Move the NETIF_F_RX_UDP_TUNNEL_PORT feature check into udp_tunnel_nic_*_port() helpers, since they're always done right before the call. Add similar checks before calling the notifier. udp_tunnel_nic invokes the notifier without checking features which could result in some wasted cycles.

2021-01-07Merge branch 'bcm63xx_enet-major-makeover-of-driver'Jakub Kicinski
Sieng Piaw Liew says: ==================== bcm63xx_enet: major makeover of driver This patch series aim to improve the bcm63xx_enet driver by integrating the latest networking features, i.e. batched rx processing, BQL, build_skb, etc. The newer enetsw SoCs are found to be able to do unaligned rx DMA by adding NET_IP_ALIGN padding which, combined with these patches, improved packet processing performance by ~50% on BCM6328. Older non-enetsw SoCs still benefit mainly from rx batching. Performance improvement of ~30% is observed on BCM6333. The BCM63xx SoCs are designed for routers. As such, having BQL is beneficial as well as trivial to add. v3: * Simplify xmit_more patch by not moving around the code needlessly. * Fix indentation in xmit_more patch. * Fix indentation in build_skb patch. * Split rx ring cleanup patch from build_skb patch and precede build_skb patch for better understanding, as suggested by Florian Fainelli. v2: * Add xmit_more support and rx loop improvisation patches. * Moved BQL netdev_reset_queue() to bcm_enet_stop()/bcm_enetsw_stop() functions as suggested by Florian Fainelli. * Improved commit messages. ==================== Link: https://lore.kernel.org/r/20210106144208.1935-1-liew.s.piaw@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-01-07bcm63xx_enet: convert to build_skbSieng Piaw Liew
We can increase the efficiency of rx path by using buffers to receive packets then build SKBs around them just before passing into the network stack. In contrast, preallocating SKBs too early reduces CPU cache efficiency. Check if we're in NAPI context when refilling RX. Normally we're almost always running in NAPI context. Dispatch to napi_alloc_frag directly instead of relying on netdev_alloc_frag which does the same but with the overhead of local_bh_disable/enable. Tested on BCM6328 320 MHz and iperf3 -M 512 to measure packet/sec performance. Included netif_receive_skb_list and NET_IP_ALIGN optimizations.

2021-01-07qmi_wwan: Increase headroom for QMAP SKBsKristian Evensen
When measuring the throughput (iperf3 + TCP) while routing on a not-so-powerful device (Mediatek MT7621, 880MHz CPU), I noticed that I achieved significantly lower speeds with QMI-based modems than for example a USB LAN dongle. The CPU was saturated in all of my tests. With the dongle I got ~300 Mbit/s, while I only measured ~200 Mbit/s with the modems. All offloads, etc. were switched off for the dongle, and I configured the modems to use QMAP (16k aggregation). The tests with the dongle were performed in my local (gigabit) network, while the LTE network the modems were connected to delivers 700-800 Mbit/s. Profiling the kernel revealed the cause of the performance difference. In qmimux_rx_fixup(), an SKB is allocated for each packet contained in the URB. This SKB has too little headroom, causing the check in skb_cow() (called from ip_forward()) to fail. pskb_expand_head() is then called and the SKB is reallocated. In the output from perf, I see that a significant amount of time is spent in pskb_expand_head() + support functions. In order to ensure that the SKB has enough headroom, this commit increases the amount of memory allocated in qmimux_rx_fixup() by LL_MAX_HEADER. The reason for using LL_MAX_HEADER and not a more accurate value, is that we do not know the type of the outgoing network interface. After making this change, I achieve the same throughput with the modems as with the dongle.

The System Controller Firmware (SCFW) is a low-level system function which runs on a dedicated Cortex-M core to provide power, clock, and resource management. It exists on some i.MX8 processors. e.g. i.MX8QM (QM, QP), and i.MX8QX (QXP, DX). SCU driver manages the IPC interface between host CPU and the SCU firmware running on M4. For i.MX8QM, stop mode request is controlled by System Controller Unit(SCU) firmware, this patch introduces FLEXCAN_QUIRK_SETUP_STOP_MODE_SCFW quirk for this function.

2021-01-06can: raw: return -ERANGE when filterset does not fit into user space bufferOliver Hartkopp
Multiple filters (struct can_filter) can be set with the setsockopt() function, which was originally intended as a write-only operation. As getsockopt() also provides a CAN_RAW_FILTER option to read back the given filters, the caller has to provide an appropriate user space buffer. In the case this buffer is too small the getsockopt() silently truncates the filter information and gives no information about the needed space. This is safe but not convenient for the programmer. In net/core/sock.c the SO_PEERGROUPS sockopt had a similar requirement and solved it by returning -ERANGE in the case that the provided data does not fit into the given user space buffer and fills the required size into optlen, so that the caller can retry with a matching buffer length. This patch adopts this approach for CAN_RAW_FILTER getsockopt().

2021-01-06can: tcan4x5x: rework SPI accessMarc Kleine-Budde
This patch reworks the SPI access and fixes several probems: - tcan4x5x_regmap_gather_write(), tcan4x5x_regmap_read(): Do not place variable "addr" on stack and use it as buffer for SPI transfer. Buffers for SPI transfers must be allocated from DMA save memory. - tcan4x5x_regmap_gather_write(), tcan4x5x_regmap_read(): Halfe number of SPI transfers by using a single buffer + memcpy(). This improves the performance, especially on SPI controllers, which use interrupt based transfers. - Use "8" bits per word, not "32". This makes it possible to use this driver on SoCs like the Raspberry Pi, which SPI host controller drivers only support 8 bits per word. Note: this breaks half duplex only controllers. Support for them will be re-added in the next patch.

The KS8851 has a reduced internal PHY, which is accessible through its registers at offset 0xe4. The PHY is compatible with KS886x PHY present in Micrel switches, except the PHY ID Low/High registers are swapped. Register MDIO bus so this PHY can be detected and probed by phylib.

2021-01-05octeontx2-pf: Add RSS multi group supportGeetha sowjanya
Hardware supports 8 RSS groups per interface. Currently we are using only group '0'. This patch allows user to create new RSS groups/contexts and use the same as destination for flow steering rules. usage: To steer the traffic to RQ 2,3 ethtool -X eth0 weight 0 0 1 1 context new (It will print the allocated context id number) New RSS context is 1 ethtool -N eth0 flow-type tcp4 dst-port 80 context 1 loc 1 To delete the context ethtool -X eth0 context 1 delete When an RSS context is removed, the active classification rules using this context are also removed. Change-log: v4 - Fixed compiletime warning. - Address Saeed's comments on v3. v3 - Coverted otx2_set_rxfh() to use new function. v2 - Removed unrelated whitespace - Coverted otx2_get_rxfh() to use new function.

2021-01-05net: nfc: nci: Change the NCI close sequenceBongsu Jeon
If there is a NCI command in work queue after closing the NCI device at nci_unregister_device, The NCI command timer starts at flush_workqueue function and then NCI command timeout handler would be called 5 second after flushing the NCI command work queue and destroying the queue. At that time, the timeout handler would try to use NCI command work queue that is destroyed already. it will causes the problem. To avoid this abnormal situation, change the sequence to prevent the NCI command timeout handler from being called after destroying the NCI command work queue.

2021-01-05net: kcm: Replace fput with sockfd_putZheng Yongjun
The function sockfd_lookup uses fget on the value that is stored in the file field of the returned structure, so fput should ultimately be applied to this value. This can be done directly, but it seems better to use the specific macro sockfd_put, which does the same thing. Perform a source code refactoring by using the following semantic patch. // <smpl> @@ expression s; @@ s = sockfd_lookup(...) ... + sockfd_put(s); - fput(s->file); // </smpl> Signed-off-by: Zheng Yongjun <zhengyongjun3@huawei.com> Signed-off-by: David S.

It adds a struct of device specific callbacks for STE layer below dr_ste. Each device will implement its HW-specific function, and a common logic from the DR code will access these functions through the new ste_ctx API. Connect-X5-style steering format is called STE_v0. In the next patch series we bring the Connect-X6-style format - STE_v1. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
