[Bug 1934780] Please test proposed package

[Łukasz Zemczak]

Hello Alfonso, or anyone else affected,

Accepted shim into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/shim/15.4-0ubuntu7 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
xenial to verification-done-xenial. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-xenial. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [Impact]
  Systems that do not support QueryVariableInfo() EFI function fail to boot.

  [Test plan]
  Would be good to get this checked on the Mellanox BF1 SmartNIC on one release (shim is binary copied)

  [Where problems could occur]
  it might still fail to mirror variables on those platforms. Code looks like the variable could be uninitialized on error case, but it's actually set inside the call to 0 so that's good.

  [Original bug report]
