2025-03-07net: bcmgenet: consolidate dma initializationDoug Berger
The functions bcmgenet_dma_disable and bcmgenet_enable_dma are only used as part of dma initialization. Their functionality is moved inside bcmgenet_init_dma and the functions are removed. Since the dma is always disabled inside of bcmgenet_init_dma, the initialization functions bcmgenet_init_rx_queues and bcmgenet_init_tx_queues no longer need to attempt to manage its state.

2025-03-07net: bcmgenet: move DESC_INDEX flow to ring 0Doug Berger
The default transmit and receive packet handling is moved from the DESC_INDEX (i.e. 16) descriptor rings to the Ring 0 queues. This saves a fair amount of special case code by unifying the handling. A default dummy filter is enabled in the Hardware Filter Block to route default receive packets to Ring 0.

2025-03-07Bluetooth: btusb: Configure altsetting for HCI_USER_CHANNELHsin-chen Chuang
Automatically configure the altsetting for HCI_USER_CHANNEL when a SCO is connected. The motivation is to enable the HCI_USER_CHANNEL user to send out SCO data through USB Bluetooth chips, which is mainly used for bidirectional audio transfer (voice call). This was not capable because: - Per Bluetooth Core Spec v5, Vol 4, Part B, 2.1, the corresponding alternate setting should be set based on the air mode in order to transfer SCO data, but - The Linux Bluetooth HCI_USER_CHANNEL exposes the Bluetooth Host Controller Interface to the user space, which is something above the USB layer. The user space is not able to configure the USB alt while keeping the channel open. This patch intercepts the HCI_EV_SYNC_CONN_COMPLETE packets in btusb, extracts the air mode, and configures the alt setting in btusb. This patch is tested on ChromeOS devices. The USB Bluetooth models (CVSD, TRANS alt3 and alt6) could work without a customized kernel.

2025-03-07virt: sev-guest: Move SNP Guest Request data pages handling under snp_cmd_mutexAlexey Kardashevskiy
Compared to the SNP Guest Request, the "Extended" version adds data pages for receiving certificates. If not enough pages provided, the HV can report to the VM how much is needed so the VM can reallocate and repeat. Commit ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex") moved handling of the allocated/desired pages number out of scope of said mutex and create a possibility for a race (multiple instances trying to trigger Extended request in a VM) as there is just one instance of snp_msg_desc per /dev/sev-guest and no locking other than snp_cmd_mutex. Fix the issue by moving the data blob/size and the GHCB input struct (snp_req_data) into snp_guest_req which is allocated on stack now and accessed by the GHCB caller under that mutex. Stop allocating SEV_FW_BLOB_MAX_SIZE in snp_msg_alloc() as only one of four callers needs it. Free the received blob in get_ext_report() right after it is copied to the userspace. Possible future users of snp_send_guest_request() are likely to have different ideas about the buffer size anyways.

2025-03-07wifi: iwlwifi: trans: cancel restart work on op mode leaveMiri Korenblit
If the restart work happens to run after the opmode left (i.e. called iwl_trans_op_mode_leave), then the opmode memory (including its mutex) is likely to be freed already, and trans->opmode is NULL. Although the hw is stopped in that stage, which means that this restart got aborted (i.e. STATUS_RESET_PENDING will be cleared), it still can access trans->opmode (NULL pointer dereference) or the opmodes memory (which is freed). Fix this by canceling the restart wk in iwl_trans_op_mode_leave. Also make sure that the restart wk is really aborted.

2025-03-07wifi: iwlwifi: mvm: fix PNVM timeout for non-MSI-X platformsEmmanuel Grumbach
When MSI-X is not enabled, we mask all the interrupts in the interrupt handler and re-enable them when the interrupt thread runs. If STATUS_INT_ENABLED is not set, we won't re-enable in the thread. In order to get the ALIVE interrupt, we allow the ALIVE interrupt itself, and RX as well in order to receive the ALIVE notification (which is received as an RX from the firmware. The problem is that STATUS_INT_ENABLED is clear until the op_mode calls trans_fw_alive which means that until trans_fw_alive is called, any notification from the firmware will not be received. This became a problem when we inserted the pnvm_load exactly between the ALIVE and trans_fw_alive. Fix that by calling trans_fw_alive before loading the PNVM. This will allow to get the notification from the firmware about PNVM load being complete and continue the flow normally. This didn't happen on MSI-X because we don't disable the interrupts in the ISR when MSI-X is available. The error in the log looks like this: iwlwifi 0000:00:03.0: Timeout waiting for PNVM load! iwlwifi 0000:00:03.0: Failed to start RT ucode: -110 iwlwifi 0000:00:03.0: WRT: Collecting data: ini trigger 13 fired (delay=0ms).

2025-03-06fs/pipe: add simpler helpers for common casesLinus Torvalds
The fix to atomically read the pipe head and tail state when not holding the pipe mutex has caused a number of headaches due to the size change of the involved types. It turns out that we don't have _that_ many places that access these fields directly and were affected, but we have more than we strictly should have, because our low-level helper functions have been designed to have intimate knowledge of how the pipes work. And as a result, that random noise of direct 'pipe->head' and 'pipe->tail' accesses makes it harder to pinpoint any actual potential problem spots remaining. For example, we didn't have a "is the pipe full" helper function, but instead had a "given these pipe buffer indexes and this pipe size, is the pipe full". That's because some low-level pipe code does actually want that much more complicated interface. But most other places literally just want a "is the pipe full" helper, and not having it meant that those places ended up being unnecessarily much too aware of this all. It would have been much better if only the very core pipe code that cared had been the one aware of this all. So let's fix it - better late than never. This just introduces the trivial wrappers for "is this pipe full or empty" and to get how many pipe buffers are used, so that instead of writing if (pipe_full(pipe->head, pipe->tail, pipe->max_usage)) the places that literally just want to know if a pipe is full can just say if (pipe_is_full(pipe)) instead. The existing trivial cases were converted with a 'sed' script. This cuts down on the places that access pipe->head and pipe->tail directly outside of the pipe code (and core splice code) quite a lot. The splice code in particular still revels in doing the direct low-level accesses, and the fuse fuse_dev_splice_write() code also seems a bit unnecessarily eager to go very low-level, but it's at least a bit better than it used to be.

2025-03-06net/mlx5e: Properly match IPsec subnet addressesLeon Romanovsky
Existing match criteria didn't allow to match whole subnet and only by specific addresses only. This caused to tunnel mode do not forward such traffic through relevant SA. In tunnel mode, policies look like this: src 192.169.0.0/16 dst 192.169.0.0/16 dir out priority 383615 ptype main tmpl src 192.169.101.2 dst 192.169.101.1 proto esp spi 0xc5141c18 reqid 1 mode tunnel crypto offload parameters: dev eth2 mode packet In this case, the XFRM core code handled all subnet calculations and forwarded network address to the drivers e.g. 192.169.0.0. For mlx5 devices, there is a need to set relevant prefix e.g. 0xFFFF00 to perform flow steering match operation.

2025-03-06net/mlx5e: Enable lanes configuration when auto-negotiation is offShahar Shitrit
Currently, when auto-negotiation is disabled, the driver retrieves the speed and converts it into all link modes that correspond to that speed. With this patch, we add the ability to set the number of lanes, so that the combination of speed and lanes corresponds to exactly one specific link mode for the extended bit map. For the legacy bit map the driver sets all link modes correspond to speed and lanes. This change provides users with the option to set a specific link mode, rather than enabling all link modes associated with a given speed when auto-negotiation is off.

2025-03-06net/mlx5: Refactor link speed handling with mlx5_link_info structShahar Shitrit
Introduce struct mlx5_link_info with a speed field and change the types of mlx5e_link_speed and mlx5e_ext_link_speed from arrays of u32 to arrays of struct mlx5_link_info. These arrays are renamed to mlx5e_link_info and mlx5e_ext_link_info, respectively. This change prepares for a future patch that will introduce a lanes field in struct mlx5_link_info and add lanes mapping alongside the speed for each link mode in the two arrays. Additionally, rename function mlx5_port_speed2linkmodes() to mlx5_port_info2linkmodes() and function mlx5_port_ptys2speed() to mlx5_port_ptys2info() and update the speed parameter/return type to struct mlx5_link_info, in preparation for the upcoming patch where these functions will also utilize the lanes field.

The port header is a general file under include, yet it contains declarations for functions that are either not exported or exported but not used outside the mlx5_core driver. To enhance code organization, we move these declarations to mlx5_core.h, where they are more appropriately scoped.

2025-03-06net: ti: icss-iep: Add phase offset configuration for perout signalMeghana Malladi
icss_iep_perout_enable_hw() is a common function for generating both pps and perout signals. When enabling pps, the application needs to only pass enable/disable argument, whereas for perout it supports different flags to configure the signal. In case the app passes a valid phase offset value, the signal should start toggling after that phase offset, else start immediately or as soon as possible. ICSS_IEP_SYNC_START_REG register take number of clock cycles to wait before starting the signal after activation time. Set appropriate value to this register to support phase offset.

icss_iep_perout_enable_hw() is a common function for generating both pps and perout signals. When enabling pps, the application needs to only pass enable/disable argument, whereas for perout it supports different flags to configure the signal. But icss_iep_perout_enable_hw() function is missing to hook the configuration params passed by the app, causing perout to behave same a pps (except being able to configure the period). As duty cycle is also one feature which can configured for perout, incorporate this in the function to get the expected signal.
