2023-08-22wifi: ath9k: Remove unused declarationsYue Haibing
Commit b57ba3b2f7b0 ("ath9k: move ath9k_reload_chainmask_settings to common") removed the implementation ath9k_reload_chainmask_settings() but not the declaration. Also commit 978f78bf7137 ("ath9k_hw: Move bt_stomp to hw from common.") left behind ath9k_cmn_btcoex_bt_stomp() declaration.

2023-08-22wifi: ath9k: protect WMI command response buffer replacement with a lockFedor Pchelkin
If ath9k_wmi_cmd() has exited with a timeout, it is possible that during next ath9k_wmi_cmd() call the wmi_rsp callback for previous wmi command writes to new wmi->cmd_rsp_buf and makes a completion. This results in an invalid ath9k_wmi_cmd() return value. Move the replacement of WMI command response buffer and length under wmi_lock. Note that last_seq_id value is updated there, too. Thus, the buffer cannot be written to by a belated wmi_rsp callback because that path is properly rejected by the last_seq_id check.

2023-08-22wifi: ath9k: fix races between ath9k_wmi_cmd and ath9k_wmi_ctrl_rxFedor Pchelkin
Currently, the synchronization between ath9k_wmi_cmd() and ath9k_wmi_ctrl_rx() is exposed to a race condition which, although being rather unlikely, can lead to invalid behaviour of ath9k_wmi_cmd(). Consider the following scenario: CPU0 CPU1 ath9k_wmi_cmd(...) mutex_lock(&wmi->op_mutex) ath9k_wmi_cmd_issue(...) wait_for_completion_timeout(...) --- timeout --- /* the callback is being processed * before last_seq_id became zero */ ath9k_wmi_ctrl_rx(...) spin_lock_irqsave(...) /* wmi->last_seq_id check here * doesn't detect timeout yet */ spin_unlock_irqrestore(...) /* last_seq_id is zeroed to * indicate there was a timeout */ wmi->last_seq_id = 0 mutex_unlock(&wmi->op_mutex) return -ETIMEDOUT ath9k_wmi_cmd(...) mutex_lock(&wmi->op_mutex) /* the buffer is replaced with * another one */ wmi->cmd_rsp_buf = rsp_buf wmi->cmd_rsp_len = rsp_len ath9k_wmi_cmd_issue(...) spin_lock_irqsave(...) spin_unlock_irqrestore(...) wait_for_completion_timeout(...) /* the continuation of the * callback left after the first * ath9k_wmi_cmd call */ ath9k_wmi_rsp_callback(...) /* copying data designated * to already timeouted * WMI command into an * inappropriate wmi_cmd_buf */ memcpy(...) complete(&wmi->cmd_wait) /* awakened by the bogus callback * => invalid return result */ mutex_unlock(&wmi->op_mutex) return 0 To fix this, update last_seq_id on timeout path inside ath9k_wmi_cmd() under the wmi_lock. Move ath9k_wmi_rsp_callback() under wmi_lock inside ath9k_wmi_ctrl_rx() so that the wmi->cmd_wait can be completed only for initially designated wmi_cmd call, otherwise the path would be rejected with last_seq_id check.

When a Linux VM with an assigned PCI device runs on Hyper-V, if the PCI device driver is not loaded yet (i.e. MSI-X/MSI is not enabled on the device yet), doing a VM hibernation triggers a panic in hv_pci_restore_msi_msg() -> msi_lock_descs(&pdev->dev), because pdev->dev.msi.data is still NULL.

2023-08-22btrfs: zoned: skip splitting and logical rewriting on pre-alloc writeNaohiro Aota
When doing a relocation, there is a chance that at the time of btrfs_reloc_clone_csums(), there is no checksum for the corresponding region. In this case, btrfs_finish_ordered_zoned()'s sum points to an invalid item and so ordered_extent's logical is set to some invalid value. Then, btrfs_lookup_block_group() in btrfs_zone_finish_endio() failed to find a block group and will hit an assert or a null pointer dereference as following. This can be reprodcued by running btrfs/028 several times (e.g, 4 to 16 times) with a null_blk setup. The device's zone size and capacity is set to 32 MB and the storage size is set to 5 GB on my setup.

2023-08-22ASoC: SOF: ipc4-topology: Add module parameter to ignore the CPC valuePeter Ujfalusi
Add a new module parameter ipc4_ignore_cpc which can be used to force the kernel to ignore the queried CPC value for all firmware modules and use 0 instead. The CPC lookup is still done to report missing configurations and the debug print is going to be different to be explicit that the CPC is ignored and what was the value we would have used. The CPC value is sent to the firmware with the MOD_INIT_INSTANCE message and it is used by the firmware as a parameter for clock scaling. The flag is intended to be used only when there is a need to validate the firmware behavior regarding to clock scaling since the 0 CPC value will force the DSP to run in full speed, disabling the scaling and provides additional counter point to rule out clock management related issues.

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: This patch chain adds support for the Cirrus Logic cs42l43 PC focused SoundWire CODEC. The chain is currently based of Lee's for-mfd-next branch. This series is mostly just a resend keeping pace with the kernel under it, except for a minor fixup in the ASoC stuff.

2023-08-22super: use higher-level helper for {freeze,thaw}Christian Brauner
It's not necessary to use low-level locking helpers here. Use the higher-level locking helpers and log if the superblock is dying. Since the caller is assumed to already hold an active reference it isn't possible to observe a dying superblock.

In case the SAP connection is established before the interface is added, the mac address is still not set. Don't send the nic info SAP message in this case since it will result in sending an invalid mac address. The nic info message will be sent with a valid mac address when the interface is added.

2023-08-22wifi: iwlwifi: pcie: avoid a warning in case prepare card failedAvraham Stern
In case CSME holds the NIC and SAP connection is already established, iwl_pcie_prepare_card_hw() during iwl_pci_probe() will fail (which is fine since CSME will release the nic later when asked with a SAP message). In this case tring to grab nic access to read the crf ids will fail with a warning. Avoid the warning by only trying to read the crf ids in case prepare card succeeded.

2023-08-22wifi: iwlwifi: remove memory check for LMAC error addressMukesh Sisodiya
LMAC error table address was checked against UMAC error table minimum address defined. Because of that, the LMAC error table was not read, since both addresses belong to different ranges. As addresses are updated from FW alive message and should be correct, this check is not needed. Still keep the check for address 0 to avoid NULL address read.
