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: NAlexey Dobriyan <adobriyan@gmail.com> Signed-off-by: NPatrick McHardy <kaber@trash.net>

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: NAlexey Dobriyan <adobriyan@gmail.com> Signed-off-by: NPatrick McHardy <kaber@trash.net>

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: NAlexey Dobriyan <adobriyan@gmail.com> Signed-off-by: NPatrick McHardy <kaber@trash.net>

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: NAlexey Dobriyan <adobriyan@gmail.com> Signed-off-by: NPatrick McHardy <kaber@trash.net>

* 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.

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: NAlexey Dobriyan <adobriyan@gmail.com> Signed-off-by: NPatrick McHardy <kaber@trash.net>

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.

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: NDenis V. Lunev <den@openvz.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

It all started from me noticing that this urgent check in tcp_clean_rtx_queue is unnecessarily inside the loop. Then I took a longer look to it and found out that the users of urg_mode can trivially do without, well almost, there was one gotcha. Bonus: those funny people who use urg with >= 2^31 write_seq - snd_una could now rejoice too (that's the only purpose for the between being there, otherwise a simple compare would have done the thing). Not that I assume that the rest of the tcp code happily lives with such mind-boggling numbers :-). Alas, it turned out to be impossible to set wmem to such numbers anyway, yes I really tried a big sendfile after setting some wmem but nothing happened :-). ...Tcp_wmem is int and so is sk_sndbuf... So I hacked a bit variable to long and found out that it seems to work... :-) Signed-off-by: NIlpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
