The 'vnet' networking module now uses 192.168.10.3 and bxhub is setting up the
slirp compatible IP 10.0.2.4 for additional services. Added host name "vnet-ftp"
in the DNS code to translate it to the new IP address.
- FTP: handle the hidden flag on Windows the same way as on other platforms.
- TCP/IP: fixed some gcc 9 warnings (checked with Cygwin gcc 9.3).
- DHCP: changed the way to set up the default client IPv4 address.
- Major rewrite of the FTP command handling.
- The LIST command now supports an argument (absolute or relative path).
- Added NLST command (similar to LIST, but file / directory names only).
- The MKD and RMD commands now support absolute paths.
- FTP: added support for renaming file, create and remove directory.
- FTP: added FTP server status report and fixed SYST reply.
- bxhub fix: send all pending packets one after the other.
- TCP fix: when connecting, return default MSS option value 1460.
- TCP fix: handle the case when FIN is set in final data packet.
for the whole file, now the buffer has maximum TCP window size and the file is
read on demand. The directory list is now written to a temporary file that can
be sent with the new code.
- TCP: If a connection is active, forward reset to the service handler.
- FTP: Added support to retrieve the file size.
- FTP: Handle the "file not found" case in RETR and SIZE code.
- FTP: Fixed the logout process.
- TCP: added new method tcpipv4_send_buffer() that can send multiple packets
up to window size without waiting for ACK.
- TCP: when receiving ACK, the data transfer continues if necessary.
- FTP: list contents of root directory (tested on Linux and Win 10 host).
- FTP: added support for file download from root directory (RETR).
- TODO #1: browse directory tree (CWD, CDUP).
- TODO #2: upload file (STOR).
- TODO #3: file and directory commands (SIZE, DELE, MKD, RMD).
- Added packet counter and use it for the IP id field.
- Added support for closing TCP connection from the server side.
- Added FTP passive mode and LIST demo for testing it.
- Some other small changes.
- Partly re-implemented host_to_guest methods from legacy eth_vnet.cc.
- Added two dynamic packet buffers for vnet server replies.
- TFTP and FTP servers are only available if root directory is configured.
- Added TCP port handler methods similar to the UDP ones.
- Added basic TCP connection management and 3-way handshake.
- Added FTP server stub for testing TCP (only login/logout for now).
- Enable packet logging in text format if file name is specified with the
"script" parameter.
- Don't start RX timer if vnet server returns 0.
- Added TCP header structure for future extensions.
- Added DNS service support for the server "vnet" and connected clients.
- Added command line option "-loglev=" to control whether or not there is
BX_ERROR, BX_INFO or BX_DEBUG output. Default value is 1 (BX_ERROR only).
- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved network module base classes and module handling to the Bochs core.
Now loading network driver plugins in netmod.cc.
- Moved shared networking code used by the 'vnet' driver and 'bxhub' from
netmod.cc/.h to new files netutil.cc/.h.
- Created separate plugins for each network driver implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_NETWORK.
