2025-03-11wifi: iwlwifi: mvm: Fix bit size calculation in iwl_dbgfs_tas_get_status_readPagadala Yesu Anjaneyulu
Corrected the bit size calculation in the for_each_set_bit macro in the iwl_dbgfs_tas_get_status_read(). The previous implementation used sizeof(dyn_status), which only accounts for the number of bytes. This has been updated to TAS_DYNA_STATUS_MAX to ensure the loop iterates over the correct number of valid bits in dyn_status.

2025-03-11wifi: iwlwifi: w/a FW SMPS mode selectionDaniel Gabay
The FW is now responsible of determining the SMPS mode. If the user disabled power save in a certain vif, we send the vif-level power command to clear out the POWER_FLAGS_POWER_MANAGEMENT_ENA_MSK bit for that vif. But erroneously, the FW checks DEVICE_POWER_FLAGS_POWER_SAVE_ENA_MSK in the device-level command to determine the SMPS mode. To W/A this, send also the device-level command when the power save of a vif changes, and disable power save if there is any vif that has power save disabled.

2025-03-11wifi: iwlwifi: fix debug actions orderJohannes Berg
The order of actions taken for debug was implemented incorrectly. Now we implemented the dump split and do the FW reset only in the middle of the dump (rather than the FW killing itself on error.) As a result, some of the actions taken when applying the config will now crash the device, so we need to fix the order.

2025-03-10Merge branch 'mptcp-pm-code-reorganisation'Jakub Kicinski
Matthieu Baerts says: ==================== mptcp: pm: code reorganisation Before this series, the PM code was dispersed in different places: - pm.c had common code for all PMs. - pm_netlink.c was initially only about the in-kernel PM, but ended up also getting exported common helpers, callbacks used by the different PMs, NL events for PM userspace daemon, etc. quite confusing. - pm_userspace.c had userspace PM only code, but it was using "specific" in-kernel PM helpers according to their names. To clarify the code, a reorganisation is suggested here, only by moving code around, and small helper renaming to avoid confusions: - pm_netlink.c now only contains common PM generic Netlink code: - PM events: this code was already there - shared helpers around Netlink code that were already there as well - shared Netlink commands code from pm.c - pm_kernel.c now contains only code that is specific to the in-kernel PM. Now all functions are either called from: - pm.c: events coming from the core, when this PM is being used - pm_netlink.c: for shared Netlink commands - mptcp_pm_gen.c: for Netlink commands specific to the in-kernel PM - sockopt.c: for the exported counters per netns - pm.c got many code from pm_netlink.c: - helpers used from both PMs and not linked to Netlink - callbacks used by different PMs, e.g. ADD_ADDR management - some helpers have been renamed to remove the '_nl' prefix, and some have been marked as 'static'. - protocol.h has been updated accordingly: - some helpers no longer need to be exported - new ones needed to be exported: they have been prefixed if needed. The code around the PM is now less confusing, which should help for the maintenance in the long term, and the introduction of a PM Ops. This will certainly impact future backports, but because other cleanups have already done recently, and more are coming to ease the addition of a new path-manager controlled with BPF (struct_ops), doing that now seems to be a good time. Also, many issues around the PM have been fixed a few months ago while increasing the code coverage in the selftests, so such big reorganisation can be done with more confidence now. Note that checkpatch, when used with --max-line-length=80, will complain about lines being over the 80 limits, but these warnings were already there before moving the code around. Also, patch 1 is not directly related to the code reorganisation, but it was a remaining cleanup that we didn't upstream before, because it was conflicting with another patch that has been sent for inclusion to the net tree. ==================== Link: https://patch.msgid.link/20250307-net-next-mptcp-pm-reorg-v1-0-abef20ada03b@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

To make it clear what actions are in-kernel PM specific and which ones are not and done for all PMs, e.g. sending ADD_ADDR and close associated subflows when a RM_ADDR is received. The behavioural is changed a bit: MPTCP_PM_ADD_ADDR_RECEIVED is now treated after MPTCP_PM_ADD_ADDR_SEND_ACK and MPTCP_PM_RM_ADDR_RECEIVED, but that should not change anything in practice.

2025-03-10mptcp: pm: avoid calling PM specific code from coreMatthieu Baerts (NGI0)
When destroying an MPTCP socket, some userspace PM specific code was called from mptcp_destroy_common() in protocol.c. That feels wrong, and it is the only case. Instead, the core now calls mptcp_pm_destroy() from pm.c which is now in charge of cleaning the announced addresses list, and ask the different PMs to do extra cleaning if needed, e.g. the userspace PM, if used, will clean the local addresses list. While at it, the userspace PM specific helper has been prefixed with 'mptcp_userspace_pm_' like the other ones. No behavioural changes intended.
