* actual packet size (resulting in negative packet size) will in
* principle not exceed the MTU, which is why it is not considered
* a failure. Other BPF helpers are needed for performing the
* planned size change; therefore the responsibility for catching
* a negative packet size belongs in those helpers.
* Specifying ifindex zero means the MTU check is performed
* against the current net device. This is practical if this isn't
* used prior to redirect.
* On input mtu_len must be a valid pointer, else verifier will
* reject BPF program. If the value mtu_len is initialized to

* is done against. Remember XDP and TC length operate at L2, but
* this value is L3 as this correlate to MTU and IP-header tot_len
* values which are L3 (similar behavior as bpf_fib_lookup).
* The Linux kernel route table can configure MTUs on a more
* specific per route level, which is not provided by this helper.

* following values:
* BPF_MTU_CHK_SEGS
* This flag will only works for ctx struct sk_buff.
* If packet context contains extra packet segment buffers
* (often knows as GSO skb), then MTU check is harder to
* check at this point, because in transmit path it is
* possible for the skb packet to get re-segmented
* (depending on net device features). This could still be
* a MTU violation, so this flag enables performing MTU
* check against segments, with a different violation
* return code to tell it apart. Check cannot use len_diff.
* On return mtu_len pointer contains the MTU value of the net

* - 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

* Copy a NUL terminated string from an unsafe user address

* char buf[PATHLEN]; // PATHLEN is defined to 256
* int res = bpf_probe_read_user_str(buf, sizeof(buf),

* // can use res (the string length) as event
* // size, after checking its boundaries.
* }
*
* In comparison, using bpf_probe_read_user\ () helper here
* instead to read the string would require to estimate the length
* at compile time, and would often result in copying more memory
* than necessary.
* Another useful use case is when parsing individual process
* arguments or individual environment variables navigating
* current\ ->mm->arg_start and current
* ->mm->env_start: using this helper and the return value,
* one can quickly iterate at the right offset of the memory area.
