- 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.
- Fixed ne2k parameter save function.
- For backward compatibility, card #0 defaults to PCI if the ne2k is assigned
to at least one PCI slot.
- The "bootrom" parameter is only valid for the PCI card type.
old SF patches this solution is compatible with the plugin architecture. The
ne2k plugin is loaded only once and a new ne2k_main_c object creates up to 4
ne2k device objects depending on the config. The new ne2k parameter "card"
specifies the zero-based card number to configure. If not given, the default
is card #0 for compatibility. The new ne2k parameter "type" specifies the bus
it is connected to ("isa" or "pci"). Card #0 defaults to PCI, the others to
ISA. In the PCI slot configuration the ne2k device can be used multiple times
if more than one card is configured.
Related changes:
- removed SMF stuff for ne2k
- always convert device prefix to uppercase (ne2k uses NE2K0 ... NE2K3)
- removed unused BXPN values
- TODO: add multiple NICs support for the E1000
- The pthread library is not needed at all by the Windows ports.
- Link the ALSA and SDL sound modules only with required library.
- Fixed curses cross-compilation issue found by Debian.
- slirp/cksum.cc: NOTE for Debian.
- configure script now supports wxGTK 3.1 (using GTK 3.0).
- added workaround for GDK keysym name change.
- define deprecated WXWIN symbol wxADJUST_MINSIZE for compatibility.
- compilation fix for Linux in the slirp code.
- Added INT pin init to method init_pci_conf().
- Moved readonly register handling to the common PCI write handler.
- Moved IRQ line reporting to the common PCI write handler.
- Added new structure bx_pci_bar_t that contains all parameters related to the
PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
BARs and the ROM BAR. Writes to other registers are forwarded to the device
specific PCI write handlers. Removed BAR and ROM BAR handling from the
specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.
- Added support for setting memory write handler to NULL (ROM case).
- Added new PCI device method after_restore_pci_state(). It currently handles
the PCI ROM case only (could be extended).
- 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).
- Enabled Winsock2 usage and define _WIN32 symbol for Cygwin (both 32 and 64 bit).
- Changed include order in some files to resolve conflicts.
- Modified some data types to fix errors and warnings.
- Added workarounds for the incorrectly defined symbols FIONBIO, FIONREAD and
EWOULDBLOCK.
- Verified slirp usability with Cygwin 32-bit, MinGW/MSYS and MSVC builds of
Bochs. Other ports should not be affected.
- socket: Define the FIONBIO workaround for 64-bit Cygwin only.
- slirp: Don't mix usage of WIN32 and _WIN32 definitions.
- TODO: The slirp module still fails at UDP socket creation when Bochs is
compiled in Cygwin64.
- slirp: Increment IP packet ID outside of htons() to avoid undefined behaviour.
- socket: Workaround for a bug in the w32api code that generates a constant
with wrong value. Setting up our own FIONBIO fixes the panic.
- TODO: The slirp module still fails when Bochs is compiled in Cygwin64.
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).
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.
- Since the pci_read_handler() method is identical in most devices, move it
to the base class to reduce code duplication. Only the 'pcidev' device has
it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.
- In "non-plugin" mode loading and unloading network module is not necessary.
Now enabled loading for the plugin mode only and removed unloading function
for that case. The "pseudo plugin" entries of the dummy entry points are
necessary to make sure the self-registering network driver objects are not
optimized out.
- slirp / vnet: Since the plugin init function is not called in non-plugin
mode, revert the instance count init change.
- Fixed a makefile dependecy.
- TODO: Implement self-registering objects in the sound driver code.
- 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.
