From 0aead543479e7f20013217fe3fc33a604fdd8944 Mon Sep 17 00:00:00 2001 From: Rami Rosen Date: Tue, 5 Feb 2008 02:56:48 -0800 Subject: [PATCH] [NET_SCHED]: Add #ifdef CONFIG_NET_EMATCH in net/sched/cls_flow.c (latest git broken build) The 2.6 latest git build was broken when using the following configuration options: CONFIG_NET_EMATCH=n CONFIG_NET_CLS_FLOW=y with the following error: net/sched/cls_flow.c: In function 'flow_dump': net/sched/cls_flow.c:598: error: 'struct tcf_ematch_tree' has no member named 'hdr' make[2]: *** [net/sched/cls_flow.o] Error 1 make[1]: *** [net/sched] Error 2 make: *** [net] Error 2 see the recent post by Li Zefan: http://www.spinics.net/lists/netdev/msg54434.html The reason for this crash is that struct tcf_ematch_tree (net/pkt_cls.h) is empty when CONFIG_NET_EMATCH is not defined. When CONFIG_NET_EMATCH is defined, the tcf_ematch_tree structure indeed holds a struct tcf_ematch_tree_hdr (hdr) as flow_dump() expects. This patch adds #ifdef CONFIG_NET_EMATCH in flow_dump to avoid this. Signed-off-by: Rami Rosen Signed-off-by: David S.
