MdeModulePkg: Align RuntimeDxe function headers with UEFI return values

2024-02-09T22:16:32+00:00

RuntimeDxe is used to back the runtime services time functions, so align the description of the function return values with the defined values for these services as described in UEFI Spec 2.10.

MdeModulePkg/Variable: Merge variable header + data update into one step

2023-11-29T01:45:25+00:00

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4597 When creating a new variable, skip marking VAR_HEADER_VALID_ONLY so that variable header + data update can be merged into one flash write. This will greatly reduce the time taken for updating a variable and thus increase performance. Removing VAR_HEADER_VALID_ONLY marking doesn't have any function impact since it's not used by current code to detect variable header + data corruption.

MdeModulePkg/VariablePolicy: Add more granular variable policy querying

2023-10-31T14:40:50+00:00

Introduces two new APIs to EDKII_VARIABLE_POLICY_PROTOCOL: 1. GetVariablePolicyInfo() 2. GetLockOnVariableStateVariablePolicyInfo() These allow a caller to retrieve policy information associated with a UEFI variable given the variable name and vendor GUID. GetVariablePolicyInfo() - Returns the variable policy applied to the UEFI variable. If the variable policy is applied toward an individual UEFI variable, that name can optionally be returned. GetLockOnVariableStateVariablePolicyInfo() - Returns the Lock on Variable State policy applied to the UEFI variable. If the Lock on Variable State policy is applied to a specific variable name, that name can optionally be returned. These functions can be useful for a variety of purposes such as auditing, testing, and functional flows. Also fixed some variable name typos in code touched by the changes.

MdeModulePkg/Variable: TcgMorLockSmm Key Mismatch changes lock state

2023-07-10T12:24:59+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4410 Inside TcgMorLockSmm.c, the SetVariableCheckHandlerMorLock() function contains a scenario to prevent a possible dictionary attack on the MorLock Key in accordance with the TCG Platform Reset Mitigation Spec v1.10. The mechanism to prevent this attack must also change the MorLock Variable Value to 0x01 to indicate Locked Without Key. ASSERT_EFI_ERROR is added for error visibility since SetMorLockVariable returns a status code Cc: Jian J Wang Cc: Liming Gao Signed-off-by: Abhi Singh Acked-by: Michael Kubacki Reviewed-by: Liming Gao

MdeModulePkg: Variable: Introduce MM based variable read service in PEI

MdeModulePkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__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. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel
