From: Harald Welte Date: Thu, 17 Nov 2005 23:06:47 +0000 (-0800) Subject: [NETFILTER] ip_conntrack: fix ftp/irc/tftp helpers on ports >= 32768 X-Git-Tag: v2.6.15-rc2~39^2~3 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2fce76afdb067fa3e7f8ee33c9fe366bd65887ea;p=linux-2.6 [NETFILTER] ip_conntrack: fix ftp/irc/tftp helpers on ports >= 32768 Since we've converted the ftp/irc/tftp helpers to use the new module_parm_array() some time ago, we ware accidentially using signed data types - thus preventing those modules from being used on ports >= 32768. This patch fixes it by using 'ushort' module parameters. Thanks to Jan Nijs for reporting this bug. Signed-off-by: Harald Welte Signed-off-by: David S.
