CVS commit: src/sys/net

[Paul Kranenburg <pk%netbsd.org@localhost>]

Module Name:    src
Committed By:   pk
Date:           Fri May 14 13:23:12 UTC 2004

Modified Files:
        src/sys/net: if_tun.c

Log Message:
Fix locking issues noticed by Tom Ivar Helbekkmo on tech-net:
        * always acquire the device instance lock at splnet()
        * missing unlocks in various places

Also, since this driver allows its device instances manipulated by two
independent subsystems (character device & interface clone create/destroy),
be careful not to rip away instance data in a clone destroy request if the
instance is still opened as a character device.
