2023-08-22vrf: Remove unnecessary RCU-bh critical sectionIdo Schimmel
dev_queue_xmit_nit() already uses rcu_read_lock() / rcu_read_unlock() and nothing suggests that softIRQs should be disabled around it. Therefore, remove the rcu_read_lock_bh() / rcu_read_unlock_bh() surrounding it. Tested using [1] with lockdep enabled.

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.

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.

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 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.
