* struct bpf_sock *bpf_sk_lookup_tcp(void *ctx, struct bpf_sock_tuple *tuple, u32 tuple_size, u32 netns, u64 flags)
* Description
* Look for TCP socket matching *tuple*, optionally in a child
* network namespace *netns*. The return value must be checked,
* and if non-NULL, released via **bpf_sk_release**\ ().
*
* The *ctx* should point to the context of the program, such as

* to determine the base network namespace for the lookup.
*
* *tuple_size* must be one of:

* **sizeof**\ (*tuple*\ **->ipv4**)
* Look for an IPv4 socket.
* **sizeof**\ (*tuple*\ **->ipv6**)
* Look for an IPv6 socket.
*
* If the *netns* is zero, then the socket lookup table in the
* netns associated with the *ctx* will be used. For the TC hooks,
* this in the netns of the device in the skb. For socket hooks,
* this in the netns of the socket. If *netns* is non-zero, then
* it specifies the ID of the netns relative to the netns
* associated with the *ctx*.
*
* All values for *flags* are reserved for future usage, and must
* be left at zero.
*
* This helper is available only if the kernel was compiled with
* **CONFIG_NET** configuration option.
* Return
* Pointer to *struct bpf_sock*, or NULL in case of failure.
*
* struct bpf_sock *bpf_sk_lookup_udp(void *ctx, struct bpf_sock_tuple *tuple, u32 tuple_size, u32 netns, u64 flags)
* Description
* Look for UDP socket matching *tuple*, optionally in a child
* network namespace *netns*. The return value must be checked,
* and if non-NULL, released via **bpf_sk_release**\ ().
*
* The *ctx* should point to the context of the program, such as

* int bpf_sk_release(struct bpf_sock *sk)
* Description
* Release the reference held by *sock*. *sock* must be a non-NULL
* pointer that was returned from bpf_sk_lookup_xxx\ ().
* Return
* 0 on success, or a negative error in case of failure.
*
* int bpf_msg_push_data(struct sk_buff *skb, u32 start, u32 len, u64 flags)
* Description
* For socket policies, insert *len* bytes into msg at offset
* *start*.
*
* If a program of type **BPF_PROG_TYPE_SK_MSG** is run on a
* *msg* it may want to insert metadata or options into the msg.
* This can later be read and used by any of the lower layer BPF
* hooks.
*
* This helper may fail if under memory pressure (a malloc
* fails) in these cases BPF programs will get an appropriate
* error and BPF programs will need to handle them.
*
* Return
* 0 on success, or a negative error in case of failure.
