Subject: [Test] Fix FFI string-to-pointer conversions for cffi-lua
X-Git-Tag: 3.14.2~24
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ac60e42090b9ccceeb3244861073e98935265bbf;p=thirdparty%2Frspamd.git

[Test] Fix FFI string-to-pointer conversions for cffi-lua

cffi-lua is stricter than LuaJIT FFI and requires explicit conversion
of Lua strings to C pointers. Use ffi.new/ffi.copy for the conversion.
