127da6c28aaSamw * Comments
128da6c28aaSamw * --------
129da6c28aaSamw * The state machine of the odir structures is controlled by 3 elements:
130da6c28aaSamw * - The list of odirs of the tree it belongs to.
131da6c28aaSamw * - The mutex embedded in the structure itself.
132da6c28aaSamw * - The reference count.
133da6c28aaSamw *
134da6c28aaSamw * There's a mutex embedded in the odir structure used to protect its fields
135da6c28aaSamw * and there's a lock embedded in the list of odirs of a tree. To
136da6c28aaSamw * increment or to decrement the reference count the mutex must be entered.
137da6c28aaSamw * To insert the odir into the list of odirs of the tree and to remove
138da6c28aaSamw * the odir from it, the lock must be entered in RW_WRITER mode.
139da6c28aaSamw *
1407f667e74Sjose borrego * In order to avoid deadlocks, when both (mutex and lock of the odir
1417f667e74Sjose borrego * list) have to be entered, the lock must be entered first.

1867f667e74Sjose borrego * Odir Internals
1877f667e74Sjose borrego * --------------
1887f667e74Sjose borrego * The odir object represent an open directory search. Each read operation
1897f667e74Sjose borrego * provides the caller with a structure containing information pertaining
1907f667e74Sjose borrego * to the next directory entry that matches the search criteria, namely
1917f667e74Sjose borrego * the filename or match pattern and, in the case of smb_odir_read_fileinfo(),
1927f667e74Sjose borrego * the search attributes.
193da6c28aaSamw *
1947f667e74Sjose borrego * The odir maintains a buffer (d_buf) of directory entries read from
1957f667e74Sjose borrego * the filesystem via a vop_readdir. The buffer is populated when a read
1967f667e74Sjose borrego * request (smb_odir_next_odirent) finds that the buffer is empty or that
1977f667e74Sjose borrego * the end of the buffer has been reached, and also when a new client request
1987f667e74Sjose borrego * (find next) begins.
1997f667e74Sjose borrego *
2007f667e74Sjose borrego * The data in d_buf (that which is returned from the file system) can
2017f667e74Sjose borrego * be in one of two formats. If the file system supports extended directory
2027f667e74Sjose borrego * entries we request that the data be returned as edirent_t structures. If
2037f667e74Sjose borrego * it does not the data will be returned as dirent64_t structures. For
2047f667e74Sjose borrego * convenience, when the next directory entry is read from d_buf by
2057f667e74Sjose borrego * smb_odir_next_odirent it is translated into an smb_odirent_t.
2067f667e74Sjose borrego *
2077f667e74Sjose borrego * smb_odir_read_fileinfo
2087f667e74Sjose borrego * The processing required to obtain the information to populate the caller's
2097f667e74Sjose borrego * smb_fileinfo_t differs depending upon whether the directory search is for a
2107f667e74Sjose borrego * single specified filename or for multiple files matching a search pattern.
2117f667e74Sjose borrego * Thus smb_odir_read_fileinfo uses two static functions:
2127f667e74Sjose borrego * smb_odir_single_fileinfo - obtains the smb_fileinfo_t info for the single
2137f667e74Sjose borrego * filename as specified in smb_odir_open request.
2147f667e74Sjose borrego * smb_odir_wildcard_fileinfo - obtains the smb_fileinfo_t info for the filename
2157f667e74Sjose borrego * returned from the smb_odir_next_odirent. This is called in a loop until
2167f667e74Sjose borrego * an entry matching the search criteria is found or no more entries exist.
2177f667e74Sjose borrego *
2187f667e74Sjose borrego * If a directory entry is a VLNK, the name returned in the smb_fileinfo_t
2197f667e74Sjose borrego * is the name of the directory entry but the attributes are the attribites
2207f667e74Sjose borrego * of the file that is the target of the link. If the link target cannot
2217f667e74Sjose borrego * be found the attributes returned are the attributes of the link itself.
2227f667e74Sjose borrego *
223037cac00Sjoyce mcintosh * smb_odir_read_streaminfo
2247f667e74Sjose borrego * In order for an odir to provide information about stream files it
2257f667e74Sjose borrego * must be opened with smb_odir_openat(). smb_odir_read_streaminfo() can
2267f667e74Sjose borrego * then be used to obtain the name and size of named stream files.
2277f667e74Sjose borrego *
2287f667e74Sjose borrego * Resuming a Search
2297f667e74Sjose borrego * -----------------
2307f667e74Sjose borrego * A directory search often consists of multiple client requests: an initial
2317f667e74Sjose borrego * find_first request followed by zero or more find_next requests and a
2327f667e74Sjose borrego * find_close request.
2337f667e74Sjose borrego * The find_first request will open and lookup the odir, read its desired
2347f667e74Sjose borrego * number of entries from the odir, then release the odir and return.
2357f667e74Sjose borrego * A find_next request will lookup the odir and read its desired number of
2367f667e74Sjose borrego * entries from the odir, then release the odir and return.
2377f667e74Sjose borrego * At the end of the search the find_close request will close the odir.
2387f667e74Sjose borrego *
2397f667e74Sjose borrego * In order to be able to resume a directory search (find_next) the odir
2407f667e74Sjose borrego * provides the capability for the caller to save one or more resume points
2417f667e74Sjose borrego * (cookies) at the end of a request, and to specify which resume point
2427f667e74Sjose borrego * (cookie) to restart from at the beginning of the next search.
2437f667e74Sjose borrego * smb_odir_save_cookie(..., cookie)
2447f667e74Sjose borrego * smb_odir_resume_at(smb_odir_resume_t *resume)
2457f667e74Sjose borrego * A search can be resumed at a specified resume point (cookie), the resume
2467f667e74Sjose borrego * point (cookie) stored at a specified index in the d_cookies array, or
2477f667e74Sjose borrego * a specified filename. The latter (specified filename) is not yet supported.
2487f667e74Sjose borrego *
2497f667e74Sjose borrego * See smb_search, smb_find, smb_find_unique, and smb_trans2_find for details
