2008-10-08netfilter: netns nf_conntrack: final netns tweaksAlexey Dobriyan2-63/+114
Add init_net checks to not remove kmem_caches twice and so on. Refactor functions to split code which should be executed only for init_net into one place. ip_ct_attach and ip_ct_destroy assignments remain separate, because they're separate stages in setup and teardown. NOTE: NOTRACK code is in for-every-net part. It will be made per-netns after we decidce how to do it correctly.

2008-10-08netfilter: netns nf_conntrack: per-netns event cacheAlexey Dobriyan4-16/+49
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: Alexey Dobriyan <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>

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: Alexey Dobriyan <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>

2008-10-08netfilter: netns nf_conntrack: per-netns expectationsAlexey Dobriyan11-51/+66
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: Alexey Dobriyan <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>
2008-10-08netfilter: netns: fix {ip,6}_route_me_harder() in netnsAlexey Dobriyan2-4/+5
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: Alexey Dobriyan <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>
2008-10-08netfilter: netns nf_conntrack: per-netns conntrack hashAlexey Dobriyan16-63/+67
* 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.

2008-10-08netfilter: netns nf_conntrack: add ->ct_net -- pointer from conntrack to netnsAlexey Dobriyan3-7/+30
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: Alexey Dobriyan <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>

2008-10-08netfilter: netns: remove nf_*_net() wrappersAlexey Dobriyan7-72/+19
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: Alexey Dobriyan <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>
2008-10-08netfilter: implement NFPROTO_UNSPEC as a wildcard for extensionsJan Engelhardt14-269/+124
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).

2008-10-08netfilter: Introduce NFPROTO_* constantsJan Engelhardt5-25/+37
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.

2008-10-08netfilter: xt_recent: IPv6 supportJan Engelhardt3-54/+256
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: Jan Engelhardt <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>

2008-10-07ipv6: separate seq_ops for global & per/device ipv6 statisticsDenis V. Lunev1-16/+32
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: Denis V. Lunev <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2008-10-07tcp: kill pointless urg_modeIlpo Järvinen5-19/+24
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: Ilpo Järvinen <[email protected]> Signed-off-by: David S. Miller <[email protected]>
