Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "Not much excitement - a handful of large patchsets (devmem among them) did not make it in time. Core & protocols: - Use local_lock in addition to local_bh_disable() to protect per-CPU resources in networking, a step closer for local_bh_disable() not to act as a big lock on PREEMPT_RT - Use flex array for netdevice priv area, ensure its cache alignment - Add a sysctl knob to allow user to specify a default rto_min at socket init time. Bit of a big hammer but multiple companies were independently carrying such patch downstream so clearly it's useful - Support scheduling transmission of packets based on CLOCK_TAI - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off using cpusets - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address - Allow configuration of multipath hash seed, to both allow synchronizing hashing of two routers, and preventing partial accidental sync - Improve TCP compliance with RFC 9293 for simultaneous connect() - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace IKE daemon had to do this before, but the kernel can better keep track of it - Support sending supervision HSR frames with MAC addresses stored in ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled - Introduce IPPROTO_SMC for selecting SMC when socket is created - Allow UDP GSO transmit from devices with no checksum offload - openvswitch: add packet sampling via psample, separating the sampled traffic from "upcall" packets sent to user space for forwarding - nf_tables: shrink memory consumption for transaction objects Things we sprinkled into general kernel code: - Power Sequencing subsystem (used by Qualcomm Bluetooth driver for QCA6390) [ Already merged separately - Linus ] - Add IRQ information in sysfs for auxiliary bus - Introduce guard definition for local_lock - Add aligned flavor of __cacheline_group_{begin, end}() markings for grouping fields in structures BPF: - Notify user space (via epoll) when a struct_ops object is getting detached/unregistered - Add new kfuncs for a generic, open-coded bits iterator - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and bpf_list_head - Support resilient split BTF which cuts down on duplication and makes BTF as compact as possible WRT BTF from modules - Add support for dumping kfunc prototypes from BTF which enables both detecting as well as dumping compilable prototypes for kfuncs - riscv64 BPF JIT improvements in particular to add 12-argument support for BPF trampolines and to utilize bpf_prog_pack for the latter - Add the capability to offload the netfilter flowtable in XDP layer through kfuncs Driver API: - Allow users to configure IRQ tresholds between which automatic IRQ moderation can choose - Expand Power Sourcing (PoE) status with power, class and failure reason. Support setting power limits - Track additional RSS contexts in the core, make sure configuration changes don't break them - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP data paths -

Merge tag 'aux-sysfs-irqs' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linuxSaeed Mahameed says:====================aux-sysfs-irqsShay Says:==========Introduce auxiliary bus IRQs sysfsToday, PCI PFs and VFs, which are anchored on the PCI bus, display theirIRQ information in the /msi_irqs/ sysfs files. PCIsubfunctions (SFs) are similar to PFs and VFs and these SFs are anchoredon the auxiliary bus. However, these PCI SFs lack such IRQ informationon the auxiliary bus, leaving users without visibility into which IRQsare used by the SFs. This absence makes it impossible to debugsituations and to understand the source of interrupts/SFs forperformance tuning and debug.Additionally, the SFs are multifunctional devices supporting RDMA,network devices, clocks, and more, similar to their peer PCI PFs andVFs. Therefore, it is desirable to have SFs' IRQ information availableat the bus/device level.To overcome the above limitations, this short series extends theauxiliary bus to display IRQ information in sysfs, similar to that ofPFs and VFs.It adds an 'irqs' directory under the auxiliary device and includes an sysfs file within it.For example:$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/50 51 52 53 54 55 56 57 58Patch summary:patch-1 adds auxiliary bus to support irqs used by auxiliary devicepatch-2 mlx5 driver using exposing irqs for PCI SF devices via auxiliary bus==========* tag 'aux-sysfs-irqs' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux: net/mlx5: Expose SFs IRQs driver core: auxiliary bus: show auxiliary device IRQs RDMA/mlx5: Add Qcounters req_transport_retries_exceeded/req_rnr_retries_exceeded net/mlx5: Reimplement write combining test====================Link: https://patch.msgid.link/20240711213140.256997-1-saeed@kernel.orgSigned-off-by: Jakub Kicinski List of files: /linux/Documentation/ABI/testing/sysfs-bus-auxiliary

a808878308a8041ae10a151d69e2d22f94cae9f4 - driver core: auxiliary bus: show auxiliary device IRQs

Sun, 14 Apr 2024 10:05:25 +0200

driver core: auxiliary bus: show auxiliary device IRQsPCI subfunctions (SF) are anchored on the auxiliary bus. PCI physicaland virtual functions are anchored on the PCI bus. The irq informationof each such function is visible to users via sysfs directory "msi_irqs"containing files for each irq entry. However, for PCI SFs suchinformation is unavailable. Due to this users have no visibility on IRQsused by the SFs.Secondly, an SF can be multi function device supporting rdma, netdeviceand more. Without irq information at the bus level, the user is unableto view or use the affinity of the SF IRQs.Hence to match to the equivalent PCI PFs and VFs, add "irqs" directory,for supporting auxiliary devices, containing file for each irq entry.For example:$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/50 51 52 53 54 55 56 57 58Cc: Simon Horman Reviewed-by: Przemek Kitszel Reviewed-by: Parav Pandit Reviewed-by: Greg Kroah-Hartman Signed-off-by: Shay Drory Signed-off-by: Saeed Mahameed ---v9-v10:- remove Przemek RB- add name field to auxiliary_irq_info (Greg and Przemek)- handle bogus IRQ in auxiliary_device_sysfs_irq_remove (Greg)v8-v9:- add Przemek RB- use guard() in auxiliary_irq_dir_prepare (Paolo)v7-v8:- use cleanup.h for info and name fields (Greg)- correct error flow in auxiliary_irq_dir_prepare (Przemek)- add documentation for new fields of auxiliary_device (Simon)v6-v7:- dynamically creating irqs directory when first irq file created (Greg)- removed irqs flag and simplified the dev_add() API (Greg)- move sysfs related new code to a new auxiliary_sysfs.c file (Greg)v5-v6:- removed concept of shared and exclusive and hence global xarray (Greg)v4-v5:- restore global mutex and replace refcount_t with simple integer (Greg)v3->4:- remove global mutex (Przemek)v2->v3:- fix function declaration in case SYSFS isn't definedv1->v2:- move #ifdefs from drivers/base/auxiliary.c to include/linux/auxiliary_bus.h (Greg)- use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL (Greg)- Fix kzalloc(ref) to kzalloc(*ref) (Simon)- Add return description in auxiliary_device_sysfs_irq_add() kdoc (Simon)- Fix auxiliary_irq_mode_show doc (kernel test boot) List of files: /linux/Documentation/ABI/testing/sysfs-bus-auxiliary
