====================
Intel Wired LAN Driver Updates 2017-09-05
This series contains fixes for i40e only.
These two patches fix an issue where our nvmupdate tool does not work on RHEL 7.4
and newer kernels, in fact, the use of the nvmupdate tool on newer kernels can
cause the cards to be non-functional unless these patches are applied.
Anjali reworks the locking around accessing the NVM so that NVM acquire timeouts
do not occur which was causing the failed firmware updates.
Jake correctly updates the wb_desc when reading the NVM through the AdminQ.

When a test process is not able to write to TH_LOG_STREAM, this step
mechanism enable to print the assert number which triggered the failure.
This can be enabled by setting _metadata->no_print to true at the
beginning of the test sequence.
Update the seccomp-bpf test to return 0 if a test succeeded.
This feature is needed for the Landlock tests.

X722 devices use the AdminQ to access the NVM, and this requires taking
the AdminQ lock. Because of this, we lock the AdminQ during
i40e_read_nvm(), which is also called in places where the lock is
already held, such as the firmware update path which wants to lock once
and then unlock when finished after performing several tasks.
Although this should have only affected X722 devices, commit
96a39aed25e6 ("i40e: Acquire NVM lock before reads on all devices",
2016-12-02) added locking for all NVM reads, regardless of device
family.
This resulted in us accidentally causing NVM acquire timeouts on all
devices, causing failed firmware updates which left the eeprom in
a corrupt state.
Create unsafe non-locked variants of i40e_read_nvm_word and
i40e_read_nvm_buffer, __i40e_read_nvm_word and __i40e_read_nvm_buffer
respectively. These variants will not take the NVM lock and are expected
to only be called in places where the NVM lock is already held if
needed.
Since the only caller of i40e_read_nvm_buffer() was in such a path,
remove it entirely in favor of the unsafe version. If necessary we can
always add it back in the future.
Additionally, we now need to hold the NVM lock in i40e_validate_checksum
because the call to i40e_calc_nvm_checksum now assumes that the NVM lock
is held. We can further move the call to read I40E_SR_SW_CHECKSUM_WORD
up a bit so that we do not need to acquire the NVM lock twice.
This should resolve firmware updates and also fix potential raise that
could have caused the driver to report an invalid NVM checksum upon
driver load.

We check tx avail through vhost_enable_notify() in the past which is
wrong since it only checks whether or not guest has filled more
available buffer since last avail idx synchronization which was just
done by vhost_vq_avail_empty() before. What we really want is checking
pending buffers in the avail ring. Fix this by calling
vhost_vq_avail_empty() instead.
This issue could be noticed by doing netperf TCP_RR benchmark as
client from guest (but not host). With this fix, TCP_RR from guest to
localhost restores from 1375.91 trans per sec to 55235.28 trans per
sec on my laptop (Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz).

2) Get device_node from it
Since it is two distinct purpose, this patch add a parameter mdio_mux
that is linked to task 2.
This will also permit to register an of_node mdio-mux that lacks a direct

When an RxRPC service packet comes in, the target connection is looked up
by an rb-tree search under RCU and a read-locked seqlock; the seqlock retry
check is, however, currently skipped if we got a match, but probably
shouldn't be in case the connection we found gets replaced whilst we're
doing a search.
Make the lookup procedure always go through need_seqretry(), even if the
lookup was successful. This makes sure we always pick up on a write-lock
event.
On the other hand, since we don't take a ref on the object, but rely on RCU
to prevent its destruction after dropping the seqlock, I'm not sure this is
necessary.

The wrong register is checked for the Tx flow control bit,
it should have been maccfg1 not maccfg2.
This went unnoticed for so long probably because the impact is
hardly visible, not to mention the tangled code from adjust_link().
First, link flow control (i.e. handling of Rx/Tx link level pause frames)
is disabled by default (needs to be enabled via 'ethtool -A').
Secondly, maccfg2 always returns 0 for tx_flow_oldval (except for a few
old boards), which results in Tx flow control remaining always on
once activated.

Pull power management updates from Rafael Wysocki:
"This time (again) cpufreq gets the majority of changes which mostly

There also are some changes in the system suspend area, mostly related
to diagnostics and debug messages plus some renames of things related
to suspend-to-idle. One major change here is that suspend-to-idle is
now going to be preferred over S3 on systems where the ACPI tables
indicate to do so and provide requsite support (the Low Power Idle S0
_DSM in particular). The system sleep documentation and the tools
related to it are updated too.

DT bindings and update its whitelist of supported systems (Viresh
Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley

obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
- Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
Nguyen).
- Fix and clean up assorted issues in the cpufreq drivers and core
(Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
- Update the IO-wait boost handling in the schedutil governor to make
it less aggressive (Joel Fernandes).
- Rework system suspend diagnostics to make it print fewer messages
to the kernel log by default, add a sysfs knob to allow more
suspend-related messages to be printed and add Low Power S0 Idle
constraints checks to the ACPI suspend-to-idle code (Rafael
Wysocki, Srinivas Pandruvada).
- Prefer suspend-to-idle over S3 on ACPI-based systems with the
ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
interface present in the ACPI tables (Rafael Wysocki).
- Update documentation related to system sleep and rename a number of
items in the code to make it cleare that they are related to
suspend-to-idle (Rafael Wysocki).
- Export a variable allowing device drivers to check the target
system sleep state from the core system suspend code (Florian
Fainelli).
- Clean up the cpuidle subsystem to handle the polling state on x86
in a more straightforward way and to use %pOF instead of full_name
(Rafael Wysocki, Rob Herring).
- Update the devfreq framework to fix and clean up a few minor issues

- Extend diagnostics in the generic power domains (genpd) framework
and clean it up slightly (Thara Gopinath, Rob Herring).
- Fix and clean up a couple of issues in the operating performance

====================
net: dsa: Allow switch drivers to indicate number of TX queues
This patch series extracts the parts of the patch set that are likely not to be
controversial and actually bringing multi-queue support to DSA-created network
devices.
With these patches, we can now use sch_multiq as documented under
Documentation/networking/multique.txt and let applications dedice the switch
port output queue they want to use. Currently only Broadcom tags utilize that
information.
Resending based on David's feedback regarding the patches not in patchwork.
Changes in v2:
- use a proper define for the number of TX queues in bcm_sf2.c (Andrew)
Changes from RFC:
- dropped the ability to configure RX queues since we don't do anything with
those just yet
- dropped the patches that dealt with binding the DSA slave network devices
queues with their master network devices queues this will be worked on
separately.

Even though TC2QOS mapping is for switch egress queues, we need to
configure it correclty in order for the Broadcom tag ingress (CPU ->
switch) queue selection to work correctly since there is a 1:1 mapping
between switch egress queues and ingress queues.

The switch supports 8 egress queues per port, so indicate that such that
net/dsa/slave.c::dsa_slave_create can allocate the right number of TX queues.
While at it use SF2_NUM_EGRESS_QUEUE as a define for the number of queues we
support.

Let switch drivers indicate how many TX queues they support. Some
switches, such as Broadcom Starfighter 2 are designed with 8 egress
queues. Future changes will allow us to leverage the queue mapping and
direct the transmission towards a particular queue.

Pull GPIO updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v4.14 cycle.
Not so much changes this time, phew. David Daney and Bartosz
Golaszewski did all the really interesting work in infrastructure
improvement across GPIO and IRQ core, hats off for them and to tglx
and Marc Z for general help with these patch sets.
Core changes:
- Allow the GPIO irqchip to allocate IRQs dynamically. This is an
important change on systems where only a restricted number of IRQs,
lesser than the number of GPIO lines, can be utilized. Now we can
allocate these on a first-come-first-served basis instead of
hogging up valuable IRQ lines.
- Serious fix-up of the kerneldoc documentation and inclusion into
the kerneldoc builds.
- Pulled in the IRQ simulator from the IRQ core tree and use this in
the GPIO mockup driver for exhaustive testing of interrupt
abilities.
New drivers:
- New driver for ThunderX and OCTEON-TX. This is especially
interesting as it picks up improvements from the IRQ core that
allow us to handle fasteoi ACKs upwards in a hierarchy when there
are IRQ flag latches on several levels in a hierarchy. Very
interesting work here.
- New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
Misc:
- Several fixes and improvements for Xilinx Zynq GPIO.
- Support an enablement GPIO for the 74x164 GPIO.
- Switch a bunch of chips to use devres to allocate irq descriptors.
- A bunch of constification fixes"

flow_dissector: Flow dissector fixes
This patch set fixes some basic issues with __skb_flow_dissect function.
Items addressed:
- Cleanup control flow in the function; in particular eliminate a
bunch of goto's and implement a simplified control flow model
- Add limits for number of encapsulations and headers that can be
dissected
v2:
- Simplify the logic for limits on flow dissection. Just set the
limit based on the number of headers the flow dissector can
processes. The accounted headers includes encapsulation headers,
extension headers, or other shim headers.
Tested:
Ran normal traffic, GUE, and VXLAN traffic.

In flow dissector there are no limits to the number of nested
encapsulations or headers that might be dissected which makes for a
nice DOS attack. This patch sets a limit of the number of headers
that flow dissector will parse.
Headers includes network layer headers, transport layer headers, shim
headers for encapsulation, IPv6 extension headers, etc. The limit for
maximum number of headers to parse has be set to fifteen to account for
a reasonable number of encapsulations, extension headers, VLAN,
in a packet. Note that this limit does not supercede the STOP_AT_*
flags which may stop processing before the headers limit is reached.

__skb_flow_dissect is riddled with gotos that make discerning the flow,
debugging, and extending the capability difficult. This patch
reorganizes things so that we only perform goto's after the two main
switch statements (no gotos within the cases now). It also eliminates
several goto labels so that there are only two labels that can be target
for goto.
