2016-07-31hwmon: (ftsteutates) Fix potential memory access errorGuenter Roeck1-1/+1
Using set_bit() to set a bit in an integer is not a good idea, since the function expects an unsigned long as argument, which can be 64 bit wide. Coverity reports this problem as >>> CID 1364488: Memory - illegal accesses (INCOMPATIBLE_CAST) >>> Pointer "&ret" points to an object whose effective type is "int" >>> (32 bits, signed) but is dereferenced as a wider "unsigned +long" (64 bits, unsigned). This may lead to memory corruption. 245 set_bit(1, (unsigned long *)&ret); Just use BIT instead.

2016-07-12hwmon: (tmp102) Convert to use regmap, and drop local cacheGuenter Roeck2-78/+71
By converting the driver to regmap, we can use regmap to cache non-volatile registers. Stop caching the temperature register; while potentially reading it more often can result in reading it more often than necessary, this is offset by the gain due to not re-reading the limit registers. A positive side effect of this change is that limit registers can now be read and updated before the first temperature conversion is complete.

2016-07-12hwmon: (tmp102) Rework chip configurationGuenter Roeck1-15/+22
So far the chip was forced into polarity 0, even if it was preconfigured differently. Do not touch the polarity when configuring the chip. Also, the configuration register was read beack to check if the configuration 'sticks'. Ultimately, that is similar to checking if the chip is a tmp102 in the first place. Checking if a write into the configuration register was successful is really not the way to do it, and quite risky if the chip is not a tmp102, so drop that check. Instead, verify if the configuration register has unexpected bits set before writing into it. Acked-by: Nishanth Menon <nm@ti.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-07-12hwmon: (tmp102) Improve handling of initial read delayGuenter Roeck1-14/+30
If the chip was in shutdown mode when the driver was loaded, the first conversion is ready no more than 35 milli-seconds after the chip was taken out of shutdown. The driver delay was so far set to 333 ms (HZ / 3), which is much higher than the maximum time needed by the chip. Reduce the time to 35 milli-seconds. Introduce a 'valid' flag to ensure that sensor data is actually read even if requested less than 333 ms after the driver was loaded.

2016-07-04hwmon: (jc42) Add I2C_CLASS_HWMON to detection classAlison Schofield1-1/+1
In 2011, commit 774466add7c ("hwmon: (jc42) Change detection class") changed the detection class of these chips to I2C_CLASS_SPD based on this premise: "makes more sense because these chips always live on memory modules" Today these chips have applications beyond memory modules. Examples are JC42.4 compatible chips such as MCP9804 and MCP9808, but also MCP9805, which is marked as JC42.4 compliant and suggested for use not only for DIMMS, but also as generic temperature sensor. Add I2C_CLASS_HWMON as an additional detection class to allow detection by hwmon class i2c adapters.

2016-06-23hwmon: (dell-smm) Cache fan_type() calls and change fan detectionPali Rohár1-5/+20
On more Dell machines (e.g. Dell Precision M3800) fan_type() call is too expensive (CPU is too long in SMM mode) and cause kernel to hang. This is bug in Dell SMM or BIOS. This patch caches type for each fan (as it should not change) and changes the way how fan presense is detected. First it try function fan_status() as was before commit f989e55452c7 ("i8k: Add support for fan labels"). And if that fails fallback to fan_type(). *_status() functions can fail in case fan is not currently accessible (e.g. present on GPU which is currently turned off).

2016-06-18hwmon: (dell-smm) Disallow fan_type() calls on broken machinesPali Rohár1-11/+25
Some Dell machines have especially broken SMM or BIOS which cause that once fan_type() is called then CPU fan speed going randomly up and down. And for fixing this behaviour reboot is required. So this patch creates fan_type blacklist of affected Dell machines and disallow fan_type() call on them to prevent that erratic behaviour. Old blacklist which disabled loading driver on some machines added in commits a4b45b25f18d ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100") and 6220f4ebd7b4 ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8000") were moved to FAN_TYPE blacklist.

2016-06-18hwmon: (dell-smm) Restrict fan control and serial number to CAP_SYS_ADMIN by defaultPali Rohár1-7/+12
For security reasons ordinary user must not be able to control fan speed via /proc/i8k by default. Some malicious software running under "nobody" user could be able to turn fan off and cause HW problems. So this patch changes default value of "restricted" parameter to 1. Also restrict reading of DMI_PRODUCT_SERIAL from /proc/i8k via "restricted" parameter. It is because non root user cannot read DMI_PRODUCT_SERIAL from sysfs file /sys/class/dmi/id/product_serial. Old non secure behaviour of file /proc/i8k can be achieved by loading this module with "restricted" parameter set to 0. Note that this patch has effects only for kernels compiled with CONFIG_I8K and only for file /proc/i8k. Hwmon interface provided by this driver was not changed and root access for setting fan speed was needed also before.
