The widely used open source firmware candleLight supports padding the USB packets to max packet size to improve performance on Windows systems. This patch documents the bit.

The widely used open source firmware candleLight has optional support for reading/writing of an user defined value into the device's flash. This is indicated by the GS_CAN_FEATURE_USER_ID feature. The corresponding request are GS_USB_BREQ_GET_USER_ID and GS_USB_BREQ_SET_USER_ID. This patch documents these values.

In the binary interface a feature bit might have a corresponding mode bit (of the same value). The GS_CAN_FEATURE_IDENTIFY feature doesn't come with a mode. Document this, to avoid gaps when adding more features/modes later. Link: https://lore.kernel.org/all/20220309124132.291861-10-mkl@pengutronix.deSigned-off-by:

Newer versions of the widely used open source firmware candleLight support hardware timestamps. The support is activated by setting the GS_CAN_MODE_HW_TIMESTAMP in the GS_USB_BREQ_MODE request. Although timestamp support is not yet supported by this driver, add the missing bit for documentation purpose.

Adds support for the CANFD IP variant in the V3U SoC. Differences to controllers in other SoCs are limited to an increase in the number of channels from two to eight, an absence of dedicated registers for "classic" CAN mode, and a number of differences in magic numbers (register offsets and layouts). Inspired by BSP patch by Kazuya Mizuguchi. Link: https://lore.kernel.org/all/20220309162609.3726306-2-uli+renesas@fpond.euSigned-off-by:

can: etas_es58x: es58x_fd_rx_event_msg(): initialize rx_event_msg before calling es58x_check_msg_len() Function es58x_fd_rx_event() invokes the es58x_check_msg_len() macro: | ret = es58x_check_msg_len(es58x_dev->dev, *rx_event_msg, msg_len); While doing so, it dereferences an uninitialized variable: *rx_event_msg. This is actually harmless because es58x_check_msg_len() only uses preprocessor macros (sizeof() and __stringify()) on *rx_event_msg. c.f. [1].

The vxcan driver provides a pair of virtual CAN interfaces to exchange CAN traffic between different namespaces - analogue to veth. In opposite to the vcan driver the local sent CAN traffic on this interface is not echo'ed back but only sent to the remote peer. This is unusual and can be easily fixed by removing IFF_ECHO from the netdevice flags that are set for vxcan interfaces by default at startup. Without IFF_ECHO set on driver level, the local sent CAN frames are echo'ed in af_can.c in can_send(). This patch makes vxcan interfaces adopt the same local echo behavior and procedures as known from the vcan interfaces.

With can_create_echo_skb() the skb which is forwarded to the peer CAN interface shares the sk pointer from the originating socket. This makes the CAN frame show up in the peer namespace as a TX packet. With the use of skb_clone() analogue to the handling in gw.c the peer skb gets a new start in the peer namespace and correctly appears as a RX packet.

The reason to extend the max PDU size from 4095 Byte (12 bit length value) to a 32 bit value (up to 4 GByte) was to be able to flash 64 kByte bootloaders with a single ISO-TP PDU. The max PDU size in the Linux kernel implementation was set to 8200 Bytes to be able to test the length information escape sequence. It turns out that the demand for 64 kByte PDUs is real so the value for MAX_MSG_LENGTH is set to 66000 to be able to potentially add some checksums to the 65.536 Byte block.

The N_As value describes the time a CAN frame needs on the wire when transmitted by the CAN controller. Even very short CAN FD frames need arround 100 usecs (bitrate 1Mbit/s, data bitrate 8Mbit/s). Having N_As to be zero (the former default) leads to 'no CAN frame separation' when STmin is set to zero by the receiving node. This 'burst mode' should not be enabled by default as it could potentially dump a high number of CAN frames into the netdev queue from the soft hrtimer context. This does not affect the system stability but is just not nice and cooperative. With this N_As/frame_txtime value the 'burst mode' is disabled by default. As user space applications usually do not set the frame_txtime element of struct can_isotp_options the new in-kernel default is very likely overwritten with zero when the sockopt() CAN_ISOTP_OPTS is invoked. To make sure that a N_As value of zero is only set intentional the value '0' is now interpreted as 'do not change the current value'. When a frame_txtime of zero is required for testing purposes this CAN_ISOTP_FRAME_TXTIME_ZERO u32 value has to be set in frame_txtime.

Instead of dumping the CAN frames into the netdevice queue the process to transmit consecutive frames (CF) now waits for the frame to be transmitted and therefore echo'ed from the CAN interface. Link: https://lore.kernel.org/all/20220309120416.83514-1-socketcan@hartkopp.netSigned-off-by:

Back when tcp_tso_autosize() and TCP pacing were introduced, our focus was really to reduce burst sizes for long distance flows. The simple heuristic of using sk_pacing_rate/1024 has worked well, but can lead to too small packets for hosts in the same rack/cluster, when thousands of flows compete for the bottleneck. Neal Cardwell had the idea of making the TSO burst size a function of both sk_pacing_rate and tcp_min_rtt() Indeed, for local flows, sending bigger bursts is better to reduce cpu costs, as occasional losses can be repaired quite fast. This patch is based on Neal Cardwell implementation done more than two years ago. bbr is adjusting max_pacing_rate based on measured bandwidth, while cubic would over estimate max_pacing_rate. /proc/sys/net/ipv4/tcp_tso_rtt_log can be used to tune or disable this new feature, in logarithmic steps. Tested: 100Gbit NIC, two hosts in the same rack, 4K MTU. 600 flows rate-limited to 20000000 bytes per second.

tcp_should_autocork() is evaluating if it makes senses to not immediately send current skb, hoping that user space will add more payload on it by the time TCP stack reacts to upcoming TX completions. If current skb got MSG_EOR mark, then we know that no further data will be added, it is therefore futile to wait. SOF_TIMESTAMPING_TX_ACK will become a bit more accurate, if prior packets are still in qdisc/device queues. Signed-off-by:

Dimitris Michailidis says: ==================== net/fungible: fix errors when CONFIG_TLS_DEVICE=n This pair of patches fix compile errors in funeth when CONFIG_TLS_DEVICE=n. The errors are due to symbols that are not defined in this config but are used in code guarded by "if (IS_ENABLED(CONFIG_TLS_DEVICE) ..." One option is to place this code under preprocessor guards that will keep the compiler from looking at the code. The option adopted here is to define the offending symbols also when CONFIG_TLS_DEVICE=n. The first patch does this for two functions in tls.h. The second does the same for driver symbols and makes tls.h inclusion unconditional. ==================== Link: https://lore.kernel.org/r/20220309034032.405212-1-dmichail@fungible.comSigned-off-by:

This chips supports two ways to configure max MTU size: - by setting SW_LEGAL_PACKET_DISABLE bit: if this bit is 0 allowed packed size will be between 64 and bytes 1518. If this bit is 1, it will accept packets up to 2000 bytes. - by setting SW_JUMBO_PACKET bit. If this bit is set, the chip will ignore SW_LEGAL_PACKET_DISABLE value and use REG_SW_MTU__2 register to configure MTU size. Current driver has disabled SW_JUMBO_PACKET bit and activates SW_LEGAL_PACKET_DISABLE. So the switch will pass all packets up to 2000 without any way to configure it. By providing port_change_mtu we are switch to SW_JUMBO_PACKET way and will be able to configure MTU up to ~9000. Signed-off-by:

Commit 429c83c7 ("dt-bindings: net: dsa: realtek: convert to YAML schema, add MDIO") converts realtek-smi.txt to realtek.yaml, but missed to adjust its reference in MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Repair this file reference in REALTEK RTL83xx SMI DSA ROUTER CHIPS. Signed-off-by:

The registers used to inject a frame to one of the ports is shared between all the net devices. Therefore, there can be race conditions for accessing the registers when two processes send frames at the same time on different ports. To fix this, add a spinlock around the function 'lan966x_port_ifh_xmit()'. Signed-off-by:

Stephen Rothwell reported the following failure on powerpc: ERROR: modpost: ".local_memory_node" [drivers/net/ethernet/fungible/funeth/funeth.ko] undefined! AFAICS this is because local_memory_node() is a non-inline non-exported function when CONFIG_HAVE_MEMORYLESS_NODES=y. It is also the wrong API to get a CPU's memory node. Use cpu_to_mem() in the two spots it's used. Fixes: ee6373dd ("net/funeth: probing and netdev ops") Fixes: db37bc17 ("net/funeth: add the data path") Reported-by:
