They share the same 33 * message formats, defined below: 34 * 35 * Client Request Description 36 * ---------------------------------- --------------------------------- 37 * 38 * UCHAR WordCount; Count of parameter words = 2 39 * USHORT MaxCount; Number of dir. entries to return 40 * USHORT SearchAttributes; 41 * USHORT ByteCount; Count of data bytes; min = 5 42 * UCHAR BufferFormat1; 0x04 -- ASCII 43 * UCHAR FileName[]; File name, may be null 44 * UCHAR BufferFormat2; 0x05 -- Variable block 45 * USHORT ResumeKeyLength; Length of resume key, may be 0 46 * UCHAR ResumeKey[]; Resume key 47 * 48 * FileName specifies the file to be sought. SearchAttributes indicates 49 * the attributes that the file must have. If SearchAttributes is 50 * zero then only normal files are returned. If the system file, hidden or 51 * directory attributes are specified then the search is inclusive - both the 52 * specified type(s) of files and normal files are returned. If the volume 53 * label attribute is specified then the search is exclusive, and only the 54 * volume label entry is returned. 55 * 56 * MaxCount specifies the number of directory entries to be returned. 57 * 58 * Server Response Description 59 * ---------------------------------- --------------------------------- 60 * 61 * UCHAR WordCount; Count of parameter words = 1 62 * USHORT Count; Number of entries returned 63 * USHORT ByteCount; Count of data bytes; min = 3 64 * UCHAR BufferFormat; 0x05 -- Variable block 65 * USHORT DataLength; Length of data 66 * UCHAR DirectoryInformationData[]; Data 67 * 68 * The response will contain one or more directory entries as determined by 69 * the Count field. No more than MaxCount entries will be returned. Only 70 * entries that match the sought FileName and SearchAttributes combination 71 * will be returned. 72 * 73 * ResumeKey must be null (length = 0) on the initial search request. 74 * Subsequent search requests intended to continue a search must contain 75 * the ResumeKey field extracted from the last directory entry of the 76 * previous response. ResumeKey is self-contained, for calls containing 77 * a non-zero ResumeKey neither the SearchAttributes or FileName fields 78 * will be valid in the request. ResumeKey has the following format: 79 * 80 * Resume Key Field Description 81 * ---------------------------------- --------------------------------- 82 * 83 * UCHAR Reserved; bit 7 - consumer use 84 * bits 5,6 - system use (must preserve) 85 * bits 0-4 - server use (must preserve) 86 * UCHAR FileName[11]; Name of the returned file 87 * UCHAR ReservedForServer[5]; Client must not modify 88 * byte 0 - uniquely identifies find 89 * through find_close 90 * bytes 1-4 - available for server use 91 * (must be non-zero) 92 * UCHAR ReservedForConsumer[4]; Server must not modify 93 * 94 * FileName is 8.3 format, with the three character extension left 95 * justified into FileName[9-11]. 96 * 97 * There may be multiple matching entries in response to a single request 98 * as wildcards are supported in the last component of FileName of the 99 * initial request. 100 * 101 * Returned directory entries in the DirectoryInformationData field of the 102 * response each have the following format: 103 * 104 * Directory Information Field Description 105 * ---------------------------------- --------------------------------- 106 * 107 * SMB_RESUME_KEY ResumeKey; Described above 108 * UCHAR FileAttributes; Attributes of the found file 109 * SMB_TIME LastWriteTime; Time file was last written 110 * SMB_DATE LastWriteDate; Date file was last written 111 * ULONG FileSize; Size of the file 112 * UCHAR FileName[13]; ASCII, space-filled null terminated 113 * 114 * FileName must conform to 8.3 rules, and is padded after the extension 115 * with 0x20 characters if necessary. 116 * 117 * As can be seen from the above structure, these commands cannot return 118 * long filenames, and cannot return UNICODE filenames. 119 * 120 * Files which have a size greater than 2^32 bytes should have the least 121 * significant 32 bits of their size returned in FileSize. 122 * 123 * smb_com_search 124 * -------------- 125 * 126 * If the client is prior to the LANMAN1.0 dialect, the returned FileName 127 * should be uppercased. 128 * If the client has negotiated a dialect prior to the LANMAN1.0 dialect, 129 * or if bit0 of the Flags2 SMB header field of the request is clear, 130 * the returned FileName should be uppercased. 131 * 132 * SMB_COM_SEARCH terminates when either the requested maximum number of 133 * entries that match the named file are found, or the end of directory is 134 * reached without the maximum number of matches being found. A response 135 * containing no entries indicates that no matching entries were found 136 * between the starting point of the search and the end of directory. 137 * 138 * 139 * The find, find_close and find_unique protocols may be used in place of 140 * the core "search" protocol when LANMAN 1.0 dialect has been negotiated. 141 * 142 * smb_com_find 143 * ------------ 144 * 145 * The find protocol is used to match the find OS/2 system call. 146 * 147 * The format of the find protocol is the same as the core "search" protocol. 148 * The difference is that the directory is logically Opened with a find protocol 149 * and logically closed with the find close protocol. 150 * As is true of a failing open, if a find request (find "first" request where 151 * resume_key is null) fails (no entries are found), no find close protocol is 152 * expected. 153 * 154 * If no global characters are present, a "find unique" protocol should be used 155 * (only one entry is expected and find close need not be sent). 156 * 157 * A find request will terminate when either the requested maximum number of 158 * entries that match the named file are found, or the end of directory is 159 * reached without the maximum number of matches being found. A response 160 * containing no entries indicates that no matching entries were found between 161 * the starting point of the search and the end of directory. 162 * 163 * If a find requests more data than can be placed in a message of the 164 * max-xmit-size for the TID specified, the server will return only the number 165 * of entries which will fit. 166 * 167 * 168 * smb_com_find_close 169 * ------------------ 170 * 171 * The find close protocol is used to match the find close OS/2 system call. 172 * 173 * Whereas the first find protocol logically opens the directory, subsequent 174 * find protocols presenting a resume_key further "read" the directory, the 175 * find close protocol "closes" the directory allowing the server to free any 176 * resources held in support of the directory search. 177 * 178 * In our implementation this translates to closing the odir. 179 * 180 * 181 * smb_com_find_unique 182 * ------------------- 183 * 184 * The format of the find unique protocol is the same as the core "search" 185 * protocol. The difference is that the directory is logically opened, any 186 * matching entries returned, and then the directory is logically closed. 187 * 188 * The resume search key key will be returned as in the find protocol and 189 * search protocol however it may NOT be returned to continue the search. 190 * Only one buffer of entries is expected and find close need not be sent. 191 * 192 * If a find unique requests more data than can be placed in a message of the 193 * max-xmit-size for the TID specified, the server will abort the virtual 194 * circuit to the consumer. 195 */ 196 197 #include <smbsrv/smb_incl.h> 198 199 /* *** smb_com_search *** */ 200 201 smb_sdrc_t 202 smb_pre_search(smb_request_t *sr) 203 { 204 DTRACE_SMB_1(op__Search__start, smb_request_t *, sr);
