2021-04-13platform/x86: add Gigabyte WMI temperature driverThomas Weißschuh
Tested with * X570 I Aorus Pro Wifi (rev 1.0) * B550M DS3H * B550 Gaming X V2 (rev.1.x) * Z390 I AORUS PRO WIFI (rev. 1.0) Those mainboards contain an ITE chips for management and monitoring. They could also be handled by drivers/hwmon/i87.c. But the SuperIO range used by i87 is already claimed and used by the firmware. The following warning is printed at boot: kernel: ACPI Warning: SystemIO range 0x0000000000000A45-0x0000000000000A46 conflicts with OpRegion 0x0000000000000A45-0x0000000000000A46 (\GSA1.SIO1) (20200528/utaddress-204) kernel: ACPI: This conflict may cause random problems and system instability kernel: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver This driver implements such an ACPI driver. Unfortunately not all sensor registers are handled by the firmware and even less are exposed via WMI.

2021-04-13platform/x86: intel_pmc_core: export platform global reset bits via etr3 ↵Tamar Mashiah
sysfs file During PCH (platform/board) manufacturing process a global platform reset has to be induced in order for the configuration changes take the effect upon following platform reset. This is an internal platform state and is not intended to be used in the regular platform resets. The setting is exposed via ETR3 (Extended Test Mode Register 3). After the manufacturing process is completed the register cannot be written anymore and is hardware locked. This setting was commonly done by accessing PMC registers via /dev/mem but due to security concerns /dev/mem access is much more restricted, hence the reason for exposing this setting via the dedicated sysfs interface. To prevent post manufacturing abuse the register is protected by hardware locking and the file is set to read-only mode via is_visible handler. The register in MMIO space is defined for Cannon Lake and newer PCHs.

2021-04-13platform/x86: thinkpad_acpi: Correct thermal sensor allocationMark Pearson
On recent Thinkpad platforms it was reported that temp sensor 11 was always incorrectly displaying 66C. It turns out the reason for this is that this location in EC RAM is not a temperature sensor but is the power supply ID (offset 0xC2). Based on feedback from the Lenovo firmware team the EC RAM version can be determined and for the current version (3) only the 0x78 to 0x7F range is used for temp sensors. I don't have any details for earlier versions so I have left the implementation unaltered there. Note - in this block only 0x78 and 0x79 are officially designated (CPU & GPU sensors). The use of the other locations in the block will vary from platform to platform; but the existing logic to detect a sensor presence holds.

2021-04-12net: phy: marvell: fix detection of PHY on Topaz switchesPali Rohár
Since commit fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading"), Linux reports the temperature of Topaz hwmon as constant -75°C. This is because switches from the Topaz family (88E6141 / 88E6341) have the address of the temperature sensor register different from Peridot. This address is instead compatible with 88E1510 PHYs, as was used for Topaz before the above mentioned commit. Create a new mapping table between switch family and PHY ID for families which don't have a model number. And define PHY IDs for Topaz and Peridot families. Create a new PHY ID and a new PHY driver for Topaz's internal PHY. The only difference from Peridot's PHY driver is the HWMON probing method. Prior this change Topaz's internal PHY is detected by kernel as: PHY [...] driver [Marvell 88E6390] (irq=63) And afterwards as: PHY [...] driver [Marvell 88E6341 Family] (irq=63) Signed-off-by: Pali Rohár <pali@kernel.org> BugLink: https://github.com/globalscaletechnologies/linux/issues/1 Fixes: fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading") Reviewed-by: Marek Behún <kabel@kernel.org> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

Since fuse just passes ioctl args through to/from server, converting to the fileattr API is more involved, than most other filesystems. Both .fileattr_set() and .fileattr_get() need to obtain an open file to operate on. The simplest way is with the following sequence: FUSE_OPEN FUSE_IOCTL FUSE_RELEASE If this turns out to be a performance problem, it could be optimized for the case when there's already a file (any file) open for the inode.

Add stacking for the fileattr operations. Add hack for calling security_file_ioctl() for now. Probably better to have a pair of specific hooks for these operations. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

2021-04-12vfs: add fileattr opsMiklos Szeredi
There's a substantial amount of boilerplate in filesystems handling FS_IOC_[GS]ETFLAGS/ FS_IOC_FS[GS]ETXATTR ioctls. Also due to userspace buffers being involved in the ioctl API this is difficult to stack, as shown by overlayfs issues related to these ioctls. Introduce a new internal API named "fileattr" (fsxattr can be confused with xattr, xflags is inappropriate, since this is more than just flags). There's significant overlap between flags and xflags and this API handles the conversions automatically, so filesystems may choose which one to use. In ->fileattr_get() a hint is provided to the filesystem whether flags or xattr are being requested by userspace, but in this series this hint is ignored by all filesystems, since generating all the attributes is cheap. If a filesystem doesn't implemement the fileattr API, just fall back to f_op->ioctl(). When all filesystems are converted, the fallback can be removed. 32bit compat ioctls are now handled by the generic code as well. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
