71 | ::mEslLayer is the one and only ::ESL_LAYER structure. It connects directly or\r | |
72 | indirectly to the other data structures. The ESL_LAYER structure has a unique\r | |
73 | service list for each of the network protocol interfaces.\r | |
74 | \r | |
75 | ::ESL_SERVICE manages the network interfaces for a given transport type (IP4, TCP4, UDP4, etc.)\r | |
76 | \r | |
77 | ::ESL_SOCKET manages the activity for a single socket instance. As such, it contains\r | |
78 | the ::EFI_SOCKET_PROTOCOL structure which the BSD socket library uses as the object\r | |
79 | reference and the API into the EFI socket library.\r | |
80 | \r | |
81 | ::ESL_PORT manages the connection with a single instance of the lower layer network.\r | |
82 | This structure is the socket equivalent of an IP connection or a TCP or UDP port.\r | |
83 | \r | |
84 | ::ESL_PACKET buffers data for transmit and receive. There are four queues connected\r | |
85 | to the ::ESL_SOCKET that manage the data:\r | |
86 | <ul>\r | |
87 | <li>ESL_SOCKET::pRxPacketListHead - Normal (low) priority receive data</li>\r | |
88 | <li>ESL_SOCKET::pRxOobPacketListHead - High (out-of-band or urgent) priority receive data</li>\r | |
89 | <li>ESL_SOCKET::pTxPacketListHead - Normal (low) priority transmit data</li>\r | |
90 | <li>ESL_SOCKET::pTxOobPacketListHead - High (out-of-band or urgent) priority transmit data</li>\r | |
91 | </ul>\r | |
92 | The selection of the transmit queue is controlled by the MSG_OOB flag on the transmit\r | |
93 | request as well as the socket option SO_OOBINLINE. The receive queue is selected by\r | |
94 | the URGENT data flag for TCP and the setting of the socket option SO_OOBINLINE.\r | |
95 | \r | |
96 | Data structure synchronization is done by raising TPL to TPL_SOCKET. Modifying\r | |
97 | critical elements within the data structures must be done at this TPL. TPL is then\r | |
98 | restored to the previous level. Note that the code verifies that all callbacks are\r | |
99 | entering at TPL_SOCKETS for proper data structure synchronization.\r | |

101 | \section PortCloseStateMachine Port Close State Machine\r | |
102 | \r | |
103 | The port close state machine walks the port through the necessary\r | |
104 | states to stop activity on the port and get it into a state where\r | |
105 | the resources may be released. The state machine consists of the\r | |
106 | following arcs and states:\r | |
107 | \r | |

176 | \section ReceiveEngine Receive Engine\r | |
177 | \r | |
178 | The receive path accepts data from the network and queues (buffers) it for the\r | |
179 | application. Flow control is applied once a maximum amount of buffering is reached\r | |
180 | and is released when the buffer usage drops below that limit. Eventually the\r | |
181 | application requests data from the socket which removes entries from the queue and\r | |
182 | returns the data.\r | |
183 | \r | |
184 | The receive engine is the state machine which reads data from the network and\r | |
185 | fills the queue with received packets. The receive engine uses two data structures\r | |
186 | to manage the network receive opeations and the buffers.\r | |
187 | \r | |
188 | At a high level, the ::ESL_IO_MGMT structures are managing the tokens and\r | |
189 | events for the interface to the UEFI network stack. The ::ESL_PACKET\r | |
190 | structures are managing the receive data buffers. The receive engine\r | |
191 | connects these two structures in the network specific receive completion\r | |
192 | routines.\r | |
193 | \r | |
194 | <code><pre>\r | |

211 | The ::ESL_IO_MGMT structures are allocated as part of the ::ESL_PORT structure in\r | |
212 | ::EslSocketPortAllocate. The ESL_IO_MGMT structures are separated and placed on\r | |
213 | the free list by calling ::EslSocketIoInit. The ESL_IO_MGMT structure contains\r | |
214 | the network layer specific receive completion token and event. The receive engine\r | |
215 | is eventually shutdown by ::EslSocketPortCloseTxDone and the resources in these\r | |
216 | structures are released in ::EslSocketPortClose by a call to ::EslSocketIoFree.\r | |
217 | \r | |
218 | <code><pre>\r | |

233 | </pre></code>\r | |
234 | \r | |
235 | The receive engine is started by calling ::EslSocketRxStart. Flow control pauses\r | |
236 | the receive engine by stopping the calls to EslSocketRxStart when the amount of\r | |
237 | receive data waiting for the application meets or exceeds MAX_RX_DATA. After\r | |
238 | the application reads enough data that the amount of buffering drops below this\r | |
239 | limit, the calls to EslSockeRxStart continue which releases the flow control.\r | |
240 | \r | |
241 | Receive flow control is applied when the port is created, since no receive\r | |
242 | operation are pending to the low layer network driver. The flow control gets\r | |
243 | released when the low layer network port is configured or the first receive\r | |
244 | operation is posted. Flow control remains in the released state until the\r | |
245 | maximum buffer space is consumed. During this time, ::EslSocketRxComplete\r | |
246 | calls ::EslSocketRxStart. Flow control is applied in EslSocketRxComplete\r | |
247 | by skipping the call to EslSocketRxStart. Flow control is eventually\r | |
248 | released in ::EslSocketReceive when the buffer space drops below the\r | |
249 | maximum amount causing EslSocketReceive to call EslSocketRxStart.\r | |

269 | ::EslSocketRxStart connects an ::ESL_PACKET structure to the ::ESL_IO_MGMT structure\r | |
270 | and then calls the network layer to start the receive operation. Upon \r | |
271 | receive completion, ::EslSocketRxComplete breaks the connection between these\r | |
272 | structrues and places the ESL_IO_MGMT structure onto the ESL_PORT::pRxFree list to\r | |
273 | make token and event available for another receive operation. EslSocketRxComplete\r | |
274 | then queues the ESL_PACKET structure (data packet) to either the\r | |
275 | ESL_SOCKET::pRxOobPacketListTail or ESL_SOCKET::pRxPacketListTail depending on\r | |
276 | whether urgent or normal data was received. Finally ::EslSocketRxComplete attempts\r | |
277 | to start another receive operation.\r | |

335 | \r | |
336 | To minimize the number of buffer copies, the data is not copied until the\r | |
337 | application makes a receive call. At this point socket performs a single copy\r | |
338 | in the receive path to move the data from the buffer filled by the network layer\r | |
339 | into the application's buffer.\r | |
340 | \r | |
341 | The IP4 and UDP4 drivers go one step further to reduce buffer copies. They\r | |
342 | allow the socket layer to hold on to the actual receive buffer until the\r | |
343 | application has performed a receive operation or closes the socket. Both\r | |
344 | of theses operations return the buffer to the lower layer network driver\r | |
345 | by calling ESL_PROTOCOL_API::pfnPacketFree.\r | |
346 | \r | |
347 | When a socket application wants to receive data it indirectly calls\r | |
348 | ::EslSocketReceive to remove data from one of the receive data queues. This routine\r | |
349 | removes the next available packet from ESL_SOCKET::pRxOobPacketListHead or\r | |
350 | ESL_SOCKET::pRxPacketListHead and copies the data from the packet\r | |
351 | into the application's buffer. For SOCK_STREAM sockets, if the packet\r | |
352 | contains more data then the ESL_PACKET structures remains at the head of the\r | |
353 | receive queue for the next application receive\r | |
354 | operation. For SOCK_DGRAM, SOCK_RAW and SOCK_SEQ_PACKET sockets, the ::ESL_PACKET\r | |
355 | structure is removed from the head of the receive queue and any remaining data is\r | |
356 | discarded as the packet is placed on the free queue.\r | |
357 | \r | |
358 | During socket layer shutdown, ::EslSocketShutdown calls ::EslSocketRxCancel to\r | |
359 | cancel any pending receive operations. EslSocketRxCancel calls the network specific\r | |
360 | cancel routine using ESL_PORT::pfnRxCancel.\r | |

363 | \section TransmitEngine Transmit Engine\r | |

365 | Application calls to ::EslSocketTransmit cause data to be copied into a buffer.\r | |

384 | the default and the urgent or high priority queue which is addressed by specifying\r | |
385 | the MSG_OOB flag during the transmit request. Associated with each queue is a\r | |
386 | transmit engine which is responsible for sending the data in that queue.\r | |
387 | \r | |
388 | The transmit engine is the state machine which removes entries from the head\r | |

405 | At a high level, the transmit engine uses a couple of data structures\r | |
406 | to manage the data flow. The ::ESL_IO_MGMT structures manage the tokens and\r | |
407 | events for the interface to the UEFI network stack. The ::ESL_PACKET\r | |
408 | structures manage the data buffers that get sent. The transmit\r | |
409 | engine connects these two structures prior to transmission and disconnects\r | |
410 | them upon completion.\r | |

435 | will move from the free list to the active list and back again. The\r | |
436 | active list contains the packets that are actively being processed by\r | |
437 | the UEFI network stack. Eventually the ESL_IO_MGMT structures will be\r | |
438 | removed from the free list and be deallocated by the EslSocketPortClose\r | |
439 | routine.\r | |
440 | \r | |
441 | The network specific code calls the ::EslSocketTxStart routine\r | |
442 | to hand a packet to the network stack. EslSocketTxStart connects\r | |
443 | the transmit packet (::ESL_PACKET) to an ::ESL_IO_MGMT structure\r | |
444 | and then queues the result to one of the active lists:\r | |
445 | ESL_PORT::pTxActive or ESL_PORT::pTxOobActive. The routine then\r | |
446 | hands the packet to the network stack.\r | |
447 | \r | |
448 | Upon completion, the network specific TxComplete routine calls\r | |
449 | ::EslSocketTxComplete to disconnect the transmit packet from the\r | |
450 | ESL_IO_MGMT structure and frees the ::ESL_PACKET structure by calling\r | |
451 | ::EslSocketPacketFree. The routine places the ::ESL_IO_MGMT structure\r | |
452 | into the free list either ESL_PORT::pTxFree or ESL_PORT::pTxOobFree.\r | |
453 | EslSocketTxComplete then starts the next transmit operation while\r | |
454 | the socket is active or calls the ::EslSocketPortCloseTxDone routine\r | |
455 | when the socket is shutting down.\r | |
