Linus Torvalds	cebcffe666	VFIO updates for v7.0-rc1 ... - Update outdated mdev comment referencing the renamed mdev_type_add() function. (Julia Lawall) - Introduce selftest support for IOMMU mapping of PCI MMIO BARs. (Alex Mastro) - Relax selftest assertion relative to differences in huge page handling between legacy (v1) TYPE1 IOMMU mapping behavior and the compatibility mode supported by IOMMUFD. (David Matlack) - Reintroduce memory poison handling support for non-struct-page- backed memory in the nvgrace-gpu variant driver. (Ankit Agrawal) - Replace dma_buf_phys_vec with phys_vec to avoid duplicate structure and semantics. (Leon Romanovsky) - Add missing upstream bridge locking across PCI function reset, resolving an assertion failure when secondary bus reset is used to provide that reset. (Anthony Pighin) - Fixes to hisi_acc vfio-pci variant driver to resolve corner case issues related to resets, repeated migration, and error injection scenarios. (Longfang Liu, Weili Qian) - Restrict vfio selftest builds to arm64 and x86_64, resolving compiler warnings on 32-bit archs. (Ted Logan) - Un-deprecate the fsl-mc vfio bus driver as a new maintainer has stepped up.

Linus Torvalds	37a93dd5c4	Networking changes for 7.0 ... Core & protocols ---------------- - A significant effort all around the stack to guide the compiler to make the right choice when inlining code, to avoid unneeded calls for small helper and stack canary overhead in the fast-path. This generates better and faster code with very small or no text size increases, as in many cases the call generated more code than the actual inlined helper. - Extend AccECN implementation so that is now functionally complete, also allow the user-space enabling it on a per network namespace basis. - Add support for memory providers with large (above 4K) rx buffer. Paired with hw-gro, larger rx buffer sizes reduce the number of buffers traversing the stack, dincreasing single stream CPU usage by up to ~30%. - Do not add HBH header to Big TCP GSO packets. This simplifies the RX path, the TX path and the NIC drivers, and is possible because user-space taps can now interpret correctly such packets without the HBH hint. - Allow IPv6 routes to be configured with a gateway address that is resolved out of a different interface than the one specified, aligning IPv6 to IPv4 behavior. - Multi-queue aware sch_cake. This makes it possible to scale the rate shaper of sch_cake across multiple CPUs, while still enforcing a single global rate on the interface. - Add support for the nbcon (new buffer console) infrastructure to netconsole, enabling lock-free, priority-based console operations that are safer in crash scenarios. - Improve the TCP ipv6 output path to cache the flow information, saving cpu cycles, reducing cache line misses and stack use. - Improve netfilter packet tracker to resolve clashes for most protocols, avoiding unneeded drops on rare occasions. - Add IP6IP6 tunneling acceleration to the flowtable infrastructure. - Reduce tcp socket size by one cache line. - Notify neighbour changes atomically, avoiding inconsistencies between the notification sequence and the actual states sequence. - Add vsock namespace support, allowing complete isolation of vsocks across different network namespaces. - Improve xsk generic performances with cache-alignment-oriented optimizations. - Support netconsole automatic target recovery, allowing netconsole to reestablish targets when underlying low-level interface comes back online.

This generates better and faster code with very small or no text size increases, as in many cases the call generated more code than the actual inlined helper. - Extend AccECN implementation so that is now functionally complete, also allow the user-space enabling it on a per network namespace basis. - Add support for memory providers with large (above 4K) rx buffer. Paired with hw-gro, larger rx buffer sizes reduce the number of buffers traversing the stack, dincreasing single stream CPU usage by up to ~30%. - Do not add HBH header to Big TCP GSO packets. This simplifies the RX path, the TX path and the NIC drivers, and is possible because user-space taps can now interpret correctly such packets without the HBH hint. - Allow IPv6 routes to be configured with a gateway address that is resolved out of a different interface than the one specified, aligning IPv6 to IPv4 behavior. - Multi-queue aware sch_cake. This makes it possible to scale the rate shaper of sch_cake across multiple CPUs, while still enforcing a single global rate on the interface. - Add support for the nbcon (new buffer console) infrastructure to netconsole, enabling lock-free, priority-based console operations that are safer in crash scenarios. - Improve the TCP ipv6 output path to cache the flow information, saving cpu cycles, reducing cache line misses and stack use. - Improve netfilter packet tracker to resolve clashes for most protocols, avoiding unneeded drops on rare occasions. - Add IP6IP6 tunneling acceleration to the flowtable infrastructure. - Reduce tcp socket size by one cache line. - Notify neighbour changes atomically, avoiding inconsistencies between the notification sequence and the actual states sequence. - Add vsock namespace support, allowing complete isolation of vsocks across different network namespaces. - Improve xsk generic performances with cache-alignment-oriented optimizations. - Support netconsole automatic target recovery, allowing netconsole to reestablish targets when underlying low-level interface comes back online. Driver API: - Support for switching the working mode (automatic vs manual) of a DPLL device via netlink. - Introduce PHY ports representation to expose multiple front-facing media ports over a single MAC. - Introduce "rx-polarity" and "tx-polarity" device tree properties, to generalize polarity inversion requirements for differential signaling. - Add helper to create, prepare and enable managed clocks.

Spotted by syzkaller. 2) Fix esoteric bug in nf_queue with udp fraglist gro, broken since 6.11. Patch 3 adds extends the nfqueue selftest for this. 4) Use dedicated slab for flowtable entries, currently the -512 cache is used, which is wasteful. From Qingfang Deng. 5) Recent net-next update extended existing test for ip6ip6 tunnels, add the required /config entry. Test still passed by accident because the previous tests network setup gets re-used, so also update the test so it will fail in case the ip6ip6 tunnel interface cannot be added. 6) Fix 'nft get element mytable myset { 1.2.3.4 }' on big endian platforms, this was broken since code was added in v5.1. 7) Fix nf_tables counter reset support on 32bit platforms, where counter reset may cause huge values to appear due to wraparound. Broken since reset feature was added in v6.11. From Anders Grahn. 8-11) update nf_tables rbtree set type to detect partial operlaps. This will eventually speed up nftables userspace: at this time userspace does a netlink dump of the set content which slows down incremental updates on interval sets.

Linus Torvalds	36ae1c45b2	Scheduler changes for v7.0: ... Scheduler Kconfig space updates: - Further consolidate configurable preemption modes: reduce the number of architectures that are allowed to offer PREEMPT_NONE and PREEMPT_VOLUNTARY, reducing the number of preemption models from four to just two: 'full' and 'lazy' on up-to-date architectures (arm64, loongarch, powerpc, riscv, s390, x86). None and voluntary are only available as legacy features on platforms that don't implement lazy preemption yet, or which don't even support preemption.

Linus Torvalds	0923fd0419	Locking updates for v6.20: ... Lock debugging: - Implement compiler-driven static analysis locking context checking, using the upcoming Clang 22 compiler's context analysis features. (Marco Elver) We removed Sparse context analysis support, because prior to removal even a defconfig kernel produced 1,700+ context tracking Sparse warnings, the overwhelming majority of which are false positives. On an allmodconfig kernel the number of false positive context tracking Sparse warnings grows to over 5,200... On the plus side of the balance actual locking bugs found by Sparse context analysis is also rather ... sparse: I found only 3 such commits in the last 3 years. So the rate of false positives and the maintenance overhead is rather high and there appears to be no active policy in place to achieve a zero-warnings baseline to move the annotations & fixers to developers who introduce new code. Clang context analysis is more complete and more aggressive in trying to find bugs, at least in principle. Plus it has a different model to enabling it: it's enabled subsystem by subsystem, which results in zero warnings on all relevant kernel builds (as far as our testing managed to cover it). Which allowed us to enable it by default, similar to other compiler warnings, with the expectation that there are no warnings going forward. This enforces a zero-warnings baseline on clang-22+ builds. (Which are still limited in distribution, admittedly.) Hopefully the Clang approach can lead to a more maintainable zero-warnings status quo and policy, with more and more subsystems and drivers enabling the feature. Context tracking can be enabled for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y (default disabled), but this will generate a lot of false positives. ( Having said that, Sparse support could still be added back, if anyone is interested - the removal patch is still relatively straightforward to revert at this stage. ) Rust integration updates: (Alice Ryhl, Fujita Tomonori, Boqun Feng) - Add support for Atomic<i8/i16/bool> and replace most Rust native AtomicBool usages with Atomic<bool> - Clean up LockClassKey and improve its documentation - Add missing Send and Sync trait implementation for SetOnce - Make ARef Unpin as it is supposed to be - Add __rust_helper to a few Rust helpers as a preparation for helper LTO - Inline various lock related functions to avoid additional function calls.

Felix Maurer	8908c3c8ce	selftests: hsr: Add tests for more link faults with PRP ... Add tests where one link has different rates of packet loss or reorders packets. PRP should still be able to recover from these link faults and show no packet loss. However, it is acceptable to receive some level of duplicate packets. This matches the current specification (IEC 62439-3:2021) of the duplicate discard algorithm that requires it to be "designed such that it never rejects a legitimate frame, while occasional acceptance of a duplicate can be tolerated." The rate of acceptable duplicates in this test is intentionally high (10%) to make the test stable, the values I observed in the worst test cases (20% loss) are around 5% duplicates. The duplicates occur because of the 10ms ping interval in the test. As blocks expire after 400ms based on the timestamp of the first received sequence number in the block, every approx. 40th will lead to a new, clean block being used where the sequence number hasn't been seen before. As this occurs on both nodes in the test (for requests and replies), we observe around 20 duplicate frames.

Felix Maurer	ca4a09a950	selftests: hsr: Add tests for faulty links ... Add a test case that can support different types of faulty links for all protocol versions (HSRv0, HSRv1, PRPv1). It starts with a baseline with fully functional links. The first faulty case is one link being cut during the ping. This test uses a different function for ping that sends more packets in shorter intervals to stress the duplicate detection algorithms a bit more and allow for future tests with other link faults (packet loss, reordering, etc.). As the link fault tests now cover the cut link for HSR and PRP, it can be removed from the hsr_ping test. Note that the removed cut link test did not really test the fault because do_ping_long takes about 1sec while the link is only cut after a 3sec sleep.

Felix Maurer	776b64ba12	selftests: hsr: Check duplicates on HSR with VLAN ... Previously the hsr_ping test only checked that all nodes in a VLAN are reachable (using do_ping). Update the test to also check that there is no packet loss and no duplicate packets by running the same tests for VLANs as without VLANs (including using do_ping_long). This also adds tests for IPv6 over VLAN. To unify the test code, the topology without VLANs now uses IP addresses from dead:beef:0::/64 to align with the 100.64.0.0/24 range for IPv4. Error messages are updated across the board to make it easier to find what actually failed. Also update the VLAN test to only run in VLAN 2, as there is no need to check if ping really works with VLAN IDs 2, 3, 4, and 5. This lowers the number of long ping tests on VLANs to keep the overall test runtime in bounds. It's still necessary to bump the test timeout a bit, though: a ping long tests takes 1sec, do_ping_tests performs 12 of them, do_link_problem_tests 6, and the VLAN tests again 12. With some buffer for setup and waiting and for two protocol versions, 90sec timeout seems reasonable.

For detached mounts the STATMOUNT_MNT_POINT and STATMOUNT_MNT_NS_ID mask bits are cleared since neither is meaningful.

Documentation references to the legacy callbacks are cleaned up. - mount: add OPEN_TREE_NAMESPACE to open_tree() Container runtimes currently use CLONE_NEWNS to copy the caller's entire mount namespace — only to then pivot_root() and recursively unmount everything they just copied. With large mount tables and thousands of parallel container launches this creates significant contention on the namespace semaphore. OPEN_TREE_NAMESPACE copies only the specified mount tree (like OPEN_TREE_CLONE) but returns a mount namespace fd instead of a detached mount fd. The new namespace contains the copied tree mounted on top of a clone of the real rootfs. This functions as a combined unshare(CLONE_NEWNS) + pivot_root() in a single syscall. Works with user namespaces: an unshare(CLONE_NEWUSER) followed by OPEN_TREE_NAMESPACE creates a mount namespace owned by the new user namespace. Mount namespace file mounts are excluded from the copy to prevent cycles.

RCU Tasks Trace: Re-implement RCU tasks trace in term of SRCU-fast, not only more than 500 lines of code are saved because of the reimplementation, a new set of API, rcu_read_{,un}lock_tasks_trace(), becomes possible as well. Compared to the previous rcu_read_{,un}lock_trace(), the new API avoid the task_struct accesses thanks to the SRCU-fast semantics. As a result, the old rcu_read{,un}lock_trace() API is now deprecated. RCU Torture Test: - Multiple improvements on kvm-series.sh (parallel run and progress showing metrics) - Add context checks to rcu_torture_timer(). - Make config2csv.sh properly handle comments in .boot files. - Include commit discription in testid.txt. Miscellaneous RCU changes: - Reduce synchronize_rcu() latency by reporting GP kthread's CPU QS early. - Use suitable gfp_flags for the init_srcu_struct_nodes(). - Fix rcu_read_unlock() deadloop due to softirq. - Correctly compute probability to invoke ->exp_current() in rcutorture. - Make expedited RCU CPU stall warnings detect stall-end races.

Larysa Zaremba	88af9fefed	selftests/xsk: fix number of Tx frags in invalid packet ... The issue occurs in TOO_MANY_FRAGS test case when xdp_zc_max_segs is set to an odd number. TOO_MANY_FRAGS test case contains an invalid packet consisting of (xdp_zc_max_segs) frags. Every frag, even the last one has XDP_PKT_CONTD flag set. This packet is expected to be dropped. After that, there is a valid linear packet, which is expected to be received back. Once (xdp_zc_max_segs) is an odd number, the last packet cannot be received, if packet forwarding between Rx and Tx interfaces relies on the ethernet header, e.g. checks for ETH_P_LOOPBACK. Packet is malformed, if all traffic is looped. Turns out, sending function processes multiple invalid frags as if they were in 2-frag packets. So once the invalid mbuf packet contains an odd number of those, the valid packet after gets paired with the previous invalid descriptor, and hence does not get an ethernet header generated, so it is either dropped or malformed. Make invalid packets in verbatim mode always have only a single frag. For such packets, number of frags is otherwise meaningless, as descriptor flags are pre-configured in verbatim mode and packet data is not generated for invalid descriptors.

Günther Noack	42fc7e6543	landlock: Multithreading support for landlock_restrict_self() ... Introduce the LANDLOCK_RESTRICT_SELF_TSYNC flag. With this flag, a given Landlock ruleset is applied to all threads of the calling process, instead of only the current one. Without this flag, multithreaded userspace programs currently resort to using the nptl(7)/libpsx hack for multithreaded policy enforcement, which is also used by libcap and for setuid(2). Using this userspace-based scheme, the threads of a process enforce the same Landlock policy, but the resulting Landlock domains are still separate. The domains being separate causes multiple problems: * When using Landlock's "scoped" access rights, the domain identity is used to determine whether an operation is permitted. As a result, when using LANLDOCK_SCOPE_SIGNAL, signaling between sibling threads stops working. This is a problem for programming languages and frameworks which are inherently multithreaded (e.g. Go). * In audit logging, the domains of separate threads in a process will get logged with different domain IDs, even when they are based on the same ruleset FD, which might confuse users.

This should have caught by CI, but as the config option is missing, the tunnel interface isn't added. This results in an error cascade that ends with "route change default" failure. That in turn means the "ipv6 tunnel" test re-uses the previous test setup so the "ip6ip6" test passes and script returns 0. Make sure to catch such bugs, set ret=1 if device cannot be added and delete the old default route before installing the new one. After this change, IPV6_TUNNEL=n kernel builds fail with the expected FAIL: flow offload for ns1/ns2 with IP6IP6 tunnel ... while builds with IPV6_TUNNEL=m pass as before.
