Add client address parameter to the plugin function mosquitto_auth_unpwd_check?

[leojay]

Right now, there is no way to verify the ip address of the client. Do you think ip address can be added to the mosquitto_auth_unpwd_check plugin function?
Or, as an alternative, provide a function to get the address from a mosquitto*?
Thanks!

Happily, this is already available in the mosquitto_broker.h header:

/*
 * Function: mosquitto_client_address
 *
 * Retrieve the IP address of the client as a string.
 */
const char *mosquitto_client_address(const struct mosquitto *client);

It isn't installed on the ubuntu or debian packages though, I'll fix that. I can't comment on other packages.

But how do I use this function? does that mean I have to link my plugin against libmosquitto.so?

The function is provided in the mosquitto broker itself and is accessible to the plugin once it has been loaded by the broker. All you should need to do is #include <mosquitto_broker.h> and then call the function.
