+/* FIXME: 1. Parse command is a hack. We can do better.
+ * 2. OSV: hooks support seems to be bad, as it requires storing of
+ * entire input file in memory. Seem to be better to change it to
+ * something more reasonable, like having
+ * 'hook_write(void const *buf, int count)' routine that will be
+ * called multiple times while file is being received.
+ * 3. OSV: Remove hack with "/dev/null"?
+ *
+ * FTP Server Daemon
+ *
+ * Submitted by: Jake Janovetz <janovetz at tempest.ece.uiuc.edu>
+ *
+ * Changed by: Sergei Organov <osv at javad.ru> (OSV)
+ * Arnout Vandecappelle <arnout at mind.be> (AV)
+ * Sebastien Bourdeauducq <sebastien at milkymist.org> (MM)
+ *
+ *
+ * Changes:
+ *
+ * 2010-12-02 Sebastien Bourdeauducq <sebastien at milkymist.org>
+ *
+ * * Support spaces in filenames
+ *
+ * 2010-04-29 Arnout Vandecappelle (Essensium/Mind) <arnout at mind.be>
+ *
+ * * Added USER/PASS authentication.
+ *
+ * 2001-01-31 Sergei Organov <osv at 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 at 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 at 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 at 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 at 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 at 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 at 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.
