Description of problem:

If the last read request returns an empty string, the command output is not getting logged.

Bug is around line 462 of rhnsd.c:


		ret = waitpid(child, &retval, WNOHANG);
		if (ret == child) {
		    /* huh, status changed, we're done */
		    if (strlen(buffer) > 0)
			syslog(LOG_INFO, "%s returned: %s", RHN_CHECK, buf);
		    free(buf);
                    close(fds[0]); /* plug in fd leak */


Instead of:

if (strlen(buffer) > 0)

this should be:

if (strlen(buf) > 0)
