netfilter: replace list_head with single linked list

2016-09-25T12:38:48+00:00

The netfilter hook list never uses the prev pointer, and so can be trimmed to
be a simple singly-linked list.

In addition to having a more light weight structure for hook traversal,
struct net becomes 5568 bytes (down from 6400) and struct net_device becomes
2176 bytes (down from 2240).

1) Constify the xfrm_replay structures. From Julia Lawall

2) Protect xfrm state hash tables with rcu, lookups
   can be done now without acquiring xfrm_state_lock.
   From Florian Westphal.

3) Protect xfrm policy hash tables with rcu, lookups
   can be done now without acquiring xfrm_policy_lock.
   From Florian Westphal.

4) We don't need to have a garbage collector list per
   namespace anymore, so use a global one instead.

xfrm: state: remove per-netns gc task

2016-08-24T11:16:06+00:00

After commit 5b8ef3415a21f173
("xfrm: Remove ancient sleeping when the SA is in acquire state")
gc does not need any per-netns data anymore.

As far as gc is concerned all state structs are the same, so we
can use a global work struct for it.

netfilter: remove ip_conntrack* sysctl compat code

2016-08-13T11:27:13+00:00

This backward compatibility has been around for more than ten years,
since Yasuyuki Kozakai introduced IPv6 in conntrack. These days, we have
alternate /proc/net/nf_conntrack* entries, the ctnetlink interface and
the conntrack utility got adopted by many people in the user community
according to what I observed on the netfilter user mailing list.

So let's get rid of this.

Note that nf_conntrack_htable_size and unsigned int nf_conntrack_max do
not need to be exported as symbol anymore.

xfrm: policy: convert policy_lock to spinlock

2016-08-12T06:07:12+00:00

After earlier patches conversions all spots acquire the writer lock and
we can now convert this to a normal spinlock.

xfrm: state: don't use lock anymore unless acquire operation is needed

2016-08-10T09:23:24+00:00

push the lock down, after earlier patches we can rely on rcu to
make sure state struct won't go away.

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Fix incorrect timestamp in nfnetlink_queue introduced when addressing
   y2038 safe timestamp, from Florian Westphal.

2) Get rid of leftover conntrack definition from the previous merge
   window, oneliner from Florian.

3) Make nf_queue handler pernet to resolve race on dereferencing the
   hook state structure with netns removal, from Eric Biederman.

4) Ensure clean exit on unregistered helper ports, from Taehee Yoo.

5) Restore FLOWI_FLAG_KNOWN_NH in nf_dup_ipv6. This got lost while
   generalizing xt_TEE to add packet duplication support in nf_tables,
   from Paolo Abeni.

6) Insufficient netlink NFTA_SET_TABLE attribute check in
   nf_tables_getset(), from Phil Turnbull.

7) Reject helper registration on duplicated ports via modparams.
