6 dayse1000: Move cancel_work_sync to avoid deadlockJoe Damato
Previously, e1000_down called cancel_work_sync for the e1000 reset task (via e1000_down_and_stop), which takes RTNL. As reported by users and syzbot, a deadlock is possible in the following scenario: CPU 0: - RTNL is held - e1000_close - e1000_down - cancel_work_sync (cancel / wait for e1000_reset_task()) CPU 1: - process_one_work - e1000_reset_task - take RTNL To remedy this, avoid calling cancel_work_sync from e1000_down (e1000_reset_task does nothing if the device is down anyway). Instead, call cancel_work_sync for e1000_reset_task when the device is being removed.

6 daysi40e: retry VFLR handling if there is ongoing VF resetRobert Malz
When a VFLR interrupt is received during a VF reset initiated from a different source, the VFLR may be not fully handled. This can leave the VF in an undefined state. To address this, set the I40E_VFLR_EVENT_PENDING bit again during VFLR handling if the reset is not yet complete. This ensures the driver will properly complete the VF reset in such scenarios.

6 daysi40e: return false from i40e_reset_vf if reset is in progressRobert Malz
The function i40e_vc_reset_vf attempts, up to 20 times, to handle a VF reset request, using the return value of i40e_reset_vf as an indicator of whether the reset was successfully triggered. Currently, i40e_reset_vf always returns true, which causes new reset requests to be ignored if a different VF reset is already in progress. This patch updates the return value of i40e_reset_vf to reflect when another VF reset is in progress, allowing the caller to properly use the retry mechanism.

13 daysiavf: get rid of the crit lockPrzemek Kitszel
Get rid of the crit lock. That frees us from the error prone logic of try_locks. Thanks to netdev_lock() by Jakub it is now easy, and in most cases we were protected by it already - replace crit lock by netdev lock when it was not the case. Lockdep reports that we should cancel the work under crit_lock [splat1], and that was the scheme we have mostly followed since [1] by Slawomir. But when that is done we still got into deadlocks [splat2]. So instead we should look at the bigger problem, namely "weird locking/scheduling" of the iavf. The first step to fix that is to remove the crit lock. I will followup with a -next series that simplifies scheduling/tasks. Cancel the work without netdev lock (weird unlock+lock scheme), to fix the [splat2] (which would be totally ugly if we would kept the crit lock). Extend protected part of iavf_watchdog_task() to include scheduling more work. Note that the removed comment in iavf_reset_task() was misplaced, it belonged to inside of the removed if condition, so it's gone now.

Fix an obvious violation of lock ordering. Jakub's [1] added netdev_lock() call that is wrong ordered wrt RTNL, but the Fixes tag points to crit_lock being wrongly placed (by lockdep standards).

2025-05-30idpf: fix a race in txq wakeupBrian Vazquez
Add a helper function to correctly handle the lockless synchronization when the sender needs to block. The paradigm is if (no_resources()) { stop_queue(); barrier(); if (!no_resources()) restart_queue(); } netif_subqueue_maybe_stop already handles the paradigm correctly, but the code split the check for resources in three parts, the first one (descriptors) followed the protocol, but the other two (completions and tx_buf) were only doing the first part and so race prone. Luckily netif_subqueue_maybe_stop macro already allows you to use a function to evaluate the start/stop conditions so the fix only requires the right helper function to evaluate all the conditions at once. The patch removes idpf_tx_maybe_stop_common since it's no longer needed and instead adjusts separately the conditions for singleq and splitq. Note that idpf_tx_buf_hw_update doesn't need to check for resources since that will be covered in idpf_tx_splitq_frame.

2025-05-30ice: fix rebuilding the Tx scheduler tree for large queue countsMichal Kubiak
The current implementation of the Tx scheduler allows the tree to be rebuilt as the user adds more Tx queues to the VSI. In such a case, additional child nodes are added to the tree to support the new number of queues. Unfortunately, this algorithm does not take into account that the limit of the VSI support node may be exceeded, so an additional node in the VSI layer may be required to handle all the requested queues. Such a scenario occurs when adding XDP Tx queues on machines with many CPUs. Although the driver still respects the queue limit returned by the FW, the Tx scheduler was unable to add those queues to its tree and returned one of the errors below. Such a scenario occurs when adding XDP Tx queues on machines with many CPUs (e.g. at least 321 CPUs, if there is already 128 Tx/Rx queue pairs). Although the driver still respects the queue limit returned by the FW, the Tx scheduler was unable to add those queues to its tree and returned the following errors: Failed VSI LAN queue config for XDP, error: -5 or: Failed to set LAN Tx queue context, error: -22 Fix this problem by extending the tree rebuild algorithm to check if the current VSI node can support the requested number of queues. If it cannot, create as many additional VSI support nodes as necessary to handle all the required Tx queues. Symmetrically, adjust the VSI node removal algorithm to remove all nodes associated with the given VSI. Also, make the search for the next free VSI node more restrictive. That is, add queue group nodes only to the VSI support nodes that have a matching VSI handle. Finally, fix the comment describing the tree update algorithm to better reflect the current scenario.

2025-05-30ice: create new Tx scheduler nodes for new queues onlyMichal Kubiak
The current implementation of the Tx scheduler tree attempts to create nodes for all Tx queues, ignoring the fact that some queues may already exist in the tree. For example, if the VSI already has 128 Tx queues and the user requests for 16 new queues, the Tx scheduler will compute the tree for 272 queues (128 existing queues + 144 new queues), instead of 144 queues (128 existing queues and 16 new queues). Fix that by modifying the node count calculation algorithm to skip the queues that already exist in the tree.

2025-05-30ice: fix Tx scheduler error handling in XDP callbackMichal Kubiak
When the XDP program is loaded, the XDP callback adds new Tx queues. This means that the callback must update the Tx scheduler with the new queue number. In the event of a Tx scheduler failure, the XDP callback should also fail and roll back any changes previously made for XDP preparation. The previous implementation had a bug that not all changes made by the XDP callback were rolled back. This caused the crash with the following call trace: [ +9.549584] ice 0000:ca:00.0: Failed VSI LAN queue config for XDP, error: -5 [ +0.382335] Oops: general protection fault, probably for non-canonical address 0x50a2250a90495525: 0000 [#1] SMP NOPTI [ +0.010710] CPU: 103 UID: 0 PID: 0 Comm: swapper/103 Not tainted 6.14.0-net-next-mar-31+ #14 PREEMPT(voluntary) [ +0.010175] Hardware name: Intel Corporation M50CYP2SBSTD/M50CYP2SBSTD, BIOS SE5C620.86B.01.01.0005.2202160810 02/16/2022 [ +0.010946] RIP: 0010:__ice_update_sample+0x39/0xe0 [ice] [...] [ +0.002715] Call Trace: [ +0.002452] <IRQ> [ +0.002021] ? __die_body.cold+0x19/0x29 [ +0.003922] ? die_addr+0x3c/0x60 [ +0.003319] ? exc_general_protection+0x17c/0x400 [ +0.004707] ? asm_exc_general_protection+0x26/0x30 [ +0.004879] ? __ice_update_sample+0x39/0xe0 [ice] [ +0.004835] ice_napi_poll+0x665/0x680 [ice] [ +0.004320] __napi_poll+0x28/0x190 [ +0.003500] net_rx_action+0x198/0x360 [ +0.003752] ? update_rq_clock+0x39/0x220 [ +0.004013] handle_softirqs+0xf1/0x340 [ +0.003840] ? sched_clock_cpu+0xf/0x1f0 [ +0.003925] __irq_exit_rcu+0xc2/0xe0 [ +0.003665] common_interrupt+0x85/0xa0 [ +0.003839] </IRQ> [ +0.002098] <TASK> [ +0.002106] asm_common_interrupt+0x26/0x40 [ +0.004184] RIP: 0010:cpuidle_enter_state+0xd3/0x690 Fix this by performing the missing unmapping of XDP queues from q_vectors and setting the XDP rings pointer back to NULL after all those queues are released.

idpf_features_check is used to validate the TX packet. skb header length is compared with the hardware supported value received from the device control plane. The value is stored in the adapter structure and to access it, vport pointer is used. During reset all the vports are released and the vport pointer that the netdev private structure points to is NULL. To avoid null-ptr-deref, store the max header length value in netdev private structure. This also helps to cache the value and avoid accessing adapter pointer in hot path.

2025-05-19ice: Fix LACP bonds without SRIOV environmentDave Ertman
If an aggregate has the following conditions: - The SRIOV LAG DDP package has been enabled - The bond is in 802.3ad LACP mode - The bond is disqualified from supporting SRIOV VF LAG - Both interfaces were added simultaneously to the bond (same command) Then there is a chance that the two interfaces will be assigned different LACP Aggregator ID's. This will cause a failure of the LACP control over the bond. To fix this, we can detect if the primary interface for the bond (as defined by the driver) is not in switchdev mode, and exit the setup flow if so. Reproduction steps: %> ip link add bond0 type bond mode 802.3ad miimon 100 %> ip link set bond0 up %> ifenslave bond0 eth0 eth1 %> cat /proc/net/bonding/bond0 | grep Agg Check for Aggregator IDs that differ.

2025-05-19ice: fix vf->num_mac count with port representorsJacob Keller
The ice_vc_repr_add_mac() function indicates that it does not store the MAC address filters in the firmware. However, it still increments vf->num_mac. This is incorrect, as vf->num_mac should represent the number of MAC filters currently programmed to firmware. Indeed, we only perform this increment if the requested filter is a unicast address that doesn't match the existing vf->hw_lan_addr. In addition, ice_vc_repr_del_mac() does not decrement the vf->num_mac counter. This results in the counter becoming out of sync with the actual count. As it turns out, vf->num_mac is currently only used in legacy made without port representors. The single place where the value is checked is for enforcing a filter limit on untrusted VFs. Upcoming patches to support VF Live Migration will use this value when determining the size of the TLV for MAC address filters. Fix the representor mode function to stop incrementing the counter incorrectly.

2025-05-06ice: use DSN instead of PCI BDF for ice_adapter indexPrzemek Kitszel
Use Device Serial Number instead of PCI bus/device/function for the index of struct ice_adapter. Functions on the same physical device should point to the very same ice_adapter instance, but with two PFs, when at least one of them is PCI-e passed-through to a VM, it is no longer the case - PFs will get seemingly random PCI BDF values, and thus indices, what finally leds to each of them being on their own instance of ice_adapter. That causes them to don't attempt any synchronization of the PTP HW clock usage, or any other future resources. DSN works nicely in place of the index, as it is "immutable" in terms of virtualization.
