This is an RFC patch to add support for configuring RADIUS server address using Fully Qualified Domain Names (FQDN). The patch in current form implements this support. The drawback is that resolving is done in a syncronous manner. That is, the entire hostapd process locks up for the duration of resolving. One way to solve this would be to use, for instance, c-ares[1]. Besides the syncronous nature of resolving, which at first glance seems rather straight forward to fix, this patch unfortunately breaks failover in the case a primary RADIUS server address is configured to a FQDN that fails to resolve at startup. I cannot for the life of me grok the code enough to realize why this is. hostapd simply never try the secondary configured address. Any and all comments, suggestions, and help is deeply appreciated.
