[Ubuntu-x-swat] [Bug 968218] Re: ssh x11 forwarding precise to oneiric causes glibc malloc(): memory corruption
Instead of the patch in #16 (which has an error), I found that the original upstream patch applies and builds fine against lucid's libxi 1.3. Comparing the upstream patch with what jcristau prepared for debian, they look functionally the same (just formatting changes). There are no Ubuntu changes to the package in lucid, so I think carrying the upstream patch is the cleaner solution. I sponsored an upload Robert's debdiff of the oneiric-proposed package, and uploaded a package for lucid-proposed with the original patch. It should be pretty obvious whether these work or not, but please do ensure both oneiric-proposed and lucid-proposed get tested for verification. ** Changed in: libxi (Ubuntu Oneiric) Status: Triaged = Fix Committed ** Changed in: libxi (Ubuntu Lucid) Importance: Undecided = High ** Changed in: libxi (Ubuntu Lucid) Status: New = Fix Committed -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxi in Ubuntu. https://bugs.launchpad.net/bugs/968218 Title: ssh x11 forwarding precise to oneiric causes glibc malloc(): memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libxi/+bug/968218/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Hi Bryce, I tried backtracing X11 using those instructions, but couldn't get X11 on either the Precise or the Oneiric side to give me a backtrace (because it didn't actually crash).

Can you please give the libxi in this PPA a try on the oneiric machine? https://launchpad.net/~sarvatt/+archive/green It is a backport of http://cgit.freedesktop.org/xorg/lib/libXi/commit/?h=libXi-1.4-branchid=22e9ace88d57803ecda95db7c9355a614db1902a which was shown to fix the same issue in other places, with minor changes to apply with our XI2.1 stuff in oneiric's libxi. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/968218 Title: ssh x11 forwarding precise to oneiric causes glibc malloc(): memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/968218/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 968218] Re: ssh x11 forwarding precise to oneiric causes glibc malloc(): memory corruption
Hey Robert, I actually was encountering this exact same crash with Virtualbox on an oneiric server when X forwarding from a precise machine. I installed that patched libxi6 on the oneiric server and it fixed the problem.

I have seen this on two client machines (a laptop and a desktop) running - the latest oneiric release, connecting to either the oneiric desktop + the latest precise release, connecting to either the oneiric desktop release or oneiric server release on the server side. I have also reproduced this with two VirtualBox VMs, connected together with host- only networking and with desktop releases of Oneiric and Precise installed. To reproduce: - On client machine, install Precise with all updates as of 2012-03-29. - On server machine, install Oneiric with all updates as of 2012-03-29. - Set up host-only networking so that machines can ssh to each other. - On client machine, ssh -X to the server machine. Then run an X11 application. Some applications will crash immediately or on the first mouse click on that application. On my test VirtualBox setup, applications that always crash on first click: - gnome-terminal - nautilus - aisleriot solitaire - gnome-control-center - file-roller - firefox - brasero - gcalctool - palimpsest Applications that do not crash: - Libre Office - gimp - banshee - firefox - thunderbird Obviously, this isn't an exhaustive list, but you get the idea. When applications crash, they spew out a large error message. On my desktop machine, sshing in to an Oneiric Server install on a physical machine, the programs crash immediately without showing a window, but on my test setup with two VirtualBox VMs, you first have to click on the window to cause it to crash.

I've just tested SSHing from Precise to Natty and everything seems to work fine.
