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.
