Subject: [PATCH] smm_gateway: GetNextVariableName Fix
|
||
|
|
|
||
|
|
GetNextVariableName() should return EFI_BUFFER_TOO_SMALL
|
||
|
|
when NameSize is smaller than the actual NameSize. It
|
||
|
|
currently returns EFI_BUFFER_OUT_OF_RESOURCES due to setting
|
||
|
|
max_name_len incorrectly. This fixes max_name_len error by
|
||
|
|
replacing it with actual NameSize request by u-boot.
|
||
|
|
|
||
|
|
