2024-01-16wifi: ath12k: relocate ath12k_dp_pdev_pre_alloc() callKarthikeyan Periyasamy
Currently, the data path pdev pre alloc and mac allocate are called separately from the core start procedure. The data path pdev pre alloc can be called from the mac allocate procedure itself since initialization related to pdev happens in the mac allocate procedure. So move the caller of DP pdev pre alloc from the core start procedure to the mac allocate procedure. This change helps in the future to easily decouple the mac allocate procedure from core start handling in order to support MLO in multi chip.

2024-01-14net: ravb: Fix dma_addr_t truncation in error caseNikita Yushchenko
In ravb_start_xmit(), ravb driver uses u32 variable to store result of dma_map_single() call. Since ravb hardware has 32-bit address fields in descriptors, this works properly when mapping is successful - it is platform's job to provide mapping addresses that fit into hardware limitations. However, in failure case dma_map_single() returns DMA_MAPPING_ERROR constant that is 64-bit when dma_addr_t is 64-bit. Storing this constant in u32 leads to truncation, and further call to dma_mapping_error() fails to notice the error. Fix that by storing result of dma_map_single() in a dma_addr_t variable.

But ath11k_reg_chan_list_event() will be called from process context in an upcoming patch, and this can result in a deadlock if ab->base_lock is acquired in process context and then soft IRQ occurs on the same CPU and tries to acquire that lock.

2024-01-12wifi: rtlwifi: rtl_usb: Use sync register writesBitterblue Smith
Currently rtl_usb performs register writes using the async usb_submit_urb() function. This appears to work fine for the RTL8192CU, but the RTL8192DU (soon to be supported by rtlwifi) has a problem: it transmits everything at the 1M rate in the 2.4 GHz band. (The 5 GHz band is still untested.) With this patch, rtl_usb performs the register writes using the synchronous usb_control_msg() function, and the RTL8192DU works normally. The RTL8192CU still works. The vendor drivers use the async writes in only one function, rtl8192du_trigger_gpio_0 / rtl8192cu_trigger_gpio_0, which probably doesn't even run in real life. They use sync writes everywhere else. Also, remove "sync" and "async" from the names of the members of struct rtl_io to avoid confusion: write{8,16,32}_async -> write{8,16,32} read{8,16,32}_sync -> read{8,16,32} Signed-off-by: Bitterblue Smith <rtl8821cerfe2@gmail.com> Acked-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://msgid.link/fb71bae6-8b19-4b6e-b4a6-0d260f2139e1@gmail.com

2024-01-12net: phy: micrel: populate .soft_reset for KSZ9131Claudiu Beznea
The RZ/G3S SMARC Module has 2 KSZ9131 PHYs. In this setup, the KSZ9131 PHY is used with the ravb Ethernet driver. It has been discovered that when bringing the Ethernet interface down/up continuously, e.g., with the following sh script: $ while :; do ifconfig eth0 down; ifconfig eth0 up; done the link speed and duplex are wrong after interrupting the bring down/up operation even though the Ethernet interface is up. To recover from this state the following configuration sequence is necessary (executed manually): $ ifconfig eth0 down $ ifconfig eth0 up The behavior has been identified also on the Microchip SAMA7G5-EK board which runs the macb driver and uses the same PHY. The order of PHY-related operations in ravb_open() is as follows: ravb_open() -> ravb_phy_start() -> ravb_phy_init() -> of_phy_connect() -> phy_connect_direct() -> phy_attach_direct() -> phy_init_hw() -> phydev->drv->soft_reset() phydev->drv->config_init() phydev->drv->config_intr() phy_resume() kszphy_resume() The order of PHY-related operations in ravb_close is as follows: ravb_close() -> phy_stop() -> phy_suspend() -> kszphy_suspend() -> genphy_suspend() // set BMCR_PDOWN bit in MII_BMCR In genphy_suspend() setting the BMCR_PDWN bit in MII_BMCR switches the PHY to Software Power-Down (SPD) mode (according to the KSZ9131 datasheet). Thus, when opening the interface after it has been previously closed (via ravb_close()), the phydev->drv->config_init() and phydev->drv->config_intr() reach the KSZ9131 PHY driver via the ksz9131_config_init() and kszphy_config_intr() functions. KSZ9131 specifies that the MII management interface remains operational during SPD (Software Power-Down), but (according to manual): - Only access to the standard registers (0 through 31) is supported. - Access to MMD address spaces other than MMD address space 1 is possible if the spd_clock_gate_override bit is set. - Access to MMD address space 1 is not possible. The spd_clock_gate_override bit is not used in the KSZ9131 driver. ksz9131_config_init() configures RGMII delay, pad skews and LEDs by accessesing MMD registers other than those in address space 1. The datasheet for the KSZ9131 does not specify what happens if registers from an unsupported address space are accessed while the PHY is in SPD. To fix the issue the .soft_reset method has been instantiated for KSZ9131, too. This resets the PHY to the default state before doing any configurations to it, thus switching it out of SPD.

2024-01-12net: micrel: Fix PTP frame parsing for lan8841Horatiu Vultur
The HW has the capability to check each frame if it is a PTP frame, which domain it is, which ptp frame type it is, different ip address in the frame. And if one of these checks fail then the frame is not timestamp. Most of these checks were disabled except checking the field minorVersionPTP inside the PTP header. Meaning that once a partner sends a frame compliant to 8021AS which has minorVersionPTP set to 1, then the frame was not timestamp because the HW expected by default a value of 0 in minorVersionPTP. Fix this issue by removing this check so the userspace can decide on this.

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, Jorge
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.
