Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2018-10-03 This series contains updates to ice and virtchnl. Yashaswini Raghuram adds a new virtchnl capability flag to support the exchange of additional supported speeds. Anirudh adds support for SR-IOV for the ice driver. Added code to initialize, configure and use mailbox queues for PF and VF communication. Updated the VSI and queue management to handle both PF and VF VSI type. Added "Adaptive Virtual Function (AVF)" support for the ice PF driver by implementing virtchnl commands. Extended the malicious driver detection logic to include the VF driver as well. Fixed the queue region size which needs to be log base 2 of the number of queues in region. Brett fixes an issue which was causing switch rules to be lost, by making a call to ice_update_pkt_fwd_rule() with the necessary changes. Fixed how the PF and VF assigned the ITR index by adding a struct member itr_idx to be used to dynamically program the correct ITR index. Dave fixed a potential NULL pointer dereference by adding checks in the filter handling. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

This issue came about when looking at the VF function ice_vc_cfg_irq_map_msg. Currently we are assigning the itr_setting value to the itr_idx received from the AVF driver, which is not correct and is not used for the VF flow anyway. Currently the only way we set the ITR index for both the PF and VF driver is by hard coding ICE_TX_ITR or ICE_RX_ITR for the ITR index on each q_vector. To fix this, add the member itr_idx in struct ice_ring_container. This can then be used to dynamically program the correct ITR index. This change also affected the PF driver so make the necessary changes there as well. Also, removed the itr_setting member in struct ice_ring because it is not being used meaningfully and is going to be removed in a future patch that includes dynamic ITR. On another note, this will be useful moving forward if we decide to split Rx/Tx rings on different q_vectors instead of sharing them as queue pairs. Signed-off-by:

Brett Creeley authored
When a switch rule is initially created we set the filter action to ICE_FWD_TO_VSI. The filter action changes to ICE_FWD_TO_VSI_LIST whenever more than one VSI is subscribed to the same switch rule. When the switch rule goes from 2 VSIs in the list to 1 VSI we remove and delete the VSI list rule, but we currently don't update the switch rule in hardware. This is causing switch rules to be lost, so fix that by making a call to ice_update_pkt_fwd_rule() with the necessary changes. Signed-off-by:

virtchnl is a protocol/interface specification that allows the Intel "Adaptive Virtual Function (AVF)" driver (iavf.ko) to work with more than one physical function driver. The AVF driver sends "virtchnl commands" (control plane only) to the PF driver over mailbox queues and the PF driver executes these commands and returns a result to the VF, again over mailbox. This patch adds AVF support for the ice PF driver by implementing the following virtchnl commands: VIRTCHNL_OP_VERSION VIRTCHNL_OP_GET_VF_RESOURCES VIRTCHNL_OP_RESET_VF VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_REQUEST_QUEUES VIRTCHNL_OP_CONFIG_IRQ_MAP VIRTCHNL_OP_CONFIG_RSS_KEY VIRTCHNL_OP_CONFIG_RSS_LUT VIRTCHNL_OP_GET_STATS VIRTCHNL_OP_ADD_VLAN VIRTCHNL_OP_DEL_VLAN VIRTCHNL_OP_ENABLE_VLAN_STRIPPING VIRTCHNL_OP_DISABLE_VLAN_STRIPPING Signed-off-by:

Post VF initialization, there are a couple of different ways in which a VF reset can be triggered. One is when the underlying PF itself goes through a reset and other is via a VFLR interrupt. ice_reset_vf introduced in this patch handles both these cases. Also introduced in this patch is a helper function ice_aq_send_msg_to_vf to send messages to VF over the mailbox queue. The PF uses this to send reset notifications to VFs. Signed-off-by:

This patch implements parts of ice_sriov_configure and VF reset flow. To create virtual functions (VFs), the user sets a value in num_vfs through sysfs. This results in the kernel calling the handler for .sriov_configure which is ice_sriov_configure. VF setup first starts with a VF reset, followed by allocation of the VF VSI using ice_vf_vsi_setup. Once the VF setup is complete a state bit ICE_VF_STATE_INIT is set in the vf->states bitmap to indicate that the VF is ready to go. Also for VF reset to go into effect, it's necessary to issue a disable queue command (ice_aqc_opc_dis_txqs). So this patch updates multiple functions in the disable queue flow to take additional parameters that distinguish if queues are being disabled due to VF reset. Signed-off-by:

Presently, for non-zero copy case, separate pages are allocated for storing plaintext and encrypted text of records. These pages are stored in sg_plaintext_data and sg_encrypted_data scatterlists inside record structure. Further, sg_plaintext_data & sg_encrypted_data are passed to cryptoapis for record encryption. Allocating separate pages for plaintext and encrypted text is inefficient from both required memory and performance point of view. This patch adds support of inplace encryption of records. For non-zero copy case, we reuse the pages from sg_encrypted_data scatterlist to copy the application's plaintext data. For the movement of pages from sg_encrypted_data to sg_plaintext_data scatterlists, we introduce a new function move_to_plaintext_sg(). This function add pages into sg_plaintext_data from sg_encrypted_data scatterlists. tls_do_encryption() is modified to pass the same scatterlist as both source and destination into aead_request_set_crypt() if inplace crypto has been enabled. A new ariable 'inplace_crypto' has been introduced in record structure to signify whether the same scatterlist can be used. By default, the inplace_crypto is enabled in get_rec(). If zero-copy is used (i.e. plaintext data is not copied), inplace_crypto is set to '0'. Signed-off-by:

Similar to other patches from ERic. As diagnosed by Song Liu, ndo_poll_controller() can be very dangerous on loaded hosts, since the cpu calling ndo_poll_controller() might steal all NAPI contexts (for all RX/TX queues of the NIC). This capture can last for unlimited amount of time, since one cpu is generally not able to drain all the queues under load. In netvsc driver it uses NAPI for TX completions. The default poll_napi will do this for us now and avoid the capture. Signed-off-by:

It is useful to be able to use the same socket for listening in a specific VRF, as for sending multicast packets out of a specific interface. However, the bound device on the socket currently takes precedence and results in the packets not being sent. Relax the condition on overriding the output interface to use for sending packets out of UDP, raw and ping sockets to allow multicast packets to be sent using the specified multicast interface.

Commit 13cefad2 ("net: bridge: convert and rename mcast disabled") converted the 'multicast_disabled' field to an option bit named 'BROPT_MULTICAST_ENABLED'. While the old field was implicitly initialized to 0, the new field is not initialized, resulting in the bridge defaulting to multicast disabled state and breaking existing applications. Fix this by explicitly initializing the option. Fixes: 13cefad2 ("net: bridge: convert and rename mcast disabled") Signed-off-by:

Ioana Radulescu says: ==================== dpaa2-eth: Add support for Rx flow classification The Management Complex (MC) firmware initially allowed the configuration of a single key to be used both for Rx flow hashing and flow classification. This prevented us from supporting Rx flow classification independently of the hash key configuration. Newer firmware versions expose separate commands for configuring the two types of keys, so we can use them to introduce Rx classification support. For frames that don't match any classification rule, we fall back to statistical distribution based on the current hash key. The first patch in this set updates the Rx hashing code to use the new firmware API for key config. Subsequent patches introduce the firmware API for configuring the classification and actual support for adding and deleting rules via ethtool. ==================== Signed-off-by: -

Add support for inserting and deleting Rx flow classification rules through ethtool. We support classification based on some header fields for flow-types ether, ip4, tcp4, udp4 and sctp4. Rx queues are core affine, so the action argument effectively selects on which cpu the matching frame will be processed. Discarding the frame is also supported. Signed-off-by:

For firmware versions that support it, configure an Rx flow classification key at probe time. Hardware expects all rules in the classification table to share the same key. So we setup a key containing all supported fields at driver init and when a user adds classification rules through ethtool, we will just mask out the unused header fields. Since the key composition process is the same for flow classification and hashing, reuse existing code where possible. Signed-off-by:
