-Subject: [Patch net] net_sched: fix a NULL pointer deref in ipt action
-Date: Sun, 25 Aug 2019 10:01:32 -0700
-
-The net pointer in struct xt_tgdtor_param is not explicitly
-initialized therefore is still NULL when dereferencing it.
-So we have to find a way to pass the correct net pointer to
-ipt_destroy_target().
-
-The best way I find is just saving the net pointer inside the per
-netns struct tcf_idrinfo, which could make this patch smaller.
-
-Fixes: 0c66dc1ea3f0 ("netfilter: conntrack: register hooks in netns when needed by ruleset")
