net/mlx5: Refactor LAG peer device lookout bus logic to mlx5 devcom

2023-10-14T17:16:30Z

LAG peer device lookout bus logic required the usage of global lock, mlx5_intf_mutex. As part of the effort to remove this global lock, refactor LAG peer device lookout to use mlx5 devcom layer.

net/mlx5: Parallelize vhca event handling

2023-10-14T17:16:29Z

At present, mlx5 driver have a general purpose event handler which not only handles vhca event but also many other events. This incurs a huge bottleneck because the event handler is implemented by single threaded workqueue and all events are forced to be handled in serial manner even though application tries to create multiple SFs simultaneously. Introduce a dedicated vhca event handler which manages SFs parallel creation.

RDMA/mlx5: Send events from IB driver about device affiliation state

2023-10-02T08:20:59Z

Send blocking events from IB driver whenever the device is done being affiliated or if it is removed from an affiliation. This is useful since now the EN driver can register to those event and know when a device is affiliated or not.

net/mlx5: Provide an interface to block change of IPsec capabilities

2023-08-28T00:08:45Z

mlx5 HW can't perform IPsec offload operation simultaneously both on PF and VFs at the same time. While the previous patches added devlink knobs to change IPsec capabilities dynamically, there is a need to add a logic to block such IPsec capabilities for the cases when IPsec is already configured.

Leon Romanovsky says: ==================== mlx5 MACsec RoCEv2 support From Patrisious: This series extends previously added MACsec offload support to cover RoCE traffic either. In order to achieve that, we need configure MACsec with offload between the two endpoints, like below: REMOTE_MAC=10:70:fd:43:71:c0 * ip addr add 1.1.1.1/16 dev eth2 * ip link set dev eth2 up * ip link add link eth2 macsec0 type macsec encrypt on * ip macsec offload macsec0 mac * ip macsec add macsec0 tx sa 0 pn 1 on key 00 dffafc8d7b9a43d5b9a3dfbbf6a30c16 * ip macsec add macsec0 rx port 1 address $REMOTE_MAC * ip macsec add macsec0 rx port 1 address $REMOTE_MAC sa 0 pn 1 on key 01 ead3664f508eb06c40ac7104cdae4ce5 * ip addr add 10.1.0.1/16 dev macsec0 * ip link set dev macsec0 up And in a similar manner on the other machine, while noting the keys order would be reversed and the MAC address of the other machine. RDMA traffic is separated through relevant GID entries and in case of IP ambiguity issue - meaning we have a physical GIDs and a MACsec GIDs with the same IP/GID, we disable our physical GID in order to force the user to only use the MACsec GID. v0: https://lore.kernel.org/netdev/20230813064703.574082-1-leon@kernel.org/ * 'mlx5-next' of https://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux: RDMA/mlx5: Handles RoCE MACsec steering rules addition and deletion net/mlx5: Add RoCE MACsec steering infrastructure in core net/mlx5: Configure MACsec steering for ingress RoCEv2 traffic net/mlx5: Configure MACsec steering for egress RoCEv2 traffic IB/core: Reorder GID delete code for RoCE net/mlx5: Add MACsec priorities in RDMA namespaces RDMA/mlx5: Implement MACsec gid addition and deletion net/mlx5: Maintain fs_id xarray per MACsec device inside macsec steering net/mlx5: Remove netdevice from MACsec steering net/mlx5e: Move MACsec flow steering and statistics database from ethernet to core net/mlx5e: Rename MACsec flow steering functions/parameters to suit core naming style net/mlx5: Remove dependency of macsec flow steering on ethernet net/mlx5e: Move MACsec flow steering operations to be used as core library macsec: add functions to get macsec real netdevice and check offload ==================== Link: https://lore.kernel.org/r/20230821073833.59042-1-leon@kernel.org Signed-off-by: Jakub Kicinski

RDMA/mlx5: Handles RoCE MACsec steering rules addition and deletion

2023-08-20T09:35:24Z

Add RoCE MACsec rules when a gid is added for the MACsec netdevice and handle their cleanup when the gid is removed or the MACsec SA is deleted. Also support alias IP for the MACsec device, as long as we don't have more ips than what the gid table can hold. In addition handle the case where a gid is added but there are still no SAs added for the MACsec device, so the rules are added later on when the SAs are added.

net/mlx5: Add RoCE MACsec steering infrastructure in core

2023-08-20T09:35:24Z

Adds all the core steering helper functions that are needed in order to setup RoCE steering rules which includes both the RX and TX rules addition and deletion. As well as exporting the function to be ready to use from the IB driver where we expose functions to allow deletion of all rules, which is needed when a GID is deleted, or a deletion of a specific rule when an SA is deleted, and a similar manner for the rules addition. These functions are used in a later patch by IB driver to trigger the rules addition/deletion when needed. Signed-off-by: Patrisious Haddad Signed-off-by: Leon Romanovsky
