2025-05-21net: add skb_copy_and_crc32c_datagram_iter()Eric Biggers
Since skb_copy_and_hash_datagram_iter() is used only with CRC32C, the crypto_ahash abstraction provides no value. Add skb_copy_and_crc32c_datagram_iter() which just calls crc32c() directly. This is faster and simpler. It also doesn't have the weird dependency issue where skb_copy_and_hash_datagram_iter() depends on CONFIG_CRYPTO_HASH=y without that being expressed explicitly in the kconfig (presumably because it was too heavyweight for NET to select). The new function is conditional on the hidden boolean symbol NET_CRC32C, which selects CRC32. So it gets compiled only when something that actually needs CRC32C packet checksums is enabled, it has no implicit dependency, and it doesn't depend on the heavyweight crypto layer.

2025-05-21net: fold __skb_checksum() into skb_checksum()Eric Biggers
Now that the only remaining caller of __skb_checksum() is skb_checksum(), fold __skb_checksum() into skb_checksum(). This makes struct skb_checksum_ops unnecessary, so remove that too and simply do the "regular" net checksum. It also makes the wrapper functions csum_partial_ext() and csum_block_add_ext() unnecessary, so remove those too and just use the underlying functions.

2025-05-21net: add skb_crc32c()Eric Biggers
Add skb_crc32c(), which calculates the CRC32C of a sk_buff. It will replace __skb_checksum(), which unnecessarily supports arbitrary checksums. Compared to __skb_checksum(), skb_crc32c(): - Uses the correct type for CRC32C values (u32, not __wsum). - Does not require the caller to provide a skb_checksum_ops struct. - Is faster because it does not use indirect calls and does not use the very slow crc32c_combine(). According to commit 2817a336d4d5 ("net: skb_checksum: allow custom update/combine for walking skb") which added __skb_checksum(), the original motivation for the abstraction layer was to avoid code duplication for CRC32C and other checksums in the future. However: - No additional checksums showed up after CRC32C. __skb_checksum() is only used with the "regular" net checksum and CRC32C. - Indirect calls are expensive. Commit 2544af0344ba ("net: avoid indirect calls in L4 checksum calculation") worked around this using the INDIRECT_CALL_1 macro. But that only avoided the indirect call for the net checksum, and at the cost of an extra branch. - The checksums use different types (__wsum and u32), causing casts to be needed. - It made the checksums of fragments be combined (rather than chained) for both checksums, despite this being highly counterproductive for CRC32C due to how slow crc32c_combine() is. This can clearly be seen in commit 4c2f24549644 ("sctp: linearize early if it's not GSO") which tried to work around this performance bug. With a dedicated function for each checksum, we can instead just use the proper strategy for each checksum. As shown by the following tables, the new function skb_crc32c() is faster than __skb_checksum(), with the improvement varying greatly from 5% to 2500% depending on the case. The largest improvements come from fragmented packets, mainly due to eliminating the inefficient crc32c_combine(). But linear packets are improved too, especially shorter ones, mainly due to eliminating indirect calls. These benchmarks were done on AMD Zen 5. On that CPU, Linux uses IBRS instead of retpoline; an even greater improvement might be seen with retpoline: Linear sk_buffs Length in bytes __skb_checksum cycles skb_crc32c cycles =============== ===================== ================= 64 43 18 256 94 77 1420 204 161 16384 1735 1642 Nonlinear sk_buffs (even split between head and one fragment) Length in bytes __skb_checksum cycles skb_crc32c cycles =============== ===================== ================= 64 579 22 256 829 77 1420 1506 194 16384 4365 1682 Signed-off-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Hannes Reinecke <hare@suse.de> Link: https://patch.msgid.link/20250519175012.36581-3-ebiggers@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

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.

2025-05-21ALSA: hda - Add new driver for HDA controllers listed via ACPIDaniel Dadap
Some systems expose HD-Audio controllers via objects in the ACPI tables which encapsulate the controller's interrupt and the base address for the HDA registers in an ACPI _CRS object, for example, as listed in this ACPI table dump excerpt: Device (HDA0) { Name (_HID, "NVDA2014") // _HID: Hardware ID ... Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { Memory32Fixed (ReadWrite, 0x36078000, // Address Base 0x00008000, // Address Length ) Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, ) { 0x0000021E, } }) } Add support for HDA controllers discovered through ACPI, including support for some platforms which expose such HDA controllers on NVIDIA SoCs. This is done with a new driver which uses existing infrastructure for extracting resource information from _CRS objects and plumbs the parsed resource information through to the existing HDA infrastructure to enable HD-Audio functionality on such devices. Although this driver is in the sound/pci/hda/ directory, it targets devices which are not actually enumerated on the PCI bus. This is because it depends upon the Intel "Azalia" infrastructure which has traditionally been usedvfor PCI-based devices.

2025-05-21spi: spi-qpic-snand: remove superfluous parameters of qcom_spi_check_error()Gabor Juhos
The qcom_spi_check_error() function determines the errors of a previous page read operation solely by using the cached register values in the register read buffer. The data pointed by the 'data_buf' and the 'oob_buf' parameters are not used for that at all. Remove the superfluous parameters of the function along with the related local variables to simplify the code. Also, remove the variables from the caller functions which became unused due to the change. Note: Althought the similar parse_read_errors() function in the 'qcom_nand' driver has the same parameters, but that function passes down the pointers to check_for_erased_page() at the end of the function. It is not clear, that a similar call is missing here, or the superfluous parameters are simply leftovers of the development process. Nevertheless, if additional code is needed, the parameters can be added back later.

With commit 08699d20467b6 ("sched_ext: idle: Consolidate default idle CPU selection kfuncs") allowing scx_bpf_select_cpu_dfl() to be invoked from multiple contexts, update the test to validate that the kfunc behaves correctly when used from ops.enqueue() and via BPF test_run. Additionally, rename the test to enq_select_cpu, dropping "fails" from the name, as the logic has now been inverted.

2025-05-21sched_ext: idle: Consolidate default idle CPU selection kfuncsAndrea Righi
There is no reason to restrict scx_bpf_select_cpu_dfl() invocations to ops.select_cpu() while allowing scx_bpf_select_cpu_and() to be used from multiple contexts, as both provide equivalent functionality, with the latter simply accepting an additional "allowed" cpumask. Therefore, unify the two APIs, enabling both kfuncs to be used from ops.select_cpu(), ops.enqueue(), and unlocked contexts (e.g., via BPF test_run). This allows schedulers to implement a consistent idle CPU selection policy and helps reduce code duplication. Signed-off-by: Andrea Righi <arighi@nvidia.com> Signed-off-by: Tejun Heo <tj@kernel.org>

2025-05-21Add DAPM/ASoC helpers to create SDCA driversMark Brown
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: Add helper functions to add DAPM widgets, routes, ALSA controls, and DAI drivers, these will be used to create SDCA function device drivers. This series should provide most of the core functionality needed to get a device registered and have a working DAPM graph within the device. There are some features that still need additional work, these are marked with FIXMEs in the code. The two main things are SDCA Clock Muxes (not used in our devices and needs some ASoC core work), and better support for more complex SDCA volume control definitions (our parts have fairly simple volumes, and SDCA has a large amount of flexibility in how the volume control is specified). The next steps in the process are to add helpers for the DAI ops themselves, some IRQ handling, and firmware download. And finally we should be able to actually add the SDCA class driver itself.

2025-05-21selftests: can: test_raw_filter.sh: add support of physical interfacesVincent Mailhol
Allow the user to specify a physical interface through the $CANIF environment variable. Add a $BITRATE environment variable set with a default value of 500000. If $CANIF is omitted or if it starts with vcan (e.g. vcan1), the test will use the virtual can interface type. Otherwise, it will assume that the provided interface is a physical can interface. For example: CANIF=can1 BITRATE=1000000 ./test_raw_filter.sh will run set the can1 interface with a bitrate of one million and run the tests on it.

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.
