ctlr->mode is of unsigned type, it is never less than zero. Fix this by using an extra variable called 'res', to store return value from sysfs_match_string() and assign that to ctlr->mode on the success path.

2024-01-11amt: do not use overwrapped cb areaTaehee Yoo1-3/+3
amt driver uses skb->cb for storing tunnel information. This job is worked before TC layer and then amt driver load tunnel info from skb->cb after TC layer. So, its cb area should not be overwrapped with CB area used by TC. In order to not use cb area used by TC, it skips the biggest cb structure used by TC, which was qdisc_skb_cb. But it's not anymore. Currently, biggest structure of TC's CB is tc_skb_cb. So, it should skip size of tc_skb_cb instead of qdisc_skb_cb.

2024-01-11net: ethernet: ti: am65-cpsw: Fix max mtu to fit ethernet framesSanjuán García, Jorge1-2/+3
The value of AM65_CPSW_MAX_PACKET_SIZE represents the maximum length of a received frame. This value is written to the register AM65_CPSW_PORT_REG_RX_MAXLEN. The maximum MTU configured on the network device should then leave some room for the ethernet headers and frame check. Otherwise, if the network interface is configured to its maximum mtu possible, the frames will be larger than AM65_CPSW_MAX_PACKET_SIZE and will get dropped as oversized. The switch supports ethernet frame sizes between 64 and 2024 bytes (including VLAN) as stated in the technical reference manual, so define AM65_CPSW_MAX_PACKET_SIZE with that maximum size.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "The most interesting thing is probably the networking structs reorganization and a significant amount of changes is around self-tests. Core & protocols: - Analyze and reorganize core networking structs (socks, netdev, netns, mibs) to optimize cacheline consumption and set up build time warnings to safeguard against future header changes This improves TCP performances with many concurrent connections up to 40% - Add page-pool netlink-based introspection, exposing the memory usage and recycling stats. This helps indentify bad PP users and possible leaks - Refine TCP/DCCP source port selection to no longer favor even source port at connect() time when IP_LOCAL_PORT_RANGE is set. This lowers the time taken by connect() for hosts having many active connections to the same destination - Refactor the TCP bind conflict code, shrinking related socket structs - Refactor TCP SYN-Cookie handling, as a preparation step to allow arbitrary SYN-Cookie processing via eBPF - Tune optmem_max for 0-copy usage, increasing the default value to 128KB and namespecifying it - Allow coalescing for cloned skbs coming from page pools, improving RX performances with some common configurations - Reduce extension header parsing overhead at GRO time - Add bridge MDB bulk deletion support, allowing user-space to request the deletion of matching entries - Reorder nftables struct members, to keep data accessed by the datapath first - Introduce TC block ports tracking and use. This allows supporting multicast-like behavior at the TC layer - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and classifiers (RSVP and tcindex) - More data-race annotations - Extend the diag interface to dump TCP bound-only sockets - Conditional notification of events for TC qdisc class and actions - Support for WPAN dynamic associations with nearby devices, to form a sub-network using a specific PAN ID - Implement SMCv2.1 virtual ISM device support - Add support for Batman-avd mulicast packet type BPF: - Tons of verifier improvements: - BPF register bounds logic and range support along with a large test suite - log improvements - complete precision tracking support for register spills - track aligned STACK_ZERO cases as imprecise spilled registers. This improves the verifier "instructions processed" metric from single digit to 50-60% for some programs - support for user's global BPF subprogram arguments with few commonly requested annotations for a better developer experience - support tracking of BPF_JNE which helps cases when the compiler transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the like - several fixes - Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload - Fix kCFI bugs in BPF all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y - Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques - Support uid/gid options when mounting bpffs - Add a new kfunc which acquires the associated cgroup of a task within a specific cgroup v1 hierarchy where the latter is identified by its id - Extend verifier to allow bpf_refcount_acquire() of a map value field obtained via direct load which is a use-case needed in sched_ext - Add BPF link_info support for uprobe multi link along with bpftool integration for the latter - Support for VLAN tag in XDP hints - Remove deprecated bpfilter kernel leftovers given the project is developed in user-space (https://github.com/facebook/bpfilter) Misc: - Support for parellel TC self-tests execution - Increase MPTCP self-tests coverage - Updated the bridge documentation, including several so-far undocumented features - Convert all the net self-tests to run in unique netns, to avoid random failures due to conflict and allow concurrent runs - Add TCP-AO self-tests - Add kunit tests for both cfg80211 and mac80211 - Autogenerate Netlink families documentation from YAML spec - Add yml-gen support for fixed headers and recursive nests, the tool can now generate user-space code for all genetlink families for which we have specs - A bunch of additional module descriptions fixes - Catch incorrect freeing of pages belonging to a page pool Driver API: - Rust abstractions for network PHY drivers; do not cover yet the full C API, but already allow implementing functional PHY drivers in rust - Introduce queue and NAPI support in the netdev Netlink interface, allowing complete access to the device <> NAPIs <> queues relationship - Introduce notifications filtering for devlink to allow control application scale to thousands of instances - Improve PHY validation, requesting rate matching information for each ethtool link mode supported by both the PHY and host - Add support for ethtool symmetric-xor RSS hash - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD platform - Expose pin fractional frequency offset value over new DPLL generic netlink attribute - Convert older drivers to platform remove callback returning void - Add support for PHY package MMD read/write New hardware / drivers: - Ethernet: - Octeon CN10K devices - Broadcom 5760X P7 - Qualcomm SM8550 SoC - Texas Instrument DP83TG720S PHY - Bluetooth: - IMC Networks Bluetooth radio Removed: - WiFi: - libertas 16-bit PCMCIA support - Atmel at76c50x drivers - HostAP ISA/PCMCIA style 802.11b driver - zd1201 802.11b USB dongles - Orinoco ISA/PCMCIA 802.11b driver - Aviator/Raytheon driver - Planet WL3501 driver - RNDIS USB 802.11b driver Driver updates: - Ethernet high-speed NICs: - Intel (100G, ice, idpf): - allow one by one port representors creation and removal - add temperature and clock information reporting - add get/set for ethtool's header split ringparam - add again FW logging - adds support switchdev hardware packet mirroring - iavf: implement symmetric-xor RSS hash - igc: add support for concurrent physical and free-running timers - i40e: increase the allowable descriptors - nVidia/Mellanox: - Preparation for Socket-Direct multi-dev netdev.

2024-01-11PCI: brcmstb: Configure HW CLKREQ# mode appropriate for downstream deviceJim Quinlan1-10/+86
The Broadcom STB/CM PCIe HW core, which is also used in RPi SOCs, must be deliberately set by the PCIe RC HW into one of three mutually exclusive modes: "safe" -- No CLKREQ# expected or required, refclk is always provided. This mode should work for all devices but is not be capable of any refclk power savings. "no-l1ss" -- CLKREQ# is expected to be driven by the downstream device for CPM and ASPM L0s and L1. Provides Clock Power Management, L0s, and L1, but cannot provide L1 substate (L1SS) power savings. If the downstream device connected to the RC is L1SS capable AND the OS enables L1SS, all PCIe traffic may abruptly halt, potentially hanging the system. "default" -- Bidirectional CLKREQ# between the RC and downstream device. Provides ASPM L0s, L1, and L1SS, but not compliant to provide Clock Power Management; specifically, may not be able to meet the T_CLRon max timing of 400ns as specified in "Dynamic Clock Control", section 3.2.5.2.2 of the PCIe Express Mini CEM 2.1 specification. This situation is atypical and should happen only with older devices. Previously, this driver always set the mode to "no-l1ss", as almost all STB/CM boards operate in this mode. But now there is interest in activating L1SS power savings from STB/CM customers, which requires "aspm" mode. In addition, a bug was filed for RPi4 CM platform because most devices did not work in "no-l1ss" mode. Note that the mode is specified by the DT property "brcm,clkreq-mode". If this property is omitted, then "default" mode is chosen. Note: Since L1 substates are now possible, a modification was made regarding an internal bus timeout: During long periods of the PCIe RC HW being in an L1SS sleep state, there may be a timeout on an internal bus access, even though there may not be any PCIe access involved. Such a timeout will cause a subsequent CPU abort.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Add machine variable capacity information to /proc/sysinfo. - Limit the waste of page tables and always align vmalloc area size and base address on segment boundary. - Fix a memory leak when an attempt to register interruption sub class (ISC) for the adjunct-processor (AP) guest failed. - Reset response code AP_RESPONSE_INVALID_GISA to understandable by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed interruption sub class (ISC) registration attempt. - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts on behalf of a guest. - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue device bound to the vfio_ap device driver when the mediated device is attached to a guest, but the queue device is not passed through. - Rework struct ap_card to hold the whole adjunct-processor (AP) card hardware information. As result, all the ugly bit checks are replaced by simple evaluations of the required bit fields. - Improve handling of some weird scenarios between service element (SE) host and SE guest with adjunct-processor (AP) pass-through support. - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the previous value of the to be changed control register. This is useful if a bit is only changed temporarily and the previous content needs to be restored. - The kernel starts with machine checks disabled and is expected to enable it once trap_init() is called. However the implementation allows machine checks early. Consistently enable it in trap_init() only. - local_mcck_disable() and local_mcck_enable() assume that machine checks are always enabled. Instead implement and use local_mcck_save() and local_mcck_restore() to disable machine checks and restore the previous state. - Modification of floating point control (FPC) register of a traced process using ptrace interface may lead to corruption of the FPC register of the tracing process. Fix this. - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control (FPC) register in vCPU, but may lead to corruption of the FPC register of the host process. Fix this. - Use READ_ONCE() to read a vCPU floating point register value from the memory mapped area. This avoids that, depending on code generation, a different value is tested for validity than the one that is used. - Get rid of test_fp_ctl(), since it is quite subtle to use it correctly. Instead copy a new floating point control register value into its save area and test the validity of the new value when loading it. - Remove superfluous save_fpu_regs() call. - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines provide the vector facility since many years and the need to make the task structure size dependent on the vector facility does not exist. - Remove the "novx" kernel command line option, as the vector code runs without any problems since many years. - Add the vector facility to the z13 architecture level set (ALS). All hypervisors support the vector facility since many years. This allows compile time optimizations of the kernel. - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As result, the compiled code will have less runtime checks and less code. - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C. - Convert the struct subchannel spinlock from pointer to member. * tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (24 commits) Revert "s390: update defconfigs" s390/cio: make sch->lock spinlock pointer a member s390: update defconfigs s390/mm: convert pgste locking functions to C s390/fpu: get rid of MACHINE_HAS_VX s390/als: add vector facility to z13 architecture level set s390/fpu: remove "novx" option s390/fpu: remove ARCH_WANTS_DYNAMIC_TASK_STRUCT support KVM: s390: remove superfluous save_fpu_regs() call s390/fpu: get rid of test_fp_ctl() KVM: s390: use READ_ONCE() to read fpc register value KVM: s390: fix setting of fpc register s390/ptrace: handle setting of fpc register correctly s390/nmi: implement and use local_mcck_save() / local_mcck_restore() s390/nmi: consistently enable machine checks in trap_init() s390/ctlreg: return old register contents when changing bits s390/ap: handle outband SE bind state change s390/ap: store TAPQ hwinfo in struct ap_card s390/vfio-ap: fix sysfs status attribute for AP queue devices s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC) command ...

2024-01-10vfio/virtio: fix virtio-pci dependencyArnd Bergmann1-1/+1
The new vfio-virtio driver already has a dependency on VIRTIO_PCI_ADMIN_LEGACY, but that is a bool symbol and allows vfio-virtio to be built-in even if virtio-pci itself is a loadable module. This leads to a link failure: aarch64-linux-ld: drivers/vfio/pci/virtio/main.o: in function `virtiovf_pci_probe': main.c:(.text+0xec): undefined reference to `virtio_pci_admin_has_legacy_io' aarch64-linux-ld: drivers/vfio/pci/virtio/main.o: in function `virtiovf_pci_init_device': main.c:(.text+0x260): undefined reference to `virtio_pci_admin_legacy_io_notify_info' aarch64-linux-ld: drivers/vfio/pci/virtio/main.o: in function `virtiovf_pci_bar0_rw': main.c:(.text+0x6ec): undefined reference to `virtio_pci_admin_legacy_common_io_read' aarch64-linux-ld: main.c:(.text+0x6f4): undefined reference to `virtio_pci_admin_legacy_device_io_read' aarch64-linux-ld: main.c:(.text+0x7f0): undefined reference to `virtio_pci_admin_legacy_common_io_write' aarch64-linux-ld: main.c:(.text+0x7f8): undefined reference to `virtio_pci_admin_legacy_device_io_write' Add another explicit dependency on the tristate symbol.

2024-01-10nvmet-rdma: avoid circular locking dependency on install_queue()Hannes Reinecke1-3/+16
nvmet_rdma_install_queue() is driven from the ->io_work workqueue function, but will call flush_workqueue() which might trigger ->release_work() which in itself calls flush_work on ->io_work. To avoid that check for pending queue in disconnecting status, and return 'controller busy' when we reached a certain threshold.

2024-01-10PM: sleep: Restore asynchronous device resume optimizationRafael J. Wysocki1-53/+64
Before commit 7839d0078e0d ("PM: sleep: Fix possible deadlocks in core system-wide PM code"), the resume of devices that were allowed to resume asynchronously was scheduled before starting the resume of the other devices, so the former did not have to wait for the latter unless functional dependencies were present. Commit 7839d0078e0d removed that optimization in order to address a correctness issue, but it can be restored with the help of a new device power management flag, so do that now.
