Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2018-10-03 This series contains updates to ixgbe/ixgbevf and few fixes for i40e & iavf. Shannon Nelson fixes the message length for IPsec mailbox messages. Radoslaw fixes a transmit hang that occurs when XDP_TX exceeds the queue limit. Fixes a crash when we restor flow director filters after a reset. YueHaibing cleans up dead code, which did not have any callers. Dan Carpenter fixes an "off by one" error in IPsec for ixgbe. Nathan Chancellor fixes the i40e driver to use the correct enum for link speed. Also remove a debug statement since it was not producing useful information and equated to always "TRUE". Most notably, Björn introduces zero-copy AF_XDP support for the ixgbe driver. The ixgbe zero-copy code is located in its own file ixgbe_xsk.[ch], analogous to the i40e ZC support. Again, as in i40e, code paths have been copied from the XDP path to the zero-copy path. Going forward we will try to generalize more code between the AF_XDP ZC drivers, and also reduce the heavy C&P. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2018-10-03ixgbe: add AF_XDP zero-copy Tx supportBjörn Töpel3-1/+195
This patch adds zero-copy Tx support for AF_XDP sockets. It implements the ndo_xsk_async_xmit netdev ndo and performs all the Tx logic from a NAPI context. This means pulling egress packets from the Tx ring, placing the frames on the NIC HW descriptor ring and completing sent frames back to the application via the completion ring. The regular XDP Tx ring is used for AF_XDP as well. This rationale for this is as follows: XDP_REDIRECT guarantees mutual exclusion between different NAPI contexts based on CPU id. In other words, a netdev can XDP_REDIRECT to another netdev with a different NAPI context, since the operation is bound to a specific core and each core has its own hardware ring. As the AF_XDP Tx action is running in the same NAPI context and using the same ring, it will also be protected from XDP_REDIRECT actions with the exact same mechanism. As with AF_XDP Rx, all AF_XDP Tx specific functions are added to ixgbe_xsk.c.

This patch adds zero-copy Rx support for AF_XDP sockets. Instead of allocating buffers of type MEM_TYPE_PAGE_SHARED, the Rx frames are allocated as MEM_TYPE_ZERO_COPY when AF_XDP is enabled for a certain queue. All AF_XDP specific functions are added to a new file, ixgbe_xsk.c. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack.

2018-10-03ice: Add more flexibility on how we assign an ITR indexBrett Creeley3-47/+59
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.

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.

2018-10-03ice: Implement virtchnl commands for AVF supportAnirudh Venkataramanan6-0/+1221
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: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

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.

2018-10-03ice: Add handler to configure SR-IOVAnirudh Venkataramanan11-9/+1061
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.

2018-10-03media: v4l: event: Prevent freeing event subscriptions while accessedSakari Ailus3-18/+26
The event subscriptions are added to the subscribed event list while holding a spinlock, but that lock is subsequently released while still accessing the subscription object. This makes it possible to unsubscribe the event --- and freeing the subscription object's memory --- while the subscription object is simultaneously accessed. Prevent this by adding a mutex to serialise the event subscription and unsubscription. This also gives a guarantee to the callback ops that the add op has returned before the del op is called. This change also results in making the elems field less special: subscriptions are only added to the event list once they are fully initialised.

2018-10-02tls: Add support for inplace records encryptionVakul Garg2-18/+74
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'.

2018-10-02hv_netvsc: remove ndo_poll_controllerStephen Hemminger1-23/+0
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.
