When a switch disable/enable or a reboot is done, the HBA port gets an offline and a subsequent online notification. When the port comes up a link up notification is sent to bfa from the firmware. The bfa then send an FLOGI to the firmware which is sent out on the wire. The switch port meanwhile goes offline (presumably for diagnostics) which causes the switch not to respond to the FLOGI. The link down notification is sent to the HBA driver. However owing to a bug in the lps state machine handling the lps state machine does not move to sm_init state (it remains in sm_login state and send a login complete message to fcs). This results in a zero PID assignment as the login is not really complete. This fix is to correctly handle the events in lps state machine.

Introduce eh_timeout which can be used for error handling purposes. This was previously hardcoded to 10 seconds in the SCSI error handling code. However, for some fast-fail scenarios it is necessary to be able to tune this as it can take several iterations (bus device, target, bus, controller) before we give up. Signed-off-by: NMartin K.

When multipathed systems run into an all-paths-down scenario all devices might be dropped, too. This causes 'del_gendisk' to be called, which will unregister the kobj_map->probe() function for all disk device numbers. When the device comes back the default ->probe() function is run which will call __request_module(), which will deadlock. As 'del_gendisk' typically does _not_ trigger a module unload the default ->probe() function is pointless anyway. This patch implements a dummy ->probe() function, which will just return NULL if the disk is not registered. This will avoid the deadlock. Plus it'll speed up device scanning.

Commit 64deb6ef "[SCSI] zfcp: Use status_read_buf_num provided by FCP channel" started using a value returned by the channel but only evaluated the value if the fabric link is up. Commit 8d88cf3f "[SCSI] zfcp: Update status read mempool" introduced mempool resizings based on the above value. On setting an FCP device online for the very first time since boot, a new zeroed adapter object is allocated. If the link is down, the number of status read requests remains zero. Since just the config data exchange is incomplete, we proceed with adapter open recovery. However, we unconditionally call mempool_resize with adapter->stat_read_buf_num == 0 in this case. This causes a kernel message "kernel BUG at mm/mempool.c:131!" in process "zfcperp<FCP-device-bus-ID>" with last function mempool_resize in Krnl PSW and zfcp_erp_thread in the Call Trace. Don't evaluate channel values which are invalid on link down. The number of status read requests is always valid, evaluated, and set to a positive minimum greater than zero. The adapter open recovery can proceed and the channel has status read buffers to inform us on a future link up event. While we are not aware of any other code path that could result in mempool resize attempts of size zero, we still also initialize the number of status read buffers to be posted to a static minimum number on adapter object allocation.

Commit 86a9668a "[SCSI] zfcp: support for hardware data router" reduced the initial block queue limits in the scsi_host_template to the absolute minimum and adjusted them later on. However, the adjustment was too late for the BSG devices of Scsi_Host and fc_host. Therefore, ioctl(..., SG_IO, ...) with request or response size > 4kB to a BSG device of an fc_host or a Scsi_Host fails with EINVAL. As a result, users of such ioctl such as HBA_SendCTPassThru() in libzfcphbaapi return with error HBA_STATUS_ERROR. Initialize the block queue limits in zfcp_scsi_host_template to the greatest common denominator (GCD). While we cannot exploit the slightly enlarged maximum request size with data router, this should be neglectible. Doing so also avoids running into trouble after live guest relocation (LGR) / migration from a data router FCP device to an FCP device that does not support data router. In that case, zfcp would figure out the new limits on adapter recovery, but the fc_host and Scsi_Host (plus in fact all sdevs) still exist with the old and now too large queue limits. It should also OK, not to use half the size as in the DIX case, because fc_host and Scsi_Host do not transport FCP requests including SCSI commands using protection data.

FCP device remains in status ERP_FAILED when device is switched online or adapter recovery is triggered while link to SAN is down. When Exchange Configuration Data command returns the FSF status FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE it aborts the exchange process. The only retries are done during the common error recovery procedure (i.e. max. 3 retries with 8sec sleep between) and remains in status ERP_FAILED with QDIO down. This commit reverts the commit 0df13847 (zfcp: Fix adapter activation on link down). When FSF status FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE is received the adapter recovery will be finished without any retries. QDIO will be up now and status changes such as LINK UP will be received now.
