2025-07-03Merge branch 'fix-irq-vectors'Paolo Abeni
Jiawen Wu says: ==================== Fix IRQ vectors The interrupt vector order was adjusted by [1]commit 937d46ecc5f9 ("net: wangxun: add ethtool_ops for channel number") in Linux-6.8. Because at that time, the MISC interrupt acts as the parent interrupt in the GPIO IRQ chip. When the number of Rx/Tx ring changes, the last MISC interrupt must be reallocated. Then the GPIO interrupt controller would be corrupted. So the initial plan was to adjust the sequence of the interrupt vectors, let MISC interrupt to be the first one and do not free it. Later, irq_domain was introduced in [2]commit aefd013624a1 ("net: txgbe: use irq_domain for interrupt controller") to avoid this problem. However, the vector sequence adjustment was not reverted. So there is still one problem that has been left unresolved. Due to hardware limitations of NGBE, queue IRQs can only be requested on vector 0 to 7. When the number of queues is set to the maximum 8, the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by MISC interrupt, and althrough the vector 8 is used by queue interrupt, it is unable to receive packets. This will cause some packets to be dropped when RSS is enabled and they are assigned to queue 8. This patch set fix the above problems.

2025-07-03net: ngbe: specify IRQ vector when the number of VFs is 7Jiawen Wu
For NGBE devices, the queue number is limited to be 1 when SRIOV is enabled. In this case, IRQ vector[0] is used for MISC and vector[1] is used for queue, based on the previous patches. But for the hardware design, the IRQ vector[1] must be allocated for use by the VF[6] when the number of VFs is 7. So the IRQ vector[0] should be shared for PF MISC and QUEUE interrupts. +-----------+----------------------+ | Vector | Assigned To | +-----------+----------------------+ | Vector 0 | PF MISC and QUEUE | | Vector 1 | VF 6 | | Vector 2 | VF 5 | | Vector 3 | VF 4 | | Vector 4 | VF 3 | | Vector 5 | VF 2 | | Vector 6 | VF 1 | | Vector 7 | VF 0 | +-----------+----------------------+ Minimize code modifications, only adjust the IRQ vector number for this case.

Laurent Vivier says: ==================== virtio: Fixes for TX ring sizing and resize error reporting This patch series contains two fixes and a cleanup for the virtio subsystem. The first patch fixes an error reporting bug in virtio_ring's virtqueue_resize() function. Previously, errors from internal resize helpers could be masked if the subsequent re-enabling of the virtqueue succeeded. This patch restores the correct error propagation, ensuring that callers of virtqueue_resize() are properly informed of underlying resize failures. The second patch does a cleanup of the use of '2+MAX_SKB_FRAGS' The third patch addresses a reliability issue in virtio_net where the TX ring size could be configured too small, potentially leading to persistently stopped queues and degraded performance. It enforces a minimum TX ring size to ensure there's always enough space for at least one maximally-fragmented packet plus an additional slot. ==================== Link: https://patch.msgid.link/20250521092236.661410-1-lvivier@redhat.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2025-07-03virtio_net: Enforce minimum TX ring size for reliabilityLaurent Vivier
The `tx_may_stop()` logic stops TX queues if free descriptors (`sq->vq->num_free`) fall below the threshold of (`MAX_SKB_FRAGS` + 2). If the total ring size (`ring_num`) is not strictly greater than this value, queues can become persistently stopped or stop after minimal use, severely degrading performance. A single sk_buff transmission typically requires descriptors for: - The virtio_net_hdr (1 descriptor) - The sk_buff's linear data (head) (1 descriptor) - Paged fragments (up to MAX_SKB_FRAGS descriptors) This patch enforces that the TX ring size ('ring_num') must be strictly greater than (MAX_SKB_FRAGS + 2). This ensures that the ring is always large enough to hold at least one maximally-fragmented packet plus at least one additional slot.

2025-07-03virtio_ring: Fix error reporting in virtqueue_resizeLaurent Vivier
The virtqueue_resize() function was not correctly propagating error codes from its internal resize helper functions, specifically virtqueue_resize_packet() and virtqueue_resize_split(). If these helpers returned an error, but the subsequent call to virtqueue_enable_after_reset() succeeded, the original error from the resize operation would be masked. Consequently, virtqueue_resize() could incorrectly report success to its caller despite an underlying resize failure. This change restores the original code behavior: if (vdev->config->enable_vq_after_reset(_vq)) return -EBUSY; return err; Fix: commit ad48d53b5b3f ("virtio_ring: separate the logic of reset/enable from virtqueue_resize") Cc: xuanzhuo@linux.alibaba.com Signed-off-by: Laurent Vivier <lvivier@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Link: https://patch.msgid.link/20250521092236.661410-2-lvivier@redhat.com Tested-by: Lei Yang <leiyang@redhat.com> Acked-by: Michael S.

2025-07-03virtio-net: xsk: rx: fix the frame's length checkBui Quang Minh
When calling buf_to_xdp, the len argument is the frame data's length without virtio header's length (vi->hdr_len). We check that len with xsk_pool_get_rx_frame_size() + vi->hdr_len to ensure the provided len does not larger than the allocated chunk size. The additional vi->hdr_len is because in virtnet_add_recvbuf_xsk, we use part of XDP_PACKET_HEADROOM for virtio header and ask the vhost to start placing data from hard_start + XDP_PACKET_HEADROOM - vi->hdr_len not hard_start + XDP_PACKET_HEADROOM But the first buffer has virtio_header, so the maximum frame's length in the first buffer can only be xsk_pool_get_rx_frame_size() not xsk_pool_get_rx_frame_size() + vi->hdr_len like in the current check. This commit adds an additional argument to buf_to_xdp differentiate between the first buffer and other ones to correctly calculate the maximum frame's length.

2025-07-02net/sched: Always pass notifications when child class becomes emptyLion Ackermann
Certain classful qdiscs may invoke their classes' dequeue handler on an enqueue operation. This may unexpectedly empty the child qdisc and thus make an in-flight class passive via qlen_notify(). Most qdiscs do not expect such behaviour at this point in time and may re-activate the class eventually anyways which will lead to a use-after-free. The referenced fix commit attempted to fix this behavior for the HFSC case by moving the backlog accounting around, though this turned out to be incomplete since the parent's parent may run into the issue too. The following reproducer demonstrates this use-after-free: tc qdisc add dev lo root handle 1: drr tc filter add dev lo parent 1: basic classid 1:1 tc class add dev lo parent 1: classid 1:1 drr tc qdisc add dev lo parent 1:1 handle 2: hfsc def 1 tc class add dev lo parent 2: classid 2:1 hfsc rt m1 8 d 1 m2 0 tc qdisc add dev lo parent 2:1 handle 3: netem tc qdisc add dev lo parent 3:1 handle 4: blackhole echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888 tc class delete dev lo classid 1:1 echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888 Since backlog accounting issues leading to a use-after-frees on stale class pointers is a recurring pattern at this point, this patch takes a different approach. Instead of trying to fix the accounting, the patch ensures that qdisc_tree_reduce_backlog always calls qlen_notify when the child qdisc is empty. This solves the problem because deletion of qdiscs always involves a call to qdisc_reset() and / or qdisc_purge_queue() which ultimately resets its qlen to 0 thus causing the following qdisc_tree_reduce_backlog() to report to the parent. Note that this may call qlen_notify on passive classes multiple times. This is not a problem after the recent patch series that made all the classful qdiscs qlen_notify() handlers idempotent.

2025-07-01rose: fix dangling neighbour pointers in rose_rt_device_down()Kohei Enju
There are two bugs in rose_rt_device_down() that can cause use-after-free: 1. The loop bound `t->count` is modified within the loop, which can cause the loop to terminate early and miss some entries. 2. When removing an entry from the neighbour array, the subsequent entries are moved up to fill the gap, but the loop index `i` is still incremented, causing the next entry to be skipped. For example, if a node has three neighbours (A, A, B) with count=3 and A is being removed, the second A is not checked. i=0: (A, A, B) -> (A, B) with count=2 ^ checked i=1: (A, B) -> (A, B) with count=2 ^ checked (B, not A!) i=2: (doesn't occur because i < count is false) This leaves the second A in the array with count=2, but the rose_neigh structure has been freed. Code that accesses these entries assumes that the first `count` entries are valid pointers, causing a use-after-free when it accesses the dangling pointer. Fix both issues by iterating over the array in reverse order with a fixed loop bound. This ensures that all entries are examined and that the removal of an entry doesn't affect subsequent iterations.

2025-07-01igc: disable L1.2 PCI-E link substate to avoid performance issueVitaly Lifshits
I226 devices advertise support for the PCI-E link L1.2 substate. However, due to a hardware limitation, the exit latency from this low-power state is longer than the packet buffer can tolerate under high traffic conditions. This can lead to packet loss and degraded performance. To mitigate this, disable the L1.2 substate. The increased power draw between L1.1 and L1.2 is insignificant.

The `dma_map_XXX()` functions can fail and must be checked using `dma_mapping_error()`. This patch adds proper error handling for all DMA mapping calls. In `atl1_alloc_rx_buffers()`, if DMA mapping fails, the buffer is deallocated and marked accordingly. In `atl1_tx_map()`, previously mapped buffers are unmapped and the packet is dropped on failure. If `atl1_xmit_frame()` drops the packet, increment the tx_error counter. Fixes: f3cc28c79760 ("Add Attansic L1 ethernet driver.")

2025-06-27Bluetooth: HCI: Set extended advertising data synchronouslyChristian Eggers
Currently, for controllers with extended advertising, the advertising data is set in the asynchronous response handler for extended adverstising params. As most advertising settings are performed in a synchronous context, the (asynchronous) setting of the advertising data is done too late (after enabling the advertising). Move setting of adverstising data from asynchronous response handler into synchronous context to fix ordering of HCI commands.

The unconditional call of hci_disable_advertising_sync() in mesh_send_done_sync() also disables other LE advertisings (non mesh related). I am not sure whether this call is required at all, but checking the adv_instances list (like done at other places) seems to solve the problem.

2025-06-27Bluetooth: MGMT: set_mesh: update LE scan interval and windowChristian Eggers
According to the message of commit b338d91703fa ("Bluetooth: Implement support for Mesh"), MGMT_OP_SET_MESH_RECEIVER should set the passive scan parameters. Currently the scan interval and window parameters are silently ignored, although user space (bluetooth-meshd) expects that they can be used [1] [1] https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/mesh/mesh-io-mgmt.c#n344 Fixes: b338d91703fa ("Bluetooth: Implement support for Mesh") Cc: stable@vger.kernel.org Signed-off-by: Christian Eggers <ceggers@arri.de> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

'rx_ring->size' means the count of ring descriptors multiplied by the size of one descriptor. When increasing the count of ring descriptors, it may exceed the limit of pool size.

2025-06-26net: selftests: fix TCP packet checksumJakub Kicinski
The length in the pseudo header should be the length of the L3 payload AKA the L4 header+payload. The selftest code builds the packet from the lower layers up, so all the headers are pushed already when it constructs L4. We need to subtract the lower layer headers from skb->len.
