When a Raw Ethernet QP is created, we actually create a few objects.
One of these objects is a TIR. Currently, a TIR could hash (and spread
the traffic) by IP or port only. Adding a hashing by IPSec SPI to TIR
creation with the required UAPI bit.

Users should be able to query for IPSec support. Adding a few
capabilities bits as part of the driver specific part in
alloc_ucontext:
MLX5_USER_ALLOC_UCONTEXT_FLOW_ACTION_FLAGS_ESP_AES_GCM_REQ_METADATA
Payload's header is returned with metadata representing the
IPSec decryption state.
MLX5_USER_ALLOC_UCONTEXT_FLOW_ACTION_FLAGS_ESP_AES_GCM_RX
Support ESP_AES_GCM in ingress path.
MLX5_USER_ALLOC_UCONTEXT_FLOW_ACTION_FLAGS_ESP_AES_GCM_TX
Support ESP_AES_GCM in egress path.
MLX5_USER_ALLOC_UCONTEXT_FLOW_ACTION_FLAGS_ESP_AES_GCM_SPI_RSS_ONLY
Hardware doesn't support matching SPI in flow steering rules
but just hashing and spreading the traffic accordingly.

flow_actions of ESP type could be modified during runtime. This could be
common for example when ESN should be changed. Adding a new
UVERBS_FLOW_ACTION_ESP_MODIFY method for changing ESP parameters of an
existing ESP flow_action.
The new method uses the UVERBS_FLOW_ACTION_ESP_CREATE attributes, but
adds a new IB_FLOW_ACTION_ESP_FLAGS_MOD_ESP_ATTRS which means ESP_ATTRS
should be changed.
In addition, we add a new FLOW_ACTION_ESP_REPLAY_NONE replay type that
could be used when one wants to disable a replay protection over a
specific flow_action.

Binding a flow_action to flow steering rule requires using a new
specification. Therefore, adding such an IB_FLOW_SPEC_ACTION_HANDLE flow
specification.
Flow steering rules could use flow_action(s) and as of that we need to
avoid deleting flow_action(s) as long as they're being used.
Moreover, when the attached rules are deleted, action_handle reference
count should be decremented. Introducing a new mechanism of flow
resources to keep track on the attached action_handle(s). Later on, this
mechanism should be extended to other attached flow steering resources
like flow counters.

A verbs application may receive and transmits packets using a data
path pipeline. Sometimes, the first stage in the receive pipeline or
the last stage in the transmit pipeline involves transforming a
packet, either in order to make it easier for later stages to process
it or to prepare it for transmission over the wire. Such transformation
could be stripping/encapsulating the packet (i.e. vxlan),
decrypting/encrypting it (i.e. ipsec), altering headers, doing some
complex FPGA changes, etc.
Some hardware could do such transformations without software data path
intervention at all. The flow steering API supports steering a
packet (either to a QP or dropping it) and some simple packet
immutable actions (i.e. tagging a packet). Complex actions, that may
change the packet, could bloat the flow steering API extensively.
Sometimes the same action should be applied to several flows.
In this case, it's easier to bind several flows to the same action and
modify it than change all matching flows.
Introducing a new flow_action object that abstracts any packet
transformation (out of a standard and well defined set of actions).
This flow_action object could be tied to a flow steering rule via a
new specification.
Currently, we support esp flow_action, which encrypts or decrypts a
packet according to the given parameters. However, we present a
flexible schema that could be used to other transformation actions tied
to flow rules.

The current implementation of kern_spec_to_ib_spec_filter, which takes
a uAPI based flow steering specification and creates the respective kernel
API flow steering structure, gets a ib_uverbs_flow_spec structure.
The new flow_action uAPI gets a match mask and filter from user-space
which aren't encoded in the flow steering's ib_uverbs_flow_spec structure.
Exporting the logic out of kern_spec_to_ib_spec_filter to get user-space
blobs rather than ib_uverbs_flow_spec structure.

Methods sometimes need to get one attribute out of a group of
pre-defined attributes. This is an enum-like behavior. Since
this is a common requirement, we add a new ENUM attribute to the
generic uverbs ioctl() layer. This attribute is embedded in methods,
like any other attributes we currently have. ENUM attributes point to
an array of standard UVERBS_ATTR_PTR_IN. The user-space encodes the
enum's attribute id in the id field and the internal PTR_IN attr id in
the enum_data.elem_id field. This ENUM attribute could be shared by
several attributes and it can get UVERBS_ATTR_SPEC_F_MANDATORY flag,
stating this attribute must be supported by the kernel, like any other
attribute.

In order to have a custom parsing tree, a provider driver needs to
assign its parsing tree to ib_device specs_tree field. Otherwise, the
uverbs client assigns a common default parsing tree for it.
In downstream patches, the mlx5_ib driver gains a custom parsing tree,
which contains both the common objects and a new flags field for the
UVERBS_FLOW_ACTION_ESP_CREATE command.
This patch makes mlx5_ib assign its own tree to specs_root, which
later on will be extended.

The __net_initdata section cannot currently be used for structures that
get cleaned up in an exitcall using unregister_pernet_operations:
WARNING: vmlinux.o(.text+0x868c34): Section mismatch in reference from the function nsim_devlink_exit() to the (unknown reference) .init.data:(unknown)
The function nsim_devlink_exit() references
the (unknown reference) __initdata (unknown).
This is often because nsim_devlink_exit lacks a __initdata
annotation or the annotation of (unknown) is wrong.
WARNING: vmlinux.o(.text+0x868c64): Section mismatch in reference from the function nsim_devlink_init() to the (unknown reference) .init.data:(unknown)
WARNING: vmlinux.o(.text+0x8692bc): Section mismatch in reference from the function nsim_fib_exit() to the (unknown reference) .init.data:(unknown)
WARNING: vmlinux.o(.text+0x869300): Section mismatch in reference from the function nsim_fib_init() to the (unknown reference) .init.data:(unknown)
As that warning tells us, discarding the structure after a module is
loaded would lead to a undefined behavior when that module is removed.
It might be possible to change that annotation so it has no effect for
loadable modules, but I have not figured out exactly how to do that, and
we want this to be fixed in -rc1.
This just removes the annotations, just like we do for all other such
modules.

Commit 519049afead ("dm: use blkdev_get rather than bdgrab when issuing
pass-through ioctl") inadvertantly introduced a regression relative to
users of device cgroups that issue ioctls (e.g. libvirt). Using
blkdev_get() in DM's passthrough ioctl support implicitly introduced a
cgroup permissions check that would fail unless care were taken to add
all devices in the IO stack to the device cgroup. E.g. rather than just
adding the top-level DM multipath device to the cgroup all the
underlying devices would need to be allowed.
Fix this, to no longer require allowing all underlying devices, by
simply holding the live DM table (which includes the table's original
blkdev_get() reference on the blockdevice that the ioctl will be issued
to) for the duration of the ioctl.
Also, bump the DM ioctl version so a user can know that their device
cgroup allow workaround is no longer needed.

The new of_get_nvmem_mac_address() helper function causes a link error
with CONFIG_NVMEM=m:
drivers/of/of_net.o: In function `of_get_nvmem_mac_address':
of_net.c:(.text+0x168): undefined reference to `of_nvmem_cell_get'
of_net.c:(.text+0x19c): undefined reference to `nvmem_cell_read'
of_net.c:(.text+0x1a8): undefined reference to `nvmem_cell_put'
I could not come up with a good solution for this, as the code is always
built-in. Using an #if IS_REACHABLE() check around it would solve the
link time issue but then stop it from working in that configuration.
Making of_nvmem_cell_get() an inline function could also solve that, but
seems a bit ugly since it's somewhat larger than most inline functions,
and it would just bring that problem into the callers. Splitting the
function into a separate file might be an alternative.
This uses the big hammer by making CONFIG_NVMEM itself a 'bool' symbol,
which avoids the problem entirely but makes the vmlinux larger for anyone
that might use NVMEM support but doesn't need it built-in otherwise.

The NSP default buffer is a piece of NFP memory where additional
command data can be placed. Its format has been copied from
host buffer, but the PCIe selection bits do not make sense in
this case. If those get masked out from a NFP address - writes
to random place in the chip memory may be issued and crash the
device.
Even in the general NSP buffer case, it doesn't make sense to have the
PCIe selection bits there anymore. These are unused at the moment, and
when it becomes necessary, the PCIe selection bits should rather be
moved to another register to utilise more bits for the buffer address.
This has never been an issue because the buffer used to be
allocated in memory with less-than-38-bit-long address but that
is about to change.

The culprit is quite simple: The driver tries to access the phy left and right,
but only actually has a working reference to it when the device is up.
The fix thus is quite simple too: Get a reference to the phy on probe already
and keep it even when the device is going down.
With this patch applied, I can successfully run wicked on my system and bring
the interface up and down as many times as I want, without getting NULL pointer
dereferences in between.

Based on the previous patches, this patch supports the LPC host on
Hip06/Hip07 for ACPI FW.
It is the responsibility of the LPC host driver to enumerate the child
devices, as the ACPI scan code will not enumerate children of "indirect IO"
hosts.
The ACPI table for the LPC host controller and the child devices is in the
following format:
Device (LPC0) {
Name (_HID, "HISI0191") // HiSi LPC
Name (_CRS, ResourceTemplate () {
Memory32Fixed (ReadWrite, 0xa01b0000, 0x1000)
})
}
Device (LPC0.IPMI) {
Name (_HID, "IPI0001")
Name (LORS, ResourceTemplate() {
QWordIO (
ResourceConsumer,
MinNotFixed, // _MIF
MaxNotFixed, // _MAF
PosDecode,
EntireRange,
0x0, // _GRA
0xe4, // _MIN
0x3fff, // _MAX
0x0, // _TRA
0x04, // _LEN
, ,
BTIO
)
})
Since the IO resources of the child devices need to be translated from LPC
bus addresses to logical PIO addresses, and we shouldn't modify the
resources of the devices generated in the FW scan, a per-child MFD is
created as a substitute. The MFD IO resources will be the translated bus
addresses of the ACPI child.

Through the logical PIO framework, systems which otherwise have no IO space
access to legacy ISA/LPC devices may access these devices through so-called
"indirect IO" method. In this, IO space accesses for non-PCI hosts are
redirected to a host LLDD to manually generate the IO space (bus) accesses.
Hosts are able to register a region in logical PIO space to map to its bus
address range.
Indirect IO child devices have an associated host-specific bus address.
Special translation is required to map between a logical PIO address for a
device and its host bus address.
Since in the ACPI tables the child device IO resources would be the
host-specific values, it is required the ACPI scan code should not
enumerate these devices, and that this should be the responsibility of the
host driver so that it can "fixup" the resources so that they map to the
appropriate logical PIO addresses.
To avoid enumerating these child devices, add a check from
acpi_device_enumeration_by_parent() as to whether the parent for a device
is a member of a known list of "indirect IO" hosts. For now, the HiSilicon
LPC host controller ID is added.

Currently the ACPI scan has special handling for serial bus slaves, in that
it makes it the responsibility of the slave device's parent to enumerate
the device.
To support other types of slave devices which require the same special
handling but where the bus is not strictly a serial bus, such as devices on
the HiSilicon LPC controller bus, rename acpi_is_serial_bus_slave() to
acpi_device_enumeration_by_parent(), so that the name can fit the wider
purpose.
Also rename the associated device flag acpi_device_flags.serial_bus_slave
to .enumeration_by_parent.

The low-pin-count (LPC) interface of Hip06/Hip07 accesses I/O port space of
peripherals.
Implement the LPC host controller driver which performs the I/O operations
on the underlying hardware. We don't want to touch existing drivers such
as ipmi-bt, so this driver applies the indirect-IO introduced in the
previous patch after registering an indirect-IO node to the indirect-IO
devices list which will be searched by the I/O accessors to retrieve the
host-local I/O port.
The driver config is set as a bool instead of a tristate. The reason here
is that, by the very nature of the driver providing a logical PIO range, it
does not make sense to have this driver as a loadable module. Another more
specific reason is that the Huawei D03 board which includes Hip06 SoC
requires the LPC bus for UART console, so should be built in.

There are some special ISA/LPC devices that work on a specific I/O range
where it is not correct to specify a 'ranges' property in the DTS parent
node as CPU addresses translated from DTS node are only for memory space on
some architectures, such as ARM64. Without the parent 'ranges' property,
of_translate_address() returns an error.
Here we add special handling for this case.
During the OF address translation, some checking will be performed to
identify whether the device node is registered as indirect-IO. If it is,
the I/O translation will be done in a different way from that one of PCI
MMIO. In this way, the I/O 'reg' property of the special ISA/LPC devices
will be parsed correctly.

cxllib_handle_fault() is called by an external driver when it needs to
have the host resolve page faults for a buffer. The buffer can cover
several pages and VMAs. The function iterates over all the pages used
by the buffer, based on the page size of the VMA.
To ensure some stability while processing the faults, the thread T1
grabs the mm->mmap_sem semaphore with read access (R1). However, when
processing a page fault for a single page, one of the underlying
functions, copro_handle_mm_fault(), also grabs the same semaphore with
read access (R2). So the thread T1 takes the semaphore twice.
If another thread T2 tries to access the semaphore in write mode W1
(say, because it wants to allocate memory and calls 'brk'), then that
thread T2 will have to wait because there's a reader (R1). If the
thread T1 is processing a new page at that time, it won't get an
automatic grant at R2, because there's now a writer thread
waiting (T2). And we have a deadlock.
The timeline is:
1. thread T1 owns the semaphore with read access R1
2. thread T2 requests write access W1 and waits
3. thread T1 requests read access R2 and waits
The fix is for the thread T1 to release the semaphore R1 once it got
the information it needs from the current VMA. The address space/VMAs
could evolve while T1 iterates over the full buffer, but in the
unlikely case where T1 misses a page, the external driver will raise a
new page fault when retrying the memory access.

Instead of a converting pointers to unsigned long, just print
them as-is, using %p.
Fixes this warning:
drivers/staging/media/atomisp/pci/atomisp2/css2400/runtime/debug/src/ia_css_debug.c:3012 ia_css_debug_pipe_graph_dump_sp_raw_copy() warn: argument 4 to %08lx specifier is cast from pointer

There's a check at ia_css_vf_configure() to verify if
binary is not null. However, this is called too late:
drivers/staging/media/atomisp/pci/atomisp2/css2400/isp/kernels/vf/vf_1.0/ia_css_vf.host.c:133 ia_css_vf_configure() warn: variable dereferenced before check 'binary' (see line 129)
This test is wrong, as this fuction is only called by
ia_css_binary_fill_info(), in a place that already assumes that
binary is not null, and checks with:
assert(binary != NULL);
So, remove the useless broken extra check.

Checking if a size_t value is bigger than ULONG_INT only makes
sense if building on 64 bits, as warned by:
drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:697 gmin_get_config_var() warn: impossible condition '(*out_len > (~0)) => (0-u32max > u32max)'

There's an implementation for set_pd_base at sh_mmu logic
with is said to be mandatory. However, the implementation
ends by calling a routine that does nothing.
So get rid of this entire nonsense.
