2021-08-30bnxt_en: remove DMA mapping for KONG responseEdwin Peer2-51/+7
The additional response buffer serves no useful purpose. There can be only one firmware command in flight due to the hwrm_cmd_lock mutex, which is taken for the entire duration of any command completion, KONG or otherwise. It is thus safe to share a single DMA buffer. Removing the code associated with the additional mapping will simplify matters in the next patch, which allocates response buffers from DMA pools on a per request basis.

2021-08-29mwifiex: pcie: add reset_d3cold quirk for Surface gen4+ devicesTsuchiya Yuto3-0/+133
To reset mwifiex on Surface gen4+ (Pro 4 or later gen) devices, it seems that putting the wifi device into D3cold is required according to errata.inf file on Windows installation (Windows/INF/errata.inf). This patch adds a function that performs power-cycle (put into D3cold then D0) and call the function at the end of reset_prepare(). Note: Need to also reset the parent device (bridge) of wifi on SB1; it might be because the bridge of wifi always reports it's in D3hot. When I tried to reset only the wifi device (not touching parent), it gave the following error and the reset failed: acpi device:4b: Cannot transition to power state D0 for parent in D3hot mwifiex_pcie 0000:03:00.0: can't change power state from D3cold to D0 (config space inaccessible) Signed-off-by: Tsuchiya Yuto <kitakar@gmail.com> Signed-off-by: Jonas Dreßler <verdre@v0yd.nl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20210820142050.35741-3-verdre@v0yd.nl

2021-08-29brcmfmac: pcie: fix oops on failure to resume and reprobeAhmad Fatoum1-1/+1
When resuming from suspend, brcmf_pcie_pm_leave_D3 will first attempt a hot resume and then fall back to removing the PCI device and then reprobing. If this probe fails, the kernel will oops, because brcmf_err, which is called to report the failure will dereference the stale bus pointer. Open code and use the default bus-less brcmf_err to avoid this.

kmemleak reported that dev_name() of internally-handled cores were leaked on driver unbinding. Let's use device_initialize() to take refcounts for them and put_device() to properly free the related stuff. While looking at it, there's another potential issue for those which should be *registered* into driver core. If device_register() failed, we put device once and freed bcma_device structures. In bcma_unregister_cores(), they're treated as unregistered and we hit both UAF and double-free. That smells not good and has also been fixed now.

The OOB, triggered by the condition length > cptr could cause memory error with a read on negative index. There are some sanity check around length, but it is not compared with cptr (the remaining bytes). Here, the corrupted/bad EEPROM can cause panic.

The WLAN NV firmware blob differs between platforms, and possibly devices, so add support in the wcn36xx driver for reading the path of this file from DT in order to allow these files to live in a generic file system (or linux-firmware). For some reason the parent (wcnss_ctrl) also needs to upload this blob, so rather than specifying the same information in both nodes wcn36xx reads the string from the parent's of_node.

2021-08-29wcn36xx: Ensure finish scan is not requested before start scanJoseph Gates2-1/+5
If the operating channel is the first in the scan list, it was seen that a finish scan request would be sent before a start scan request was sent, causing the firmware to fail all future scans. Track the current channel being scanned to avoid requesting the scan finish before it starts.

2021-08-28ionic: fire watchdog again after fw_downShannon Nelson1-2/+9
In some cases of fw_down it was called because there was a fw_generation change, and the firmware is already back up. In order to keep the down time to a minimum, don't wait for the next watchdog polling cycle, fire another watchdog off as soon as we can - an out-of-cycle check won't hurt, and may well speed up the recovery.

2021-08-28bnxt: count packets discarded because of netpollJakub Kicinski3-1/+13
bnxt may discard packets if Rx completions are consumed in an attempt to let netpoll make progress. It should be extremely rare in practice but nonetheless such events should be counted. Since completion ring memory is allocated dynamically use a similar scheme to what is done for HW stats to save them. Report the stats in rx_dropped and per-netdev ethtool counter. Chances that users care which ring dropped are very low. v3: only save the stat to rx_dropped on reset, rx_total_netpoll_discards will now only show drops since last reset, similar to other "total_discard" counters.

2021-08-27igc: Add support for CBS offloadingAravindhan Gunasekaran5-1/+195
Implement support for Credit-based shaper(CBS) Qdisc hardware offload mode in the driver. There are two sets of IEEE802.1Qav (CBS) HW logic in i225 controller and this patch supports enabling them in the top two priority TX queues. Driver implemented as recommended by Foxville External Architecture Specification v0.993. Idleslope and Hi-credit are the CBS tunable parameters for i225 NIC, programmed in TQAVCC and TQAVHC registers respectively. In-order for IEEE802.1Qav (CBS) algorithm to work as intended and provide BW reservation CBS should be enabled in highest priority queue first. If we enable CBS on any of low priority queues, the traffic in high priority queue does not allow low priority queue to be selected for transmission and bandwidth reservation is not guaranteed.
