Ido Schimmel says: ==================== mlxsw: Offload TC action pedit munge dsfield Petr says: The Spectrum switches allow packet prioritization based on DSCP on ingress, and update of DSCP on egress. This is configured through the DCB APP rules. For some use cases, assigning a custom DSCP value based on an ACL match is a better tool. To that end, offload FLOW_ACTION_MANGLE to permit changing of dsfield as a whole, or DSCP and ECN values in isolation. After fixing a commentary nit in patch #1, and mlxsw naming in patch #2, patches #3 and #4 add the offload to mlxsw. Patch #5 adds a forwarding selftest for pedit dsfield, applicable to SW as well as HW datapaths. Patch #6 adds a mlxsw-specific test to verify DSCP rewrite due to DCB APP rules is not performed on pedited packets. The tests only cover IPv4 dsfield setting. We have tests for IPv6 as well, but would like to postpone their contribution until the corresponding iproute patches have been accepted. ==================== Signed-off-by:

In the commit f73b1281 ("tipc: improve throughput between nodes in netns"), we're missing a check to handle TIPC_DIRECT_MSG type, it's still using old sending mechanism for this message type. So, throughput improvement is not significant as expected. Besides that, when sending a large message with that type, we're also handle wrong receiving queue, it should be enqueued in socket receiving instead of multicast messages. Fix this by adding the missing case for TIPC_DIRECT_MSG. Fixes: f73b1281 ("tipc: improve throughput between nodes in netns") Reported-by:

Currently eswitch mode change is occurring from 2 different execution contexts as below. 1. sriov sysfs enable/disable 2. devlink eswitch set commands Both of them need to access eswitch related data structures in synchronized manner. Without any synchronization below race condition exist. SR-IOV enable/disable with devlink eswitch mode change: cpu-0 cpu-1 ----- ----- mlx5_device_disable_sriov() mlx5_devlink_eswitch_mode_set() mlx5_eswitch_disable() esw_offloads_stop() esw_offloads_disable() mlx5_eswitch_disable() esw_offloads_disable() Hence, they are synchronized using a new mode_lock. eswitch's state_lock is not used as it can lead to a deadlock scenario below and state_lock is only for vport and fdb exclusive access. ip link set vf <param> netlink rcv_msg() - Lock A rtnl_lock vfinfo() esw->state_lock() - Lock B devlink eswitch_set devlink_mutex esw->state_lock() - Lock B attach_netdev() register_netdev() rtnl_lock - Lock A Alternatives considered: 1. Acquiring rtnl lock before taking esw->state_lock to follow similar locking sequence as ip link flow during eswitch mode set. rtnl lock is not good idea for two reasons. (a) Holding rtnl lock for several hundred device commands is not good idea. (b) It leads to below and more similar deadlocks. devlink eswitch_set devlink_mutex rtnl_lock - Lock A esw->state_lock() - Lock B eswitch_disable() reload() ib_register_device() ib_cache_setup_one() rtnl_lock() 2. Exporting devlink lock may lead to undesired use of it in vendor driver(s) in future. 3. Unloading representors outside of the mode_lock requires serialization with other process trying to enable the eswitch. 4. Differing the representors life cycle to a different workqueue requires synchronization with func_change_handler workqueue. Reviewed-by:

devlink_nl_cmd_eswitch_set_doit() doesn't hold devlink->lock mutex while invoking driver callback. This is likely due to eswitch mode setting involves adding/remove devlink ports, health reporters or other devlink objects for a devlink device. So it is driver responsiblity to ensure thread safe eswitch state transition happening via either sriov legacy enablement or via devlink eswitch set callback. Therefore, get() callback should also be invoked without holding devlink->lock mutex. Vendor driver can use same internal lock which it uses during eswitch mode set() callback. This makes get() and set() implimentation symmetric in devlink core and in vendor drivers. Hence, remove holding devlink->lock mutex during eswitch get() callback. Failing to do so results into below deadlock scenario when mlx5_core driver is improved to handle eswitch mode set critical section invoked by devlink and sriov sysfs interface in subsequent patch. devlink_nl_cmd_eswitch_set_doit() mlx5_eswitch_mode_set() mutex_lock(esw->mode_lock) <- Lock A [...] register_devlink_port() mutex_lock(&devlink->lock); <- lock B mutex_lock(&devlink->lock); <- lock B devlink_nl_cmd_eswitch_get_doit() mlx5_eswitch_mode_get() mutex_lock(esw->mode_lock) <- Lock A In subsequent patch, mlx5_core driver uses its internal lock during get() and set() eswitch callbacks. Other drivers have been inspected which returns either constant during get operations or reads the value from already allocated structure. Hence it is safe to remove the lock in get( ) callback and let vendor driver handle it. Reviewed-by:

Group version is used when modifying a rule is allowed (FLOW_ACT_NO_APPEND is clear) to detect a case where the rule was found but while the groups where unlocked a new FTE was added. In this case, the added FTE could be one with identical match value so we need to attempt again with group lock held. Change the code so version is retrieved only when FLOW_ACT_NO_APPEND is cleared. As result, later compare can also be avoided if FLOW_ACT_NO_APPEND is cleared. Also improve comments text. Signed-off-by:

When adding a rule to a flow group we need increment the version of the group. Current code fails to do that and as a result, when trying to add a rule, we will fail to discover a case where an FTE with the same match value was added while we scanned the groups of the same match criteria, thus we may try to add an FTE that was already added.

Since IQD devices complete (most of) their transmissions synchronously, they don't offer TX completion IRQs and have no HW coalescing controls. But we can fake the easy parts in SW, and give the user some control wrt to how often the TX NAPI code should be triggered to process the TX completions. Having per-queue controls can in particular help the dedicated mcast queue, as it likely benefits from different fine-tuning than what the ucast queues need.
