2019-09-24thermal: Add some error messagesAmit Kucheria1-4/+13
When registering a thermal zone device, we currently return -EINVAL in four cases. This makes it a little hard to debug the real cause of the failure. Print some error messages to make it easier for developer to figure out what happened. Signed-off-by: Amit Kucheria <[email protected]> Signed-off-by: Zhang Rui <[email protected]>
2019-09-24thermal: Fix use-after-free when unregistering thermal zone deviceIdo Schimmel1-1/+1
thermal_zone_device_unregister() cancels the delayed work that polls the thermal zone, but it does not wait for it to finish. This is racy with respect to the freeing of the thermal zone device, which can result in a use-after-free [1]. Fix this by waiting for the delayed work to finish before freeing the thermal zone device. Note that thermal_zone_device_set_polling() is never invoked from an atomic context, so it is safe to call cancel_delayed_work_sync() that can block.

2019-09-24thermal_hwmon: Sanitize thermal_zone typeStefan Mavrodiev1-2/+6
When calling thermal_add_hwmon_sysfs(), the device type is sanitized by replacing '-' with '_'. However tz->type remains unsanitized. Thus calling thermal_hwmon_lookup_by_type() returns no device. And if there is no device, thermal_remove_hwmon_sysfs() fails with "hwmon device lookup failed!". The result is unregisted hwmon devices in the sysfs.

2019-08-16arm64: ftrace: Ensure module ftrace trampoline is coherent with I-sideWill Deacon1-9/+13
The initial support for dynamic ftrace trampolines in modules made use of an indirect branch which loaded its target from the beginning of a special section (e71a4e1bebaf7 ("arm64: ftrace: add support for far branches to dynamic ftrace")). Since no instructions were being patched, no cache maintenance was needed. However, later in be0f272bfc83 ("arm64: ftrace: emit ftrace-mod.o contents through code") this code was reworked to output the trampoline instructions directly into the PLT entry but, unfortunately, the necessary cache maintenance was overlooked. Add a call to __flush_icache_range() after writing the new trampoline instructions but before patching in the branch to the trampoline.

2019-08-16x86/boot: Save fields explicitly, zero out everything elseJohn Hubbard1-15/+48
Recent gcc compilers (gcc 9.1) generate warnings about an out of bounds memset, if the memset goes accross several fields of a struct. This generated a couple of warnings on x86_64 builds in sanitize_boot_params(). Fix this by explicitly saving the fields in struct boot_params that are intended to be preserved, and zeroing all the rest. [ tglx: Tagged for stable as it breaks the warning free build there as well ] Suggested-by: Thomas Gleixner <[email protected]> Suggested-by: H.
