Hello,

recently I added a new option that can be set for an integer modparam: PARAM_USE_SHM (i.e., PARAM_INT | PARAM_USE_SHM). The pointer given in the exports structure has to be the address of a pointer to an int. The result is that the modparam will allocated an integer in shared memory and store the provided value there. It makes it possible to change the value at runtime via the new rpc command: modparam.setn.

An example of use is the keylog_mode parameter from tls module.

This should simplify coding in the future when one needs to add a new int parameter that can be changed at runtime, without need to code the full set of allocating shared memory and implementing dedicated rpc commands.

There are several such parameters already (e.g., all these modparams to enable/disable features like for sipdump), they can be reviewed if they should be migrated or not, but it is also fine to be kept like they are, some of they might have custom processing behind the rpc command.

Cheers, Daniel
