[ Upstream commit 536fab5b ] 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.

This simply adds the same gating check to another code path, and thus should prevent the same devices from erroneously obtaining an ipv6 link-local address.

commit aa9f7d51 upstream. Using an empty (malformed) nodelist that is not caught during mount option parsing leads to a stack-out-of-bounds access. The option string that was used was: "mpol=prefer:,". However, MPOL_PREFERRED requires a single node number, which is not being provided here. Add a check that 'nodes' is not empty after parsing for MPOL_PREFERRED's nodeid. Fixes: 095f1fc4 ("mempolicy: rework shmem mpol parsing and display") Reported-by:

The lower bound is represented by 'qoffset' and the upper limit for hash value is 'qcount + qoffset'.

commit 9c80662a upstream. Some HP Pavilion x2 10 models use an AXP288 for charging and fuel-gauge. We use a native power_supply / PMIC driver in this case, because on most models with an AXP288 the ACPI AC / Battery code is either completely missing or relies on custom / proprietary ACPI OpRegions which Linux does not implement. The native drivers mostly work fine, but there are 2 problems: 1. These model uses a Type-C connector for charging which the AXP288 does not support. As long as a Type-A charger (which uses the USB data pins for charger type detection) is used everything is fine. But if a Type-C charger is used (such as the charger shipped with the device) then the charger is not recognized. So we end up slowly discharging the device even though a charger is connected, because we are limiting the current from the charger to 500mA. To make things worse this happens with the device's official charger. Looking at the ACPI tables HP has "solved" the problem of the AXP288 not being able to recognize Type-C chargers by simply always programming the input-current-limit at 3000mA and relying on a Vhold setting of 4.7V (normally 4.4V) to limit the current intake if the charger cannot handle this. 2. If no charger is connected when the machine boots then it boots with the vbus-path disabled. On other devices this is done when a 5V boost converter is active to avoid the PMIC trying to charge from the 5V boost output. This is done when an OTG host cable is inserted and the ID pin on the micro-B receptacle is pulled low, the ID pin has an ACPI event handler associated with it which re-enables the vbus-path when the ID pin is pulled high when the OTG cable is removed. The Type-C connector has no ID pin, there is no ID pin handler and there appears to be no 5V boost converter, so we end up not charging because the vbus-path is disabled, until we unplug the charger which automatically clears the vbus-path disable bit and then on the second plug-in of the adapter we start charging. The HP Pavilion x2 10 models with an AXP288 do have mostly working ACPI AC / Battery code which does not rely on custom / proprietary ACPI OpRegions. So one possible solution would be to blacklist the AXP288 native power_supply drivers and add the HP Pavilion x2 10 with AXP288 DMI ids to the list of devices which should use the ACPI AC / Battery code even though they have an AXP288 PMIC. This would require changes to 4 files: drivers/acpi/ac.c, drivers/power/supply/axp288_charger.c, drivers/acpi/battery.c and drivers/power/supply/axp288_fuel_gauge.c. Beside needing adding the same DMI matches to 4 different files, this approach also triggers problem 2. from above, but then when suspended, during suspend the machine will not wakeup because the vbus path is disabled by the AML code when not charging, so the Vbus low-to-high IRQ is not triggered, the CPU never wakes up and the device does not charge even though the user likely things it is charging, esp. since the charge status LED is directly coupled to an adapter being plugged in and does not reflect actual charging. This could be worked by enabling vbus-path explicitly from say the axp288_charger driver's suspend handler. So neither situation is ideal, in both cased we need to explicitly enable the vbus-path to work around different variants of problem 2 above, this requires a quirk in the axp288_charger code. If we go the route of using the ACPI AC / Battery drivers then we need modifications to 3 other drivers; and we need to partially disable the axp288_charger code, while at the same time keeping it around to enable vbus-path on suspend. OTOH we can copy the hardcoding of 3A input-current-limit (we never touch Vhold, so that would stay at 4.7V) to the axp288_charger code, which needs changes regardless, then we concentrate all special handling of this interesting device model in the axp288_charger code. That is what this commit does. Cc: stable@vger.kernel.org BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1791098Signed-off-by:

[ Upstream commit 785d74ec ] Even though INITRAMFS_SOURCE kconfig option isn't set in most of defconfigs it is used (set) extensively by various build systems. Commit f26661e1 ("initramfs: make initramfs compression choice non-optional") has changed default compression mode. Previously we compress initramfs using available compression algorithm. Now we don't use any compression at all by default. It significantly increases the image size in case of build system chooses embedded initramfs. Initially I faced with this issue while using buildroot. As of today it's not possible to set preferred compression mode in target defconfig as this option depends on INITRAMFS_SOURCE being set. Modification of all build systems either doesn't look like good option. Let's instead rewrite initramfs compression mode choices list the way that "INITRAMFS_COMPRESSION_NONE" will be the last option in the list. In that case it will be chosen only if all other options (which implements any compression) are not available. Signed-off-by:

[ Upstream commit dec9de2a ] This fixes a problem found on the MacBookPro 2017 Retina panel: The panel reports 10 bpc color depth in its EDID, and the firmware chooses link settings at boot which support enough bandwidth for 10 bpc (324000 kbit/sec aka LINK_RATE_RBR2 aka 0xc), but the DP_MAX_LINK_RATE dpcd register only reports 2.7 Gbps (multiplier value 0xa) as possible, in direct contradiction of what the firmware successfully set up. This restricts the panel to 8 bpc, not providing the full color depth of the panel on Linux <= 5.5. Additionally, commit '4a8ca46b ("drm/amd/display: Default max bpc to 16 for eDP")' introduced into Linux 5.6-rc1 will unclamp panel depth to its full 10 bpc, thereby requiring a eDP bandwidth for all modes that exceeds the bandwidth available and causes all modes to fail validation -> No modes for the laptop panel -> failure to set any mode -> Panel goes dark. This patch adds a quirk specific to the MBP 2017 15" Retina panel to override reported max link rate to the correct maximum of 0xc = LINK_RATE_RBR2 to fix the darkness and reduced display precision. Please apply for Linux 5.6+ to avoid regressing Apple MBP panel support. Signed-off-by:

[ Upstream commit 582eea23 ] Under certain circumstances, depending on the order of addresses on the interfaces, it could be that sctp_v[46]_get_dst() would return a dst with a mismatched struct flowi. For example, if when walking through the bind addresses and the first one is not a match, it saves the dst as a fallback (added in 410f0383), but not the flowi. Then if the next one is also not a match, the previous dst will be returned but with the flowi information for the 2nd address, which is wrong. The fix is to use a locally stored flowi that can be used for such attempts, and copy it to the parameter only in case it is a possible match, together with the corresponding dst entry. The patch updates IPv6 code mostly just to be in sync. Even though the issue is also present there, it fallback is not expected to work with IPv6.

[ Upstream commit 25629fda ] when creating a new ipip interface with no local/remote configuration, the lookup is done with TUNNEL_NO_KEY flag, making it impossible to match the new interface (only possible match being fallback or metada case interface); e.g: `ip link add tunl1 type ipip dev eth0` To fix this case, adding a flag check before the key comparison so we permit to match an interface with no local/remote config; it also avoids breaking possible userland tools relying on TUNNEL_NO_KEY flag and uninitialised key. context being on my side, I'm creating an extra ipip interface attached to the physical one, and moving it to a dedicated namespace.

commit d79e9d7c upstream. The correct setting for the RGMII ports on LS1046ARDB is to enable delay on both Rx and Tx so the interface mode used must be PHY_INTERFACE_MODE_RGMII_ID. Since commit 1b3047b5 ("net: phy: realtek: add support for configuring the RX delay on RTL8211F") the Realtek 8211F PHY driver has control over the RGMII RX delay and it is disabling it for RGMII_TXID. The LS1046ARDB uses two such PHYs in RGMII_ID mode but in the device tree the mode was described as "rgmii". Changing the phy-connection-type to "rgmii-id" to address the issue.

The LS1043ARDB uses two such PHYs in RGMII_ID mode but in the device tree the mode was described as "rgmii_txid". This issue was not apparent at the time as the PHY driver took the same action for RGMII_TXID and RGMII_ID back then but it became visible (RX no longer working) after the above patch. Changing the phy-connection-type to "rgmii-id" to address the issue. Fixes: bf02f2ff ("arm64: dts: add LS1043A DPAA FMan support") Signed-off-by:

commit 0c5220a3 upstream. Commit a758f50f ("mtd: onenand: omap2: Configure driver from DT") started using DT specified timings for GPMC, and as a result the OneNAND stopped working on N900 as we had wrong values in the DT. Fix by updating the values to bootloader timings that have been tested to be working on Nokia N900 with OneNAND manufacturers: Samsung, Numonyx.

commit 636b45b8 upstream. The current set minimum voltage of 730000µV seems to be wrong. I don't know the document which specifies that but the imx6qdl datasheets says that the minimum voltage should be 0.925V for VDD_ARM (LDO bypassed, lowest opp) and 1.15V for VDD_SOC (LDO bypassed, lowest opp).

commit db2c5494 upstream. This patch fixes an off-by-one error in strncpy size argument in tools/perf/util/map.c. The issue is that in: strncmp(filename, "/system/lib/", 11) the passed string literal: "/system/lib/" has 12 bytes (without the NULL byte) and the passed size argument is 11. As a result, the logic won't match the ending "/" byte and will pass filepaths that are stored in other directories e.g. "/system/libmalicious/bin" or just "/system/libmalicious". This functionality seems to be present only on Android. I assume the /system/ directory is only writable by the root user, so I don't think this bug has much (or any) security impact.

commit 8262e6f9 upstream. This patch reverts 58292104 ("net: ks8851-ml: Fix 16-bit IO operation") and edacb098 ("net: ks8851-ml: Fix 16-bit data access"), because it turns out these were only necessary due to buggy hardware. This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.

commit 0c625ccf upstream. There are at least 3 models of the HP x2 10 models: Bay Trail SoC + AXP288 PMIC Cherry Trail SoC + AXP288 PMIC Cherry Trail SoC + TI PMIC Like on the other HP x2 10 models we need to ignore wakeup for ACPI GPIO events on the external embedded-controller pin to avoid spurious wakeups on the HP x2 10 CHT + AXP288 model too. This commit adds an extra DMI based quirk for the HP x2 10 CHT + AXP288 model, ignoring wakeups for ACPI GPIO events on the EC interrupt pin on this model. This fixes spurious wakeups from suspend on this model. Fixes: aa23ca3d ("gpiolib: acpi: Add honor_wakeup module-option + quirk mechanism") Reported-and-tested-by:
