This means that when a\nsocket policy is in use, dst entries returned by xfrm_lookup have\na refcount of 2, and are not freed when no longer in use.\n\nCc: Wei Wang <weiwan@google.com>\nFixes: 52df157f17 (\"xfrm: take refcnt of dst when creating struct xfrm_dst bundle\")\nTested: https://android-review.googlesource.com/417481\nTested: https://android-review.googlesource.com/418659\nTested: https://android-review.googlesource.com/424463\nTested: https://android-review.googlesource.com/452776 passes on net-next\nSigned-off-by: Lorenzo Colitti <lorenzo@google.com>\nAcked-by: Wei Wang <weiwan@google.com>\nSigned-off-by: Steffen Klassert <steffen.klassert@secunet.com>\n---\n net/xfrm/xfrm_policy.c | 1 -\n 1 file changed, 1 deletion(-)", "diff": "diff --git a/net/xfrm/xfrm_policy.c b/net/xfrm/xfrm_policy.c\nindex 6f5a0dad..69b16ee 100644\n--- a/net/xfrm/xfrm_policy.c\n+++ b/net/xfrm/xfrm_policy.c\n@@ -2226,7 +2226,6 @@ struct dst_entry *xfrm_lookup(struct net *net, struct dst_entry *dst_orig,\n \t\t\t\tgoto no_transform;\n \t\t\t}\n \n-\t\t\tdst_hold(&xdst->u.dst);\n \t\t\troute = xdst->route;\n \t\t}\n \t}\n", "prefixes": [ "1/7" ] }
