[PATCH] Revert "vmgenid: emit uevent when VMGENID updates"

by Jason A. Donenfeld

This reverts commit ad6bcdad2b6724e113f191a12f859a9e8456b26d. I had nak'd it, and Greg said on the thread that it links that he wasn't going to take it either, especially since it's not his code or his tree, but then, seemingly accidentally, it got pushed up some months later, in what looks like a mistake, with no further discussion in the linked thread. So revert it, since it's clearly not intended.

[PATCH] Revert "f2fs: stop allocating pinned sections if EAGAIN happens"

by Wu Bo

This reverts commit 2e42b7f817acd6e8d78226445eb6fe44fe79c12a. If the GC victim section has a pinned block when fallocate() trigger FG_GC, the section is not able to be recycled. And this will return -EAGAIN cause fallocate() failed, even though there are much spare space as user see. As the GC policy prone to chose the same victim, fallocate() may not successed at a long period. This scenario has been found during Android OTA.

[PATCH v3] mm: Fix race between __split_huge_pmd_locked() and GUP-fast

by Ryan Roberts

__split_huge_pmd_locked() can be called for a present THP, devmap or (non-present) migration entry. It calls pmdp_invalidate() unconditionally on the pmdp and only determines if it is present or not based on the returned old pmd. This is a problem for the migration entry case because pmd_mkinvalid(), called by pmdp_invalidate() must only be called for a present pmd. On arm64 at least, pmd_mkinvalid() will mark the pmd such that any future call to pmd_present() will return true. And therefore any lockless pgtable walker could see the migration entry pmd in this state and start interpretting the fields as if it were present, leading to BadThings (TM). GUP-fast appears to be one such lockless pgtable walker. x86 does not suffer the above problem, but instead pmd_mkinvalid() will corrupt the offset field of the swap entry within the swap pte. See link below for discussion of that problem. Fix all of this by only calling pmdp_invalidate() for a present pmd. And for good measure let's add a warning to all implementations of pmdp_invalidate[_ad](). I've manually reviewed all other pmdp_invalidate[_ad]() call sites and believe all others to be conformant. This is a theoretical bug found during code review. I don't have any test case to trigger it in practice. Cc: stable(a)vger.kernel.org Link: https://lore.kernel.org/all/0dd7827a-6334-439a-8fd0-43c98e6af22b@arm.com/ Fixes: 84c3fc4e9c56 ("mm: thp: check pmd migration entry in common path") Signed-off-by: Ryan Roberts <ryan.roberts(a)arm.com> --- Right v3; this goes back to the original approach in v1 to fix core-mm rather than push the fix into arm64, since we discovered that x86 can't handle pmd_mkinvalid() being called for non-present pmds either. I'm pulling in more arch maintainers because this version adds some warnings in arch code to help spot incorrect usage. Although Catalin had already accepted v2 (fixing arm64) [2] into for-next/fixes, he's agreed to either remove or revert it. Changes since v1 [1] ==================== - Improve pmdp_mkinvalid() docs to make it clear it can only be called for present pmd (per JohnH, Zi Yan) - Added warnings to arch overrides of pmdp_invalidate[_ad]() (per Zi Yan) - Moved comment next to new location of pmpd_invalidate() (per Zi Yan) [1] https://lore.kernel.org/linux-mm/20240425170704.3379492-1-ryan.roberts@arm.… [2] https://lore.kernel.org/all/20240430133138.732088-1-ryan.roberts@arm.com/ Thanks, Ryan Documentation/mm/arch_pgtable_helpers.rst | 6 ++- arch/powerpc/mm/book3s64/pgtable.c | 1 + arch/s390/include/asm/pgtable.h | 4 +- arch/sparc/mm/tlb.c | 1 + arch/x86/mm/pgtable.c | 2 + mm/huge_memory.c | 49 ++++++++++++----------- mm/pgtable-generic.c | 2 + 7 files changed, 39 insertions(+), 26 deletions(-) diff --git a/Documentation/mm/arch_pgtable_helpers.rst b/Documentation/mm/arch_pgtable_helpers.rst index 2466d3363af7..ad50ca6f495e 100644 --- a/Documentation/mm/arch_pgtable_helpers.rst +++ b/Documentation/mm/arch_pgtable_helpers.rst @@ -140,7 +140,8 @@ PMD Page Table Helpers +---------------------------+--------------------------------------------------+ | pmd_swp_clear_soft_dirty | Clears a soft dirty swapped PMD | +---------------------------+--------------------------------------------------+ -| pmd_mkinvalid | Invalidates a mapped PMD [1] | +| pmd_mkinvalid | Invalidates a present PMD; do not call for | +| | non-present PMD [1] | +---------------------------+--------------------------------------------------+ | pmd_set_huge | Creates a PMD huge mapping | +---------------------------+--------------------------------------------------+ @@ -196,7 +197,8 @@ PUD Page Table Helpers +---------------------------+--------------------------------------------------+ | pud_mkdevmap | Creates a ZONE_DEVICE mapped PUD | +---------------------------+--------------------------------------------------+ -| pud_mkinvalid | Invalidates a mapped PUD [1] | +| pud_mkinvalid | Invalidates a present PUD; do not call for | +| | non-present PUD [1] | +---------------------------+--------------------------------------------------+ | pud_set_huge | Creates a PUD huge mapping | +---------------------------+--------------------------------------------------+ diff --git a/arch/powerpc/mm/book3s64/pgtable.c b/arch/powerpc/mm/book3s64/pgtable.c index 83823db3488b..2975ea0841ba 100644 --- a/arch/powerpc/mm/book3s64/pgtable.c +++ b/arch/powerpc/mm/book3s64/pgtable.c @@ -170,6 +170,7 @@ pmd_t pmdp_invalidate(struct vm_area_struct *vma, unsigned long address, { unsigned long old_pmd; + VM_WARN_ON_ONCE(!pmd_present(*pmdp)); old_pmd = pmd_hugepage_update(vma->vm_mm, address, pmdp, _PAGE_PRESENT, _PAGE_INVALID); flush_pmd_tlb_range(vma, address, address + HPAGE_PMD_SIZE); return __pmd(old_pmd); diff --git a/arch/s390/include/asm/pgtable.h b/arch/s390/include/asm/pgtable.h index 60950e7a25f5..480bea44559d 100644 --- a/arch/s390/include/asm/pgtable.h +++ b/arch/s390/include/asm/pgtable.h @@ -1768,8 +1768,10 @@ static inline pmd_t pmdp_huge_clear_flush(struct vm_area_struct *vma, static inline pmd_t pmdp_invalidate(struct vm_area_struct *vma, unsigned long addr, pmd_t *pmdp) { - pmd_t pmd = __pmd(pmd_val(*pmdp) | _SEGMENT_ENTRY_INVALID); + pmd_t pmd; + VM_WARN_ON_ONCE(!pmd_present(*pmdp)); + pmd = __pmd(pmd_val(*pmdp) | _SEGMENT_ENTRY_INVALID); return pmdp_xchg_direct(vma->vm_mm, addr, pmdp, pmd); } diff --git a/arch/sparc/mm/tlb.c b/arch/sparc/mm/tlb.c index b44d79d778c7..ef69127d7e5e 100644 --- a/arch/sparc/mm/tlb.c +++ b/arch/sparc/mm/tlb.c @@ -249,6 +249,7 @@ pmd_t pmdp_invalidate(struct vm_area_struct *vma, unsigned long address, { pmd_t old, entry; + VM_WARN_ON_ONCE(!pmd_present(*pmdp)); entry = __pmd(pmd_val(*pmdp) & ~_PAGE_VALID); old = pmdp_establish(vma, address, pmdp, entry); flush_tlb_range(vma, address, address + HPAGE_PMD_SIZE); diff --git a/arch/x86/mm/pgtable.c b/arch/x86/mm/pgtable.c index d007591b8059..103cbccf1d7d 100644 --- a/arch/x86/mm/pgtable.c +++ b/arch/x86/mm/pgtable.c @@ -631,6 +631,8 @@ int pmdp_clear_flush_young(struct vm_area_struct *vma, pmd_t pmdp_invalidate_ad(struct vm_area_struct *vma, unsigned long address, pmd_t *pmdp) { + VM_WARN_ON_ONCE(!pmd_present(*pmdp)); + /* * No flush is necessary.

[PATCH 6.1 1/1] tls: fix race between tx work scheduling and socket close

by Lee Jones

From: Jakub Kicinski <kuba(a)kernel.org> [ Upstream commit e01e3934a1b2d122919f73bc6ddbe1cdafc4bbdb ] Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling complete(). This seems more logical in the first place, as it's the inverse order of what the submitting thread will do.
