Guenter Roeck 366f0a0f98 net: dsa: mv88e6xxx: Disable Message Port bit for CPU port
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
every 30 seconds. Those packets are the same as real packets forwarded between
switch ports if the switch is configured for switching between multiple ports.
The packets are then bridged by the software bridge, resulting in duplicated
packets on the network.

Pablo Neira Ayuso says:

====================
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.

Ying Xue 8a0f6ebe84 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().

====================
be2net: patch set

Hi David, this patch set includes 2 feature additions to the be2net driver:

Patch 1 sets up cpu affinity hints for be2net irqs using the
cpumask_set_cpu_local_first() API that first picks the near numa cores
and when they are exhausted, selects the far numa cores.

Patch 2 setups up xps queue mapping for be2net's TXQs to avoid,
by default, TX lock contention.

Patch 3 just bumps up the driver version.

Pls consider applying this patch set to the net-next queue. Thanks!

Sathya Perla 73f394e629 be2net: setup xps queue mapping
This patch sets up xps queue mapping on load, so that TX traffic is
steered to the queue whose irqs are being processed by the current cpu.
This helps in avoiding TX lock contention.

Padmanabh Ratnakar d658d98aa5 be2net: assign CPU affinity hints to be2net IRQs
This patch provides hints to irqbalance to map be2net IRQs to
specific CPU cores. cpumask_set_cpu_local_first() is used, which first
maps IRQs to near NUMA cores; when those cores are exhausted, IRQs are
mapped to far NUMA cores.

After commit 1fb6f159fd ("tcp: add tcp_conn_request"),
tcp_syn_flood_action() is no longer used from IPv6.

We can make it static, by moving it above tcp_conn_request()

Alexander Aring 3ff7092bc8 at86rf230: remove unnecessary spinlock
This spinlock isn't necessary because if we are in TX_ON/TX_ARET_ON
state the transceiver can't be interrupted e.g. by receiving a frame
when a SHR was detected. In this time the transceiver doesn't leave
the TX_ON/TX_ARET_ON state until the tx complete irq change the state
into RX_AACK_ON again. This means a receiving interrupt in state
TX_ON/TX_ARET_ON can't happen and is_tx is protected by transceiver.

Call the netdev carrier off and TX disable functions first, before other
shutdown operations. This stops the stack from hitting us with
transmits while we're shutting down. Additionally, disable NAPI before
disabling interrupts, or the interrupt might get re-enabled
inappropriately. Finally, remove the call to netif_tx_stop_all_queues,
as it is redundant - the call to netif_tx_disable already did the same
thing.
