1What: security/evm
2Date: March 2011
3Contact: Mimi Zohar <zohar@us.ibm.com>
4Description:
5 EVM protects a file's security extended attributes(xattrs)
6 against integrity attacks. The initial method maintains an
7 HMAC-sha1 value across the extended attributes, storing the
8 value as the extended attribute 'security.evm'.
9
10 EVM depends on the Kernel Key Retention System to provide it
11 with a trusted/encrypted key for the HMAC-sha1 operation.
12 The key is loaded onto the root's keyring using keyctl. Until
13 EVM receives notification that the key has been successfully
14 loaded onto the keyring (echo 1 > <securityfs>/evm), EVM
15 can not create or validate the 'security.evm' xattr, but
16 returns INTEGRITY_UNKNOWN. Loading the key and signaling EVM
17 should be done as early as possible. Normally this is done
18 in the initramfs, which has already been measured as part
19 of the trusted boot. For more information on creating and
20 loading existing trusted/encrypted keys, refer to:
21 Documentation/keys-trusted-encrypted.txt. (A sample dracut
22 patch, which loads the trusted/encrypted key and enables
23 EVM, is available from http://linux-ima.sourceforge.net/#EVM.)

212Description:
213 A raw device name of a disk does not always point a same disk
214 each boot-up time. Therefore, users have to use persistent

3Date: January 2007
4KernelVersion: 2.6.21
5Contact: Alan Stern <stern@rowland.harvard.edu>
6Description:
7 PCI-based EHCI USB controllers (i.e., high-speed USB-2.0
8 controllers) are often implemented along with a set of
9 "companion" full/low-speed USB-1.1 controllers. When a
10 high-speed device is plugged in, the connection is routed
11 to the EHCI controller; when a full- or low-speed device
12 is plugged in, the connection is routed to the companion
13 controller.
14
15 Sometimes you want to force a high-speed device to connect
16 at full speed, which can be accomplished by forcing the
17 connection to be routed to the companion controller.
18 That's what this file does. Writing a port number to the
19 file causes connections on that port to be routed to the
20 companion controller, and writing the negative of a port
21 number returns the port to normal operation.
22
23 For example: To force the high-speed device attached to
24 port 4 on bus 2 to run at full speed:
25
26 echo 4 >/sys/bus/usb/devices/usb2/../companion
27
28 To return the port to high-speed operation:
29
30 echo -4 >/sys/bus/usb/devices/usb2/../companion
31
32 Reading the file gives the list of ports currently forced
33 to the companion controller.
34
35 Note: Some EHCI controllers do not have companions; they
36 may contain an internal "transaction translator" or they
37 may be attached directly to a "rate-matching hub". This
38 mechanism will not work with such controllers. Also, it
39 cannot be used to force a port on a high-speed hub to
40 connect at full speed.
41
42 Note: When this file was first added, it appeared in a
43 different sysfs directory. The location given above is
44 correct for 2.6.35 (and probably several earlier kernel
45 versions as well).

5Description:
6 The /sys/class/hidraw/hidraw*/device/speed file controls
7 reporting speed of Wacom bluetooth tablet. Reading from
8 this file returns 1 if tablet reports in high speed mode
9 or 0 otherwise. Writing to this file one of these values
10 switches reporting speed.

15Description:
16 Attribute group for control of the status LEDs and the OLEDs.
17 This attribute group is only available for Intuos 4 M, L,
18 and XL (with LEDs and OLEDs) and Cintiq 21UX2 (LEDs only).
19 Therefore its presence implicitly signifies the presence of
20 said LEDs and OLEDs on the tablet device.

25Description:
26 Writing to this file sets the status LED luminance (1..127)
27 when the stylus does not touch the tablet surface, and no
28 button is pressed on the stylus. This luminance level is
29 normally lower than the level when a button is pressed.

65Description:
66 When writing a 1024 byte raw image in Wacom Intuos 4
67 interleaving format to the file, the image shows up on Button N
68 of the device. The image is a 64x32 pixel 4-bit gray image. The
69 1024 byte binary is split up into 16x 64 byte chunks. Each 64
70 byte chunk encodes the image data for two consecutive lines on
71 the display. The low nibble of each byte contains the first
72 line, and the high nibble contains the second line.
