2024-06-21net: ethernet: rtsn: Add support for Renesas Ethernet-TSNNiklas Söderlund4-0/+1867
Add initial support for Renesas Ethernet-TSN End-station device of R-Car V4H. The Ethernet End-station can connect to an Ethernet network using a 10 Mbps, 100 Mbps, or 1 Gbps full-duplex link via MII/GMII/RMII/RGMII. Depending on the connected PHY. The driver supports Rx checksum and offload and hardware timestamps. While full power management and suspend/resume is not yet supported the driver enables runtime PM in order to enable the module clock. While explicit clock management using clk_enable() would suffice for the supported SoC, the module could be reused on SoCs where the module is part of a power domain.

2024-06-21net: dsa: qca8k: factor out bridge join/leave logicMatthias Schiffer1-51/+50
Most of the logic in qca8k_port_bridge_join() and qca8k_port_bridge_leave() is the same. Refactor to reduce duplication and prepare for reusing the code for implementing bridge port isolation. dsa_port_offloads_bridge_dev() is used instead of dsa_port_offloads_bridge(), passing the bridge in as a struct netdevice *, as we won't have a struct dsa_bridge in qca8k_port_bridge_flags(). The error handling is changed slightly in the bridge leave case, returning early and emitting an error message when a regmap access fails. This shouldn't matter in practice, as there isn't much we can do if communication with the switch breaks down in the middle of reconfiguration.

2024-06-21net: dsa: qca8k: do not write port mask twice in bridge join/leaveMatthias Schiffer1-2/+5
qca8k_port_bridge_join() set QCA8K_PORT_LOOKUP_CTRL() for i == port twice, once in the loop handling all other port's masks, and finally at the end with the accumulated port_mask. The first time it would incorrectly set the port's own bit in the mask, only to correct the mistake a moment later. qca8k_port_bridge_leave() had the same issue, but here the regmap_clear_bits() was a no-op rather than setting an unintended value. Remove the duplicate assignment by skipping the whole loop iteration for i == port. The unintended bit setting doesn't seem to have any negative effects (even when not reverted right away), so the change is submitted as a simple cleanup rather than a fix.

2024-06-21ionic: fix kernel panic due to multi-buffer handlingTaehee Yoo1-9/+18
Currently, the ionic_run_xdp() doesn't handle multi-buffer packets properly for XDP_TX and XDP_REDIRECT. When a jumbo frame is received, the ionic_run_xdp() first makes xdp frame with all necessary pages in the rx descriptor. And if the action is either XDP_TX or XDP_REDIRECT, it should unmap dma-mapping and reset page pointer to NULL for all pages, not only the first page. But it doesn't for SG pages. So, SG pages unexpectedly will be reused. It eventually causes kernel panic.

The __ethtool_get_ts_info function returns directly if the device has a get_ts_info() method. For bonding with an active slave, this works correctly as we simply return the real device's timestamping information. However, when there is no active slave, we only check the slave's TX software timestamp information. We still need to set the phc index and RX timestamp information manually. Otherwise, the result will be look like: Time stamping parameters for bond0: Capabilities: software-transmit PTP Hardware Clock: 0 Hardware Transmit Timestamp Modes: none Hardware Receive Filter Modes: none This issue does not affect VLAN or MACVLAN devices, as they only have one downlink and can directly use the downlink's timestamping information.

2024-06-21net: dsa: ksz_common: Allow only up to two HSR HW offloaded ports for KSZ9477Lukasz Majewski1-0/+7
The KSZ9477 allows HSR in-HW offloading for any of two selected ports. This patch adds check if one tries to use more than two ports with HSR offloading enabled. The problem is with RedBox configuration (HSR-SAN) - when configuring: ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 interlink lan3 \ supervision 45 version 1 The lan1 (port0) and lan2 (port1) are correctly configured as ports, which can use HSR offloading on ksz9477. However, when we do already have two bits set in hsr_ports, we need to return (-ENOTSUPP), so the interlink port (lan3) would be used with SW based HSR RedBox support. Otherwise, I do see some strange network behavior, as some HSR frames are visible on non-HSR network and vice versa. This causes the switch connected to interlink port (lan3) to drop frames and no communication is possible. Moreover, conceptually - the interlink (i.e. HSR-SAN port - lan3/port2) shall be only supported in software as it is also possible to use ksz9477 with only SW based HSR (i.e. port0/1 -> hsr0 with offloading, port2 -> HSR-SAN/interlink, port4/5 -> hsr1 with SW based HSR).

2024-06-21bnxt_en: implement netdev_queue_mgmt_opsDavid Wei1-0/+275
Implement netdev_queue_mgmt_ops for bnxt added in [1]. Two bnxt_rx_ring_info structs are allocated to hold the new/old queue memory. Queue memory is copied from/to the main bp->rx_ring[idx] bnxt_rx_ring_info. Queue memory is pre-allocated in bnxt_queue_mem_alloc() into a clone, and then copied into bp->rx_ring[idx] in bnxt_queue_mem_start(). Similarly, when bp->rx_ring[idx] is stopped its queue memory is copied into a clone, and then freed later in bnxt_queue_mem_free(). I tested this patchset with netdev_rx_queue_restart(), including inducing errors in all places that returns an error code. In all cases, the queue is left in a good working state. Rx queues are created/destroyed using bnxt_hwrm_rx_ring_alloc() and bnxt_hwrm_rx_ring_free(), which issue HWRM_RING_ALLOC and HWRM_RING_FREE commands respectively to the firmware. By the time a HWRM_RING_FREE response is received, there won't be any more completions from that queue. Thanks to Somnath for helping me with this patch.

When the mcp251xfd_start_xmit() function fails, the driver stops processing messages, and the interrupt routine does not return, running indefinitely even after killing the running application. Error messages: [ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16 [ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty.

And there is concurrent access to the bus. The problem occurs because tx_ring->head increments even if mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX package while still expecting a response in mcp251xfd_handle_tefif_one(). Resolve the issue by starting a workqueue to write the tx obj synchronously if err = -EBUSY. In case of another error, decrement tx_ring->head, remove skb from the echo stack, and drop the message.

2024-06-21can: m_can: don't enable transceiver when probingMartin Hundebøll2-66/+116
The m_can driver sets and clears the CCCR.INIT bit during probe (both when testing the NON-ISO bit, and when configuring the chip). After clearing the CCCR.INIT bit, the transceiver enters normal mode, where it affects the CAN bus (i.e. it ACKs frames). This can cause troubles when the m_can node is only used for monitoring the bus, as one cannot setup listen-only mode before the device is probed. Rework the probe flow, so that the CCCR.INIT bit is only cleared when upping the device. First, the tcan4x5x driver is changed to stay in standby mode during/after probe. This in turn requires changes when setting bits in the CCCR register, as its CSR and CSA bits are always high in standby mode.

2024-06-21net: dsa: microchip: fix initial port flush problemTristram Ha1-4/+2
The very first flush in any port will flush all learned addresses in all ports. This can be observed by unplugging the cable from one port while additional ports are connected and dumping the fdb entries. This problem is caused by the initially wrong value programmed to the REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit takes effect and flushes all learned entries. After that call both bits are reset and so the next port flush will not cause such problem again.

2024-06-21wifi: mt76: un-embedd netdev from mt76_devBreno Leitao12-21/+49
Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_devices from struct mt76_dev by converting them into pointers, and allocating them dynamically. Use the leverage alloc_netdev_dummy() to allocate the net_device object at mt76_dma_init(). The free of the device occurs at mt76_dma_cleanup().

The current code only restores PTP tx_avail count when we get DMA mapping errors. Fix it so that the PTP tx_avail count will be restored for both DMA mapping errors and skb_pad() errors. Otherwise PTP TX timestamp will not be available after a PTP packet hits the skb_pad() error.
