Simulation context switching is based on logic like setjmp and longjmp. This

context switching is only available for 32-bit targets. On 64-bit machines,

this context switching will fail.

The workaround on 64-bit machines for now is to build for a 32-bit target on the

|
2020-02-23 09:50:23 +01:00

beyond. For those versions, you must add SIM_M32=y to the .config file in

SUMMARY
-------
This patch enhances networking support for the simulation under Linux.
Includes updated support for Linux TUN/TAP, and the addition of support for
Linux bridge devices.
CHANGES
-------
o Check to see if the d_txavail callback is present before calling it in
the arp send code. This prevents a segfault when simulating the telnetd
daemon with arp send enabled.
o Adjust the simulation's netdriver_loop() so it will detect and respond to
ARP requests.
o Do not attempt to take the tap device's hardware address for use by the
simulation. That hardware address belongs to the host end of the link,
not the simulation end. Generate a randomized MAC address instead.
o Do not assign an IP address to the interface on the host side of the TAP
link.
+ Provide two modes: "host route" and "bridge".
+ In host route mode, maintain a host route that points any traffic for the
simulation's IP address to the tap device. In this mode, so long as the
simulation's IP is a free address in the same subnet as the host, no
additional configuration will be required to talk to it from the host.
Note that address changes are handled automatically if they follow the
rule of if-down/set-address/if-up, which everything seems to.
+ In bridge mode, add the tap device to the specified bridge instance. See
configs/sim/NETWORK-LINUX.txt for information and usage examples. This
enables much more flexible configurations (with fewer headaches), such as
running multiple simulations on a single host, all of which can access
the network the host is connected to.
o Refresh configurations in configs/sim where CONFIG_NET=y. They default
to "host route" mode.
o Add configs/sim/NETWORK-LINUX.txt
CAVEATS
-------
- The MAC address generation code is extremely simplistic, and does not
check for potential conflicts on the network. Probably not an issue, but
something to be aware of.
- I was careful to leave it in a state where Cygwin/pcap should still work,
but I don't have a Windows environment to test in. This should be
checked.
- I don't know if this was ever intended to work with OS X. I didn't even
try to test it there.
NOTES
-----
- Was able to get telnetd working and simulate nsh over telnet, but only so
long as listen backlogs were disabled.
There appears to be a bug in the backlog code where sockets are being
returned in SYN_RCVD state instead of waiting until they're ESTABLISHED;
if you perform an immediate send after accepting the connection, it will
confuse the stack and the send will hang; additionally, the connection
will never reach ESTABLISHED state.
Can be worked around by adding a sleep(1) after the accept in telnetd. I
don't have the necessary knowledge of the IP stack to know what the
correct fix is.

something to be aware of.
- I was careful to leave it in a state where Cygwin/pcap should still work,
but I don't have a Windows environment to test in. This should be
checked.
- I don't know if this was ever intended to work with OS X. I didn't even
try to test it there.
NOTES
-----
- Was able to get telnetd working and simulate nsh over telnet, but only so
long as listen backlogs were disabled.
There appears to be a bug in the backlog code where sockets are being
returned in SYN_RCVD state instead of waiting until they're ESTABLISHED;
if you perform an immediate send after accepting the connection, it will
confuse the stack and the send will hang; additionally, the connection
will never reach ESTABLISHED state.
Can be worked around by adding a sleep(1) after the accept in telnetd. I
don't have the necessary knowledge of the IP stack to know what the
correct fix is.

SUMMARY
-------
This patch enhances networking support for the simulation under Linux.
Includes updated support for Linux TUN/TAP, and the addition of support for
Linux bridge devices.
CHANGES
-------
o Check to see if the d_txavail callback is present before calling it in
the arp send code. This prevents a segfault when simulating the telnetd
daemon with arp send enabled.
o Adjust the simulation's netdriver_loop() so it will detect and respond to
ARP requests.
o Do not attempt to take the tap device's hardware address for use by the
simulation. That hardware address belongs to the host end of the link,
not the simulation end. Generate a randomized MAC address instead.
o Do not assign an IP address to the interface on the host side of the TAP
link.
+ Provide two modes: "host route" and "bridge".
+ In host route mode, maintain a host route that points any traffic for the
simulation's IP address to the tap device. In this mode, so long as the
simulation's IP is a free address in the same subnet as the host, no
additional configuration will be required to talk to it from the host.
Note that address changes are handled automatically if they follow the
rule of if-down/set-address/if-up, which everything seems to.
+ In bridge mode, add the tap device to the specified bridge instance. See
configs/sim/NETWORK-LINUX.txt for information and usage examples. This
enables much more flexible configurations (with fewer headaches), such as
running multiple simulations on a single host, all of which can access
the network the host is connected to.
o Refresh configurations in configs/sim where CONFIG_NET=y. They default
to "host route" mode.
o Add configs/sim/NETWORK-LINUX.txt
CAVEATS
-------
- The MAC address generation code is extremely simplistic, and does not
check for potential conflicts on the network. Probably not an issue, but
something to be aware of.
- I was careful to leave it in a state where Cygwin/pcap should still work,
but I don't have a Windows environment to test in. This should be
checked.

Attach a Linux I2C bus via the character device

interface. This should be used with caution as it

could interfere with devices internal to the system.

It is recommended to use this with a USB<>I2C device

like the MCP2221 and set udev rules so that only

the bus provided by this device can be controlled

by the user running the simulator.

Under simulation, a NuttX port can be bound to a serial
|
|
|
|
port on the host machine. This way NuttX can access the
|
|
|
|
host's hardware directly.
|
2022-11-22 09:13:36 +01:00
|
|
|
|
2022-01-20 18:18:56 +01:00
|
|
|
There are two possibilities regarding the host's port:
|
|
|
|
it can be either a physical one, or a simulated one.
|
2022-11-22 09:13:36 +01:00
|
|
|
|
2022-01-20 18:18:56 +01:00
|
|
|
In case of a physical port, NuttX will be able to open
|
|
|
|
this port and communicate with any actual hardware that
|
|
|
|
it is connected to. This is useful for testing code that
|
|
|
|
uses external hardware (e.g. sensors or other boards).
|
|
|
|
In order for this to work, NuttX port name must be set to
|
|
|
|
the same name that the host is using for this port (e.g.
|
|
|
|
/dev/ttyUSB0).
|
2022-11-22 09:13:36 +01:00
|

|
2022-01-20 18:18:56 +01:00
|
|
|
Alternativelly, a "simulated" host port may be used to.
|
|
|
|
This is useful if you need to also simulate the external
|
|
|
|
hardware, or to have NuttX communicate with any other
|
|
|
|
software in your system.
|
|
|
|
You can create a "simulated" port in your host,
|
|
|
|
by running:
|
2022-11-22 09:13:36 +01:00
|
|
|
|
2022-01-20 18:18:56 +01:00
|
|
|
socat PTY,link=/dev/ttySIM0 PTY,link=/dev/ttyNX0
|
2023-05-09 15:26:24 +02:00
|
|
|
stty -F /dev/ttySIM0 raw
|
|
|
|
stty -F /dev/ttyNX0 raw
|

|
|
|
|
2022-01-20 18:18:56 +01:00
|
|
|
This will create two new ports on your system.
|
|
|
|
NuttX will use the ttySIM0 port, and another software
|
|
|
|
may open and use the ttyNX0 port.
|
|
|
|
Anything sent to the one of these ports will be relayed
|
|
|
|
automatically to the other, and vice-versa.
