scsi: qla2xxx: Fix response queue over-consumption in __qla_consume_iocb()<\/p>\n
qla24xx_process_response_queue() advances ring_ptr past the head IOCB
\nbefore dispatching, so by the time __qla_consume_iocb() runs, ring_ptr
\nalready points at the first continuation IOCB. The function however
\nlooped purex->entry_count times starting at ring_ptr. As entry_count
\nincludes the head, this consumed one entry too many: it stamped
\nRESPONSE_PROCESSED on the next, unrelated IOCB and advanced the ring
\npast it, silently dropping a legitimate firmware response. The head
\nIOCB’s signature was also never marked.<\/p>\n
Mark the head processed and account for it, then consume only the
\nentry_count – 1 continuation IOCBs, matching __qla_copy_purex_to_buffer().<\/p>\n","protected":false},"excerpt":{"rendered":"
