====================
netlink: access functions for IP address attributes
There are many places that read or write IP addresses to netlink attributes.
With IPv6 addresses, every such place currently has to use generic nla_put
and nla_memcpy. Implementing IPv6 address access functions simplify things
and makes the code more intelligible. IPv4 address access functions has
lesser value but it would be better to be consistent between IPv6 and IPv4
and they still serve as documentation.
The conversion is straightforward and the resulting patches are not that
large, thus I kept all the changes in the patches that introduce the access
functions. If anyone prefers to split the definition of access functions and
the conversion and/or break it out by network protocols, please let me know.
While doing the conversion, I came across ugly typecasting in
inetpeer_addr_base and xfrm_address_t when dealing with IPv6 addresses.

tipc: fix two bugs in secondary destination lookup
A message sent to a node after a successful name table lookup may still
find that the destination socket has disappeared, because distribution
of name table updates is non-atomic. If so, the message will be rejected
back to the sender with error code TIPC_ERR_NO_PORT. If the source
socket of the message has disappeared in the meantime, the message
should be dropped.
However, in the currrent code, the message will instead be subject to an
unwanted tertiary lookup, because the function tipc_msg_lookup_dest()
doesn't check if there is an error code present in the message before
performing the lookup. In the worst case, the message may now find the
old destination again, and be redirected once more, instead of being
dropped directly as it should be.
A second bug in this function is that the "prev_node" field in the message
is not updated after successful lookup, something that may have
unpredictable consequences.
The problems arising from those bugs occur very infrequently.
The third change in this function; the test on msg_reroute_msg_cnt() is
purely cosmetic, reflecting that the returned value never can be negative.

Stacked vlan TSO
On the basis of Netdev 0.1 discussion[1], I made a patch set to enable
TSO for packets with multiple vlans.
Currently, packets with multiple vlans are always segmented by software,
which is caused by that netif_skb_features() drops most feature flags
for multiple tagged packets.
To allow NICs to segment them, we need to get rid of that check from core.
Fortunately, recently introduced ndo_features_check() can be used to
move the check to each driver, and this patch set is based on the idea.
For the initial patch set, I chose 3 drivers, bonding, team, and igb, as
candidates to enable TSO. I tested them and confirmed they works fine
with this change.
Here are samples of performance test results. As I expected, %sys gets
pretty lower than before.
Average: CPU %user %nice %system %iowait %steal %idle

Datasheet says that the Message Port bit should not be set for the CPU port.
Having it set causes DSA tagged packets to be sent to the CPU port roughly

switch ports if the switch is configured for switching between multiple ports.
The packets are then bridged by the software bridge, resulting in duplicated

Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next tree.
Basically, nf_tables updates to add the set extension infrastructure and finish
the transaction for sets from Patrick McHardy. More specifically, they are:
1) Move netns to basechain and use recently added possible_net_t, from
Patrick McHardy.
2) Use LOGLEVEL_<FOO> from nf_log infrastructure, from Joe Perches.
3) Restore nf_log_trace that was accidentally removed during conflict
resolution.
4) nft_queue does not depend on NETFILTER_XTABLES, starting from here
all patches from Patrick McHardy.
5) Use raw_smp_processor_id() in nft_meta.
Then, several patches to prepare ground for the new set extension
infrastructure:
6) Pass object length to the hash callback in rhashtable as needed by
the new set extension infrastructure.
7) Cleanup patch to restore struct nft_hash as wrapper for struct
rhashtable
8) Another small source code readability cleanup for nft_hash.
9) Convert nft_hash to rhashtable callbacks.
And finally...
10) Add the new set extension infrastructure.
11) Convert the nft_hash and nft_rbtree sets to use it.
12) Batch set element release to avoid several RCU grace period in a row
and add new function nft_set_elem_destroy() to consolidate set element
release.
13) Return the set extension data area from nft_lookup.
14) Refactor existing transaction code to add some helper functions
and document it.
15) Complete the set transaction support, using similar approach to what we
already use, to activate/deactivate elements in an atomic fashion.

tipc: involve reference counter for node structure
TIPC node hash node table is protected with rcu lock on read side.
tipc_node_find() is used to look for a node object with node address
through iterating the hash node table. As the entire process of what
tipc_node_find() traverses the table is guarded with rcu read lock,
it's safe for us. However, when callers use the node object returned
by tipc_node_find(), there is no rcu read lock applied. Therefore,
this is absolutely unsafe for callers of tipc_node_find().
Now we introduce a reference counter for node structure. Before
tipc_node_find() returns node object to its caller, it first increases
the reference counter. Accordingly, after its caller used it up,
it decreases the counter again. This can prevent a node being used by
one thread from being freed by another thread.

The correct the sequence of grabbing n_ptr->lock and bclink->lock
should be that the former is first held and the latter is then taken,
which exactly happened on CPU1. But especially when the retransmission
of broadcast link is failed, bclink->lock is first held in
tipc_bclink_rcv(), and n_ptr->lock is taken in link_retransmit_failure()
called by tipc_link_retransmit() subsequently, which is demonstrated on
CPU0. As a result, deadlock occurs.
If the order of holding the two locks happening on CPU0 is reversed, the
deadlock risk will be relieved. Therefore, the node lock taken in
link_retransmit_failure() originally is moved to tipc_bclink_rcv()
so that it's obtained before bclink lock. But the precondition of
the adjustment of node lock is that responding to bclink reset event
must be moved from tipc_bclink_unlock() to tipc_node_unlock().
