From: Cong Wang Date: Sun, 25 Aug 2019 12:35:06 +0000 (-0700) Subject: kernel: net_sched: fix a NULL pointer deref in ipt action X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fstintel.git;a=commitdiff_plain;h=7735cce0c5c306bd9eea20ca2805e4a492c02be9 kernel: net_sched: fix a NULL pointer deref in ipt action 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.
