The kernel calls ndo_set_rx_mode() callback supplying it will all necessary info, such as device state flags, multicast mac addresses list and so on. Since we have only 128 bits to communicate with PF we need to initiate several requests to PF with small/short operation each based on input data. So this commit implements following PF messages codes along with new data structures for them: NIC_MBOX_MSG_RESET_XCAST to flush all filters configured for this particular network interface (VF) NIC_MBOX_MSG_ADD_MCAST to add new MAC address to DMAC filter registers for this particular network interface (VF) NIC_MBOX_MSG_SET_XCAST to apply filtering configuration to filter control register Signed-off-by: NVadim Lomovtsev <Vadim.Lomovtsev@cavium.com> Signed-off-by: NDavid S.

The ThunderX NIC could be partitioned to up to 128 VFs and thus represented to system. Each VF is mapped to pair BGX:LMAC, and each of VF is configured by kernel individually. Eventually the bunch of VFs could be mapped onto same pair BGX:LMAC and thus could cause several multicast filtering configuration requests to LMAC with the same MAC addresses. This commit is to add ThunderX NIC BGX filtering manipulation routines. Signed-off-by: NVadim Lomovtsev <Vadim.Lomovtsev@cavium.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The ThunderX NIC has two Ethernet Interfaces (BGX) each of them could has up to four Logical MACs configured. Each of BGX has 32 filters to be configured for filtering ingress packets. The number of filters available to particular LMAC is from 8 (if we have four LMACs configured per BGX) up to 32 (in case of only one LMAC is configured per BGX). At the same time the NIC could present up to 128 VFs to OS as network interfaces, each of them kernel will configure with set of MAC addresses for filtering. So to prevent dupes in BGX filter registers from different network interfaces it is required to cache and track all filter configuration requests prior to applying them onto BGX filter registers. This commit is to update LMAC structures with control fields to allocate/releasing filters tracking list along with implementing dmac array allocate/release per LMAC.

The ThunderX NIC has set of registers which allows to configure filter policy for ingress packets. There are three possible regimes of filtering multicasts, broadcasts and unicasts: accept all, reject all and accept filter allowed only. Current implementation has enum with all of them and two generic macro for enabling filtering et all (CAM_ACCEPT) and enabling/disabling broadcast packets, which also should be corrected in order to represent register bits properly. All these values are private for driver and there is no need to ‘publish’ them via header file. This commit is to move filtering register manipulation values from header file into source with explicit assignment of exact register values to them to be used while register configuring.

Martin Blumenstingl says: ==================== Meson8m2 support for dwmac-meson8b The Meson8m2 SoC is an updated version of the Meson8 SoC. Some of the peripherals are shared with Meson8b (for example the watchdog registers and the internal temperature sensor calibration procedure). Meson8m2 also seems to include the same Gigabit MAC register layout as Meson8b. The registers in the Amlogic dwmac "glue" seem identical between Meson8b and Meson8m2. Manual testing seems to confirm this. To be extra-safe a new compatible string is added because there's no (public) documentation on the Meson8m2 SoC.

This commit has fix for RX traffic issues when we stress test the driver with continuous ifconfig up/down under very high traffic conditions. Reason for the issue is that, in existing liquidio_stop function NAPI is disabled even before actual FW/HW interface is brought down via send_rx_ctrl_cmd(lio, 0). Between time frame of NAPI disable and actual interface down in firmware, firmware continuously enqueues rx traffic to host. When interrupt happens for new packets, host irq handler fails in scheduling NAPI as the NAPI is already disabled. After "ifconfig <iface> up", Host re-enables NAPI but cannot schedule it until it receives another Rx interrupt. Host never receives Rx interrupt as it never cleared the Rx interrupt it received during interface down operation. NIC Rx interrupt gets cleared only when Host processes queue and clears the queue counts. Above anomaly leads to other issues like packet overflow in FW/HW queues, backpressure. Fix: This commit fixes this issue by disabling NAPI only after informing firmware to stop queueing packets to host via send_rx_ctrl_cmd(lio, 0). send_rx_ctrl_cmd is not visible in the patch as it is already there in the code. The DOWN command also waits for any pending packets to be processed by NAPI so that the deadlock will not occur.

Kirill Tkhai says: ==================== Close race between {un, }register_netdevice_notifier and pernet_operations the problem is {,un}register_netdevice_notifier() do not take pernet_ops_rwsem, and they don't see network namespaces, being initialized in setup_net() and cleanup_net(), since at this time net is not hashed to net_namespace_list. This may lead to imbalance, when a notifier is called at time of setup_net()/net is alive, but it's not called at time of cleanup_net(), for the devices, hashed to the net, and vise versa. See (3/3) for the scheme of imbalance. This patchset fixes the problem by acquiring pernet_ops_rwsem at the time of {,un}register_netdevice_notifier() (3/3). (1-2/3) are preparations in xfrm and netfilter subsystems. The problem was introduced a long ago, but backporting won't be easy, since every previous kernel version may have changes in netdevice notifiers, and they all need review and testing. Otherwise, there may be more pernet_operations, which register or unregister netdevice notifiers, and that leads to deadlock (which is was fixed in 1-2/3).

{un,}register_netdevice_notifier() iterate over all net namespaces hashed to net_namespace_list. But pernet_operations register and unregister netdevices in unhashed net namespace, and they are not seen for netdevice notifiers. This results in asymmetry: 1)Race with register_netdevice_notifier() pernet_operations::init(net) ... register_netdevice() ... call_netdevice_notifiers() ... ... nb is not called ... ... register_netdevice_notifier(nb) -> net skipped ... ... list_add_tail(&net->list, ..) ... Then, userspace stops using net, and it's destructed: pernet_operations::exit(net) unregister_netdevice() call_netdevice_notifiers() ... nb is called ... This always happens with net::loopback_dev, but it may be not the only device. 2)Race with unregister_netdevice_notifier() pernet_operations::init(net) register_netdevice() call_netdevice_notifiers() ... nb is called ... Then, userspace stops using net, and it's destructed: list_del_rcu(&net->list) ... pernet_operations::exit(net) unregister_netdevice_notifier(nb) -> net skipped dev_change_net_namespace() ... call_netdevice_notifiers() ... nb is not called ... unregister_netdevice() call_netdevice_notifiers() ... nb is not called ... This race is more danger, since dev_change_net_namespace() moves real network devices, which use not trivial netdevice notifiers, and if this will happen, the system will be left in unpredictable state. The patch closes the race. During the testing I found two places, where register_netdevice_notifier() is called from pernet init/exit methods (which led to deadlock) and fixed them (see previous patches). The review moved me to one more unusual registration place: raw_init() (can driver). It may be a reason of problems, if someone creates in-kernel CAN_RAW sockets, since they will be destroyed in exit method and raw_release() will call unregister_netdevice_notifier(). But grep over kernel tree does not show, someone creates such sockets from kernel space. Theoretically, there can be more places like this, and which are hidden from review, but we found them on the first bumping there (since there is no a race, it will be 100% reproducible).

Trigger a port mod message to request an MTU change on the NIC when any physical port representor is assigned a new MTU value. The driver waits 10 msec for an ack that the FW has set the MTU. If no ack is received the request is rejected and an appropriate warning flagged. Rather than maintain an MTU queue per repr, one is maintained per app. Because the MTU ndo is protected by the rtnl lock, there can never be contention here. Portmod messages from the NIC are also protected by rtnl so we first check if the portmod is an ack and, if so, handle outside rtnl and the cmsg work queue. Acks are detected by the marking of a bit in a portmod response. They are then verfied by checking the port number and MTU value expected by the app. If the expected MTU is 0 then no acks are currently expected. Also, ensure that the packet headroom reserved by the flower firmware is considered when accepting an MTU change on any repr.

There were a number of issues with setting the RX coalescing parameters: - we would not be preserving values that would have been configured across close/open calls, instead we would always reset to no timeout and 1 interrupt per packet, this would also prevent DIM from setting its default usec/pkts values - when adaptive RX would be turned on, we woud not be fetching the default parameters, we would stay with no timeout/1 packet per interrupt until the estimator kicks in and changes that - finally disabling adaptive RX coalescing while providing parameters would not be honored, and we would stay with whatever DIM had previously determined instead of the user requested parameters Fixes: b6e0e875 ("net: systemport: Implement adaptive interrupt coalescing") Signed-off-by: NFlorian Fainelli <f.fainelli@gmail.com> Reviewed-by: NTal Gilboa <talgi@mellanox.com> Signed-off-by: NDavid S.

Adaptive TX coalescing is not currently giving us any advantages and ends up making the CPU spin more frequently until TX completion. Deny and disable adaptive TX coalescing for now and rely on static configuration, we can always add it back later.

NETIF_F_HW_VLAN_[CS]TAG_FILTER features require more than just a bit flip in dev->features in order to keep the driver in a consistent state. These features notify the driver of each added/removed vlan, but toggling of vlan-filter does not notify the driver accordingly for each of the existing vlans. This patch implements a similar solution to NETIF_F_RX_UDP_TUNNEL_PORT behavior (which notifies the driver about UDP ports in the same manner that vids are reported). Each toggling of the features propagates to the 8021q module, which iterates over the vlans and call add/kill ndo accordingly.
