[Bug 1063061] Re: please backport support for EFI vars > 1KB

[Launchpad Bug Tracker]

This bug was fixed in the package sbsigntool - 0.6-0ubuntu1

---------------
sbsigntool (0.6-0ubuntu1) quantal; urgency=low

  * New upstream release.
    - Uses the new mount point for the efivars directory, for compatibility
      with the pending upstream kernel patches and compatibility with what
      mountall is doing.  LP: #1063061.
    - Fixes sbverify verification of the pkcs7 bundles that Microsoft-signed
      binaries deliver to us, enabling us to do build-time verification of
      shim-signed.

Bug description:
  As of Linux 3.5, it is not possible to update the SecureBoot database
  from userspace because the sysfs implementation only supports variable
  data up to 1KB in size and this is exceeded by even a minimum key
  database of one key.

  Matt Fleming has accepted a patch from Matthew Garrett to add a new
  filesystem that supports larger variables.  Please consider
  backporting this (as an SRU) to both quantal and precise.
