I believe a command sequence like this can be used to reliably reproduce the issue:
umount /mnt truncate -s128m /tmp/test.img cmd="/sbin/mkfs.ext3 -E stride=128,stripe_width=512 -F /tmp/test.img" echo $cmd > /dev/kmsg $cmd mount -o loop /tmp/test.img /mnt/ while dd if=/dev/zero of=/mnt/$RANDOM bs=1M count=1; do true; done I do not see any failures when ext4 is replaced for ext3 above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789131 Title: Probable regression with EXT3 file systems and CVE-2018-1093 patches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1789131/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
