* net: Embed hh_cache inside of struct neighbour.David S. Miller2011-07-146-81/+48
| | | | | | | | | | | | | | | Now that there is a one-to-one correspondance between neighbour and hh_cache entries, we no longer need: 1) dynamic allocation 2) attachment to dst->hh 3) refcounting Initialization of the hh_cache entry is indicated by hh_len being non-zero, and such initialization is always done with the neighbour's lock held as a writer.

* net: Kill support for multiple hh_cache entries per neighbourDavid S. Miller2011-07-131-19/+18
| | | | | | | | | | | | | This never, ever, happens. Neighbour entries are always tied to one address family, and therefore one set of dst_ops, and therefore one dst_ops->protocol "hh_type" value. This capability was blindly imported by Alexey Kuznetsov when he wrote the neighbour layer. Signed-off-by: David S. Miller <davem@davemloft.net>

* ipv4: Inline neigh binding.David Miller2011-07-132-27/+27
| | | | | | | | | | | | | | | | | Get rid of all of the useless and costly indirection by doing the neigh hash table lookup directly inside of the neighbour binding. Rename from arp_bind_neighbour to rt_bind_neighbour. Use new helpers {__,}ipv4_neigh_lookup() In rt_bind_neighbour() get rid of useless tests which are never true in the context this function is called, namely dev is never NULL and the dst->neighbour is always NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In certain circumstances, like WoWLAN scenarios, devices may implement (partial) GTK rekeying on the device to avoid waking up the host for it. In order to successfully go through GTK rekeying, the KEK, KCK and the replay counter are required. Add API to let the supplicant hand the parameters to the driver which may store it for future GTK rekey operations. Note that, of course, if GTK rekeying is done by the device, the EAP frame must not be passed up to userspace, instead a rekey event needs to be sent to let userspace update its replay counter.

A new struct skb_ubuf_info is needed to maintain the userspace buffers argument and index, a callback is used to notify userspace to release the buffers once lower device has done DMA (Last reference to that skb has gone). If there is any userspace apps to reference these userspace buffers, then these userspaces buffers will be copied into kernel. This way we can prevent userspace apps from holding these userspace buffers too long. Use destructor_arg to point to the userspace buffer info; a new tx flags SKBTX_DEV_ZEROCOPY is added for zero-copy buffer check. Signed-off-by: Shirley Ma <xma@...ibm.com> Signed-off-by: David S.

This is useful when the user-mode DCB client is not responsible for conducting and resolving the DCBX negotiation (either because the DCBX stack is embedded in the HW or the negotiation is handled by another agent in the host), but still needs to get the negotiated parameters. This functionality already exists for the IEEE flavor of the DCBX protocol and these patches add it to the older CEE flavor. The first patch extends the CEE attribute GET operation to include not only the peer information, but also all the pertinent local configuration (negotiated parameters). The second patch adds and export a CEE specific notification routine. Signed-off-by: Shmulik Ravid <shmulikr@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * | | ipv6: Don't put artificial limit on routing table size.David S. Miller2011-07-012-8/+11

Routing table entries, as well as clones made in response to route lookup requests, all live in the same table. And all of these things are together collected in the destination cache table for ipv6. This means that routing table entries count against the garbage collection limits, even though such entries cannot ever be reclaimed and are added explicitly by the administrator (rather than being created in response to lookups). Therefore it makes no sense to count ipv6 routing table entries against the GC limits. Add a DST_NOCOUNT destination cache entry flag, and skip the counting if it is set. Use this flag bit in ipv6 when adding routing table entries. Signed-off-by: David S. Miller <davem@davemloft.net>
