tipc: add name distributor resiliency queue
TIPC name table updates are distributed asynchronously in a cluster,
entailing a risk of certain race conditions. E.g., if two nodes
simultaneously issue conflicting (overlapping) publications, this may
not be detected until both publications have reached a third node, in
which case one of the publications will be silently dropped on that
node. Hence, we end up with an inconsistent name table.
In most cases this conflict is just a temporary race, e.g., one
node is issuing a publication under the assumption that a previous,
conflicting, publication has already been withdrawn by the other node.
However, because of the (rtt related) distributed update delay, this
may not yet hold true on all nodes. The symptom of this failure is a
syslog message: "tipc: Cannot publish {%u,%u,%u}, overlap error".
In this commit we add a resiliency queue at the receiving end of
the name table distributor. When insertion of an arriving publication
fails, we retain it in this queue for a short amount of time, assuming
that another update will arrive very soon and clear the conflict. If so
happens, we insert the publication, otherwise we drop it.
The (configurable) retention value defaults to 2000 ms. Knowing from
experience that the situation described above is extremely rare, there
is no risk that the queue will accumulate any large number of items.

Merge branch 'xmit_list'
David Miller says:
====================
net: Make dev_hard_start_xmit() work fundamentally on lists
After this patch set, dev_hard_start_xmit() will work fundemantally on
any and all SKB lists.
This opens the path for a clean implementation of pulling multiple
packets out during qdisc_restart(), and then passing that blob in one
shot to dev_hard_start_xmit().
There were two main architectural blockers to this:
1) The GSO handling, we kept the original GSO head SKB around simply
because dev_hard_start_xmit() had no way to communicate to the
caller how far into the segmented list it was able to go. Now it
can, so the head GSO can be liberated immediately.
All of the special GSO head SKB destructor et al. handling goes
away too.
2) Validate of VLAN, CSUM, and segmentation characteristics was being
performed inside of dev_hard_start_xmit(). If want to truly batch,
we have to let the higher levels to this. In particular, this is
now dequeue_skb()'s job.
And with those two issues out of the way, it should now be trivial to
build experiments on top of this patch set, all of the framework
should be there now. You could do something as simple as:
skb = q->dequeue(q);
if (skb)
skb = validate_xmit_skb(skb, qdisc_dev(q));
if (skb) {
struct sk_buff *new, *head = skb;
int limit = 5;
do {
new = q->dequeue(q);
if (new)
new = validate_xmit_skb(new, qdisc_dev(q));
if (new) {
skb->next = new;
skb = new;
}
} while (new && --limit);
skb = head;
}
inside of the else branch of dequeue_skb().

====================
net: Checksum offload changes - Part VI
I am working on overhauling RX checksum offload. Goals of this effort
are:
- Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY
- Preserve CHECKSUM_COMPLETE through encapsulation layers
- Don't do skb_checksum more than once per packet
- Unify GRO and non-GRO csum verification as much as possible
- Unify the checksum functions (checksum_init)
- Simplify code
What is in this sixth patch set:
- Clarify the specific requirements of devices returning
CHECKSUM_UNNECESSARY (comments in skbuff.h).
- Add csum_level field to skbuff. This is used to express how
many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1).
- Change __skb_checksum_validate_needed to "consume" each checksum
as indicated by csum_level as layers of the the packet are parsed.
- Remove skb_pop_rcv_encapsulation, no longer needed in the new
csum_level model.
- Allow GRO path to "consume" checksums provided in CHECKSUM_UNNECESSARY
and to report new verfied checksums for use in normal path fallback.
- Add proper support to SCTP to accept CHECKSUM_UNNECESSARY to validate
header CRC.
- Modify drivers to set skb->csum_level instead of setting
skb->encapsulation to indicate validation of an encapsulated
checksum on receive.
v2:
Allocate a new 16 bits for flags in skbuff.
Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)

Intel Wired LAN Driver Updates 2014-08-27
This series contains updates to i40e and i40evf.
Carolyn provides two patches, first changes the wording of the flow
director add/remove and asynchronous failure messages to include the
fd_id to try and add some way to track the operations on a given fd_id.
Second adds a check during handle_link_event for unqualified modules
when link is down and there is a module plugged in.
Anjali provides four patches to i40e/i40evf. First update flow director
messages so that a user can tell if a filter was added or deleted. Then
updates the ATR policy to not auto-disable ATR when we have errors in
programming. The disabling of ATR when we got programming errors was
buggy and was still adding new rules and causing continuous errors.
With this policy change, we flush instead when we see too many errors.
In addition she adds a flow director flush counter to ethtool to help
know how many times the interface had to flush and replay the flow
director filter table. Updates the driver to ignores a driver
perceived transmit hang if the number of descriptors pending is less
than 4, and instead log a stat when this situation happens. This is
because the queue progresses forward and the stack never experiences
a real hang in these situations.
Shannon provides three patches for i40e/i40evf, first enables the
l2tsel bit on receive queue contexts that are assigned to VFs so that
the VF can get the stripped VLAN tag. Then adds a max buffer size
parameter to the print helper to be sure the code knows when to stop.
Lastly, remove the complaint when removing the default MAC VLAN filter.
This was because old firmware had an incorrect MAC VLAN filter that
needed to be replaced at startup, and now newer firmware does not have
this problem. So now we only add the new filter if the removal
succeeded and no need to complain if the removal fails.
Ashish provides a change to vsi->num_queue_pairs to equal the number
that is configured by the VF. This limits the number of queues that
are enabled/disabled and fixes the mismatch case for when a VF
configures fewer queues than is allocated to it by the PF.

dsa: Broadcom Starfighter 2 switch support
This patch series adds support for the Broadcom Starfighter 2 (Roboswitch
successor) using the existing DSA infrastructure. This integrated switch
is heavily used in Set Top Box, Cable gateways and DSL gateways products
from Broadcom, and to a larger extent the new ARM-based Wi-Fi routers although
slightly differently.
Changes in v5 are the introduction of ETH_P_XDSA as suggested by Alexander to
help capture applications see this is a multiplexed DSA approach now.
Changes in v4 are the introducing of an indirection level for DSA switch tag
protocols receive and transmit functions.
I intentionnaly did not address one comment from Alexander who suggested to
move port_names and port_dn in a separate structure since that involves
touching arch/arm/ and arch/blackfin/ code which I am not yet comfortable
doing.
Notable changes in v3 is the preliminary patch that reworks the skb->protocol
override helpers for non-Ethertype switch tags, based on feedback from
Alexander Duyck.
The biggest changes from v1 of this patch series are:
- use the new fixed PHY helpers
- improved the switch driver with more complete features (interrupts,
(RG)MII configuration, memory arrays power down/up, port disabling/enable
VLAN separation
Future work will focus on bringing the upstream driver in feature parity with
the current downstream driver, including:
- adding Wake-on-LAN support to the switch
- adding suspend/resume callbacks for S2/S3 Power Management modes
- extending the switch register interface to cover BCM5310X SoCs

net: dsa: reduce number of protocol hooks
DSA is currently registering one packet_type function per EtherType it
needs to intercept in the receive path of a DSA-enabled Ethernet device.
Right now we have three of them: trailer, DSA and eDSA, and there might
be more in the future, this will not scale to the addition of new
protocols.
This patch proceeds with adding a new layer of abstraction and two new
functions:
dsa_switch_rcv() which will dispatch into the tag-protocol specific
receive function implemented by net/dsa/tag_*.c
dsa_slave_xmit() which will dispatch into the tag-protocol specific
transmit function implemented by net/dsa/tag_*.c
When we do create the per-port slave network devices, we iterate over
the switch protocol to assign the DSA-specific receive and transmit
operations.
A new fake ethertype value is used: ETH_P_XDSA to illustrate the fact
that this is no longer going to look like ETH_P_DSA or ETH_P_TRAILER
like it used to be.
This allows us to greatly simplify the check in eth_type_trans() and
always override the skb->protocol with ETH_P_XDSA for Ethernet switches

operations, including returning to the HW default address. This simplifies
the code that was trying to be too smart.
Lastly, this pulls the hardware default mac address out into separate
handling code and keeps the broadcast filtering from getting munged.

i40e/i40evf: add max buf len to aq debug print helper
There is at least one case in the Firmware API where the response to a
command changes the buffer size field in the AQ descriptor to a larger
number than what the request's buffer size started as. This is in addition
to setting an error flag and is in order to tell the requester how much
larger a buffer is required for the answer. We need to be sure not to
use that number when dumping the contents of the data buffer because it
can send us into the weeds and generate an invalid pointer exception.
This patch adds a max buffer size parameter to the print helper to be
sure the code knows when to stop.

i40e: ATR policy change to flush the table to clean stale ATR rules
Instead of disabling ATR when we get a programming error, we now
will wait it out to see if some room gets created by ATR rule deletion.
If we still have too many errors and ATR filter count did not change
much, its time to flush and replay. We no more auto-disable ATR when
we have errors in programming.
The disabling of ATR when we get programming error was buggy and
was still adding new rules and causing continuous errors. With this
policy change we flush instead when we see too many errors.
ATR is still disabled if we add a SB rule for TCP/IPv4 flow type,
more logic is added to re-enable it once all SB TCP/IPv4 rules are gone.

team: set IFF_TEAM_PORT priv_flag after rx_handler is registered
When one tries to add eth as a port into team and that eth is already in
use by other rx_handler device (macvlan, bond, bridge, ...) a bug in
team_port_add() causes that IFF_TEAM_PORT flag is set before rx_handler
is registered. In between, netdev nofifier is called and
team_device_event() sees IFF_TEAM_PORT and thinks that rx_handler_data

Fix this by reordering rx_handler register and IFF_TEAM_PORT priv flag

This series contains mostly bug fixes, but never the less is intended
for `net-next' and not `net', as:
- Some of the fixes are quite insignificant [`VF clean statistics',
`ethtool -d might cause timeout in log'].
- Some only recently were submitted to `net-next' [`Fix timesync endianity'].
- Some are not usually compiled as part of the kernel [`Fix stop-on-error'].
Dave - please consider applying this series to `net-next'; If you prefer,
I can break this series into 2 parts [one for `net' and the other for
`net-next'] - but personally I don't see much benefit in it.
