* [VLAN]: Reduce memory consumed by vlan_groupsPavel Emelyanov2008-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 McHardy2008-03-25
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | The SDP connection addresses may be contained in the payload multiple times (in the session description and/or once per media description), currently only the session description is properly updated. Split up SDP mangling so the function setting up expectations only updates the media port, update connection addresses from media descriptions while parsing them and at the end update the session description when the final addresses are known.

* [NETFILTER]: nf_conntrack: introduce expectation classes and policiesPatrick McHardy2008-03-25
| | | | | | | | | | | | | | | 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.
