 To build and execute OP-TEE follow the instructions at
 `OP-TEE build.git`_
 
+There are two different modes for loading the OP-TEE OS. The default mode will
+load it as the BL32 payload during boot, and is the recommended technique for
+platforms to use. There is also another technique that will load OP-TEE OS after
+boot via an SMC call by enabling the option for OPTEE_ALLOW_SMC_LOAD that was
+specifically added for ChromeOS. Loading OP-TEE via an SMC call may be insecure
+depending upon the platform configuration. If using that option, be sure to
+understand the risks involved with allowing the Trusted OS to be loaded this
+way. ChromeOS uses a boot flow where it verifies the signature of the firmware
+before executing it, and then only if the signature is valid will the 'secrets'
+used by the TEE become accessible. The firmware then verifies the signature of
+the kernel using depthcharge, and the kernel verifies the rootfs using
+dm-verity.  The SMC call to load OP-TEE is then invoked immediately after the
+kernel finishes loading and before any attack vectors can be opened up by
+mounting writable filesystems or opening network/device connections. this
+ensures the platform is 'closed' and running signed code through the point where
+OP-TEE is loaded.

+Runtime Security Subsystem (RSS)
+================================
+
+This document focuses on the relationship between the Runtime Security Subsystem
+(RSS) and the application processor (AP). According to the ARM reference design
+the RSS is an independent core next to the AP and the SCP on the same die. It
+provides fundamental security guarantees and runtime services for the rest of
+the system (e.g.: trusted boot, measured boot, platform attestation,
+key management, and key derivation).
+
+At power up RSS boots first from its private ROM code. It validates and loads
+its own images and the initial images of SCP and AP. When AP and SCP are
+released from reset and their initial code is loaded then they continue their
+own boot process, which is the same as on non-RSS systems. Please refer to the
+``RSS documentation`` [1]_ for more details about the RSS boot flow.
+
+The last stage of the RSS firmware is a persistent, runtime component. Much
+like AP_BL31, this is a passive entity which has no periodical task to do and
+just waits for external requests from other subsystems. RSS and other
+subsystems can communicate with each other over message exchange. RSS waits
+in idle for the incoming request, handles them, and sends a response then goes
+back to idle.
+
+RSS communication layer
+-----------------------
+
+The communication between RSS and other subsystems are primarily relying on the
+Message Handling Unit (MHU) module. The number of MHU interfaces between RSS
+and other cores is IMPDEF. Besides MHU other modules also could take part in
+the communication. RSS is capable of mapping the AP memory to its address space.
+Thereby either RSS core itself or a DMA engine if it is present, can move the
+data between memory belonging to RSS or AP. In this way, a bigger amount of data
+can be transferred in a short time.
+
+The MHU comes in pairs. There is a sender and receiver side. They are connected
+to each other. An MHU interface consists of two pairs of MHUs, one sender and
+one receiver on both sides. Bidirectional communication is possible over an
+interface. One pair provides message sending from AP to RSS and the other pair
+from RSS to AP. The sender and receiver are connected via channels. There is an
+IMPDEF number of channels (e.g: 4-16) between a sender and a receiver module.
+
+The RSS communication layer provides two ways for message exchange:
+
+- ``Embedded messaging``: The full message, including header and payload, are
+  exchanged over the MHU channels. A channel is capable of delivering a single
+  word. The sender writes the data to the channel register on its side and the
+  receiver can read the data from the channel on the other side. One dedicated
+  channel is used for signalling. It does not deliver any payload it is just
+  meant for signalling that the sender loaded the data to the channel registers
+  so the receiver can read them. The receiver uses the same channel to signal
+  that data was read. Signalling happens via IRQ. If the message is longer than
+  the data fit to the channel registers then the message is sent over in
+  multiple rounds. Both, sender and receiver allocate a local buffer for the
+  messages. Data is copied from/to these buffers to/from the channel registers.
+- ``Pointer-access messaging``: The message header and the payload are
+  separated and they are conveyed in different ways. The header is sent
+  over the channels, similar to the embedded messaging but the payload is
+  copied over by RSS core (or by DMA) between the sender and the receiver. This
+  could be useful in the case of long messages because transaction time is less
+  compared to the embedded messaging mode. Small payloads are copied by the RSS
+  core because setting up DMA would require more CPU cycles. The payload is
+  either copied into an internal buffer or directly read-written by RSS. Actual
+  behavior depends on RSS setup, whether the partition supports memory-mapped
+  ``iovec``. Therefore, the sender must handle both cases and prevent access to
+  the memory, where payload data lives, while the RSS handles the request.
+
+The RSS communication layer supports both ways of messaging in parallel. It is
+decided at runtime based on the message size which way to transfer the message.

+
+    The RSS communication layer is not prepared for concurrent execution. The
+    current use case only requires message exchange during the boot phase. In
+    the boot phase, only a single core is running and the rest of the cores are
+    in reset.
+
+Message structure
+^^^^^^^^^^^^^^^^^
+A description of the message format can be found in the ``RSS communication
+design`` [2]_ document.
+
+Source files
+^^^^^^^^^^^^
+- RSS comms:  ``drivers/arm/rss``
+- MHU driver: ``drivers/arm/mhu``
+
+
+API for communication over MHU
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The API is defined in these header files:
+
+- ``include/drivers/arm/rss_comms.h``
+- ``include/drivers/arm/mhu.h``
+
+RSS provided runtime services
+-----------------------------
+
+RSS provides the following runtime services:
+
+- ``Measured boot``: Securely store the firmware measurements which were
+  computed during the boot process and the associated metadata (image
+  description, measurement algorithm, etc.). More info on measured boot service
+  in RSS can be found in the ``measured_boot_integration_guide`` [3]_ .
+- ``Delegated attestation``: Query the platform attestation token and derive a
+  delegated attestation key. More info on the delegated attestation service
+  in RSS can be found in the ``delegated_attestation_integration_guide`` [4]_ .
+- ``OTP assets management``: RSS provides access for AP to assets in OTP.
+  These are keys for image signature verification and non-volatile counters
+  for anti-rollback protection. Only RSS has direct access to the OTP. Public
+  keys used by AP during the trusted boot process can be requested from RSS.
+  Furthermore, AP can request RSS to increase a non-volatile counter. Please
+  refer to the ``RSS key management`` [5]_ document for more details.
+
+Runtime service API
+^^^^^^^^^^^^^^^^^^^
+The RSS provided runtime services implement a PSA aligned API. The parameter
+encoding follows the PSA client protocol described in the
+``Firmware Framework for M`` [6]_ document in chapter 4.4. The implementation is
+restricted to the static handle use case therefore only the ``psa_call`` API is
+implemented.

+RSS based Measured Boot
+-----------------------
+
+Measured Boot is the process of cryptographically measuring (computing the hash
+value of a binary) the code and critical data used at boot time. The
+measurement must be stored in a tamper-resistant way, so the security state
+of the device can be attested later to an external party. RSS provides a runtime
+service which is meant to store measurements and associated metadata alongside.
+
+Data is stored in internal SRAM which is only accessible by the secure runtime
+firmware of RSS. Data is stored in so-called measurement slots. A platform has
+IMPDEF number of measurement slots. The measurement storage follows extend
+semantics. This means that measurements are not stored directly (as it was
+taken) instead they contribute to the current value of the measurement slot.
+The extension implements this logic, where ``||`` stands for concatenation:
+
+.. code-block:: bash
+
+    new_value_of_measurement_slot = Hash(old_value_of_measurement_slot || measurement)
+
+Supported hash algorithms: sha-256, sha-512

+                                         bool           lock_measurement);
+
+Measured Boot Metadata
+^^^^^^^^^^^^^^^^^^^^^^
+
+The following metadata can be stored alongside the measurement:
+
+- ``Signer-id``: Mandatory. The hash of the firmware image signing public key.
+- ``Measurement algorithm``: Optional. The hash algorithm which was used to
+  compute the measurement (e.g.: sha-256, etc.).
+- ``Version info``: Optional. The firmware version info (e.g.: 2.7).
+- ``SW type``: Optional. Short text description (e.g.: BL1, BL2, BL31, etc.)
+
+.. Note::
+    Signer-id and version info is not implemented in TF-A yet.
+
+The caller must specify in which measurement slot to extend a certain
+measurement and metadata. A measurement slot can be extended by multiple
+measurements. The default value is IMPDEF. All measurement slot is cleared at
+reset, there is no other way to clear them. In the reference implementation,
+the measurement slots are initialized to 0. At the first call to extend the
+measurement in a slot, the extend operation uses the default value of the
+measurement slot. All upcoming extend operation on the same slot contributes
+to the previous value of that measurement slot.
+
+The following rules are kept when a slot is extended multiple times:
+
+- ``Signer-id`` must be the same as the previous call(s), otherwise a
+  PSA_ERROR_NOT_PERMITTED error code is returned.
+
+- ``Measurement algorithm``: must be the same as the previous call(s),
+  otherwise, a PSA_ERROR_NOT_PERMITTED error code is returned.
+
+In case of error no further action is taken (slot is not locked). If there is
+a valid data in a sub-sequent call then measurement slot will be extended. The
+rest of the metadata is handled as follows when a measurement slot is extended
+multiple times:
+
+- ``SW type``: Cleared.
+- ``Version info``: Cleared.
+
+.. Note::
+
+    Extending multiple measurements in the same slot leads to some metadata
+    information loss. Since RSS is not constrained on special HW resources to
+    store the measurements and metadata, therefore it is worth considering to
+    store all of them one by one in distinct slots. However, they are one-by-one
+    included in the platform attestation token. So, the number of distinct
+    firmware image measurements has an impact on the size of the attestation
+    token.
+
+The allocation of the measurement slot among RSS, Root and Realm worlds is
+platform dependent. The platform must provide an allocation of the measurement
+slot at build time. An example can be found in
+``tf-a/plat/arm/board/tc/tc_bl1_measured_boot.c``
+Furthermore, the memory, which holds the metadata is also statically allocated
+in RSS memory. Some of the fields have a static value (measurement algorithm),
+and some of the values have a dynamic value (measurement value) which is updated
+by the bootloaders when the firmware image is loaded and measured. The metadata
+structure is defined in
+``include/drivers/measured_boot/rss/rss_measured_boot.h``.
+
+.. code-block:: c
+
+    struct rss_mboot_metadata {
+            unsigned int id;
+            uint8_t slot;
+            uint8_t signer_id[SIGNER_ID_MAX_SIZE];
+            size_t  signer_id_size;
+            uint8_t version[VERSION_MAX_SIZE];
+            size_t  version_size;
+            uint8_t sw_type[SW_TYPE_MAX_SIZE];
+            size_t  sw_type_size;
+            bool    lock_measurement;
+    };
+
+Build time config options
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- ``MEASURED_BOOT``: Enable measured boot. It depends on the platform
+  implementation whether RSS or TPM (or both) backend based measured boot is
+  enabled.
+- ``MBOOT_RSS_HASH_ALG``: Determine the hash algorithm to measure the images.
+  The default value is sha-256.

+Delegated Attestation
+---------------------
+
+Delegated Attestation Service was mainly developed to support the attestation
+flow on the ``ARM Confidential Compute Architecture`` (ARM CCA) [7]_.
+The detailed description of the delegated attestation service can be found in
+the ``Delegated Attestation Service Integration Guide`` [4]_ document.
+
+In the CCA use case, the Realm Management Monitor (RMM) relies on the delegated
+attestation service of the RSS to get a realm attestation key and the CCA
+platform token. BL31 does not use the service for its own purpose, only calls
+it on behalf of RMM. The access to MHU interface and thereby to RSS is
+restricted to BL31 only. Therefore, RMM does not have direct access, all calls
+need to go through BL31. The RMM dispatcher module of the BL31 is responsible
+for delivering the calls between the two parties.
+
+.. Note::
+     Currently the connection between the RMM dispatcher and the PSA/RSS layer
+     is not yet implemented. RMM dispatcher just returns hard coded data.

    each level enabling more warning options. Default is 0.
 
+   This option is closely related to the ``E`` option, which enables
+   ``-Werror``.
+
+   - ``W=0`` (default)
+
+     Enables a wide assortment of warnings, most notably ``-Wall`` and
+     ``-Wextra``, as well as various bad practices and things that are likely to
+     result in errors. Includes some compiler specific flags. No warnings are
+     expected at this level for any build.
+
+   - ``W=1``
+
+     Enables warnings we want the generic build to include but are too time
+     consuming to fix at the moment. It re-enables warnings taken out for
+     ``W=0`` builds (a few of the ``-Wextra`` additions). This level is expected
+     to eventually be merged into ``W=0``. Some warnings are expected on some
+     builds, but new contributions should not introduce new ones.
+
+   - ``W=2`` (recommended)
+
+    Enables warnings we want the generic build to include but cannot be enabled
+    due to external libraries. This level is expected to eventually be merged
+    into ``W=0``. Lots of warnings are expected, primarily from external
+    libraries like zlib and compiler-rt, but new controbutions should not
+    introduce new ones.
+
+   - ``W=3``
+
+     Enables warnings that are informative but not necessary and generally too
+     verbose and frequently ignored. A very large number of warnings are
+     expected.
+
+   The exact set of warning flags depends on the compiler and TF-A warning
+   level, however they are all succinctly set in the top-level Makefile. Please
+   refer to the `GCC`_ or `Clang`_ documentation for more information on the

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uint64_t
+    Argument : cpu_context_t *
+    Return   : int
+
+This function is invoked by BL31's exception handler when there is a synchronous
+system register trap caused by access to the RNDR or RNDRRS registers. It allows
+platforms implementing ``FEAT_RNG_TRAP`` and enabling ``ENABLE_FEAT_RNG_TRAP`` to
+emulate those system registers by returing back some entropy to the lower EL.
+
+The first parameter (``uint64_t esr_el3``) contains the content of the ESR_EL3
+syndrome register, which encodes the instruction that was trapped. The interesting
+information in there is the target register (``get_sysreg_iss_rt()``).
+
+The second parameter (``cpu_context_t *ctx``) represents the CPU state in the
+lower exception level, at the time when the execution of the ``mrs`` instruction
+was trapped. Its content can be changed, to put the entropy into the target
+register.
+
+The return value indicates how to proceed:
+
+-  When returning ``TRAP_RET_UNHANDLED`` (-1), the machine will panic.
+-  When returning ``TRAP_RET_REPEAT`` (0), the exception handler will return
+   to the same instruction, so its execution will be repeated.
+-  When returning ``TRAP_RET_CONTINUE`` (1), the exception handler will return
+   to the next instruction.
+
+This function needs to be implemented by a platform if it enables FEAT_RNG_TRAP.

-Boot firmwares are loaded via secure FLASH0 device so ``bl1.bin`` and
-``fip.bin`` should be concatenated to create a ``flash.bin`` that is flashed
-onto secure FLASH0.

+The ``-bios`` option abstracts the loading of raw bare metal binaries into flash
+or ROM memory. QEMU loads the binary into the region corresponding to
+the hardware's entrypoint, from which the binary is executed upon a platform
+"reset". In addition to this, it places the information about the kernel
+provided with option ``-kernel``, and the RamDisk provided with ``-initrd``,
+into the firmware configuration ``fw_cfg``. In this setup, EDK II is responsible
+for extracting and launching these from ``fw_cfg``.
+
+.. note::
+    QEMU may be launched with or without ACPI (``-acpi``/``-no-acpi``). In
+    either case, ensure that the kernel build options are aligned with the
+    parameters passed to QEMU.

+
+This security advisory describes a vulnerability in the X.509 parser used to
+parse boot certificates in TF-A trusted boot: it is possible for a crafted
+certificate to cause an out-of-bounds memory read.
+
+Note that upstream platforms are **not** affected by this. Only downstream
+platforms may be, if (and only if) the interfaces described below are used in a
+different context than seen in upstream code. Details of such context is
+described in the rest of this document.
+
+To fully understand this security advisory, it is recommended to refer to the
+following standards documents:
+
+ - `RFC 5280`_, *Internet X.509 Public Key Infrastructure Certificate and
+   Certificate Revocation List (CRL) Profile*.
+
+ - `ITU-T X.690`_, *ASN.1 encoding rules: Specification of Basic Encoding Rules
+   (BER), Canonical Encoding Rules (CER) and Distinguished Encoding Rules
+   (DER).*
+
+Bug 1: Insufficient certificate validation
+------------------------------------------
+
+The vulnerability lies in the following source file:
+``drivers/auth/mbedtls/mbedtls_x509_parser.c``. By design, ``get_ext()`` does
+not check the return value of the various ``mbedtls_*()`` functions, as
+``cert_parse()`` is assumed to have guaranteed that they will always succeed.
+However, it passes the end of an extension as the end pointer to these
+functions, whereas ``cert_parse()`` passes the end of the ``TBSCertificate``.
+Furthermore, ``cert_parse()`` does not check that the contents of the extension
+have the same length as the extension itself. It also does not check that the
+extension block extends to the end of the ``TBSCertificate``.
+
+This is a problem, as ``mbedtls_asn1_get_tag()`` leaves ``*p`` and ``*len``
+undefined on failure.  In practice, this results in ``get_ext()`` continuing to
+parse at different offsets than were used (and validated) by ``cert_parse()``,
+which means that the in-bounds guarantee provided by ``cert_parse()`` no longer
+holds.  The result is that it is possible for ``get_ext()`` to read memory past
+the end of the certificate.  This could potentially access memory with dangerous
+read side effects, or leak microarchitectural state that could theoretically be
+retrieved through some side-channel attacks as part of a more complex attack.
+
+Bug 2: Missing bounds check in ``auth_nvctr()``
+-----------------------------------------------
+``auth_nvctr()`` does not check that the buffer provided is
+long enough to hold an ``ASN.1 INTEGER``.  Since ``auth_nvctr()`` will only ever
+read 6 bytes, it is possible to read up to 6 bytes past the end of the buffer.
+
+Exploitability Analysis
+-----------------------
+
+Upstream TF-A Code
+~~~~~~~~~~~~~~~~~~
+
+In upstream TF-A code, the only caller of ``auth_nvctr()`` takes its input from
+``get_ext()``, which means that the second bug is exploitable, so is the first.
+Therefore, only the first bug need be considered.
+
+All standard chains of trust provided in TF-A source tree (that is, under
+``drivers/auth/``) require that the certificate's signature has already been
+validated prior to calling ``get_ext()``, or any function that calls ``get_ext()``.
+Platforms taking their chain of trust from a dynamic configuration file (such as
+``fdts/cot_descriptors.dtsi``) are also safe, as signature verification will
+always be done prior to any calls to ``get_ext()`` or ``auth_nvctr()`` in this
+case, no matter the order of the properties in the file.  Therefore, it is not
+possible to exploit this vulnerability pre-authentication in upstream TF-A.
+
+Furthermore, the data read through ``get_ext()`` only
+ever gets used by the authentication framework (``drivers/auth/auth_mod.c``),
+which greatly reduces the range of inputs it will ever receive and thus the
+impact this has. Specifically, the authentication framework uses ``get_ext()``
+in three cases:
+
+ 1. Retrieving a hash from an X.509 certificate to check the integrity of a
+    child certificate (see ``auth_hash()``).
+
+ 2. Retrieving the signature details from an X.509 certificate to check its
+    authenticity and integrity (see ``auth_signature()``).
+
+ 3. Retrieving the security counter value from an X.509 certificate to protect
+    it from unauthorized rollback to a previous version (see ``auth_nvctr()``).
+
+None of these uses authentication framework write to the out-of-bounds memory,
+so no memory corruption is possible.
+
+In summary, there are 2 separate issues - one in ``get_ext()`` and another one
+in ``auth_nvctr()`` - but neither of these can be exploited in the context of
+TF-A upstream code.
+
+Only in the following 2 cases do we expect this vulnerability to be triggerable
+prior to authentication:
+
+ - The platform uses a custom chain of trust which uses the non-volatile counter
+   authentication method (``AUTH_METHOD_NV_CTR``) before the cryptographic
+   authentication method (``AUTH_METHOD_SIG``).
+
+ - The chain of trust uses a custom authentication method that calls
+   ``get_ext()`` before cryptographic authentication.
+
+Custom Image Parsers
+~~~~~~~~~~~~~~~~~~~~
+
+If the platform uses a custom image parser instead of the certificate parser,
+the bug in the certificate parser is obviously not relevant.  The bug in
+``auth_nvctr()`` *may* be relevant, but only if the returned data is:
+
+- Taken from an untrusted source (meaning that it is read prior to
+  authentication).
+
+- Not already checked to be a primitively-encoded ASN.1 tag.
+
+In particular, if the custom image parser implementation wraps a 32-bit integer
+in an ASN.1 ``INTEGER``, it is not affected.
