inetpeer: Use correct AVL tree base pointer in inet_getpeer().

2011-01-24T22:38:09+00:00

Family was hard-coded to AF_INET but should be daddr->family.

This fixes crashes when unlinking ipv6 peer entries, since the
unlink code was looking up the base pointer properly.

inetpeer: Kill use of inet_peer_address_t typedef.

2010-12-02T01:28:18+00:00

They are verboten these days.

ipv6: Add infrastructure to bind inet_peer objects to routes.

2010-11-30T20:27:11+00:00

They are only allowed on cached ipv6 routes.

inetpeer: Add v6 peers tree, abstract root properly.

2010-11-30T20:12:23+00:00

Add the ipv6 peer tree instance, and adapt remaining
direct references to 'v4_peers' as needed.

inetpeer: Abstract address comparisons.

2010-11-30T20:08:53+00:00

Now v4 and v6 addresses will both work properly.

inetpeer: Make inet_getpeer() take an inet_peer_adress_t pointer.

2010-11-30T19:54:19+00:00

And make an inet_getpeer_v4() helper, update callers.

inetpeer: Introduce inet_peer_address_t.

2010-11-30T19:53:55+00:00

Currently only the v4 aspect is used, but this will change.

inetpeer: Abstract out the tree root accesses.

2010-11-30T19:41:59+00:00

Instead of directly accessing "peer", change to code to
operate using a "struct inet_peer_base *" pointer.

This will facilitate the addition of a seperate tree for
ipv6 peer entries.

inetpeer: __rcu annotations

2010-10-27T18:37:33+00:00

Adds __rcu annotations to inetpeer
	(struct inet_peer)->avl_left
	(struct inet_peer)->avl_right

This is a tedious cleanup, but removes one smp_wmb() from link_to_pool()
since we now use more self documenting rcu_assign_pointer().

Note the use of RCU_INIT_POINTER() instead of rcu_assign_pointer() in
all cases we dont need a memory barrier.

inetpeer: restore small inet_peer structures

2010-06-16T18:55:39+00:00

Addition of rcu_head to struct inet_peer added 16bytes on 64bit arches.

Thats a bit unfortunate, since old size was exactly 64 bytes.

This can be solved, using an union between this rcu_head an four fields,
that are normally used only when a refcount is taken on inet_peer.
rcu_head is used only when refcnt=-1, right before structure freeing.

Add a inet_peer_refcheck() function to check this assertion for a while.

We can bring back SLAB_HWCACHE_ALIGN qualifier in kmem cache creation.
