Daniel Machon says: ==================== net: Add QoS offload support for sparx5 This patch series adds support for offloading QoS features with the tc command suite, to the sparx5 switch. The new offloadable QoS features introduced in this patch series are: - tc-mqprio for mapping traffic class to hardware queue. Queues are by default mapped 1:1 in hardware, as such the mqprio qdisc is used as an attachment point for qdiscs tbf and ets. $ tc qdisc add dev eth0 root handle 1:0 mqprio - tc-tbf for setting up shaping on scheduler elements of the HSCH (Hierarchical Scheduler) block. Shaping on either port output or queue output is supported. Port shaper: $ tc qdisc add dev eth0 root handle 1:0 tbf rate \ 10000000 burst 8192 limit 1m Queue shaper: $ tc qdisc replace dev eth0 parent 1:5 handle 2:0 tbf \ rate 10000000 burst 8192 limit 1m - tc-ets for setting up strict and or bandwidth-sharing bands on one through eight priority queues. Configure a mix of strict and bw-sharing bands: $ tc qdisc add dev eth0 handle 1: root ets bands 8 strict 5 \ quanta 1000 1000 1000 priomap 7 6 5 4 3 2 1 0 Patch #1 Sets up the tc hook. Patch #2 Adds support for offloading the tc-mqprio qdisc. Patch #3 Adds support for offloading the tc-tbf qdisc. Patch #4 Adds support for offloading the tc-ets qdisc. Patch #5 Updates the maintainers of the sparx5 driver. ======================================================================== v1: https://lore.kernel.org/netdev/20220919120215.3815696-1-daniel.machon@microchip.com/ v1 -> v2: - Fix compiler warning in patch #2 - Fix comment style in patch #4 ==================== Signed-off-by:David S.

Add support for offloading ets qdisc to sparx5 switch. The ets qdisc makes it possible to configure a mix og strict and bandwidth-sharing bands. The ets qdisc must be attached as a root qdisc. Signed-off-by:

Add support for offloading tbf qdisc to sparx5 qdisc. The tbf qdisc makes it possible to attach a shaper on traffic egressing from a port or a queue. Per-port tbf qdiscs are attached as a root qdisc directly and queue tbf qdiscs are attached to one of the classes of a parent qdisc (such as mqprio). Signed-off-by:

Add support for offloading mqprio qdisc to sparx5 switch. The offloaded mqprio qdisc currently does nothing by itself, but serves as an attachment point for other qdiscs (tbf, ets etc.) Signed-off-by:

The driver_data will be set to NULL in device_unbind_cleanup() after calling ->remove(), so all set_drvdata(NULL) functions in ->remove() is redundant, they can be removed.

Check the return value of nla_nest_start(). When starting the entry level nested attributes, if the tailroom of socket buffer is insufficient to store the attribute header and payload, the return value will be NULL. There is, however, no real bug here since if the skb is full nla_put_be16() will fail as well and we'll error out. Signed-off-by:

Saeed Mahameed says: ==================== mlx5 MACSec Extended packet number and replay window offload This is a follow up series to the previously submitted mlx5 MACsec offload [1] earlier this release cycle. In this series we add the support for MACsec Extended packet number and replay window offloads. First patch is a simple modification (code movements) to the core macsec code to allow exposing the EPN related user properties to the offloading device driver. The rest of the patches are mlx5 specific, we start off with fixing some trivial issues with mlx5 MACsec code, and a simple refactoring to allow additional functionality in mlx5 macsec to support EPN and window replay offloads. A) Expose mkey creation functionality to MACsec B) Expose ASO object to MACsec, to allow advanced steering operations, ASO objects are used to modify MACsec steering objects in fastpath. 1) Support MACsec offload extended packet number (EPN) MACsec EPN splits the packet number (PN) into two 32-bits fields, epn_lsb (32 least significant bits (LSBs) of PN) and epn_msb (32 most significant bits (MSBs) of PN). Epn_msb bits are managed by SW and for that HW is required to send an object change event of type EPN event notifying the SW to update the epn_msb in addition, once epn_msb is updated SW update HW with the new epn_msb value for HW to perform replay protection. To prevent HW from stopping while handling the event, SW manages another bit for HW called epn_overlap, HW uses the latter to get an indication regarding how to read the epn_msb value correctly while still receiving packets. Add epn event handling that updates the epn_overlap and epn_msb for every 2^31 packets according to the following logic: if epn_lsb crosses 2^31 (half sequence number wraparound) upon HW relevant event, SW updates the esn_overlap value to OLD (value = 1). When the epn_lsb crosses 2^32 (full sequence number wraparound) upon HW relevant event, SW updates the esn_overlap to NEW (value = 0) and increment the esn_msb. When using MACsec EPN a salt and short secure channel id (ssci) needs to be provided by the user, when offloading EPN need to pass this salt and ssci to the HW to be used in the initial vector (IV) calculations. 2) Support MACsec offload replay window Support setting replay window size for MACsec offload. Currently supported window size of 32, 64, 128 and 256 bit. Other values will be returned as invalid parameter.

Add support for ASO work queue entry (WQE) data to allow reading data upon querying the ASO work queue (WQ). Register user mode memory registration (UMR) upon ASO WQ init, de-register UMR upon ASO WQ cleanup. MACsec uses UMR to determine the cause of the event triggered by the HW since different scenarios could trigger the same event.

Currently when creating MACsec object, next_pn which represents the initial packet number (PN) is considered only in TX flow. The above causes mismatch between TX and RX initial PN which is reflected in packet drops. Fix by considering next_pn in RX flow too.

Currently macsec invokes HW offload path before reading extended packet number (EPN) related user properties i.e. salt and short secure channel identifier (ssci), hence preventing macsec EPN HW offload. Expose those by moving macsec EPN properties reading prior to HW offload path. Signed-off-by:
