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. Signed-off-by:

Please let me know if there are any problems. wireless-drivers-next patches for v5.15 Second, and most likely last, set of patches for v5.15. Lots of iwlwifi patches this time, but smaller changes to other drivers as well. Nothing special standing out. Major changes: rtw88 * add quirk to disable pci caps on HP Pavilion 14-ce0xxx brcmfmac * Add WPA3 Personal with FT to supported cipher suites wcn36xx * allow firmware name to be overridden by DT iwlwifi * support scanning hidden 6GHz networks * support for a new hardware family (Bz) * support for new firmware API versions mwifiex * add reset_d3cold quirk for Surface gen4+ devices ==================== Signed-off-by:

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:

This commit adds the ability to apply device-specific quirks to the mwifiex driver. It uses DMI matching similar to the quirks brcmfmac uses with dmi.c.

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. Fixes: 8602e624 ("brcmfmac: pass bus to the __brcmf_err() in pcie.c") Signed-off-by:

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.

Bad header can have large length field which can cause OOB. cptr is the last bytes for read, and the eeprom is parsed from high to low address. 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. I was able to reproduce the crash, but I cannot find the log and the reproducer now. After I applied the patch, the bug is no longer reproducible. Signed-off-by:
