2025-11-26net: atlantic: fix fragment overflow handling in RX pathJiefeng Zhang
The atlantic driver can receive packets with more than MAX_SKB_FRAGS (17) fragments when handling large multi-descriptor packets. This causes an out-of-bounds write in skb_add_rx_frag_netmem() leading to kernel panic. The issue occurs because the driver doesn't check the total number of fragments before calling skb_add_rx_frag(). When a packet requires more than MAX_SKB_FRAGS fragments, the fragment index exceeds the array bounds. Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE, then all fragments are accounted for. And reusing the existing check to prevent the overflow earlier in the code path. This crash occurred in production with an Aquantia AQC113 10G NIC.

2025-11-26virtio-net: avoid unnecessary checksum calculation on guest RXJon Kohler
Commit a2fb4bc4e2a6 ("net: implement virtio helpers to handle UDP GSO tunneling.") inadvertently altered checksum offload behavior for guests not using UDP GSO tunneling. Before, tun_put_user called tun_vnet_hdr_from_skb, which passed has_data_valid = true to virtio_net_hdr_from_skb. After, tun_put_user began calling tun_vnet_hdr_tnl_from_skb instead, which passes has_data_valid = false into both call sites. This caused virtio hdr flags to not include VIRTIO_NET_HDR_F_DATA_VALID for SKBs where skb->ip_summed == CHECKSUM_UNNECESSARY. As a result, guests are forced to recalculate checksums unnecessarily. Restore the previous behavior by ensuring has_data_valid = true is passed in the !tnl_gso_type case, but only from tun side, as virtio_net_hdr_tnl_from_skb() is used also by the virtio_net driver, which in turn must not use VIRTIO_NET_HDR_F_DATA_VALID on tx. cc: stable@vger.kernel.org Fixes: a2fb4bc4e2a6 ("net: implement virtio helpers to handle UDP GSO tunneling.")

2025-11-26net: dsa: sja1105: fix SGMII linking at 10M or 100M but not passing trafficVladimir Oltean
When using the SGMII PCS as a fixed-link chip-to-chip connection, it is easy to miss the fact that traffic passes only at 1G, since that's what any normal such connection would use. When using the SGMII PCS connected towards an on-board PHY or an SFP module, it is immediately noticeable that when the link resolves to a speed other than 1G, traffic from the MAC fails to pass: TX counters increase, but nothing gets decoded by the other end, and no local RX counters increase either. Artificially lowering a fixed-link rate to speed = <100> makes us able to see the same issue as in the case of having an SGMII PHY. Some debugging shows that the XPCS configuration is A-OK, but that the MAC Configuration Table entry for the port has the SPEED bits still set to 1000Mbps, due to a special condition in the driver. Deleting that condition, and letting the resolved link speed be programmed directly into the MAC speed field, results in a functional link at all 3 speeds. This piece of evidence, based on testing on both generations with SGMII support (SJA1105S and SJA1110A) directly contradicts the statement from the blamed commit that "the MAC is fixed at 1 Gbps and we need to configure the PCS only (if even that)". Worse, that statement is not backed by any documentation, and no one from NXP knows what it might refer to. I am unable to recall sufficient context regarding my testing from March 2020 to understand what led me to draw such a braindead and factually incorrect conclusion. Yet, there is nothing of value regarding forcing the MAC speed, either for SGMII or 2500Base-X (introduced at a later stage), so remove all such logic.

2025-11-26net: dpaa: fman_memac: complete phylink support with 2500base-xVladimir Oltean
The DPAA phylink conversion in the following commits partially developed code for handling the 2500base-x host interface mode (called "2.5G SGMII" in LS1043A/LS1046A reference manuals). - 0fc83bd79589 ("net: fman: memac: Add serdes support") - 5d93cfcf7360 ("net: dpaa: Convert to phylink") In principle, having phy-interface-mode = "2500base-x" and a pcsphy-handle (unnamed or with pcs-handle-names = "sgmii") in the MAC device tree node results in PHY_INTERFACE_MODE_2500BASEX being set in phylink_config :: supported_interfaces, but this isn't sufficient. Because memac_select_pcs() returns no PCS for PHY_INTERFACE_MODE_2500BASEX, the Lynx PCS code never engages. There's a chance the PCS driver doesn't have any configuration to change for 2500base-x fixed-link (based on bootloader pre-initialization), but there's an even higher chance that this is not the case, and the PCS remains misconfigured. More importantly, memac_if_mode() does not handle PHY_INTERFACE_MODE_2500BASEX, and it should be telling the mEMAC to configure itself in GMII mode (which is upclocked by the PCS). Currently it prints a WARN_ON() and returns zero, aka IF_MODE_10G (incorrect). The additional case statement in memac_prepare() for calling phy_set_mode_ext() does not make any difference, because there is no generic PHY driver for the Lynx 10G SerDes from LS1043A/LS1046A. But we add it nonetheless, for consistency. Regarding the question "did 2500base-x ever work with the FMan mEMAC mainline code prior to the phylink conversion?" - the answer is more nuanced. For context, the previous phylib-based implementation was unable to describe the fixed-link speed as 2500, because the software PHY implementation is limited to 1G. However, improperly describing the link as an sgmii fixed-link with speed = <1000> would have resulted in a functional 2.5G speed, because there is no other difference than the SerDes lane clock net frequency (3.125 GHz for 2500base-x) - all the other higher-level settings are the same, and the SerDes lane frequency is currently handled by the RCW. But this hack cannot be extended towards a phylib PHY such as Aquantia operating in OCSGMII, because the latter requires phy-mode = "2500base-x", which the mEMAC driver did not support prior to the phylink conversion. So I do not really consider this a regression, just completing support for a missing feature. The FMan mEMAC driver sets phylink's "default_an_inband" property to true, making it as if the device tree node had the managed = "in-band-status" property anyway. This default made sense for SGMII, where it was added to avoid regressions, but for 2500base-x we learned only recently how to enable in-band autoneg: https://lore.kernel.org/netdev/20251122113433.141930-1-vladimir.oltean@nxp.com/ so the driver needs to opt out of this default in-band enabled behaviour, and only enable in-band based on the device tree property.

2025-11-26net: phy: dp83867: implement configurability for SGMII in-band auto-negotiationVladimir Oltean
Implement the inband_caps() and config_inband() PHY driver methods, to allow working with PCS devices that do not support or want in-band to be used. There is a complication due to existing logic from commit c76acfb7e19d ("net: phy: dp83867: retrigger SGMII AN when link change") which might re-enable what dp83867_config_inband() has disabled. So we need to modify dp83867_link_change_notify() to use phy_modify_changed() when temporarily disabling in-band autoneg. If the return code is 0, it means the original in-band was disabled and we need to keep it disabled. If the return code is 1, the original was enabled and we need to re-enable it. If negative, there was an error, which was silent before, and remains silent now. dp83867_config_inband() and dp83867_link_change_notify() are serialized by the phydev->lock.

2025-11-26tools: ynl: add YNL test frameworkHangbin Liu
Add a test framework for YAML Netlink (YNL) tools, covering both CLI and ethtool functionality. The framework includes: 1) cli: family listing, netdev, ethtool, rt-* families, and nlctrl operations 2) ethtool: device info, statistics, ring/coalesce/pause parameters, and feature gettings The current YNL syntax is a bit obscure, and end users may not always know how to use it. This test framework provides usage examples and also serves as a regression test to catch potential breakages caused by future changes.

2025-11-26of: Add wrappers to match root node with OF device ID tablesKrzysztof Kozlowski
Several drivers duplicate same code for getting reference to the root node, matching it against 'struct of_device_id' table and getting out the match data from the table entry. There is a of_machine_compatible_match() wrapper but it takes array of strings, which is not suitable for many drivers since they want the driver data associated with each compatible. Add two wrappers, similar to existing of_device_get_match_data(): 1. of_machine_device_match() doing only matching against 'struct of_device_id' and returning bool. 2. of_machine_get_match_data() doing the matching and returning associated driver data for found compatible.

Breno Leitao says: ==================== net: intel: migrate to .get_rx_ring_count() ethtool callback This series migrates Intel network drivers to use the new .get_rx_ring_count() ethtool callback introduced in commit 84eaf4359c36 ("net: ethtool: add get_rx_ring_count callback to optimize RX ring queries"). The new callback simplifies the .get_rxnfc() implementation by removing ETHTOOL_GRXRINGS handling and moving it to a dedicated callback. This provides a cleaner separation of concerns and aligns these drivers with the modern ethtool API.
