We found the issue -- I think xnox is going to report it via proper channels. But basically it's this:
<mwhudson> sizeof(dev_t) = 4 sizeof(__kernel_old_dev_t) = 8 This makes the kernel's loop_info 8 bytes bigger than klibc's and so the kernel is writing past the end of the loopinfo on the stack, which until now has avoided causing problems by sheer luck. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850184 Title: losetup -f broken in 2.0.6-1ubuntu2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/klibc/+bug/1850184/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
