This patch adds containers and mutators for the major ieee802154_llsec
structures to mac802154. Most of the (rather simple) ieee802154_llsec
structs are wrapped only to provide an rcu_head for orderly disposal,
but some structs - llsec keys notably - require more complex
bookkeeping.
Since each llsec key may be referenced by a number of llsec key table
entries (with differing key ids, but the same actual key), we want to
save memory and not allocate crypto transforms for each entry in the
table. Thus, the mac802154 llsec key is reference-counted instead.
Further, each key will have four associated crypto transforms - three
CCM transforms for the authsizes 4/8/16 and one CTR transform for
unauthenticated encryption. If we had a CCM* transform that allowed
authsize 0, and authsize as part of requests instead of transforms, this
would not be necessary.

excessive and not particularly useful. The DeviceDescriptorHandleList

Add DT support for fixed PHYs
Here is a fourth version of the patch set that adds a Device Tree
binding and the related code to support fixed PHYs. I'm hoping to get
this merged in 3.16.
Changes since v3:
* Rebased on top of v3.15-rc5
* In patch "net: phy: decouple PHY id and PHY address in fixed PHY
driver", changed the PHY ID of fixed PHYs from 0xdeadbeef to 0x0,
as suggested by Grant Likely.
* Fixed the !CONFIG_PHY_FIXED case in patch "net: phy: extend fixed
driver with fixed_phy_register()". Noticed by Florian Fainelli.
* Added Acked-by from Grant Likely and Florian Fainelli on patch
"net: phy: extend fixed driver with fixed_phy_register()".
* Reworked the new fixed-link DT binding to be just a sub-node of the
Ethernet MAC node, and not a node referenced by the 'phy'
property. This was requested by Grant Likely.
* Reworked the code implementing the new DT binding to also make it
accept the old, single property based, DT binding.
* Added a patch that actually uses the new fixed link DT binding for
the Armada XP Matrix board.
Changes since v2:
* Rebased on top of v3.14-rc1, and re-tested on hardware.
* Removed the RFC tag, since there seems to be some real interest in
this feature, and the code has gone through several iterations
already.
* The error handling in fixed_phy_register() has been fixed.
Changes since v1:
* Instead of using a 'fixed-link' property inside the Ethernet device
DT node, with a fairly cryptic succession of integer values, we now
use a PHY subnode under the Ethernet device DT node, with explicit
properties to configure the duplex, speed, pause and other PHY
properties.
* The PHY address is automatically allocated by the kernel and no
longer visible in the Device Tree binding.
* The PHY device is created directly when the network driver calls
of_phy_connect_fixed_link(), and associated to the PHY DT node,
which allows the existing of_phy_connect() function to work,
without the need to use the deprecated of_phy_connect_fixed_link().

Some Ethernet MACs have a "fixed link", and are not connected to a
normal MDIO-managed PHY device. For those situations, a Device Tree
binding allows to describe a "fixed link" using a special PHY node.
This patch adds:
* A documentation for the fixed PHY Device Tree binding.
* An of_phy_is_fixed_link() function that an Ethernet driver can call
on its PHY phandle to find out whether it's a fixed link PHY or
not. It should typically be used to know if
of_phy_register_fixed_link() should be called.
* An of_phy_register_fixed_link() function that instantiates the
fixed PHY into the PHY subsystem, so that when the driver calls
of_phy_connect(), the PHY device associated to the OF node will be
found.
These two additional functions also support the old fixed-link Device
Tree binding used on PowerPC platforms, so that ultimately, the
network device drivers for those platforms could be converted to use
of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
of_phy_connect_fixed_link(), while keeping compatibility with their
respective Device Tree bindings.

The existing fixed_phy_add() function has several drawbacks that
prevents it from being used as is for OF-based declaration of fixed
PHYs:
* The address of the PHY on the fake bus needs to be passed, while a
dynamic allocation is desired.
* Since the phy_device instantiation is post-poned until the next
mdiobus scan, there is no way to associate the fixed PHY with its
OF node, which later prevents of_phy_connect() from finding this
fixed PHY from a given OF node.
To solve this, this commit introduces fixed_phy_register(), which will
allocate an available PHY address, add the PHY using fixed_phy_add()
and instantiate the phy_device structure associated with the provided
OF node.

Until now, the fixed_phy_add() function was taking as argument
'phy_id', which was used both as the PHY address on the fake fixed
MDIO bus, and as the PHY id, as available in the MII_PHYSID1 and
MII_PHYSID2 registers. However, those two informations are completely
unrelated.
This patch decouples them. The PHY id of fixed PHYs is hardcoded to be
0x0. Ideally, a really reserved value would be nicer, but there
doesn't seem to be an easy of making sure a dummy value can be
assigned to the Linux kernel for such usage.
The PHY address remains passed by the caller of phy_fixed_add().

====================
bridge: Non-promisc bridge ports support
This series adds functionality to the bridge device to enable
operations without setting all ports to promiscuous mode.
The basic concept is this. The bridge keeps track of the ports
that support learning and flooding packets to unknown destinations.
We call these ports auto-discovery ports since they automatically
discover who is behind them through learning and flooding.
If flooding and learning are disabled via flags, then the port
requires static configuration to tell it which mac addresses
are behind it. This is accomplished through adding of fdbs.
These fdbs should be static as dynamic fdbs can expire and systems
will become unreachable due to lack of flooding.
If the user marks all ports as needing static configuration then
we can safely make them non-promiscuous since we will know all the
information about them.
If the user leaves only 1 port as automatic, then we can mark
that port as not-promiscuous as well. One could think of
this a edge relay similar to what's support by embedded switches
in SRIOV devices. Since we have all the information about the
other ports, we can just program the mac addresses into the
single automatic port to receive all necessary traffic.
More information about this is patch 6.
In other cases, we keep all ports promiscuous as before.
There are some other cases when promiscuous mode has to be turned
back on. One is when the bridge itself if placed in promiscuous
mode (user sets promisc flag). The other is if vlan filtering is
turned off. Since this is the default configuration, the default
bridge operation is not changed.
Changes since v2:
- White space and spelling fixes from Michael Tsirkin
- Squash patches 6, 7 and 8 to prevent bisect breakage.
Changes since v1:
- Address issues rasied by Stephen Heminger
- Address initializer comments raised by Sergey Shtylyov
- Rebased recent net-next.
Changes since rfc v2:
- Better description of in the commit logs
- Leave port in promiscuous mode if IFF_UNICAST_FLT is disabled on the
device.
- Fix issue with flag masking
- Rework patch ordering a bit.
Changes since rfc v1:
- Removed private list. We now traverse the fdb hashtable itself
to write necessary addresses to the ports (Stephen's concern)
- Add learning flag to the mask for flags that decides if the port
is 'auto' or not (suggest by MST and Jamal).
- Simplified tracking of such ports at the cost of a loop over all
ports (suggested by MST)
I've played with quite a large number of ports and the current approach
seems to work fairly well.

There exist configurations where the administrator or another management
entity has the foreknowledge of all the mac addresses of end systems
that are being bridged together.
In these environments, the administrator can statically configure known
addresses in the bridge FDB and disable flooding and learning on ports.
This makes it possible to turn off promiscuous mode on the interfaces
connected to the bridge.
Here is why disabling flooding and learning allows us to control
promiscuity:
Consider port X. All traffic coming into this port from outside the
bridge (ingress) will be either forwarded through other ports of the
bridge (egress) or dropped. Forwarding (egress) is defined by FDB
entries and by flooding in the event that no FDB entry exists.
In the event that flooding is disabled, only FDB entries define
the egress. Once learning is disabled, only static FDB entries
provided by a management entity define the egress. If we provide
information from these static FDBs to the ingress port X, then we'll
be able to accept all traffic that can be successfully forwarded and
drop all the other traffic sooner without spending CPU cycles to
process it.
Another way to define the above is as following equations:
ingress = egress + drop
expanding egress
ingress = static FDB + learned FDB + flooding + drop
disabling flooding and learning we a left with
ingress = static FDB + drop
By adding addresses from the static FDB entries to the MAC address
filter of an ingress port X, we fully define what the bridge can
process without dropping and can thus turn off promiscuous mode,
thus dropping packets sooner.
There have been suggestions that we may want to allow learning
and update the filters with learned addresses as well. This
would require mac-level authentication similar to 802.1x to
prevent attacks against the hw filters as they are limited
resource.
Additionally, if the user places the bridge device in promiscuous mode,
all ports are placed in promiscuous mode regardless of the changes
to flooding and learning.
Since the above functionality depends on full static configuration,
we have also require that vlan filtering be enabled to take
advantage of this. The reason is that the bridge has to be
able to receive and process VLAN-tagged frames and the there
are only 2 ways to accomplish this right now: promiscuous mode
or vlan filtering.

By default, ports on the bridge are capable of automatic
discovery of nodes located behind the port. This is accomplished
via flooding of unknown traffic (BR_FLOOD) and learning the
mac addresses from these packets (BR_LEARNING).
If the above functionality is disabled by turning off these
flags, the port requires static configuration in the form
of static FDB entries to function properly.
This patch adds functionality to keep track of all ports

Keep kernel flow stats for each NUMA node rather than each (logical)
CPU. This avoids using the per-CPU allocator and removes most of the
kernel-side OVS locking overhead otherwise on the top of perf reports
and allows OVS to scale better with higher number of threads.
With 9 handlers and 4 revalidators netperf TCP_CRR test flow setup
rate doubles on a server with two hyper-threaded physical CPUs (16
logical cores each) compared to the current OVS master. Tested with
non-trivial flow table with a TCP port match rule forcing all new
connections with unique port numbers to OVS userspace. The IP
addresses are still wildcarded, so the kernel flows are not considered
as exact match 5-tuple flows. This type of flows can be expected to
appear in large numbers as the result of more effective wildcarding
made possible by improvements in OVS userspace flow classifier.

There is a small increase in kernel spinlock overhead due to the same
spinlock being shared between multiple cores of the same physical CPU,
but that is barely visible in the netperf TCP_CRR test performance
(maybe ~1% performance drop, hard to tell exactly due to variance in
the test results), when testing for kernel module throughput (with no
userspace activity, handful of kernel flows).
On flow setup, a single stats instance is allocated (for the NUMA node
0). As CPUs from multiple NUMA nodes start updating stats, new
NUMA-node specific stats instances are allocated. This allocation on
the packet processing code path is made to never block or look for
emergency memory pools, minimizing the allocation latency. If the
allocation fails, the existing preallocated stats instance is used.
Also, if only CPUs from one NUMA-node are updating the preallocated
stats instance, no additional stats instances are allocated. This
eliminates the need to pre-allocate stats instances that will not be
used, also relieving the stats reader from the burden of reading stats
that are never used.
