Certain platforms host a number of higher OPPs that are exclusive to CPUs within specific CPUfreq policies and not all CPUs within that CPUfreq policy are able to achieve those higher OPPs due to power constraints. These OPPs are marked as turbo in the freq_table and in the presence of such OPPs, let's enable boost by default.

Commit 0499a783 ("ARM64: Dynamically allocate cpumasks and increase supported CPUs to 512") changed the handling of cpumasks on ARM 64bit, what resulted in the strange issues and warnings during cpufreq-dt initialization on some big.LITTLE platforms. This was caused by mixing OPPs between big and LITTLE cores, because OPP-sharing information between big and LITTLE cores is computed on cpumask, which in turn was not zeroed on allocation. Fix this by switching to zalloc_cpumask_var() call.

In the existing code, per-policy flags don't have any impact i.e. if cpufreq_driver boost is enabled and boost is disabled for one or more of the policies, the cpufreq driver will behave as if boost is enabled. Fix this by incorporating per-policy boost flag in the policy->max computation used in cpufreq_frequency_table_cpuinfo and setting the default per-policy boost to mirror the cpufreq_driver boost flag.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Pull gpio updates from Bartosz Golaszewski: "The biggest feature is the locking overhaul. Up until now the synchronization in the GPIO subsystem was broken. There was a single spinlock "protecting" multiple data structures but doing it wrong (as evidenced by several places where it would be released when a sleeping function was called and then reacquired without checking the protected state). We tried to use an RW semaphore before but the main issue with GPIO is that we have drivers implementing the interfaces in both sleeping and non-sleeping ways as well as user-facing interfaces that can be called both from process as well as atomic contexts. Both ends converge in the same code paths that can use neither spinlocks nor mutexes. The only reasonable way out is to use SRCU and go mostly lockless. To that end: we add several SRCU structs in relevant places and use them to assure consistency between API calls together with atomic reads and writes of GPIO descriptor flags where it makes sense. This code has spent several weeks in next and has received several fixes in the first week or two after which it stabilized nicely. The GPIO subsystem is now resilient to providers being suddenly unbound. We managed to also remove the existing character device RW semaphore and the obsolete global spinlock. Other than the locking rework we have one new driver (for Chromebook EC), much appreciated documentation improvements from Kent and the regular driver improvements, DT-bindings updates and GPIOLIB core tweaks. Serialization rework: - use SRCU to serialize access to the global GPIO device list, to GPIO device structs themselves and to GPIO descriptors - make the GPIO subsystem resilient to the GPIO providers being unbound while the API calls are in progress - don't dereference the SRCU-protected chip pointer if the information we need can be obtained from the GPIO device structure - move some of the information contained in struct gpio_chip to struct gpio_device to further reduce the need to dereference the former - pass the GPIO device struct instead of the GPIO chip to sysfs callback to, again, reduce the need for accessing the latter - get GPIO descriptors from the GPIO device, not from the chip for the same reason - allow for mostly lockless operation of the GPIO driver API: assure consistency with SRCU and atomic operations - remove the global GPIO spinlock - remove the character device RW semaphore Core GPIOLIB: - constify pointers in GPIO API where applicable - unify the GPIO counting APIs for ACPI and OF - provide a macro for iterating over all GPIOs, not only the ones that are requested - remove leftover typedefs - pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for improved logging - constify the GPIO bus type - don't warn about removing GPIO chips with descriptors still held by users as we can now handle this situation gracefully - remove unused logging helpers - unexport functions that are only used internally in the GPIO subsystem - set the device type (assign the relevant struct device_type) for GPIO devices New drivers: - add the ChromeOS EC GPIO driver Driver improvements: - allow building gpio-vf610 with COMPILE_TEST as well as disabling it in menuconfig (before it was always built for i.MX cofigs) - count the number of EICs using the device properties instead of hard-coding it in gpio-eic-sprd - improve the device naming, extend the debugfs output and add lockdep asserts to gpio-sim DT bindings: - document the 'label' property for gpio-pca9570 - convert aspeed,ast2400-gpio bindings to DT schema - disallow unevaluated properties for gpio-mvebu - document a new model in renesas,rcar-gpio Documentation: - improve the character device kerneldocs in user-space headers - add proper documentation for the character device uAPI (both v1 and v2) - move the sysfs and gpio-mockup docs into the "obsolete" section - improve naming consistency for GPIO terms - clarify the line values description for sysfs - minor docs improvements - improve the driver API contract for setting GPIO direction - mark unsafe APIs as deprecated in kerneldocs and suggest replacements Other: - remove an obsolete test from selftests" * tag 'gpio-updates-for-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (79 commits) gpio: sysfs: repair export returning -EPERM on 1st attempt selftest: gpio: remove obsolete gpio-mockup test gpiolib: Deduplicate cleanup for-loop in gpiochip_add_data_with_key() dt-bindings: gpio: aspeed,ast2400-gpio: Convert to DT schema gpio: acpi: Make acpi_gpio_count() take firmware node as a parameter gpio: of: Make of_gpio_get_count() take firmware node as a parameter gpiolib: Pass consumer device through to core in devm_fwnode_gpiod_get_index() gpio: sim: use for_each_hwgpio() gpio: provide for_each_hwgpio() gpio: don't warn about removing GPIO chips with active users anymore gpio: sim: delimit the fwnode name with a ":" when generating labels gpio: sim: add lockdep asserts gpio: Add ChromeOS EC GPIO driver gpio: constify of_phandle_args in of_find_gpio_device_by_xlate() gpio: fix memory leak in gpiod_request_commit() gpio: constify opaque pointer "data" in gpio_device_find() gpio: cdev: fix a NULL-pointer dereference with DEBUG enabled gpio: uapi: clarify default_values being logical gpio: sysfs: fix inverted pointer logic gpio: don't let lockdep complain about inherently dangerous RCU usage ...

Pull device mapper VDO target from Mike Snitzer: "Introduce the DM vdo target which provides block-level deduplication, compression, and thin provisioning. Please see: Documentation/admin-guide/device-mapper/vdo.rst Documentation/admin-guide/device-mapper/vdo-design.rst The DM vdo target handles its concurrency by pinning an IO, and subsequent stages of handling that IO, to a particular VDO thread. This aspect of VDO is "unique" but its overall implementation is very tightly coupled to its mostly lockless threading model. As such, VDO is not easily changed to use more traditional finer-grained locking and Linux workqueues. Please see the "Zones and Threading" section of vdo-design.rst The DM vdo target has been used in production for many years but has seen significant changes over the past ~6 years to prepare it for upstream inclusion.

Pull ata updates from Niklas Cassel: - Do not enable LPM for external ports (hotplug-capable ports or eSATA ports), as the HBA will not be able to detect hot plug removal events when LPM is enabled (me) - Drop the board type board_ahci_low_power. Now when we make sure that we won't enable LPM for external ports, we can always set the LPM policy to CONFIG_SATA_MOBILE_LPM_POLICY for internal ports. There is thus no longer any need for the board type board_ahci_low_power, so it can be removed. (As before, LPM features not supported by the HBA and/or the device will not be enabled, regardless of the LPM policy Kconfig) (Mario Limonciello) Note that the default CONFIG_SATA_MOBILE_LPM_POLICY value is still 0 (which will not try to enable any LPM features), however, most Linux distributions override this and set it to 3 (Medium power with DIPM). We intend to change the default to 3 in the coming cycles, but we will wait a cycle or two. - Add board type board_ahci_pcs_quirk and make all legacy Intel platforms use it. The Intel PCS quirk was being applied to basically all Intel platforms, which caused some issues (the device failing to come back after a reset), when being applied to newer Intel platforms where it shouldn't have been applied. New platforms can be added using board type board_ahci, which will not have the quirk applied (me) - Rename board_ahci_nosntf to board_ahci_pcs_quirk_no_sntf to more clearly highlight that it applies two different quirks (me) - Modify the ahci_broken_devslp() quirk to be implemented like all the other quirks (i.e. define a board type for the quirk) (me) - Drop unused board_ahci_noncq board type (me) - Rename board_ahci_nomsi to board_ahci_no_msi to match the other board types (me) - Make pata_parport_bus_type const (Ricardo B.

Yes, yes, I know the slab people were planning on going slow and letting every subsystem fight this thing on their own. But let's just rip off the band-aid and get it over and done with. I don't want to see a number of unnecessary pull requests just to get rid of a flag that no longer has any meaning. This was mainly done with a couple of 'sed' scripts and then some manual cleanup of the end result.

Pull slab updates from Vlastimil Babka: - Freelist loading optimization (Chengming Zhou) When the per-cpu slab is depleted and a new one loaded from the cpu partial list, optimize the loading to avoid an irq enable/disable cycle. This results in a 3.5% performance improvement on the "perf bench sched messaging" test. - Kernel boot parameters cleanup after SLAB removal (Xiongwei Song) Due to two different main slab implementations we've had boot parameters prefixed either slab_ and slub_ with some later becoming an alias as both implementations gained the same functionality (i.e. slab_nomerge vs slub_nomerge). In order to eventually get rid of the implementation-specific names, the canonical and documented parameters are now all prefixed slab_ and the slub_ variants become deprecated but still working aliases. - SLAB_ kmem_cache creation flags cleanup (Vlastimil Babka) The flags had hardcoded #define values which became tedious and error-prone when adding new ones. Assign the values via an enum that takes care of providing unique bit numbers. Also deprecate SLAB_MEM_SPREAD which was only used by SLAB, so it's a no-op since SLAB removal. Assign it an explicit zero value. The removals of the flag usage are handled independently in the respective subsystems, with a final removal of any leftover usage planned for the next release. - Misc cleanups and fixes (Chengming Zhou, Xiaolei Wang, Zheng Yejian) Includes removal of unused code or function parameters and a fix of a memleak. * tag 'slab-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: slab: remove PARTIAL_NODE slab_state mm, slab: remove memcg_from_slab_obj() mm, slab: remove the corner case of inc_slabs_node() mm/slab: Fix a kmemleak in kmem_cache_destroy() mm, slab, kasan: replace kasan_never_merge() with SLAB_NO_MERGE mm, slab: use an enum to define SLAB_ cache creation flags mm, slab: deprecate SLAB_MEM_SPREAD flag mm, slab: fix the comment of cpu partial list mm, slab: remove unused object_size parameter in kmem_cache_flags() mm/slub: remove parameter 'flags' in create_kmalloc_caches() mm/slub: remove unused parameter in next_freelist_entry() mm/slub: remove full list manipulation for non-debug slab mm/slub: directly load freelist from cpu partial slab in the likely case mm/slub: make the description of slab_min_objects helpful in doc mm/slub: replace slub_$params with slab_$params in slub.rst mm/slub: unify all sl[au]b parameters with "slab_$param" Documentation: kernel-parameters: remove noaliencache

Pull lsm updates from Paul Moore: - Promote IMA/EVM to a proper LSM This is the bulk of the diffstat, and the source of all the changes in the VFS code. Prior to the start of the LSM stacking work it was important that IMA/EVM were separate from the rest of the LSMs, complete with their own hooks, infrastructure, etc. as it was the only way to enable IMA/EVM at the same time as a LSM. However, now that the bulk of the LSM infrastructure supports multiple simultaneous LSMs, we can simplify things greatly by bringing IMA/EVM into the LSM infrastructure as proper LSMs. This is something I've wanted to see happen for quite some time and Roberto was kind enough to put in the work to make it happen. - Use the LSM hook default values to simplify the call_int_hook() macro Previously the call_int_hook() macro required callers to supply a default return value, despite a default value being specified when the LSM hook was defined. This simplifies the macro by using the defined default return value which makes life easier for callers and should also reduce the number of return value bugs in the future (we've had a few pop up recently, hence this work). - Use the KMEM_CACHE() macro instead of kmem_cache_create() The guidance appears to be to use the KMEM_CACHE() macro when possible and there is no reason why we can't use the macro, so let's use it. - Fix a number of comment typos in the LSM hook comment blocks Not much to say here, we fixed some questionable grammar decisions in the LSM hook comment blocks. * tag 'lsm-pr-20240312' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (28 commits) cred: Use KMEM_CACHE() instead of kmem_cache_create() lsm: use default hook return value in call_int_hook() lsm: fix typos in security/security.c comment headers integrity: Remove LSM ima: Make it independent from 'integrity' LSM evm: Make it independent from 'integrity' LSM evm: Move to LSM infrastructure ima: Move IMA-Appraisal to LSM infrastructure ima: Move to LSM infrastructure integrity: Move integrity_kernel_module_request() to IMA security: Introduce key_post_create_or_update hook security: Introduce inode_post_remove_acl hook security: Introduce inode_post_set_acl hook security: Introduce inode_post_create_tmpfile hook security: Introduce path_post_mknod hook security: Introduce file_release hook security: Introduce file_post_open hook security: Introduce inode_post_removexattr hook security: Introduce inode_post_setattr hook security: Align inode_setattr hook definition with EVM ...

We've only got a couple of files left to cleanup and once we're done with that we can start enabling some automatic style verfication and introduce tooling to help new folks format their code correctly. - Don't restrict xattr copy-up when SELinux policy is not loaded This helps systems that use overlayfs, or similar filesystems, preserve their SELinux labels during early boot when the SELinux policy has yet to be loaded. - Reduce the work we do during inode initialization time This isn't likely to show up in any benchmark results, but we removed an unnecessary SELinux object class lookup/calculation during inode initialization. - Correct the return values in selinux_socket_getpeersec_dgram() We had some inconsistencies with respect to our return values across selinux_socket_getpeersec_dgram() and selinux_socket_getpeersec_stream().

Pull networking updates from Jakub Kicinski: "Core & protocols: - Large effort by Eric to lower rtnl_lock pressure and remove locks: - Make commonly used parts of rtnetlink (address, route dumps etc) lockless, protected by RCU instead of rtnl_lock. - Add a netns exit callback which already holds rtnl_lock, allowing netns exit to take rtnl_lock once in the core instead of once for each driver / callback. - Remove locks / serialization in the socket diag interface. - Remove 6 calls to synchronize_rcu() while holding rtnl_lock. - Remove the dev_base_lock, depend on RCU where necessary. - Support busy polling on a per-epoll context basis. Poll length and budget parameters can be set independently of system defaults. - Introduce struct net_hotdata, to make sure read-mostly global config variables fit in as few cache lines as possible. - Add optional per-nexthop statistics to ease monitoring / debug of ECMP imbalance problems. - Support TCP_NOTSENT_LOWAT in MPTCP. - Ensure that IPv6 temporary addresses' preferred lifetimes are long enough, compared to other configured lifetimes, and at least 2 sec. - Support forwarding of ICMP Error messages in IPSec, per RFC 4301. - Add support for the independent control state machine for bonding per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled control state machine. - Add "network ID" to MCTP socket APIs to support hosts with multiple disjoint MCTP networks. - Re-use the mono_delivery_time skbuff bit for packets which user space wants to be sent at a specified time. Maintain the timing information while traversing veth links, bridge etc. - Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets. - Simplify many places iterating over netdevs by using an xarray instead of a hash table walk (hash table remains in place, for use on fastpaths). - Speed up scanning for expired routes by keeping a dedicated list. - Speed up "generic" XDP by trying harder to avoid large allocations. - Support attaching arbitrary metadata to netconsole messages. Things we sprinkled into general kernel code: - Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena). - Rework selftest harness to enable the use of the full range of ksft exit code (pass, fail, skip, xfail, xpass). Netfilter: - Allow userspace to define a table that is exclusively owned by a daemon (via netlink socket aliveness) without auto-removing this table when the userspace program exits. Such table gets marked as orphaned and a restarting management daemon can re-attach/regain ownership. - Speed up element insertions to nftables' concatenated-ranges set type. Compact a few related data structures. BPF: - Add BPF token support for delegating a subset of BPF subsystem functionality from privileged system-wide daemons such as systemd through special mount options for userns-bound BPF fs to a trusted & unprivileged application. - Introduce bpf_arena which is sparse shared memory region between BPF program and user space where structures inside the arena can have pointers to other areas of the arena, and pointers work seamlessly for both user-space programs and BPF programs. - Introduce may_goto instruction that is a contract between the verifier and the program. The verifier allows the program to loop assuming it's behaving well, but reserves the right to terminate it. - Extend the BPF verifier to enable static subprog calls in spin lock critical sections. - Support registration of struct_ops types from modules which helps projects like fuse-bpf that seeks to implement a new struct_ops type. - Add support for retrieval of cookies for perf/kprobe multi links. - Support arbitrary TCP SYN cookie generation / validation in the TC layer with BPF to allow creating SYN flood handling in BPF firewalls. - Add code generation to inline the bpf_kptr_xchg() helper which improves performance when stashing/popping the allocated BPF objects. Wireless: - Add SPP (signaling and payload protected) AMSDU support. - Support wider bandwidth OFDMA, as required for EHT operation. Driver API: - Major overhaul of the Energy Efficient Ethernet internals to support new link modes (2.5GE, 5GE), share more code between drivers (especially those using phylib), and encourage more uniform behavior. Convert and clean up drivers. - Define an API for querying per netdev queue statistics from drivers. - IPSec: account in global stats for fully offloaded sessions. - Create a concept of Ethernet PHY Packages at the Device Tree level, to allow parameterizing the existing PHY package code. - Enable Rx hashing (RSS) on GTP protocol fields. Misc: - Improvements and refactoring all over networking selftests. - Create uniform module aliases for TC classifiers, actions, and packet schedulers to simplify creating modprobe policies. - Address all missing MODULE_DESCRIPTION() warnings in networking. - Extend the Netlink descriptions in YAML to cover message encapsulation or "Netlink polymorphism", where interpretation of nested attributes depends on link type, classifier type or some other "class type".

Pull audit updates from Paul Moore: "Two small audit patches: - Use the KMEM_CACHE() macro instead of kmem_cache_create() The guidance appears to be to use the KMEM_CACHE() macro when possible and there is no reason why we can't use the macro, so let's use it. - Remove an unnecessary assignment in audit_dupe_lsm_field() A return value variable was assigned a value in its declaration, but the declaration value is overwritten before the return value variable is ever referenced; drop the assignment at declaration time" * tag 'audit-pr-20240312' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: use KMEM_CACHE() instead of kmem_cache_create() audit: remove unnecessary assignment in audit_dupe_lsm_field()

Pull hardening updates from Kees Cook: "As is pretty normal for this tree, there are changes all over the place, especially for small fixes, selftest improvements, and improved macro usability. Some header changes ended up landing via this tree as they depended on the string header cleanups. Also, a notable set of changes is the work for the reintroduction of the UBSAN signed integer overflow sanitizer so that we can continue to make improvements on the compiler side to make this sanitizer a more viable future security hardening option. Summary: - string.h and related header cleanups (Tanzir Hasan, Andy Shevchenko) - VMCI memcpy() usage and struct_size() cleanups (Vasiliy Kovalev, Harshit Mogalapalli) - selftests/powerpc: Fix load_unaligned_zeropad build failure (Michael Ellerman) - hardened Kconfig fragment updates (Marco Elver, Lukas Bulwahn) - Handle tail call optimization better in LKDTM (Douglas Anderson) - Use long form types in overflow.h (Andy Shevchenko) - Add flags param to string_get_size() (Andy Shevchenko) - Add Coccinelle script for potential struct_size() use (Jacob Keller) - Fix objtool corner case under KCFI (Josh Poimboeuf) - Drop 13 year old backward compat CAP_SYS_ADMIN check (Jingzi Meng) - Add str_plural() helper (Michal Wajdeczko, Kees Cook) - Ignore relocations in .notes section - Add comments to explain how __is_constexpr() works - Fix m68k stack alignment expectations in stackinit Kunit test - Convert string selftests to KUnit - Add KUnit tests for fortified string functions - Improve reporting during fortified string warnings - Allow non-type arg to type_max() and type_min() - Allow strscpy() to be called with only 2 arguments - Add binary mode to leaking_addresses scanner - Various small cleanups to leaking_addresses scanner - Adding wrapping_*() arithmetic helper - Annotate initial signed integer wrap-around in refcount_t - Add explicit UBSAN section to MAINTAINERS - Fix UBSAN self-test warnings - Simplify UBSAN build via removal of CONFIG_UBSAN_SANITIZE_ALL - Reintroduce UBSAN's signed overflow sanitizer" * tag 'hardening-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (51 commits) selftests/powerpc: Fix load_unaligned_zeropad build failure string: Convert helpers selftest to KUnit string: Convert selftest to KUnit sh: Fix build with CONFIG_UBSAN=y compiler.h: Explain how __is_constexpr() works overflow: Allow non-type arg to type_max() and type_min() VMCI: Fix possible memcpy() run-time warning in vmci_datagram_invoke_guest_handler() lib/string_helpers: Add flags param to string_get_size() x86, relocs: Ignore relocations in .notes section objtool: Fix UNWIND_HINT_{SAVE,RESTORE} across basic blocks overflow: Use POD in check_shl_overflow() lib: stackinit: Adjust target string to 8 bytes for m68k sparc: vdso: Disable UBSAN instrumentation kernel.h: Move lib/cmdline.c prototypes to string.h leaking_addresses: Provide mechanism to scan binary files leaking_addresses: Ignore input device status lines leaking_addresses: Use File::Temp for /tmp files MAINTAINERS: Update LEAKING_ADDRESSES details fortify: Improve buffer overflow reporting fortify: Add KUnit tests for runtime overflows ...
