Linus Torvalds	41daf06ea1	Merge tag 'linux_kselftest-kunit-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull KUnit updates from Shuah Khan: - a new feature that adds APIs for managing devices introducing a set of helper functions which allow devices (internally a struct kunit_device) to be created and managed by KUnit. These devices will be automatically unregistered on test exit. These helpers can either use a user-provided struct device_driver, or have one automatically created and managed by KUnit. In both cases, the device lives on a new kunit_bus. - changes to switch drm/tests to use kunit devices - several fixes and enhancements to attribute feature - changes to reorganize deferred action function introducing KUNIT_DEFINE_ACTION_WRAPPER - new feature adds ability to run tests after boot using debugfs - fixes and enhancements to string-stream-test: - parse ERR_PTR in string_stream_destroy() - unchecked dereference in bug fix in debugfs_print_results() - handling errors from alloc_string_stream() - NULL-dereference bug fix in kunit_init_suite() * tag 'linux_kselftest-kunit-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: (27 commits) kunit: Fix some comments which were mistakenly kerneldoc kunit: Protect string comparisons against NULL kunit: Add example of kunit_activate_static_stub() with pointer-to-function kunit: Allow passing function pointer to kunit_activate_static_stub() kunit: Fix NULL-dereference in kunit_init_suite() if suite->log is NULL kunit: Reset test->priv after each param iteration kunit: Add example for using test->priv drm/tests: Switch to kunit devices ASoC: topology: Replace fake root_device with kunit_device in tests overflow: Replace fake root_device with kunit_device fortify: test: Use kunit_device kunit: Add APIs for managing devices Documentation: Add debugfs docs with run after boot kunit: add ability to run tests after boot using debugfs kunit: add is_init test attribute kunit: add example suite to test init suites kunit: add KUNIT_INIT_TABLE to init linker section kunit: move KUNIT_TABLE out of INIT_DATA kunit: tool: add test for parsing attributes kunit: tool: fix parsing of test attributes ...	2024-01-09 17:16:58 -08:00

Linus Torvalds	7da71072e1	Merge tag 'pm-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "These add support for new processors (Sierra Forest, Grand Ridge and Meteor Lake) to the intel_idle driver, make intel_pstate run on Emerald Rapids without HWP support and adjust it to utilize EPP values supplied by the platform firmware, fix issues, clean up code and improve documentation. The most significant fix addresses deadlocks in the core system-wide resume code that occur if async_schedule_dev() attempts to run its argument function synchronously (for example, due to a memory allocation failure). It rearranges the code in question which may increase the system resume time in some cases, but this basically is a removal of a premature optimization. That optimization will be added back later, but properly this time. Specifics: - Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui) - Do not enable interrupts when entering idle in the haltpoll cpuidle driver (Borislav Petkov) - Add Emerald Rapids support in no-HWP mode to the intel_pstate cpufreq driver (Zhenguo Yao) - Use EPP values programmed by the platform firmware as balanced performance ones by default in intel_pstate (Srinivas Pandruvada) - Add a missing function return value check to the SCMI cpufreq driver to avoid unexpected behavior (Alexandra Diupina) - Fix parameter type warning in the armada-8k cpufreq driver (Gregory CLEMENT) - Rework trans_stat_show() in the devfreq core code to avoid buffer overflows (Christian Marangi) - Synchronize devfreq_monitor_[start/stop] so as to prevent a timer list corruption from occurring when devfreq governors are switched frequently (Mukesh Ojha) - Fix possible deadlocks in the core system-wide PM code that occur if device-handling functions cannot be executed asynchronously during resume from system-wide suspend (Rafael J.

Linus Torvalds	7f73ba68cf	Merge tag 'thermal-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull thermal control updates from Rafael Wysocki: "These add support for the D1/T113s THS controller to the sun8i driver and a DT-based mechanism for platforms to indicate a preference to reboot (instead of shutting down) on crossing a critical trip point, fix issues, make other improvements (in the IPA governor, the Intel HFI driver, the exynos driver and the thermal netlink interface among other places) and clean up code. One long-standing issue addressed here is that trip point crossing notifications sent to user space might be unreliable due to the incorrect handling of trip point hysteresis in the thermal core: multiple notifications might be sent for the same event or there might be events without any notification at all. Specifics: - Add dynamic thresholds for trip point crossing detection to prevent trip point crossing notifications from being sent at incorrect times or not at all in some cases (Rafael J. Wysocki) - Fix synchronization issues related to the resume of thermal zones during a system-wide resume and allow thermal zones to be resumed concurrently (Rafael J. Wysocki) - Modify the thermal zone unregistration to wait for the given zone to go away completely before returning to the caller and rework the sysfs interface for trip points on top of that (Rafael J. Wysocki) - Fix a possible NULL pointer dereference in thermal zone registration error path (Rafael J.

Linus Torvalds	bd012f3a5b	Merge tag 'acpi-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI updates from Rafael Wysocki: "From the new features standpoint, the most significant change here is the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI device enumeration code that will allow MIPI cameras to be enumerated through the platform firmware on systems using ACPI. Also significant is the switch-over to threaded interrupt handlers for the ACPI SCI and the dedicated EC interrupt (on systems where the former is not used) which essentially allows all ACPI code to run with local interrupts enabled. That should improve responsiveness significantly on systems where multiple GPEs are enabled and the handling of one SCI involves many I/O address space accesses which previously had to be carried out in one go with disabled interrupts on the local CPU. Apart from the above, the ACPI thermal zone driver will use the Thermal fast Sampling Period (_TFP) object if available, which should allow temperature changes to be followed more accurately on some systems, the ACPI Notify () handlers can run on all CPUs (not just on CPU0), which should generally speed up the processing of events signaled through the ACPI SCI, and the ACPI power button driver will trigger wakeup key events via the input subsystem (on systems where it is a system wakeup device) In addition to that, there are the usual bunch of fixes and cleanups. Specifics: - Add CSI-2 and DisCo for Imaging support to the ACPI device enumeration code (Sakari Ailus, Rafael J. Wysocki) - Adjust the cpufreq thermal reduction algorithm in the ACPI processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd Bergmann) - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki) - Switch over ACPI to using a threaded interrupt handler for the SCI (Rafael J. Wysocki) - Allow ACPI Notify () handlers to run on all CPUs and clean up the ACPI interface for deferred events processing (Rafael J. Wysocki) - Switch over the ACPI EC driver to using a threaded handler for the dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki) - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock to keep local interrupts on (Rafael J. Wysocki) - Adjust the USB4 _OSC handshake to correctly handle cases in which certain types of OS control are denied by the platform (Mika Westerberg) - Correct and clean up the generic function for parsing ACPI data-only tables with array structure (Yuntao Wang) - Modify acpi_dev_uid_match() to support different types of its second argument and adjust its users accordingly (Raag Jadav) - Clean up code related to acpi_evaluate_reference() and ACPI device lists (Rafael J. Wysocki) - Use generic ACPI helpers for evaluating trip point temperature objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd Bergmann) - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal zone driver (Jeff Brasen) - Modify the ACPI LPIT table handling code to avoid u32 multiplication overflows in state residency computations (Nikita Kiryushin) - Drop an unused helper function from the ACPI backlight (video) driver and add a clarifying comment to it (Hans de Goede) - Update the ACPI backlight driver to avoid using uninitialized memory in some cases (Nikita Kiryushin) - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo Qiu) - Add support for vendor-defined error types to the ACPI APEI error injection code (Avadhut Naik) - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous memory failure events, so they are handled differently from the asynchronous ones (Shuai Xue) - Fix NULL pointer dereference check in the ACPI extlog driver (Prarit Bhargava) - Adjust the ACPI extlog driver to clear the Extended Error Log status when RAS_CEC handled the error (Tony Luck) - Add IRQ override quirks for some Infinity laptops and for TongFang GMxXGxx (David McFarland, Hans de Goede) - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is not the same as one of the real pxm values (Yuntao Wang) - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC) driver so as to prevent miscalculation of the values in the clock divider (Andy Shevchenko) - Adjust comments in the ACPI watchdog driver to prevent kernel-doc from complaining during documentation builds (Randy Dunlap) - Make the ACPI button driver send wakeup key events to user space in addition to power button events on systems that can be woken up by the power button (Ken Xue) - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full structure field (Dmitry Antipov)" * tag 'acpi-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (56 commits) ACPI: resource: Add Infinity laptops to irq1_edge_low_force_override ACPI: button: trigger wakeup key events ACPI: resource: Add another DMI match for the TongFang GMxXGxx ACPI: EC: Use a spin lock without disabing interrupts ACPI: EC: Use a threaded handler for dedicated IRQ ACPI: OSL: Use spin locks without disabling interrupts ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on synchronous events ACPI: utils: Introduce helper for _DEP list lookup ACPI: utils: Fix white space in struct acpi_handle_list definition ACPI: utils: Refine acpi_handle_list_equal() slightly ACPI: utils: Return bool from acpi_evaluate_reference() ACPI: utils: Rearrange in acpi_evaluate_reference() ACPI: arm64: export acpi_arch_thermal_cpufreq_pctg() ACPI: extlog: Clear Extended Error Log status when RAS_CEC handled the error ACPI: LPSS: Fix the fractional clock divider flags ACPI: NUMA: Fix the logic of getting the fake_pxm value ACPI: NUMA: Optimize the check for the availability of node values ACPI: NUMA: Remove unnecessary check in acpi_parse_gi_affinity() ACPI: watchdog: fix kernel-doc warnings ACPI: extlog: fix NULL pointer dereference check ...	2024-01-09 16:12:44 -08:00

Linus Torvalds	063a7ce32d	Merge tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm Pull security module updates from Paul Moore: - Add three new syscalls: lsm_list_modules(), lsm_get_self_attr(), and lsm_set_self_attr(). The first syscall simply lists the LSMs enabled, while the second and third get and set the current process' LSM attributes. Yes, these syscalls may provide similar functionality to what can be found under /proc or /sys, but they were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time. We have spent considerable time discussing ways to extend the existing /proc interfaces to support multiple, simultaneaous LSMs and even our best ideas have been far too ugly to support as a kernel API; after +20 years in the kernel, I felt the LSM layer had established itself enough to justify a handful of syscalls. Support amongst the individual LSM developers has been nearly unanimous, with a single objection coming from Tetsuo (TOMOYO) as he is worried that the LSM_ID_XXX token concept will make it more difficult for out-of-tree LSMs to survive. Several members of the LSM community have demonstrated the ability for out-of-tree LSMs to continue to exist by picking high/unused LSM_ID values as well as pointing out that many kernel APIs rely on integer identifiers, e.g. syscalls (!), but unfortunately Tetsuo's objections remain. My personal opinion is that while I have no interest in penalizing out-of-tree LSMs, I'm not going to penalize in-tree development to support out-of-tree development, and I view this as a necessary step forward to support the push for expanded LSM stacking and reduce our reliance on /proc and /sys which has occassionally been problematic for some container users. Finally, we have included the linux-api folks on (all?) recent revisions of the patchset and addressed all of their concerns. - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit ioctls on 64-bit systems problem. This patch includes support for all of the existing LSMs which provide ioctl hooks, although it turns out only SELinux actually cares about the individual ioctls. It is worth noting that while Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this patch, they did both indicate they are okay with the changes. - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled at boot. While it's good that we are fixing this, I doubt this is something users are seeing in the wild as you need to both disable IPv6 and then attempt to configure IPv6 labeled networking via NetLabel/CALIPSO; that just doesn't make much sense. Normally this would go through netdev, but Jakub asked me to take this patch and of all the trees I maintain, the LSM tree seemed like the best fit. - Update the LSM MAINTAINERS entry with additional information about our process docs, patchwork, bug reporting, etc. I also noticed that the Lockdown LSM is missing a dedicated MAINTAINERS entry so I've added that to the pull request. I've been working with one of the major Lockdown authors/contributors to see if they are willing to step up and assume a Lockdown maintainer role; hopefully that will happen soon, but in the meantime I'll continue to look after it. - Add a handful of mailmap entries for Serge Hallyn and myself. * tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (27 commits) lsm: new security_file_ioctl_compat() hook lsm: Add a __counted_by() annotation to lsm_ctx.ctx calipso: fix memory leak in netlbl_calipso_add_pass() selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test MAINTAINERS: add an entry for the lockdown LSM MAINTAINERS: update the LSM entry mailmap: add entries for Serge Hallyn's dead accounts mailmap: update/replace my old email addresses lsm: mark the lsm_id variables are marked as static lsm: convert security_setselfattr() to use memdup_user() lsm: align based on pointer length in lsm_fill_user_ctx() lsm: consolidate buffer size handling into lsm_fill_user_ctx() lsm: correct error codes in security_getselfattr() lsm: cleanup the size counters in security_getselfattr() lsm: don't yet account for IMA in LSM_CONFIG_COUNT calculation lsm: drop LSM_ID_IMA LSM: selftests for Linux Security Module syscalls SELinux: Add selfattr hooks AppArmor: Add selfattr hooks Smack: implement setselfattr and getselfattr hooks ...	2024-01-09 12:57:46 -08:00

Linus Torvalds	d30e51aa7b	Merge tag 'slab-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab Pull slab updates from Vlastimil Babka: - SLUB: delayed freezing of CPU partial slabs (Chengming Zhou) Freezing is an operation involving double_cmpxchg() that makes a slab exclusive for a particular CPU. Chengming noticed that we use it also in situations where we are not yet installing the slab as the CPU slab, because freezing also indicates that the slab is not on the shared list. This results in redundant freeze/unfreeze operation and can be avoided by marking separately the shared list presence by reusing the PG_workingset flag. This approach neatly avoids the issues described in `9b1ea29bc0` ("Revert "mm, slub: consider rest of partial list if acquire_slab() fails"") as we can now grab a slab from the shared list in a quick and guaranteed way without the cmpxchg_double() operation that amplifies the lock contention and can fail. As a result, lkp has reported 34.2% improvement of stress-ng.rawudp.ops_per_sec - SLAB removal and SLUB cleanups (Vlastimil Babka) The SLAB allocator has been deprecated since 6.5 and nobody has objected so far. We agreed at LSF/MM to wait until the next LTS, which is 6.6, so we should be good to go now. This doesn't yet erase all traces of SLAB outside of mm/ so some dead code, comments or documentation remain, and will be cleaned up gradually (some series are already in the works). Removing the choice of allocators has already allowed to simplify and optimize the code wiring up the kmalloc APIs to the SLUB implementation. * tag 'slab-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: (34 commits) mm/slub: free KFENCE objects in slab_free_hook() mm/slub: handle bulk and single object freeing separately mm/slub: introduce __kmem_cache_free_bulk() without free hooks mm/slub: fix bulk alloc and free stats mm/slub: optimize free fast path code layout mm/slub: optimize alloc fastpath code layout mm/slub: remove slab_alloc() and __kmem_cache_alloc_lru() wrappers mm/slab: move kmalloc() functions from slab_common.c to slub.c mm/slab: move kmalloc_slab() to mm/slab.h mm/slab: move kfree() from slab_common.c to slub.c mm/slab: move struct kmem_cache_node from slab.h to slub.c mm/slab: move memcg related functions from slab.h to slub.c mm/slab: move pre/post-alloc hooks from slab.h to slub.c mm/slab: consolidate includes in the internal mm/slab.h mm/slab: move the rest of slub_def.h to mm/slab.h mm/slab: move struct kmem_cache_cpu declaration to slub.c mm/slab: remove mm/slab.c and slab_def.h mm/mempool/dmapool: remove CONFIG_DEBUG_SLAB ifdefs mm/slab: remove CONFIG_SLAB code from slab common code cpu/hotplug: remove CPUHP_SLAB_PREPARE hooks ...	2024-01-09 10:36:07 -08:00

While cgroup1 is mostly in maintenance mode, this addition is very small while having an outsized usefulness for users who are still on cgroup1. Yafang also optimized root cgroup list access by making it RCU protected in the process. - Waiman Long optimized rstat operation leading to substantially lower and more consistent lock hold time while flushing the hierarchical statistics. As the lock can be acquired briefly in various hot paths, this reduction has cascading benefits. - Waiman also improved the quality of isolation for cpuset's isolated partitions. CPUs which are allocated to isolated partitions are now excluded from running unbound work items and cpu_is_isolated() test which is used by vmstat and memcg to reduce interference now includes cpuset isolated CPUs.

Roughly, a new permission event will be added indicating that it is safe to write to the file being accessed. These events are used by hierarchical storage managers to e.g., fill the content of files on first access. During that work we noticed that our current permission checking is inconsistent in rw_verify_area() and remap_verify_area(). Especially in the splice code permission checking is done multiple times. For example, one time for the whole range and then again for partial ranges inside the iterator. In addition, we mostly do permission checking before we call file_start_write() except for a few places where we call it after. For pre-content events we need such permission checking to be done before file_start_write(). So this is a nice reason to clean this all up. After this series, all permission checking is done before file_start_write(). As part of this cleanup we also massaged the splice code a bit. We got rid of a few helpers because we are alredy drowning in special read-write helpers. We also cleaned up the return types for splice helpers. - Introduce generic read-write helpers for backing files.

Linus Torvalds	8c9440fea7	Merge tag 'vfs-6.8.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs mount updates from Christian Brauner: "This contains the work to retrieve detailed information about mounts via two new system calls. This is hopefully the beginning of the end of the saga that started with fsinfo() years ago. The LWN articles in [1] and [2] can serve as a summary so we can avoid rehashing everything here. At LSFMM in May 2022 we got into a room and agreed on what we want to do about fsinfo(). Basically, split it into pieces. This is the first part of that agreement. Specifically, it is concerned with retrieving information about mounts. So this only concerns the mount information retrieval, not the mount table change notification, or the extended filesystem specific mount option work. That is separate work. Currently mounts have a 32bit id. Mount ids are already in heavy use by libmount and other low-level userspace but they can't be relied upon because they're recycled very quickly. We agreed that mounts should carry a unique 64bit id by which they can be referenced directly. This is now implemented as part of this work. The new 64bit mount id is exposed in statx() through the new STATX_MNT_ID_UNIQUE flag. If the flag isn't raised the old mount id is returned. If it is raised and the kernel supports the new 64bit mount id the flag is raised in the result mask and the new 64bit mount id is returned. New and old mount ids do not overlap so they cannot be conflated. Two new system calls are introduced that operate on the 64bit mount id: statmount() and listmount(). A summary of the api and usage can be found on LWN as well (cf. [3]) but of course, I'll provide a summary here as well. Both system calls rely on struct mnt_id_req. Which is the request struct used to pass the 64bit mount id identifying the mount to operate on. It is extensible to allow for the addition of new parameters and for future use in other apis that make use of mount ids. statmount() mimicks the semantics of statx() and exposes a set flags that userspace may raise in mnt_id_req to request specific information to be retrieved. A statmount() call returns a struct statmount filled in with information about the requested mount. Supported requests are indicated by raising the request flag passed in struct mnt_id_req in the @mask argument in struct statmount. Currently we do support: - STATMOUNT_SB_BASIC: Basic filesystem info - STATMOUNT_MNT_BASIC Mount information (mount id, parent mount id, mount attributes etc) - STATMOUNT_PROPAGATE_FROM Propagation from what mount in current namespace - STATMOUNT_MNT_ROOT Path of the root of the mount (e.g., mount --bind /bla /mnt returns /bla) - STATMOUNT_MNT_POINT Path of the mount point (e.g., mount --bind /bla /mnt returns /mnt) - STATMOUNT_FS_TYPE Name of the filesystem type as the magic number isn't enough due to submounts The string options STATMOUNT_MNT_{ROOT,POINT} and STATMOUNT_FS_TYPE are appended to the end of the struct. Userspace can use the offsets in @fs_type, @mnt_root, and @mnt_point to reference those strings easily. The struct statmount reserves quite a bit of space currently for future extensibility. This isn't really a problem and if this bothers us we can just send a follow-up pull request during this cycle. listmount() is given a 64bit mount id via mnt_id_req just as statmount(). It takes a buffer and a size to return an array of the 64bit ids of the child mounts of the requested mount. Userspace can thus choose to either retrieve child mounts for a mount in batches or iterate through the child mounts. For most use-cases it will be sufficient to just leave space for a few child mounts. But for big mount tables having an iterator is really helpful. Iterating through a mount table works by setting @param in mnt_id_req to the mount id of the last child mount retrieved in the previous listmount() call" Link: https://lwn.net/Articles/934469 [1] Link: https://lwn.net/Articles/829212 [2] Link: https://lwn.net/Articles/950569 [3] * tag 'vfs-6.8.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: add selftest for statmount/listmount fs: keep struct mnt_id_req extensible wire up syscalls for statmount/listmount add listmount(2) syscall statmount: simplify string option retrieval statmount: simplify numeric option retrieval add statmount(2) syscall namespace: extract show_path() helper mounts: keep list of mounts in an rbtree add unique mount ID	2024-01-08 10:57:34 -08:00

Furthermore syzbot comes with more and more involved examples how to corrupt block device under a mounted filesystem leading to kernel crashes and reports we can do nothing about. Add tracking of writers to each block device and a kernel cmdline argument which controls whether other writeable opens to block devices open with BLK_OPEN_RESTRICT_WRITES flag are allowed. Note that this effectively only prevents modification of the particular block device's page cache by other writers. The actual device content can still be modified by other means - e.g. by issuing direct scsi commands, by doing writes through devices lower in the storage stack (e.g. in case loop devices, DM, or MD are involved) etc. But blocking direct modifications of the block device page cache is enough to give filesystems a chance to perform data validation when loading data from the underlying storage and thus prevent kernel crashes. Syzbot can use this cmdline argument option to avoid uninteresting crashes. Also users whose userspace setup does not need writing to mounted block devices can set this option for hardening. We expect that this will be interesting to quite a few workloads. Btrfs is currently opted out of this because they still haven't merged patches we require for this to work from three kernel releases ago. - Reimplement block device freezing and thawing as holder operations on the block device. This allows us to extend block device freezing to all devices associated with a superblock and not just the main device. It also allows us to remove get_active_super() and thus another function that scans the global list of superblocks. Freezing via additional block devices only works if the filesystem chooses to use @fs_holder_ops for these additional devices as well. That currently only includes ext4 and xfs. Earlier releases switched get_tree_bdev() and mount_bdev() to use @fs_holder_ops. The remaining nilfs2 open-coded version of mount_bdev() has been converted to rely on @fs_holder_ops as well. So block device freezing for the main block device will continue to work as before. There should be no regressions in functionality. The only special case is btrfs where block device freezing for the main block device never worked because sb->s_bdev isn't set. Block device freezing for btrfs can be fixed once they can switch to @fs_holder_ops but that can happen whenever they're ready" * tag 'vfs-6.8.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (27 commits) block: Fix a memory leak in bdev_open_by_dev() super: don't bother with WARN_ON_ONCE() super: massage wait event mechanism ext4: Block writes to journal device xfs: Block writes to log device fs: Block writes to mounted block devices btrfs: Do not restrict writes to btrfs devices block: Add config option to not allow writing to mounted devices block: Remove blkdev_get_by_*() functions bcachefs: Convert to bdev_open_by_path() fs: handle freezing from multiple devices fs: remove dead check nilfs2: simplify device handling fs: streamline thaw_super_locked ext4: simplify device handling xfs: simplify device handling fs: simplify setup_bdev_super() calls blkdev: comment fs_holder_ops porting: document block device freeze and thaw changes fs: remove unused helper ...	2024-01-08 10:43:51 -08:00

This series is the result of the following discussion: https://lore.kernel.org/47066176-bd93-55dd-c2fa-002299d9e034@linux.ibm.com/ It mainly avoids building the code that walks page tables on CPUs that use it, i.e., those don't support hardware accessed bit. Specifically, it introduces a new Kconfig to guard some of functions added by commit `bd74fdaea1` ("mm: multi-gen LRU: support page table walks") on CPUs like POWER9, on which the series was tested. This patch (of 5): Some architectures are able to set the accessed bit in PTEs when PTEs are used as part of linear address translations. Add CONFIG_ARCH_HAS_HW_PTE_YOUNG for such architectures to be able to override arch_has_hw_pte_young().

David Hildenbrand	9c5938694c	mm/rmap: silence VM_WARN_ON_FOLIO() in __folio_rmap_sanity_checks() Unfortunately, vm_insert_page() and friends and up passing driver-allocated folios into folio_add_file_rmap_pte() using insert_page_into_pte_locked(). While these driver-allocated folios can be compound pages (large folios), they are not proper "rmappable" folios. In these VM_MIXEDMAP VMAs, there isn't really the concept of a reverse mapping, so long-term, we should clean that up and not call into rmap code. For the time being, document how we can end up in rmap code with large folios that are not marked rmappable.

Dmitry Safonov	4c8530dc7d	net/tcp: Only produce AO/MD5 logs if there are any keys User won't care about inproper hash options in the TCP header if they don't use neither TCP-AO nor TCP-MD5. Yet, those logs can add up in syslog, while not being a real concern to the host admin: > kernel: TCP: TCP segment has incorrect auth options set for XX.20.239.12.54681->XX.XX.90.103.80 [S] Keep silent and avoid logging when there aren't any keys in the system. Side-note: I also defined static_branch_tcp_*() helpers to avoid more ifdeffery, going to remove more ifdeffery further with their help.
