  • c244deda57 config: Added IPv4 and IPv6 address support Bhaskar Kataria 2021-11-11 23:29:00 +05:30
  • ebefec595d config: Create required interfaces in BNG Shashank D 2021-11-11 20:11:17 +05:30
  • 813cfa2719 Working prototype (IPv4) with interface name in Option 82 Circuit ID Yoel Caspersen 2021-11-09 16:35:37 +01:00
  • 17f1da535f First working prototype (IPv4 DHCP relay works in both directions) Yoel Caspersen 2021-11-05 14:36:44 +01:00
  • 8d91b1409e Upstream direction works with QinQ packets only When allowing packets with 1 VLAN tag only, verifier complains about BPF program being too large. Compiled with LLVM 13. Yoel Caspersen 2021-10-25 22:23:16 +02:00
  • 83b9795ec9 Adding custom memcpy and memset functions to pass verifier checks Built-in memcpy and memset functions cause verifier to complain about misaligned stack access. To get around that (and be able to copy a dynamic number of bytes via memcpy), two custom functions are added. This version of the relay uses interface name + VLAN identifiers in option 82 circuit ID (left-aligned, length IF_NAMESIZE with trailing null bytes). Yoel Caspersen 2021-10-24 15:02:15 +02:00
  • a9003fa266 Reformatting option 82 circuit ID to include interface name (including VLAN tags) in ASCII format. main Yoel Caspersen 2021-10-18 09:20:16 +02:00
  • ac9373c82e Increasing IP and UDP length headers to match Ethernet frame tail adjustment. Adding map client_vlans which allows matching server responses with client requests. Reformatting Option 82 to include interface name (work in progress, we need to figure out how to convert VLAN tags to ASCII). Yoel Caspersen 2021-10-17 10:41:06 +02:00
  • 37f30d5811 Update README Yoel Caspersen 2021-10-15 10:17:03 +02:00
  • 09bc68580f Moving Option 82 to end of options as per RFC3046 section 2.1. Adjusting tail instead of headers because of complications with variable length DHCP options - beware that this doesn't appear to work with veth interfaces. Use a physical NIC for testing for now.
