* MdeModulePkg VariablePei: Return GetVariable() attr if EFI_BUFFER_TOO_SMALLMichael Kubacki2020-04-071-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2062 This commit makes the behavior for PeiGetVariable() match the following specification-defined behavior. It is now consistent with the DXE/SMM variable driver implementation. The UEFI specification v2.8 Errata A Section 8.2 "GetVariable()" "Attributes" parameter description states: "If not NULL, a pointer to the memory location to return the attributes bitmask for the variable. See 'Related Definitions.' If not NULL, then Attributes is set on output both when EFI_SUCCESS and when EFI_BUFFER_TOO_SMALL is returned." The attributes were previously only returned from the implementation in Variable.c on EFI_SUCCESS. They are now returned on EFI_SUCCESS or EFI_BUFFER_TOO_SMALL according to spec.

* MdeModulePkg/Variable: Fix VarErrorFlag RT cache offset calculationMichael Kubacki2020-01-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2457 This commit fixes an offset calculation that is used to write the VarErrorFlag UEFI variable to the UEFI variable runtime cache. Currently a physical address is used instead of an offset. This commit changes the offset to zero with a length of the entire non-volatile variable store so the entire non-volatile variable store buffer in SMRAM (with the variable update modification) is copied to the runtime variable cache. This follows the same pattern used in other SynchronizeRuntimeVariableCache () calls for consistency. * Observable symptom: An exception in SMM will most likely occur due to the invalid memory reference when the VarErrorFlag variable is written. The variable is most commonly written when the UEFI variable store is full. * The issue only occurs when the variable runtime cache is enabled by the following PCD being set to TRUE: gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache Fixes: aab3b9b9a1e5e1f3fa966fb1667fc3e6c47e7706 Cc: Liming Gao <liming.gao@intel.com> Cc: Michael D Kinney <michael.d.kinney@intel.com> Cc: Michael Turner <michael.turner@microsoft.com> Cc: Jian J Wang <jian.j.wang@intel.com> Cc: Hao A Wu <hao.a.wu@intel.com> Signed-off-by: Michael Kubacki <michael.a.kubacki@intel.com> Reviewed-by: Liming Gao <liming.gao@intel.com> Reviewed-by: Jian J Wang <jian.j.wang@intel.com>

* MdeModulePkg/Variable: Fix volatile variable RT cache update logicMichael Kubacki2019-11-151-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2333 During a SetVariable () invocation, UpdateVariable () is called. UpdateVariable () contains logic to determine whether a volatile or non-volatile UEFI variable was set so the corresponding runtime cache can be updated to reflect the change. The current logic simply evaluates Variable->Volatile to determine which runtime cache should be updated. The problem is Variable->Volatile does not always reflect whether a volatile variable is being set. Variable->Volatile is set to TRUE only in the case a pre-existing variable is found in the volatile variable store. Therefore, the value is FALSE when a new volatile variable is written. This change updates the logic to take this into account. If a new variable is written successfully, the Attributes will accurately reflect whether the variable is non-volatile. If a pre-existing variable is modified, the Volatile field will reflect the type of variable (Attributes are not reliable; e.g. 0x0 indicates deletion). * Observable symptom: A volatile variable that was set successfully might return EFI_NOT_FOUND when the variable should be found. * The issue is a regression introduced to the variable services only when the variable runtime cache is enabled by the following PCD being set to TRUE: gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache * The issue was implemented in commit aab3b9b9a1 but the PCD was not set to TRUE by default enabling the issue until commit e07b7d024a.

When the Runtime Service GetVariable() is invoked, a Runtime DXE cache is used instead of triggering an SMI to VariableSmm. This can improve overall system performance by servicing variable read requests without rendezvousing all cores into SMM. The runtime cache can be disabled with by setting the FeaturePCD gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache to FALSE. If the PCD is set to FALSE, the runtime cache will not be used and an SMI will be triggered for Runtime Service GetVariable () and GetNextVariableName () invocations. The following are important points regarding the behavior of the variable drivers when the variable runtime cache is enabled. 1. All of the non-volatile storage contents are loaded into the cache upon driver load. This one time load operation from storage is preferred as opposed to building the cache on demand. An on- demand cache would require a fallback SMI to load data into the cache as variables are requested. 2. SetVariable () requests will continue to always trigger an SMI. This occurs regardless of whether the variable is volatile or non-volatile. 3. Both volatile and non-volatile variables are cached in a runtime buffer. As is the case in the current EDK II variable driver, they continue to be cached in separate buffers. 4. The cache in Runtime DXE and SMM are intended to be exact copies of one another. All SMM variable accesses only return data from the SMM cache. The runtime caches are only updated after the variable I/O operation is successful in SMM. The runtime caches are only updated from SMM. 5. Synchronization mechanisms are in place to ensure the runtime cache content integrity with the SMM cache. These may result in updates to runtime cache that are the same in content but different in offset and size from updates to the SMM cache. When using SMM variables with runtime cache enabled, two caches will now be present. 1. "Runtime Cache" - Maintained in VariableSmmRuntimeDxe. Used to service Runtime Services GetVariable () and GetNextVariableName () callers. 2. "SMM Cache" - Maintained in VariableSmm to service SMM GetVariable () and GetNextVariableName () callers. a. This cache is retained so SMM modules do not operate on data outside SMRAM. Because a race condition can occur if an SMI occurs during the execution of runtime code reading from the runtime cache, a runtime cache read lock is introduced that explicitly moves pending updates from SMM to the runtime cache if an SMM update occurs while the runtime cache is locked. Note that it is not expected a Runtime services call will interrupt SMM processing since all CPU cores rendezvous in SMM. It is possible to view UEFI variable read and write statistics by setting the gEfiMdeModulePkgTokenSpaceGuid.PcdVariableCollectStatistics FeaturePcd to TRUE and using the VariableInfo UEFI application in MdeModulePkg to dump variable statistics to the console. By doing so, a user can view the number of GetVariable () hits from the Runtime DXE variable driver (Runtime Cache hits) and the SMM variable driver (SMM Cache hits). SMM Cache hits for GetVariable () will occur when SMM modules invoke GetVariable ().

| | | | | | | | | | | | | | | | | | | | | | For now, PlatformRecovery doesn't work if OsIndications variable doesn't exist, which is wrong. According to the UEFI specification section 3.4.1 and 3.4.2, if processing of BootOrder does not result in success, the OsRecovery and PlatformRecovery options should still be processed regardless of the existence of the OsIndications variable. Therefore, update the code to check PcdPlatformRecoverySupport instead of the value of OsIndications variable (PlatformRecovery) to fix this issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1525 The patch is to merge multiple FMP instances into single ESRT entry when they have the same GUID. The policy to LastAttemptStatus/LastAttemptVersion of ESRT entry is: If all the LastAttemptStatus are LAST_ATTEMPT_STATUS_SUCCESS, then LastAttemptVersion should be the smallest of LastAttemptVersion. If any of the LastAttemptStatus is not LAST_ATTEMPT_STATUS_SUCCESS, then the LastAttemptVersion/LastAttemptStatus should be the values of the first FMP instance whose LastAttemptStatus is not LAST_ATTEMPT_STATUS_SUCCESS. To detect possible duplicated GUID/HardwareInstance, a table of GUID/HardwareInstance pairs from all the EFI_FIRMWARE_IMAGE_DESCRIPTORs from all FMP instances is built. If a duplicate is found, then generate a DEBUG_ERROR message, generate an ASSERT(), and ignore the duplicate EFI_FIRMWARE_IMAGE_DESCRIPTOR. Add an internal worker function called FmpGetFirmwareImageDescriptor() that retrieves the list of EFI_FIRMWARE_IMAGE_DESCRIPTORs from a single FMP instance and returns the descriptors in an allocated buffer. This function is used to get the descriptors used to build the table of unique GUID/HardwareInstance pairs. It is then used again to generate the ESRT Table from all the EFI_FIRMWARE_IMAGE_DESCRIPTORs from all the FMP instances. 2 passes are performed so the total number of descriptors is known. This allows the correct sized buffers to always be allocated.
