To fix bridge resource allocation issues when powering PCI bridges with the
pwrctrl driver, introduce APIs to explicitly power on and off all related
devices simultaneously.
Previously, the individual pwrctrl drivers powered on/off the PCI devices
autonomously, without any control from the controller drivers. But to
enforce ordering with respect to powering on the devices, these APIs will
power on/off all the devices at the same time.
The pci_pwrctrl_power_on_devices() API recursively scans the PCI child
nodes, makes sure that pwrctrl drivers are bound to devices, and calls
their power_on() callbacks. If any pwrctrl driver is not bound, it will
return -EPROBE_DEFER.
Similarly, pci_pwrctrl_power_off_devices() API powers off devices
recursively via their power_off() callbacks.
These APIs are expected to be called during the controller probe and
suspend/resume time to power on/off the devices. But before calling these
APIs, the pwrctrl devices should be created using the
pci_pwrctrl_{create/destroy}_devices() APIs.

Previously, the PCI core created pwrctrl devices during pci_scan_device()
on its own and then skipped enumeration of those devices, hoping the
pwrctrl driver would power them on and trigger a bus rescan.
This approach works for endpoint devices directly connected to Root Ports,
but it fails for PCIe switches acting as bus extenders. When the switch
requires pwrctrl support and the pwrctrl driver is not available during
the pwrctrl device creation, its enumeration will be skipped during the
initial PCI bus scan.
This premature scan leads the PCI core to allocate resources (bridge
windows, bus numbers) for the upstream bridge based on available downstream
buses at scan time. For non-hotplug capable bridges, PCI core typically
allocates resources based on the number of buses available during the
initial bus scan, which happens to be just one if the switch is not powered
on and enumerated at that time. When the switch gets enumerated later on,
it will fail due to the lack of upstream resources.
As a result, a PCIe switch powered on by the pwrctrl driver cannot be
reliably enumerated currently. Either the switch has to be enabled in the
bootloader or the switch pwrctrl driver has to be loaded during the pwrctrl
device creation time to work around these issues.
Introduce new APIs to explicitly create and destroy pwrctrl devices from
controller drivers by recursively scanning the PCI child nodes of the
controller. These APIs allow creating pwrctrl devices based on the original
criteria and are intended to be called during controller probe and removal.
These APIs, together with the upcoming APIs for power on/off will allow the
controller drivers to power on all the devices before starting the initial
bus scan, thereby solving the resource allocation issue.

To allow the pwrctrl core to control the power on/off sequences of the
pwrctrl drivers, add the 'struct pci_pwrctrl::power_{on/off}' callbacks and
populate them in the respective pwrctrl drivers.
The pwrctrl drivers still power on the resources on their own now. So there
is no functional change.

When creating containers the setup usually involves using CLONE_NEWNS
via clone3() or unshare(). This copies the caller's complete mount
namespace. The runtime will also assemble a new rootfs and then use
pivot_root() to switch the old mount tree with the new rootfs. Afterward
it will recursively umount the old mount tree thereby getting rid of all
mounts.
On a basic system here where the mount table isn't particularly large
this still copies about 30 mounts. Copying all of these mounts only to
get rid of them later is pretty wasteful.
This is exacerbated if intermediary mount namespaces are used that only
exist for a very short amount of time and are immediately destroyed
again causing a ton of mounts to be copied and destroyed needlessly.
With a large mount table and a system where thousands or ten-thousands
of containers are spawned in parallel this quickly becomes a bottleneck
increasing contention on the semaphore.
Extend open_tree() with a new OPEN_TREE_NAMESPACE flag. Similar to
OPEN_TREE_CLONE only the indicated mount tree is copied. Instead of
returning a file descriptor referring to that mount tree
OPEN_TREE_NAMESPACE will cause open_tree() to return a file descriptor
to a new mount namespace. In that new mount namespace the copied mount
tree has been mounted on top of a copy of the real rootfs.
The caller can setns() into that mount namespace and perform any
additionally required setup such as move_mount() detached mounts in
there.
This allows OPEN_TREE_NAMESPACE to function as a combined
unshare(CLONE_NEWNS) and pivot_root().
A caller may for example choose to create an extremely minimal rootfs:
fd_mntns = open_tree(-EBADF, "/var/lib/containers/wootwoot", OPEN_TREE_NAMESPACE);
This will create a mount namespace where "wootwoot" has become the
rootfs mounted on top of the real rootfs. The caller can now setns()
into this new mount namespace and assemble additional mounts.
This also works with user namespaces:
unshare(CLONE_NEWUSER);
fd_mntns = open_tree(-EBADF, "/var/lib/containers/wootwoot", OPEN_TREE_NAMESPACE);
which creates a new mount namespace owned by the earlier created user
namespace with "wootwoot" as the rootfs mounted on top of the real
rootfs.

Insert Soft Reserved memory into a dedicated soft_reserve_resource tree
instead of the iomem_resource tree at boot. Delay publishing these ranges
into the iomem hierarchy until ownership is resolved and the HMEM path
is ready to consume them.
Publishing Soft Reserved ranges into iomem too early conflicts with CXL
hotplug and prevents region assembly when those ranges overlap CXL
windows.
Follow up patches will reinsert Soft Reserved ranges into iomem after CXL
window publication is complete and HMEM is ready to claim the memory. This
provides a cleaner handoff between EFI-defined memory ranges and CXL
resource management without trimming or deleting resources later.
In the meantime "Soft Reserved" resources will no longer appear in
/proc/iomem, only their results. I.e. with "memmap=4G%4G+0xefffffff"
Before:
100000000-1ffffffff : Soft Reserved
100000000-1ffffffff : dax1.0
100000000-1ffffffff : System RAM (kmem)
After:
100000000-1ffffffff : dax1.0
100000000-1ffffffff : System RAM (kmem)
The expectation is that this does not lead to a user visible regression
because the dax1.0 device is created in both instances.

The `COMEDI_RANGEINFO` ioctl does not work properly for subdevice
indices above 15. Currently, the only in-tree COMEDI drivers that
support more than 16 subdevices are the "8255" driver and the
"comedi_bond" driver. Making the ioctl work for subdevice indices up to
255 is achievable. It needs minor changes to the handling of the
`COMEDI_RANGEINFO` and `COMEDI_CHANINFO` ioctls that should be mostly
harmless to user-space, apart from making them less broken. Details
follow...
The `COMEDI_RANGEINFO` ioctl command gets the list of supported ranges
(usually with units of volts or milliamps) for a COMEDI subdevice or
channel. (Only some subdevices have per-channel range tables, indicated
by the `SDF_RANGETYPE` flag in the subdevice information.) It uses a
`range_type` value and a user-space pointer, both supplied by
user-space, but the `range_type` value should match what was obtained
using the `COMEDI_CHANINFO` ioctl (if the subdevice has per-channel
range tables) or `COMEDI_SUBDINFO` ioctl (if the subdevice uses a
single range table for all channels). Bits 15 to 0 of the `range_type`
value contain the length of the range table, which is the only part that
user-space should care about (so it can use a suitably sized buffer to
fetch the range table). Bits 23 to 16 store the channel index, which is
assumed to be no more than 255 if the subdevice has per-channel range
tables, and is set to 0 if the subdevice has a single range table. For
`range_type` values produced by the `COMEDI_SUBDINFO` ioctl, bits 31 to
24 contain the subdevice index, which is assumed to be no more than 255.
But for `range_type` values produced by the `COMEDI_CHANINFO` ioctl,
bits 27 to 24 contain the subdevice index, which is assumed to be no
more than 15, and bits 31 to 28 contain the COMEDI device's minor device
number for some unknown reason lost in the mists of time. The
`COMEDI_RANGEINFO` ioctl extract the length from bits 15 to 0 of the
user-supplied `range_type` value, extracts the channel index from bits
23 to 16 (only used if the subdevice has per-channel range tables),
extracts the subdevice index from bits 27 to 24, and ignores bits 31 to
28. So for subdevice indices 16 to 255, the `COMEDI_SUBDINFO` or
`COMEDI_CHANINFO` ioctl will report a `range_type` value that doesn't
work with the `COMEDI_RANGEINFO` ioctl. It will either get the range
table for the subdevice index modulo 16, or will fail with `-EINVAL`.
To fix this, always use bits 31 to 24 of the `range_type` value to hold
the subdevice index (assumed to be no more than 255). This affects the
`COMEDI_CHANINFO` and `COMEDI_RANGEINFO` ioctls. There should not be
anything in user-space that depends on the old, broken usage, although
it may now see different values in bits 31 to 28 of the `range_type`
values reported by the `COMEDI_CHANINFO` ioctl for subdevices that have
per-channel subdevices. User-space should not be trying to decode bits
31 to 16 of the `range_type` values anyway.

When rtsx_pci suspends, the card reader hardware powers off but the sdmmc
driver's prev_power_state remains as MMC_POWER_ON. This causes sd_power_on
to skip reinitialization on the next I/O request, leading to DMA transfer
timeouts and errors on resume 20% of the time.
Add a power_off slot callback so the PCR can notify the sdmmc driver
during suspend. The sdmmc driver resets prev_power_state, and sd_request
checks this to reinitialize the card before the next I/O.

The problem is that with randomize_va_space == 0

arch_get_unmapped_area_topdown() doesn't take TIF_ADDR32 into account and
in_32bit_syscall() is false, this leads to info.high_limit > TASK_SIZE.
vm_unmapped_area() happily returns the high address > TASK_SIZE and then
get_unmapped_area() returns -ENOMEM after the "if (addr > TASK_SIZE - len)"
check.
handle_swbp() doesn't report this failure (probably it should) and silently
restarts the probed insn. Endless loop.
I think that the right fix should change the x86 get_unmapped_area() paths
to rely on TIF_ADDR32 rather than in_32bit_syscall(). Note also that if
CONFIG_X86_X32_ABI=y, in_x32_syscall() falsely returns true in this case
because ->orig_ax = -1.
But we need a simple fix for -stable, so this patch just sets TS_COMPAT if
the probed task is 32-bit to make in_ia32_syscall() true.

Some resources can be removed asynchronously, for example, resources
provided by a hot-pluggable device like USB. When holding a reference
to such a resource, it's possible for the resource to be removed and
its memory freed, leading to use-after-free errors on subsequent access.
The "revocable" mechanism addresses this by establishing a weak reference
to a resource that might be freed at any time. It allows a resource
consumer to safely attempt to access the resource, guaranteeing that the
access is valid for the duration of its use, or it fails safely if the
resource has already been revoked.
The implementation uses a provider/consumer model built on Sleepable
RCU (SRCU) to guarantee safe memory access:
- A resource provider, such as a driver for a hot-pluggable device,
allocates a struct revocable_provider and initializes it with a pointer
to the resource.
- A resource consumer that wants to access the resource allocates a
struct revocable which acts as a handle containing a reference to the
provider.
- To access the resource, the consumer uses revocable_try_access().
This function enters an SRCU read-side critical section and returns
the pointer to the resource. If the provider has already freed the
resource, it returns NULL. After use, the consumer calls
revocable_withdraw_access() to exit the SRCU critical section. The
REVOCABLE_TRY_ACCESS_WITH() and REVOCABLE_TRY_ACCESS_SCOPED() are
convenient helpers for doing that.
- When the provider needs to remove the resource, it calls
revocable_provider_revoke(). This function sets the internal resource
pointer to NULL and then calls synchronize_srcu() to wait for all
current readers to finish before the resource can be completely torn
down.

Originally, when a queue was requested, it could only be configured
with the default algorithm type of 0. Now, when multiple tfms use
the same queue, the queue must be selected based on its attributes
to meet the requirements of tfm tasks. So the algorithm type
attribute of queue need to be distinguished. Just like a queue used
for compression in ZIP cannot be used for decompression tasks.

for callback
When multiple tfm use a same qp, the backlog data should be managed
centrally by the qp, rather than in the qp_ctx of each req.
Additionally, since SEC_BD_TYPE1 and SEC_BD_TYPE2 cannot use the
tag of the sqe to carry the virtual address of the req, the sent
sqe is stored in the qp. This allows the callback function to get
the req address. To handle the differences between hardware types,
the callback functions are split into two separate implementations.

Currently, the driver's device private data is allocated and initialized
from driver core code called from bus abstractions after the driver's
probe() callback returned the corresponding initializer.
Similarly, the driver's device private data is dropped within the
remove() callback of bus abstractions after calling the remove()
callback of the corresponding driver.
However, commit 6f61a2637abe ("rust: device: introduce
Device::drvdata()") introduced an accessor for the driver's device
private data for a Device<Bound>, i.e. a device that is currently bound
to a driver.
Obviously, this is in conflict with dropping the driver's device private
data in remove(), since a device can not be considered to be fully
unbound after remove() has finished:
We also have to consider registrations guarded by devres - such as IRQ
or class device registrations - which are torn down after remove() in
devres_release_all().
Thus, it can happen that, for instance, a class device or IRQ callback
still calls Device::drvdata(), which then runs concurrently to remove()
(which sets dev->driver_data to NULL and drops the driver's device
private data), before devres_release_all() started to tear down the
corresponding registration. This is because devres guarded registrations
can, as expected, access the corresponding Device<Bound> that defines
their scope.
In C it simply is the driver's responsibility to ensure that its device
private data is freed after e.g. an IRQ registration is unregistered.
Typically, C drivers achieve this by allocating their device private data
with e.g. devm_kzalloc() before doing anything else, i.e. before e.g.
registering an IRQ with devm_request_threaded_irq(), relying on the
reverse order cleanup of devres.
Technically, we could do something similar in Rust. However, the
resulting code would be pretty messy:
In Rust we have to differentiate between allocated but uninitialized
memory and initialized memory in the type system. Thus, we would need to
somehow keep track of whether the driver's device private data object
has been initialized (i.e. probe() was successful and returned a valid
initializer for this memory) and conditionally call the destructor of
the corresponding object when it is freed.
This is because we'd need to allocate and register the memory of the
driver's device private data *before* it is initialized by the
initializer returned by the driver's probe() callback, because the
driver could already register devres guarded registrations within
probe() outside of the driver's device private data initializer.
Luckily there is a much simpler solution: Instead of dropping the
driver's device private data at the end of remove(), we just drop it
after the device has been fully unbound, i.e. after all devres callbacks
have been processed.
For this, we introduce a new post_unbind() callback private to the
driver-core, i.e. the callback is neither exposed to drivers, nor to bus
abstractions.
This way, the driver-core code can simply continue to conditionally
allocate the memory for the driver's device private data when the
driver's initializer is returned from probe() - no change needed - and
drop it when the driver-core code receives the post_unbind() callback.

Mahe reported issue with bpf_override_return helper not working when

The problem is that on arm we use alternate storage for pt_regs object
that is passed to bpf_prog_run and if any register is changed (which
is the case of bpf_override_return) it's not propagated back to actual
pt_regs object.

Move the SPARC64 AES assembly code into lib/crypto/, wire the key
expansion and single-block en/decryption functions up to the AES library
API, and remove the "aes-sparc64" crypto_cipher algorithm.
The result is that both the AES library and crypto_cipher APIs use the
SPARC64 AES opcodes, whereas previously only crypto_cipher did (and it
wasn't enabled by default, which this commit fixes as well).
Note that some of the functions in the SPARC64 AES assembly code are
still used by the AES mode implementations in
arch/sparc/crypto/aes_glue.c. For now, just export these functions.
These exports will go away once the AES mode implementations are
migrated to the library as well. (Trying to split up the assembly file
seemed like much more trouble than it would be worth.)

Currently the post-populate callbacks handle copying source pages into
private GPA ranges backed by guest_memfd, where kvm_gmem_populate()
acquires the filemap invalidate lock, then calls a post-populate
callback which may issue a get_user_pages() on the source pages prior to
copying them into the private GPA (e.g. TDX).
This will not be compatible with in-place conversion, where the
userspace page fault path will attempt to acquire the filemap invalidate
lock while holding the mm->mmap_lock, leading to a potential ABBA
deadlock.
Address this by hoisting the GUP above the filemap invalidate lock so
that these page faults path can be taken early, prior to acquiring the
filemap invalidate lock.
It's not currently clear whether this issue is reachable with the
current implementation of guest_memfd, which doesn't support in-place
conversion, however it does provide a consistent mechanism to provide
stable source/target PFNs to callbacks rather than punting to
vendor-specific code, which allows for more commonality across
architectures, which may be worthwhile even without in-place conversion.
As part of this change, also begin enforcing that the 'src' argument to
kvm_gmem_populate() must be page-aligned, as this greatly reduces the
complexity around how the post-populate callbacks are implemented, and
since no current in-tree users support using a non-page-aligned 'src'
argument.

kvm_gmem_populate(), and the associated post-populate callbacks, have
some limited support for dealing with guests backed by hugepages by
passing the order information along to each post-populate callback and
iterating through the pages passed to kvm_gmem_populate() in
hugepage-chunks.
However, guest_memfd doesn't yet support hugepages, and in most cases
additional changes in the kvm_gmem_populate() path would also be needed
to actually allow for this functionality.
This makes the existing code unnecessarily complex, and makes changes
difficult to work through upstream due to theoretical impacts on
hugepage support that can't be considered properly without an actual
hugepage implementation to reference. So for now, remove what's there
so changes for things like in-place conversion can be
implemented/reviewed more efficiently.
