NAME

n2cp - Ultra-SPARC T2 crypto provider device driver
 

DESCRIPTION

The n2cp device driver is a multi-threaded, loadable hardware driver supporting hardware-assisted acceleration of the following cryptographic operations, which are built into the Ultra-SPARC T2 CMT processor:

DES:   CKM_DES_CBC, CKM_DES_ECB
DES3:  CKM_DES3_CBC, CKM_DES3_ECB,
AES:   CKM_AES_CBC, CKM_AES_ECB, CKM_AES_CTRB, CKM_AES_CCM
RC4:   CKM_RC4
MD5:   KM_MD5, CKM_MD5_HMAC, CKM_MD5_HMAC_GENERAL, 
            CKM_SSL3_MD5_MAC
SHA-1: CKM_SHA_1, CKM_SHA_1_HMAC, 
       CKM_SHA_1_HMAC_GENERAL, CKM_SSL3_SHA1_MAC
SHA-256:CKM_SHA256, CKM_SHA256_HMAC, 
       CKM_SHA256_HMAC_GENERAL

CONFIGURATION

You configure the n2cp driver by defining properties in the /kernel/drv/n2cp.conf which override the default settings. The following property is supported:

nostats

Disables the generation of statistics. The nostats property may be used to help prevent traffic analysis, however, this may inhibit support personnel.

CRYPTO STATISTICS

Solaris crypto drivers must implement statistics variables. The n2cp driver maintains the following statistics:

cwqXstate

State (online, offline, error) of respective cryptographic engine, CWQ X.

cwqXsubmit

Number of jobs submitted to CWQ X.

cwqXqfull

Number of times when submitting a job that the queue for CWQ X was full.

cwqXqupdate_failure

Number of submit job failures on CWQ X.

des

Total number of jobs submitted to device for DES operations.

des3

Total number of jobs submitted to device for DES3 operations.

aes

Total number of jobs submitted to device for AES operations.

md5

Total number of jobs submitted to device for MD5 operations.

sha1

Total number of jobs submitted to device for SHA-1 operations.

sha256

Total number of jobs submitted to device for SHA-256 operations.

md5hmac

Total number of jobs submitted to device for HMAC_MD5 operations.

sha1hmac

Total number of jobs submitted to device for HMAC_SHA-1 operations.

sha256hmac

Total number of jobs submitted to device for HMAC_SHA-256 operations.

ssl3md5mac

Total number of jobs submitted to device for SSL3_MAC_MD5 operations.

ssl3sha1mac

Total number of jobs submitted to device for SSL3_MAC_SHA-1 operations.

ssl3sha256mac

Total number of jobs submitted to device for SSL3_MAC_SHA-256 operations.

Note -

Additional statistics targeted for Sun support personnel are not documented in this manpage.
