KVM/arm64 fixes for 7.2, take #3
- Fix a tiny buglet when propagating the deactivation of an interrupt
from a nested guest, which happened to trigger a gold plated CPU bug
on a particular implementation
- Fix a race between LPI unmapping and mapping, resulting in leaked
LPIs
- Make LPI mapping more robust on memory allocation failure
- Fix the handling of the EL2 tracing clock being disabled
- A couple of Sashiko-driven fixes for corner cases in the EL2 tracing
code
- Add missing sysreg tracepoint for the EL2 code
- Tidy-up the mutual exclusion of guest-memfd and MTE
- Update Fuad's email address to point to @linux.dev

KVM: s390: Fixes for 7.2
- several fixes for PCI passthru in s390 kvm
- fix a 7.2-rc regression in the adapter interrupt mapping code
|
|
FOLL_LONGTERM pinning fails for some memory types, such as file-backed
guest memory. As a result, kvm_s390_adapter_map() returns -EINVAL and
irqfd adapter registration fails even though interrupt delivery could
still work via the existing non-atomic path.
When FOLL_LONGTERM pinning fails, verify that the page is accessible
using a short-term pin instead. If the short-term pin succeeds, unpin
the page and add a map entry with pinned=false to preserve MAP/UNMAP
symmetry. The non-atomic irqfd path already performs short-term pinning
for interrupt delivery, so this restores the previous behavior for
memory that cannot be pinned long-term.
get_map_info() is updated to return NULL for unpinned entries so that
the atomic irqfd fast path falls back to the non-atomic path.
kvm_s390_adapter_unmap() and kvm_s390_unmap_all_adapters() skip dirty
marking and unpin for unpinned entries.
Update Documentation/virt/kvm/devices/s390_flic.rst to reflect the
new MAP/UNMAP behavior.

The user cannot use MTE on VMAs created by mapping a guest_memfd file,
as arch_calc_vm_flag_bits() does not set VM_MTE_ALLOWED.
When creating a guest_memfd backed memslot,
kvm_arch_prepare_memory_region() rejects the memslot if MTE is enabled for
the VM and if guest_memfd has been mapped in a VMA that intersects the
memslot.
However, the documentation for KVM_SET_USER_MEMORY_REGION2 explicitly
states that the only condition for userspace_addr is for it to be a legal
userspace address, but the mapping is not required to be valid nor
populated at memslot creation.
If userspace sets userspace_addr to an address that hasn't been mapped, or
if userspace_addr belongs to a VMA that isn't backed by the guest_memfd
file, or if the VMA doesn't intersect the memslot, memslot creation is
successful and KVM ends up with a VM with MTE and guest_memfd-backed
memslots.
The same happens if the order is reversed: when userspace enables MTE, KVM
does not check if memslots backed by guest_memfd are already present.
Fix both issues by rejecting guest_memfd-backed memslots when MTE is
enabled, and by rejecting MTE when guest_memfd-backed memslots are already
present.
Fixes: 32e200bd6e44 ("KVM: arm64: Enable support for guest_memfd backed memory")

In the nested state, the physical interrupt has already been
deactivated through the HW bit in the LR. The extra deactivation
would be harmless but can hit an errata case on AmpereOne, so
avoid it here.
On AmpereOne, deactivating a physical interrupt through
ICC_DIR_EL1 or ICC_EOIR1_EL1 (depending on EOImode) which is not
active, but is the highest priority pending interrupt causes the
cpu to lose the interrupt pending state and also prevents the
delivery of future interrupts.

A number of IFLA_BRPORT_* attributes are documented in the rt-link spec
as having the "flag" type, i.e. a payload-less NLA_FLAG attribute whose
meaning is presence-only. This does not match the kernel, which emits
these attributes with nla_put_u8() and validates them as NLA_U8 in
br_port_policy[]. The values are not mere presence flags but carry a u8
payload (0/1).
Convert these bridge port attributes from "flag" to "u8" so the spec
reflects the actual wire format.

A handful of vendor-extension entries indent continuation lines with a
tab character, while the rest of hwprobe.rst uses spaces. In addition,
many list items align their continuation lines under the 'm' of
':c:macro:' (column 7) rather than under the item text (column 4), so
the file mixes several indentation styles.
Replace the tabs with spaces and align every list item's continuation
lines under the item text, giving the whole file one consistent style.
Whitespace-only change, no functional change.
[Guodong: extend from tabs->spaces to normalizing all continuation-line
indentation across the file]

The io.stat section says that enabling the io.latency controller exposes
the depth, avg_lat and win stats in addition to the normal ones. However,
these io.latency-specific stats are debug stats and are only emitted when
the blkcg_debug_stats module parameter is enabled, which is disabled by
default.
Make this explicit so users do not expect these fields to appear in
io.stat by default, and qualify the usage text that suggests using
avg_lat to pick an io.latency target.

runtime modified flags. These were noted across several Sashiko
reviews as pre-existing issues (Alex Williamson)
- Fix runtime PM inconsistency where the vfio-pci driver module_init
could modify the idle PM policy of existing devices through globals
managed in vfio-pci-core, leading to unbalanced runtime PM
operations (Alex Williamson)
- Restore mutability of writable vfio-pci module options by further
pulling policy globals out of vfio-pci-core, to instead be latched
per device at device init. Provide visibility of the per device
latched values through debugfs (Alex Williamson)
- Fix missing VGA arbiter uninit callback in unwind path (Alex
Williamson)
- Reorder device debugfs removal before device_del() to avoid gap

an RZ/N1 entry which was not in the original txt-file. It doesn't follow
the usual "<soc entry>, <soc family entry>" style for Renesas SoCs which
was properly added later with commit 029d32a892a8 ("spi: dw-apb-ssi:

bogus entry was overlooked and is finally done now.

The nointxmask and disable_idle_d3 module parameters remain writable,
but vfio-pci now latches their values into each device at init. Once a
device is registered, changing the module parameter only affects future
devices, leaving no direct way to confirm the effective policy for an
existing device.
Add a pci debugfs directory under the VFIO device debugfs root and
report the per-device nointxmask and disable_idle_d3 values. These are
read-only debugfs views and use the same Y/N bool output convention as
the module parameters.
Read-only vfio-pci parameters, such as disable_vga, are not exposed here
because they cannot drift from the latched device value, therefore the
existing module parameter exposure via sysfs is sufficient.
Note that while only vfio-pci currently provides these options, the
implementation is in vfio-pci-core and therefore properly reflects the
device policy in the core, regardless of driver.
