linux/usb/pd.h has a bunch of timers for which the Type-C spec defines
a range of values. These values have to be tuned based on the latency
observed in a specific architecture. However, linux opensource sets
them to a specific value without providing a mechanism to set board
specific values. While a generic way is figured out, a vendor hook
is needed in the interim.
For instance, tCCDebounce can have a value between 100msec - 200msec.

(cherry picked from commit 08879ea0d6)
This change fixes a bug where inbound packets to nested IPsec tunnels
fails to pass policy checks due to the inner tunnel's policy checks
not having a reference to the outer policy/template. This causes the
policy check to fail, since the first entries in the secpath correlate
to the outer tunnel, while the templates being verified are for the
inner tunnel.
In order to ensure that the appropriate policy and template context is
searchable, the policy checks must be done incrementally between each
decryption step. As such, this marks secpath entries as having been
successfully matched, skipping them (treating as optional) on subsequent
policy checks
By skipping the immediate error return in the case where the secpath
entry had previously been validated, this change allows secpath entries
that matched a policy/template previously, while still requiring that
each searched template find a match in the secpath.
For security:
- All templates must have matching secpath entries
- Unchanged by current patch; templates that do not match any secpath
entry still return -1. This patch simply allows skipping earlier
blocks of verified secpath entries
- All entries (except trailing transport mode entries) must have a
matching template
- Unvalidated entries, including transport-mode entries still return
the errored index if it does not match the correct template.

(cherry picked from commit 970e02667c)
This patch adds POSIX_FADV_NOREUSE to vma_has_recency() so that the LRU
algorithm can ignore access to mapped files marked by this flag.
The advantages of POSIX_FADV_NOREUSE are:
1. Unlike MADV_SEQUENTIAL and MADV_RANDOM, it does not alter the
default readahead behavior.
2. Unlike MADV_SEQUENTIAL and MADV_RANDOM, it does not split VMAs and
therefore does not take mmap_lock.
3. Unlike MADV_COLD, setting it has a negligible cost, regardless of
how many pages it affects.
Its limitations are:
1. Like POSIX_FADV_RANDOM and POSIX_FADV_SEQUENTIAL, it currently does
not support range. IOW, its scope is the entire file.
2. It currently does not ignore access through file descriptors.
Specifically, for the active/inactive LRU, given a file page shared
by two users and one of them having set POSIX_FADV_NOREUSE on the
file, this page will be activated upon the second user accessing
it. This corner case can be covered by checking POSIX_FADV_NOREUSE
before calling folio_mark_accessed() on the read path. But it is
considered not worth the effort.
There have been a few attempts to support POSIX_FADV_NOREUSE, e.g., [1].
This time the goal is to fill a niche: a few desktop applications, e.g.,
large file transferring and video encoding/decoding, want fast file
streaming with mmap() rather than direct IO. Among those applications, an
SVT-AV1 regression was reported when running with MGLRU [2]. The
following test can reproduce that regression.
kb=$(awk '/MemTotal/ { print $2 }' /proc/meminfo)
kb=$((kb - 8*1024*1024))
modprobe brd rd_nr=1 rd_size=$kb

which makes it on par with the active/inactive LRU.

Add vma_has_recency() to indicate whether a VMA may exhibit temporal
locality that the LRU algorithm relies on.
This function returns false for VMAs marked by VM_SEQ_READ or
VM_RAND_READ. While the former flag indicates linear access, i.e., a
special case of spatial locality, both flags indicate a lack of temporal
locality, i.e., the reuse of an area within a relatively small duration.
"Recency" is chosen over "locality" to avoid confusion between temporal
and spatial localities.
Before this patch, the active/inactive LRU only ignored the accessed bit
from VMAs marked by VM_SEQ_READ. After this patch, the active/inactive
LRU and MGLRU share the same logic: they both ignore the accessed bit if
vma_has_recency() returns false.
For the active/inactive LRU, the following fio test showed a [6, 8]%
increase in IOPS when randomly accessing mapped files under memory
pressure.
kb=$(awk '/MemTotal/ { print $2 }' /proc/meminfo)
kb=$((kb - 8*1024*1024))

This adds some mechanisms around the iommu_domain so that the I/O page
fault handling framework could route a page fault to the domain and
call the fault handler from it.
Add pointers to the page fault handler and its private data in struct
iommu_domain. The fault handler will be called with the private data
as a parameter once a page fault is routed to the domain. Any kernel
component which owns an iommu domain could install handler and its
private parameter so that the page fault could be further routed and
handled.
This also prepares the SVA implementation to be the first consumer of
the per-domain page fault handling model. The I/O page fault handler
for SVA is copied to the SVA file with mmget_not_zero() added before
mmap_read_lock().

The existing iommu SVA interfaces are implemented by calling the SVA
specific iommu ops provided by the IOMMU drivers. There's no need for
any SVA specific ops in iommu_ops vector anymore as we can achieve
this through the generic attach/detach_dev_pasid domain ops.
This refactors the IOMMU SVA interfaces implementation by using the
iommu_attach/detach_device_pasid interfaces and align them with the
concept of the SVA iommu domain. Put the new SVA code in the SVA
related file in order to make it self-contained.

The SVA iommu_domain represents a hardware pagetable that the IOMMU
hardware could use for SVA translation. This adds some infrastructures
to support SVA domain in the iommu core. It includes:
- Extend the iommu_domain to support a new IOMMU_DOMAIN_SVA domain
type. The IOMMU drivers that support allocation of the SVA domain
should provide its own SVA domain specific iommu_domain_ops.
- Add a helper to allocate an SVA domain. The iommu_domain_free()
is still used to free an SVA domain.
The report_iommu_fault() should be replaced by the new
iommu_report_device_fault(). Leave the existing fault handler with the
existing users and the newly added SVA members excludes it.

Attaching an IOMMU domain to a PASID of a device is a generic operation
for modern IOMMU drivers which support PASID-granular DMA address
translation. Currently visible usage scenarios include (but not limited):
- SVA (Shared Virtual Address)
- kernel DMA with PASID
- hardware-assist mediated device
This adds the set_dev_pasid domain ops for setting the domain onto a
PASID of a device and remove_dev_pasid iommu ops for removing any setup
on a PASID of device. This also adds interfaces for device drivers to
attach/detach/retrieve a domain for a PASID of a device.
If multiple devices share a single group, it's fine as long the fabric
always routes every TLP marked with a PASID to the host bridge and only
the host bridge. For example, ACS achieves this universally and has been
checked when pci_enable_pasid() is called. As we can't reliably tell the
source apart in a group, all the devices in a group have to be considered
as the same source, and mapped to the same PASID table.
The DMA ownership is about the whole device (more precisely, iommu group),
including the RID and PASIDs. When the ownership is converted, the pasid
array must be empty. This also adds necessary checks in the DMA ownership
interfaces.

The current kernel DMA with PASID support is based on the SVA with a flag
SVM_FLAG_SUPERVISOR_MODE. The IOMMU driver binds the kernel memory address
space to a PASID of the device. The device driver programs the device with
kernel virtual address (KVA) for DMA access. There have been security and
functional issues with this approach:
- The lack of IOTLB synchronization upon kernel page table updates.
(vmalloc, module/BPF loading, CONFIG_DEBUG_PAGEALLOC etc.)
- Other than slight more protection, using kernel virtual address (KVA)
has little advantage over physical address. There are also no use
cases yet where DMA engines need kernel virtual addresses for in-kernel
DMA.
This removes SVM_FLAG_SUPERVISOR_MODE support from the IOMMU interface.
The device drivers are suggested to handle kernel DMA with PASID through
the kernel DMA APIs.
The drvdata parameter in iommu_sva_bind_device() and all callbacks is not
needed anymore. Cleanup them as well.

Use this field to keep the number of supported PASIDs that an IOMMU
hardware is able to support. This is a generic attribute of an IOMMU
and lifting it into the per-IOMMU device structure makes it possible
to allocate a PASID for device without calls into the IOMMU drivers.
Any iommu driver that supports PASID related features should set this
field before enabling them on the devices.
In the Intel IOMMU driver, intel_iommu_sm is moved to CONFIG_INTEL_IOMMU
enclave so that the pasid_supported() helper could be used in dmar.c
without compilation errors.

'struct fscrypt_operations' shouldn't really be part of the KMI, as
there's no reason for loadable modules to use it. However, due to the
way MODVERSIONS calculates symbol CRCs by recursively dereferencing
structures, changes to 'struct fscrypt_operations' affect the CRCs of
KMI functions exported from certain core kernel files such as
fs/dcache.c. That brings it in-scope for the KMI freeze.
Therefore, add some reserved fields to this struct for LTS updates.

commit 9d2789ac9d upstream.
io_uring_cmd_done() currently assumes that the uring_lock is held
when invoked, and while it generally is, this is not guaranteed.
Pass in the issue_flags associated with it, so that we have
IO_URING_F_UNLOCKED available to be able to lock the CQ ring

restricted_memfd. Until then, it is in Android Common Kernel following
the GH_VM_ANDROID_LEND_USER_MEMORY patches.

Add support for lending memory via GH_VM_ANDROID_LEND_USER_MEM. Lending
memory makes it inaccessible to the host.
pKVM and Gunyah aim to converge to a common design based around
restricted_memfd in kernel.org, but the base restricted_memfd support is
not available yet. So, carry the support to lend memory as an Android
patch.

Add support for further vendor features of Gunyah. To probe the vendor
features, add auxiliary device and export gh_rm_call to all the vendor
features to make not-yet-upstreamed RM RPC calls.

Enable support for creating irqfds which can raise an interrupt on a
Gunyah virtual machine. irqfds are exposed to userspace as a Gunyah VM
function with the name "irqfd". If the VM devicetree is not configured
to create a doorbell with the corresponding label, userspace will still
be able to assert the eventfd but no interrupt will be raised on the
guest.

Gunyah allows host virtual machines to schedule guest virtual machines
and handle their MMIO accesses. vCPUs are presented to the host as a
Gunyah resource and represented to userspace as a Gunyah VM function.
Creating the vcpu VM function will create a file descriptor that:
- can run an ioctl: GH_VCPU_RUN to schedule the guest vCPU until the
next interrupt occurs on the host or when the guest vCPU can no
longer be run.
- can be mmap'd to share a gh_vcpu_run structure which can look up the
reason why GH_VCPU_RUN returned and provide return values for MMIO
access.

Some VM functions need to acquire Gunyah resources. For instance, Gunyah
vCPUs are exposed to the host as a resource. The Gunyah vCPU function
will register a resource ticket and be able to interact with the
hypervisor once the resource ticket is filled.
Resource tickets are the mechanism for functions to acquire ownership of
Gunyah resources. Gunyah functions can be created before the VM's
resources are created and made available to Linux. A resource ticket
identifies a type of resource and a label of a resource which the ticket
holder is interested in.
Resources are created by Gunyah as configured in the VM's devicetree
configuration. Gunyah doesn't process the label and that makes it
possible for userspace to create multiple resources with the same label.
Resource ticket owners need to be prepared for populate to be called
multiple times if userspace created multiple resources with the same
label.

Introduce a framework for Gunyah userspace to install VM functions. VM
functions are optional interfaces to the virtual machine. vCPUs,
ioeventfs, and irqfds are examples of such VM functions and are
implemented in subsequent patches.
A generic framework is implemented instead of individual ioctls to
create vCPUs, irqfds, etc., in order to simplify the VM manager core
implementation and allow dynamic loading of VM function modules.

When booting a Gunyah virtual machine, the host VM may gain capabilities
to interact with resources for the guest virtual machine. Examples of
such resources are vCPUs or message queues. To use those resources, we
need to translate the RM response into a gunyah_resource structure which
are useful to Linux drivers. Presently, Linux drivers need only to know
the type of resource, the capability ID, and an interrupt.
On ARM64 systems, the interrupt reported by Gunyah is the GIC interrupt
ID number and always a SPI.

Add remaining ioctls to support non-proxy VM boot:
- Gunyah Resource Manager uses the VM's devicetree to configure the
virtual machine. The location of the devicetree in the guest's
virtual memory can be declared via the SET_DTB_CONFIG ioctl.
- Trigger start of the virtual machine with VM_START ioctl.
