Currently, the list which stores the MDB entries for a given bridge instance is called 'mids_list'. This name is not accurate as a MID entry stores a bitmap of ports to which a packet needs to be replicated and a MDB entry stores the mapping from {MAC, FID} to PGT index (MID) Rename it to 'mdb_list'.

Currently the structure which represents MDB entry is called 'struct mlxsw_sp_mid'. This name is not accurate as a MID entry stores a bitmap of ports to which a packet needs to be replicated and a MDB entry stores the mapping from {MAC, FID} to PGT index (MID). Rename the structure to 'struct mlxsw_sp_mdb_entry'. The structure 'mlxsw_sp_mid' is defined as part of spectrum.h. The only file which uses it is spectrum_switchdev.c, so there is no reason to expose it to other files. Move the definition to spectrum_switchdev.c. Signed-off-by: -

FID code reserves about 15K entries in PGT table for flooding. These entries are just allocated and are not used yet because the code that uses them is skipped now. The next patches will convert MDB code to use PGT APIs. The allocation of indexes for multicast is done after FID code reserves 15K entries. Currently, legacy bridge model is used and firmware manages PGT table. That means that the indexes which are allocated using PGT API are too high when legacy bridge model is used. To not exceed firmware limitation for MDB entries, add an API that returns the correct 'mid_index', based on bridge model. For legacy model, subtract the number of flood entries from PGT index. Use it to write the correct MID to SMID register. This API will be used also from MDB code in the next patches. PGT should not be aware of MDB and FID different usage, this API is temporary and will be removed once unified bridge model will be used. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Unified bridge conversion - part 4/6 This is the fourth part of the conversion of mlxsw to the unified bridge model. Unlike previous parts that prepared mlxsw for the conversion, this part actually starts the conversion. It focuses on flooding configuration and converts mlxsw to the more "raw" APIs of the unified bridge model. The patches configure the different stages of the flooding pipeline in Spectrum that looks as follows (at a high-level): +------------+ +----------+ +-------+ {FID, | | {Packet type, | | | | MID DMAC} | FDB lookup | Bridge type} | SFGC | MID base | | Index +--------> (miss) +----------------> register +-----------> Adder +-------> | | | | | | | | | | | | +------------+ +----+-----+ +---^---+ | | Table | | type | | Offset | +-------+ | | | | | | | | | +----->+ Mux +------+ | | | | +-^---^-+ | | FID| |FID | |offset + + The multicast identifier (MID) index is used as an index to the port group table (PGT) that contains a bitmap of ports via which a packet needs to be replicated. From the PGT table, the packet continues to the multicast port egress (MPE) table that determines the packet's egress VLAN. This is a two-dimensional table that is indexed by port and switch multicast port to egress (SMPE) index. The latter can be thought of as a FID. Without it, all the packets replicated via a certain port would get the same VLAN, regardless of the bridge domain (FID). Logically, these two steps look as follows: PGT table MPE table +-----------------------+ +---------------+ | | {Local port, | | Egress MID index | Local ports bitmap #1 | SMPE index} | | VID +------------> ... +---------------> +--------> | Local ports bitmap #N | | | | | SMPE | | +-----------------------+ +---------------+ Local port Patchset overview: Patch #1 adds a variable to guard against mixed model configuration. Will be removed in part 6 when mlxsw is fully converted to the unified model. Patches #2-#5 introduce two new FID attributes required for flooding configuration in the new model: 1. 'flood_rsp': Instructs the firmware to handle flooding configuration for this FID. Only set for router FIDs (rFIDs) which are used to connect a {Port, VLAN} to the router block. 2. 'bridge_type': Allows the device to determine the flood table (i.e., base index to the PGT table) for the FID. The first type will be used for FIDs in a VLAN-aware bridge and the second for FIDs representing VLAN-unaware bridges. Patch #6 configures the MPE table that determines the egress VLAN of a packet that is forwarded according to L2 multicast / flood. Patches #7-#11 add the PGT table and related APIs to allocate entries and set / clear ports in them. Patches #12-#13 convert the flooding configuration to use the new PGT APIs. ==================== Link: https://lore.kernel.org/r/20220627070621.648499-1-idosch@nvidia.comSigned-off-by:Paolo Abeni <pabeni@redhat.com>

The PGT (Port Group Table) table maps an index to a bitmap of local ports to which a packet needs to be replicated. This table is used for layer 2 multicast and flooding. In the legacy model, software did not interact with PGT table directly. Instead, it was accessed by firmware in response to registers such as SFTR and SMID. In the new model, the SFTR register is deprecated and software has full control over the PGT table using the SMID register. Use the new PGT APIs to allocate entries for flooding as part of flood tables initialization. Add mlxsw_sp_fid_flood_tables_fini() to free the allocated indexes. In addition, use PGT APIs to add/remove ports from PGT table. The existing code which configures the flood entries via SFTR2 will be removed later. Signed-off-by:

The PGT (Port Group Table) table maps an index to a bitmap of local ports to which a packet needs to be replicated. This table is used for layer 2 multicast and flooding. The index to PGT table which is called 'mid_index', is a result of 'mid_base' + 'fid_offset'. Using the legacy bridge model, firmware configures 'mid_base'. However, using the new model, software is responsible to configure it via SFGC register. The first 15K entries will be used for flooding and the rest for multicast. The table will look as follows: +----------------------------+ | | | 802.1q, unicast flooding | 4K entries | | +----------------------------+ | | | 802.1q, multicast flooding | 4K entries | | +----------------------------+ | | | 802.1q, broadcast flooding | 4K entries | | +----------------------------+ | 802.1d, unicast flooding | 1K entries +----------------------------+ | 802.1d, multicast flooding | 1K entries +----------------------------+ | 802.1d, broadcast flooding | 1K entries +----------------------------+ | | | | | Multicast entries | The rest of the table | | | | +----------------------------+ Add 'pgt_base' to 'struct mlxsw_sp_fid_family' and use it to calculate MID base, set 'SFGC.mid_base' as part of flood tables initialization.

Currently when bitmap of ports is needed, 'unsigned long *' type is used. The functions which use the bitmap assume its length according to its name, i.e., each function which gets a bitmap of ports queries the maximum number of ports and uses it as the size.

In Spectrum-1, the index into the MPE table - called switch multicast to port egress VID (SMPE) - is derived from the PGT entry, whereas in Spectrum-2 and later ASICs it is derived from the FID. Therefore, in Spectrum-1, the SMPE index needs to be programmed as part of the PGT entry via SMID register, while it is reserved for Spectrum-2 and later ASICs. Add 'pgt_smpe_index_valid' boolean as part of 'struct mlxsw_sp' and set it to true for Spectrum-1 and to false for the later ASICs. Add 'smpe_index_valid' as part of 'struct mlxsw_sp_pgt' and set it according to the value in 'struct mlxsw_sp' as part of PGT initialization. Signed-off-by:

In the legacy model, software did not interact with this table directly. Instead, it was accessed by firmware in response to registers such as SFTR and SMID. In the new model, the SFTR register is deprecated and software has full control over the PGT table using the SMID register. The entire state of the PGT table needs to be maintained in software because member ports in a PGT entry needs to be reference counted to avoid releasing entries which are still in use. Add the following APIs: 1. mlxsw_sp_pgt_{init, fini}() - allocate/free the PGT table. 2. mlxsw_sp_pgt_mid_alloc_range() - allocate a range of MID indexes in PGT. To be used by FID code during initialization to reserve specific PGT indexes for flooding entries. 3. mlxsw_sp_pgt_mid_free_range() - free indexes in a given range. 4. mlxsw_sp_pgt_mid_alloc() - allocate one MID index in the PGT at a non-specific range, just search for free index. To be used by MDB code. 5. mlxsw_sp_pgt_mid_free() - free the given index. Note that alloc() functions do not allocate the entries in software, just allocate IDs using 'idr'. Signed-off-by: -

The device includes two main tables to support layer 2 multicast (i.e., MDB and flooding). These are the PGT (Port Group Table) table and the MPE (Multicast Port Egress) table. - PGT is {MID -> (bitmap of local_port, SPME index)} - MPE is {(Local port, SMPE index) -> eVID} In the legacy model, software did not interact with MPE table as it was completely hidden in firmware. In the new model, software needs to populate the table itself in order to map from {Local port, SMPE} to an egress VID. This is done using the SMPE register. Configure SMPE register when a {Local port, VID} are mapped/unmapped to a 802.1d and 802.1q emulated FIDs. The MPE table is not relevant for rFIDs as firmware handles their flooding. Signed-off-by: -

Currently, 'bridge_type' is an attribute of 'struct mlxsw_sp_flood_table', which is defined per FID family. Instead, it can be an attribute of 'struct mlxsw_sp_fid_family' as all flood tables in the same family are of the same type. This change will ease the configuration of 'SFMR.flood_bridge_type' which will be added in the next patch. Signed-off-by:

Under the legacy bridge model, the field 'bridge_type' is used only in SFGC register, to determine the type of flood table (FID/FID offset). Under the unified bridge model, it will be used also in SFMR register. When a BUM packet needs to be flooded, SFGC is used to provide the 'mid_base' for PGT table. The access to SFGC is by {packet type, bridge type}. Under the unified bridge model, software is responsible for configuring 'bridge_type' as part of SFMR. As preparation for the new required configuration, rename 'enum mlxsw_reg_sfgc_bridge_type' to 'enum mlxsw_reg_bridge_type'. Then it can be used also in SFMR. In addition, align the names of the values to internal documentation. Signed-off-by: -

Using unified bridge model, RITR register no longer configures the rFID used for sub-port RIFs. It needs to be created by software via SFMR. Such FIDs need to be created with a special flood indication using 'SFMR.flood_rsp=1'. It means that for such FIDs, router sub-port flooding table will be used, this table is configured by firmware. Set the above mentioned field as part of FID initialization and FID edition, so then when other fields will be updated in SFMR, this field will store the correct value and will not be overwritten. Add 'flood_rsp' variable to 'struct mlxsw_sp_fid_family', set it to true for rFID and to false for the rest. Signed-off-by:

As part of transition to unified bridge model, many different firmware configurations are done. Some of the configuration that needs to be done for the unified bridge model is not valid under the legacy model, and would be rejected by the firmware. At the same time, the driver cannot switch to the unified bridge model until all of the code has been converted. To allow breaking the change into patches, and to not break driver behavior during the transition, add a boolean variable to indicate bridge model. Then, forbidden configurations will be skipped using the check - "if (!mlxsw_sp->ubridge)". The new variable is temporary for several sets, it will be removed when firmware will be configured to work with unified bridge model. Signed-off-by:

The addrconf_verify_rtnl() function uses a big if/elseif/elseif/... block to categorize each address by what type of attention it needs. An about-to-expire (RFC 4941) temporary address is one such category, but the previous elseif branch catches addresses that have already run out their prefered_lft. This means that if addrconf_verify_rtnl() fails to run in the necessary time window (i.e. REGEN_ADVANCE time units before the end of the prefered_lft), the temporary address will never be regenerated, and no temporary addresses will be available until each one's valid_lft runs out and manage_tempaddrs() begins anew. Fix this by moving the entire temporary address regeneration case out of that block. That block is supposed to implement the "destructive" part of an address's lifecycle, and regenerating a fresh temporary address is not, semantically speaking, actually tied to any particular lifecycle stage. The age test is also changed from `age >= prefered_lft - regen_advance` to `age + regen_advance >= prefered_lft` instead, to ensure no underflow occurs if the system administrator increases the regen_advance to a value greater than the already-set prefered_lft. Note that this does not fix the problem of addrconf_verify_rtnl() sometimes not running in time, resulting in the race condition described in RFC 4941 section 3.4 - it only ensures that the address is regenerated. Fixing THAT problem may require either using jiffies instead of seconds for all time arithmetic here, or always rounding up when regen_advance is converted to seconds. Signed-off-by:

'vlan_bitmap' is a bitmap and is used as such. So allocate it with devm_bitmap_zalloc() and its explicit bit size (i.e. VLAN_N_VID). This avoids the need of the VLAN_BITMAP_SIZE macro which: - needlessly has a 'nic_dev' parameter - should be "long" (and not byte) aligned, so that the bitmap semantic is respected This is in fact not an issue because VLAN_N_VID is 4096 at the time being, but devm_bitmap_zalloc() is less verbose and easier to understand.

Merge tag 'linux-can-next-for-5.20-20220625' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2022-06-25 this is a pull request of 22 patches for net-next/master. The first 2 patches target the xilinx driver. Srinivas Neeli's patch adds Transmitter Delay Compensation (TDC) support, a patch by me fixes a typo. The next patch is by me and fixes a typo in the m_can driver. Another patch by me allows the configuration of fixed bit rates without need for do_set_bittiming callback. The following 7 patches are by Vincent Mailhol and refactor the can-dev module and Kbuild, de-inline the can_dropped_invalid_skb() function, which has grown over the time, and drop outgoing skbs if the controller is in listen only mode. Max Staudt's patch fixes a reference in the networking/can.rst documentation. Vincent Mailhol provides 2 patches with cleanups for the etas_es58x driver. Conor Dooley adds bindings for the mpfs-can to the PolarFire SoC dtsi. Another patch by me allows the configuration of fixed data bit rates without need for do_set_data_bittiming callback. The last 5 patches are by Frank Jungclaus. They prepare the esd_usb driver to add support for the the CAN-USB/3 device in a later series. ==================== Signed-off-by:

Clément Léger says: ==================== net: add support for Renesas RZ/N1 ethernet su The Renesas RZ/N1 SoCs features an ethernet subsystem which contains (most notably) a switch, two GMACs, and a MII converter [1]. This series adds support for the switch and the MII converter. The MII converter present on this SoC has been represented as a PCS which sit between the MACs and the PHY. This PCS driver is probed from the device-tree since it requires to be configured. Indeed the MII converter also contains the registers that are handling the muxing of ports (Switch, MAC, HSR, RTOS, etc) internally to the SoC. The switch driver is based on DSA and exposes 4 ports + 1 CPU management port. It include basic bridging support as well as FDB and statistics support.
