b5f0cf0834 nfp: flower: prevent offload if rhashtable insert fails
For flow offload adds, if the rhash insert code fails, the flow will still
have been offloaded but the reference to it in the driver freed.

Re-order the offload setup calls to ensure that a flow will only be written
to FW if a kernel reference is held and stored in the rhashtable. Remove
this hashtable entry if the offload fails.

1166494891 nfp: flower: release metadata on offload failure
Calling nfp_compile_flow_metadata both assigns a stats context and
increments a ref counter on (or allocates) a mask id table entry. These
are released by the nfp_modify_flow_metadata call on flow deletion,
however, if a flow add fails after metadata is set then the flow entry
will be deleted but the metadata assignments leaked.

Add an error path to the flow add offload function to ensure allocated
metadata is released in the event of an offload fail.

b0e3f1bdf9 net: Add trace events for all receive exit points
Trace events are already present for the receive entry points, to indicate
how the reception entered the stack.

This patch adds the corresponding exit trace events that will bound the
reception such that all events occurring between the entry and the exit
can be considered as part of the reception context. This greatly helps
for dependency and root cause analyses.

Without this, it is not possible with tracepoint instrumentation to
determine whether a sched_wakeup event following a netif_receive_skb
event is the result of the packet reception or a simple coincidence after
further processing by the thread. It is possible using other mechanisms
like kretprobes, but considering the "entry" points are already present,
it would be good to add the matching exit events.

In addition to linking packets with wakeups, the entry/exit event pair
can also be used to perform network stack latency analyses.

3b5b3a3331 bonding: fix 802.3ad state sent to partner when unbinding slave
Previously when unbinding a slave the 802.3ad implementation only told
partner that the port is not suitable for aggregation by setting the port
aggregation state from aggregatable to individual. This is not enough. If the
physical layer still stays up and we only unbinded this port from the bond there
is nothing in the aggregation status alone to prevent the partner from sending
traffic towards us. To ensure that the partner doesn't consider this
port at all anymore we should also disable collecting and distributing to
signal that this actor is going away. Also clear AD_STATE_SYNCHRONIZATION to
ensure partner exits collecting + distributing state.

I have tested this behaviour againts Arista EOS switches with mlx5 cards
(physical link stays up even when interface is down) and simulated
the same situation virtually Linux <-> Linux with two network namespaces
running two veth device pairs. In both cases setting aggregation to
individual doesn't alone prevent traffic from being to sent towards this
port given that the link stays up in partners end. Partner still keeps
it's end in collecting + distributing state and continues until timeout is
reached. In most cases this means we are losing the traffic partner sends
towards our port while we wait for timeout. This is most visible with slow
periodic time (LACP rate slow).

Other open source implementations like Open VSwitch and libreswitch, and
vendor implementations like Arista EOS, seem to disable collecting +
distributing to when doing similar port disabling/detaching/removing change.
With this patch kernel implementation would behave the same way and ensure
partner doesn't consider our actor viable anymore.

37c4b91f95 net: aquantia: fix rx checksum offload bits
The last set of csum offload fixes had a leak:

Checksum enabled status bits from rx descriptor were incorrectly
interpreted. Consequently all the other valid logic worked on zero bits.
That caused rx checksum offloads never to trigger.

Tested by dumping rx descriptors and validating resulting csum_level.

5f2b8b6278 net: stmmac: Move debugfs init/exit to ->probe()/->remove()
Setting up and tearing down debugfs is current unbalanced, as seen by
this error during resume from suspend:

    [  752.134067] dwc-eth-dwmac 2490000.ethernet eth0: ERROR failed to create debugfs directory
    [  752.134347] dwc-eth-dwmac 2490000.ethernet eth0: stmmac_hw_setup: failed debugFS registration

The imbalance happens because the driver creates the debugfs hierarchy
when the device is opened and tears it down when the device is closed.
There's little gain in that, and it could be argued that it is even
surprising because it's not usually done for other devices. Fix the
imbalance by moving the debugfs creation and teardown to the driver's
->probe() and ->remove() implementations instead.

Note that the ring descriptors cannot be read while the interface is
down, so make sure to return an empty file when the descriptors_status
debugfs file is read.

4135cce7fd sctp: update frag_point when stream_interleave is set
sctp_assoc_update_frag_point() should be called whenever asoc->pathmtu
changes, but we missed one place in sctp_association_init(). It would
cause frag_point is zero when sending data.

As says in Jakub's reproducer, if sp->pathmtu is set by socketopt, the
new asoc->pathmtu inherits it in sctp_association_init(). Later when
transports are added and their pmtu >= asoc->pathmtu, it will never
call sctp_assoc_update_frag_point() to set frag_point.

This patch is to fix it by updating frag_point after asoc->pathmtu is
set as sp->pathmtu in sctp_association_init(). Note that it moved them
after sctp_stream_init(), as stream->si needs to be set first.

Frag_point's calculation is also related with datachunk's type, so it
needs to update frag_point when stream->si may be changed in
sctp_process_init().

v1->v2:
  - call sctp_assoc_update_frag_point() separately in sctp_process_init
    and sctp_association_init, per Marcelo's suggestion.

1584f16ca9 drm/v3d: Add support for submitting jobs to the TFU.
The TFU can copy from raster, UIF, and SAND input images to UIF output
images, with optional mipmap generation.  This will certainly be
useful for media EGL image input, but is also useful immediately for
mipmap generation without bogging the V3D core down.

For now we only run the queue 1 job deep, and don't have any hang
recovery (though I don't think we should need it, with TFU).  Queuing
multiple jobs in the HW will require synchronizing the YUV coefficient
regs updates since they don't get FIFOed with the job.

v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain
    why TFU is AUTH, clarify the syncing docs, drop the unused TFU
    interrupt regs (you're expected to use the hub's), don't take
    &bo->base for NULL bos.
v3: Fix a little whitespace alignment (noticed by checkpatch), rebase
    on drm_sched_job_cleanup() changes.

10d443431d ARC: io.h: Implement reads{x}()/writes{x}()
Some ARC CPU's do not support unaligned loads/stores. Currently, generic
implementation of reads{b/w/l}()/writes{b/w/l}() is being used with ARC.
This can lead to misfunction of some drivers as generic functions do a
plain dereference of a pointer that can be unaligned.

Let's use {get/put}_unaligned() helpers instead of plain dereference of
pointer in order to fix. The helpers allow to get and store data from an
unaligned address whilst preserving the CPU internal alignment.
According to [1], the use of these helpers are costly in terms of
performance so we added an initial check for a buffer already aligned so
that the usage of the helpers can be avoided, when possible.

b7cc40c32a ARC: change defconfig defaults to ARCv2
Change the default defconfig (used with 'make defconfig') to the ARCv2
nsim_hs_defconfig, and also switch the default Kconfig ISA selection to
ARCv2.

This allows several default defconfigs (e.g. make defconfig, make
allnoconfig, make tinyconfig) to all work with ARCv2 by default.

Note since we change default architecture from ARCompact to ARCv2
it's required to explicitly mention architecture type in ARCompact
defconfigs otherwise ARCv2 will be implied and binaries will be
generated for ARCv2.

- Change idx variable in DO_TRACE macro to __idx to avoid name conflicts.
    A kvm event had "idx" as a parameter and it confused the macro.
 
  - Fix a race where interrupts would be traced when set_graph_function was set.
    The previous patch set increased a race window that tricked the function graph
    tracer to think it should trace interrupts when it really should not have.
    The bug has been there before, but was seldom hit. Only the last patch series
    made it more common.

f0ad62a631 drm/i915/psr: Get pipe id following atomic guidelines
As stated in struct drm_encoder, crtc field should only be used
by non-atomic drivers.

So here caching the pipe id in intel_psr_enable() what is way more
simple and efficient than at every call to
intel_psr_flush()/invalidate() get the
drm.mode_config.connection_mutex lock to safely be able to get the
pipe id by reading drm_connector_state.crtc.

This should fix the null pointer dereference crash below as the
previous way to get the pipe id was prone to race conditions.

babc5544c2 arm64: dts: clearfog-gt-8k: 1G eth PHY reset signal
This reset signal controls the Marvell 1512 1G PHY.

Note that current implementation queries the PHY over the MDIO bus
(get_phy_device() call from of_mdiobus_register_phy()) before reset
signal deassert. If the PHY reset signal is asserted at boot time, PHY
registration fails. So current code relies on the bootloader to deassert
the reset signal.

0f1f692375 While rewriting the function graph tracer, I discovered a design flaw that
was introduced by a patch that tried to fix one bug, but by doing so created
 another bug. As both bugs corrupt the output (but they do not crash the
 kernel), I decided to fix the design such that it could have both bugs
 fixed. The original fix, fixed time reporting of the function graph tracer
 when doing a max_depth of one. This was code that can test how much the
 kernel interferes with userspace. But in doing so, it could corrupt the time
 keeping of the function profiler.
 
 The issue is that the curr_ret_stack variable was being used for two
 different meanings. One was to keep track of the stack pointer on the
 ret_stack (shadow stack used by the function graph tracer), and the other
 use case was the graph call depth.  Although, the two may be closely
 related, where they got updated was the issue that lead to the two different
 bugs that required the two use cases to be updated differently.
 
 The big issue with this fix is that it requires changing each architecture.
 The good news is, I was able to remove a lot of code that was duplicated
 within the architectures and place it into a single location. Then I could
 make the fix in one place.
 
 I pushed this code into linux-next to let it settle over a week, and before
 doing so, I cross compiled all the affected architectures to make sure that
 they built fine.
 
 In the mean time, I also pulled in a patch that fixes the sched_switch
 previous tasks state output, that was not actually correct.

ea2412dc21 ACPI/IORT: Fix iort_get_platform_device_domain() uninitialized pointer value
Running the Clang static analyzer on IORT code detected the following
error:

Logic error: Branch condition evaluates to a garbage value

in

iort_get_platform_device_domain()

If the named component associated with a given device has no IORT
mappings, iort_get_platform_device_domain() exits its MSI mapping loop
with msi_parent pointer containing garbage, which can lead to erroneous
code path execution.

Initialize the msi_parent pointer, fixing the bug.
