32  * These commands are used for directory searching. 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.
