2020-04-15net: mscc: ocelot: fix untagged packet drops when enslaving to vlan aware bridgeVladimir Oltean
To rehash a previous explanation given in commit 1c44ce560b4d ("net: mscc: ocelot: fix vlan_filtering when enslaving to bridge before link is up"), the switch driver operates the in a mode where a single VLAN can be transmitted as untagged on a particular egress port. That is the "native VLAN on trunk port" use case. The configuration for this native VLAN is driven in 2 ways: - Set the egress port rewriter to strip the VLAN tag for the native VID (as it is egress-untagged, after all). - Configure the ingress port to drop untagged and priority-tagged traffic, if there is no native VLAN. The intention of this setting is that a trunk port with no native VLAN should not accept untagged traffic. Since both of the above configurations for the native VLAN should only be done if VLAN awareness is requested, they are actually done from the ocelot_port_vlan_filtering function, after the basic procedure of toggling the VLAN awareness flag of the port. But there's a problem with that simplistic approach: we are trying to juggle with 2 independent variables from a single function: - Native VLAN of the port - its value is held in port->vid. - VLAN awareness state of the port - currently there are some issues here, more on that later*. The actual problem can be seen when enslaving the switch ports to a VLAN filtering bridge: 0. The driver configures a pvid of zero for each port, when in standalone mode. While the bridge configures a default_pvid of 1 for each port that gets added as a slave to it. 1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true. The VLAN-filtering-dependent portion of the native VLAN configuration is done, considering that the native VLAN is 0. 2. The bridge calls ocelot_vlan_add with vid=1, pvid=true, untagged=true. The native VLAN changes to 1 (change which gets propagated to hardware). 3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the VLAN-filtering-dependent portion of the native VLAN configuration, for the new native VLAN of 1. One can notice that after toggling "ip link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0 type bridge vlan_filtering 1", the new native VLAN finally makes it through and untagged traffic finally starts flowing again. But obviously that shouldn't be needed. So it is clear that 2 independent variables need to both re-trigger the native VLAN configuration. So we introduce the second variable as ocelot_port->vlan_aware. *Actually both the DSA Felix driver and the Ocelot driver already had each its own variable: - Ocelot: ocelot_port_private->vlan_aware - Felix: dsa_port->vlan_filtering but the common Ocelot library needs to work with a single, common, variable, so there is some refactoring done to move the vlan_aware property from the private structure into the common ocelot_port structure.

2020-04-11net: phy: marvell: Fix pause frame negotiationClemens Gruber
The negotiation of flow control / pause frame modes was broken since commit fcf1f59afc67 ("net: phy: marvell: rearrange to use genphy_read_lpa()") moved the setting of phydev->duplex below the phy_resolve_aneg_pause call. Due to a check of DUPLEX_FULL in that function, phydev->pause was no longer set. Fix it by moving the parsing of the status variable before the blocks dealing with the pause frames. As the Marvell 88E1510 datasheet does not specify the timing between the link status and the "Speed and Duplex Resolved" bit, we have to force the link down as long as the resolved bit is not set, to avoid reporting link up before we even have valid Speed/Duplex.

2020-04-07net: fec: set GPR bit on suspend by DT configuration.Martin Fuzzey
On some SoCs, such as the i.MX6, it is necessary to set a bit in the SoC level GPR register before suspending for wake on lan to work. The fec platform callback sleep_mode_enable was intended to allow this but the platform implementation was NAK'd back in 2015 [1] This means that, currently, wake on lan is broken on mainline for the i.MX6 at least. So implement the required bit setting in the fec driver by itself by adding a new optional DT property indicating the GPR register and adding the offset and bit information to the driver.

2020-04-06net: dsa: bcm_sf2: Do not register slave MDIO bus with OFFlorian Fainelli
We were registering our slave MDIO bus with OF and doing so with assigning the newly created slave_mii_bus of_node to the master MDIO bus controller node. This is a bad thing to do for a number of reasons: - we are completely lying about the slave MII bus is arranged and yet we still want to control which MDIO devices it probes. It was attempted before to play tricks with the bus_mask to perform that: https://www.spinics.net/lists/netdev/msg429420.html but the approach was rightfully rejected - the device_node reference counting is messed up and we are effectively doing a double probe on the devices we already probed using the master, this messes up all resources reference counts (such as clocks) The proper fix for this as indicated by David in his reply to the thread above is to use a platform data style registration so as to control exactly which devices we probe: https://www.spinics.net/lists/netdev/msg430083.html By using mdiobus_register(), our slave_mii_bus->phy_mask value is used as intended, and all the PHY addresses that must be redirected towards our slave MDIO bus is happening while other addresses get redirected towards the master MDIO bus.

2020-04-06tun: Don't put_page() for all negative return values from XDP programWill Deacon
When an XDP program is installed, tun_build_skb() grabs a reference to the current page fragment page if the program returns XDP_REDIRECT or XDP_TX. However, since tun_xdp_act() passes through negative return values from the XDP program, it is possible to trigger the error path by mistake and accidentally drop a reference to the fragments page without taking one, leading to a spurious free. This is believed to be the cause of some KASAN use-after-free reports from syzbot [1], although without a reproducer it is not possible to confirm whether this patch fixes the problem. Ensure that we only drop a reference to the fragments page if the XDP transmit or redirect operations actually fail.

2020-04-03net: dsa: mt7530: fix null pointer dereferencing in port5 setupChuanhong Guo
The 2nd gmac of mediatek soc ethernet may not be connected to a PHY and a phy-handle isn't always available. Unfortunately, mt7530 dsa driver assumes that the 2nd gmac is always connected to switch port 5 and setup mt7530 according to phy address of 2nd gmac node, causing null pointer dereferencing when phy-handle isn't defined in dts. This commit fix this setup code by checking return value of of_parse_phandle before using it.

2020-04-03net: phy: micrel: kszphy_resume(): add delay after genphy_resume() before ↵Oleksij Rempel
accessing PHY registers After the power-down bit is cleared, the chip internally triggers a global reset. According to the KSZ9031 documentation, we have to wait at least 1ms for the reset to finish. If the chip is accessed during reset, read will return 0xffff, while write will be ignored. Depending on the system performance and MDIO bus speed, we may or may not run in to this issue. This bug was discovered on an iMX6QP system with KSZ9031 PHY and attached PHY interrupt line. If IRQ was used, the link status update was lost. In polling mode, the link status update was always correct. The investigation showed, that during a read-modify-write access, the read returned 0xffff (while the chip was still in reset) and corresponding write hit the chip _after_ reset and triggered (due to the 0xffff) another reset in an undocumented bit (register 0x1f, bit 1), resulting in the next write being lost due to the new reset cycle. This patch fixes the issue by adding a 1...2 ms sleep after the genphy_resume().
