f5426250a6 net: introduce IFF_NO_RX_HANDLER
Some network devices - notably ipvlan slave - are not compatible with
any kind of rx_handler. Currently the hook can be installed but any
configuration (bridge, bond, macsec, ...) is nonfunctional.

This change allocates a priv_flag bit to mark such devices and explicitly
forbid installing a rx_handler if such bit is set. The new bit is used
by ipvlan slave device.

0623951eb8 Merge branch 'sched-action-events'
Roman Mashak says:

====================
Fix event generation for actions batch Add/Delete mode

When adding or deleting a batch of entries, the kernel sends upto
TCA_ACT_MAX_PRIO entries in an event to user space. However it does not
consider that the action sizes may vary and require different skb sizes.

For example :

% cat tc-batch.sh
TC="sudo /mnt/iproute2.git/tc/tc"

$TC actions flush action gact
for i in `seq 1 $1`;
do
   cmd="action pass index $i "
   args=$args$cmd
done
$TC actions add $args
%
% ./tc-batch.sh 32
Error: Failed to fill netlink attributes while adding TC action.
We have an error talking to the kernel
%

This patchset introduces new callback in tc_action_ops, which calculates
the action size, and passes size to tcf_add_notify()/tcf_del_notify(). The
patch fixes act_gact, and the rest of actions will be updated in the
follow-up patches.

v3:
   Fixed tcf_action_fill_size() to return shared attrs length when
   action ->get_fill_size() isn't implemented.
v2:
   Restructured patches to make them bisectable.

79134e6ce2 net: do not create fallback tunnels for non-default namespaces
fallback tunnels (like tunl0, gre0, gretap0, erspan0, sit0,
ip6tnl0, ip6gre0) are automatically created when the corresponding
module is loaded.

These tunnels are also automatically created when a new network
namespace is created, at a great cost.

In many cases, netns are used for isolation purposes, and these
extra network devices are a waste of resources. We are using
thousands of netns per host, and hit the netns creation/delete
bottleneck a lot. (Many thanks to Kirill for recent work on this)

Add a new sysctl so that we can opt-out from this automatic creation.

Note that these tunnels are still created for the initial namespace,
to be the least intrusive for typical setups.

Tested:
lpk43:~# cat add_del_unshare.sh
for i in `seq 1 40`
do
 (for j in `seq 1 100` ; do  unshare -n /bin/true >/dev/null ; done) &

9b5d5f4f96 Merge branch 'ntuple-filters-with-RSS'
Edward Cree says:

====================
ntuple filters with RSS

This series introduces the ability to mark an ethtool steering filter to use
 RSS spreading, and the ability to create and configure multiple RSS contexts
 with different indirection tables, hash keys, and hash fields.
An implementation for the sfc driver (for 7000-series and later SFC NICs) is
 included in patch 2/2.

The anticipated use case of this feature is for steering traffic destined for
 a container (or virtual machine) to the subset of CPUs on which processes in
 the container (or the VM's vCPUs) are bound, while retaining the scalability
 of RSS spreading from the viewpoint inside the container.
The use of both a base queue number (ring_cookie) and indirection table is
 intended to allow re-use of a single RSS context to target multiple sets of
 CPUs.  For instance, if an 8-core system is hosting three containers on CPUs
 [1,2], [3,4] and [6,7], then a single RSS context with an equal-weight [0,1]
 indirection table could be used to target all three containers by setting
 ring_cookie to 1, 3 and 6 on the respective filters.

v2: Initialised ctx in efx_ef10_filter_insert() to avoid (false positive) gcc
 warning.

We use a two-step process to configure a filter with RSS spreading.  First,
 the RSS context is allocated and configured using ETHTOOL_SRSSH; this
 returns an identifier (rss_context) which can then be passed to subsequent
 invocations of ETHTOOL_SRXCLSRLINS to specify that the offset from the RSS
 indirection table lookup should be added to the queue number (ring_cookie)
 when delivering the packet.  Drivers for devices which can only use the
 indirection table entry directly (not add it to a base queue number)
 should reject rule insertions combining RSS with a nonzero ring_cookie.

fd372a7a9e mlx5-updates-2018-02-28-2 (IPSec-2)
This series follows our previous one to lay out the foundations for IPSec
 in user-space and extend current kernel netdev IPSec support. As noted in
 our previous pull request cover letter "mlx5-updates-2018-02-28-1 (IPSec-1)",
 the IPSec mechanism will be supported through our flow steering mechanism.
 Therefore, we need to change the initialization order. Furthermore, IPsec
 is also supported in both egress and ingress. Since our current flow
 steering is egress only, we add an empty (only implemented through FPGA
 steering ops) egress namespace to handle that case. We also implement
 the required flow steering callbacks and logic in our FPGA driver.
 
 We extend the FPGA support for ESN and modifying a xfrm too. Therefore, we
 add support for some new FPGA command interface that supports them. The
 other required bits are added too. The new features and requirements are
 advertised via cap bits.
 
 Last but not least, we revise our driver's accel_esp API. This API will be
 shared between our netdev and IB driver, so we need to have all the required
 functionality from both worlds.

f873866a05 ibmvnic: Clean up device close
Remove some dead code now that RX pools are being cleaned. This
was included to wait until any pending RX queue interrupts are
processed, but NAPI polling should be disabled by this point.

Another minor change is to use the net device parameter for any
print functions instead of accessing it from the adapter structure.

46e371f0e7 openvswitch: fix vport packet length check.
When sending a packet to a tunnel device, the dev's hard_header_len
could be larger than the skb->len in function packet_length().
In the case of ip6gretap/erspan, hard_header_len = LL_MAX_HEADER + t_hlen,
which is around 180, and an ARP packet sent to this tunnel has
skb->len = 42.  This causes the 'unsign int length' to become super
large because it is negative value, causing the later ovs_vport_send
to drop it due to over-mtu size.  The patch fixes it by setting it to 0.

Kirill Tkhai says:

====================
Converting pernet_operations (part #5)

this series continues to review and to convert pernet_operations
to make them possible to be executed in parallel for several
net namespaces in the same time. There are mostly netfilter
operations (and they should be the last netfilter's), also
there are two patches touching pktgen and xfrm.

1fd2c55705 net: Convet ipv6_net_ops
These pernet_operations are similar to ipv4_net_ops.
They are safe to be async.

e8a95ad463 net: Convert ipv4_net_ops
These pernet_operations register and unregister bunch
of nf_conntrack_l4proto. Exit method unregisters related
sysctl, init method calls init_net and get_net_proto.
The whole builtin_l4proto4 array has pretty simple
init_net and get_net_proto methods. The first one register
sysctl table, the second one is just RO memory dereference.
So, these pernet_operations are safe to be marked as async.

59d269731e net: Convert pg_net_ops
These pernet_operations create per-net pktgen threads
and /proc entries. These pernet subsys looks closed
in itself, and there are no pernet_operations outside
this file, which are interested in the threads.
Init and/or exit methods look safe to be executed
in parallel.
