From: Geliang Tang tanggeliang@kylinos.cn
As Martin mentioned in review comment, there is an existing bug that orig_netns_fd will be leaked in the later "goto fail;" case after open("/proc/self/ns/net") in open_netns() in network_helpers.c. This patch adds "close(token->orig_netns_fd);" before "free(token);" to fix it.
