Martin,
Please apply the EDIF support feature to the scsi tree at your earliest
convenience.
v4:
Reword subject line for patch 10/11.
v3:
- Incorporate the review comments.
- Enable recently added heartbeat validation for EDIF.
v2:
Split the EDIF support feature into logical commits for better readability.
Thanks,
Nilesh

From: Quinn Tran <qutran@marvell.com>
Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
This patch add 2 new BSG calls:
QL_VND_SC_APP_START: application will announce its present
to driver with this call. Driver will restart all
connections to see if remote device support security or not.
QL_VND_SC_APP_STOP: application announce it's in the process
of exiting. Driver will restart all connections to revert
back to non-secure. Provided the remote device is willing
to allow a non-secure connection.

To: martin.petersen; +Cc: linux-scsi, GR-QLogic-Storage-Upstream
From: Quinn Tran <qutran@marvell.com>
Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
This patch add 2 new BSG calls:
QL_VND_SC_GET_FCINFO: Application from time to time can request
for a list of all FC ports or a single device that support
secure connection. If driver sees a new or old device has
came onto the switch, this call is used to check for the WWPN.
QL_VND_SC_GET_STATS: Application request for various statistic
count of each FC port.

To: martin.petersen; +Cc: linux-scsi, GR-QLogic-Storage-Upstream
From: Quinn Tran <qutran@marvell.com>
Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
This patch add ability for authentication application to
send and retrieve message(s) as part of the authentication
process via existing FC_BSG_HST_ELS_NOLOGIN BSG interface
To send a message, application is expected to format the
data in the AUTH ELS format. Refer to FC-SP2 for details.
If a message was received, application is required to reply with
either a LS_ACC or LS_RJT complete the exchange using the same
interface. Otherwise, remote device will treat it as a
timeout.

To: martin.petersen; +Cc: linux-scsi, GR-QLogic-Storage-Upstream
From: Quinn Tran <qutran@marvell.com>
Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
This patch is a continuation of previous patch where
authentication messages sent from remote device has arrived.
Each message is extracted and placed in a buffer for application
to retrieve. The FC frame header will be stripped leaving
behind the AUTH ELS payload. It is up to the application
to strip the AUTH ELS header to get to the actual authentication
message.

From: Nilesh Javali @ 2021-06-24 5:26 UTC (permalink / raw)
To: martin.petersen; +Cc: linux-scsi, GR-QLogic-Storage-Upstream
From: Quinn Tran <qutran@marvell.com>
Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
As part of the authentication process, the authentication
application will generate a SADB entry (Security Association/SA,
key, SPI value, etc). This SADB is then pass to driver
to be programmed into hardware. There will be a pair of
SADB's (Tx and Rx) for each connection.
After some period, the application can choose to change the
key. At that time, a new set of SADB pair is given to driver.
The old set of SADB will be deleted.
This patch add a new bsg call (QL_VND_SC_SA_UPDATE) to allow
application to allow add | delete of SADB. Driver will not
keep the key in memory. It will pass it to HW.
It is assume that application will assign a unique SPI value
to this SADB(SA + key). Driver + HW will assign a handle
to track this unique SPI/SADB.

Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
On completion of the authentication process, the authentication
application will notify driver on whether it is successful or not.
If success, application will use the QL_VND_SC_AUTH_OK BSG call
to tell driver to proceed to the PRLI phase.
If fail, application will use the QL_VND_SC_AUTH_FAIL bsg call
to tell driver to tear down the connection and retry. In
the case where an existing session is active, the re-key
process can fail. The session tear down ensure data is not
further compromise.

Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
At this time, there is no FC switch scan service that
indicate a device is secure or non-secure.
In order to detect whether the remote port support secured
or not, driver must first do a PLOGI with the remote device.
On completion of the PLOGI, driver will query FW to see if
the device supports secure login. To do that, driver + FW
must advertise the security bit via PLOGI's service
parameter. The remote device shall respond with the same
service parameter bit on whether it supports it or not.

To: martin.petersen; +Cc: linux-scsi, GR-QLogic-Storage-Upstream
From: Quinn Tran <qutran@marvell.com>
Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
During runtime, driver and authentication application needs
to stay in sync in terms of: session being down|up, arrival of
new authentication message(AUTH ELS) and SADB update completion.
These events are queued up as doorbell to the authentication
application. Application would read this doorbell on regular
basis to stay up to date. Each SCSI host would have a separate
doorbell queue.
The doorbell interface can daisy chain a list of events for
each read. Each event contains an event code + hint to help
application steer the next course of action.

From: Nilesh Javali @ 2021-06-24 5:26 UTC (permalink / raw)
To: martin.petersen; +Cc: linux-scsi, GR-QLogic-Storage-Upstream
From: Quinn Tran <qutran@marvell.com>
Latest FC adapter from Marvell has the ability to encrypt
data in flight (EDIF) feature. This feature require an
application (ex: ipsec, etc) to act as an authenticator.
After the completion of PLOGI, both sides have authenticated
and PRLI completion, encrypted IOs are allow to proceed.
This patch adds the following:
- use new FW api to encrypt traffic on the wire.
- add driver parameter to enable|disable EDIF feature.
