Netfilter updates for net-next
The following batch contains netfilter updates for net-next. Basically,
enhancements for xt_recent, skip zeroing of timer in conntrack, fix
linking problem with recent redirect support for nf_tables, ipset
updates and a couple of cleanups. More specifically, they are:
1) Rise maximum number per IP address to be remembered in xt_recent
while retaining backward compatibility, from Florian Westphal.
2) Skip zeroing timer area in nf_conn objects, also from Florian.
3) Inspect IPv4 and IPv6 traffic from the bridge to allow filtering using
using meta l4proto and transport layer header, from Alvaro Neira.
4) Fix linking problems in the new redirect support when CONFIG_IPV6=n
and IP6_NF_IPTABLES=n.
And ipset updates from Jozsef Kadlecsik:
5) Support updating element extensions when the set is full (fixes
netfilter bugzilla id 880).
6) Fix set match with 32-bits userspace / 64-bits kernel.
7) Indicate explicitly when /0 networks are supported in ipset.
8) Simplify cidr handling for hash:*net* types.
9) Allocate the proper size of memory when /0 networks are supported.
10) Explicitly add padding elements to hash:net,net and hash:net,port,
because the elements must be u32 sized for the used hash function.
Jozsef is also cooking ipset RCU conversion which should land soon if
they reach the merge window in time.

Intel Wired LAN Driver Updates 2014-12-05
This series contains updates to ixgbe and ixgbevf.
Alex provides a couple of patches to cleanup ixgbe. First cleans up the
page reuse code getting it into a state where all the workarounds needed
are in place as well as cleaning up a few minor oversights such as using
__free_pages instead of put_page to drop a locally allocated page. Then
cleans up the tail writes for the ixgbe descriptor queues.
Mark Peterson adds support to lookup MAC addresses in Open Firmware or
IDPROM.
Emil provides patches for ixgbe and ixgbevf to fix an issue on rmmod and
to add support for X550 in the VF driver. First removes the read/write
operations to the CIAA/D registers since it can block access to the PCI
config space and make use of standard kernel functions for accessing the
PCI config space. Then fixes an issue where the driver has logic to free
up used data in case any of the checks in ixgbe_probe() fail, however
there is a similar set of cleanups that can occur on driver unload in
ixgbe_remove() which can cause the rmmod command to crash.

of X550 support into the ixgbe driver.

introduce rocker switch driver with hardware accelerated datapath api - phase 1: bridge fdb offload
This patchset is just the first phase of switch and switch-ish device
support api in kernel. Note that the api will extend.
So what this patchset includes:
- introduce switchdev api skeleton for implementing switch drivers
- introduce rocker switch driver which implements switchdev api fdb and
bridge set/get link ndos
As to the discussion if there is need to have specific class of device
representing the switch itself, so far we found no need to introduce that.
But we are generally ok with the idea and when the time comes and it will
be needed, it can be easily introduced without any disturbance.
This patchset introduces switch id export through rtnetlink and sysfs,
which is similar to what we have for port id in SR-IOV. I will send iproute2
patchset for showing the switch id for port netdevs once this is applied.
This applies also for the PF_BRIDGE and fdb iproute2 patches.
iproute2 patches are now available here:
https://github.com/jpirko/iproute2-rocker
For detailed description and version history, please see individual patches.
In v4 I reordered the patches leaving rocker patches on the end of the patchset.
In v5 I only fixed whitespace issues of patch #13

rocker: implement L2 bridge offloading
Add L2 bridge offloading support to rocker driver. Here, the Linux bridge
driver is used to collect swdev ports into a tagged (or untagged) VLAN
bridge. The switchdev will offload from the bridge driver the following L2
bridging functions:
- Learning of neighbor MAC addresses on VLAN X Learned mac/vlan is
installed in bridge FDB. (And removed when device unlearns mac/vlan).
Learning must be turned off on each bridge port to disable the feature in
the bridge driver.
- Flooding of multicast/broadcast and unknown unicast pkts to (STP)
active ports in bridge. The bridge driver is unaware of the flooding happening
at the device level. Flooding must be turned off on each bridge port to
disable the feature on the bridge driver.
- STP port state is pushed down to driver/device. The bridge still processes
STP BDPUs and maintains port STP state (for all VLANs in bridge), but
the driver/device must be notified of port STP state change to program
the device.
Multiple (VLAN) bridges are supported. The device (implemented per
the OF-DPA spec) must use a portion of the VLAN namespace for
internal VLANs. Right now, the upper 255 VLANs (0xf00 to 0xffe) are
used as internal VLAN IDs for untagged traffic and are not available
as port VLANs.
The driver uses the following interfaces:
1. To track VLAN add/del on ports in bridge:
.ndo_vlan_rx_add_vid
.ndo_vlan_rx_kill_vid
2. To track port add/del membership in bridge:
NETDEV_CHANGEUPPER netdevice notifier
3. To catch static FDB entries installed on bridge/vlan by user using netlink:
.ndo_fdb_add
.ndo_fdb_del
4. To be notified on port STP state change:
.ndo_switch_port_stp_update

rocker: implement rocker ofdpa flow table manipulation
The rocker driver maintains 4 hash tables: flows, groups, FDB, and VLANs.
Flow and group tables track the entries installed to OF-DPA tables,
per the OF-DPA spec. See OF-DPA spec for full description of fields
in each flow and group table. New table entries are pushed to the
device with ADD cmd. Updated entries are pushed to the device with
MOD cmd. For flow table entries, a crc32 key is made from fields of
the particular field. For group table entries, the group_id is used
as the key.
The FDB table tracks fdb entries learned by the device or manually
pushed to the bridge by the user. A crc32 key is made from the
port/mac/vlan tuple for the fdb entry.
The VLAN table tracks the ifindex-to-internal-vlan mapping for
untagged pkts. On ingress, an untagged pkt is inserted with an
internal VLAN ID based on the input port's current internal VLAN ID.
The input port's internal VLAN will either be referenced by the port's
ifindex, if not bridged, or the containing bridge's ifindex, if
bridged. Since the ifindex space isn't within a fixed range, uses a
hash table (with ifindex as key) to track internal VLAN ID for a given
ifindex. The internal VLAN ID range is fixed and currently uses the
upper 255 VLAN IDs, starting at 0xf00.

bridge: add API to notify bridge driver of learned FBD on offloaded device
When the swdev device learns a new mac/vlan on a port, it sends some async
notification to the driver and the driver installs an FDB in the device.
To give a holistic system view, the learned mac/vlan should be reflected
in the bridge's FBD table, so the user, using normal iproute2 cmds, can view
what is currently learned by the device. This API on the bridge driver gives
a way for the swdev driver to install an FBD entry in the bridge FBD table.
(And remove one).
This is equivalent to the device running these cmds:
bridge fdb [add|del] <mac> dev <dev> vid <vlan id> master
This patch needs some extra eyeballs for review, in paricular around the
locking and contexts.

There is a potential race when probing the TLB in TLBL/M/S exception
handlers for a matching entry. Between the time we hit a TLBL/S/M
exception and the time we get to execute the TLBP instruction, the
HTW may have replaced the TLB entry we are interested in hence the TLB

ARM: 8226/1: cacheflush: get rid of restarting block
We cannot restart cacheflush safely if a process provides user-defined
signal handler and signal is pending. In this case -EINTR is returned
and it is expected that process re-invokes syscall. However, there are
a few problems with that:
* looks like nobody bothers checking return value from cacheflush
* but if it did, we don't provide the restart address for that, so the
process has to use the same range again
* ...and again, what might lead to looping forever
So, remove cacheflush restarting code and terminate cache flushing
as early as fatal signal is pending.

ARM: 8222/1: mvebu: enable strex backoff delay
Under extremely rare conditions, in an MPCore node consisting of at
least 3 CPUs, two CPUs trying to perform a STREX to data on the same
shared cache line can enter a livelock situation.
This patch enables the HW mechanism that overcomes the bug. This fixes
the incorrect setup of the STREX backoff delay bit due to a wrong
description in the specification.
Note that enabling the STREX backoff delay mechanism is done by
leaving the bit *cleared*, while the bit was currently being set by
the proc-v7.S code.
[Thomas: adapt to latest mainline, slightly reword the commit log, add
stable markers.]

ARM: tegra: irq: fix buggy usage of irq_data irq field
The crazy gic_arch_extn thing that Tegra uses contains multiple
references to the irq field in struct irq_data, and uses this
to directly poke hardware register.
But irq is the *virtual* irq number, something that has nothing
to do with the actual HW irq (stored in the hwirq field). And once
we put the stacked domain code in action, the whole thing explodes,
as these two values are *very* different:

====================
net: bcmgenet: EEE support
This patch series add EEE support to the Broadcom GENET driver, first patch
basically adds register definitions for the hardware, the second patch does the
actual implementation and hooks the {get,set}_eee ethtool callbacks, the last
patch adds auto-negotiation restart capability.

net: bcmgenet: support restarting auto-negotiation
Hook a nway_reset ethtool callback to allow restarting the
auto-negotiation process when asked to. We defer to the PHY library call
to do the heavy lifting.

net: bcmgenet: add EEE support
Allow enabling and disabling EEE using the designated ethtool getters
and setters. GENET allows controlling EEE at the UniMAC, RBUF and TBUF
levels. We also take care of restoring EEE after a suspend/resume cycle
if it was enabled prior to suspending.
