^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
There is no bug here, but the code is not perfect either. It copies
sizeof(pkt_dev->/member/) - 1 from user space into buf, and then does
a strcmp(pkt_dev->/member/, buf) hence assuming buf will be null-terminated
and shorter than pkt_dev->/member/ (pkt_dev->/member/ is never
explicitly null-terminated, and strncpy() doesn't have to null-terminate
so the assumption must be on buf). The use of strncpy() without explicit
null-termination looks suspicious. Convert to use straight strcpy().
strncpy() would also null-pad the output, but that's clearly unnecessary
since the author calls memset(pkt_dev->/member/, 0, sizeof(..)); prior
to strncpy(), anyway.
While at it format the code for "dst_min", "dst_max", "src_min" and
"src_max" in the same way by removing extra new lines in one case.

Commit
784abe24c903 ("net: Add decrypted field to skb")
introduced a 'decrypted' field that is explicitly copied on skb
copy and clone.
Move it between headers_start[0] and headers_end[0], so that we
don't need to copy it explicitly as it's copied by the memcpy()
in __copy_skb_header().
While at it, drop the assignment in __skb_clone(), it was
already redundant.
This doesn't change the size of sk_buff or cacheline boundaries.

will be again a 15-bits hole when this change is merged with

====================
mlxsw: Introduce initial Spectrum-2 support
This patch set adds initial support for the Spectrum-2 ASIC. The first
two patches add Spectrum-2 specific KVD linear (KVDL) manager. Unlike
the Spectrum ASIC, there is no linear memory and instead the type of the
entry (e.g., nexthop) and its index are hashed and the entry is placed
in the computed address in the hash-based KVD memory.
The third patch adds Spectrum-2 stubs in the multicast routing code.
Support for multicast routing will be added later on.
Patches 4-15 add ACL support. The Spectrum-2 ASIC includes an
algorithmic TCAM (A-TCAM) and a regular circuit TCAM (C-TCAM) for rules
that can't be inserted into the A-TCAM. This set does not make use of
the A-TCAM and only places rules in the C-TCAM. This provides equivalent
scale and performance to the Spectrum ASIC. A follow-up patch set will
introduce A-TCAM support.
The last patch extends the main driver file to work with both ASICs.

net: dsa: realtek-smi: Add Realtek SMI driver
This adds a driver core for the Realtek SMI chips and a
subdriver for the RTL8366RB. I just added this chip simply
because it is all I can test.
The code is a massaged variant of the code that has been
sitting out-of-tree in OpenWRT for years in the absence of
a proper switch subsystem. This creates a DSA driver for it.
I have tried to credit the original authors wherever
possible.
The main changes I've done from the OpenWRT code:
- Added an IRQ chip inside the RTL8366RB switch to demux and
handle the line state IRQs.
- Distributed the phy handling out to the PHY driver.
- Added some RTL8366RB code that was missing in the driver at
the time, such as setting up "green ethernet" with a funny
jam table and forcing MAC5 (the CPU port) into 1 GBit.
- Select jam table and add the default jam table from the
vendor driver, also for ASIC "version 0" if need be.
- Do not store jam tables in the device tree, store them
in the driver.
- Pick in the "initvals" jam tables from OpenWRT's driver
and make those get selected per compatible for the
whole system. It's apparently about electrical settings
for this system and whatnot, not really configuration
from device tree.
- Implemented LED control: beware of bugs because there are
no LEDs on the device I am using!
We do not implement custom DSA tags. This is explained in
a comment in the driver as well: this "tagging protocol" is
not simply a few extra bytes tagged on to the ethernet
frame as DSA is used to. Instead, enabling the CPU tags
will make the switch start talking Realtek RRCP internally.
For example a simple ping will make this kind of packets
appear inside the switch:
0000 ff ff ff ff ff ff bc ae c5 6b a8 3d 88 99 a2 00
0010 08 06 00 01 08 00 06 04 00 01 bc ae c5 6b a8 3d
0020 a9 fe 01 01 00 00 00 00 00 00 a9 fe 01 02 00 00
0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
As you can see a custom "8899" tagged packet using the
protocol 0xa2. Norm RRCP appears to always have this
protocol set to 0x01 according to OpenRRCP. You can also
see that this is not a ping packet at all, instead the
switch is starting to talk network management issues
with the CPU port.
So for now custom "tagging" is disabled.
This was tested on the D-Link DIR-685 with initramfs and
OpenWRT userspaces and works fine on all the LAN ports
(lan0 .. lan3). The WAN port is yet not working.

net: phy: sfp: Add HWMON support for module sensors
SFP modules can contain a number of sensors. The EEPROM also contains
recommended alarm and critical values for each sensor, and indications
of if these have been exceeded. Export this information via
HWMON. Currently temperature, VCC, bias current, transmit power, and
possibly receiver power is supported.
The sensors in the modules can either return calibrate or uncalibrated
values. Uncalibrated values need to be manipulated, using coefficients
provided in the SFP EEPROM. Uncalibrated receive power values require
floating point maths in order to calibrate them. Performing this in
the kernel is hard. So if the SFP module indicates it uses
uncalibrated values, RX power is not made available.
With this hwmon device, it is possible to view the sensor values using

curr1_min: 0.002
curr1_max: 0.010
curr1_lcrit: 0.000
curr1_crit: 0.011
curr1_min_alarm: 1.000
curr1_max_alarm: 0.000
curr1_lcrit_alarm: 1.000
curr1_crit_alarm: 0.000
In order to keep the I2C overhead to a minimum, the constant values,
such as limits and calibration coefficients are read once at module
insertion time. Thus only reading *_input and *_alarm properties
requires i2c read operations.

r8169: add phylib support
Now that all the basic refactoring has been done we can add phylib
support. This patch series was successfully tested on:
RTL8168h
RTL8168evl
RTL8169sb
Changes in v2:
- return error in mdio ops if phyaddr > 0
- advertise pause modes
- added reviewed-by for several patches
Changes in v3:
- return ENODEV for unused phy addresses in mdio ops
- remove unneeded PHY suspend in patch 2
- use recently added phy_speed_down and phy_speed_up in patch 7
- other minor changes based on review comments
