2022-07-29Merge branch 'mlx5e-use-tls-tx-pool-to-improve-connection-rate'Jakub Kicinski7-102/+527
Tariq Toukan says: ==================== mlx5e use TLS TX pool to improve connection rate To offload encryption operations, the mlx5 device maintains state and keeps track of every kTLS device-offloaded connection. Two HW objects are used per TX context of a kTLS offloaded connection: a. Transport interface send (TIS) object, to reach the HW context. b. Data Encryption Key (DEK) to perform the crypto operations. These two objects are created and destroyed per TLS TX context, via FW commands. In total, 4 FW commands are issued per TLS TX context, which seriously limits the connection rate. In this series, we aim to save creation and destroy of TIS objects by recycling them. Upon recycling of a TIS, the HW still needs to be notified for the re-mapping between a TIS and a context. This is done by posting WQEs via an SQ, significantly faster API than the FW command interface. A pool is used for recycling. The pool dynamically interacts to the load and connection rate, growing and shrinking accordingly. Saving the TIS FW commands per context increases connection rate by ~42%, from 11.6K to 16.5K connections per sec. Connection rate is still limited by FW bottleneck due to the remaining per context FW commands (DEK create/destroy). This will soon be addressed in a followup series. By combining the two series, the FW bottleneck will be released, and a significantly higher (about 100K connections per sec) kTLS TX device-offloaded connection rate is reached. ==================== Link: https://lore.kernel.org/r/20220727094346.10540-1-tariqt@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-29net/mlx5e: kTLS, Dynamically re-size TX recycling poolTariq Toukan1-26/+289
Let the TLS TX recycle pool be more flexible in size, by continuously and dynamically allocating and releasing HW resources in response to changes in the connections rate and load. Allocate and release pool entries in bulks (16). Use a workqueue to release/allocate in the background. Allocate a new bulk when the pool size goes lower than the low threshold (1K). Symmetric operation is done when the pool size gets greater than the upper threshold (4K). Every idle pool entry holds: 1 TIS, 1 DEK (HW resources), in addition to ~100 bytes in host memory. Start with an empty pool to minimize memory and HW resources waste for non-TLS users that have the device-offload TLS enabled. Upon a new request, in case the pool is empty, do not wait for a whole bulk allocation to complete. Instead, trigger an instant allocation of a single resource to reduce latency.

2022-07-29net/mlx5e: kTLS, Recycle objects of device-offloaded TLS TX connectionsTariq Toukan5-47/+199
The transport interface send (TIS) object is responsible for performing all transport related operations of the transmit side. The ConnectX HW uses a TIS object to save and access the TLS crypto information and state of an offloaded TX kTLS connection. Before this patch, we used to create a new TIS per connection and destroy it once it’s closed. Every create and destroy of a TIS is a FW command. Same applies for the private TLS context, where we used to dynamically allocate and free it per connection. Resources recycling reduce the impact of the allocation/free operations and helps speeding up the connection rate. In this feature we maintain a pool of TX objects and use it to recycle the resources instead of re-creating them per connection. A cached TIS popped from the pool is updated to serve the new connection via the fast-path HW interface, updating the tls static and progress params. This is a very fast operation, significantly faster than FW commands. On recycling, a WQE fence is required after the context params change. This guarantees that the data is sent after the context has been successfully updated in hardware, and that the context modification doesn't interfere with existing traffic.

2022-07-29net/tls: Multi-threaded calls to TX tls_dev_delTariq Toukan2-32/+33
Multiple TLS device-offloaded contexts can be added in parallel via concurrent calls to .tls_dev_add, while calls to .tls_dev_del are sequential in tls_device_gc_task. This is not a sustainable behavior. This creates a rate gap between add and del operations (addition rate outperforms the deletion rate). When running for enough time, the TLS device resources could get exhausted, failing to offload new connections. Replace the single-threaded garbage collector work with a per-context alternative, so they can be handled on several cores in parallel. Use a new dedicated destruct workqueue for this.

Hence, the cleanup of such contexts must be deferred and completed inside an async work. For all others, this is not necessary, as cleanup is atomic.

Eric indicates that restarting rcvtimeo on every wait may be fine. I thought that we should consider it cumulative, and made tls_rx_reader_lock() return the remaining timeo after acquiring the reader lock. tls_rx_rec_wait() gets its timeout passed in by value so it does not keep track of time previously spent. Make the lock waiting consistent with tls_rx_rec_wait() - don't keep track of time spent. Read the timeo fresh in tls_rx_rec_wait(). It's unclear to me why callers are supposed to cache the value.

That's being flagged by the libbpf CI system, which builds for ppc64le and the compiler sees a NULL pointer being passed in to a %s format string. With this change we add representations for two more architectures, for Power PC and Power PC 64, and also adjust the string format logic to handle NULL pointers gracefully, in an attempt to prevent similar issues with other architectures in the future.

Add red and green counters per meter instance. TC police action is implemented as a meter instance. The meter counters represent the police action notexceed/exceed counters. TC rules using the same meter instance will use the same counters.

2022-07-28ice: compress branches in ice_set_features()Maciej Fijalkowski1-21/+19
Instead of rather verbose comparison of current netdev->features bits vs the incoming ones from user, let us compress them by a helper features set that will be the result of netdev->features XOR features. This way, current, extensive branches: if (features & NETIF_F_BIT && !(netdev->features & NETIF_F_BIT)) set_feature(true); else if (!(features & NETIF_F_BIT) && netdev->features & NETIF_F_BIT) set_feature(false); can become: netdev_features_t changed = netdev->features ^ features; if (changed & NETIF_F_BIT) set_feature(!!(features & NETIF_F_BIT)); This is nothing new as currently several other drivers use this approach, which I find much more convenient.
