vsock: handle buffer_size sockopts in the core

virtio_transport and vmci_transport handle the buffer_size
sockopts in a very similar way.

In order to support multiple transports, this patch moves this
handling in the core to allow the user to change the options
also if the socket is not yet assigned to any transport.

This patch also adds the '.notify_buffer_size' callback in the
'struct virtio_transport' in order to inform the transport,
when the buffer_size is changed by the user. It is also useful
to limit the 'buffer_size' requested (e.g. virtio transports).

net: openvswitch: add hash info to upcall

When using the kernel datapath, the upcall don't
include skb hash info relatived. That will introduce
some problem, because the hash of skb is important
in kernel stack. For example, VXLAN module uses
it to select UDP src port. The tx queue selection
may also use the hash in stack.

Hash is computed in different ways. Hash is random
for a TCP socket, and hash may be computed in hardware,
or software stack. Recalculation hash is not easy.

Hash of TCP socket is computed:
tcp_v4_connect
    -> sk_set_txhash (is random)

__tcp_transmit_skb
    -> skb_set_hash_from_sk

There will be one upcall, without information of skb
hash, to ovs-vswitchd, for the first packet of a TCP
session. The rest packets will be processed in Open vSwitch
modules, hash kept. If this tcp session is forward to
VXLAN module, then the UDP src port of first tcp packet
is different from rest packets.

TCP packets may come from the host or dockers, to Open vSwitch.
To fix it, we store the hash info to upcall, and restore hash
when packets sent back.

PTP clock source for SJA1105 tc-taprio offload

This series makes the IEEE 802.1Qbv egress scheduler of the sja1105
switch use a time reference that is synchronized to the network. This
enables quite a few real Time Sensitive Networking use cases, since in
this mode the switch can offer its clients a TDMA sort of access to the
network, and guaranteed latency for frames that are properly scheduled
based on the common PTP time.

The driver needs to do a 2-part activity:
- Program the gate control list into the static config and upload it
  over SPI to the switch (already supported)
- Write the activation time of the scheduler (base-time) into the
  PTPSCHTM register, and set the PTPSTRTSCH bit.
- Monitor the activation of the scheduler at the planned time and its
  health.

Ok, 3 parts.

The time-aware scheduler cannot be programmed to activate at a time in
the past, and there is some logic to avoid that.

4 years agonet/mlx5: Read num_vfs before disabling SR-IOV
Parav Pandit [Mon, 28 Oct 2019 18:29:17 +0000 (13:29 -0500)]
net/mlx5: Read num_vfs before disabling SR-IOV

mlx5_device_disable_sriov() currently reads num_vfs from the PCI core.
However when mlx5_device_disable_sriov() is executed, SR-IOV is
already disabled at the PCI level.
Due to this disable_hca() cleanup is not done during SR-IOV disable
flow.

mlx5_sriov_disable()
  pci_enable_sriov()
  mlx5_device_disable_sriov() <- num_vfs is zero here.

When SR-IOV enablement fails during mlx5_sriov_enable(), HCA's are left
in enabled stage because mlx5_device_disable_sriov() relies on num_vfs
from PCI core.

mlx5_sriov_enable()
  mlx5_device_enable_sriov()
  pci_enable_sriov() <- Fails

Hence, to overcome above issues,
(a) Read num_vfs before disabling SR-IOV and use it.
(b) Use num_vfs given when enabling sriov in error unwinding path.

net/mlx5: Add new chain for netfilter flow table offload

Netfilter tables (nftables) implements a software datapath that
comes after tc ingress datapath. The datapath supports offloading
such rules via the flow table offload API.

This API is currently only used by NFT and it doesn't provide the
global priority in regards to tc offload, so we assume offloading such
rules must come after tc. It does provide a flow table priority
parameter, so we need to provide some supported priority range.

For that, split fastpath prio to two, flow table offload and tc offload,
with one dedicated priority chain for flow table offload.

Next patch will re-use the multi chain API to access this chain by
allowing access to this chain by the fdb_sub_namespace.

Tc chains are implemented by creating a chained prio steering type, and

Currently, all namespaces in a prio start at the parent prio level.
But since we can jump from chain (namespace) to another chain in the

So we created unused prios to account for levels in previous namespaces.

Fix that by accumulating the namespaces levels if we are inside a chained
type prio, and removing the unused prios.

Implement get_link_ksettings for VXLAN and bridge

Mesh routing protocol batman-adv (in particular the new BATMAN_V algorithm)

metric for wired links. In the mesh framework Gluon [1], we layer VXLAN

====================
netfilter flowtable hardware offload

The following patchset adds hardware offload support for the flowtable
infrastructure [1]. This infrastructure provides a fast datapath for
the classic Linux forwarding path that users can enable through policy,
eg.

 table inet x {
      flowtable f {
               hook ingress priority 10 devices = { eth0, eth1 }
       flags offload
      }
      chain y {
               type filter hook forward priority 0; policy accept;
               ip protocol tcp flow offload @f
      }
 }

This example above enables the fastpath for TCP traffic between devices
eth0 and eth1. Users can turn on the hardware offload through the
'offload' flag from the flowtable definition. If this new flag is not
specified, the software flowtable datapath is used.

This patchset is composed of 4 preparation patches:

   room to extend this infrastructure, eg. accelerate bridge forwarding.

And 2 patches to add the hardware offload control and data planes:

   hardware offload. This includes a new NFTA_FLOWTABLE_FLAGS netlink
   attribute to convey the optional NF_FLOWTABLE_HW_OFFLOAD flag.
   API available at net/core/flow_offload.h to represent the flow
   through two flow_rule objects to configure an exact 5-tuple matching
   on each direction plus the corresponding forwarding actions, that is,
   the MAC address, NAT and checksum updates; and port redirection in
   order to configure the hardware datapath. This patch only supports
   for IPv4 support and statistics collection for flow aging as an initial
   step.

This patchset introduces a new flow_block callback type that needs to be
set up to configure the flowtable hardware offload.

The first client of this infrastructure follows up after this batch.
I would like to thank Mellanox for developing the first upstream driver
to use this infrastructure.

Pankaj Sharma contributes two patches for the m_can driver, the first
one adds support for one shot mode, the other support for handling
arbitration errors.

Followed by four patches by YueHaibing, switching the grcan, ifi, rcar,

Zhang's patch prepares the rx-offload helper for CAN-FD support. The rx
offload users flexcan and ti_hecc are converted accordingly.

devlink: Allow large formatted message of binary output

Devlink supports pair output of name and value. When the value is
binary, it must be presented in an array. If the length of the binary
value exceeds fmsg limitation, break the value into chunks internally.
