2022-08-31scsi: megaraid_sas: Replace one-element array with flexible-array member in ↵Gustavo A. R. Silva1-1/+1
MR_FW_RAID_MAP_DYNAMIC One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in struct MR_FW_RAID_MAP_DYNAMIC. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy().

2022-08-31scsi: qla2xxx: Avoid flush_scheduled_work() usageTetsuo Handa1-1/+1
Although qla2xxx driver is calling schedule_{,delayed}_work() from 10 locations, I assume that flush_scheduled_work() from qlt_stop_phase1() needs to flush only works scheduled by qlt_sched_sess_work(), for this loop continues while "struct qla_tgt"->sess_works_list is not empty.

2022-08-31scsi: qla2xxx: Always wait for qlt_sess_work_fn() from qlt_stop_phase1()Tetsuo Handa1-2/+2
Currently qlt_stop_phase1() may fail to call flush_scheduled_work(), for list_empty() may return true as soon as qlt_sess_work_fn() called list_del(). In order to close this race window, check list_empty() after calling flush_scheduled_work().

The kernel test robot reported the following sparse warning: arch/arm64/include/asm/cmpxchg.h:88:1: sparse: sparse: cast truncates bits from constant value (369 becomes 69) On arm64, atomic_xchg only works on 8-bit byte fields. Thus, the macro usage of LPFC_RXMONITOR_TABLE_IN_USE can be unintentionally truncated leading to all logic involving the LPFC_RXMONITOR_TABLE_IN_USE macro to not work properly. Replace the Rx Table atomic_t indexing logic with a new lpfc_rx_info_monitor structure that holds a circular ring buffer. For locking semantics, a spinlock_t is used.

2022-08-31scsi: lpfc: Fix unsolicited FLOGI receive handling during PT2PT discoveryJames Smart1-1/+0
During a stress offline/online test in PT2PT topology, target rediscovery can fail with a specific target vendor array. When the HBA transitions to online mode it is possible to receive an unsolicited FLOGI before processing the Link Up event. The received FLOGI will set the defer_flogi_acc_flag, which instructs the driver to wait until it transmits its own FLOGI before ACKing the received FLOGI. In this failure scenario, the link up processing clears the set defer_flogi_acc_flag before we have sent out the FLOGI. As the target has the higher WWPN and is responsible for sending the PLOGI, the target is stuck waiting for its FLOGI_ACC that the driver will never send. Remove the clear of defer_flogi_acc_flag from Link Up event processing. In this stress test case, the defer_flogi_acc_flag is cleared during the Link Down event processing anyways.
