A testing framework for the EFI API is provided. It can be executed with the 'bootefi selftest' command. It is coded in a way that at a later stage we may turn it into a standalone EFI application. The current build system does not allow this yet. All tests use a driver model and are run in three phases: setup, execute, teardown. A test may be setup and executed at boottime, it may be setup at boottime and executed at runtime, or it may be setup and executed at runtime. After executing all tests the system is reset.

config CMD_IOTRACE
|
|
bool "iotrace - Support for tracing I/O activity"
|

help
|
|
Provides an 'iotrace' command which supports recording I/O reads and
|
|
writes in a trace buffer in memory . It also maintains a checksum
|
|
of the trace records (even if space is exhausted) so that the
|
|
sequence of I/O accesses can be verified.
|
|
|
|
When debugging drivers it is useful to see what I/O accesses were
|
|
done and in what order.
|
|
|
|
Even if the individual accesses are of little interest it can be
|
|
useful to verify that the access pattern is consistent each time
|
|
an operation is performed. In this case a checksum can be used to
|
|
characterise the operation of a driver. The checksum can be compared
|
|
across different runs of the operation to verify that the driver is
|
|
working properly.
|
|
|
|
In particular, when performing major refactoring of the driver, where
|
|
the access pattern should not change, the checksum provides assurance
|
|
that the refactoring work has not broken the driver.
|
|
|
|
This works by sneaking into the io.h heder for an architecture and
|
|
redirecting I/O accesses through iotrace's tracing mechanism.
|
|
|
|
For now no commands are provided to examine the trace buffer. The
|
|
format is fairly simple, so 'md' is a reasonable substitute.
|
|
|
|
Note: The checksum feature is only useful for I/O regions where the
|
|
contents do not change outside of software control. Where this is not
|
|
suitable you can fall back to manually comparing the addresses. It
|
|
might be useful to enhance tracing to only checksum the accesses and
|
|
not the data read/written.

|
|
help
|
|
This provides a means to encrypt and decrypt data using the AES
|
|
(Advanced Encryption Standard). This algorithm uses a symetric key
|
|
and is widely used as a streaming cipher. Different key lengths are
|
|
supported by the algorithm but this command only supports 128 bits
|
|
at present.

config CMD_BLOB
|
|
bool "Enable the 'blob' command"
|
|
help
|
|
This is used with the Freescale secure boot mechanism.
|
|
|
|
Freescale's SEC block has built-in Blob Protocol which provides
|
|
a method for protecting user-defined data across system power
|
|
cycles. SEC block protects data in a data structure called a Blob,
|
|
which provides both confidentiality and integrity protection.
|
|
|
|
Encapsulating data as a blob
|
|
Each time that the Blob Protocol is used to protect data, a
|
|
different randomly generated key is used to encrypt the data.
|
|
This random key is itself encrypted using a key which is derived
|
|
from SoC's non-volatile secret key and a 16 bit Key identifier.
|
|
The resulting encrypted key along with encrypted data is called a
|
|
blob. The non-volatile secure key is available for use only during
|
|
secure boot.
|
|
|
|
During decapsulation, the reverse process is performed to get back
|
|
the original data.
|
|
|
|
Sub-commands:
|
|
blob enc - encapsulating data as a cryptgraphic blob
|
|
blob dec - decapsulating cryptgraphic blob to get the data
|
|
|
|
Syntax:
|
|
|
|
blob enc src dst len km
|
|
|
|
Encapsulate and create blob of data $len bytes long
|
|
at address $src and store the result at address $dst.
|
|
$km is the 16 byte key modifier is also required for
|
|
generation/use as key for cryptographic operation. Key
|
|
modifier should be 16 byte long.
|
|
|
|

|
Decapsulate the blob of data at address $src and

|
|
correctly. The tests cover initialisation, non-volatile RAM, extend,
|

|
tests pass correctly on Infineon TPMs but may need to be adjusted
|
|
for other devices.
