From e1b2aa7f3051e268973b6126fdca602ac4af6bc4 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 1 Sep 2012 09:57:40 +0000 Subject: [PATCH] fddi: 64 bit bug in smt_add_para() The intent was to set 4 bytes of data so that's why the sp_len is set to 4 on the next line. The cast to u_long pointer clears 8 bytes on 64 bit arches. Signed-off-by: Dan Carpenter Signed-off-by: David S.
