  "message": "netfilter: ipt_LOG: add bufferisation to call printk() once\n\nipt_LOG \u0026 ip6t_LOG use lot of calls to printk() and use a lock in a hope\nseveral cpus wont mix their output in syslog.\n\nprintk() being very expensive [1], its better to call it once, on a\nprebuilt and complete line. Also, with mixed IPv4 and IPv6 trafic,\nseparate IPv4/IPv6 locks dont avoid garbage.\n\nI used an allocation of a 1024 bytes structure, sort of seq_printf() but\nwith a fixed size limit.\nUse a static buffer if dynamic allocation failed.\n\nEmit a once time alert if buffer size happens to be too short.\n\n[1]: printk() has various features like printk_delay()...\n\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: Patrick McHardy \u003ckaber@trash.net\u003e\n",
