====================
10GbE Intel Wired LAN Driver Updates 2018-03-12

This series contains updates to ixgbe and ixgbevf only.

Shannon Nelson provides three fixes to the ipsec portion of ixgbe.  Make
sure we are using 128-bit authentication, since it is the only size
supported for hardware offload.  Fixed the transmit trailer length
calculation for ipsec by finding the padding value and adding it to the
authentication length, then save it off so that we can put it in the
transmit descriptor to tell the device where to stop the checksum
calculation.  Lastly, cleaned up useless and dead code.

Tonghao Zhang adds a ethtool stat for receive length errors, since the
driver was already collecting this counter.

Arnd Bergmann fixed a warning about an used variable by "rephrasing" the
code so that the compiler can see the use of the variable in question.

Paul fixes an issue where "HIDE_VLAN" was being cleared on VF reset, so
ensure to set "HIDE_VLAN" when port VLAN is enabled after a VF reset.

====================
mlxsw: Removing dependency of mlxsw on GRE

Petr says:

mlxsw_spectrum supports offloading of a tc action mirred egress mirror
to a gretap or ip6gretap netdevice, which necessitates calls to
functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously
this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on
NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about
picking which modules are absolutely required, and therefore the better
approach is to make mlxsw_spectrum tolerant of absence of one or both of
the GRE flavors.

One way this might be resolved is by keeping the code in mlxsw_spectrum
intact, and defining defaults for functions that mlxsw_spectrum depends
on. The downsides are that other modules end up littered with these
do-nothing defaults; that the driver ends up carrying quite a bit of
dead code; and that the driver ends up having to explicitly depend on
IPV6_TUNNEL to prevent configurations where mlxsw_spectrum is compiled
in and and ip6_tunnel is a module, something that it currently can treat
as an implementation detail of the IPV6_GRE dependency.

Alternatively, the driver should just bite the bullet and ifdef-out the
code that handles configurations that are not supported. Since that's
what we are doing for IPv6 dependency, let's do the same for the GRE
flavors.

Patch #1 introduces a wrapper function for determining the value of
ipv6.sysctl.multipath_hash_policy, which defaults to 0 on non-IPv6
builds. That function is then used from spectrum_router.c, instead of
the direct variable reference that was introduced there during the short
window when the Spectrum driver had a hard dependency on IPv6.

Patch #2 moves one function to keep together in one block all the
callbacks for handling (IPv4) gretap mirroring.

Patch #3 then introduces the ifdefs to hide the irrelevant code.

 RSS spreading, and the ability to create and configure multiple RSS contexts

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]

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.

ibmvnic: Do not disable device during failover or partition migration

During a device failover or partition migration reset, it is not
necessary to disable the backing adapter since it should not be
running yet and its Command-Response Queue is closed. Sending
device commands during this time could result in an error or
timeout disrupting the reset process. In these cases, just halt
transmissions, clean up resources, and continue with reset.

ibmvnic: Reorganize device close

Introduce a function to halt network operations and clean up any
unused or outstanding socket buffers. Then, during device close,
disable backing adapter before halting all queues and performing
cleanup. This ensures all backing device operations will be
stopped before the driver cleans up shared resources.

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.

6 years agoopenvswitch: fix vport packet length check.

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.

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.

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.
