Re: [PATCH 00/13] netfs, cifs: Fixes to retry-related code

Hi David, your commit 2b1424cd131c ("netfs: Fix wait/wake to be consistent about the waitqueue used") has given me serious headaches; it has caused outages in our web hosting clusters (yet again - all Linux versions since 6.9 had serious netfs regressions). Your patch was backported to 6.15 as commit 329ba1cb402a in 6.15.3 (why oh why??), and therefore the bugs it has caused will be "available" to all Linux stable users. The problem we had is that writing to certain files never finishes. It looks like it has to do with the cachefiles subrequest never reporting completion. (We use Ceph with cachefiles) I have tried applying the fixes in this pull request, which sounded promising, but the problem is still there. The only thing that helps is reverting 2b1424cd131c completely - everything is fine with 6.15.5 plus the revert. What do you need from me in order to analyze the bug? Max

[PATCH 6.12.y] drm/amdgpu: Replace Mutex with Spinlock for RLCG register access to avoid Priority Inversion in SRIOV

by jetlan9＠163.com

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> [ Upstream commit dc0297f3198bd60108ccbd167ee5d9fa4af31ed0 ] RLCG Register Access is a way for virtual functions to safely access GPU registers in a virtualized environment., including TLB flushes and register reads. When multiple threads or VFs try to access the same registers simultaneously, it can lead to race conditions. By using the RLCG interface, the driver can serialize access to the registers. This means that only one thread can access the registers at a time, preventing conflicts and ensuring that operations are performed correctly. Additionally, when a low-priority task holds a mutex that a high-priority task needs, ie., If a thread holding a spinlock tries to acquire a mutex, it can lead to priority inversion. register access in amdgpu_virt_rlcg_reg_rw especially in a fast code path is critical. The call stack shows that the function amdgpu_virt_rlcg_reg_rw is being called, which attempts to acquire the mutex. This function is invoked from amdgpu_sriov_wreg, which in turn is called from gmc_v11_0_flush_gpu_tlb. The [ BUG: Invalid wait context ] indicates that a thread is trying to acquire a mutex while it is in a context that does not allow it to sleep (like holding a spinlock). Fixes the below: [ 253.013423] ============================= [ 253.013434] [ BUG: Invalid wait context ] [ 253.013446] 6.12.0-amdstaging-drm-next-lol-050225 #14 Tainted: G U OE [ 253.013464] ----------------------------- [ 253.013475] kworker/0:1/10 is trying to lock: [ 253.013487] ffff9f30542e3cf8 (&adev->virt.rlcg_reg_lock){+.+.}-{3:3}, at: amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu] [ 253.013815] other info that might help us debug this: [ 253.013827] context-{4:4} [ 253.013835] 3 locks held by kworker/0:1/10: [ 253.013847] #0: ffff9f3040050f58 ((wq_completion)events){+.+.}-{0:0}, at: process_one_work+0x3f5/0x680 [ 253.013877] #1: ffffb789c008be40 ((work_completion)(&wfc.work)){+.+.}-{0:0}, at: process_one_work+0x1d6/0x680 [ 253.013905] #2: ffff9f3054281838 (&adev->gmc.invalidate_lock){+.+.}-{2:2}, at: gmc_v11_0_flush_gpu_tlb+0x198/0x4f0 [amdgpu] [ 253.014154] stack backtrace: [ 253.014164] CPU: 0 UID: 0 PID: 10 Comm: kworker/0:1 Tainted: G U OE 6.12.0-amdstaging-drm-next-lol-050225 #14 [ 253.014189] Tainted: [U]=USER, [O]=OOT_MODULE, [E]=UNSIGNED_MODULE [ 253.014203] Hardware name: Microsoft Corporation Virtual Machine/Virtual Machine, BIOS Hyper-V UEFI Release v4.1 11/18/2024 [ 253.014224] Workqueue: events work_for_cpu_fn [ 253.014241] Call Trace: [ 253.014250] <TASK> [ 253.014260] dump_stack_lvl+0x9b/0xf0 [ 253.014275] dump_stack+0x10/0x20 [ 253.014287] __lock_acquire+0xa47/0x2810 [ 253.014303] ? srso_alias_return_thunk+0x5/0xfbef5 [ 253.014321] lock_acquire+0xd1/0x300 [ 253.014333] ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu] [ 253.014562] ? __lock_acquire+0xa6b/0x2810 [ 253.014578] __mutex_lock+0x85/0xe20 [ 253.014591] ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu] [ 253.014782] ? sched_clock_noinstr+0x9/0x10 [ 253.014795] ? srso_alias_return_thunk+0x5/0xfbef5 [ 253.014808] ? local_clock_noinstr+0xe/0xc0 [ 253.014822] ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu] [ 253.015012] ? srso_alias_return_thunk+0x5/0xfbef5 [ 253.015029] mutex_lock_nested+0x1b/0x30 [ 253.015044] ? mutex_lock_nested+0x1b/0x30 [ 253.015057] amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu] [ 253.015249] amdgpu_sriov_wreg+0xc5/0xd0 [amdgpu] [ 253.015435] gmc_v11_0_flush_gpu_tlb+0x44b/0x4f0 [amdgpu] [ 253.015667] gfx_v11_0_hw_init+0x499/0x29c0 [amdgpu] [ 253.015901] ? __pfx_smu_v13_0_update_pcie_parameters+0x10/0x10 [amdgpu] [ 253.016159] ? srso_alias_return_thunk+0x5/0xfbef5 [ 253.016173] ? smu_hw_init+0x18d/0x300 [amdgpu] [ 253.016403] amdgpu_device_init+0x29ad/0x36a0 [amdgpu] [ 253.016614] amdgpu_driver_load_kms+0x1a/0xc0 [amdgpu] [ 253.017057] amdgpu_pci_probe+0x1c2/0x660 [amdgpu] [ 253.017493] local_pci_probe+0x4b/0xb0 [ 253.017746] work_for_cpu_fn+0x1a/0x30 [ 253.017995] process_one_work+0x21e/0x680 [ 253.018248] worker_thread+0x190/0x330 [ 253.018500] ? __pfx_worker_thread+0x10/0x10 [ 253.018746] kthread+0xe7/0x120 [ 253.018988] ? __pfx_kthread+0x10/0x10 [ 253.019231] ret_from_fork+0x3c/0x60 [ 253.019468] ? __pfx_kthread+0x10/0x10 [ 253.019701] ret_from_fork_asm+0x1a/0x30 [ 253.019939] </TASK> v2: s/spin_trylock/spin_lock_irqsave to be safe (Christian).

[PATCH v4 1/8] drm/panfrost: Fix scheduler workqueue bug

by Philipp Stanner

When the GPU scheduler was ported to using a struct for its initialization parameters, it was overlooked that panfrost creates a distinct workqueue for timeout handling. The pointer to this new workqueue is not initialized to the struct, resulting in NULL being passed to the scheduler, which then uses the system_wq for timeout handling. Set the correct workqueue to the init args struct.

[PATCH 2/2] mmc: core: sd: Fix and simplify SD card current limit handling

by Avri Altman

The SD spec says: "In UHS-I mode, after selecting one of SDR50, SDR104, or DDR50 mode by Function Group 1, host needs to change the Power Limit to enable the card to operate in higher performance". The driver previously determined SD card current limits incorrectly by checking capability bits before bus speed was established, and by using support bits in function group 4 (bytes 6 & 7) rather than the actual current requirement (bytes 0 & 1). This is wrong because the card responds for a given bus speed. This patch queries the card's current requirement after setting the bus speed, and uses the reported value to select the appropriate current limit. while at it, remove some unused constants and the misleading comment in the code.

Its filename was ocfs2-reset-folio-to-null-when-get-folio-fails.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Lizhi Xu <lizhi.xu(a)windriver.com> Subject: ocfs2: reset folio to NULL when get folio fails Date: Mon, 16 Jun 2025 09:31:40 +0800 The reproducer uses FAULT_INJECTION to make memory allocation fail, which causes __filemap_get_folio() to fail, when initializing w_folios[i] in ocfs2_grab_folios_for_write(), it only returns an error code and the value of w_folios[i] is the error code, which causes ocfs2_unlock_and_free_folios() to recycle the invalid w_folios[i] when releasing folios.

[merged mm-stable] mm-ptdump-take-the-memory-hotplug-lock-inside-ptdump_walk_pgd.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/ptdump: take the memory hotplug lock inside ptdump_walk_pgd() has been removed from the -mm tree. Its filename was mm-ptdump-take-the-memory-hotplug-lock-inside-ptdump_walk_pgd.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Anshuman Khandual <anshuman.khandual(a)arm.com> Subject: mm/ptdump: take the memory hotplug lock inside ptdump_walk_pgd() Date: Fri, 20 Jun 2025 10:54:27 +0530 Memory hot remove unmaps and tears down various kernel page table regions as required. The ptdump code can race with concurrent modifications of the kernel page tables. When leaf entries are modified concurrently, the dump code may log stale or inconsistent information for a VA range, but this is otherwise not harmful. But when intermediate levels of kernel page table are freed, the dump code will continue to use memory that has been freed and potentially reallocated for another purpose. In such cases, the ptdump code may dereference bogus addresses, leading to a number of potential problems. To avoid the above mentioned race condition, platforms such as arm64, riscv and s390 take memory hotplug lock, while dumping kernel page table via the sysfs interface /sys/kernel/debug/kernel_page_tables. Similar race condition exists while checking for pages that might have been marked W+X via /sys/kernel/debug/kernel_page_tables/check_wx_pages which in turn calls ptdump_check_wx(). Instead of solving this race condition again, let's just move the memory hotplug lock inside generic ptdump_check_wx() which will benefit both the scenarios. Drop get_online_mems() and put_online_mems() combination from all existing platform ptdump code paths.

[merged mm-stable] mm-huge_memory-dont-ignore-queried-cachemode-in-vmf_insert_pfn_pud.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/huge_memory: don't ignore queried cachemode in vmf_insert_pfn_pud() has been removed from the -mm tree. Its filename was mm-huge_memory-dont-ignore-queried-cachemode-in-vmf_insert_pfn_pud.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/huge_memory: don't ignore queried cachemode in vmf_insert_pfn_pud() Date: Fri, 13 Jun 2025 11:27:00 +0200 Patch series "mm/huge_memory: vmf_insert_folio_*() and vmf_insert_pfn_pud() fixes", v3. While working on improving vm_normal_page() and friends, I stumbled over this issues: refcounted "normal" folios must not be marked using pmd_special() / pud_special(). Otherwise, we're effectively telling the system that these folios are no "normal", violating the rules we documented for vm_normal_page(). Fortunately, there are not many pmd_special()/pud_special() users yet. So far there doesn't seem to be serious damage. Tested using the ndctl tests ("ndctl:dax" suite). This patch (of 3): We set up the cache mode but ... don't forward the updated pgprot to insert_pfn_pud(). Only a problem on x86-64 PAT when mapping PFNs using PUDs that require a special cachemode. Fix it by using the proper pgprot where the cachemode was setup. It is unclear in which configurations we would get the cachemode wrong: through vfio seems possible. Getting cachemodes wrong is usually ... bad. As the fix is easy, let's backport it to stable. Identified by code inspection.

[merged mm-stable] mm-memory-tier-fix-abstract-distance-calculation-overflow.patch removed from -mm tree

The quilt patch titled Subject: mm/memory-tier: fix abstract distance calculation overflow has been removed from the -mm tree. Its filename was mm-memory-tier-fix-abstract-distance-calculation-overflow.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Li Zhijian <lizhijian(a)fujitsu.com> Subject: mm/memory-tier: fix abstract distance calculation overflow Date: Tue, 10 Jun 2025 14:27:51 +0800 In mt_perf_to_adistance(), the calculation of abstract distance (adist) involves multiplying several int values including MEMTIER_ADISTANCE_DRAM. *adist = MEMTIER_ADISTANCE_DRAM * (perf->read_latency + perf->write_latency) / (default_dram_perf.read_latency + default_dram_perf.write_latency) * (default_dram_perf.read_bandwidth + default_dram_perf.write_bandwidth) / (perf->read_bandwidth + perf->write_bandwidth); Since these values can be large, the multiplication may exceed the maximum value of an int (INT_MAX) and overflow (Our platform did), leading to an incorrect adist. User-visible impact: The memory tiering subsystem will misinterpret slow memory (like CXL) as faster than DRAM, causing inappropriate demotion of pages from CXL (slow memory) to DRAM (fast memory). For example, we will see the following demotion chains from the dmesg, where Node0,1 are DRAM, and Node2,3 are CXL node: Demotion targets for Node 0: null Demotion targets for Node 1: null Demotion targets for Node 2: preferred: 0-1, fallback: 0-1 Demotion targets for Node 3: preferred: 0-1, fallback: 0-1 Change MEMTIER_ADISTANCE_DRAM to be a long constant by writing it with the 'L' suffix. This prevents the overflow because the multiplication will then be done in the long type which has a larger range.

VMware Workstation Pro w/ recent Kernel-6.15.4

by Christopher Turcotte

Good morning I'm hoping for a resolution to an issue I'm currently having with the latest kernel release and Workstation Pro (Free Edition). Every time I try to open Workstation, it's prompting me to reinstall modules that ultimately fail (see screenshots). Also see the attached log file. After doing some research, I see the issue is that several header files are missing. I've tried to manually compile and install original modules, but with no success. I'm still faced with an incompatibility issue and the latest kernel. This problem does not occur when I switch back to kernel 6.14. I'm currently running the latest kernel (6.15.4) on Fedora 42. My hardware specs: CPU: AMD Ryzen 7840U Memory: Crucial 96 GB 5600 DDR5 [Screenshot From 2025-07-08 16-53-52.png][Screenshot From 2025-07-08 16-54-06.png],

[merged mm-hotfixes-stable] mm-fix-the-inaccurate-memory-statistics-issue-for-users.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm: fix the inaccurate memory statistics issue for users has been removed from the -mm tree. Its filename was mm-fix-the-inaccurate-memory-statistics-issue-for-users.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Baolin Wang <baolin.wang(a)linux.alibaba.com> Subject: mm: fix the inaccurate memory statistics issue for users Date: Thu, 5 Jun 2025 20:58:29 +0800 On some large machines with a high number of CPUs running a 64K pagesize kernel, we found that the 'RES' field is always 0 displayed by the top command for some processes, which will cause a lot of confusion for users. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 875525 root 20 0 12480 0 0 R 0.3 0.0 0:00.08 top 1 root 20 0 172800 0 0 S 0.0 0.0 0:04.52 systemd The main reason is that the batch size of the percpu counter is quite large on these machines, caching a significant percpu value, since converting mm's rss stats into percpu_counter by commit f1a7941243c1 ("mm: convert mm's rss stats into percpu_counter"). Intuitively, the batch number should be optimized, but on some paths, performance may take precedence over statistical accuracy. Therefore, introducing a new interface to add the percpu statistical count and display it to users, which can remove the confusion. In addition, this change is not expected to be on a performance-critical path, so the modification should be acceptable. In addition, the 'mm->rss_stat' is updated by using add_mm_counter() and dec/inc_mm_counter(), which are all wrappers around percpu_counter_add_batch(). In percpu_counter_add_batch(), there is percpu batch caching to avoid 'fbc->lock' contention. This patch changes task_mem() and task_statm() to get the accurate mm counters under the 'fbc->lock', but this should not exacerbate kernel 'mm->rss_stat' lock contention due to the percpu batch caching of the mm counters. The following test also confirm the theoretical analysis. I run the stress-ng that stresses anon page faults in 32 threads on my 32 cores machine, while simultaneously running a script that starts 32 threads to busy-loop pread each stress-ng thread's /proc/pid/status interface. From the following data, I did not observe any obvious impact of this patch on the stress-ng tests. w/o patch: stress-ng: info: [6848] 4,399,219,085,152 CPU Cycles 67.327 B/sec stress-ng: info: [6848] 1,616,524,844,832 Instructions 24.740 B/sec (0.367 instr. per cycle) stress-ng: info: [6848] 39,529,792 Page Faults Total 0.605 M/sec stress-ng: info: [6848] 39,529,792 Page Faults Minor 0.605 M/sec w/patch: stress-ng: info: [2485] 4,462,440,381,856 CPU Cycles 68.382 B/sec stress-ng: info: [2485] 1,615,101,503,296 Instructions 24.750 B/sec (0.362 instr. per cycle) stress-ng: info: [2485] 39,439,232 Page Faults Total 0.604 M/sec stress-ng: info: [2485] 39,439,232 Page Faults Minor 0.604 M/sec On comparing a very simple app which just allocates & touches some memory against v6.1 (which doesn't have f1a7941243c1) and latest Linus tree (4c06e63b9203) I can see that on latest Linus tree the values for VmRSS, RssAnon and RssFile from /proc/self/status are all zeroes while they do report values on v6.1 and a Linus tree with this patch.

Its filename was mm-damon-core-handle-damon_call_control-as-normal-under-kdmond-deactivation.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/core: handle damon_call_control as normal under kdmond deactivation Date: Sun, 29 Jun 2025 13:49:14 -0700 DAMON sysfs interface internally uses damon_call() to update DAMON parameters as users requested, online. However, DAMON core cancels any damon_call() requests when it is deactivated by DAMOS watermarks. As a result, users cannot change DAMON parameters online while DAMON is deactivated. Note that users can turn DAMON off and on with different watermarks to work around. Since deactivated DAMON is nearly same to stopped DAMON, the work around should have no big problem. Anyway, a bug is a bug. There is no real good reason to cancel the damon_call() request under DAMOS deactivation. Fix it by simply handling the request as normal, rather than cancelling under the situation.

[merged mm-hotfixes-stable] mm-rmap-fix-potential-out-of-bounds-page-table-access-during-batched-unmap.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/rmap: fix potential out-of-bounds page table access during batched unmap has been removed from the -mm tree. Its filename was mm-rmap-fix-potential-out-of-bounds-page-table-access-during-batched-unmap.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Lance Yang <lance.yang(a)linux.dev> Subject: mm/rmap: fix potential out-of-bounds page table access during batched unmap Date: Fri, 27 Jun 2025 14:23:19 +0800 As pointed out by David[1], the batched unmap logic in try_to_unmap_one() may read past the end of a PTE table when a large folio's PTE mappings are not fully contained within a single page table. While this scenario might be rare, an issue triggerable from userspace must be fixed regardless of its likelihood. This patch fixes the out-of-bounds access by refactoring the logic into a new helper, folio_unmap_pte_batch(). The new helper correctly calculates the safe batch size by capping the scan at both the VMA and PMD boundaries. To simplify the code, it also supports partial batching (i.e., any number of pages from 1 up to the calculated safe maximum), as there is no strong reason to special-case for fully mapped folios.

Its filename was scripts-gdb-fix-interruptspy-after-maple-tree-conversion.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Florian Fainelli <florian.fainelli(a)broadcom.com> Subject: scripts/gdb: fix interrupts.py after maple tree conversion Date: Tue, 24 Jun 2025 19:10:20 -0700 In commit 721255b9826b ("genirq: Use a maple tree for interrupt descriptor management"), the irq_desc_tree was replaced with a sparse_irqs tree using a maple tree structure. Since the script looked for the irq_desc_tree symbol which is no longer available, no interrupts would be printed and the script output would not be useful anymore. In addition to looking up the correct symbol (sparse_irqs), a new module (mapletree.py) is added whose mtree_load() implementation is largely copied after the C version and uses the same variable and intermediate function names wherever possible to ensure that both the C and Python version be updated in the future. This restores the scripts' output to match that of /proc/interrupts.

The reason is mt_destroy_walk() leverage mte_destroy_descend() to set node dead, but this is skipped since the only root node is a leaf. Fixes this by setting the node dead if it is a leaf.

Before the commit, the issue occurred only when it failed to allocate and initialize alloc_tag_cttype or if a memory allocation fails before alloc_tag_init() is called. After the commit, it can be easily triggered when memory profiling is compiled but disabled at boot. To properly determine whether alloc_tag_init() has been called and its data structures initialized, verify that alloc_tag_cttype is a valid pointer before acquiring the semaphore. If the variable is NULL or an error value, it has not been properly initialized. In such a case, just skip and do not attempt to acquire the semaphore.

The current mTHP swapin path have several problems. It may potentially hang, may cause redundant faults due to false positive swap cache lookup, and it will involve at least 4 Xarray tree walks (get order, get order again, confirm swap, insert folio). And for !CONFIG_TRANSPARENT_HUGEPAGE builds, it will performs some mTHP related checks. This series fixes all of the mentioned issues, and the code should be more robust and prepared for the swap table series. Now tree walks is reduced to twice (get order & confirm, insert folio), !CONFIG_TRANSPARENT_HUGEPAGE build overhead is also minimized, and comes with a sanity check now. The performance is slightly better after this series, sequential swap in of 24G data from ZRAM, using transparent_hugepage_tmpfs=always (24 samples each): Before: Avg: 10.67s, stddev: 0.04 After patch 1: Avg: 10.49s, stddev: 0.04 After patch 2: Avg: 10.42s, stddev: 0.05 After patch 3: Avg: 10.45s, stddev: 0.05 After patch 4: Avg: 10.49s, stddev: 0.04 After patch 5: Avg: 9.67s, stddev: 0.03 After patch 6: Avg: 9.67s, stddev: 0.04 After patch 7: Avg: 9.68s, stddev: 0.05 After patch 8: Avg: 9.66s, stddev: 0.04 Several patches improve the performance by a little, which is about ~10% faster in total. Build kernel test showed very slightly improvement, testing with make -j48 with defconfig in a 768M memcg also using ZRAM as swap, and transparent_hugepage_tmpfs=always (6 test runs): Before: avg: 3353.66s, stddev: 33.73 After patch 1: avg: 3354.19s, stddev: 42.54 After patch 2: avg: 3364.16s, stddev: 52.74 After patch 3: avg: 3355.73s, stddev: 36.17 After patch 4: avg: 3352.78s, stddev: 39.80 After patch 5: avg: 3355.19s, stddev: 50.78 After patch 6: avg: 3333.63s, stddev: 32.50 After patch 7: avg: 3297.70s, stddev: 38.93 After patch 8: avg: 3302.35s, stddev: 50.61 This patch (of 8): The current swap-in code assumes that, when a swap entry in shmem mapping is order 0, its cached folios (if present) must be order 0 too, which turns out not always correct. The problem is shmem_split_large_entry is called before verifying the folio will eventually be swapped in, one possible race is: CPU1 CPU2 shmem_swapin_folio /* swap in of order > 0 swap entry S1 */ folio = swap_cache_get_folio /* folio = NULL */ order = xa_get_order /* order > 0 */ folio = shmem_swap_alloc_folio /* mTHP alloc failure, folio = NULL */ <... Interrupted ...> shmem_swapin_folio /* S1 is swapped in */ shmem_writeout /* S1 is swapped out, folio cached */ shmem_split_large_entry(..., S1) /* S1 is split, but the folio covering it has order > 0 now */ Now any following swapin of S1 will hang: `xa_get_order` returns 0, and folio lookup will return a folio with order > 0. The `xa_get_order(&mapping->i_pages, index) != folio_order(folio)` will always return false causing swap-in to return -EEXIST. And this looks fragile. So fix this up by allowing seeing a larger folio in swap cache, and check the whole shmem mapping range covered by the swapin have the right swap value upon inserting the folio. And drop the redundant tree walks before the insertion. This will actually improve performance, as it avoids two redundant Xarray tree walks in the hot path, and the only side effect is that in the failure path, shmem may redundantly reallocate a few folios causing temporary slight memory pressure. And worth noting, it may seems the order and value check before inserting might help reducing the lock contention, which is not true. The swap cache layer ensures raced swapin will either see a swap cache folio or failed to do a swapin (we have SWAP_HAS_CACHE bit even if swap cache is bypassed), so holding the folio lock and checking the folio flag is already good enough for avoiding the lock contention. The chance that a folio passes the swap entry value check but the shmem mapping slot has changed should be very low.

[PATCH v2] zynq_fpga: use sgtable-based scatterlist wrappers

Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of statterlists related calls. dma_unmap_sg() function has to be called with the number of elements originally passed to the dma_map_sg() function, not the one returned in sgtable's nents.

[PATCH 1/1] Drivers: hv: Select CONFIG_SYSFB only if EFI is enabled

by mhkelley58＠gmail.com

From: Michael Kelley <mhklinux(a)outlook.com> Commit 96959283a58d ("Drivers: hv: Always select CONFIG_SYSFB for Hyper-V guests") selects CONFIG_SYSFB for Hyper-V guests so that screen_info is available to the VMBus driver to get the location of the framebuffer in Generation 2 VMs. However, if CONFIG_HYPERV is enabled but CONFIG_EFI is not, a kernel link error results in ARM64 builds because screen_info is provided by the EFI firmware interface. While configuring an ARM64 Hyper-V guest without EFI isn't useful since EFI is required to boot, the configuration is still possible and the link error should be prevented. Fix this by making the selection of CONFIG_SYSFB conditional on CONFIG_EFI being defined. For Generation 1 VMs on x86/x64, which don't use EFI, the additional condition is OK because such VMs get the framebuffer information via a mechanism that doesn't use screen_info.

[PATCH AUTOSEL 6.15 1/8] Revert "ACPI: battery: negate current when discharging"

by Sasha Levin

From: "Rafael J. Wysocki" <rafael.j.wysocki(a)intel.com> [ Upstream commit de1675de39aa945bad5937d1fde4df3682670639 ] Revert commit 234f71555019 ("ACPI: battery: negate current when discharging") breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud. Perhaps it breaks more, but those are the two that have been tested. Reported-by: Matthew Schwartz <matthew.schwartz(a)linux.dev> Closes: https://lore.kernel.org/linux-acpi/87C1B2AF-D430-4568-B620-14B941A8ABA4@lin… Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES**, this commit should be backported to stable kernel trees. ## Extensive Explanation: ### 1. **Critical Userspace Regression Fix** This revert fixes a critical regression that breaks userspace applications. The commit message explicitly states that the original change "breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud." This is a clear violation of the kernel's "no userspace regressions" rule, which is one of the most fundamental principles in kernel development. ### 2. **Code Analysis Shows ABI Change** Looking at the code changes: ```c // The problematic code that was added (and is now being removed): if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && acpi_battery_handle_discharging(battery) == POWER_SUPPLY_STATUS_DISCHARGING) val->intval = -val->intval; ``` This code was changing the sign of the current value when discharging, which altered the userspace-visible ABI. Even if the original behavior didn't match documentation, changing it broke existing applications that depended on the long-standing behavior. ### 3. **Simple and Safe Revert** The commit is a clean revert that: - Removes the problematic sign negation logic - Restores the original behavior that userspace applications expect - Is self-contained to the `acpi_battery_get_property()` function - Has minimal risk of introducing new issues ### 4. **Meets Stable Kernel Criteria** According to stable kernel rules, this commit qualifies because it: - **Fixes a real bug** that users are hitting (broken battery monitoring in Steam and MangoHud) - **Is obviously correct** (it's a revert of a change that broke userspace) - **Is small and contained** (only affects the ACPI battery property reporting) - **Has been tested** (the reporter confirmed the issue) - **Fixes a regression** (restores previous working behavior) ### 5. **Comparison to Similar Commits** Looking at the historical commits marked with "Backport Status: YES", they share similar characteristics: - Fix actual problems affecting users - Are relatively small and contained changes - Don't introduce new features or architectural changes - Focus on fixing specific issues This revert fits perfectly into this pattern as it's fixing a specific userspace compatibility issue without introducing any new functionality. ### 6. **Timing Considerations** The original problematic commit (234f71555019) was from May 8, 2025, and this revert is from July 3, 2025. If the original commit made it into any stable releases, those stable trees would need this revert to prevent userspace breakage. ### Conclusion: This is a textbook example of a commit that should be backported to stable kernels. It fixes a userspace regression, is minimal in scope, carries very low risk, and restores previously working behavior that applications depend on. The fact that it's a revert of a problematic change makes it even more suitable for stable backporting. drivers/acpi/battery.c | 19 +++---------------- 1 file changed, 3 insertions(+), 16 deletions(-) diff --git a/drivers/acpi/battery.c b/drivers/acpi/battery.c index 93bb1f7d90986..6760330a8af55 100644 --- a/drivers/acpi/battery.c +++ b/drivers/acpi/battery.c @@ -243,23 +243,10 @@ static int acpi_battery_get_property(struct power_supply *psy, break; case POWER_SUPPLY_PROP_CURRENT_NOW: case POWER_SUPPLY_PROP_POWER_NOW: - if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) { + if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) ret = -ENODEV; - break; - } - - val->intval = battery->rate_now * 1000; - /* - * When discharging, the current should be reported as a - * negative number as per the power supply class interface - * definition. - */ - if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && - (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && - acpi_battery_handle_discharging(battery) - == POWER_SUPPLY_STATUS_DISCHARGING) - val->intval = -val->intval; - + else + val->intval = battery->rate_now * 1000; break; case POWER_SUPPLY_PROP_CHARGE_FULL_DESIGN: case POWER_SUPPLY_PROP_ENERGY_FULL_DESIGN: -- 2.39.5

[tip: x86/urgent] x86/mm: Disable hugetlb page table sharing on 32-bit

by tip-bot2 for Jann Horn

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 76303ee8d54bff6d9a6d55997acd88a6c2ba63cf Gitweb: https://git.kernel.org/tip/76303ee8d54bff6d9a6d55997acd88a6c2ba63cf Author: Jann Horn <jannh(a)google.com> AuthorDate: Wed, 02 Jul 2025 10:32:04 +02:00 Committer: Dave Hansen <dave.hansen(a)linux.intel.com> CommitterDate: Wed, 09 Jul 2025 07:46:36 -07:00 x86/mm: Disable hugetlb page table sharing on 32-bit Only select ARCH_WANT_HUGE_PMD_SHARE on 64-bit x86. Page table sharing requires at least three levels because it involves shared references to PMD tables; 32-bit x86 has either two-level paging (without PAE) or three-level paging (with PAE), but even with three-level paging, having a dedicated PGD entry for hugetlb is only barely possible (because the PGD only has four entries), and it seems unlikely anyone's actually using PMD sharing on 32-bit. Having ARCH_WANT_HUGE_PMD_SHARE enabled on non-PAE 32-bit X86 (which has 2-level paging) became particularly problematic after commit 59d9094df3d7 ("mm: hugetlb: independent PMD page table shared count"), since that changes `struct ptdesc` such that the `pt_mm` (for PGDs) and the `pt_share_count` (for PMDs) share the same union storage - and with 2-level paging, PMDs are PGDs. (For comparison, arm64 also gates ARCH_WANT_HUGE_PMD_SHARE on the configuration of page tables such that it is never enabled with 2-level paging.)

[PATCH 0/3] HID: core: fix __hid_request when no report ID is used

by Benjamin Tissoires

[Ideally I'd like to have tests in selftests, but I couldn't extract them out of the syzbot reproducer, so sending that first series to check against syzbot] Followup of https://lore.kernel.org/linux-input/c75433e0-9b47-4072-bbe8-b1d14ea97b13@ro… This initial series attempt at fixing the various bugs discovered by Alan regarding __hid_request(). Syzbot managed to create a report descriptor which presents a feature request of size 0 (still trying to extract it) and this exposed the fact that __hid_request() was incorrectly handling the case when the report ID is not used. Send a first batch of fixes now so we get the feedback from syzbot ASAP. Note: in the series, I also mentioned that the report of size 0 should be stripped out of the HID device, but without a local reproducer this is going to be difficult to implement.

[PATCH 1/2] drm/gem: Fix race in drm_gem_handle_create_tail()

by Simona Vetter

Object creation is a careful dance where we must guarantee that the object is fully constructed before it is visible to other threads, and GEM buffer objects are no difference. Final publishing happens by calling drm_gem_handle_create(). After that the only allowed thing to do is call drm_gem_object_put() because a concurrent call to the GEM_CLOSE ioctl with a correctly guessed id (which is trivial since we have a linear allocator) can already tear down the object again. Luckily most drivers get this right, the very few exceptions I've pinged the relevant maintainers for. Unfortunately we also need drm_gem_handle_create() when creating additional handles for an already existing object (e.g. GETFB ioctl or the various bo import ioctl), and hence we cannot have a drm_gem_handle_create_and_put() as the only exported function to stop these issues from happening. Now unfortunately the implementation of drm_gem_handle_create() isn't living up to standards: It does correctly finishe object initialization at the global level, and hence is safe against a concurrent tear down. But it also sets up the file-private aspects of the handle, and that part goes wrong: We fully register the object in the drm_file.object_idr before calling drm_vma_node_allow() or obj->funcs->open, which opens up races against concurrent removal of that handle in drm_gem_handle_delete(). Fix this with the usual two-stage approach of first reserving the handle id, and then only registering the object after we've completed the file-private setup. Jacek reported this with a testcase of concurrently calling GEM_CLOSE on a freshly-created object (which also destroys the object), but it should be possible to hit this with just additional handles created through import or GETFB without completed destroying the underlying object with the concurrent GEM_CLOSE ioctl calls. Note that the close-side of this race was fixed in f6cd7daecff5 ("drm: Release driver references to handle before making it available again"), which means a cool 9 years have passed until someone noticed that we need to make this symmetry or there's still gaps left :-/ Without the 2-stage close approach we'd still have a race, therefore that's an integral part of this bugfix. More importantly, this means we can have NULL pointers behind allocated id in our drm_file.object_idr. We need to check for that now: - drm_gem_handle_delete() checks for ERR_OR_NULL already - drm_gem.c:object_lookup() also chekcs for NULL - drm_gem_release() should never be called if there's another thread still existing that could call into an IOCTL that creates a new handle, so cannot race. For paranoia I added a NULL check to drm_gem_object_release_handle() though. - most drivers (etnaviv, i915, msm) are find because they use idr_find(), which maps both ENOENT and NULL to NULL. - drivers using idr_for_each_entry() should also be fine, because idr_get_next does filter out NULL entries and continues the iteration. - The same holds for drm_show_memory_stats(). v2: Use drm_WARN_ON (Thomas) Reported-by: Jacek Lawrynowicz <jacek.lawrynowicz(a)linux.intel.com> Tested-by: Jacek Lawrynowicz <jacek.lawrynowicz(a)linux.intel.com> Reviewed-by: Thomas Zimmermann <tzimmermann(a)suse.de> Cc: stable(a)vger.kernel.org Cc: Jacek Lawrynowicz <jacek.lawrynowicz(a)linux.intel.com> Cc: Maarten Lankhorst <maarten.lankhorst(a)linux.intel.com> Cc: Maxime Ripard <mripard(a)kernel.org> Cc: Thomas Zimmermann <tzimmermann(a)suse.de> Cc: David Airlie <airlied(a)gmail.com> Cc: Simona Vetter <simona(a)ffwll.ch> Signed-off-by: Simona Vetter <simona.vetter(a)intel.com> Signed-off-by: Simona Vetter <simona.vetter(a)ffwll.ch> --- drivers/gpu/drm/drm_gem.c | 10 +++++++++- include/drm/drm_file.h | 3 +++ 2 files changed, 12 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/drm_gem.c b/drivers/gpu/drm/drm_gem.c index bc505d938b3e..1aa9192c4cc6 100644 --- a/drivers/gpu/drm/drm_gem.c +++ b/drivers/gpu/drm/drm_gem.c @@ -316,6 +316,9 @@ drm_gem_object_release_handle(int id, void *ptr, void *data) struct drm_file *file_priv = data; struct drm_gem_object *obj = ptr; + if (drm_WARN_ON(obj->dev, !data)) + return 0; + if (obj->funcs->close) obj->funcs->close(obj, file_priv); @@ -436,7 +439,7 @@ drm_gem_handle_create_tail(struct drm_file *file_priv, idr_preload(GFP_KERNEL); spin_lock(&file_priv->table_lock); - ret = idr_alloc(&file_priv->object_idr, obj, 1, 0, GFP_NOWAIT); + ret = idr_alloc(&file_priv->object_idr, NULL, 1, 0, GFP_NOWAIT); spin_unlock(&file_priv->table_lock); idr_preload_end(); @@ -457,6 +460,11 @@ drm_gem_handle_create_tail(struct drm_file *file_priv, goto err_revoke; } + /* mirrors drm_gem_handle_delete to avoid races */ + spin_lock(&file_priv->table_lock); + obj = idr_replace(&file_priv->object_idr, obj, handle); + WARN_ON(obj != NULL); + spin_unlock(&file_priv->table_lock); *handlep = handle; return 0; diff --git a/include/drm/drm_file.h b/include/drm/drm_file.h index eab7546aad79..115763799625 100644 --- a/include/drm/drm_file.h +++ b/include/drm/drm_file.h @@ -300,6 +300,9 @@ struct drm_file { * * Mapping of mm object handles to object pointers.

Backport perf makefile fix to linux-6.6.y

by Alexis Lothoré

Hello stable team, could you please backport commit 440cf77625e3 ("perf: build: Setup PKG_CONFIG_LIBDIR for cross compilation") to linux-6.6.y ? Its absence prevents some people from building the perf tool in cross-compile environment with this kernel. The patch applies cleanly on linux-6.6.y Thanks, Alexis -- Alexis Lothoré, Bootlin Embedded Linux and Kernel engineering https://bootlin.com

[RFC V1 PATCH mm-hotfixes 3/3] x86/mm: convert {pgd,p4d}_populate{,_init} to _kernel variant

by Harry Yoo

Introduce {pgd,p4d}_populate_kernel_safe() and convert {pgd,p4d}_populate{,_init}() to {pgd,p4d}_populate_kernel{,_init}(). By converting them, we no longer need to worry about forgetting to synchronize top level page tables. With all {pgd,p4d}_populate{,_init}() converted to {pgd,p4d}_populate_kernel{,_init}(), it is now safe to drop sync_global_pgds(). Let's remove it.

v6.16-rc5: ttys: auto login failed Login incorrect

by Naresh Kamboju

Approximately 20% of devices are experiencing intermittent boot failures with this kernel version. The issue appears to be related to auto login failures, where an incorrect password is being detected on the serial console during the login process. This intermittent regression is noticed on stable-rc 6.15.5-rc2 and Linux mainline master v6.16-rc5. This regressions is only specific to the devices not on the qemu's. Test environments: - dragonboard-410c - dragonboard-845c - e850-96 - juno-r2 - rk3399-rock-pi-4b - x86 Regression Analysis: - New regression? Yes - Reproducibility? 20% only Test regression: 6.15.5-rc2 v6.16-rc5 auto login failed Login incorrect Reported-by: Linux Kernel Functional Testing <lkft(a)linaro.org> ## log in problem runner-ns46nmmj-project-40964107-concurrent-0 login: # Password: Login incorrect runner-ns46nmmj-project-40964107-concurrent-0 login: ## Investigation The following three patches were reverted and the system was re-tested.

page_pool_put_full_page() should only be invoked when freeing Rx buffers or building a skb if the size is too short. At other times, the pages need to be reused. So remove the redundant page put.

[PATCH net 3/3] net: libwx: properly reset Rx ring descriptor

by Jiawen Wu

When device reset is triggered by feature changes such as toggling Rx VLAN offload, wx->do_reset() is called to reinitialize Rx rings. The hardware descriptor ring may retain stale values from previous sessions. And only set the length to 0 in rx_desc[0] would result in building malformed SKBs. Fix it to ensure a clean slate after device reset. [ 549.186435] [ C16] ------------[ cut here ]------------ [ 549.186457] [ C16] kernel BUG at net/core/skbuff.c:2814!

[PATCH net 2/3] net: libwx: fix the using of Rx buffer DMA

by Jiawen Wu

The wx_rx_buffer structure contained two DMA address fields: 'dma' and 'page_dma'. However, only 'page_dma' was actually initialized and used to program the Rx descriptor. But 'dma' was uninitialized and used in some paths. This could lead to undefined behavior, including DMA errors or use-after-free, if the uninitialized 'dma' was used. Althrough such error has not yet occurred, it is worth fixing in the code.

[BACKPORT][PATCH 6.12.y 1/2] firmware: arm_ffa: Move memory allocation outside the mutex locking

by Sudeep Holla

[ Upstream commit 27e850c88df0e25474a8caeb2903e2e90b62c1dc ] The notifier callback node allocation is currently done while holding the notify_lock mutex. While this is safe even if memory allocation may sleep, we need to move the allocation outside the locked region in preparation to move from using muxtes to rwlocks. Move the memory allocation to avoid potential sleeping in atomic context once the locks are moved from mutex to rwlocks.

[PATCH 6.12,6.15] crypto: s390/sha - Fix uninitialized variable in SHA-1 and SHA-2

by Eric Biggers

commit 68279380266a5fa70e664de754503338e2ec3f43 upstream. Commit 88c02b3f79a6 ("s390/sha3: Support sha3 performance enhancements") added the field s390_sha_ctx::first_message_part and made it be used by s390_sha_update() (now s390_sha_update_blocks()). At the time, s390_sha_update() was used by all the s390 SHA-1, SHA-2, and SHA-3 algorithms. However, only the initialization functions for SHA-3 were updated, leaving SHA-1 and SHA-2 using first_message_part uninitialized. This could cause e.g. the function code CPACF_KIMD_SHA_512 | CPACF_KIMD_NIP to be used instead of just CPACF_KIMD_SHA_512. This apparently was harmless, as the SHA-1 and SHA-2 function codes ignore CPACF_KIMD_NIP; it is recognized only by the SHA-3 function codes (https://lore.kernel.org/r/73477fe9-a1dc-4e38-98a6-eba9921e8afa@linux.ibm.co…). Therefore, this bug was found only when first_message_part was later converted to a boolean and UBSAN detected its uninitialized use. Regardless, let's fix this by just initializing to zero. Note: in 6.16, we need to patch SHA-1, SHA-384, and SHA-512. In 6.15 and earlier, we'll also need to patch SHA-224 and SHA-256, as they hadn't yet been librarified (which incidentally fixed this bug).

[PATCH] arm64: dts: ti: k3-j722s-evm: Fix USB gpio-hog level for Type-C

by Siddharth Vadapalli

According to the "GPIO Expander Map / Table" section of the J722S EVM Schematic within the Evaluation Module Design Files package [0], the GPIO Pin P05 located on the GPIO Expander 1 (I2C0/0x23) has to be pulled down to select the Type-C interface. Since commit under Fixes claims to enable the Type-C interface, update the property within "p05-hog" from "output-high" to "output-low", thereby switching from the Type-A interface to the Type-C interface.

[PATCH] drm/panfrost: Fix scheduler workqueue bug

by Philipp Stanner

When the GPU scheduler was ported to using a struct for its initialization parameters, it was overlooked that panfrost creates a distinct workqueue for timeout handling.

[PATCH wireless v1] wifi: mwifiex: discard erroneous disassoc frames on STA interface

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> When operating in concurrent STA/AP mode with host MLME enabled, the firmware incorrectly sends disassociation frames to the STA interface when clients disconnect from the AP interface. This causes kernel warnings as the STA interface processes disconnect events that don't apply to it: [ 1303.240540] WARNING: CPU: 0 PID: 513 at net/wireless/mlme.c:141 cfg80211_process_disassoc+0x78/0xec [cfg80211] [ 1303.250861] Modules linked in: 8021q garp stp mrp llc rfcomm bnep btnxpuart nls_iso8859_1 nls_cp437 onboard_us [ 1303.327651] CPU: 0 UID: 0 PID: 513 Comm: kworker/u9:2 Not tainted 6.16.0-rc1+ #3 PREEMPT [ 1303.335937] Hardware name: Toradex Verdin AM62 WB on Verdin Development Board (DT) [ 1303.343588] Workqueue: MWIFIEX_RX_WORK_QUEUE mwifiex_rx_work_queue [mwifiex] [ 1303.350856] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 1303.357904] pc : cfg80211_process_disassoc+0x78/0xec [cfg80211] [ 1303.364065] lr : cfg80211_process_disassoc+0x70/0xec [cfg80211] [ 1303.370221] sp : ffff800083053be0 [ 1303.373590] x29: ffff800083053be0 x28: 0000000000000000 x27: 0000000000000000 [ 1303.380855] x26: 0000000000000000 x25: 00000000ffffffff x24: ffff000002c5b8ae [ 1303.388120] x23: ffff000002c5b884 x22: 0000000000000001 x21: 0000000000000008 [ 1303.395382] x20: ffff000002c5b8ae x19: ffff0000064dd408 x18: 0000000000000006 [ 1303.402646] x17: 3a36333a61623a30 x16: 32206d6f72662063 x15: ffff800080bfe048 [ 1303.409910] x14: ffff000003625300 x13: 0000000000000001 x12: 0000000000000000 [ 1303.417173] x11: 0000000000000002 x10: ffff000003958600 x9 : ffff000003625300 [ 1303.424434] x8 : ffff00003fd9ef40 x7 : ffff0000039fc280 x6 : 0000000000000002 [ 1303.431695] x5 : ffff0000038976d4 x4 : 0000000000000000 x3 : 0000000000003186 [ 1303.438956] x2 : 000000004836ba20 x1 : 0000000000006986 x0 : 00000000d00479de [ 1303.446221] Call trace: [ 1303.448722] cfg80211_process_disassoc+0x78/0xec [cfg80211] (P) [ 1303.454894] cfg80211_rx_mlme_mgmt+0x64/0xf8 [cfg80211] [ 1303.460362] mwifiex_process_mgmt_packet+0x1ec/0x460 [mwifiex] [ 1303.466380] mwifiex_process_sta_rx_packet+0x1bc/0x2a0 [mwifiex] [ 1303.472573] mwifiex_handle_rx_packet+0xb4/0x13c [mwifiex] [ 1303.478243] mwifiex_rx_work_queue+0x158/0x198 [mwifiex] [ 1303.483734] process_one_work+0x14c/0x28c [ 1303.487845] worker_thread+0x2cc/0x3d4 [ 1303.491680] kthread+0x12c/0x208 [ 1303.495014] ret_from_fork+0x10/0x20 Add validation in the STA receive path to verify that disassoc/deauth frames originate from the connected AP. Frames that fail this check are discarded early, preventing them from reaching the MLME layer and triggering WARN_ON(). This filtering logic is similar with that used in the ieee80211_rx_mgmt_disassoc() function in mac80211, which drops disassoc frames that don't match the current BSSID (!ether_addr_equal(mgmt->bssid, sdata->vif.cfg.ap_addr)), ensuring only relevant frames are processed.

[PATCH 1/2] mmc: core sd: Simplify current limit logic for 200mA default

by Avri Altman

The SD current limit logic is updated to avoid explicitly setting the current limit when the maximum power is 200mA (0.72W) or less, as this is already the default value. The code now only issues a current limit switch if a higher limit is required, and the unused SD_SET_CURRENT_NO_CHANGE constant is removed. This reduces unnecessary commands and simplifies the logic.

[PATCH v4 1/2] PCI: imx6: Remove apps_reset toggle in _core_reset functions

by Richard Zhu

apps_reset is LTSSM_EN on i.MX7, i.MX8MQ, i.MX8MM and i.MX8MP platforms. Since the assertion/de-assertion of apps_reset(LTSSM_EN bit) had been wrappered in imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable(); Remove apps_reset toggle in imx_pcie_assert_core_reset() and imx_pcie_deassert_core_reset() functions. Use imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable() to configure apps_reset directly. Fix fail to enumerate reliably PI7C9X2G608GP (hotplug) at i.MX8MM, which reported By Tim. Only i.MX7D, i.MX8MQ, i.MX8MM, and i.MX8MP have the apps_reset. With this change, the assertion/deassertion of LTSSM_EN bit are unified into imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable() functions, and aligned with other i.MX platforms.

If another kind of race is triggered (folio changed after lookup) we may see RSS counter is corrupted: [ 406.893936] BUG: Bad rss-counter state mm:ffff0000c5a9ddc0 type:MM_ANONPAGES val:-1 [ 406.894071] BUG: Bad rss-counter state mm:ffff0000c5a9ddc0 type:MM_SHMEMPAGES val:1 Because the folio is being accounted to the wrong VMA. I'm not sure if there will be any data corruption though, seems no. The issues above are critical already. On seeing a swap entry PTE, userfaultfd_move does a lockless swap cache lookup, and tries to move the found folio to the faulting vma. Currently, it relies on checking the PTE value to ensure that the moved folio still belongs to the src swap entry and that no new folio has been added to the swap cache, which turns out to be unreliable. While working and reviewing the swap table series with Barry, following existing races are observed and reproduced [1]: In the example below, move_pages_pte is moving src_pte to dst_pte, where src_pte is a swap entry PTE holding swap entry S1, and S1 is not in the swap cache: CPU1 CPU2 userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1 ... < interrupted> ... <swapin src_pte, alloc and use folio A> // folio A is a new allocated folio // and get installed into src_pte <frees swap entry S1> // src_pte now points to folio A, S1 // has swap count == 0, it can be freed // by folio_swap_swap or swap // allocator's reclaim. <try to swap out another folio B> // folio B is a folio in another VMA. <put folio B to swap cache using S1 > // S1 is freed, folio B can use it // for swap out with no problem. ... folio = filemap_get_folio(S1) // Got folio B here !!! ... < interrupted again> ... <swapin folio B and free S1> // Now S1 is free to be used again. <swapout src_pte & folio A using S1> // Now src_pte is a swap entry PTE // holding S1 again. folio_trylock(folio) move_swap_pte double_pt_lock is_pte_pages_stable // Check passed because src_pte == S1 folio_move_anon_rmap(...) // Moved invalid folio B here !!! The race window is very short and requires multiple collisions of multiple rare events, so it's very unlikely to happen, but with a deliberately constructed reproducer and increased time window, it can be reproduced easily. This can be fixed by checking if the folio returned by filemap is the valid swap cache folio after acquiring the folio lock. Another similar race is possible: filemap_get_folio may return NULL, but folio (A) could be swapped in and then swapped out again using the same swap entry after the lookup. In such a case, folio (A) may remain in the swap cache, so it must be moved too: CPU1 CPU2 userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1, and S1 is not in swap cache folio = filemap_get_folio(S1) // Got NULL ... < interrupted again> ... <swapin folio A and free S1> <swapout folio A re-using S1> move_swap_pte double_pt_lock is_pte_pages_stable // Check passed because src_pte == S1 folio_move_anon_rmap(...) // folio A is ignored !!! Fix this by checking the swap cache again after acquiring the src_pte lock. And to avoid the filemap overhead, we check swap_map directly [2]. The SWP_SYNCHRONOUS_IO path does make the problem more complex, but so far we don't need to worry about that, since folios can only be exposed to the swap cache in the swap out path, and this is covered in this patch by checking the swap cache again after acquiring the src_pte lock. Testing with a simple C program that allocates and moves several GB of memory did not show any observable performance change.

[PATCH 1/2] crypto: x86/aegis - Fix sleeping when disallowed on PREEMPT_RT

by Eric Biggers

skcipher_walk_done() can call kfree(), which takes a spinlock, which makes it incorrect to call while preemption is disabled on PREEMPT_RT. Therefore, end the kernel-mode FPU section before calling skcipher_walk_done(), and restart it afterwards. Moreover, pass atomic=false to skcipher_walk_aead_encrypt() instead of atomic=true. The point of atomic=true was to make skcipher_walk_done() safe to call while in a kernel-mode FPU section, but that does not actually work. So just use the usual atomic=false.

[PATCH v5 1/4] scsi: fnic: Fix crash in fnic_wq_cmpl_handler when FDMI times out

by Karan Tilak Kumar

When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to send ABTS for each of them. On send completion, this causes an attempt to free the same frame twice that leads to a crash. Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS logic accordingly. Tested by checking MDS for FDMI information. Tested by using instrumented driver to: Drop PLOGI response Drop RHBA response Drop RPA response Drop RHBA and RPA response Drop PLOGI response + ABTS response Drop RHBA response + ABTS response Drop RPA response + ABTS response Drop RHBA and RPA response + ABTS response for both of them Fixes: 09c1e6ab4ab2 ("scsi: fnic: Add and integrate support for FDMI") Reviewed-by: Sesidhar Baddela <sebaddel(a)cisco.com> Reviewed-by: Arulprabhu Ponnusamy <arulponn(a)cisco.com> Reviewed-by: Gian Carlo Boffa <gcboffa(a)cisco.com> Tested-by: Arun Easi <aeasi(a)cisco.com> Co-developed-by: Arun Easi <aeasi(a)cisco.com> Signed-off-by: Arun Easi <aeasi(a)cisco.com> Tested-by: Karan Tilak Kumar <kartilak(a)cisco.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Karan Tilak Kumar <kartilak(a)cisco.com> --- Changes between v4 and v5: - Incorporate review comments from John: - Refactor patches Changes between v3 and v4: - Incorporate review comments from Dan: - Remove comments from Cc tag Changes between v2 and v3: - Incorporate review comments from Dan: - Add Cc to stable Changes between v1 and v2: - Incorporate review comments from Dan: - Add Fixes tag --- drivers/scsi/fnic/fdls_disc.c | 113 +++++++++++++++++++++++++--------- drivers/scsi/fnic/fnic.h | 2 +- drivers/scsi/fnic/fnic_fdls.h | 1 + 3 files changed, 87 insertions(+), 29 deletions(-) diff --git a/drivers/scsi/fnic/fdls_disc.c b/drivers/scsi/fnic/fdls_disc.c index c2b6f4eb338e..0ee1b74967b9 100644 --- a/drivers/scsi/fnic/fdls_disc.c +++ b/drivers/scsi/fnic/fdls_disc.c @@ -763,47 +763,69 @@ static void fdls_send_fabric_abts(struct fnic_iport_s *iport) iport->fabric.timer_pending = 1; } -static void fdls_send_fdmi_abts(struct fnic_iport_s *iport) +static uint8_t *fdls_alloc_init_fdmi_abts_frame(struct fnic_iport_s *iport, + uint16_t oxid) { - uint8_t *frame; + struct fc_frame_header *pfdmi_abts; uint8_t d_id[3]; + uint8_t *frame; struct fnic *fnic = iport->fnic; - struct fc_frame_header *pfabric_abts; - unsigned long fdmi_tov; - uint16_t oxid; - uint16_t frame_size = FNIC_ETH_FCOE_HDRS_OFFSET + - sizeof(struct fc_frame_header); frame = fdls_alloc_frame(iport); if (frame == NULL) { FNIC_FCS_DBG(KERN_ERR, fnic->host, fnic->fnic_num, "Failed to allocate frame to send FDMI ABTS"); - return; + return NULL; } - pfabric_abts = (struct fc_frame_header *) (frame + FNIC_ETH_FCOE_HDRS_OFFSET); + pfdmi_abts = (struct fc_frame_header *) (frame + FNIC_ETH_FCOE_HDRS_OFFSET); fdls_init_fabric_abts_frame(frame, iport); hton24(d_id, FC_FID_MGMT_SERV); - FNIC_STD_SET_D_ID(*pfabric_abts, d_id); + FNIC_STD_SET_D_ID(*pfdmi_abts, d_id); + FNIC_STD_SET_OX_ID(*pfdmi_abts, oxid); + + return frame; +} + +static void fdls_send_fdmi_abts(struct fnic_iport_s *iport) +{ + uint8_t *frame; + unsigned long fdmi_tov; + uint16_t frame_size = FNIC_ETH_FCOE_HDRS_OFFSET + + sizeof(struct fc_frame_header); if (iport->fabric.fdmi_pending & FDLS_FDMI_PLOGI_PENDING) { - oxid = iport->active_oxid_fdmi_plogi; - FNIC_STD_SET_OX_ID(*pfabric_abts, oxid); + frame = fdls_alloc_init_fdmi_abts_frame(iport, + iport->active_oxid_fdmi_plogi); + if (frame == NULL) + return; + fnic_send_fcoe_frame(iport, frame, frame_size); } else { if (iport->fabric.fdmi_pending & FDLS_FDMI_REG_HBA_PENDING) { - oxid = iport->active_oxid_fdmi_rhba; - FNIC_STD_SET_OX_ID(*pfabric_abts, oxid); + frame = fdls_alloc_init_fdmi_abts_frame(iport, + iport->active_oxid_fdmi_rhba); + if (frame == NULL) + return; + fnic_send_fcoe_frame(iport, frame, frame_size); } if (iport->fabric.fdmi_pending & FDLS_FDMI_RPA_PENDING) { - oxid = iport->active_oxid_fdmi_rpa; - FNIC_STD_SET_OX_ID(*pfabric_abts, oxid); + frame = fdls_alloc_init_fdmi_abts_frame(iport, + iport->active_oxid_fdmi_rpa); + if (frame == NULL) { + if (iport->fabric.fdmi_pending & FDLS_FDMI_REG_HBA_PENDING) + goto arm_timer; + else + return; + } + fnic_send_fcoe_frame(iport, frame, frame_size); } } +arm_timer: fdmi_tov = jiffies + msecs_to_jiffies(2 * iport->e_d_tov); mod_timer(&iport->fabric.fdmi_timer, round_jiffies(fdmi_tov)); iport->fabric.fdmi_pending |= FDLS_FDMI_ABORT_PENDING; @@ -2244,6 +2266,21 @@ void fdls_fabric_timer_callback(struct timer_list *t) spin_unlock_irqrestore(&fnic->fnic_lock, flags); } +void fdls_fdmi_retry_plogi(struct fnic_iport_s *iport) +{ + struct fnic *fnic = iport->fnic; + + iport->fabric.fdmi_pending = 0; + /* If max retries not exhausted, start over from fdmi plogi */ + if (iport->fabric.fdmi_retry < FDLS_FDMI_MAX_RETRY) { + iport->fabric.fdmi_retry++; + FNIC_FCS_DBG(KERN_INFO, fnic->host, fnic->fnic_num, + "Retry FDMI PLOGI.

[PATCH 1/1] drm/i915/dp: Refine TPS4-based HBR3 rejection and add quirk to limit eDP to HBR2

by Ankit Nautiyal

Refine the logic introduced in commit 584cf613c24a ("drm/i915/dp: Reject HBR3 when sink doesn't support TPS4") to allow HBR3 on eDP panels that report DPCD revision 1.4, even if TPS4 is not supported. This aligns with the DisplayPort specification, which does not mandate TPS4 support for eDP with DPCD rev 1.4. This change avoids regressions on panels that require HBR3 to operate at their native resolution but do not advertise TPS4 support. Additionally, some ICL/TGL platforms with combo PHY ports suffer from signal integrity issues at HBR3. While certain systems include a Parade PS8461 mux to mitigate this, its presence cannot be reliably detected. Furthermore, broken or missing VBT entries make it unsafe to rely on VBT for enforcing link rate limits. To address the HBR3-related issues on such platforms and eDP panels, introduce a device specific quirk to cap the eDP link rate to HBR2 (540000 kHz). This will override any higher advertised rates from the sink or DPCD for specific devices. Currently, the quirk is added for Dell XPS 13 7390 2-in-1 which is reported in gitlab issue #5969 [1].

[PATCH v3] drm/framebuffer: Acquire internal references on GEM handles

by Thomas Zimmermann

Acquire GEM handles in drm_framebuffer_init() and release them in the corresponding drm_framebuffer_cleanup(). Ties the handle's lifetime to the framebuffer. Not all GEM buffer objects have GEM handles. If not set, no refcounting takes place. This is the case for some fbdev emulation. This is not a problem as these GEM objects do not use dma-bufs and drivers will not release them while fbdev emulation is running. Framebuffer flags keep a bit per color plane of which the framebuffer holds a GEM handle reference. As all drivers use drm_framebuffer_init(), they will now all hold dma-buf references as fixed in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers"). In the GEM framebuffer helpers, restore the original ref counting on buffer objects. As the helpers for handle refcounting are now no longer called from outside the DRM core, unexport the symbols. v3: - don't mix internal flags with mode flags (Christian) v2: - track framebuffer handle refs by flag - drop gma500 cleanup (Christian) Signed-off-by: Thomas Zimmermann <tzimmermann(a)suse.de> Fixes: 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers") Reported-by: Bert Karwatzki <spasswolf(a)web.de> Closes: https://lore.kernel.org/dri-devel/20250703115915.3096-1-spasswolf@web.de/ Tested-by: Bert Karwatzki <spasswolf(a)web.de> Tested-by: Mario Limonciello <superm1(a)kernel.org> Cc: Thomas Zimmermann <tzimmermann(a)suse.de> Cc: Anusha Srivatsa <asrivats(a)redhat.com> Cc: Christian König <christian.koenig(a)amd.com> Cc: Maarten Lankhorst <maarten.lankhorst(a)linux.intel.com> Cc: Maxime Ripard <mripard(a)kernel.org> Cc: Sumit Semwal <sumit.semwal(a)linaro.org> Cc: "Christian König" <christian.koenig(a)amd.com> Cc: linux-media(a)vger.kernel.org Cc: dri-devel(a)lists.freedesktop.org Cc: linaro-mm-sig(a)lists.linaro.org Cc: <stable(a)vger.kernel.org> --- drivers/gpu/drm/drm_framebuffer.c | 31 ++++++++++++++-- drivers/gpu/drm/drm_gem.c | 38 ++++++++++++-------- drivers/gpu/drm/drm_gem_framebuffer_helper.c | 16 ++++----- drivers/gpu/drm/drm_internal.h | 2 +- include/drm/drm_framebuffer.h | 7 ++++ 5 files changed, 68 insertions(+), 26 deletions(-) diff --git a/drivers/gpu/drm/drm_framebuffer.c b/drivers/gpu/drm/drm_framebuffer.c index b781601946db..63a70f285cce 100644 --- a/drivers/gpu/drm/drm_framebuffer.c +++ b/drivers/gpu/drm/drm_framebuffer.c @@ -862,11 +862,23 @@ EXPORT_SYMBOL_FOR_TESTS_ONLY(drm_framebuffer_free); int drm_framebuffer_init(struct drm_device *dev, struct drm_framebuffer *fb, const struct drm_framebuffer_funcs *funcs) { + unsigned int i; int ret; + bool exists; if (WARN_ON_ONCE(fb->dev != dev || !fb->format)) return -EINVAL; + for (i = 0; i < fb->format->num_planes; i++) { + if (drm_WARN_ON_ONCE(dev, fb->internal_flags & DRM_FRAMEBUFFER_HAS_HANDLE_REF(i))) + fb->internal_flags &= ~DRM_FRAMEBUFFER_HAS_HANDLE_REF(i); + if (fb->obj[i]) { + exists = drm_gem_object_handle_get_if_exists_unlocked(fb->obj[i]); + if (exists) + fb->internal_flags |= DRM_FRAMEBUFFER_HAS_HANDLE_REF(i); + } + } + INIT_LIST_HEAD(&fb->filp_head); fb->funcs = funcs; @@ -875,7 +887,7 @@ int drm_framebuffer_init(struct drm_device *dev, struct drm_framebuffer *fb, ret = __drm_mode_object_add(dev, &fb->base, DRM_MODE_OBJECT_FB, false, drm_framebuffer_free); if (ret) - goto out; + goto err; mutex_lock(&dev->mode_config.fb_lock); dev->mode_config.num_fb++; @@ -883,7 +895,16 @@ int drm_framebuffer_init(struct drm_device *dev, struct drm_framebuffer *fb, mutex_unlock(&dev->mode_config.fb_lock); drm_mode_object_register(dev, &fb->base); -out: + + return 0; + +err: + for (i = 0; i < fb->format->num_planes; i++) { + if (fb->internal_flags & DRM_FRAMEBUFFER_HAS_HANDLE_REF(i)) { + drm_gem_object_handle_put_unlocked(fb->obj[i]); + fb->internal_flags &= ~DRM_FRAMEBUFFER_HAS_HANDLE_REF(i); + } + } return ret; } EXPORT_SYMBOL(drm_framebuffer_init); @@ -960,6 +981,12 @@ EXPORT_SYMBOL(drm_framebuffer_unregister_private); void drm_framebuffer_cleanup(struct drm_framebuffer *fb) { struct drm_device *dev = fb->dev; + unsigned int i; + + for (i = 0; i < fb->format->num_planes; i++) { + if (fb->internal_flags & DRM_FRAMEBUFFER_HAS_HANDLE_REF(i)) + drm_gem_object_handle_put_unlocked(fb->obj[i]); + } mutex_lock(&dev->mode_config.fb_lock); list_del(&fb->head); diff --git a/drivers/gpu/drm/drm_gem.c b/drivers/gpu/drm/drm_gem.c index bc505d938b3e..41cdab6088ae 100644 --- a/drivers/gpu/drm/drm_gem.c +++ b/drivers/gpu/drm/drm_gem.c @@ -224,23 +224,34 @@ static void drm_gem_object_handle_get(struct drm_gem_object *obj) } /** - * drm_gem_object_handle_get_unlocked - acquire reference on user-space handles + * drm_gem_object_handle_get_if_exists_unlocked - acquire reference on user-space handle, if any * @obj: GEM object * - * Acquires a reference on the GEM buffer object's handle.

[PATCH] comedi: comedi_test: Fix possible deletion of uninitialized timers

by Ian Abbott

In `waveform_common_attach()`, the two timers `&devpriv->ai_timer` and `&devpriv->ao_timer` are initialized after the allocation of the device private data by `comedi_alloc_devpriv()` and the subdevices by `comedi_alloc_subdevices()`. The function may return with an error between those function calls. In that case, `waveform_detach()` will be called by the Comedi core to clean up. The check that `waveform_detach()` uses to decide whether to delete the timers is incorrect. It only checks that the device private data was allocated, but that does not guarantee that the timers were initialized. It also needs to check that the subdevices were allocated. Fix it.

[PATCH v3] wifi: wilc1000: Add error handling for wilc_sdio_cmd52()

by Wentao Liang

The wilc_sdio_read_size() calls wilc_sdio_cmd52() but does not check the return value. This could lead to execution with potentially invalid data if wilc_sdio_cmd52() fails. A proper implementation can be found in wilc_sdio_read_reg(). Add error handling for wilc_sdio_cmd52(). If wilc_sdio_cmd52() fails, log an error message via dev_err().

[PATCH AUTOSEL 5.4 1/3] Revert "ACPI: battery: negate current when discharging"

by Sasha Levin

From: "Rafael J. Wysocki" <rafael.j.wysocki(a)intel.com> [ Upstream commit de1675de39aa945bad5937d1fde4df3682670639 ] Revert commit 234f71555019 ("ACPI: battery: negate current when discharging") breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud. Perhaps it breaks more, but those are the two that have been tested. Reported-by: Matthew Schwartz <matthew.schwartz(a)linux.dev> Closes: https://lore.kernel.org/linux-acpi/87C1B2AF-D430-4568-B620-14B941A8ABA4@lin… Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES**, this commit should be backported to stable kernel trees. ## Extensive Explanation: ### 1. **Critical Userspace Regression Fix** This revert fixes a critical regression that breaks userspace applications. The commit message explicitly states that the original change "breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud." This is a clear violation of the kernel's "no userspace regressions" rule, which is one of the most fundamental principles in kernel development. ### 2. **Code Analysis Shows ABI Change** Looking at the code changes: ```c // The problematic code that was added (and is now being removed): if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && acpi_battery_handle_discharging(battery) == POWER_SUPPLY_STATUS_DISCHARGING) val->intval = -val->intval; ``` This code was changing the sign of the current value when discharging, which altered the userspace-visible ABI. Even if the original behavior didn't match documentation, changing it broke existing applications that depended on the long-standing behavior. ### 3. **Simple and Safe Revert** The commit is a clean revert that: - Removes the problematic sign negation logic - Restores the original behavior that userspace applications expect - Is self-contained to the `acpi_battery_get_property()` function - Has minimal risk of introducing new issues ### 4. **Meets Stable Kernel Criteria** According to stable kernel rules, this commit qualifies because it: - **Fixes a real bug** that users are hitting (broken battery monitoring in Steam and MangoHud) - **Is obviously correct** (it's a revert of a change that broke userspace) - **Is small and contained** (only affects the ACPI battery property reporting) - **Has been tested** (the reporter confirmed the issue) - **Fixes a regression** (restores previous working behavior) ### 5. **Comparison to Similar Commits** Looking at the historical commits marked with "Backport Status: YES", they share similar characteristics: - Fix actual problems affecting users - Are relatively small and contained changes - Don't introduce new features or architectural changes - Focus on fixing specific issues This revert fits perfectly into this pattern as it's fixing a specific userspace compatibility issue without introducing any new functionality. ### 6. **Timing Considerations** The original problematic commit (234f71555019) was from May 8, 2025, and this revert is from July 3, 2025.

[PATCH AUTOSEL 5.10 1/3] Revert "ACPI: battery: negate current when discharging"

by Sasha Levin

From: "Rafael J. Wysocki" <rafael.j.wysocki(a)intel.com> [ Upstream commit de1675de39aa945bad5937d1fde4df3682670639 ] Revert commit 234f71555019 ("ACPI: battery: negate current when discharging") breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud. Perhaps it breaks more, but those are the two that have been tested. Reported-by: Matthew Schwartz <matthew.schwartz(a)linux.dev> Closes: https://lore.kernel.org/linux-acpi/87C1B2AF-D430-4568-B620-14B941A8ABA4@lin… Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES**, this commit should be backported to stable kernel trees. ## Extensive Explanation: ### 1. **Critical Userspace Regression Fix** This revert fixes a critical regression that breaks userspace applications. The commit message explicitly states that the original change "breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud." This is a clear violation of the kernel's "no userspace regressions" rule, which is one of the most fundamental principles in kernel development. ### 2. **Code Analysis Shows ABI Change** Looking at the code changes: ```c // The problematic code that was added (and is now being removed): if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && acpi_battery_handle_discharging(battery) == POWER_SUPPLY_STATUS_DISCHARGING) val->intval = -val->intval; ``` This code was changing the sign of the current value when discharging, which altered the userspace-visible ABI. Even if the original behavior didn't match documentation, changing it broke existing applications that depended on the long-standing behavior. ### 3. **Simple and Safe Revert** The commit is a clean revert that: - Removes the problematic sign negation logic - Restores the original behavior that userspace applications expect - Is self-contained to the `acpi_battery_get_property()` function - Has minimal risk of introducing new issues ### 4. **Meets Stable Kernel Criteria** According to stable kernel rules, this commit qualifies because it: - **Fixes a real bug** that users are hitting (broken battery monitoring in Steam and MangoHud) - **Is obviously correct** (it's a revert of a change that broke userspace) - **Is small and contained** (only affects the ACPI battery property reporting) - **Has been tested** (the reporter confirmed the issue) - **Fixes a regression** (restores previous working behavior) ### 5. **Comparison to Similar Commits** Looking at the historical commits marked with "Backport Status: YES", they share similar characteristics: - Fix actual problems affecting users - Are relatively small and contained changes - Don't introduce new features or architectural changes - Focus on fixing specific issues This revert fits perfectly into this pattern as it's fixing a specific userspace compatibility issue without introducing any new functionality. ### 6. **Timing Considerations** The original problematic commit (234f71555019) was from May 8, 2025, and this revert is from July 3, 2025. If the original commit made it into any stable releases, those stable trees would need this revert to prevent userspace breakage. ### Conclusion: This is a textbook example of a commit that should be backported to stable kernels.

+ mm-check-if-folio-has-valid-mapcount-before-folio_test_anonksm-when-necessary.patch added to mm-new branch

by Andrew Morton

The patch titled Subject: mm: check if folio has valid mapcount before folio_test_{anon,ksm}() when necessary has been added to the -mm mm-new branch. Its filename is mm-check-if-folio-has-valid-mapcount-before-folio_test_anonksm-when-necessary.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-new branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Note, mm-new is a provisional staging ground for work-in-progress patches, and acceptance into mm-new is a notification for others take notice and to finish up reviews. Please do not hesitate to respond to review feedback and post updated versions to replace or incrementally fixup patches in mm-new. Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Harry Yoo <harry.yoo(a)oracle.com> Subject: mm: check if folio has valid mapcount before folio_test_{anon,ksm}() when necessary Date: Mon, 7 Jul 2025 21:07:40 +0900 folio_test_anon() and folio_test_ksm() may return false positives when the folio is a typed page (except hugetlb), because lower bits of folio->mapping field can be set even if it doesn't mean FOLIO_MAPPING_* flags. To avoid false positives, folio_test_{anon,ksm}() should be called only if !page_has_type(&folio->page) || folio_test_hugetlb(folio). However, the check can be skipped if a folio is or will be mapped to userspace because typed pages that are not hugetlb folios cannot be mapped to userspace. As folio_expected_ref_count() already does the check, introduce a helper function folio_has_mapcount() and use it in folio_expected_ref_count() and stable_page_flags(). Update the comment in FOLIO_MAPPING_* flags accordingly.

The amd64_edac module logs DIMM sizes on a per-UMC per-CS granularity during init using these two registers. Currently, the module primarily considers only the Address Mask register for computing DIMM sizes. The Secondary Address Mask register is only considered for odd CS. Additionally, if it has been considered, the Address Mask register is ignored altogether for that CS. For power-of-two DIMMs i.e. DIMMs whose total capacity is a power of two (32GB, 64GB, etc), this is not an issue since only the Address Mask register is used. For non-power-of-two DIMMs i.e., DIMMs whose total capacity is not a power of two (48GB, 96GB, etc), however, the Secondary Address Mask register is used in conjunction with the Address Mask register. However, since the module only considers either of the two registers for a CS, the size computed by the module is incorrect. The Secondary Address Mask register is not considered for even CS, and the Address Mask register is not considered for odd CS. Introduce a new helper function so that both Address Mask and Secondary Address Mask registers are considered, when valid, for computing DIMM sizes. Furthermore, also rename some variables for greater clarity.

[PATCH 2/2] platform/x86: ideapad-laptop: Fix kbd backlight not remembered among boots

by Rong Zhang

On some models supported by ideapad-laptop, the HW/FW can remember the state of keyboard backlight among boots. However, it is always turned off while shutting down, as a side effect of the LED class device unregistering sequence.

[PATCH 1/2] platform/x86: ideapad-laptop: Fix FnLock not remembered among boots

by Rong Zhang

On devices supported by ideapad-laptop, the HW/FW can remember the FnLock state among boots. However, since the introduction of the FnLock LED class device, it is turned off while shutting down, as a side effect of the LED class device unregistering sequence. Many users always turn on FnLock because they use function keys much more frequently than multimedia keys. The behavior change is inconvenient for them. Thus, set LED_RETAIN_AT_SHUTDOWN on the LED class device so that the FnLock state gets remembered, which also aligns with the behavior of manufacturer utilities on Windows.

[PATCH] comedi: Fix initialization of data for instructions that write to subdevice

by Ian Abbott

Some Comedi subdevice instruction handlers are known to access instruction data elements beyond the first `insn->n` elements in some cases. The `do_insn_ioctl()` and `do_insnlist_ioctl()` functions allocate at least `MIN_SAMPLES` (16) data elements to deal with this, but they do not initialize all of that. For Comedi instruction codes that write to the subdevice, the first `insn->n` data elements are copied from user-space, but the remaining elements are left uninitialized. That could be a problem if the subdevice instruction handler reads the uninitialized data. Ensure that the first `MIN_SAMPLES` elements are initialized before calling these instruction handlers, filling the uncopied elements with 0. For `do_insnlist_ioctl()`, the same data buffer elements are used for handling a list of instructions, so ensure the first `MIN_SAMPLES` elements are initialized for each instruction that writes to the subdevice.

[PATCH] comedi: Fix use of uninitialized data in insn_rw_emulate_bits()

by Ian Abbott

For Comedi `INSN_READ` and `INSN_WRITE` instructions on "digital" subdevices (subdevice types `COMEDI_SUBD_DI`, `COMEDI_SUBD_DO`, and `COMEDI_SUBD_DIO`), it is common for the subdevice driver not to have `insn_read` and `insn_write` handler functions, but to have an `insn_bits` handler function for handling Comedi `INSN_BITS` instructions. In that case, the subdevice's `insn_read` and/or `insn_write` function handler pointers are set to point to the `insn_rw_emulate_bits()` function by `__comedi_device_postconfig()`. For `INSN_WRITE`, `insn_rw_emulate_bits()` currently assumes that the supplied `data[0]` value is a valid copy from user memory. It will at least exist because `do_insnlist_ioctl()` and `do_insn_ioctl()` in "comedi_fops.c" ensure at lease `MIN_SAMPLES` (16) elements are allocated. However, if `insn->n` is 0 (which is allowable for `INSN_READ` and `INSN_WRITE` instructions, then `data[0]` may contain uninitialized data, and certainly contains invalid data, possibly from a different instruction in the array of instructions handled by `do_insnlist_ioctl()`. This will result in an incorrect value being written to the digital output channel (or to the digital input/output channel if configured as an output), and may be reflected in the internal saved state of the channel. Fix it by returning 0 early if `insn->n` is 0, before reaching the code that accesses `data[0]`. Previously, the function always returned 1 on success, but it is supposed to be the number of data samples actually read or written up to `insn->n`, which is 0 in this case.

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 net] net: phy: realtek: Reset after clock enable

by Sebastian Reichel

On Radxa ROCK 4D boards we are seeing some issues with PHY detection and stability (e.g. link loss, or not capable of transceiving packages) after new board revisions switched from a dedicated crystal to providing the 25 MHz PHY input clock from the SoC instead. This board is using a RTL8211F PHY, which is connected to an always-on regulator. Unfortunately the datasheet does not explicitly mention the power-up sequence regarding the clock, but it seems to assume that the clock is always-on (i.e. dedicated crystal). By doing an explicit reset after enabling the clock, the issue on the boards could no longer be observed.

[PATCH] comedi: das6402: Fix bit shift out of bounds

by Ian Abbott

When checking for a supported IRQ number, the following test is used: /* IRQs 2,3,5,6,7, 10,11,15 are valid for "enhanced" mode */ if ((1 << it->options[1]) & 0x8cec) { However, `it->options[i]` is an unchecked `int` value from userspace, so the shift amount could be negative or out of bounds. Fix the test by requiring `it->options[1]` to be within bounds before proceeding with the original test. Valid `it->options[1]` values that select the IRQ will be in the range [1,15].

This happens before the VMA lock and rmap locks are taken - which is too early, it allows racing VMA-locked page faults in our process and racing rmap walks from other processes to cause page tables to be shared again before we actually perform the split. Fix it by explicitly calling into the hugetlb unshare logic from __split_vma() in the same place where THP splitting also happens. At that point, both the VMA and the rmap(s) are write-locked. An annoying detail is that we can now call into the helper hugetlb_unshare_pmds() from two different locking contexts: 1. from hugetlb_split(), holding: - mmap lock (exclusively) - VMA lock - file rmap lock (exclusively) 2. hugetlb_unshare_all_pmds(), which I think is designed to be able to call us with only the mmap lock held (in shared mode), but currently only runs while holding mmap lock (exclusively) and VMA lock Backporting note: This commit fixes a racy protection that was introduced in commit b30c14cd6102 ("hugetlb: unshare some PMDs when splitting VMAs"); that commit claimed to fix an issue introduced in 5.13, but it should actually also go all the way back.

[PATCH] comedi: Fix some signed shift left operations

by Ian Abbott

Correct some left shifts of the signed integer constant 1 by some unsigned number less than 32. Change the constant to 1U to avoid shifting a 1 into the sign bit. The corrected functions are comedi_dio_insn_config(), comedi_dio_update_state(), and __comedi_device_postconfig(). Fixes: e523c6c86232 ("staging: comedi: drivers: introduce comedi_dio_insn_config()") Fixes: 05e60b13a36b ("staging: comedi: drivers: introduce comedi_dio_update_state()") Fixes: 09567cb4373e ("staging: comedi: initialize subdevice s->io_bits in postconfig") Cc: <stable(a)vger.kernel.org> # 5.13+ Signed-off-by: Ian Abbott <abbotti(a)mev.co.uk> --- drivers/comedi/drivers.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/drivers/comedi/drivers.c b/drivers/comedi/drivers.c index 376130bfba8a..922fe20738ef 100644 --- a/drivers/comedi/drivers.c +++ b/drivers/comedi/drivers.c @@ -339,10 +339,10 @@ int comedi_dio_insn_config(struct comedi_device *dev, unsigned int *data, unsigned int mask) { - unsigned int chan_mask = 1 << CR_CHAN(insn->chanspec); + unsigned int chan = CR_CHAN(insn->chanspec); - if (!mask) - mask = chan_mask; + if (!mask && chan < 32) + mask = 1U << chan; switch (data[0]) { case INSN_CONFIG_DIO_INPUT: @@ -382,7 +382,7 @@ EXPORT_SYMBOL_GPL(comedi_dio_insn_config); unsigned int comedi_dio_update_state(struct comedi_subdevice *s, unsigned int *data) { - unsigned int chanmask = (s->n_chan < 32) ?

[PATCH v2] drm/bridge: tc358767: fix uninitialized variable regression

by Luca Ceresoli

Commit a59a27176914 ("drm/bridge: tc358767: convert to devm_drm_bridge_alloc() API") split tc_probe_bridge_endpoint() in two functions, thus duplicating the loop over the endpoints in each of those functions. However it missed duplicating the of_graph_parse_endpoint() call which initializes the struct of_endpoint, resulting in an uninitialized read.

[PATCH v2] drm/framebuffer: Acquire internal references on GEM handles

by Thomas Zimmermann

Acquire GEM handles in drm_framebuffer_init() and release them in the corresponding drm_framebuffer_cleanup(). Ties the handle's lifetime to the framebuffer. Not all GEM buffer objects have GEM handles. If not set, no refcounting takes place. This is the case for some fbdev emulation. This is not a problem as these GEM objects do not use dma-bufs and drivers will not release them while fbdev emulation is running. Framebuffer flags keep a bit per color plane of which the framebuffer holds a GEM handle reference. As all drivers use drm_framebuffer_init(), they will now all hold dma-buf references as fixed in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers"). In the GEM framebuffer helpers, restore the original ref counting on buffer objects. As the helpers for handle refcounting are now no longer called from outside the DRM core, unexport the symbols. v2: - track framebuffer handle refs by flag - drop gma500 cleanup (Christian) Signed-off-by: Thomas Zimmermann <tzimmermann(a)suse.de> Fixes: 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers") Reported-by: Bert Karwatzki <spasswolf(a)web.de> Closes: https://lore.kernel.org/dri-devel/20250703115915.3096-1-spasswolf@web.de/ Tested-by: Bert Karwatzki <spasswolf(a)web.de> Tested-by: Mario Limonciello <superm1(a)kernel.org> Cc: Thomas Zimmermann <tzimmermann(a)suse.de> Cc: Anusha Srivatsa <asrivats(a)redhat.com> Cc: Christian König <christian.koenig(a)amd.com> Cc: Maarten Lankhorst <maarten.lankhorst(a)linux.intel.com> Cc: Maxime Ripard <mripard(a)kernel.org> Cc: Sumit Semwal <sumit.semwal(a)linaro.org> Cc: "Christian König" <christian.koenig(a)amd.com> Cc: linux-media(a)vger.kernel.org Cc: dri-devel(a)lists.freedesktop.org Cc: linaro-mm-sig(a)lists.linaro.org Cc: <stable(a)vger.kernel.org> --- drivers/gpu/drm/drm_framebuffer.c | 31 ++++++++++++++-- drivers/gpu/drm/drm_gem.c | 38 ++++++++++++-------- drivers/gpu/drm/drm_gem_framebuffer_helper.c | 16 ++++----- drivers/gpu/drm/drm_internal.h | 2 +- drivers/gpu/drm/drm_modeset_helper.c | 2 +- include/drm/drm_framebuffer.h | 9 +++++ 6 files changed, 71 insertions(+), 27 deletions(-) diff --git a/drivers/gpu/drm/drm_framebuffer.c b/drivers/gpu/drm/drm_framebuffer.c index b781601946db..23b56cde21d7 100644 --- a/drivers/gpu/drm/drm_framebuffer.c +++ b/drivers/gpu/drm/drm_framebuffer.c @@ -862,11 +862,23 @@ EXPORT_SYMBOL_FOR_TESTS_ONLY(drm_framebuffer_free); int drm_framebuffer_init(struct drm_device *dev, struct drm_framebuffer *fb, const struct drm_framebuffer_funcs *funcs) { + unsigned int i; int ret; + bool exists; if (WARN_ON_ONCE(fb->dev != dev || !fb->format)) return -EINVAL; + for (i = 0; i < fb->format->num_planes; i++) { + if (drm_WARN_ON_ONCE(dev, fb->flags & DRM_FRAMEBUFFER_HAS_HANDLE_REF(i))) + fb->flags &= ~DRM_FRAMEBUFFER_HAS_HANDLE_REF(i); + if (fb->obj[i]) { + exists = drm_gem_object_handle_get_if_exists_unlocked(fb->obj[i]); + if (exists) + fb->flags |= DRM_FRAMEBUFFER_HAS_HANDLE_REF(i); + } + } + INIT_LIST_HEAD(&fb->filp_head); fb->funcs = funcs; @@ -875,7 +887,7 @@ int drm_framebuffer_init(struct drm_device *dev, struct drm_framebuffer *fb, ret = __drm_mode_object_add(dev, &fb->base, DRM_MODE_OBJECT_FB, false, drm_framebuffer_free); if (ret) - goto out; + goto err; mutex_lock(&dev->mode_config.fb_lock); dev->mode_config.num_fb++; @@ -883,7 +895,16 @@ int drm_framebuffer_init(struct drm_device *dev, struct drm_framebuffer *fb, mutex_unlock(&dev->mode_config.fb_lock); drm_mode_object_register(dev, &fb->base); -out: + + return 0; + +err: + for (i = 0; i < fb->format->num_planes; i++) { + if (fb->flags & DRM_FRAMEBUFFER_HAS_HANDLE_REF(i)) { + drm_gem_object_handle_put_unlocked(fb->obj[i]); + fb->flags &= ~DRM_FRAMEBUFFER_HAS_HANDLE_REF(i); + } + } return ret; } EXPORT_SYMBOL(drm_framebuffer_init); @@ -960,6 +981,12 @@ EXPORT_SYMBOL(drm_framebuffer_unregister_private); void drm_framebuffer_cleanup(struct drm_framebuffer *fb) { struct drm_device *dev = fb->dev; + unsigned int i; + + for (i = 0; i < fb->format->num_planes; i++) { + if (fb->flags & DRM_FRAMEBUFFER_HAS_HANDLE_REF(i)) + drm_gem_object_handle_put_unlocked(fb->obj[i]); + } mutex_lock(&dev->mode_config.fb_lock); list_del(&fb->head); diff --git a/drivers/gpu/drm/drm_gem.c b/drivers/gpu/drm/drm_gem.c index bc505d938b3e..41cdab6088ae 100644 --- a/drivers/gpu/drm/drm_gem.c +++ b/drivers/gpu/drm/drm_gem.c @@ -224,23 +224,34 @@ static void drm_gem_object_handle_get(struct drm_gem_object *obj) } /** - * drm_gem_object_handle_get_unlocked - acquire reference on user-space handles + * drm_gem_object_handle_get_if_exists_unlocked - acquire reference on user-space handle, if any * @obj: GEM object * - * Acquires a reference on the GEM buffer object's handle.

[PATCH v1 mm-hotfixes] mm/zsmalloc: do not pass __GFP_MOVABLE if CONFIG_COMPACTION=n

by Harry Yoo

Commit 48b4800a1c6a ("zsmalloc: page migration support") added support for migrating zsmalloc pages using the movable_operations migration framework. However, the commit did not take into account that zsmalloc supports migration only when CONFIG_COMPACTION is enabled. Tracing shows that zsmalloc was still passing the __GFP_MOVABLE flag even when compaction is not supported. This can result in unmovable pages being allocated from movable page blocks (even without stealing page blocks), ZONE_MOVABLE and CMA area. Clear the __GFP_MOVABLE flag when !IS_ENABLED(CONFIG_COMPACTION).

[PATCH v1] arm64: dts: freescale: imx8mm-verdin: Keep LDO5 always on

by Francesco Dolcini

From: Francesco Dolcini <francesco.dolcini(a)toradex.com> LDO5 regulator is used to power the i.MX8MM NVCC_SD2 I/O supply, that is used for the SD2 card interface and also for some GPIOs. When the SD card interface is not enabled the regulator subsystem could turn off this supply, since it is not used anywhere else, however this will also remove the power to some other GPIOs, for example one I/O that is used to power the ethernet phy, leading to a non working ethernet interface.

[PATCH] crypto: s390/sha - Fix uninitialized variable in SHA-1 and SHA-2

by Eric Biggers

Commit 88c02b3f79a6 ("s390/sha3: Support sha3 performance enhancements") added the field s390_sha_ctx::first_message_part and made it be used by s390_sha_update_blocks(). At the time, s390_sha_update_blocks() was used by all the s390 SHA-1, SHA-2, and SHA-3 algorithms. However, only the initialization functions for SHA-3 were updated, leaving SHA-1 and SHA-2 using first_message_part uninitialized. This could cause e.g. CPACF_KIMD_SHA_512 | CPACF_KIMD_NIP to be used instead of just CPACF_KIMD_NIP. It's unclear why this didn't cause a problem earlier; this bug was found only when UBSAN detected the uninitialized boolean. Perhaps the CPU ignores CPACF_KIMD_NIP for SHA-1 and SHA-2. Regardless, let's fix this. For now just initialize to false, i.e. don't try to "optimize" the SHA state initialization. Note: in 6.16, we need to patch SHA-1, SHA-384, and SHA-512. In 6.15 and earlier, we'll also need to patch SHA-224 and SHA-256, as they hadn't yet been librarified (which incidentally fixed this bug).

[PATCH 5/5] lib/crypto: x86/poly1305: Fix performance regression on short messages

by Eric Biggers

Restore the len >= 288 condition on using the AVX implementation, which was incidentally removed by commit 318c53ae02f2 ("crypto: x86/poly1305 - Add block-only interface"). This check took into account the overhead in key power computation, kernel-mode "FPU", and tail handling associated with the AVX code. Indeed, restoring this check slightly improves performance for len < 256 as measured using poly1305_kunit on an "AMD Ryzen AI 9 365" (Zen 5) CPU: Length Before After ====== ========== ========== 1 30 MB/s 36 MB/s 16 516 MB/s 598 MB/s 64 1700 MB/s 1882 MB/s 127 2265 MB/s 2651 MB/s 128 2457 MB/s 2827 MB/s 200 2702 MB/s 3238 MB/s 256 3841 MB/s 3768 MB/s 511 4580 MB/s 4585 MB/s 512 5430 MB/s 5398 MB/s 1024 7268 MB/s 7305 MB/s 3173 8999 MB/s 8948 MB/s 4096 9942 MB/s 9921 MB/s 16384 10557 MB/s 10545 MB/s While the optimal threshold for this CPU might be slightly lower than 288 (see the len == 256 case), other CPUs would need to be tested too, and these sorts of benchmarks can underestimate the true cost of kernel-mode "FPU". Therefore, for now just restore the 288 threshold.

[PATCH 4/5] lib/crypto: x86/poly1305: Fix register corruption in no-SIMD contexts

by Eric Biggers

Restore the SIMD usability check and base conversion that were removed by commit 318c53ae02f2 ("crypto: x86/poly1305 - Add block-only interface"). This safety check is cheap and is well worth eliminating a footgun. While the Poly1305 functions *should* be called only where SIMD registers are usable, if they are anyway, they should just do the right thing instead of corrupting random tasks' registers and/or computing incorrect MACs. Fixing this is also needed for poly1305_kunit to pass. Just use irq_fpu_usable() instead of the original crypto_simd_usable(), since poly1305_kunit won't rely on crypto_simd_disabled_for_test.

[REGRESSION] - Multiple userspace implementations of battery estimate broken after "ACPI: battery: negate current when discharging"

by Matthew Schwartz

Hello, I installed kernel 6.15.4 to find that my battery estimate on my handheld gaming device was completely inaccurate, instead giving negative values and an unknown estimated battery life in multiple places. After bisecting, I landed on "ACPI: battery: negate current when discharging” as the bad commit. This commit breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud. Perhaps it breaks more, but those are the two I have noticed so far. Thanks, Matthew Schwartz

[PATCH 0/6] mm/damon: fix misc bugs in DAMON modules

by SeongJae Park

From manual code review, I found below bugs in DAMON modules. DAMON sample modules crash if those are enabled at boot time, via kernel command line. A similar issue was found and fixed on DAMON non-sample modules in the past, but we didn't check that for sample modules. DAMON non-sample modules are not setting 'enabled' parameters accordingly when real enabling is failed. Honggyu found and fixed[1] this type of bugs in DAMON sample modules, and my inspection was motivated by the great work. Kudos to Honggyu. Finally, DAMON_RECLIAM is mistakenly losing scheme internal status due to misuse of damon_commit_ctx(). DAMON_LRU_SORT has a similar misuse, but fortunately it is not causing real status loss. Fix the bugs. Since these are similar patterns of bugs that were found in the past, it would be better to add tests or refactor the code, in future. Note that the fix of the second bug for DAMON_STAT is sent separately[2], since it is a fix for a bug in mm-unstable tree at the moment. Also as mentioned above, DAMON_LRU_SORT also has a misuse of damon_commit_ctx(), but it is not causing a real issue, hence the fix is not included in this series. I will post it later.

[PATCH] drm/framebuffer: Acquire internal references on GEM handles

by Thomas Zimmermann

Acquire GEM handles in drm_framebuffer_init() and release them in the corresponding drm_framebuffer_cleanup(). Ties the handle's lifetime to the framebuffer. Not all GEM buffer objects have GEM handles. If not set, no refcounting takes place. This is the case for some fbdev emulation. This is not a problem as these GEM objects do not use dma-bufs and drivers will not release them while fbdev emulation is running. As all drivers use drm_framebuffer_init(), they will now all hold dma-buf references as fixed in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers"). In the GEM framebuffer helpers, restore the original ref counting on buffer objects. As the helpers for handle refcounting are now no longer called from outside the DRM core, unexport the symbols. Gma500 (unnecessarily) clears the framebuffer's GEM-object pointer before calling drm_framebuffer_cleanup(). Remove these lines to make it consistent with the rest of the drivers. It's one of the fbdev emulations with no GEM handle on their buffers. The change to gma500 is therefore rather cosmetic. Tested on i915, amdgpu (by Bert) and gma500. Also tested on i915 plus udl for the original problem with dma-buf sharing.

As most advertising settings are performed in a synchronous context, the (asynchronous) setting of the advertising data is done too late (after enabling the advertising). Move setting of adverstising data from asynchronous response handler into synchronous context to fix ordering of HCI commands.

[PATCH v3 0/3] m68k: Bug fix and cleanup for framebuffer debug console

by Finn Thain

This series has a bug fix for the early bootconsole as well as some related efficiency improvements and cleanup. The relevant code is subject to CONSOLE_DEBUG, which is presently only used with CONFIG_MAC. To test this series (in qemu-system-m68k, for example) it's helpful to enable CONFIG_EARLY_PRINTK and CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER and boot with kernel parameters 'console=ttyS0 earlyprintk keep_bootcon'. --- Changed since v1: - Solved problem with line wrap while scrolling. - Added two additional patches. Changed since v2: - Adopted addq and subq as suggested by Andreas. Finn Thain (3): m68k: Fix lost column on framebuffer debug console m68k: Avoid pointless recursion in debug console rendering m68k: Remove unused "cursor home" code from debug console arch/m68k/kernel/head.S | 73 +++++++++++++++++++++-------------------- 1 file changed, 37 insertions(+), 36 deletions(-) -- 2.45.3

[PATCH 6.15.y v2] mm/vmalloc: fix data race in show_numa_info()

by Jeongjun Park

commit 5c5f0468d172ddec2e333d738d2a1f85402cf0bc upstream.

Howlett" <Liam.Howlett(a)oracle.com> Date: Mon, 16 Jun 2025 14:45:20 -0400 Subject: [PATCH] maple_tree: fix MA_STATE_PREALLOC flag in mas_preallocate() Temporarily clear the preallocation flag when explicitly requesting allocations. 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.
