  • rtems_servers/ftpd.c, rtems_servers/ftpd.h: Major enhancements as listed below:
    • use pool of pre-created threads to handle sessions instead of

creating/deleting threads on the fly

  • LIST output is now similar to what "/bin/ls -al" would output, thus FTP clients such Netscape are happy with it.
  • LIST NAME now works (both for files and directories)
  • added support for NLST, CDUP, and MDTM FTP commands to make more FTP clients happy
  • keep track of CWD for every session separately
  • ability to specify root directory name for FTPD in configuration table. FTPD will then create illusion for FTP clients that this is actually root directory.
  • ignore options sent in commands, thus LIST -al FILE works and doesn't try to list "-al" directory.
  • buffers are allocated on stack instead of heap where possible to eliminate malloc/free calls (avoid possible heap fragmentation troubles).
  • drop using of task notepad to pass parameters - use function arguments instead
  • use snprintf() instead of sprintf() as the latter is unsafe
  • use of PF_INET in socket() instead of AF_INET

Here are ftp clients I've tried new FTPD with (all of them
running on Debian GNU/Linux 2.2):

Lftp 2.1.10
NcFTP 2.4.3
Netscape 4.75
ftp
mc 4.5.49
