Hi list, I''m trying to setup a Linux box with a complicated source routing and could use a hand from you. The box has 4 NICs and lots of VLANs attached. It is a firewall and router in the following scenario: (obs: IP addresses have being changed for security purposes) - eth0 holds the default route (GW: 200.1.0.1, Firewall: 200.1.0.2); - The box is routing and sometimes source

Digging more, loadfile("192.0.2.1::pxe.0", &file.data, &file.size), queries DNS, which sounds like it doesn't follow the same call path as a COM32 calling pxe_dns(). If the DNS won't resolve the IP, things won't load properly. pxechn.c32 sets sname in the intended packet to "192.0.2.1" which may be confusing something. More debugging needed. -- -Gene

From: Sylvain Gault <sylvain.gault at gmail.com> Despite having native network capabilities, UEFI 2.4 (the most widely deployed at the moment) has no native DNS resolver. I propose here an implementation more or less inspired by the one found in core/legacynet/dnsresolv.c. Since it's non-trivial, I'd like to ask for a deep review of this code. I tried to make it as strong as possible against malformed packets and should be devoided of remote code execution or infinite loops (contrary to the legacynet implementation), but I may have forgotten som...
