From: krw Date: Wed, 14 Jun 2017 15:57:25 +0000 (+0000) Subject: Start consolidating client_state into interface_info. First X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=eea1c0a9968a2da37343f868f6c261daecd78f7a;p=openbsd Start consolidating client_state into interface_info. First fields to move: recv_packet, sent_packet and sent_packet_length. No intentional functional change. --- diff --git a/sbin/dhclient/bpf.c b/sbin/dhclient/bpf.c index c298f63de80..ffb7f1d5606 100644 --- a/sbin/dhclient/bpf.c +++ b/sbin/dhclient/bpf.c @@ -1,4 +1,4 @@ -/* $OpenBSD: bpf.c,v 1.51 2017/06/13 15:49:32 krw Exp $ */ +/* $OpenBSD: bpf.c,v 1.52 2017/06/14 15:57:25 krw Exp $ */ /* BPF socket interface code, originally contributed by Archie Cobbs. */ @@ -262,9 +262,9 @@ send_packet(struct interface_info *ifi, struct in_addr from, struct in_addr to) struct udphdr udp;
