[uml-devel] 2.4.9-2um

[Jeff D. <jd...@ka...>]

This update features a TUN/TAP backend for the network driver.  

To use it, you:

Make sure the host has TUN/TAP, compiled in, as an autoloaded modules, or
as an already loaded modules, and /dev/net/tun looks like this
	crw-r--r--    1 root     root      10, 200 Jul 20 15:24 tun

Turn on CONFIG_UML_NET_TUNTAP

Grab the latest uml_net if you don't want to be responsible for doing host
setup, and make it look like this:
	-rwsr-xr-x    1 root     root        67902 Aug 28 13:38 /usr/bin/uml_net

Put 'eth0=tuntap,,,192.168.0.254' on the UML command line and let it rip.
The full switch format is eth<n>=tuntap,<device name>,<ether addr>,<TAP IP>,
just like ethertap.  device_name is not currently used.  That's being saved
for persistent TUN/TAP maybe.

From here, it's just like any of the other transports.  Let me know about
any problems.  uml_net isn't as helpful as it is for ethertap yet.  I also
added the ability for uml_net to pass the commands it runs and their output
back to UML which can printk it.  You'll see this when you fire up a tuntap
device.  I think it's an improvement over having random output splatted over
the console.  Let me know if you disagree.

Also, the uml_net bug which shut down ethertap devices it should leave alone
has been fixed.

The hang when UML can't find xterm is fixed.

There is now a nice error when the host is out of ptys.
