Revision 51d7f707c4d4e84599979e5859025d3ff2623d6b authored by gray on 26 May 2023, 03:18:40 UTC, committed by Daniel Borkmann on 20 June 2023, 14:46:04 UTC
The previous implementation of BPFProgram.Test() only allowed passing and returning bytes as *skb->data, without the ability to specify input skb metadata or check output skb metadata. This commit introduces a new function named runBpfProgram, which passes an additional []byte as input skb metadata and returns an additional []byte as output skb metadata. By utilizing this function, we ensure that the skb->mark set in PKTGEN can be properly passed to the SETUP , and any modifications to skb->mark or skb->cb can be accurately examined during the CHECK for validation purposes. The input ctx bytes will be set as the input skb, briefly you can expect `memcpy(skb, ctx, sizeof(*skb))` happening inside, and you can get skb->mark by `mark := ctx[offset(skb, mark): sizeof(skb->mark)]`.
