2023-04-10MdeModulePkg: Update code to be more C11 compliant by using __func__Rebecca Cran1-2/+2
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout MdeModulePkg.

2021-05-23MdeModulePkg/VariableLock: downgrade compatibility warnings to DEBUG_WARNLaszlo Ersek1-5/+5
Commit a18a9bde36d2 ("MdeModulePkg/Variable/RuntimeDxe: Restore Variable Lock Protocol behavior", 2020-12-15), for bug 3111, added two such sets of debug messages that: (a) are relevant for developers, (b) yet should not necessarily poke end-users, because no functionality suffers in practice. Both message sets are in function VariableLockRequestToLock(): the first is a generic interface deprecation warning; the second is the double-locking situation, which we permit for compatibility (return status EFI_SUCCESS). Both message sets should be emitted with the DEBUG_WARN mask, not the most serious DEBUG_ERROR mask. On some platforms, the serial console carries both terminal traffic, and grave (DEBUG_ERROR-only) log messages. On such platforms, both message sets may be perceived as a nuisance by end-users, as there is nothing they can do, and there's nothing they *should* do -- in practice, nothing malfunctions. (Such a platform is ArmVirtQemu, built with "-D DEBUG_PRINT_ERROR_LEVEL=0x80000000".)

https://bugzilla.tianocore.org/show_bug.cgi?id=3111 The VariableLock shim currently fails if called twice because the underlying Variable Policy engine returns an error if a policy is set on an existing variable. This breaks existing code which expect it to silently pass if a variable is locked multiple times (because it should "be locked"). Refactor the shim to confirm that the variable is indeed locked and then change the error to EFI_SUCCESS and generate a DEBUG_ERROR message so the duplicate lock can be reported in a debug log and removed.
