File descriptor in bad state...again ;-(

[Martin Rusko]

OK, I did compile tinc-1.0pre7-2 from debian sources (the same version 
is used in woody/stable distribution, which is installed on all 
machines) against kernel sources of my current running kernel (2.4.18 
from debian kernel-source package). I have to say, that doing so, have 
no point for me (why?), because woody has kernel 2.4.18, and I have also 
kernel 2.4.18 (I needed quota v2 support). But I did it. And of course, 
it didn't help. ;-(

What I don't understand is, how the same module (tun.o), from the same 
kernel version 2.4.18, has different sizes?

On Sunclient with original debian kernel 2.4.18:
# ls -l /lib/modules/2.4.18/kernel/drivers/net/tun.o
-rw-r--r--    1 root     root        10256 Apr 11  2002 
/lib/modules/2.4.18/kernel/drivers/net/tun.o

On Sunsite with patched kernel 2.4.18 with quota support:
-rw-r--r--    1 root     root         9784 Nov  4 15:49 
/lib/modules/2.4.18/kernel/drivers/net/tun.o

Also, if you will have some time, please see attached strace output, 
maybe you will know, what is happening.

         Any help will be very appreciated
