Post #3560937

A quick follow-up to this key wiping bug: Ondrej Kozina from the cryptsetup team was very quick to pick this up. Ondrej has developed a patch for cryptsetup which works around the kernel bug, which is scheduled to land in the upcoming 2.8.7 release: https://gitlab.com/cryptsetup/cryptsetup/-/merge_requests/937 Also, while reviewing my proposed kernel patch, Ondrej discovered a related issue in the loop block device system: https://lore.kernel.org/all/ea67ab0e-a039-460e-ab5b-a448995bbd31@redhat.com/ This means in particular that my one-line kernel patch is incomplete. It only covers the common case of having the encrypted volume on a physical block device rather than a virtual loop device. I really enjoyed these open-source interactions and am grateful for the work of Ondrej and all the others :-)
