Thanks for the patch, finally had an opportunity to apply it and test it. It did require disabling -Werror in order for the diff that was originally supplied to compile, as there's a couple of variables that were throwing uninitialized warnings.

This is work in progress, but this works for me in test environment. Patch changes net_bootp to implement full DHCP transaction. it still /should/ work with BOOTP pure server (untested, I do not have one). It also re-implements option processing to support overloaded fields and consolidates it in one place. What is currently not implemented - per interface, per transaction stage retransmit timer. Will be done. - DHCP server selection. We take first DHCPOFFER or BOOTPREPLY. No plans to implement. - DHCP option concatenation (RFC3396). I do not expect to hit it in real life; could be implemented relatively easy if needed. - client identifier (RFC6842). I do not expect to hit it in real life; could be added easily if needed. _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
