[Bug 1254672] Re: ps segfaults with qemu-arm-static
** Description changed: Host: Ubuntu Precise AMD64 - Guest: Debian Testing armhf + Guest: Debian Testing armhf (or armel) After running a debootstrap for Debian testing/armhf and entering the chroot, simply running ps causes a segmentation fault. $ sudo qemu-debootstrap --arch=armhf testing armhf http://ftp.uk.debian.org/debian/ [...] $ sudo chroot armhf # ps Signal 11 (SEGV) caught by ps (procps-ng version 3.3.4). /bin/ps:display.c:59: please report this bug I couldn't find a bug report for procps, which would be unusual if such a bug existed, so I'm assuming the bug is in qemu. Unfortunately trying to run debootstrap for an Ubuntu variant fails to find the release file. ps is used a lot, as you can imagine, but specifically it fails when trying to install some packages via apt-get install and no attempt is made to recover.

Same thing with qemu-mips-static too by the looks of things. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1254672 Title: ps segfaults with qemu-arm-static To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1254672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1254672] Re: ps segfaults with qemu-arm-static
I suspect this is a NULL pointer access that happens in procps where it isn't handling an error path that it's not expecting somehow (either a syscall we're not implementing, or perhaps something like /proc not being mounted in your chroot environment, or something about qemu's emulation of some file in /proc isn't right). The next stage would be to debug where exactly ps is crashing (attaching a debugger to the qemu gdbstub is probably easiest, or good old printfs...) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1254672 Title: ps segfaults with qemu-arm-static To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1254672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
