The More Bit must be set in 55 * all packets but the last. 56 * 57 * Implementation number: The number of the implementation this request code 58 * is defined by. An implementation number of zero is used 59 * for requst codes/data formats which all implementations 60 * agree on. Implementation number 255 is reserved (for 61 * extensions, in case we run out). 62 * 63 * Request code: An implementation-specific code which specifies the 64 * operation to be (which has been) performed and/or the 65 * format and semantics of the data included in the packet. 66 * 67 * Err: Must be 0 for a request. For a response, holds an error 68 * code relating to the request. If nonzero, the operation 69 * requested wasn't performed. 70 * 71 * 0 - no error 72 * 1 - incompatible implementation number 73 * 2 - unimplemented request code 74 * 3 - format error (wrong data items, data size, packet size etc.) 75 * 4 - no data available (e.g. request for details on unknown peer) 76 * 5-6 I don't know 77 * 7 - authentication failure (i.e. permission denied) 78 * 79 * Number of data items: number of data items in packet. 0 to 500 80 * 81 * MBZ: A reserved data field, must be zero in requests and responses. 82 * 83 * Size of data item: size of each data item in packet. 0 to 500 84 * 85 * Data: Variable sized area containing request/response data. For 86 * requests and responses the size in octets must be greater 87 * than or equal to the product of the number of data items 88 * and the size of a data item. For requests the data area 89 * must be exactly 40 octets in length. For responses the 90 * data area may be any length between 0 and 500 octets 91 * inclusive. 92 * 93 * Message Authentication Code: Same as NTP spec, in definition and function. 94 * May optionally be included in requests which require 95 * authentication, is never included in responses. 96 * 97 * The version number, mode and keyid have the same function and are 98 * in the same location as a standard NTP packet. The request packet 99 * is the same size as a standard NTP packet to ease receive buffer 100 * management, and to allow the same encryption procedure to be used 101 * both on mode 7 and standard NTP packets. The mac is included when 102 * it is required that a request be authenticated, the keyid should be 103 * zero in requests in which the mac is not included. 104 * 105 * The data format depends on the implementation number/request code pair 106 * and whether the packet is a request or a response. The only requirement 107 * is that data items start in the octet immediately following the size 108 * word and that data items be concatenated without padding between (i.e. 109 * if the data area is larger than data_items*size, all padding is at 110 * the end). Padding is ignored, other than for encryption purposes. 111 * Implementations using encryption might want to include a time stamp 112 * or other data in the request packet padding. The key used for requests 113 * is implementation defined, but key 15 is suggested as a default. 114 */ 115 116/* 117 * union of raw addresses to save space 118 */ 119union addrun { 120 struct in6_addr addr6; 121 struct in_addr addr; 122}; 123 124#define MODE7_PAYLOAD_LIM 176 125 126typedef union req_data_u_tag { 127 u_int32 u32[MODE7_PAYLOAD_LIM / sizeof(u_int32)]; 128 char data[MODE7_PAYLOAD_LIM]; /* data area (176 byte max) */ 129} req_data_u; /* struct conf_peer must fit */ 130 131/* 132 * A request packet.
