Currently, gunyah_cma_release() unconditionally releases the entire
CMA memory region of the VM, regardless of how much was actually mapped.
This can lead to issues if AVF clients lauches VM wherein the memory
mapped is less than the size of the VM's CMA region(max size).
To address this:
- A new mapped_size field is added to struct gunyah_cma to track the
actual size mapped.
- gunyah_cma_alloc() sets this field and logs a debug message if the
mapped size is less than the max size.
- gunyah_cma_release() now uses mapped_size to determine how much memory
to release.

Check if the file pointer of the guest_mem_fd is valid or not.
Otherwise, there can be a NULL pointer dereference.

The gunyah_vm_clean_resources() function was freeing resources without
removing them from the ghvm->resources list, leaving dangling pointers
that could lead to use-after-free.
Fix this by removing each resource from the list before freeing it to
ensure lists are empty after cleanup.

One process boots up SVM, the CMA memory is allocated and used by SVM.
If another process try to boot up VM again, will allocate fail and
release this CMA memory region. It will cause kernel panic when one
process allocates memory from this CMA memory region due to not do
relciam parcel for this memory. Fix this issue by return a error in
gunyah_cma_create_mem_fd to avoid gunyah_cma_release is called when
the CMA memory region is already allocated by other process.

Add Android kernel vendor hooks before and after VM demand paging to
enable calls to vendor modules for memory protection. This enhancement
ensures that memory protection mechanisms are properly invoked during
the demand paging process, improving the overall security and
stability of the system.
This feature is particularly important for systems that rely on
multiple IOMMU components to manage memory protection, ensuring that
all necessary preparation are properly applied during the demand
paging process.

The ADDRSPACE_VMMIO_CONFIGURE hypercall might be implemented but does
not allow the guest to nominate VMMIO regions. The current
implementation bails out only if the hypercall is not implemented.
If the firmware implements the hypercall but returns an insufficient
permission error, it could cause ioremap() to fail on the guest.
Fix this by checking against GUNYAH_ERROR_CSPACE_INSUF_RIGHTS error
code.

commit fba4ceaa242d2bdf4c04b77bda41d32d02d3925d upstream.
Unlike sysfs, the lifetime of configfs objects is controlled by
userspace. There is no mechanism for the kernel to find and delete all
created config-items. Instead, the configfs-tsm-report mechanism has an
expectation that tsm_unregister() can happen at any time and cause
established config-item access to start failing.
That expectation is not fully satisfied. While tsm_report_read(),
tsm_report_{is,is_bin}_visible(), and tsm_report_make_item() safely fail
if tsm_ops have been unregistered, tsm_report_privlevel_store()
tsm_report_provider_show() fail to check for ops registration. Add the
missing checks for tsm_ops having been removed.
Now, in supporting the ability for tsm_unregister() to always succeed,
it leaves the problem of what to do with lingering config-items. The
expectation is that the admin that arranges for the ->remove() (unbind)
of the ${tsm_arch}-guest driver is also responsible for deletion of all
open config-items. Until that deletion happens, ->probe() (reload /
bind) of the ${tsm_arch}-guest driver fails.
This allows for emergency shutdown / revocation of attestation
interfaces, and requires coordinated restart.

PSCI_SYSTEM_RESET is a valid return value of the vcpu_run
hypercall. As kernel doesn't have any special handling of this
case, treat it as a generic SYSTEM_OFF and let the VMM take the
appropriate action as the vcpu_run structure will have the

This is a CMA allocator for VMs which need their memory to be backed by

obtain an fd to the file created which represents the VM's memory backed

Add a Gunyah protected guest driver. A Gunyah protected guest needs to
be hypervisor-aware to relinquish pages to the host/owner for
virtio-balloon. In the Android Virtualization Framework model, the
host/owner VM, not the hypervisor, owns the virtio devices. The
hypervisor is unaware about the virtio device and thus the guest needs
to inform the hypervisor that the host can access guest-private memory.

Gunyah (the hypervisor) currently requires a guest to use devicetree to
provide capability IDs and interrupts to communincation with the
resource manager. A new mechanism, address space info area, is
introduced to discover the same information without using devicetree.
Now that we have no devicetree, we don't have a platform device, so the
RM "driver" is converted to a pure kernel module.
Backwards compatability with older Gunyah without the address space info
area is maintained by probing the devicetree directly without using the
platform device.

Now that Gunyah modules can be probed without devicetree, there is no
reason to bind/populate the gunyah-hypervisor node, even if it exists.
Convert the probe function, which checked if we were running under
Gunyah and tested for the info_area, into a regular initcall.
core_initcall() used because Gunyah-aware protected guest needs to
initialize early for virtio-balloon/free page reporting.

commit 819cec1dc47cdeac8f5dd6ba81c1dbee2a68c3bb upstream.
In the "pmcmd_ioctl" function, three memory objects allocated by
kmalloc are initialized by "hcall_get_cpu_state", which are then
copied to user space. The initializer is indeed implemented in
"acrn_hypercall2" (arch/x86/include/asm/acrn.h). There is a risk of
information leakage due to uninitialized bytes.

Currently pkvm_granule alignment is enforced for the start address of
the ioremap hook. This is a problem as this address doesn't have to be
aligned at all. At the same time, the size of the ioremap isn't verified
and we can simply overshoot the MMIO guard original request.
MMIO guard is solely here to indicate to the hypervisor where are the
MMIO regions. If we validate the RAM is aligned with the pkvm_granule,
we can safely overshoot the MMIO guard.

gunyah_gup_share_parcel() has an in/out parameter which indicates the
number of pages requested to be shared in the mem parcel. We were not
returning the number of pages actually shared in the mem parcel and this
caused THPs to be undercounted. Later, when converting the parcel to
demand paged (gunyah_vm_parcel_to_paged), we hit the BUG_ON on line 55
due to the undercount. Fix the BUG_ON by correctly counting the *nr
return value.
Fixes: due to the undercount. Fix the BUG_ON by correctly counting the
*nr return value due to the undercount. Fix the BUG_ON by correctly
counting the *nr return value.

gunyah_gup_reclaim_parcel incorrectly used folio_put() to drop the
refcount for the pinned page. This leaves the folio pincount elevated.
If the VM initialization fails in Gunyah and Linux needs to reclaim the
mem parcel, mm will complain that the pincount was higher than refcount.
This reclaim path is not normally used, as memory backed by parcels is
reclaimed in the demand paging path if the VM starts successfully.

gunyah_gup_share_parcel incorrectly calculates n_mem_entries and places
items into the mem_entries array. To save number of bytes sent to RM, we
describe only folios -- not individual pages. We incorrectly filled the
mem_entries array with some entries as 0's. Track insertion into the
mem_entries array with new indexer: entries.
