:36
