n2cp(7d) Devices n2cp(7d)NAMEn2cp - 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 crypto‐
graphic operations, which are built into the Ultra-SPARC T2 CMT proces‐
sor:
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 /plat‐
form/sun4v/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 pre‐
vent 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 respec‐
tive 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 doc‐
umented in this man page.
