Error in 1.1.8 when there is no entry for radius port in /etc/services

[jordil2]

The issue was introduced in version 1.1.8. The rc_getaddrinfo function (at /lib/ip_util.c) calls getaddrinfo(). This function returns an error when the "radius" (or "radius-acct") service is not defined in the /etc/services file. The library should take this case into account and use the default value.

As a workaround, I've used this code in rc_getaddrinfo:

     char defport[10];

...
if (flags & PW_AI_AUTH)
{
	service = "radius";
	snprintf(defport,  sizeof(defport), "%d", PW_AUTH_UDP_PORT);		
}
else if (flags & PW_AI_ACCT)
{
	service = "radius-acct";
	snprintf(defport, sizeof(defport), "%d", PW_ACCT_UDP_PORT);		
}
err = getaddrinfo(host, service, &hints, &res);
if (err != 0) {
	/* Execute again using the default (old) radius port number */
	hints.ai_flags |= AI_NUMERICSERV; 
	err = getaddrinfo(host, defport, &hints, &res);
	if (err != 0) {
		return NULL;
	} 		
}

@jordil2 could you share the exact code using our library causing the reported error? it will be helpful to validate the report.
