lib/rhashtable: allow user to set the minimum shifts of shrinking
Although rhashtable library allows user to specify a quiet big size
for user's created hash table, the table may be shrunk to a
very small size - HASH_MIN_SIZE(4) after object is removed from
the table at the first time. Subsequently, even if the total amount
of objects saved in the table is quite lower than user's initial
setting in a long time, the hash table size is still dynamically
adjusted by rhashtable_shrink() or rhashtable_expand() each time
object is inserted or removed from the table. However, as
synchronize_rcu() has to be called when table is shrunk or
expanded by the two functions, we should permit user to set the
minimum table size through configuring the minimum number of shifts
according to user specific requirement, avoiding these expensive
actions of shrinking or expanding because of calling synchronize_rcu().

qdisc: validate frames going through the direct_xmit path
In commit
50cbe9ab5f8d ("net: Validate xmit SKBs right when we
pull them out of the qdisc") the validation code was moved out of
dev_hard_start_xmit and into dequeue_skb.
However this overlooked the fact that we do not always enqueue
the skb onto a qdisc. First situation is if qdisc have flag
TCQ_F_CAN_BYPASS and qdisc is empty. Second situation is if
there is no qdisc on the device, which is a common case for
software devices.
Originally spotted and inital patch by Alexander Duyck.
As a result Alex was seeing issues trying to connect to a
vhost_net interface after commit
50cbe9ab5f8d was applied.
Added a call to validate_xmit_skb() in __dev_xmit_skb(), in the
code path for qdiscs with TCQ_F_CAN_BYPASS flag, and in
__dev_queue_xmit() when no qdisc.
Also handle the error situation where dev_hard_start_xmit() could
return a skb list, and does not return dev_xmit_complete(rc) and
falls through to the kfree_skb(), in that situation it should
call kfree_skb_list().

sock: deduplicate errqueue dequeue
sk->sk_error_queue is dequeued in four locations. All share the
exact same logic. Deduplicate.
Also collapse the two critical sections for dequeue (at the top of
the recv handler) and signal (at the bottom).
This moves signal generation for the next packet forward, which should
be harmless.
It also changes the behavior if the recv handler exits early with an
error. Previously, a signal for follow-up packets on the errqueue
would then not be scheduled. The new behavior, to always signal, is
arguably a bug fix.
For rxrpc, the change causes the same function to be called repeatedly
for each queued packet (because the recv handler == sk_error_report).
It is likely that all packets will fail for the same reason (e.g.,
memory exhaustion).
This code runs without sk_lock held, so it is not safe to trust that
sk->sk_err is immutable inbetween releasing q->lock and the subsequent
test. Introduce int err just to avoid this potential race.

====================
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 seventh patch set:
- Add skb->csum. This allows a device or GRO to indicate that an
invalid checksum was detected.
- Checksum unncessary to checksum complete conversions.
With these changes, I believe that the third goal of the overhaul is
now mostly achieved. In the case of no encapsulation or one layer of
encapsulation, there should only be at most one skb_checksum over
each packet (between GRO and normal path). In the case of two layers
of encapsulation, it is still possible with the right combination of
non-zero and zero UDP checksums to have >1 skb_checksum. For instance:
IP>GRE(with csum)>IP>UDP(zero csum)>VXLAN>IP>UDP(non-zero csum),
would likely necessiate an skb_checksum in GRO and normal path.
This doesn't seem like a common scenario at all so I'm inclined to
not address this now, if multiple layers of encapsulation becomes
popular we can reassess.
Note that checksum conversion shows a nice improvement for RX VXLAN when
outer UDP checksum is enabled (12.65% CPU compared to 20.94%). This
is not only from the fact that we don't need checksum calculation on
the host, but also allows GRO for VXLAN in this case. Checksum
conversion does not help send side (which still needs to perform
a checksum on host). For that we will implement remote checksum offload
in a later patch
(http://tools.ietf.org/html/draft-herbert-remotecsumoffload-00).
Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)

This flag indicates that an invalid checksum was detected in the

Checksums can be marked bad from a driver or the GRO path (the latter

CHECKSUM_NONE).
csum_bad works in conjunction with ip_summed value. In the case that

csum_level == 1, and csum_bad is set-- then the third checksum in the
packet is bad. In the normal path, the packet will be dropped when
processing the protocol layer of the bad checksum:
__skb_decr_checksum_unnecessary called twice for the good checksums

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
