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. ==================== Signed-off-by: NDavid S.

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.

Merge tag 'mlx5-updates-2018-02-28-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Saeed Mahameed says: ==================== 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.

Thomas Falcon says: ==================== ibmvnic: Clean up net close and fix reset bug This patch set cleans up and reorganizes the driver's net_device close function and leverages that to fix up a bug that can occur during some device resets. Some reset cases require the backing adapter to be disabled before continuing, but other cases, such as during a device failover or partition migration, do not require this step. Since the device will not be initialized at this stage and its command-processing queue is closed, do not send the request to disable the device as it could result in an error or timeout disrupting the reset. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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.

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. Signed-off-by: NThomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: NDavid S.

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.

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.

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.
