2025-05-21net: introduce CONFIG_NET_CRC32CEric Biggers
Add a hidden kconfig symbol NET_CRC32C that will group together the functions that calculate CRC32C checksums of packets, so that these don't have to be built into NET-enabled kernels that don't need them. Make skb_crc32c_csum_help() (which is called only when IP_SCTP is enabled) conditional on this symbol, and make IP_SCTP select it.

2025-05-21wifi: ath12k: fix regdomain update failure when connection establishesBaochen Qiang
Commit 7ed3e88664e3 ("wifi: ath12k: update regulatory rules when connection established") introduced a call to ath12k_reg_handle_chan_list() upon connection to update the regulatory domain in cfg80211 based on the power type received from the AP. However, this update fails because ah->regd_updated was already set to true during the earlier regulatory update triggered when the interface was added. To resolve this, reset ah->regd_updated before calling ath12k_reg_handle_chan_list() to ensure the update proceeds correctly.

2025-05-21wifi: ath12k: fix regdomain update failure when adding interfaceBaochen Qiang
Commit 4c546023d71a ("wifi: ath12k: update regulatory rules when interface added"), introduced a call to ath12k_reg_handle_chan_list() during interface addition to update the regulatory domain based on the interface type. While this works initially, subsequent updates (e.g., after an interface delete/re-add cycle) fail because ah->regd_updated is never reset. To address this, reset ah->regd_updated before calling ath12k_reg_handle_chan_list() to allow the update to proceed. However, this change exposes another issue: a timeout occurs when waiting for the 11D scan to complete, as seen in the log: ath12k_pci 0000:05:00.0: failed to receive 11d scan complete: timed out This happens because during interface down, ar->state_11d is set to ATH12K_11D_PREPARING, and during interface up, the host waits for ar->completed_11d_scan even though the scan hasn't started yet. Fix this by updating the wait condition to check for ATH12K_11D_RUNNING, which is the only state where a scan complete event is expected.

2025-05-21wifi: ath12k: fix regdomain update failure after 11D scan completesBaochen Qiang
In the current implementation of ath12k_regd_update(), the ah->regd_updated flag is used to ensure that the regulatory domain is updated only once per radio. During MAC registration, this function is called to push the default regulatory domain to cfg80211. At that point, the hardware state is not on and hence ah->regd_updated remains false. However, after commit 4c546023d71a ("wifi: ath12k: update regulatory rules when interface added"), ath12k_reg_handle_chan_list() is invoked when an interface is added, which in turn calls ath12k_regd_update(). By this time, hardware state is on and consecutively ah->regd_updated becomes true. Later, when the 11D scan completes and a new regulatory domain is received from the firmware, the host attempts to update cfg80211 again via ath12k_regd_update(). But since ah->regd_updated is already true, the update is skipped. >From the user's perspective, this results in a failure to connect to 6 GHz APs, as the default regulatory domain (the only one pushed to cfg80211) does not include 6 GHz support. To resolve this, reset the ah->regd_updated flag when handling the 11D regulatory domain update.

2025-05-21tools: ynl-gen: support passing selector to a nestJakub Kicinski
In rtnetlink all submessages had the selector at the same level of nesting as the submessage. We could refer to the relevant attribute from the current struct. In TC, stats are one level of nesting deeper than "kind". Teach the code-gen about structs which need to be passed a selector by the caller for parsing. Because structs are "topologically sorted" one pass of propagating the selectors down is enough. For generating netlink message we depend on the presence bits so no selector passing needed there.

All attribute sets and messages are prefixed with tc-. The C codegen also adds the family name to all structs. We end up with names like struct tc_tc_act_attrs. Remove the tc- prefixes to shorten the names. This should not impact Python as the attr set names are never exposed to user, they are only used to refer to things internally, in the encoder / decoder.

There is a define in the uAPI header called tc_gen which expands to the "generic" TC action fields. This helps other actions include the base fields without having to deal with nested structs. A couple of actions (sample, gact) do not define extra fields, so the spec used a common tc-gen struct for both of them. Unfortunately this struct does not exist in C. Let's use gact's (generic act's) struct for basic actions.

2025-05-21selftests: can: Import tst-filter from can-testsFelix Maurer
Tests for the can subsystem have been in the can-tests repository[1] so far. Start moving the tests to kernel selftests by importing the current tst-filter test. The test is now named test_raw_filter and is substantially updated to be more aligned with the kernel selftests, follow the coding style, and simplify the validation of received CAN frames. We also include documentation of the test design. The test verifies that the single filters on raw CAN sockets work as expected. We intend to import more tests from can-tests and add additional test cases in the future. The goal of moving the CAN selftests into the tree is to align the tests more closely with the kernel, improve testing of CAN in general, and to simplify running the tests automatically in the various kernel CI systems.

2025-05-21Bluetooth: separate CIS_LINK and BIS_LINK link typesPauli Virtanen
Use separate link type id for unicast and broadcast ISO connections. These connection types are handled with separate HCI commands, socket API is different, and hci_conn has union fields that are different in the two cases, so they shall not be mixed up. Currently in most places it is attempted to distinguish ucast by bacmp(&c->dst, BDADDR_ANY) but it is wrong as dst is set for bcast sink hci_conn in iso_conn_ready(). Additionally checking sync_handle might be OK, but depends on details of bcast conn configuration flow. To avoid complicating it, use separate link types.

Up until now it has been assumed that the application would be able to enter the advertising SID in sockaddr_iso_bc.bc_sid, but userspace has no access to SID since the likes of MGMT_EV_DEVICE_FOUND cannot carry it, so it was left unset (0x00) which means it would be unable to synchronize if the broadcast source is using a different SID e.g. 0x04: > HCI Event: LE Meta Event (0x3e) plen 57 LE Extended Advertising Report (0x0d) Num reports: 1 Entry 0 Event type: 0x0000 Props: 0x0000 Data status: Complete Address type: Random (0x01) Address: 0B:82:E8:50:6D:C8 (Non-Resolvable) Primary PHY: LE 1M Secondary PHY: LE 2M SID: 0x04 TX power: 127 dBm RSSI: -55 dBm (0xc9) Periodic advertising interval: 180.00 msec (0x0090) Direct address type: Public (0x00) Direct address: 00:00:00:00:00:00 (OUI 00-00-00) Data length: 0x1f 06 16 52 18 5b 0b e1 05 16 56 18 04 00 11 30 4c ..R.[....V....0L 75 69 7a 27 73 20 53 32 33 20 55 6c 74 72 61 uiz's S23 Ultra Service Data: Broadcast Audio Announcement (0x1852) Broadcast ID: 14748507 (0xe10b5b) Service Data: Public Broadcast Announcement (0x1856) Data[2]: 0400 Unknown EIR field 0x30[16]: 4c75697a27732053323320556c747261 < HCI Command: LE Periodic Advertising Create Sync (0x08|0x0044) plen 14 Options: 0x0000 Use advertising SID, Advertiser Address Type and address Reporting initially enabled SID: 0x00 (<- Invalid) Adv address type: Random (0x01) Adv address: 0B:82:E8:50:6D:C8 (Non-Resolvable) Skip: 0x0000 Sync timeout: 20000 msec (0x07d0) Sync CTE type: 0x0000 So instead this changes now allow application to set HCI_SID_INVALID which will make hci_le_pa_create_sync to wait for a report, update the conn->sid using the report SID and only then issue PA create sync command: < HCI Command: LE Periodic Advertising Create Sync Options: 0x0000 Use advertising SID, Advertiser Address Type and address Reporting initially enabled SID: 0x04 Adv address type: Random (0x01) Adv address: 0B:82:E8:50:6D:C8 (Non-Resolvable) Skip: 0x0000 Sync timeout: 20000 msec (0x07d0) Sync CTE type: 0x0000 > HCI Event: LE Meta Event (0x3e) plen 16 LE Periodic Advertising Sync Established (0x0e) Status: Success (0x00) Sync handle: 64 Advertising SID: 0x04 Advertiser address type: Random (0x01) Advertiser address: 0B:82:E8:50:6D:C8 (Non-Resolvable) Advertiser PHY: LE 2M (0x02) Periodic advertising interval: 180.00 msec (0x0090) Advertiser clock accuracy: 0x05 Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This patch doesn't work quite well - It's observed that with this patch HFP is flaky on most of the existing USB Bluetooth controllers: Intel chips sometimes send out no packet for Transparent codec; MTK chips may generate SCO data with a wrong handle for CVSD codec; RTK could split the data with a wrong packet size for Transparent codec; ... etc. Cc: chromeos-bluetooth-upstreaming@chromium.org Signed-off-by: Hsin-chen Chuang <chharry@chromium.org> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
2025-05-21Bluetooth: btusb: Add HCI Drv commands for configuring altsettingHsin-chen Chuang
Although commit 75ddcd5ad40e ("Bluetooth: btusb: Configure altsetting for HCI_USER_CHANNEL") has enabled the HCI_USER_CHANNEL user to send out SCO data through USB Bluetooth chips, it's observed that with the patch HFP is flaky on most of the existing USB Bluetooth controllers: Intel chips sometimes send out no packet for Transparent codec; MTK chips may generate SCO data with a wrong handle for CVSD codec; RTK could split the data with a wrong packet size for Transparent codec; ... etc. To address the issue above one needs to reset the altsetting back to zero when there is no active SCO connection, which is the same as the BlueZ behavior, and another benefit is the bus doesn't need to reserve bandwidth when no SCO connection. This patch adds "Supported Altsettings" and "Switch Altsetting" commands that allow the user space program to configure the altsetting freely. This patch is tested on ChromeOS devices. The USB Bluetooth models (CVSD, TRANS alt3, and TRANS alt6) could pass the stress HFP test narrow band speech and wide band speech.

2025-05-21Bluetooth: Introduce HCI Driver protocolHsin-chen Chuang
Although commit 75ddcd5ad40e ("Bluetooth: btusb: Configure altsetting for HCI_USER_CHANNEL") has enabled the HCI_USER_CHANNEL user to send out SCO data through USB Bluetooth chips, it's observed that with the patch HFP is flaky on most of the existing USB Bluetooth controllers: Intel chips sometimes send out no packet for Transparent codec; MTK chips may generate SCO data with a wrong handle for CVSD codec; RTK could split the data with a wrong packet size for Transparent codec; ... etc. To address the issue above one needs to reset the altsetting back to zero when there is no active SCO connection, which is the same as the BlueZ behavior, and another benefit is the bus doesn't need to reserve bandwidth when no SCO connection. This patch adds the infrastructure that allow the user space program to talk to Bluetooth drivers directly: - Define the new packet type HCI_DRV_PKT which is specifically used for communication between the user space program and the Bluetooth drviers - hci_send_frame intercepts the packets and invokes drivers' HCI Drv callbacks (so far only defined for btusb) - 2 kinds of events to user space: Command Status and Command Complete, the former simply returns the status while the later may contain additional response data.

This implements host wakeup feature by reading the device tree property wakeup-source and 'wakeup' interrupt, and nxp,wakeout-pin, and configuring it as a FALLING EDGE triggered interrupt. When host is suspended, a trigger from the WAKE_OUT pin of the controller wakes it up. To enable this feature, both device tree properties are needed to be defined.
