Commit fb3dda82fd38 ("net: airoha: Move airoha_eth driver in a dedicated folder") accidentally added the line: source "drivers/net/ethernet/mellanox/Kconfig" in drivers/net/ethernet/Kconfig, so that this line is duplicated in that file.

Commit fb3dda82fd38 ("net: airoha: Move airoha_eth driver in a dedicated folder") moves the driver to drivers/net/ethernet/airoha/, but misses to adjust the AIROHA ETHERNET DRIVER section in MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Adjust the file entry to the dedicated folder for this driver.

Not everything is sensitive, and some info can be exported to all users in order to ease the debugging from the userspace side without requiring additional capabilities. First, the ULP name can be easily exported. Then more depending on each layer: - On kTLS side, it looks like everything can be exported to all users: version, cipher type, tx/rx user config type, plus some flags. - On MPTCP side, everything but the sequence numbers are exported to all non net admin users, similar to TCP. ==================== Link: https://patch.msgid.link/20250306-net-next-tcp-ulp-diag-net-admin-v1-0-06afdd860fc9@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-03-07tcp: ulp: diag: more info without CAP_NET_ADMINMatthieu Baerts (NGI0)
When introduced in commit 61723b393292 ("tcp: ulp: add functions to dump ulp-specific information"), the whole ULP diag info has been exported only if the requester had CAP_NET_ADMIN. It looks like not everything is sensitive, and some info can be exported to all users in order to ease the debugging from the userspace side without requiring additional capabilities. Each layer should then decide what can be exposed to everybody. The 'net_admin' boolean is then passed to the different layers. On kTLS side, it looks like there is nothing sensitive there: version, cipher type, tx/rx user config type, plus some flags. So, only some metadata about the configuration, no cryptographic info like keys, etc. Then, everything can be exported to all users. On MPTCP side, that's different. The MPTCP-related sequence numbers per subflow should certainly not be exposed to everybody. For example, the DSS mapping and ssn_offset would give all users on the system access to narrow ranges of values for the subflow TCP sequence numbers and MPTCP-level DSNs, and then ease packet injection. The TCP diag interface doesn't expose the TCP sequence numbers for TCP sockets, so best to do the same here. The rest -- token, IDs, flags -- can be exported to everybody.

Since its introduction in commit 61723b393292 ("tcp: ulp: add functions to dump ulp-specific information"), the ULP diag info have been exported only if the requester had CAP_NET_ADMIN. At least the ULP name can be exported without CAP_NET_ADMIN. This will already help identifying which layer is being used, e.g. which TCP connections are in fact MPTCP subflow.

Support ethtool -g / -G. Leverage the code added for -l / -L to alloc / stop / start / free. Check parameters against HW min/max but also our own min/max. Min HW queue is 16 entries, we can't deal with TWQs that small because of the queue waking logic. Add similar contraint on RCQ for symmetry. We need 3 sizes on Rx, as the NIC does header-data split two separate buffer pools: (1) head page ring - how many empty pages we post for headers (2) payload page ring - how many empty pages we post for payloads (3) completion ring - where NIC produces the Rx descriptors Acked-by: Joe Damato <jdamato@fastly.com> Link: https://patch.msgid.link/20250306145150.1757263-4-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Patches 1-3 by Shahar introduce support for configuring lanes alongside speed when autonegotiation is disabled. The combination of speed and the number of lanes corresponds to a specific link mode (in the extended mask typically used in newer hardware), allowing the user to select a precise link mode when autonegotiation is off, instead of just choosing the speed. Patch 4 by Amir extends the multi-port LAG support.

2025-03-06net/mlx5e: Properly match IPsec subnet addressesLeon Romanovsky
Existing match criteria didn't allow to match whole subnet and only by specific addresses only. This caused to tunnel mode do not forward such traffic through relevant SA. In tunnel mode, policies look like this: src 192.169.0.0/16 dst 192.169.0.0/16 dir out priority 383615 ptype main tmpl src 192.169.101.2 dst 192.169.101.1 proto esp spi 0xc5141c18 reqid 1 mode tunnel crypto offload parameters: dev eth2 mode packet In this case, the XFRM core code handled all subnet calculations and forwarded network address to the drivers e.g. 192.169.0.0. For mlx5 devices, there is a need to set relevant prefix e.g. 0xFFFF00 to perform flow steering match operation.

2025-03-06net/mlx5e: Enable lanes configuration when auto-negotiation is offShahar Shitrit
Currently, when auto-negotiation is disabled, the driver retrieves the speed and converts it into all link modes that correspond to that speed. With this patch, we add the ability to set the number of lanes, so that the combination of speed and lanes corresponds to exactly one specific link mode for the extended bit map. For the legacy bit map the driver sets all link modes correspond to speed and lanes. This change provides users with the option to set a specific link mode, rather than enabling all link modes associated with a given speed when auto-negotiation is off.

2025-03-06net/mlx5: Refactor link speed handling with mlx5_link_info structShahar Shitrit
Introduce struct mlx5_link_info with a speed field and change the types of mlx5e_link_speed and mlx5e_ext_link_speed from arrays of u32 to arrays of struct mlx5_link_info. These arrays are renamed to mlx5e_link_info and mlx5e_ext_link_info, respectively. This change prepares for a future patch that will introduce a lanes field in struct mlx5_link_info and add lanes mapping alongside the speed for each link mode in the two arrays. Additionally, rename function mlx5_port_speed2linkmodes() to mlx5_port_info2linkmodes() and function mlx5_port_ptys2speed() to mlx5_port_ptys2info() and update the speed parameter/return type to struct mlx5_link_info, in preparation for the upcoming patch where these functions will also utilize the lanes field.

The port header is a general file under include, yet it contains declarations for functions that are either not exported or exported but not used outside the mlx5_core driver. To enhance code organization, we move these declarations to mlx5_core.h, where they are more appropriately scoped. This refactor removes unnecessary exported symbols and prevents unexported functions from being inadvertently referenced outside of the mlx5_core driver.

2025-03-06net: ti: icss-iep: Add phase offset configuration for perout signalMeghana Malladi
icss_iep_perout_enable_hw() is a common function for generating both pps and perout signals. When enabling pps, the application needs to only pass enable/disable argument, whereas for perout it supports different flags to configure the signal. In case the app passes a valid phase offset value, the signal should start toggling after that phase offset, else start immediately or as soon as possible. ICSS_IEP_SYNC_START_REG register take number of clock cycles to wait before starting the signal after activation time. Set appropriate value to this register to support phase offset.

icss_iep_perout_enable_hw() is a common function for generating both pps and perout signals. When enabling pps, the application needs to only pass enable/disable argument, whereas for perout it supports different flags to configure the signal. But icss_iep_perout_enable_hw() function is missing to hook the configuration params passed by the app, causing perout to behave same a pps (except being able to configure the period). As duty cycle is also one feature which can configured for perout, incorporate this in the function to get the expected signal.
