- The 2 patch series "pid: make sub-init creation retryable" from Oleg
Nesterov increases the robustness of our creation of init in a new
namespace. By clearing away some historical cruft which is no longer
needed. Also some documentation fixups are provided.
- The 2 patch series "selftests/fchmodat2: Error handling and general"
from Mark Brown has a fixup and a cleanup for the fchmodat2() syscall
selftest.
- The 3 patch series "lib: polynomial: Move to math/ and clean up" from
Andy Shevchenko does as advertised.
- The 3 patch series "hung_task: Provide runtime reset interface for
hung task detector" from Aaron Tomlin gives administrators the ability
to zero out /proc/sys/kernel/hung_task_detect_count.
- The 2 patch series "tools/getdelays: use the static UAPI headers from
tools/include/uapi" from Thomas Weißschuh teaches getdelays to use the
in-kernel UAPI headers rather than the system-provided ones.
- The 5 patch series "watchdog/hardlockup: Improvements to hardlockup"
from Mayank Rungta provides several cleanups and fixups to the
hardlockup detector code and its documentation.
- The 2 patch series "lib/bch: fix undefined behavior from signed
left-shifts" from Josh Law provides a couple of small/theoretical fixes
in the bch code.
- The 2 patch series "ocfs2/dlm: fix two bugs in dlm_match_regions()"
from Junrui Luo does what is claims.
- The 27 patch series "cleanup the RAID5 XOR library" from Christoph
Hellwig is a quite far-reaching cleanup to this code. I can't do better
than to quote Christoph:
The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography and
not using the crypto API, with the generic implementations sitting in
include/asm-generic and the arch implementations sitting in an asm/
header in theory. The latter doesn't work for many cases, so
architectures often build the code directly into the core kernel, or
create another module for the architecture code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric Biggers
has done for the CRC and crypto libraries later. After that it
changes to better calling conventions that allow for smarter
architecture implementations (although none is contained here yet),
and uses static_call to avoid indirection function call overhead.
- The 2 patch series "lib/list_sort: Clean up list_sort() scheduling
workarounds" from Kuan-Wei Chiu cleans up this library code by removing
a hacky thing which was added for UBIFS, which UBIFS doesn't actually
need.
- The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian
Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests
for the now-fixed bugs and fixes a leak in the test itself.
- The 3 patch series "kdump: Enable LUKS-encrypted dump target support
in ARM64 and PowerPC" from Coiby Xu eenables support of the
LUKS-encrypted device dump target on arm64 and powerpc.
- The 4 patch series "ocfs2: consolidate extent list validation into
block read callbacks" from Joseph Qi addresses ocfs2's validation of
extent list fields - cleanup, simplification, robustness. (Kernel test

of: unittest: fix use-after-free in testdrv_probe()
The function testdrv_probe() retrieves the device_node from the PCI
device, applies an overlay, and then immediately calls of_node_put(dn).
This releases the reference held by the PCI core, potentially freeing
the node if the reference count drops to zero. Later, the same freed
pointer 'dn' is passed to of_platform_default_populate(), leading to a
use-after-free.
The reference to pdev->dev.of_node is owned by the device model and
should not be released by the driver. Remove the erroneous of_node_put()
to prevent premature freeing.

of: unittest: fix use-after-free in of_unittest_changeset()
The variable 'parent' is assigned the value of 'nchangeset' earlier in the
function, meaning both point to the same struct device_node. The call to
of_node_put(nchangeset) can decrement the reference count to zero and
free the node if there are no other holders. After that, the code still
uses 'parent' to check for the presence of a property and to read a
string property, leading to a use-after-free.
Fix this by moving the of_node_put() call after the last access to
'parent', avoiding the UAF.

drivers/of: fdt: validate flat DT string properties before string use
Firmware-supplied flat DT properties are raw byte sequences. Several early FDT helpers fetch properties such as status, model, compatible, and device_type and then use them as C strings with strcmp(), strlen(), or pr_info() without first proving that the property is NUL-terminated within its declared length. Use fdt_stringlist_get() for these string properties instead. That preserves the existing behavior for valid DTBs while rejecting malformed unterminated properties before they are passed to C string helpers.

drivers/of: fdt: validate stdout-path properties before parsing them
early_init_dt_scan_chosen_stdout() fetches stdout-path and linux,stdout-path directly from the flat DT and immediately passes the result to strchrnul(). Flat DT properties are raw firmware-supplied byte sequences, and this path does not prove that either property is NUL-terminated within its declared bounds. Use fdt_stringlist_get() so malformed unterminated stdout-path properties are rejected before the local parser walks them as C strings.

of: property: Allow fw_devlink device-tree on x86
PCI drivers can use a device-tree overlay to describe the hardware available on the PCI board. This is the case, for instance, of the LAN966x PCI device driver. Adding some more nodes in the device-tree overlay adds some more consumer/supplier relationship between devices instantiated from this overlay. Those fw_node consumer/supplier relationships are handled by fw_devlink and are created based on the device-tree parsing done by the of_fwnode_add_links() function. Those consumer/supplier links are needed in order to ensure a correct PM runtime management and a correct removal order between devices. For instance, without those links a supplier can be removed before its consumers is removed leading to all kind of issue if this consumer still want the use the already removed supplier. The support for the usage of an overlay from a PCI driver has been added on x86 systems in commit |

arm64,ppc64le/kdump: pass dm-crypt keys to kdump kernel
CONFIG_CRASH_DM_CRYPT has been introduced to support LUKS-encrypted device dump target by addressing two challenges [1], - Kdump kernel may not be able to decrypt the LUKS partition. For some machines, a system administrator may not have a chance to enter the password to decrypt the device in kdump initramfs after the 1st kernel crashes - LUKS2 by default use the memory-hard Argon2 key derivation function which is quite memory-consuming compared to the limited memory reserved for kdump. To also enable this feature for ARM64 and PowerPC, the missing piece is to let the kdump kernel know where to find the dm-crypt keys which are randomly stored in memory reserved for kdump. Introduce a new device tree property dmcryptkeys [2] as similar to elfcorehdr to pass the memory address of the stored info of dm-crypt keys to the kdump kernel. Since this property is only needed by the kdump kernel, it won't be exposed to userspace.

device property: Make modifications of fwnode "flags" thread safe
In various places in the kernel, we modify the fwnode "flags" member
by doing either:
fwnode->flags |= SOME_FLAG;
fwnode->flags &= ~SOME_FLAG;
This type of modification is not thread-safe. If two threads are both
mucking with the flags at the same time then one can clobber the
other.
While flags are often modified while under the "fwnode_link_lock",
this is not universally true.
Create some accessor functions for setting, clearing, and testing the
FWNODE flags and move all users to these accessor functions. New
accessor functions use set_bit() and clear_bit(), which are
thread-safe.

of: reserved_mem: rework fdt_init_reserved_mem_node()
Move the content of fdt_reserved_mem_save_node() to fdt_init_reserved_mem_node() function. Initialization is no longer performed in two steps as it was initially, so fdt_reserved_mem_save_node() name is a bit misleading and that function now performs full initialization of the reserved memory region. This also fixes the problem of keeping pointers to the regions, which failed to initialize, what might cause issues when such region is assigned to the device.

of: Add of_machine_get_match() helper
Currently, there are two helpers to match the root compatible value
against an of_device_id array:
- of_machine_device_match() returns true if a match is found,
- of_machine_get_match_data() returns the match data if a match is
found.
However, there is no helper that returns the actual of_device_id
structure corresponding to the match, leading to code duplication in
various drivers.
Fix this by reworking of_machine_device_match() to return the actual
match structure, and renaming it to of_machine_get_match().
Retain the old of_machine_device_match() functionality using a cheap
static inline wrapper around the new of_machine_get_match() helper.

of: fix incorrect device creation for reserved memory nodes
The current global search for nodes in reserved_mem_matches can find nodes outside "/reserved-memory". These nodes might not have actual memory reserved (via memblock), leading to drivers (e.g., ramoops) accessing unreserved memory and causing memory corruption. Restrict the scan to the "/reserved-memory" node to ensure created devices are correctly backed by reserved memory. This enforces specification compliance and avoids dangerous probing.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

soc: driver updates for 7.0
There are are a number of to firmware drivers, in particular the TEE
subsystem:
- a bus callback for TEE firmware that device drivers can register to
- sysfs support for tee firmware information
- minor updates to platform specific TEE drivers for AMD, NXP, Qualcomm
and the generic optee driver
- ARM SCMI firmware refactoring to improve the protocol discover
among other fixes and cleanups
- ARM FF-A firmware interoperability improvements
The reset controller and memory controller subsystems gain support for
additional hardware platforms from Mediatek, Renesas, NXP, Canaan and
SpacemiT.
Most of the other changes are for random drivers/soc code. Among
a number of cleanups and newly added hardware support, including:
- Mediatek MT8196 DVFS power management and mailbox support
- Qualcomm SCM firmware and MDT loader refactoring, as part of
the new Glymur platform support.
- NXP i.MX9 System Manager firmware support for accessing the
syslog
- Minor updates for TI, Renesas, Samsung, Apple, Marvell and AMD
SoCs.

of: unittest: fix possible null-pointer dereferences in of_unittest_property_copy()
This function first duplicates p1 and p2 into new, and then checks whether
the duplication succeeds. However, if the duplication fails (e.g.,
kzalloc() returns NULL in __of_prop_dup()), new will be NULL but is still
dereferenced in __of_prop_free(). To ensure that the unit test continues to
run even when duplication fails, add a NULL check before calling
__of_prop_free().

of: fix reference count leak in of_alias_scan()
of_find_node_by_path() returns a device_node with its refcount
incremented. When kstrtoint() fails or dt_alloc() fails, the function
continues to the next iteration without calling of_node_put(), causing
a reference count leak.
Add of_node_put(np) before continue on both error paths to properly
release the device_node reference.

of: platform: Use default match table for /firmware
Calling of_platform_populate() without a match table will only populate
the immediate child nodes under /firmware. This is usually fine, but in
the case of something like a "simple-mfd" node such as
"raspberrypi,bcm2835-firmware", those child nodes will not be populated.
And subsequent calls won't work either because the /firmware node is
marked as processed already.
Switch the call to of_platform_default_populate() to solve this problem.
It should be a nop for existing cases.

of/irq: Introduce for_each_of_imap_item
for_each_of_imap_item is an iterator designed to help a driver to parse an interrupt-map property. Indeed some drivers need to know details about the interrupt mapping described in the device-tree in order to set internal registers accordingly.

of: unittest: Fix memory leak in unittest_data_add()
In unittest_data_add(), if of_resolve_phandles() fails, the allocated
unittest_data is not freed, leading to a memory leak.
Fix this by using scope-based cleanup helper __free(kfree) for automatic
resource cleanup. This ensures unittest_data is automatically freed when
it goes out of scope in error paths.
For the success path, use retain_and_null_ptr() to transfer ownership
of the memory to the device tree and prevent double freeing.

Updates for the interrupt core and treewide cleanups:
- Rework of the Per Processor Interrupt (PPI) management on ARM[64].
PPI support was built under the assumption that the systems are
homogenous so that the same CPU local device types are connected to
them. That's unfortunately wishful thinking and created horrible
workarounds.
This rework provides affinity management for PPIs so that they can be
individually configured in the firmware tables and mops up the related
drivers all over the place.
- Prevent CPUSET/isolation changes to arbitrarily affine interrupt
threads to random CPUs, which ignores user or driver settings.
- Plug a harmless race in the interrupt affinity proc interface, which
allows to see a half updated mask
- Adjust the priority of secondary interrupt threads on RT, so that the
combination of primary and secondary thread emulates the hardware
interrupt plus thread scenario. Having them at the same priority can
cause starvation issues in some drivers.

of: Add wrappers to match root node with OF device ID tables
Several drivers duplicate same code for getting reference to the root node, matching it against 'struct of_device_id' table and getting out the match data from the table entry. There is a of_machine_compatible_match() wrapper but it takes array of strings, which is not suitable for many drivers since they want the driver data associated with each compatible. Add two wrappers, similar to existing of_device_get_match_data(): 1. of_machine_device_match() doing only matching against 'struct of_device_id' and returning bool. 2. of_machine_get_match_data() doing the matching and returning associated driver data for found compatible.

of/irq: Handle explicit interrupt parent
If an interrupt controller is used as a proxy, it may have an
"interrupt-parent" property, but lack "interrupts" and
"interrupts-extended" properties. In that case, the "interrupt-parent"
property in the interrupt controller node is ignored, causing the
interrupt controller to fail to probe, and leading to system boot
failures or crashes.
Fix this by also considering an explicit "interrupt-parent" property in
the interrupt controller node itself.

of/irq: Ignore interrupt parent for nodes without interrupts
The Devicetree Specification states:
The root of the interrupt tree is determined when traversal of the
interrupt tree reaches an interrupt controller node without an
interrupts property and thus no explicit interrupt parent.
However, of_irq_init() gratuitously assumes that a node without
interrupts has an actual interrupt parent if it finds an
interrupt-parent property higher up in the device tree. Hence when such
a property is present (e.g. in the root node), the root interrupt
controller may not be detected as such, causing a panic:
OF: of_irq_init: children remain, but no parents
Kernel panic - not syncing: No interrupt controller found.

In of_msi_get_domain() if the iterator loop stops early because an irq_domain match is detected, an of_node_put() on the iterator node is needed to keep the OF node refcount in sync. Add it.

of/irq: Add msi-parent check to of_msi_xlate()
In some legacy platforms the MSI controller for a PCI host bridge is
identified by an msi-parent property whose phandle points at an MSI
controller node with no #msi-cells property, that implicitly
means #msi-cells == 0.
For such platforms, mapping a device ID and retrieving the MSI controller
node becomes simply a matter of checking whether in the device hierarchy
there is an msi-parent property pointing at an MSI controller node with
such characteristics.
Add a helper function to of_msi_xlate() to check the msi-parent property in
addition to msi-map and retrieve the MSI controller node (with a 1:1 ID
deviceID-IN<->deviceID-OUT mapping) to provide support for deviceID
mapping and MSI controller node retrieval for such platforms.

of: unittest: Fix device reference count leak in of_unittest_pci_node_verify
In of_unittest_pci_node_verify(), when the add parameter is false,
device_find_any_child() obtains a reference to a child device. This
function implicitly calls get_device() to increment the device's
reference count before returning the pointer. However, the caller
fails to properly release this reference by calling put_device(),
leading to a device reference count leak. Add put_device() in the else
branch immediately after child_dev is no longer needed.
As the comment of device_find_any_child states: "NOTE: you will need
to drop the reference with put_device() after use".
Found by code review.

With the introduction of the of_msi_xlate() function, the OF layer provides an API to map a device ID and retrieve the MSI controller node the ID is mapped to with a single call. of_msi_map_id() is currently used to map a deviceID to a specific MSI controller node; of_msi_xlate() can be used for that purpose too, there is no need to keep the two functions. Convert of_msi_map_id() to of_msi_xlate() calls and update the of_msi_xlate() documentation to describe how the struct device_node pointer passed in should be set-up to either provide the MSI controller node target or receive its pointer upon mapping completion.

of_numa: fix uninitialized memory nodes causing kernel panic
When there are memory-only nodes (nodes without CPUs), these nodes are not
properly initialized, causing kernel panic during boot.
of_numa_init
of_numa_parse_cpu_nodes
node_set(nid, numa_nodes_parsed);
of_numa_parse_memory_nodes
In of_numa_parse_cpu_nodes, numa_nodes_parsed gets updated only for nodes
containing CPUs. Memory-only nodes should have been updated in
of_numa_parse_memory_nodes, but they weren't.
Subsequently, when free_area_init() attempts to access NODE_DATA() for
these uninitialized memory nodes, the kernel panics due to NULL pointer
dereference.
This can be reproduced on ARM64 QEMU with 1 CPU and 2 memory nodes:
qemu-system-aarch64 \
-cpu host -nographic \
-m 4G -smp 1 \
-machine virt,accel=kvm,gic-version=3,iommu=smmuv3 \

If the of_changeset_add_property() function call fails, then this code
frees "new_pp" and then dereference it on the next line. Return the

of: dynamic: Fix memleak when of_pci_add_properties() failed
When of_pci_add_properties() failed, of_changeset_destroy() is called to
free the changeset. And of_changeset_destroy() puts device tree node in
each entry but does not free property in the entry. This leads to memory
leak in the failure case.
In of_changeset_add_prop_helper(), add the property to the device tree node
deadprops list. Thus, the property will also be freed along with device
tree node.

Restructure the call site for dma_contiguous_early_fixup() to
where the reserved_mem nodes are being parsed from the DT so that

ARM:
- Host driver for GICv5, the next generation interrupt controller for arm64, including support for interrupt routing, MSIs, interrupt translation and wired interrupts. - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on GICv5 hardware, leveraging the legacy VGIC interface. - Userspace control of the 'nASSGIcap' GICv3 feature, allowing userspace to disable support for SGIs w/o an active state on hardware that previously advertised it unconditionally. - Map supporting endpoints with cacheable memory attributes on systems with FEAT_S2FWB and DIC where KVM no longer needs to perform cache maintenance on the address range. - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest hypervisor to inject external aborts into an L2 VM and take traps of masked external aborts to the hypervisor. - Convert more system register sanitization to the config-driven implementation. - Fixes to the visibility of EL2 registers, namely making VGICv3 system registers accessible through the VGIC device instead of the ONE_REG vCPU ioctls. - Various cleanups and minor fixes. LoongArch: - Add stat information for in-kernel irqchip - Add tracepoints for CPUCFG and CSR emulation exits - Enhance in-kernel irqchip emulation - Various cleanups. RISC-V: - Enable ring-based dirty memory tracking - Improve perf kvm stat to report interrupt events - Delegate illegal instruction trap to VS-mode - MMU improvements related to upcoming nested virtualization s390x - Fixes x86: - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC, PIC, and PIT emulation at compile time. - Share device posted IRQ code between SVM and VMX and harden it against bugs and runtime errors. - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1) instead of O(n). - For MMIO stale data mitigation, track whether or not a vCPU has access to (host) MMIO based on whether the page tables have MMIO pfns mapped; using VFIO is prone to false negatives - Rework the MSR interception code so that the SVM and VMX APIs are more or less identical. - Recalculate all MSR intercepts from scratch on MSR filter changes, instead of maintaining shadow bitmaps. - Advertise support for LKGS (Load Kernel GS base), a new instruction that's loosely related to FRED, but is supported and enumerated independently. - Fix a user-triggerable WARN that syzkaller found by setting the vCPU in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU into VMX Root Mode (post-VMXON). Trying to detect every possible path leading to architecturally forbidden states is hard and even risks breaking userspace (if it goes from valid to valid state but passes through invalid states), so just wait until KVM_RUN to detect that the vCPU state isn't allowed. - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of APERF/MPERF reads, so that a "properly" configured VM can access APERF/MPERF. This has many caveats (APERF/MPERF cannot be zeroed on vCPU creation or saved/restored on suspend and resume, or preserved over thread migration let alone VM migration) but can be useful whenever you're interested in letting Linux guests see the effective physical CPU frequency in /proc/cpuinfo. - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been created, as there's no known use case for changing the default frequency for other VM types and it goes counter to the very reason why the ioctl was added to the vm file descriptor. And also, there would be no way to make it work for confidential VMs with a "secure" TSC, so kill two birds with one stone. - Dynamically allocation the shadow MMU's hashed page list, and defer allocating the hashed list until it's actually needed (the TDP MMU doesn't use the list). - Extract many of KVM's helpers for accessing architectural local APIC state to common x86 so that they can be shared by guest-side code for Secure AVIC. - Various cleanups and fixes. x86 (Intel): - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest. Failure to honor FREEZE_IN_SMM can leak host state into guests. - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to prevent L1 from running L2 with features that KVM doesn't support, e.g. BTF. x86 (AMD): - WARN and reject loading kvm-amd.ko instead of panicking the kernel if the nested SVM MSRPM offsets tracker can't handle an MSR (which is pretty much a static condition and therefore should never happen, but still). - Fix a variety of flaws and bugs in the AVIC device posted IRQ code. - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware supports) instead of rejecting vCPU creation. - Extend enable_ipiv module param support to SVM, by simply leaving IsRunning clear in the vCPU's physical ID table entry. - Disable IPI virtualization, via enable_ipiv, if the CPU is affected by erratum #1235, to allow (safely) enabling AVIC on such CPUs. - Request GA Log interrupts if and only if the target vCPU is blocking, i.e. only if KVM needs a notification in order to wake the vCPU. - Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to the vCPU's CPUID model. - Accept any SNP policy that is accepted by the firmware with respect to SMT and single-socket restrictions. An incompatible policy doesn't put the kernel at risk in any way, so there's no reason for KVM to care. - Drop a superfluous WBINVD (on all CPUs!) when destroying a VM and use WBNOINVD instead of WBINVD when possible for SEV cache maintenance. - When reclaiming memory from an SEV guest, only do cache flushes on CPUs that have ever run a vCPU for the guest, i.e. don't flush the caches for CPUs that can't possibly have cache lines with dirty, encrypted data. Generic: - Rework irqbypass to track/match producers and consumers via an xarray instead of a linked list. Using a linked list leads to O(n^2) insertion times, which is hugely problematic for use cases that create large numbers of VMs. Such use cases typically don't actually use irqbypass, but eliminating the pointless registration is a future problem to solve as it likely requires new uAPI. - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *", to avoid making a simple concept unnecessarily difficult to understand. - Decouple device posted IRQs from VFIO device assignment, as binding a VM to a VFIO group is not a requirement for enabling device posted IRQs. - Clean up and document/comment the irqfd assignment code. - Disallow binding multiple irqfds to an eventfd with a priority waiter, i.e. ensure an eventfd is bound to at most one irqfd through the entire host, and add a selftest to verify eventfd:irqfd bindings are globally unique. - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues related to private <=> shared memory conversions. - Drop guest_memfd's .getattr() implementation as the VFS layer will call generic_fillattr() if inode_operations.getattr is NULL. - Fix issues with dirty ring harvesting where KVM doesn't bound the processing of entries in any way, which allows userspace to keep KVM in a tight loop indefinitely. - Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking, now that KVM no longer uses assigned_device_count as a heuristic for either irqbypass usage or MDS mitigation. Selftests: - Fix a comment typo. - Verify KVM is loaded when getting any KVM module param so that attempting to run a selftest without kvm.ko loaded results in a SKIP message about KVM not being loaded/enabled (versus some random parameter not existing). - Skip tests that hit EACCES when attempting to access a file, and rpint a "Root required?" help message. In most cases, the test just needs to be run with elevated permissions. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmiKXMgUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroMhMQf/QDhC/CP1aGXph2whuyeD2NMqPKiU 9KdnDNST+ftPwjg9QxZ9mTaa8zeVz/wly6XlxD9OQHy+opM1wcys3k0GZAFFEEQm YrThgURdzEZ3nwJZgb+m0t4wjJQtpiFIBwAf7qq6z1VrqQBEmHXJ/8QxGuqO+BNC j5q/X+q6KZwehKI6lgFBrrOKWFaxqhnRAYfW6rGBxRXxzTJuna37fvDpodQnNceN zOiq+avfriUMArTXTqOteJNKU0229HjiPSnjILLnFQ+B3akBlwNG0jk7TMaAKR6q IZWG1EIS9q1BAkGXaw6DE1y6d/YwtXCR5qgAIkiGwaPt5yj9Oj6kRN2Ytw== =j2At -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "ARM: - Host driver for GICv5, the next generation interrupt controller for arm64, including support for interrupt routing, MSIs, interrupt translation and wired interrupts - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on GICv5 hardware, leveraging the legacy VGIC interface - Userspace control of the 'nASSGIcap' GICv3 feature, allowing userspace to disable support for SGIs w/o an active state on hardware that previously advertised it unconditionally - Map supporting endpoints with cacheable memory attributes on systems with FEAT_S2FWB and DIC where KVM no longer needs to perform cache maintenance on the address range - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest hypervisor to inject external aborts into an L2 VM and take traps of masked external aborts to the hypervisor - Convert more system register sanitization to the config-driven implementation - Fixes to the visibility of EL2 registers, namely making VGICv3 system registers accessible through the VGIC device instead of the ONE_REG vCPU ioctls - Various cleanups and minor fixes LoongArch: - Add stat information for in-kernel irqchip - Add tracepoints for CPUCFG and CSR emulation exits - Enhance in-kernel irqchip emulation - Various cleanups RISC-V: - Enable ring-based dirty memory tracking - Improve perf kvm stat to report interrupt events - Delegate illegal instruction trap to VS-mode - MMU improvements related to upcoming nested virtualization s390x - Fixes x86: - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC, PIC, and PIT emulation at compile time - Share device posted IRQ code between SVM and VMX and harden it against bugs and runtime errors - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1) instead of O(n) - For MMIO stale data mitigation, track whether or not a vCPU has access to (host) MMIO based on whether the page tables have MMIO pfns mapped; using VFIO is prone to false negatives - Rework the MSR interception code so that the SVM and VMX APIs are more or less identical - Recalculate all MSR intercepts from scratch on MSR filter changes, instead of maintaining shadow bitmaps - Advertise support for LKGS (Load Kernel GS base), a new instruction that's loosely related to FRED, but is supported and enumerated independently - Fix a user-triggerable WARN that syzkaller found by setting the vCPU in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU into VMX Root Mode (post-VMXON).

of/irq: Add of_msi_xlate() helper function
Add an of_msi_xlate() helper that maps a device ID and returns the device node of the MSI controller the device ID is mapped to. Required by core functions that need an MSI controller device node pointer at the same time as a mapped device ID, of_msi_map_id() is not sufficient for that purpose.

- The 11 patch series "Add folio_mk_pte()" from Matthew Wilcox
simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - The 8 patch series "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - The 3 patch series "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - The 2 patch series "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - The 8 patch series "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - The 6 patch series "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - The 3 patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - The 2 patch series "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - The 3 patch series "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - The 3 patch series "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - The 12 patch series "Always call constructor for kernel page tables" from Kevin Brodsky "ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables". This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - The 9 patch series "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - The 3 patch series "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - The 4 patch series "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - The 6 patch series "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - The 3 patch series "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - The 3 patch series ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support". Fixes things on error paths which we are unlikely to hit. - The 7 patch series "mm/damon: auto-tune DAMOS for NUMA setups including tiered memory" from SeongJae Park introduces new DAMOS quota goal metrics which eliminate the manual tuning which is required when utilizing DAMON for memory tiering. - The 5 patch series "mm/vmalloc.c: code cleanup and improvements" from Baoquan He provides cleanups and small efficiency improvements which Baoquan found via code inspection. - The 2 patch series "vmscan: enforce mems_effective during demotion" from Gregory Price "changes reclaim to respect cpuset.mems_effective during demotion when possible". because "presently, reclaim explicitly ignores cpuset.mems_effective when demoting, which may cause the cpuset settings to violated." "This is useful for isolating workloads on a multi-tenant system from certain classes of memory more consistently." - The 2 patch series ""Clean up split_huge_pmd_locked() and remove unnecessary folio pointers" from Gavin Guo provides minor cleanups and efficiency gains in in the huge page splitting and migrating code. - The 3 patch series "Use kmem_cache for memcg alloc" from Huan Yang creates a slab cache for `struct mem_cgroup', yielding improved memory utilization. - The 4 patch series "add max arg to swappiness in memory.reclaim and lru_gen" from Zhongkun He adds a new "max" argument to the "swappiness=" argument for memory.reclaim MGLRU's lru_gen. This directs proactive reclaim to reclaim from only anon folios rather than file-backed folios. - The 17 patch series "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the first step on the path to permitting the kernel to maintain existing VMs while replacing the host kernel via file-based kexec. At this time only memblock's reserve_mem is preserved. - The 7 patch series "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides and uses a smarter way of looping over a pfn range. By skipping ranges of invalid pfns. - The 2 patch series "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning when a task is pinned a single NUMA mode.

of: reserved_mem: Add functions to parse "memory-region"
Drivers with "memory-region" properties currently have to do their own parsing of "memory-region" properties. The result is all the drivers have similar patterns of a call to parse "memory-region" and then get the region's address and size. As this is a standard property, it should have common functions for drivers to use. Add new functions to count the number of regions and retrieve the region's address as a resource.

Networking changes for 6.15.
Core & protocols
----------------
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls).
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked)
in BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream performance
up to 2x.
- Improve performance of contended connect() by 200% by searching
for an available 4-tuple under RCU rather than a spin lock.
Bring an additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles.
There are up to 4 namespace roles but we used to have just 2 netns
pointer arguments, interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout
in TCP.
- Support masking port and DSCP in routing rule matches.
- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.
- Support specifying at what time packet should be sent on AF_XDP
sockets.
- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users.
- Add Netlink YAML spec for WiFi (nl80211) and conntrack.
- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a module.
- Age FDB entries based on Rx not Tx traffic in VxLAN, similar
to normal bridging.
- Allow users to specify source port range for GENEVE tunnels.
- netconsole: allow attaching kernel release, CPU ID and task name
to messages as metadata
Driver API
----------
- Continue rework / fixing of Energy Efficient Ethernet (EEE) across
the SW layers. Delegate the responsibilities to phylink where possible.
Improve its handling in phylib.
