What: /sys/kernel/debug/nx-crypto/* | ||
Date: March 2012 | ||
KernelVersion: 3.4 | ||
Contact: Kent Yoder <[email protected]> | ||
Description: | ||
|
||
These debugfs interfaces are built by the nx-crypto driver, built in | ||
arch/powerpc/crypto/nx. | ||
|
||
Error Detection | ||
=============== | ||
|
||
errors: | ||
- A u32 providing a total count of errors since the driver was loaded. The | ||
only errors counted here are those returned from the hcall, H_COP_OP. | ||
|
||
last_error: | ||
- The most recent non-zero return code from the H_COP_OP hcall. -EBUSY is not | ||
recorded here (the hcall will retry until -EBUSY goes away). | ||
|
||
last_error_pid: | ||
- The process ID of the process who received the most recent error from the | ||
hcall. | ||
|
||
Device Use | ||
========== | ||
|
||
aes_bytes: | ||
- The total number of bytes encrypted using AES in any of the driver's | ||
supported modes. | ||
|
||
aes_ops: | ||
- The total number of AES operations submitted to the hardware. | ||
|
||
sha256_bytes: | ||
- The total number of bytes hashed by the hardware using SHA-256. | ||
|
||
sha256_ops: | ||
- The total number of SHA-256 operations submitted to the hardware. | ||
|
||
sha512_bytes: | ||
- The total number of bytes hashed by the hardware using SHA-512. | ||
|
||
sha512_ops: | ||
- The total number of SHA-512 operations submitted to the hardware. |

What: /dev/kmsg | ||
Date: Mai 2012 | ||
KernelVersion: 3.5 | ||
Contact: Kay Sievers <[email protected]> | ||
Description: The /dev/kmsg character device node provides userspace access | ||
to the kernel's printk buffer. | ||
|
||
Injecting messages: | ||
Every write() to the opened device node places a log entry in | ||
the kernel's printk buffer. | ||
|
||
The logged line can be prefixed with a <N> syslog prefix, which | ||
carries the syslog priority and facility. The single decimal | ||
prefix number is composed of the 3 lowest bits being the syslog | ||
priority and the higher bits the syslog facility number. | ||
|
||
If no prefix is given, the priority number is the default kernel | ||
log priority and the facility number is set to LOG_USER (1). It | ||
is not possible to inject messages from userspace with the | ||
facility number LOG_KERN (0), to make sure that the origin of | ||
the messages can always be reliably determined. | ||
|
||
Accessing the buffer: | ||
Every read() from the opened device node receives one record | ||
of the kernel's printk buffer. | ||
|
||
The first read() directly following an open() always returns | ||
first message in the buffer; there is no kernel-internal | ||
persistent state; many readers can concurrently open the device | ||
and read from it, without affecting other readers. | ||
|
||
Every read() will receive the next available record. If no more | ||
records are available read() will block, or if O_NONBLOCK is | ||
used -EAGAIN returned. | ||
|
||
Messages in the record ring buffer get overwritten as whole, | ||
there are never partial messages received by read(). | ||
|
||
In case messages get overwritten in the circular buffer while | ||
the device is kept open, the next read() will return -EPIPE, | ||
and the seek position be updated to the next available record. | ||
Subsequent reads() will return available records again. | ||
|
||
Unlike the classic syslog() interface, the 64 bit record | ||
sequence numbers allow to calculate the amount of lost | ||
messages, in case the buffer gets overwritten. And they allow | ||
to reconnect to the buffer and reconstruct the read position | ||
if needed, without limiting the interface to a single reader. | ||
|
||
The device supports seek with the following parameters: | ||
SEEK_SET, 0 | ||
seek to the first entry in the buffer | ||
SEEK_END, 0 | ||
seek after the last entry in the buffer | ||
SEEK_DATA, 0 | ||
seek after the last record available at the time | ||
the last SYSLOG_ACTION_CLEAR was issued. | ||
|
||
The output format consists of a prefix carrying the syslog | ||
prefix including priority and facility, the 64 bit message | ||
sequence number and the monotonic timestamp in microseconds. | ||
The values are separated by a ','. Future extensions might | ||
add more comma separated values before the terminating ';'. | ||
Unknown values should be gracefully ignored. | ||
|
||
The human readable text string starts directly after the ';' | ||
and is terminated by a '\n'. Untrusted values derived from | ||
hardware or other facilities are printed, therefore | ||
all non-printable characters in the log message are escaped | ||
by "\x00" C-style hex encoding. | ||
|
||
A line starting with ' ', is a continuation line, adding | ||
key/value pairs to the log message, which provide the machine | ||
readable context of the message, for reliable processing in | ||
userspace. | ||
|
||
Example: | ||
7,160,424069;pci_root PNP0A03:00: host bridge window [io 0x0000-0x0cf7] (ignored) | ||
SUBSYSTEM=acpi | ||
DEVICE=+acpi:PNP0A03:00 | ||
6,339,5140900;NET: Registered protocol family 10 | ||
30,340,5690716;udevd[80]: starting version 181 | ||
|
||
The DEVICE= key uniquely identifies devices the following way: | ||
b12:8 - block dev_t | ||
c127:3 - char dev_t | ||
n8 - netdev ifindex | ||
+sound:card0 - subsystem:devname | ||

Date: March 2012 | ||
KernelVersion: TBD | ||
Contact: Robert Love <[email protected]>, [email protected] | ||
Description: 'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel | ||
Forwarder, which is a FCoE switch that can accept FCoE | ||
(Ethernet) packets, unpack them, and forward the embedded | ||
Fibre Channel frames into a FC fabric. It can also take | ||
outbound FC frames and pack them in Ethernet packets to | ||
be sent to their destination on the Ethernet segment. | ||
Attributes: | ||
|
||
fabric_name: Identifies the fabric that the FCF services. | ||
|
||
switch_name: Identifies the FCF. | ||
|
||
priority: The switch's priority amongst other FCFs on the same | ||
fabric. | ||
|
||
selected: 1 indicates that the switch has been selected for use; | ||
0 indicates that the swich will not be used. | ||
|
||
fc_map: The Fibre Channel MAP | ||
|
||
vfid: The Virtual Fabric ID | ||
|
||
mac: The FCF's MAC address | ||
|
||
fka_peroid: The FIP Keep-Alive peroid | ||
|
||
fabric_state: The internal kernel state | ||
"Unknown" - Initialization value | ||
"Disconnected" - No link to the FCF/fabric | ||
"Connected" - Host is connected to the FCF | ||
"Deleted" - FCF is being removed from the system | ||
|
||
dev_loss_tmo: The device loss timeout peroid for this FCF. | ||
|
||
Notes: A device loss infrastructre similar to the FC Transport's | ||
is present in fcoe_sysfs. It is nice to have so that a | ||
link flapping adapter doesn't continually advance the count | ||
used to identify the discovered FCF. FCFs will exist in a | ||
"Disconnected" state until either the timer expires and the | ||
FCF becomes "Deleted" or the FCF is rediscovered and becomes | ||
"Connected." | ||
|
||
|
||
Users: The first user of this interface will be the fcoeadm application, | ||
which is commonly packaged in the fcoe-utils package. |
