stable-backporting the VM_PFNMAP TLB flushing fix (b67fbebd4cf9)

by Jann Horn

commit b67fbebd4cf9 ("mmu_gather: Force tlb-flush VM_PFNMAP vmas") fixes a TLB flushing bug that probably affects some x86 graphics drivers, although hitting the bug might be fairly gnarly. Still, it'd probably be a bad idea to leave it unfixed in the stable kernels that things like Debian stable rely on. Unfortunately the way the fix is written, it relies on refactoring prep work in the three preceding commits, and trying to apply those to older kernels will result in a bunch of merge conflicts. Would it be acceptable here to fix the issue in a completely different way in stable to minimize merge conflicts? Or should the refactoring prep work and the fix commit all be backported? A minimal but also completely different fix would be: diff --git a/mm/mmap.c b/mm/mmap.c index a50042918cc7..c453a1274305 100644 --- a/mm/mmap.c +++ b/mm/mmap.c @@ -2665,6 +2665,18 @@ static void unmap_region(struct mm_struct *mm, tlb_gather_mmu(&tlb, mm, start, end); update_hiwater_rss(mm); unmap_vmas(&tlb, vma, start, end); + + /* + * Ensure we have no stale TLB entries by the time this mapping is + * removed from the rmap. + * Note that we don't have to worry about nested flushes here because + * we're holding the mm semaphore for removing the mapping - so any + * concurrent flush in this region has to be coming through the rmap, + * and we synchronize against that using the rmap lock. + */ + if ((vma->vm_flags & (VM_PFNMAP|VM_MIXEDMAP)) != 0) + tlb_flush_mmu(&tlb); + free_pgtables(&tlb, vma, prev ? prev->vm_end : FIRST_USER_ADDRESS, next ? next->vm_start : USER_PGTABLES_CEILING); tlb_finish_mmu(&tlb, start, end);

In do_exception(), vma->vm_flags is checked against that before calling handle_mm_fault(). Since commit 92f842eac7ee3 ("[S390] store indication fault optimization"), we call handle_mm_fault() with FAULT_FLAG_WRITE, when recognizing that it was a write access. However, the vma flags check is still only checking against (VM_READ | VM_WRITE | VM_EXEC), and therefore also calling handle_mm_fault() with FAULT_FLAG_WRITE in cases where the vma does not allow VM_WRITE. Fix this by changing access check in do_exception() to VM_WRITE only, when recognizing write access.
