In Linux-4.16, drivers/staging/lustre/lustre/ptlrp/sec.c,
557. int ctx_refresh_timeout(...) { ....... 573. req->rq_cli_ctx->cc_ops->force_die(req->rq_cli_ctx, 0); ...... 575. }
For x86 kernel configuration, there is no assignment of the function pointer ".force_die" in the kernel code. So calling the function pointer in line 573 may cause a null pointer dereference.
Best wishes, Jia-Ju Bai
