Conflicts: net/bluetooth/l2cap_core.c Just two overlapping changes, one added an initialization of a local variable, and another change added a new local variable. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-12-21net: Add a flow_cache_flush_deferred functionSteffen Klassert
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.

2011-11-26net: Move mtu handling down to the protocol depended handlersSteffen Klassert
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. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-26net: Rename the dst_opt default_mtu method to mtuSteffen Klassert
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. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-22xfrm: optimize ipv4 selector matchingAlexey Dobriyan
Current addr_match() is errh, under-optimized. Compiler doesn't know that memcmp() branch doesn't trigger for IPv4. Also, pass addresses by value -- they fit into register. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-07-18net: Add ->neigh_lookup() operation to dst_opsDavid S. Miller
In the future dst entries will be neigh-less. In that environment we need to have an easy transition point for current users of dst->neighbour outside of the packet output fast path. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-05-10xfrm: Assign the inner mode output function to the dst entrySteffen Klassert
As it is, we assign the outer modes output function to the dst entry when we create the xfrm bundle. This leads to two problems on interfamily scenarios. We might insert ipv4 packets into ip6_fragment when called from xfrm6_output. The system crashes if we try to fragment an ipv4 packet with ip6_fragment. This issue was introduced with git commit ad0081e4 (ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed). The second issue is, that we might insert ipv4 packets in netfilter6 and vice versa on interfamily scenarios. With this patch we assign the inner mode output function to the dst entry when we create the xfrm bundle. So xfrm4_output/xfrm6_output from the inner mode is used and the right fragmentation and netfilter functions are called. We switch then to outer mode with the output_finish functions.

2011-04-28net: Use non-zero allocations in dst_alloc().David S. Miller
Make dst_alloc() and it's users explicitly initialize the entire entry. The zero'ing done by kmem_cache_zalloc() was almost entirely redundant. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-04-28net: Make dst_alloc() take more explicit initializations.David S. Miller
Now the dst->dev, dev->obsolete, and dst->flags values can be specified as well. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-16xfrm: Refcount destination entry on xfrm_lookupSteffen Klassert
We return a destination entry without refcount if a socket policy is found in xfrm_lookup. This triggers a warning on a negative refcount when freeeing this dst entry. So take a refcount in this case to fix it. This refcount was forgotten when xfrm changed to cache bundles instead of policies for outgoing flows.

2011-03-12net: Break struct flowi out into AF specific instances.David S. Miller
Now we have struct flowi4, flowi6, and flowidn for each address family. And struct flowi is just a union of them all. It might have been troublesome to convert flow_cache_uli_match() but as it turns out this function is completely unused and therefore can be simply removed. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Make flowi ports AF dependent.David S. Miller
Create two sets of port member accessors, one set prefixed by fl4_* and the other prefixed by fl6_* This will let us to create AF optimal flow instances. It will work because every context in which we access the ports, we have to be fully aware of which AF the flowi is anyways. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Put flowi_* prefix on AF independent members of struct flowiDavid S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>
