Date: Thu, 2 Feb 2017 12:49:44 +1100 From: Stephen Rothwell <sfr@...b.auug.org.au> To: David Miller <davem@...emloft.net>, Networking <netdev@...r.kernel.org> Cc: linux-next@...r.kernel.org, linux-kernel@...r.kernel.org, Yotam Gigi <yotamg@...lanox.com> Subject: linux-next: manual merge of the net-next tree with Linus' tree Hi all, Today's linux-next merge of the net-next tree got a conflict in: net/sched/cls_matchall.c between commit: fd62d9f5c575 ("net/sched: matchall: Fix configuration race") from Linus' tree and commit: ec2507d2a306 ("net/sched: cls_matchall: Fix error path") from the net-next tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc net/sched/cls_matchall.c index b12bc2abea93,fcecf5aac666..000000000000 --- a/net/sched/cls_matchall.c +++ b/net/sched/cls_matchall.c @@@ -118,19 -141,24 +118,24 @@@ static int mall_set_parms(struct net *n struct tcf_exts e; int err; - tcf_exts_init(&e, TCA_MATCHALL_ACT, 0); + err = tcf_exts_init(&e, TCA_MATCHALL_ACT, 0); + if (err) + return err; err = tcf_exts_validate(net, tp, tb, est, &e, ovr); if (err < 0) - return err; + goto errout; if (tb[TCA_MATCHALL_CLASSID]) { - f->res.classid = nla_get_u32(tb[TCA_MATCHALL_CLASSID]); - tcf_bind_filter(tp, &f->res, base); + head->res.classid = nla_get_u32(tb[TCA_MATCHALL_CLASSID]); + tcf_bind_filter(tp, &head->res, base); } - tcf_exts_change(tp, &f->exts, &e); + tcf_exts_change(tp, &head->exts, &e); return 0; + errout: + tcf_exts_destroy(&e); + return err; } static int mall_change(struct net *net, struct sk_buff *in_skb, @@@ -162,39 -194,43 +167,44 @@@ return -EINVAL; } - f = kzalloc(sizeof(*f), GFP_KERNEL); - if (!f) + new = kzalloc(sizeof(*new), GFP_KERNEL); + if (!new) return -ENOBUFS; - tcf_exts_init(&new->exts, TCA_MATCHALL_ACT, 0); - err = tcf_exts_init(&f->exts, TCA_MATCHALL_ACT, 0); ++ err = tcf_exts_init(&new->exts, TCA_MATCHALL_ACT, 0); + if (err) + goto err_exts_init; if (!handle) handle = 1; - f->handle = handle; - f->flags = flags; + new->handle = handle; + new->flags = flags; - err = mall_set_parms(net, tp, f, base, tb, tca[TCA_RATE], ovr); + err = mall_set_parms(net, tp, new, base, tb, tca[TCA_RATE], ovr); if (err) - goto errout; + goto err_set_parms; if (tc_should_offload(dev, tp, flags)) { - err = mall_replace_hw_filter(tp, f, (unsigned long) f); + err = mall_replace_hw_filter(tp, new, (unsigned long) new); if (err) { if (tc_skip_sw(flags)) - goto errout; + goto err_replace_hw_filter; else err = 0; } } - *arg = (unsigned long) f; - rcu_assign_pointer(head->filter, f); - + *arg = (unsigned long) head; + rcu_assign_pointer(tp->root, new); + if (head) + call_rcu(&head->rcu, mall_destroy_rcu); return 0; - errout: + err_replace_hw_filter: + err_set_parms: - tcf_exts_destroy(&f->exts); ++ tcf_exts_destroy(&new->exts); + err_exts_init: - kfree(f); + kfree(new); return err; }
