Intel Wired LAN Driver Updates 2014-09-04
This series contains updates to i40e, i40evf, ixgbe and ixgbevf.
Catherine adds dual speed module support to i40e. Updates i40e to allow
the user to change link settings when the link is down.
Serey renames i40e_ndo_set_vf_spoofck() to i40e_ndo_set_vf_spookchk()
to be more consistent with what is defined in netdev and removes a
unnecessary variable assignment.
Jesse makes a malicious driver detection warning only print if extended
driver string is enabled for i40e. Fixes a panic under traffic load when
resetting or if/whenever there was a Tx-timeout because we were enabling
the Tx queue to early.
Anjali fixes an issue when PF reset fails, where we were trying to restart
the admin queue which has not been setup at that point. This resolves an
occasional kernel panic when PF reset fails for some reason.
Ethan Zhao replaces the use of a local i40e_vfs_are_assigned() with the
global kernel pci_vfs_assigned() for i40e.
Alex cleans up the FDB handling for ixgbe. This change makes it so that
the behavior for FDB handling is consistent between both the SR-IOV and
non-SR-IOV cases. The main change is that we perform bounds checking on
the number of SR-IOV addresses regardless of if SR-IOV is enabled or not
as we can only support a certain number of addresses in the hardware.
Emil extends the pending Tx work check to the VF interfaces, where the
driver initiates a reset of the interface on link loss with pending Tx
work in order to clear the rings. Introduces a delay for 82599 VFs of
at least 500 usecs to make sure the VFLINKS value is correct, since this
bit tends to flap when a DA or SFP+ cable is disconnected.
Jacob adds code comments in ixgbe to make it more obvious that we are
resetting features based on the fact that we do not have MSI-X enabled,
and cannot use the previous settings. Also resolves a kernel NULL
pointer dereference by limiting the combined total of MACVLAN and
SR-IOV VFs, since the hardware has a limited number of pools available
(64). Previously, no checks were in place to limit the number of
accelerated MACVLAN devices based on the number of pools, which would
be ok since there was already a limit for these well below the number of
available pools. However, SR-IOV uses the very same pools, therefore
we need to ensure that the total number of pools does not exceed the
number of pools available in the hardware.
v2:
- clean up code comment in patch 5 by replacing "an" with "auto
negotiation" based on feedback from Sergei Shtylyov
- removed un-necessary parenthesis around function call in patch 8
based on feedback from Sergei Shtylyov
====================
Simplify the interrupt resource lookup code in cpsw_probe() by the
following:
* Only look at the first member of the resource. As the driver only
works for DT-enabled platforms anyway, a resource of type
IORESOURCE_IRQ will only contain one single entry
(res->start == res->end), so there is no need for the iteration.
* Add a bounds check to avoid overflows if we are passed more than
ARRAY_SIZE(priv->irqs_table) resources.
* Assign 'ret' with the return value of devm_request_irq() so that
cpsw_probe() returns the appropriate error code.
* If devm_request_irq() fails, report the error code in the log
message.

The timestamping API has separate bits for generating and reporting
timestamps. A software timestamp should only be reported for a packet
when the packet has the relevant generation flag (SKBTX_..) set
and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set.
The second check was accidentally removed. Reinstitute the original
behavior.
Tested:
Without this patch, Documentation/networking/txtimestamp reports
timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set.
After the patch, it only reports them when the flag is set.

enic: Add support for rx_copybreak
The following series implements rx_copybreak.
dma_map_single()/dma_unmap_single() is more expensive than alloc_skb & memcpy
for smaller packets. By doing this we can reuse the dma buff which is already
mapped. This is very useful when iommu is on. The default skb copybreak value
is 256.
When iommu is on, we can go much higher than 256. All the drivers that supports
rx_copybreak provides module parameter to change this value. Since module
parameter is the least preferred way for changing driver values, this series
adds ethtool support for setting rx_copybreak.
v4:
Validate tunable length in ethtool_get_tunable, not in driver implemented
function.
Loose tunable_ops array for each tunable type. Define one function and let the
driver use switch case for each type.
Use double underscore for data type in UAPI headers.
Use const qualifier where possible.
v3:
Add tunable namespace to ethtool. Use new ethtool cmd ETHTOOL_S/GTUNABLE to
set/get rx_copybreak from userspace.
v2:
Add new ethtool_cmd for DMA buffer parameters, instead of adding new members to
existing ethtool_ringparam.

Defines enic_get_tunable() & enic_set_tunable() to get/set rx_copybreak.
As of now, these two function supports only rx_copybreak.

This patch adds new ethtool cmd, ETHTOOL_GTUNABLE & ETHTOOL_STUNABLE for getting
tunable values from driver.
Add get_tunable and set_tunable to ethtool_ops. Driver implements these
functions for getting/setting tunable value.

Marcel reported to see the following message when autoloading
is being triggered when adding nlmon device:
Loading kernel module for a network device with
CAP_SYS_MODULE (deprecated). Use CAP_NET_ADMIN and alias
netdev-nlmon instead.
This false-positive happens despite with having correct
capabilities set, e.g. through issuing `ip link del dev nlmon`
more than once on a valid device with name nlmon, but Marcel
has also seen it on creation time when no nlmon module is
previously compiled-in or loaded as module and the device
name equals a link type name (e.g. nlmon, vxlan, team).
Stephen says:
The netdev module alias is a hold over from the past. For
normal devices, people used to create a alias eth0 to and
point it to the type of network device used, that was back
in the bad old ISA days before real discovery.
Also, the tunnels create module alias for the control device
and ip used to use this to autoload the tunnel device.
The message is bogus and should just be removed, I also see
it in a couple of other cases where tap devices are renamed
for other usese.
As mentioned in 8909c9ad8f ("net: don't allow CAP_NET_ADMIN
to load non-netdev kernel modules"), we nevertheless still
might want to leave the old autoloading behaviour in place
as it could break old scripts, so for now, lets just remove
the log message as Stephen suggests.

With eBPF getting more extended and exposure to user space is on it's way,
hardening the memory range the interpreter uses to steer its command flow
seems appropriate. This patch moves the to be interpreted bytecode to
read-only pages.
In case we execute a corrupted BPF interpreter image for some reason e.g.
caused by an attacker which got past a verifier stage, it would not only
provide arbitrary read/write memory access but arbitrary function calls
as well. After setting up the BPF interpreter image, its contents do not
change until destruction time, thus we can setup the image on immutable
made pages in order to mitigate modifications to that code. The idea
is derived from commit 314beb9bca ("x86: bpf_jit_comp: secure bpf jit
against spraying attacks").
This is possible because bpf_prog is not part of sk_filter anymore.
After setup bpf_prog cannot be altered during its life-time. This prevents
any modifications to the entire bpf_prog structure (incl. function/JIT
image pointer).
Every eBPF program (including classic BPF that are migrated) have to call
bpf_prog_select_runtime() to select either interpreter or a JIT image
as a last setup step, and they all are being freed via bpf_prog_free(),
including non-JIT. Therefore, we can easily integrate this into the
eBPF life-time, plus since we directly allocate a bpf_prog, we have no
performance penalty.
Tested with seccomp and test_bpf testsuite in JIT/non-JIT mode and manual
inspection of kernel_page_tables. Brad Spengler proposed the same idea
via Twitter during development of this patch.

According to the IMX6 reference manuals, REF_SSP_EN (Reference clock enable
for SS function) must remain deasserted until the reference clock is
running at the appropriate frequency.
Delay enabling the reference clock for the SS function until it has
stabilized. This prevents a high link failure rate (>5%) on certain IMX6
boards at various temperatures.

The defined mechanism for programming the Tegra pinmux is to perform all
of the following at once in order, before using any I/O controller that
is affected by the pinmux:
- Set the CLAMP_INPUTS_WHEN_TRISTATED PMC register bit.
- Set up any GPIO pins to their "initial" state.
- Program all pinmux settings in one go.
Other methods such as:
- Not setting CLAMP_INPUTS_WHEN_TRISTATED.
- Not setting GPIOs to their "initial" state before programming the
pinmux settings of the related pin, in particular the mux function.
- Not programming the entire pinmux at once, in order to avoid
possible conflicting settings.
... are not qualified or supported by NVIDIA ASIC/syseng. They could
cause glitches or undesired output levels on some pins, or controller
malfunction.
While we've been getting away with doing something different on many
Tegra boards without issue, I believe we've just been getting lucky.
I'd like to switch all Tegra124 systems to the correct scheme now so
they provide the right example to follow, and require that any new
boards we support upstream work in the same fashion.
While it would be nice to update boards containing older SoCs for
consistency, I don't anticipate doing so. It's too much churn to change
at this time. At least with all Tegra124 boards converted, the most
recent boards provide the correct example.
Since the bootloader needs to reprogram the pinmux to access certain
peripherals, it must program the entire pinmux due to the supported
rules above. As such, there is no need to program any part of the pinmux
from the kernel, unless dynamic pinmuxing is used. Given this, we couuld
simply remove the pinmux "default" state from the DT entirely. However,
some bootloaders parse the DT to perform their initial pinmux setup, so
it's useful to keep the pinmux data in DT. To allow this while avoiding
redundant work in the kernel, rename the "default" state to "boot". The
kernel won't apply this, but bootloaders can still look for this state
name and apply it. Note however that the DT provides zero information
about the required initial GPIO setup, so bootloaders using this approach
are not likely to operate correctly without an additional GPIO
initialization table somewhere. Previous discussions on the DT mailing
list have rejected adding such a table to DT...
The following U-Boot commits fully initialize the pinmux:
Jetson TK1: 4ff213b8e478 ARM: tegra: clamp inputs on Jetson TK1
Venice2: 3365479ce78a ARM: tegra: Venice2 pinmux spreadsheet updates
Both are part of U-Boot v2014.07 and later.
Without those commits, the only fallout I see from this change is that
HDMI on Venice2 no longer works. Given the very small user-base of this
platform, I feel that requiring a bootloader update is reasonable.

The Acer Chromebook 13, codenamed Big, contains an NVIDIA tegra124
processor and is similar to the Venice2 reference platform.
The keyboard, USB 2, audio, sdcard and emmc have been tested
and work on the 1366x768 models. The Full HD models haven't been
tested yet.
WiFi does not yet work, it needs at least some PMIC changes to enable
the 32k clock.
The elan trackpad is not yet functional but hopefully will be soon as
there are patches under review.
There is also an issue on reboot because the TPM isn't reset. It will
cause the stock firmware to enter recovery mode. This can be worked
around by an EC-reset, press the refresh and power keys at the same
time.

These are related to how the early_tx hrtimer is set up, and it turns
