lua: CMakeLists: drop redundant cmake_minimum_required

2025-10-07T12:19:11Z

The Lua module depends on the parent ubus project and can't be built independently. Drop redundant cmake_minimum_required from lua/CMakeLists.txt and inherit the version from the parent CMake project to keep version consistency.

lua: workaround false positive dereference of null pointer

2019-12-16T22:39:16Z

scan-build from clang-9 has reported following: ubus.c:837:16: warning: Access to field 'rnotify' results in a dereference of a null pointer (loaded from variable 'sub') sub->rnotify = luaL_ref(L, -2); Which is false positive as the lua_error() does a long jump and therefore never returns and this long jump probably confuses the static analyzer. So this patch workarounds this false positive by helping static analyzer by using common Lua idiom which is to return lua_error()'s return value.
