Message-ID: <20200601182245.GA23230@ZenIV.linux.org.uk> (raw)

	Regularize the sitation with uaccess checksum primitives, fold
csum_partial_... into csum_and_copy_..._user(), on x86 collapse several
access_ok()/stac()/clac() into user_access_begin()/user_access_end()

  default csum_and_copy_to_user(): don't bother with access_ok() (2020-05-29 16:11:50 -0400)

----------------------------------------------------------------
Al Viro (15):

      x86_64: csum_..._copy_..._user(): switch to unsafe_..._user()
      x86: switch both 32bit and 64bit to providing csum_and_copy_from_user()
      x86: switch 32bit csum_and_copy_to_user() to user_access_{begin,end}()
      ia64: csum_partial_copy_nocheck(): don't abuse csum_partial_copy_from_user()
      ia64: turn csum_partial_copy_from_user() into csum_and_copy_from_user()
      alpha: turn csum_partial_copy_from_user() into csum_and_copy_from_user()
      parisc: turn csum_partial_copy_from_user() into csum_and_copy_from_user()
      sparc: switch to providing csum_and_copy_from_user()
      xtensa: switch to providing csum_and_copy_from_user()
      m68k: convert to csum_and_copy_from_user()
      sh32: convert to csum_and_copy_from_user()
      arm: switch to csum_and_copy_from_user()
      take the dummy csum_and_copy_from_user() into net/checksum.h
      default csum_and_copy_to_user(): don't bother with access_ok()
