TestVerifierErrorAnnotation builds a deliberately-broken kernel-side program (Lookup followed by an unchecked dereference), loads it, and asserts that

ThisCpuPtr wraps the BPF helper `bpf_this_cpu_ptr`. Take a pointer to a percpu ksym, *percpu_ptr*, and return a pointer to the percpu kernel variab

TimerCancel wraps the BPF helper `bpf_timer_cancel`. Cancel the timer and wait for callback_fn to finish if it was running. Returns 0 if the time

TimerInit wraps the BPF helper `bpf_timer_init`. Initialize the timer. First 4 bits of *flags* specify clockid. Only CLOCK_MONOTONIC, CLOCK_REALTI

TimerSetCallback wraps the BPF helper `bpf_timer_set_callback`. Configure the timer to call *callback_fn* static function. Returns 0 on success.

TimerStart wraps the BPF helper `bpf_timer_start`. Set timer expiration N nanoseconds from the current time. The configured callback will be invoke

TracePrintk wraps the BPF helper `bpf_trace_printk`. This helper is a "printk()-like" facility for debugging. It prints a message defined by forma

WriteSourceMap writes the sourcemap text representation to w.

XdpAdjustHead wraps the BPF helper `bpf_xdp_adjust_head`. Adjust (move) *xdp_md*\ **->data** by *delta* bytes. Note that it is possible to use a ne

XdpAdjustMeta wraps the BPF helper `bpf_xdp_adjust_meta`. Adjust the address pointed by *xdp_md*\ **->data_meta** by *delta* (which can be positive

XdpAdjustTail wraps the BPF helper `bpf_xdp_adjust_tail`. Adjust (move) *xdp_md*\ **->data_end** by *delta* bytes. It is possible to both shrink an

XdpGetBuffLen wraps the BPF helper `bpf_xdp_get_buff_len`. Get the total size of a given xdp buff (linear and paged area) Returns The total size

XdpLoadBytes wraps the BPF helper `bpf_xdp_load_bytes`. This helper is provided as an easy way to load data from a xdp buffer. It can be used to lo

XdpOutput wraps the BPF helper `bpf_xdp_output`. Write raw *data* blob into a special BPF perf event held by *map* of type **BPF_MAP_TYPE_PERF_EVEN

XdpStoreBytes wraps the BPF helper `bpf_xdp_store_bytes`. Store *len* bytes from buffer *buf* into the frame associated to *xdp_md*, at *offset*.
