* This is a generic 32 bit "collector" for message digest algorithms.
* Whenever needed it collects input character stream into chunks of
* 32 bit values and invokes a block function that performs actual hash
* calculations.
*
* Porting guide.
*
* Obligatory macros:
*
* DATA_ORDER_IS_BIG_ENDIAN or DATA_ORDER_IS_LITTLE_ENDIAN
* this macro defines byte order of input stream.
* HASH_CBLOCK
* size of a unit chunk HASH_BLOCK operates on.
* HASH_LONG
* has to be at least 32 bit wide.
* HASH_CTX
* context structure that at least contains following
* members:
* typedef struct {
* ...
* HASH_LONG Nl,Nh;
* either {
* HASH_LONG data[HASH_LBLOCK];
* unsigned char data[HASH_CBLOCK];
* };
* unsigned int num;
* ...
* } HASH_CTX;
* data[] vector is expected to be zeroed upon first call to
* HASH_UPDATE.
* HASH_UPDATE
* name of "Update" function, implemented here.
* HASH_TRANSFORM
* name of "Transform" function, implemented here.
* HASH_FINAL
* name of "Final" function, implemented here.
* HASH_BLOCK_DATA_ORDER
* name of "block" function capable of treating *unaligned* input
* message in original (data) byte order, implemented externally.
* HASH_MAKE_STRING
* macro converting context variables to an ASCII hash string.
*
* MD5 example:
*
* #define DATA_ORDER_IS_LITTLE_ENDIAN
*
* #define HASH_LONG MD5_LONG
* #define HASH_CTX MD5_CTX
* #define HASH_CBLOCK MD5_CBLOCK
* #define HASH_UPDATE MD5_Update

* Linux kernel 3.7 added support for server TFO.
* Linux kernel 3.13 enabled TFO by default.
* Linux kernel 4.11 added the TCP_FASTOPEN_CONNECT option.
*
* On FreeBSD:
* FreeBSD 10.3 ~ 11.4 uses a single sysctl for server enable.
* FreeBSD 12.0 and later uses separate sysctls for server and
* client enable.

We need to do this since VMS has the following coding on status codes:
Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
The important thing to know is that odd numbers are considered
good, while even ones are considered errors.
Bits 3-15: actual status number
Bits 16-27: facility number. 0 is considered "unknown"
Bits 28-31: control bits. If bit 28 is set, the shell won't try to
output the message (which, for random codes, just looks ugly)
So, what we do here is to change 0 to 1 to get the default success status,
and everything else is shifted up to fit into the status number field, and
the status is tagged as an error, which is what is wanted here.
Finally, we add the VMS C facility code 0x35a000, because there are some
programs, such as Perl, that will reinterpret the code back to something
POSIX. 'man perlvms' explains it further.
NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
codes (status type = 1). I couldn't disagree more. Fortunately, the
status type doesn't seem to bother Perl.

* QUIC Channel
* ============
*
* A QUIC channel (QUIC_CHANNEL) is an object which binds together all of the
* various pieces of QUIC into a single top-level object, and handles connection
* state which is not specific to the client or server roles. In particular, it
* is strictly separated from the libssl front end I/O API personality layer,
* and is not an SSL object.
*
* The name QUIC_CHANNEL is chosen because QUIC_CONNECTION is already in use,
* but functionally these relate to the same thing (a QUIC connection). The use
* of two separate objects ensures clean separation between the API personality
* layer and common code for handling connections, and between the functionality
* which is specific to clients and which is specific to servers, and the
* functionality which is common to both.
*
* The API personality layer provides SSL objects (e.g. a QUIC_CONNECTION) which
* consume a QUIC channel and implement a specific public API. Things which are
* handled by the API personality layer include emulation of blocking semantics,
* handling of SSL object mode flags like non-partial write mode, etc.
*
* Where the QUIC_CHANNEL is used in a server role, there is one QUIC_CHANNEL
* per connection. In the future a QUIC Channel Manager will probably be defined
* to handle ownership of resources which are shared between connections (e.g.
* demuxers). Since we only use server-side functionality for dummy test servers
* for now, which only need to handle one connection at a time, this is not
* currently modelled.
*
* Synchronisation
* ---------------
*
* To support thread assisted mode, QUIC_CHANNEL can be used by multiple
* threads. **It is the caller's responsibility to ensure that the QUIC_CHANNEL
* is only accessed (whether via its methods or via direct access to its state)
* while the channel mutex is held**, except for methods explicitly marked as
* not requiring prior locking. This is an unchecked precondition.
*
* The instantiator of the channel is responsible for providing a suitable
* mutex which then serves as the channel mutex; see QUIC_CHANNEL_ARGS.

/*
* QUIC Demuxer
* ============
*
* The QUIC connection demuxer is the entity responsible for receiving datagrams
* from the network via a datagram BIO. It parses packet headers to determine
* each packet's destination connection ID (DCID) and hands off processing of
* the packet to the correct QUIC Record Layer (QRL)'s RX side (known as the
* QRX).
*
* A QRX is instantiated per QUIC connection and contains the cryptographic
* resources needed to decrypt QUIC packets for that connection. Received
* datagrams are passed from the demuxer to the QRX via a callback registered
* for a specific DCID by the QRX; thus the demuxer has no specific knowledge of
* the QRX and is not coupled to it.
*
* A connection may have multiple connection IDs associated with it; a QRX
* handles this simply by registering multiple connection IDs with the demuxer
* via multiple register calls.
*
* URX Queue
* ---------
*
* Since the demuxer must handle the initial reception of datagrams from the OS,
* RX queue management for new, unprocessed datagrams is also handled by the
* demuxer.
*
* The demuxer maintains a queue of Unprocessed RX Entries (URXEs), which store
* unprocessed (i.e., encrypted, unvalidated) data received from the network.
* The URXE queue is designed to allow multiple datagrams to be received in a
* single call to BIO_recvmmsg, where supported.
*
* One URXE is used per received datagram. Each datagram may contain multiple
* packets, however, this is not the demuxer's concern. QUIC prohibits different
* packets in the same datagram from containing different DCIDs; the demuxer
* only considers the DCID of the first packet in a datagram when deciding how
* to route a received datagram, and it is the responsibility of the QRX to
* enforce this rule. Packets other than the first packet in a datagram are not
* examined by the demuxer, and the demuxer does not perform validation of
* packet headers other than to the minimum extent necessary to extract the
* DCID; further parsing and validation of packet headers is the responsibility
* of the QRX.
*
* Rather than defining an opaque interface, the URXE structure internals
* are exposed. Since the demuxer is only exposed to other parts of the QUIC
* implementation internals, this poses no problem, and has a number of
* advantages:
*
* - Fields in the URXE can be allocated to support requirements in other
* components, like the QRX, which would otherwise have to allocate extra
* memory corresponding to each URXE.
*
* - Other components, like the QRX, can keep the URXE in queues of its own
* when it is not being managed by the demuxer.
*
* URX Queue Structure
* -------------------
*
* The URXE queue is maintained as a simple doubly-linked list. URXE entries are
* moved between different lists in their lifecycle (for example, from a free
* list to a pending list and vice versa). The buffer into which datagrams are
* received immediately follows this URXE header structure and is part of the
* same allocation.

* Core I/O Reactor Framework
* ==========================
*
* Manages use of async network I/O which the QUIC stack is built on. The core
* mechanic looks like this:
*
* - There is a pollable FD for both the read and write side respectively.
* Readability and writeability of these FDs respectively determines when
* network I/O is available.
*
* - The reactor can export these FDs to the user, as well as flags indicating
* whether the user should listen for readability, writeability, or neither.
*
* - The reactor can export a timeout indication to the user, indicating when
* the reactor should be called (via libssl APIs) regardless of whether
* the network socket has become ready.
*
* The reactor is based around a tick callback which is essentially the mutator
* function. The mutator attempts to do whatever it can, attempting to perform
* network I/O to the extent currently feasible. When done, the mutator returns
* information to the reactor indicating when it should be woken up again:
*
* - Should it be woken up when network RX is possible?
* - Should it be woken up when network TX is possible?
* - Should it be woken up no later than some deadline X?
*
* The intention is that ALL I/O-related SSL_* functions with side effects (e.g.
* SSL_read/SSL_write) consist of three phases:
*
* - Optionally mutate the QUIC machine's state.
* - Optionally tick the QUIC reactor.
* - Optionally mutate the QUIC machine's state.
*
* For example, SSL_write is a mutation (appending to a stream buffer) followed
* by an optional tick (generally expected as we may want to send the data
* immediately, though not strictly needed if transmission is being deferred due
* to Nagle's algorithm, etc.).
*
* SSL_read is also a mutation and in principle does not need to tick the
* reactor, but it generally will anyway to ensure that the reactor is regularly
* ticked by an application which is only reading and not writing.
*
* If the SSL object is being used in blocking mode, SSL_read may need to block
* if no data is available yet, and SSL_write may need to block if buffers
* are full.
*
* The internals of the QUIC I/O engine always use asynchronous I/O. If the
* application desires blocking semantics, we handle this by adding a blocking
* adaptation layer on top of our internal asynchronous I/O API as exposed by
* the reactor interface.

* Blocking I/O Adaptation Layer
* =============================
*
* The blocking I/O adaptation layer implements blocking I/O on top of our
* asynchronous core.
*
* The core mechanism is block_until_pred(), which does not return until pred()
* returns a value other than 0. The blocker uses OS I/O synchronisation
* primitives (e.g. poll(2)) and ticks the reactor until the predicate is
* satisfied. The blocker is not required to call pred() more than once between
* tick calls.
*
* When pred returns a non-zero value, that value is returned by this function.
* This can be used to allow pred() to indicate error conditions and short
* circuit the blocking process.
*
* A return value of -1 is reserved for network polling errors. Therefore this
* return value should not be used by pred() if ambiguity is not desired. Note
* that the predicate function can always arrange its own output mechanism, for
* example by passing a structure of its own as the argument.
*
* If the SKIP_FIRST_TICK flag is set, the first call to reactor_tick() before
* the first call to pred() is skipped. This is useful if it is known that
* ticking the reactor again will not be useful (e.g. because it has already
* been done).
*
* This function assumes a write lock is held for the entire QUIC_CHANNEL. If
* mutex is non-NULL, it must be a lock currently held for write; it will be
* unlocked during any sleep, and then relocked for write afterwards.
*
* Precondition: mutex is NULL or is held for write (unchecked)
* Postcondition: mutex is NULL or is held for write (unless
* CRYPTO_THREAD_write_lock fails)

* two directions (RX, TX). At any given time, key material is managed for each
* (EL, RX/TX) combination.
*
* Broadly, for a given (EL, RX/TX), the following state machine is applicable:
*
* WAITING_FOR_KEYS --[Provide]--> HAVE_KEYS --[Discard]--> | DISCARDED |
* \-------------------------------------[Discard]--> | |
*
* To transition the RX side of an EL from WAITING_FOR_KEYS to HAVE_KEYS, call
* ossl_qrx_provide_secret (for the INITIAL EL, use of
* ossl_quic_provide_initial_secret is recommended).
*
* Once keys have been provisioned for an EL, you call
* ossl_qrx_discard_enc_level to transition the EL to the DISCARDED state. You
* can also call this function to transition directly to the DISCARDED state
* even before any keys have been provisioned for that EL.
*
* The DISCARDED state is terminal for a given EL; you cannot provide a secret
* again for that EL after reaching it.
*
* Incoming packets cannot be processed and decrypted if they target an EL
* not in the HAVE_KEYS state. However, there is a distinction between
* the WAITING_FOR_KEYS and DISCARDED states:
*
* - In the WAITING_FOR_KEYS state, the QRX assumes keys for the given
* EL will eventually arrive. Therefore, if it receives any packet
* for an EL in this state, it buffers it and tries to process it
* again once the EL reaches HAVE_KEYS.
*
* - In the DISCARDED state, the QRX assumes no keys for the given
* EL will ever arrive again. If it receives any packet for an EL
* in this state, it is simply discarded.
*
* If the user wishes to instantiate a new QRX to replace an old one for
* whatever reason, for example to take over for an already established QUIC
* connection, it is important that all ELs no longer being used (i.e., INITIAL,
* 0-RTT, 1-RTT) are transitioned to the DISCARDED state. Otherwise, the QRX
* will assume that keys for these ELs will arrive in future, and will buffer
* any received packets for those ELs perpetually. This can be done by calling
* ossl_qrx_discard_enc_level for all non-1-RTT ELs immediately after
* instantiating the QRX.
*
* The INITIAL EL is not setup automatically when the QRX is instantiated. This
* allows the caller to instead discard it immediately after instantiation of
* the QRX if it is not needed, for example if the QRX is being instantiated to
* take over handling of an existing connection which has already passed the
* INITIAL phase. This avoids the unnecessary derivation of INITIAL keys where
* they are not needed. In the ordinary case, ossl_quic_provide_initial_secret
* should be called immediately after instantiation.

* enc_level is a QUIC_ENC_LEVEL_* value. To initialise the INITIAL encryption
* level, it is recommended to use ossl_quic_provide_initial_secret instead.
*
* You should seek to call this function for a given EL before packets of that
* EL arrive and are processed by the QRX. However, if packets have already
* arrived for a given EL, the QRX will defer processing of them and perform
* processing of them when this function is eventually called for the EL in

/*
* Key Update (RX)
* ===============
*
* Key update on the RX side is a largely but not entirely automatic process.
*
* Key update is initially triggered by receiving a 1-RTT packet with a
* different Key Phase value. This could be caused by an attacker in the network
* flipping random bits, therefore such a key update is tentative until the
* packet payload is successfully decrypted and authenticated by the AEAD with
* the 'next' keys. These 'next' keys then become the 'current' keys and the
* 'current' keys then become the 'previous' keys. The 'previous' keys must be
* kept around temporarily as some packets may still be in flight in the network
* encrypted with the old keys. If the old Key Phase value is X and the new Key
* Phase Value is Y (where obviously X != Y), this creates an ambiguity as any
* new packet received with a KP of X could either be an attempt to initiate yet
* another key update right after the last one, or an old packet encrypted
* before the key update.
*
* RFC 9001 provides some guidance on handling this issue:
*
* Strategy 1:
* Three keys, disambiguation using packet numbers
*
* "A recovered PN that is lower than any PN from the current KP uses the
* previous packet protection keys; a recovered PN that is higher than any
* PN from the current KP requires use of the next packet protection
* keys."
*
* Strategy 2:
* Two keys and a timer
*
* "Alternatively, endpoints can retain only two sets of packet protection
* keys, swapping previous keys for next after enough time has passed to
* allow for reordering in the network. In this case, the KP bit alone can
* be used to select keys."
*
* Strategy 2 is more efficient (we can keep fewer cipher contexts around) and
* should cover all actually possible network conditions. It also allows a delay
* after we make the 'next' keys our 'current' keys before we generate new
* 'next' keys, which allows us to mitigate against malicious peers who try to
* initiate an excessive number of key updates.
*
* We therefore model the following state machine:
*
*
* PROVISIONED
* _______________________________
* | |
* UNPROVISIONED --|----> NORMAL <----------\ |------> DISCARDED
* | | | |
* | | | |
* | v | |
* | UPDATING | |
* | | | |
* | | | |
* | v | |
* | COOLDOWN | |
* | | | |
* | | | |
* | \---------------| |
* |_______________________________|
*
*
* The RX starts (once a secret has been provisioned) in the NORMAL state. In
* the NORMAL state, the current expected value of the Key Phase bit is
* recorded. When a flipped Key Phase bit is detected, the RX attempts to
* decrypt and authenticate the received packet with the 'next' keys rather than
* the 'current' keys. If (and only if) this authentication is successful, we
* move to the UPDATING state. (An attacker in the network could flip
* the Key Phase bit randomly, so it is essential we do nothing until AEAD
* authentication is complete.)
*
* In the UPDATING state, we know a key update is occurring and record
* the new Key Phase bit value as the newly current value, but we still keep the
* old keys around so that we can still process any packets which were still in
* flight when the key update was initiated. In the UPDATING state, a
* Key Phase bit value different to the current expected value is treated not as
* the initiation of another key update, but a reference to our old keys.
*
* Eventually we will be reasonably sure we are not going to receive any more
* packets with the old keys. At this point, we can transition to the COOLDOWN
* state. This transition occurs automatically after a certain amount of time;
* RFC 9001 recommends it be the PTO interval, which relates to our RTT to the
* peer. The duration also SHOULD NOT exceed three times the PTO to assist with
* maintaining PFS.
*
* In the COOLDOWN phase, the old keys have been securely erased and only one
* set of keys can be used: the current keys. If a packet is received with a Key
* Phase bit value different to the current Key Phase Bit value, this is treated
* as a request for a Key Update, but this request is ignored and the packet is
* treated as malformed. We do this to allow mitigation against malicious peers
* trying to initiate an excessive number of Key Updates. The timeout for the
* transition from UPDATING to COOLDOWN is recommended as adequate for
* this purpose in itself by the RFC, so the normal additional timeout value for
* the transition from COOLDOWN to normal is zero (immediate transition).
*
* A summary of each state:
*
* Epoch Exp KP Uses Keys KS0 KS1 If Non-Expected KP Bit
* ----- ------ --------- ------ ----- ----------------------
* NORMAL 0 0 Keyset 0 Gen 0 Gen 1 → UPDATING
* UPDATING 1 1 Keyset 1 Gen 0 Gen 1 Use Keyset 0
* COOLDOWN 1 1 Keyset 1 Erased Gen 1 Ignore Packet (*)
*
* NORMAL 1 1 Keyset 1 Gen 2 Gen 1 → UPDATING
* UPDATING 2 0 Keyset 0 Gen 2 Gen 1 Use Keyset 1
* COOLDOWN 2 0 Keyset 0 Gen 2 Erased Ignore Packet (*)
*
* (*) Actually implemented by attempting to decrypt the packet with the
* wrong keys (which ultimately has the same outcome), as recommended
* by RFC 9001 to avoid creating timing channels.
*
* Note that the key material for the next key generation ("key epoch") is
* always kept in the NORMAL state (necessary to avoid side-channel attacks).
* This material is derived during the transition from COOLDOWN to NORMAL.
*
* Note that when a peer initiates a Key Update, we MUST also initiate a Key
* Update as per the RFC. The caller is responsible for detecting this condition
* and making the necessary calls to the TX side by detecting changes to the
* return value of ossl_qrx_get_key_epoch().
*
* The above states (NORMAL, UPDATING, COOLDOWN) can themselves be
* considered substates of the PROVISIONED state. Providing a secret to the QRX
* for an EL transitions from UNPROVISIONED, the initial state, to PROVISIONED
* (NORMAL). Dropping key material for an EL transitions from whatever the
* current substate of the PROVISIONED state is to the DISCARDED state, which is
* the terminal state.
*
* Note that non-1RTT ELs cannot undergo key update, therefore a non-1RTT EL is
* always in the NORMAL substate if it is in the PROVISIONED state.

* of the stream and 0 otherwise. hdr->stream_id is not set; the caller must set
* it.
*
* The caller is not obligated to send all of the data. If the caller does not
* send all of the data, the caller must reduce hdr->len before serializing the
* header structure and must ensure that hdr->is_fin is cleared.
*
* hdr->has_explicit_len is always set. It is the caller's responsibility to
* clear this if it wants to use the optimization of omitting the length field,
* as only the caller can know when this optimization can be performed.
*
* *num_iov must be set to the size of the iov array at call time. When this
* function returns successfully, it is updated to the number of iov entries
* which have been written.
*
* The stream data may be split across up to two IOVs due to internal ring
* buffer organisation. The sum of the lengths of the IOVs and the value written
* to hdr->len will always match. If the caller decides to send less than
* hdr->len of stream data, it must adjust the IOVs accordingly. This may be
* done by updating hdr->len and then calling the utility function
* ossl_quic_sstream_adjust_iov().
*
* After committing one or more bytes returned by ossl_quic_sstream_get_stream_frame to a
* packet, call ossl_quic_sstream_mark_transmitted with the inclusive range of logical
* byte numbers of the transmitted bytes (i.e., hdr->offset, hdr->offset +
* hdr->len - 1). If you do not call ossl_quic_sstream_mark_transmitted, the next call to
* ossl_quic_sstream_get_stream_frame will return the same data (or potentially the same
* and more, if more data has been appended by the application).
*
* It is the caller's responsibility to clamp the length of data which this
* function indicates is available according to other concerns, such as
* stream-level flow control, connection-level flow control, or the applicable
* maximum datagram payload length (MDPL) for a packet under construction.
*
* The skip argument can usually be given as zero. If it is non-zero, this
* function outputs a range which would be output if it were called again after
* calling ossl_quic_sstream_mark_transmitted() with the returned range, repeated 'skip'
* times, and so on. This may be useful for callers which wish to enumerate
* available stream frames and batch their calls to ossl_quic_sstream_mark_transmitted at
* a later time.
*
* On success, this function will never write *num_iov with a value other than
* 0, 1 or 2. A *num_iov value of 0 can only occurs when hdr->is_fin is set (for
* example, when a stream is closed after all existing data has been sent, and
* without sending any more data); otherwise the function returns 0 as there is
* nothing useful to report.

* QUIC Thread Assisted Functionality
* ==================================
*
* Where OS threading support is available, QUIC can optionally support a thread
* assisted mode of operation. The purpose of this mode of operation is to
* ensure that assorted timeout events which QUIC expects to be handled in a
* timely manner can be handled without the application needing to ensure that
* SSL_tick() is called on time. This is not needed if the application always
* has a call blocking to SSL_read() or SSL_write() (or another I/O function) on
* a QUIC SSL object, but if the application goes for long periods of time
* without making any such call to a QUIC SSL object, libssl cannot ordinarily
* guarantee that QUIC timeout events will be serviced in a timely fashion.
* Thread assisted mode is therefore of use to applications which do not always
* have an ongoing call to an I/O function on a QUIC SSL object but also do not
* want to have to arrange periodic ticking.
*
* A consequence of this is that the intrusiveness of thread assisted mode upon
* the general architecture of our QUIC engine is actually fairly limited and
* amounts to an automatic ticking of the QUIC engine when timeouts expire,
* synchronised correctly with an application's own threads using locking.
