2022-09-20net: ipa: properly limit modem routing table useAlex Elder
IPA can route packets between IPA-connected entities. The AP and modem are currently the only such entities supported, and no routing is required to transfer packets between them. The number of entries in each routing table is fixed, and defined at initialization time. Some of these entries are designated for use by the modem, and the rest are available for the AP to use. The AP sends a QMI message to the modem which describes (among other things) information about routing table memory available for the modem to use. Currently the QMI initialization packet gives wrong information in its description of routing tables. What *should* be supplied is the maximum index that the modem can use for the routing table memory located at a given location. The current code instead supplies the total *number* of routing table entries. Furthermore, the modem is granted the entire table, not just the subset it's supposed to use. This patch fixes this. First, the ipa_mem_bounds structure is generalized so its "end" field can be interpreted either as a final byte offset, or a final array index. Second, the IPv4 and IPv6 (non-hashed and hashed) table information fields in the QMI ipa_init_modem_driver_req structure are changed to be ipa_mem_bounds rather than ipa_mem_array structures. Third, we set the "end" value for each routing table to be the last index, rather than setting the "count" to be the number of indices. Finally, instead of allowing the modem to use all of a routing table's memory, it is limited to just the portion meant to be used by the modem. In all versions of IPA currently supported, that is IPA_ROUTE_MODEM_COUNT (8) entries. Update a few comments for clarity.

2022-09-20net: ipa: don't reuse variable namesAlex Elder
In ipa_endpoint_init_hdr(), as well as ipa_endpoint_init_hdr_ext(), a top-level automatic variable named "offset" is used to represent the offset of a register. However, deeper within each of those functions is *another* definition of a local variable with the same name, representing something else. Scoping rules ensure the result is what was intended, but this variable name reuse is bad practice and makes the code confusing. Fix this by naming the inner variable "off".

2022-09-20net: ipa: don't define unneeded GSI register offsetsAlex Elder
Each GSI execution environment (EE) is able to access many of the GSI registers associated with the other EEs. A block of GSI registers is contained within a region of memory, and an EE's register offset can be determined by adding the register's base offset to the product of the EE ID and a fixed constant. Despite this possibility, the AP IPA code *never* accesses any GSI registers other than its own. So there's no need to define the macros that compute register offsets for other EEs. Redefine the AP access macros to compute the offset the way the more general "any EE" macro would, and get rid of the unneeded macros.

2022-09-20net: ethernet: adi: Add ADIN1110 supportAlexandru Tachici
The ADIN1110 is a low power single port 10BASE-T1L MAC-PHY designed for industrial Ethernet applications. It integrates an Ethernet PHY core with a MAC and all the associated analog circuitry, input and output clock buffering. ADIN1110 MAC-PHY encapsulates the ADIN1100 PHY. The PHY registers can be accessed through the MDIO MAC registers. We are registering an MDIO bus with custom read/write in order to let the PHY to be discovered by the PAL. This will let the ADIN1100 Linux driver to probe and take control of the PHY. The ADIN2111 is a low power, low complexity, two-Ethernet ports switch with integrated 10BASE-T1L PHYs and one serial peripheral interface (SPI) port. The device is designed for industrial Ethernet applications using low power constrained nodes and is compliant with the IEEE 802.3cg-2019 Ethernet standard for long reach 10 Mbps single pair Ethernet (SPE). The switch supports various routing configurations between the two Ethernet ports and the SPI host port providing a flexible solution for line, daisy-chain, or ring network topologies. The ADIN2111 supports cable reach of up to 1700 meters with ultra low power consumption of 77 mW. The two PHY cores support the 1.0 V p-p operating mode and the 2.4 V p-p operating mode defined in the IEEE 802.3cg standard. The device integrates the switch, two Ethernet physical layer (PHY) cores with a media access control (MAC) interface and all the associated analog circuitry, and input and output clock buffering. The device also includes internal buffer queues, the SPI and subsystem registers, as well as the control logic to manage the reset and clock control and hardware pin configuration. Access to the PHYs is exposed via an internal MDIO bus. Writes/reads can be performed by reading/writing to the ADIN2111 MDIO registers via SPI. On probe, for each port, a struct net_device is allocated and registered. When both ports are added to the same bridge, the driver will enable offloading of frame forwarding at the hardware level. Driver offers STP support. Normal operation on forwarding state. Allows only frames with the 802.1d DA to be passed to the host when in any of the other states. When both ports of ADIN2111 belong to the same SW bridge a maximum of 12 FDB entries will offloaded by the hardware and are marked as such.

2022-09-20net: dsa: microchip: lan937x: fix maximum frame length checkRakesh Sankaranarayanan
Maximum frame length check is enabled in lan937x switch on POR, But it is found to be disabled on driver during port setup operation. Due to this, packets are not dropped when transmitted with greater than configured value. For testing, setup made for lan1->lan2 transmission and configured lan1 interface with a frame length (less than 1500 as mentioned in documentation) and transmitted packets with greater than configured value. Expected no packets at lan2 end, but packets observed at lan2. Based on the documentation, packets should get discarded if the actual packet length doesn't match the frame length configured. Frame length check should be disabled only for cascaded ports due to tailtags. This feature was disabled on ksz9477 series due to ptp issue, which is not in lan937x series. But since lan937x took ksz9477 as base, frame length check disabled here as well. Patch added to remove this portion from port setup so that maximum frame length check will be active for normal ports.

2022-09-20net: dsa: felix: add support for changing DSA masterVladimir Oltean
Changing the DSA master means different things depending on the tagging protocol in use. For NPI mode ("ocelot" and "seville"), there is a single port which can be configured as NPI, but DSA only permits changing the CPU port affinity of user ports one by one. So changing a user port to a different NPI port globally changes what the NPI port is, and breaks the user ports still using the old one. To address this while still permitting the change of the NPI port, require that the user ports which are still affine to the old NPI port are down, and cannot be brought up until they are all affine to the same NPI port. The tag_8021q mode ("ocelot-8021q") is more flexible, in that each user port can be freely assigned to one CPU port or to the other. This works by filtering host addresses towards both tag_8021q CPU ports, and then restricting the forwarding from a certain user port only to one of the two tag_8021q CPU ports. Additionally, the 2 tag_8021q CPU ports can be placed in a LAG. This works by enabling forwarding via PGID_SRC from a certain user port towards the logical port ID containing both tag_8021q CPU ports, but then restricting forwarding per packet, via the LAG hash codes in PGID_AGGR, to either one or the other. When we change the DSA master to a LAG device, DSA guarantees us that the LAG has at least one lower interface as a physical DSA master. But DSA masters can come and go as lowers of that LAG, and ds->ops->port_change_master() will not get called, because the DSA master is still the same (the LAG). So we need to hook into the ds->ops->port_lag_{join,leave} calls on the CPU ports and update the logical port ID of the LAG that user ports are assigned to.

Additionally, since DSA masters may now also be LAG interfaces, and this will translate into a call to port_lag_join on the CPU ports, there may be extra restrictions there. Propagate the netlink extack to this DSA method in order for drivers to give a meaningful error message back to the user.

2022-09-20net: dsa: introduce dsa_port_get_master()Vladimir Oltean
There is a desire to support for DSA masters in a LAG. That configuration is intended to work by simply enslaving the master to a bonding/team device. But the physical DSA master (the LAG slave) still has a dev->dsa_ptr, and that cpu_dp still corresponds to the physical CPU port. However, we would like to be able to retrieve the LAG that's the upper of the physical DSA master. In preparation for that, introduce a helper called dsa_port_get_master() that replaces all occurrences of the dp->cpu_dp->master pattern. The distinction between LAG and non-LAG will be made later within the helper itself.

2022-09-19sfc: fix null pointer dereference in efx_hard_start_xmitÍñigo Huguet
Trying to get the channel from the tx_queue variable here is wrong because we can only be here if tx_queue is NULL, so we shouldn't dereference it. As the above comment in the code says, this is very unlikely to happen, but it's wrong anyway so let's fix it. I hit this issue because of a different bug that caused tx_queue to be NULL. If that happens, this is the error message that we get here: BUG: unable to handle kernel NULL pointer dereference at 0000000000000020 [...] RIP: 0010:efx_hard_start_xmit+0x153/0x170 [sfc] Fixes: 12804793b17c ("sfc: decouple TXQ type from label") Reported-by: Tianhao Zhao <tizhao@redhat.com> Signed-off-by: Íñigo Huguet <ihuguet@redhat.com> Acked-by: Edward Cree <ecree.xilinx@gmail.com> Link: https://lore.kernel.org/r/20220914111135.21038-1-ihuguet@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-09-19sfc: fix TX channel offset when using legacy interruptsÍñigo Huguet
In legacy interrupt mode the tx_channel_offset was hardcoded to 1, but that's not correct if efx_sepparate_tx_channels is false. In that case, the offset is 0 because the tx queues are in the single existing channel at index 0, together with the rx queue. Without this fix, as soon as you try to send any traffic, it tries to get the tx queues from an uninitialized channel getting these errors: WARNING: CPU: 1 PID: 0 at drivers/net/ethernet/sfc/tx.c:540 efx_hard_start_xmit+0x12e/0x170 [sfc] [...] RIP: 0010:efx_hard_start_xmit+0x12e/0x170 [sfc] [...] Call Trace: <IRQ> dev_hard_start_xmit+0xd7/0x230 sch_direct_xmit+0x9f/0x360 __dev_queue_xmit+0x890/0xa40 [...] BUG: unable to handle kernel NULL pointer dereference at 0000000000000020 [...] RIP: 0010:efx_hard_start_xmit+0x153/0x170 [sfc] [...] Call Trace: <IRQ> dev_hard_start_xmit+0xd7/0x230 sch_direct_xmit+0x9f/0x360 __dev_queue_xmit+0x890/0xa40 [...] Fixes: c308dfd1b43e ("sfc: fix wrong tx channel offset with efx_separate_tx_channels") Reported-by: Tianhao Zhao <tizhao@redhat.com> Signed-off-by: Íñigo Huguet <ihuguet@redhat.com> Acked-by: Edward Cree <ecree.xilinx@gmail.com> Link: https://lore.kernel.org/r/20220914103648.16902-1-ihuguet@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
