Ira W. Snyder 3b5c6b9e49 can: janz-ican3: add support for one shot mode
The Janz VMOD-ICAN3 hardware has support for one shot packet
transmission. This means that a packet will be attempted to be sent
once, with no automatic retries.

The SocketCAN core has a controller-wide setting for this mode:
CAN_CTRLMODE_ONE_SHOT. The Janz VMOD-ICAN3 hardware supports this flag
on a per-packet level, but the SocketCAN core does not.

Ira W. Snyder 30df5888e4 can: janz-ican3: avoid firmware lockup caused by infinite bus error quota
If the bus error quota is set to infinite and the host CPU cannot keep
up, the Janz VMOD-ICAN3 firmware will stop responding to control
messages until the controller is reset.

The firmware will automatically stop sending bus error messages when the
quota is reached, and will only resume sending bus error messages when
the quota is re-set to a positive value.

This limitation is worked around by setting the bus error quota to one
message, and then re-setting the quota to one message every time a bus
error message is received. By doing this, the firmware never stops
responding to control messages. The CAN bus can be reset without a
hard-reset of the controller card.

Ira W. Snyder 83702f6927 can: janz-ican3: fix support for CAN_RAW_RECV_OWN_MSGS
The Janz VMOD-ICAN3 firmware does not support any sort of TX-done
notification or interrupt. The driver previously used the hardware
loopback to attempt to work around this deficiency, but this caused all
sockets to receive all messages, even if CAN_RAW_RECV_OWN_MSGS is off.

Using the new function ican3_cmp_echo_skb(), we can drop the loopback
messages and return the original skbs. This fixes the issues with
CAN_RAW_RECV_OWN_MSGS.

A private skb queue is used to store the echo skbs. This avoids the need
for any index management.

Due to a lack of TX-error interrupts, bus errors are permanently
enabled, and are used as a TX-error notification. This is used to drop
an echo skb when transmission fails. Bus error packets are not generated
if the user has not enabled bus error reporting.

Ira W. Snyder 88b587039c can: janz-ican3: fix error and byte counters
The error and byte counter statistics were being incremented
incorrectly. For example, a TX error would be counted both in tx_errors
and rx_errors.

This corrects the problem so that tx_errors and rx_errors are only
incremented for errors caused by packets sent to the bus. Error packets
generated by the driver are not counted.

The byte counters are only increased for packets which are actually
transmitted or received from the bus. Error packets generated by the
driver are not counted.

Steffen Trumtrar 3d42a379b6 can: flexcan: add 2nd clock to support imx53 and newer
This patch adds support for a second clock to the flexcan driver. On
modern freescale ARM cores like the imx53 and imx6q two clocks ("ipg"
and "per") must be enabled in order to access the CAN core.

In the original driver, the clock was requested without specifying the
connection id, further all mainline ARM archs with flexcan support
(imx28, imx25, imx35) register their flexcan clock without a
connection id, too.

This patch first renames the existing clk variable to clk_ipg and
converts it to devm for easier error handling. The connection id "ipg"
is added to the devm_clk_get() call. Then a second clock "per" is
requested. As all archs don't specify a connection id, both clk_get
return the same clock. This ensures compatibility to existing flexcan
support and adds support for imx53 at the same time.

After this patch hits mainline, the archs may give their existing
flexcan clock the "ipg" connection id and implement a dummy "per"
clock.

This patch has been tested on imx28 (unmodified clk tree) and on imx53
with a seperate "ipg" and "per" clock.

Thadeu Lima de Souza Cascardo 4cce66cdd1 mlx4_en: map entire pages to increase throughput
In its receive path, mlx4_en driver maps each page chunk that it pushes
to the hardware and unmaps it when pushing it up the stack. This limits
throughput to about 3Gbps on a Power7 8-core machine.

One solution is to map the entire allocated page at once. However, this
requires that we keep track of every page fragment we give to a
descriptor. We also need to work with the discipline that all fragments will
be released (in the sense that it will not be reused by the driver
anymore) in the order they are allocated to the driver.

This requires that we don't reuse any fragments, every single one of
them must be reallocated. We do that by releasing all the fragments that
are processed and only after finished processing the descriptors, we
start the refill.

We also must somehow guarantee that we either refill all fragments in a
descriptor or none at all, without resorting to giving up a page
fragment that we would have already given. Otherwise, we would break the
discipline of only releasing the fragments in the order they were
allocated.

This has passed page allocation fault injections (restricted to the
driver by using required-start and required-end) and device hotplug
while 16 TCP streams were able to deliver more than 9Gbps.

Bjørn Mork 8b0d2f9ed3 net: e100: ucode is optional in some cases
commit 9ac32e1b firmware: convert e100 driver to request_firmware()

did a straight conversion of the in-driver ucode to external
files.  This introduced the possibility of the driver failing
to enable an interface due to missing ucode. There was no
evaluation of the importance of the ucode at the time.

Based on comments in earlier versions of this driver, and in
the source code for the FreeBSD fxp driver, we can assume that
the ucode implements the "CPU Cycle Saver" feature on supported
adapters.  Although generally wanted, this is an optional
feature. The ucode source is not available, preventing it from
being included in free distributions. This creates unnecessary
problems for the end users. Doing a network install based on a
free distribution installer requires the user to download and
insert the ucode into the installer.

Making the ucode optional when possible improves the user
experience and driver usability.

The ucode for some adapters include a bugfix, making it
essential.  We continue to fail for these adapters unless the
ucode is available.

Christian Riesch ceb02c91dd asix: Rework reading from EEPROM
The current code for reading the EEPROM via ethtool in the asix
driver has a few issues. It cannot handle odd length values
(accesses must be aligned at 16 bit boundaries) and interprets the
offset provided by ethtool as 16 bit word offset instead as byte offset.

modeled after the code in
drivers/net/ethernet/atheros/atl1e/atl1e_ethtool.c
and provides read access to the entire EEPROM with arbitrary
offsets and lengths.

Amir Vadai 1eb8c695bd net/mlx4_en: Add accelerated RFS support
Use RFS infrastructure and flow steering in HW to keep CPU
affinity of rx interrupts and application per TCP stream.

A flow steering filter is added to the HW whenever the RFS
ndo callback is invoked by core networking code.

Because the invocation takes place in interrupt context, the
actual setup of HW is done using workqueue. Whenever new filter
is added, the driver checks for expiry of existing filters.

Since there's window in time between the point where the core
RFS code invoked the ndo callback, to the point where the HW
is configured from the workqueue context, the 2nd, 3rd etc
packets from that stream will cause the net core to invoke
the callback again and again.

To prevent inefficient/double configuration of the HW, the filters
are kept in a database which is indexed using hash function to enable
fast access.

NeilBrown a05b7ea03d md: avoid crash when stopping md array races with closing other open fds.
md will refuse to stop an array if any other fd (or mounted fs) is
using it.
When any fs is unmounted of when the last open fd is closed all
pending IO will be flushed (e.g. sync_blockdev call in __blkdev_put)
so there will be no pending IO to worry about when the array is
stopped.

However in order to send the STOP_ARRAY ioctl to stop the array one
must first get and open fd on the block device.
If some fd is being used to write to the block device and it is closed
after mdadm open the block device, but before mdadm issues the
STOP_ARRAY ioctl, then there will be no last-close on the md device so
__blkdev_put will not call sync_blockdev.

If this happens, then IO can still be in-flight while md tears down
the array and bad things can happen (use-after-free and subsequent
havoc).

So in the case where do_md_stop is being called from an open file
descriptor, call sync_block after taking the mutex to ensure there
will be no new openers.

This is needed when setting a read-write device to read-only too.

NeilBrown 25f7fd470b md: fix bug in handling of new_data_offset
commit c6563a8c38
    md: add possibility to change data-offset for devices.

introduced a 'new_data_offset' attribute which should normally
be the same as 'data_offset', but can be explicitly set to a different
value to allow a reshape operation to move the data.

Unfortunately when the 'data_offset' is explicitly set through
sysfs, the new_data_offset is not also set, so the two would become
out-of-sync incorrectly.

One result of this is that trying to set the 'size' after the
'data_offset' would fail because it is not permitted to set the size
when the 'data_offset' and 'new_data_offset' are different - as that
can be confusing.
Consequently when mdadm tried to do this while assembling an IMSM
array it would fail.

This bug was introduced in 3.5-rc1.

Linus Torvalds eea03c20ae Make wait_for_device_probe() also do scsi_complete_async_scans()
Commit a7a20d1039 ("sd: limit the scope of the async probe domain")
make the SCSI device probing run device discovery in it's own async
domain.

However, as a result, the partition detection was no longer synchronized
by async_synchronize_full() (which, despite the name, only synchronizes
the global async space, not all of them).  Which in turn meant that
"wait_for_device_probe()" would not wait for the SCSI partitions to be
parsed.

And "wait_for_device_probe()" was what the boot time init code relied on
for mounting the root filesystem.

Now, most people never noticed this, because not only is it
timing-dependent, but modern distributions all use initrd.  So the root
filesystem isn't actually on a disk at all.  And then before they
actually mount the final disk filesystem, they will have loaded the
scsi-wait-scan module, which not only does the expected
wait_for_device_probe(), but also does scsi_complete_async_scans().

[ Side note: scsi_complete_async_scans() had also been partially broken,
  but that was fixed in commit 43a8d39d01 ("fix async probe
  regression"), so that same commit a7a20d1039 had actually broken
  setups even if you used scsi-wait-scan explicitly ]

Solve this problem by just moving the scsi_complete_async_scans() call
into wait_for_device_probe().  Everybody who wants to wait for device
probing to finish really wants the SCSI probing to complete, so there's
no reason not to do this.

So now "wait_for_device_probe()" really does what the name implies, and
properly waits for device probing to finish.  This also removes the now
unnecessary extra calls to scsi_complete_async_scans().

Alexander Duyck a16a0d2fb8 ixgbe: Cleanup holes in flags after removing several of them
This change is just meant to defragment the flags as there are several hole

Alexander Duyck fbe7ca7f9b ixgbe: Retire RSS enabled and capable flags
All of our hardware supports RSS even if it is only for a single queue.  So
instead of toting around the RSS enable flag I am updating the code so that
all devices are enabled and if we want to disable RSS it is indicated via
the RSS mask.

Alexander Duyck 73079ea041 ixgbe: Add support for SR-IOV w/ DCB or RSS
This change essentially makes it so that we can enable almost all of the
features all at once.  This patch allows for the combination of SR-IOV,
DCB, and FCoE in the case of the x540.  It also beefs up the SR-IOV by
adding support for RSS to the PF.

The testing matrix gets to be very complex for this patch as there are a
number of different features and subsets for queueing options.  I tried to
narrow these down a bit by restricting the PF to only supporting 4TC DCB
when it is enabled in addition to SR-IOV.

Alexander Duyck 435b19f621 ixgbe: Update configure virtualization to allow for multiple PF pools
This change allows all pools from the default pool forward to be enabled vi
ixgbe_configure_virtualization.  This is needed as we are planning to use
queues belonging to adjacent pools for FCoE when SR-IOV and FCoE are both
enabled.

In addition this patch contains some minor formatting changes as there were
a few spots that seemed to be in need of some cleanup.

Alexander Duyck eb022d058f ixgbevf: Fix multiple issues in ixgbevf_get/set_ringparam
In ixgbevf_get_ringparam we could run into a NULL pointer dereference
if the rings were not allocated when we attempted the call.  To prevent
that we can just access the tx/rx_ring_count values instead of attempting
to access the rings to get the count.

This change corrects a memory leak and memory corruption in
ixgbevf_set_ringparam.

The memory leak was due to us not freeing the resources from the ring
before overwriting them.  This change corrects the memory leak by making
certain to call ixgbe_free_tx/rx_resources on the rings prior to freeing
them.

The memory corruption was because we were replacing the rings but not
updating the q_vectors.  It addresses the memory corruption by leaving the
rings in place and instead just copying the contents of the new rings into
the existing rings.

Pascal Bouchareine 5d9a533bac ixgbevf: fix VF untagging when 802.1 prio is set
We have had an issue when using ixgbe+ixgbevf and 802.1 VLAN tagging.

When attaching a VLAN to a VF, frames with a 802.1q priority appeared
untagged on the VF hence not reaching the VLAN, where frames with
priority 0 where tagged as expected and seen by the VLAN device.

This seems due to the way ixgbevf is looking up the full tag
(prio+cfi+vlan) against the adapter active_vlans, as a condition to mark
the skb tagged.

Cloned patch of Eric Dumazet for bonding.

Some workloads greatly benefit of IFF_XMIT_DST_RELEASE capability
on output net device, avoiding dirtying dst refcount.

team currently disables IFF_XMIT_DST_RELEASE unconditionally.

If all ports have the IFF_XMIT_DST_RELEASE bit set, then
team dev can also have it in its priv_flags.

The VIDIOC_DV_TIMINGS_CAP ioctl check wasn't added to determine_valid_ioctls().
This caused this ioctl to always return -ENOTTY.

The cause for this was that for 3.5 two patch series were merged, one
changing V4L2 core ioctl handling and one adding new functionality, and
some of the new functionality wasn't handled by the new V4L2 core code.

Linus Torvalds fe2e27bb92 ARM: SoC fixes for SPEAr
These are arriving very late in the release cycle, but there has been
 a change of maintainers on the SPEAr platform and they have needed a
 while to get going.
 
 The patch count is higher than I would like at this point, but they're
 all relevant fixes and well-contained in their own platform code. I still
 think it's suitable 3.5 material and I don't think it should increase
 the need for a -rc8 since they are so contained.
