The following data-race was found in show_numa_info(): ================================================================== BUG: KCSAN: data-race in vmalloc_info_show / vmalloc_info_show read to 0xffff88800971fe30 of 4 bytes by task 8289 on cpu 0: show_numa_info mm/vmalloc.c:4936 [inline] vmalloc_info_show+0x5a8/0x7e0 mm/vmalloc.c:5016 seq_read_iter+0x373/0xb40 fs/seq_file.c:230 proc_reg_read_iter+0x11e/0x170 fs/proc/inode.c:299 .... write to 0xffff88800971fe30 of 4 bytes by task 8287 on cpu 1: show_numa_info mm/vmalloc.c:4934 [inline] vmalloc_info_show+0x38f/0x7e0 mm/vmalloc.c:5016 seq_read_iter+0x373/0xb40 fs/seq_file.c:230 proc_reg_read_iter+0x11e/0x170 fs/proc/inode.c:299 .... value changed: 0x0000008f -> 0x00000000 ================================================================== According to this report,there is a read/write data-race because m->private is accessible to multiple CPUs. To fix this, instead of allocating the heap in proc_vmalloc_init() and passing the heap address to m->private, vmalloc_info_show() should allocate the heap.

Pre-existing allocations are already counted against the request through mas_node_count_gfp(), but the allocations will not happen if the MA_STATE_PREALLOC flag is set. This flag is meant to avoid re-allocating in bulk allocation mode, and to detect issues with preallocation calculations. The MA_STATE_PREALLOC flag should also always be set on zero allocations so that detection of underflow allocations will print a WARN_ON() during consumption. User visible effect of this flaw is a WARN_ON() followed by a null pointer dereference when subsequent requests for larger number of nodes is ignored, such as the vma merge retry in mmap_region() caused by drivers altering the vma flags (which happens in v6.6, at least) Link: https://lkml.kernel.org/r/20250616184521.3382795-3-Liam.Howlett@oracle.com Fixes: 54a611b60590 ("Maple Tree: add new data structure") Signed-off-by: Liam R.

[PATCH 5.15.y v3] xen: replace xen_remap() with memremap()

by Teddy Astie

From: Juergen Gross <jgross(a)suse.com> [ upstream commit 41925b105e345ebc84cedb64f59d20cb14a62613 ] xen_remap() is used to establish mappings for frames not under direct control of the kernel: for Xenstore and console ring pages, and for grant pages of non-PV guests. Today xen_remap() is defined to use ioremap() on x86 (doing uncached mappings), and ioremap_cache() on Arm (doing cached mappings). Uncached mappings for those use cases are bad for performance, so they should be avoided if possible. As all use cases of xen_remap() don't require uncached mappings (the mapped area is always physical RAM), a mapping using the standard WB cache mode is fine. As sparse is flagging some of the xen_remap() use cases to be not appropriate for iomem(), as the result is not annotated with the __iomem modifier, eliminate xen_remap() completely and replace all use cases with memremap() specifying the MEMREMAP_WB caching mode. xen_unmap() can be replaced with memunmap().

[PATCH 5.15] ice: safer stats processing

by Przemek Kitszel

From: Jesse Brandeburg <jesse.brandeburg(a)intel.com> [ Upstream commit 1a0f25a52e08b1f67510cabbb44888d2b3c46359 ] Fix an issue of stats growing indefinitely, minor conflict resolved: struct ice_tx_ring replaced by struct ice_ring, as the split is not yet present on 5.15 line. -Przemek Original commit message: The driver was zeroing live stats that could be fetched by ndo_get_stats64 at any time. This could result in inconsistent statistics, and the telltale sign was when reading stats frequently from /proc/net/dev, the stats would go backwards. Fix by collecting stats into a local, and delaying when we write to the structure so it's not incremental.

[PATCH v4] riscv: hwprobe: Fix stale vDSO data for late-initialized keys at boot

by Jingwei Wang

The value for some hwprobe keys, like MISALIGNED_VECTOR_PERF, is determined by an asynchronous kthread. This kthread can finish after the hwprobe vDSO data is populated, creating a race condition where userspace can read stale values. A completion-based framework is introduced to synchronize the async probes with the vDSO population. The init_hwprobe_vdso_data() function is deferred to `late_initcall` and now blocks until all probes signal completion. Reported-by: Tsukasa OI <research_trasio(a)irq.a4lg.com> Closes: https://lore.kernel.org/linux-riscv/760d637b-b13b-4518-b6bf-883d55d44e7f@ir… Fixes: e7c9d66e313b ("RISC-V: Report vector unaligned access speed hwprobe") Cc: Palmer Dabbelt <palmer(a)dabbelt.com> Cc: Alexandre Ghiti <alexghiti(a)rivosinc.com> Cc: stable(a)vger.kernel.org Signed-off-by: Jingwei Wang <wangjingwei(a)iscas.ac.cn> --- Changes in v4: - Reworked the synchronization mechanism based on feedback from Palmer and Alexandre. - Instead of a post-hoc refresh, this version introduces a robust completion-based framework using an atomic counter to ensure async probes are finished before populating the vDSO. - Moved the vdso data initialization to a late_initcall to avoid impacting boot time. Changes in v3: - Retained existing blank line. Changes in v2: - Addressed feedback from Yixun's regarding #ifdef CONFIG_MMU usage. - Updated commit message to provide a high-level summary. - Added Fixes tag for commit e7c9d66e313b. v1: https://lore.kernel.org/linux-riscv/20250521052754.185231-1-wangjingwei@isc… arch/riscv/include/asm/hwprobe.h | 8 +++++++- arch/riscv/kernel/sys_hwprobe.c | 20 +++++++++++++++++++- arch/riscv/kernel/unaligned_access_speed.c | 9 +++++++-- 3 files changed, 33 insertions(+), 4 deletions(-) diff --git a/arch/riscv/include/asm/hwprobe.h b/arch/riscv/include/asm/hwprobe.h index 7fe0a379474ae2c6..87af186d92e75ddb 100644 --- a/arch/riscv/include/asm/hwprobe.h +++ b/arch/riscv/include/asm/hwprobe.h @@ -40,5 +40,11 @@ static inline bool riscv_hwprobe_pair_cmp(struct riscv_hwprobe *pair, return pair->value == other_pair->value; } - +#ifdef CONFIG_MMU +void riscv_hwprobe_register_async_probe(void); +void riscv_hwprobe_complete_async_probe(void); +#else +inline void riscv_hwprobe_register_async_probe(void) {} +inline void riscv_hwprobe_complete_async_probe(void) {} +#endif #endif diff --git a/arch/riscv/kernel/sys_hwprobe.c b/arch/riscv/kernel/sys_hwprobe.c index 0b170e18a2beba57..8c50dcec2b754c30 100644 --- a/arch/riscv/kernel/sys_hwprobe.c +++ b/arch/riscv/kernel/sys_hwprobe.c @@ -5,6 +5,8 @@ * more details. */ #include <linux/syscalls.h> +#include <linux/completion.h> +#include <linux/atomic.h> #include <asm/cacheflush.h> #include <asm/cpufeature.h> #include <asm/hwprobe.h> @@ -467,6 +469,20 @@ static int do_riscv_hwprobe(struct riscv_hwprobe __user *pairs, #ifdef CONFIG_MMU +static DECLARE_COMPLETION(boot_probes_done); +static atomic_t pending_boot_probes = ATOMIC_INIT(0); + +void riscv_hwprobe_register_async_probe(void) +{ + atomic_inc(&pending_boot_probes); +} + +void riscv_hwprobe_complete_async_probe(void) +{ + if (atomic_dec_and_test(&pending_boot_probes)) + complete(&boot_probes_done); +} + static int __init init_hwprobe_vdso_data(void) { struct vdso_arch_data *avd = vdso_k_arch_data; @@ -474,6 +490,8 @@ static int __init init_hwprobe_vdso_data(void) struct riscv_hwprobe pair; int key; + if (unlikely(atomic_read(&pending_boot_probes) > 0)) + wait_for_completion(&boot_probes_done); /* * Initialize vDSO data with the answers for the "all CPUs" case, to * save a syscall in the common case. @@ -504,7 +522,7 @@ static int __init init_hwprobe_vdso_data(void) return 0; } -arch_initcall_sync(init_hwprobe_vdso_data); +late_initcall(init_hwprobe_vdso_data); #endif /* CONFIG_MMU */ diff --git a/arch/riscv/kernel/unaligned_access_speed.c b/arch/riscv/kernel/unaligned_access_speed.c index ae2068425fbcd207..4b8ad2673b0f7470 100644 --- a/arch/riscv/kernel/unaligned_access_speed.c +++ b/arch/riscv/kernel/unaligned_access_speed.c @@ -379,6 +379,7 @@ static void check_vector_unaligned_access(struct work_struct *work __always_unus static int __init vec_check_unaligned_access_speed_all_cpus(void *unused __always_unused) { schedule_on_each_cpu(check_vector_unaligned_access); + riscv_hwprobe_complete_async_probe(); return 0; } @@ -473,8 +474,12 @@ static int __init check_unaligned_access_all_cpus(void) per_cpu(vector_misaligned_access, cpu) = unaligned_vector_speed_param; } else if (!check_vector_unaligned_access_emulated_all_cpus() && IS_ENABLED(CONFIG_RISCV_PROBE_VECTOR_UNALIGNED_ACCESS)) { - kthread_run(vec_check_unaligned_access_speed_all_cpus, - NULL, "vec_check_unaligned_access_speed_all_cpus"); + riscv_hwprobe_register_async_probe(); + if (IS_ERR(kthread_run(vec_check_unaligned_access_speed_all_cpus, + NULL, "vec_check_unaligned_access_speed_all_cpus"))) { + pr_warn("Failed to create vec_unalign_check kthread\n"); + riscv_hwprobe_complete_async_probe(); + } } /* -- 2.50.0

[PATCH 0/3] Various devicetree fixes for Exynos7870 devices

by Kaustabh Chakraborty

This patch series introduces a few minor fixes on Exynos7870 devices. These fix USB gadget problems and serious crashes on certain variants of devices. More information is provided in respective commits. This series has no dependencies. Would be nice to get them merged in 6.16 itself. I assume it's okay to cc stable as the -rc releases are also owned by the "Stable Group" in git.kernel.org...
