In GID_PT mode with lpfc_ns_query=1, a race condition between iterating the vport->fc_nodes list in lpfc_rscn_recovery_check() and cleanup of an ndlp can trigger a crash while processing the RSCN of another initiator from the same zone. During iteration of the vport->fc_nodes list, an ndlp is cleaned up and released. lpfc_dequeue_node() is called from lpfc_cleanup_node() leading to a bad ndlp dereference in lpfc_rscn_recovery_check(). Change list_for_each_entry() to list_for_each_entry_safe() in lpfc_rscn_recovery_check() to protect against removal of an initiator ndlp, while walking the vport->fc_nodes list.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
