net: reintroduce missing rcu_assign_pointer() calls

2012-02-03T17:22:20+00:00

[ Upstream commit cf778b00e96df6d64f8e21b8395d1f8a859ecdc7 ]

commit a9b3cd7f32 (rcu: convert uses of rcu_assign_pointer(x, NULL) to
RCU_INIT_POINTER) did a lot of incorrect changes, since it did a
complete conversion of rcu_assign_pointer(x, y) to RCU_INIT_POINTER(x,
y).

We miss needed barriers, even on x86, when y is not NULL.

net: Add a flow_cache_flush_deferred function

2011-12-21T21:48:08+00:00

flow_cach_flush() might sleep but can be called from
atomic context via the xfrm garbage collector. So add
a flow_cache_flush_deferred() function and use this if
the xfrm garbage colector is invoked from within the
packet path.

net: Move mtu handling down to the protocol depended handlers

2011-11-26T19:29:51+00:00

We move all mtu handling from dst_mtu() down to the protocol
layer. So each protocol can implement the mtu handling in
a different manner.

net: Rename the dst_opt default_mtu method to mtu

2011-11-26T19:29:50+00:00

We plan to invoke the dst_opt->default_mtu() method unconditioally
from dst_mtu(). So rename the method to dst_opt->mtu() to match
the name with the new meaning.

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

net: add skb frag size accessors

2011-10-19T07:10:46+00:00

To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.

Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.

duplications. This patch removes the duplications.
