James Houghton	aff80fb99b	mm: teach mincore_hugetlb about pte markers ... commit 63cf584203f3367c8b073d417c8e5cbbfc450506 upstream. By checking huge_pte_none(), we incorrectly classify PTE markers as "present". Instead, check huge_pte_none_mostly(), classifying PTE markers the same as if the PTE were completely blank. PTE markers, unlike other kinds of swap entries, don't reference any physical page and don't indicate that a physical page was mapped previously. As such, treat them as non-present for the sake of mincore().

David Hildenbrand	b8388048b5	mm/userfaultfd: propagate uffd-wp bit when PTE-mapping the huge zeropage ... commit 42b2af2c9b7eede8ef21d0943f84d135e21a32a3 upstream. Currently, we'd lose the userfaultfd-wp marker when PTE-mapping a huge zeropage, resulting in the next write faults in the PMD range not triggering uffd-wp events. Various actions (partial MADV_DONTNEED, partial mremap, partial munmap, partial mprotect) could trigger this. However, most importantly, un-protecting a single sub-page from the userfaultfd-wp handler when processing a uffd-wp event will PTE-map the shared huge zeropage and lose the uffd-wp bit for the remainder of the PMD. Let's properly propagate the uffd-wp bit to the PMDs. #define _GNU_SOURCE #include <stdio.h> #include <stdlib.h> #include <stdint.h> #include <stdbool.h> #include <inttypes.h> #include <fcntl.h> #include <unistd.h> #include <errno.h> #include <poll.h> #include <pthread.h> #include <sys/mman.h> #include <sys/syscall.h> #include <sys/ioctl.h> #include <linux/userfaultfd.h> static size_t pagesize; static int uffd; static volatile bool uffd_triggered; #define barrier() __asm__ __volatile__("": : :"memory") static void uffd_wp_range(char *start, size_t size, bool wp) { struct uffdio_writeprotect uffd_writeprotect; uffd_writeprotect.range.start = (unsigned long) start; uffd_writeprotect.range.len = size; if (wp) { uffd_writeprotect.mode = UFFDIO_WRITEPROTECT_MODE_WP; } else { uffd_writeprotect.mode = 0; } if (ioctl(uffd, UFFDIO_WRITEPROTECT, &uffd_writeprotect)) { fprintf(stderr, "UFFDIO_WRITEPROTECT failed: %d\n", errno); exit(1); } } static void *uffd_thread_fn(void *arg) { static struct uffd_msg msg; ssize_t nread; while (1) { struct pollfd pollfd; int nready; pollfd.fd = uffd; pollfd.events = POLLIN; nready = poll(&pollfd, 1, -1); if (nready == -1) { fprintf(stderr, "poll() failed: %d\n", errno); exit(1); } nread = read(uffd, &msg, sizeof(msg)); if (nread <= 0) continue; if (msg.event != UFFD_EVENT_PAGEFAULT || !(msg.arg.pagefault.flags & UFFD_PAGEFAULT_FLAG_WP)) { printf("FAIL: wrong uffd-wp event fired\n"); exit(1); } /* un-protect the single page. */ uffd_triggered = true; uffd_wp_range((char *)(uintptr_t)msg.arg.pagefault.address, pagesize, false); } return arg; } static int setup_uffd(char *map, size_t size) { struct uffdio_api uffdio_api; struct uffdio_register uffdio_register; pthread_t thread; uffd = syscall(__NR_userfaultfd, O_CLOEXEC | O_NONBLOCK | UFFD_USER_MODE_ONLY); if (uffd < 0) { fprintf(stderr, "syscall() failed: %d\n", errno); return -errno; } uffdio_api.api = UFFD_API; uffdio_api.features = UFFD_FEATURE_PAGEFAULT_FLAG_WP; if (ioctl(uffd, UFFDIO_API, &uffdio_api) < 0) { fprintf(stderr, "UFFDIO_API failed: %d\n", errno); return -errno; } if (!(uffdio_api.features & UFFD_FEATURE_PAGEFAULT_FLAG_WP)) { fprintf(stderr, "UFFD_FEATURE_WRITEPROTECT missing\n"); return -ENOSYS; } uffdio_register.range.start = (unsigned long) map; uffdio_register.range.len = size; uffdio_register.mode = UFFDIO_REGISTER_MODE_WP; if (ioctl(uffd, UFFDIO_REGISTER, &uffdio_register) < 0) { fprintf(stderr, "UFFDIO_REGISTER failed: %d\n", errno); return -errno; } pthread_create(&thread, NULL, uffd_thread_fn, NULL); return 0; } int main(void) { const size_t size = 4 * 1024 * 1024ull; char *map, *cur; pagesize = getpagesize(); map = mmap(NULL, size, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0); if (map == MAP_FAILED) { fprintf(stderr, "mmap() failed\n"); return -errno; } if (madvise(map, size, MADV_HUGEPAGE)) { fprintf(stderr, "MADV_HUGEPAGE failed\n"); return -errno; } if (setup_uffd(map, size)) return 1; /* Read the whole range, populating zeropages. */ madvise(map, size, MADV_POPULATE_READ); /* Write-protect the whole range. */ uffd_wp_range(map, size, true); /* Make sure uffd-wp triggers on each page. */ for (cur = map; cur < map + size; cur += pagesize) { uffd_triggered = false; barrier(); /* Trigger a write fault. */ *cur = 1; barrier(); if (!uffd_triggered) { printf("FAIL: uffd-wp did not trigger\n"); return 1; } } printf("PASS: uffd-wp triggered\n"); return 0; } Link: https://lkml.kernel.org/r/20230302175423.589164-1-david@redhat.com Fixes: e06f1e1dd499 ("userfaultfd: wp: enabled write protection in userfaultfd API") Signed-off-by: David Hildenbrand <david@redhat.com> Acked-by: Peter Xu <peterx@redhat.com> Cc: Mike Rapoport <rppt@linux.vnet.ibm.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Jerome Glisse <jglisse@redhat.com> Cc: Shaohua Li <shli@fb.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2023-03-22 13:34:03 +01:00

Tong Tiangen	313b18c774	memory tier: release the new_memtier in find_create_memory_tier() ... commit 93419139fa14124c1c507d804f2b28866ebee28d upstream. In find_create_memory_tier(), if failed to register device, then we should release new_memtier from the tier list and put device instead of memtier.

Yin Fengwei	71946389a7	mm/thp: check and bail out if page in deferred queue already ... commit 81e506bec9be1eceaf5a2c654e28ba5176ef48d8 upstream. Kernel build regression with LLVM was reported here: https://lore.kernel.org/all/Y1GCYXGtEVZbcv%2F5@dev-arch.thelio-3990X/ with commit f35b5d7d676e ("mm: align larger anonymous mappings on THP boundaries"). And the commit f35b5d7d676e was reverted. It turned out the regression is related with madvise(MADV_DONTNEED) was used by ld.lld. But with none PMD_SIZE aligned parameter len. trace-bpfcc captured: 531607 531732 ld.lld do_madvise.part.0 start: 0x7feca9000000, len: 0x7fb000, behavior: 0x4 531607 531793 ld.lld do_madvise.part.0 start: 0x7fec86a00000, len: 0x7fb000, behavior: 0x4 If the underneath physical page is THP, the madvise(MADV_DONTNEED) can trigger split_queue_lock contention raised significantly. perf showed following data: 14.85% 0.00% ld.lld [kernel.kallsyms] [k] entry_SYSCALL_64_after_hwframe 11.52% entry_SYSCALL_64_after_hwframe do_syscall_64 __x64_sys_madvise do_madvise.part.0 zap_page_range unmap_single_vma unmap_page_range page_remove_rmap deferred_split_huge_page __lock_text_start native_queued_spin_lock_slowpath If THP can't be removed from rmap as whole THP, partial THP will be removed from rmap by removing sub-pages from rmap. Even the THP head page is added to deferred queue already, the split_queue_lock will be acquired and check whether the THP head page is in the queue already. Thus, the contention of split_queue_lock is raised. Before acquire split_queue_lock, check and bail out early if the THP head page is in the queue already. The checking without holding split_queue_lock could race with deferred_split_scan, but it doesn't impact the correctness here.

Johannes Weiner	f65d6ee1d1	mm: memcontrol: deprecate charge moving ... commit da34a8484d162585e22ed8c1e4114aa2f60e3567 upstream. Charge moving mode in cgroup1 allows memory to follow tasks as they migrate between cgroups. This is, and always has been, a questionable thing to do - for several reasons. First, it's expensive. Pages need to be identified, locked and isolated from various MM operations, and reassigned, one by one. Second, it's unreliable. Once pages are charged to a cgroup, there isn't always a clear owner task anymore. Cache isn't moved at all, for example. Mapped memory is moved - but if trylocking or isolating a page fails, it's arbitrarily left behind. Frequent moving between domains may leave a task's memory scattered all over the place. Third, it isn't really needed. Launcher tasks can kick off workload tasks directly in their target cgroup. Using dedicated per-workload groups allows fine-grained policy adjustments - no need to move tasks and their physical pages between control domains. The feature was never forward-ported to cgroup2, and it hasn't been missed. Despite it being a niche usecase, the maintenance overhead of supporting it is enormous. Because pages are moved while they are live and subject to various MM operations, the synchronization rules are complicated. There are lock_page_memcg() in MM and FS code, which non-cgroup people don't understand. In some cases we've been able to shift code and cgroup API calls around such that we can rely on native locking as much as possible. But that's fragile, and sometimes we need to hold MM locks for longer than we otherwise would (pte lock e.g.). Mark the feature deprecated. Hopefully we can remove it soon. And backport into -stable kernels so that people who develop against earlier kernels are warned about this deprecation as early as possible.

Naoya Horiguchi	deab8114fb	mm/hwpoison: convert TTU_IGNORE_HWPOISON to TTU_HWPOISON ... commit 6da6b1d4a7df8c35770186b53ef65d388398e139 upstream. After a memory error happens on a clean folio, a process unexpectedly receives SIGBUS when it accesses the error page. This SIGBUS killing is pointless and simply degrades the level of RAS of the system, because the clean folio can be dropped without any data lost on memory error handling as we do for a clean pagecache. When memory_failure() is called on a clean folio, try_to_unmap() is called twice (one from split_huge_page() and one from hwpoison_user_mappings()). The root cause of the issue is that pte conversion to hwpoisoned entry is now done in the first call of try_to_unmap() because PageHWPoison is already set at this point, while it's actually expected to be done in the second call. This behavior disturbs the error handling operation like removing pagecache, which results in the malfunction described above. So convert TTU_IGNORE_HWPOISON into TTU_HWPOISON and set TTU_HWPOISON only when we really intend to convert pte to hwpoison entry. This can prevent other callers of try_to_unmap() from accidentally converting to hwpoison entries.

Peter Xu	54806cb751	mm/migrate: fix wrongly apply write bit after mkdirty on sparc64 ... commit 96a9c287e25d690fd9623b5133703b8e310fbed1 upstream. Nick Bowler reported another sparc64 breakage after the young/dirty persistent work for page migration (per "Link:" below). That's after a similar report [2]. It turns out page migration was overlooked, and it wasn't failing before because page migration was not enabled in the initial report test environment. David proposed another way [2] to fix this from sparc64 side, but that patch didn't land somehow. Neither did I check whether there's any other arch that has similar issues. Let's fix it for now as simple as moving the write bit handling to be after dirty, like what we did before. Note: this is based on mm-unstable, because the breakage was since 6.1 and we're at a very late stage of 6.2 (-rc8), so I assume for this specific case we should target this at 6.3.

I was running traces of the read code against an RAID storage system to understand why read requests were being misaligned against the underlying RAID strips. I found that the page end offset calculation in filemap_get_read_batch() was off by one. When a read is submitted with end offset 1048575, then it calculates the end page for read of 256 when it should be 255. "last_index" is the index of the page beyond the end of the read and it should be skipped when get a batch of pages for read in @filemap_get_read_batch(). The below simple patch fixes the problem.

Zach O'Keefe	fd71c8d3b0	mm/MADV_COLLAPSE: set EAGAIN on unexpected page refcount ... commit ae63c898f4004bbc7d212f4adcb3bb14852c30d6 upstream. During collapse, in a few places we check to see if a given small page has any unaccounted references. If the refcount on the page doesn't match our expectations, it must be there is an unknown user concurrently interested in the page, and so it's not safe to move the contents elsewhere. However, the unaccounted pins are likely an ephemeral state. In this situation, MADV_COLLAPSE returns -EINVAL when it should return -EAGAIN. This could cause userspace to conclude that the syscall failed, when it in fact could succeed by retrying.

Qi Zheng	86e3baf6a6	mm: shrinkers: fix deadlock in shrinker debugfs ... commit badc28d4924bfed73efc93f716a0c3aa3afbdf6f upstream. The debugfs_remove_recursive() is invoked by unregister_shrinker(), which is holding the write lock of shrinker_rwsem. It will waits for the handler of debugfs file complete. The handler also needs to hold the read lock of shrinker_rwsem to do something. So it may cause the following deadlock: CPU0 CPU1 debugfs_file_get() shrinker_debugfs_count_show()/shrinker_debugfs_scan_write() unregister_shrinker() --> down_write(&shrinker_rwsem); debugfs_remove_recursive() // wait for (A) --> wait_for_completion(); // wait for (B) --> down_read_killable(&shrinker_rwsem) debugfs_file_put() -- (A) up_write() -- (B) The down_read_killable() can be killed, so that the above deadlock can be recovered. But it still requires an extra kill action, otherwise it will block all subsequent shrinker-related operations, so it's better to fix it.

Sometimes, it would also show up as corruption in the free list pointer and cause crashes. After bisecting the issue, we found the issue started from commit e320d3012d25 ("mm/page_alloc.c: fix freeing non-compound pages"): if (put_page_testzero(page)) free_the_page(page, order); else if (!PageHead(page)) while (order-- > 0) free_the_page(page + (1 << order), order); So the problem is the check PageHead is racy because at this point we already dropped our reference to the page. So even if we came in with compound page, the page can already be freed and PageHead can return false and we will end up freeing all the tail pages causing double free.

Mike Kravetz	d8b46cc1cf	migrate: hugetlb: check for hugetlb shared PMD in node migration ... commit 73bdf65ea74857d7fb2ec3067a3cec0e261b1462 upstream. migrate_pages/mempolicy semantics state that CAP_SYS_NICE is required to move pages shared with another process to a different node. page_mapcount > 1 is being used to determine if a hugetlb page is shared. However, a hugetlb page will have a mapcount of 1 if mapped by multiple processes via a shared PMD. As a result, hugetlb pages shared by multiple processes and mapped with a shared PMD can be moved by a process without CAP_SYS_NICE. To fix, check for a shared PMD if mapcount is 1. If a shared PMD is found consider the page shared.

Zach O'Keefe	96aaaf8666	mm/MADV_COLLAPSE: catch !none !huge !bad pmd lookups ... commit edb5d0cf5525357652aff6eacd9850b8ced07143 upstream. In commit 34488399fa08 ("mm/madvise: add file and shmem support to MADV_COLLAPSE") we make the following change to find_pmd_or_thp_or_none(): - if (!pmd_present(pmde)) - return SCAN_PMD_NULL; + if (pmd_none(pmde)) + return SCAN_PMD_NONE; This was for-use by MADV_COLLAPSE file/shmem codepaths, where MADV_COLLAPSE might identify a pte-mapped hugepage, only to have khugepaged race-in, free the pte table, and clear the pmd. Such codepaths include: A) If we find a suitably-aligned compound page of order HPAGE_PMD_ORDER already in the pagecache. B) In retract_page_tables(), if we fail to grab mmap_lock for the target mm/address. In these cases, collapse_pte_mapped_thp() really does expect a none (not just !present) pmd, and we want to suitably identify that case separate from the case where no pmd is found, or it's a bad-pmd (of course, many things could happen once we drop mmap_lock, and the pmd could plausibly undergo multiple transitions due to intervening fault, split, etc). Regardless, the code is prepared install a huge-pmd only when the existing pmd entry is either a genuine pte-table-mapping-pmd, or the none-pmd. However, the commit introduces a logical hole; namely, that we've allowed !none- && !huge- && !bad-pmds to be classified as genuine pte-table-mapping-pmds. One such example that could leak through are swap entries. The pmd values aren't checked again before use in pte_offset_map_lock(), which is expecting nothing less than a genuine pte-table-mapping-pmd. We want to put back the !pmd_present() check (below the pmd_none() check), but need to be careful to deal with subtleties in pmd transitions and treatments by various arch. The issue is that __split_huge_pmd_locked() temporarily clears the present bit (or otherwise marks the entry as invalid), but pmd_present() and pmd_trans_huge() still need to return true while the pmd is in this transitory state. For example, x86's pmd_present() also checks the _PAGE_PSE , riscv's version also checks the _PAGE_LEAF bit, and arm64 also checks a PMD_PRESENT_INVALID bit. Covering all 4 cases for x86 (all checks done on the same pmd value): 1) pmd_present() && pmd_trans_huge() All we actually know here is that the PSE bit is set. Either: a) We aren't racing with __split_huge_page(), and PRESENT or PROTNONE is set. => huge-pmd b) We are currently racing with __split_huge_page(). The danger here is that we proceed as-if we have a huge-pmd, but really we are looking at a pte-mapping-pmd. So, what is the risk of this danger? The only relevant path is: madvise_collapse() -> collapse_pte_mapped_thp() Where we might just incorrectly report back "success", when really the memory isn't pmd-backed. This is fine, since split could happen immediately after (actually) successful madvise_collapse(). So, it should be safe to just assume huge-pmd here. 2) pmd_present() && !pmd_trans_huge() Either: a) PSE not set and either PRESENT or PROTNONE is. => pte-table-mapping pmd (or PROT_NONE) b) devmap. This routine can be called immediately after unlocking/locking mmap_lock -- or called with no locks held (see khugepaged_scan_mm_slot()), so previous VMA checks have since been invalidated. 3) !pmd_present() && pmd_trans_huge() Not possible. 4) !pmd_present() && !pmd_trans_huge() Neither PRESENT nor PROTNONE set => not present I've checked all archs that implement pmd_trans_huge() (arm64, riscv, powerpc, longarch, x86, mips, s390) and this logic roughly translates (though devmap treatment is unique to x86 and powerpc, and (3) doesn't necessarily hold in general -- but that doesn't matter since !pmd_present() always takes failure path). Also, add a comment above find_pmd_or_thp_or_none() to help future travelers reason about the validity of the code; namely, the possible mutations that might happen out from under us, depending on how mmap_lock is held (if at all).

Vlastimil Babka	97f17a7372	mm, mremap: fix mremap() expanding for vma's with vm_ops->close() ... commit d014cd7c1c358edc3ea82ebf327a036a42ed0164 upstream. Fabian has reported another regression in 6.1 due to ca3d76b0aa80 ("mm: add merging after mremap resize"). The problem is that vma_merge() can fail when vma has a vm_ops->close() method, causing is_mergeable_vma() test to be negative. This was happening for vma mapping a file from fuse-overlayfs, which does have the method. But when we are simply expanding the vma, we never remove it due to the "merge" with the added area, so the test should not prevent the expansion. As a quick fix, check for such vmas and expand them using vma_adjust() directly as was done before commit ca3d76b0aa80. For a more robust long term solution we should try to limit the check for vma_ops->close only to cases that actually result in vma removal, so that no merge would be prevented unnecessarily.

Jann Horn	acb08187b5	mm/khugepaged: fix ->anon_vma race ... commit 023f47a8250c6bdb4aebe744db4bf7f73414028b upstream. If an ->anon_vma is attached to the VMA, collapse_and_free_pmd() requires it to be locked. Page table traversal is allowed under any one of the mmap lock, the anon_vma lock (if the VMA is associated with an anon_vma), and the mapping lock (if the VMA is associated with a mapping); and so to be able to remove page tables, we must hold all three of them. retract_page_tables() bails out if an ->anon_vma is attached, but does this check before holding the mmap lock (as the comment above the check explains). If we racily merged an existing ->anon_vma (shared with a child process) from a neighboring VMA, subsequent rmap traversals on pages belonging to the child will be able to see the page tables that we are concurrently removing while assuming that nothing else can access them. Repeat the ->anon_vma check once we hold the mmap lock to ensure that there really is no concurrent page table access. Hitting this bug causes a lockdep warning in collapse_and_free_pmd(), in the line "lockdep_assert_held_write(&vma->anon_vma->root->rwsem)". It can also lead to use-after-free access.

Longlong Xia	49178d4d61	mm/swapfile: add cond_resched() in get_swap_pages() ... commit 7717fc1a12f88701573f9ed897cc4f6699c661e3 upstream. The softlockup still occurs in get_swap_pages() under memory pressure. 64 CPU cores, 64GB memory, and 28 zram devices, the disksize of each zram device is 50MB with same priority as si. Use the stress-ng tool to increase memory pressure, causing the system to oom frequently. The plist_for_each_entry_safe() loops in get_swap_pages() could reach tens of thousands of times to find available space (extreme case: cond_resched() is not called in scan_swap_map_slots()). Let's add cond_resched() into get_swap_pages() when failed to find available space to avoid softlockup.

Peter Xu	2d11727655	mm/uffd: fix pte marker when fork() without fork event ... commit 49d6d7fb631345b0f2957a7c4be24ad63903150f upstream. Patch series "mm: Fixes on pte markers". Patch 1 resolves the syzkiller report from Pengfei. Patch 2 further harden pte markers when used with the recent swapin error markers. The major case is we should persist a swapin error marker after fork(), so child shouldn't read a corrupted page. This patch (of 2): When fork(), dst_vma is not guaranteed to have VM_UFFD_WP even if src may have it and has pte marker installed. The warning is improper along with the comment. The right thing is to inherit the pte marker when needed, or keep the dst pte empty. A vague guess is this happened by an accident when there's the prior patch to introduce src/dst vma into this helper during the uffd-wp feature got developed and I probably messed up in the rebase, since if we replace dst_vma with src_vma the warning & comment it all makes sense too. Hugetlb did exactly the right here (copy_hugetlb_page_range()). Fix the general path.

[ Upstream commit de4eda9de2d957ef2d6a8365a01e26a435e958cb ] READ/WRITE proved to be actively confusing - the meanings are "data destination, as used with read(2)" and "data source, as used with write(2)", but people keep interpreting those as "we read data from it" and "we write data to it", i.e. exactly the wrong way. Call them ITER_DEST and ITER_SOURCE - at least that is harder to misinterpret...

Vlastimil Babka	e1275a6b2d	Revert "mm/compaction: fix set skip in fast_find_migrateblock" ... commit 95e7a450b8190673675836bfef236262ceff084a upstream. This reverts commit 7efc3b7261030da79001c00d92bc3392fd6c664c. We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged stalling CPU for long periods of time. Investigation of tracepoint data shows that compaction is stuck in repeating fast_find_migrateblock() based migrate page isolation, and then fails to migrate all isolated pages. Commit 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock") was suspected as it was merged in 6.1 and in theory can indeed remove a termination condition for fast_find_migrateblock() under certain conditions, as it removes a place that always marks a scanned pageblock from being re-scanned. There are other such places, but those can be skipped under certain conditions, which seems to match the tracepoint data. Testing of revert also appears to have resolved the issue, thus revert the commit until a more robust solution for the original problem is developed. It's also likely this will fix qemu stalls with 6.1 kernel reported in Link 2, but that is not yet confirmed.

Andrey Konovalov	9f7f5a25f3	FROMLIST: kasan: reset page tags properly with sampling ... [The patch is in the mm-unstable tree.] The implementation of page_alloc poisoning sampling assumed that tag_clear_highpage resets page tags for __GFP_ZEROTAGS allocations. However, this is no longer the case since commit 70c248aca9e7 ("mm: kasan: Skip unpoisoning of user pages"). This leads to kernel crashes when MTE-enabled userspace mappings are used with Hardware Tag-Based KASAN enabled. Reset page tags for __GFP_ZEROTAGS allocations in post_alloc_hook().

Andrey Konovalov	5b43ea3757	FROMGIT: kasan: allow sampling page_alloc allocations for HW_TAGS ... [The patch is in mm-stable tree.] As Hardware Tag-Based KASAN is intended to be used in production, its performance impact is crucial. As page_alloc allocations tend to be big, tagging and checking all such allocations can introduce a significant slowdown. Add two new boot parameters that allow to alleviate that slowdown: - kasan.page_alloc.sample, which makes Hardware Tag-Based KASAN tag only every Nth page_alloc allocation with the order configured by the second added parameter (default: tag every such allocation). - kasan.page_alloc.sample.order, which makes sampling enabled by the first parameter only affect page_alloc allocations with the order equal or greater than the specified value (default: 3, see below). The exact performance improvement caused by using the new parameters depends on their values and the applied workload. The chosen default value for kasan.page_alloc.sample.order is 3, which matches both PAGE_ALLOC_COSTLY_ORDER and SKB_FRAG_PAGE_ORDER. This is done for two reasons: 1. PAGE_ALLOC_COSTLY_ORDER is "the order at which allocations are deemed costly to service", which corresponds to the idea that only large and thus costly allocations are supposed to sampled. 2. One of the workloads targeted by this patch is a benchmark that sends a large amount of data over a local loopback connection. Most multi-page data allocations in the networking subsystem have the order of SKB_FRAG_PAGE_ORDER (or PAGE_ALLOC_COSTLY_ORDER). When running a local loopback test on a testing MTE-enabled device in sync mode, enabling Hardware Tag-Based KASAN introduces a ~50% slowdown. Applying this patch and setting kasan.page_alloc.sampling to a value higher than 1 allows to lower the slowdown. The performance improvement saturates around the sampling interval value of 10 with the default sampling page order of 3. This lowers the slowdown to ~20%. The slowdown in real scenarios involving the network will likely be better. Enabling page_alloc sampling has a downside: KASAN misses bad accesses to a page_alloc allocation that has not been tagged. This lowers the value of KASAN as a security mitigation. However, based on measuring the number of page_alloc allocations of different orders during boot in a test build, sampling with the default kasan.page_alloc.sample.order value affects only ~7% of allocations. The rest ~93% of allocations are still checked deterministically.

Zach O'Keefe	f2f52dd4f5	mm/MADV_COLLAPSE: don't expand collapse when vm_end is past requested end ... commit 52dc031088f00e323140ece4004e70c33153c6dd upstream. MADV_COLLAPSE acts on one hugepage-aligned/sized region at a time, until it has collapsed all eligible memory contained within the bounds supplied by the user. At the top of each hugepage iteration we (re)lock mmap_lock and (re)validate the VMA for eligibility and update variables that might have changed while mmap_lock was dropped. One thing that might occur is that the VMA could be resized, and as such, we refetch vma->vm_end to make sure we don't collapse past the end of the VMA's new end. However, it's possible that when refetching vma->vm_end that we expand the region acted on by MADV_COLLAPSE if vma->vm_end is greater than size+len supplied by the user. The consequence here is that we may attempt to collapse more memory than requested, possibly yielding either "too much success" or "false failure" user-visible results. An example of the former is if we MADV_COLLAPSE the first 4MiB of a 2TiB mmap()'d file, the incorrect refetch would cause the operation to block for much longer than anticipated as we attempt to collapse the entire TiB region. An example of the latter is that applying MADV_COLLPSE to a 4MiB file mapped to the start of a 6MiB VMA will successfully collapse the first 4MiB, then incorrectly attempt to collapse the last hugepage-aligned/sized region -- fail (since readahead/page cache lookup will fail) -- and report a failure to the user. I don't believe there is a kernel stability concern here as we always (re)validate the VMA / region accordingly. Also as Hugh mentions, the user-visible effects are: we try to collapse more memory than requested by the user, and/or failing an operation that should have otherwise succeeded. An example is trying to collapse a 4MiB file contained within a 12MiB VMA. Don't expand the acted-on region when refetching vma->vm_end.

David Hildenbrand	bcde505af1	mm/userfaultfd: enable writenotify while userfaultfd-wp is enabled for a VMA ... commit 51d3d5eb74ff53b92dcff48b30ae2ed8edd85a32 upstream. Currently, we don't enable writenotify when enabling userfaultfd-wp on a shared writable mapping (for now only shmem and hugetlb). The consequence is that vma->vm_page_prot will still include write permissions, to be set as default for all PTEs that get remapped (e.g., mprotect(), NUMA hinting, page migration, ...). So far, vma->vm_page_prot is assumed to be a safe default, meaning that we only add permissions (e.g., mkwrite) but not remove permissions (e.g., wrprotect). For example, when enabling softdirty tracking, we enable writenotify. With uffd-wp on shared mappings, that changed. More details on vma->vm_page_prot semantics were summarized in [1]. This is problematic for uffd-wp: we'd have to manually check for a uffd-wp PTEs/PMDs and manually write-protect PTEs/PMDs, which is error prone. Prone to such issues is any code that uses vma->vm_page_prot to set PTE permissions: primarily pte_modify() and mk_pte(). Instead, let's enable writenotify such that PTEs/PMDs/... will be mapped write-protected as default and we will only allow selected PTEs that are definitely safe to be mapped without write-protection (see can_change_pte_writable()) to be writable. In the future, we might want to enable write-bit recovery -- e.g., can_change_pte_writable() -- at more locations, for example, also when removing uffd-wp protection. This fixes two known cases: (a) remove_migration_pte() mapping uffd-wp'ed PTEs writable, resulting in uffd-wp not triggering on write access. (b) do_numa_page() / do_huge_pmd_numa_page() mapping uffd-wp'ed PTEs/PMDs writable, resulting in uffd-wp not triggering on write access. Note that do_numa_page() / do_huge_pmd_numa_page() can be reached even without NUMA hinting (which currently doesn't seem to be applicable to shmem), for example, by using uffd-wp with a PROT_WRITE shmem VMA. On such a VMA, userfaultfd-wp is currently non-functional. Note that when enabling userfaultfd-wp, there is no need to walk page tables to enforce the new default protection for the PTEs: we know that they cannot be uffd-wp'ed yet, because that can only happen after enabling uffd-wp for the VMA in general. Also note that this makes mprotect() on ranges with uffd-wp'ed PTEs not accidentally set the write bit -- which would result in uffd-wp not triggering on later write access. This commit makes uffd-wp on shmem behave just like uffd-wp on anonymous memory in that regard, even though, mixing mprotect with uffd-wp is controversial.

Peter Xu	3b8ede6665	mm/hugetlb: pre-allocate pgtable pages for uffd wr-protects ... commit fed15f1345dc8a7fc8baa81e8b55c3ba010d7f4b upstream. Userfaultfd-wp uses pte markers to mark wr-protected pages for both shmem and hugetlb. Shmem has pre-allocation ready for markers, but hugetlb path was overlooked. Doing so by calling huge_pte_alloc() if the initial pgtable walk fails to find the huge ptep. It's possible that huge_pte_alloc() can fail with high memory pressure, in that case stop the loop immediately and fail silently. This is not the most ideal solution but it matches with what we do with shmem meanwhile it avoids the splat in dmesg.

David Hildenbrand	8d6a675cd7	mm/hugetlb: fix uffd-wp handling for migration entries in hugetlb_change_protection() ... commit 44f86392bdd165da7e43d3c772aeb1e128ffd6c8 upstream. We have to update the uffd-wp SWP PTE bit independent of the type of migration entry. Currently, if we're unlucky and we want to install/clear the uffd-wp bit just while we're migrating a read-only mapped hugetlb page, we would miss to set/clear the uffd-wp bit. Further, if we're processing a readable-exclusive migration entry and neither want to set or clear the uffd-wp bit, we could currently end up losing the uffd-wp bit. Note that the same would hold for writable migrating entries, however, having a writable migration entry with the uffd-wp bit set would already mean that something went wrong. Note that the change from !is_readable_migration_entry -> writable_migration_entry is harmless and actually cleaner, as raised by Miaohe Lin and discussed in [1].

David Hildenbrand	6062c992e9	mm/hugetlb: fix PTE marker handling in hugetlb_change_protection() ... commit 0e678153f5be7e6c8d28835f5a678618da4b7a9c upstream. Patch series "mm/hugetlb: uffd-wp fixes for hugetlb_change_protection()". Playing with virtio-mem and background snapshots (using uffd-wp) on hugetlb in QEMU, I managed to trigger a VM_BUG_ON(). Looking into the details, hugetlb_change_protection() seems to not handle uffd-wp correctly in all cases. Patch #1 fixes my test case. I don't have reproducers for patch #2, as it requires running into migration entries. I did not yet check in detail yet if !hugetlb code requires similar care. This patch (of 2): There are two problematic cases when stumbling over a PTE marker in hugetlb_change_protection(): (1) We protect an uffd-wp PTE marker a second time using uffd-wp: we will end up in the "!huge_pte_none(pte)" case and mess up the PTE marker. (2) We unprotect a uffd-wp PTE marker: we will similarly end up in the "!huge_pte_none(pte)" case even though we cleared the PTE, because the "pte" variable is stale. We'll mess up the PTE marker. For example, if we later stumble over such a "wrongly modified" PTE marker, we'll treat it like a present PTE that maps some garbage page. This can, for example, be triggered by mapping a memfd backed by huge pages, registering uffd-wp, uffd-wp'ing an unmapped page and (a) uffd-wp'ing it a second time; or (b) uffd-unprotecting it; or (c) unregistering uffd-wp. Then, ff we trigger fallocate(FALLOC_FL_PUNCH_HOLE) on that file range, we will run into a VM_BUG_ON: [ 195.039560] page:00000000ba1f2987 refcount:1 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x0 [ 195.039565] flags: 0x7ffffc0001000(reserved|node=0|zone=0|lastcpupid=0x1fffff) [ 195.039568] raw: 0007ffffc0001000 ffffe742c0000008 ffffe742c0000008 0000000000000000 [ 195.039569] raw: 0000000000000000 0000000000000000 00000001ffffffff 0000000000000000 [ 195.039569] page dumped because: VM_BUG_ON_PAGE(compound && !PageHead(page)) [ 195.039573] ------------[ cut here ]------------ [ 195.039574] kernel BUG at mm/rmap.c:1346!

However, instead, make it clearer that there are no fall-through statements: we process each case (hwpoison, migration, marker, !none, none) and then unlock the page table to continue with the next PTE. Let's avoid "continue" statements and use a single spin_unlock() at the end.
