mm/hugetlb: fix races when looking up a CONT-PTE/PMD size hugetlb page
On some architectures (like ARM64), it can support CONT-PTE/PMD size hugetlb, which means it can support not only PMD/PUD size hugetlb (2M and 1G), but also CONT-PTE/PMD size(64K and 32M) if a 4K page size specified. So when looking up a CONT-PTE size hugetlb page by follow_page(), it will use pte_offset_map_lock() to get the pte entry lock for the CONT-PTE size hugetlb in follow_page_pte(). However this pte entry lock is incorrect for the CONT-PTE size hugetlb, since we should use huge_pte_lock() to get the correct lock, which is mm->page_table_lock. That means the pte entry of the CONT-PTE size hugetlb under current pte lock is unstable in follow_page_pte(), we can continue to migrate or poison the pte entry of the CONT-PTE size hugetlb, which can cause some potential race issues, even though they are under the 'pte lock'. For example, suppose thread A is trying to look up a CONT-PTE size hugetlb page by move_pages() syscall under the lock, however antoher thread B can migrate the CONT-PTE hugetlb page at the same time, which will cause thread A to get an incorrect page, if thread A also wants to do page migration, then data inconsistency error occurs. Moreover we have the same issue for CONT-PMD size hugetlb in follow_huge_pmd(). To fix above issues, rename the follow_huge_pmd() as follow_huge_pmd_pte() to handle PMD and PTE level size hugetlb, which uses huge_pte_lock() to get the correct pte entry lock to make the pte entry stable. Mike said: Support for CONT_PMD/_PTE was added with |

treewide: use get_random_u32() when possible
The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

Merge tag 'pci-v6.1-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull pci updates from Bjorn Helgaas:
"Resource management:
- Distribute spare resources to unconfigured hotplug bridges at
boot-time (not just when hot-adding such a bridge), which makes
hot-adding devices to docks work better.
- Revert to a BAR assignment inherited from firmware only when the
address is actually reachable via any upstream bridges, which fixes
some cases where firmware doesn't configure all devices.
- Add a sysfs interface to resize BARs so this can be done before
assigning devices to a VM through VFIO.
Power management:
- Disable Precision Time Management for all devices on suspend to
enable lower-power PM state. We previously did this just for Root
Ports, which isn't enough because downstream devices can still
generate PTM messages, which cause errors if it's disabled in the
Root Port.
- Save and restore the ASPM L1 PM Substates configuration for
suspend/ resume. Previously this configuration was lost, so L1.x
states likely stopped working after resume.
- Check whether the L1 PM Substates Capability exists. If it didn't
exist, we previously read junk and tried to configure L1 Substates
based on that.
- Fix the LTR_L1.2_THRESHOLD computation, which previously set a
threshold for entering L1.2 that was too low in some cases.
- Reduce the delay after transitions to or from D3cold by using
usleep_range() rather than msleep(), which often slept for ~19ms
instead of the 10ms normally required. The spec says 10ms is
enough, but it's possible we could trip over devices that need a
little more.
Error handling:
- Work around a BIOS bug that caused Intel Root Ports to advertise a
Root Port Programmed I/O (RP PIO) log size of zero, which caused
annoying warnings and prevented the kernel from dumping log
registers for DPC errors.
Qualcomm PCIe controller driver:
- Add support for SC8280XP and SA8540P host controllers and SM8450
endpoint controller.
- Disable Master AXI clock on endpoint controllers to save power when
link is idle or in L1.x.
- Expose link state transition counts via debugfs to help debug
issues with low-power states.
- Add auto-loading module support.
Synopsys DesignWare PCIe controller driver:
- Remove a dependency on ZONE_DMA32 by allocating the MSI target page
differently. There's more work to do related to eDMA controllers,
so it's not completely settled"

Pull f2fs updates from Jaegeuk Kim:
"This round looks fairly small comparing to the previous updates and
includes mostly minor bug fixes. Nevertheless, as we've still
interested in improving the stability, Chao added some debugging
methods to diagnoze subtle runtime inconsistency problem.
Enhancements:
- store all the corruption or failure reasons in superblock
- detect meta inode, summary info, and block address inconsistency
- increase the limit for reserve_root for low-end devices
- add the number of compressed IO in iostat
Bug fixes:
- DIO write fix for zoned devices
- do out-of-place writes for cold files

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 Howlett. An overlapping range-based tree for vmas. It it apparently slightly 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 at [1]. 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.

- Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES (Phil Auld)
- cleanup nr_cpu_ids vs nr_cpumask_bits mess (me)
This series cleans that mess and adds new config FORCE_NR_CPUS that
allows to optimize cpumask subsystem if the number of CPUs is known
at compile-time.
- optimize find_bit() functions (me)
Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT()
macros.
- add find_nth_bit() (me)
Adds find_nth_bit(), which is ~70 times faster than bitcounting with
for_each() loop:
for_each_set_bit(bit, mask, size)
if (n-- == 0)
return bit;
Also adds bitmap_weight_and() to let people replace this pattern:
tmp = bitmap_alloc(nbits);
bitmap_and(tmp, map1, map2, nbits);
weight = bitmap_weight(tmp, nbits);
bitmap_free(tmp);
with a single bitmap_weight_and() call.
- repair cpumask_check() (me)
After switching cpumask to use nr_cpu_ids, cpumask_check() started
generating many false-positive warnings. This series fixes it.
- Add for_each_cpu_andnot() and for_each_cpu_andnot() (Valentin
Schneider)

- 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. This 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
- Other minor clean ups and fixes"

Merge tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld: - Huawei reported that when they updated their kernel from 4.4 to something much newer, some userspace code they had broke, the culprit being the accidental removal of O_NONBLOCK from /dev/random way back in 5.6. It's been gone for over 2 years now and this is the first we've heard of it, but userspace breakage is userspace breakage, so O_NONBLOCK is now back. - Use randomness from hardware RNGs much more often during early boot, at the same interval that crng reseeds are done, from Dominik. - A semantic change in hardware RNG throttling, so that the hwrng framework can properly feed random.c with randomness from hardware RNGs that aren't specifically marked as creditable. A related patch coming to you via Herbert's hwrng tree depends on this one, not to compile, but just to function properly, so you may want to merge this PULL before that one. - A fix to clamp credited bits from the interrupts pool to the size of the pool sample. This is mainly just a theoretical fix, as it'd be pretty hard to exceed it in practice. - Oracle reported that InfiniBand TCP latency regressed by around 10-15% after a change a few cycles ago made at the request of the RT folks, in which we hoisted a somewhat rare operation (1 in 1024 times) out of the hard IRQ handler and into a workqueue, a pretty common and boring pattern. It turns out, though, that scheduling a worker from there has overhead of its own, whereas scheduling a timer on that same CPU for the next jiffy amortizes better and doesn't incur the same overhead. I also eliminated a cache miss by moving the work_struct (and subsequently, the timer_list) to below a critical cache line, so that the more critical members that are accessed on every hard IRQ aren't split between two cache lines. - The boot-time initialization of the RNG has been split into two approximate phases: what we can accomplish before timekeeping is possible and what we can accomplish after. This winds up being useful so that we can use RDRAND to seed the RNG before CONFIG_SLAB_FREELIST_RANDOM=y systems initialize slabs, in addition to other early uses of randomness. The effect is that systems with RDRAND (or a bootloader seed) will never see any warnings at all when setting CONFIG_WARN_ALL_UNSEEDED_RANDOM=y. And kfence benefits from getting a better seed of its own. - Small systems without much entropy sometimes wind up putting some truncated serial number read from flash into hostname, so contribute utsname changes to the RNG, without crediting. - Add smaller batches to serve requests for smaller integers, and make use of them when people ask for random numbers bounded by a given compile-time constant. This has positive effects all over the tree, most notably in networking and kfence. - The original jitter algorithm intended (I believe) to schedule the timer for the next jiffy, not the next-next jiffy, yet it used mod_timer(jiffies + 1), which will fire on the next-next jiffy, instead of what I believe was intended, mod_timer(jiffies), which will fire on the next jiffy. So fix that. - Fix a comment typo, from William. * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: clear new batches when bringing new CPUs online random: fix typos in get_random_bytes() comment random: schedule jitter credit for next jiffy, not in two jiffies prandom: make use of smaller types in prandom_u32_max random: add 8-bit and 16-bit batches utsname: contribute changes to RNG random: use init_utsname() instead of utsname() kfence: use better stack hash seed random: split initialization into early step and later step random: use expired timer rather than wq for mixing fast pool random: avoid reading two cache lines on irq randomness random: clamp credited irq bits to maximum mixed random: throttle hwrng writes if no entropy is credited random: use hwgenerator randomness more frequently at early boot random: restore O_NONBLOCK support |

Merge tag 'slab-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab fixes from Vlastimil Babka:
- The "common kmalloc v4" series [1] by Hyeonggon Yoo.
While the plan after LPC is to try again if it's possible to get rid
of SLOB and SLAB (and if any critical aspect of those is not possible
to achieve with SLUB today, modify it accordingly), it will take a
while even in case there are no objections.
Meanwhile this is a nice cleanup and some parts (e.g. to the
tracepoints) will be useful even if we end up with a single slab
implementation in the future:
- Improves the mm/slab_common.c wrappers to allow deleting
duplicated code between SLAB and SLUB.
- Large kmalloc() allocations in SLAB are passed to page allocator
like in SLUB, reducing number of kmalloc caches.
- Removes the {kmem_cache_alloc,kmalloc}_node variants of
tracepoints, node id parameter added to non-_node variants.
- Addition of kmalloc_size_roundup()
The first two patches from a series by Kees Cook [2] that introduce
kmalloc_size_roundup(). This will allow merging of per-subsystem
patches using the new function and ultimately stop (ab)using ksize()
in a way that causes ongoing trouble for debugging functionality and
static checkers.
- Wasted kmalloc() memory tracking in debugfs alloc_traces
A patch from Feng Tang that enhances the existing debugfs
alloc_traces file for kmalloc caches with information about how much
space is wasted by allocations that needs less space than the
particular kmalloc cache provides.
- My series [3] to fix validation races for caches with enabled
debugging:
- By decoupling the debug cache operation more from non-debug
fastpaths, extra locking simplifications were possible and thus
done afterwards.
- Additional cleanup of PREEMPT_RT specific code on top, by Thomas
Gleixner.
- A late fix for slab page leaks caused by the series, by Feng
Tang.
- Smaller fixes and cleanups:
- Unneeded variable removals, by ye xingchen
- A cleanup removing a BUG_ON() in create_unique_id(), by Chao Yu

On PREEMPT_RT enabled kernels, spinlocks and rwlocks are neither disabling preemption nor interrupts. Though there are a few places which depend on the implicit preemption/interrupt disable of those locks, e.g. seqcount write sections, per CPU statistics updates etc. PREEMPT_RT added open coded CONFIG_PREEMPT_RT conditionals to disable/enable preemption in the related code parts all over the place. That's hard to read and does not really explain why this is necessary. Linus suggested to use helper functions (preempt_disable_nested() and preempt_enable_nested()) and use those in the affected places.

block: avoid sign extend problem with default queue flags mask
request_queue->queue_flags is unsigned long, which is 8-bytes on 64-bit architectures. Most queue flag modifications occur through bit field helpers, but default flags can be logically OR'd via the QUEUE_FLAG_MQ_DEFAULT mask. If this mask happens to include bit 31, the assignment can sign extend the field and set all upper 32 bits. This exact problem has been observed on a downstream kernel that happens to use bit 31 for QUEUE_FLAG_NOWAIT. This is not an immediate problem for current upstream because bit 31 is not included in the default flag assignment (and is not used at all, actually). Regardless, fix up the QUEUE_FLAG_MQ_DEFAULT mask definition to avoid the landmine in the future.

At the time it was realized that part of the problem was that while the ucount rlimits were very similar to the oridinary ucounts (in being nested counts with limits) the semantics were slightly different and the code would be less error prone if there was less sharing. This is the long awaited cleanup that should hopefully keep things more comprehensible and less error prone for whoever needs to touch that code next" * tag 'ucount-rlimits-cleanups-for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: ucounts: Split rlimit and ucount values and max values |

Pull ptrace update from Eric Biederman: "ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT Recently I had a conversation where it was pointed out to me that SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite difficult for a tracer to handle. Keeping SIGKILL working after the process has been killed is pain from an implementation point of view. So since the debuggers don't want this behavior let's see if we can remove this wart for the userspace API If a regression is detected it should only need to be the last change that is the reverted. The other two are just general cleanups that make the last patch simpler" * tag 'signal-for-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal: Drop signals received after a fatal signal has been processed signal: Guarantee that SIGNAL_GROUP_EXIT is set on process exit signal: Ensure SIGNAL_GROUP_EXIT gets set in do_group_exit |

Pull kvm updates from Paolo Bonzini:
"The first batch of KVM patches, mostly covering x86.
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

Merge tag 'efi-next-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
"A bit more going on than usual in the EFI subsystem. The main driver
for this has been the introduction of the LoonArch architecture last
cycle, which inspired some cleanup and refactoring of the EFI code.
Another driver for EFI changes this cycle and in the future is
confidential compute.
The LoongArch architecture does not use either struct bootparams or DT
natively [yet], and so passing information between the EFI stub and
the core kernel using either of those is undesirable. And in general,
overloading DT has been a source of issues on arm64, so using DT for
this on new architectures is a to avoid for the time being (even if we
might converge on something DT based for non-x86 architectures in the
future). For this reason, in addition to the patch that enables EFI
boot for LoongArch, there are a number of refactoring patches applied
on top of which separate the DT bits from the generic EFI stub bits.
These changes are on a separate topich branch that has been shared
with the LoongArch maintainers, who will include it in their pull
request as well. This is not ideal, but the best way to manage the
conflicts without stalling LoongArch for another cycle.
Another development inspired by LoongArch is the newly added support
for EFI based decompressors. Instead of adding yet another
arch-specific incarnation of this pattern for LoongArch, we are
introducing an EFI app based on the existing EFI libstub
infrastructure that encapulates the decompression code we use on other
architectures, but in a way that is fully generic. This has been
developed and tested in collaboration with distro and systemd folks,
who are eager to start using this for systemd-boot and also for arm64
secure boot on Fedora. Note that the EFI zimage files this introduces
can also be decompressed by non-EFI bootloaders if needed, as the
image header describes the location of the payload inside the image,
and the type of compression that was used. (Note that Fedora's arm64
GRUB is buggy [0] so you'll need a recent version or switch to
systemd-boot in order to use this.)
Finally, we are adding TPM measurement of the kernel command line
provided by EFI. There is an oversight in the TCG spec which results
in a blind spot for command line arguments passed to loaded images,
which means that either the loader or the stub needs to take the
measurement. Given the combinatorial explosion I am anticipating when
it comes to firmware/bootloader stacks and firmware based attestation
protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now
when it comes to EFI measured boot, which is that the kernel measures
the initrd and command line. Intermediate loaders can measure
additional assets if needed, but with the baseline in place, we can
deploy measured boot in a meaningful way even if you boot into Linux
straight from the EFI firmware.
Summary:
- implement EFI boot support for LoongArch
- implement generic EFI compressed boot support for arm64, RISC-V and
LoongArch, none of which implement a decompressor today
- measure the kernel command line into the TPM if measured boot is in
effect
- refactor the EFI stub code in order to isolate DT dependencies for
architectures other than x86
- avoid calling SetVirtualAddressMap() on arm64 if the configured
size of the VA space guarantees that doing so is unnecessary
- move some ARM specific code out of the generic EFI source files
- unmap kernel code from the x86 mixed mode 1:1 page tables"
