* [NETNS][IPV6] flowlabels - make flowlabels per namespaceBenjamin Thery2008-03-261-16/+56
| | | | | | | | | This patch introduces a new member, fl_net, in struct ip6_flowlabel. This allows to create labels with the same value in different namespaces.

* [IPV6]: Fix potential net leak and oops in ipv6 routing code.Pavel Emelyanov2008-03-261-2/+20
| | | | | | | | | | | | | | | | The commits f3db4851 ([NETNS][IPV6] ip6_fib - fib6_clean_all handle several network namespaces) and 69ddb805 ([NETNS][IPV6] route6 - Make proc entry /proc/net/rt6_stats per namespace) made some proc files per net. Both of them introduced potential OOPS - get_proc_net can return NULL, but this check is lost - and a struct net leak - in case single_open() fails the previously got net is not put. Kill all these bugs with one patch. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Acked-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* [VLAN]: Reduce memory consumed by vlan_groupsPavel Emelyanov2008-03-261-13/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently each vlan_groupd contains 8 pointers on arrays with 512 pointers on struct net_device each :) Such a construction "in many cases ... wastes memory". My proposal is to allow for some of these arrays pointers be NULL, meaning that there are no devices in it. When a new device is added to the vlan_group, the appropriate array is allocated. The check in vlan_group_get_device's is safe, since the pointer vg->vlan_devices_arrays[x] can only switch from NULL to not-NULL. The vlan_group_prealloc_vid() is guarded with rtnl lock and is also safe. I've checked (I hope that) all the places, that use these arrays and found, that the register_vlan_dev is the only place, that can put a vlan device on an empty vlan_group. Rough calculations shows, that after the patch a setup with a single vlan dev (or up to 512 vlans with sequential vids) will occupy approximately 8 times less memory. The question I have is - does this patch makes sense, or a totally new structures are required to store the vlan_devs?

* [NETFILTER]: nf_conntrack_sip: RTP routing optimizationPatrick McHardy2008-03-252-10/+52
| | | | | | | | | | | | | | Optimize call routing between NATed endpoints: when an external registrar sends a media description that contains an existing RTP expectation from a different SNATed connection, the gatekeeper is trying to route the call directly between the two endpoints. We assume both endpoints can reach each other directly and "un-NAT" the addresses, which makes the media stream go between the two endpoints directly.

| | | | | | | | | | | | | | | | address Media streams can come from anywhere, add a module parameter which controls whether wildcard expectations or expectations between the two signalling endpoints are created.

| | | | | | | | | | | | | | SDP and SIP headers are quite different, SIP can have continuation lines, leading and trailing whitespace after the colon and is mostly case-insensitive while SDP headers always begin on a new line and are followed by an equal sign and the value, without any whitespace.

* [NETFILTER]: nf_conntrack: introduce expectation classes and policiesPatrick McHardy2008-03-2512-72/+148
| | | | | | | | | | | | | | | Introduce expectation classes and policies. An expectation class is used to distinguish different types of expectations by the same helper (for example audio/video/t.120). The expectation policy is used to hold the maximum number of expectations and the initial timeout for each class. The individual classes are isolated from each other, which means that for example an audio expectation will only evict other audio expectations.

| | | | | | | | | | | | This is useful for the SIP helper and signalling expectations. We don't want to create a full-blown expectation with a wildcard as source based on a single UDP packet, but need to know the final port anyways. With inactive expectations we can register the expectation and reserve the tuple, but wait for confirmation from the registrar before activating it.
