29 * smb_com_search
30 * smb_com_find, smb_com_find_close
31 * smb_find_unique
32 *
33 * These commands are used for directory searching. 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.
