Instead of keeping only the best IP and PXE offers, store all of them, and pick the best to use just before a request is sent. This allows priority differentiation to work even when lower-priority offers provide PXE options, and improves robustness at sites with broken PXE servers intermingled with working ones: when a ProxyDHCP request times out, instead of giving up, we try the next PXE offer we've received. It also allows us to avoid breaking up combined IP+PXE offers, which can be important with some firewall configurations. This behavior matches that of most vendor PXE ROMs. Store a reference to the DHCPOFFER packet in the offer structure, so that when registering settings after a successful ACK we can register the proxy PXE settings we originally received; this removes the need for a nonstandard duplicate REQUEST/ACK to port 67 of proxy servers like dnsmasq that provide PXE options in the OFFER. Total cost: 450 bytes uncompressed. Signed-off-by: Marty Connor <mdc@etherboot.org> |
