2018-10-12Documentation: dt: Add binding for /secure-chosen/stdout-pathJerome Forissier1-1/+18
Some platforms may use a single device tree to describe two address spaces, as described in d9f43babb998 ("Documentation: dt: Add bindings for Secure-only devices"). For these platforms it makes sense to define a secure counterpart of /chosen, namely: /secure-chosen. This new node is meant to be used by the secure firmware to pass data to the secure OS. Only the stdout-path property is supported for now. Signed-off-by: Jerome Forissier <jerome.forissier@linaro.org> Signed-off-by: Rob Herring <robh@kernel.org>

2018-09-27dt-binding: arm/cpus.txt: fix dynamic-power-coefficient unitVincent Guittot1-2/+2
The unit of dynamic-power-coefficient is described as mW/MHz/uV^2 whereas its usage in the code assumes that unit is uW/MHz/V^2 In drivers/thermal/cpu_cooling.c, the code is : power = (u64)capacitance * freq_mhz * voltage_mv * voltage_mv; do_div(power, 1000000000); which can be summarized as : power (mW) = capacitance * freq_mhz/1000 * (voltage_mv/1000)^2 or power (mW) = (capacitance * freq_mhz * (voltage_mv/1000)^2) / 1000 then power (mW) = power (uW) / 1000 so power (uW) = capacitance * freq_mhz * (voltage_mv/1000)^2 Furthermore, if we test basic values like : voltage_mv = 1000mV = 1V freq_mhz = 1000Mhz The minimum possible power, when dynamic-power-coefficient equals 1, will be with current unit: min power = 1 * 1000 * (1000000)^2 = 10^15 mW which is not realistic With the unit used by the code, the min power is min power = 1 * 1000 * 1^2 = 1000uW = 1mW which is far more realistic Signed-off-by: Vincent Guittot <vincent.guittot@linaro.org> Acked-by: Punit Agrawal <punit.agrawal@arm.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rob Herring <robh@kernel.org>

2018-08-24arm64: dts: Fix various entry-method properties to reflect documentationAmit Kucheria2-3/+3
The idle-states binding documentation[1] mentions that the 'entry-method' property is required on 64-bit platforms and must be set to "psci". commit a13f18f59d26 ("Documentation: arm: Fix typo in the idle-states bindings examples") attempted to fix this earlier but clearly more is needed. Fix the cpu-capacity.txt documentation that uses the incorrect value so we don't get copy-paste errors like these. Clarify the language in idle-states.txt by removing the reference to the psci bindings that might be causing this confusion. Finally, fix devicetrees of various boards to reflect current documentation.

2018-08-24treewide: convert ISO_8859-1 text comments to utf-8Arnd Bergmann1-1/+1
Almost all files in the kernel are either plain text or UTF-8 encoded. A couple however are ISO_8859-1, usually just a few characters in a C comments, for historic reasons. This converts them all to UTF-8 for consistency.

2018-08-24namei: allow restricted O_CREAT of FIFOs and regular filesSalvatore Mesoraca1-0/+36
Disallows open of FIFOs or regular files not owned by the user in world writable sticky directories, unless the owner is the same as that of the directory or the file is opened without the O_CREAT flag. The purpose is to make data spoofing attacks harder. This protection can be turned on and off separately for FIFOs and regular files via sysctl, just like the symlinks/hardlinks protection. This patch is based on Openwall's "HARDEN_FIFO" feature by Solar Designer. This is a brief list of old vulnerabilities that could have been prevented by this feature, some of them even allow for privilege escalation: CVE-2000-1134 CVE-2007-3852 CVE-2008-0525 CVE-2009-0416 CVE-2011-4834 CVE-2015-1838 CVE-2015-7442 CVE-2016-7489 This list is not meant to be complete. It's difficult to track down all vulnerabilities of this kind because they were often reported without any mention of this particular attack vector. In fact, before hardlinks/symlinks restrictions, fifos/regular files weren't the favorite vehicle to exploit them.
