Struct nf_conntrack
WebThe nfct field in the skb is a pointer to inside the struct ip_conntrack, at one of the infos[] array. Hence we can tell the state of the skb by which element in this array it is pointing to: this pointer encodes both the state structure and the relationship of this skb to that state. ... You can look inside the `struct nf_info' to get ...

Web} When btf_struct_access is _set_, the expectation is that btf_struct_access has full control over accesses, including if writes are allowed. Rather than carve out an exception for each prog type that may write to BTF ptrs, delete the redundant check and give full control to btf_struct_access.

This "tuple"structure is used to represent a unidirectional packet ow by its network-layer and transport-layer addresses. Bidirectional ows are thus represented using a tuple for each direction. Figure 4 shows a simpli ed representation of struct nf_conntrack_tuple. The data structure uses unions to contain both protocol-
