Currently there is no straightforward way to fill dynptr memory with a value (most commonly zero). One can do it with bpf_dynptr_write(), but a temporary buffer is necessary for that. Implement bpf_dynptr_memset() - an analogue of memset() from libc. Signed-off-by: Ihor Solodrai <isolodrai@meta.com>
Add tests to verify the behavior of bpf_dynptr_memset(): * normal memset 0 * memset in dynptr that was adjusted * error: size overflow * error: readonly dynptr Signed-off-by: Ihor Solodrai <isolodrai@meta.com>
