2024-12-03ice: Fix VLAN pruning in switchdev modeMarcin Szycik
In switchdev mode the uplink VSI should receive all unmatched packets, including VLANs. Therefore, VLAN pruning should be disabled if uplink is in switchdev mode. It is already being done in ice_eswitch_setup_env(), however the addition of ice_up() in commit 44ba608db509 ("ice: do switchdev slow-path Rx using PF VSI") caused VLAN pruning to be re-enabled after disabling it. Add a check to ice_set_vlan_filtering_features() to ensure VLAN filtering will not be enabled if uplink is in switchdev mode. Note that ice_is_eswitch_mode_switchdev() is being used instead of ice_is_switchdev_running(), as the latter would only return true after the whole switchdev setup completes.

2024-11-15ndo_fdb_add: Add a parameter to report whether notification was sentPetr Machata
Currently when FDB entries are added to or deleted from a VXLAN netdevice, the VXLAN driver emits one notification, including the VXLAN-specific attributes. The core however always sends a notification as well, a generic one. Thus two notifications are unnecessarily sent for these operations. A similar situation comes up with bridge driver, which also emits notifications on its own: # ip link add name vx type vxlan id 1000 dstport 4789 # bridge monitor fdb & [1] 1981693 # bridge fdb add de:ad:be:ef:13:37 dev vx self dst 192.0.2.1 de:ad:be:ef:13:37 dev vx dst 192.0.2.1 self permanent de:ad:be:ef:13:37 dev vx self permanent In order to prevent this duplicity, add a paremeter to ndo_fdb_add, bool *notified. The flag is primed to false, and if the callee sends a notification on its own, it sets it to true, thus informing the core that it should not generate another notification.

2024-11-13ice: use stack variable for virtchnl_supported_rxdidsJacob Keller
The ice_vc_query_rxdid() function allocates memory to store the virtchnl_supported_rxdids structure used to communicate the bitmap of supported RXDIDs to a VF. This structure is only 8 bytes in size. The function must hold the allocated length on the stack as well as the pointer to the structure which itself is 8 bytes. Allocating this storage on the heap adds unnecessary overhead including a potential error path that must be handled in case kzalloc fails. Because this structure is so small, we're not saving stack space. Additionally, because we must ensure that we free the allocated memory, the return value from ice_vc_send_msg_to_vf() must also be saved in the stack ret variable. Depending on compiler optimization, this means allocating the 8-byte structure is requiring up to 16-bytes of stack memory! Simplify this function to keep the rxdid variable on the stack, saving memory and removing a potential failure exit path from this function.

2024-11-13ice: initialize pf->supported_rxdids immediately after loading DDPJacob Keller
The pf->supported_rxdids field is used to populate the list of valid RXDIDs that a VF may use when negotiating VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC. The set of supported RXDIDs is dependent on the DDP, and can be read from the GLXFLXP_RXDID_FLAGS register. The PF needs to send this list to the VF upon receiving the VIRTCHNL_OP_GET_SUPPORTED_RXDIDs. It also needs to use this list to validate the requested descriptor ID from the VF when programming the Rx queues. A future update to support VF live migration will also want to validate that the target VF can support the same descriptor ID when migrating. Currently, pf->supported_rxdids is initialized inside the ice_vc_query_rxdid() function. This means that it is only ever initialized if at least one VF actually tries to negotiate VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC. It is also unnecessarily re-initialized every time the VF loads and requests the descriptor list. This worked before because the PF only checks pf->suppported_rxdids when programming the Rx queue if the VF actually negotiates the VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC feature. This will be problematic for VF live migration. We need the list of supported Rx descriptor IDs when migrating. It is possible that no VF on the target PF has ever actually issued a VIRTCHNL_OP_GET_SUPPORTED_RXDIDs. Refactor the driver to initialize pf->supported_rxdids during driver initialization after the DDP is loaded. This is simpler, avoids unnecessary duplicate work, and avoids issues with the live migration process.

2024-11-13ice: only allow Tx promiscuous for multicastBrett Creeley
Currently when any VF is trusted and true promiscuous mode is enabled on the PF, the VF will receive all unicast traffic directed to the device's internal switch. This includes traffic external to the NIC and also from other VSI (i.e. VFs). This does not match the expected behavior as unicast traffic should only be visible from external sources in this case.

2024-11-04ice: change q_index variable type to s16 to store -1 valueMateusz Polchlopek
Fix Flow Director not allowing to re-map traffic to 0th queue when action is configured to drop (and vice versa). The current implementation of ethtool callback in the ice driver forbids change Flow Director action from 0 to -1 and from -1 to 0 with an error, e.g: # ethtool -U eth2 flow-type tcp4 src-ip 1.1.1.1 loc 1 action 0 # ethtool -U eth2 flow-type tcp4 src-ip 1.1.1.1 loc 1 action -1 rmgr: Cannot insert RX class rule: Invalid argument We set the value of `u16 q_index = 0` at the beginning of the function ice_set_fdir_input_set(). In case of "drop traffic" action (which is equal to -1 in ethtool) we store the 0 value. Later, when want to change traffic rule to redirect to queue with index 0 it returns an error caused by duplicate found. Fix this behaviour by change of the type of field `q_index` from u16 to s16 in `struct ice_fdir_fltr`. This allows to store -1 in the field in case of "drop traffic" action. What is more, change the variable type in the function ice_set_fdir_input_set() and assign at the beginning the new `#define ICE_FDIR_NO_QUEUE_IDX` which is -1. Later, if the action is set to another value (point specific queue index) the variable value is overwritten in the function.

2024-11-04ice: Fix use after free during unload with ports in bridgeMarcin Szycik
Unloading the ice driver while switchdev port representors are added to a bridge can lead to kernel panic. Reproducer: modprobe ice devlink dev eswitch set $PF1_PCI mode switchdev ip link add $BR type bridge ip link set $BR up echo 2 > /sys/class/net/$PF1/device/sriov_numvfs sleep 2 ip link set $PF1 master $BR ip link set $VF1_PR master $BR ip link set $VF2_PR master $BR ip link set $PF1 up ip link set $VF1_PR up ip link set $VF2_PR up ip link set $VF1 up rmmod irdma ice When unloading the driver, ice_eswitch_detach() is eventually called as part of VF freeing. First, it removes a port representor from xarray, then unregister_netdev() is called (via repr->ops.rem()), finally representor is deallocated. The problem comes from the bridge doing its own deinit at the same time. unregister_netdev() triggers a notifier chain, resulting in ice_eswitch_br_port_deinit() being called. It should set repr->br_port = NULL, but this does not happen since repr has already been removed from xarray and is not found. Regardless, it finishes up deallocating br_port. At this point, repr is still not freed and an fdb event can happen, in which ice_eswitch_br_fdb_event_work() takes repr->br_port and tries to use it, which causes a panic (use after free). Note that this only happens with 2 or more port representors added to the bridge, since with only one representor port, the bridge deinit is slightly different (ice_eswitch_br_port_deinit() is called via ice_eswitch_br_ports_flush(), not ice_eswitch_br_port_unlink()).

2024-11-03dim: pass dim_sample to net_dim() by referenceCaleb Sander Mateos
net_dim() is currently passed a struct dim_sample argument by value. struct dim_sample is 24 bytes. Since this is greater 16 bytes, x86-64 passes it on the stack. All callers have already initialized dim_sample on the stack, so passing it by value requires pushing a duplicated copy to the stack. Either witing to the stack and immediately reading it, or perhaps dereferencing addresses relative to the stack pointer in a chain of push instructions, seems to perform quite poorly. In a heavy TCP workload, mlx5e_handle_rx_dim() consumes 3% of CPU time, 94% of which is attributed to the first push instruction to copy dim_sample on the stack for the call to net_dim(): // Call ktime_get() 0.26 |4ead2: call 4ead7 <mlx5e_handle_rx_dim+0x47> // Pass the address of struct dim in %rdi |4ead7: lea 0x3d0(%rbx),%rdi // Set dim_sample.pkt_ctr |4eade: mov %r13d,0x8(%rsp) // Set dim_sample.byte_ctr |4eae3: mov %r12d,0xc(%rsp) // Set dim_sample.event_ctr 0.15 |4eae8: mov %bp,0x10(%rsp) // Duplicate dim_sample on the stack 94.16 |4eaed: push 0x10(%rsp) 2.79 |4eaf1: push 0x10(%rsp) 0.07 |4eaf5: push %rax // Call net_dim() 0.21 |4eaf6: call 4eafb <mlx5e_handle_rx_dim+0x6b> To allow the caller to reuse the struct dim_sample already on the stack, pass the struct dim_sample by reference to net_dim().

2024-10-08ice: store max_frame and rx_buf_len only in ice_rx_ringJacob Keller
The max_frame and rx_buf_len fields of the VSI set the maximum frame size for packets on the wire, and configure the size of the Rx buffer. In the hardware, these are per-queue configuration. Most VSI types use a simple method to determine the size of the buffers for all queues. However, VFs may potentially configure different values for each queue. While the Linux iAVF driver does not do this, it is allowed by the virtchnl interface. The current virtchnl code simply sets the per-VSI fields inbetween calls to ice_vsi_cfg_single_rxq(). This technically works, as these fields are only ever used when programming the Rx ring, and otherwise not checked again. However, it is confusing to maintain. The Rx ring also already has an rx_buf_len field in order to access the buffer length in the hotpath. It also has extra unused bytes in the ring structure which we can make use of to store the maximum frame size. Drop the VSI max_frame and rx_buf_len fields. Add max_frame to the Rx ring, and slightly re-order rx_buf_len to better fit into the gaps in the structure layout. Change the ice_vsi_cfg_frame_size function so that it writes to the ring fields. Call this function once per ring in ice_vsi_cfg_rxqs(). This is done over calling it inside the ice_vsi_cfg_rxq(), because ice_vsi_cfg_rxq() is called in the virtchnl flow where the max_frame and rx_buf_len have already been configured. Change the accesses for rx_buf_len and max_frame to all point to the ring structure. This has the added benefit that ice_vsi_cfg_rxq() no longer has the surprise side effect of updating ring->rx_buf_len based on the VSI field. Update the virtchnl ice_vc_cfg_qs_msg() function to set the ring values directly, and drop references to the removed VSI fields. This now makes the VF logic clear, as the ring fields are obviously per-queue. This reduces the required cognitive load when reasoning about this logic. Note that removing the VSI fields does leave a 4 byte gap, but the ice_vsi structure has many gaps, and its layout is not as critical in the hot path. The structure may benefit from a more thorough repacking, but no attempt was made in this change.

2024-10-08ice: consistently use q_idx in ice_vc_cfg_qs_msg()Jacob Keller
The ice_vc_cfg_qs_msg() function is used to configure VF queues in response to a VIRTCHNL_OP_CONFIG_VSI_QUEUES command. The virtchnl command contains an array of queue pair data for configuring Tx and Rx queues. This data includes a queue ID. When configuring the queues, the driver generally uses this queue ID to determine which Tx and Rx ring to program. However, a handful of places use the index into the queue pair data from the VF. While most VF implementations appear to send this data in order, it is not mandated by the virtchnl and it is not verified that the queue pair data comes in order. Fix the driver to consistently use the q_idx field instead of the 'i' iterator value when accessing the rings. For the Rx case, introduce a local ring variable to keep lines short.

Reproducer: modprobe ice echo 0 > /sys/bus/pci/devices/$PF_PCI/sriov_drivers_autoprobe echo 1 > /sys/bus/pci/devices/$PF_PCI/sriov_numvfs echo 17 > /sys/bus/pci/devices/$VF0_PCI/sriov_vf_msix_count Default MSI-X is 16, so 17 and above triggers this issue.

To fix it, use ice_vsi_rebuild() instead of ice_vf_reconfig_vsi(). This causes the required arrays to be reallocated taking the new queue count into account (ice_vsi_realloc_stat_arrays()). Set req_txq and req_rxq before ice_vsi_rebuild(), so that realloc uses the newly set queue count. Additionally, ice_vsi_rebuild() does not remove VSI filters (ice_fltr_remove_all()), so ice_vf_init_host_cfg() is no longer necessary.

2024-10-08ice: Flush FDB entries before resetWojciech Drewek
Triggering the reset while in switchdev mode causes errors[1]. Rules are already removed by this time because switch content is flushed in case of the reset. This means that rules were deleted from HW but SW still thinks they exist so when we get SWITCHDEV_FDB_DEL_TO_DEVICE notification we try to delete not existing rule. We can avoid these errors by clearing the rules early in the reset flow before they are removed from HW. Switchdev API will get notified that the rule was removed so we won't get SWITCHDEV_FDB_DEL_TO_DEVICE notification. Remove unnecessary ice_clear_sw_switch_recipes.

2024-10-08ice: Fix netif_is_ice() in Safe ModeMarcin Szycik
netif_is_ice() works by checking the pointer to netdev ops. However, it only checks for the default ice_netdev_ops, not ice_netdev_safe_mode_ops, so in Safe Mode it always returns false, which is unintuitive. While it doesn't look like netif_is_ice() is currently being called anywhere in Safe Mode, this could change and potentially lead to unexpected behaviour.

2024-10-01ice: Use ice_adapter for PTP shared data instead of auxdevSergey Temerkhanov
Use struct ice_adapter to hold shared PTP data and control PTP related actions instead of auxbus. This allows significant code simplification and faster access to the container fields used in the PTP support code. Move the PTP port list to the ice_adapter container to simplify the code and avoid race conditions which could occur due to the synchronous nature of the initialization/access and certain memory saving can be achieved by moving PTP data into the ice_adapter itself.
