2022-09-22bnxt_en: replace reset with config timestampsVadim Fedorenko
Any change to the hardware timestamps configuration triggers nic restart, which breaks transmition and reception of network packets for a while. But there is no need to fully restart the device because while configuring hardware timestamps. The code for changing configuration runs after all of the initialisation, when the NIC is actually up and running. This patch changes the code that ioctl will only update configuration registers and will not trigger carrier status change, but in case of timestamps for all rx packetes it fallbacks to close()/open() sequnce because of synchronization issues in the hardware. Tested on BCM57504.

2022-09-22bnxt: prevent skb UAF after handing over to PTP workerJakub Kicinski
When reading the timestamp is required bnxt_tx_int() hands over the ownership of the completed skb to the PTP worker. The skb should not be used afterwards, as the worker may run before the rest of our code and free the skb, leading to a use-after-free. Since dev_kfree_skb_any() accepts NULL make the loss of ownership more obvious and set skb to NULL.

2022-09-22net: sunhme: Fix packet reception for len < RX_COPY_THRESHOLDSean Anderson
There is a separate receive path for small packets (under 256 bytes). Instead of allocating a new dma-capable skb to be used for the next packet, this path allocates a skb and copies the data into it (reusing the existing sbk for the next packet). There are two bytes of junk data at the beginning of every packet. I believe these are inserted in order to allow aligned DMA and IP headers. We skip over them using skb_reserve. Before copying over the data, we must use a barrier to ensure we see the whole packet. The current code only synchronizes len bytes, starting from the beginning of the packet, including the junk bytes. However, this leaves off the final two bytes in the packet. Synchronize the whole packet. To reproduce this problem, ping a HME with a payload size between 17 and 214 $ ping -s 17 <hme_address> which will complain rather loudly about the data mismatch. Small packets (below 60 bytes on the wire) do not have this issue. I suspect this is related to the padding added to increase the minimum packet size.

Fix a NULL dereference of the struct bonding.rr_tx_counter member because if a bond is initially created with an initial mode != zero (Round Robin) the memory required for the counter is never created and when the mode is changed there is never any attempt to verify the memory is allocated upon switching modes.

2022-09-22wifi: ath11k: fix number of VHT beamformee spatial streamsJesus Fernandez Manzano
The number of spatial streams used when acting as a beamformee in VHT mode are reported by the firmware as 7 (8 sts - 1) both in IPQ6018 and IPQ8074 which respectively have 2 and 4 sts each. So the firmware should report 1 (2 - 1) and 3 (4 - 1). Fix this by checking that the number of VHT beamformee sts reported by the firmware is not greater than the number of receiving antennas - 1. The fix is based on the same approach used in this same function for sanitizing the number of sounding dimensions reported by the firmware. Without this change, acting as a beamformee in VHT mode is not working properly.

2022-09-22wifi: ath11k: add get_txpower mac opsAditya Kumar Singh
Driver does not support get_txpower mac ops because of which cfg80211 returns vif->bss_conf.txpower to user space. bss_conf.txpower gets its value from ieee80211_channel->max_reg_power. However, the final txpower is dependent on few other parameters apart from max regulatory supported power. It is the firmware which knows about all these parameters and considers the minimum for each packet transmission. All ath11k firmware reports the final tx power in firmware pdev stats which falls under fw_stats. Add get_txpower mac ops to get the tx power from firmware leveraging fw_stats and return it accordingly.

Currently, firmware stats, comprising pdev, vdev and beacon stats are part of debugfs. In firmware pdev stats, firmware reports the final Tx power used to transmit each packet.

When running suspend test, kernel crash happened in ath10k, and it is fixed by commit b72a4aff947b ("ath10k: skip ath10k_halt during suspend for driver state RESTARTING"). Currently the crash is fixed, but as a common code style, it is better to set the pointer to NULL after memory is free.

Currently commit 1f682dc9fb37 ("ath11k: reduce the wait time of 11d scan and hw scan while add interface") introduced a wait_for_completion_timeout operation for ar->scan.completed, another one is existed in ath11k_scan_stop(), then ath11k has two places to wait for the ar->scan.completed and they run in different thread, thus it is possible to happend that the two thread both enter wait status. To handle this scenario, ath11k should change the complete() to complete_all() for the ar->scan.completed. This also work well when it is only one thread wait for ar->scan.completed.

[ 135.389205] usb 1-1: == mwifiex dump information to /sys/class/devcoredump end This patch uses delayed work to replace timer and moves the operations that may sleep into a delayed work in order to mitigate bugs, it was tested on Marvell 88W8801 chip whose port is usb and the firmware is usb8801_uapsta.bin. The following is the result after using delayed work to replace timer.

2022-09-21ethernet: tundra: Drop forward declaration of static functionsUwe Kleine-König
Usually it's not necessary to declare static functions if the symbols are in the right order. Moving the definition of tsi_eth_driver down in the compilation unit allows to drop two such declarations.
