Title:
  unable to make backup link of `./usr/sbin/uuidd' before installing new
  version: Operation not permitted

Bug description:
  == SRU Justification ==

  Impact: Root in a user namespace cannot create new hardlinks to suid
  files owned by another user even when the inode owner is mapped into
  that user namespace. This is causing some package upgrades to fail in
  unprivileged containers.

  Fix: Patch from linux-next to allow a user with CAP_FOWNER in a user
  namespace to link to a suid inode if the inode owner is mapped into
  the user namespace.

  Regression Potential: The main risks here would be security related
  since the fix is a loosening of the protected_hardlinks sysctl which
  serves as a mitigation against some classes of security
  vulnerabilities. However a user which would now be allowed to link
  directly would generally be able to create links to the same file via
  other mechanisms already, so it's unlikely that this creates any
  additional attack surface in practice.
