2023-08-22sfc: allocate a big enough SKB for loopback selftest packetEdward Cree3-3/+3
Cited commits passed a size to alloc_skb that was only big enough for the actual packet contents, but the following skb_put + memcpy writes the whole struct efx_loopback_payload including leading and trailing padding bytes (which are then stripped off with skb_pull/skb_trim). This could cause an skb_over_panic, although in practice we get saved by kmalloc_size_roundup. Pass the entire size we use, instead of the size of the final packet.

2023-08-22leds: trigger: netdev: rename 'hw_control' sysfs entry to 'offloaded'Marek Behún2-14/+14
Commit b655892ffd6d ("leds: trigger: netdev: expose hw_control status via sysfs") exposed to sysfs the flag that tells whether the LED trigger is offloaded to hardware, under the name "hw_control", since that is the name under which this setting is called in the code. Everywhere else in kernel when some work that is normally done in software can be made to be done by hardware instead, we use the word "offloading" to describe this, e.g. "LED blinking is offloaded to hardware". Normally renaming sysfs entries is a no-go because of backwards compatibility. But since this patch was not yet released in a stable kernel, I think it is still possible to rename it, if there is consensus.

2023-08-22wifi: ath9k: protect WMI command response buffer replacement with a lockFedor Pchelkin1-6/+8
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.

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().

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.

2023-08-22wifi: iwlmei: send driver down SAP message only if wiamt is enabledAvraham Stern1-1/+3
When wiamt is disabled the driver up SAP message is not sent, so there is no need to send the driver down message as well.

2023-08-22wifi: iwlmei: send HOST_GOES_DOWN message even if wiamt is disabledAvraham Stern1-23/+19
The HOST_GOES_DOWN message should be sent even if wiamt is disabled. Otherwise wiamt may still use the shared memory (e.g. if enabled later) while it's no longer valid.

2023-08-22wifi: iwlwifi: pcie: avoid a warning in case prepare card failedAvraham Stern1-10/+1
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 Sisodiya1-2/+1
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.

There are occasionally bugs which cause the device to try to use a TFD that it wasn't supposed to, and these are very hard to diagnose. Fill all unused TFDs with a debug command that immediately causes an error to be detected in these cases.
