/*
* OSSL_TFO_SYSCTL is used to determine if TFO is supported by
* this kernel, and if supported, if it is enabled. This is more of
* a problem on FreeBSD 10.3 ~ 11.4, where TCP_FASTOPEN was defined,
* but not enabled by default in the kernel, and only for the server.
* Linux does not have sysctlbyname(), and the closest equivalent
* is to go into the /proc filesystem, but I'm not sure it's
* worthwhile.
*
* On MacOS and Linux:
* These operating systems use a single parameter to control TFO.
* The OSSL_TFO_CLIENT_FLAG and OSSL_TFO_SERVER_FLAGS are used to
* determine if TFO is enabled for the client and server respectively.
*
* OSSL_TFO_CLIENT_FLAG = 1 = client TFO enabled
* OSSL_TFO_SERVER_FLAG = 2 = server TFO enabled
*
* Such that:
* 0 = TFO disabled
* 3 = server and client TFO enabled
*
* macOS 10.14 and later support TFO.
* Linux kernel 3.6 added support for client TFO.
* 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.
*
* Some options are purposely NOT defined per-platform
*
* OSSL_TFO_SYSCTL
* Defined as a sysctlbyname() option to determine if
* TFO is enabled in the kernel (macOS, FreeBSD)
*
* OSSL_TFO_SERVER_SOCKOPT
* Defined to indicate the socket option used to enable
* TFO on a server socket (all)
*
* OSSL_TFO_SERVER_SOCKOPT_VALUE
* Value to be used with OSSL_TFO_SERVER_SOCKOPT
*
* OSSL_TFO_CONNECTX
* Use the connectx() function to make a client connection
* (macOS)
*
* OSSL_TFO_CLIENT_SOCKOPT
* Defined to indicate the socket option used to enable
* TFO on a client socket (FreeBSD, Linux 4.14 and later)
*
* OSSL_TFO_SENDTO
* Defined to indicate the sendto() message type to
* be used to initiate a TFO connection (FreeBSD,
* Linux pre-4.14)
*
* OSSL_TFO_DO_NOT_CONNECT
* Defined to skip calling connect() when creating a
* client socket (macOS, FreeBSD, Linux pre-4.14)

* 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)

* Secret Management
* =================
*
* A QRX has several encryption levels (Initial, Handshake, 0-RTT, 1-RTT) and
* 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.
*/
/*
* Provides a secret to the QRX, which arises due to an encryption level change.
* 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
* question.
*
* suite_id is a QRL_SUITE_* value which determines the AEAD function used for
* the QRX.
*
* The secret passed is used directly to derive the "quic key", "quic iv" and
* "quic hp" values.
*
* secret_len is the length of the secret buffer in bytes. The buffer must be
* sized correctly to the chosen suite, else the function fails.
*
* This function can only be called once for a given EL, except for the INITIAL
* EL, which can need rekeying when a connection retry occurs. Subsequent calls
* for non-INITIAL ELs fail, as do calls made after a corresponding call to
* ossl_qrx_discard_enc_level for that EL. The secret for a non-INITIAL EL
* cannot be changed after it is set because QUIC has no facility for

/*
* 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.
*/

* - if qtx is non-NULL, provides the appropriate secret to it.
*
* If both qrx and qtx are NULL, this is a no-op. This function is equivalent to
* making the appropriate calls to ossl_qrx_provide_secret() and
* ossl_qtx_provide_secret().
*
* It is possible to use a QRX or QTX without ever calling this, for example if
* there is no desire to handle INITIAL packets (e.g. if a QRX/QTX is
* instantiated to succeed a previous QRX/QTX and handle a connection which is
* already established). However in this case you should make sure you call
* ossl_qrx_discard_enc_level(); see the header for that function for more
* details. Calling ossl_qtx_discard_enc_level() is not essential but could
* protect against programming errors.

* data which can be written to a stream is not infinite and to allow the
* caller to manifest backpressure conditions to the user.
*
* The QUIC_SSTREAM is instantiated once for every stream with a send component
* (i.e., for a unidirectional send stream or for the send component of a
* bidirectional stream).
*
* Note: The terms 'TX' and 'RX' are used when referring to frames, packets and

* transmitted. is_fin is set to 1 if hdr->offset + hdr->len is the final size
* 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

* The stream's XSO has been deleted. Pending GC.
*
* Here is how stream deletion works:
*
* - A QUIC_STREAM cannot be deleted until it is neither in the accept
* queue nor has an associated XSO. This condition occurs when and only
* when deleted is true.
*
* - Once this is the case (i.e., no user-facing API object exposing the
* stream), we can delete the stream once we determine that all of our
* protocol obligations requiring us to keep the QUIC_STREAM around have
* been met.
*
* The following frames relate to the streams layer for a specific
* stream:
*
* STREAM
*
* RX Obligations:
* Ignore for a deleted stream.
*
* (This is different from our obligation for a
* locally-initiated stream ID we have not created yet,
* which we must treat as a protocol error. This can be
* distinguished via a simple monotonic counter.)
*
* TX Obligations:
* None, once we've decided to (someday) delete the stream.
*
* STOP_SENDING
*
* We cannot delete the stream until we have finished informing
* the peer that we are not going to be listening to it
* anymore.
*
* RX Obligations:
* When we delete a stream we must have already had a FIN
* or RESET_STREAM we transmitted acknowledged by the peer.
* Thus we can ignore STOP_SENDING frames for deleted
* streams (if they occur, they are probably just
* retransmissions).
*
* TX Obligations:
* _Acknowledged_ receipt of a STOP_SENDING frame by the
* peer (unless the peer's send part has already FIN'd).
*
* RESET_STREAM
*
* We cannot delete the stream until we have finished informing
* the peer that we are not going to be transmitting on it
* anymore.
*
* RX Obligations:
* This indicates the peer is not going to send any more
* data on the stream. We don't need to care about this
* since once a stream is marked for deletion we don't care
* about any data it does send. We can ignore this for
* deleted streams. The important criterion is that the
* peer has been successfully delivered our STOP_SENDING
* frame.
*
* TX Obligations:
* _Acknowledged_ receipt of a RESET_STREAM frame or FIN by
* the peer.
*
* MAX_STREAM_DATA
*
* RX Obligations:
* Ignore. Since we are not going to be sending any more
* data on a stream once it has been marked for deletion,
* we don't need to care about flow control information.
*
* TX Obligations:
* None.
*
* In other words, our protocol obligation is simply:
*
* - either:
* - the peer has acknowledged receipt of a STOP_SENDING frame sent
* by us; -or-
* - we have received a FIN and all preceding segments from the peer
*
* [NOTE: The actual criterion required here is simply 'we have
* received a FIN from the peer'. However, due to reordering and
* retransmissions we might subsequently receive non-FIN segments
* out of order. The FIN means we know the peer will stop
* transmitting on the stream at *some* point, but by sending
* STOP_SENDING we can avoid these needless retransmissions we
* will just ignore anyway. In actuality we could just handle all
* cases by sending a STOP_SENDING. The strategy we choose is to
* only avoid sending a STOP_SENDING and rely on a received FIN
* when we have received all preceding data, as this makes it
* reasonably certain no benefit would be gained by sending
* STOP_SENDING.]
*
* TODO(QUIC FUTURE): Implement the latter case (currently we
just always do STOP_SENDING).
*
* and;
*
* - we have drained our send stream (for a finished send stream)
* and got acknowledgement all parts of it including the FIN, or
* sent a RESET_STREAM frame and got acknowledgement of that frame.
*
* Once these conditions are met, we can GC the QUIC_STREAM.

* 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.
