[Nicola Padovano]

Hi all. How can I export the secure_tcp_sequence_number to use it in my modules?

If i attempt to insert the module that uses the
secure_tcp_sequence_number i get this error message:

from insmod:  -1 Invalid module format
and from dmesg: version magic '2.6.35.4 SMP mod_unload 586 ' should be
'2.6.35.4 SMP mod_unload modversions 586 '

what's the matter?
