I'm going to do a second 'updated' version of that which rectifies a
couple of more-or-less minor issues with the first one (purpose of
this mail is to document the changes). Specifically,
- the instances_via_skb function should now also compile when
network namespace support is not supposed to be included in
a kernel and the compiler doesn't remove the 'dead code'
before compiling it (Some kernel data structures include a
struct net * unconditionally, some include it only
conditionally. In particular, struct sock and struct
net_device belong to the latter group)
- the nfulnl_recv_config routine now gets the net namespace to
use by examining the ctnl argument since it is kind of
stupid to use the more complicated route via struct skbuff
if a simpler alternative is available
- the unregister_pernet_subsys call has been moved to the end
of nfnetlink_log_fini so that the init and fini codepaths
are again axis-symmetric to each other
NB: Except in the fairly unlikely case that something like an actual
error turns up in this code, I won't send this patch again (or over
and over again :-) because I cannot possibly justify making more
essentially cosmetic changes to something which is working code I need
to solve a specifc problem I've encountered as part of my present job.
