From c577ab7ba5f3bf9062db8a58b6e89d4fe370447e Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 16 Jun 2022 17:27:33 -0500 Subject: [PATCH] scsi: iscsi: Fix HW conn removal use after free If qla4xxx doesn't remove the connection before the session, the iSCSI class tries to remove the connection for it. We were doing a iscsi_put_conn() in the iter function which is not needed and will result in a use after free because iscsi_remove_conn() will free the connection.
