Subject: datatype: Fix boolean type on Big Endian
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=aec699af2a006b1dd6580abb95910c402e306fa9;p=thirdparty%2Fnftables.git

datatype: Fix boolean type on Big Endian

Pass a reference to a variable with correct size when creating the
expression, otherwise mpz_import_data() will read only the always zero
upper byte on Big Endian hosts.

Fixes: afb6a8e66a111 ("datatype: clamp boolean value to 0 and 1")
