scsi: lpfc: Move NPIV's transport unregistration to after resource clean up
mainline inclusion from mainline-v6.9-rc2 commit 4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9UMD0 CVE: CVE-2024-36952 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c -------------------------------- There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric. Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch. Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent.
