This commits updates the Debian packaging bits to build scst-dbg package for kernel modules linked with debug kernel. SCST kernel modules linked with debug kernel need to packaged differently so that they can co-exist with SCST package for modules built for production kernel. The updates in packaging bits are minimal would only apply if KVERS environment variable is configured for debug kernel for TrueNAS SCALE. Signed-off-by:Umer Saleem <usaleem@ixsystems.com>

When CONFIG_NVME_FC is not set, fcport is unused: drivers/scsi/qla2xxx/qla_nvme.c: In function 'qla2xxx_process_purls_pkt': drivers/scsi/qla2xxx/qla_nvme.c:1183:20: warning: unused variable 'fcport' [-Wunused-variable] 1183 | fc_port_t *fcport = uctx->fcport; | ^~~~~~ While this preprocessor usage could be converted to a normal if statement to allow the compiler to always see fcport as used, it is equally easy to just eliminate the fcport variable and use uctx->fcport directly.

Unbreak the build for the previous commit against kernel versions before v5.8. See also commit 72e6329f86c7 ("nvme-fc and nvmet-fc: revise LLDD api for LS reception and LS request") # v5.8. -
Gleb Chesnokov authored
Introduce infrastructure in the driver to support the processing of unsolicited LS (Link Service) requests. This will involve the utilization of a new pass-up of unsolicited FC-NVMe request IOCB interface. Unsolicited requests will be submitted to the NVMe transport layer through nvme_fc_rcv_ls_req(). Any received LS responses, which are sent using xmt_ls_rsp(), will be forwarded to the firmware through the existing Pass-Through IOCB interface, responsible for sending FC-NVMe Link Service requests and responses.

The storage was not draining I/Os and the work load was not spread out across different CPUs evenly. This led to firmware resource counters getting overrun on the busy CPU. This overrun prevented error recovery from happening in a timely manner. By switching the counter to atomic, it allows the count to be little more accurate to prevent the overrun.

Fix race condition between Interrupt thread and Chip reset thread in trying to flush the same mailbox. With the race condition, the "ha->mbx_intr_comp" will get an extra complete() call. The extra complete call create erroneous mailbox timeout condition when the next mailbox is sent where the mailbox call does not wait for interrupt to arrive. Instead, it advances without waiting. Add lock protection around the check for mailbox completion.

Connection does not resume after a host reset / chip reset. The cause of the blockage is due to the FCF_ASYNC_ACTIVE left on. The gnl command was interrupted by the chip reset.

Link up failure occurred where driver failed to see certain events from FW indicating link up (AEN 8011) and fabric login completion (AEN 8014). Without these 2 events, driver would not proceed forward to scan the fabric. The cause of this is due to delay in the receive of interrupt for Mailbox 60 that causes qla to set the fw_started flag late. The late setting of this flag causes other interrupts to be dropped. These dropped interrupts happen to be the link up (AEN 8011) and fabric login completion (AEN 8014). Set fw_started flag early to prevent interrupts being dropped.

For each TMF request, driver iterates through each qpair and flushes commands associated to the TMF. At the end of the qpair flush, a Marker is used to complete the flush transaction. This process was repeated for each qpair. The multiple flush and marker for this TMF request seems to cause confusion for FW. Instead, 1 flush is sent to FW. Driver would wait for FW to go through all the I/Os on each qpair to be read then return. Driver then closes out the transaction with a Marker.

During NVMe queue creation, a new qpair is created. FW resource limit needs to be re-adjusted to take into account the new qpair. Otherwise, NVMe command can not go through. This issue was discovered while testing/forcing FW execution to fail at load time. Add call to readjust IOCB and exchange limit. In addition, get FW state command and require FW to be running. Otherwise, error is generated. Cc: stable@vger.kernel.org Signed-off-by:

This patch refactors scst_put_acg() to directly call kref_put() with a release callback that handles removal of scst_acg from the workqueue. This replaces the previous approach of queuing a work item for each kref_put() call, improving efficiency by reducing the number of queued work items.
