git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "This is slightly smaller than usual, with the most interesting work being still around RTNL scope reduction. Core: - More core refactoring to reduce the RTNL lock contention, including preparatory work for the per-network namespace RTNL lock, replacing RTNL lock with a per device-one to protect NAPI-related net device data and moving synchronize_net() calls outside such lock. - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and more specific TCP coverage. - Reduce network namespace tear-down time by removing per-subsystems synchronize_net() in tipc and sched. - Add flow label selector support for fib rules, allowing traffic redirection based on such header field. Netfilter: - Do not remove netdev basechain when last device is gone, allowing netdev basechains without devices. - Revisit the flowtable teardown strategy, dealing better with fin, reset and re-open events. - Scale-up IP-vs connection dumping by avoiding linear search on each restart. Protocols: - A significant XDP socket refactor, consolidating and optimizing several helpers into the core - Better scaling of ICMP rate-limiting, by removing false-sharing in inet peers handling. - Introduces netlink notifications for multicast IPv4 and IPv6 address changes. - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing aggregation and fragmentation of the inner IP. - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to avoid local port exhaustion issues when the average connection lifetime is very short. - Support updating keys (re-keying) for connections using kernel TLS (for TLS 1.3 only). - Support ipv4-mapped ipv6 address clients in smc-r v2. - Add support for jumbo data packet transmission in RxRPC sockets, gluing multiple data packets in a single UDP packet. - Support RxRPC RACK-TLP to manage packet loss and retransmission in conjunction with the congestion control algorithm. Driver API: - Introduce a unified and structured interface for reporting PHY statistics, exposing consistent data across different H/W via ethtool. - Make timestamping selectable, allow the user to select the desired hwtstamp provider (PHY or MAC) administratively. - Add support for configuring a header-data-split threshold (HDS) value via ethtool, to deal with partial or buggy H/W implementation. - Consolidate DSA drivers Energy Efficiency Ethernet support. - Add EEE management to phylink, making use of the phylib implementation. - Add phylib support for in-band capabilities negotiation. - Simplify how phylib-enabled mac drivers expose the supported interfaces. Tests and tooling: - Make the YNL tool package-friendly to make it easier to deploy it separately from the kernel. - Increase TCP selftest coverage importing several packetdrill test-cases. - Regenerate the ethtool uapi header from the YNL spec, to ease maintenance and future development. - Add YNL support for decoding the link types used in net self-tests, allowing a single build to run both net and drivers/net.

2025-01-22Merge tag 'rust-6.14' of ↵Linus Torvalds1-0/+11
git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux Pull rust updates from Miguel Ojeda: "Toolchain and infrastructure: - Finish the move to custom FFI integer types started in the previous cycle and finally map 'long' to 'isize' and 'char' to 'u8'. Do a few cleanups on top thanks to that. - Start to use 'derive(CoercePointee)' on Rust >= 1.84.0. This is a major milestone on the path to build the kernel using only stable Rust features. In particular, previously we were using the unstable features 'coerce_unsized', 'dispatch_from_dyn' and 'unsize', and now we will use the new 'derive_coerce_pointee' one, which is on track to stabilization. This new feature is a macro that essentially expands into code that internally uses the unstable features that we were using before, without having to expose those. With it, stable Rust users, including the kernel, will be able to build custom smart pointers that work with trait objects, e.g.: fn f(p: &Arc<dyn Display>) { pr_info!("{p}\n"); } let a: Arc<dyn Display> = Arc::new(42i32, GFP_KERNEL)?; let b: Arc<dyn Display> = Arc::new("hello there", GFP_KERNEL)?; f(&a); // Prints "42". f(&b); // Prints "hello there". Together with the 'arbitrary_self_types' feature that we started using in the previous cycle, using our custom smart pointers like 'Arc' will eventually only rely in stable Rust. - Introduce 'PROCMACROLDFLAGS' environment variable to allow to link Rust proc macros using different flags than those used for linking Rust host programs (e.g. when 'rustc' uses a different C library than the host programs' one), which Android needs. - Help kernel builds under macOS with Rust enabled by accomodating other naming conventions for dynamic libraries (i.e. '.so' vs. '.dylib') which are used for Rust procedural macros. The actual support for macOS (i.e. the rest of the pieces needed) is provided out-of-tree by others, following the policy used for other parts of the kernel by Kbuild. - Run Clippy for 'rusttest' code too and clean the bits it spotted. - Provide Clippy with the minimum supported Rust version to improve the suggestions it gives. - Document 'bindgen' 0.71.0 regression. 'kernel' crate: - 'build_error!': move users of the hidden function to the documented macro, prevent such uses in the future by moving the function elsewhere and add the macro to the prelude. - 'types' module: add improved version of 'ForeignOwnable::borrow_mut' (which was removed in the past since it was problematic); change 'ForeignOwnable' pointer type to '*mut'. - 'alloc' module: implement 'Display' for 'Box' and align the 'Debug' implementation to it; add example (doctest) for 'ArrayLayout::new()' - 'sync' module: document 'PhantomData' in 'Arc'; use 'NonNull::new_unchecked' in 'ForeignOwnable for Arc' impl. - 'uaccess' module: accept 'Vec's with different allocators in 'UserSliceReader::read_all'. - 'workqueue' module: enable run-testing a couple more doctests. - 'error' module: simplify 'from_errno()'. - 'block' module: fix formatting in code documentation (a lint to catch these is being implemented). - Avoid 'unwrap()'s in doctests, which also improves the examples by showing how kernel code is supposed to be written. - Avoid 'as' casts with 'cast{,_mut}' calls which are a bit safer.

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull kthread updates from Frederic Weisbecker: "Kthreads affinity follow either of 4 existing different patterns: 1) Per-CPU kthreads must stay affine to a single CPU and never execute relevant code on any other CPU. This is currently handled by smpboot code which takes care of CPU-hotplug operations. Affinity here is a correctness constraint. 2) Some kthreads _have_ to be affine to a specific set of CPUs and can't run anywhere else. The affinity is set through kthread_bind_mask() and the subsystem takes care by itself to handle CPU-hotplug operations. Affinity here is assumed to be a correctness constraint. 3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This is not a correctness constraint but merely a preference in terms of memory locality. kswapd and kcompactd both fall into this category. The affinity is set manually like for any other task and CPU-hotplug is supposed to be handled by the relevant subsystem so that the task is properly reaffined whenever a given CPU from the node comes up. Also care should be taken so that the node affinity doesn't cross isolated (nohz_full) cpumask boundaries. 4) Similar to the previous point except kthreads have a _preferred_ affinity different than a node. Both RCU boost kthreads and RCU exp kworkers fall into this category as they refer to "RCU nodes" from a distinctly distributed tree. Currently the preferred affinity patterns (3 and 4) have at least 4 identified users, with more or less success when it comes to handle CPU-hotplug operations and CPU isolation. Each of which do it in its own ad-hoc way. This is an infrastructure proposal to handle this with the following API changes: - kthread_create_on_node() automatically affines the created kthread to its target node unless it has been set as per-cpu or bound with kthread_bind[_mask]() before the first wake-up. - kthread_affine_preferred() is a new function that can be called right after kthread_create_on_node() to specify a preferred affinity different than the specified node. When the preferred affinity can't be applied because the possible targets are offline or isolated (nohz_full), the kthread is affine to the housekeeping CPUs (which means to all online CPUs most of the time or only the non-nohz_full CPUs when nohz_full= is set). kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been converted, along with a few old drivers. Summary of the changes: - Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu() - Introduce task_cpu_fallback_mask() that defines the default last resort affinity of a task to become nohz_full aware - Add some correctness check to ensure kthread_bind() is always called before the first kthread wake up. - Default affine kthread to its preferred node. - Convert kswapd / kcompactd and remove their halfway working ad-hoc affinity implementation - Implement kthreads preferred affinity - Unify kthread worker and kthread API's style - Convert RCU kthreads to the new API and remove the ad-hoc affinity implementation" * tag 'kthread-for-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks: kthread: modify kernel-doc function name to match code rcu: Use kthread preferred affinity for RCU exp kworkers treewide: Introduce kthread_run_worker[_on_cpu]() kthread: Unify kthread_create_on_cpu() and kthread_create_worker_on_cpu() automatic format rcu: Use kthread preferred affinity for RCU boost kthread: Implement preferred affinity mm: Create/affine kswapd to its preferred node mm: Create/affine kcompactd to its preferred node kthread: Default affine kthread to its preferred NUMA node kthread: Make sure kthread hasn't started while binding it sched,arm64: Handle CPU isolation on last resort fallback rq selection arm64: Exclude nohz_full CPUs from 32bits el0 support lib: test_objpool: Use kthread_run_on_cpu() kallsyms: Use kthread_run_on_cpu() soc/qman: test: Use kthread_run_on_cpu() arm/bL_switcher: Use kthread_run_on_cpu()

2025-01-22Documentation: Fix pci=config_acs= exampleAkihiko Odaki1-1/+1
The documentation currently says: config_acs= Format: <ACS flags>@<pci_dev>[; ...] Specify one or more PCI devices (in the format specified above) optionally prepended with flags and separated by semicolons. The respective capabilities will be enabled, disabled or unchanged based on what is specified in flags. (...) For example, pci=config_acs=10x would configure all devices that support ACS to enable P2P Request Redirect, disable Translation Blocking, and leave Source Validation unchanged from whatever power-up or firmware set it to. See the complete documentation at: https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html However, a flag specification always needs to be suffixed with "@" and a PCI valid device address, which is missing in this example. Also, to configure all devices that support ACS, the flag needs to be suffixed with "@pci:0:0", for the ACS support to be enabled. Fix the documentation so the example is correct.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Have fprobes built on top of function graph infrastructure The fprobe logic is an optimized kprobe that uses ftrace to attach to functions when a probe is needed at the start or end of the function. The fprobe and kretprobe logic implements a similar method as the function graph tracer to trace the end of the function. That is to hijack the return address and jump to a trampoline to do the trace when the function exits. To do this, a shadow stack needs to be created to store the original return address. Fprobes and function graph do this slightly differently. Fprobes (and kretprobes) has slots per callsite that are reserved to save the return address. This is fine when just a few points are traced. But users of fprobes, such as BPF programs, are starting to add many more locations, and this method does not scale. The function graph tracer was created to trace all functions in the kernel. In order to do this, when function graph tracing is started, every task gets its own shadow stack to hold the return address that is going to be traced. The function graph tracer has been updated to allow multiple users to use its infrastructure. Now have fprobes be one of those users. This will also allow for the fprobe and kretprobe methods to trace the return address to become obsolete. With new technologies like CFI that need to know about these methods of hijacking the return address, going toward a solution that has only one method of doing this will make the kernel less complex. - Cleanup with guard() and free() helpers There were several places in the code that had a lot of "goto out" in the error paths to either unlock a lock or free some memory that was allocated. But this is error prone. Convert the code over to use the guard() and free() helpers that let the compiler unlock locks or free memory when the function exits. - Remove disabling of interrupts in the function graph tracer When function graph tracer was first introduced, it could race with interrupts and NMIs. To prevent that race, it would disable interrupts and not trace NMIs. But the code has changed to allow NMIs and also interrupts. This change was done a long time ago, but the disabling of interrupts was never removed. Remove the disabling of interrupts in the function graph tracer is it is not needed. This greatly improves its performance. - Allow the :mod: command to enable tracing module functions on the kernel command line. The function tracer already has a way to enable functions to be traced in modules by writing ":mod:<module>" into set_ftrace_filter. That will enable either all the functions for the module if it is loaded, or if it is not, it will cache that command, and when the module is loaded that matches <module>, its functions will be enabled. This also allows init functions to be traced. But currently events do not have that feature. Because enabling function tracing can be done very early at boot up (before scheduling is enabled), the commands that can be done when function tracing is started is limited. Having the ":mod:" command to trace module functions as they are loaded is very useful. Update the kernel command line function filtering to allow it. * tag 'ftrace-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (26 commits) ftrace: Implement :mod: cache filtering on kernel command line tracing: Adopt __free() and guard() for trace_fprobe.c bpf: Use ftrace_get_symaddr() for kprobe_multi probes ftrace: Add ftrace_get_symaddr to convert fentry_ip to symaddr Documentation: probes: Update fprobe on function-graph tracer selftests/ftrace: Add a test case for repeating register/unregister fprobe selftests: ftrace: Remove obsolate maxactive syntax check tracing/fprobe: Remove nr_maxactive from fprobe fprobe: Add fprobe_header encoding feature fprobe: Rewrite fprobe on function-graph tracer s390/tracing: Enable HAVE_FTRACE_GRAPH_FUNC ftrace: Add CONFIG_HAVE_FTRACE_GRAPH_FUNC bpf: Enable kprobe_multi feature if CONFIG_FPROBE is enabled tracing/fprobe: Enable fprobe events with CONFIG_DYNAMIC_FTRACE_WITH_ARGS tracing: Add ftrace_fill_perf_regs() for perf event tracing: Add ftrace_partial_regs() for converting ftrace_regs to pt_regs fprobe: Use ftrace_regs in fprobe exit handler fprobe: Use ftrace_regs in fprobe entry handler fgraph: Pass ftrace_regs to retfunc fgraph: Replace fgraph_ret_regs with ftrace_regs ...

2025-01-21dt-bindings: PCI: qcom,pcie-sm8550: Document 'global' interruptNeil Armstrong1-3/+6
Qcom PCIe RC controllers are capable of generating 'global' SPI interrupt to the host CPU. This interrupt can be used by the device driver to handle PCIe link specific events such as Link up and Link down, which give the driver a chance to start bus enumeration on its own when link is up and initiate link training if link goes to a bad state. The PCIe driver can still work without this interrupt but it will provide a nice user experience when device gets plugged and removed. Document the interrupt as optional for SM8550 and SM8650 platforms.

Pull bcachefs updates from Kent Overstreet: "Lots of scalability work, another big on-disk format change. On-disk format version goes from 1.13 to 1.20. Like 6.11, this is another big and expensive automatic/required on disk format upgrade. This is planned to be the last big on disk format upgrade before the experimental label comes off. There will be one more minor on disk format update for a few things that couldn't make this release. Headline improvements: - Self healing work: Allocator and reflink now run the exact same check/repair code that fsck does at runtime, where applicable. The long term goal here is to remove inconsistent() errors (that cause us to go emergency read only) by lifting fsck code up to normal runtime paths; we should only go emergency read-only if we detect an inconsistency that was due to a runtime bug - or truly catastrophic damage (corrupted btree roots/interior nodes). - Reflink repair no longer deletes reflink pointers: Instead we flip an error bit and log the error, and they can still be deleted by file deletion. This means a temporary failure to find an indirect extent (perhaps repaired later by btree node scan) won't result in unnecessary data loss - Improvements to rebalance data path option handling: We can now correctly apply changed filesystem-level io path options to pending rebalance work, and soon we'll be able to apply file-level io path option changes to indirect extents - Fix mount time regression that some users encountered post the 6.11 disk accounting rewrite. Accounting keys were encoded little endian (typetag in the low bits) - which didn't anticipate adding accounting keys for every inode, which aren't stored in memory and we don't want to scan at mount time. - fsck time on large filesystems is improved by multiple orders of magnitude. Previously, 100TB was about the practical max filesystem size, where users were reporting fsck times of a day+. With the new changes (which nearly eliminate backpointers fsck overhead), we fsck'd a filesystem with 10PB of data in 1.5 hours. The problematic fsck passes were walking every extent and checking for missing backpointers, and walking every backpointer to check for dangling backpointers. As we've been adding more and more runtime self healing there was no reason to keep around the backpointers -> extents pass; dangling backpointers are just deleted, and we can do that when using them - thus, backpointers -> extents is now only run in debug mode. extents -> backpointers does need to exist, since missing backpointers would mean we can't find data to move it (for e.g. copygc, device evacuate, scrub). But the new on disk format version makes possible a new strategy where we sum up backpointers within a bucket and check it against the bucket sector counts, and then only scan for missing backpointers if the counts are off (and then, only for specific buckets). Full list of on disk format changes: - 1.14: backpointer_bucket_gen Backpointers now have a field for the bucket generation number, replacing the obsolete bucket_offset field. This is needed for the new "sum up backpointers within a bucket" code, since backpointers use the btree write buffer - meaning we will see stale reads, and this runs online, with the filesystem in full rw mode. - 1.15: disk_accounting_big_endian As previously described, fix the endianness of accounting keys so that accounting keys with the same typetag sort together, and accounting read can skip types it's not interested in. - 1.16: reflink_p_may_update_opts: This version indicates that a new reflink pointer field is understood and may be used; the field indicates whether the reflink pointer has permissions to update IO path options (e.g. compression, replicas) may be updated on the indirect extent it points to. This completes the rebalance/reflink data path option handling from the 6.13 pull request. - 1.17: inode_depth Add a new inode field, bi_depth, to accelerate the check_directory_structure fsck path, which checks for loops in the filesystem heirarchy. check_inodes and check_dirents check connectivity, so check_directory_structure only has to check for loops - by walking back up to the root from every directory. But a path can't be a loop if it has a counter that increases monotonically from root to leaf - adding a depth counter means that we can check for loops with only local (parent -> child) checks. We might need to occasionally renumber the depth field in fsck if directories have been moved around, but then future fsck runs will be much faster. - 1.18: persistent_inode_cursors Previously, the cursor used for inode allocation was only kept in memory, which meant that users with large filesystems and lots of files were reporting that the first create after mounting would take awhile - since it had to scan from the start. Inode allocation cursors are now persistent, and also include a generation field (incremented on wraparound, which will only happen if inode allocation is restricted to 32 bit inodes), so that we don't have to leave inode_generation keys around after a delete. The option for 32 bit inode numbers may now also be set on individual directories, and non-32 bit inode allocations are disallowed from allocating from the 32 bit part of the inode number space. - 1.19: autofix_errors Runtime self healing is now the default.o - 1.20: directory size (from Hongbo) directory i_size is now meaningful, and not 0" * tag 'bcachefs-2025-01-20.2' of git://evilpiepirate.org/bcachefs: (268 commits) bcachefs: Fix check_inode_hash_info_matches_root() bcachefs: Document issue with bch_stripe layout bcachefs: Fix self healing on read error bcachefs: Pop all the transactions from the abort one bcachefs: Only abort the transactions in the cycle bcachefs: Introduce lock_graph_pop_from bcachefs: Convert open-coded lock_graph_pop_all to helper bcachefs: Do not allow no fail lock request to fail bcachefs: Merge the condition to avoid additional invocation Revert "bcachefs: Fix bch2_btree_node_upgrade()" bcachefs: bcachefs_metadata_version_directory_size bcachefs: make directory i_size meaningful bcachefs: check_unreachable_inodes is not actually PASS_ONLINE yet bcachefs: Don't use BTREE_ITER_cached when walking alloc btree during fsck bcachefs: Check for dirents to overwritten inodes bcachefs: bch2_btree_iter_peek_slot() handles navigating to nonexistent depth bcachefs: Don't set btree_path to updtodate if we don't fill bcachefs: __bch2_btree_pos_to_text() bcachefs: printbuf_reset() handles tabstops bcachefs: Silence read-only errors when deleting snapshots ...

KVM x86 misc changes for 6.14: - Overhaul KVM's CPUID feature infrastructure to track all vCPU capabilities instead of just those where KVM needs to manage state and/or explicitly enable the feature in hardware. Along the way, refactor the code to make it easier to add features, and to make it more self-documenting how KVM is handling each feature. - Rework KVM's handling of VM-Exits during event vectoring; this plugs holes where KVM unintentionally puts the vCPU into infinite loops in some scenarios (e.g. if emulation is triggered by the exit), and brings parity between VMX and SVM. - Add pending request and interrupt injection information to the kvm_exit and kvm_entry tracepoints respectively. - Fix a relatively benign flaw where KVM would end up redoing RDPKRU when loading guest/host PKRU, due to a refactoring of the kernel helpers that didn't account for KVM's pre-checking of the need to do WRPKRU.
