Pull modules updates from Luis Chamberlain: "The only thing worth highligthing is that gzip moves to use vmalloc() instead of kmalloc just as we had a fix for this for zstd on v6.6-rc1. The rest is regular house keeping, keeping things neat, tidy, and boring" [ The kmalloc -> vmalloc conversion is not the right approach. Unless you know you need huge areas or know you need to use virtual mappings for some reason (playing with protection bits or whatever), you should use kvmalloc()/kvfree, which automatically picks the right allocation model - Linus ] * tag 'modules-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module: Annotate struct module_notes_attrs with __counted_by module: Fix comment typo module: Make is_valid_name() return bool module: Make is_mapping_symbol() return bool module/decompress: use vmalloc() for gzip decompression workspace MAINTAINERS: add include/linux/module*.h to modules module: Clarify documentation of module_param_call()

Pull sysctl updates from Luis Chamberlain: "To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array. Joel Granados has been doing all this work. On the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove the sentinel. Both arch and driver changes have been on linux-next for a bit less than a month. It is worth re-iterating the value: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files For v6.8-rc1 expect removal of all the sentinels and also then the unneeded check for procname == NULL. The last two patches are fixes recently merged by Krister Johansen which allow us again to use softlockup_panic early on boot. This used to work but the alias work broke it. This is useful for folks who want to detect softlockups super early rather than wait and spend money on cloud solutions with nothing but an eventual hung kernel. Although this hadn't gone through linux-next it's also a stable fix, so we might as well roll through the fixes now" * tag 'sysctl-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: (23 commits) watchdog: move softlockup_panic back to early_param proc: sysctl: prevent aliased sysctls from getting passed to init intel drm: Remove now superfluous sentinel element from ctl_table array Drivers: hv: Remove now superfluous sentinel element from ctl_table array raid: Remove now superfluous sentinel element from ctl_table array fw loader: Remove the now superfluous sentinel element from ctl_table array sgi-xp: Remove the now superfluous sentinel element from ctl_table array vrf: Remove the now superfluous sentinel element from ctl_table array char-misc: Remove the now superfluous sentinel element from ctl_table array infiniband: Remove the now superfluous sentinel element from ctl_table array macintosh: Remove the now superfluous sentinel element from ctl_table array parport: Remove the now superfluous sentinel element from ctl_table array scsi: Remove now superfluous sentinel element from ctl_table array tty: Remove now superfluous sentinel element from ctl_table array xen: Remove now superfluous sentinel element from ctl_table array hpet: Remove now superfluous sentinel element from ctl_table array c-sky: Remove now superfluous sentinel element from ctl_talbe array powerpc: Remove now superfluous sentinel element from ctl_table arrays riscv: Remove now superfluous sentinel element from ctl_table array x86/vdso: Remove now superfluous sentinel element from ctl_table array ...

Pull iommufd updates from Jason Gunthorpe: "This brings three new iommufd capabilities: - Dirty tracking for DMA. AMD/ARM/Intel CPUs can now record if a DMA writes to a page in the IOPTEs within the IO page table. This can be used to generate a record of what memory is being dirtied by DMA activities during a VM migration process. A VMM like qemu will combine the IOMMU dirty bits with the CPU's dirty log to determine what memory to transfer. VFIO already has a DMA dirty tracking framework that requires PCI devices to implement tracking HW internally. The iommufd version provides an alternative that the VMM can select, if available. The two are designed to have very similar APIs. - Userspace controlled attributes for hardware page tables (HWPT/iommu_domain). There are currently a few generic attributes for HWPTs (support dirty tracking, and parent of a nest). This is an entry point for the userspace iommu driver to control the HW in detail. - Nested translation support for HWPTs. This is a 2D translation scheme similar to the CPU where a DMA goes through a first stage to determine an intermediate address which is then translated trough a second stage to a physical address. Like for CPU translation the first stage table would exist in VM controlled memory and the second stage is in the kernel and matches the VM's guest to physical map. As every IOMMU has a unique set of parameter to describe the S1 IO page table and its associated parameters the userspace IOMMU driver has to marshal the information into the correct format. This is 1/3 of the feature, it allows creating the nested translation and binding it to VFIO devices, however the API to support IOTLB and ATC invalidation of the stage 1 io page table, and forwarding of IO faults are still in progress. The series includes AMD and Intel support for dirty tracking. Intel support for nested translation. Along the way are a number of internal items: - New iommu core items: ops->domain_alloc_user(), ops->set_dirty_tracking, ops->read_and_clear_dirty(), IOMMU_DOMAIN_NESTED, and iommu_copy_struct_from_user - UAF fix in iopt_area_split() - Spelling fixes and some test suite improvement" * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: (52 commits) iommufd: Organize the mock domain alloc functions closer to Joerg's tree iommufd/selftest: Fix page-size check in iommufd_test_dirty() iommufd: Add iopt_area_alloc() iommufd: Fix missing update of domains_itree after splitting iopt_area iommu/vt-d: Disallow read-only mappings to nest parent domain iommu/vt-d: Add nested domain allocation iommu/vt-d: Set the nested domain to a device iommu/vt-d: Make domain attach helpers to be extern iommu/vt-d: Add helper to setup pasid nested translation iommu/vt-d: Add helper for nested domain allocation iommu/vt-d: Extend dmar_domain to support nested domain iommufd: Add data structure for Intel VT-d stage-1 domain allocation iommu/vt-d: Enhance capability check for nested parent domain allocation iommufd/selftest: Add coverage for IOMMU_HWPT_ALLOC with nested HWPTs iommufd/selftest: Add nested domain allocation for mock domain iommu: Add iommu_copy_struct_from_user helper iommufd: Add a nested HW pagetable object iommu: Pass in parent domain with user_data to domain_alloc_user op iommufd: Share iommufd_hwpt_alloc with IOMMUFD_OBJ_HWPT_NESTED iommufd: Derive iommufd_hwpt_paging from iommufd_hw_pagetable ...

Pull probes updates from Masami Hiramatsu: "Cleanups: - kprobes: Fixes typo in kprobes samples - tracing/eprobes: Remove 'break' after return kretprobe/fprobe performance improvements: - lib: Introduce new `objpool`, which is a high performance lockless object queue. This uses per-cpu ring array to allocate/release objects from the pre-allocated object pool. Since the index of ring array is a 32bit sequential counter, we can retry to push/pop the object pointer from the ring without lock (as seq-lock does) - lib: Add an objpool test module to test the functionality and evaluate the performance under some circumstances - kprobes/fprobe: Improve kretprobe and rethook scalability performance with objpool. This improves both legacy kretprobe and fprobe exit handler (which is based on rethook) to be scalable on SMP systems. Even with 8-threads parallel test, it shows a great scalability improvement - Remove unneeded freelist.h which is replaced by objpool - objpool: Add maintainers entry for the objpool - objpool: Fix to remove unused include header lines" * tag 'probes-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: kprobes: unused header files removed MAINTAINERS: objpool added kprobes: freelist.h removed kprobes: kretprobe scalability improvement lib: objpool test module added lib: objpool added: ring-array based lockless MPMC tracing/eprobe: drop unneeded breaks samples: kprobes: Fixes a typo

Pull io_uring futex support from Jens Axboe: "This adds support for using futexes through io_uring - first futex wake and wait, and then the vectored variant of waiting, futex waitv. For both wait/wake/waitv, we support the bitset variant, as the 'normal' variants can be easily implemented on top of that. PI and requeue are not supported through io_uring, just the above mentioned parts. This may change in the future, but in the spirit of keeping this small (and based on what people have been asking for), this is what we currently have. Wake support is pretty straight forward, most of the thought has gone into the wait side to avoid needing to offload wait operations to a blocking context. Instead, we rely on the usual callbacks to retry and post a completion event, when appropriate. As far as I can recall, the first request for futex support with io_uring came from Andres Freund, working on postgres. His aio rework of postgres was one of the early adopters of io_uring, and futex support was a natural extension for that. This is relevant from both a usability point of view, as well as for effiency and performance. In Andres's words, for the former: Futex wait support in io_uring makes it a lot easier to avoid deadlocks in concurrent programs that have their own buffer pool: Obviously pages in the application buffer pool have to be locked during IO. If the initiator of IO A needs to wait for a held lock B, the holder of lock B might wait for the IO A to complete. The ability to wait for a lock and IO completions at the same time provides an efficient way to avoid such deadlocks and in terms of effiency, even without unlocking the full potential yet, Andres says: Futex wake support in io_uring is useful because it allows for more efficient directed wakeups. For some "locks" postgres has queues implemented in userspace, with wakeup logic that cannot easily be implemented with FUTEX_WAKE_BITSET on a single "futex word" (imagine waiting for journal flushes to have completed up to a certain point). Thus a "lock release" sometimes need to wake up many processes in a row. A quick-and-dirty conversion to doing these wakeups via io_uring lead to a 3% throughput increase, with 12% fewer context switches, albeit in a fairly extreme workload" * tag 'io_uring-futex-2023-10-30' of git://git.kernel.dk/linux: io_uring: add support for vectored futex waits futex: make the vectored futex operations available futex: make futex_parse_waitv() available as a helper futex: add wake_data to struct futex_q io_uring: add support for futex wake and wait futex: abstract out a __futex_wake_mark() helper futex: factor out the futex wake handling futex: move FUTEX2_VALID_MASK to futex.h

Use a similar approach as commit a419beac ("module/decompress: use vmalloc() for zstd decompression workspace") and replace kmalloc() with vmalloc() also for the gzip module decompression workspace. In this case the workspace is represented by struct inflate_workspace that can be fairly large for kmalloc() and it can potentially lead to allocation errors on certain systems: $ pahole inflate_workspace struct inflate_workspace { struct inflate_state inflate_state; /* 0 9544 */ /* --- cacheline 149 boundary (9536 bytes) was 8 bytes ago --- */ unsigned char working_window[32768]; /* 9544 32768 */ /* size: 42312, cachelines: 662, members: 2 */ /* last cacheline: 8 bytes */ }; Considering that there is no need to use continuous physical memory, simply switch to vmalloc() to provide a more reliable in-kernel module decompression.

Commit 9bbb9e5a ("param: use ops in struct kernel_param, rather than get and set fns directly") added the comment that module_param_call() was deprecated, during a large scale refactoring to bring sanity to type casting back then. In 2017 following more cleanups, it became useful again as it wraps a common pattern of creating an ops struct for a given get/set pair: b2f270e8 ("module: Prepare to convert all module_param_call() prototypes") ece1996a ("module: Do not paper over type mismatches in module_param_call()") static const struct kernel_param_ops __param_ops_##name = \ { .flags = 0, .set = _set, .get = _get }; \ __module_param_call(MODULE_PARAM_PREFIX, \ name, &__param_ops_##name, arg, perm, -1, 0) __module_param_call(MODULE_PARAM_PREFIX, name, ops, arg, perm, -1, 0) Many users of module_param_cb() appear to be almost universally open-coding the same thing that module_param_call() does now. Don't discourage[1] people from using module_param_call(): clarify the comment to show that module_param_cb() is useful if you repeatedly use the same pair of get/set functions.

Setting softlockup_panic from do_sysctl_args() causes it to take effect later in boot. The lockup detector is enabled before SMP is brought online, but do_sysctl_args runs afterwards. If a user wants to set softlockup_panic on boot and have it trigger should a softlockup occur during onlining of the non-boot processors, they could do this prior to commit f117955a ("kernel/watchdog.c: convert {soft/hard}lockup boot parameters to sysctl aliases"). However, after this commit the value of softlockup_panic is set too late to be of help for this type of problem. Restore the prior behavior.

The code that checks for unknown boot options is unaware of the sysctl alias facility, which maps bootparams to sysctl values. If a user sets an old value that has a valid alias, a message about an invalid parameter will be printed during boot, and the parameter will get passed to init. Fix by checking for the existence of aliased parameters in the unknown boot parameter code. If an alias exists, don't return an error or pass the value to init.
