bus: fsl-mc: Annotate fsl_mc_io.portal_virt_addr with __counted_by_ptr

2026-10-09T08:15:19Z

The GCC and Clang compilers provide the __counted_by_ptr attribute, which is used by KASAN and compiler bounds-checking to detect out-of-bounds accesses to pointer fields. In "struct fsl_mc_io", the "portal_virt_addr" pointer points to the MC command portal virtual address. The size of this allocated portal in bytes is tracked by the "portal_size" field within the same structure. Annotate the "portal_virt_addr" pointer field with "__counted_by_ptr(portal_size)" to enable compiler bounds-checking and harden against potential out-of-bounds accesses.

Pull networking updates from Jakub Kicinski: "One of the 'small improvements all over the place' releases for us. It's hard to draw any direct comparisons because summer vacations disrupted our patch processing (and presumably - generation) quite a bit. Quick and dirty count suggests we (Paolo and I) merged a very similar number of net (632) and net-next (648) patches. This is not telling the full story either because 1/3 to 1/2 of the net-next patches also *seem* like AI-driven low priority fixes, cleanups and clarifications. We are completely overwhelmed, of course. The glimmer of hope is that we secured sufficient LLM budget and access (thank you Meta!) to run reviews with multiple frontier models on each patch. This eliminates some hallucinations. That said, in terms of review, the LLMs can only do so much. The sad truth is that our APIs (especially for rare events like PCIe errors, timeouts etc) have always been racy, and now LLMs don't let us ignore that. I expect our direction for the next release will be to tweak the reviews a little bit more, but start shifting focus to letting the LLMs take care of the busy work - managing patchwork, automating common process complaints, editing commit messages, and maybe applying patches which already got "reviewed-by" tags from people we trust...

soc: fsl: guts: implement the RCW override procedure

2026-08-07T04:54:23Z

Add support for the RCW override procedure which enables runtime reconfiguration of the protocol running on a SerDes lane. The procedure is done through the DCFG DCSR space which now can be defined as the second memory region of the guts DT node. Support is added on the following SoCs: LS1046A, LS1088A, LS2088A. The procedure is exported to the "client" driver - the Lynx10G SerDes PHY driver - through the following functions: - fsl_guts_lane_validate() used to validate that changing the protocol on a specific lane is supported. - fsl_guts_lane_set_mode() which can be used to request the RCW procedure be executed for a specific lane. Since the RCW override procedure is different depending on the SoC, the private fsl_soc_data structure is updated with two new per SoC callbacks (.serdes_get_rcw_override() and .serdes_init_rcwcr()) which get used from the generic fsl_guts_lane_set_mode() function. These two callbacks hide all the SoC specific register offsets, masks and values so that the _set_mode() procedure is straightforward.

net: enetc: improve MAFT entry management with bitmap tracking

2026-07-27T23:31:53Z

Replace the counter-based MAFT entry tracking (num_mfe/mac_filter_num) with a bitmap (maft_eid_bitmap) stored in struct ntmp_user, which is a more appropriate place for NTMP resource management. The bitmap approach brings two improvements. First, the entry deletion in enetc4_pf_clear_maft_entries() now checks the return value of ntmp_maft_delete_entry() and only clears the corresponding bit on success, keeping hardware and software state in sync. Previously, the counter was reset unconditionally regardless of whether the hardware deletion actually succeeded. Second, entry allocation in enetc4_pf_add_maft_entries() uses ntmp_lookup_free_eid() to find available IDs dynamically, with an upfront capacity check via bitmap_weight() to avoid partial failures. The MAFT entry count is moved into ntmp_user.maft_num_entries and initialized once during enetc4_init_ntmp_user(). Helper functions enetc4_ntmp_bitmap_init() and enetc4_ntmp_bitmap_free() manage the bitmap lifetime. The debugfs show function is updated accordingly to iterate over set bits under rtnl_lock().

is included in a many files: $ git grep '' ef0c9f75a195 | wc -l 1598 ; some of them are widely used headers. To stop mixing up different and unrelated driver( type)s let the subsystem headers only use the subset of the recently split that are relevant for them. The fallout (I hope) is addressed in the previous commits that handle sources relying on e.g. pulling in the full legacy header and thus providing pci_device_id.

net: dsa: netc: add VLAN filter table and egress treatment management

2026-06-15T21:32:06Z

Implement the DSA .port_vlan_add and .port_vlan_del operations to enable VLAN-aware bridge offloading on the NETC switch. VLAN membership is maintained in the VLAN Filter Table (VFT). Adding the first port to a VLAN creates a new VFT entry with hardware MAC learning and flood-on-miss forwarding; subsequent ports update the existing entry's membership bitmap. Removing the last port deletes the entry. Egress tagging is handled through the Egress Treatment Table (ETT). Each VLAN is allocated a group of ETT entries, one per available port. Ports are assigned a sequential ett_offset during initialisation, used to address each port's entry within the group. Untagged ports configure the ETT to strip the outer VLAN tag; tagged ports pass frames through unmodified. Each ETT group is optionally paired with an Egress Counter Table (ECT) group for per-port frame counting, allocated on a best-effort basis. When the egress rule of an ETT entry changes, the counter of the corresponding ECT entry will be recounted to track the number of frames that match the new egress rule. A software shadow list serialised by vft_lock tracks active VLAN state across both port membership and egress tagging. VID 0 is used for single port mode and is ignored by both callbacks.
