58a0228707 ACPI updates for 4.20-rc1
- Fix ACPICA issues related to the handling of module-level AML
    and make the ACPI initialization code parse ECDT before loading
    the definition block tables (Erik Schmauss).
 
  - Update ACPICA to upstream revision 20181003 including fixes
    related to the ill-defined "generic serial bus" and the handling
    of the _REG object (Bob Moore).

Pull LED updates from Jacek Anaszewski:
"We introduce LED pattern trigger - the idea that was proposed three
 years ago now received enough attention and determination to drive it
 to the successful end.

  There is also one new LED class driver and couple of improvements to
  the existing ones.

  New LED class driver:
   - add support for Panasonic AN30259A with related DT bindings

  New LED trigger:
   - introduce LED pattern trigger

  leds-sc27xx-bltc:
   - implement pattern_set/clear ops to enable support for pattern
     trigger's hw_pattern sysfs file

  Improvements to existing LED class drivers:
   - leds-pwm: don't print error message on -EPROBE_DEFER
   - leds-gpio: try to lookup gpiod from device
   - leds-as3645a: convert to using %pOFn instead of device_node.name"

114b5f8f7e This is the bulk of GPIO changes for the v4.20 series:
Core changes:
 
 - A patch series from Hans Verkuil to make it possible to
   enable/disable IRQs on a GPIO line at runtime and drive GPIO
   lines as output without having to put/get them from scratch.
   The irqchip callbacks have been improved so that they can
   use only the fastpatch callbacks to enable/disable irqs
   like any normal irqchip, especially the gpiod_lock_as_irq()
   has been improved to be callable in fastpath context.
   A bunch of rework had to be done to achieve this but it is
   a big win since I never liked to restrict this to slowpath.
   The only call requireing slowpath was try_module_get() and
   this is kept at the .request_resources() slowpath callback.
   In the GPIO CEC driver this is a big win sine a single
   line is used for both outgoing and incoming traffic, and
   this needs to use IRQs for incoming traffic while actively
   driving the line for outgoing traffic.
 
 - Janusz Krzysztofik improved the GPIO array API to pass a
   "cookie" (struct gpio_array) and a bitmap for setting or
   getting multiple GPIO lines at once. This improvement
   orginated in a specific need to speed up an OMAP1 driver and
   has led to a much better API and real performance gains
   when the state of the array can be used to bypass a lot
   of checks and code when we want things to go really fast.
   The previous code would minimize the number of calls
   down to the driver callbacks assuming the CPU speed was
   orders of magnitude faster than the I/O latency, but this
   assumption was wrong on several platforms: what we needed
   to do was to profile and improve the speed on the hot
   path of the array functions and this change is now
   completed.
 
 - Clean out the painful and hard to grasp BNF experiments
   from the device tree bindings. Future approaches are looking
   into using JSON schema for this purpose. (Rob Herring
   is floating a patch series.)
 
 New drivers:
 
 - The RCAR driver now supports r8a774a1 (RZ/G2M).
 
 - Synopsys GPIO via CREGs driver.
 
 Major improvements:
 
 - Modernization of the EP93xx driver to use irqdomain and
   other contemporary concepts.
 
 - The ingenic driver has been merged into the Ingenic pin
   control driver and removed from the GPIO subsystem.
 
 - Debounce support in the ftgpio010 driver.

Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree:

1) rbtree lookup from control plane returns the left-hand side element
   of the range when the interval end flag is set on.

2) osf extension is not supported from the input path, reject this from
   the control plane, from Fernando Fernandez Mancera.

3) xt_TEE is leaving output interface unset due to a recent incorrect
   netns rework, from Taehee Yoo.

4) xt_TEE allows to select an interface which does not belong to this
   netnamespace, from Taehee Yoo.

5) Zero private extension area in nft_compat, just like we do in x_tables,
   otherwise we leak kernel memory to userspace.

6) Missing .checkentry and .destroy entries in new DNAT extensions breaks
   it since we never load nf_conntrack dependencies, from Paolo Abeni.

7) Do not remove flowtable hook from netns exit path, the netdevice handler
   already deals with this, also from Taehee Yoo.

8) Only cleanup flowtable entries that reside in this netnamespace, also
   from Taehee Yoo.

====================
octeontx2-af: NPC parser and NIX blocks initialization

This patchset is a continuation to earlier submitted two patch
series to add a new driver for Marvell's OcteonTX2 SOC's
Resource virtualization unit (RVU) admin function driver.

1. octeontx2-af: Add RVU Admin Function driver
   https://www.spinics.net/lists/netdev/msg528272.html
2. octeontx2-af: NPA and NIX blocks initialization
   https://www.spinics.net/lists/netdev/msg529163.html

This patch series adds more NIX block configuration logic
and additionally adds NPC block parser profile configuration.
In brief below is what this series adds.
NIX block:
- Support for PF/VF to allocate/free transmit scheduler queues,
  maintenance and their configuration.
- Adds support for packet replication lists, only broadcast
  packets is covered for now.
- Defines few RSS flow algorithms for HW to distribute packets.
  This is not the hash algorithsm (i.e toeplitz or crc32), here SW
  defines what fields in packet should HW take and calculate the hash.
- Support for PF/VF to configure VTAG strip and capture capabilities.
- Reset NIXLF statastics.

NPC block:
This block has multiple parser engines which support packet parsing
at multiple layers and generates a parse result which is further used
to generate a key. Based on packet field offsets in the key, SW can
install packet forwarding rules.
This patch series adds
- Initial parser profile to be programmed into parser engines.
- Default forwarding rules to forward packets to different logical
  interfaces having a NIXLF attached.
- Support for promiscuous and multicast modes.

Changes from v1:
 1 Fixed kernel build failure when compiled with BIG_ENDIAN enabled.
   - Reported by Kbuild test robot
 2 Fixed a warning observed when kernel is built with -Wunused-but-set-variable

d6f092ca92 octeontx2-af: Support for NIXLF's UCAST/PROMISC/ALLMULTI modes
By default NIXLF is set in UCAST mode. This patch adds a new
mailbox message which when sent by a RVU PF changes this default
mode. When promiscuous mode is needed, the reserved promisc entry
for each of RVU PF is setup to match against ingress channel number
only, so that all pkts on that channel are accepted and forwarded
to the mode change requesting PF_FUNC's NIXLF.

PROMISC and ALLMULTI modes are supported only for PFs, for VFs only
UCAST mode is supported.

Configure NIX RX flowkey algorithm configuration to support
RSS (receive side scaling). Currently support for only L3/L4
2-tuple and 4-tuple hash of IPv4/v6/TCP/UDP/SCTP is added.
HW supports upto 32 different flowkey algorithms which SW
can define, this patch defines 9. NPC RX ACTION has to point
to one of these flowkey indices for RSS to work.

The configuration is dependent on NPC parse result's layer
info. So if NPC KPU profile changes suchthat LID/LTYPE values
of above said protocols change then this configuration will
most likely be effected.

b279bbb331 octeontx2-af: NIX Tx scheduler queue config support
This patch adds support for a PF/VF driver to configure
NIX transmit scheduler queues via mbox. Since PF/VF doesn't
know the absolute HW index of the NIXLF attached to it, AF
traps the register config and overwrites with the correct
NIXLF index.

HW supports shaping, colouring and policing of packets with
these multilevel traffic scheduler queues. Instead of
introducing different mbox message formats for different
configurations and making both AF & PF/VF driver implementation
cumbersome, access to the scheduler queue's CSRs is provided
via mbox. AF checks whether the sender PF/VF has the
corresponding queue allocated or not and dumps the config
to HW. With a single mbox msg 20 registers can be configured.

604d415e2b llc: do not use sk_eat_skb()
syzkaller triggered a use-after-free [1], caused by a combination of
skb_get() in llc_conn_state_process() and usage of sk_eat_skb()

sk_eat_skb() is assuming the skb about to be freed is only used by
the current thread. TCP/DCCP stacks enforce this because current
thread holds the socket lock.

llc_conn_state_process() wants to make sure skb does not disappear,
and holds a reference on the skb it manipulates. But as soon as this
skb is added to socket receive queue, another thread can consume it.

This means that llc must use regular skb_unlink() and kfree_skb()
so that both producer and consumer can safely work on the same skb.

ec7f0ee2c1 Merge branch 'forbid-goto_chain-fallback'
Davide Caratti says:

====================
net/sched: forbid 'goto_chain' on fallback actions

the following command:

 # tc actions add action police rate 1mbit burst 1k conform-exceed \
 > pass / goto chain 42

generates a NULL pointer dereference when packets exceed the configured
rate. Similarly, the following command:

 # tc actions add action pass random determ goto chain 42 2

makes the kernel crash with NULL dereference when the first packet does
not match the 'pass' action.

gact and police allow users to specify a fallback control action, that is
stored in the action private data. 'goto chain x' never worked for these
cases, since a->goto_chain handle was never initialized. There is only one
goto_chain handle per TC action, and it is designed to be non-NULL only if
tcf_action contains a 'goto chain' command. So, let's forbid 'goto chain'
on fallback actions.

Patch 1/4 and 2/4 change the .init() functions of police and gact, to let
them return an error when users try to set 'goto chain x' in the fallback
action. Patch 3/4 and 4/4 add TDC selftest coverage to this new behavior.

876dcf2f3a umh: Add command line to user mode helpers
User mode helpers were spawned without a command line, and because
an empty command line is used by many tools to identify processes as
kernel threads, this could cause some issues.

Notably during killing spree on shutdown, since such helper would then
be skipped (i.e. not killed) which would result in the process remaining
alive, and thus preventing unmouting of the rootfs (as experienced with
the bpfilter umh).
