patch "iio: adc: stm32-adc: fix channel sampling time init" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: adc: stm32-adc: fix channel sampling time init to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. From 174dac5dc800e4e2e4552baf6340846a344d01a3 Mon Sep 17 00:00:00 2001 From: Olivier Moysan <olivier.moysan(a)foss.st.com> Date: Wed, 12 Oct 2022 16:21:58 +0200 Subject: iio: adc: stm32-adc: fix channel sampling time init Fix channel init for ADC generic channel bindings. In generic channel initialization, stm32_adc_smpr_init() is called to initialize channel sampling time. The "st,min-sample-time-ns" property is an optional property. If it is not defined, stm32_adc_smpr_init() is currently skipped. However stm32_adc_smpr_init() must always be called, to force a minimum sampling time for the internal channels, as the minimum sampling time is known. Make stm32_adc_smpr_init() call unconditional.

But now commit 71e2d666ef85 ("mm/huge_memory: do not clobber swp_entry_t during THP split") issues a warning when page_tail->private is found to be non-0 (unless it's swapcache). Change that warning to dump page_tail (which also dumps head), instead of just the head: so far we have seen dead000000000122, dead000000000003, dead000000000001 or 0000000000000002 in the raw output for tail private. We could just delete the warning, but today's consensus appears to want page->private to be 0, unless there's a good reason for it to be set: so now clear it in prep_compound_tail() (more general than just for THP; but not for high order allocation, which makes no pass down the tails).

[PATCH] hugetlb: don't delete vma_lock in hugetlb MADV_DONTNEED processing

by Mike Kravetz

madvise(MADV_DONTNEED) ends up calling zap_page_range() to clear the page tables associated with the address range. For hugetlb vmas, zap_page_range will call __unmap_hugepage_range_final. However, __unmap_hugepage_range_final assumes the passed vma is about to be removed and deletes the vma_lock to prevent pmd sharing as the vma is on the way out. In the case of madvise(MADV_DONTNEED) the vma remains, but the missing vma_lock prevents pmd sharing and could potentially lead to issues with truncation/fault races. This issue was originally reported here [1] as a BUG triggered in page_try_dup_anon_rmap. Prior to the introduction of the hugetlb vma_lock, __unmap_hugepage_range_final cleared the VM_MAYSHARE flag to prevent pmd sharing. Subsequent faults on this vma were confused as VM_MAYSHARE indicates a sharable vma, but was not set so page_mapping was not set in new pages added to the page table. This resulted in pages that appeared anonymous in a VM_SHARED vma and triggered the BUG. Create a new routine clear_hugetlb_page_range() that can be called from madvise(MADV_DONTNEED) for hugetlb vmas. It has the same setup as zap_page_range, but does not delete the vma_lock.

That malloc library may be doing MADV_DONTNEED calls on memory that is no longer needed, expecting those calls to happen on PAGE_SIZE boundaries. However, currently the MADV_DONTNEED code rounds up any such requests to HPAGE_PMD_SIZE boundaries. This leads to undesired outcomes when jemalloc expects a 4kB MADV_DONTNEED, but 2MB of memory get zeroed out, instead. Use of pre-built shared libraries means that user code does not always know the page size of every memory arena in use. Avoid unexpected data loss with MADV_DONTNEED by rounding up only to PAGE_SIZE (in do_madvise), and rounding down to huge page granularity. That way programs will only get as much memory zeroed out as they requested.

[PATCH] counter: 104-quad-8: Fix race getting function mode and direction

by William Breathitt Gray

The quad8_action_read() function checks the Count function mode and Count direction without first acquiring a lock. This is a race condition because the function mode could change by the time the direction is checked. Because the quad8_function_read() already acquires a lock internally, the quad8_function_read() is refactored to spin out the no-lock code to a new quad8_function_get() function. To resolve the race condition in quad8_action_read(), a lock is acquired before calling quad8_function_get() and quad8_direction_read() in order to get both function mode and direction atomically.
