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.
- Reset FTP session state in case of login failure.
- Improved FTP server status output.
- Added special error messages for 2 unimplemented commands.
- Updated vnet / socket / slirp networking module infos in source and docs.
- 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.
- 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).
- 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).
NOTE: networking still fails when compiled with Cygwin ('socket' mode fails
to set up non-blocking i/o / 'slirp' doesn't complain, but fails to connect
the internet).
- 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.
The format of the 'ethdev' string must be 'host:port' to use this feature.
Using the port number only for connecting 'bxhub' on the same machine is still
supported.
- Increase maximum number of Bochs client sessions to 6.
- Define bx_devmodel_c to 'void' for the bxhub case to simplify netmod code.
- Minor cleanups in bxhub and related vnet code.
- eth_socket.cc: Added missing winsock init.
- bxhub.cc: Added missing CDECL macro to the signal handler.
- Added some definitions for non-Windows platforms similar to the serial and
rfb code.
- bxhub.cc: Put all client data in a structure and added send_packet() function.
- bxhub.cc: Added SVN ID line.
- netmod.cc: Changed some DHCP messages to BX_DEBUG.
- eth_socket.cc: Minor cleanups.
external program 'bxhub' (simulating a two port ethernet hub). It is based on
an old SF patch and it has been updated and extended:
- Windows support (tested with MinGW/MSYS and MSVC nmake).
- Command line arguments for 'bxhub' (base port number, MAC address, TFTP).
- Added support for DHCP, TFTP, ARP and ICMP echo (ping). It uses parts of the
code for the 'vnet' module with some additions from the former "slirp backend".
- TODO: code cleanup to reduce duplication, rewrite of the networking plugins
stuff similar to the work done with the sound drivers.
