2008-03-28drivers/net/arcnet/arcnet.c: use time_* macrosS.Caglar Onur
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So use the time_after() macro, defined in linux/jiffies.h, which deals with wrapping correctly.

2008-03-28[LIB]: Drop the pcounter itself.Pavel Emelyanov
The knock-out. The pcounter abstraction is not used any longer in the kernel. Not sure whether this should go via netdev tree, but as far as I remember it was added via this one, and besides Eric thinks that Andrew shouldn't mind this.

2008-03-28[SOCK]: Introduce a percpu inuse counters array (v2).Pavel Emelyanov
And redirect sock_prot_inuse_add and _get to use one. As far as the dereferences are concerned. Before the patch we made 1 dereference to proto->inuse.add call, the call itself and then called the __get_cpu_var() on a static variable. After the patch we make a direct call, then one dereference to proto->inuse_idx and then the same __get_cpu_var() on a still static variable. So this patch doesn't seem to produce performance penalty on SMP. This is not per-net yet, but I will deliberately make NET_NS=y case separated from NET_NS=n one, since it'll cost us one-or-two more dereferences to get the struct net and the inuse counter.

The inuse counters are going to become a per-cpu array. Introduce an index for this array on the struct proto. To handle the case of proto register-unregister-register loop the bitmap is used.

2008-03-26[IPSEC]: Fix BEET outputHerbert Xu
The IPv6 BEET output function is incorrectly including the inner header in the payload to be protected. This causes a crash as the packet doesn't actually have that many bytes for a second header. The IPv4 BEET output on the other hand is broken when it comes to handling an inner IPv6 header since it always assumes an inner IPv4 header. This patch fixes both by making sure that neither BEET output function touches the inner header at all. All access is now done through the protocol-independent cb structure. Two new attributes are added to make this work, the IP header length and the IPv4 option length. They're filled in by the inner mode's output function.

2008-03-26[VLAN]: Reduce memory consumed by vlan_groupsPavel Emelyanov
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?

2008-03-25[NETFILTER]: nf_conntrack_sip: RTP routing optimizationPatrick McHardy
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.
