2022-12-08net: stmmac: Set MAC's flow control register to reflect current settingsGoh, Wei Sheng2-2/+12
commit cc3d2b5fc0d6f8ad8a52da5ea679e5c2ec2adbd4 upstream. Currently, pause frame register GMAC_RX_FLOW_CTRL_RFE is not updated correctly when 'ethtool -A <IFACE> autoneg off rx off tx off' command is issued. This fix ensures the flow control change is reflected directly in the GMAC_RX_FLOW_CTRL_RFE register.

2022-12-08can: can327: can327_feed_frame_to_netdev(): fix potential skb leak when ↵Ziyang Xuan1-1/+3
netdev is down commit 8fa452cfafed521aaf5a18c71003fe24b1ee6141 upstream. In can327_feed_frame_to_netdev(), it did not free the skb when netdev is down, and all callers of can327_feed_frame_to_netdev() did not free allocated skb too. That would trigger skb leak. Fix it by adding kfree_skb() in can327_feed_frame_to_netdev() when netdev is down. Not tested, just compiled.

[ Upstream commit e87c6a832f889c093c055a30a7b8c6843e6573bf ] If creating bond first and then enabling sriov in switchdev mode, will hit the following syndrome: mlx5_core 0000:08:00.0: mlx5_cmd_out_err:778:(pid 25543): CREATE_LAG(0x840) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x7d49cb), err(-22) The reason is because the offending patch removes eswitch mode none. In vf lag, the checking of eswitch mode none is replaced by checking if sriov is enabled. But when driver enables sriov, it triggers the bond workqueue task first and then setting sriov number in pci_enable_sriov(). So the check fails. Fix it by checking if sriov is enabled using eswitch internal counter that is set before triggering the bond workqueue task.

commit 62f102c0d1563ff6a31082f5d83b886ad2ff7ca0 upstream. DMA allocated buffers are a precious resource. If there is no need for DMA allocations, then it might be worth to use non-dma allocated buffers. After testing the gs_usb driver with and without DMA allocation, there does not seem to be a significant change in latency or CPU utilization either way. Therefore, DMA allocation is not necessary and removed. Internal buffers used within urbs were managed and freed manually. These buffers are no longer needed to be managed by the driver. The URB_FREE_BUFFER flag, allows for the buffers in question to be automatically freed.

In vp_modern_find_vqs(), all queues will be selected and activated, but once queues are enabled there is no way to go back except reset. Fix it by reset virtio device on error handling path. This makes error handling follow the same order as normal device cleanup in virtnet_remove() which does: unregister, destroy failover, then reset.

[ Upstream commit 290b5fe096e7dd0aad730d1af4f7f2d9fea43e11 ] In the blamed commit, a rudimentary reallocation procedure for RX buffer descriptors was implemented, for the situation when their format changes between normal (no PTP) and extended (PTP). enetc_hwtstamp_set() calls enetc_close() and enetc_open() in a sequence, and this sequence loses information which was previously configured in the TX BDR Mode Register, specifically via the enetc_set_bdr_prio() call. The TX ring priority is configured by tc-mqprio and tc-taprio, and affects important things for TSN such as the TX time of packets. The issue manifests itself most visibly by the fact that isochron --txtime reports premature packet transmissions when PTP is first enabled on an enetc interface. Save the TX ring priority in a new field in struct enetc_bdr (occupies a 2 byte hole on arm64) in order to make this survive a ring reconfiguration.
