2018-01-19mm: larger stack guard gap, between vmasSri Krishna chowdary
commit 1be7107fbe18eed3e319a6c3e83c78254b693acb upstream. Stack guard page is a useful feature to reduce a risk of stack smashing into a different mapping. We have been using a single page gap which is sufficient to prevent having stack adjacent to a different mapping. But this seems to be insufficient in the light of the stack usage in userspace. E.g. glibc uses as large as 64kB alloca() in many commonly used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX] which is 256kB or stack strings with MAX_ARG_STRLEN. This will become especially dangerous for suid binaries and the default no limit for the stack size limit because those applications can be tricked to consume a large portion of the stack and a single glibc call could jump over the guard page. These attacks are not theoretical, unfortunatelly. Make those attacks less probable by increasing the stack guard gap to 1MB (on systems with 4k pages; but make it depend on the page size because systems with larger base pages might cap stack allocations in the PAGE_SIZE units) which should cover larger alloca() and VLA stack allocations. It is obviously not a full fix because the problem is somehow inherent, but it should reduce attack space a lot. One could argue that the gap size should be configurable from userspace, but that can be done later when somebody finds that the new 1MB is wrong for some special case applications. For now, add a kernel command line option (stack_guard_gap) to specify the stack gap size (in page units). Implementation wise, first delete all the old code for stack guard page: because although we could get away with accounting one extra page in a stack vma, accounting a larger gap can break userspace - case in point, a program run with "ulimit -S -v 20000" failed when the 1MB gap was counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK and strict non-overcommit mode. Instead of keeping gap inside the stack vma, maintain the stack guard gap as a gap between vmas: using vm_start_gap() in place of vm_start (or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few places which need to respect the gap - mainly arch_get_unmapped_area(), and and the vma tree's subtree_gap support for that.

The m41t0 variant is very similar to the already supported m41t00 variant, with the notable exception of the oscillator fail bit. The data sheet notes: If the oscillator fail (OF) bit is internally set to a '1,' this indicates that the oscillator has either stopped, or was stopped for some period of time and can be used to judge the validity of the clock and date data. The bit will get cleared with a regular write of the system time, so no changes are needed to clear it.

2014-02-27cpufreq: cpufreq-cpu0: add dt node parsing for cooling device propertiesEduardo Valentin
This patch changes the cpufreq-cpu0 driver to consider if a cpu needs cooling (with cpufreq). In case the cooling is needed, the cpu0 device tree node needs to be properly configured with cooling device properties. In case these properties are present,, the driver will load a cpufreq cooling device in the system. The cpufreq-cpu0 driver is not interested in determining how the system should be using the cooling device. The driver is responsible only of loading the cooling device. Describing how the cooling device will be used can be accomplished by setting up a thermal zone that references and is composed by the cpufreq cooling device.

2014-02-27thermal: introduce device tree parserEduardo Valentin
This patch introduces a device tree bindings for describing the hardware thermal behavior and limits. Also a parser to read and interpret the data and feed it in the thermal framework is presented. This patch introduces a thermal data parser for device tree. The parsed data is used to build thermal zones and thermal binding parameters. The output data can then be used to deploy thermal policies. This patch adds also documentation regarding this API and how to define tree nodes to use this infrastructure. Note that, in order to be able to have control on the sensor registration on the DT thermal zone, it was required to allow changing the thermal zone .get_temp callback. For this reason, this patch also removes the 'const' modifier from the .ops field of thermal zone devices.
