ipv4: Fix fib_info->fib_metrics leak

2011-09-16T21:42:26+00:00

Commit 4670994d(net,rcu: convert call_rcu(fc_rport_free_rcu) to
kfree_rcu()) introduced a memory leak. This patch reverts it.

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.

Completely unused.

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.
