Chapter 16: Function return values and names
Functions can return values of many different kinds, and one of the
most common is a value indicating whether the function succeeded or
failed. Such a value can be represented as an error-code integer
(-Exxx = failure, 0 = success) or a "succeeded" boolean (0 = failure,
non-zero = success).
Mixing up these two sorts of representations is a fertile source of
difficult-to-find bugs. If the C language included a strong distinction
between integers and booleans then the compiler would find these mistakes
for us... but it doesn't. To help prevent such bugs, always follow this
convention:
If the name of a function is an action or an imperative command,
the function should return an error-code integer. If the name
is a predicate, the function should return a "succeeded" boolean.
For example, "add work" is a command, and the add_work() function returns 0
for success or -EBUSY for failure. In the same way, "PCI device present" is
a predicate, and the pci_dev_present() function returns 1 if it succeeds in
finding a matching device or 0 if it doesn't.
All EXPORTed functions must respect this convention, and so should all
public functions. Private (static) functions need not, but it is
recommended that they do.
Functions whose return value is the actual result of a computation, rather
than an indication of whether the computation succeeded, are not subject to
this rule. Generally they indicate failure by returning some out-of-range
result. Typical examples would be functions that return pointers; they use
NULL or the ERR_PTR mechanism to report failure.

This driver implements support for the IT8705F, IT8712F, IT8716F,
IT8718F and SiS950 chips.
These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
joysticks and other miscellaneous stuff. For hardware monitoring, they
include an 'environment controller' with 3 temperature sensors, 3 fan
rotation speed sensors, 8 voltage sensors, and associated alarms.
The IT8712F and IT8716F additionally feature VID inputs, used to report
the Vcore voltage of the processor. The early IT8712F have 5 VID pins,
the IT8716F and late IT8712F have 6. They are shared with other functions
though, so the functionality may not be available on a given system.
The driver dumbly assume it is there.
The IT8718F also features VID inputs (up to 8 pins) but the value is
stored in the Super-I/O configuration space. Due to technical limitations,
this value can currently only be read once at initialization time, so
the driver won't notice and report changes in the VID value. The two
upper VID bits share their pins with voltage inputs (in5 and in6) so you
can't have both on a given board.
The IT8716F, IT8718F and later IT8712F revisions have support for
2 additional fans. They are not yet supported by the driver.
The IT8716F and IT8718F, and late IT8712F and IT8705F also have optional
16-bit tachometer counters for fans 1 to 3. This is better (no more fan
clock divider mess) but not compatible with the older chips and
revisions. For now, the driver only uses the 16-bit mode on the
IT8716F and IT8718F.
Temperatures are measured in degrees Celsius. An alarm is triggered once
when the Overtemperature Shutdown limit is crossed.
Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
triggered if the rotation speed has dropped below a programmable limit. Fan
readings can be divided by a programmable divider (1, 2, 4 or 8) to give the
readings more range or accuracy. Not all RPM values can accurately be

Kernel driver k8temp

* AMD K8 CPU
Prefix: 'k8temp'
Addresses scanned: PCI space
Datasheet: http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/32559.pdf
Author: Rudolf Marek
Contact: Rudolf Marek <r.marek@sh.cvut.cz>
Description
-----------
This driver permits reading temperature sensor(s) embedded inside AMD K8 CPUs.
Official documentation says that it works from revision F of K8 core, but
in fact it seems to be implemented for all revisions of K8 except the first
two revisions (SH-B0 and SH-B3).
There can be up to four temperature sensors inside single CPU. The driver
will auto-detect the sensors and will display only temperatures from
implemented sensors.
Mapping of /sys files is as follows:
temp1_input - temperature of Core 0 and "place" 0
temp2_input - temperature of Core 0 and "place" 1
temp3_input - temperature of Core 1 and "place" 0
temp4_input - temperature of Core 1 and "place" 1
Temperatures are measured in degrees Celsius and measurement resolution is
1 degree C. It is expected that future CPU will have better resolution. The
temperature is updated once a second. Valid temperatures are from -49 to
206 degrees C.
Temperature known as TCaseMax was specified for processors up to revision E.
This temperature is defined as temperature between heat-spreader and CPU
case, so the internal CPU temperature supplied by this driver can be higher.
There is no easy way how to measure the temperature which will correlate
with TCaseMax temperature.
For newer revisions of CPU (rev F, socket AM2) there is a mathematically
computed temperature called TControl, which must be lower than TControlMax.
The relationship is following:
temp1_input - TjOffset*2 < TControlMax,
TjOffset is not yet exported by the driver, TControlMax is usually
70 degrees C. The rule of the thumb -> CPU temperature should not cross
60 degrees C too much.

Prefix: 'vt1211'
Addresses scanned: none, address read from Super-I/O config space
Datasheet: Provided by VIA upon request and under NDA
Authors: Juerg Haefliger <juergh@gmail.com>
This driver is based on the driver for kernel 2.4 by Mark D. Studebaker and
its port to kernel 2.6 by Lars Ekman.
Thanks to Joseph Chan and Fiona Gatt from VIA for providing documentation and
technical support.
Module Parameters
-----------------
* uch_config: int Override the BIOS default universal channel (UCH)
configuration for channels 1-5.
Legal values are in the range of 0-31. Bit 0 maps to
UCH1, bit 1 maps to UCH2 and so on. Setting a bit to 1
enables the thermal input of that particular UCH and
setting a bit to 0 enables the voltage input.
* int_mode: int Override the BIOS default temperature interrupt mode.
The only possible value is 0 which forces interrupt
mode 0. In this mode, any pending interrupt is cleared
when the status register is read but is regenerated as
long as the temperature stays above the hysteresis
limit.
Be aware that overriding BIOS defaults might cause some unwanted side effects!
Description
-----------
The VIA VT1211 Super-I/O chip includes complete hardware monitoring
capabilities. It monitors 2 dedicated temperature sensor inputs (temp1 and
temp2), 1 dedicated voltage (in5) and 2 fans. Additionally, the chip
implements 5 universal input channels (UCH1-5) that can be individually
programmed to either monitor a voltage or a temperature.
This chip also provides manual and automatic control of fan speeds (according
to the datasheet). The driver only supports automatic control since the manual
mode doesn't seem to work as advertised in the datasheet. In fact I couldn't
get manual mode to work at all! Be aware that automatic mode hasn't been
tested very well (due to the fact that my EPIA M10000 doesn't have the fans
connected to the PWM outputs of the VT1211 :-().
The following table shows the relationship between the vt1211 inputs and the
sysfs nodes.

Voltage Monitoring
------------------
Voltages are sampled by an 8-bit ADC with a LSB of ~10mV. The supported input
range is thus from 0 to 2.60V. Voltage values outside of this range need
external scaling resistors. This external scaling needs to be compensated for
via compute lines in sensors.conf, like:
compute inx @*(1+R1/R2), @/(1+R1/R2)
The board level scaling resistors according to VIA's recommendation are as
follows. And this is of course totally dependent on the actual board
implementation :-) You will have to find documentation for your own
motherboard and edit sensors.conf accordingly.

(2) R1 and R2 for 3.3V (int) are internal to the VT1211 chip and the driver
performs the scaling and returns the properly scaled voltage value.
Each measured voltage has an associated low and high limit which triggers an
alarm when crossed.
Temperature Monitoring
----------------------
Temperatures are reported in millidegree Celsius. Each measured temperature
has a high limit which triggers an alarm if crossed. There is an associated
hysteresis value with each temperature below which the temperature has to drop
before the alarm is cleared (this is only true for interrupt mode 0). The
interrupt mode can be forced to 0 in case the BIOS doesn't do it
automatically. See the 'Module Parameters' section for details.
All temperature channels except temp2 are external. Temp2 is the VT1211
internal thermal diode and the driver does all the scaling for temp2 and
returns the temperature in millidegree Celsius. For the external channels
temp1 and temp3-temp7, scaling depends on the board implementation and needs
to be performed in userspace via sensors.conf.
Temp1 is an Intel-type thermal diode which requires the following formula to
convert between sysfs readings and real temperatures:
compute temp1 (@-Offset)/Gain, (@*Gain)+Offset
According to the VIA VT1211 BIOS porting guide, the following gain and offset
values should be used:
Diode Type Offset Gain
---------- ------ ----
Intel CPU 88.638 0.9528
65.000 0.9686 *)
VIA C3 Ezra 83.869 0.9528
VIA C3 Ezra-T 73.869 0.9528
*) This is the formula from the lm_sensors 2.10.0 sensors.conf file. I don't
know where it comes from or how it was derived, it's just listed here for
completeness.
Temp3-temp7 support NTC thermistors. For these channels, the driver returns
the voltages as seen at the individual pins of UCH1-UCH5. The voltage at the
pin (Vpin) is formed by a voltage divider made of the thermistor (Rth) and a
scaling resistor (Rs):
Vpin = 2200 * Rth / (Rs + Rth) (2200 is the ADC max limit of 2200 mV)
The equation for the thermistor is as follows (google it if you want to know
more about it):
Rth = Ro * exp(B * (1 / T - 1 / To)) (To is 298.15K (25C) and Ro is the
nominal resistance at 25C)
Mingling the above two equations and assuming Rs = Ro and B = 3435 yields the
following formula for sensors.conf:
compute tempx 1 / (1 / 298.15 - (` (2200 / @ - 1)) / 3435) - 273.15,
2200 / (1 + (^ (3435 / 298.15 - 3435 / (273.15 + @))))
Fan Speed Control
-----------------
The VT1211 provides 2 programmable PWM outputs to control the speeds of 2
fans. Writing a 2 to any of the two pwm[1-2]_enable sysfs nodes will put the
PWM controller in automatic mode. There is only a single controller that
controls both PWM outputs but each PWM output can be individually enabled and
disabled.
Each PWM has 4 associated distinct output duty-cycles: full, high, low and
off. Full and off are internally hard-wired to 255 (100%) and 0 (0%),
respectively. High and low can be programmed via
pwm[1-2]_auto_point[2-3]_pwm. Each PWM output can be associated with a
different thermal input but - and here's the weird part - only one set of
thermal thresholds exist that controls both PWMs output duty-cycles. The
thermal thresholds are accessible via pwm[1-2]_auto_point[1-4]_temp. Note
that even though there are 2 sets of 4 auto points each, they map to the same
registers in the VT1211 and programming one set is sufficient (actually only
the first set pwm1_auto_point[1-4]_temp is writable, the second set is
read-only).
PWM Auto Point PWM Output Duty-Cycle
------------------------------------------------
pwm[1-2]_auto_point4_pwm full speed duty-cycle (hard-wired to 255)
pwm[1-2]_auto_point3_pwm high speed duty-cycle
pwm[1-2]_auto_point2_pwm low speed duty-cycle
pwm[1-2]_auto_point1_pwm off duty-cycle (hard-wired to 0)

pwm[1-2]_auto_point3_temp high speed temp
pwm[1-2]_auto_point2_temp low speed temp

Long story short, the controller implements the following algorithm to set the
PWM output duty-cycle based on the input temperature:

Description
-----------
This driver implements support for the Winbond W83627EHF and W83627EHG
super I/O chips. We will refer to them collectively as Winbond chips.
The chips implement three temperature sensors, five fan rotation
speed sensors, ten analog voltage sensors, alarms with beep warnings (control
unimplemented), and some automatic fan regulation strategies (plus manual
fan control mode).
Temperatures are measured in degrees Celsius and measurement resolution is 1
degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
the temperature gets higher than high limit; it stays on until the temperature
falls below the Hysteresis value.
Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
triggered if the rotation speed has dropped below a programmable limit. Fan
readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
128) to give the readings more range or accuracy. The driver sets the most
suitable fan divisor itself. Some fans might not be present because they
share pins with other functions.
Voltage sensors (also known as IN sensors) report their values in millivolts.
An alarm is triggered if the voltage has crossed a programmable minimum
or maximum limit.
The driver supports automatic fan control mode known as Thermal Cruise.
In this mode, the chip attempts to keep the measured temperature in a
predefined temperature range. If the temperature goes out of range, fan
is driven slower/faster to reach the predefined range again.
The mode works for fan1-fan4. Mapping of temperatures to pwm outputs is as
follows:
temp1 -> pwm1
temp2 -> pwm2
temp3 -> pwm3
prog -> pwm4 (the programmable setting is not supported by the driver)
/sys files
----------
pwm[1-4] - this file stores PWM duty cycle or DC value (fan speed) in range:
0 (stop) to 255 (full)
pwm[1-4]_enable - this file controls mode of fan/temperature control:
* 1 Manual Mode, write to pwm file any value 0-255 (full speed)
* 2 Thermal Cruise
Thermal Cruise mode
-------------------
If the temperature is in the range defined by:
pwm[1-4]_target - set target temperature, unit millidegree Celcius
(range 0 - 127000)
pwm[1-4]_tolerance - tolerance, unit millidegree Celcius (range 0 - 15000)
there are no changes to fan speed. Once the temperature leaves the interval,
fan speed increases (temp is higher) or decreases if lower than desired.
There are defined steps and times, but not exported by the driver yet.
pwm[1-4]_min_output - minimum fan speed (range 1 - 255), when the temperature
is below defined range.
pwm[1-4]_stop_time - how many milliseconds [ms] must elapse to switch
corresponding fan off. (when the temperature was below
defined range).
Note: last two functions are influenced by other control bits, not yet exported
by the driver, so a change might not have any effect.

BSD Secure Levels Linux Security Module
Michael A. Halcrow <mike@halcrow.us>
Introduction
Under the BSD Secure Levels security model, sets of policies are
associated with levels. Levels range from -1 to 2, with -1 being the
weakest and 2 being the strongest. These security policies are
enforced at the kernel level, so not even the superuser is able to
disable or circumvent them. This hardens the machine against attackers
who gain root access to the system.
Levels and Policies
Level -1 (Permanently Insecure):
- Cannot increase the secure level
Level 0 (Insecure):
- Cannot ptrace the init process
Level 1 (Default):
- /dev/mem and /dev/kmem are read-only
- IMMUTABLE and APPEND extended attributes, if set, may not be unset
- Cannot load or unload kernel modules
- Cannot write directly to a mounted block device
- Cannot perform raw I/O operations
- Cannot perform network administrative tasks
- Cannot setuid any file
Level 2 (Secure):
- Cannot decrement the system time
- Cannot write to any block device, whether mounted or not
- Cannot unmount any mounted filesystems
Compilation
To compile the BSD Secure Levels LSM, seclvl.ko, enable the
SECURITY_SECLVL configuration option. This is found under Security
options -> BSD Secure Levels in the kernel configuration menu.
Basic Usage
Once the machine is in a running state, with all the necessary modules
loaded and all the filesystems mounted, you can load the seclvl.ko
module:
# insmod seclvl.ko
The module defaults to secure level 1, except when compiled directly
into the kernel, in which case it defaults to secure level 0. To raise
the secure level to 2, the administrator writes ``2'' to the
seclvl/seclvl file under the sysfs mount point (assumed to be /sys in
these examples):
# echo -n "2" > /sys/seclvl/seclvl
Alternatively, you can initialize the module at secure level 2 with
the initlvl module parameter:
# insmod seclvl.ko initlvl=2
At this point, it is impossible to remove the module or reduce the
secure level. If the administrator wishes to have the option of doing
so, he must provide a module parameter, sha1_passwd, that specifies
the SHA1 hash of the password that can be used to reduce the secure
level to 0.
To generate this SHA1 hash, the administrator can use OpenSSL:
# echo -n "boogabooga" | openssl sha1
abeda4e0f33defa51741217592bf595efb8d289c
In order to use password-instigated secure level reduction, the SHA1
crypto module must be loaded or compiled into the kernel:
# insmod sha1.ko
The administrator can then insmod the seclvl module, including the
SHA1 hash of the password:
# insmod seclvl.ko
sha1_passwd=abeda4e0f33defa51741217592bf595efb8d289c
To reduce the secure level, write the password to seclvl/passwd under
your sysfs mount point:
# echo -n "boogabooga" > /sys/seclvl/passwd
The September 2004 edition of Sys Admin Magazine has an article about
the BSD Secure Levels LSM. I encourage you to refer to that article
for a more in-depth treatment of this security module:
