a869dcdf6d Terminology clarification: "emulated host" is nowadays "guest"... 
and it is running on the "host". The used term "emulated host" (as opposed to "hardware host") is somewhat confusing.

09ee2e73c8 This may well have been the cause of the shutdown problems of dpni20. 2017-01-21 23:29:15 +01:00

2945263432 For the ni20, add subcommands to the "dev ni0 ..." command. 
This may be useful for debugging, given the subcommands as currently made available.
The main loop command line parser is used to parse the subcommands. I don't think this is working for interactive subcommands yet.

d218e5b03f Replace 0600 in shmget(2) call with symbolic constants. 
Inspired by Rich Alderson's MacOS 10.6.8 changes.
He used IPC_CREAT+IPC_PRIVATE+IPC_R+IPC_W.
However, IPC_PRIVATE is a special value for the key argument, not shmflg.
Furthermore, adding IPC_CREAT to the flags when the key is IPC_PRIVATE
seems unnecessary but should not harm.

See http://pubs.opengroup.org/onlinepubs/9699919799/functions/shmget.html
for the "IEEE Std 1003.1-2008, 2016 Edition" version of shmget(2).

bf51af5874 Make a string available that indicates the supported networking options. 
dpni20 and dpimp print it on error or when -debug is given.
enaddr prints it with -v, but this does not reflect TUN since it doesn't use it.

4075a69ccb Try harder to get printf formats right for some typedef'ed types. 
For older versions of clang that's still not enough and they keep complaining,
but for newer ones it's ok.

563368b75b Implement QUIT messages to IMP and NI20 
so that they can do cleanup at the end: mostly important for tun, tap,
and bridge that may have been created.

1a512d7628 More HAVE_MLOCKALL. 2016-01-25 23:08:02 +01:00
Olaf Seibert
162cf21aca Changed the check for superuser from error to warning. 
The check is done so early that we can't reasonably know yet if we really
need to be root. For VDE, root is unneeded, but for the other interface
methods it is.

3830fca3f9 Ether address and multicast setting for MacOS X. 2016-01-25 22:12:00 +01:00

223c7b4698 Start using CPPFLAGS and use it for the -I options. 
This avoids sloppy messages from the configure script about the preprocessor.

105ec2c0a8 Use configure for mlockall(2). 
The set of OSes for was inconsistent and wrong (NetBSD has it too).

03be37db7c Add initial VDE (libvde2) support. 
I have compile-tested this on a virtual FreeBSD 10.2 but not run it.

334719e73a Make it build on MacOS X. 
I only compile-tested it, I didn't run it.
The main effect is to make hardware tape support ~optional, since OSX
has no <sys/mtio.h>.

2ac5184ff2 Add a configure script and remove a tangle of frail #if conditions 
This only uses autoconf, not automake or libtool or intltool or whatever.
This also allows easy building of different emulators in different build directories.

I have tested TOPS-20 with pcap|tap+bridge, ITS with pcap|tun|tap+bridge, both on NetBSD and Linux
and hopefully everything still works after the fine-tuning.

447155ef02 Remove bridge creating code for Linux, since it's useless. 
If $KLH_NET_BRIDGE is set, does bridge it to that bridge.
Use $KLH_NET_DEFAULT_IF as default interface, if given.

10023a5e18 Added Linux tap+bridge, plus other cleanups. 
However it turns out that Linux bridges are useless, since they freeze
the network when they are actually used (see http://www.microhowto.info/troubleshooting/troubleshooting_ethernet_bridging_on_linux.html#idp86992 )
"The machine appears to freeze
As noted above, adding an interface to a bridge causes it to
stop acting as an Internet Protocol endpoint. This could result
in the machine appearing to freeze.

"The underlying issue is that when an interface is attached to
a bridge then any network addresses need to be bound to the
bridge, not to the interface."

That makes them useless to configure temporarily without disturbing
the rest of the network traffic.
