hi, Paul:<br>
we got one kernel panic on 4.9 kernel <br>
<br>
[16237.397896] [2018:10:09 23:06:55]audit: audit_pid=20802 reset <br>
[16238.098916] [2018:10:09 23:06:57]Unable to handle kernel NULL pointer dereference at virtual address 00000280<br>
<br>
audit_sock is set to NULL in kauditd_send_skb, but later we are access it again in audit_replace caused this panic. <br>
is there patch for such SW issue on 4.9 kernel ?<br>
<br>
static int audit_replace(pid_t pid)<br>
{<br>
struct sk_buff *skb = audit_make_reply(0, 0, AUDIT_REPLACE, 0, 0,<br>
&pid, sizeof(pid));<br>
<br>
if (!skb)<br>
return -ENOMEM;<br>
return netlink_unicast(audit_sock, skb, audit_nlk_portid, 0);<br>
} <br>
<br>
<br>
