November 2019 - Linux-stable-mirror

by Jarkko Nikula

Commit 9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM") nullified the runtime PM suspend/resume callback pointers while keeping the runtime PM enabled. This causes that device stays in D0 power state and sysfs /sys/bus/pci/devices/.../power/runtime_status shows "error" when runtime PM framework attempts to autosuspend the device. This is due PCI bus runtime PM which checks for driver runtime PM callbacks and returns with -ENOSYS if they are not set. Fix this by having a shared dummy runtime PM callback that returns with success.

[PATCH 1/3] drm/atomic: Take the atomic toys away from X

by Daniel Vetter

The -modesetting ddx has a totally broken idea of how atomic works: - doesn't disable old connectors, assuming they get auto-disable like with the legacy setcrtc - assumes ASYNC_FLIP is wired through for the atomic ioctl - not a single call to TEST_ONLY Iow the implementation is a 1:1 translation of legacy ioctls to atomic, which is a) broken b) pointless. We already have bugs in both i915 and amdgpu-DC where this prevents us from enabling neat features. If anyone ever cares about atomic in X we can easily add a new atomic level (req->value == 2) for X to get back the shiny toys. Since these broken versions of -modesetting have been shipping, there's really no other way to get out of this bind.

[PATCH 01/12] aio: fix async fsync creds

by Miklos Szeredi

Avi Kivity reports that on fuse filesystems running in a user namespace asyncronous fsync fails with EOVERFLOW. The reason is that f_ops->fsync() is called with the creds of the kthread performing aio work instead of the creds of the process originally submitting IOCB_CMD_FSYNC. Fuse sends the creds of the caller in the request header and it needs to translate the uid and gid into the server's user namespace. Since the kthread is running in init_user_ns, the translation will fail and the operation returns an error. It can be argued that fsync doesn't actually need any creds, but just zeroing out those fields in the header (as with requests that currently don't take creds) is a backward compatibility risk. Instead of working around this issue in fuse, solve the core of the problem by calling the filesystem with the proper creds.

[PATCH v1] power: supply: ltc2941-battery-gauge: fix use-after-free

by Sven Van Asbroeck

This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This could mean that the work function is still running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that that the work is properly cancelled, no longer running, and unable to re-schedule itself. This issue was detected with the help of Coccinelle.

SET/CLEAR_FEATURE for Remote Wakeup allowance not handled correctly. GET_STATUS handling provided not correct data on DATA Stage.
