Allow sending a packet to conntrack module for connection tracking.
The packet will be marked with conntrack connection's state, and
any metadata such as conntrack mark and label. This state metadata
can later be matched against with tc classifers, for example with the
flower classifier as below.
In addition to committing new connections the user can optionally
specific a zone to track within, set a mark/label and configure nat
with an address range and port range.
Usage is as follows:
$ tc qdisc add dev ens1f0_0 ingress
$ tc qdisc add dev ens1f0_1 ingress
$ tc filter add dev ens1f0_0 ingress \
prio 1 chain 0 proto ip \
flower ip_proto tcp ct_state -trk \

devlink: Introduce PCI PF, VF ports and attributes
This patchset carry forwards the work initiated in [1] and discussion
futher concluded at [2].
To improve visibility of representor netdevice, its association with
PF or VF, physical port, two new devlink port flavours are added as
PCI PF and PCI VF ports.
A sample eswitch view can be seen below, which will be futher extended to
mdev subdevices of a PCI function in future.
Patch-1 moves physical port's attribute to new structure
Patch-2 enhances netlink response to consider port flavour
Patch-3,4 extends devlink port attributes and port flavour
Patch-5 extends mlx5 driver to register devlink ports for PF, VF and
physical link.

[2] https://marc.info/?l=linux-netdev&m=155354609408485&w=2
Changelog:
v5->v6:
- Fixed port flavour check order for PCI PF vs other flavours in
netlink response.
- Changed 'physical' to 'phys'.
v4->v5:
- Split first patch to two patches to handle netlink response in
separate patch.
- Corrected typo 'otwerwise' to 'otherwise' in patches 3 and 4.
v3->v4:
- Addressed comments from Jiri.
- Split first patch to two patches.
- Renamed phys_port to physical to be consistent with pci_pf.
- Removed port_number from __devlink_port_attrs_set and moved
assignment to caller function.
- Used capital letter while moving old comment to new structure.
- Removed helper function is_devlink_phy_port_num_supported().
v2->v3:
- Made port_number and split_port_number applicable only to
physical port flavours.
v1->v2:
- Updated new APIs and mlx5 driver to drop port_number for PF, VF
attributes
- Updated port_number comment for its usage
- Limited putting port_number to physical ports

Register devlink port of physical port, PCI PF and PCI VF flavour
for each PF, VF when a given devlink instance is in switchdev mode.
Implement ndo_get_devlink_port callback API to make use of registered
devlink ports.
This eliminates ndo_get_phys_port_name() and ndo_get_port_parent_id()
callbacks. Hence, remove them.
An example output with 2 VFs, without a PF and single uplink port is
below.

In an eswitch, PCI VF may have port which is normally represented using
a representor netdevice.
To have better visibility of eswitch port, its association with VF,
and its representor netdevice, introduce a PCI VF port flavour.
When devlink port flavour is PCI VF, fill up PCI VF attributes of
the port.
Extend port name creation using PCI PF and VF number scheme on best
effort basis, so that vendor drivers can skip defining their own scheme.

Including:
- Patches to make the dma-iommu code more generic so that it can
be used outside of the ARM context with other IOMMU drivers.
Goal is to make use of it on x86 too.
- Generic IOMMU domain support for the Intel VT-d driver. This
driver now makes more use of common IOMMU code to allocate
default domains for the devices it handles.
- An IOMMU fault reporting API to userspace. With that the IOMMU
fault handling can be done in user-space, for example to
forward the faults to a VM.
- Better handling for reserved regions requested by the
firmware. These can be 'relaxed' now, meaning that those don't
prevent a device being attached to a VM.
- Suspend/Resume support for the Renesas IOMMU driver.
- Added support for dumping SVA related fields of the DMAR table
in the Intel VT-d driver via debugfs.
- A pile of smaller fixes and cleanups.

For the most part this is a quiet release for SPI, though there's
several of the more widely used drivers that have had some fairly
substantial development done on them, mainly improving
performance and adding support for some more obscure use cases.
- Support for configuring a minimum time for chip select to be
deasserted between transfers from Martin Sperl.
- A rework of the ACPI device instantiation code from Ard
Biesheuvel.
- Fairly substantial development on the AT91 USART, BCM2835 and
Tegra114 drivers.
- New driver for Socionext SynQuacer.

Pull GPIO updates from Linus Walleij:
"This is the big slew of GPIO changes for the v5.3 kernel cycle. This
is mostly incremental work this time.
Three important things:
- The FMC subsystem is deleted through my tree. This happens through
GPIO as its demise was discussed in relation to a patch decoupling
its GPIO implementation from the standard way of handling GPIO. As
it turns out, that is not the only subsystem it reimplements and
the authors think it is better do scratch it and start over using
the proper kernel subsystems than try to polish the rust shiny. See
the commit (ACKed by the maintainers) for details.
- Arnd made a small devres patch that was ACKed by Greg and goes into
the device core.
- SPDX header change colissions may happen, because at times I've
seen that quite a lot changed during the -rc:s in regards to SPDX.
(It is good stuff, tglx has me convinced, and it is worth the
occasional pain.)
Apart from this is is nothing controversial or problematic.
Summary:
Core:

Pull force_sig() argument change from Eric Biederman:
"A source of error over the years has been that force_sig has taken a
task parameter when it is only safe to use force_sig with the current
task.
The force_sig function is built for delivering synchronous signals
such as SIGSEGV where the userspace application caused a synchronous
fault (such as a page fault) and the kernel responded with a signal.
Because the name force_sig does not make this clear, and because the
force_sig takes a task parameter the function force_sig has been
abused for sending other kinds of signals over the years. Slowly those
have been fixed when the oopses have been tracked down.
This set of changes fixes the remaining abusers of force_sig and
carefully rips out the task parameter from force_sig and friends
making this kind of error almost impossible in the future"

nfp: tls: fixes for initial TLS support
This series brings various fixes to nfp tls offload recently added
to net-next.
First 4 patches revolve around device mailbox communication, trying
to make it more reliable. Next patch fixes statistical counter.
Patch 6 improves the TX resync if device communication failed.
Patch 7 makes sure we remove keys from memory after talking to FW.
Patch 8 adds missing tls context initialization, we fill in the
context information from various places based on the configuration
and looks like we missed the init in the case of where TX is
offloaded, but RX wasn't initialized yet. Patches 9 and 10 make
the nfp driver undo TLS state changes if we need to drop the
frame (e.g. due to DMA mapping error).
Last but not least TLS fallback should not adjust socket memory
after skb_orphan_partial(). This code will go away once we forbid
orphaning of skbs in need of crypto, but that's "real" -next
material, so lets do a quick fix.
====================

netem runs skb_orphan_partial() which "disconnects" the skb
from normal TCP write memory accounting. We should not adjust

Turns out TLS_TX in HW offload mode does not initialize tls_prot_info.
Since commit 9cd81988cc ("net/tls: use version from prot") we actually
use this field on the datapath. Luckily we always compare it to TLS 1.3,
and assume 1.2 otherwise. So since zero is not equal to 1.3, everything
worked fine.

Introduce a return code for the tls_dev_resync callback.
When the driver TX resync fails, kernel can retry the resync again
until it succeeds. This prevents drivers from attempting to offload
TLS packets if the connection is known to be out of sync.
We don't worry about the RX resync since they will be retried naturally
as more encrypted records get received.

Increase the batch limit to consume small message bursts more
effectively. Practically, the effect on the 'add' messages is not
significant since the mailbox is sized such that the 'add' messages are
still limited to the same order of magnitude that it was originally set
for.
Furthermore, increase the queue size limit to 1024 entries. This further
improves the handling of bursts of small control messages.

Connection 4 tuple reuse is slightly problematic - TLS socket
and context do not get destroyed until all the associated skbs
left the system and all references are released. This leads
to stale connection entry in the device preventing addition
of new one if the 4 tuple is reused quickly enough.
Instead of using read 4 tuple as the key use a unique ID.
Set the protocol to TCP and port to 0 to ensure no collisions
with real connections.
