Subject: netfilter: don't xt_jumpstack_alloc twice in xt_register_table
X-Git-Tag: v2.6.35-rc2~64^2~7^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c936e8bd1de2fa50c49e3df6fa5036bf07870b67;p=pandora-kernel.git

netfilter: don't xt_jumpstack_alloc twice in xt_register_table

In xt_register_table, xt_jumpstack_alloc is called first, later
xt_replace_table is used. But in xt_replace_table, xt_jumpstack_alloc
will be used again. Then the memory allocated by previous xt_jumpstack_alloc
will be leaked. We can simply remove the previous xt_jumpstack_alloc because
there aren't any users of newinfo between xt_jumpstack_alloc and
xt_replace_table.
