[ Upstream commit 833d4313bc1e9e194814917d23e8874d6b651649 ]
The backport of this whole series for v6.12, containing these commits...
- e7b9ecce562c ("tcp: convert to dev_net_rcu()") - 15492700ac41 ("tcp: cache RTAX_QUICKACK metric in a hot cache line") - 88fe14253e18 ("net: dst: add four helpers to annotate data-races around dst->dev") - a74fc62eec15 ("ipv4: adopt dst_dev, skb_dst_dev and skb_dst_dev_net[_rcu]") - 1dbf1d590d10 ("net: Add locking to protect skb->dev access in ip_output") - 108a86c71c93 ("mptcp: Call dst_release() in mptcp_active_enable().") - 893c49a78d9f ("mptcp: Use __sk_dst_get() and dst_dev_rcu() in mptcp_active_enable().") - 833d4313bc1e ("mptcp: reset blackhole on success with non-loopback ifaces")
... looks good to me, if that's also OK for Eric and/or Kuniyuki.
Please note that these commits should also help to backport a few more fixes from Kuniyuki from this series:
https://lore.kernel.org/20250916214758.650211-1-kuniyu@google.com
- 3d3466878afd ("smc: Fix use-after-free in __pnet_find_base_ndev().") - 935d783e5de9 ("smc: Use __sk_dst_get() and dst_dev_rcu() in in smc_clc_prfx_set().") - 235f81045c00 ("smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match().") - 0b0e4d51c655 ("smc: Use __sk_dst_get() and dst_dev_rcu() in smc_vlan_by_tcpsk().") - c65f27b9c3be ("tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().")
And also eventually commit b62a59c18b69 ("tcp: use dst_dev_rcu() in tcp_fastopen_active_disable_ofo_check()") from Eric.
(I don't know who will initiate these backports.)
Cheers, Matt
