+
+ ::mEslLayer is the one and only ::ESL_LAYER structure. It connects directly or
+ indirectly to the other data structures. The ESL_LAYER structure has a unique
+ service list for each of the network protocol interfaces.
+
+ ::ESL_SERVICE manages the network interfaces for a given transport type (IP4, TCP4, UDP4, etc.)
+
+ ::ESL_SOCKET manages the activity for a single socket instance. As such, it contains
+ the ::EFI_SOCKET_PROTOCOL structure which the BSD socket library uses as the object
+ reference and the API into the EFI socket library.
+
+ ::ESL_PORT manages the connection with a single instance of the lower layer network.
+ This structure is the socket equivalent of an IP connection or a TCP or UDP port.
+
+ ::ESL_PACKET buffers data for transmit and receive. There are four queues connected
+ to the ::ESL_SOCKET that manage the data:
+ <ul>
+ <li>ESL_SOCKET::pRxPacketListHead - Normal (low) priority receive data</li>
+ <li>ESL_SOCKET::pRxOobPacketListHead - High (out-of-band or urgent) priority receive data</li>
+ <li>ESL_SOCKET::pTxPacketListHead - Normal (low) priority transmit data</li>
+ <li>ESL_SOCKET::pTxOobPacketListHead - High (out-of-band or urgent) priority transmit data</li>
+ </ul>
+ The selection of the transmit queue is controlled by the MSG_OOB flag on the transmit
+ request as well as the socket option SO_OOBINLINE. The receive queue is selected by
+ the URGENT data flag for TCP and the setting of the socket option SO_OOBINLINE.
+
+ Data structure synchronization is done by raising TPL to TPL_SOCKET. Modifying
+ critical elements within the data structures must be done at this TPL. TPL is then
+ restored to the previous level. Note that the code verifies that all callbacks are
+ entering at TPL_SOCKETS for proper data structure synchronization.
+
+ \section PortCloseStateMachine Port Close State Machine
+
+ The port close state machine walks the port through the necessary
+ states to stop activity on the port and get it into a state where
+ the resources may be released. The state machine consists of the
+ following arcs and states:
+
+ <code><pre>
+
+ +--------------------------+
+ | Open |
+ +--------------------------+
+ |
+ | ::EslSocketPortCloseStart
+ V
+ +--------------------------+

+ |

+ +--------------------------+
+ |
+ | ::EslSocketPortClose
+ V
+ +--------------------------+
+ | Closed |
+ +--------------------------+
+
+ </pre></code>
+
+ <ul>
+ <li>Arc: ::EslSocketPortCloseStart - Marks the port as closing and
+ initiates the port close operation</li>
+ <li>State: PORT_STATE_CLOSE_STARTED</li>
+ <li>Arc: ::EslSocketPortCloseTxDone - Waits until all of the transmit
+ operations to complete. After all of the transmits are complete,
+ this routine initiates the network specific close operation by calling
+ through ESL_PROTOCOL_API::pfnPortCloseOp. One such routine is
+ ::EslTcp4PortCloseOp.
+ </li>
+ <li>State: PORT_STATE_CLOSE_TX_DONE</li>
+ <li>Arc: ::EslSocketPortCloseComplete - Called when the close operation is
+ complete. After the transition to PORT_STATE_CLOSE_DONE,
+ this routine calls ::EslSocketRxCancel to abort the pending receive operations.
+ </li>
+ <li>State: PORT_STATE_CLOSE_DONE</li>
+ <li>Arc: ::EslSocketPortCloseRxDone - Waits until all of the receive
+ operation have been cancelled. After the transition to
+ PORT_STATE_CLOSE_RX_DONE, this routine calls ::EslSocketPortClose.
+ </li>
+ <li>State: PORT_STATE_CLOSE_RX_DONE</li>
+ <li>Arc: ::EslSocketPortClose - This routine discards any receive buffers
+ using a network specific support routine via ESL_PROTOCOL_API::pfnPacketFree.
+ This routine then releases the port resources allocated by ::EslSocketPortAllocate
+ and calls the network specific port close routine (e.g. ::EslTcp4PortClose)
+ via ESL_PROTOCOL_API::pfnPortClose to release any network specific resources.
+ </li>
+ </ul>
+
+
+ \section ReceiveEngine Receive Engine
+
+ The receive path accepts data from the network and queues (buffers) it for the
+ application. Flow control is applied once a maximum amount of buffering is reached
+ and is released when the buffer usage drops below that limit. Eventually the
+ application requests data from the socket which removes entries from the queue and
+ returns the data.
+
+ The receive engine is the state machine which reads data from the network and
+ fills the queue with received packets. The receive engine uses two data structures
+ to manage the network receive opeations and the buffers.
+
+ At a high level, the ::ESL_IO_MGMT structures are managing the tokens and
+ events for the interface to the UEFI network stack. The ::ESL_PACKET
+ structures are managing the receive data buffers. The receive engine
+ connects these two structures in the network specific receive completion
+ routines.
+
+<code><pre>
+
+ +------------------+
+ | ::ESL_PORT |
+ | |
+ +------------------+
+ | ::ESL_IO_MGMT |
+ +------------------+
+ | ESL_IO_MGMT |
+ +------------------+
+ . .
+ . ESL_IO_MGMT .
+ . .
+ +------------------+
+
+</pre></code>
+
+ The ::ESL_IO_MGMT structures are allocated as part of the ::ESL_PORT structure in
+ ::EslSocketPortAllocate. The ESL_IO_MGMT structures are separated and placed on
+ the free list by calling ::EslSocketIoInit. The ESL_IO_MGMT structure contains
+ the network layer specific receive completion token and event. The receive engine
+ is eventually shutdown by ::EslSocketPortCloseTxDone and the resources in these
+ structures are released in ::EslSocketPortClose by a call to ::EslSocketIoFree.
+
+<code><pre>
+
+ pPort->pRxActive
+ |
+ V
+ +-------------+ +-------------+ +-------------+
+ Active | ESL_IO_MGMT |-->| ESL_IO_MGMT |-->| ESL_IO_MGMT |--> NULL

+ +-------------+ +-------------+ +-------------+
+ ^
+ |
+ pPort->pRxFree
+</pre></code>
+
+ The receive engine is started by calling ::EslSocketRxStart. Flow control pauses
+ the receive engine by stopping the calls to EslSocketRxStart when the amount of
+ receive data waiting for the application meets or exceeds MAX_RX_DATA. After
+ the application reads enough data that the amount of buffering drops below this
+ limit, the calls to EslSockeRxStart continue which releases the flow control.
+
+ Receive flow control is applied when the port is created, since no receive
+ operation are pending to the low layer network driver. The flow control gets
+ released when the low layer network port is configured or the first receive
+ operation is posted. Flow control remains in the released state until the
+ maximum buffer space is consumed. During this time, ::EslSocketRxComplete
+ calls ::EslSocketRxStart. Flow control is applied in EslSocketRxComplete
+ by skipping the call to EslSocketRxStart. Flow control is eventually
+ released in ::EslSocketReceive when the buffer space drops below the
+ maximum amount causing EslSocketReceive to call EslSocketRxStart.
+
+<code><pre>
+
+ +------------+ +------------+
+ High .----->| ESL_PACKET |-->| ESL_PACKET |--> NULL (pNext)

+
+</pre></code>
+
+ ::EslSocketRxStart connects an ::ESL_PACKET structure to the ::ESL_IO_MGMT structure
+ and then calls the network layer to start the receive operation. Upon
+ receive completion, ::EslSocketRxComplete breaks the connection between these
+ structrues and places the ESL_IO_MGMT structure onto the ESL_PORT::pRxFree list to
+ make token and event available for another receive operation. EslSocketRxComplete
+ then queues the ESL_PACKET structure (data packet) to either the
+ ESL_SOCKET::pRxOobPacketListTail or ESL_SOCKET::pRxPacketListTail depending on
+ whether urgent or normal data was received. Finally ::EslSocketRxComplete attempts
+ to start another receive operation.

+
+</pre></code>
+
+ To minimize the number of buffer copies, the data is not copied until the
+ application makes a receive call. At this point socket performs a single copy
+ in the receive path to move the data from the buffer filled by the network layer
+ into the application's buffer.
+
+ The IP4 and UDP4 drivers go one step further to reduce buffer copies. They
+ allow the socket layer to hold on to the actual receive buffer until the
+ application has performed a receive operation or closes the socket. Both
+ of theses operations return the buffer to the lower layer network driver
+ by calling ESL_PROTOCOL_API::pfnPacketFree.
+
+ When a socket application wants to receive data it indirectly calls
+ ::EslSocketReceive to remove data from one of the receive data queues. This routine
+ removes the next available packet from ESL_SOCKET::pRxOobPacketListHead or
+ ESL_SOCKET::pRxPacketListHead and copies the data from the packet
+ into the application's buffer. For SOCK_STREAM sockets, if the packet
+ contains more data then the ESL_PACKET structures remains at the head of the
+ receive queue for the next application receive
+ operation. For SOCK_DGRAM, SOCK_RAW and SOCK_SEQ_PACKET sockets, the ::ESL_PACKET
+ structure is removed from the head of the receive queue and any remaining data is
+ discarded as the packet is placed on the free queue.
+
+ During socket layer shutdown, ::EslSocketShutdown calls ::EslSocketRxCancel to
+ cancel any pending receive operations. EslSocketRxCancel calls the network specific
+ cancel routine using ESL_PORT::pfnRxCancel.
+
+
+ \section TransmitEngine Transmit Engine
+
+ Application calls to ::EslSocketTransmit cause data to be copied into a buffer.
+ The buffer exists as an extension to an ESL_PACKET structure and the structure
+ is placed at the end of the transmit queue.
+
+<code><pre>
+
+ *ppQueueHead: pSocket->pRxPacketListHead or pSocket->pRxOobPacketListHead
+ |
+ V
+ +------------+ +------------+ +------------+
+ Data | ESL_PACKET |-->| ESL_PACKET |-->| ESL_PACKET |--> NULL
+ +------------+ +------------+ +------------+
+ ^
+ |
+ *ppQueueTail: pSocket->pRxPacketListTail or pSocket->pRxOobPacketListTail
+
+</pre></code>
+
+ There are actually two transmit queues the normal or low priority queue which is
+ the default and the urgent or high priority queue which is addressed by specifying
+ the MSG_OOB flag during the transmit request. Associated with each queue is a
+ transmit engine which is responsible for sending the data in that queue.
+
+ The transmit engine is the state machine which removes entries from the head
+ of the transmit queue and causes the data to be sent over the network.
+

+
+ At a high level, the transmit engine uses a couple of data structures
+ to manage the data flow. The ::ESL_IO_MGMT structures manage the tokens and
+ events for the interface to the UEFI network stack. The ::ESL_PACKET
+ structures manage the data buffers that get sent. The transmit
+ engine connects these two structures prior to transmission and disconnects
+ them upon completion.
+
+<code><pre>
+
+ pPort->pTxActive or pTxOobActive
+ |
+ V
+ +-------------+ +-------------+ +-------------+
+ Active | ESL_IO_MGMT |-->| ESL_IO_MGMT |-->| ESL_IO_MGMT |--> NULL
+ +-------------+ +-------------+ +-------------+
+
+ +-------------+ +-------------+ +-------------+
+ Free | ESL_IO_MGMT |-->| ESL_IO_MGMT |-->| ESL_IO_MGMT |--> NULL
+ +-------------+ +-------------+ +-------------+
+ ^
+ |
+ pPort->pTxFree or pTxOobFree
+
+</pre></code>
+
+ The transmit engine manages multiple transmit operations using the
+ active and free lists shown above. ::EslSocketPortAllocate allocates the
+ ::ESL_IO_MGMT structures as an extension to the ::ESL_PORT structure.
+ This routine places the ESL_IO_MGMT structures on the free list by calling
+ ::EslSocketIoInit. During their lifetime, the ESL_IO_MGMT structures
+ will move from the free list to the active list and back again. The
+ active list contains the packets that are actively being processed by
+ the UEFI network stack. Eventually the ESL_IO_MGMT structures will be
+ removed from the free list and be deallocated by the EslSocketPortClose
+ routine.
+
+ The network specific code calls the ::EslSocketTxStart routine
+ to hand a packet to the network stack. EslSocketTxStart connects
+ the transmit packet (::ESL_PACKET) to an ::ESL_IO_MGMT structure
+ and then queues the result to one of the active lists:
+ ESL_PORT::pTxActive or ESL_PORT::pTxOobActive. The routine then
+ hands the packet to the network stack.
+
+ Upon completion, the network specific TxComplete routine calls
+ ::EslSocketTxComplete to disconnect the transmit packet from the
+ ESL_IO_MGMT structure and frees the ::ESL_PACKET structure by calling
+ ::EslSocketPacketFree. The routine places the ::ESL_IO_MGMT structure
+ into the free list either ESL_PORT::pTxFree or ESL_PORT::pTxOobFree.
+ EslSocketTxComplete then starts the next transmit operation while
+ the socket is active or calls the ::EslSocketPortCloseTxDone routine
+ when the socket is shutting down.
