The current nilfs2 sysfs support has issues with the timing of creation and deletion of sysfs entries, potentially leading to null pointer dereferences, use-after-free, and lockdep warnings. Some of the sysfs attributes for nilfs2 per-filesystem instance refer to metadata file "cpfile", "sufile", or "dat", but nilfs_sysfs_create_device_group that creates those attributes is executed before the inodes for these metadata files are loaded, and nilfs_sysfs_delete_device_group which deletes these sysfs entries is called after releasing their metadata file inodes. Therefore, access to some of these sysfs attributes may occur outside of the lifetime of these metadata files, resulting in inode NULL pointer dereferences or use-after-free. In addition, the call to nilfs_sysfs_create_device_group() is made during the locking period of the semaphore "ns_sem" of nilfs object, so the shrinker call caused by the memory allocation for the sysfs entries, may derive lock dependencies "ns_sem" -> (shrinker) -> "locks acquired in nilfs_evict_inode()". Since nilfs2 may acquire "ns_sem" deep in the call stack holding other locks via its error handler __nilfs_error(), this causes lockdep to report circular locking. This is a false positive and no circular locking actually occurs as no inodes exist yet when nilfs_sysfs_create_device_group() is called. Fortunately, the lockdep warnings can be resolved by simply moving the call to nilfs_sysfs_create_device_group() out of "ns_sem". This fixes these sysfs issues by revising where the device's sysfs interface is created/deleted and keeping its lifetime within the lifetime of the metadata files above.

Device exclusive page table entries are used to prevent CPU access to a page whilst it is being accessed from a device. Typically this is used to implement atomic operations when the underlying bus does not support atomic access. When a CPU thread encounters a device exclusive entry it locks the page and restores the original entry after calling mmu notifiers to signal drivers that exclusive access is no longer available. The device exclusive entry holds a reference to the page making it safe to access the struct page whilst the entry is present. However the fault handling code does not hold the PTL when taking the page lock. This means if there are multiple threads faulting concurrently on the device exclusive entry one will remove the entry whilst others will wait on the page lock without holding a reference. This can lead to threads locking or waiting on a folio with a zero refcount. Whilst mmap_lock prevents the pages getting freed via munmap() they may still be freed by a migration. This leads to warnings such as PAGE_FLAGS_CHECK_AT_FREE due to the page being locked when the refcount drops to zero. Fix this by trying to take a reference on the folio before locking it. The code already checks the PTE under the PTL and aborts if the entry is no longer there. It is also possible the folio has been unmapped, freed and re-allocated allowing a reference to be taken on an unrelated folio. This case is also detected by the PTE check and the folio is unlocked without further changes.

Finally I figured out it was caused by a fatal signal. When a process is allocating memory via vm_area_alloc_pages(), it will break directly even if it hasn't allocated the requested pages when it receives a fatal signal. In that case, we shouldn't show this warn_alloc, as it is useless. We only need to show this warning when there're really no enough pages.

The finalization of nilfs_segctor_thread() can race with nilfs_segctor_kill_thread() which terminates that thread, potentially causing a use-after-free BUG as KASAN detected. At the end of nilfs_segctor_thread(), it assigns NULL to "sc_task" member of "struct nilfs_sc_info" to indicate the thread has finished, and then notifies nilfs_segctor_kill_thread() of this using waitqueue "sc_wait_task" on the struct nilfs_sc_info. However, here, immediately after the NULL assignment to "sc_task", it is possible that nilfs_segctor_kill_thread() will detect it and return to continue the deallocation, freeing the nilfs_sc_info structure before the thread does the notification. This fixes the issue by protecting the NULL assignment to "sc_task" and its notification, with spinlock "sc_state_lock" of the struct nilfs_sc_info. Since nilfs_segctor_kill_thread() does a final check to see if "sc_task" is NULL with "sc_state_lock" locked, this can eliminate the race.

This patch fixes an issue that a hugetlb uffd-wr-protected mapping can be writable even with uffd-wp bit set. It only happens with hugetlb private mappings, when someone firstly wr-protects a missing pte (which will install a pte marker), then a write to the same page without any prior access to the page. Userfaultfd-wp trap for hugetlb was implemented in hugetlb_fault() before reaching hugetlb_wp() to avoid taking more locks that userfault won't need. However there's one CoW optimization path that can trigger hugetlb_wp() inside hugetlb_no_page(), which will bypass the trap. This patch skips hugetlb_wp() for CoW and retries the fault if uffd-wp bit is detected. The new path will only trigger in the CoW optimization path because generic hugetlb_fault() (e.g. when a present pte was wr-protected) will resolve the uffd-wp bit already. Also make sure anonymous UNSHARE won't be affected and can still be resolved, IOW only skip CoW not CoR. This patch will be needed for v5.19+ hence copy stable.

Use the maple tree in RCU mode for VMA tracking. The maple tree tracks the stack and is able to update the pivot (lower/upper boundary) in-place to allow the page fault handler to write to the tree while holding just the mmap read lock. This is safe as the writes to the stack have a guard VMA which ensures there will always be a NULL in the direction of the growth and thus will only update a pivot. It is possible, but not recommended, to have VMAs that grow up/down without guard VMAs. syzbot has constructed a testcase which sets up a VMA to grow and consume the empty space. Overwriting the entire NULL entry causes the tree to be altered in a way that is not safe for concurrent readers; the readers may see a node being rewritten or one that does not match the maple state they are using. Enabling RCU mode allows the concurrent readers to see a stable node and will return the expected result.

Dereferencing RCU objects within the RCU callback without the RCU check has caused lockdep to complain. Fix the RCU dereferencing by using the RCU callback lock to ensure the operation is safe. Also stop creating a new lock to use for dereferencing during destruction of the tree or subtree. Instead, pass through a pointer to the tree that has the lock that is held for RCU dereferencing checking. It also does not make sense to use the maple state in the freeing scenario as the tree walk is a special case where the tree no longer has the normal encodings and parent pointers.

During the development of the maple tree, the strategy of freeing multiple nodes changed and, in the process, the pivots were reused to store pointers to dead nodes. To ensure the readers see accurate pivots, the writers need to mark the nodes as dead and call smp_wmb() to ensure any readers can identify the node as dead before using the pivot values. There were two places where the old method of marking the node as dead without smp_wmb() were being used, which resulted in RCU readers seeing the wrong pivot value before seeing the node was dead. Fix this race condition by using mte_set_node_dead() which has the smp_wmb() call to ensure the race is closed. Add a WARN_ON() to the ma_free_rcu() call to ensure all nodes being freed are marked as dead to ensure there are no other call paths besides the two updated paths. This is necessary for the RCU mode of the maple tree. Link: https://lkml.kernel.org/r/20230227173632.3292573-6-surenb@google.com Fixes: 54a611b6 ("Maple Tree: add new data structure") Signed-off-by:

Patch series "Fix VMA tree modification under mmap read lock". Syzbot reported a BUG_ON in mm/mmap.c which was found to be caused by an inconsistency between threads walking the VMA maple tree. The inconsistency is caused by the page fault handler modifying the maple tree while holding the mmap_lock for read. This only happens for stack VMAs. We had thought this was safe as it only modifies a single pivot in the tree. Unfortunately, syzbot constructed a test case where the stack had no guard page and grew the stack to abut the next VMA. This causes us to delete the NULL entry between the two VMAs and rewrite the node. We considered several options for fixing this, including dropping the mmap_lock, then reacquiring it for write; and relaxing the definition of the tree to permit a zero-length NULL entry in the node. We decided the best option was to backport some of the RCU patches from -next, which solve the problem by allocating a new node and RCU-freeing the old node. Since the problem exists in 6.1, we preferred a solution which is similar to the one we intended to merge next merge window. These patches have been in -next since next-20230301, and have received intensive testing in Android as part of the RCU page fault patchset. They were also sent as part of the "Per-VMA locks" v4 patch series. Patches 1 to 7 are bug fixes for RCU mode of the tree and patch 8 enables RCU mode for the tree. Performance v6.3-rc3 vs patched v6.3-rc3: Running these changes through mmtests showed there was a 15-20% performance decrease in will-it-scale/brk1-processes. This tests creating and inserting a single VMA repeatedly through the brk interface and isn't representative of any real world applications. This patch (of 8): ma_pivots() and ma_data_end() may be called with a dead node. Ensure to that the node isn't dead before using the returned values. This is necessary for RCU mode of the maple tree.

The struct pages could be discontiguous when the kfence pool is allocated via alloc_contig_pages() with CONFIG_SPARSEMEM and !CONFIG_SPARSEMEM_VMEMMAP. This may result in setting PG_slab and memcg_data to a arbitrary address (may be not used as a struct page), which in the worst case might corrupt the kernel. So the iteration should use nth_page().

Pull yet more xfs bug fixes from Darrick Wong: "The first bugfix addresses a longstanding problem where we use the wrong file mapping cursors when trying to compute the speculative preallocation quantity. This has been causing sporadic crashes when alwayscow mode is engaged. The other two fixes correct minor problems in more recent changes. - Fix the new allocator tracepoints because git am mismerged the changes such that the trace_XXX got rebased to be in function YYY instead of XXX - Ensure that the perag AGFL_RESET state is consistent with whatever we've just read off the disk - Fix a bug where we used the wrong iext cursor during a write begin" * tag 'xfs-6.3-fixes-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: fix mismerged tracepoints xfs: clear incore AGFL_RESET state if it's not needed xfs: pass the correct cursor to xfs_iomap_prealloc_size -

Pull xfs percpu counter fixes from Darrick Wong: "We discovered a filesystem summary counter corruption problem that was traced to cpu hot-remove racing with the call to percpu_counter_sum that sets the free block count in the superblock when writing it to disk. The root cause is that percpu_counter_sum doesn't cull from dying cpus and hence misses those counter values if the cpu shutdown hooks have not yet run to merge the values. I'm hoping this is a fairly painless fix to the problem, since the dying cpu mask should generally be empty. It's been in for-next for a week without any complaints from the bots. - Fix a race in the percpu counters summation code where the summation failed to add in the values for any CPUs that were dying but not yet dead. This fixes some minor discrepancies and incorrect assertions when running generic/650" * tag 'xfs-6.3-fixes-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: pcpcntr: remove percpu_counter_sum_all() fork: remove use of percpu_counter_sum_all pcpcntrs: fix dying cpu summation race cpumask: introduce for_each_cpu_or -

Pull xfs fixes from Darrick Wong: "This batch started with some debugging enhancements to the new allocator refactoring that we put in 6.3-rc1 to assist developers in rebasing their dev branches. As for more serious code changes -- there's a bug fix to make the lockless allocator scan the whole filesystem before resorting to the locking allocator. We're also adding a selftest for the venerable directory/xattr hash function to make sure that it produces consistent results so that we can address any fallout as soon as possible. - Add a few debugging assertions so that people (me) trying to port code to the new allocator functions don't mess up the caller requirements - Relax some overly cautious lock ordering enforcement in the new allocator code, which means that file allocations will locklessly scan for the best space they can get before backing off to the traditional lock-and-really-get-it behavior - Add tracepoints to make it easier to trace the xfs allocator behavior - Actually test the dir/xattr hash algorithm to make sure it produces consistent results across all the platforms XFS supports" * tag 'xfs-6.3-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: test dir/attr hash when loading module xfs: add tracepoints for each of the externally visible allocators xfs: walk all AGs if TRYLOCK passed to xfs_alloc_vextent_iterate_ags xfs: try to idiot-proof the allocators -
