====================
bonding: add more netlink attributes
v2:
Addressed v1 review comments. In particular, Jay's concern about
current sysfs ordering limitations carrying over to iproute. Netlink
attributes are processed in a priority order in
bond_netlink.c:bond_changelink(). Lower priority attributes can't undo
higher priority attributes when attempting to set both with iproute
command. For example, this command will fail:
ip link add bond1 type bond mode active-backup miimon 10 arp_interval 10
Because we're trying to create a new bond to use incompatible miimon
and ARP interval attributes. However, if attributes are applied
one-at-a-time, previously applied attributes can be overridden:
ip link add bond1 type bond mode active-backup miimon 10
ip link set dev bond1 type bond arp_interval 10
These two commands succeed. The bond is first created to use miimon.
Next, the bond is converted to use ARP interval, which undoes miimon.
v1:
Following Jiri Pirko's lead, add more bonding netlink attributes. Sending
matching iproute2 patch separately. sysfs access to attributes is
retained.

net-gro: Prepare GRO stack for the upcoming tunneling support
This patch modifies the GRO stack to avoid the use of "network_header"
and associated macros like ip_hdr() and ipv6_hdr() in order to allow
an arbitary number of IP hdrs (v4 or v6) to be used in the
encapsulation chain. This lays the foundation for various IP
tunneling support (IP-in-IP, GRE, VXLAN, SIT,...) to be added later.
With this patch, the GRO stack traversing now is mostly based on
skb_gro_offset rather than special hdr offsets saved in skb (e.g.,
skb->network_header). As a result all but the top layer (i.e., the
the transport layer) must have hdrs of the same length in order for
a pkt to be considered for aggregation. Therefore when adding a new
encap layer (e.g., for tunneling), one must check and skip flows
(e.g., by setting NAPI_GRO_CB(p)->same_flow to 0) that have a
different hdr length.
Note that unlike the network header, the transport header can and
will continue to be set by the GRO code since there will be at
most one "transport layer" in the encap chain.

Merge branch 'macvtap_capture'
Vlad Yasevich says:
====================
Add packet capture support on macvtap device
Change from RFC:
- moved to the rx_handler approach.
This series adds support for packet capturing on macvtap device.
The initial approach was to simply export the capturing code as
a function from the core network. While simple, it was not
a very architecturally clean approach.
The new appraoch is to provide macvtap with its rx_handler which can
is attached to the macvtap device itself. Macvlan will simply requeue
the packet with an updated skb->dev. BTW, macvlan layer already does this
for macvlan devices. So, now macvtap and macvlan have almost the
same exact input path.
I've toyed with short-circuting the input path for macvtap by returning
RX_HANDLER_ANOTHER, but that just made the code more complicated and
didn't provide any kind of measurable gain (at least according to
netperf and perf runs on the host).
To see if there was a performance regression, I ran 1, 2 and 4 netperf
STREAM and MAERTS tests agains the VM from both remote host and another
guest on the same system. The command ran was
netperf -H $host -t $test -l 20 -i 10 -I 95 -c -C
The numbers I was getting with the new code were consistently very
slightly (1-2%) better then the old code. I don't consider this
an improvement, but it's not a regression! :)
Running 'perf record' on the host didn't show any new hot spots
and cpu utilization stayed about the same. This was better
then I expected from simply looking at the code.

macvtap: Add support of packet capture on macvtap device.
Macvtap device currently doesn not allow a user to capture
traffic on due to the fact that it steals the packets
from the network stack before the skb->dev is set correctly
on the receive side, and that use uses macvlan transmit
path directly on the send side. As a result, we never
get a change to give traffic to the taps while the correct
device is set in the skb.
This patch makes macvtap device behave almost exaclty like
macvlan. On the send side, we switch to using dev_queue_xmit().
On the receive side, to deliver packets to macvtap, we now
use netif_rx and dev_forward_skb just like macvlan. The only
differnce now is that macvtap has its own rx_handler which is
attached to the macvtap netdev. It is here that we now steal
the packet and provide it to the socket.
As a result, we can now capture traffic on the macvtap device:
tcpdump -i macvtap0
It also gives us the abilit to add tc actions to the macvtap
device and actually utilize different bandwidth management
queues on output.

filter: bpf_asm: add minimal bpf asm tool
There are a couple of valid use cases for a minimal low-level bpf asm
like tool, for example, using/linking to libpcap is not an option, the
required BPF filters use Linux extensions that are not supported by
libpcap's compiler, a filter might be more complex and not cleanly
implementable with libpcap's compiler, particular filter codes should
be optimized differently than libpcap's internal BPF compiler does,
or for security audits of emitted BPF JIT code for prepared set of BPF
instructions resp. BPF JIT compiler development in general.
Then, in such cases writing such a filter in low-level syntax can be
an good alternative, for example, xt_bpf and cls_bpf users might have
requirements that could result in more complex filter code, or one that
cannot be expressed with libpcap (e.g. different return codes in
cls_bpf for flowids on various BPF code paths).
Moreover, BPF JIT implementors may wish to manually write test cases
in order to verify the resulting JIT image, and thus need low-level
access to BPF code generation as well. Therefore, complete the available
toolchain for BPF with this small bpf_asm helper tool for the tools/net/

filter: bpf_dbg: add minimal bpf debugger
This patch adds a minimal BPF debugger that "emulates" the kernel's
BPF engine (w/o extensions) and allows for single stepping (forwards
and backwards through BPF code) or running with >=1 breakpoints through
selected or all packets from a pcap file with a provided user filter
in order to facilitate verification of a BPF program. When a breakpoint
is being hit, it dumps all register contents, decoded instructions and
in case of branches both decoded branch targets as well as other useful
information.
Having this facility is in particular useful to verify BPF programs
against given test traffic *before* attaching to a live system.
With the general availability of cls_bpf, xt_bpf, socket filters,
team driver and e.g. PTP code, all BPF users, quite often a single
more complex BPF program is being used. Reasons for a more complex
BPF program are primarily to optimize execution time for making a
verdict when multiple simple BPF programs are combined into one in
order to prevent parsing same headers multiple times. In particular,
for cls_bpf that can have various return paths for encoding flowids,
and xt_bpf to come to a fw verdict this can be the case.
Therefore, as this can result in more complex and harder to debug
code, it would be very useful to have this minimal tool for testing
purposes. It can also be of help for BPF JIT developers as filters
are "test attached" to the kernel on a temporary socket thus
triggering a JIT image dump when enabled. The tool uses an interactive
libreadline shell with auto-completion and history support.

ipv6: router reachability probing
RFC 4191 states in 3.5:
When a host avoids using any non-reachable router X and instead sends
a data packet to another router Y, and the host would have used
router X if router X were reachable, then the host SHOULD probe each
such router X's reachability by sending a single Neighbor
Solicitation to that router's address. A host MUST NOT probe a
router's reachability in the absence of useful traffic that the host
would have sent to the router if it were reachable. In any case,
these probes MUST be rate-limited to no more than one per minute per
router.
Currently, when the neighbour corresponding to a router falls into
NUD_FAILED, it's never considered again. Introduce a new rt6_nud_state
value, RT6_NUD_FAIL_PROBE, which suggests the route should not be used but
should be probed with a single NS. The probe is ratelimited by the existing
code. To better distinguish meanings of the failure values, rename
RT6_NUD_FAIL_SOFT to RT6_NUD_FAIL_DO_RR.

tipc: remove unused 'blocked' flag from tipc_link struct
In early versions of TIPC it was possible to administratively block
individual links through the use of the member flag 'blocked'. This
functionality was deemed redundant, and since commit 7368dd ("tipc:
clean out all instances of #if 0'd unused code"), this flag has been
unused.
In the current code, a link only needs to be blocked for sending and
reception if it is subject to an ongoing link failover. In that case,
it is sufficient to check if the number of expected failover packets
is non-zero, something which is done via the funtion 'link_blocked()'.
This commit finally removes the redundant 'blocked' flag completely.

tipc: relocate common functions from media to bearer
Currently, registering a TIPC stack handler in the network device layer
is done twice, once for Ethernet (eth_media) and Infiniband (ib_media)
repectively. But, as this registration is not media specific, we can
avoid some code duplication by moving the registering function to
the generic bearer layer, to the file bearer.c, and call it only once.
The same is true for the network device event notifier.
As a side effect, the two workqueues we are using for for setting up/
cleaning up media can now be eliminated. Furthermore, the array for
storing the specific media type structs, media_array[], can be entirely
deleted.
Note that the eth_started and ib_started flags were removed during the
code relocation. There is now only one call to bearer_setup and
bearer_cleanup, and these can logically not race against each other.
Despite its size, this cleanup work incurs no functional changes in TIPC.
In particular, it should be noted that the sequence ordering of received
packets is unaffected by this change, since packet reception never was
subject to any work queue handling in the first place.

tipc: remove TIPC usage of field af_packet_priv in struct net_device
TIPC is currently using the field 'af_packet_priv' in struct net_device
as a handle to find the bearer instance associated to the given network
device. But, by doing so it is blocking other networking cleanups, such
as the one discussed here:
http://patchwork.ozlabs.org/patch/178044/
This commit removes this usage from TIPC. Instead, we introduce a new
field, 'tipc_ptr', to the net_device structure, to serve this purpose.
When TIPC bearer is enabled, the bearer object is associated to
'tipc_ptr'. When a TIPC packet arrives in the recv_msg() upcall
from a networking device, the bearer object can now be obtained from
'tipc_ptr'. When a bearer is disabled, the bearer object is detached
from its underlying network device by setting 'tipc_ptr' to NULL.
Additionally, an RCU lock is used to protect the new pointer.
Henceforth, the existing tipc_net_lock is used in write mode to
serialize write accesses to this pointer, while the new RCU lock is
applied on the read side to ensure that the pointer is 100% valid
within its wrapped area for all readers.

Communication media types are abstracted through the struct 'tipc_media',
one per media type. These structs are allocated statically inside their
respective media file.
Furthermore, in order to be able to reach all instances from a central
location, we keep a static array with pointers to these structs. This
array is currently initialized at runtime, under protection of
tipc_net_lock. However, since the contents of the array itself never
changes after initialization, we can just as well initialize it at
compile time and make it 'const', at the same time making it obvious
that no lock protection is needed here.

This patch makes socketpair() use error paths which do not
rely on heavy-weight call to sys_close(): it's better to try
to push the file descriptor to userspace before installing
the socket file to the file descriptor, so that errors are
catched earlier and being easier to handle.
Using sys_close() seems to be the exception, while writing the
file descriptor before installing it look like it's more or less
the norm: eg. except for code used in init/, error handling
involve fput() and put_unused_fd(), but not sys_close().
This make socketpair() usage of sys_close() quite unusual.
So it deserves to be replaced by the common pattern relying on
fput() and put_unused_fd() just like, for example, the one used
in pipe(2) or recvmsg(2).
Three distinct error paths are still needed since calling
fput() on file structure returned by sock_alloc_file() will
implicitly call sock_release() on the associated socket
structure.

====================
Intel Wired LAN Driver Updates
This series contains updates to i40e, igb, ixgbe and ixgbevf.
Shannon provides a couple of i40e patches, first restricts the ethtool
diag test messages by using netif_info() macro to when the hardware
bit is enabled in the message level netdev message mask. Second
provides a fix for when there is an out-of-range descriptor request.
Kamil provides a fix for i40e by updating the loopback enum types and
add information about the current loopback mode to data returned from
get_link_info().
Jesse provides a fix for i40e define name that was being mis-used.
I40E_ITR_NONE was being used as an ITRN register index by accident
because it was easily associated with the i40e Rx ITR and friends
defines, when it should be associated with the DYN_CTL register sets.
Jacob provides an update for ixgbevf Kconfig description since the VF
driver supports more than just the 82599 device.
Don and Alex provide a cleanup patch for ixgbe to make it where head,
tail, next to clean and next to use are all reset in a single function
for both Tx and Rx path. Before, the code for this was spread out over
several areas which made it difficult to track what the values were for
each of the values.
Carolyn provides two igb patches to add a media switching feature for
i354 PHY's and new Media Auto Sense for 82580 devices only.
Aaron Sierra provides a fix for igb to resolve an issue with the 64-bit
PCI addresses being truncated because the return values of
pci_resource_start() and pci_resouce_end() were being cast to unsigned
long.
Guenter Roeck provides two igb patches, first simplifies the code by
attaching the hwmon sysfs attributes to hwmon device instead of the
PCI device. Second fixes the temperature sensor attribute index by
setting it to 1 instead of 0 (per hwmon ABI).
