Fields

data: bpf_md_ptr_t

Start of directly accessible data. It begins from the tcp/udp header.

data_end: bpf_md_end_ptr_t

End of directly accessible data

len: u32

Total length of packet (starting from the tcp/udp header). Note that the directly accessible bytes (data_end - data) could be less than this "len". Those bytes could be indirectly read by a helper "bpf_skb_load_bytes()".

eth_protocol: u32

Eth protocol in the mac header (network byte order). e.g. ETH_P_IP(0x0800) and ETH_P_IPV6(0x86DD)

ip_protocol: u32

IP protocol. e.g. IPPROTO_TCP, IPPROTO_UDP

bind_inany: u32

Is sock bound to an INANY address?

hash: u32

A hash of the packet 4 tuples
