** Description changed: + [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] + shim in focal-proposed (shim-signed 1.40.5) is crashing on Mellanox BF1 SmartNIC, showing this trace: >>Start PXE over IPv4.
