2014-07-01	tmon: set umask to a reasonable value	Neil Horman	1	-1/+1
	Currently, the tmon umask value is set to 0, which means whatever the permission mask in the shell are when starting tmon in daemon mode are what the permissions of any created files will be. We should likely set something more explicit, so lets go with the usual 022 Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Jacob Pan <jacob.jun.pan@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-07-01	tmon: Check log file for common secuirty issues	Neil Horman	1	-0/+24
	The tmon logging system blindly opens its log file on a static path, making it very easy for someone to redirect that log information to inappropriate places or overwrite other users data. Do some easy checking to make sure we're not logging to a symlink or a file owned by another user.

2013-11-07	tools/thermal: Introduce tmon, a tool for thermal subsystem	Jacob Pan	1	-0/+352
	Increasingly, Linux is running on thermally constrained devices. The simple thermal relationship between processor and fan has become past for modern computers. As hardware vendors cope with the thermal constraints on their products, more sensors are added, new cooling capabilities are introduced. The complexity of the thermal relationship can grow exponentially among cooling devices, zones, sensors, and trip points. They can also change dynamically. To expose such relationship to the userspace, Linux generic thermal layer introduced sysfs entry at /sys/class/thermal with a matrix of symbolic links, trip point bindings, and device instances. To traverse such matrix by hand is not a trivial task. Testing is also difficult in that thermal conditions are often exception cases that hard to reach in normal operations. TMON is conceived as a tool to help visualize, tune, and test the complex thermal subsystem. Signed-off-by: Jacob Pan <jacob.jun.pan@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
