Data stall seen during peak DL throughput test & packets are dropped by mux layer due to invalid header type in datagram. During initlization Mux aggregration protocol is set to default UL/DL size and TD count of Mux lite protocol. This configuration mismatch between device and driver is resulting in data stall/packet drops. Override the UL/DL size and TD count for Mux aggregation protocol.

With INTEL_IOMMU disable config or by forcing intel_iommu=off from grub some of the features of IOSM driver like browsing, flashing & coredump collection is not working. When driver calls DMA API - dma_map_single() for tx transfers. It is resulting in dma mapping error.

Previously, the default number of transmit queues was 16. Due to resource concerns, set to 8 queues instead. Still allow the user to set more queues (max 16) if they like. Since the driver is virtualized away from the physical NIC, the purpose of multiple queues is purely to allow for parallel calls to the hypervisor. Therefore, there is no noticeable effect on performance by reducing queue count to 8. Fixes: d926793c ("ibmveth: Implement multi queue on xmit") Reported-by:

Merge tag 'linux-can-fixes-for-6.1-20221107' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can Marc Kleine-Budde says: ==================== can 2022-11-07 The first patch is by Chen Zhongjin and adds a missing dev_remove_pack() to the AF_CAN protocol. Zhengchao Shao's patch fixes a potential NULL pointer deref in AF_CAN's can_rx_register(). The next patch is by Oliver Hartkopp and targets the CAN ISO-TP protocol, and fixes the state handling for echo TX processing. Oliver Hartkopp's patch for the j1939 protocol adds a missing initialization of the CAN headers inside outgoing skbs. Another patch by Oliver Hartkopp fixes an out of bounds read in the check for invalid CAN frames in the xmit callback of virtual CAN devices. This touches all non virtual device drivers as we decided to rename the function requiring that netdev_priv points to a struct can_priv. (Note: This patch will create a merge conflict with net-next where the pch_can driver has removed.) The last patch is by Geert Uytterhoeven and adds the missing ECC error checks for the channels 2-7 in the rcar_canfd driver. * tag 'linux-can-fixes-for-6.1-20221107' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: can: rcar_canfd: Add missing ECC error checks for channels 2-7 can: dev: fix skb drop check can: j1939: j1939_send_one(): fix missing CAN header initialization can: isotp: fix tx state handling for echo tx processing can: af_can: fix NULL pointer dereference in can_rx_register() can: af_can: can_exit(): add missing dev_remove_pack() of canxl_packet ==================== Link: https://lore.kernel.org/r/20221107133217.59861-1-mkl@pengutronix.deSigned-off-by:

There are two problems with meson8b_devm_clk_prepare_enable(), introduced in commit a54dc4a4 ("net: stmmac: dwmac-meson8b: Make the clock enabling code re-usable"): - It doesn't pass the clk argument, but instead always the rgmii_tx_clk of the device. - It silently ignores the return value of devm_add_action_or_reset(). The former didn't become an actual bug until another user showed up in the next commit 9308c476 ("net: stmmac: dwmac-meson8b: add support for the RX delay configuration"). The latter means the callers could end up with the clock not actually prepared/enabled. Fixes: a54dc4a4 ("net: stmmac: dwmac-meson8b: Make the clock enabling code re-usable") Signed-off-by:

When introducing support for R-Car V3U, which has 8 instead of 2 channels, the ECC error bitmask was extended to take into account the extra channels, but rcar_canfd_global_error() was not updated to act upon the extra bits. Replace the RCANFD_GERFL_EEF[01] macros by a new macro that takes the channel number, fixing R-Car V3U while simplifying the code.

In commit a6d190f8 ("can: skb: drop tx skb if in listen only mode") the priv->ctrlmode element is read even on virtual CAN interfaces that do not create the struct can_priv at startup. This out-of-bounds read may lead to CAN frame drops for virtual CAN interfaces like vcan and vxcan. This patch mainly reverts the original commit and adds a new helper for CAN interface drivers that provide the required information in struct can_priv.

In commit 4b7fe92c ("can: isotp: add local echo tx processing for consecutive frames") the data flow for consecutive frames (CF) has been reworked to improve the reliability of long data transfers. This rework did not touch the transmission and the tx state changes of single frame (SF) transfers which likely led to the WARN in the isotp_tx_timer_handler() catching a wrong tx state. This patch makes use of the improved frame processing for SF frames and sets the ISOTP_SENDING state in isotp_sendmsg() within the cmpxchg() condition handling. A review of the state machine and the timer handling additionally revealed a missing echo timeout handling in the case of the burst mode in isotp_rcv_echo() and removes a potential timer configuration uncertainty in isotp_rcv_fc() when the receiver requests consecutive frames.

It causes NULL pointer dereference when testing as following: (a) use syscall(__NR_socket, 0x10ul, 3ul, 0) to create netlink socket. (b) use syscall(__NR_sendmsg, ...) to create bond link device and vxcan link device, and bind vxcan device to bond device (can also use ifenslave command to bind vxcan device to bond device). (c) use syscall(__NR_socket, 0x1dul, 3ul, 1) to create CAN socket. (d) use syscall(__NR_bind, ...) to bind the bond device to CAN socket. The bond device invokes the can-raw protocol registration interface to receive CAN packets. However, ml_priv is not allocated to the dev, dev_rcv_lists is assigned to NULL in can_rx_register(). In this case, it will occur the NULL pointer dereference issue. The following is the stack information: BUG: kernel NULL pointer dereference, address: 0000000000000008 PGD 122a4067 P4D 122a4067 PUD 1223c067 PMD 0 Oops: 0000 [#1] PREEMPT SMP RIP: 0010:can_rx_register+0x12d/0x1e0 Call Trace: <TASK> raw_enable_filters+0x8d/0x120 raw_enable_allfilters+0x3b/0x130 raw_bind+0x118/0x4f0 __sys_bind+0x163/0x1a0 __x64_sys_bind+0x1e/0x30 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x63/0xcd </TASK> Fixes: 4e096a18 ("net: introduce CAN specific pointer in the struct net_device") Signed-off-by:
