Mô tảsetup_conntrack reads ct_tcp_timeout from NVRAM. If the NVRAM value is absent or does not parse as 10 unsigned integers, the function falls back to reading TCP conntrack timeout values from procfs and formats them into a fixed 72-byte stack buffer. char buf[72]; v11 = read_conntrack_timeout("tcp", "established"); v12 = read_conntrack_timeout("tcp", "syn_sent"); v13 = read_conntrack_timeout("tcp", "syn_recv"); v14 = read_conntrack_timeout("tcp", "fin_wait"); v15 = read_conntrack_timeout("tcp", "time_wait"); v16 = read_conntrack_timeout("tcp", "close"); v17 = read_conntrack_timeout("tcp", "close_wait"); v18 = read_conntrack_timeout("tcp", "last_ack"); sprintf(buf, "0 %u %u %u %u %u %u %u %u 0", v11, v12, v13, v14, v15, v16, v17, v18); nvram_set("ct_tcp_timeout", buf); In the worst case, the formatted output is approximately 92 bytes, exceeding the 72-byte destination buffer.
