* int bpf_spin_lock(struct bpf_spin_lock *lock)
* Description
* Acquire a spinlock represented by the pointer *lock*, which is
* stored as part of a value of a map. Taking the lock allows to
* safely update the rest of the fields in that value. The
* spinlock can (and must) later be released with a call to
* **bpf_spin_unlock**\ (\ *lock*\ ).
*
* Spinlocks in BPF programs come with a number of restrictions
* and constraints:
*
* * **bpf_spin_lock** objects are only allowed inside maps of
* types **BPF_MAP_TYPE_HASH** and **BPF_MAP_TYPE_ARRAY** (this
* list could be extended in the future).
* * BTF description of the map is mandatory.
* * The BPF program can take ONE lock at a time, since taking two
* or more could cause dead locks.
* * Only one **struct bpf_spin_lock** is allowed per map element.
* * When the lock is taken, calls (either BPF to BPF or helpers)
* are not allowed.
* * The **BPF_LD_ABS** and **BPF_LD_IND** instructions are not
* allowed inside a spinlock-ed region.
* * The BPF program MUST call **bpf_spin_unlock**\ () to release
* the lock, on all execution paths, before it returns.
* * The BPF program can access **struct bpf_spin_lock** only via
* the **bpf_spin_lock**\ () and **bpf_spin_unlock**\ ()
* helpers. Loading or storing data into the **struct
* bpf_spin_lock** *lock*\ **;** field of a map is not allowed.
* * To use the **bpf_spin_lock**\ () helper, the BTF description
* of the map value must be a struct and have **struct
* bpf_spin_lock** *anyname*\ **;** field at the top level.
* Nested lock inside another struct is not allowed.
* * The **struct bpf_spin_lock** *lock* field in a map value must
* be aligned on a multiple of 4 bytes in that value.
* * Syscall with command **BPF_MAP_LOOKUP_ELEM** does not copy
* the **bpf_spin_lock** field to user space.
* * Syscall with command **BPF_MAP_UPDATE_ELEM**, or update from
* a BPF program, do not update the **bpf_spin_lock** field.
* * **bpf_spin_lock** cannot be on the stack or inside a
* networking packet (it can only be inside of a map values).
* * **bpf_spin_lock** is available to root only.
* * Tracing programs and socket filter programs cannot use
* **bpf_spin_lock**\ () due to insufficient preemption checks
* (but this may change in the future).
* * **bpf_spin_lock** is not allowed in inner maps of map-in-map.
* Return
* 0

* A **struct bpf_tcp_sock** pointer on success, or **NULL** in

*
* int bpf_skb_ecn_set_ce(struct sk_buf *skb)
* Description
* Sets ECN of IP header to ce (congestion encountered) if
* current value is ect (ECN capable). Works with IPv6 and IPv4.
* Return
* 1 if set, 0 if not set.
* Description
* Set ECN (Explicit Congestion Notification) field of IP header
* to **CE** (Congestion Encountered) if current value is **ECT**
* (ECN Capable Transport). Otherwise, do nothing. Works with IPv6
* and IPv4.
* Return
* 1 if the **CE** flag is set (either by the current helper call
* or because it was already present), 0 if it is not set.
*
* struct bpf_sock *bpf_get_listener_sock(struct bpf_sock *sk)
* Description
* Return a **struct bpf_sock** pointer in **TCP_LISTEN** state.
