3b8bc67413 net: mvneta: ensure PM paths take the rtnl lock
The netdev core always ensures that the rtnl lock is held while calling
the ndo_open() and ndo_stop() methods. However, the suspend/resume paths
do not hold the rtnl lock. phylink will expect the rtnl lock to be held
when the MAC driver calls it, so we end up with kernel warnings. Take
the lock to ensure that these functions are called in a consistent
manner.

4282fc47c0 sh_eth: kill redundant check in the probe() method
Browsing thru the driver disassembly, I noticed that gcc was  able to
figure  out  that the 'ndev' pointer is always non-NULL when calling
free_netdev()  on the probe() method's  error path and  thus skip that
redundant NULL check... gcc is smart, be like gcc! :-)

475c5ee193 Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU updates from Paul E. McKenney:

- Updates to use cond_resched() instead of cond_resched_rcu_qs()
  where feasible (currently everywhere except in kernel/rcu and
  in kernel/torture.c).  Also a couple of fixes to avoid sending
  IPIs to offline CPUs.

- Updates to simplify RCU's dyntick-idle handling.

- Updates to remove almost all uses of smp_read_barrier_depends()
  and read_barrier_depends().

- Miscellaneous fixes.

- Torture-test updates.

- Whitespace changes to align values and code blocks.
- Comments are updated (spelling mistakes, removed if not clear).
- Group together code blocks which are related or deal with similar
 matters.

IPv6 for LIP is not supported. So, for IPv6 TCAM filters on T6,
add LIP6 to CLIP on filter creation, and release the same on filter

d02fd6e7d2 macvlan: Fix one possible double free
Because the macvlan_uninit would free the macvlan port, so there is one
double free case in macvlan_common_newlink. When the macvlan port is just
created, then register_netdevice or netdev_upper_dev_link failed and they
would invoke macvlan_uninit. Then it would reach the macvlan_port_destroy
which triggers the double free.

90045fc9c7 mlxsw: spectrum: Relax sanity checks during enslavement
Since commit 25cc72a338 ("mlxsw: spectrum: Forbid linking to devices that
have uppers") the driver forbids enslavement to netdevs that already
have uppers of their own, as this can result in various ordering
problems.

This requirement proved to be too strict for some users who need to be
able to enslave ports to a bridge that already has uppers. In this case,
we can allow the enslavement if the bridge is already known to us, as
any configuration performed on top of the bridge was already reflected
to the device.

When we remove the neighbour associated with a nexthop we should always
refuse to write the nexthop to the adjacency table. Regardless if it is
already present in the table or not.

Otherwise, we risk dereferencing the NULL pointer that was set instead
of the neighbour.

52a589d51f geneve: update skb dst pmtu on tx path
Commit a93bf0ff44 ("vxlan: update skb dst pmtu on tx path") has fixed
a performance issue caused by the change of lower dev's mtu for vxlan.

The same thing needs to be done for geneve as well.

Note that geneve cannot adjust it's mtu according to lower dev's mtu
when creating it. The performance is very low later when netperfing
over it without fixing the mtu manually. This patch could also avoid
this issue.

cae1927c0b bpf: offload: allow netdev to disappear while verifier is running
To allow verifier instruction callbacks without any extra locking
NETDEV_UNREGISTER notification would wait on a waitqueue for verifier
to finish.  This design decision was made when rtnl lock was providing
all the locking.  Use the read/write lock instead and remove the
workqueue.

Verifier will now call into the offload code, so dev_ops are moved
to offload structure.  Since verifier calls are all under
bpf_prog_is_dev_bound() we no longer need static inline implementations
to please builds with CONFIG_NET=n.
