They share the same 34 * message formats, defined below: 35 * 36 * Client Request Description 37 * ---------------------------------- --------------------------------- 38 * 39 * UCHAR WordCount; Count of parameter words = 2 40 * USHORT MaxCount; Number of dir. entries to return 41 * USHORT SearchAttributes; 42 * USHORT ByteCount; Count of data bytes; min = 5 43 * UCHAR BufferFormat1; 0x04 -- ASCII 44 * UCHAR FileName[]; File name, may be null 45 * UCHAR BufferFormat2; 0x05 -- Variable block 46 * USHORT ResumeKeyLength; Length of resume key, may be 0 47 * UCHAR ResumeKey[]; Resume key 48 * 49 * FileName specifies the file to be sought. SearchAttributes indicates 50 * the attributes that the file must have. If SearchAttributes is 51 * zero then only normal files are returned. If the system file, hidden or 52 * directory attributes are specified then the search is inclusive - both the 53 * specified type(s) of files and normal files are returned. If the volume 54 * label attribute is specified then the search is exclusive, and only the 55 * volume label entry is returned. 56 * 57 * MaxCount specifies the number of directory entries to be returned. 58 * 59 * Server Response Description 60 * ---------------------------------- --------------------------------- 61 * 62 * UCHAR WordCount; Count of parameter words = 1 63 * USHORT Count; Number of entries returned 64 * USHORT ByteCount; Count of data bytes; min = 3 65 * UCHAR BufferFormat; 0x05 -- Variable block 66 * USHORT DataLength; Length of data 67 * UCHAR DirectoryInformationData[]; Data 68 * 69 * The response will contain one or more directory entries as determined by 70 * the Count field. No more than MaxCount entries will be returned. Only 71 * entries that match the sought FileName and SearchAttributes combination 72 * will be returned. 73 * 74 * ResumeKey must be null (length = 0) on the initial search request. 75 * Subsequent search requests intended to continue a search must contain 76 * the ResumeKey field extracted from the last directory entry of the 77 * previous response. ResumeKey is self-contained, for calls containing 78 * a non-zero ResumeKey neither the SearchAttributes or FileName fields 79 * will be valid in the request. ResumeKey has the following format: 80 * 81 * Resume Key Field Description 82 * ---------------------------------- --------------------------------- 83 * 84 * UCHAR Reserved; bit 7 - consumer use 85 * bits 5,6 - system use (must preserve) 86 * bits 0-4 - server use (must preserve) 87 * UCHAR FileName[11]; Name of the returned file 88 * UCHAR ReservedForServer[5]; Client must not modify 89 * byte 0 - uniquely identifies find 90 * through find_close 91 * bytes 1-4 - available for server use 92 * (must be non-zero) 93 * UCHAR ReservedForConsumer[4]; Server must not modify 94 * 95 * FileName is 8.3 format, with the three character extension left 96 * justified into FileName[9-11]. 97 * 98 * There may be multiple matching entries in response to a single request 99 * as wildcards are supported in the last component of FileName of the 100 * initial request. 101 * 102 * Returned directory entries in the DirectoryInformationData field of the 103 * response each have the following format: 104 * 105 * Directory Information Field Description 106 * ---------------------------------- --------------------------------- 107 * 108 * SMB_RESUME_KEY ResumeKey; Described above 109 * UCHAR FileAttributes; Attributes of the found file 110 * SMB_TIME LastWriteTime; Time file was last written 111 * SMB_DATE LastWriteDate; Date file was last written 112 * ULONG FileSize; Size of the file 113 * UCHAR FileName[13]; ASCII, space-filled null terminated 114 * 115 * FileName must conform to 8.3 rules, and is padded after the extension 116 * with 0x20 characters if necessary. 117 * 118 * As can be seen from the above structure, these commands cannot return 119 * long filenames, and cannot return UNICODE filenames. 120 * 121 * Files which have a size greater than 2^32 bytes should have the least 122 * significant 32 bits of their size returned in FileSize. 123 * 124 * smb_com_search 125 * -------------- 126 * 127 * If the client is prior to the LANMAN1.0 dialect, the returned FileName 128 * should be uppercased. 129 * If the client has negotiated a dialect prior to the LANMAN1.0 dialect, 130 * or if bit0 of the Flags2 SMB header field of the request is clear, 131 * the returned FileName should be uppercased. 132 * 133 * SMB_COM_SEARCH terminates when either the requested maximum number of 134 * entries that match the named file are found, or the end of directory is 135 * reached without the maximum number of matches being found. A response 136 * containing no entries indicates that no matching entries were found 137 * between the starting point of the search and the end of directory. 138 * 139 * 140 * The find, find_close and find_unique protocols may be used in place of 141 * the core "search" protocol when LANMAN 1.0 dialect has been negotiated. 142 * 143 * smb_com_find 144 * ------------ 145 * 146 * The find protocol is used to match the find OS/2 system call. 147 * 148 * The format of the find protocol is the same as the core "search" protocol. 149 * The difference is that the directory is logically Opened with a find protocol 150 * and logically closed with the find close protocol. 151 * As is true of a failing open, if a find request (find "first" request where 152 * resume_key is null) fails (no entries are found), no find close protocol is 153 * expected. 154 * 155 * If no global characters are present, a "find unique" protocol should be used 156 * (only one entry is expected and find close need not be sent). 157 * 158 * A find request will terminate when either the requested maximum number of 159 * entries that match the named file are found, or the end of directory is 160 * reached without the maximum number of matches being found. A response 161 * containing no entries indicates that no matching entries were found between 162 * the starting point of the search and the end of directory. 163 * 164 * If a find requests more data than can be placed in a message of the 165 * max-xmit-size for the TID specified, the server will return only the number 166 * of entries which will fit. 167 * 168 * 169 * smb_com_find_close 170 * ------------------ 171 * 172 * The find close protocol is used to match the find close OS/2 system call. 173 * 174 * Whereas the first find protocol logically opens the directory, subsequent 175 * find protocols presenting a resume_key further "read" the directory, the 176 * find close protocol "closes" the directory allowing the server to free any 177 * resources held in support of the directory search. 178 * 179 * In our implementation this translates to closing the odir. 180 * 181 * 182 * smb_com_find_unique 183 * ------------------- 184 * 185 * The format of the find unique protocol is the same as the core "search" 186 * protocol. The difference is that the directory is logically opened, any 187 * matching entries returned, and then the directory is logically closed. 188 * 189 * The resume search key key will be returned as in the find protocol and 190 * search protocol however it may NOT be returned to continue the search. 191 * Only one buffer of entries is expected and find close need not be sent. 192 * 193 * If a find unique requests more data than can be placed in a message of the 194 * max-xmit-size for the TID specified, the server will abort the virtual 195 * circuit to the consumer. 196 */ 197 198 /* *** smb_com_search *** */ 199 200 smb_sdrc_t 201 smb_pre_search(smb_request_t *sr) 202 { 203 DTRACE_SMB_1(op__Search__start, smb_request_t *, sr);
