针对你提出的“bpf: failed to load program: invalid argument”问题,我将根据提供的tips进行分点回答: 确认bpf程序是否正确编写: bpf程序需要遵循特定的语法和规则。检查程序是否使用了正确的指令集,以及是否满足BPF的限制(如程序大小、指令数量等)。 示例代码检查(假设使用C语言): c #include <linux/bpf....

首先,我们需要设置一个bpf_program对象,以便可以通过将其传递给ioctl()来设置一个过滤程序。bpf_program的结构如下所示: structbpf_program{// Size: 0x10u_intbf_len;// 0x00structbpf_insn*bf_insns;// 0x08}; 请注意,bf_len保存的不是以字节为单位的程序指令大小,而是长度。这意味着,我们为bf_len指定...
