Add more test cases for LPM trie in test_maps:
1) test_lpm_trie_update_flags
It constructs various use cases for BPF_EXIST and BPF_NOEXIST and check
whether the return value of update operation is expected.
2) test_lpm_trie_update_full_maps
It tests the update operations on a full LPM trie map. Adding new node
will fail and overwriting the value of existed node will succeed.
3) test_lpm_trie_iterate_strs and test_lpm_trie_iterate_ints
There two test cases test whether the iteration through get_next_key is
sorted and expected. These two test cases delete the minimal key after
each iteration and check whether next iteration returns the second
minimal key. The only difference between these two test cases is the
former one saves strings in the LPM trie and the latter saves integers.
Without the fix of get_next_key, these two cases will fail as shown
below:
test_lpm_trie_iterate_strs(1091):FAIL:iterate #2 got abc exp abS
test_lpm_trie_iterate_ints(1142):FAIL:iterate #1 got 0x2 exp 0x1

Move test_lpm_map.c to map_tests/ to include LPM trie test cases in
regular test_maps run. Most code remains unchanged, including the use of
assert(). Only reduce n_lookups from 64K to 512, which decreases
test_lpm_map runtime from 37s to 0.7s.

Add a __caps_unpriv annotation so that tests requiring specific
capabilities while dropping the rest can conveniently specify them
during selftest declaration instead of munging with capabilities at
runtime from the testing binary.
While at it, let us convert test_verifier_mtu to use this new support
instead.
Since we do not want to include linux/capability.h, we only defined the
four main capabilities BPF subsystem deals with in bpf_misc.h for use in
tests. If the user passes a CAP_SYS_NICE or anything else that's not
defined in the header, capability parsing code will return a warning.
Also reject strtol returning 0. CAP_CHOWN = 0 but we'll never need to
use it, and strtol doesn't errno on failed conversion. Fail the test in
such a case.
The original diff for this idea is available at link [0].

Andrii spotted that process_dynptr_func's rejection of incorrect
argument register type will print an error string where argument numbers
are not zero-indexed, unlike elsewhere in the verifier. Fix this by
subtracting 1 from regno. The same scenario exists for iterator
messages. Fix selftest error strings that match on the exact argument
number while we're at it to ensure clean bisection.

Currently, KF_ARG_PTR_TO_ITER handling missed checking the reg->type and
ensuring it is PTR_TO_STACK. Instead of enforcing this in the caller of
process_iter_arg, move the check into it instead so that all callers
will gain the check by default. This is similar to process_dynptr_func.
An existing selftest in verifier_bits_iter.c fails due to this change,
but it's because it was passing a NULL pointer into iter_next helper and
getting an error further down the checks, but probably meant to pass an
uninitialized iterator on the stack (as is done in the subsequent test
below it). We will gain coverage for non-PTR_TO_STACK arguments in later
patches hence just change the declaration to zero-ed stack object.

bpftool now embeds the kfuncs definitions directly in the generated

This is great, but because the selftests dir might be compiled with

If we have the kfuncs, because we have the `__not_used` hack, the newly

Prevent vmlinux.h to define its kfuncs and also add the missing `__weak`

Pull modules updates from Luis Chamberlain:
- The whole caching of module code into huge pages by Mike Rapoport is
going in through Andrew Morton's tree due to some other code
dependencies. That's really the biggest highlight for Linux kernel
modules in this release. With it we share huge pages for modules,
starting off with x86. Expect to see that soon through Andrew!
- Helge Deller addressed some lingering low hanging fruit alignment
enhancements by. It is worth pointing out that from his old patch
series I dropped his vmlinux.lds.h change at Masahiro's request as he
would prefer this to be specified in asm code [0].

- Matthew Maurer and Sami Tolvanen have been tag teaming to help get us
closer to a modversions for Rust. In this cycle we take in quite a
lot of the refactoring for ELF validation. I expect modversions for
Rust will be merged by v6.14 as that code is mostly ready now.
- Adds a new modules selftests: kallsyms which helps us tests
find_symbol() and the limits of kallsyms on Linux today.
- We have a realtime mailing list to kernel-ci testing for modules now
which relies and combines patchwork, kpd and kdevops:
https://patchwork.kernel.org/project/linux-modules/list/
https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/README.md

https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/linux-modules-kdevops-ci.md
If you want to help avoid Linux kernel modules regressions, now its
simple, just add a new Linux modules sefltests under
tools/testing/selftests/module/ That is it. All new selftests will be
used and leveraged automatically by the CI.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
callers can't stop a device multiple times, even as we migrate from
the global pci_rescan_remove_lock to finer-grained locking (Keith
Busch)
- Improve pci_walk_bus() implementation by making it recursive and
moving locking up to avoid need for a 'locked' parameter (Keith
Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by
the PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence
'trustworthy' by a heuristic since the 'ExternalFacingPort' and
'usb4-host-interface' ACPI properties are not quite enough (Esther
Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties
when building dynamic DT nodes so systems where PCI and CPU
addresses differ work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce
redundancy (Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish
the conversion from returning 'int' to being 'void' (Sergio
Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request
all BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and
release a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when
there was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay
Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
as required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate()
to create pwrctl platform devices so we can control it based on the
child nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power
supply property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a
race where pwrctl could change device power state while the PCI
driver was active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node()
instead of searching all children of the parent (Manivannan
Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into
pcie_lbms_seen(), where it can be shared between the bandwidth
controller and quirks that use it to help retrain failed links
(Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address
the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers
can manage PCIe Link speed based on thermal or other constraints
(Ilpo Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the
existing thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function
device where function 0 has a management console interface to
enable/disable and provision various personalities for the other
functions (Shijith Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and
doesn't handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and
PCI_ACS_CR were set, so the functions can be in independent IOMMU
groups (Mengyuan Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a
request to the mailbox to avoid failures if the mailbox is still
busy from a previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if
the requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
handle controller-specific size and alignment constraints, and add
test cases to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
observe DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks
'mmio' DT property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when
removing the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware
erratum that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of
clocks for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire
Root Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a
previous commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP
v5.80a and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the
qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
can be used by other Qcom platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the
link comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
to support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation
(Qiang Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
.align value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead
of searching for it, and verify that the address was mapped (Damien
Le Moal)

been mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to
rockchip_pcie_ep_get_resources() for consistency with similar DT
interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
it only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it
(Damien Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated
resets and start link training after PERST# is deasserted (Damien
Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match
an ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
us), before deasserting PERST# to ensure power and refclk are
stable (Siddharth Vadapalli)

test_sockmap
Add this to more comprehensively test the socket memory accounting logic
in the __SK_REDIRECT and __SK_DROP cases of tcp_bpf_sendmsg. We don't have
test when apply_bytes are not zero in test_txmsg_redir_wait_sndmem.
test_send_large has opt->rate=2, it will invoke sendmsg two times.
Specifically, the first sendmsg will trigger the case where the ret value
of tcp_bpf_sendmsg_redir is less than 0; while the second sendmsg happens
after the 3 seconds timeout, and it will trigger __SK_DROP because socket
c2 has been removed from the sockmap/hash.

CONFIG_PREEMPT is a preemtion model the so called "Low-Latency Desktop".
A different preemption model is PREEMPT_RT the so called "Real-Time".
Both implement preemption in kernel and set CONFIG_PREEMPTION.
There is also the so called "LAZY PREEMPT" which the "Scheduler
controlled preemption model". Here we have also preemption in the kernel
the rules are slightly different.
Therefore the testsuite should not check for CONFIG_PREEMPT (as one
model) but for CONFIG_PREEMPTION to figure out if preemption in the
kernel is possible.

This reverts commit 6fd47effe92b, and the related self-test update
commit e14e0eaeb040 ("selftests/hid: add test for assigning a given
device to hid-generic").
It results in things like the scroll wheel on Logitech mice not working
after a reboot due to the kernel being confused about the state of the
high-resolution mode.
Quoting Benjamin Tissoires:
"The idea of 6fd47effe92b was to be able to call hid_bpf_rdesc_fixup()
once per reprobe of the device.
However, because the bpf filter can now change the quirk value, the
call had to be moved before the driver gets bound (which was
previously ensuring the unicity of the call).
The net effect is that now, in the case hid-generic gets loaded first
and then the specific driver gets loaded once the disk is available,
the value of ->quirks is not reset, but kept to the value that was set
by hid-generic (HID_QUIRK_INPUT_PER_APP).
Once hid-logitech-hidpp kicks in, that quirk is now set, which creates
two inputs for the single mouse: one keyboard for fancy shortcuts, and
one mouse node.
However, hid-logitech-hidpp expects only one input node to be attached
(it stores it into hidpp->input), and when a wheel event is received,
because there is some processing with high-resolution wheel events,
the wheel event is injected into hidpp->input.
And of course, when HID_QUIRK_INPUT_PER_APP is set, hidpp->input gets
the keyboard node, which doesn't have wheel event type, and the events
are ignored"

Pull kvm updates from Paolo Bonzini:
"The biggest change here is eliminating the awful idea that KVM had of
essentially guessing which pfns are refcounted pages.
The reason to do so was that KVM needs to map both non-refcounted
pages (for example BARs of VFIO devices) and VM_PFNMAP/VM_MIXMEDMAP
VMAs that contain refcounted pages.
However, the result was security issues in the past, and more recently
the inability to map VM_IO and VM_PFNMAP memory that _is_ backed by
struct page but is not refcounted. In particular this broke virtio-gpu
blob resources (which directly map host graphics buffers into the
guest as "vram" for the virtio-gpu device) with the amdgpu driver,
because amdgpu allocates non-compound higher order pages and the tail
pages could not be mapped into KVM.
This requires adjusting all uses of struct page in the
per-architecture code, to always work on the pfn whenever possible.
The large series that did this, from David Stevens and Sean
Christopherson, also cleaned up substantially the set of functions
that provided arch code with the pfn for a host virtual addresses.
The previous maze of twisty little passages, all different, is
replaced by five functions (__gfn_to_page, __kvm_faultin_pfn, the
non-__ versions of these two, and kvm_prefetch_pages) saving almost
200 lines of code.
ARM:
- Support for stage-1 permission indirection (FEAT_S1PIE) and
permission overlays (FEAT_S1POE), including nested virt + the
emulated page table walker
- Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This
call was introduced in PSCIv1.3 as a mechanism to request
hibernation, similar to the S4 state in ACPI
- Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As
part of it, introduce trivial initialization of the host's MPAM
context so KVM can use the corresponding traps
- PMU support under nested virtualization, honoring the guest
hypervisor's trap configuration and event filtering when running a
nested guest
- Fixes to vgic ITS serialization where stale device/interrupt table
entries are not zeroed when the mapping is invalidated by the VM
- Avoid emulated MMIO completion if userspace has requested
synchronous external abort injection
- Various fixes and cleanups affecting pKVM, vCPU initialization, and
selftests
LoongArch:
- Add iocsr and mmio bus simulation in kernel.
- Add in-kernel interrupt controller emulation.
- Add support for virtualization extensions to the eiointc irqchip.
PPC:
- Drop lingering and utterly obsolete references to PPC970 KVM, which
was removed 10 years ago.
- Fix incorrect documentation references to non-existing ioctls
RISC-V:
- Accelerate KVM RISC-V when running as a guest
- Perf support to collect KVM guest statistics from host side
s390:
- New selftests: more ucontrol selftests and CPU model sanity checks
- Support for the gen17 CPU model
- List registers supported by KVM_GET/SET_ONE_REG in the
documentation
x86:
- Cleanup KVM's handling of Accessed and Dirty bits to dedup code,
improve documentation, harden against unexpected changes.
Even if the hardware A/D tracking is disabled, it is possible to
use the hardware-defined A/D bits to track if a PFN is Accessed
and/or Dirty, and that removes a lot of special cases.
- Elide TLB flushes when aging secondary PTEs, as has been done in
x86's primary MMU for over 10 years.
- Recover huge pages in-place in the TDP MMU when dirty page logging
is toggled off, instead of zapping them and waiting until the page
is re-accessed to create a huge mapping. This reduces vCPU jitter.
- Batch TLB flushes when dirty page logging is toggled off. This
reduces the time it takes to disable dirty logging by ~3x.
- Remove the shrinker that was (poorly) attempting to reclaim shadow
page tables in low-memory situations.
- Clean up and optimize KVM's handling of writes to
MSR_IA32_APICBASE.
- Advertise CPUIDs for new instructions in Clearwater Forest
- Quirk KVM's misguided behavior of initialized certain feature MSRs
to their maximum supported feature set, which can result in KVM
creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to
a non-zero value results in the vCPU having invalid state if
userspace hides PDCM from the guest, which in turn can lead to
save/restore failures.
- Fix KVM's handling of non-canonical checks for vCPUs that support
LA57 to better follow the "architecture", in quotes because the
actual behavior is poorly documented. E.g. most MSR writes and
descriptor table loads ignore CR4.LA57 and operate purely on
whether the CPU supports LA57.
- Bypass the register cache when querying CPL from kvm_sched_out(),
as filling the cache from IRQ context is generally unsafe; harden
the cache accessors to try to prevent similar issues from occuring
in the future. The issue that triggered this change was already
fixed in 6.12, but was still kinda latent.
- Advertise AMD_IBPB_RET to userspace, and fix a related bug where
KVM over-advertises SPEC_CTRL when trying to support cross-vendor
VMs.
- Minor cleanups
- Switch hugepage recovery thread to use vhost_task.
These kthreads can consume significant amounts of CPU time on
behalf of a VM or in response to how the VM behaves (for example
how it accesses its memory); therefore KVM tried to place the
thread in the VM's cgroups and charge the CPU time consumed by that
work to the VM's container.
However the kthreads did not process SIGSTOP/SIGCONT, and therefore
cgroups which had KVM instances inside could not complete freezing.
Fix this by replacing the kthread with a PF_USER_WORKER thread, via
the vhost_task abstraction. Another 100+ lines removed, with
generally better behavior too like having these threads properly
parented in the process tree.
- Revert a workaround for an old CPU erratum (Nehalem/Westmere) that
didn't really work; there was really nothing to work around anyway:
the broken patch was meant to fix nested virtualization, but the
PERF_GLOBAL_CTRL MSR is virtualized and therefore unaffected by the
erratum.
- Fix 6.12 regression where CONFIG_KVM will be built as a module even
if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is
'y'.
x86 selftests:
- x86 selftests can now use AVX.
Documentation:
- Use rST internal links
- Reorganize the introduction to the API document
Generic:
- Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock
instead of RCU, so that running a vCPU on a different task doesn't
encounter long due to having to wait for all CPUs become quiescent.
In general both reads and writes are rare, but userspace that
supports confidential computing is introducing the use of "helper"
vCPUs that may jump from one host processor to another. Those will
be very happy to trigger a synchronize_rcu(), and the effect on
performance is quite the disaster"

git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd updates from Jason Gunthorpe:
"Several new features and uAPI for iommufd:
- IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the
backing memory for an iommu mapping. To date VFIO/iommufd have used
VMA's and pin_user_pages(), this now allows using memfds and
memfd_pin_folios(). Notably this creates a pure folio path from the
memfd to the iommu page table where memory is never broken down to
PAGE_SIZE.
- IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between
two processes. Combined with the above this allows iommufd to
support a VMM re-start using exec() where something like qemu would
exec() a new version of itself and fd pass the memfds/iommufd/etc
to the new process. The memfd allows DMA access to the memory to
continue while the new process is getting setup, and the
CHANGE_PROCESS updates all the accounting.
- Support for fault reporting to userspace on non-PRI HW, such as ARM
stall-mode embedded devices.
- IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed
virtual iommu. This will be used by VMMs to access hardware
features that are contained with in a VM. The first use is to
inform the kernel of the virtual SID to physical SID mapping when
issuing SID based invalidation on ARM. Further uses will tie HW
features that are directly accessed by the VM, such as invalidation
queue assignment and others.
- IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual
device to physical device within a VIOMMU. Minimially this is used
to translate VM issued cache invalidation commands from virtual to
physical device IDs.
- Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work
with the VIOMMU
- ARM SMMuv3 support for nested translation. Using the VIOMMU and
VDEVICE the driver can model this HW's behavior for nested
translation. This includes a shared branch from Will"

Pull networking updates from Paolo Abeni:
"The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core:
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of
rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code:
- Add small file operations for debugfs, to reduce the struct ops
size.
- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.
Netfilter:
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.
BPF:
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols:
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after
close, the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state
lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per
device neigh lists.
Driver API:
- Introduce a unified interface to configure transmission H/W
shaping, and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling:
- forwarding: introduce deferred commands, to simplify the cleanup
phase
Drivers:
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ftrace updates from Steven Rostedt:
- Restructure the function graph shadow stack to prepare it for use
with kretprobes
With the goal of merging the shadow stack logic of function graph and
kretprobes, some more restructuring of the function shadow stack is
required.
Move out function graph specific fields from the fgraph
infrastructure and store it on the new stack variables that can pass
data from the entry callback to the exit callback.
Hopefully, with this change, the merge of kretprobes to use fgraph
shadow stacks will be ready by the next merge window.
- Make shadow stack 4k instead of using PAGE_SIZE.
Some architectures have very large PAGE_SIZE values which make its
use for shadow stacks waste a lot of memory.
- Give shadow stacks its own kmem cache.
When function graph is started, every task on the system gets a
shadow stack. In the future, shadow stacks may not be 4K in size.
Have it have its own kmem cache so that whatever size it becomes will
still be efficient in allocations.
- Initialize profiler graph ops as it will be needed for new updates to
fgraph
- Convert to use guard(mutex) for several ftrace and fgraph functions
- Add more comments and documentation
- Show function return address in function graph tracer
Add an option to show the caller of a function at each entry of the
function graph tracer, similar to what the function tracer does.
- Abstract out ftrace_regs from being used directly like pt_regs
ftrace_regs was created to store a partial pt_regs. It holds only the
registers and stack information to get to the function arguments and
return values. On several archs, it is simply a wrapper around
pt_regs. But some users would access ftrace_regs directly to get the
pt_regs which will not work on all archs. Make ftrace_regs an
abstract structure that requires all access to its fields be through
accessor functions.
- Show how long it takes to do function code modifications
When code modification for function hooks happen, it always had the
time recorded in how long it took to do the conversion. But this
value was never exported. Recently the code was touched due to new
ROX modification handling that caused a large slow down in doing the
modifications and had a significant impact on boot times.
Expose the timings in the dyn_ftrace_total_info file. This file was
created a while ago to show information about memory usage and such
to implement dynamic function tracing. It's also an appropriate file
to store the timings of this modification as well. This will make it
easier to see the impact of changes to code modification on boot up
timings.
