2026-07-30net: mctp: usb: Use packet-length max for maximum packet-size checkJeremy Kerr2-2/+3
The max packet size is smaller than the max transfer size, as we only have a u8 length field in the transport header. Add a define for the maximum representable length, and use that for our check. Use this for the MTU maximum calculation too.

2026-07-30ksmbd: use memcmp() to compare ClientGUIDsNamjae Jeon1-2/+2
ClientGUID is a fixed-size binary value and can contain embedded NUL bytes. strncmp() stops comparing at the first NUL byte, so different ClientGUID values can incorrectly be treated as equal. Use memcmp() in SMB3 multichannel session binding and FSCTL_VALIDATE_NEGOTIATE_INFO to compare all SMB2_CLIENT_GUID_SIZE bytes.

2026-07-30ksmbd: reject repeated SMB2 NEGOTIATE requestsNamjae Jeon3-15/+37
Unauthenticated client can send multiple successful SMB2 NEGOTIATE requests on one connection before SESSION_SETUP. While the connection is in KSMBD_SESS_NEED_SETUP, smb2_handle_negotiate() accepts another SMB3.1.1 NEGOTIATE and overwrites conn->preauth_info with a new allocation. Only the final allocation is freed when the connection is released, leaking one object for every additional successful request. A repeated SMB2 NEGOTIATE after a dialect has been selected is a protocol violation. MS-SMB2 section 3.3.5.4 requires the server to disconnect without replying in this case. Set the connection exiting when rejecting the request, in addition to suppressing the response. Reject SMB2 NEGOTIATE unless the connection is new or is waiting for the SMB2 NEGOTIATE that follows an SMB1 multi-protocol negotiate. Serialize both SMB1 and SMB2 negotiation paths under conn->srv_mutex, since they update connection-wide dialect and negotiation state. Move the locking contract to ksmbd_smb_negotiate_common(), where the state and dialect are selected, and add ksmbd_conn_new() for consistent state access.

2026-07-30ksmbd: fix use-after-free in __close_file_table_ids()Namjae Jeon1-0/+2
A ksmbd_file can remain alive after logical close while another session holds a temporary reference obtained through ksmbd_lookup_fd_inode(). ksmbd_close_fd() currently marks the file closed and drops the idr-owned reference, but leaves the pointer published in the closing session's idr until the final reference is dropped. If the foreign holder performs the final ksmbd_fd_put(), __put_fd_final() supplies the foreign session's file table to __ksmbd_close_fd(). The object is then freed without being removed from its owner's idr, and the owner session later dereferences the stale pointer during file-table teardown. Remove the volatile id from the owner's idr while ksmbd_close_fd() still holds that table's lock, and clear volatile_id before dropping the idr-owned reference. A later foreign final put then only performs physical destruction and cannot remove the object from the wrong table.

2026-07-30pds_core: cancel pending PCI reset work on AER recoveryNikhil P. Rao1-0/+4
pdsc_check_pci_health() queues pci_reset_work when it sees a broken PCI connection, and nothing cancels it. When the PCI core starts AER recovery, pdsc_pci_error_detected() runs pdsc_reset_prepare() and recovers the device, but a pci_reset_work queued just before is left pending. If it runs after recovery released the device lock, it resets a device the driver now considers healthy, bouncing the link for no reason. Cancel pci_reset_work in pdsc_pci_error_detected() after pdsc_reset_prepare(), which has already stopped the health thread so it cannot requeue the work. cancel_work_sync() is safe under the device lock here because pdsc_pci_reset_thread() uses pci_try_reset_function(), which returns instead of blocking on the lock. Only PFs initialize pci_reset_work, so guard the cancel with !is_virtfn.

2026-07-30pds_core: keep the health thread stopped during resetNikhil P. Rao2-2/+9
Commit d9407ff11809 ("pds_core: Prevent health thread from running during reset/remove") stops the health thread with cancel_work_sync() before a reset, but a devcmd timeout during pdsc_fw_down() re-queues health_work, so pdsc_health_thread() runs again mid-reset and double allocates the core DMA queues via pdsc_fw_up(). Only the reset path is affected: on remove PDSC_S_STOPPING_DRIVER gates the health thread and the workqueue is destroyed. Use disable_work_sync() to cancel health_work and block further queue_work() on it, and enable_work() in pdsc_restart_health_thread() to re-allow it after the reset. disable_work_sync() keeps a disable depth, so every disable must be matched by one enable. pdsc_reset_prepare() stops the health thread and pdsc_reset_done() restarts it. On the AER path pdsc_pci_error_detected() calls pdsc_reset_prepare(), then pdsc_pci_error_resume() re-inits via pci_reset_function_locked() (pds_core has no .slot_reset handler), which runs the pair again - stopping the thread twice but restarting it once. Gate the disable and enable on a health_stopped flag so each fires at most once per stopped/running transition.

2026-07-30net/mlx5e: TC, Check if flow is PEER before acquiring devcom lockShay Drory2-1/+4
In case __mlx5e_add_fdb_flow() fails in lower levels, the flow is deleted via mlx5e_tc_del_flow(), and mlx5e_tc_del_flow() is acquiring ESW devcom lock without condition. In addition, in case of peer_flow, __mlx5e_add_fdb_flow() is called while holding ESW devcom comp lock. This results in an AA deadlock.

2026-07-30enic: fix tx_hang_reset use-after-free on device removalSatish Kharat1-2/+3
enic_remove() cancels the reset and change_mtu_work items but does not cancel tx_hang_reset. A TX timeout that fires while the device is being removed can schedule enic_tx_hang_reset() so that it runs after free_netdev(), resulting in a use-after-free. cancel_work_sync() alone is not sufficient here: the still-live watchdog and notify paths can re-schedule these work items in the window between the cancel and unregister_netdev(). Use disable_work_sync(), which cancels the work and blocks any subsequent schedule_work() from requeuing it, and apply it to the reset and change_mtu_work items as well so the same requeue race is closed for all teardown work.

2026-07-30net/packet: reset the MAC header on the packet-socket transmit pathDoruk Tan Ozturk1-3/+4
packet_parse_headers() resets the MAC header only for a SOCK_RAW frame whose socket did not bind a protocol. A protocol-bound SOCK_RAW socket, any SOCK_DGRAM frame, and the legacy SOCK_PACKET path therefore leave skb->mac_header unset here. For frames sent via __dev_queue_xmit() this is harmless: it resets the MAC header unconditionally. But the packet-socket PACKET_QDISC_BYPASS path uses dev_direct_xmit(), which does not, so the frame reaches ndo_start_xmit() with the MAC header unset. A driver that reads eth_hdr(skb) on transmit then dereferences skb->head + (u16)~0, an out-of-bounds access ~64 KiB past the head -- the same class fixed for one consumer in commit f5089008f90c ("macsec: do not read an unset MAC header in macsec_encrypt()"). packet_parse_headers() runs only on the transmit path, where skb->data points at the start of the L2 header for every packet-socket type regardless of its length: SOCK_RAW and SOCK_PACKET carry a user-supplied header and SOCK_DGRAM has one built by dev_hard_header(). Reset the MAC header unconditionally, mirroring __dev_queue_xmit(), so the frame is anchored on the bypass path too.

2026-07-30bonding: alb: re-check primary_is_promisc under RTNL in bond_alb_monitorXiang Mei (Microsoft)1-4/+6
bond_alb_monitor() reads primary_is_promisc under RCU, then drops RCU and takes RTNL via rtnl_trylock() before undoing the promiscuity it set on the active slave. In that window the active slave can change under RTNL (RTM_DELLINK -> __bond_release_one() -> bond_alb_handle_active_change()), which already drops the promiscuity and clears primary_is_promisc. The monitor still acts on the stale decision: if the slave was removed with no failover, curr_active_slave is now NULL and the deref faults; if it failed over, the stale dev_set_promiscuity(-1) underflows the new slave's promiscuity counter and pins it in IFF_PROMISC.

2026-07-30Revert "net: thunderbolt: Enable end-to-end flow control also in transmit"Fan Ye1-6/+7
This reverts commit a8065af3346ebd7c76ebc113451fb3ba94cf7769. Per the USB4 spec, a Transmit Descriptor Ring with E2E flow control disabled does not require any credits to be available before the Host Interface Adapter Layer transmits a tunneled packet from it. Once E2E is enabled on that ring the controller must first obtain end-to-end credits. The ASMedia ASM4242 USB4 host router (PCI 1b21:2425) never delivers those credits. The controller does accept the configuration: reading the ring OPTIONS register back right after tb_ring_start() returns exactly what was written, including RING_FLAG_E2E_FLOW_CONTROL (bit 28) and the E2E HopID field. No credit ever arrives though, so the Tx ring's hardware consumer index never advances and the link carries no traffic at all. Measured on two hosts connected point to point, onboard ASM4242 on MSI X870E and X870, v6.17, stock drivers/net/thunderbolt/main.c with only this revert applied on top: before: 100% packet loss to the peer; thunderbolt0 is up and the XDomain handshake completes ("new host found"), but iperf3 fails with "No route to host" once the neighbour entry expires after: 0% packet loss, 0.28 ms RTT; iperf3 4.21 Gb/s one way and 5.17 Gb/s the other (5 runs each, stddev <= 0.02), 1 retransmit in 10 s An instrumented build additionally showed a frozen-Tx-consumer watchdog firing ~30k times in a 10 s window before this change. Rx-side E2E is not touched by this revert, so peers that do return credits keep receive-side flow control. ASMedia does not look like an isolated case. The out-of-tree thunderbolt-ibverbs project disables native E2E on AMD NHI by default, noting that "Strix Halo has reproduced TX completion wedges with multiple native E2E rings active" -- the same failure mode, on a different vendor. Since the driver has no way to tell in advance which host router returns the credits, going back to the previous behaviour looks safer than adding a quirk per affected part; Tx-side E2E can be reintroduced as an opt-in for controllers that are known to implement the credit return. Note that the reverted commit was not fixing a reported problem, it was derived from the spec wording alone, so this revert is not expected to regress a known workload.

2026-07-30Merge branch 'net-nexthop-per-nexthop-udp-dst-port-for-fdb-vxlan-nexthops'Jakub Kicinski6-5/+152
Jack Ma says: ==================== net: nexthop: per-nexthop UDP dst port for fdb (VXLAN) nexthops FDB nexthops let a VXLAN fdb entry point at a group of remote VTEPs, with the kernel flow-hashing across the group (commit 1274e1cc4226 ("vxlan: ecmp support for mac fdb entries")). Each leg carries its own remote IP, but the UDP destination port is always taken from the VXLAN device (vxlan->cfg.dst_port) and cannot be set per leg. This series adds an optional per-nexthop UDP destination port for fdb nexthops, so a group's legs can share a remote IP and differ only in UDP port. Motivation The deployment runs an overlay in which each tenant's traffic is terminated by a "forwarder": a pod that hosts the VXLAN VTEP, decapsulates the tenant's overlay, and relays it to and from that tenant's workload. Forwarders for many different tenants are packed onto the same receiver node behind one mesh-routable underlay IP, and are demultiplexed purely by UDP destination port. The host does a stateless outer-UDP demux by port; it never terminates the tunnel: receiver node -- one mesh-routable underlay IP (NodeIP_A) +----------------------------------------------------+ | host netns: stateless outer-UDP demux by dst port | | (host does NOT terminate the tunnel) | | | | dst :40000 dst :40001 dst :40002 | | | | | | | +-----v----+ +-----v----+ +-----v----+ | | | pod0 ns | | pod1 ns | | pod2 ns | | | | vxlan | | vxlan | | vxlan | | | | VTEP | | VTEP | | VTEP | | | | decap | | decap | | decap | | | +----------+ +----------+ +----------+ | +----------------------------------------------------+ (up to ~10 forwarder pods packed per node) The packed pods are unrelated: each belongs to a different tenant on its own VXLAN VNI, so the per-pod UDP port is node-level demux, not an HA construct. The host, which only demuxes outer UDP, never has to reason about tenancy. A single forwarder is made highly available by running replicas. The replicas of one forwarder share a single anycast overlay identity: one inner MAC and IP. Clients address that one identity, and a sender spreads flows across the live replicas with an fdb nexthop group. Failover is transparent: a dead replica is just dropped from the group, with no client re-resolution or route change. The single identity is deliberate; the endpoint is consumed one layer up as a single stable address, so giving each replica its own address would push multi-address handling and health-checking up into that consumer. Anti-affinity keeps the two replicas of one HA set on different nodes, so a group's legs land on distinct node IPs. But each leg is still reachable only at (node IP, that pod's UDP port), so within one group the legs differ in IP *and* port. A group can already carry a distinct IP per leg, but it takes the UDP port from the device (a single value), so it cannot send each leg to its own port. That is the gap this series closes. Zooming into one forwarder pod, there is nothing for the host to load-balance: the tunnel terminates on a vxlan device inside the pod's own netns, and the pod reaches its tenant through a separate NIC: one forwarder pod -- its own netns, tenant VNI X +-------------------------------------------------+ | | | on/off-ramp NIC <--- customer data plane | | | on-ramp (ingress) / off-ramp (egress) | | | inner packet | | vxlan (VTEP) encap / decap for VNI X, | | | listens on this pod's UDP port | | | outer VXLAN UDP | | eth0 (underlay) NodeIP:port | | | to peer VTEPs over the | | v mesh underlay | | | +-------------------------------------------------+ Existing mechanisms do not fit this shape: - L3 multipath in the overlay needs each leg to be a distinct routable nexthop with its own address. Since an HA set is a single anycast address by design, there are no distinct per-leg addresses to route over; the fdb nexthop group bridging to that shared MAC is what load-balances. - Host-side fan-out (XDP / TC / SO_REUSEPORT) assumes a shared host datapath that is not there. SO_REUSEPORT balances sockets within one netns, but the receivers are in different netns (in fact different tenants). An XDP/TC fan-out would require the host to terminate the tunnel and re-dispatch inner traffic across netns and VNI boundaries, i.e. become a VTEP, which puts the host into the tenant datapath and largely duplicates what an fdb nexthop group already does. - Demuxing on VNI instead of port (one shared 4789 socket, multiple vxlan devices differing only in VNI, moved into each pod's netns) works when the co-located pods have different VNIs. It does not help two same-VNI HA sets on one node: their outer headers are identical, so the host would again have to terminate the tunnel to tell them apart. It also costs packing density: with one shared underlay IP, VNI demux allows at most one VTEP per (VNI, node), so N same-VNI HA sets of two replicas need 2N nodes, whereas a per-pod port fits them on two nodes with anti-affinity preserved. This series adds the attribute: - Patch 1 adds a netlink attribute NHA_DST_PORT (__be16, mirroring NDA_PORT), stored in struct nh_info and echoed back on dump. It is only accepted together with NHA_FDB and NHA_GATEWAY. Control-plane only; datapath behaviour is unchanged. - Patch 2 wires it into the VXLAN datapath: vxlan_fdb_nh_path_select() sets rdst->remote_port to the selected leg's port. vxlan_xmit_one() already prefers rdst->remote_port when non-zero and otherwise falls back to the device port, so nexthops without a port are unaffected (backward compatible). - Patch 3 extends the fdb nexthop selftests. On the uAPI: this does not add a new datapath concept. A single fdb entry already carries a per-destination UDP port (NDA_PORT), and vxlan_xmit_one() already prefers rdst->remote_port when set. NHA_DST_PORT is the nexthop analog of that existing attribute: control-plane only, no datapath change, and backward compatible (a leg with no port falls back to the device port as today). It sits at the nexthop level rather than under NHA_ENCAP because fdb nexthops do not use the NHA_ENCAP / LWT infrastructure. Example: ip nexthop add id 1 via 192.0.2.10 fdb dst_port 4789 ip nexthop add id 2 via 192.0.2.10 fdb dst_port 5789 ip nexthop add id 10 group 1/2 fdb bridge fdb add 00:11:22:33:44:55 dev vxlan0 nhid 10 Both legs share gateway 192.0.2.10 and differ only in UDP port; the kernel hashes flows across them. ==================== Link: https://patch.msgid.link/20260724-b4-vxlan-fdb-port-v5-0-cd1c6aeee058@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2026-07-30selftests: net: add coverage for fdb nexthop dst_portJack Ma2-2/+121
Add coverage for the new per-nexthop VXLAN destination port (NHA_DST_PORT). In fib_nexthops.sh, new ipv4_fdb_port_fcnal() and ipv6_fdb_port_fcnal() tests check that a dst_port is accepted on an fdb nexthop that has a gateway and echoed back on dump, that it is rejected without a gateway and rejected when zero, that a group may hold legs that differ only in UDP port, and that a portless fdb nexthop omits the attribute. The tests SKIP when iproute2 lacks the "dst_port" keyword. In test_vxlan_nh.sh, basic_tx_common() gains a second fdb nexthop group whose nexthop carries a destination port that differs from the VXLAN device default, plus a flower filter keyed on that port, to confirm the per-nexthop port is used on the wire. The test now requires an iproute2 with dst_port support.

2026-07-30vxlan: honor per-nexthop fdb destination portJack Ma2-2/+7
When an fdb entry points at a nexthop group, vxlan_fdb_nh_path_select() resolves the selected leg's remote IP but leaves the UDP destination port at the device default (vxlan->cfg.dst_port). Extend nexthop_path_fdb_result() to also return the selected nexthop's NHA_DST_PORT (0 when unset) and have vxlan_fdb_nh_path_select() store it in rdst->remote_port. vxlan_xmit_one() already prefers rdst->remote_port when non-zero and falls back to the device port otherwise, so nexthops without a port are unaffected. This lets one fdb nexthop group load-balance a flow across legs that share an underlay IP but differ in UDP destination port.

2026-07-30net: nexthop: add NHA_DST_PORT for fdb nexthopsJack Ma3-1/+24
Commit 1274e1cc4226 ("vxlan: ecmp support for mac fdb entries") lets a single inner MAC be reached through a group of remote VTEPs, with the kernel flow-hashing across the group members. Each member carries its own remote IP, but the UDP destination port is always taken from the VXLAN device (vxlan->cfg.dst_port) and cannot be set per member. Some deployments pack several receivers behind one underlay IP and tell them apart by UDP port, so they need a per-nexthop destination port to spread flows across (IP, port) tuples rather than IP alone. Add a netlink attribute NHA_DST_PORT (__be16, mirroring NDA_PORT) that carries an optional UDP destination port on an fdb nexthop. It is only accepted together with NHA_FDB and NHA_GATEWAY; it is stored in struct nh_info and echoed back on dump. The attribute is named generically rather than fdb-specific so it can be reused should another nexthop type ever need a destination port. This patch is control-plane plumbing only; the VXLAN datapath is wired up in a follow-up patch, so behaviour is unchanged for now.

If either tplg_ops->dai_config or widget_kcontrol_setup fail during widget setup we would double decrement the use_count of the widget because the sof_widget_free_unlocked() would be called twice, similarly the core_put would be invoked twice as well. Since the use_count and core_put() is handled within the widget_free function we need to return without falling through the pipe_widget_free label.

2026-07-30net: hns3: fix speed configuration residue after driver reloadJijie Shao1-5/+1
After setting a 100G optical port to 40G via ethtool and reloading the driver, the port remains at 40G instead of reverting to the firmware default speed of 100G. The commit referenced in Fixes: added two overwrites in hclge_init_ae_dev() for non-copper media, so that optical ports connected to forced-mode remotes inherit the firmware-preset autoneg and speed instead of the hardcoded defaults: req_autoneg = mac.autoneg req_speed = mac.speed (when autoneg disabled) The autoneg overwrite keeps existing behavior: hclge_set_autoneg_speed_dup() already uses mac.autoneg (not req_autoneg) since it was introduced, so autoneg inheritance from firmware was already in place. This part is kept. The speed overwrite, however, introduces the residue: mac.speed reflects whatever was last programmed into the MAC, and after unload firmware does not restore the MAC speed to the flash default. So if the user changed speed via ethtool in a prior load, mac.speed still carries that value on reload and req_speed inherits it. Fix by dropping the req_speed overwrite only. req_speed keeps the firmware default value set in hclge_configure() (cfg.default_speed), so a reload reverts the speed to default, matching the expectation that a driver reload resets link configuration. Trade-off: on optical ports whose firmware default speed does not match a forced-mode remote, reload now drops the link and the user must re-apply ethtool configuration. This is acceptable: a driver reload is expected to reset link configuration, not to inherit runtime state from before unload. The autoneg inheritance is left in place as established behavior; changing it is out of scope for this patch and would itself be a user-perceivable behavior change.

2026-07-31power: supply: charger-manager: register regulators before exposing sysfsFan Wu1-15/+39
charger_manager_remove() and the err_reg_extcon probe error path free each charger regulator with regulator_put() before tearing down the power_supply sysfs entries (power_supply_unregister()). charger_manager_remove() also calls try_charger_enable(cm, false) after the regulator_put() loop. A concurrent write to a charger's externally_control sysfs attribute that lands between regulator_put() and power_supply_unregister() can run charger_externally_control_store() and call try_charger_enable(), which, when charging is enabled, dereferences the already-freed consumer handle. When charging is enabled, try_charger_enable(cm, false) in .remove() also dereferences the freed handles directly. Both leave use-after-free windows. Symmetrically, probe registers the sysfs entries (power_supply_register) before acquiring the regulators (regulator_get, inside charger_manager_register_extcon), so userspace can reach externally_control before the regulators are available. Split charger_manager_register_extcon() on the sync/async boundary: charger_manager_get_regulators() (regulator_get only, no async producer) now runs before power_supply_register() so sysfs is not live before regulators are available, and charger_manager_register_extcon() keeps only the extcon notifier/work setup, still after power_supply_register() so a power_supply_register() failure cannot reach extcon setup. This keeps the sysfs setup/teardown ordering symmetric without introducing an asynchronous producer on the earlier probe-error path. Move power_supply_unregister() and try_charger_enable(cm, false) ahead of the regulator_put() loop on both teardown paths, and adjust err_reg_extcon (power_supply_unregister() then fall through err_regulator for regulator_put(); get_regulators self-rolls back on its own failure). This does not address the separate extcon-notifier-driven deref of the same handles, which needs its own synchronization design. Found by an in-house static analysis tool.
