Setting of the port flag `NFP_PORT_CHANGED`, introduced to ensure the correct reading of EEPROM data, causes a fatal kernel NULL pointer dereference in cases where the target netdev type cannot be determined.

2022-11-19nfp: fill splittable of devlink_port_attrs correctlyDiana Wang1-1/+1
The error is reflected in that it shows wrong splittable status of port when executing "devlink port show". The reason which leads the error is that the assigned operation of splittable is just a simple negation operation of split and it does not consider port lanes quantity. A splittable port should have several lanes that can be split(lanes quantity > 1). If without the judgement, it will show wrong message for some firmware, such as 2x25G, 2x10G.

You'd think people know that the internal 100BASE-TX PHY on the SJA1110 responds only to clause 22 MDIO transactions, but they don't :) When a clause 45 transaction is attempted, sja1105_base_tx_mdio_read() and sja1105_base_tx_mdio_write() don't expect "reg" to contain bit 30 set (MII_ADDR_C45) and pack this value into the SPI transaction buffer. But the field in the SPI buffer has a width smaller than 30 bits, so we see this confusing message from the packing() API rather than a proper rejection of C45 transactions: Call trace: dump_stack+0x1c/0x38 sja1105_pack+0xbc/0xc0 [sja1105] sja1105_xfer+0x114/0x2b0 [sja1105] sja1105_xfer_u32+0x44/0xf4 [sja1105] sja1105_base_tx_mdio_read+0x44/0x7c [sja1105] mdiobus_read+0x44/0x80 get_phy_c45_ids+0x70/0x234 get_phy_device+0x68/0x15c fwnode_mdiobus_register_phy+0x74/0x240 of_mdiobus_register+0x13c/0x380 sja1105_mdiobus_register+0x368/0x490 [sja1105] sja1105_setup+0x94/0x119c [sja1105] Cannot store 401d2405 inside bits 24-4 (would truncate) Fixes: 5a8f09748ee7 ("net: dsa: sja1105: register the MDIO buses for 100base-T1 and 100base-TX") Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

Yoga laptops Commit 3ae86d2d4704 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops to manually toggle the fn-lock LED because the EC does not do it itself. However, the same WMI ID is also sent on some Yoga laptops. Here, setting the fn-lock state is not valid behavior, and causes the EC to spam interrupts until the laptop is rebooted. Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to manually set the LED on models on this list.

2022-11-15platform/surface: aggregator: Do not check for repeated unsequenced packetsMaximilian Luz1-4/+20
Currently, we check any received packet whether we have already seen it previously, regardless of the packet type (sequenced / unsequenced). We do this by checking the sequence number. This assumes that sequence numbers are valid for both sequenced and unsequenced packets. However, this assumption appears to be incorrect. On some devices, the sequence number field of unsequenced packets (in particular HID input events on the Surface Pro 9) is always zero. As a result, the current retransmission check kicks in and discards all but the first unsequenced packet, breaking (among other things) keyboard and touchpad input. Note that we have, so far, only seen packets being retransmitted in sequenced communication. In particular, this happens when there is an ACK timeout, causing the EC (or us) to re-send the packet waiting for an ACK. Arguably, retransmission / duplication of unsequenced packets should not be an issue as there is no logical condition (such as an ACK timeout) to determine when a packet should be sent again. Therefore, remove the retransmission check for unsequenced packets entirely to resolve the issue.

2022-11-15platform/x86/intel: pmc: Don't unconditionally attach Intel PMC when virtualizedRoger Pau Monné1-0/+9
The current logic in the Intel PMC driver will forcefully attach it when detecting any CPU on the intel_pmc_core_platform_ids array, even if the matching ACPI device is not present. There's no checking in pmc_core_probe() to assert that the PMC device is present, and hence on virtualized environments the PMC device probes successfully, even if the underlying registers are not present. Before commit 21ae43570940 ("platform/x86: intel_pmc_core: Substitute PCI with CPUID enumeration") the driver would check for the presence of a specific PCI device, and that prevented the driver from attaching when running virtualized. Fix by only forcefully attaching the PMC device when not running virtualized. Note that virtualized platforms can still get the device to load if the appropriate ACPI device is present on the tables provided to the VM. Make an exception for the Xen initial domain, which does have full hardware access, and hence can attach to the PMC if present.
