10 daysice: fix ICE_AQ_LINK_SPEED_M for 200GPaul Greenwalt
When setting PHY configuration during driver initialization, 200G link speed is not being advertised even when the PHY is capable. This is because the get PHY capabilities link speed response is being masked by ICE_AQ_LINK_SPEED_M, which does not include the 200G link speed bit. ICE_AQ_LINK_SPEED_200GB is defined as BIT(11), but the mask 0x7FF only covers bits 0-10. Fix ICE_AQ_LINK_SPEED_M to use GENMASK(11, 0) so that it covers all defined link speed bits including 200G.

10 daysice: fix PHY config on media change with link-down-on-closePaul Greenwalt
Commit 1a3571b5938c ("ice: restore PHY settings on media insertion") introduced separate flows for setting PHY configuration on media present: ice_configure_phy() when link-down-on-close is disabled, and ice_force_phys_link_state() when enabled. The latter incorrectly uses the previous configuration even after module change, causing link issues such as wrong speed or no link. Unify PHY configuration into a single ice_phy_cfg() function with a link_en parameter, ensuring PHY capabilities are always fetched fresh from hardware.

10 daysice: fix double-free of tx_buf skbMichal Schmidt
If ice_tso() or ice_tx_csum() fail, the error path in ice_xmit_frame_ring() frees the skb, but the 'first' tx_buf still points to it and is marked as valid (ICE_TX_BUF_SKB). 'next_to_use' remains unchanged, so the potential problem will likely fix itself when the next packet is transmitted and the tx_buf gets overwritten. But if there is no next packet and the interface is brought down instead, ice_clean_tx_ring() -> ice_unmap_and_free_tx_buf() will find the tx_buf and free the skb for the second time. The fix is to reset the tx_buf type to ICE_TX_BUF_EMPTY in the error path, so that ice_unmap_and_free_tx_buf(). Move the initialization of 'first' up, to ensure it's already valid in case we hit the linearization error path. The bug was spotted by AI while I had it looking for something else. It also proposed an initial version of the patch. I reproduced the bug and tested the fix by adding code to inject failures, on a build with KASAN. I looked for similar bugs in related Intel drivers and did not find any.

10 daysice: fix double free in ice_sf_eth_activate() error pathGuangshuo Li
When auxiliary_device_add() fails, ice_sf_eth_activate() jumps to aux_dev_uninit and calls auxiliary_device_uninit(&sf_dev->adev). The device release callback ice_sf_dev_release() frees sf_dev, but the current error path falls through to sf_dev_free and calls kfree(sf_dev) again, causing a double free. Keep kfree(sf_dev) for the auxiliary_device_init() failure path, but avoid falling through to sf_dev_free after auxiliary_device_uninit().

11 daysnet: enetc: fix NTMP DMA use-after-free issueWei Fang
The AI-generated review reported a potential DMA use-after-free issue [1]. If netc_xmit_ntmp_cmd() times out and returns an error, the pending command is not explicitly aborted, while ntmp_free_data_mem() unconditionally frees the DMA buffer. If the buffer has already been reallocated elsewhere, this may lead to silent memory corruption. Because the hardware eventually processes the pending command and perform a DMA write of the response to the physical address of the freed buffer. To resolve this issue, this patch does the following modifications: 1. Convert cbdr->ring_lock from a spinlock to a mutex The lock was originally a spinlock in case NTMP operations might be invoked from atomic context. After downstream support for all NTMP tables, no such usage has materialized. A mutex lock is now required because the driver now needs to reclaim used BDs and release associated DMA memory within the lock's context, while dma_free_coherent() might sleep. 2. Introduce software command BD (struct netc_swcbd) The hardware write-back overwrites the addr and len fields of the BD, so the driver cannot rely on the hardware BD to free the associated DMA memory. The driver now maintains a software shadow BD storing the DMA buffer pointer, DMA address, and size. And netc_xmit_ntmp_cmd() only reclaims older BDs when the number of used BDs reaches NETC_CBDR_CLEAN_WORK (16). The software BD enables correct DMA memory release. With this, struct ntmp_dma_buf and ntmp_free_data_mem() are no longer needed and are removed. 3. Require callers to hold ring_lock across netc_xmit_ntmp_cmd() netc_xmit_ntmp_cmd() releases the ring_lock before the caller finishes consuming the response. At this point, if a concurrent thread submits a new command, it may trigger ntmp_clean_cbdr() and free the DMA buffer while it is still in use. Move ring_lock ownership to the caller to ensure the response buffer cannot be reclaimed prematurely. So the helpers ntmp_select_and_lock_cbdr() and ntmp_unlock_cbdr() are added. These changes eliminate the DMA use-after-free condition and ensure safe and consistent BD reclamation and DMA buffer lifecycle management.

11 daysnet: enetc: correct the command BD ring consumer indexWei Fang
The command BD ring cousumer index register has the consumer index as the lower 10 bits, and the bit 31 is SBE, which indicates whether a system bus error occurred during execution of the CBD command. So if a system bus error occurs, reading the register will get the SBE bit set. However, the current implementation directly uses the register value as the consumer index without masking it. Therefore, if a system bus error occurs, an incorrect consumer index will be obtained, causing errors in the processing of the command BD ring. Thus, we need to mask out the other bits to obtain the correct consumer index. In addition, this patch adds a check for the SBE bit after the polling loop and returns an error if the bit is set.

Add the following PPE configuration in airoha_ppe_hw_init routine: - 6RD hw offloading is currently not supported by Netfilter flowtable. Disable explicitly PPE 6RD offloading in order to prevent PPE to learn 6RD flows and eventually interrupt the traffic. - Add missing PPE bind rate configuration for L3 and L2 traffic. PPE bind rate configuration specifies the pps threshold to move a PPE entry state from UNBIND to BIND.

2026-04-13bnge: return after auxiliary_device_uninit() in error pathGreg Kroah-Hartman
When auxiliary_device_add() fails, the error block calls auxiliary_device_uninit() but does not return. The uninit drops the last reference and synchronously runs bnge_aux_dev_release(), which sets bd->auxr_dev = NULL and frees the underlying object. The subsequent bd->auxr_dev->net = bd->netdev then dereferences NULL, which is not a good thing to have happen when trying to clean up from an error. Add the missing return, as the auxiliary bus documentation states is a requirement (seems that LLM tools read documentation better than humans do...)

2026-04-12net: ethernet: mtk_eth_soc: initialize PPE per-tag-layer MTU registersDaniel Golle
The PPE enforces output frame size limits via per-tag-layer VLAN_MTU registers that the driver never initializes. The hardware defaults do not account for PPPoE overhead, causing the PPE to punt encapsulated frames back to the CPU instead of forwarding them. Initialize the registers at PPE start and on MTU changes using the maximum GMAC MTU. This is a conservative approximation -- the actual per-PPE requirement depends on egress path, but using the global maximum ensures the limits are never too small.

2026-04-12net/mlx5e: IPsec, fix ASO poll timeout with read_poll_timeout_atomic()Gal Pressman
The do-while poll loop uses jiffies for its timeout: expires = jiffies + msecs_to_jiffies(10); jiffies is sampled at an arbitrary point within the current tick, so the first partial tick contributes anywhere from a full tick down to nearly zero real time. For small msecs_to_jiffies() results this is significant, the effective poll window can be much shorter than the requested 10ms, and in the worst case the loop exits after a single iteration (e.g., when HZ=100), well before the device has delivered the CQE. Replace the loop with read_poll_timeout_atomic(), which counts elapsed time via udelay() accounting rather than jiffies, guaranteeing the full poll window regardless of HZ. Additionally, read_poll_timeout_atomic() executes the poll operation one more time after the timeout has expired, giving the CQE a final chance to be detected. The old do-while loop could exit without a final poll if the timeout expired during the udelay() between iterations.

It is not trivial to distinguish between both cases as we cannot use priv to carry state, and in both cases reg_state == NETREG_REGISTERED. Force a netdev features update after register_netdev() completes, where the device is present and fix_features() can actually work. This is not a pretty solution, as it results in an additional features update call (register_netdevice() already calls __netdev_update_features() internally), but it is the simplest, cleanest, and most robust way I found to fix this issue after multiple attempts. This fixes an issue on systems where CQE compression is enabled by default, RXHASH remains enabled after registration despite the two features being mutually exclusive.

2026-04-12net: enetc: show RX drop counters only for assigned RX ringsWei Fang
For ENETC v1, each SI provides 16 RBDCR registers for RX ring drop counters, but this does not imply that an SI actually owns 16 RX rings. The ENETC hardware supports a total of 16 RX rings, which are assigned to 3 SIs (1 PSI and 2 VSIs), so each SI is assigned fewer than 16 RX rings. The current implementation always reports 16 RX drop counters per SI, leading to redundant output for SIs with fewer RX rings. Update the logic to display drop counters only for the RX rings that are actually assigned to the SI.

Use pci_name(pdev) for the per-device debugfs directory instead of hardcoded "0" for PFs and pci_slot_name(pdev->slot) for VFs. The previous approach had two issues: 1. pci_slot_name() dereferences pdev->slot, which can be NULL for VFs in environments like generic VFIO passthrough or nested KVM, causing a NULL pointer dereference. 2. Multiple PFs would all use "0", and VFs across different PCI domains or buses could share the same slot name, leading to -EEXIST errors from debugfs_create_dir(). pci_name(pdev) returns the unique BDF address, is always valid, and is unique across the system.
