The purpose of this section is to document what is the current practice regarding clean-up patches which address checkpatch warnings and similar problems. I feel there is a value in having this documented so others can easily refer to it. Clearly this topic is subjective. And to some extent the current practice discourages a wider range of patches than is described here. But I feel it is best to start somewhere, with the most well established part of the current practice. Signed-off-by:

Kuniyuki Iwashima says: ==================== rtnetlink: Handle error of rtnl_register_module(). While converting phonet to per-netns RTNL, I found a weird comment /* Further rtnl_register_module() cannot fail */ that was true but no longer true after commit addf9b90 ("net: rtnetlink: use rcu to free rtnl message handlers"). Many callers of rtnl_register_module() just ignore the returned value but should handle them properly. This series introduces two helpers, rtnl_register_many() and rtnl_unregister_many(), to do that easily and fix such callers. All rtnl_register() and rtnl_register_module() will be converted to _many() variant and some rtnl_lock() will be saved in _many() later in net-next. Changes: v4: * Add more context in changelog of each patch v3: https://lore.kernel.org/all/20241007124459.5727-1-kuniyu@amazon.com/ * Move module *owner to struct rtnl_msg_handler * Make struct rtnl_msg_handler args/vars const * Update mctp goto labels v2: https://lore.kernel.org/netdev/20241004222358.79129-1-kuniyu@amazon.com/ * Remove __exit from mctp_neigh_exit(). v1: https://lore.kernel.org/netdev/20241003205725.5612-1-kuniyu@amazon.com/ ==================== Link: https://patch.msgid.link/20241008184737.9619-1-kuniyu@amazon.comSigned-off-by:

Before commit addf9b90 ("net: rtnetlink: use rcu to free rtnl message handlers"), once the first rtnl_register_module() allocated rtnl_msg_handlers[PF_PHONET], the following calls never failed. However, after the commit, rtnl_register_module() could fail silently to allocate rtnl_msg_handlers[PF_PHONET][msgtype] and requires error handling for each call. Handling the error allows users to view a module as an all-or-nothing thing in terms of the rtnetlink functionality. This prevents syzkaller from reporting spurious errors from its tests, where OOM often occurs and module is automatically loaded. Let's use rtnl_register_many() to handle the errors easily.

Before commit addf9b90 ("net: rtnetlink: use rcu to free rtnl message handlers"), once rtnl_msg_handlers[protocol] was allocated, the following rtnl_register_module() for the same protocol never failed. However, after the commit, rtnl_msg_handler[protocol][msgtype] needs to be allocated in each rtnl_register_module(), so each call could fail. Many callers of rtnl_register_module() do not handle the returned error, and we need to add many error handlings. To handle that easily, let's add wrapper functions for bulk registration of rtnetlink message handlers. Signed-off-by:

dst_entries_add() uses per-cpu data that might be freed at netns dismantle from ip6_route_net_exit() calling dst_entries_destroy() Before ip6_route_net_exit() can be called, we release all the dsts associated with this netns, via calls to dst_release(), which waits an rcu grace period before calling dst_destroy() dst_entries_add() use in dst_destroy() is racy, because dst_entries_destroy() could have been called already. Decrementing the number of dsts must happen sooner. Notes: 1) in CONFIG_XFRM case, dst_destroy() can call dst_release_immediate(child), this might also cause UAF if the child does not have DST_NOCOUNT set. IPSEC maintainers might take a look and see how to address this. 2) There is also discussion about removing this count of dst, which might happen in future kernels.

In a previous fix, the in-kernel path-manager has been modified not to retrigger the removal of a subflow if it was already closed, e.g. when the initial subflow is removed, but kept in the subflows list. To be complete, this fix should also skip the subflows that are in any closing state: mptcp_close_ssk() will initiate the closure, but the switch to the TCP_CLOSE state depends on the other peer.

As reported by Christoph [1], before this patch, an MPTCP connection was wrongly reset when a host received a first data packet with MPTCP options after the 3wHS, but got the next ones without. According to the MPTCP v1 specs [2], a fallback should happen in this case, because the host didn't receive a DATA_ACK from the other peer, nor receive data for more than the initial window which implies a DATA_ACK being received by the other peer. The patch here re-uses the same logic as the one used in other places: by looking at allow_infinite_fallback, which is disabled at the creation of an additional subflow. It's not looking at the first DATA_ACK (or implying one received from the other side) as suggested by the RFC, but it is in continuation with what was already done, which is safer, and it fixes the reported issue. The next step, looking at this first DATA_ACK, is tracked in [4]. This patch has been validated using the following Packetdrill script: 0 socket(..., SOCK_STREAM, IPPROTO_MPTCP) = 3 +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +0 bind(3, ..., ...) = 0 +0 listen(3, 1) = 0 // 3WHS is OK +0.0 < S 0:0(0) win 65535 <mss 1460, sackOK, nop, nop, nop, wscale 6, mpcapable v1 flags[flag_h] nokey> +0.0 > S. 0:0(0) ack 1 <mss 1460, nop, nop, sackOK, nop, wscale 8, mpcapable v1 flags[flag_h] key[skey]> +0.1 < . 1:1(0) ack 1 win 2048 <mpcapable v1 flags[flag_h] key[ckey=2, skey]> +0 accept(3, ..., ...) = 4 // Data from the client with valid MPTCP options (no DATA_ACK: normal) +0.1 < P. 1:501(500) ack 1 win 2048 <mpcapable v1 flags[flag_h] key[skey, ckey] mpcdatalen 500, nop, nop> // From here, the MPTCP options will be dropped by a middlebox +0.0 > . 1:1(0) ack 501 <dss dack8=501 dll=0 nocs> +0.1 read(4, ..., 500) = 500 +0 write(4, ..., 100) = 100 // The server replies with data, still thinking MPTCP is being used +0.0 > P. 1:101(100) ack 501 <dss dack8=501 dsn8=1 ssn=1 dll=100 nocs, nop, nop> // But the client already did a fallback to TCP, because the two previous packets have been received without MPTCP options +0.1 < . 501:501(0) ack 101 win 2048 +0.0 < P. 501:601(100) ack 101 win 2048 // The server should fallback to TCP, not reset: it didn't get a DATA_ACK, nor data for more than the initial window +0.0 > . 101:101(0) ack 601 Note that this script requires Packetdrill with MPTCP support, see [3].

The repro enables pmtu on the loopback device, leading to tcp_mtu_probe() generating very large probe packets. tcp_can_coalesce_send_queue_head() currently does not check for mptcp-level invariants, and allowed the creation of cross-DSS probes, leading to the mentioned corruption. Address the issue teaching tcp_can_coalesce_send_queue_head() about mptcp using the tcp_skb_can_collapse(), also reducing the code duplication.

In case of a tc mirred action from one switch to another, the behavior is not correct. We simply tell the source switch driver to program a mirroring entry towards mirror->to_local_port = to_dp->index, but it is not even guaranteed that the to_dp belongs to the same switch as dp. For proper cross-chip support, we would need to go through the cross-chip notifier layer in switch.c, program the entry on cascade ports, and introduce new, explicit API for cross-chip mirroring, given that intermediary switches should have introspection into the DSA tags passed through the cascade port (and not just program a port mirror on the entire cascade port).

Some platforms (such as i.MX25 and i.MX27) do not support PTP, so on these platforms fec_ptp_init() is not called and the related members in fep are not initialized. However, fec_ptp_save_state() is called unconditionally, which causes the kernel to panic. Therefore, add a condition so that fec_ptp_save_state() is not called if PTP is not supported.

syzbot managed to call xt_cluster match via ebtables: WARNING: CPU: 0 PID: 11 at net/netfilter/xt_cluster.c:72 xt_cluster_mt+0x196/0x780 [..] ebt_do_table+0x174b/0x2a40 Module registers to NFPROTO_UNSPEC, but it assumes ipv4/ipv6 packet processing. As this is only useful to restrict locally terminating TCP/UDP traffic, register this for ipv4 and ipv6 family only. Pablo points out that this is a general issue, direct users of the set/getsockopt interface can call into targets/matches that were only intended for use with ip(6)tables. Check all UNSPEC matches and targets for similar issues: - matches and targets are fine except if they assume skb_network_header() is valid -- this is only true when called from inet layer: ip(6) stack pulls the ip/ipv6 header into linear data area. - targets that return XT_CONTINUE or other xtables verdicts must be restricted too, they are incompatbile with the ebtables traverser, e.g. EBT_CONTINUE is a completely different value than XT_CONTINUE. Most matches/targets are changed to register for NFPROTO_IPV4/IPV6, as they are provided for use by ip(6)tables. The MARK target is also used by arptables, so register for NFPROTO_ARP too. While at it, bail out if connbytes fails to enable the corresponding conntrack family. This change passes the selftests in iptables.git.

If hashing fails in sctp_listen_start(), the socket remains in the LISTENING state, even though it was not added to the hash table. This can lead to a scenario where a socket appears to be listening without actually being accessible. This patch ensures that if the hashing operation fails, the sk_state is set back to CLOSED before returning an error. Note that there is no need to undo the autobind operation if hashing fails, as the bind port can still be used for next listen() call on the same socket.

This patch addresses a macvlan leak issue in the i40e driver caused by concurrent access to vsi->mac_filter_hash. The leak occurs when multiple threads attempt to modify the mac_filter_hash simultaneously, leading to inconsistent state and potential memory leaks. To fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing vf->default_lan_addr.addr with spin_lock/unlock_bh(&vsi->mac_filter_hash_lock), ensuring atomic operations and preventing concurrent access. Additionally, we add lockdep_assert_held(&vsi->mac_filter_hash_lock) in i40e_add_mac_filter() to help catch similar issues in the future. Reproduction steps: 1. Spawn VFs and configure port vlan on them. 2. Trigger concurrent macvlan operations (e.g., adding and deleting portvlan and/or mac filters). 3. Observe the potential memory leak and inconsistent state in the mac_filter_hash. This synchronization ensures the integrity of the mac_filter_hash and prevents the described leak.

Triggering the reset while in switchdev mode causes errors[1]. Rules are already removed by this time because switch content is flushed in case of the reset. This means that rules were deleted from HW but SW still thinks they exist so when we get SWITCHDEV_FDB_DEL_TO_DEVICE notification we try to delete not existing rule. We can avoid these errors by clearing the rules early in the reset flow before they are removed from HW. Switchdev API will get notified that the rule was removed so we won't get SWITCHDEV_FDB_DEL_TO_DEVICE notification. Remove unnecessary ice_clear_sw_switch_recipes.

netif_is_ice() works by checking the pointer to netdev ops. However, it only checks for the default ice_netdev_ops, not ice_netdev_safe_mode_ops, so in Safe Mode it always returns false, which is unintuitive. While it doesn't look like netif_is_ice() is currently being called anywhere in Safe Mode, this could change and potentially lead to unexpected behaviour.

If DDP package is missing or corrupted, the driver should enter Safe Mode. Instead, an error is returned and probe fails. To fix this, don't exit init if ice_init_ddp_config() returns an error.
