2020-08-26bnxt_en: Fix possible crash in bnxt_fw_reset_task().Michael Chan1-2/+8
bnxt_fw_reset_task() is run from a delayed workqueue. The current code is not cancelling the workqueue in the driver's .remove() method and it can potentially crash if the device is removed with the workqueue still pending. The fix is to clear the BNXT_STATE_IN_FW_RESET flag and then cancel the delayed workqueue in bnxt_remove_one(). bnxt_queue_fw_reset_work() also needs to check that this flag is set before scheduling. This will guarantee that no rescheduling will be done after it is cancelled. Fixes: 230d1f0de754 ("bnxt_en: Handle firmware reset.")

2020-08-26bnxt_en: Fix ethtool -S statitics with XDP or TCs enabled.Michael Chan1-9/+2
We are returning the wrong count for ETH_SS_STATS in get_sset_count() when XDP or TCs are enabled. In a recent commit, we got rid of irrelevant counters when the ring is RX only or TX only, but we did not make the proper adjustments for the count. As a result, when we have XDP or TCs enabled, we are returning an excess count because some of the rings are TX only. This causes ethtool -S to display extra counters with no counter names. Fix bnxt_get_num_ring_stats() by not assuming that all rings will always have RX and TX counters in combined mode.

2020-08-25ibmvnic fix NULL tx_pools and rx_tools issue at do_resetMingming Cao1-1/+14
At the time of do_rest, ibmvnic tries to re-initalize the tx_pools and rx_pools to avoid re-allocating the long term buffer. However there is a window inside do_reset that the tx_pools and rx_pools were freed before re-initialized making it possible to deference null pointers. This patch fix this issue by always check the tx_pool and rx_pool are not NULL after ibmvnic_login. If so, re-allocating the pools. This will avoid getting into calling reset_tx/rx_pools with NULL adapter tx_pools/rx_pools pointer. Also add null pointer check in reset_tx_pools and reset_rx_pools to safe handle NULL pointer case.

2020-08-24octeontx2-af: Add support for Marvell PTP coprocessorAleksey Makarov6-4/+348
Precision Timestamping block found on Octeontx2 platform is an independent coprocessor and has internal PTP hardware clock. Once configured PTP runs independently and when a packet arrives CGX hardware block gets the current timestamp from PTP block and forwards the packet to NIX by prepending timestamp to the packet. This patch adds the pci driver for PTP block. The driver gets registered by AF driver and does initial configuration and exposes a mailbox function to read and adjust PTP hardware clock. The mailbox function is called by AF consumers like netdev drivers or userspace drivers. Since PTP being a single block in platform this driver helps in accessing PTP block by any AF consumer.

2020-08-24typhoon: switch from 'pci_' to 'dma_' APIChristophe JAILLET1-31/+30
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'typhoon_init_one()' GFP_KERNEL can be used because it is a probe function and no lock is acquired. When memory is allocated in 'typhoon_download_firmware()', GFP_ATOMIC must be used because it can be called from a .ndo_tx_timeout function. So this function can be called with the 'netif_tx_lock' acquired.

2020-08-24ravb: Fixed to be able to unload modulesYuusuke Ashizuka1-55/+55
When this driver is built as a module, I cannot rmmod it after insmoding it. This is because that this driver calls ravb_mdio_init() at the time of probe, and module->refcnt is incremented by alloc_mdio_bitbang() called after that. Therefore, even if ifup is not performed, the driver is in use and rmmod cannot be performed. $ lsmod Module Size Used by ravb 40960 1 $ rmmod ravb rmmod: ERROR: Module ravb is in use Call ravb_mdio_init() at open and free_mdio_bitbang() at close, thereby rmmod is possible in the ifdown state.

Commit 8dcf2ad39fdb2 ("net: atlantic: add hwmon getter for MAC temperature") implemented a read callback with an udelay(10000U). This fails to compile on ARM because the delay is >1ms. I doubt that it is needed to spin for 10ms even if possible on x86. >From looking at the code, the context appears to be preemptible so using usleep() should work and avoid busy spinning. Use readx_poll_timeout() in the poll loop.
