The pl vector has scount elements, i.e. pl[scount-1] is the last valid element. For maximum sized requests, payload->counter == scount after the last loop iteration. Therefore, do bounds checking first (with boolean shortcut) to not access the invalid element pl[scount]. Do not trust the maximum sbale->scount value from the HBA but ensure we won't access the pl vector out of our allocated bounds. While at it, clean up scoping and prevent unnecessary memset.

Duplicate fssrh_2 from a54ca0f6 "[SCSI] zfcp: Redesign of the debug tracing for HBA records." complicates distinction of generic status read response from local link up.

Commit a9277e77 "[SCSI] scsi_transport_fc: Getting FC Port Speed in sync with FC-GS" changed the semantics of FC_PORTSPEED defines to FDMI port attributes of FC-HBA/SM-HBA which is different from the previous bit reversed Report Port Speed Capabilities (RPSC) ELS of FC-GS/FC-LS. Zfcp showed "10 Gbit" instead of "4 Gbit" for supported_speeds. It now uses explicit bit conversion as the other LLDs already do, in order to be independent of the kernel bit semantics.

gcc 4.8 warns because the memset only clears sizeof(char *) bytes, not the whole buffer.

It does not make sense to translate ref tags with unexpected values. Instead we simply ignore them and let the upper layers catch the problem. Ref tags that contain the expected value are still remapped. Signed-off-by:

This fixes an issues seen where a Fabric RSCN event was received while the link was down, which resulted in repeated attempts to log back into the fabric, which then failed, resulting in the ibmvfc driver taking the host offline. Fix this by delaying taking any action regarding the fabric RSCN until the link comes back up. Signed-off-by:

If an abort request times out to the virtual fibre channel adapter, the ibmvfc driver will kick off a reset of the adapter. This patch ensures we wait for the both the abort request and the request being aborted to be completed prior to exiting the eh_abort handler. This fixes a bug where the ibmvfc driver was erroneously returning success to the eh_abort handler then later sending back a response to the same command. Signed-off-by:

- Changes to avoid discovering NPIV port as remote port by the other NPIV ports created on same physical port when all the NPIV ports are part of the same zone in a fabric. - Provided mechanism to support maximum number of target ports for a given initiator port (physical port + NPIV ports) irrespective of the way in which the initiator and target ports are zoned in the fabric. - Introduced module_parameter max_rport_logins to restrict number of remote ports discovery which includes target and initiator remote ports.
