The XQ emulator is a host-independant software emulation of Digital's

||||
The Sim_Ether module sets the selected Ethernet card into
|
||||
promiscuous mode to gather all packets, then filters out the packets that it
|
||||
doesn't want. In Windows, packets having the same source MAC address as the
|
||||
controller are ignored for WinPCAP compatibility (see Windows notes below).

If your ethernet card is plugged into a switch, the promiscuous mode setting
|
||||
If your Ethernet card is plugged into a switch, the promiscuous mode setting
|
||||
should not cause much of a problem, since the switch will still filter out
|
||||
most of the undesirable traffic. You will only see "excessive" traffic if you
|
||||
are on a direct or hub(repeater) segment.
|
||||
|
||||
Using the libpcap/WinPcap interface, the simulated computer cannot "talk" to
|
||||
the host computer via the selected interface, since the packets are not
|
||||
reflected back to the host. The workaround for this is to use a second NIC in
|
||||
the host and connect them both into the same network; then the host and the
|
||||
simulator can communicate over the physical LAN.
|
||||
On Windows using the WinPcap interface, the simulated computer can "talk" to
|
||||
the host computer on the same interface. On other platforms with libpcap
|
||||
(*nix), the simulated computer can not "talk" to the host computer via the
|
||||
selected interface, since simulator transmitted packets are not received
|
||||
by the host's network stack. The workaround for this is to use a second NIC
|
||||
in the host and connect them both into the same network; then the host and
|
||||
the simulator can communicate over the physical LAN.
|
||||
|
||||
Universal TUN/TAP support provides another solution for the above dual-NIC
|
||||
problem for systems that support Universal TUN/TAP. Since the TUN/TAP interface
|
||||
is at a different network level, the host can create a TAP device for the
|
||||
simulator and then bridge or route packets between the TAP device and the real
|
||||
network interface. Note that the TAP device and any bridging or routing must be
|
||||
established before running the simulator; SIMH does not create, bridge, or
|
||||
route TAP devices for you.
|
||||
Integrated Universal TUN/TAP support provides another solution for the above
|
||||
dual-NIC problem for systems that support Universal TUN/TAP. Since the TUN/TAP
|
||||
interface is a pseudo network interface, the host can create a TAP device for
|
||||
the simulator and then bridge or route packets between the TAP device and the
|
||||
real network interface. Note that the TAP device and any bridging or routing
|
||||
must be established before running the simulator; SIMH does not create,
|
||||
bridge, or route TAP devices for you.
|
||||
|
||||
Integrated Universal TUN/TAP support can be used for host<->simulator network
|
||||
traffic (on the platforms where it is available) by using the SIMH command:
|
||||
"attach xq tap:tapN" (i.e. attach xq tap:tap0). Platforms that this has been
|
||||
tested on include: Linux, FreeBSD, OpenBSD, NetBSD. Each of these platforms
|
||||
has some way to create a tap pseudo device and then bridge it with a physical
|
||||
network interface.

enabled which is expected to implement the checksum computations
|
||||
in hardware. Since we catch packets before they arrive at the
|
||||
NIC the expected checksum insertions haven't been performed yet.
|
||||
This processing is only done for packets sent from the host to
|
||||
the guest we're supporting. In general this will be a relatively
|
||||
small number of packets so it is done for all IP frame packets
|
||||
coming from the host to the guest. In order to make the
|
||||
determination of packets specifically arriving from the host we
|
||||
need to know the hardware MAC address of the host NIC. Currently
|
||||
determining a NIC's MAC address is relatively easy on Windows.
|
||||
The non-windows code works on linux and may work on other *nix
|
||||
platforms either as is or with slight modifications. The code,
|
||||
as implemented, only messes with this activity if the host
|
||||
interface MAC address can be determined.
|
||||
20-May-10 MP Added general support to deal with receiving packets smaller
|
||||
than ETH_MIN_PACKET in length. These come from packets
|
||||
looped back by some bridging mechanism and need to be padded
|
||||
to the minimum frame size. A real NIC won't pass us any
|
||||
packets like that. This fix belongs here since this layer
|
||||
is responsible for interfacing to the physical layer
|
||||
devices, AND it belongs here to get CRC processing right.
|
||||
15-Aug-08 MP Fixed transmitted packets to have the correct source MAC address.
|
||||
Fixed incorrect address filter setting calling eth_filter().
|
||||
07-Mar-08 MP Fixed the SCP visible SA registers to always display the
|
||||
ROM MAC address, even after it is changed by SET XQ MAC=.
|
||||
07-Mar-08 MP Added changes so that the Console DELQA diagnostic (>>>TEST 82)
|
||||
will succeed.
|
||||
03-Mar-08 MP Added DELQA-T (aka DELQA Plus) device emulation support.
|
||||
06-Feb-08 MP Added dropped frame statistics to record when the receiver discards
|
||||
received packets due to the receiver being disabled, or due to the
|
||||
XQ device's packet receive queue being full.
|
||||
Fixed bug in receive processing when we're not polling. This could
|
||||
cause receive processing to never be activated again if we don't
|
||||
read all available packets via eth_read each time we get the
|
||||
opportunity.
|
||||
31-Jan-08 MP Added the ability to Coalesce received packet interrupts. This
|
||||
is enabled by SET XQ POLL=DELAY=nnn where nnn is a number of
|
||||
microseconds to delay the triggering of an interrupt when a packet
|
||||
is received.
|
||||
29-Jan-08 MP Added SET XQ POLL=DISABLE (aka SET XQ POLL=0) to operate without
|
||||
polling for packet read completion.
|
||||
29-Jan-08 MP Changed the sanity and id timer mechanisms to use a separate timer
|
||||
unit so that transmit and receive activities can be dealt with
|
||||
by the normal xq_svc routine.
|
||||
Dynamically determine the timer polling rate based on the
|
||||
calibrated tmr_poll and clk_tps values of the simulator.
|
||||
25-Jan-08 MP Enabled the SET XQ POLL to be meaningful if the simulator currently
|
||||
doesn't support idling.
|
||||
25-Jan-08 MP Changed xq_debug_setup to use sim_debug instead of printf so that
|
||||
all debug output goes to the same place.
|
||||
25-Jan-08 MP Restored the call to xq_svc after all successful calls to eth_write
|
||||
to allow receive processing to happen before the next event
|
||||
service time. This must have been inadvertently commented out
|
||||
while other things were being tested.
|
||||
23-Jan-08 MP Added debugging support to display packet headers and packet data
|
||||
18-Jun-07 RMS Added UNIT_IDLE flag
|
||||
29-Oct-06 RMS Synced poll and clock

|
||||

|
||||
|
||||
05-Mar-08 MP Added optional multicast filtering support for doing
|
||||
LANCE style AUTODIN II based hashed filtering.
|
||||
07-Feb-08 MP Added eth_show_dev to display Ethernet state
|
||||
Changed the return value from eth_read to return whether
|
||||
or not a packet was read. No existing callers used or
|
||||
checked constant return value that previously was being
|
||||
supplied.
|
||||
29-Jan-08 MP Added eth_set_async to provide a mechanism (when
|
||||
USE_READER_THREAD is enabled) to allow packet reception
|
||||
to dynamically update the simulator event queue and
|
||||
potentially avoid polling for I/O. This provides a minimal
|
||||
overhead (no polling) maximal responsiveness for network
|
||||
activities.
|
||||
29-Jan-08 MP Properly sequenced activities in eth_close to avoid a race
|
||||
condition when USE_READER_THREAD is enabled.
|
||||
25-Jan-08 MP Changed the following when USE_READER_THREAD is enabled:
|
||||
- Fixed bug when the simulated device doesn't need crc
|
||||
in packet data which is read.
|
||||
- Added call to pcap_setmintocopy to minimize packet
|
||||
delivery latencies.
|
||||
- Added ethq_destroy and used it to avoid a memory leak in
|
||||
eth_close.
|
||||
- Properly cleaned up pthread mutexes in eth_close.
|
||||
Migrated to using sim_os_ms_sleep for a delay instead of
|
||||
a call to select().
|
||||
Fixed the bpf filter used when no traffic is to be matched.
|
||||
Reworked eth_add_packet_crc32 implementation to avoid an
|
||||
extra buffer copy while reading packets.
|
||||
Fixed up #ifdef's relating to USE_SHARED so that setting
|
||||
USE_SHARED or USE_NETWORK will build a working network
|
||||
environment.
|
||||
23-Jan-08 MP Reworked eth_packet_trace and eth_packet_trace_ex to allow
|
||||
only output Ethernet header+crc and provide a mechanism for
|
||||
the simulated device to display full packet data debugging.
|
||||
17-May-07 DTH Fixed non-Ethernet device removal loop (from Naoki Hamada)
|
||||
15-May-07 DTH Added dynamic loading of wpcap.dll;
|
||||
Corrected exceed max index bug in ethX lookup
|
||||
04-May-07 DTH Corrected failure to look up Ethernet device names in
|
||||
the registry on Windows XP x64
|
||||
10-Jul-06 RMS Fixed linux conditionalization (from Chaskiel Grundman)
|
||||
02-Jun-06 JDB Fixed compiler warning for incompatible sscanf parameter

||||
(from Mark Pizzolato and Galen Tackett, 08-Jun-05)
|
||||
Patched eth_open [tun fix](from Antal Ritter, 06-Oct-05)
|
||||
30-Nov-05 DTH Added option to regenerate CRC on received packets; some
|
||||
Ethernet devices need to pass it on to the simulation, and by
|
||||
the time libpcap/winpcap gets the packet, the host OS network
|
||||
layer has already stripped CRC out of the packet
