First two patches fixes problem with old /proc/i8k file. Second is security fix and should be backported to all stable kernels (that problem was there always). I tested i8kctl tool (from i8kutils package) that it still works with these patches. Without root access for those security operations just showes '?' or '-1'. Third and fourth patches try to fix problem on machines with broken SMM/BIOS when calling function fan_type(). Fifth is new feature and last sixth useful for debugging. Pali Rohár (6): hwmon: (dell-smm) Fail in ioctl I8K_BIOS_VERSION when bios version is not a number hwmon: (dell-smm) Restrict fan control and serial number to CAP_SYS_ADMIN by default hwmon: (dell-smm) Disallow fan_type() calls on broken machines hwmon: (dell-smm) Cache fan_type() calls and change fan detection hwmon: (dell-smm) Detect fan with index=2 hwmon: (dell-smm) In debug mode log duration of SMM calls drivers/hwmon/dell-smm-hwmon.c | 122 ++++++++++++++++++++++++++++++++-------- 1 file changed, 99 insertions(+), 23 deletions(-) -- 1.7.9.5
