This patch cleans up promiscuous configuration when a VF reset occurs.
Previously the promiscuous mode settings were still there after the VF

In the case of implicit connect message with data > 1K, the flow
control accounting is incorrect. At this state, the socket does not
know the peer nodes capability and falls back to legacy flow control
by return 1, however the receiver of this message will perform the
new block accounting. This leads to a slack and eventually traffic
disturbance.
In this commit, we perform tipc_node_get_capabilities() at implicit
connect and perform accounting based on the peer's capability.

During socket close, if there is a open record with tx context, it needs
to be be freed apart from freeing up plaintext and encrypted scatter
lists. This patch frees up the open record if present in tx context.
Also tls_free_both_sg() has been renamed to tls_free_open_rec() to
indicate that the free record in tx context is being freed inside the
function.

Current async encryption implementation sometimes showed up socket
memory accounting error during socket close. This results in kernel
warning calltrace. The root cause of the problem is that socket var
sk_forward_alloc gets corrupted due to access in sk_mem_charge()
and sk_mem_uncharge() being invoked from multiple concurrent contexts
in multicore processor. The apis sk_mem_charge() and sk_mem_uncharge()
are called from functions alloc_plaintext_sg(), free_sg() etc. It is
required that memory accounting apis are called under a socket lock.
The plaintext sg data sent for encryption is freed using free_sg() in
tls_encryption_done(). It is wrong to call free_sg() from this function.
This is because this function may run in irq context. We cannot acquire
socket lock in this function.
We remove calling of function free_sg() for plaintext data from
tls_encryption_done() and defer freeing up of plaintext data to the time
when the record is picked up from tx_list and transmitted/freed. When
tls_tx_records() gets called, socket is already locked and thus there is
no concurrent access problem.

If SMMU is on, there is more likely that skb_shinfo(skb)->frags[i]
can not send by a single BD. when this happen, the
hns_nic_net_xmit_hw function map the whole data in a frags using
skb_frag_dma_map, but unmap each BD' data individually when tx is
done, which causes problem when SMMU is on.
This patch fixes this problem by ummapping the whole data in a
frags when tx is done.

Both len and off are frontend specified values, so we need to make
sure there's no overflow when adding the two for the bounds check. We
also want to avoid undefined behavior and hence use off to index into
->hash.mapping[] only after bounds checking. This at the same time
allows to take care of not applying off twice for the bounds checking
against vif->num_queues.
It is also insufficient to bounds check copy_op.len, as this is len
truncated to 16 bits.
This is XSA-270 / CVE-2018-15471.

BPF flow dissectors are configured per network namespace.
__skb_flow_dissect looks up the netns through dev_net(skb->dev).
In some dissector paths skb->dev is NULL, such as for Unix sockets.
In these cases fall back to looking up the netns by socket.
Analyzing the codepaths leading to __skb_flow_dissect I did not find
a case where both skb->dev and skb->sk are NULL. Warn and fall back to
standard flow dissector if one is found.

Currently associativity is used to lookup node-id even if the
preceding VPHN hcall failed. However this can cause CPU to be made
part of the wrong node, (most likely to be node 0). This is because
VPHN is not enabled on KVM guests.
With 2ea6263 ("powerpc/topology: Get topology for shared processors at
boot"), associativity is used to set to the wrong node. Hence KVM
guest topology is broken.
For example : A 4 node KVM guest before would have reported.
[root@localhost ~]# numactl -H
available: 4 nodes (0-3)
node 0 cpus: 0 1 2 3
node 0 size: 1746 MB
node 0 free: 1604 MB
node 1 cpus: 4 5 6 7
node 1 size: 2044 MB
node 1 free: 1765 MB
node 2 cpus: 8 9 10 11
node 2 size: 2044 MB
node 2 free: 1837 MB
node 3 cpus: 12 13 14 15
node 3 size: 2044 MB
node 3 free: 1903 MB
node distances:
node 0 1 2 3
0: 10 40 40 40
1: 40 10 40 40
2: 40 40 10 40
3: 40 40 40 10
Would now report:
[root@localhost ~]# numactl -H
available: 4 nodes (0-3)
node 0 cpus: 0 2 3 4 5 6 7 8 9 10 11 12 13 14 15
node 0 size: 1746 MB
node 0 free: 1244 MB
node 1 cpus:
node 1 size: 2044 MB
node 1 free: 2032 MB
node 2 cpus: 1
node 2 size: 2044 MB
node 2 free: 2028 MB
node 3 cpus:

Current we store the userspace r1 to PACATMSCRATCH before finally
saving it to the thread struct.
In theory an exception could be taken here (like a machine check or
SLB miss) that could write PACATMSCRATCH and hence corrupt the
userspace r1. The SLB fault currently doesn't touch PACATMSCRATCH, but
others do.
We've never actually seen this happen but it's theoretically
possible. Either way, the code is fragile as it is.
This patch saves r1 to the kernel stack (which can't fault) before we
turn MSR[RI] back on. PACATMSCRATCH is still used but only with
MSR[RI] off. We then copy r1 from the kernel stack to the thread
struct once we have MSR[RI] back on.

When we treclaim we store the userspace checkpointed r13 to a scratch
SPR and then later save the scratch SPR to the user thread struct.
Unfortunately, this doesn't work as accessing the user thread struct
can take an SLB fault and the SLB fault handler will write the same
scratch SPRG that now contains the userspace r13.
To fix this, we store r13 to the kernel stack (which can't fault)
before we access the user thread struct.
Found by running P8 guest + powervm + disable_1tb_segments + TM. Seen
as a random userspace segfault with r13 looking like a kernel address.

This reverts commit 55aedef50d4d810670916d9fce4a40d5da2079e7.
Commit 55aedef50d4d ("pinctrl: intel: Do pin translation when lock IRQ")
added special translation from GPIO number to hardware pin number to
irq_reqres/relres hooks to avoid failure when IRQs are requested. The
actual failure happened inside gpiochip_lock_as_irq() because it calls
gpiod_get_direction() and pinctrl-intel.c::intel_gpio_get_direction()
implementation originally missed the translation so the two hooks made
it work by skipping the ->get_direction() call entirely (it overwrote
the default GPIOLIB provided functions).
The proper fix that adds translation to GPIO callbacks was merged with
commit 96147db1e1df ("pinctrl: intel: Do pin translation in other GPIO
operations as well"). This allows us to use the default GPIOLIB provided
functions again.
In addition as find out by Benjamin Tissoires the two functions
(intel_gpio_irq_reqres()/intel_gpio_irq_relres()) now cause problems of
their own because they operate on pin numbers and pass that pin number
to gpiochip_lock_as_irq() which actually expects a GPIO number.

From the AMD BKDG, if WAKE_INT_MASTER_REG.MaskStsEn is set, a software
write to the debounce registers of *any* gpio will block wake/interrupt
status generation for *all* gpios for a length of time that depends on
WAKE_INT_MASTER_REG.MaskStsLength[11:0]. During this period the Interrupt
Delivery bit (INTERRUPT_ENABLE) will read as 0.
In commit 4c1de0414a1340 ("pinctrl/amd: poll InterruptEnable bits in
enable_irq") we tried to fix this same "gpio Interrupts are blocked
immediately after writing debounce registers" problem, but incorrectly
assumed it only affected the gpio whose debounce was being configured
and not ALL gpios.
To solve this for all gpios, we move the polling loop from
amd_gpio_irq_enable() to amd_gpio_irq_set_type(), while holding the gpio
spinlock. This ensures that another gpio operation (e.g.
amd_gpio_irq_unmask()) can read a temporarily disabled IRQ and
incorrectly disable it while trying to modify some other register bits.

In the iommu's shutdown handler we disable runtime-pm which could
result in the irq-handler running unclocked and since commit
3fc7c5c0cff3 ("iommu/rockchip: Handle errors returned from PM framework")
we warn about that fact.
This can cause warnings on shutdown on some Rockchip machines, so
free the irqs in the shutdown handler before we disable runtime-pm.

Add DEVX information to WQ, SRQ, CQ, TIR, TIS, QP,
RQ, XRCD, PD, MKEY and MCG.
Each object that is created/destroyed/modified via verbs will
be stamped with a UID based on its user context. This is already
done for DEVX objects commands.
This will enable the firmware to enforce the usage of kernel objects
from the DEVX flow by validating that the same UID is used and the
resources are really related to the same user.
The addition of *_valid fields are needed to distinguish
how various addresses are passed.
For non-DEVX callers, all those fields will be zero.

Set uid as part of DCT commands so that the firmware can manage the
DCT object in a secured way.
That will enable using a DCT that was created by verbs application
to be used by the DEVX flow in case the uid is equal.

Set uid as part of CQ commands so that the firmware can manage the CQ
object in a secured way.
The firmware should mark this CQ with the given uid so that it can
be used later on only by objects with the same uid.
Upon DEVX flows that use this CQ (e.g. create QP command), the
pointed CQ must have the same uid as of the issuer uid command.
When a command is issued with uid=0 it means that the issuer of the
command is trusted (i.e. kernel), in that case any pointed object
can be used regardless of its uid.

We shouldn't attempt to DMA map the message buffers passed into this
driver from the i2c core unless the message we're mapping have been
properly setup for DMA. The i2c core indicates such a situation by
setting the I2C_M_DMA_SAFE flag, so check for that flag before using DMA
mode. We can also bounce the buffer if it isn't already mapped properly
by using the i2c_get_dma_safe_msg_buf() APIs, so do that when we
want to use DMA for a message.
This fixes a problem where the kernel oopses cleaning pages for a buffer
that's mapped into the vmalloc space. The pages are returned from
request_firmware() and passed down directly to the i2c master to write
to the i2c touchscreen device. Mapping vmalloc buffers with
dma_map_single() won't work reliably, causing an oops like below:
Unable to handle kernel paging request at virtual address ffffffc01391d000

Building a riscv kernel with CONFIG_FUNCTION_TRACER and
CONFIG_MODVERSIONS enabled results in these two warnings:
MODPOST vmlinux.o
WARNING: EXPORT symbol "return_to_handler" [vmlinux] version generation failed, symbol will not be versioned.
WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
When exporting symbols from an assembly file, the MODVERSIONS code
requires their prototypes to be defined in asm-prototypes.h (see
scripts/Makefile.build). Since both of these symbols have prototypes
defined in linux/ftrace.h, include this header from RISC-V's
asm-prototypes.h.

Until now, the Rx flow hash key was a 5-tuple (IP src, IP dst,
IP nextproto, L4 src port, L4 dst port) fixed value that we
configured at probe.
Add support for configuring this hash key at runtime.
We support all standard header fields configurable through ethtool,
but cannot differentiate between flow types, so the same hash key
is applied regardless of protocol.
We also don't support the discard option.

With CONFIG_DMA_API_DEBUG enabled we get DMA unmapping warning in
various places of the mvneta driver, for example when putting down an
interface while traffic is passing through.
The issue is when using s/w buffer management, the Rx buffers are mapped
using dma_map_page but unmapped with dma_unmap_single. This patch fixes
this by using the right unmapping function.
