SCSI_IOCTL_SEND_COMMAND has been deprecated longer than bsg exists and has been warning for just as long. More importantly it harcodes SCSI CDBs and thus will do the wrong thing on non-SCSI bsg nodes.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. During runtime, driver and authentication application need 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. Link: https://lore.kernel.org/r/20210624052606.21613-9-njavali@marvell.comReviewed-by:

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. There is no FC switch scan service that can indicate whether a device is secure or non-secure. In order to detect whether the remote port supports encrypted operation, driver must first do a PLOGI with the remote device. On completion of the PLOGI, driver will query firmware to see if the device supports secure login. To do that, driver + firmware must advertise the security bit via PLOGI's service parameter. The remote device shall respond using the same service parameter whether it supports it or not. Link: https://lore.kernel.org/r/20210624052606.21613-8-njavali@marvell.comReviewed-by:

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. On completion of the authentication process, the authentication application will notify driver on whether it is successful or not. In case of success, application will use the QL_VND_SC_AUTH_OK BSG call to tell driver to proceed to the PRLI phase. In case of failure, 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 ensures data is not further compromised.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application 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 passed 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. Add a new bsg call (QL_VND_SC_SA_UPDATE) to allow application to allow adding or deleting SADB entries. Driver will not keep the key in memory. It will pass it to HW. It is assumed that application will assign a unique SPI value to this SADB (SA + key). Driver + hardware will assign a handle to track this unique SPI/SADB. Link: https://lore.kernel.org/r/20210624052606.21613-6-njavali@marvell.comReviewed-by:

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. Once authentication messages sent from a remote device have 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.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. Add the ability for authentication application to send and retrieve messages 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.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. Add two new BSG calls: - QL_VND_SC_GET_FCINFO: Application can from time to time request a list of all FC ports or a single device that supports secure connection. If driver sees a new or old device has logged into the switch, this call is used to check for the WWPN. - QL_VND_SC_GET_STATS: Application request for various statistics for each FC port.

For SD card reader devices that have the BLIST_IGN_MEDIA_CHANGE flag set, a MEDIUM MAY HAVE CHANGED unit attention is established after resuming from runtime suspend. Send a REQUEST SENSE to consume the UA. The "downside" is that for these devices we now rely on users to not change the medium (SD card) *during* a runtime suspend/resume cycle, i.e. when not unmounting. To enable runtime PM for an SD cardreader (device number 0:0:0:0), do: echo 0 > /sys/module/block/parameters/events_dfl_poll_msecs echo 1000 > /sys/bus/scsi/devices/0:0:0:0/power/autosuspend_delay_ms echo auto > /sys/bus/scsi/devices/0:0:0:0/power/control [mkp: use scsi_device flag instead of poking at BLIST] Link: https://lore.kernel.org/r/20210704075403.147114-3-martin.kepplinger@puri.smReviewed-by:

It is useful for testing purposes to be able to inject errors by writing bad protection information to media with checking disabled and then attempting to read it back. Extend scsi_debug's PI verification logic to give the driver feature parity with commercially available drives.

The function used to dump sectors containing protection information errors was useful during initial development over a decade ago. However, dump_sector() substantially slows down the system during testing due to writing an entire sector's worth of data to syslog on every error. We now log plenty of information about the nature of detected protection information errors throughout the stack. Dumping the entire contents of an offending sector is no longer needed.
