Title
scsi: lpfc: Fix SCSI I/O completion and abort handler deadlock
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix SCSI I/O completion and abort handler deadlock
During stress I/O tests with 500+ vports, hard LOCKUP call traces are
observed.

Diagram of lockup:
CPUA CPUB
---- ----
lpfc_cmd->buf_lock
phba->hbalock
lpfc_cmd->buf_lock
phba->hbalock
Fix by reordering the taking of the lpfc_cmd->buf_lock and phba->hbalock in
lpfc_abort_handler routine so that it tries to take the lpfc_cmd->buf_lock
first before phba->hbalock.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
