[NETNS][IPV6] rt6_info - move rt6_info structure inside the namespace

2008-03-04T21:48:30+00:00

The rt6_info structures are moved inside the network namespace
structure. All references to these structures are now relative to the
initial network namespace.

[NETNS][IPV6] ip6_fib - add net to gc timer parameter

2008-03-04T07:28:58+00:00

The fib tables are now relative to the network namespace. When the
garbage collector timer expires, we must have a network namespace
parameter in order to retrieve the tables. For now this is the
init_net, but we should be able to have a timer per namespace and use
the timer callback parameter to pass the network namespace from the
expired timer.

The timer callback, fib6_run_gc, is actually used to be called
synchronously by some functions and asynchronously when the timer
expires.

When the timer expires, the delay specified for fib6_run_gc parameter
is always zero. So, I changed fib6_run_gc to not be a timer callback
but a function called by the timer callback and I added a timer
callback where its work is just to retrieve from the data arg of the
timer the network namespace and call fib6_run_gc with zero expiring
time and the network namespace parameters. That makes the code cleaner
for the fib6_run_gc callers.

[NETNS][IPV6] ip6_fib - fib6_clean_all handle several network namespaces

2008-03-04T07:27:06+00:00

The function fib6_clean_all takes the network namespace as
parameter. That allows to flush the routes related to a specific
network namespace.

[NETNS][IPV6] ip6_fib - make it per network namespace

2008-03-04T07:25:27+00:00

The fib table for ipv6 are moved to the network namespace structure.
All references to them are made relatively to the network namespace.

All external calls to the ip6_fib functions taking the network
namespace parameter are made using the init_net variable, so the
ip6_fib engine is ready for the namespaces but the callers not yet.

[IPV6] Minor cleanup: remove unused definitions in net/ip6_fib.h

2008-02-08T02:11:49+00:00

This patch removes some unused definitions and one method typedef
declaration (f_pnode)
in include/net/ip6_fib.h, as they are not used in the kernel.

[XFRM] IPv6: Fix dst/routing check at transformation.

2008-01-28T22:59:36+00:00

IPv6 specific thing is wrongly removed from transformation at net-2.6.25.
This patch recovers it with current design.

o Update "path" of xfrm_dst since IPv6 transformation should
  care about routing changes. It is required by MIPv6 and
  off-link destined IPsec.
o Rename nfheader_len which is for non-fragment transformation used by
  MIPv6 to rt6i_nfheader_len as IPv6 name space.

[IPV6]: route6 remove ifdef for fib_rules

2008-01-28T22:56:59+00:00

The patch defines the usual static inline functions when the code is
disabled for fib6_rules. That's allow to remove some ifdef in route.c
file and make the code a little more clear.

[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.

[IPV6]: Make fib6_init to return an error code.

2008-01-28T22:56:45+00:00

If there is an error in the initialization function, nothing is
followed up to the caller. So I add a return value to be set for the
init function.

[IPV6]: Move nfheader_len into rt6_info

2008-01-28T22:53:37+00:00

The dst member nfheader_len is only used by IPv6.  It's also currently
creating a rather ugly alignment hole in struct dst.  Therefore this patch
moves it from there into struct rt6_info.

It also reorders the fields in rt6_info to minimize holes.
