#include <mitigator_bpf.h>

Detailed Description

Packet flow information.

All fields are in network byte order, that is, port numbers must be swapped to check against values. For example, test if port is 1234 as follows:

struct Flow flow;
packet_flow(ctx, &flow);
if (flow.dst_port == bswap16(1234)) { ... }
bswap16
LOCAL uint16_t bswap16(uint16_t value)
Change byte order of a 16-bit value.
