Heh, last minute proof-reading of this patch made me think, that this is actually unneeded, simply because "ct" pointers will be different for different conntracks in different netns, just like they are different in one netns. Not so sure anymore. [Patrick: pointers will be different, flushing can only be done while inactive though and thus it needs to be per netns] Signed-off-by:

Conntrack code will use it for a) removing expectations and helpers when corresponding module is removed, and b) removing conntracks when L3 protocol conntrack module is removed. Signed-off-by:

Again, it's deducible from skb, but we're going to use it for nf_conntrack_checksum and statistics, so just pass it from upper layer. Signed-off-by:

It's deducible from skb->dev or skb->dst->dev, but we know netns at the moment of call, so pass it down and use for finding and creating conntracks. Signed-off-by:

Make per-netns a) expectation hash and b) expectations count. Expectations always belongs to netns to which it's master conntrack belong. This is natural and doesn't bloat expectation. Proc files and leaf users are stubbed to init_net, this is temporary. Signed-off-by:

Take netns from skb->dst->dev. It should be safe because, they are called from LOCAL_OUT hook where dst is valid (though, I'm not exactly sure about IPVS and queueing packets to userspace). [Patrick: its safe everywhere since they already expect skb->dst to be set] Signed-off-by:

* make per-netns conntrack hash Other solution is to add ->ct_net pointer to tuplehashes and still has one hash, I tried that it's ugly and requires more code deep down in protocol modules et al. * propagate netns pointer to where needed, e. g. to conntrack iterators. Signed-off-by:

Conntrack (struct nf_conn) gets pointer to netns: ->ct_net -- netns in which it was created. It comes from netdevice. ->ct_net is write-once field. Every conntrack in system has ->ct_net initialized, no exceptions. ->ct_net doesn't pin netns: conntracks are recycled after timeouts and pinning background traffic will prevent netns from even starting shutdown sequence. Right now every conntrack is created in init_net. Signed-off-by:

Now that dev_net() exists, the usefullness of them is even less. Also they're a big problem in resolving circular header dependencies necessary for NOTRACK-in-netns patch. See below. Signed-off-by:

When a match or target is looked up using xt_find_{match,target}, Xtables will also search the NFPROTO_UNSPEC module list. This allows for protocol-independent extensions (like xt_time) to be reused from other components (e.g. arptables, ebtables). Extensions that take different codepaths depending on match->family or target->family of course cannot use NFPROTO_UNSPEC within the registration structure (e.g. xt_pkttype).

The netfilter subsystem only supports a handful of protocols (much less than PF_*) and even non-PF protocols like ARP and pseudo-protocols like PF_BRIDGE. By creating NFPROTO_*, we can earn a few memory savings on arrays that previously were always PF_MAX-sized and keep the pseudo-protocols to ourselves. Signed-off-by:

This updates xt_recent to support the IPv6 address family. The new /proc/net/xt_recent directory must be used for this. The old proc interface can also be configured out. Signed-off-by:

idev has been stored on seq->private. NULL has been stored for global statistics. The situation is changed with net namespace. We need to store pointer to struct net and the only place is seq->private. So, we'll have for /proc/net/dev_snmp6/* and for /proc/net/snmp6 pointers of two different types stored in the same field. This effectively requires to separate seq_ops of these files. Signed-off-by:
