as i've written in a previously mail this is the checkentry function
that i use in my source code to check if the iptables command line is
a right line.

[CHECK_ENTRY_CODE]
static bool xt_tarpit_check(const char *tablename, const void *entry,
                           const struct xt_target *target, void *targinfo,
                           unsigned int hook_mask)
{
 if (strcmp(tablename, "filter"))   {
   printk(KERN_INFO "DEBUG: the tablename (not FILTER) is %s\n",tablename);
   return false;
 }
return true;
}
[/CHECK_ENTRY_CODE]

but it doesn't work...NOTE: the module goes inside the function but
the tablename value is a wrong one (also if I set "-t filter" option
in the iptables command line)

i don't know what "static int hashlimit_mt_check(const struct
xt_mtchk_param *par)" is...

thank you
