However,\ndumping just the header part of the set was not protected against\nunderlying resizing. Fix it by protecting the header dumping part\nas well.\n\nReported-by: syzbot+786c889f046e8b003ca6@syzkaller.appspotmail.com\nSigned-off-by: Jozsef Kadlecsik <kadlec@netfilter.org>\nSigned-off-by: Florian Westphal <fw@strlen.de>\n---\n net/netfilter/ipset/ip_set_core.c | 4 ++--\n 1 file changed, 2 insertions(+), 2 deletions(-)", "diff": "diff --git a/net/netfilter/ipset/ip_set_core.c b/net/netfilter/ipset/ip_set_core.c\nindex a2fe711cb5e3..2cc04da95afd 100644\n--- a/net/netfilter/ipset/ip_set_core.c\n+++ b/net/netfilter/ipset/ip_set_core.c\n@@ -1648,13 +1648,13 @@ ip_set_dump_do(struct sk_buff *skb, struct netlink_callback *cb)\n \t\t\tif (cb->args[IPSET_CB_PROTO] > IPSET_PROTOCOL_MIN &&\n \t\t\t nla_put_net16(skb, IPSET_ATTR_INDEX, htons(index)))\n \t\t\t\tgoto nla_put_failure;\n+\t\t\tif (set->variant->uref)\n+\t\t\t\tset->variant->uref(set, cb, true);\n \t\t\tret = set->variant->head(set, skb);\n \t\t\tif (ret < 0)\n \t\t\t\tgoto release_refcount;\n \t\t\tif (dump_flags & IPSET_FLAG_LIST_HEADER)\n \t\t\t\tgoto next_set;\n-\t\t\tif (set->variant->uref)\n-\t\t\t\tset->variant->uref(set, cb, true);\n \t\t\tfallthrough;\n \t\tdefault:\n \t\t\tret = set->variant->list(set, skb, cb);\n", "prefixes": [ "net", "03/14" ] }
