2025-03-15bpf/helpers: Introduce bpf_dynptr_copy kfuncMykyta Yatsenko
Introducing bpf_dynptr_copy kfunc allowing copying data from one dynptr to another. This functionality is useful in scenarios such as capturing XDP data to a ring buffer. The implementation consists of 4 branches: * A fast branch for contiguous buffer capacity in both source and destination dynptrs * 3 branches utilizing __bpf_dynptr_read and __bpf_dynptr_write to copy data to/from non-contiguous buffer Signed-off-by: Mykyta Yatsenko <yatsenko@meta.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20250226183201.332713-3-mykyta.yatsenko5@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

Instead of testing the controller register address to distinguish controller 1 from controller 0 on i.MX8MQ platforms, use the PCI domain number, which comes from the devicetree 'linux,pci-domain' property. All relevant devicetrees should already supply 'linux,pci-domain', which was added by c0b70f05c87f ("arm64: dts: imx8mq: use_dt_domains for pci node").

2025-03-15arm64: dts: rockchip: remove ethm0_clk0_25m_out from Sige5 gmac0Nicolas Frattaroli
The GPIO3 A4 pin on the ArmSoM Sige5 is routed to the 40-pin GPIO header. This pin can serve a variety of functions, including ones of questionable use to us on a GPIO header such as the 25MHz clock of the ethernet controller. Unfortunately, this is the precise function that it is being claimed for by the gmac0 node in the Sige5 board dts, meaning it can't be used for anything else despite serving no useful function in this role. Since it goes through a RS0108 bidirectional voltage level translator with a maximum data rate of 24Mbit/s in push-pull mode and 2Mbit/s data rate in open-drain mode, it's doubtful as to whether the 25MHz clock signal would even survive to the actual user-accessible pin it terminates in. Remove it to leave the pin for users to play with. It's infinitely more useful as a GPIO or even as a PWM.

2025-03-15ALSA: hda/realtek: Always honor no_shutup_pinsTakashi Iwai
The workaround for Dell machines to skip the pin-shutup for mic pins introduced alc_headset_mic_no_shutup() that is replaced from the generic snd_hda_shutup_pins() for certain codecs. The problem is that the call is done unconditionally even if spec->no_shutup_pins is set. This seems causing problems on other platforms like Lenovo. This patch corrects the behavior and the driver honors always spec->no_shutup_pins flag and skips alc_headset_mic_no_shutup() if it's set.

2025-03-15m68k/nommu: stop using GENERIC_IOMAPArnd Bergmann
There is no need to go through the GENERIC_IOMAP wrapper for PIO on nommu platforms, since these always come from PCI I/O space that is itself memory mapped. Instead, the generic ioport_map() can just return the MMIO location of the ports directly by applying the PCI_IO_PA offset, while ioread32/iowrite32 trivially turn into readl/writel as they do on most other architectures. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2025-03-15mips: drop GENERIC_IOMAP wrapperArnd Bergmann
All PIO on MIPS platforms is memory mapped, so there is no benefit in the lib/iomap.c wrappers that switch between inb/outb and readb/writeb style accessses. In fact, the '#define PIO_RESERVED 0' setting completely disables the GENERIC_IOMAP functionality, and the '#define PIO_OFFSET mips_io_port_base' setting is based on a misunderstanding of what the offset is meant to do. MIPS started using GENERIC_IOMAP in 2018 with commit b962aeb02205 ("MIPS: Use GENERIC_IOMAP") replacing a simple custom implementation of the same interfaces, but at the time the asm-generic/io.h version was not usable yet. Since the header is now always included, it's now possible to go back to the even simpler version. Use the normal GENERIC_PCI_IOMAP functionality for all mips platforms without the hacky GENERIC_IOMAP, and provide a custom pci_iounmap() for the CONFIG_PCI_DRIVERS_LEGACY case to ensure the I/O port base never gets unmapped. The readsl() prototype needs an extra 'const' keyword to make it compatible with the generic ioread32_rep() alias. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2025-03-15Revert "sched/core: Reduce cost of sched_move_task when config autogroup"Dietmar Eggemann
This reverts commit eff6c8ce8d4d7faef75f66614dd20bb50595d261. Hazem reported a 30% drop in UnixBench spawn test with commit eff6c8ce8d4d ("sched/core: Reduce cost of sched_move_task when config autogroup") on a m6g.xlarge AWS EC2 instance with 4 vCPUs and 16 GiB RAM (aarch64) (single level MC sched domain): https://lkml.kernel.org/r/20250205151026.13061-1-hagarhem@amazon.com There is an early bail from sched_move_task() if p->sched_task_group is equal to p's 'cpu cgroup' (sched_get_task_group()). E.g. both are pointing to taskgroup '/user.slice/user-1000.slice/session-1.scope' (Ubuntu '22.04.5 LTS'). So in: do_exit() sched_autogroup_exit_task() sched_move_task() if sched_get_task_group(p) == p->sched_task_group return /* p is enqueued */ dequeue_task() \ sched_change_group() | task_change_group_fair() | detach_task_cfs_rq() | (1) set_task_rq() | attach_task_cfs_rq() | enqueue_task() / (1) isn't called for p anymore. Turns out that the regression is related to sgs->group_util in group_is_overloaded() and group_has_capacity(). If (1) isn't called for all the 'spawn' tasks then sgs->group_util is ~900 and sgs->group_capacity = 1024 (single CPU sched domain) and this leads to group_is_overloaded() returning true (2) and group_has_capacity() false (3) much more often compared to the case when (1) is called. I.e. there are much more cases of 'group_is_overloaded' and 'group_fully_busy' in WF_FORK wakeup sched_balance_find_dst_cpu() which then returns much more often a CPU != smp_processor_id() (5). This isn't good for these extremely short running tasks (FORK + EXIT) and also involves calling sched_balance_find_dst_group_cpu() unnecessary (single CPU sched domain). Instead if (1) is called for 'p->flags & PF_EXITING' then the path (4),(6) is taken much more often. select_task_rq_fair(..., wake_flags = WF_FORK) cpu = smp_processor_id() new_cpu = sched_balance_find_dst_cpu(..., cpu, ...) group = sched_balance_find_dst_group(..., cpu) do { update_sg_wakeup_stats() sgs->group_type = group_classify() if group_is_overloaded() (2) return group_overloaded if !group_has_capacity() (3) return group_fully_busy return group_has_spare (4) } while group if local_sgs.group_type > idlest_sgs.group_type return idlest (5) case group_has_spare: if local_sgs.idle_cpus >= idlest_sgs.idle_cpus return NULL (6) Unixbench Tests './Run -c 4 spawn' on: (a) VM AWS instance (m7gd.16xlarge) with v6.13 ('maxcpus=4 nr_cpus=4') and Ubuntu 22.04.5 LTS (aarch64).

Herbert asks for long-term maintenance of everything under crypto/asymmetric_keys/ and associated algorithms (ECDSA, GOST, RSA) [1]. Ignat has kindly agreed to co-maintain this with me going forward. Stefan has agreed to be added as reviewer for ECDSA. He introduced it in 2021 and has been meticulously providing reviews for 3rd party patches anyway. Retain David Howells' maintainer entry until he explicitly requests to be removed. He originally introduced asymmetric keys in 2012. RSA was introduced by Tadeusz Struk as an employee of Intel in 2015, but he's changed jobs and last contributed to the implementation in 2016. GOST was introduced by Vitaly Chikunov as an employee of Basealt LLC [2] (Базальт СПО [3]) in 2019. This company is an OFAC sanctioned entity [4][5], which makes employees ineligible as maintainer [6]. It's not clear if Vitaly is still working for Basealt, he did not immediately respond to my e-mail. Since knowledge and use of GOST algorithms is relatively limited outside the Russian Federation, assign "Odd fixes" status for now.

2025-03-14perf test: Add pipe output testing for annotateIan Rogers
Parameterize the basic testing to generate directly a perf.data file or to generate/use one from pipe input or output. To simplify the refactor move some of the head/grep logic around. Use "-q" with grep to make the test output cleaner.

2025-03-14perf test: Fixes to variable expansion and stdout for diff testIan Rogers
When make_data fails its error message needs to go to stderr rather than stdout and the stdout value is captured in a variable. Quote the $err value so that it is always a valid input for test. This error is commonly encountered if no sample data is gathered by the test.
