Merge tag 'linux-can-next-for-5.15-20210725' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next linux-can-next-for-5.15-20210725 Marc Kleine-Budde says: ==================== pull-request: can-next 2021-07-25 this is a pull request of 46 patches for net-next/master. The first 6 patches target the CAN J1939 protocol. One is from gushengxian, fixing a grammatical error, 5 are by me fixing a checkpatch warning, make use of the fallthrough pseudo-keyword, and use consistent variable naming. The next 3 patches target the rx-offload helper, are by me and improve the performance and fix the local softirq work pending error, when napi_schedule() is called from threaded IRQ context. The next 3 patches are by Vincent Mailhol and me update the CAN bittiming and transmitter delay compensation, the documentation for the struct can_tdc is fixed, clear data_bittiming if FD mode is turned off and a redundant check is removed. Followed by 4 patches targeting the m_can driver. Faiz Abbas's patches add support for CAN PHY via the generic phy subsystem. Yang Yingliang converts the driver to use devm_platform_ioremap_resource_byname(). And a patch by me which removes the unused support for custom bit timing. Andy Shevchenko contributes 2 patches for the mcp251xfd driver to prepare the driver for ACPI support. A patch by me adds support for shared IRQ handlers. Zhen Lei contributes 3 patches to convert the esd_usb2, janz-ican3 and the at91_can driver to make use of the DEVICE_ATTR_RO/RW() macros. The next 8 patches are by Peng Li and provide general cleanups for the at91_can driver. The next 7 patches target the peak driver. Frist 2 cleanup patches by me for the peak_pci driver, followed by Stephane Grosjean' patch to print the name and firmware version of the detected hardware. The peak_usb driver gets a cleanup patch, loopback and one-shot mode and an upgrading of the bus state change handling in Stephane Grosjean's patches. Vincent Mailhol provides 6 cleanup patches for the etas_es58x driver. In the last 3 patches Angelo Dureghello add support for the mcf5441x SoC to the flexcan driver. ==================== Signed-off-by:

The dma_pool_zalloc combines dma_pool_alloc/memset. Therefore, the dma_pool_alloc/memset can be replaced with dma_pool_zalloc which is more compact. Signed-off-by:

Packets are aggregated over the MBIM link and currently the MHI net device will count each aggregated packet rather then the actual packets themselves. If a protocol handler module is specified, use that to count the packets rather than directly in the MHI net device. This is in line with the behaviour of the USB net cdc_mbim driver. Signed-off-by:

syzbot reported an use-after-free crash: BUG: KASAN: use-after-free in tipc_recvmsg+0xf77/0xf90 net/tipc/socket.c:1979 Call Trace: tipc_recvmsg+0xf77/0xf90 net/tipc/socket.c:1979 sock_recvmsg_nosec net/socket.c:943 [inline] sock_recvmsg net/socket.c:961 [inline] sock_recvmsg+0xca/0x110 net/socket.c:957 tipc_conn_rcv_from_sock+0x162/0x2f0 net/tipc/topsrv.c:398 tipc_conn_recv_work+0xeb/0x190 net/tipc/topsrv.c:421 process_one_work+0x98d/0x1630 kernel/workqueue.c:2276 worker_thread+0x658/0x11f0 kernel/workqueue.c:2422 As Hoang pointed out, it was caused by skb_cb->bytes_read still accessed after calling tsk_advance_rx_queue() to free the skb in tipc_recvmsg(). This patch is to fix it by accessing skb_cb->bytes_read earlier than calling tsk_advance_rx_queue().

Add flexcan support for NXP ColdFire mcf5441x family. This flexcan module is quite similar to imx6 flexcan module, but with some exceptions: - 3 separate interrupt sources, MB, BOFF and ERR, - implements 16 mb only, - m68k architecture is not supporting devicetrees, so a platform data check/case has been added, - ColdFire is m68k, so big-endian cpu, with a little-endian flexcan module.

The es581_tx_can_msg() does below cast: | tx_can_msg = (struct es581_4_tx_can_msg *) | &es581_4_urb_cmd->bulk_tx_can_msg.tx_can_msg_buf[msg_len - 1]; The -1 offset is to skip the first member of struct es581_4_tx_can_msg. However, es581_4_urb_cmd already has a raw_msg field which can be used instead without the use of an offset calculation. The function es58x_fd_tx_can_msg() is also modified to mirror es581_tx_can_msg(). Link: https://lore.kernel.org/r/20210628155420.1176217-7-mailhol.vincent@wanadoo.frSigned-off-by:

This patch updates old code by using the can_change_state() function published since by the socket-can module. In particular, this new code better manages the change of bus state by also using the value of the error counters that the driver now systematically asks for when initializing the channel.

The CAN - USB PCAN-USB interface is able to generate one-shot frames as well as loopback frames that it transmits starting from version 4.1 of its firmware. This patch adds support for the one-shot and loopback functionality to the driver, that can be activated if the embedded firmware allows it. If the driver detects that the PCAN-USB device runs an old firmware (< 4.1) it prints a message suggesting to contact <support@peak-system.com> for a possible firmware update.
