+  *
+  * s64 bpf_tcp_gen_syncookie(struct bpf_sock *sk, void *iph, u32 iph_len, struct tcphdr *th, u32 th_len)
+  *	Description
+  *		Try to issue a SYN cookie for the packet with corresponding
+  *		IP/TCP headers, *iph* and *th*, on the listening socket in *sk*.
+  *
+  *		*iph* points to the start of the IPv4 or IPv6 header, while
+  *		*iph_len* contains **sizeof**\ (**struct iphdr**) or
+  *		**sizeof**\ (**struct ip6hdr**).
+  *
+  *		*th* points to the start of the TCP header, while *th_len*
+  *		contains the length of the TCP header.
+  *
+  *	Return
+  *		On success, lower 32 bits hold the generated SYN cookie in
+  *		followed by 16 bits which hold the MSS value for that cookie,
+  *		and the top 16 bits are unused.
+  *
+  *		On failure, the returned value is one of the following:
+  *
+  *		**-EINVAL** SYN cookie cannot be issued due to error
+  *
+  *		**-ENOENT** SYN cookie should not be issued (no SYN flood)
+  *
+  *		**-EOPNOTSUPP** kernel configuration does not enable SYN cookies
+  *
+  *		**-EPROTONOSUPPORT** IP packet version is not 4 or 6

+  * CO-RE relocate single instruction.
+  *
+  * The outline and important points of the algorithm:
+  * 1. For given local type, find corresponding candidate target types.
+  *    Candidate type is a type with the same "essential" name, ignoring
+  *    everything after last triple underscore (___). E.g., `sample`,
+  *    `sample___flavor_one`, `sample___flavor_another_one`, are all candidates
+  *    for each other. Names with triple underscore are referred to as
+  *    "flavors" and are useful, among other things, to allow to
+  *    specify/support incompatible variations of the same kernel struct, which
+  *    might differ between different kernel versions and/or build
+  *    configurations.
+  *
+  *    N.B. Struct "flavors" could be generated by bpftool's BTF-to-C
+  *    converter, when deduplicated BTF of a kernel still contains more than
+  *    one different types with the same name. In that case, ___2, ___3, etc
+  *    are appended starting from second name conflict. But start flavors are
+  *    also useful to be defined "locally", in BPF program, to extract same
+  *    data from incompatible changes between different kernel
+  *    versions/configurations. For instance, to handle field renames between
+  *    kernel versions, one can use two flavors of the struct name with the
+  *    same common name and use conditional relocations to extract that field,
+  *    depending on target kernel version.
+  * 2. For each candidate type, try to match local specification to this
+  *    candidate target type. Matching involves finding corresponding
+  *    high-level spec accessors, meaning that all named fields should match,
+  *    as well as all array accesses should be within the actual bounds. Also,
+  *    types should be compatible (see bpf_core_fields_are_compat for details).
+  * 3. It is supported and expected that there might be multiple flavors
+  *    matching the spec. As long as all the specs resolve to the same set of
+  *    offsets across all candidates, there is not error. If there is any
+  *    ambiguity, CO-RE relocation will fail. This is necessary to accomodate
+  *    imprefection of BTF deduplication, which can cause slight duplication of
+  *    the same BTF type, if some directly or indirectly referenced (by
+  *    pointer) type gets resolved to different actual types in different
+  *    object files. If such situation occurs, deduplicated BTF will end up
+  *    with two (or more) structurally identical types, which differ only in
+  *    types they refer to through pointer. This should be OK in most cases and
+  *    is not an error.
+  * 4. Candidate types search is performed by linearly scanning through all
+  *    types in target BTF. It is anticipated that this is overall more
+  *    efficient memory-wise and not significantly worse (if not better)
+  *    CPU-wise compared to prebuilding a map from all local type names to
+  *    a list of candidate type names. It's also sped up by caching resolved
+  *    list of matching candidates per each local "root" type ID, that has at
+  *    least one bpf_offset_reloc associated with it. This list is shared
+  *    between multiple relocations for the same type ID and is updated as some
+  *    of the candidates are pruned due to structural incompatibility.
