[2.5.65] tun not working

[2.5.65] tun not working

[Jochen Hein]

I'm using tun to connect my virtual S/390 from hercules to the local
machine.  That works pretty well with 2.4, but with 2.5.65 hercules
fails with:

root@gswi1164:~# hercules -f /etc/hercules/hercules.cnf

hercules uses /dev/net/tun to access the tun device.

The module tun is loaded:

dmesg:
Universal TUN/TAP device driver 1.5 (C)1999-2002 Maxim Krasnyansky

root@gswi1164:~# lsmod | grep tun
tun                     6240  0

Any idea why this fails?

Just as a data point, tun itself works for
me on x86 - I use openvpn between my
lan and our remote pop3 server, so I'd
find out in a big hurry if it ever broke -

(currently running 2.5.65 on the vpn gw)

Sounds like a 390-sepecific issue, or
a hercule-specific issue?

With hercules 2.17.1 it works.  Still on kernel 2.5.66.  Hm.
