[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.

[IPV4]: fib_rules_unregister is essentially void.

2008-01-28T23:02:09+00:00

fib_rules_unregister is called only after successful register and the
return code is never checked.

[NETNS]: Namespacing in the generic fib rules code.

2008-01-28T23:01:23+00:00

Move static rules_ops & rules_mod_lock to the struct net, register the
pernet subsys to init them and enjoy the fact that the core rules
infrastructure works in the namespace.

Real IPv4 fib rules virtualization requires fib tables support in the
namespace and will be done seriously later in the patchset.

[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.

[NETNS]: Add netns parameter to fib_rules_(un)register.

2008-01-28T23:01:21+00:00

The patch extends the different fib rules API in order to pass the
network namespace pointer. That will allow to access the different
tables from a namespace relative object. As usual, the pointer to the
init_net variable is passed as parameter so we don't break the
network.

[IPV6]: Make fib6_rules_init to return an error code.

2008-01-28T22:56:46+00:00

When the fib_rules initialization finished, no return code is provided
so there is no way to know, for the caller, if the initialization has
been successful or has failed. This patch fix that.

[NET]: Make rtnetlink infrastructure network namespace aware (v3)

2008-01-28T22:54:25+00:00

After this patch none of the netlink callback support anything
except the initial network namespace but the rtnetlink infrastructure
now handles multiple network namespaces.

Changes from v2:
- IPv6 addrlabel processing

Changes from v1:
- no need for special rtnl_unlock handling
- fixed IPv6 ndisc

[NET]: Modify all rtnetlink methods to only work in the initial namespace (v2)

2008-01-28T22:54:24+00:00

Before I can enable rtnetlink to work in all network namespaces I need
to be certain that something won't break.  So this patch deliberately
disables all of the rtnletlink methods in everything except the
initial network namespace.  After the methods have been audited this
extra check can be disabled.

Changes from v1:
- added IPv6 addrlabel protection

[INET]: Small possible memory leak in FIB rules

2007-11-11T06:12:03+00:00

This patch fixes a small memory leak. Default fib rules can be deleted by
the user if the rule does not carry FIB_RULE_PERMANENT flag, f.e. by
	ip rule flush

Such a rule will not be freed as the ref-counter has 2 on start and becomes
clearly unreachable after removal.
