If anyone has any objections, please let me know. ------------------ From: yuan.gao [ Upstream commit 4c0856c225b39b1def6c9a6bc56faca79550da13 ] When the ping program uses an IPPROTO_ICMP socket to send ICMP_ECHO messages, ICMP_MIB_OUTMSGS is counted twice. ping_v4_sendmsg ping_v4_push_pending_frames ip_push_pending_frames ip_finish_skb __ip_make_skb icmp_out_count(net, icmp_type); // first count icmp_out_count(sock_net(sk), user_icmph.type); // second count However, when the ping program uses an IPPROTO_RAW socket, ICMP_MIB_OUTMSGS is counted correctly only once. Therefore, the first count should be removed.
