6cefbc0c3f This change provides an option to add /dev/urandom to all architectures. The pseudo-random algorithm I choose strikes an arguably-good balance between being "random" and small/fast enough for 8/16 bit MCUs. It’s the well-documented xorshift128 algorithm. It has an internal state of 128 bits that can be [re-]seeded with a write. 2016-07-17 06:42:26 -06:00

bd3ef36eda 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.
