| Set the configuration of the underlying inline cryptographic interface. | |
| The SetConfiguration() function allows the user to set the current configuration of the | |
| inline cryptographic interface and should be called before attempting any crypto operations. | |
| This configures the configuration table entries with algorithms, key sizes and keys. Each | |
| configured entry can later be referred to by index at the time of storage transaction. | |
| The configuration table index will refer to the combination ofKeyOwnerGuid, Algorithm, and | |
| CryptoKey. | |
| KeyOwnerGuid identifies the component taking ownership of the entry. It helps components to | |
| identify their own entries, cooperate with other owner components, and avoid conflicts. This | |
| Guid identifier is there to help coordination between cooperating components and not a security | |
| or synchronization feature. The Nil GUID can be used by a component to release use of entry | |
| owned. It is also used to identify potentially available entries (see GetConfiguration). | |
| CryptoKey specifies algorithm-specific key material to use within parameters of selected crypto | |
| capability. | |
| This function is called infrequently typically once, on device start, before IO starts. It | |
| can be called at later times in cases the number of keysused on the drive is higher than what | |
| can be configured at a time or a new key has to be added. | |
| Components setting or changing an entry or entries for a given index or indices must ensure | |
| that IO referencing affected indices is temporarily blocked (run-down) at the time of change. | |
| Indices parameters in each parameter table entry allow to set only a portion of the available | |
| table entries in the crypto module anywhere from single entry to entire table supported. | |
| If corresponding table entry or entries being set are already in use by another owner the call | |
| should be failed and none of the entries should be modified. The interface implementation must | |
| enforce atomicity of this operation (should either succeed fully or fail completely without | |
| modifying state). | |
| Note that components using GetConfiguration command to discover available entries should be | |
| prepared that by the time of calling SetConfiguration the previously available entry may have | |
| become occupied. Such components should be prepared to re-try the sequence of operations. | |
| Alternatively EFI_BLOCK_IO_CRYPTO_INDEX_ANY can be used to have the implementation discover | |
| and allocate available,if any, indices atomically. | |
| An optional ResultingTable pointer can be provided by the caller to receive the newly configured | |
| entries. The array provided by the caller must have at least ConfigurationCount of entries. | |
