2022-02-27docs: net: dsa: sja1105: document limitations of tc-flower rule VLAN awarenessVladimir Oltean1-0/+27
After change "net: dsa: tag_8021q: replace the SVL bridging with VLAN-unaware IVL bridging", tag_8021q enforces two different pvids on a port, depending on whether it is standalone or in a VLAN-unaware bridge. Up until now, there was a single pvid, represented by dsa_tag_8021q_rx_vid(), and that was used as the VLAN for VLAN-unaware virtual link rules, regardless of whether the port was bridged or standalone. To keep VLAN-unaware virtual links working, we need to follow whether the port is in a bridge or not, and update the VLAN ID from those rules. In fact we can't fully do that. Depending on whether the switch is VLAN-aware or not, we can accept Virtual Link rules with just the MAC DA, or with a MAC DA and a VID. So we already deny changes to the VLAN awareness of the switch. But the VLAN awareness may also change as a result of joining or leaving a bridge. One might say we could just allow the following: a port may leave a VLAN-unaware bridge while it has VLAN-unaware VL (tc-flower) rules, and the driver will update those with the new tag_8021q pvid for standalone mode, but the driver won't accept joining a bridge at all while VL rules were installed in standalone mode. This is sort of a compromise made because leaving a bridge is an operation that cannot be vetoed. But this sort of setup change is not fully supported, either: as mentioned, VLAN filtering changes can also be triggered by leaving a bridge, therefore, the existing veto we have in place for turning VLAN filtering off with VLAN-aware VL rules active still isn't fully effective. I really don't know how to deal with this in a way that produces predictable behavior for user space. Since at the moment, keeping this feature fully functional on constellation changes (not changing the tag_8021q port pvid when joining a bridge) is blocking progress for the DSA FDB isolation, I'd rather document it as a (potentially temporary) limitation and go on without it.

In the example I2C topology below (matching the second yaml example) we have MCTP devices on busses i2c1 and i2c6. MCTP-supporting busses are indicated by the 'mctp-controller' DT property on an I2C bus node. A mctp-i2c-controller I2C client DT node is placed at the top of the mux topology, since only the root I2C adapter will support I2C slave functionality. .-------. |eeprom | .------------. .------. /'-------' | adapter | | mux --@0,i2c5------' | i2c1 ----.*| --@1,i2c6--.--. |............| \'------' \ \ ......... | mctp-i2c- | \ \ \ .mctpB . | controller | \ \ '.0x30 . | | \ ......... \ '.......' | 0x50 | \ .mctpA . \ .........

2022-02-11dt-bindings: phy: Add `tx-p2p-microvolt` property bindingMarek Behún1-0/+103
Common PHYs and network PCSes often have the possibility to specify peak-to-peak voltage on the differential pair - the default voltage sometimes needs to be changed for a particular board. Add properties `tx-p2p-microvolt` and `tx-p2p-microvolt-names` for this purpose. The second property is needed to specify the mode for the corresponding voltage in the `tx-p2p-microvolt` property, if the voltage is to be used only for speficic mode. More voltage-mode pairs can be specified. Example usage with only one voltage (it will be used for all supported PHY modes, the `tx-p2p-microvolt-names` property is not needed in this case): tx-p2p-microvolt = <915000>; Example usage with voltages for multiple modes: tx-p2p-microvolt = <915000>, <1100000>, <1200000>; tx-p2p-microvolt-names = "2500base-x", "usb", "pcie"; Add these properties into a separate file phy/transmit-amplitude.yaml, which should be referenced by any binding that uses it.

This change adds a couple of new ioctls for mctp sockets: SIOCMCTPALLOCTAG and SIOCMCTPDROPTAG. These ioctls provide facilities for explicit allocation / release of tags, overriding the automatic allocate-on-send/release-on-reply and timeout behaviours. This allows userspace more control over messages that may not fit a simple request/response model. In order to indicate a pre-allocated tag to the sendmsg() syscall, we introduce a new flag to the struct sockaddr_mctp.smctp_tag value: MCTP_TAG_PREALLOC.

2022-02-03KVM: arm64: Workaround Cortex-A510's single-step and PAC trap errataJames Morse1-0/+2
Cortex-A510's erratum #2077057 causes SPSR_EL2 to be corrupted when single-stepping authenticated ERET instructions. A single step is expected, but a pointer authentication trap is taken instead. The erratum causes SPSR_EL1 to be copied to SPSR_EL2, which could allow EL1 to cause a return to EL2 with a guest controlled ELR_EL2. Because the conditions require an ERET into active-not-pending state, this is only a problem for the EL2 when EL2 is stepping EL1. In this case the previous SPSR_EL2 value is preserved in struct kvm_vcpu, and can be restored.
