net: dsa: mv88e6xxx: implement VLAN filtering
This patchset fixes hardware bridging for non 802.1Q aware systems.
The mv88e6xxx DSA driver currently depends on CONFIG_VLAN_8021Q and
CONFIG_BRIDGE_VLAN_FILTERING enabled for correct bridging between switch ports.
Patch 1/9 adds support for the VLAN filtering switchdev attribute in DSA.
Patchs 2/9 and 3/9 add helper functions for the following patches.
Patchs 4/9 to 6/9 assign dynamic address databases to VLANs, ports, and
bridge groups (the lowest available FID is cleared and assigned), and thus
restore support for per-port FDB operations.
Patchs 7/9 to 9/9 refine ports isolation and setup 802.1Q on user demand.
With this patchset, ports get correctly bridged and the driver behaves as
expected, with or without 802.1Q support.
With CONFIG_VLAN_8021Q enabled, setting a default PVID to the bridge correctly
propagates the corresponding VLAN, in addition to the hardware bridging:
# echo 42 > /sys/class/net/<bridge>/bridge/default_pvid
But considering CONFIG_BRIDGE_VLAN_FILTERING enabled, the hardware VLAN
filtering is enabled on all bridge members only when the user requests it:
# echo 1 > /sys/class/net/<bridge>/bridge/vlan_filtering

Now that ports isolation is correctly configured when joining or leaving

The In Chip Port Based VLAN Table contains bits used to restrict which

With the VLAN filtering enabled, these tables work in conjunction with
the VLAN Table Unit to allow egressing frames.

basic hardware bridging to work, it is necessary to restore a fine

Introduce devlink interface and first drivers to use it
There a is need for some userspace API that would allow to expose things
that are not directly related to any device class like net_device of
ib_device, but rather chip-wide/switch-ASIC-wide stuff.
Use cases:
1) get/set of port type (Ethernet/InfiniBand)
2) setting up port splitters - split port into multiple ones and squash again,
enables usage of splitter cable
3) setting up shared buffers - shared among multiple ports within
one chip (work in progress)
4) configuration of switch wide properties - resources division etc - This will
allow to pass configuration that is unacceptable to be passed as
a module option.
First patch of this set introduces a new generic Netlink based interface,
called "devlink". It is similar to nl80211 model and it is heavily
influenced by it, including the API definition. The devlink introduction patch
implements use cases 1) and 2). Other 2 are in development atm and will
be addressed by follow-ups.
It is very convenient for drivers to use devlink, as you can see in other
patches in this set.
Counterpart for devlink is userspace tool for now called "dl". Command line
interface and outputs are derived from "ip" tool so it should be easy
for users to get used to it.
It is available here as a standalone tool for now:
https://github.com/jpirko/devlink
After this is merge in kernel, I will include the "dl" or "devlink" tool
into iproute2 toolset.
Port type setting example:
myhost:~$ dl help
Usage: dl [ OPTIONS ] OBJECT { COMMAND | help }
where OBJECT := { dev | port | monitor }
OPTIONS := { -v/--verbose }
myhost:~$ dl dev help
Usage: dl dev show [DEV]
myhost:~$ dl dev show
pci/0000:01:00.0
myhost:~$ dl port help
Usage: dl port show [DEV/PORT_INDEX]
Usage: dl port set DEV/PORT_INDEX [ type { eth | ib | auto} ]
Usage: dl port split DEV/PORT_INDEX count
Usage: dl port unsplit DEV/PORT_INDEX
myhost:~$ dl port show
pci/0000:01:00.0/1: type ib ibdev mlx4_0
pci/0000:01:00.0/2: type ib ibdev mlx4_0
myhost:~$ sudo dl port set pci/0000:01:00.0/1 type eth
myhost:~$ dl port show
pci/0000:01:00.0/1: type eth netdev ens4
pci/0000:01:00.0/2: type ib ibdev mlx4_0
myhost:~$ sudo dl port set ens4 type auto
myhost:~$ dl port show
pci/0000:01:00.0/1: type eth(auto) netdev ens4
pci/0000:01:00.0/2: type ib ibdev mlx4_0

The port netdevs are each associated with a different local port number
in the device. These local ports are grouped into groups of 4 (e.g.
(1-4), (5-8)) called clusters. The cluster constitutes the one of two
possible modules they can be mapped to. This mapping is board-specific
and done by the device's firmware during init.
When splitting a port by 4, the device requires us to first unmap all
the ports in the cluster and then map each to a single lane in the module
associated with the port netdev used as the handle for the operation.
This means that two port netdevs will disappear, as only 100Gb/s (4
lanes) ports can be split and we are guaranteed to have two of these
((1, 3), (5, 7) etc.) in a cluster.
When unsplit occurs we need to reinstantiate the two original 100Gb/s
ports and map each to its origianl module. Therefore, during driver init
store the initial local port to module mapping, so it can be used later
during unsplitting.
Note that a by 2 split doesn't require us to store the mapping, as we
only need to reinstantiate one port whose module is known.

tc software only
This adds a software only flag to tc but incorporates a bunch of comments
from the original attempt at this.
First instead of having the offload decision logic be embedded in cls_u32
I lifted into cls_pkt.h so it can be used anywhere and named the flag
TCA_CLS_FLAGS_SKIP_HW (Thanks Jiri ;)
In order to do this I put the flag defines in pkt_cls.h as well. However
it was suggested that perhaps these flags could be lifted into the
upper layer of TCA_ as well but I'm afraid this can not be done with
existing tc design as far as I can tell. The problem is the filters are
packed and unpacked in the classifier specific code and pushing the flags
through the high level doesn't seem easily doable. And we already have
this design where classifiers handle generic options such as actions and
policers. So I think adding one more thing here is OK as 'tc', et. al.
already know how to handle this type of thing.

In the initial implementation the only way to stop a rule from being
inserted into the hardware table was via the device feature flag.
However this doesn't work well when working on an end host system
where packets are expect to hit both the hardware and software
datapaths.
For example we can imagine a rule that will match an IP address and
increment a field. If we install this rule in both hardware and
software we may increment the field twice. To date we have only
added support for the drop action so we have been able to ignore
these cases. But as we extend the action support we will hit this
example plus more such cases. Arguably these are not even corner
cases in many working systems these cases will be common.
To avoid forcing the driver to always abort (i.e. the above example)
this patch adds a flag to add a rule in software only. A careful
user can use this flag to build software and hardware datapaths
that work together. One example we have found particularly useful
is to use hardware resources to set the skb->mark on the skb when
the match may be expensive to run in software but a mark lookup
in a hash table is cheap. The idea here is hardware can do in one
lookup what the u32 classifier may need to traverse multiple lists
and hash tables to compute. The flag is only passed down on inserts.
On deletion to avoid stale references in hardware we always try
to remove a rule if it exists.
The flags field is part of the classifier specific options. Although
it is tempting to lift this into the generic structure doing this
proves difficult do to how the tc netlink attributes are implemented
along with how the dump/change routines are called. There is also
precedence for putting seemingly generic pieces in the specific
classifier options such as TCA_U32_POLICE, TCA_U32_ACT, etc. So
although not ideal I've left FLAGS in the u32 options as well as it
simplifies the code greatly and user space has already learned how
to manage these bits ala 'tc' tool.
Another thing if trying to update a rule we require the flags to
be unchanged. This is to force user space, software u32 and
the hardware u32 to keep in sync. Thanks to Simon Horman for
catching this case.

bridge/ovs: avoid skb head copy on frame forwarding
Currently, while when an OVS or Linux bridge is used to forward frames towards
some tunnel device, a skb_head_copy() may occur if the ingress device do not
provide enough headroom for the tx encapsulation.
This patch series tries to address the issue implementing a new ndo operation to
allow the master device to control the headroom used when allocating the skb on
frame reception.
Said operation is used by the Linux bridge to notify the bridged ports of
needed_headroom changes, and similar bookkeeping and behaviour is also added to
openvswitch, on a per datapath basis.
Finally, the operation is implemented for veth and tun device, which give
performance improvement in the 6-12% range when forwarding frames from said
devices towards a vxlan tunnel.
v2:
- fix netdev_get_fwd_headroom() behaviour
- remove some code duplication with the netdev_set_rx_headroom() and
netdev_reset_rx_headroom() helpers
- handle headroom reset on [v]port removal/deletion
- initialize tun align to the old default value

The measured improvement when forwarding towards a vxlan dev with
frame size below the egress device MTU is as follow:
vxlan over ipv6, bridged: +6%
vxlan over ipv6, ovs: +7%
