[PATCH v4 1/2] staging: iio: frequency: ad9832: Use SLEEP bit instead of RESET to disable output

by Gabriel Shahrouzi

According to the AD9832 datasheet (Table 10, D12 description), setting the RESET bit forces the phase accumulator to zero, which corresponds to a full-scale DC output, rather than disabling the output signal. The correct way to disable the output and enter a low-power state is to set the AD9832_SLEEP bit (Table 10, D13 description), which powers down the internal DAC current sources and disables internal clocks.

So, the tests that are part of your (Intel) accel-config package are the only convenient way that I’ve found to do so. It is also convenient, there is a “make check” target in the top Makefile that will invoke both set of DMA tests, and some crypto (IAA) tests. I have been planning to give this to our QA group as a verification suite. Do you have an alternative to this? This should be the right test package. Let me talk to our QA people and see if there are any issues. We can resolve this off list. If there's any issues that end up pointing to the original bug, we can raise that then.

+ mm-userfaultfd-fix-uninitialized-output-field-for-eagain-race.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm/userfaultfd: fix uninitialized output field for -EAGAIN race has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-userfaultfd-fix-uninitialized-output-field-for-eagain-race.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-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm 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: Peter Xu <peterx(a)redhat.com> Subject: mm/userfaultfd: fix uninitialized output field for -EAGAIN race Date: Thu, 24 Apr 2025 17:57:28 -0400 While discussing some userfaultfd relevant issues recently, Andrea noticed a potential ABI breakage with -EAGAIN on almost all userfaultfd ioctl()s. Quote from Andrea, explaining how -EAGAIN was processed, and how this should fix it (taking example of UFFDIO_COPY ioctl): The "mmap_changing" and "stale pmd" conditions are already reported as -EAGAIN written in the copy field, this does not change it. This change removes the subnormal case that left copy.copy uninitialized and required apps to explicitly set the copy field to get deterministic behavior (which is a requirement contrary to the documentation in both the manpage and source code). In turn there's no alteration to backwards compatibility as result of this change because userland will find the copy field consistently set to -EAGAIN, and not anymore sometime -EAGAIN and sometime uninitialized. Even then the change only can make a difference to non cooperative users of userfaultfd, so when UFFD_FEATURE_EVENT_* is enabled, which is not true for the vast majority of apps using userfaultfd or this unintended uninitialized field may have been noticed sooner. Meanwhile, since this bug existed for years, it also almost affects all ioctl()s that was introduced later. Besides UFFDIO_ZEROPAGE, these also get affected in the same way: - UFFDIO_CONTINUE - UFFDIO_POISON - UFFDIO_MOVE This patch should have fixed all of them.

[PATCH stable] xdp: Reset bpf_redirect_info before running a xdp's BPF prog.

by Sebastian Andrzej Siewior

Ricardo reported a KASAN discovered use after free in v6.6-stable. The syzbot starts a BPF program via xdp_test_run_batch() which assigns ri->tgt_value via dev_hash_map_redirect() and the return code isn't XDP_REDIRECT it looks like nonsense. So the output in bpf_warn_invalid_xdp_action() appears once. Then the TUN driver runs another BPF program (on the same CPU) which returns XDP_REDIRECT without setting ri->tgt_value first. It invokes bpf_trace_printk() to print four characters and obtain the required return value. This is enough to get xdp_do_redirect() invoked which then accesses the pointer in tgt_value which might have been already deallocated. This problem does not affect upstream because since commit 401cb7dae8130 ("net: Reference bpf_redirect_info via task_struct on PREEMPT_RT.") the per-CPU variable is referenced via task's task_struct and exists on the stack during NAPI callback. Therefore it is cleared once before the first invocation and remains valid within the RCU section of the NAPI callback. Instead of performing the huge backport of the commit (plus its fix ups) here is an alternative version which only resets the variable in question prior invoking the BPF program.

Like I said, it got no messages booting up, all looked fine. But when running the actual test suite in the accel-config tarball specifically the iaa crypt tests, they failed and the dmesg was from vfio_pci_core failed to load with an unknown symbol. I'm not sure what the test consists of (haven't worked on this device for almost 2 years). But usually the device is either bound to the idxd driver or the vfio_pci driver. Not both. And if the idxd driver didn't emit any errors while loading, then the test failure may be something else... Another way to verify is to set CONFIG_IOMMU_DEFAULT_DMA_LAZY vs PASSTHROUGH. If the tests still fail then it's something else.

[alternative-merged] smaps-fix-crash-in-smaps_hugetlb_range-for-non-present-hugetlb-entries.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: smaps: fix crash in smaps_hugetlb_range for non-present hugetlb entries has been removed from the -mm tree. Its filename was smaps-fix-crash-in-smaps_hugetlb_range-for-non-present-hugetlb-entries.patch This patch was dropped because an alternative patch was or shall be merged ------------------------------------------------------ From: Ming Wang <wangming01(a)loongson.cn> Subject: smaps: fix crash in smaps_hugetlb_range for non-present hugetlb entries Date: Wed, 23 Apr 2025 09:03:59 +0800 When reading /proc/pid/smaps for a process that has mapped a hugetlbfs file with MAP_PRIVATE, the kernel might crash inside pfn_swap_entry_to_page. This occurs on LoongArch under specific conditions. The root cause involves several steps: 1. When the hugetlbfs file is mapped (MAP_PRIVATE), the initial PMD (or relevant level) entry is often populated by the kernel during mmap() with a non-present entry pointing to the architecture's invalid_pte_table On the affected LoongArch system, this address was observed to be 0x90000000031e4000. 2. The smaps walker (walk_hugetlb_range -> smaps_hugetlb_range) reads this entry. 3. The generic is_swap_pte() macro checks `!pte_present() && !pte_none()`. The entry (invalid_pte_table address) is not present. Crucially, the generic pte_none() check (`!(pte_val(pte) & ~_PAGE_GLOBAL)`) returns false because the invalid_pte_table address is non-zero. Therefore, is_swap_pte() incorrectly returns true. 4. The code enters the `else if (is_swap_pte(...))` block. 5. Inside this block, it checks `is_pfn_swap_entry()`. Due to a bit pattern coincidence in the invalid_pte_table address on LoongArch, the embedded generic `is_migration_entry()` check happens to return true (misinterpreting parts of the address as a migration type). 6. This leads to a call to pfn_swap_entry_to_page() with the bogus swap entry derived from the invalid table address. 7. pfn_swap_entry_to_page() extracts a meaningless PFN, finds an unrelated struct page, checks its lock status (unlocked), and hits the `BUG_ON(is_migration_entry(entry) && !PageLocked(p))` assertion. The original code's intent in the `else if` block seems aimed at handling potential migration entries, as indicated by the inner `is_pfn_swap_entry()` check. The issue arises because the outer `is_swap_pte()` check incorrectly includes the invalid table pointer case on LoongArch. This patch fixes the issue by changing the condition in smaps_hugetlb_range() from the broad `is_swap_pte()` to the specific `is_hugetlb_entry_migration()`. The `is_hugetlb_entry_migration()` helper function correctly handles this by first checking `huge_pte_none()`. Architectures like LoongArch can provide an override for `huge_pte_none()` that specifically recognizes the `invalid_pte_table` address as a "none" state for HugeTLB entries. This ensures `is_hugetlb_entry_migration()` returns false for the invalid entry, preventing the code from entering the faulty block. This change makes the code reflect the likely original intent (handling migration) more accurately and leverages architecture-specific helpers (`huge_pte_none`) to correctly interpret special PTE/PMD values in the HugeTLB context, fixing the crash on LoongArch without altering the generic is_swap_pte() behavior.
