In that case if seg6_hmac_init() fails, thegenl_unregister_family() isn t called.This issue exist since commit 46738b1317e1 ( ipv6: sr: add option to controllwtunnel support ), and commit 5559cea2d5aa ( ipv6: sr: fix possibleuse-after-free and null-ptr-deref ) replaced unregister_pernet_subsys()with genl_unregister_family() in this error path.
