[IPV4]: Consolidate fib_select_default.

2008-01-28T23:11:02+00:00

The difference in the implementation of the fib_select_default when
CONFIG_IP_MULTIPLE_TABLES is (not) defined looks
negligible. Consolidate it and place into fib_frontend.c.

[NETNS]: Process FIB rule action in the context of the namespace.

2008-01-28T23:08:14+00:00

Save namespace context on the fib rule at the rule creation time and
call routing lookup in the correct namespace.

[NETNS]: FIB rules API cleanup.

2008-01-28T23:08:13+00:00

Remove struct net from fib_rules_register(unregister)/notify_change
paths and diet code size a bit.

[FIB]: Add netns to fib_rules_ops.

2008-01-28T23:08:13+00:00

The backward link from FIB rules operations to the network namespace
will allow to simplify the API a bit.

[NETNS]: Namespacing IPv4 fib rules.

2008-01-28T23:01:31+00:00

The final trick for rules: place fib4_rules_ops into struct net and
modify initialization path for this.

[NETNS]: Add netns parameter to fib_get_table/fib_new_table.

2008-01-28T23:01:27+00:00

This patch extends the fib_get_table and the fib_new_table functions
with the network namespace pointer. That will allow to access the
table relatively from the network namespace.

[NETNS]: Refactor fib initialization so it can handle multiple namespaces.

2008-01-28T23:01:25+00:00

This patch makes the fib to be initialized as a subsystem for the
network namespaces. The code does not handle several namespaces yet,
so in case of a creation of a network namespace, the
creation/initialization will not occur.

[IPV4]: Check fib4_rules_init failure.

2008-01-28T23:01:25+00:00

This adds error paths into both versions of fib4_rules_init
(with/without CONFIG_IP_MULTIPLE_TABLES) and returns error code to the
caller.

[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.
