Linus Torvalds	1b98f357da	Merge tag 'net-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next ... Pull networking updates from Paolo Abeni: "Core: - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster. - Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability. - Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks. - Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests. - Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT. - Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages. Netfilter: - Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface. - Implement support for wildcard netdevice in netdev basechain and flowtables. - Integrate conntrack information into nft trace infrastructure. - Export set count and backend name to userspace, for better introspection. BPF: - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command. - Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets. Protocols: - Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%. - Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server. - Improve TCP multipath routing, so that the sources address always matches the nexthop device. - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs. - Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. - Extend TCP drop-reason support to cover PAWS checks. Driver API: - Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags. - Converted several device drivers to timestamping APIs. - Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs. Tests and tooling: - Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration. - Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output. - Extend MPTCP selftests to improve the code-coverage. - Add tests for XDP tail adjustment in AF_XDP. New hardware / drivers: - OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation. - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC. - Broadcom asp-v3.0 ethernet driver. - AMD Renoir ethernet device. - ReakTek MT9888 2.5G ethernet PHY driver. - Aeonsemi 10G C45 PHYs driver.

Pull arm64 updates from Will Deacon: "The headline feature is the re-enablement of support for Arm's Scalable Matrix Extension (SME) thanks to a bumper crop of fixes from Mark Rutland. If matrices aren't your thing, then Ryan's page-table optimisation work is much more interesting.

Linus Torvalds	3b66e6b3c0	Merge tag 'cgroup-for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup ... Pull cgroup updates from Tejun Heo: - cgroup rstat shared the tracking tree across all controllers with the rationale being that a cgroup which is using one resource is likely to be using other resources at the same time (ie. if something is allocating memory, it's probably consuming CPU cycles). However, this turned out to not scale very well especially with memcg using rstat for internal operations which made memcg stat read and flush patterns substantially different from other controllers.

Linus Torvalds	c89756bcf4	Merge tag 'pm-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm ... Pull power management updates from Rafael Wysocki: "Once again, the changes are dominated by cpufreq updates, but this time the majority of them are cpufreq core changes, mostly related to the introduction of policy locking guards and __free() usage, and fixes related to boost handling. Still, there is also a significant update of the intel_pstate driver making it register an energy model when running on a hybrid platform which is used for enabling energy-aware scheduling (EAS) if the driver operates in the passive mode (and schedutil is used as the cpufreq governor for all CPUs which is the passive mode default). There are some amd-pstate driver updates too, for a good measure, including the "Requested CPU Min frequency" BIOS option support and new online/offline callbacks. In the cpuidle space, the most significant change is the addition of a C1 demotion on/off sysfs knob to intel_idle which should help some users to configure their systems more precisely. There is also the conversion of the PSCI cpuidle driver to a faux device one and there are two small updates of cpuidle governors. Device power management is also modified quite a bit, especially the handling of devices with asynchronous suspend and resume enabled during system transitions. They are now going to be handled more asynchronously during suspend transitions and somewhat less aggressively during resume transitions. Apart from the above, the operating performance points (OPP) library is now going to use mutex locking guards and scope-based cleanup helpers and there is the usual bunch of assorted fixes and code cleanups. Specifics: - Fix potential division-by-zero error in em_compute_costs() (Yaxiong Tian) - Fix typos in energy model documentation and example driver code (Moon Hee Lee, Atul Kumar Pant) - Rearrange the energy model management code and add a new function for adjusting a CPU energy model after adjusting the capacity of the given CPU to it (Rafael Wysocki) - Refactor cpufreq_online(), add and use cpufreq policy locking guards, use __free() in policy reference counting, and clean up core cpufreq code on top of that (Rafael Wysocki) - Fix boost handling on CPU suspend/resume and sysfs updates (Viresh Kumar) - Fix des_perf clamping with max_perf in amd_pstate_update() (Dhananjay Ugwekar) - Add offline, online and suspend callbacks to the amd-pstate driver, rename and use the existing amd_pstate_epp callbacks in it (Dhananjay Ugwekar) - Add support for the "Requested CPU Min frequency" BIOS option to the amd-pstate driver (Dhananjay Ugwekar) - Reset amd-pstate driver mode after running selftests (Swapnil Sapkal) - Avoid shadowing ret in amd_pstate_ut_check_driver() (Nathan Chancellor) - Add helper for governor checks to the schedutil cpufreq governor and move cpufreq-specific EAS checks to cpufreq (Rafael Wysocki) - Populate the cpu_capacity sysfs entries from the intel_pstate driver after registering asym capacity support (Ricardo Neri) - Add support for enabling Energy-aware scheduling (EAS) to the intel_pstate driver when operating in the passive mode on a hybrid platform (Rafael Wysocki) - Drop redundant cpus_read_lock() from store_local_boost() in the cpufreq core (Seyediman Seyedarab) - Replace sscanf() with kstrtouint() in the cpufreq code and use a symbol instead of a raw number in it (Bowen Yu) - Add support for autonomous CPU performance state selection to the CPPC cpufreq driver (Lifeng Zheng) - OPP: Add dev_pm_opp_set_level() (Praveen Talari) - Introduce scope-based cleanup headers and mutex locking guards in OPP core (Viresh Kumar) - Switch OPP to use kmemdup_array() (Zhang Enpei) - Optimize bucket assignment when next_timer_ns equals KTIME_MAX in the menu cpuidle governor (Zhongqiu Han) - Convert the cpuidle PSCI driver to a faux device one (Sudeep Holla) - Add C1 demotion on/off sysfs knob to the intel_idle driver (Artem Bityutskiy) - Fix typos in two comments in the teo cpuidle governor (Atul Kumar Pant) - Fix denying of auto suspend in pm_suspend_timer_fn() (Charan Teja Kalla) - Move debug runtime PM attributes to runtime_attrs[] (Rafael Wysocki) - Add new devm_ functions for enabling runtime PM and runtime PM reference counting (Bence Csókás) - Remove size arguments from strscpy() calls in the hibernation core code (Thorsten Blum) - Adjust the handling of devices with asynchronous suspend enabled during system suspend and resume to start resuming them immediately after resuming their parents and to start suspending such a device immediately after suspending its first child (Rafael Wysocki) - Adjust messages printed during tasks freezing to avoid using pr_cont() (Andrew Sayers, Paul Menzel) - Clean up unnecessary usage of !! in pm_print_times_init() (Zihuan Zhang) - Add missing wakeup source attribute relax_count to sysfs and remove the space character at the end ofi the string produced by pm_show_wakelocks() (Zijun Hu) - Add configurable pm_test delay for hibernation (Zihuan Zhang) - Disable asynchronous suspend in ucsi_ccg_probe() to prevent the cypd4226 device on Tegra boards from suspending prematurely (Jon Hunter) - Unbreak printing PM debug messages during hibernation and clean up some related code (Rafael Wysocki) - Add a systemd service to run cpupower and change cpupower binding's Makefile to use -lcpupower (John B.

The treewide conversion of GPIO drivers to using the new value setter callbacks is ongoing with another round of GPIO drivers updated. You will also see these commits coming in from other subsystems as with the relevant changes merged into mainline last cycle, I've started converting GPIO providers located elsewhere than drivers/gpio/. GPIO core: - use more lock guards where applicable - refactor GPIO ACPI code and shrink it in the process by 8% - move GPIO ACPI quirks into a separate file - remove unneeded #ifdef - convert GPIO devres helpers to using devm_add_action() where applicable which shrinks and simplifies the code - refactor GPIO descriptor validation in GPIO consumer interfaces - don't allow setting values on input lines in the GPIO core which will take off the burden from GPIO drivers of checking this down the line - provide gpiod_is_equal() as a way of safely comparing two GPIO descriptors (the only current user is in regulator core) New drivers: - add the GPIO module for the max77759 multifunction device - add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller - add the GPIO driver for the Spacemit K1 SoC Driver improvements: - convert more drivers to using the new GPIO line value setter callbacks - convert more drivers to making the irq_chip immutable as is recommended by the interrupt subsystem - extend build testing coverage by enabling more modules to be built with COMPILE_TEST=y - extend the gpio-aggregator module with a configfs interface that makes the setup easier for user-space than the existing driver-level sysfs attributes and also adds more advanced configuration features (such as referring to aggregated lines by their original names or modifying their names as exposed by the aggregated chip) - add a missing mutex_destroy() in gpio-imx-scu - add an OF polarity quirk for s5m8767 - allow building gpio-vf610 as a loadable module - make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS interface disabled (another small step towards getting rid of the global GPIO numberspace) - add support for level-triggered interrupts to gpio-pca953x - don't double-check the ngpios property in gpio-ds4520 as GPIO core already does it - don't double-check the number of GPIOs in gpio-imx-scu as GPIO core already does it - remove unused callbacks from gpio-max3191x DT bindings: - add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new drivers added this cycle) - document more properties for gpio-vf610 and gpio-tegra186 - document a new pca95xx variant - fix style of examples in several GPIO DT-binding documents Misc: - TODO list updates" * tag 'gpio-updates-for-v6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (123 commits) gpio: timberdale: select GPIOLIB_IRQCHIP gpio: lpc18xx: select GPIOLIB_IRQCHIP gpio: grgpio: select GPIOLIB_IRQCHIP gpio: bcm-kona: select GPIOLIB_IRQCHIP dt-bindings: gpio: vf610: add ngpios and gpio-reserved-ranges gpio: davinci: select GPIOLIB_IRQCHIP gpiolib-acpi: Update file references in the Documentation and MAINTAINERS gpiolib: acpi: Move quirks to a separate file gpiolib: acpi: Add acpi_gpio_need_run_edge_events_on_boot() getter gpiolib: acpi: Handle deferred list via new API gpiolib: acpi: Make sure we fill struct acpi_gpio_info gpiolib: acpi: Switch to use enum in acpi_gpio_in_ignore_list() gpiolib: acpi: Use temporary variable for struct acpi_gpio_info gpiolib: remove unneeded #ifdef gpio: mpc8xxx: select GPIOLIB_IRQCHIP gpio: pxa: select GPIOLIB_IRQCHIP gpio: pxa: Make irq_chip immutable gpio: timberdale: Make irq_chip immutable gpio: xgene-sb: Make irq_chip immutable gpio: davinci: Make irq_chip immutable ...	2025-05-27 15:22:01 -07:00

People will never understand that APIs exist for a reason... - Provide core infrastructre for the upcoming PCI endpoint library extensions. Currently limited to ARM GICv3+, but in theory extensible to other architectures. - Provide a MSI domain::teardown() callback, which allows drivers to undo the effects of the prepare() callback. - Move the MSI domain::prepare() callback invocation to domain creation time to avoid redundant (and in case of ARM/GIC-V3-ITS confusing) invocations on every allocation. In combination with the new teardown callback this removes some ugly hacks in the GIC-V3-ITS driver, which pretended to work around the short comings of the core code so far. With this update the code is correct by design and implementation. - Make the irqchip MSI library globally available, provide a MSI parent domain creation helper and convert a bunch of (PCI/)MSI drivers over to the modern MSI parent mechanism.

It should have been obvious at the time that this was a | bad idea, given the need to sprinkle fixup_pointer() calls left and | right to manipulate global variables (including non-pointer variables) | without crashing. | | This C startup code has been expanding, and in particular, the SEV-SNP | startup code has been expanding over the past couple of years, and | grown many of these warts, where the C code needs to use special | annotations or helpers to access global objects.

Linus Torvalds	522544fc71	Merge tag 'bcachefs-2025-05-24' of git://evilpiepirate.org/bcachefs ... Pull bcachefs updates from Kent Overstreet: - Poisoned extents can now be moved: this lets us handle bitrotted data without deleting it. For now, reading from poisoned extents only returns -EIO: in the future we'll have an API for specifying "read this data even if there were bitflips". - Incompatible features may now be enabled at runtime, via "opts/version_upgrade" in sysfs. Toggle it to incompatible, and then toggle it back - option changes via the sysfs interface are persistent. - Various changes to support deployable disk images: - RO mounts now use less memory - Images may be stripped of alloc info, particularly useful for slimming them down if they will primarily be mounted RO. Alloc info will be automatically regenerated on first RW mount, and this is quite fast - Filesystem images generated with 'bcachefs image' will be automatically resized the first time they're mounted on a larger device The images 'bcachefs image' generates with compression enabled have been comparable in size to those generated by squashfs and erofs - but you get a full RW capable filesystem - Major error message improvements for btree node reads, data reads, and elsewhere. We now build up a single error message that lists all the errors encountered, actions taken to repair, and success/failure of the IO. This extends to other error paths that may kick off other actions, e.g. scheduling recovery passes: actions we took because of an error are included in that error message, with grouping/indentation so we can see what caused what. - New option, 'rebalance_on_ac_only'. Does exactly what the name suggests, quite handy with background compression. - Repair/self healing: - We can now kick off recovery passes and run them in the background if we detect errors. Currently, this is just used by code that walks backpointers. We now also check for missing backpointers at runtime and run check_extents_to_backpointers if required. The messy 6.14 upgrade left missing backpointers for some users, and this will correct that automatically instead of requiring a manual fsck - some users noticed this as copygc spinning and not making progress. In the future, as more recovery passes come online, we'll be able to repair and recover from nearly anything - except for unreadable btree nodes, and that's why you're using replication, of course - without shutting down the filesystem. - There's a new recovery pass, for checking the rebalance_work btree, which tracks extents that rebalance will process later. - Hardening: - Close the last known hole in btree iterator/btree locking assertions: path->should_be_locked paths must stay locked until the end of the transaction. This shook out a few bugs, including a performance issue that was causing unnecessary path_upgrade transaction restarts. - Performance: - Faster snapshot deletion: this is an incompatible feature, as it requires new sentinal values, for safety. Snapshot deletion no longer has to do a full metadata scan, it now just scans the inodes btree: if an extent/dirent/xattr is present for a given snapshot ID, we already require that an inode be present with that same snapshot ID. If/when users hit scalability limits again (ridiculously huge filesystems with lots of inodes, and many sparse snapshots), let me know - the next step will be to add an index from snapshot ID -> inode number, which won't be too hard. - Faster device removal: the "scan for pointers to this device" no longer does a full metadata scan, instead it walks backpointers. Like fast snapshot deletion this is another incompat feature: it also requires a new sentinal value, because we don't want to reuse these device IDs until after a fsck. - We're now coalescing redundant accounting updates prior to transaction commit, taking some pressure off the journal. Shortly we'll also be doing multiple extent updates in a transaction in the main write path, which combined with the previous should drastically cut down on the amount of metadata updates we have to journal. - Stack usage improvements: All allocator state has been moved off the stack - Debug improvements: - enumerated refcounts: The debug code previously used for filesystem write refs is now a small library, and used for other heavily used refcounts. Different users of a refcount are enumerated, making it much easier to debug refcount issues. - Async object debugging: There's a new kconfig option that makes various async objects (different types of bios, data updates, write ops, etc.) visible in debugfs, and it should be fast enough to leave on in production. - Various sets of assertions no longer require CONFIG_BCACHEFS_DEBUG, instead they're controlled by module parameters and static keys, meaning users won't need to compile custom kernels as often to help debug issues. - bch2_trans_kmalloc() calls can be tracked (there's a new kconfig option). With it on you can check the btree_transaction_stats in debugfs to see the bch2_trans_kmalloc() calls a transaction did when it used the most memory. * tag 'bcachefs-2025-05-24' of git://evilpiepirate.org/bcachefs: (218 commits) bcachefs: Don't mount bs > ps without TRANSPARENT_HUGEPAGE bcachefs: Fix btree_iter_next_node() for new locking asserts bcachefs: Ensure we don't use a blacklisted journal seq bcachefs: Small check_fix_ptr fixes bcachefs: Fix opts.recovery_pass_last bcachefs: Fix allocate -> self healing path bcachefs: Fix endianness in casefold check/repair bcachefs: Path must be locked if trans->locked && should_be_locked bcachefs: Simplify bch2_path_put() bcachefs: Plumb btree_trans for more locking asserts bcachefs: Clear trans->locked before unlock bcachefs: Clear should_be_locked before unlock in key_cache_drop() bcachefs: bch2_path_get() reuses paths if upgrade_fails & !should_be_locked bcachefs: Give out new path if upgrade fails bcachefs: Fix btree_path_get_locks when not doing trans restart bcachefs: btree_node_locked_type_nowrite() bcachefs: Kill bch2_path_put_nokeep() bcachefs: bch2_journal_write_checksum() bcachefs: Reduce stack usage in data_update_index_update() bcachefs: bch2_trans_log_str() ...	2025-05-26 12:43:30 -07:00

Linus Torvalds	181d8e399f	Merge tag 'vfs-6.16-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs ... Pull misc vfs updates from Christian Brauner: "This contains the usual selections of misc updates for this cycle. Features: - Use folios for symlinks in the page cache FUSE already uses folios for its symlinks. Mirror that conversion in the generic code and the NFS code. That lets us get rid of a few folio->page->folio conversions in this path, and some of the few remaining users of read_cache_page() / read_mapping_page() - Try and make a few filesystem operations killable on the VFS inode->i_mutex level - Add sysctl vfs_cache_pressure_denom for bulk file operations Some workloads need to preserve more dentries than we currently allow through out sysctl interface A HDFS servers with 12 HDDs per server, on a HDFS datanode startup involves scanning all files and caching their metadata (including dentries and inodes) in memory. Each HDD contains approximately 2 million files, resulting in a total of ~20 million cached dentries after initialization To minimize dentry reclamation, they set vfs_cache_pressure to 1. Despite this configuration, memory pressure conditions can still trigger reclamation of up to 50% of cached dentries, reducing the cache from 20 million to approximately 10 million entries. During the subsequent cache rebuild period, any HDFS datanode restart operation incurs substantial latency penalties until full cache recovery completes To maintain service stability, more dentries need to be preserved during memory reclamation. The current minimum reclaim ratio (1/100 of total dentries) remains too aggressive for such workload. This patch introduces vfs_cache_pressure_denom for more granular cache pressure control The configuration [vfs_cache_pressure=1, vfs_cache_pressure_denom=10000] effectively maintains the full 20 million dentry cache under memory pressure, preventing datanode restart performance degradation - Avoid some jumps in inode_permission() using likely()/unlikely() - Avid a memory access which is most likely a cache miss when descending into devcgroup_inode_permission() - Add fastpath predicts for stat() and fdput() - Anonymous inodes currently don't come with a proper mode causing issues in the kernel when we want to add useful VFS debug assert. Fix that by giving them a proper mode and masking it off when we report it to userspace which relies on them not having any mode - Anonymous inodes currently allow to change inode attributes because the VFS falls back to simple_setattr() if i_op->setattr isn't implemented. This means the ownership and mode for every single user of anon_inode_inode can be changed. Block that as it's either useless or actively harmful. If specific ownership is needed the respective subsystem should allocate anonymous inodes from their own private superblock - Raise SB_I_NODEV and SB_I_NOEXEC on the anonymous inode superblock - Add proper tests for anonymous inode behavior - Make it easy to detect proper anonymous inodes and to ensure that we can detect them in codepaths such as readahead() Cleanups: - Port pidfs to the new anon_inode_{g,s}etattr() helpers - Try to remove the uselib() system call - Add unlikely branch hint return path for poll - Add unlikely branch hint on return path for core_sys_select - Don't allow signals to interrupt getdents copying for fuse - Provide a size hint to dir_context for during readdir() - Use writeback_iter directly in mpage_writepages - Update compression and mtime descriptions in initramfs documentation - Update main netfs API document - Remove useless plus one in super_cache_scan() - Remove unnecessary NULL-check guards during setns() - Add separate separate {get,put}_cgroup_ns no-op cases Fixes: - Fix typo in root= kernel parameter description - Use KERN_INFO for infof()|info_plog()|infofc() - Correct comments of fs_validate_description() - Mark an unlikely if condition with unlikely() in vfs_parse_monolithic_sep() - Delete macro fsparam_u32hex() - Remove unused and problematic validate_constant_table() - Fix potential unsigned integer underflow in fs_name() - Make file-nr output the total allocated file handles" * tag 'vfs-6.16-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (43 commits) fs: Pass a folio to page_put_link() nfs: Use a folio in nfs_get_link() fs: Convert __page_get_link() to use a folio fs/read_write: make default_llseek() killable fs/open: make do_truncate() killable fs/open: make chmod_common() and chown_common() killable include/linux/fs.h: add inode_lock_killable() readdir: supply dir_context.count as readdir buffer size hint vfs: Add sysctl vfs_cache_pressure_denom for bulk file operations fuse: don't allow signals to interrupt getdents copying Documentation: fix typo in root= kernel parameter description include/cgroup: separate {get,put}_cgroup_ns no-op case kernel/nsproxy: remove unnecessary guards fs: use writeback_iter directly in mpage_writepages fs: remove useless plus one in super_cache_scan() fs: add S_ANON_INODE fs: remove uselib() system call device_cgroup: avoid access to ->i_rdev in the common case in devcgroup_inode_permission() fs/fs_parse: Remove unused and problematic validate_constant_table() fs: touch up predicts in inode_permission() ...	2025-05-26 09:02:39 -07:00
