When the FCP channel returns a series of commands with the error status "test link", zfcp will send a series of ELS ADISC commands. This is technically no problem, but it is enough to only issue one test command per remote port. So, track whether a ELS ADISC command is already pending, and do not send a new one if there is already a pending command. Reviewed-by:

The default trace level is to only trace failed FSF commands. Thus it is not necessary to collect trace data for most FSF commands, since it will be thrown away later. Restructure the FSF/HBA trace infrastructure to first check the trace level in a inline function and only do the expensive data collection for matching trace levels. Reviewed-by:

The struct zfcp_adapter includes everything related to the debug traces. This introduces dependences between the definitions in zfcp_def.h and zfcp_dbf.h. Move all debug related data structures to a new data structure to break those dependencies and manage the debug data in zfcp_dbf.[hc]. Reviewed-by:

In certain error scenarios ports, rports are getting attached, validated and removed from the systems environment. Depending on the layer this occurs asynchronously. This patch fixes the few races which existed and ensures all references and cross references are cleared at the time they're invalid. In addition fc transports actions are only scheduled when required. Signed-off-by:

Universally, SCSI functions assume the lengths fed in are those of the buffer to DMA data to, not the lengths of the data minus the header. scsi_vpd_inquiry() assumed the latter and got it wrong, so fix up all the functions to use the correct assumption (and fix a bug where INQUIRY in SCSI-2 dcannot go over 255).

An IBM tape drive failed to complete a PERSISTENT RESERVE IN within the scsi cmd timeout. Error recovery was initiated and it sequenced from abort through taking the tape drive offline. The device was taken offline because it repeatedly responded to the TUR command issued by error recovery with a RESERVATION CONFLICT status. The tape drive was reserved to another system. This is perfectly legitimate response to TUR, and is one that an escalation of recovery is unlikely to clear. Further, escalation of recovery can have undesirable side effects on the operation of tape drives shared with other initiators. Instead of escalating recovery, error recovery should treat the RESERVATION CONFLICT response to the TUR as a good status, giving the issuer of the command the opportunity to handle the timeout and reservation conflict.

In nsp_cs_config there is a wrong struct nsp_cs_configdata allocation. It allocates only sizeof(pointer to nsp_cs_configdata) for a whole structure. Add a dereference to the sizeof to allocate sizeof(nsp_cs_configdata). Signed-off-by:

When the multiqueue mode fails to work, the driver falls back on single queue mode. This ensures that the firmware is reinitialized with single queue options and all the resources are readjusted accordingly. Signed-off-by:

The interrupt handler clears the interrupt status register for response updates in the base queue while working in the multique mode. This could lead to missing interrupt for async events, mail box completions etc. as these are also handled in the base queue. The fix ensures that the interrupt bit is not cleared for response updates in the ISR when the driver is working in multiqueue mode. Signed-off-by:

Handle the parameters provided by user thru multipath. This handler expects only 2 parameters and their value can either be 0 or 1. This code originates from the old dm-emc.c file. Appropriate changes have been made to make it work in the new design. Reported-by:

Chandra Seetharaman authored
When we moved the device handler functionality from dm layer to SCSI layer we dropped the parameter functionality. This path adds an interface to scsi dh layer to set device handler parameters. Basically, multipath layer need to create a string with all the parameters and call scsi_dh_set_params() after it called scsi_dh_attach() on a device. If a device handler provides such an interface it will handle the parameters as it expects them. Reported-by:

Right at the moment, hot removal of a device within an enclosure does nothing (because the intf_remove only copes with enclosure removal not with component removal). Fix this by adding a function to remove the component. Also needed to fix the prototype of enclosure_remove_device, since we know the device we've removed but not the internal component number Signed-off-by:

In a situation either with expanders or with multiple enclosure devices, hot add doesn't always work. This is because we try to find a single enclosure device attached to the host. Fix this by looping over all enclosure devices attached to the host and also by making the find loop recognise that the enclosure devices may be expander remote (i.e. not parented by the host).
