*
* *sk* must be a non-**NULL** pointer to a full socket, e.g. one
* returned from **bpf_sk_lookup_xxx**\ (),
* **bpf_sk_fullsock**\ (), etc. The format of returned id is
* same as in **bpf_skb_cgroup_id**\ ().
*
* This helper is available only if the kernel was compiled with

* Return
* The id is returned or 0 in case the id could not be retrieved.

* Description
* Return id of cgroup v2 that is ancestor of cgroup associated
* with the *sk* at the *ancestor_level*. The root cgroup is at
* *ancestor_level* zero and each step down the hierarchy
* increments the level. If *ancestor_level* == level of cgroup
* associated with *sk*, then return value will be same as that

* that are upper in hierarchy than immediate cgroup associated
* with *sk*.

* u64 bpf_ringbuf_query(void *ringbuf, u64 flags)
* Description
* Query various characteristics of provided ring buffer. What
* exactly is queries is determined by *flags*:
* - BPF_RB_AVAIL_DATA - amount of data not yet consumed;
* - BPF_RB_RING_SIZE - the size of ring buffer;
* - BPF_RB_CONS_POS - consumer position (can wrap around);
* - BPF_RB_PROD_POS - producer(s) position (can wrap around);
* Data returned is just a momentary snapshots of actual values
* and could be inaccurate, so this facility should be used to
* power heuristics and for reporting, not to make 100% correct
* calculation.
* Return
* Requested value, or 0, if flags are not recognized.
*
* int bpf_csum_level(struct sk_buff *skb, u64 level)
* Description
* Change the skbs checksum level by one layer up or down, or
* reset it entirely to none in order to have the stack perform
* checksum validation. The level is applicable to the following
* protocols: TCP, UDP, GRE, SCTP, FCOE. For example, a decap of
* | ETH | IP | UDP | GUE | IP | TCP | into | ETH | IP | TCP |
* through **bpf_skb_adjust_room**\ () helper with passing in
* **BPF_F_ADJ_ROOM_NO_CSUM_RESET** flag would require one call
* to **bpf_csum_level**\ () with **BPF_CSUM_LEVEL_DEC** since
* the UDP header is removed. Similarly, an encap of the latter
* into the former could be accompanied by a helper call to
* **bpf_csum_level**\ () with **BPF_CSUM_LEVEL_INC** if the
* skb is still intended to be processed in higher layers of the
* stack instead of just egressing at tc.
*
* There are three supported level settings at this time:
*
* * **BPF_CSUM_LEVEL_INC**: Increases skb->csum_level for skbs
* with CHECKSUM_UNNECESSARY.
* * **BPF_CSUM_LEVEL_DEC**: Decreases skb->csum_level for skbs
* with CHECKSUM_UNNECESSARY.
* * **BPF_CSUM_LEVEL_RESET**: Resets skb->csum_level to 0 and
* sets CHECKSUM_NONE to force checksum validation by the stack.
* * **BPF_CSUM_LEVEL_QUERY**: No-op, returns the current
* skb->csum_level.
* Return
* 0 on success, or a negative error in case of failure. In the
* case of **BPF_CSUM_LEVEL_QUERY**, the current skb->csum_level
* is returned or the error code -EACCES in case the skb is not
* subject to CHECKSUM_UNNECESSARY.
