{clear|set}_bit() can take an almost arbitrarily large bit number, so there is no need to manually compute addresses. This is just redundant.

Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic. Link: https://lore.kernel.org/r/5f975ef43f8b7306e4ac4e2e8ce4bcd53f6092bb.1658340441.git.christophe.jaillet@wanadoo.frTested-by:

Older tracing of driver messages was to: - log only debug messages to kernel main trace buffer; and - log only if extended logging bits corresponding to this message is off This has been modified and extended as follows: - Tracing is now controlled via ql2xextended_error_logging_ktrace module parameter. Bit usages same as ql2xextended_error_logging. - Tracing uses "qla2xxx" trace instance, unless instance creation have issues. - Tracing is enabled (compile time tunable). - All driver messages, include debug and log messages are now traced in kernel trace buffer. Trace messages can be viewed by looking at the qla2xxx instance at: /sys/kernel/tracing/instances/qla2xxx/trace Trace tunable that takes the same bit mask as ql2xextended_error_logging is: ql2xextended_error_logging_ktrace (default=1) Link: https://lore.kernel.org/r/20220826102559.17474-6-njavali@marvell.comSuggested-by:Daniel Wagner <dwagner@suse.de> Suggested-by:

On some platforms, the current logic of relying on finding new packet solely based on signature pattern can lead to driver reading stale packets. Though this is a bug in those platforms, reduce such exposures by limiting reading packets until the IN pointer.

This message is helpful to troubleshoot missing LUNs/SAN boot errors. It'd be nice to log it by default instead of only being enabled with debug. This user had an accidental/forgotten file modprobe.d/qla2xxx.conf w/ option qlini_mode=disabled from experiments with FC target mode, and their boot LUN didn't come up, as it skips SCSI scan, of course. However, their boot log didn't provide any clues to help understand that. The issue/message could be figured out w/ ql2xextended_error_logging, but it would have been simpler (or even deflected/addressed by user) if it had been there by default. And it also would help support/triage/deflection tooling. Expected change: scsi host15: qla2xxx +qla2xxx [0000:3b:00.0]-00fb:15: skipping scsi_scan_host() for non-initiator port qla2xxx [0000:3b:00.0]-00fb:15: QLogic QLE2692 - QLE2692 Dual Port 16Gb FC to PCIe Gen3 x8 Adapter.

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_PD_CFG_SEQ_NUM_SYNC and refactor the rest of the code accordingly. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays [0].

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.

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(). If this patch causes problems, please check commit c4f135d6 ("workqueue: Wrap flush_workqueue() using a macro"). We are on the way to remove all flush_scheduled_work() calls from the kernel.

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.

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.
