Howlett <Liam.Howlett@oracle.com> # Date: Fri Feb 24 16:20:55 2023 -0500 # # mm/mprotect: Fix successful vma_merge() of next in do_mprotect_pkey() # # If mprotect_fixup() successfully calls vma_merge() and replaces vma and # the next vma, then the tmp variable in the do_mprotect_pkey() is not # updated to point to the new vma end. This results in the loop detecting # a gap between VMAs that does not exist. # # Fix the faulty value of tmp by setting it to the end location of the vma # iterator at the end of the loop. # # Link: https://lkml.kernel.org/r/20230224212055.1786100-1-Liam.Howlett@oracle.com # Fixes: 2286a6914c77 ("mm: change mprotect_fixup to vma iterator") # Link: https://lore.kernel.org/linux-mm/20230223120407.729110a6ecd1416ac59d9cb0@linux-foundation.org/ # Signed-off-by: Liam R.
