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

[Luis Henriques]

This bug is awaiting verification that the kernel for Quantal in
-proposed solves the problem (3.5.0-18.29). Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-quantal' to 'verification-done-quantal'.

If verification is not done by one week from today, this fix will be
dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

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.
