2008-04-17[INET]: Uninline the __inet_inherit_port call.Pavel Emelyanov
This deblats ~200 bytes when ipv6 and dccp are 'y'. Besides, this will ease compilation issues for patches I'm working on to make inet hash tables more scalable wrt net namespaces. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-16[GRE]: Use proper net in routing calls.Pavel Emelyanov
As for the IPIP tunnel, there are some ip_route_output_key() calls in there that require a proper net so give one to them. And a proper net for the __get_dev_by_index hanging around. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Everything is prepared for this change now. Create on in init callback, use it over the code and destroy on net exit. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-16[GRE]: Use proper net in hash-lookup functions.Pavel Emelyanov
This is the part#2 of the patch #2 - get the proper net for these functions. This change in a separate patch in order not to get lost in a large previous patch. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-16[GRE]: Add net/gre_net argument to some functions.Pavel Emelyanov
The fallback device and hashes are to become per-net, but many code doesn't have anything to get the struct net pointer from. So pass the proper net there with an extra argument. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-16[IPIP]: Use proper net in (mostly) routing calls.Pavel Emelyanov
There are some ip_route_output_key() calls in there that require a proper net so give one to them. Besides - give a proper net to a single __get_dev_by_index call in ipip_tunnel_bind_dev(). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-16[IPIP]: Make tunnels hashes per net.Pavel Emelyanov
Either net or ipip_net already exists in all the required places, so just use one. Besides, tune net_init and net_exit calls to respectively initialize the hashes and destroy devices. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-16[IPIP]: Use proper net in hash-lookup functions.Pavel Emelyanov

2008-04-16[IPIP]: Add net/ipip_net argument to some functions.Pavel Emelyanov
The hashes of tunnels will be per-net too, so prepare all the functions that uses them for this change by adding an argument.

2008-04-15[TCP]: Remove superflushious skb == write_queue_tail() checkIlpo Järvinen
Needed can only be more strict than what was checked by the earlier common case check for non-tail skbs, thus cwnd_len <= needed will never match in that case anyway. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-15[TCP]: Add return value indication to tcp_prune_ofo_queue().Vitaliy Gusev
Returns non-zero if tp->out_of_order_queue was seen non-empty. This allows tcp_try_rmem_schedule() to return early. Signed-off-by: Vitaliy Gusev <vgusev@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-15[TCP]: Fix never pruned tcp out-of-order queue.Vitaliy Gusev
tcp_prune_queue() doesn't prune an out-of-order queue at all. Therefore sk_rmem_schedule() can fail but the out-of-order queue isn't pruned . This can lead to tcp deadlock state if the next two conditions are held: 1. There are a sequence hole between last received in order segment and segments enqueued to the out-of-order queue. 2. Size of all segments in the out-of-order queue is more than tcp_mem[2]. Signed-off-by: Vitaliy Gusev <vgusev@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-14[NETFILTER]: nf_nat: kill helper and seq_adjust hooksPatrick McHardy
Connection tracking helpers (specifically FTP) need to be called before NAT sequence numbers adjustments are performed to be able to compare them against previously seen ones. We've introduced two new hooks around 2.6.11 to maintain this ordering when NAT modules were changed to get called from conntrack helpers directly. The cost of netfilter hooks is quite high and sequence number adjustments are only rarely needed however. Add a RCU-protected sequence number adjustment function pointer and call it from IPv4 conntrack after calling the helper. Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_nat: don't add NAT extension for confirmed conntracksPatrick McHardy
Adding extensions to confirmed conntracks is not allowed to avoid races on reallocation. Don't setup NAT for confirmed conntracks in case NAT module is loaded late. The has one side-effect, the connections existing before the NAT module was loaded won't enter the bysource hash. The only case where this actually makes a difference is in case of SNAT to a multirange where the IP before NAT is also part of the range. Since old connections don't enter the bysource hash the first new connection from the IP will have a new address selected. This shouldn't matter at all.

2008-04-14[NETFILTER]: nf_nat: remove obsolete check for ICMP redirectsPatrick McHardy
Locally generated ICMP packets have a reference to the conntrack entry of the original packet manually attached by icmp_send(). Therefore the check for locally originated untracked ICMP redirects can never be true. Signed-off-by: Patrick McHardy <kaber@trash.net>

2008-04-14[NETFILTER]: Add partial checksum validation helperPatrick McHardy
Move the UDP-Lite conntrack checksum validation to a generic helper similar to nf_checksum() and make it fall back to nf_checksum() in case the full packet is to be checksummed and hardware checksums are available. This is to be used by DCCP conntrack, which also needs to verify partial checksums. Signed-off-by: Patrick McHardy <kaber@trash.net>
