f737cfb9 | 1071 | Used to perform TFTP and MTFTP services.\r |
1072 | \r | |
1073 | This function is used to perform TFTP and MTFTP services. This includes the\r | |
1074 | TFTP operations to get the size of a file, read a directory, read a file, and\r | |
1075 | write a file. It also includes the MTFTP operations to get the size of a file,\r | |
1076 | read a directory, and read a file. The type of operation is specified by Operation.\r | |
1077 | If the callback function that is invoked during the TFTP/MTFTP operation does\r | |
1078 | not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will\r | |
1079 | be returned.\r | |
1080 | For read operations, the return data will be placed in the buffer specified by\r | |
1081 | BufferPtr. If BufferSize is too small to contain the entire downloaded file,\r | |
1082 | then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero\r | |
1083 | or the size of the requested file (the size of the requested file is only returned\r | |
1084 | if the TFTP server supports TFTP options). If BufferSize is large enough for the\r | |
1085 | read operation, then BufferSize will be set to the size of the downloaded file,\r | |
1086 | and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services\r | |
1087 | should use the get-file-size operations to determine the size of the downloaded\r | |
1088 | file prior to using the read-file operations-especially when downloading large\r | |
1089 | (greater than 64 MB) files-instead of making two calls to the read-file operation.\r | |
1090 | Following this recommendation will save time if the file is larger than expected\r | |
1091 | and the TFTP server does not support TFTP option extensions. Without TFTP option\r | |
1092 | extension support, the client has to download the entire file, counting and discarding\r | |
1093 | the received packets, to determine the file size.\r | |
1094 | For write operations, the data to be sent is in the buffer specified by BufferPtr.\r | |
1095 | BufferSize specifies the number of bytes to send. If the write operation completes\r | |
1096 | successfully, then EFI_SUCCESS will be returned.\r | |
1097 | For TFTP "get file size" operations, the size of the requested file or directory\r | |
1098 | is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server\r | |
1099 | does not support options, the file will be downloaded into a bit bucket and the\r | |
1100 | length of the downloaded file will be returned. For MTFTP "get file size" operations,\r | |
1101 | if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED\r | |
1102 | will be returned.\r | |
1103 | This function can take up to 10 seconds to timeout and return control to the caller.\r | |
1104 | If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.\r | |
1105 | If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,\r | |
1106 | then the TFTP sequence is stopped and EFI_ABORTED will be returned.\r | |
1107 | The format of the data returned from a TFTP read directory operation is a null-terminated\r | |
1108 | filename followed by a null-terminated information string, of the form\r | |
1109 | "size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f - note that\r | |
1110 | the seconds field can be a decimal number), where the date and time are UTC. For\r | |
1111 | an MTFTP read directory command, there is additionally a null-terminated multicast\r | |
1112 | IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The final\r | |
1113 | entry is itself null-terminated, so that the final information string is terminated\r | |
1114 | with two null octets.\r | |

e2851998 | 1880 | \r |
f737cfb9 | 1881 | The NewFilter field is used to modify the network device's current IP receive\r |
1882 | filter settings and to enable a software filter. This function updates the IpFilter\r | |
1883 | field of the EFI_PXE_BASE_CODE_MODE structure with the contents of NewIpFilter.\r | |
1884 | The software filter is used when the USE_FILTER in OpFlags is set to UdpRead().\r | |
1885 | The current hardware filter remains in effect no matter what the settings of OpFlags\r | |
1886 | are, so that the meaning of ANY_DEST_IP set in OpFlags to UdpRead() is from those\r | |
1887 | packets whose reception is enabled in hardware-physical NIC address (unicast),\r | |
1888 | broadcast address, logical address or addresses (multicast), or all (promiscuous).\r | |
1889 | UdpRead() does not modify the IP filter settings.\r | |
1890 | Dhcp(), Discover(), and Mtftp() set the IP filter, and return with the IP receive\r | |
1891 | filter list emptied and the filter set to EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP.\r | |
1892 | If an application or driver wishes to preserve the IP receive filter settings,\r | |
1893 | it will have to preserve the IP receive filter settings before these calls, and\r | |
1894 | use SetIpFilter() to restore them after the calls. If incompatible filtering is\r | |
1895 | requested (for example, PROMISCUOUS with anything else) or if the device does not\r | |
1896 | support a requested filter setting and it cannot be accommodated in software\r | |
1897 | (for example, PROMISCUOUS not supported), EFI_INVALID_PARAMETER will be returned.\r | |
1898 | The IPlist field is used to enable IPs other than the StationIP. They may be\r | |
1899 | multicast or unicast. If IPcnt is set as well as EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP,\r | |
1900 | then both the StationIP and the IPs from the IPlist will be used.\r | |
