git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Wrap datapath globals into net_aligned_data, to avoid false sharing - Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container) - Add SO_INQ and SCM_INQ support to AF_UNIX - Add SIOCINQ support to AF_VSOCK - Add TCP_MAXSEG sockopt to MPTCP - Add IPv6 force_forwarding sysctl to enable forwarding per interface - Make TCP validation of whether packet fully fits in the receive window and the rcv_buf more strict. With increased use of HW aggregation a single "packet" can be multiple 100s of kB - Add MSG_MORE flag to optimize large TCP transmissions via sockmap, improves latency up to 33% for sockmap users - Convert TCP send queue handling from tasklet to BH workque - Improve BPF iteration over TCP sockets to see each socket exactly once - Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code - Support enabling kernel threads for NAPI processing on per-NAPI instance basis rather than a whole device. Fully stop the kernel NAPI thread when threaded NAPI gets disabled. Previously thread would stick around until ifdown due to tricky synchronization - Allow multicast routing to take effect on locally-generated packets - Add output interface argument for End.X in segment routing - MCTP: add support for gateway routing, improve bind() handling - Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink - Add a new neighbor flag ("extern_valid"), which cedes refresh responsibilities to userspace.

2025-07-01time/timecounter: Fix the lie that struct cyclecounter is constGreg Kroah-Hartman
In both the read callback for struct cyclecounter, and in struct timecounter, struct cyclecounter is declared as a const pointer. Unfortunatly, a number of users of this pointer treat it as a non-const pointer as it is burried in a larger structure that is heavily modified by the callback function when accessed. This lie had been hidden by the fact that container_of() "casts away" a const attribute of a pointer without any compiler warning happening at all. Fix this all up by removing the const attribute in the needed places so that everyone can see that the structure really isn't const, but can, and is, modified by the users of it.

This is a preparation patch for the introduction of CAN XL. CAN FD and CAN XL uses similar bittiming parameters. Add one level of nesting for all the CAN FD parameters. Typically: priv->can.data_bittiming; becomes: priv->can.fd.data_bittiming; This way, the CAN XL equivalent (to be introduced later) would be: priv->can.xl.data_bittiming; Add the new struct data_bittiming_params which contains all the data bittiming parameters, including the TDC and the callback functions.

2025-03-14can: ucan: fix out of bound read in strscpy() sourceVincent Mailhol
Commit 7fdaf8966aae ("can: ucan: use strscpy() to instead of strncpy()") unintentionally introduced a one byte out of bound read on strscpy()'s source argument (which is kind of ironic knowing that strscpy() is meant to be a more secure alternative :)). Let's consider below buffers: dest[len + 1]; /* will be NUL terminated */ src[len]; /* may not be NUL terminated */ When doing: strncpy(dest, src, len); dest[len] = '\0'; strncpy() will read up to len bytes from src. On the other hand: strscpy(dest, src, len + 1); will read up to len + 1 bytes from src, that is to say, an out of bound read of one byte will occur on src if it is not NUL terminated. Note that the src[len] byte is never copied, but strscpy() still needs to read it to check whether a truncation occurred or not. This exact pattern happened in ucan. The root cause is that the source is not NUL terminated. Instead of doing a copy in a local buffer, directly NUL terminate it as soon as usb_control_msg() returns. With this, the local firmware_str[] variable can be removed. On top of this do a couple refactors: - ucan_ctl_payload->raw is only used for the firmware string, so rename it to ucan_ctl_payload->fw_str and change its type from u8 to char. - ucan_device_request_in() is only used to retrieve the firmware string, so rename it to ucan_get_fw_str() and refactor it to make it directly handle all the string termination logic.

Charan Pedumuru converts the atmel-can DT bindings to DT schema. The next 2 patches are by Oliver Hartkopp. The first one maps Oliver's former mail addresses to a dedicated CAN mail address. The second one assigns net/sched/em_canid.c additionally to the CAN maintainers. Ariel Otilibili's patch removes dead code from the CAN dev helper. The next 3 patches are by Sean Nyekjaer and add HW standby support to the tcan4x5x driver. A patch by Dario Binacchi fixes the DT bindings for the st,stm32-bxcan driver.

2024-11-26can: gs_usb: add usb endpoint address detection at driver probe stepAlexander Kozhinov
There is an approach made to implement gs_usb firmware/driver based on Zephyr RTOS. It was found that USB stack of Zephyr RTOS overwrites USB EP addresses, if they have different last 4 bytes in absence of other endpoints. For example in case of gs_usb candlelight firmware EP-IN is 0x81 and EP-OUT 0x02. If there are no additional USB endpoints, Zephyr RTOS will overwrite EP-OUT to 0x01. More information can be found in the discussion with Zephyr RTOS USB stack maintainer here: https://github.com/zephyrproject-rtos/zephyr/issues/67812 There are already two different gs_usb FW driver implementations based on Zephyr RTOS: 1. https://github.com/CANnectivity/cannectivity (by: https://github.com/henrikbrixandersen) 2. https://github.com/zephyrproject-rtos/zephyr/compare/main...KozhinovAlexander:zephyr:gs_usb (by: https://github.com/KozhinovAlexander) At the moment both Zephyr RTOS implementations use dummy USB endpoint, to overcome described USB stack behavior from Zephyr itself. Since Zephyr RTOS is intended to be used on microcontrollers with very constrained amount of resources (ROM, RAM) and additional endpoint requires memory, it is more convenient to update the gs_usb driver in the Linux kernel. To fix this problem, update the gs_usb driver from using hard coded endpoint numbers to evaluate the endpoint descriptors and use the endpoints provided there.

2024-08-30can: kvaser_usb: Simplify with dev_err_probe()Yan Zhen
dev_err_probe() is used to log an error message during the probe process of a device. It can simplify the error path and unify a message template. Using this helper is totally fine even if err is known to never be -EPROBE_DEFER. The benefit compared to a normal dev_err() is the standardized format of the error code, it being emitted symbolically and the fact that the error code is returned which allows more compact error paths.

Add hardware timestamp support for all usbcan based devices (M16C). The usbcan firmware is slightly different compared to the other Kvaser USB interfaces: - The timestamp is provided by a 32-bit counter, with 10us resolution. Hence, the hardware timestamp will wrap after less than 12 hours. - Each Rx CAN or Tx ACK command only contains the 16-bits LSB of the timestamp counter. - The 16-bits MSB are sent in an asynchronous event (command), if any change occurred in the MSB since the last event.

This will allow us to simplify our min/max macros enormously, since they can now unconditionally use temporary variables to avoid using the argument values multiple times.
