s390/qdio: remove cdev from init_data

s390/qdio: allow for non-contiguous SBAL array in init_data

2020-04-06T11:13:50Z

Upper-layer drivers allocate their SBALs by calling qdio_alloc_buffers() for each individual queue. But when later passing the SBAL addresses to qdio_establish(), they need to be in a single array of pointers. So if the driver uses multiple Input or Output queues, it needs to allocate a temporary array just to present all its SBAL pointers in this layout. This patch slightly changes the format of the QDIO initialization data, so that drivers can pass a per-queue array where each element points to a queue's SBAL array. zfcp doesn't use multiple queues, so the impact there is trivial. For qeth this brings a nice reduction in complexity, and removes a page-sized allocation. Signed-off-by: Julian Wiedmann Reviewed-by: Benjamin Block Signed-off-by: Vasily Gorbik

s390/qdio: cleanly split alloc and establish

2020-04-06T11:13:50Z

All that qdio_allocate() actually uses from the init_data is the cdev, and the number of Input and Output Queues. Have the driver pass those as parameters, and defer the init_data processing into qdio_establish(). This includes writing per-device(!) trace entries, and most of the sanity checks.

Enable for explicit FCP channel FC Endpoint Security error reporting and handle any FSF security errors according to specification. Take the following recovery actions when a FSF_SECURITY_ERROR is reported for the specified FSF commands: - Open Port: Retry the command if possible - Send FCP : Physically close the remote port and reopen For Open Port the command status is set to error, which triggers a retry. For Send FCP the command status is set to error and recovery is triggered to physically reopen the remote port.

scsi: zfcp: trace FC Endpoint Security of FCP devices and connections

2020-03-17T17:12:40Z

Trace changes in Fibre Channel Endpoint Security capabilities of FCP devices as well as changes in Fibre Channel Endpoint Security state of their connections to FC remote ports as FC Endpoint Security changes with trace level 3 in HBA DBF. A change in FC Endpoint Security capabilities of FCP devices is traced as response to FSF command FSF_QTCB_EXCHANGE_PORT_DATA with a trace tag of "fsfcesa" and a WWPN of ZFCP_DBF_INVALID_WWPN = 0x0000000000000000 (see FC-FS-4 §18 "Name_Identifier Formats", NAA field). A change in FC Endpoint Security state of connections between FCP devices and FC remote ports is traced as response to FSF command FSF_QTCB_OPEN_PORT_WITH_DID with a trace tag of "fsfcesp".
