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.

2024-01-11scsi: core: Kick the requeue list after inserting when flushingNiklas Cassel
When libata calls ata_link_abort() to abort all ata queued commands, it calls blk_abort_request() on the SCSI command representing each QC. This causes scsi_timeout() to be called, which calls scsi_eh_scmd_add() for each SCSI command. scsi_eh_scmd_add() sets the SCSI host to state recovery, and then adds the command to shost->eh_cmd_q. This will wake up the SCSI EH, and eventually the libata EH strategy handler will be called, which calls scsi_eh_flush_done_q() to either flush retry or flush finish each failed command. The commands that are flush retried by scsi_eh_flush_done_q() are done so using scsi_queue_insert(). Before commit 8b566edbdbfb ("scsi: core: Only kick the requeue list if necessary"), __scsi_queue_insert() called blk_mq_requeue_request() with the second argument set to true, indicating that it should always kick/run the requeue list after inserting. After commit 8b566edbdbfb ("scsi: core: Only kick the requeue list if necessary"), __scsi_queue_insert() does not kick/run the requeue list after inserting, if the current SCSI host state is recovery (which is the case in the libata example above). This optimization is probably fine in most cases, as I can only assume that most often someone will eventually kick/run the queues. However, that is not the case for scsi_eh_flush_done_q(), where we can see that the request gets inserted to the requeue list, but the queue is never started after the request has been inserted, leading to the block layer waiting for the completion of command that never gets to run. Since scsi_eh_flush_done_q() is called by SCSI EH context, the SCSI host state is most likely always in recovery when this function is called. Thus, let scsi_eh_flush_done_q() explicitly kick the requeue list after inserting a flush retry command, so that scsi_eh_flush_done_q() keeps the same behavior as before commit 8b566edbdbfb ("scsi: core: Only kick the requeue list if necessary").

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.

2024-01-11media: i2c: thp7312: select CONFIG_FW_LOADERArnd Bergmann
The recently added driver uses the firmware loader mechanism but causes a link failure when that is in a loadable module while thp7312 itself is built-in: arm-linux-gnueabi-ld: drivers/media/i2c/thp7312.o: in function `thp7312_probe': thp7312.c:(.text+0x4164): undefined reference to `firmware_upload_register' Select the required Kconfig symbol. Note that the driver specifically needs the firmware upload interface that is controlled by CONFIG_FW_UPLOAD, but there is no link failure when that is disabled because the interfaces are stubbed out here.

In nested translation, the stage-1 page table is user-managed but cached by the IOMMU hardware, so an update on present page table entries in the stage-1 page table should be followed with a cache invalidation. Add an IOMMU_HWPT_INVALIDATE ioctl to support such a cache invalidation. It takes hwpt_id to specify the iommu_domain, and a multi-entry array to support multiple invalidation data in one ioctl. enum iommu_hwpt_invalidate_data_type is defined to tag the data type of the entries in the multi-entry array.
