2020-10-30net/mlx5: Replace zero-length array with flexible-array memberGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

2020-10-26RDMA/mlx5: Fix devlink deadlock on net namespace deletionParav Pandit
When a mlx5 core devlink instance is reloaded in different net namespace, its associated IB device is deleted and recreated. Example sequence is: $ ip netns add foo $ devlink dev reload pci/0000:00:08.0 netns foo $ ip netns del foo mlx5 IB device needs to attach and detach the netdevice to it through the netdev notifier chain during load and unload sequence. A below call graph of the unload flow. cleanup_net() down_read(&pernet_ops_rwsem); <- first sem acquired ops_pre_exit_list() pre_exit() devlink_pernet_pre_exit() devlink_reload() mlx5_devlink_reload_down() mlx5_unload_one() [...] mlx5_ib_remove() mlx5_ib_unbind_slave_port() mlx5_remove_netdev_notifier() unregister_netdevice_notifier() down_write(&pernet_ops_rwsem);<- recurrsive lock Hence, when net namespace is deleted, mlx5 reload results in deadlock. When deadlock occurs, devlink mutex is also held. This not only deadlocks the mlx5 device under reload, but all the processes which attempt to access unrelated devlink devices are deadlocked. Hence, fix this by mlx5 ib driver to register for per net netdev notifier instead of global one, which operats on the net namespace without holding the pernet_ops_rwsem.

2020-10-02net/mlx5: cmdif, Avoid skipping reclaim pages if FW is not accessibleSaeed Mahameed
In case of pci is offline reclaim_pages_cmd() will still try to call the FW to release FW pages, cmd_exec() in this case will return a silent success without actually calling the FW. This is wrong and will cause page leaks, what we should do is to detect pci offline or command interface un-available before tying to access the FW and manually release the FW pages in the driver. In this patch we share the code to check for FW command interface availability and we call it in sensitive places e.g. reclaim_pages_cmd(). Alternative fix: 1. Remove MLX5_CMD_OP_MANAGE_PAGES form mlx5_internal_err_ret_value, command success simulation list. 2. Always Release FW pages even if cmd_exec fails in reclaim_pages_cmd().

2020-10-02net/mlx5: Avoid possible free of command entry while timeout comp handlerEran Ben Elisha
Upon command completion timeout, driver simulates a forced command completion. In a rare case where real interrupt for that command arrives simultaneously, it might release the command entry while the forced handler might still access it. Fix that by adding an entry refcount, to track current amount of allowed handlers. Command entry to be released only when this refcount is decremented to zero. Command refcount is always initialized to one. For callback commands, command completion handler is the symmetric flow to decrement it. For non-callback commands, it is wait_func(). Before ringing the doorbell, increment the refcount for the real completion handler. Once the real completion handler is called, it will decrement it. For callback commands, once the delayed work is scheduled, increment the refcount. Upon callback command completion handler, we will try to cancel the timeout callback. In case of success, we need to decrement the callback refcount as it will never run. In addition, gather the entry index free and the entry free into a one flow for all command types release.

2020-09-15net/mlx5e: Add CQE compression support for multi-strides packetsOfer Levi
Add CQE compression support for completions of packets that span multiple strides in a Striding RQ, per the HW capability. In our memory model, we use small strides (256B as of today) for the non-linear SKB mode. This feature allows CQE compression to work also for multiple strides packets. In this case decompressing the mini CQE array will use stride index provided by HW as part of the mini CQE. Before this feature, compression was possible only for single-strided packets, i.e. for packets of size up to 256 bytes when in non-linear mode, and the index was maintained by SW. This feature is supported for ConnectX-5 and above. Feature performance test: This was whitebox-tested, we reduced the PCI speed from 125Gb/s to 62.5Gb/s to overload pci and manipulated mlx5 driver to drop incoming packets before building the SKB to achieve low cpu utilization. Outcome is low cpu utilization and bottleneck on pci only. Test setup: Server: Intel(R) Xeon(R) Silver 4108 CPU @ 1.80GHz server, 32 cores NIC: ConnectX-6 DX. Sender side generates 300 byte packets at full pci bandwidth. Receiver side configuration: Single channel, one cpu processing with one ring allocated. Cpu utilization is ~20% while pci bandwidth is fully utilized. For the generated traffic and interface MTU of 4500B (to activate the non-linear SKB mode), packet rate improvement is about 19% from ~17.6Mpps to ~21Mpps. Without this feature, counters show no CQE compression blocks for this setup, while with the feature, counters show ~20.7Mpps compressed CQEs in ~500K compression blocks.

2020-07-28net/mlx5e: Modify uplink state on interface up/downRon Diskin
When setting the PF interface up/down, notify the firmware to update uplink state via MODIFY_VPORT_STATE, when E-Switch is enabled. This behavior will prevent sending traffic out on uplink port when PF is down, such as sending traffic from a VF interface which is still up. Currently when calling mlx5e_open/close(), the driver only sends PAOS command to notify the firmware to set the physical port state to up/down, however, it is not sufficient. When VF is in "auto" state, it follows the uplink state, which was not updated on mlx5e_open/close() before this patch. When switchdev mode is enabled and uplink representor is first enabled, set the uplink port state value back to its FW default "AUTO".

Instead, have a page data-base per function, which will improve performance release flow in all cases, especially for "release all pages". As the range of function IDs is large and not sequential, use xarray to store a per function ID page data-base, where the function ID is the key.

2020-07-03net/mlx5: Enable QP number request when creating IPoIB underlay QPMichael Guralnik
If in the process of creating the underlay QP for an IPoIB interface the user has set the address and specifically the 1st-3rd bytes representing the QP number, use the requested QP number when creating the underlay QP. For a user to be able to request a QP number on QP creation, the MKEY_BY_NAME NVCONFIG should be set. As mkey_by_name and qp_by_name are coupled in FW. This requires driver to query the mkey_by_name max cap during initialization and set the current cap if it was enabled in FW.

Pull rdma updates from Jason Gunthorpe: "A more active cycle than most of the recent past, with a few large, long discussed works this time. The RNBD block driver has been posted for nearly two years now, and flowing through RDMA due to it also introducing a new ULP. The removal of FMR has been a recurring discussion theme for a long time. And the usual smattering of features and bug fixes. Summary: - Various small driver bugs fixes in rxe, mlx5, hfi1, and efa - Continuing driver cleanups in bnxt_re, hns - Big cleanup of mlx5 QP creation flows - More consistent use of src port and flow label when LAG is used and a mlx5 implementation - Additional set of cleanups for IB CM - 'RNBD' network block driver and target. This is a network block RDMA device specific to ionos's cloud environment. It brings strong multipath and resiliency capabilities. - Accelerated IPoIB for HFI1 - QP/WQ/SRQ ioctl migration for uverbs, and support for multiple async fds - Support for exchanging the new IBTA defiend ECE data during RDMA CM exchanges - Removal of the very old and insecure FMR interface from all ULPs and drivers.

2020-06-03RDMA/mlx5: Return ECE DC supportLeon Romanovsky
The DC QPs are many-to-one QP types that means that first connection will establish ECE options that coming connections should follow. Due to this property, the ECE code was removed between first [1] and second [2] ECE submissions. This patch returns the dropped code, because ECE is a property of a connection and like any other connection users are needed to manage this data. Allow them to set ECE parameter for DC too and avoid need of having compatibility flag for the DC ECE.
