# Instead of using GUP, make fault_in_safe_writeable() actually force a # 'handle_mm_fault()' using the same fixup_user_fault() machinery that # futexes already use. # # Using the GUP machinery meant that fault_in_safe_writeable() did not do # everything that a real fault would do, ranging from not auto-expanding # the stack segment, to not updating accessed or dirty flags in the page # tables (GUP sets those flags on the pages themselves). # # The latter causes problems on architectures (like s390) that do accessed # bit handling in software, which meant that fault_in_safe_writeable() # didn't actually do all the fault handling it needed to, and trying to # access the user address afterwards would still cause faults. # # Reported-and-tested-by: Andreas Gruenbacher <agruenba@redhat.com> # Fixes: cdd591fc86e3 ("iov_iter: Introduce fault_in_iov_iter_writeable") #
