/**
* \file mps_reader.h
*
* \brief This file defines reader objects, which together with their
* sibling writer objects form the basis for the communication
* between the various layers of the Mbed TLS messaging stack,
* as well as the communication between the messaging stack and
* the (D)TLS handshake protocol implementation.
*
* Readers provide a means of transferring incoming data from
* a 'producer' providing it in chunks of arbitrary size, to
* a 'consumer' which fetches and processes it in chunks of
* again arbitrary, and potentially different, size.
*
* Readers can thus be seen as datagram-to-stream converters,
* and they abstract away the following two tasks from the user:
* 1. The pointer arithmetic of stepping through a producer-
* provided chunk in smaller chunks.
* 2. The merging of incoming data chunks in case the
* consumer requests data in larger chunks than what the
* producer provides.
*
* The basic abstract flow of operation is the following:
* - Initially, the reader is in 'producing mode'.
* - The producer hands an incoming data buffer to the reader,
* moving it from 'producing' to 'consuming' mode.
* - The consumer subsequently fetches and processes the buffer
* content. Once that's done -- or partially done and a consumer's
* request can't be fulfilled -- the producer revokes the reader's
* access to the incoming data buffer, putting the reader back to
* producing mode.
* - The producer subsequently gathers more incoming data and hands
* it to the reader until it switches back to consuming mode
* if enough data is available for the last consumer request to
* be satisfiable.
* - Repeat the above.
*
* The abstract states of the reader from the producer's and
* consumer's perspective are as follows:
*
* - From the perspective of the consumer, the state of the
* reader consists of the following:
* - A byte stream representing (concatenation of) the data
* received through calls to mbedtls_mps_reader_get(),
* - A marker within that byte stream indicating which data
* can be considered processed, and hence need not be retained,
* when the reader is passed back to the producer via
* mbedtls_mps_reader_reclaim().
* The marker is set via mbedtls_mps_reader_commit()
* which places it at the end of the current byte stream.
* The consumer need not be aware of the distinction between consumer
* and producer mode, because it only interfaces with the reader
* when the latter is in consuming mode.
*
* - From the perspective of the producer, the reader's state is one of:
* - Attached: The reader is in consuming mode.
* - Unset: No incoming data buffer is currently managed by the reader,
* and all previously handed incoming data buffers have been
* fully processed. More data needs to be fed into the reader
* via mbedtls_mps_reader_feed().
*
* - Accumulating: No incoming data buffer is currently managed by the
* reader, but some data from the previous incoming data
* buffer hasn't been processed yet and is internally
* held back.
* The Attached state belongs to consuming mode, while the Unset and
* Accumulating states belong to producing mode.
*
* Transitioning from the Unset or Accumulating state to Attached is
* done via successful calls to mbedtls_mps_reader_feed(), while
* transitioning from Attached to either Unset or Accumulating (depending
* on what has been processed) is done via mbedtls_mps_reader_reclaim().
*
* The following diagram depicts the producer-state progression:
*
* +------------------+ reclaim
* | Unset +<-------------------------------------+ get
* +--------|---------+ | +------+
* | | | |
* | | | |
* | feed +---------+---+--+ |
* +--------------------------------------> <---+
* | Attached |
* +--------------------------------------> <---+
* | feed, enough data available +---------+---+--+ |
* | to serve previous consumer request | | |
* | | | |
* +--------+---------+ | +------+
* +----> Accumulating |<-------------------------------------+ commit
* | +---+--------------+ reclaim, previous read request
* | | couldn't be fulfilled
* | |
* +--------+
* feed, need more data to serve
* previous consumer request
* |
* |
* producing mode | consuming mode

* This function creates a HkdfLabel structure used in the TLS 1.3 key schedule.

* opaque context<0..255>; // Usually a communication transcript hash

*
* Parameters:
* - desired_length: Length of expanded key material
* Even though the standard allows expansion to up to
* 2**16 Bytes, TLS 1.3 never uses expansion to more than
* 255 Bytes, so we require `desired_length` to be at most
* 255. This allows us to save a few Bytes of code by
* hardcoding the writing of the high bytes.
* - (label, llen): label + label length, without "tls13 " prefix
* The label length MUST be less than or equal to
* MBEDTLS_SSL_TLS1_3_KEY_SCHEDULE_MAX_LABEL_LEN
* It is the caller's responsibility to ensure this.
* All (label, label length) pairs used in TLS 1.3
* can be obtained via MBEDTLS_SSL_TLS1_3_LBL_WITH_LEN().
* - (ctx, clen): context + context length
* The context length MUST be less than or equal to
* MBEDTLS_SSL_TLS1_3_KEY_SCHEDULE_MAX_CONTEXT_LEN
* It is the caller's responsibility to ensure this.
* - dst: Target buffer for HkdfLabel structure,
* This MUST be a writable buffer of size
* at least SSL_TLS1_3_KEY_SCHEDULE_MAX_HKDF_LABEL_LEN Bytes.
* - dlen: Pointer at which to store the actual length of

/*! This flag controls whether the MPS-internal components
* (reader, writer, Layer 1-3) perform validation of the
* expected abstract state at the entry of API calls.
*
* Context: All MPS API functions impose assumptions/preconditions on the
* context on which they operate. For example, every structure has a notion of
* state integrity which is established by `xxx_init()` and preserved by any
* calls to the MPS API which satisfy their preconditions and either succeed,
* or fail with an error code which is explicitly documented to not corrupt
* structure integrity (such as WANT_READ and WANT_WRITE);
* apart from `xxx_init()` any function assumes state integrity as a
* precondition (but usually more). If any of the preconditions is violated,
* the function's behavior is entirely undefined.
* In addition to state integrity, all MPS structures have a more refined
* notion of abstract state that the API operates on. For example, all layers
* have a notion of 'abtract read state' which indicates if incoming data has
* been passed to the user, e.g. through mps_l2_read_start() for Layer 2
* or mps_l3_read() in Layer 3. After such a call, it doesn't make sense to
* call these reading functions again until the incoming data has been
* explicitly 'consumed', e.g. through mps_l2_read_consume() for Layer 2 or
* mps_l3_read_consume() on Layer 3. However, even if it doesn't make sense,
* it's a design choice whether the API should fail gracefully on such
* non-sensical calls or not, and that's what this option is about:
*
* This option determines whether the expected abstract state
* is part of the API preconditions or not: If the option is set,
* then the abstract state is not part of the precondition and is
* thus required to be validated by the implementation. If an unexpected
* abstract state is encountered, the implementation must fail gracefully
* with error #MBEDTLS_ERR_MPS_OPERATION_UNEXPECTED.
* Conversely, if this option is not set, then the expected abstract state
* is included in the preconditions of the respective API calls, and
* an implementation's behaviour is undefined if the abstract state is
* not as expected.
*
* For example: Enabling this makes mps_l2_read_done() fail if
* no incoming record is currently open; disabling this would
* lead to undefined behavior in this case.
*
* Comment this to remove state validation.

/*
* GENERAL NOTE ON CODING STYLE
*
* The following code intentionally separates memory loads
* and stores from other operations (arithmetic or branches).
* This leads to the introduction of many local variables
* and significantly increases the C-code line count, but
* should not increase the size of generated assembly.
*
* The reason for this is twofold:
* (1) It will ease verification efforts using the VST
* (Verified Software Toolchain)
* whose program logic cannot directly reason
* about instructions containing a load or store in
* addition to other operations (e.g. *p = *q or
* tmp = *p + 42).
* (2) Operating on local variables and writing the results
* back to the target contexts on success only
* allows to maintain structure invariants even
* on failure - this in turn has two benefits:
* (2.a) If for some reason an error code is not caught
* and operation continues, functions are nonetheless
* called with sane contexts, reducing the risk
* of dangerous behavior.
* (2.b) Randomized testing is easier if structures
* remain intact even in the face of failing
* and/or non-sensical calls.
* Moreover, it might even reduce code-size because
* the compiler need not write back temporary results
* to memory in case of failure.

* This implementation should never be optimized out by the compiler
*
* This implementation for mbedtls_platform_zeroize() was inspired from Colin
* Percival's blog article at:
*
* http://www.daemonology.net/blog/2014-09-04-how-to-zero-a-buffer.html
*
* It uses a volatile function pointer to the standard memset(). Because the
* pointer is volatile the compiler expects it to change at
* any time and will not optimize out the call that could potentially perform
* other operations on the input buffer instead of just setting it to 0.
* Nevertheless, as pointed out by davidtgoldblatt on Hacker News
* (refer to http://www.daemonology.net/blog/2014-09-05-erratum.html for
* details), optimizations of the following form are still possible:
*
* if( memset_func != memset )
* memset_func( buf, 0, len );
*
* Note that it is extremely difficult to guarantee that
* mbedtls_platform_zeroize() will not be optimized out by aggressive compilers
* in a portable way. For this reason, Mbed TLS also provides the configuration
* option MBEDTLS_PLATFORM_ZEROIZE_ALT, which allows users to configure
* mbedtls_platform_zeroize() to use a suitable implementation for their
* platform and needs.

* Find a suitable parent for child in candidates, or return NULL.
*
* Here suitable is defined as:
* 1. subject name matches child's issuer
* 2. if necessary, the CA bit is set and key usage allows signing certs
* 3. for trusted roots, the signature is correct
* (for intermediates, the signature is checked and the result reported)
* 4. pathlen constraints are satisfied
*
* If there's a suitable candidate which is also time-valid, return the first
* such. Otherwise, return the first suitable candidate (or NULL if there is
* none).
*
* The rationale for this rule is that someone could have a list of trusted
* roots with two versions on the same root with different validity periods.
* (At least one user reported having such a list and wanted it to just work.)
* The reason we don't just require time-validity is that generally there is
* only one version, and if it's expired we want the flags to state that
* rather than NOT_TRUSTED, as would be the case if we required it here.
*
* The rationale for rule 3 (signature for trusted roots) is that users might
* have two versions of the same CA with different keys in their list, and the
* way we select the correct one is by checking the signature (as we don't
* rely on key identifier extensions). (This is one way users might choose to
* handle key rollover, another relies on self-issued certs, see [SIRO].)
*
* Arguments:
* - [in] child: certificate for which we're looking for a parent
* - [in] candidates: chained list of potential parents
* - [out] r_parent: parent found (or NULL)
* - [out] r_signature_is_good: 1 if child signature by parent is valid, or 0
* - [in] top: 1 if candidates consists of trusted roots, ie we're at the top
* of the chain, 0 otherwise
* - [in] path_cnt: number of intermediates seen so far
* - [in] self_cnt: number of self-signed intermediates seen so far
* (will never be greater than path_cnt)
* - [in-out] rs_ctx: context for restarting operations
