ip: Use inline function dst_metric() instead of direct access to dst->metric[]

2008-05-05T05:14:42+00:00

There are functions to refer to the value of dst->metric[THE_METRIC-1]
directly without use of a inline function "dst_metric" defined in
net/dst.h.

The following patch changes them to use the inline function
consistently.

[NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS.

2008-03-25T19:39:55+00:00

Introduce per-sock inlines: sock_net(), sock_net_set()
and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set().
Without CONFIG_NET_NS, no namespace other than &init_net exists.
Let's explicitly define them to help compiler optimizations.

[ATALK/DECNET]: Use seq_open_private in appletalk and decnet.

2008-02-29T19:38:24+00:00

These two also perform manual seq_open_private, so patch them both at
once. But unlike ATM code, these already use the seq_release_private,
so I splitted this patch from the previous one.

[DECNET] ROUTE: remove unecessary alignment

2008-02-08T07:29:57+00:00

Same alignment requirement was removed on IP route cache in the past.

This alignment actually has bad effect on 32 bit arches, uniprocessor,
since sizeof(dn_rt_hash_bucket) is forced to 8 bytes instead of 4.

[NETNS][DST] dst: pass the dst_ops as parameter to the gc functions

2008-01-28T23:02:46+00:00

The garbage collection function receive the dst_ops structure as
parameter. This is useful for the next incoming patchset because it
will need the dst_ops (there will be several instances) and the
network namespace pointer (contained in the dst_ops).

The protocols which do not take care of the namespaces will not be
impacted by this change (expect for the function signature), they do
just ignore the parameter.

[NETNS]: Pass fib_rules_ops into default_pref method.

2008-01-28T23:01:22+00:00

fib_rules_ops contains operations and the list of configured rules. ops will
become per/namespace soon, so we need them to be known in the default_pref
callback.
