selftests/vm: use memfd for hugetlb-madvise test
For dropping the hugetlb mountpoint in run_vmtests.sh. Since no parameter is needed, drop USAGE too.

selftests/vm: use memfd for uffd hugetlb tests
Patch series "selftests/vm: Drop hugetlb mntpoint in run_vmtests.sh", v2. Clean the code up so we can use the same memfd for both hugetlb and shmem which is cleaner. This patch (of 4): We already used memfd for shmem test, move it forward with hugetlb too so that we don't need user to specify the hugetlb file path explicitly when running hugetlb shared tests.

ksefltests: pidfd: Fix wait_states: Test terminated by timeout
0Day/LKP observed that the kselftest blocks forever since one of the pidfd_wait doesn't terminate in 1 of 30 runs. After digging into the source, we found that it blocks at: ASSERT_EQ(sys_waitid(P_PIDFD, pidfd, &info, WCONTINUED, NULL), 0); wait_states has below testing flow: CHILD PARENT ---------------+-------------- 1 STOP itself 2 WAIT for CHILD STOPPED 3 SIGNAL CHILD to CONT 4 CONT 5 STOP itself 5' WAIT for CHILD CONT 6 WAIT for CHILD STOPPED The problem is that the kernel cannot ensure the order of 5 and 5', once 5 goes first, the test will fail. we can reproduce it by: $ while true; do make run_tests -C pidfd; done Introduce a blocking read in child process to make sure the parent can check its WCONTINUED.

KVM: selftests: Mark "guest_saw_irq" as volatile in xen_shinfo_test
Tag "guest_saw_irq" as "volatile" to ensure that the compiler will never
optimize away lookups. Relying on the compiler thinking that the flag
is global and thus might change also works, but it's subtle, less robust,
and looks like a bug at first glance, e.g. risks being "fixed" and
breaking the test.
Make the flag "static" as well since convincing the compiler it's global
is no longer necessary.
Alternatively, the flag could be accessed with {READ,WRITE}_ONCE(), but
literally every access would need the wrappers, and eking out performance
isn't exactly top priority for selftests.

KVM: selftests: Add tests in xen_shinfo_test to detect lock races
Tests for races between shinfo_cache (de)activation and hypercall+ioctl() processing. KVM has had bugs where activating the shared info cache multiple times and/or with concurrent users results in lock corruption, NULL pointer dereferences, and other fun. For the timer injection testcase (#22), re-arm the timer until the IRQ is successfully injected. If the timer expires while the shared info is deactivated (invalid), KVM will drop the event.

selftests: add openvswitch selftest suite
Previous commit resolves a WARN splat that can be difficult to reproduce, but with the ovs-dpctl.py utility, it can be trivial. Introduce a test case which creates a DP, and then downgrades the feature set. This will include a utility 'ovs-dpctl.py' that can be extended to do additional tests and diagnostics.

KVM: selftests: Fix number of pages for memory slot in memslot_modification_stress_test
It's required by vm_userspace_mem_region_add() that memory size
should be aligned to host page size. However, one guest page is
provided by memslot_modification_stress_test. It triggers failure
in the scenario of 64KB-page-size-host and 4KB-page-size-guest,
as the following messages indicate.
# ./memslot_modification_stress_test

mm/selftest: uffd: explain the write missing fault check
It's not obvious why we had a write check for each of the missing messages, especially when it should be a locking op. Add a rich comment for that, and also try to explain its good side and limitations, so that if someone hit it again for either a bug or a different glibc impl there'll be some clue to start with.

- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam R. Howlett. An overlapping range-based tree for vmas. It it apparently slight more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com). This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths.

Tracing updates for 6.1:
Major changes:
- Changed location of tracing repo from personal git repo to:
git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git
- Added Masami Hiramatsu as co-maintainer
- Updated MAINTAINERS file to separate out FTRACE as it is
more than just TRACING.
Minor changes:
- Added Mark Rutland as FTRACE reviewer
- Updated user_events to make it on its way to remove the BROKEN tag.
The changes should now be acceptable but will run it through
a cycle and hopefully we can remove the BROKEN tag next release.
- Added filtering to eprobes
- Added a delta time to the benchmark trace event
- Have the histogram and filter callbacks called via a switch
statement instead of indirect functions. This speeds it up to
avoid retpolines.
- Add a way to wake up ring buffer waiters waiting for the
ring buffer to fill up to its watermark.
- New ioctl() on the trace_pipe_raw file to wake up ring buffer
waiters.
- Wake up waiters when the ring buffer is disabled.
A reader may block when the ring buffer is disabled,
but if it was blocked when the ring buffer is disabled
it should then wake up.
Fixes:
- Allow splice to read partially read ring buffer pages
Fixes splice never moving forward.
- Fix inverted compare that made the "shortest" ring buffer
wait queue actually the longest.
- Fix a race in the ring buffer between resetting a page when
a writer goes to another page, and the reader.
- Fix ftrace accounting bug when function hooks are added at
boot up before the weak functions are set to "disabled".
- Fix bug that freed a user allocated snapshot buffer when
enabling a tracer.
- Fix possible recursive locks in osnoise tracer
- Fix recursive locking direct functions
- And other minor clean ups and fixes

cgroup changes for v6.1-rc1.
* cpuset now support isolated cpus.partition type, which will enable dynamic
CPU isolation.
* pids.peak added to remember the max number of pids used.
* Holes in cgroup namespace plugged.
* Internal cleanups.
Note that for-6.1-fixes was pulled into for-6.1 twice. Both were for
follow-up cleanups and each merge commit has details.

Locking changes for v6.1:
- Disable preemption in rwsem_write_trylock()'s attempt to
take the rwsem, to avoid RT tasks hogging the CPU, which
managed to preempt this function after the owner has
been cleared but before a new owner is set. Also add
debug checks to enforce this.
- Add __lockfunc to more slow path functions and add
__sched to semaphore functions.
- Mark spinlock APIs noinline when the respective CONFIG_INLINE_SPIN_*
toggles are disabled, to reduce LTO text size.
- Print more debug information when lockdep gets confused
in look_up_lock_class().
- Improve header file abuse checks.
- Misc cleanups

The first batch of KVM patches, mostly covering x86, which I
am sending out early due to me travelling next week. There is a lone mm patch for which Andrew gave an informal ack at https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org. I will send the bulk of ARM work, as well as other architectures, at the end of next week. ARM: * Account stage2 page table allocations in memory stats. x86: * Account EPT/NPT arm64 page table allocations in memory stats. * Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses. * Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of Hyper-V now support eVMCS fields associated with features that are enumerated to the guest. * Use KVM's sanitized VMCS config as the basis for the values of nested VMX capabilities MSRs. * A myriad event/exception fixes and cleanups. Most notably, pending exceptions morph into VM-Exits earlier, as soon as the exception is queued, instead of waiting until the next vmentry. This fixed a longstanding issue where the exceptions would incorrecly become double-faults instead of triggering a vmexit; the common case of page-fault vmexits had a special workaround, but now it's fixed for good. * A handful of fixes for memory leaks in error paths. * Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow. * Never write to memory from non-sleepable kvm_vcpu_check_block() * Selftests refinements and cleanups. * Misc typo cleanups. Generic: * remove KVM_REQ_UNHALT -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmM2zwcUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroNpbwf+MlVeOlzE5SBdrJ0TEnLmKUel1lSz QnZzP5+D65oD0zhCilUZHcg6G4mzZ5SdVVOvrGJvA0eXh25ruLNMF6jbaABkMLk/ FfI1ybN7A82hwJn/aXMI/sUurWv4Jteaad20JC2DytBCnsW8jUqc49gtXHS2QWy4 3uMsFdpdTAg4zdJKgEUfXBmQviweVpjjl3ziRyZZ7yaeo1oP7XZ8LaE1nR2l5m0J mfjzneNm5QAnueypOh5KhSwIvqf6WHIVm/rIHDJ1HIFbgfOU0dT27nhb1tmPwAcE +cJnnMUHjZqtCXteHkAxMClyRq0zsEoKk0OGvSOOMoq3Q0DavSXUNANOig== =/hqX -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "The first batch of KVM patches, mostly covering x86.
