- *
- * * Support spaces in filenames
- *
- * 2010-04-29 Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
- *
- * * Added USER/PASS authentication.
- *
- * 2001-01-31 Sergei Organov <osv@javad.ru>
- *
- * * Hacks with current dir and root dir removed in favor of new libio
- * support for task-local current and root directories.
- *
- * 2001-01-30 Sergei Organov <osv@javad.ru>
- *
- * * Bug in `close_data_socket()' introduced by previous change fixed.
- * * `command_pasv()' changed to set timeout on socket we are listening on
- * and code fixed to don't close socket twice on error.
- * * `serr()' changed to clear `errno'.
- * * `data_socket()' changed to clear `errno' before `bind()'.
- * * `session()' changed to clear `errno' before processing session.
- *
- * 2001-01-29 Sergei Organov <osv@javad.ru>
- *
- * * `close_data_socket()' fixed to close both active and passive sockets
- * * Initialize info->data_socket to -1 in `daemon()'
- * * Initialize `fname' to empty string in `exec_command()'
- *
- * 2001-01-22 Sergei Organov <osv@javad.ru>
- *
- * * Timeouts on sockets implemented. 'idle' field added to
- * configuration. No timeout by default to keep backward compatibility.
- * Note: SITE IDLE command not implemented yet.
- * * Basic global access control implemented. 'access' field added to
- * configuration. No access limitations by default to keep backward
- * compatibility.
- *
- * 2001-01-17 Sergei Organov <osv@javad.ru>
- *
- * * Anchor data socket for active mode (using self IP and port 20.)
- * * Fixed default data port support (still not tested).
- * * Don't allow IP address different from originating host in
- * PORT command to improve security.
- * * Fixed bug in MDTM command.
- * * Check for correctness of parsing of argument in command_port().
- * * Fixed squeeze_path() to don't allow names like 'NAME/smth' where
- * 'NAME' is not a directory.
- * * Command parsing a little bit improved: command names are now
- * converted to upper-case to be more compatible with RFC (command
- * names are not case-sensitive.)
- * * Reformat comments so that they have RTEMS look-and-feel.
- *
- * 2001-01-16 Sergei Organov <osv@javad.ru>
- *
- * * Fixed DELE, SITE CHMOD, RMD, MKD broken by previous changes
- * * True ASCII mode implemented (doesn't work for hooks and /dev/null)
- * * Passive mode implemented, PASV command added.
- * * Default port for data connection could be used (untested, can't find
- * ftp client that doesn't send PORT command)
- * * SYST reply changed to UNIX, as former RTEMS isn't registered name.
- * * Reply codes reviewed and fixed.
- *
- * 2001-01-08 Sergei Organov <osv@javad.ru>
- *
- * * use pool of pre-created threads to handle sessions
- * * LIST output now similar to what "/bin/ls -al" would output, thus
- * FTP clients could parse it.
- * * LIST NAME now works (both for files and directories)
- * * keep track of CWD for every session separately
- * * ability to specify root directory name in configuration table
- * * options sent in commands are ignored, thus LIST -al FILE works
- * * added support for NLST, CDUP and MDTM commands
- * * buffers are allocated on stack instead of heap where possible
- * * drop using of task notepad to pass parameters - use function
- * arguments instead
- * * various bug-fixes, e.g., use of PF_INET in socket() instead of
- * AF_INET, use snprintf() instead of sprintf() everywhere for safety,
- * etc.

-/*************************************************************************
- * ftpd.c
- *************************************************************************
- * Description:
- *
- * This file contains the daemon which services requests that appear
- * on the FTP port. This server is compatible with FTP, but it
- * also provides 'hooks' to make it usable in situations where files
- * are not used/necessary. Once the server is started, it runs
- * forever.
- *
- *
- * Organization:
- *
- * The FTP daemon is started upon boot along with a (configurable)
- * number of tasks to handle sessions. It runs all the time and
- * waits for connections on the known FTP port (21). When
- * a connection is made, it wakes-up a 'session' task. That
- * session then interacts with the remote host. When the session
- * is complete, the session task goes to sleep. The daemon still
- * runs, however.
- *
- *
- * Supported commands are:
- *
- * RETR xxx - Sends a file from the client.
- * STOR xxx - Receives a file from the client. xxx = filename.
- * LIST xxx - Sends a file list to the client.
- * NLST xxx - Sends a file list to the client.
- * USER - Does nothing.
- * PASS - Does nothing.
- * SYST - Replies with the system type (`RTEMS').
- * DELE xxx - Delete file xxx.
- * MKD xxx - Create directory xxx.
- * RMD xxx - Remove directory xxx.
- * PWD - Print working directory.
- * CWD xxx - Change working directory.
- * CDUP - Change to upper directory.
- * SITE CHMOD xxx yyy - Change permissions on file yyy to xxx.
- * PORT a,b,c,d,x,y - Setup for a data port to IP address a.b.c.d
- * and port (x*256 + y).
- * MDTM xxx - Send file modification date/time to the client.
- * xxx = filename.
- * PASV - Use passive mode data connection.
- *
- *
- * The public routines contained in this file are:
- *
- * rtems_initialize_ftpd - Initializes and starts the server daemon,
- * then returns to its caller.

- * You can mount the FTP file system with a call to mount() or
- * mount_and_make_target_path() with the @ref RTEMS_FILESYSTEM_TYPE_FTPFS file
- * system type.
- *
- * You have to add @ref CONFIGURE_FILESYSTEM_FTPFS to your application
- * configuration.
- *
- * You can open files either read-only or write-only. A seek is not allowed.
- * A close terminates the control and data connections.
- *
- * To open a file @c file.txt in the directory @c dir (relative to home
- * directory of the server) on a server named @c host using the user name
- * @c user and the password @c pw you must specify the following path:
- * <tt>/FTP/user:pw@@host/dir/file.txt</tt>.
- *
- * If the server is the default server specified in BOOTP, it can be ommitted:
- * <tt>/FTP/user:pw/dir/file.txt</tt>.
- *
- * The user name will be used for the password if it is ommitted:
- * <tt>/FTP/user@@host/dir/file.txt</tt>.
- *
- * For the data transfer passive (= default) and active (= fallback) mode are
- * supported.
