2025-02-24net: stmmac: thead: ensure divisor gives proper rateRussell King (Oracle)
thead was checking that the stmmac_clk rate was a multiple of the RGMII rates for 1G and 100M, but didn't check for 10M. Rather than use this with hard-coded speeds, check that the calculated divisor gives the required rate by multplying the transmit clock rate back up to the stmmac clock rate and checking that it agrees.

The maximum numbers of each Rx and Tx queues are defined by MTL_MAX_RX_QUEUES and MTL_MAX_TX_QUEUES respectively. There are some places where Rx and Tx are used in reverse. There is no issue when the Tx and Rx macros have the same value, but should correct usage of macros for maximum queue number to keep consistency and prevent unexpected mistakes.

2025-02-24net: dsa: rtl8366rb: Fix compilation problemLinus Walleij
When the kernel is compiled without LED framework support the rtl8366rb fails to build like this: rtl8366rb.o: in function `rtl8366rb_setup_led': rtl8366rb.c:953:(.text.unlikely.rtl8366rb_setup_led+0xe8): undefined reference to `led_init_default_state_get' rtl8366rb.c:980:(.text.unlikely.rtl8366rb_setup_led+0x240): undefined reference to `devm_led_classdev_register_ext' As this is constantly coming up in different randconfig builds, bite the bullet and create a separate file for the offending code, split out a header with all stuff needed both in the core driver and the leds code. Add a new bool Kconfig option for the LED compile target, such that it depends on LEDS_CLASS=y || LEDS_CLASS=RTL8366RB which make LED support always available when LEDS_CLASS is compiled into the kernel and enforce that if the LEDS_CLASS is a module, then the RTL8366RB driver needs to be a module as well so that modprobe can resolve the dependencies.

2025-02-24virtio-net: tweak for better TX performance in NAPI modeJason Wang
There are several issues existed in start_xmit(): - Transmitted packets need to be freed before sending a packet, this introduces delay and increases the average packets transmit time. This also increase the time that spent in holding the TX lock. - Notification is enabled after free_old_xmit_skbs() which will introduce unnecessary interrupts if TX notification happens on the same CPU that is doing the transmission now (actually, virtio-net driver are optimized for this case). So this patch tries to avoid those issues by not cleaning transmitted packets in start_xmit() when TX NAPI is enabled and disable notifications even more aggressively. Notification will be since the beginning of the start_xmit(). But we can't enable delayed notification after TX is stopped as we will lose the notifications. Instead, the delayed notification needs is enabled after the virtqueue is kicked for best performance. Performance numbers: 1) single queue 2 vcpus guest with pktgen_sample03_burst_single_flow.sh (burst 256) + testpmd (rxonly) on the host: - When pinning TX IRQ to pktgen VCPU: split virtqueue PPS were increased 55% from 6.89 Mpps to 10.7 Mpps and 32% TX interrupts were eliminated. Packed virtqueue PPS were increased 50% from 7.09 Mpps to 10.7 Mpps, 99% TX interrupts were eliminated. - When pinning TX IRQ to VCPU other than pktgen: split virtqueue PPS were increased 96% from 5.29 Mpps to 10.4 Mpps and 45% TX interrupts were eliminated; Packed virtqueue PPS were increased 78% from 6.12 Mpps to 10.9 Mpps and 99% TX interrupts were eliminated. 2) single queue 1 vcpu guest + vhost-net/TAP on the host: single session netperf from guest to host shows 82% improvement from 31Gb/s to 58Gb/s, %stddev were reduced from 34.5% to 1.9% and 88% of TX interrupts were eliminated.

2025-02-21net: mctp: Add MCTP USB transport driverJeremy Kerr
Add an implementation for DMTF DSP0283, which defines a MCTP-over-USB transport. As per that spec, we're restricted to full speed mode, requiring 512-byte transfers. Each MCTP-over-USB interface is a peer-to-peer link to a single MCTP endpoint, so no physical addressing is required (of course, that MCTP endpoint may then bridge to further MCTP endpoints). Consequently, interfaces will report with no lladdr data: # mctp link dev lo index 1 address 00:00:00:00:00:00 net 1 mtu 65536 up dev mctpusb0 index 6 address none net 1 mtu 68 up This is a simple initial implementation, with single rx & tx urbs, and no multi-packet tx transfers - although we do accept multi-packet rx from the device.

2025-02-21net: loopback: Avoid sending IP packets without an Ethernet headerIdo Schimmel
After commit 22600596b675 ("ipv4: give an IPv4 dev to blackhole_netdev") IPv4 neighbors can be constructed on the blackhole net device, but they are constructed with an output function (neigh_direct_output()) that simply calls dev_queue_xmit(). The latter will transmit packets via 'skb->dev' which might not be the blackhole net device if dst_dev_put() switched 'dst->dev' to the blackhole net device while another CPU was using the dst entry in ip_output(), but after it already initialized 'skb->dev' from 'dst->dev'. Specifically, the following can happen: CPU1 CPU2 udp_sendmsg(sk1) udp_sendmsg(sk2) udp_send_skb() [...] ip_output() skb->dev = skb_dst(skb)->dev dst_dev_put() dst->dev = blackhole_netdev ip_finish_output2() resolves neigh on dst->dev neigh_output() neigh_direct_output() dev_queue_xmit() This will result in IPv4 packets being sent without an Ethernet header via a valid net device: tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on enp9s0, link-type EN10MB (Ethernet), snapshot length 262144 bytes 22:07:02.329668 20:00:40:11:18:fb > 45:00:00:44:f4:94, ethertype Unknown (0x58c6), length 68: 0x0000: 8dda 74ca f1ae ca6c ca6c 0098 969c 0400 ..t....l.l...... 0x0010: 0000 4730 3f18 6800 0000 0000 0000 9971 ..G0?.h........q 0x0020: c4c9 9055 a157 0a70 9ead bf83 38ca ab38 ...U.W.p....8..8 0x0030: 8add ab96 e052 .....R Fix by making sure that neighbors are constructed on top of the blackhole net device with an output function that simply consumes the packets, in a similar fashion to dst_discard_out() and blackhole_netdev_xmit().

2025-02-21gve: Add RSS cache for non RSS device option scenarioZiwei Xiao
Not all the devices have the capability for the driver to query for the registered RSS configuration. The driver can discover this by checking the relevant device option during setup. If it cannot, the driver needs to store the RSS config cache and directly return such cache when queried by the ethtool. RSS config is inited when driver probes. Also the default RSS config will be adjusted when there is RX queue count change. At this point, only keys of GVE_RSS_KEY_SIZE and indirection tables of GVE_RSS_INDIR_SIZE are supported.

2025-02-21rtnetlink: Pack newlink() params into structXiao Liang
There are 4 net namespaces involved when creating links: - source netns - where the netlink socket resides, - target netns - where to put the device being created, - link netns - netns associated with the device (backend), - peer netns - netns of peer device. Currently, two nets are passed to newlink() callback - "src_net" parameter and "dev_net" (implicitly in net_device). They are set as follows, depending on netlink attributes in the request. +------------+-------------------+---------+---------+ | peer netns | IFLA_LINK_NETNSID | src_net | dev_net | +------------+-------------------+---------+---------+ | | absent | source | target | | absent +-------------------+---------+---------+ | | present | link | link | +------------+-------------------+---------+---------+ | | absent | peer | target | | present +-------------------+---------+---------+ | | present | peer | link | +------------+-------------------+---------+---------+ When IFLA_LINK_NETNSID is present, the device is created in link netns first and then moved to target netns. This has some side effects, including extra ifindex allocation, ifname validation and link events. These could be avoided if we create it in target netns from the beginning. On the other hand, the meaning of src_net parameter is ambiguous. It varies depending on how parameters are passed. It is the effective link (or peer netns) by design, but some drivers ignore it and use dev_net instead. To provide more netns context for drivers, this patch packs existing newlink() parameters, along with the source netns, link netns and peer netns, into a struct. The old "src_net" is renamed to "net" to avoid confusion with real source netns, and will be deprecated later. The use of src_net are converted to params->net trivially.

2025-02-21irqchip/qcom-pdc: Workaround hardware register bug on X1E80100Stephan Gerhold
On X1E80100, there is a hardware bug in the register logic of the IRQ_ENABLE_BANK register: While read accesses work on the normal address, all write accesses must be made to a shifted address. Without a workaround for this, the wrong interrupt gets enabled in the PDC and it is impossible to wakeup from deep suspend (CX collapse). This has not caused problems so far, because the deep suspend state was not enabled. A workaround is required now since work is ongoing to fix this. The PDC has multiple "DRV" regions, each one has a size of 0x10000 and provides the same set of registers for a particular client in the system. Linux is one the clients and uses DRV region 2 on X1E. Each "bank" inside the DRV region consists of 32 interrupt pins that can be enabled using the IRQ_ENABLE_BANK register: IRQ_ENABLE_BANK[bank] = base + IRQ_ENABLE_BANK + bank * sizeof(u32) On X1E, this works as intended for read access. However, write access to most banks is shifted by 2: IRQ_ENABLE_BANK_X1E[0] = IRQ_ENABLE_BANK[-2] IRQ_ENABLE_BANK_X1E[1] = IRQ_ENABLE_BANK[-1] IRQ_ENABLE_BANK_X1E[2] = IRQ_ENABLE_BANK[0] = IRQ_ENABLE_BANK[2 - 2] IRQ_ENABLE_BANK_X1E[3] = IRQ_ENABLE_BANK[1] = IRQ_ENABLE_BANK[3 - 2] IRQ_ENABLE_BANK_X1E[4] = IRQ_ENABLE_BANK[2] = IRQ_ENABLE_BANK[4 - 2] IRQ_ENABLE_BANK_X1E[5] = IRQ_ENABLE_BANK[5] (this one works as intended) The negative indexes underflow to banks of the previous DRV/client region: IRQ_ENABLE_BANK_X1E[drv 2][bank 0] = IRQ_ENABLE_BANK[drv 2][bank -2] = IRQ_ENABLE_BANK[drv 1][bank 5-2] = IRQ_ENABLE_BANK[drv 1][bank 3] = IRQ_ENABLE_BANK[drv 1][bank 0 + 3] IRQ_ENABLE_BANK_X1E[drv 2][bank 1] = IRQ_ENABLE_BANK[drv 2][bank -1] = IRQ_ENABLE_BANK[drv 1][bank 5-1] = IRQ_ENABLE_BANK[drv 1][bank 4] = IRQ_ENABLE_BANK[drv 1][bank 1 + 3] Introduce a workaround for the bug by matching the qcom,x1e80100-pdc compatible and apply the offsets as shown above: - Bank 0...1: previous DRV region, bank += 3 - Bank 1...4: our DRV region, bank -= 2 - Bank 5: our DRV region, no fixup required The PDC node in the device tree only describes the DRV region for the Linux client, but the workaround also requires to map parts of the previous DRV region to issue writes there. To maintain compatibility with old device trees, obtain the base address of the preceeding region by applying the -0x10000 offset. Note that this is also more correct from a conceptual point of view: It does not really make use of the other region; it just issues shifted writes that end up in the registers of the Linux associated DRV region 2.

Commit bb9850704c04 ("scsi: ufs: core: Honor runtime/system PM levels if set by host controller drivers") introduced the check for setting default PM levels only if the levels are uninitialized by the host controller drivers. But it missed the fact that the levels could be initialized to 0 (UFS_PM_LVL_0) on purpose by the controller drivers. Even though none of the drivers are doing so now, the logic should be fixed irrespectively. So set the default levels unconditionally before calling ufshcd_hba_init() API which initializes the controller drivers. It ensures that the controller drivers could override the default levels if required.

2025-02-20net/mlx5e: Separate extended link modes request from link modes type selectionShahar Shitrit
The function ext_requested() serves two distinct purposes: it checks if extended link modes were requested, and it selects whether to use extended or legacy link modes. This change separates these two purposes. Now, ext_link_mode_requested() is used directly for checking if extended link modes are requested, while the selection of extended modes is handled independently based on the autonegotiation status. By making this distinction, the logic for determining whether to select extended or legacy link modes is clearer.

2025-02-20net/mlx5e: Change eth_proto parameter namingShahar Shitrit
eth_proto_cap parameter represents the supported link modes, while eth_proto_admin refers to the configured ones. The function get_advertising() retrieves the configured link modes, thus we update its parameter name to eth_proto_admin.

2025-02-20net/mlx5e: Refactor ptys2ethtool_adver_link()Shahar Shitrit
The function ptys2ethtool_adver_link() contains duplicated code that is found in mlx5e_ethtool_get_speed_arr(). To eliminate this redundancy, we update mlx5e_ethtool_get_speed_arr() to select the appropriate table based on the ext argument passed by the caller, rather than querying the supported mode locally. This allows us to replace the current logic in ptys2ethtool_adver_link() with a call to mlx5e_ethtool_get_speed_arr(). This adjustment aligns with the ptys2ethtool_supported_link() function and prepares for an upcoming patch that reduces code duplication.
