[PATCH] libbpf: Replace strcpy() with memcpy() in bpf_object__new()

From: Suchit Karunakaran
Date: Thu Jul 17 2025 - 08:01:28 EST


Replace the unsafe strcpy() call with memcpy() when copying the path
into the bpf_object structure. Since the memory is pre-allocated to
exactly strlen(path) + 1 bytes and the length is already known, memcpy()
is safer than strcpy().
