Hello Rusty,
Isn't there a module race possible with the netfilter function nf_sockopt (net/core/netfilter.c)? This function calls the sockopt function of a registered netfilter module, like iptables. F.e. the function do_ipt_set_ctl in ip_tables.c could be called. What if the iptables module is being unloaded on one cpu, while another cpu just called do_ipt_set_ctl? I think there needs to be a try_module_get and module_put in the nf_sockopt function to handle this. What do you think?
-- cheers, Bart
