net,rcu: convert call_rcu(fc_rport_free_rcu) to kfree_rcu()

2011-05-08T05:50:55+00:00

The rcu callback fc_rport_free_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(fc_rport_free_rcu).

ipv4: Fix nexthop caching wrt. scoping.

2011-03-25T01:06:47+00:00

Move the scope value out of the fib alias entries and into fib_info,
so that we always use the correct scope when recomputing the nexthop
cached source address.

ipv4: Invalidate nexthop cache nh_saddr more correctly.

2011-03-25T00:42:21+00:00

Any operation that:

1) Brings up an interface
2) Adds an IP address to an interface
3) Deletes an IP address from an interface

can potentially invalidate the nh_saddr value, requiring
it to be recomputed.

Perform the recomputation lazily using a generation ID.

ipv4: fix fib metrics

2011-03-24T18:49:54+00:00

Alessandro Suardi reported that we could not change route metrics :

ip ro change default .... advmss 1400

This regression came with commit 9c150e82ac50 (Allocate fib metrics
dynamically). fib_metrics is no longer an array, but a pointer to an
array.

ipv4: Pass ipv4 flow objects into fib_lookup() paths.

2011-03-12T23:08:47+00:00

To start doing these conversions, we need to add some temporary
flow4_* macros which will eventually go away when all the protocol
code paths are changed to work on AF specific flowi objects.

net: Put flowi_* prefix on AF independent members of struct flowi

2011-03-12T23:08:44+00:00

I intend to turn struct flowi into a union of AF specific flowi
structs.  There will be a common structure that each variant includes
first, much like struct sock_common.

This is the first step to move in that direction.

ipv4: Fix scope value used in route src-address caching.

2011-03-08T19:03:21+00:00

We have to use cfg->fc_scope not the final nh_scope value.

ipv4: Cache source address in nexthop entries.

2011-03-08T04:54:48+00:00

When doing output route lookups, we have to select the source address
if the user has not specified an explicit one.

First, if the route has an explicit preferred source address
specified, then we use that.

Otherwise we search the route's outgoing interface for a suitable
address.

This search can be precomputed and cached at route insertion time.

The only missing part is that we have to refresh this precomputed
value any time addresses are added or removed from the interface, and
this is accomplished by fib_update_nh_saddrs().
