2020-03-11scsi: qla2xxx: add ring buffer for tracing debug logsRajan Shanmugavelu1-3/+20
Having this log in a ring buffer helps to diagnose qla2xxx driver and firmware issues instead of having to reproduce the problem with extended_logging enabled. This saves cycles and helps when it is hard to reproduce problem.

2020-01-30scsi: qla2xxx: Fix unbound NVME response lengthArun Easi1-6/+0
On certain cases when response length is less than 32, NVME response data is supplied inline in IOCB. This is indicated by some combination of state flags. There was an instance when a high, and incorrect, response length was indicated causing driver to overrun buffers. Fix this by checking and limiting the response payload length.

Added logic to change the login process into an optional PRIL step for FC-NVMe ports as a separate operation, such that we can change type to 0x28 (NVMe). Currently, the driver performs the PLOGI/PRLI together as one operation, but if the discovered port is an NVMe port then we first issue the PLOGI and then we issue the PRLI. Also, the fabric discovery logic was changed to mark each discovered FC NVMe port, so that we can register them with the FC-NVMe transport later.

2016-01-07qla2xxx: Wait for all conflicts before ack'ing PLOGIAlexei Potashnik1-2/+2
Until now ack'ing of a new PLOGI has only been delayed if there was an existing session for the same WWN. Ack was released when the session deletion completed. If there was another WWN session with the same fc_id/loop_id pair (aka "conflicting session"), PLOGI was still ack'ed immediately. This potentially caused a problem when old session deletion logged fc_id/loop_id out of FW after new session has been established. Two work-arounds were attempted before: 1. Dropping PLOGIs until conflicting session goes away. 2. Detecting initiator being logged out of FW and issuing LOGO to force re-login. This patch introduces proper solution to the problem where PLOGI is held until either existing session with same WWN or any conflicting session goes away. Mechanism supports one session holding two PLOGI acks as well as one PLOGI ack being held by many sessions.
