commit afaa3f65
(tipc: purge links when bearer is disabled) was an attempt to resolve
a problem that turned out to have a more profound reason.

When we disable a bearer, we delete all its pertaining links if
there is no other bearer to perform failover to, or if the module
is shutting down. In case there are dual bearers, we wait with
deleting links until the failover procedure is finished.

However, this misses the case when a link on the removed bearer
was already down, so that there will be no failover procedure to
finish the link delete. This causes confusion if a new bearer is
added to replace the removed one, and also entails a small memory
leak.

This commit takes the current state of the link into account when
deciding when to delete it, and also reverses the above-mentioned
commit.

If the inflate call failed it would return NULL.  As a result tp would be
set to NULL and cause use to trigger a NULL pointer dereference in
should_halve if the inflate failed on the first attempt.

In order to prevent this we should decrement max_work before we actually
attempt to inflate as this will force us to exit before attempting to halve
a node we should have inflated.  In order to keep things symmetric between
inflate and halve I went ahead and also moved the decrement of max_work for
the halve case as well so we take care of that before we actually attempt
to halve the tnode.

In the case of a trie that had no tnodes with a key of 0 the initial

This resulted in an entire trie being skipped.

In order resolve this I have updated the cindex logic in the initial

path.

1) Address link problems in the bridge code after e5de75bf. Fix it by

   dependency between bridge and br_netfilter.

2) Address sparse warnings in the netfilter reject code, patch from

in the following link problem:

Moreover it creates a hard dependency between br_netfilter and the
bridge core, which is what we've been trying to avoid so far.

Resolve this problem by using a hook structure so we reduce #ifdef
pollution and keep bridge netfilter specific code under br_netfilter.c
which was the original intention.

net: dsa: remove restriction on platform_device

This patch series removes the restriction in DSA to operate exclusively with
platform_device Ethernet MAC drivers when using Device Tree. This basically
allows arbitrary Ethernet MAC drivers to be used now in conjunction with
Device Tree.

The reason was that DSA was using a of_find_device_by_node() which limits
the device_node to device pointer search exclusively to platform_device,
in our case, we are interested in doing a "class" research and lookup the
net_device.

Thanks to Chris Packham for testing this on his platform.

Changes in v2:

- fix build for !CONFIG_OF_NET
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Using of_find_device_by_node() restricts the search to platform_device that
match the specified device_node pointer. This is not even remotely true for
network devices backed by a pci_device for instance.

of_find_net_device_by_node() allows us to do a more thorough lookup to find the
struct net_device corresponding to a particular device_node pointer.

For symetry with the non-OF code path, we hold the net_device pointer in
dsa_probe() just like what dev_to_net_dev() does when we call this
function.
Signed-off-by: NFlorian Fainelli <f.fainelli@gmail.com>
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add a helper function which allows getting the struct net_device pointer
associated with a given struct device_node pointer. This is useful for
instance for DSA Ethernet devices not backed by a platform_device, but a PCI
device.

Since we need to access net_class which is not accessible outside of
net/core/net-sysfs.c, this helper function is also added here and gated
with CONFIG_OF_NET.

Network devices initialized with SET_NETDEV_DEV() are also taken into
account by checking for dev->parent first and then falling back to
checking the device pointer within struct net_device.

  As well as with function tracing too.  Pratyush Anand first reported
  this issue to me and supplied a patch.  When I tested this on my x86
  test box, it caused thousands of backtraces and warnings to appear in

  workqueue: fix hang involving racing cancel[_delayed]_work_sync()'s for PREEMPT_NONE

In commit c637c103
("tipc: resolve race problem at unicast message reception") we
introduced a new mechanism for delivering buffers upwards from link
to socket layer.

That code contains a bug in how we handle the new link input queue
during failover. When a link is reset, some of its users may be blocked
because of congestion, and in order to resolve this, we add any pending
wakeup pseudo messages to the link's input queue, and deliver them to
the socket. This misses the case where the other, remaining link also
may have congested users. Currently, the owner node's reference to the
remaining link's input queue is unconditionally overwritten by the
reset link's input queue. This has the effect that wakeup events from
the remaining link may be unduely delayed (but not lost) for a
potentially long period.

We fix this by adding the pending events from the reset link to the
input queue that is currently referenced by the node, whichever one
it is.

When an interface is deleted from a net namespace the ifindex in the
corresponding entries in PF_PACKET sockets' mclists becomes stale.
This can create inconsistencies if later an interface with the same ifindex
is moved from a different namespace (not that unlikely since ifindexes are
per-namespace).
In particular we saw problems with dev->promiscuity, resulting
in "promiscuity touches roof, set promiscuity failed. promiscuity
feature of device might be broken" warnings and EOVERFLOW failures of
setsockopt(PACKET_ADD_MEMBERSHIP).
This patch deletes the mclist entries for interfaces that are deleted.
Since this now causes setsockopt(PACKET_DROP_MEMBERSHIP) to fail with
EADDRNOTAVAIL if called after the interface is deleted, also make
packet_mc_drop not fail.

Intel Wired LAN Driver Updates 2015-03-09

This series contains updates to i40e and i40evf.

Greg cleans up some "hello world" strings which were left around from
early development.

Shannon modifies the drive to make sure the sizeof() calls are taking
the size of the actual struct that we care about.  Also updates the
NVMUpdate read/write so that it is less noisy when logging.  This was
because the NVMUpdate tool does not necessarily know the ReadOnly map of
the current NVM image, and must try reading and writing words that may be
protected.  This generates an error out of the Firmware request that the
driver logs.  Unfortunately, this ended up spitting out hundreds of
bogus read/write error messages.  If a user wants the noisy logging,
the change can be overridden by enabling the NVM update debugging.

Mitch fixes a possible deadlock issue where if a reset occurred when the
netdev is closed, the reset task will hang in napi_disable.  Added
ethtool RSS support as suggested by Ben Hutchings.

Jesse fixes a bug introduced in the force writeback code, where the
interrupt rate was set to 0 (maximum) by accident.  The driver must
correctly set the NOITR fields to avoid IT update as a side effect
of triggering the software interrupt.

I provided a simple cleanup to make the use of PF/VF consistent, which
was reported by Joe Perches.

Commit 9bbb4ecc ("tipc: standardize recvmsg routine") changed
the sleep/wakeup behaviour for sockets entering recv() or accept().
In this process the order of reporting -EAGAIN/-EINTR was reversed.
This caused problems with wrong errno being reported back if the
timeout expires. The same problem happens if the socket is
nonblocking and recv()/accept() is called when the process have
pending signals. If there is no pending data read or connections to
accept, -EINTR will be returned instead of -EAGAIN.
