For split virtqueue, we used to depend on the address, length and
flags stored in the descriptor ring for DMA unmapping. This is unsafe
for the case since the device can manipulate the behavior of virtio
driver, IOMMU drivers and swiotlb.
For safety, maintain the DMA address, DMA length, descriptor flags and
next filed of the non indirect descriptors in vring_desc_state_extra
when DMA API is used for virtio as we did for packed virtqueue and use
those metadata for performing DMA operations. Indirect descriptors
should be safe since they are using streaming mappings.
With this the descriptor ring is write only form the view of the
driver.
This slight increase the footprint of the drive but it's not noticed
through pktgen (64B) test and netperf test in the case of virtio-net.

We should not depend on the DMA address, length and flag of descriptor
table since they could be wrote with arbitrary value by the device. So
this patch switches to use the stored one in desc_extra.
Note that the indirect descriptors are fine since they are read-only
streaming mappings.

There are currently two cases where we poll TX vq not in response to a
callback: start xmit and rx napi. We currently do this with callbacks
enabled which can cause extra interrupts from the card. Used not to be
a big issue as we run with interrupts disabled but that is no longer the
case, and in some cases the rate of spurious interrupts is so high
linux detects this and actually kills the interrupt.
Fix up by disabling the callbacks before polling the tx vq.
Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
virtio_disable_cb is currently a nop for split ring with event index.
This is because it used to be always called from a callback when we know
device won't trigger more events until we update the index. However,
now that we run with interrupts enabled a lot we also poll without a
callback so that is different: disabling callbacks will help reduce the
number of spurious interrupts.
Further, if using event index with a packed ring, and if being called
from a callback, we actually do disable interrupts which is unnecessary.
Fix both issues by tracking whenever we get a callback. If that is
the case disabling interrupts with event index can be a nop.
If not the case disable interrupts. Note: with a split ring
there's no explicit "no interrupts" value. For now we write
a fixed value so our chance of triggering an interupt
is 1/ring size. It's probably better to write something
related to the last used index there to reduce the chance
even further. For now I'm keeping it simple.

It's unsafe to operate a vq from multiple threads.
Unfortunately this is exactly what we do when invoking
clean tx poll from rx napi.
Same happens with napi-tx even without the
opportunistic cleaning from the receive interrupt: that races
with processing the vq in start_xmit.
As a fix move everything that deals with the vq to under tx lock.

In order to support running vdpa using vritio_vdpa driver, we need to
create a different kind of MR, one that has 1:1 mapping, since the
addresses referring to virtqueues are dma addresses.
We create the 1:1 MR in mlx5_vdpa_dev_add() only in case firmware
supports the general capability umem_uid_0. The reason for that is that
1:1 MRs must be created with uid == 0 while virtqueue objects can be
created with uid == 0 only when the firmware capability is on.
If the set_map() callback is called with new translations provided
through iotlb, the driver will destroy the 1:1 MR and create a regular
one.

Before SF support was introduced, the DMA device was equal to
mdev->device which was in essence equal to pdev->dev.
With SF introduction this is no longer true. It has already been
handled for vhost_vdpa since the reference to the dma device can from
within mlx5_vdpa. With virtio_vdpa this broke. To fix this we set the
real dma device when initializing the device.
In addition, for the sake of consistency, previous references in the
code to the dma device are changed to vdev->dma_dev.

Merge tag 'pinctrl-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.14 kernel. Not so
much going on. No core changes, just drivers.
The most interesting would be that MIPS Ralink is migrating to pin
control and we have some bindings but not yet code for the Apple M1
pin controller.
New drivers:
- Last merge window we created a driver for the Ralink RT2880. We are
now moving the Ralink SoC pin control drivers out of the MIPS
architecture code and into the pin control subsystem. This concerns
RT288X, MT7620, RT305X, RT3883 and MT7621.
- Qualcomm SM6125 SoC pin control driver.
- Qualcomm spmi-gpio support for PM7325.
- Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)
- Mediatek MT8365 SoC pin controller.
- New device HID for the AMD GPIO controller.
Improvements:
- Pin bias config support for a slew of Renesas pin controllers.
- Incremental improvements and non-urgent bug fixes to the Renesas
SoC drivers.
- Implement irq_set_wake on the AMD pin controller so we can wake up
from external pin events.
Misc:
- Devicetree bindings for the Apple M1 pin controller, we will
probably see a proper driver for this soon as well"

This PR contains a replacement driver for Intel iWarp hardware. This new
driver supports the old ethernet hardware and also newer chips that can do
ROCE. Otherwise this contains the typical mix of patches:
- Driver updates and cleanups for bnxt_re, cxgb4, mlx4, and mlx5
- Many static checker driven code clean ups, including a wide refcount_t
conversion
- Several series for the hns driver, more HIP09 HW capabilities, migration
to new HW register manipulators, and code cleanups
- Minor fixes and improvements in srp, rts, and cm
- Improvements throughout for sysfs related code to use DEVICE_ATTR_*,
make the ib_port sysfs first-class, and overall use sysfs APIs properly
- Intel's new irdma driver replacing i40iw
- rxe general clean ups and Memory Window support

that's just a bunch of data so the diffstat reflects that. Looking beyond that
there's just a bunch of updates all around in various clk drivers. Renesas and
NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall
the driver changes look to be mostly enabling more clks and non-critical fixes
that we could hold until the next merge window.
I'm especially excited about the series from Arnd that graduates clkdev to be
the only implementation of clk_get() and clk_put(). That's a good step in the
right direction to migreate eveerything over to the common clk framework. Now
we don't have to worry about clkdev specific details, they're just part of the
clk API now.
Core:
- clkdev is now the only option, i.e. clk_get()/clk_put() is implemented in
only one place in the kernel instead of in drivers/clk/clkdev.c and in
architectures that want their own implementation
New Drivers:
- Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant Clock

- Qualcomm MDM9607 GCC
- Qualcomm SC8180X display clks

- Qualcomm SM8250 CAMCC (camera)
- Renesas RZ/G2L SoC
- Hisilicon hi3559A SoC
Updates:
- Stop using clock-output-names in ST clk drivers (yay!)
- Support secure mode of STM32MP1 SoCs
- Improve clock support for Actions S500 SoC
- duty cycle setting support on qcom clks
- Add TI am33xx spread spectrum clock support
- Use determine_rate() for the Amlogic pll ops instead of round_rate()
- Restrict Amlogic gp0/1 and audio plls range on g12a/sm1
- Improve Amlogic axg-audio controller error on deferral

Pull networking updates from Jakub Kicinski:
"Core:
- BPF:
- add syscall program type and libbpf support for generating
instructions and bindings for in-kernel BPF loaders (BPF loaders
for BPF), this is a stepping stone for signed BPF programs
- infrastructure to migrate TCP child sockets from one listener to
another in the same reuseport group/map to improve flexibility
of service hand-off/restart
- add broadcast support to XDP redirect
- allow bypass of the lockless qdisc to improving performance (for
pktgen: +23% with one thread, +44% with 2 threads)
- add a simpler version of "DO_ONCE()" which does not require jump
labels, intended for slow-path usage
- virtio/vsock: introduce SOCK_SEQPACKET support
- add getsocketopt to retrieve netns cookie
- ip: treat lowest address of a IPv4 subnet as ordinary unicast
address allowing reclaiming of precious IPv4 addresses
- ipv6: use prandom_u32() for ID generation
- ip: add support for more flexible field selection for hashing
across multi-path routes (w/ offload to mlxsw)
- icmp: add support for extended RFC 8335 PROBE (ping)
- seg6: add support for SRv6 End.DT46 behavior
- mptcp:
- DSS checksum support (RFC 8684) to detect middlebox meddling
- support Connection-time 'C' flag
- time stamping support
- sctp: packetization Layer Path MTU Discovery (RFC 8899)
- xfrm: speed up state addition with seq set
