From 1a8218e96271790a07dd7065a2ef173e0f67e328 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 15 May 2011 21:26:31 +0000 Subject: [PATCH] net: ping: dont call udp_ioctl() udp_ioctl() really handles UDP and UDPLite protocols. 1) It can increment UDP_MIB_INERRORS in case first_packet_length() finds a frame with bad checksum. 2) It has a dependency on sizeof(struct udphdr), not applicable to ICMP/PING If ping sockets need to handle SIOCINQ/SIOCOUTQ ioctl, this should be done differently.
