ipv6: ip6_route_output() never returns NULL.

2012-02-22T20:30:14+00:00

ip6_route_output() never returns NULL, so it is wrong to
check if the return value is NULL.

ipv6: Check RA for sllao when configuring optimistic ipv6 address (v2)

2012-01-04T20:53:20+00:00

Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop
route for the interface we're adding an addres to was wrong (see commit
7ffbcecbeed91e5874e9a1cfc4c0cbb07dac3069).  for one, it never triggers, and two,
it was completely wrong to begin with.  This test was meant to cover this
section of RFC 4429:

3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration

   * (modifies section 5.5) A host MAY choose to configure a new address
        as an Optimistic Address.  A host that does not know the SLLAO
        of its router SHOULD NOT configure a new address as Optimistic.
        A router SHOULD NOT configure an Optimistic Address.

This patch should bring us into proper compliance with the above clause.  Since
we only add a SLAAC address after we've received a RA which may or may not
contain a source link layer address option, we can pass a pointer to that option
to addrconf_prefix_rcv (which may be null if the option is not present), and
only set the optimistic flag if the option was found in the RA.

Change notes:
(v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than
a pointer to make its use more clear as per request from davem.

ipv6: Kill rt6i_dev and rt6i_expires defines.

2011-12-29T01:19:20+00:00

It just obscures that the netdevice pointer and the expires value are
implemented in the dst_entry sub-object of the ipv6 route.

And it makes grepping for dst_entry member uses much harder too.

ipv6: Use universal hash for NDISC.

2011-12-28T20:06:58+00:00

In order to perform a proper universal hash on a vector of integers,
we have to use different universal hashes on each vector element.

Which means we need 4 different hash randoms for ipv6.

neigh: Do not set tbl->entry_size in ipv4/ipv6 neigh tables.

Let the core self-size the neigh entry based upon the key length.
