So we must mask the var type first, then shift it by `CFG_INPUT_SHIFT`, before or-ing it with the rest. What happened before was that the entire type was shifted, and that included var type, input type and flags. What we end up with is some additional higher bits set (for flags). I actually discovered this while adding an additional flag that was meant to mark variables as private, only accessible through an internal API (not available to modules such as cfg_rpc). --- Modified: src/core/cfg/cfg.c --- Diff: https://github.com/kamailio/kamailio/commit/c3b2eacbba1097ed3d40cff18ea2d51… Patch: https://github.com/kamailio/kamailio/commit/c3b2eacbba1097ed3d40cff18ea2d51… --- diff --git a/src/core/cfg/cfg.c b/src/core/cfg/cfg.c index 3822a9c94d..488d72f35a 100644 --- a/src/core/cfg/cfg.c +++ b/src/core/cfg/cfg.c @@ -94,7 +94,7 @@ int cfg_declare(char *group_name, cfg_def_t *def, void *values, int def_size, /* verify the type of the input */ if (CFG_INPUT_MASK(def[i].type)==0) { - def[i].type |= def[i].type << CFG_INPUT_SHIFT; + def[i].type |= CFG_VAR_MASK(def[i].type) << CFG_INPUT_SHIFT; } else { if ((CFG_INPUT_MASK(def[i].type) != CFG_VAR_MASK(def[i].type) << CFG_INPUT_SHIFT) && (def[i].on_change_cb == 0)) {
