2019 +1000 # # powerpc/64s: Fix THP PMD collapse serialisation # # Commit 1b2443a547f9 ("powerpc/book3s64: Avoid multiple endian # conversion in pte helpers") changed the actual bitwise tests in # pte_access_permitted by using pte_write() and pte_present() helpers # rather than raw bitwise testing _PAGE_WRITE and _PAGE_PRESENT bits. # # The pte_present change now returns true for ptes which are # !_PAGE_PRESENT and _PAGE_INVALID, which is the combination used by # pmdp_invalidate to synchronize access from lock-free lookups. # pte_access_permitted is used by pmd_access_permitted, so allowing GUP # lock free access to proceed with such PTEs breaks this # synchronisation. # # This bug has been observed on HPT host, with random crashes and # corruption in guests, usually together with bad PMD messages in the # host. # # Fix this by adding an explicit check in pmd_access_permitted, and # documenting the condition explicitly. # # The pte_write() change should be okay, and would prevent GUP from # falling back to the slow path when encountering savedwrite ptes, which # matches what x86 (that does not implement savedwrite) does. # # Fixes: 1b2443a547f9 ("powerpc/book3s64: Avoid
