A number of mlxsw-specific QoS tests use manual QoS DCB management. As such, they need to make sure lldpad is not running, because it would override the configuration the test has applied using other tools. To that end, these selftests invoke the bail_on_lldpad() helper, which terminates the selftest if th lldpad is running. Some of these tests however first install the bash exit trap, which invokes a cleanup() at the test exit. If bail_on_lldpad() has terminated the script even before the setup part was run, the cleanup part will be very confused. Therefore make sure bail_on_lldpad() is invoked before the cleanup is registered. While there are still edge cases where the user terminates the script before the setup was fully done, this takes care of a common situation where the cleanup would be invoked in an inconsistent state.

Martin Habets says: ==================== sfc: Move Siena into a separate subdirectory The Siena NICs (SFN5000 and SFN6000 series) went EOL in November 2021. Most of these adapters have been remove from our test labs, and testing has been reduced to a minimum. This patch series creates a separate kernel module for the Siena architecture, analogous to what was done for Falcon some years ago. This reduces our maintenance for the sfc.ko module, and allows us to enhance the EF10 and EF100 drivers without the risk of breaking Siena NICs. After this series further enhancements are needed to differentiate the new kernel module from sfc.ko, and the Siena code can be removed from sfc.ko. Thes will be posted as a small follow-up series. The Siena module is not built by default, but can be enabled using Kconfig option SFC_SIENA. This will create module sfc-siena.ko. Patches Patch 1 disables the Siena code in the sfc.ko module. Patches 2-6 establish the code base for the Siena driver. Patches 7-12 ensure the allyesconfig build succeeds. Patch 13 adds the basic Siena module. I do not expect patch 2 through 5 to be reviewed, they are FYI only. No checkpatch issues were resolved as part of these, but they were fixed in the subsequent patches. Testing Various build tests were done such as allyesconfig, W=1 and sparse. The new sfc-siena.ko and sfc.ko modules were tested on a machine with both these NICs in them, and several tests were run on both drivers. Martin --- v3: - Fix build errors after rebase. v2: - Split up patch that copies existing files. - Only copy a subset of mcdi_pcol.h. - Use --find-copies-harder as suggested by Benjamin Poirier. - Merge several patches for the allyesconfig build into larger ones. ==================== Signed-off-by: -

Mat Martineau says: ==================== mptcp: Userspace path manager API Userspace path managers (PMs) make use of generic netlink MPTCP events and commands to control addition and removal of MPTCP subflows on an existing MPTCP connection. The path manager events have already been upstream for a while, and this patch series adds four netlink commands for userspace: * MPTCP_PM_CMD_ANNOUNCE: advertise an address that's available for additional subflow connections. * MPTCP_PM_CMD_REMOVE: revoke an advertisement * MPTCP_PM_CMD_SUBFLOW_CREATE: initiate a new subflow on an existing MPTCP connection * MPTCP_PM_CMD_SUBFLOW_DESTROY: close a subflow on an existing MPTCP connection Userspace path managers, such as mptcpd, can be more easily customized for different devices. The in-kernel path manager remains available to handle server use cases. Patches 1-3 update common path manager code (used by both in-kernel and userspace PMs) Patches 4, 6, and 8 implement the new generic netlink commands. Patches 5, 7, and 9-13 add self test support and test cases for the new path manager commands. ==================== Signed-off-by: -

This change updates the "pm_nl_ctl" testing sample with a "listen" option to bind a MPTCP listening socket to the provided addr+port. This option is exercised in testing subflow initiation scenarios in conjunction with userspace path managers where the MPTCP application does not hold an active listener to accept requests for new subflows.

This change adds to self-testing support for the MPTCP netlink interface by capturing various MPTCP netlink events (and all their metadata) associated with connections, subflows and address announcements.

This allows userspace to tell kernel to add a new subflow to an existing mptcp connection. Userspace provides the token to identify the mptcp-level connection that needs a change in active subflows and the local and remote addresses of the new or the to-be-removed subflow. MPTCP_PM_CMD_SUBFLOW_CREATE requires the following parameters: { token, { loc_id, family, loc_addr4 | loc_addr6 }, { family, rem_addr4 | rem_addr6, rem_port } MPTCP_PM_CMD_SUBFLOW_DESTROY requires the following parameters: { token, { family, loc_addr4 | loc_addr6, loc_port }, { family, rem_addr4 | rem_addr6, rem_port } Acked-by:Florian Westphal <fw@strlen.de> Signed-off-by:

Next patch will need to parse MPTCP_PM_ATTR_ADDR attributes and fill an mptcp_addr_info structure from a different genl command callback. To avoid copy-paste, split the existing function to a helper that does the common part and then call the helper from the (renamed)mptcp_pm_parse_entry function. Acked-by:

This change introduces a parallel path in the kernel for retrieving the local id, flags, if_index for an addr entry in the context of an MPTCP connection that's being managed by a userspace PM. The userspace and in-kernel PM modes deviate in their procedures for obtaining this information. Acked-by:

This change adds an internal function to store/retrieve local addrs announced by userspace PM implementations to/from its kernel context. The function addresses the requirements of three scenarios: 1) ADD_ADDR announcements (which require that a local id be provided), 2) retrieving the local id associated with an address, and also where one may need to be assigned, and 3) reissuance of ADD_ADDRs when there's a successful match of addr/id. The list of all stored local addr entries is held under the MPTCP sock structure. Memory for these entries is allocated from the sock option buffer, so the list of addrs is bounded by optmem_max. The list if not released via REMOVE_ADDR signals is ultimately freed when the sock is destructed. Acked-by:

Currently, all released FW versions support only two IPsec object modifiers, and modify_field_select get and set same value with proper bits. However, it is not future compatible, as new FW can have more modifiers and "default" will cause to overwrite not-changed fields. Fix it by setting explicitly fields that need to be overwritten.

The mlx5 IPsec code has logical separation between code that operates with XFRM objects (ipsec.c), HW objects (ipsec_offload.c), flow steering logic (ipsec_fs.c) and data path (ipsec_rxtx.c). Such separation makes sense for C-files, but isn't needed at all for H-files as they are included in batch anyway. Reviewed-by:

mlx5 IPsec code updated ESN through workqueue with allocation calls in the data path, which can be saved easily if the work is created during XFRM state initialization routine. The locking used later in the work didn't protect from anything because change of HW context is possible during XFRM state add or delete only, which can cancel work and make sure that it is not running.

The XFRM code performs fallback to software IPsec if .xdo_dev_state_add() returns -EOPNOTSUPP. This is what mlx5 did very deep in its stack trace, despite have all the knowledge that IPsec is not going to work in very early stage. This is achieved by making sure that priv->ipsec pointer is valid for fully working and supported hardware crypto IPsec engine. In case, the hardware IPsec is not supported, the XFRM code will set NULL to xso->dev and it will prevent from calls to various .xdo_dev_state_*() callbacks. Reviewed-by:

Most drivers should not have to worry about selecting the right weight for their NAPI instances and pass NAPI_POLL_WEIGHT. It'd be best if we didn't require the argument at all and selected the default internally. This change prepares the ground for such reshuffling, allowing for a smooth transition. The following API should remain after the next release cycle: netif_napi_add() netif_napi_add_weight() netif_napi_add_tx() netif_napi_add_tx_weight() Where the _weight() variants take an explicit weight argument. I opted for a _weight() suffix rather than a __ prefix, because we use __ in places to mean that caller needs to also issue a synchronize_net() call. Signed-off-by:
