Heiner Kallweit says: ==================== net: add and use netdev_sw_irq_coalesce_default_on() There are reports about r8169 not reaching full line speed on certain systems (e.g. SBC's) with a 2.5Gbps link. There was a time when hardware interrupt coalescing was enabled per default, but this was changed due to ASPM-related issues on few systems. Meanwhile we have sysfs attributes for controlling kind of "software interrupt coalescing" on the GRO level. However most distros and users don't know about it. So lets set a conservative default for both involved parameters. Users can still override the defaults via sysfs. Don't enable these settings on the fast ethernet chip versions, they are slow enough. Even with these conservative setting interrupt load on my 1Gbps test system reduced significantly. Follow Jakub's suggestion and put this functionality into net core so that other MAC drivers can reuse it. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Add a helper for drivers wanting to set SW IRQ coalescing by default. The related sysfs attributes can be used to override the default values. Follow Jakub's suggestion and put this functionality into net core so that drivers wanting to use software interrupt coalescing per default don't have to open-code it. Note that this function needs to be called before the netdevice is registered. Suggested-by:

Refill RX queue in batches of descriptors to improve performance. Refill is allowed to fail as long as a minimum number of descriptors is active. Thus, a limited number of failed RX buffer allocations is now allowed for normal operation. Previously every failed allocation resulted in a dropped frame. If the minimum number of active descriptors is reached, then RX buffers are still reused and frames are dropped. This ensures that the RX queue never runs empty and always continues to operate. Prework for future XDP support. Signed-off-by:

Without interrupt throttling, iperf server mode generates a CPU load of 100% (A53 1.2GHz). Also the throughput suffers with less than 900Mbit/s on a 1Gbit/s link. The reason is a high interrupt load with interrupts every ~20us. Reduce interrupt load by throttling of interrupts. Interrupt delay default is 64us. For iperf server mode the CPU load is significantly reduced to ~20% and the throughput reaches the maximum of 941MBit/s. Interrupts are generated every ~140us. RX and TX coalesce can be configured with ethtool. RX coalesce has priority over TX coalesce if the same interrupt is used. Signed-off-by:

The main usage of the struct thunderbolt_ip_frame_header is to handle the packets on the media layer. The header is bound to the protocol in which the byte ordering is crucial. However the data type definition doesn't use that and sparse is unhappy, for example (17 altogether): .../thunderbolt.c:718:23: warning: cast to restricted __le32 .../thunderbolt.c:966:42: warning: incorrect type in assignment (different base types) .../thunderbolt.c:966:42: expected unsigned int [usertype] frame_count .../thunderbolt.c:966:42: got restricted __le32 [usertype] Switch to the bitwise types in the struct thunderbolt_ip_frame_header to reduce this, but not completely solving (9 left), because the same data type is used for Rx header handled locally (in CPU byte order).

self_node_db is a list_head with one entry of struct hsr_node. The purpose is to hold the two MAC addresses of the node itself. It is convenient to recycle the structure. However having a list_head and fetching always the first entry is not really optimal. Created a new data strucure contaning the two MAC addresses named hsr_self_node. Access that structure like an RCU protected pointer so it can be replaced on the fly without blocking the reader. Signed-off-by:

hsr_register_frame_out() compares new sequence_nr vs the old one recorded in hsr_node::seq_out and if the new sequence_nr is higher then it will be written to hsr_node::seq_out as the new value. This operation isn't locked so it is possible that two frames with the same sequence number arrive (via the two slave devices) and are fed to hsr_register_frame_out() at the same time. Both will pass the check and update the sequence counter later to the same value. As a result the content of the same packet is fed into the stack twice. This was noticed by running ping and observing DUP being reported from time to time. Instead of using the hsr_priv::seqnr_lock for the whole receive path (as it is for sending in the master node) add an additional lock that is only used for sequence number checks and updates. Add a per-node lock that is used during sequence number reads and updates. Fixes: f421436a ("net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0)") Signed-off-by:

Sending frames via the hsr (master) device requires a sequence number which is tracked in hsr_priv::sequence_nr and protected by hsr_priv::seqnr_lock. Each time a new frame is sent, it will obtain a new id and then send it via the slave devices. Each time a packet is sent (via hsr_forward_do()) the sequence number is checked via hsr_register_frame_out() to ensure that a frame is not handled twice. This make sense for the receiving side to ensure that the frame is not injected into the stack twice after it has been received from both slave ports. There is no locking to cover the sending path which means the following scenario is possible: CPU0 CPU1 hsr_dev_xmit(skb1) hsr_dev_xmit(skb2) fill_frame_info() fill_frame_info() hsr_fill_frame_info() hsr_fill_frame_info() handle_std_frame() handle_std_frame() skb1's sequence_nr = 1 skb2's sequence_nr = 2 hsr_forward_do() hsr_forward_do() hsr_register_frame_out(, 2) // okay, send) hsr_register_frame_out(, 1) // stop, lower seq duplicate Both skbs (or their struct hsr_frame_info) received an unique id. However since skb2 was sent before skb1, the higher sequence number was recorded in hsr_register_frame_out() and the late arriving skb1 was dropped and never sent. This scenario has been observed in a three node HSR setup, with node1 + node2 having ping and iperf running in parallel. From time to time ping reported a missing packet. Based on tracing that missing ping packet did not leave the system. It might be possible (didn't check) to drop the sequence number check on the sending side. But if the higher sequence number leaves on wire before the lower does and the destination receives them in that order and it will drop the packet with the lower sequence number and never inject into the stack. Therefore it seems the only way is to lock the whole path from obtaining the sequence number and sending via dev_queue_xmit() and assuming the packets leave on wire in the same order (and don't get reordered by the NIC). Cover the whole path for the master interface from obtaining the ID until after it has been forwarded via hsr_forward_skb() to ensure the skbs are sent to the NIC in the order of the assigned sequence numbers.

The hsr device is a software device. Its net_device_ops::ndo_start_xmit() routine will process the packet and then pass the resulting skb to dev_queue_xmit(). During processing, hsr acquires a lock with spin_lock_bh() (hsr_add_node()) which needs to be promoted to the _irq() suffix in order to avoid a potential deadlock. Then there are the warnings in dev_queue_xmit() (due to local_bh_disable() with disabled interrupts) left. Instead trying to address those (there is qdisc and…) for netpoll sake, just disable netpoll on hsr. Disable netpoll on hsr and replace the _irqsave() locking with _bh().

Due to the hashed-MAC optimisation one problem become visible: hsr_handle_sup_frame() walks over the list of available nodes and merges two node entries into one if based on the information in the supervision both MAC addresses belong to one node. The list-walk happens on a RCU protected list and delete operation happens under a lock. If the supervision arrives on both slave interfaces at the same time then this delete operation can occur simultaneously on two CPUs. The result is the first-CPU deletes the from the list and the second CPUs BUGs while attempting to dereference a poisoned list-entry. This happens more likely with the optimisation because a new node for the mac_B entry is created once a packet has been received and removed (merged) once the supervision frame has been received. Avoid removing/ cleaning up a hsr_node twice by adding a `removed' field which is set to true after the removal and checked before the removal.

hsr_forward_skb() a skb and keeps information in an on-stack hsr_frame_info. hsr_get_node() assigns hsr_frame_info::node_src which is from a RCU list. This pointer is used later in hsr_forward_do(). I don't see a reason why this pointer can't vanish midway since there is no guarantee that hsr_forward_skb() is invoked from an RCU read section. Use rcu_read_lock() to protect hsr_frame_info::node_src from its assignment until it is no longer used. Fixes: f266a683 ("net/hsr: Better frame dispatch") Signed-off-by:

The hlist optimisation (which not only uses hlist_head instead of list_head but also splits hsr_priv::node_db into an array of 256 slots) does not consider the "node merge": Upon starting the hsr network (with three nodes) a packet that is sent from node1 to node3 will also be sent from node1 to node2 and then forwarded to node3. As a result node3 will receive 2 packets because it is not able to filter out the duplicate. Each packet received will create a new struct hsr_node with macaddress_A only set the MAC address it received from (the two MAC addesses from node1). At some point (early in the process) two supervision frames will be received from node1. They will be processed by hsr_handle_sup_frame() and one frame will leave early ("Node has already been merged") and does nothing. The other frame will be merged as portB and have its MAC address written to macaddress_B and the hsr_node (that was created for it as macaddress_A) will be removed. From now on HSR is able to identify a duplicate because both packets sent from one node will result in the same struct hsr_node because hsr_get_node() will find the MAC address either on macaddress_A or macaddress_B. Things get tricky with the optimisation: If sender's MAC address is saved as macaddress_A then the lookup will work as usual. If the MAC address has been merged into macaddress_B of another hsr_node then the lookup won't work because it is likely that the data structure is in another bucket. This results in creating a new struct hsr_node and not recognising a possible duplicate. A way around it would be to add another hsr_node::mac_list_B and attach it to the other bucket to ensure that this hsr_node will be looked up either via macaddress_A _or_ macaddress_B. I however prefer to revert it because it sounds like an academic problem rather than real life workload plus it adds complexity. I'm not an HSR expert with what is usual size of a network but I would guess 40 to 60 nodes. With 10.000 nodes and assuming 60us for pass-through (from node to node) then it would take almost 600ms for a packet to almost wrap around which sounds a lot.

Matthieu Baerts says: ==================== mptcp: PM listener events + selftests cleanup Thanks to the patch 6/11, the MPTCP path manager now sends Netlink events when MPTCP listening sockets are created and closed. The reason why it is needed is explained in the linked ticket [1]: MPTCP for Linux, when not using the in-kernel PM, depends on the userspace PM to create extra listening sockets before announcing addresses and ports. Let's call these "PM listeners". With the existing MPTCP netlink events, a userspace PM can create PM listeners at startup time, or in response to an incoming connection. Creating sockets in response to connections is not optimal: ADD_ADDRs can't be sent until the sockets are created and listen()ed, and if all connections are closed then it may not be clear to the userspace PM daemon that PM listener sockets should be cleaned up. Hence this feature request: to add MPTCP netlink events for listening socket close & create, so PM listening sockets can be managed based on application activity. [1] https://github.com/multipath-tcp/mptcp_net-next/issues/313 Selftests for these new Netlink events have been added in patches 9,11/11. The remaining patches introduce different cleanups and small improvements in MPTCP selftests to ease the maintenance and the addition of new tests. ==================== Link: https://lore.kernel.org/r/20221130140637.409926-1-matthieu.baerts@tessares.netSigned-off-by:

This patch adds two new MPTCP netlink event types for PM listening socket create and close, named MPTCP_EVENT_LISTENER_CREATED and MPTCP_EVENT_LISTENER_CLOSED. Add a new function mptcp_event_pm_listener() to push the new events with family, port and addr to userspace. Invoke mptcp_event_pm_listener() with MPTCP_EVENT_LISTENER_CREATED in mptcp_listen() and mptcp_pm_nl_create_listen_socket(), invoke it with MPTCP_EVENT_LISTENER_CLOSED in __mptcp_close_ssk().

Just to avoid classical Bash pitfall where variables are accidentally overridden by other functions because the proper scope has not been defined. That's also what is done in other MPTCP selftests scripts where all non local variables are defined at the beginning of the script and the others are defined with the "local" keyword. Reviewed-by:

It is clearer to declare these global variables at the beginning of the file as it is done in other MPTCP selftests rather than in functions in the middle of the script. So for uniformity reason, we can do the same here in mptcp_sockopt.sh. Suggested-by:

The definition of 'rndh' was probably copied from one script to another but some times, 'sec' was not defined, not used and/or not spelled properly. Here all the 'rndh' are now defined the same way. Reviewed-by:

Some variables were set but never used. This was not causing any issues except adding some confusion and having shellcheck complaining about them. Reviewed-by:

A new "sandbox" net namespace is available where no other netfilter rules have been added. Use this new netns instead of re-using "ns1" and clean it. Reviewed-by:

I must have missed that these stats are only exposed via the unstructured ethtool -S when they got merged. Plumb in the structured form. Reviewed-by:

Arınç ÜNAL says: ==================== remove label = "cpu" from DSA dt-binding With this patch series, we're completely getting rid of 'label = "cpu";' which is not used by the DSA dt-binding at all. Information for taking the patches for maintainers: Patch 1: netdev maintainers (based off netdev/net-next.git main) Patch 2-3: SoC maintainers (based off soc/soc.git soc/dt) Patch 4: MIPS maintainers (based off mips/linux.git mips-next) Patch 5: PowerPC maintainers (based off powerpc/linux.git next-test) I've been meaning to submit this for a few months. Find the relevant conversation here: https://lore.kernel.org/netdev/20220913155408.GA3802998-robh@kernel.org/ Here's how I did it, for the interested (or suggestions): Find the platforms which have got 'label = "cpu";' defined. grep -rnw . -e 'label = "cpu";' Remove the line where 'label = "cpu";' is included. sed -i /'label = "cpu";'/,+d arch/arm/boot/dts/* sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/freescale/* sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/marvell/* sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/mediatek/* sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/rockchip/* sed -i /'label = "cpu";'/,+d arch/mips/boot/dts/qca/* sed -i /'label = "cpu";'/,+d arch/mips/boot/dts/ralink/* sed -i /'label = "cpu";'/,+d arch/powerpc/boot/dts/turris1x.dts sed -i /'label = "cpu";'/,+d Documentation/devicetree/bindings/net/qca,ar71xx.yaml Restore the symlink files which typechange after running sed. ==================== Link: https://lore.kernel.org/r/20221130141040.32447-1-arinc.unal@arinc9.comSigned-off-by:
